FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with degenerative joint disease is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about degenerative joint disease, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to degenerative joint disease, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on degenerative joint disease. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to degenerative joint disease, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on degenerative joint disease. The Editors

CHAPTER 1. STUDIES ON DEGENERATIVE JOINT DISEASE Overview In this chapter, we will show you how to locate peer-reviewed references and studies on degenerative joint disease.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and degenerative joint disease, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “degenerative joint disease” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •

Stickler Syndrome: Report of Four Cases Source: Annals of Dentistry. 52(2): 23-27. Winter 1993. Summary: This article reports four patients with Stickler syndrome, an autosomal dominant connective tissue disorder. The characteristic features of Stickler syndrome include eye manifestations like myopia, vitreo-retinal degeneration, cataracts, and retinal detachment; facial changes of mid-face hypoplasia, broad nasal bridge, Pierre Robin sequence, and epiphyseal dysplasias; and premature degenerative joint disease. Since most of these patients will have cleft palate and facial anomalies, many of them initially consult oral surgeons. A correct diagnosis of the condition is of paramount importance because of the possibility of preventing blindness, and of its genetic implications. The authors report these four cases, and discuss features of other similar

syndromes to facilitate the early and correct diagnosis of affected individuals. The authors conclude that Stickler syndrome should be considered in any newborn infant with Pierre Robin sequence or cleft palate and small chin; and in all cases of dominantly inherited myopia with or without retinal detachments, dominantly inherited cleft palate, and dominantly inherited mild spondylo-epiphyseal dysplasia with or without joint laxity and slender tubular bones. 4 figures. 2 tables. 10 references. (AA-M).

Federally Funded Research on Degenerative Joint Disease The U.S. Government supports a variety of research studies relating to degenerative joint disease. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to degenerative joint disease. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore degenerative joint disease. The following is typical of the type of information found when searching the CRISP database for degenerative joint disease: •

KNEE

Principal Investigator & Institution: Kaufman, Kenton R.; Professor of Bioengineering; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-MAR-2006 Summary: (provided by applicant): Arthritis is one of the most common causes of functional limitation and dependency in the United States. Individuals with osteoarthritis restrict joint motion and limit activity in order to decrease their symptoms. Traditional, conservative medical treatment of osteoarthritis has been directed at improving functional status through reducing joint pain and inflammation and maintaining or restoring joint function. Exercise as an adjunct therapy in the clinical management of patients with osteoarthritis of the knee, however, is not uniformly accepted. In contrast, exercise has been shown to be effective for prevention and treatment of cardiovascular and metabolic disorders. Standard guidelines exist for aerobic exercise prescriptions. The focus of this study is to determine if these guidelines can also be applied to individuals with knee osteoarthritis. Patients with knee osteoarthritis will be randomized into a control group, a walking exercise group, and a stationary cycling exercise group. The individuals in the exercise groups will be required to exercise three times per week for one year using emerging public health recommendations for aerobic exercise in the adult and aging population. Patient 2 Healthcare projects are funded by the National Institutes of Health (NIH), Substance Abuse and Mental Health Services (SAMHSA), Health Resources and Services Administration (HRSA), Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDCP), Agency for Healthcare Research and Quality (AHRQ), and Office of Assistant Secretary of Health (OASH).

outcome will be assessed using objective gait analysis measurements, knee radiographs to quantify joint space narrowing, magnetic resonance imaging, a general health status questionnaire (SF-36), a disease/site specific questionnaire (WOMAC), and a visualanalog pain scale. All subjects will be studied at 0 and 52 weeks. The central hypothesis of this work is that aerobic exercise can be successfully implemented as an effective nonsurgical option for treatment of patients with early stages of knee osteoarthritis. In order to evaluate this hypothesis, the following specific aims are proposed: Specific Aim 1: Determine the effect of aerobic exercise on patients with knee osteoarthritis. Hypothesis A: Clinical Outcome measures will be better in patients enrolled in exercise programs that in control patients. Hypothesis B: Quantitative measures of lower extremity function will not decline over time in an effective aerobic exercise program. Specific Aim 2: Determine prognostic factors that effect outcome in patients with knee osteoarthritis. Hypothesis: A effective exercise prescription for adults with degenerative joint disease is dependent on knee compartment involvement, CIA stage, BMI, and type of exercise prescribed.

Project Title: CHONDROPROGENITOR CELLS IN MATURE CARTILAGE Principal Investigator & Institution: Lotz, Martin K.; Professor; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2007 Summary: (provided by applicant): Osteoarthritis (OA) is one of the most common musculoskeletal disorders in older individuals. Profound aging- associated changes in chondrocytes and cartilage extracellular matrix represent a major factor in OA pathogenesis. Although referred to as a degenerative joint disease, OA is an active cartilage remodeling process. Cells in OA cartilage are activated and not only produce matrix degrading enzymes, but also new extracellular matrix. The remodeling process ultimately fails because of an imbalance between matrix synthesis and degradation, because the newly formed cartilage is non-hyaline repair tissue and matrix is often abnormally calcified. Our preliminary studies suggest that adult human articular cartilage contains chondroprogenitor cells. The proposed experiments are based on the following hypotheses: 1) Mesenchymal progenitor cells are present in adult cartilage, and they can be isolated, expanded and induced to differentiate to multiple mature mesenchymal phenotypes. 2) The frequency, localization, activation and response patterns of mesenchymal progenitor cells are altered in aging and osteoarthritis. 3) The genetic basis of mesenchymal cell differentiation from the progenitor to the discrete subsets of mature chondrocytes can be established with DNA microarrays to define markers and regulators of this process. The following specific aims will test these hypotheses: 1) Determine the frequency and localization of progenitor cells in normal human articular cartilage using immunohistochemistry, cell isolation, flow cytometry and functional assessment of pluripotential differentiation. With these studies, we will develop markers for identification of progenitor cells and methods for isolation and expansion. 2) Analyze the presence of progenitor cells in aging and osteoarthritic human cartilage. Determine whether there is an aging- associated reduction in the number of progenitor cells, whether the cells have an impaired responsiveness to growth factors and whether progenitor cells are associated with the clusters of proliferating chondrocytes and areas of calcified cartilage. 3) With the DNA microarrays, define the genetic basis for the chondrocyte subsets in the various zones of normal human articular cartilage. Establish the relationship between bone marrow derived and cartilage derived progenitors and differentiated chondrocytes generated from them. The discovery of

6


progenitor cells in adult cartilage opens new perspectives to harness these cells in cartilage repair and raises the possibility that aging- associated changes in their frequency or function determine joint aging and that they contribute to the aberrant cartilage remodeling process in arthritis.

