COLUMBIA, Mo. - Osteoarthritis is commonly diagnosed in the late and irreversible stages, when treatment can only be expected to decrease pain and slow progression of disease. Because osteoarthritis is a widespread problem in dogs, horses and humans, doctors and veterinarians need a precise way to diagnose the disease early and accurately. Now, University of Missouri researchers are investigating potential biomarkers in dogs for early diagnosis of osteoarthritis, which could help identify patients at increased risk of developing osteoarthritis.. "By developing methods for earlier diagnosis of osteoarthritis, prevention or even curative treatment strategies to manage the disease become more realistic," said James Cook, professor of veterinary medicine and surgery, and the William & Kathryn Allen Distinguished Professor in Orthopedic Surgery. ...

Management of osteoarthritis pain remains a huge challenge in the clinic with millions of arthritis patients living with chronic disability. Limitations to current pharmacological treatment strategies include a lack of therapeutic efficacy and potentially hazardous side-effects. Therefore, there is a pressing need to understand the underlying mechanisms that evoke OA pain and to develop new, more effective analgesics. One intuitive approach would be to attenuate pathological OA-induced pain by selectively blocking joint nociceptors while preserving other desirable physiological functions of the nerve. Intra-articular injection of non-selective sodium channel blockers has been shown to be effective for the treatment of OA pain [29] while intravenous administration of these agents can produce long lasting pain relief in both animal models [30] and in patients with intractable neuropathic pain [31]. The clear disadvantages of using non-selective sodium channel blockers locally are complete loss ...

*  PKCδ null mutations in a mouse model of osteoarthritis alter osteoarthritic pain independently of joint pathology by augmenting...

The mechanism by which OA develops from an asymptomatic condition to a painful disease has been a critical gap in our knowledge. The complementarity between our results from an experimental OA animal model and our human subject findings has significant ramifications for resolving a long-standing clinical discrepancy of the lack of correlation between histological damage and the degree of joint pain. We now show that the PKCδ is a key inhibitor of NGF/TrkA axis signalling and sensory nerve sprouting in synovial tissues and DRGs, and thus alleviates OA hyperalgesia. This beneficial function of PKCδ in reducing synovial innervation is diametrically opposed to the inflammation-responsive catabolic function of PKCδ in articular chondrocytes that mediates cartilage destruction. We postulate that the degree of pain in OA is directly attributable to changes in PKCδ signalling in sensory neurons rather than to joint pathology per se. Therefore, understanding the neural mechanisms by which PKCδ ...

(1/3950) Overexpression of human homologs of the bacterial DnaJ chaperone in the synovial tissue of patients with rheumatoid arthritis.

OBJECTIVE: To study the expression of the chaperone family of J proteins in the synovial tissue of patients with rheumatoid arthritis (RA) or osteoarthritis. METHODS: Rabbit antibodies specific for a synthetic peptide (pHSJ1: EAYEVLSDKHKREIYD), representing the most conserved part of all J domains thus far identified--among them the Drosophila tumor suppressor Tid56--were used in immunohistochemical analyses of frozen sections of synovial tissue and immunoblotting of protein extracts of adherent synovial cells. IgG specific for Tid56 was also used. RESULTS: Both antisera predominantly and intensely stained synovial lining cells from RA patients; other cells did not stain or stained only faintly. In immunoblots, anti-pHSJ1 specifically detected several bands with molecular weights of >74 kd (type I), 57-64 kd (type II), 41-48 kd (type III), and < or =36 kd (type IV). The strongest band detected in RA adherent synovial cells was the type II band, whereas in a B cell line, a type I band was prominent. CONCLUSION: Several potentially new members of the J family are described. The type II band represents the human homolog of the Drosophila Tid56 protein and is strongly expressed in RA synovial tissue.  (+info)

(2/3950) Establishment and characterization of nurse cell-like stromal cell lines from synovial tissues of patients with rheumatoid arthritis.

OBJECTIVE: To investigate the features of synovial stromal cells established from patients with rheumatoid arthritis (RA), and to define these cells as nurse cells. METHODS: Synovial nurse-like stromal cell lines (RA-SNCs) were established from patients with RA. These cell lines were examined for morphology, pseudoemperipolesis activity, cell surface markers, and cytokine production. The interaction between these RA-SNCs and a synovial tissue B cell clone was also examined. RESULTS: RA-SNCs had nurse cell activity. They spontaneously produced interleukin-6 (IL-6), IL-8, granulocyte colony-stimulating factor, and granulocyte-macrophage colony-stimulating factor. Furthermore, they produced IL-1beta and tumor necrosis factor alpha and expressed higher levels of the other cytokines after coculture with the B cell clone. Proliferation and Ig production by the B cell clone were dependent on direct contact with RA-SNCs. CONCLUSION: These results indicate that the RA-SNCs were nurse cells. The findings suggest that RA-SNCs may play an important role in the pathogenesis of RA by producing large amounts of cytokines and maintaining infiltrating lymphocytes.  (+info)

(4/3950) Prevalence of generalised osteoarthritis in patients with advanced hip and knee osteoarthritis: the Ulm Osteoarthritis Study.

