Fluctuations of anticardiolipin antibody levels in patients with systemic lupus erythematosus: a prospective study.

Prospective study of fluctuations of lupus anticoagulant activity and anticardiolipin antibody titre in patients with systemic lupus erythematosus.

Fluctuations of lupus anticoagulant activity and anticardiolipin antibody titres were studied in 53 patients with systemic lupus erythematosus (SLE). The median study time was 26 months with a median number of 12 samples. Lupus anticoagulant was measured by the kaolin clotting time (KCT) and dilute Russell viper venom time (dRVVT) assays; anticardiolipin antibodies were assayed by an enzyme lin...

Anticardiolipin Antibodies in Juvenile Rheumatoid Arthritis and Systemic Lupus Erythematosus

Background: Antiphospholipid antibody syndrome (APS) can either occur as a primary syndrome or associated with other autoimmune diseases such as systemic lupus erythematosus (SLE). Anticardiolipin antibody (aCL) of IgG and/or IgM isotype in blood, measured by a standardized ELISA is the most acceptable laboratory criteria. APS IgG isotype, particularly IgG2 subclass is more strongly associated ...

Increased Serum Levels of Soluble B7-H4 in Patients with Systemic Lupus Erythematosus

Anticardiolipin antibodies in patients from Malaysia with systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is highly prevalent in Malaysia, which has a mixed population of Malays, Chinese, and Indians. A quantitative enzyme linked immunosorbent assay (ELISA) was used to determine anticardiolipin antibody (aCL) levels (total immunoglobulin, IgG, and IgM) in 200 patients with SLE (164 Chinese, 26 Malay, and 10 Indian) attending the University Hospital of Kuala Lumpur...

Pyoderma gangrenosum in a patient with antiphospholipid antibody negative systemic lupus erythematosus: A case report

In any description of leg ulcers in systemic lupus erythematosus (SLE), pyoderma gangrenosum (PG) earns a mention at least for its being quite rare in such patients. The causative role of aPL (antiphospholipid antibody) in dermatological manifestations of SLE is undermined by the occurrence of PG in aPL negative SLE patients. To the best of our knowledge, there are only two reports of PG in aPL...