Project Title: COMPUTATIONAL FRAMEWORK FOR SIMULATING JOINT MECHANICS Principal Investigator & Institution: Fregly, Benjamin J.; Assistant Professor; Mechanical & Aerospace Engineering; University of Florida Gainesville, Fl 32611 Timing: Fiscal Year 2002; Project Start 01-MAY-2002; Project End 30-APR-2005 Summary: Mechanical loading and especially dynamic loading, is believed to play a major role in degenerative joint diseases. Furthermore, motion (i.e., kinematics) and loading (i.e., contact stresses) often interact to influence disease progression. Thus, knowledge of in vivo joint motion and loading during functional activities would help address this clinically significant issue. While dynamic imaging advances now permit accurate measurement of in vivo joint kinematics, a non-invasive experimental approach does not exist for measuring in vivo joint loading. Consequently, computer simulations have been used to develop predictions given estimates of the muscle forces acting on the joint. However, current rigid body and deformable modeling approaches are not able to calculate contact stress results during movement in critical joints such as the knee. A logical solution to this problem is to incorporate deformable joint models into a larger rigid body dynamic model, thereby obtaining the advantages of both approaches. However, the computation cost of such a hybrid approach is currently a limiting factor. This project therefore proposes the development of a parallel-processing framework for studying human joint mechanics. The specific aims of the project are as follows: (1) Create a dynamic musculoskeletal model with deformable knee joint contact. Deformable contact in the knee will be studied initially since the knee is the most commonly injured joint. (2) Incorporate this model into a parallel-processing optimization framework. Parallel processing will be used to reduce the computational time for predictive optimizations from weeks to a matters of hours. (3) Evaluate the model's ability to predict experimental movement data. Pre-existing experimental movement data will be used to evaluate the model's ability to predict motion and ultimately joint contact stresses. The resulting functional virtual human model can then be used for basic research and clinical applications. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: DIFFUSE OPTICAL TOMOGRAPHY OF OSTEOARTHRITIS Principal Investigator & Institution: Jiang, Huabei; Professor; Physics and Astronomy; Clemson University 300 Brackett Hall Clemson, Sc 296345702 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 30-APR-2008 Summary: (provided by applicant): Osteoarthritis (OA), or degenerative joint disease, is the most common form of joint diseases. It is a slowly progressing disease, and a major cause of morbidity in the population over 50, affecting more than 40 million Americans. It also imposes considerable expense on the health care system. While there is currently no cure for this disease, recent studies have shown that the progression of articular damage may be modified by medical or surgical intervention if the disease is detected early. These studies coupled with recent developments in gene therapy have generated substantial demand for noninvasive techniques for detecting early changes in

the joints, when intervention is likely to have its greatest effect. X-ray radiography is excellent for imaging hard tissues and has been a routine modality for examining OA, primarily for advanced OA stages. The limitation of x-ray is its incapability for imaging soft tissues in the joints as well as its incapability for obtaining physiological information related to the functioning of OA. Diffuse optical tomography (DOT) is a promising method for detecting changes in cartilage and inflammation process in synovium. It can also provide information about the functioning and progression of OA. However, DOT has limited spatial resolution comparing to x-ray. To overcome this limitation, in this application we propose a combined x-ray/DOT approach so that we can use the x-ray images as structure guidance for DOT reconstruction. We aim to advance 3D DOT imaging of joint tissue co-registered with 3D x-ray tomosynthesis. Our specific aims include (1) investigation of several tomosynthetic reconstruction methods for 3D x-ray imaging, (2) development of algorithms for segmentation of 3D xray images, (3) development of 3D rendering environment, (4) advanced DOT reconstruction methods including automatic adaptive meshing scheme, parallel computing and a higher-order diffusion model, (5) design, construction and testing of a combined digital x-ray/optical imaging system for 3D imaging of joint tissue, (6) evaluation and optimization of this system using tissue phantom experiments, and (7) testing and evaluation of the combined xray/ optical imaging system in human subjects. If successful, the proposed mulfi-modality imaging method will have a major impact on the ability to make an early and appropriate therapeutic intervention, routinely monitor the progression/clinical outcome and assist in evaluating new treatment modalities.

Project Title: EARLY DIAGNOSIS OF GROWTH DISORDERS UING MR IMAGING Principal Investigator & Institution: Jaramillo, Diego; Massachusetts General Hospital 55 Fruit St Boston, Ma 02114 Timing: Fiscal Year 2002; Project Start 15-JUL-1994; Project End 30-JUN-2005 Summary: (provided by applicant): The goal of this research is the detection of epiphyseal ischemia and prediction of its growth sequelae using novel non-invasive magnetic resonance (MR) approaches. In animal models, we propose to determine the earliest changes in ischemia, to differentiate early from late ischemia leading to avascular necrosis; and to predict the deverlopment of growth arrest. In addition to conventional MR measures (proton density and T2 relaxation), we will investigate perfusion-related changes by early gadolinum (Gd) enhanced imaging; and diffusion related changes by line diffusion scanning and diffusion tensor imaging. We will also evaluate disturbances of the cartilaginous matrix including glycosaminoglycan depletion revealed by delayed GD enhanced imaging, and collagen content by magnetization transfer imaging. The major hypotheses are that MR parameters can 1) detect early ischemia, 2) differentiate early from late ischemia leading to sequelae, and 3) predict growth deformity through MR parameters that reflect tissue structure and vascularization of the immature epiphysis. Epiphyseal ischemia is a pathogenic pathway shared by many common pediatric disorders. Ischemia leading to avascular necrosis of the femoral head frequently causes hip deformity and disability in childhood. A hip that grows abnormally also predisposes to degenerative joint disease in adult; more than half of all adults with osteoarthritis of the hip suffered hip diseases as children. Imaging of cartilaginous disorders serves to guide early therapy, prevent or minimize deformity, and detect children predisposed to premature cartilage degeneration in adulthood. The specific aims are to: 1) determine the MR tissue

8


characteristics of normal epiphyseal cartilage. Specifically, we wish to test whether the greater cellularity and vascularization of immature epiphyseal cartilage result in different MR tissue characteristics; 2) in early ischemia, determine temporal and spatial differences between diffusion imaging, T2 maps and Gd-enhanced imaging; 3) in prolonged ischemia, determine which MR parameters best predict irreversible damage; and 4) in a model of avascular necrosis, determine which MR parameters predict abnormal growth.

Project Title: IMMUNOPROBES FOR LUBRICIN FROM HUMAN SYNOVIAL FLUID Principal Investigator & Institution: Jay, Gregory D.; Associate Professor; Rhode Island Hospital (Providence, Ri) Providence, Ri 029034923 Timing: Fiscal Year 2002; Project Start 15-AUG-2000; Project End 31-JUL-2004 Summary: Specific or related causes in the pathogenesis of osetoarthritis remain unclear despite a great deal of investigation. This justifies a new venue of research into other factors involved in degenerative joint disease. The study of joint lubrication, biotribology, has been fraught with conflicting theories, failure to adequately use molecular techniques, standardize merchanical assays and assign clinical importance to lubrication by synovial fluid. This investigation addresses the molecular of synovial lubrication of animal joints. A considerable literature has demonstrated that these rubbing and pressurized surfaces (i.e., bearings) have low frictional properties (1-4). These properties arise in part from the slippery nature of articular cartilage. Most reports actually deal with the rheology of synovial fluid and may incorrectly assume that its viscosity is the basis for joint lubrication (5-10). Direct measurements documents that synovial fluid lowers the coefficient of friction between cartilage bearings and certain artificial surfaces. A lubricating glycoprotein termed "lubricin" from synovial fluid is responsible for this but no one has proposed a mechanism of how it does so or how to study it in vitro. An arthrotripsometer composed of latex oscillating against glass employed by the PI reproduced critical findings of previous studies using cartilage bearings. It isolated boundary mode lubrication measuring devices previously employed by others. Synovial fluid, saliva, and detergents are the only substances which display this activity (11). The observation that lubricin lubricated the latex: glass bearing is a recent discovery by the PI. This provides an experimental opportunity to implicate failed lubrication in the occurrence of degenerative joint disease in a large number of patients and to causally link this measure to lubricin. A low coefficient of friction (mu) is no necessarily a measure of wear protection but synovial fluid does in fact confer this property to cartilage (12). It is unknown if the absence or paucity of lubricin is significant to the initial or continued pathogenesis of either osteoarthritis or rheumatoid arthritis. This principal goal of this investigation is to develop new immunological probes and with these identify the concentration of lubricin in synovial fluid extracted from healthy and arthritic human joints.