OBJECTIVES: Different prevalences of generalised osteoarthritis (GOA) in patients with knee and hip OA have been reported. The aim of this investigation was to evaluate radiographic and clinical patterns of disease in a hospital based population of patient subgroups with advanced hip and knee OA and to compare the prevalence of GOA in patients with hip or knee OA, taking potential confounding factors into account. METHODS: 420 patients with hip OA and 389 patients with knee OA scheduled for unilateral total joint replacement in four hospitals underwent radiographic analysis of ipsilateral and contralateral hip or knee joint and both hands in addition to a standardised interview and clinical examination. According to the severity of radiographic changes in the contralateral joints (using Kellgren-Lawrence > or = grade 2 as case definition) participants were classified as having either unilateral or bilateral OA. If radiographic changes of two joint groups of the hands (first carpometacarpal joint and proximal/distal interphalangeal joints defined as two separate joint groups) were present, patients were categorised as having GOA. RESULTS: Patients with hip OA were younger (mean age 60.4 years) and less likely to be female (52.4%) than patients with knee OA (66.3 years and 72.5% respectively). Intensity of pain and functional impairment at hospital admission was similar in both groups, while patients with knee OA had a longer symptom duration (median 10 years) compared with patients with hip OA (5 years). In 41.7% of patients with hip OA and 33.4% of patients with knee OA an underlying pathological condition could be observed in the replaced joint, which allowed a classification as secondary OA. Some 82.1% of patients with hip and 87.4% of patients with knee OA had radiographic changes in their contralateral joints (bilateral disease). The prevalence of GOA increased with age and was higher in female patients. GOA was observed more often in patients with knee OA than in patients with hip OA (34.9% versus 19.3%; OR = 2.24; 95% CI: 1.56, 3.21). Adjustment for the different age and sex distribution in both patient groups, however, takes away most of the difference (OR = 1.32; 95% CI: 0.89, 1.96). CONCLUSION: The crude results confirm previous reports as well as the clinical impression of GOA being more prevalent in patients with advanced knee OA than in patients with advanced hip OA. However, these different patterns might be attributed to a large part to a different distribution of age and sex in these hospital based populations.  (+info)

(5/3950) Nuclear factor-kappa B activity in T cells from patients with rheumatic diseases: a preliminary report.

OBJECTIVE: The NF-kappa B/Rel family of transcription factors regulates the expression of many genes involved in the immune or inflammatory response at the transcriptional level. The aim of this study was to determine whether distinctive patterns of NF-kappa B activation are seen in different forms of joint disease. METHODS: The DNA binding activity of these nucleoproteins was examined in purified synovial and peripheral T cells from patients with various chronic rheumatic diseases (12: four with rheumatoid arthritis; five with spondyloarthropathies; and three with osteoarthritis). RESULTS: Electrophoretic mobility shift assays disclosed two specific complexes bound to a NF-kappa B specific 32P-labelled oligonucleotide in nucleoproteins extracted from purified T cells isolated from synovial fluid and peripheral blood of patients with rheumatoid arthritis. The complexes consisted of p50/p50 homodimers and p50/p65 heterodimers. Increased NF-kappa B binding to DNA in synovial T cells was observed relative to peripheral T cells. In non-rheumatoid arthritis, binding of NF-kappa B in synovial T cells was exclusively mediated by p50/p50 homodimers. CONCLUSION: Overall, the results suggest that NF-kappa B may play a central part in the activation of infiltrating T cells in chronic rheumatoid arthritis. The activation of this nuclear factor is qualitatively different in rheumatoid synovial T cells to that in other forms of non-rheumatoid arthritis (for example, osteoarthritis, spondyloarthropathies).  (+info)

(6/3950) Effects of joint lavage and steroid injection in patients with osteoarthritis of the knee: results of a multicenter, randomized, controlled trial.

OBJECTIVE: To evaluate the efficacy of joint lavage and intraarticular steroid injection, alone and in combination, in the treatment of patients with symptomatic knee osteoarthritis (OA). METHODS: Ninety-eight patients with painful tibiofemoral OA were enrolled in a prospective, randomized, controlled, 2 x 2 factorial-design trial of 6 months' duration. The 4 treatment groups consisted of 1) intraarticular placebo (1.5 ml of 0.9% normal saline), 2) intraarticular corticosteroids (3.75 mg of cortivazol in 1.5 ml), 3) joint lavage and intraarticular placebo, and 4) joint lavage and intraarticular corticosteroid. Outcome measures evaluated at baseline, week 1, week 4, week 12, and week 24 included severity of pain (100-mm visual analog scale [VAS]), global status (100-mm VAS), and Lequesne's functional index. RESULTS: No interaction between steroid injection and joint lavage was demonstrated. Patients who had undergone joint lavage had significantly improved pain VAS scores at week 24 (P = 0.020). In contrast, corticosteroid injection had no long-term effect (P = 0.313); corticosteroid injection was associated with a decrease in pain only at week 1 (P = 0.003) and week 4 (P = 0.020). After week 4, Lequesne's functional index was not significantly improved regardless of the assigned treatment. CONCLUSION: Compared with placebo, both treatments significantly relieved pain but did not improve functional impairment. The effects of the 2 treatments were additive. Cortivazol provided short-term relief of pain (up to week 4). The effects of joint lavage persisted up to week 24.  (+info)

(7/3950) The associations of bone mineral density and bone turnover markers with osteoarthritis of the hand and knee in pre- and perimenopausal women.

