Synovial fluid C3 was measured by electroimmunoassay. When C3 was expressed as mg/ml, the amounts found in Reiter's disease, psoriatic arthritis, gout, and systemic lupus erythematosus were significantly different from degenerative arthritis. When C3 was corrected for total protein, the levels for rheumatoid arthritis, Reiter's disease, psoriatic arthritis, and systemic lupus were significantly different from degenerative arthritis. When C3 was corrected for synovial fluid globulin, only rheumatoid arthritis and systemic lupus were significantly different from degenerative arthritis. Correction of C3 for globulin increases the difference between rheumatoid arthritis and degenerative arthritis. A proportion of gouty fluids with a relative decrease in C3 is demonstrated. It is argued that correction of C3 for globulin is more meaningful than correction for total protein. While many nonrheumatoid inflammatory effusions demonstrate split products of C3, the majority of fluids from patients with systemic lupus have none.

We have conducted an immunocytochemical analysis to investigate the presence of the recently described vascular cell adhesion molecule-1 (VCAM-1) in human kidney, using the anti-VCAM-1 monoclonal antibody 1.4C3. In normal control tissue VCAM-1 was present on some (but not all) parietal epithelial cells lining Bowman's capsule. Forty-nine of fifty clinical biopsy specimens were characterised by the additional presence of VCAM-1 on proximal tubular cells. This was most marked in biopsies of patients with interstitial nephritis or systemic vasculitis with crescentic nephritis, but was also observed in biopsies with minimal change, IgA or lupus nephropathy, or from patients with diabetic nephropathy, amyloid, or gout. Proximal tubule VCAM-1 correlated significantly with the number of transferrin-receptor-positive leukocytes (r = 0.607, p less than 0.0001) in the interstitium, but not with expression of HLA-DR by tubular cells. Surprisingly, VCAM-1 was not observed on vascular endothelial cells in these biopsies, even in the presence of a marked infiltrate; this contrasts with other tissues (e.g. skin and synovium). The presence of VCAM-1 on tubular cells in the inflamed kidney indicates the potential for these cells to interact with mononuclear cells, either as accessory cells or as cytotoxic targets. The unexpected absence of VCAM-1 in renal vascular endothelial cells suggests local differences in the endothelial cells of this organ.

Levels of interleukin-2 receptors (IL-2R), as measured by a double-antibody "sandwich" enzyme-linked immunosorbent assay technique, were markedly elevated in the serum of patients with systemic lupus erythematosus, rheumatoid arthritis, and bacterial endocarditis, but not in patients with acute gout. Serum levels of IL-2R correlated strongly with clinical and laboratory indicators of disease activity in patients with lupus and in those with rheumatoid arthritis. This relationship was confirmed by sequential determinations in individual patients. Serum IL-2R values correlated with disease activity better than did the Westergren erythrocyte sedimentation rate. Our findings indicate that serum levels of IL-2R may serve as a reliable serologic indicator of disease activity in inflammatory diseases characterized by immune system activation.

First degree relatives and spouses of 36 patients with systemic lupus erythematosus (SLE) and 37 with discoid lupus erythematosus (LE) were assessed using the ARA criteria. They were compared with relatives and spouses of patients with other rheumatic and related complaints. Definite SLE was present in 3.9% of relatives of SLE probands, 2.6% of discoid relatives and 0.3% of controls. Discoid LE was diagnosed in 0.6% of SLE and 3.5% of discoid families compared with 0.5% of controls. None of the spouses of LE probands had SLE or discoid LE. The data gave the best fit for a polygenic inheritance with a heritability of 66 +/- 11% for SLE and 44 +/- 10% for discoid LE. Genetic factors are thus less important in SLE and discoid LE than in generalized osteoarthritis, spondylitis or gout with heritabilities of 90, 72 and 90%, respectively.

An attempt is made to see if any correlation exists between the prevalence of 13 selected rheumatic diseases and the number of literature entries concerning these disorders in 1974 and 1983. Entries on systemic lupus are broken down in detail. It is concluded that interest in autoimmune diseases, especially their immunology, appears healthy. Lower morbidity disorders with a large prevalence (osteoarthritis, fibrositis, gout) may be disproportionately under-investigated. Whether any correlation between funding levels and literature entries can be made is speculative.

Radiographs of patients with rheumatoid arthritis can sometimes be misleading. Seven of 69 patients with RA had radiographs sufficiently atypical to lead clinicians to suspect other disorders (e.g., gout, lupus erythematosis, thrombophlebitis). Five of these cases are presented and the diagnosis in each case is discussed.

Based on their own experience, the authors report that a fall in the complement level of joint fluid, which is particularly common in rhumatoid arthritis, is also seen in cases of systemic lupus eryrthematosis and a variety of arthritis: infectious arthritis, gout, articular chondrocalcinosis and psoriatic rheumatism. This should be taken into account when evaluating the diagnostic value of this test in rheumatoid arthritis.

Six of seven patients with Lyme arthritis were positive by PCR. In contrast, all 18 synovial fluid samples from patients with other disorders, including rheumatoid arthritis, spondyloarthropathy, gout, pseudogout, hemarthrosis, degenerative joint disease, lupus, papillary synovitis, and trauma, were negative by PCR (P < 0.001, Lyme arthritis compared with controls, Fisher exact test). All 38 laboratory controls were negative by PCR. The assay reproducibly detected 20 or fewer B. burgdorferi cells directly or when added to extracted synovial fluid that was previously negative by PCR. Polymerase chain reaction was done four times with identical results, including analyses with both outer surface protein A primer sets.

Conflicting data exist with respect to the existence and clinical manifestations of a hyperlipidemic arthropathy. Reasonable evidence supports the existence of a migratory polyarthritis similar to rheumatic fever in patients homozygous for type II hyperlipidemia. Although similar complaints have been described in patients heterozygous for this condition, findings have been inconsistent among various reports. It is possible that high lipid levels are required to induce rheumatic complaints, and these are found predominantly in homozygous patients. Even so, rheumatic syndromes appear to be more attributable to periarthritis because evidence of inflammatory arthritis is largely lacking. In contrast, Achilles tendinitis appears to be associated with heterozygous type II hyperlipidemia and presumably is based on lipid deposits within the tendon. Gout is an accepted association of type IV hyperlipidemia. In addition, oligoarticular symptoms have been described with type IV hyperlipidemia. However, no consistent clinical entity has emerged. Drugs used in the treatment of hyperlipidemia are associated with a variety of rheumatic problems, including proximal myopathy and lupus-like syndromes. The most commonly implicated drugs are the hydroxymethylglutaryl-coenzyme A reductase inhibitors and the fibric acid derivatives.

Systemic lupus erythematosus (SLE) and gout have been associated infrequently. We describe 3 young adults with SLE who developed tophaceous gout relatively early in the course of their disease. All were underexcretors of uric acid but were studied after the development of renal disease; 2 were treated with diuretics. In 2 cases, gout became obvious while lupus was quiescent.