Project Title: IN VIVO RABBIT MODEL OF FINGER MUSCOLOSKELETAL DISORDERS Principal Investigator & Institution: King, Karen B.; Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-AUG-2007

Summary: (provided by applicant): The ongoing rise in costs and morbidity associated with occupational musculoskeletal disorders (MSDs) demands the investigation of known risk factors for injury. Repetition of movement, forceful loading and their combination (repetitive loading) are risk factors for MSDs. These happen to be some of the few modifiable risk factors for MSDs of the hand and other joints. This project proposes to use an in vivo animal model of repetitive finger joint loading to elucidate the relative risks of these factors (repetition and combined force and repetition). Finger joint loading is used to simulate hand intensive tasks found in the workplace to test the following hypothesis: The combination of force and repetition is an occupational risk factor for MSD. This project will quantify the structural and molecular changes in joint tissues due to repetitive loading. And finally, this project will determine the threshold of repetitive loading in a dose-response study. The long term goals of this study are to 1) determine the relative contributions of individual biomechanical characteristics of finger joint loading, namely repetition, force level, and duration of exposure; and 2) demonstrate causality between these biomechanical risk factors, cellular response, tissue damage, and injury. The results of this mechanobiology project will lead to guidelines for effective interventions of MSDs of the hand joints such as osteoarthritis (OA) or degenerative joint disease (DJD). This project directly addresses the National Occupational Research Agenda (NORA) in 1) developing a quantitative dose-response model identifying dose-response relationships, 2) determining whether the injury response of the tissue has more to do with repetition of loading or level of peak load, and 3) identifying the ultrastructural injury and biochemical alterations associated with physical loading.

Project Title: LASER ASSISTED CARTILAGE REPAIR USING COLLAGEN ADHESIVES Principal Investigator & Institution: Soltz, Barbara A.; Conversion Energy Enterprises 81 Pine Brook Rd Spring Valley, Ny 10977 Timing: Fiscal Year 2002; Project Start 17-APR-2002; Project End 31-OCT-2002 Summary: Articular cartilage damage affects millions of people. This condition is exacerbated by an ageing but increasingly more active population. The two portentous independent variables associated with inferior treatment of articular cartilage lesions are healing response and cartilage regeneration. Laser-assisted welding using a derivatized collagen solder may aid in the prevention of progressive degenerative joint disease and may augment or ultimately replace total joint arthroplasty. We have assembled a multidisciplinary team to investigate the efficacy of laser activated collagen formulations as an adhesive and as an acellular graft that permits and/or promotes cell invasion. Laser operating parameters will be optimized to promote strong solder crosslinks to cartilage. An integrated temperature controller will be used to prevent peripheral tissue damage. A laser handpiece will be modified for use in the animal studies. Custom designed equipment will be used to accurately measure previously unknown values for inherent solder strength, strength of the repair and type of failure mode. Histology will assess the potential to promote cell invasion and synthesis of new extracellular matrix. It is anticipated that the Phase I results will lay the foundation for further animal studies and clinical trials in subsequent Phase II and Phase III projects. PROPOSED COMMERCIAL APPLICATIONS: The development of laser procedures to repair full thickness articular defects will benefit the millions of people who are suffering from osteoarthritis.

Project Title: MECHANICS OF THE MCL IN NORMAL AND ACL DEFICIENT KNEES Principal Investigator & Institution: Weiss, Jeffrey A.; Bioengineering; University of Utah Salt Lake City, Ut 84102

Associate

Professor;

Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 31-AUG-2004 Summary: Knee ligament injury can lead to ligamentous laxity, joint instability and degenerative joint disease. Methodologies that improve the diagnosis, treatment and prevention of ligament injuries are crucial to prevent this progression. The medial collateral ligament (MCL) is one of the most commonly injured knee ligaments, provides primary stabilization against valgus rotation, and is a secondary restraint to anterior tibial translation and external tibial rotation. The structure experiences extreme variations in strain as a function of knee flexion angle. The broad aims of this project are to develop and validate a constitutive model for the MCL, a finite element model of the superficial MCL, and to determine the stress/strain distribution within the MCL under varus-valgus (V-V) torques and anterior-posterior (A-P) tibial force in intact, ACLdeficient, and ACL-deficient+meniscus compromised knees. Following acquisition of volumetric CT data for individual knees, experimental kinematic testing will be performed under V-V and A-P loading conditions as a function of knee flexion angle. Knee kinematics and MCL surface strains will be continuously monitored during all kinematic testing. The MCL will then be isolated from the joint to measure regional in situ strain at 0 degrees knee flexion. Material testing of the MCL will be performed to determine coefficients for a three-dimensional constitutive model. Using the volumetric CT data, detailed geometric and finite element (FE) models of the MCL, distal femur and proximal tibia will be constructed. Appropriate boundary conditions, including representation of contact between the MCL and bones, will be applied to the model, using the experimentally measured joint kinematics to drive the motion of the model. The experimentally measured in situ strains will be applied to the FE model using numerical algorithms developed by the PI. Predictions of MCL stress/strain under V-V and A-P loading will be obtained from FE simulations. The regional MCL strain predictions will be statistically compared with experimental measurements to validate the model. The results for the normal and ACL-deficient knee will be compared to determine the effect of ACL deficiency on MCL stresses under V-V and A-P loading. Information obtained from this study will yield a detailed understanding of the function of the superficial MCL and its propensity for injury in the ACL-deficient and meniscuscompromised knee. The methods developed in conjunction with this research will facilitate future modeling of other ligamentous structures, and the eventual modeling of entire joints. This work will form the basis for the PI's long term research program aimed at the computational modeling of ligaments and joints.

irradiation in air continues to be recognized as a significant clinical problem limiting the longevity of total joint arthroplasties, which represent the standard of care for patients with advanced degenerative joint disease. Oxidative degradation of polyethylene has been associated with accelerated wear, brittle fracture, and delamination of total joint replacement components. Although it is now recognized that the degradation of polyethylene plays an important role in the damage mechanisms of orthopaedic components, it is still unclear the extent to which the mechanical degradation of polyethylene relates to the overall clinical performance of total hip arthroplasty, due in part to the logistical difficulty in tracing the sterilization and shelf aging history of the components, and also due to the experimental difficulty in directly measuring the mechanical behavior of retrieved implants. The range of mechanical behavior associated with traceable, clinically retrieved orthopedic components is critically needed to guide the development of improved polyethylenes, such as the highly crosslinked polyethylenes which have recently been introduced into clinical practice for total hip arthroplasty. The purpose of this proposed research is to examine the influence of mechanical degradation after implantation on the clinical performance of metal-backed acetabular components for total hip arthroplasty.