OBJECTIVE: To determine whether Caucasian women ages 28-48 years with newly defined osteoarthritis (OA) would have greater bone mineral density (BMD) and less bone turnover over time than would women without OA. METHODS: Data were derived from the longitudinal Michigan Bone Health Study. Period prevalence and 3-year incidence of OA were based on radiographs of the dominant hand and both knees, scored with the Kellgren/Lawrence (K/L) scale. OA scores were related to BMD, which was measured by dual-energy x-ray absorptiometry, and to serum osteocalcin levels, which were measured by radioimmunoassay. RESULTS: The period prevalence of OA (K/L grade > or =2 in the knees or the dominant hand) was 15.3% (92 of 601), with 8.7% for the knees and 6.7% for the hand. The 3-year incidence of knee OA was 1.9% (9 of 482) and of hand OA was 3.3% (16 of 482). Women with incident knee OA had greater average BMD (z-scores 0.3-0.8 higher for the 3 BMD sites) than women without knee OA (P < 0.04 at the femoral neck). Women with incident knee OA had less change in their average BMD z-scores over the 3-year study period. Average BMD z-scores for women with prevalent knee OA were greater (0.4-0.7 higher) than for women without knee OA (P < 0.002 at all sites). There was no difference in average BMD z-scores or their change in women with and without hand OA. Average serum osteocalcin levels were lower in incident cases of hand OA (>60%; P = 0.02) or knee OA (20%; P not significant). The average change in absolute serum osteocalcin levels was not as great in women with incident hand OA or knee OA as in women without OA (P < 0.02 and P < 0.05, respectively). CONCLUSION: Women with radiographically defined knee OA have greater BMD than do women without knee OA and are less likely to lose that higher level of BMD. There was less bone turnover among women with hand OA and/or knee OA. These findings suggest that bone-forming cells might show a differential response in OA of the hand and knee, and may suggest a different pathogenesis of hand OA and knee OA.  (+info)

(8/3950) Tumor necrosis factor alpha regulation of the FAS-mediated apoptosis-signaling pathway in synovial cells.

OBJECTIVE: Fas-mediated apoptosis is observed in synoviocytes of patients with rheumatoid arthritis (RA), but not in those of patients with osteoarthritis (OA). The present study was conducted to elucidate the mechanisms that initiate induction of Fas-mediated apoptosis in RA synoviocytes. METHODS: Cultured OA synoviocytes, which are insensitive to Fas-mediated apoptosis in spite of Fas antigen expression, were used in these experiments. Synovial cell proliferation and cytotoxicity studies were performed using MTS and lactate dehydrogenase release assays. Surface expression of Fas antigen was analyzed by flow cytometry. The expression and function of apoptosis-signaling molecules, such as caspase 8 and caspase 3, were examined by immunoblot analysis. RESULTS: Tumor necrosis factor alpha (TNFalpha) induced proliferation of cultured OA synoviocytes. Fas ligation with anti-Fas monoclonal antibody (mAb) resulted in cytotoxic activity against cultured OA synoviocytes that had been pretreated with TNFalpha for 5 days, but not those pretreated for 2 days. In contrast, anti-Fas mAb did not show a cytotoxic effect against untreated cultured OA synoviocytes. A gradual up-regulation of caspase 8 and caspase 3, which played a role in the caspase cascade for Fas-mediated apoptosis, was observed in TNFalpha-treated cultured OA synoviocytes. In addition, Fas ligation to TNFalpha-treated cultured OA synoviocytes induced activation of caspase 8 and caspase 3, with subsequent cleavage of poly(ADP-ribose) polymerase (PARP), a substrate of activated caspase 3. More importantly, Z-IETD-FMK, a caspase 8 inhibitor, and Ac-DEVD-CHO, a caspase 3 inhibitor, almost completely inhibited Fas-mediated apoptosis of TNFalpha-treated cultured OA synoviocytes, whereas Ac-YVAD-CHO, a caspase 1 inhibitor, did not. CONCLUSION: Our results clearly demonstrate that TNFalpha stimulates synovial cells to proliferate as well as sensitizes the cells for Fas-mediated apoptosis, at least in part by up-regulation and activation of caspase 8 and caspase 3. These findings suggest that TNFalpha may be one of the factors providing sensitization of synovial cells to Fas-mediated apoptosis in RA.  (+info)
