Serum samples from 22 patients with infective endocarditis were analysed for the presence of antibodies to cardiolipin, false positive Venereal Disease Research Laboratory (VDRL) test, and rheumatoid factor in order to determine the prevalence of anticardiolipin antibodies, their level, and to ascertain whether there was any correlation with the presence of rheumatoid factor. Although the latex...

Anticardiolipin antibodies are a group of antiphospholipid autoantibodies seen primarily in patients with systemic lupus erythematosus and other autoimmune diseases. We report 3 patients, 2 without systemic lupus, who suffered ischemic brain infarction associated with these antibodies in the absence of detectable lupus anticoagulant activity. Anticardiolipin antibodies, possibly associated with...

AIM To present the impact of parathyroidectomy on the spontaneous healing of necrotic lesions of the skin of the lower leg and on anticardiolipin antibodies regression in a 68-year-old female dialyzed patient with hyperparathyroidism and calcific-uremic arteriolopathy (CUA). METHODS After the occurrence of initial lesions of the lower leg skin, the intact parathyroid (iPTH) level, calcium (Ca...

A haemolytic assay was used to test the complement fixation ability of 16 serum samples with high concentrations of anti-cardiolipin antibodies. Fourteen patients had clinical complications usually associated with these antibodies--namely, recurrent abortions, thrombosis, or thrombocytopenia. Complement fixation by anticardiolipin antibodies was shown in only four of these patients and was not ...