Principal Investigator & Institution: Tiller, George E.; Pediatrics; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2002; Project Start 15-APR-1999; Project End 31-MAR-2005 Summary: Osteoarthritis is a chronic debilitating disease which affects up to 1/3 of the adult population. Growing evidence suggests that genetic factors influence its development, and a better understanding of inherited chondrodysplasias will undoubtedly shed light on the processes common to all degenerative joint disease. Spondyloepiphyseal dysplasia tarda (SEDT) is a chondrodysplasia which is characterized by disproportionate short stature, X-linked inheritance, and degenerative osteoarthritis. The goals of this project are 1) to localize and isolate the gene for SEDT, 2) to identify the molecular alterations responsible for this disease, and 3) to gain insight into the biological function of the gene product. We have studied three SEDT families, including one large pedigree which includes 16 living affected males and at least 20 carrier females. DNA linkage analysis indicates that the SEDT phenotype in these families cosegregates with polymorphic markers on chromosome Xp22, a region previously defined as harboring the SEDT disease gene. To reduce the size of the candidate area, we will expand the sample size within our families, ascertain additional families, and verify locus order by physical methods. We will identify candidate genes which both map to the region and are transcribed in cartilage using expressed sequence tagged sites (ESTs) and cDNA selection techniques. Candidate genes will be prioritized for mutation analysis based on their homology to known genes. Prime candidates will be analyzed for mutations by SSCP and direct DNA sequence analysis of genomic DNA and/or cDNA from affected individuals. This research will directly benefit families with SEDT by enhancing genetic counseling and facilitating early definitive diagnosis for individuals at risk, therefore improving their clinical care. The expression pattern and function of the SEDT gene may provide clues for designing therapeutic modalities for affected individuals. Moreover, we anticipate that the molecular delineation of SEDT will have a significant impact on our understanding of basic mechanisms responsible for

Principal Investigator & Institution: Masuda, Ikuko; Medicine; Medical College of Wisconsin Po Box26509 Milwaukee, Wi 532260509 Timing: Fiscal Year 2002; Project Start 04-AUG-1998; Project End 31-JUL-2004 Summary: (Adapted from the Applicant's Abstract): CPPD crystal deposition in human articular cartilage is a common age-related event, and clinically and epidemiologically associated with degenerative joint disease, another age-related event. CPPD causes arthritis and subsequent cartilage degradation. However, the molecular mechanisms involved in CPPD formation in articular tissues remain undetermined. The goal of this grant proposal is to define the molecular basis of calcium pyrophosphate dehydrate (CPPD) crystal deposition disease. Elevated nucleotide pyrophosphohydrolase (NTPPHase) activity has been observed in CPPD-containing joint fluids and in detergent extracts of CPPD crystal-encrusted degenerated cartilage. NTPPHase catalyzes the joint fluids of PPi from ATP and other nucleotides. Several studies are consistent with the hypothesis that the bulk of PPi production occurs via the hydrolysis of extracellular ATP by ectoNTPPHase. NTPPHase exists in several molecular forms, including a 127kD sedimentable vesicle-associated NTPPHase, and two soluble forms of molecular masses of 100 and 61kD. The 127kD protein appears to represent the mature form of NTPPHase, while the 100 and 61kD forms represent soluble proteolytic fragments of the 127kD NTPPHase. The applicants have successfully cloned a partial cDNA encoding the 61kD NTPPHase fragment of the porcine 127kD NTPPHase from a porcine chondrocyte cDNA library, and also cloned its human homologue from a human chondrocyte cDNA library. Overall, their research has focused on defining the molecular properties of these NTPPHases. The Specific Aims of the current proposal are to: 1) clone the human homologue of the 127kD NTPPHase from a human chondrocyte cDNA library; 2) characterize the enzymatic activity and immunological properties of human 127kD NTPPHase; 3) molecularly characterize the gene that encodes the human NTPPHase; and 4) correlate the expression of the human NTPPHase during aging and disease. It is suggested (by the applicant) that these investigations will provide the framework for the investigators' long-term goal, which is to identify populations at risk, and to design therapeutic approaches, at either the level of transcription or inhibitors of the enzymatic activity of NTPPHase. It is hoped that these studies will lead to therapies to reduce ePPi accumulation and reduce subsequent cartilage degeneration. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: NOVEL OA-MARKERS BY INTEGRATING BASIC BIOLOGY AND CLINIC Principal Investigator & Institution: Heinegard, D K.; University of Lund Box 1703 Lund, Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-AUG-2008 Summary: Provided by Applicant): Joint disease like osteoarthritis affects a very large proportion of the population, in the order of 10%, with loss of motion, pain and dysfunction and impaired quality of daily activities. The cost to society rank among the highest for any disease group. Therapy existing today is very limited and largely rely on

joint replacement. A prerequisite for development of novel therapy is to delineate mechanisms in the progressive joint destruction as well as novel diagnostic procedures that can identify patients with active disease and evaluate therapy that modifies disease progression. This study is to develop new diagnostic procedures that provide insights in mechanisms in osteoarthritis development and thereby facilitate new advances in therapy as well as provide means for identifying patients at risk and for monitoring therapeutic effects. The specific aims are: 1 ) To define processes in the articular cartilage and bone during development of osteoarthritis by monitoring for release of cartilage and bone constituents; 2) To identify new molecules that show a unique distribution to articular cartilage, meniscus and bone in the joint and have potential as molecular markers of processes affecting these structures; 3) To define specific proteolytic cleavage by the identification of neoepitopes formed by specific proteinases active in cartilage destruction. Specific antibodies developed will be used for assays of processes in the tissue leading to proteolytic release of specific fragments; 4) To search for the identity of enzymes accomplishing specific proteolysis of target molecules; 5) To identify disease mechanisms by focusing on bioactive markers that contain active domains that recognize specific ligands on cells of bone, cartilage and synovium and/or can bind to other factors present in the synovial fluid. Assays will be developed for active fragments and their role in the process in the joint will be investigated; 6) To develop quantitative immunoassays for identified proteins that are altered in articular cartilage of degenerative joint disease; 7) To evaluate newly developed assays by analyses of well defined human patient cohorts as well as animal models with or without specific intervention.

Project Title: NOVEL X-RAY TECHNOLOGY FOR DEGENERATIVE JOINT DISEASE Principal Investigator & Institution: Kuettner, Klaus E.; Rush University Medical Center Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2007 Summary: We propose a program to integrate biomedical (Rush Medical College) with bioengineering (Illinois Institute of Technology and Massachusetts Institute of Technology) approaches to test and refine a novel X-ray technology for the diagnosis of joint pathology, particularly osteoarthritis. This technology may aid in the development of disease modifying agents and treatment strategies for the prevention and treatment of joint diseases. This project utilizes a novel synchrotron x-ray technique called diffraction enhanced imaging (DEI) which derives dramatic gains in contrast over conventional radiographs by exploiting x-ray refraction and scatter rejection (extinction) in addition to the usual absorption of conventional radiography. This technique, originally developed for mammary carcinoma imaging analyzes soft tissue as high contrast images with very high (greater than 0.05mm) spatial resolution. Although the synchrotron is currently used for DE imaging, the technique is not, in principle, tied to it. We have already shown that DEI is capable of imaging normal and degenerated articular cartilage of synovial joints showing features unique to this type of imaging using exposure times comparable to those of ordinary radiography. Beginning in the first year, we will interpret the cartilage and bone data obtained through our DEI methodologies by using the biological profiles of the matrix components as garnered through morphologic, biochemical and biophysical analysis. Some of the features observed in the DE images are not immediately explainable in molecular, chemical or structural terms. By using a unique integrated experimental approach, correlating biochemical and

