The systemic lupus erythematosus-like syndrome in MRL/lpr mice involves high-titered IgG autoantibodies, particularly antinuclear Abs that target histones, DNA, and RNA particles. Although T cell help is required for the generation of antinuclear Abs, the epitopes recognized by such helper T cells are unknown. To address this question, we isolated and sequenced self peptides bound by MHC class ...

scleroderma is a multisystem autoimmune connective tissue disease, cliaracterized by hardening of the skin. hv had 25 patients in the iranian pediatric unit of rheumatology over 10 years. there was female predominance if.m = 4/1, 80% female, 20% male). the age of onest was from 6 months to 16 years, the mean age being 10 years. the symptoms and signs were: nonpitting edema in 16%, liard skin in...

In order to investigate the association between IgG4 autoantibody and complement abnormalities in systemic lupus erythematosus (SLE), 72 newly diagnosed SLE patients, 67 rheumatoid arthritis (RA) patients, and 41 healthy normals were employed. Serum levels of antinuclear IgG4 and IgG4-specific IgM-rheumatoid factor (RF) were measured, and the correlations between serum levels of antinuclear IgG...

The antinuclear antibodies (ANA) test has been a cornerstone of the evaluation of connective tissue disease. The aim of this study was to investigate the diagnostic value of the ANA test in pleural or pericardial effusions of unknown causes. Over a 3-yr period, a total of 126 pleural fluid and 30 pericardial fluid samples were analysed. ANA tests were performed using a commercially available ki...

OBJECTIVE The relationship between human leukocyte antigens class II (HLA) and antinuclear antibodies was investigated in Jamaican patients with Systemic Lupus Erythematosus (SLE). METHODS Samples of blood of 82 patients with SLE and 75 healthy controls were tested for antinuclear antibodies using the fluorescent antinuclear antibody (FANA) test, counterimmunoelectrophoresis (CIEP) and the Cr...

The prevalence of antiphospholipid and antinuclear antibodies in 102 patients with at least three unexplained miscarriages before a gestational age of 12 weeks, or at least one intrauterine fetal death after 12 weeks, was investigated and compared with the prevalence in 102 normal pregnant controls. Six patients had a history of thrombosis and six had 'lupus-like' disease. Twenty one patients h...
