[Experimental rationale and clinical evaluation of perichondroplasty used in surgery for tuberculosis and nonspecific joint diseases].

Experiments on 77 rabbits studied the specific features of chondrogenesis during different grafting modifications for the perichondrium. The latter was found to have a high chondroplastic potential. The factors predisposing to cartilaginification and inhibiting this process were identified. Experimental positive results of perichondrial arthroplasty, in tuberculous arthritis as well, were achieved. By taking into account the experimental data, original methods for reparative operations used in patients with tuberculosis and nonspecific diseases of the joints were developed in the clinical setting. Their use in 12 patients yielded positive results, suggesting that the above methods are promising and their further study is advisable.

Serum IgM rheumatoid factor by enzyme-linked immunosorbent assay (ELISA) delineates a subset of patients with deforming joint disease in seronegative juvenile rheumatoid arthritis.

Using human IgG as an antigen in an enzyme-linked immunosorbent assay (ELISA), we looked for the presence of IgM rheumatoid factor (RF) in the sera of 74 children with juvenile rheumatoid arthritis (JRA). Nine children had RF detectable by both latex agglutination and ELISA. Forty-five percent (26 of 65) of the children who were seronegative by latex agglutination were found to be positive for IgM RF by ELISA. The prevalence of IgM RF was higher in patients with polyarticular onset disease (57.4%) than in those with pauciarticular onset (38.5%) or systemic onset (27.2%) disease. The prevalence of RF was higher in sera from patients with deforming joint disease than those without deformities (P < 0.01).

Antisense strategies in degenerative joint diseases: sense or nonsense?

Oligodeoxynucleotides, ribozymes, and RNA interference make part of the antisense strategy, a new tool proposed to conquer cancer, viral infections, as well as cardiovascular and rheumatic diseases. The silencing effect of antisense strategies is both highly specific and potent - and only requires that the sequence of the target RNA is known. However, so far neither RNAi nor ribozymes have been approved for clinical use and only a single antisense agent is on the market. In the context of degenerative joint diseases, experimental data in the field of antisense strategies are still rare. Several studies from rheumatoid arthritis (RA), an inflammatory condition that leads to the progressive destruction of cartilage and bone within affected joints, however revealed promising results and taught us important lessons that might also be useful in therapeutic approaches for osteoarthritis (OA). To introduce these therapies in clinical practice, however, several hurdles still have to be overcome.

[Therapy of degenerative joint diseases of a rheumatic nature. Effectiveness of naproxen at a daily dosage of 500 mg].

40 patients with degenerative joint diseases were treated with a new application form of naproxen (Proxen 500 film-coated tablets). The patients received one tablet daily in the evening for a period of 4 weeks. The therapeutic efficacy was demonstrated clinically on swelling of the joints, reduction of mobility, pressure pain, muscular stiffness and by improvement of pain symptoms: pain during day and night, pain at rest, movement pain. During therapy 75% of the cases showed marked improvement of the subjective and objective symptoms. The once daily application in the evening did not only influence favourable nocturnal and rest pain, but also reduced diurnal and movement pain significantly. In accordance with these findings 23 hours after application in the evening nearly constant serum levels of naproxen were found for the whole duration of treatment. The fast release of the active substance from the film-coated tablets leads to a rapid onset of the analgesic activity.

Comparison of HIG scintigraphy and bloodpool scintigraphy using HDP in arthritic joint disease.

AIM: Because of a similar tracer accumulation, we assumed to get the same information about synovitis in arthritic joint disease with HIG scintigraphy and bloodpool scintigraphy using HDP. Therefore, we compared retrospectively 23 patients. METHODS: In HIG scintigraphy, synovitis was diagnosed according to increasing activity from early to late image. In bloodpool scintigraphy according to an increased activity in comparison to the surrounding tissues. RESULTS: In 694 joints comparison of both scintigraphic modalities was possible, resulting in a 2 x 2 kappa coefficient of 0.93 or 0.97 by using late-phase bone scintigraphy as an anatomical marker. For intra- and interobserver agreement, 2 x 2 kappa coefficients of 0.93 and 0.88 in HIG scintigraphy, respectively 0.96 and 0.90 in blood-pool scintigraphy were calculated. CONCLUSION: This study shows an excellent agreement in the visualization of synovitis by HIG and bloodpool scintigraphy. Because of its higher objectivity and lower cost, investigation of synovitis should be performed by bloodpool scintigraphy.

Arthroscopic treatment of the hip in early and midstage degenerative joint disease.