14


morphological tissue profiles with DE images, we hope to refine the overall DEI system for the detection of joint disease and, potentially, for other pathologies. We will image human and animal synovial joints and begin the refinement of the imaging technique for the optimal identification of early cartilage lesions. Animal models of cartilage degeneration will be used particularly for DE imaging of cartilage prior to visible signs of degeneration. Beginning in year two, we will image human cartilage that has been biomechanically damaged under controlled conditions for observation through DE imaging. We will also begin developing new DEI methodologies to produce images conveying more comprehensive information about the properties of the cartilage tissue, first for planar and then for 3D computed tomography. Throughout years one through five of the proposed project, there will be an iterative process of comparing biological analytical data with imaging data for the refinement of the DEI technique for joint tissues. Our long-term goal is to identify and localize initial phases of cartilage degeneration and follow their progression with the ultimate aim of monitoring disease progression and therapeutic interventions.

Project Title: SHEAR STRESS AND CHONDROCYTE GENE EXPRESSION Principal Investigator & Institution: Smith, Robert L.; Professor-Research; Functional Restoration; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 15-SEP-2000; Project End 31-AUG-2004 Summary: While the precise etiology of the degenerative joint disease, osteoarthritis, is unknown, clinical manifestations of pain and disability are most often associated with inappropriate mechanical loading. As evident at surgery, focal erosion of articular cartilage culminates in loss of joint function and remains the final common pathway in all cases of osteoarthritis irrespective of cause. The goal of this study is to determine the cellular mechanisms by which mechanical loading influences cartilage matrix synthesis and degradation. In the joint, cartilage cells, chondrocytes, are subject to a complex array of stresses and strains. Our work shows that normal chondrocytes in culture react metabolically to univariate mechanical stimulation applied either as intermittent hydrostatic pressure or as fluid- induced shear stress. The hypothesis to be tested here is that distinct intracellular signaling pathways underlie the articular cartilage response to the two forms of mechanical stimulation. Fundamental knowledge exists regarding the effects of the proinflammatory cytokine, interleukin-1, on inhibition of cartilage extracellular matrix macromolecule synthesis and induction of cartilage degrading enzyme synthesis by chondrocytes. However, the effects of mechanical loading on the expression of articular chondrocyte degradative enzymes in the presence of IL-1 remain unclear. The specific aims will quantify effects of shear stress (SS) and intermittent hydrostatic pressure (IHP) on human osteoarthritic articular chondrocytes in vitro to: (1) Test the hypothesis that IHP and SS differentially modulate extracellular matrix macromolecule expression in OA versus normal chondrocytes; (2) Test the hypothesis that IHP and SS modulate IL-1beta induced inhibition of proteoglycan and type II collagen synthesis in OA and normal chondrocytes; (3) Test the hypothesis that IHP and SS alter endogenous MMPs and aggrecanase expression in OA and normal chondrocytes; (4) Test the hypothesis that IHP and SS alter IL-1beta induced expression of MMPs and aggrecanse in OA and normal chondrocytes. The expected result is that SS and IHP will show dissimilar capacities to overcome the IL-1 induced shift of chondrocyte metabolism from cartilage maintenance to matrix destruction. The results of this study will be of importance to the fields of orthopaedics, rheumatology and rehabilitation medicine. The techniques will involve analysis of proteoglycan and

Principal Investigator & Institution: Chen, Qian; Professor; Rhode Island Hospital (Providence, Ri) Providence, Ri 029034923 Timing: Fiscal Year 2002; Project Start 01-SEP-1998; Project End 29-FEB-2004 Summary: Degenerative joint disease or osteoarthritis (OA) is one of the most common disabling diseases affecting middle-aged and older people. It is characterized by the breakdown of an unstable matrix network in cartilage. To better understand the pathogenic process of OA, it is necessary to examine how the matrix structure is stabilized in mature cartilage, and what causes destabilization of such a structure. The long term career goal of the candidate is to analyze the molecular mechanisms of stabilizing matrix networks in mature cartilage. The immediate research plan is to determine the role of cartilage matrix protein (CMP), a mature cartilage specific protein that interacts with both collagenous and non-collagenous matrix components to form a filamentous network, in the stabilizing process. As a newly independent investigator, the candidate is applying for an RCA to protect his research time at 95 percent level and to continue his productive record. This proposal for the next five years of research is based on candidate's recently funded FIRST Award from NIH and the Arthritis Investigator Award from Arthritis Foundation. It contains four specific aims: 1) To characterize the interaction sites between CMP and matrix network. The location and properties of the adhesion sites will be determined by examining the interaction of a series of recombinant CMPs with matrix networks in a primary chondrocyte culture. 2) To analyze the nature of the covalent crosslinking of CMP in cartilage matrix. A monoclonal antibody will be used to determine whether CMP is a substrate for tissue transglutaminase. 3) To determine whether the disruption of interaction and crosslinking of CMP will result in a misassembled or unstable matrix network that is subject to degeneration. The dominant negative CMP constructs will be expressed in cartilage by retroviral infection. The effects will be examined by immunohistochemical analysis. 4) To examine whether abnormal CMP gene expression in human OA articular cartilage leads to a defective matrix structure. In situ hybridization and electron microscopy will be used to analyze abnormal synthesis and assembly of CMP in OA cartilage. These data will contribute not only to our basic understanding of cartilage matrix assembly, but also to the development of methods for prevention and treatment of cartilage degeneration.

Recent studies have emphasized the importance of osteoarthritis (degenerative joint disease) and inflammation in the pathogenesis of

