Probing for genes in seronegative spondyloarthropathy.

Seronegative spondyloarthropathies are a group of disorders characterized by inflammation of the spine, sacroiliac joints, and peripheral arthritis along with various characteristic extra-articular features. Their pathogenesis and immunogenetics have not yet been fully elucidated. Ankylosing Spondylitis (AS) is probably the best studied of these disease. It has now been 27 years since the association of human leukocyte antigen (HLA) B27 and AS has been demonstrated. Since then, a plethora of association studies and linkage studies unequivocally demonstrate that genetic determinants within or near the major histocompatible complex (MHC) are critical to the etiology of AS. Surprisingly though, the total MHC contribution to AS has been estimated at only 30%. In this review, we highlight the genetic basis of AS as the prototypical chronic axial arthritis, and discuss the rationale and approach in searching for non-HLA linked genes.

Systemic sclerosis (scleroderma) in two iron ore mines.

Six males with systemic sclerosis were observed in the work forces of two iron ore mines. The usual spectrum of clinical features encountered in systemic sclerosis patients were present. Histologic examination of pulmonary tissue was performed on three of the cases and showed features of both silicosis and scleroderma but to different degrees and stages of development. Exposure to high levels of silica-containing dusts had occurred in all six cases.

The role of anti-malarials in rheumatoid arthritis--the American experience.

Rheumatoid Arthritis (RA) is a chronic disease with significant morbidity and functional disability. The traditional treatment for RA relied on the use of NSAIDs early in the disease course, followed by disease-modifying agents later. More recently, the disease-modifying anti-rheumatic drugs (DMARDs) have become the mainstay of RA therapy because of the recognition of their superior efficacy/toxicity profile. The antimalarial drugs, chloroquine and hydroxychloroquine, are some of the most commonly used DMARDs in the management of RA. They have been shown to be significantly more effective than NSAIDs alone in several clinical trials, and have a benign toxicity profile. A combination of hydroxychloroquine with methotrexate appears to reduce significantly the hepatic toxicity of methotrexate. In this review, we summarize the efficacy and toxicity profiles of the antimalarial drugs in rheumatoid arthritis.

HLA antigens in North American patients with Takayasu arteritis.

OBJECTIVE: To determine the frequency of HLA class I and II antigens in Caucasian North American patients with Takayasu arteritis (TA). METHODS: Seventy-three class I antigens and 13 class II antigens were examined in 21 Caucasian North American patients with TA, and their frequencies were compared with findings in 243 healthy, untreated controls. HLA typing was performed by microlymphocytotoxicity assay. RESULTS: We found no statistically significant positive association of TA with DR2, DR4, DQw3, or any of the other class I or class II antigens studied. A negative association between TA and DR1 was noted. There was no significant association between any of the HLA antigens and the severity of the disease or the presence of complications. CONCLUSION: The negative association between TA and the DR1 antigen suggests that this antigen may be protective against the development of the disease.