The purpose of this study was to present the technique of arthroscopic capsule release in patients with early and midstage degenerative joint disease of the hip. In 22 patients we performed an arthroscopic capsular release of the hip joint capsule with simultaneous synovectomy and percutaneous drilling of areas of bone edema. The age of the patient ranged from 28 to 65 years (mean 52 years). There were 14 male and 8 female patients. All patients had suffered from a significant reduction of quality of life. In 15 of the 22 patients hip arthroplasty was already indicated in another institution. The preoperative Harris hip Score of 12 patients was below 69 points, 8 patients had a score between 70 and 79 points and 2 patients had a score between 80 and 89 points. At the time of follow-up (mean 26 months after surgery) 1 patient scored below 69 points, 3 patients scored between 70 and 79 points in the Harris hip score. Two patients scored between 80 and 89 points and 16 patients reached a score between 90 and 100 points. Subjective and objective 18 of 22 patients showed clinical relevant improvement. There was no complication in this series. Four patients underwent hip arthroplasty between 6 months and 2 years after the arthroscopic procedure. Minimal invasive arthroscopic treatments seem to decrease the subjective and objective complaints in early and midstage degenerative arthritis of the hip.

Articular cartilage proteoglycan metabolism in avian degenerative joint disease: effects of strain selection and body weight.

The effects of strain selection and body weight on proteoglycan metabolism and the onset of degenerative joint disease (DJD) were investigated in avian articular cartilage. Samples from the hock joint (proximal tarsometatarsus, PTM; distal tibiotarsus, DTT) of rapidly growing broiler fowl, fed either ad libitum or on a restricted-diet, were compared with those from a slow growing, light and non-selected strain (J-line). Synthesis and degradation of proteoglycans were investigated by radioactive pulse-chase studies, determination of total sulphated glycosaminoglycans and electrophoretic analysis. By gross morphology, degenerative changes in articular cartilage occurred solely in the DTT from ad libitum-fed broiler fowl, after 13 weeks. Differences in proteoglycan metabolism were also observed, most markedly in the DTT, where the rate of proteoglycan synthesis in the ad libitum-fed group was less than in age-matched J-line cartilage, and the proportions of both newly synthesised and resident proteoglycans released into the culture medium were greater. Results with the feed-restricted group were intermediate between ad libitum-fed and J-line. Electrophoretic analysis of proteoglycans in the culture media showed evidence of degradation solely in the ad libitum-fed group, with earliest onset in the DTT. The results indicate that proteoglycan metabolism in avian articular cartilage is similar to that in mammalian cartilage during the development of DJD, and that the onset of cartilage degeneration is linked with excessive load bearing.

Total incidence and distribution of inflammatory joint diseases in a defined population: results from the Kuopio 2000 arthritis survey.

OBJECTIVE: To study the incidence of inflammatory joint diseases in a defined population in Finland. METHODS: We collected data for the year 2000 on a population of 87,000 inhabitants of Kuopio, Finland, of whom 20% were < 16 years of age. Information about the study was given through a local newspaper, and subjects attended one health center and 2 local hospitals for study. Inclusion criteria were that subjects have at least one peripheral joint with synovitis or signs of inflammation in sacroiliac, glenohumeral, or hip joints on the first visit. Incidence rates were calculated according to the diagnosis on the first visit, except for children, for whom diagnoses were established after 3 months' followup. RESULTS: A total of 188 adult incident cases (138 women, 50 men) and 11 children (8 girls, 3 boys) satisfied the inclusion criteria. The incidence of all arthritides was 230/100,000 (95% confidence interval 198.9-263.9) for the whole population; 271/100,000 (95% CI 233.7-312.7) for adults and 64/100,000 (95% CI 31.7-113.8) for children. Among adults the annual incidence of rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), reactive arthritis (ReA), other spondyloarthropathies (SpA), connective tissue disease (CTD), crystalline arthritis, viral arthritis, and undifferentiated arthritis were 36, 7, 23, 10, 13, 9, 19, 7, and 149/100,000, respectively. The mean age at diagnosis was 49.4 +/- 16.3 years for all cases of arthritis among adults, about the same for both women and men. The mean age at diagnosis was 59.7 years in RA, 31.5 years in AS, 48.7 years in PsA, 38.0 years in ReA, 36.5 years in other SpA, 36.1 years in CTD, 65.0 years in crystalline arthritis, 53.3 years in viral arthritis, and 48.3 years in undifferentiated arthritis. Four of 11 children had juvenile idiopathic arthritis (JIA). The incidence of JIA was 23/100,000 in the population < 16 years of age. Of the remaining cases, 3 children had antibodies against Sindbis (Pogosta) virus and 4 had a transient monoarthritis. CONCLUSION: The overall incidence of arthritides among adults was slightly higher than previously reported from Finland. The incidence rates in the child population are in agreement with previous figures. These data are useful in planning the provision of health care.

MR imaging of inflammatory joint diseases of the foot and ankle.

Pain affecting the foot and ankle is a common complaint frequently attributable to inflammatory joint diseases. Although conventional radiography is regarded as the initial step in the diagnostic investigation, MR imaging may contribute to further evaluation of these patients due to the direct visualization of the inflammatory soft tissue formed in the disease and its effects on bone, cartilage and para-articular structures. The high spatial resolution of MR imaging combined with tissue characterization often allows initial detection of inflammatory joint abnormalities at a stage that precedes radiographic evaluation. The typical MR appearance of certain inflammatory joint disorders may be helpful in narrowing the wide differential diagnosis. Furthermore, MR imaging can be used for an exact assessment of the extent of the disorder as well as its complications. Accurate diagnostic information can guide the clinician in further diagnostic tests and implementation of proper therapeutic treatment.