16


temporomandibular joint (TMJ) disorders. The growth of tissues in vitro for in vivo transplantation and repair (tissue engineering) has recently been demonstrated to have immense potential. Recent studies have demonstrated the ability to grow cartilage and meniscal constructs in vitro, for in vivo transplantation into knee joints. The objective of this proposal is to develop cartilage and disc tissue representative of TMJ tissues by tissue engineering. It is anticipated that the in vitro growth of the tissue engineered TMJ cartilage and disc constructs will be enhanced with the application of mechanical load and growth factors. Our governing hypothesis is that tissue engineered constructs similar to TMJ tissues can be generated using scaffolds with TMJ cells, and cultured under defined mechanical loads with selected growth factors. Specific Aim 1 is to (a) determine the capacity of cells from the articular cartilage and the disc of the TMJ to proliferate and maintain a phenotype that will allow construct formation in vitro; and (b determine the scaffold(s) that will support construct growth and generate a tissue similar to that of normal TMJ cartilage and disc. Specific Aim 2 is to determine the effect of (a) static and cyclic compressive loads, (b) fluid induced shear stress, and (c) growth factors (IGF1, TGFb and FGF) on the gene expression and synthesis of aggrecan, biglycan, decorin, caollgen I and II, in the bovine TMJ articular cartilage, and the posterior band and intermediate zone of the disc. Based on these results, we will develop a bioreactor system that will support tissue growth with imposition of the mechanical loads and stresses as identified in (a), (b) and (c). Specific Aim 3 is to determine the effect of specifically selected mechanically loading regimes, and potentially growth factors (as determined in Specific Aim 2), on the ability of cell-seeded scaffolds (as selected in Specific Aim 1) to form cartilage and disc tissue in vitro. The objective will be to use these variables to modulate tissue growth toward the properties and composition of normal TMJ tissues. The completion of these studies will provide the method for tissue engineering TMJ tissues appropriate for transplantation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: TRANSDUCTION OF MECHANICAL SIGNALS IN CARTILAGE Principal Investigator & Institution: Towle, Christine A.; Massachusetts General Hospital 55 Fruit St Boston, Ma 02114 Timing: Fiscal Year 2003; Project Start 16-SEP-2003; Project End 31-AUG-2006 Summary: (provided by applicant): Osteoarthritis (OA) is a common degenerative joint disease that is the leading cause of chronic disability in the United States. OA primarily afflicts those over 50 years of age, but it is distinct from normal aging. The hallmark of the disease is the loss of articular cartilage, a tissue that is essential for normal joint function. The causes of osteoarthritis have not been fully determined, but risk factors include abnormal mechanical loading related to joint injury, joint instability, joint malalignment, and obesity. As such, there is immense interest in understanding the effects of mechanical stimuli on articular cartilage. The hypothesis underlying this proposal is that cartilage deformation on weight-bearing is an important stimulant of progressive degenerative change to the articular cartilage. Preliminary data demonstrate that the inhibition of proteoglycan synthesis that is caused by static compression in calf articular cartilage is ameliorated by IL-1 receptor antagonist and by inhibition of caspase activity, supporting the concept that IL-1 receptors and caspase(s) are critical elements in mechanical signaling and down-stream metabolic effects. The beneficial effect of IL-1 receptor antagonist is an exciting finding that begins to define a signaling pathway activated by mechanical stimulus in cartilage. The broad goal of this proposal is to delineate the linkage between static mechanical compression and the down-regulation of extracellular matrix biosynthesis in cartilage. The goal is approached through four

Studies

17

Specific Aims. First, studies will evaluate the IL-1 receptor dependency of compression effects on various metabolic parameters in surface and middle-depth bovine cartilage, and in human normal and OA cartilage. Second, studies will identify the specific caspases that are activated in compressed tissue in an attempt to clarify the involvement of caspase(s) in modulating cartilage metabolism. Third, studies will examine the phosphorylation status and levels of selected molecules in the signaling cascade activated by compression, with a focus on IL-1 receptor and caspase dependency. Fourth, studies will examine the role of IL-1 receptor and caspases on the metabolic effects of hyperosmotic and pH-buffered media, which mimic some of the cellular and physiochemical changes that occur with mechanical compression. The research is expected to define the mechanism(s) whereby cartilage deformation activates IL-1 receptor-dependent signaling pathways and modulates cartilage metabolism.

CHAPTER 2. NUTRITION AND DEGENERATIVE JOINT DISEASE Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and degenerative joint disease.

Finding Nutrition Studies on Degenerative Joint Disease The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail: [email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “degenerative joint disease” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

7

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 4. DISSERTATIONS ON DEGENERATIVE JOINT DISEASE Overview In this chapter, we will give you a bibliography on recent dissertations relating to degenerative joint disease. We will also provide you with information on how to use the Internet to stay current on dissertations. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical dissertations that use the generic term “degenerative joint disease” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on degenerative joint disease, we have not necessarily excluded non-medical dissertations in this bibliography.

Dissertations on Degenerative Joint Disease ProQuest Digital Dissertations, the largest archive of academic dissertations available, is located at the following Web address: http://wwwlib.umi.com/dissertations. From this archive, we have compiled the following list covering dissertations devoted to degenerative joint disease. You will see that the information provided includes the dissertation’s title, its author, and the institution with which the author is associated. The following covers recent dissertations found when using this search procedure: •

A comparison of the pattern of involvement of degenerative joint disease between an agricultural and non-agricultural skeletal series (Averbuch, Indian Knoll) by PIERCE, LORNA KATHRYN COLLINS, PHD from THE UNIVERSITY OF TENNESSEE, 1987, 333 pages http://wwwlib.umi.com/dissertations/fullcit/8810387

•

CHAPTER 5. PATENTS ON DEGENERATIVE JOINT DISEASE Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “degenerative joint disease” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on degenerative joint disease, we have not necessarily excluded non-medical patents in this bibliography.

Patents on Degenerative Joint Disease By performing a patent search focusing on degenerative joint disease, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. 8Adapted

The method detects and determines whether diagnostically or prognostically significant levels of YKL-40 protein and/or YKL-40 peptide are present in a biological sample. The method can be used, for example, to identify the presence of inflammatory or degenerative joint disease or degeneration of connective tissue in organs. Serum YKL-40 levels as detected and quantified by the inventive method are also suggestive of the prognosis for the length of survival in breast cancer patients following recurrence and/or metastasis of their cancers. The figure shows the elution position of substantially pure serum YKL-40 on a gel filtration column. Excerpt(s): The invention relates to the identification of a circulating protein associated with extracellular fiber matrix metabolism in mammalian connective tissues. More specifically, it is directed to assays for the detection and quantitation of molecules and fragments of YKL-40, a protein associated with connective tissue metabolism in mammals. It also involves correlating serum levels of YKL-40 in a mammal to the presence and status of diseases in which matrix metabolism plays a role, such as joint disorders and the metastasis of certain tumors. The extracellular matrix of mammalian connective tissues (such as articular cartilage of joints and vascular wall tissue of the vascular and lymphatic system) provides strength to, and (to varying degrees) a barrier to the migration of cells from, the tissue. In certain disease processes, however, the matrix is degraded by hydrolytic enzymes. As the matrix degrades, the integrity of the tissue is impaired, which may allow tissue cells, by-products and other residues of the matrix metabolism to escape into bodily fluids and/or lymphatic or vascular circulation. Detection of these molecules and cells can, in certain instances, provide information regarding the biochemical characteristics of the extracellular matrix, including how it is synthesized and how it is lost. Also, where a particular molecule that is produced and/or secreted during abnormal matrix metabolism is closely related to a disease process, quantitation of that molecule in the patient's body fluids and/or tissues can help clinicians monitor the progress of the disease. Human joint cartilage is known to contain several different types of proteins and proteoglycans, a few of which are present only in cartilage. These matrix constituents are released from cartilage tissue as it degrades during the course of certain joint diseases. The quantity of released matrix constituents (including fragments thereof and related macromolecules) present in a particular fluid or tissue may correlate with the intensity of the disease. Conversely, where the damage to the cartilage is reversible (as in secondary reactive arthritis caused by infection of the joint tissue), a reduction in levels of previously measured released matrix constituents may correlate with the degree of remission of the disease.

