background: the prevalence of anti-neutrophil cytoplasmic antibodies (ancas) and anti-cardiolipin antibodies (anti-cl ab) in behcet’s disease (bd) and also their roles in vascular involvement is controversial. objective: to assess the prevalence of ancas and anti-cl ab as well as their correlations with clinical manifestations in iranian patients with bd. methods: in this case/control study, th...

the central immunological disturbance in systemic lupus erythematosus (sle) is autoantibody production. some of these antibodies affecting components of the cell nucleus are the major characteristics of sle. the present study was aimed to assess importance of anticardiolipin (acl) antibody and its association with clinical state in sle patients. a cross sectional study was performed on 100 pati...

Anticardiolipin antibodies are produced both in patients with the antiphospholipid syndrome (APS) and in patients with syphilis, but lupus anticoagulant activity has been reported only for the former group. To understand these differences, affinity-purified immunoglobulin G anticardiolipin antibodies from APS (n = 11) and syphilis (n = 5) patients were compared. Only the antibodies from the APS...

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 ...

A 23 year old woman with systemic lupus erythematosus and antiphospholipid syndrome developed severe thrombocytopenia (5-10 X 10(9)/l) and cerebral infarction. Treatment with high doses of corticosteroids and cytostatic drugs was not effective. The condition was successfully treated only when three courses of intravenous gammaglobulin at 400 mg/kg daily was added. A clear relation was found bet...