A prospective clinical five year follow up study after open synovectomy of the knee joint in patients with chronic inflammatory joint disease. The prognostic power of clinical, arthroscopic, histologic and immunohistologic variables.

Arthroscopy and clinical examination was performed on the knee joint of 26 patients with chronic inflammatory joint disease, before and at 6 and 12 months after open synovectomy. Biopsies were examined by histologic and immunohistologic methods. Clinically the patients improved until 6 months after synovectomy, and the improvement was maintained for 5 years. Patients with the best clinical function prior to synovectomy also had the best long term results (p = 0.024). The state of the cartilage was the best predicting variable with a significant prognostic power (p = 0.01). Thus patients with normal cartilage at the time of synovectomy had the best clinical score five years later. The patients with most resynovitis 12 months after surgery did less well at five year clinical follow up (p = 0.032) than those with little or no resynovitis. Absence or low number of IgA-positive plasma cells in the cellular infiltrate at 12 months after surgery correlated with a good clinical score five years after surgery (p = 0.036). This suggests that a high number of IgA-positive plasma cells may be indicative of a more aggressive, destructive disease.

Multicomponent investigations of the hydrogen peroxide- and hydroxyl radical-scavenging antioxidant capacities of biofluids: the roles of endogenous pyruvate and lactate. Relevance to inflammatory joint diseases.

High field proton (1H) nuclear magnetic resonance (NMR) analysis of biofluids (health human blood sera and inflammatory knee-joint synovial fluids) has been employed to evaluate the hydrogen peroxide (H2O2)- and hydroxyl radical (0OH)- scavenging antioxidant capacities of a range of polar, low-molecular-mass endogenous metabolites therein. Data obtained indicate that consumption of H2O2 by pyruvate (generating acetate and CO2 via an oxidative decarboxylation reaction) and 0OH radical by lactate (generating pyruvate, and subsequently acetate and CO2) may serve to protect alternative biofluid components (e.g., macromolecules) against reactive oxygen species-mediated oxidative damage in vivo. The mechanistic, physiological and potential therapeutic implications of these results are discussed with special reference to inflammatory joint diseases.

Changes in proteoglycan content of articular cartilage during avian degenerative joint disease.

OBJECTIVE: To determine the biochemical changes in articular cartilage composition associated with the development of avian degenerative joint disease (DJD) in ad libitum fed broiler fowl, in comparison to feed-restricted broilers and J-lin fowl (non-susceptible to DJD). METHODS: Articular cartilage from the distal tibiotarsus (DTT) was characterised up to age 180 days. Proteoglycan content was determined by uronic acid and sulphated glycosaminoglycan analysis, cellularity by assay for DNA content, and collagen content and crosslinking by hydroxyproline and pyridinoline analysis, respectively. RESULTS: Disease development was accompanied by increased hydration and proteoglycan content (particularly sulphated proteoglycans) and decreased cellularity, with no significant differences in either total collagen content or in mature collagen cross-linking. CONCLUSION: The biochemical features of avian DJD are similar to those observed in other animal models. This bipedal model is exceptional however since cartilage alterations occur spontaneously and in a load-dependent manner.

[Intra-articular glucocorticoid injections in joint diseases].

Intra-articular glucocorticosteroid injections are widely used in mono- or oligoarticular flares of patients with rheumatoid arthritis and other aseptic inflammatory joint diseases, as well as in osteoarthritis. Rapid and pronounced, but usually temporary, suppression of local joint inflammation may be achieved with only minor systemic effect. In osteoarthritis the effect is brief and transient. Triamcinolone hexacetonide provides the longest clinical effect, but since this drug may cause local tissue necrosis when injected outside a synovial cavity it should be used only by experienced clinicians. The risk of glucocorticoid-induced cartilage damage is discussed. The risk is probably less than that of untreated joint inflammation. Nevertheless, it is recommended that injections into the same joint are limited, for instance to one injection every six weeks and no more than three or four in one year. Furthermore, indications and contraindications should be carefully considered prior to each injection. Intra-articular glucocorticoid therapy may be of considerable clinical value in the management of aseptic arthritis, if administered on correct indications using a correct technique.

Erosive temporomandibular joint disease as a feature of the spondyloarthropathy of ulcerative colitis.

A patient with ankylosing spondylitis associated with ulcerative colitis developed bilateral temporomandibular joint pain and severe restriction of jaw motion. Conventional radiographs did not show structural abnormality of the temporomandibular joints, but corrected axis tomography revealed erosions in both mandibular condyles with extensive reactive sclerosis in the subchondral bone. These findings suggest that the temporomandibular joint disease in this case was a feature of the patient's spondylitis rather than a manifestation of the peripheral joint arthritis which commonly occurs in patients with ulcerative colitis.