Compositions to suppress gastric bleeding in indomethacin and phenylbutazone therapy Inventor(s): Alphin; Reevis Stancil (Richmond, VA), Droppleman; David Andrew (Richmond, VA) Assignee(s): A. H. Robins Company, Incorporated (Richmond, VA) Patent Number: 3,993,767 Date filed: November 18, 1975 Abstract: Methods of treating symptomatic conditions of inflammation due to chronic and acute rheumatic and degenerative joint disease with a combination of indomethacin or phenylbutazone and a phenoxymethyl-2-oxazolidinone resulting in beneficial reduction in side effects of ulceration and bleeding in the lower intestinal tract normally associated with indomethacin and phenylbutazone and compositions containing the combination are disclosed. Excerpt(s): This invention relates to novel methods, combinations, and compositions for controlling inflammation in the relief of symptomatic, chronic and acute rheumatic conditions. More particularly, the invention relates to combinations and compositions of indomethacin or phenylbutazone and phenoxymethyl-2-oxazolidinones and methods of using them to ameliorate the undesirable side effects of indomethacin or phenylbutazone in the gastrointestinal tract. Indomethacin and phenylbutazone are widely used for the therapy of inflammatory conditions associated with rheumatic diseases and/or arthritis. However, certain undesirable side effects are associated with the use of indomethacin and phenylbutazone in the gastrointestinal region, among which side effects are bleeding, ulceration, perforation of the intestines and occasionally death. The need to overcome the irritation, particularly in the lower gastrointestinal tract, caused by indomethacin and phenylbutazone is a matter of urgent concern, inasmuch as the walls of the intestine in the lower region are relatively thin and perforation may occur suddenly and without warning. The method of the present invention, having suitably overcome, by remedial action, the severe manifestation of ulceration and perforation in the lower GI tract normally associated with indomethacin and phenylbutazone therapy, is highly suited to the treatment of the symptomatic inflammatory effect in mammals and humans of diseases such as gouty arthritis, bursitis, rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis and the like. Indicative of the state of the art have been attempts to find combinations which would allow administration of indomethacin or phenylbutazone for their full therapeutic effect as anti-inflammatory drugs. Certain steroids such as spirolactone have shown protection against intestinal ulcers caused by indomethacin in rats [Can. J. Physiol. Pharmacol. 1969, 47 (12) 981-3]. Coprecipitates of lignosulfonate or tannic acid with indomethacin or phenylbutazone have shown reduced irritation on the stomach tissue of cats. [C. A. 78, P102009n and C. A. 79, P9873]. Pro-Bathine which is ammonium (2-hydroxyethyl)diisopropylmethylbromide, xanthine-9-carboxylate has shown reduced ulceration caused by indomethacin in the rat stomach [Arch. Int. Pharmacodyn. 191, 370-377 (1971)]. Web site: http://www.delphion.com/details?pn=US03993767__

Method of treating degenerative joint disease by injection of meth(acrylamide) (co)polymers Inventor(s): Chylinski; Victoria S. (11 Peghouse Rise, Slad Road, Stroud, Glos., GB2), Trager; Seymour F. (14 Sherwood Dr., Plainview, NY 11803) Assignee(s): none reported Patent Number: 4,828,828 Date filed: July 28, 1987 Abstract: A method for the treatment of degenerative joint disease in a mammal suffering therefrom which includes administration by injection of an effective amount of a pharmaceutical composition into the arthritically afflicted joints of the mammal thereby lubricating and cushioning the joints. The composition includes acrylamide or methacrylamide polymers or copolymers thereof having a molecular weight from about 1 to about 15 million and a pharmaceutically acceptable diluent. Excerpt(s): Mammalian joints typically contain a small amount of synovial fluid which lubricates and moistens the joint surfaces to protect the joint against trauma, injury and degeneration. Some specific synovial fluid functions are to lubricate the joint surfaces, to absorb shocks to the joints, to bind acid and, possibly, to nourish some of the structural components of the joints. The synovial fluid is produced in the body by specialized cells, and the impairment of the fluid, i.e. decreased viscosity of the fluid due to the presence of degenerate cartilage products therein, is the principal source of the pain associated with degenerative joint diseases. As a result, various modes of intra-articular treatment of arthritis have been proposed. Commercially available compositions including corticosteroids such as triamcinoline, prednisolone and hydrocortisone acetate are now in use in arthritis treatment. However, these compositions are difficult to use due to difficulties in dosage determination. Also, a number of adverse reactions have been observed in intra-articular steroid therapy. Consequently, corticosteroid treatments have fallen into relative disuse. The use of hyaluronic acid has also been proposed for arthritis treatment. Hyaluronic acid appears to lubricate only the soft tissues of the joint which are not subject to heavy loading. Again, adverse side effects stemming from the treatment have been reported in some patients. Moreover, patients with clinical histories of local adverse reactions to the acid treatment appear susceptible to severe permanent joint damage.

Use of N-acetylglucosamine for the therapy of degenerative joint disease and related diseases Inventor(s): Speck; Ulrich (Benediktinerstrasse 50, D-1000 Berlin 28, DE) Assignee(s): none reported Patent Number: 4,870,061 Date filed: January 26, 1989 Abstract: The invention refers to the use of N-acetylglucosamine for the therapy of degenerative diseases of the joints and of the connective and the supporting tissues as well as for the therapy of related diseases, wherein the N-acetylglucosamine is administered to the body through buccal absorption.

Patents 49

Excerpt(s): The present invention refers to the use of N-acetylglucosamine for the therapy of degenerative diseases of the joints and of the connective and the supporting tissues as well as for the therapy of related diseases. Moreover, the invention comprises the use of N-acetylglucosamine for the production of drugs for corresponding therapies. Degenerative diseases of the joints (arthrosis) are widespread with human beings as well as with animals of middle and higher age. They are a frequent reason for poor general condition and limited ability to work. One main reason for these diseases is the destruction of glucosaminoglycanes (GAG) which are an essential component of the cartilage substances and of other flexible elements as well as a contributor to the lubrication of the joints. The therapy of these painful, partly inflammatory conditions often only takes place symptomatically with the aid of non-steroidal anti-inflammatory drugs such as, for instance, indomethacin, or even corticoids. Both groups of therapeuticals cause severe side effects and should therefore be used as little as possible. Moreover, the application of non-steroidal anti-inflammatory drugs and corticoids entails the danger of further shifting the metabolism of the GAGs in the direction of accelerated degradation. Thus, the advantages of momentary relief of the symptoms of the disease, such as pain and immobility of the joints, is--besides other risks--connected with the danger of an acceleration in the degenerative processes which cause the underlying disease.

