IgG antinuclear antibodies (ANAs) are elevated in patients with systemic lupus erythematosus (SLE) compared with patients with discoid lupus erythematosus (DLE). To provide an expanded immunologic view of circulating ANAs in lupus patients, we compared the expressions of IgG, IgM, and IgA ANAs in DLE and SLE patients. In this cross-sectional study, sera from age-, gender-, and ethnic-matched SL...

Kikuchi Fujimoto Disease (KFD), also known as necrotic histiocystic lymphadenitis, is a condition with unknown etiology. Probably, infectious, viral, and also autoimmune etiologies, especially lupus erythematosus, contribute to this disorder. The common signs are lymphadenopathy along with fever and leukopenia. Our case was a13-year-old boy with fever of unknown origin. He underwent ordinary fe...

Background—Sulphasalazine (SSZ) has been reported to cause drug induced systemic lupus erythematosus (SLE), but diagnosis of this complication in the context of rheumatoid arthritis (RA) is diYcult. Objective—To determine prospectively: (1) if patients become seropositive for antinuclear antibodies (ANA) during prolonged treatment with SSZ without clinical evidence of SLE; (2) if ANA positive p...

The basis of autoimmune diseases such as SLE (Systemic Lupus Eritematodes), Sjogren's syndrome, scleroderma, dermatomyositis and polymiositis is the creation of auto-antibodies to the following specific extractable nuclear antigens (ENA):Jo-1, Ssl-70, SS-A, SS-B, Sm and Sm/RNPs. Some of these antigens are in fact enzymes (Jo-1-histidil-tRNA synthetase, Scl-70-topoisomerase) which are inhibited ...

INTRODUCTION Limited data is available regarding the clinical manifestations and pattern of Systemic Lupus Erythematosus (SLE) in Sudan. This study aimed to determine the clinical manifestations and Antinuclear Antibodies (ANA) profile among Sudanese adults with SLE and lupus nephritis (LN). METHODS A descriptive study was conducted in Omdurman Military Hospital, Sudan. It included all adults...

Circulating antinuclear antibodies (ANA) are commonly present in the systemic autoimmune disease Systemic Lupus Erythematosus (SLE) and in other systemic rheumatic diseases, in humans as well as in dogs. The indirect immunofluorescence (IIF)-ANA test is the standard method for detecting ANA. Further testing for specific ANA with immunoblot techniques or ELISAs is routinely performed in humans t...

Lupus nephritis (LN) is a serious and common complication of systemic lupus erythematosus (SLE) that predisposes to significant morbidity and mortality. Studies show that prompt diagnosis and treatment improves patient survival. We present a case of a 49-year-old female with an atypical presentation of LN who initially presented with new-onset hypertension, edema, arthritis, serositis and recen...

FcgammaRIIB is a potent lupus susceptibility gene as demonstrated by the observation that mice deficient in this molecule develop spontaneous antinuclear antibodies (ANA) and fatal glomerulonephritis when on the C57BL/6 background. To determine the mechanisms underlying the epistasis displayed by this gene we have constructed hybrids between FcgammaRIIB(-/-) and the systemic lupus erythematosus...