e.g., for post surgical joint lavage or treatment and/or prevention of inflammatory arthritis, osteoarthritis (OA) and/or degenerative joint disease (DJD). Diarthrodial or synovial joints allow movement and transfer of load between bones. These two critical functions play a major role in athletic performance and disease or injury of these joints, in turn, has a major impact on athletic performance in man and in animals. For example, one of the most important causes of lameness among equine athletes is primary joint disease of the diathrodial or synovial joints. In the past 25 years much knowledge has been gained regarding the treatment and/or prevention of disease processes affecting synovial joints and, in particular, in the understanding of disease and trauma of articular cartilage (see, Mcllwraith & Trotter, "JOINT DISEASE IN THE HORSE", W. B. Saunders, 1996 (ISBN 0-7216-5135-6)). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Surface electrical stimulation for increasing the quality and quantity of synovial fluid in joints Inventor(s): Carroll, William J.; (Sedro Woolley, WA), Terrell, Richard M.; (Vancouver, WA) Correspondence: Blank Rome Llp; 600 New Hampshire Avenue, N.W.; Washington; DC; 20037; US Patent Application Number: 20040054379 Date filed: September 11, 2003 Abstract: An electro-medical device and method for improving synovial fluid at a body segment having a joint by applying surface electrical stimulation using surface skin electrodes to the body segment. The electrical stimulation to the body segment and joint may be continuous or in a sequencing pattern. When the electrical stimulation uses a sequencing pattern, it mimics normal electrical sequencing of surrounding muscle of the joint during normal functioning activity. Surface electrical stimulation improves synovial fluid of the body segment and joint and ameliorates degenerative joint disease and osteoarthritis. Excerpt(s): Surface Electrical Stimulation (SES) has a beneficial effect on the production and quality of the synovium and the resultant synovial fluid. Electrical stimulation increases blood flow to stimulated areas (U.S. Pat. No. 6,393,328). However, the effect of SES on synovial fluid output and quality and on cartilage and joint deterioration has not been demonstrated or quantified. There is a need to demonstrate that SES has a beneficial effect on decreasing the progressive process of joint deterioration. Thus, there is a unaddressed need in the industry to demonstrate the beneficial effects of SES for the treatment and ameloriation of osteoarthritis and degenerative joint disease of, but not limited to, the hips, knees, ankles, toes, back, neck, and shoulders. Embodiments of the present invention provide an electro-medical device and method for improving synovial fluid at a body segment having a joint by applying surface electrical stimulation, using surface skin electrodes, to the body segment. The present invention utilizes surface electrical stimulation via surface skin electrodes to pass various types of current across the skin, or transcutaneously, wherein the surface skin electrodes are placed on the surface of the skin. Examples of this type of stimulation include, but are not limited to, Transcutaneous Electrical Never Stimulation (TENS), neuromuscular Electrical Stimulation (NMES), interferential stimulation, diadynamic stimulation, High Volt Galvanic Stimulation (HVGS), Electro-Magnetic and Pulsed Electro-Magnetic Field stimulation (EMF) and (PEMF) and, micro-current stimulation. Those types of surface

52


electrical stimulation can be applied in a continuous manner or they may be applied in patterns of stimulation that mimic the natural functioning of the affected joint. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Contact publisher directly for current price in U.S. Dollars. ISBN: 8716106377. Summary: This chapter on degenerative joint disease (osteoarthrosis and osteoarthritis, or OA) is from a comprehensive textbook that addresses temporomandibular joint disorders (TMD) and masticatory muscle disorders. Topics include definitions and general features, the prevalence of OA, etiology, pathogenesis, diagnostic considerations, and treatment. OA is defined as a primarily non-inflammatory pattern of reaction of movable joints to injury. The disease process is characterized by deterioration

54


and abrasion of articular cartilage and soft tissue surfaces, and the occurrence of thickening and remodelling of the underlying bone and formation of marginal spurs and subarticular 'cysts.' The temporomandibular (TMJ) is one joint that can be affected by OA. The authors note that non-drug treatment strives to reduce joint overload so that healing can occur; consequently, rest and exercise are regarded as an important part of a self care strategy. Reversible dental interventions such as appliance therapy or restoration of posterior occlusal support may produce long-range benefits, although this has not yet been conclusively shown in clinical trials. The clinical long-term prognosis of TMJ OA is usually extremely favorable in spite of regularly observed severe radiographic changes. 5 figures. 2 tables. 40 references. (AA-M).

Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.

Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •

CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.

•

Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.

18 Adapted 19

from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.

The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on degenerative joint disease can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.

Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to degenerative joint disease. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to degenerative joint disease. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “degenerative joint disease”:

Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on degenerative joint disease. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

Contact: Available from Fibromyalgia Association of Greater Washington (FMAGW). 13203 Valley Drive, Woodbridge, VA 22191. (703) 790-2324. PRICE: Single copy free. Summary: This brochure outlines the relationship of temporomandibular joint dysfunction (TMD) and fibromylagia syndrome. The brochure stresses that TMD is a complex problem even for the otherwise healthy patient, but when it is combined with the multiple symptoms of a patient with fibromyalgia syndrome, it becomes difficult to diagnose and treat effectively without a team approach involving multiple disciplines. Because of the intricate neural pathways in and around the TM join and reflex referral arcs to far distant areas, the picture of TMD becomes complex when it is combined with the symptoms of fibromyalgia. The causes of TMD are varied and may include trauma, loss of teeth, improperly fitted dental appliances, improper orthodontic therapy, a variety of degenerative joint disease, growth and developmental problems, tumors, and bruxism (toothgrinding). Treatment ranges from simple appliance therapy along with warm, moist compresses, a soft diet and anti-inflammatory medication, to a multidisciplinary approach involving special x-rays, computerized measurement of jaw and muscle relationships and function, and specialized appliances along with physical therapy, and rheumatological evaluation. The brochure concludes that a dentist specializing in TMD or MPD (myofascial pain dysfunction) is necessary to determine the most appropriate therapy for each patient based on the presentation, severity, and dimensions of his or her symptoms and the nature of the problems present. The National Guideline Clearinghouse™ The National Guideline Clearinghouse™ offers hundreds of evidence-based clinical practice guidelines published in the United States and other countries.

The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to degenerative joint disease. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html.

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to degenerative joint disease. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with degenerative joint disease. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about degenerative joint disease. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “degenerative joint disease” (or a synonym), and you will receive information on all relevant organizations listed in the database.

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.

Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21

Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.

Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

DEGENERATIVE JOINT DISEASE DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Aberrant: Wandering or deviating from the usual or normal course. [EU] Abrasion: 1. The wearing away of a substance or structure (such as the skin or the teeth) through some unusual or abnormal mechanical process. 2. An area of body surface denuded of skin or mucous membrane by some unusual or abnormal mechanical process. [EU] Accommodation: Adjustment, especially that of the eye for various distances. [EU] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Acetylglucosamine: The N-acetyl derivative of glucosamine. [NIH] Acrylamide: A colorless, odorless, highly water soluble vinyl monomer formed from the hydration of acrylonitrile. It is primarily used in research laboratories for electrophoresis, chromatography, and electron microscopy and in the sewage and wastewater treatment industries. [NIH] Acrylonitrile: A highly poisonous compound used widely in the manufacture of plastics, adhesives and synthetic rubber. [NIH] Adrenal Cortex: The outer layer of the adrenal gland. It secretes mineralocorticoids, androgens, and glucocorticoids. [NIH] Adverse Effect: An unwanted side effect of treatment. [NIH] Aerobic: In biochemistry, reactions that need oxygen to happen or happen when oxygen is present.

The 20 a-amino acids listed in the accompanying table are the amino acids from which proteins are synthesized by formation of peptide bonds during ribosomal translation of messenger RNA; all except glycine, which is not optically active, have the L configuration. Other amino acids occurring in proteins, such as hydroxyproline in collagen, are formed by posttranslational enzymatic modification of amino acids residues in polypeptide chains. There are also several important amino acids, such as the neurotransmitter y-aminobutyric acid, that have no relation to proteins. Abbreviated AA. [EU] Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. [NIH] Anaesthesia: Loss of feeling or sensation.

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors. [EU] Complementary and alternative medicine: CAM. Forms of treatment that are used in addition to (complementary) or instead of (alternative) standard treatments. These practices are not considered standard medical approaches. CAM includes dietary supplements, megadose vitamins, herbal preparations, special teas, massage therapy, magnet therapy, spiritual healing, and meditation.
