Abstract
Anticardiolipin antibody (ACA) levels were determined in 17 Asian female SLE patients with autoimmune haemolytic anaemia (AIHA) and 29 Asian female SLE inpatients without AIHA (control patients). Both IgG and IgM isotypes were measured by ELISA. Elevated IgM APA titres (>5 SD of normal health controls) were seen in 11 (64.7%) of 17 AIHA patients and six (20.7%) of 29 control patients(PP<0.05). None of the control SLE patients with thrombocytopenia had raised IgM ACA levels and only one had an elevated IgG ACA titre. Autoimmune haemolytic anaemia occurring in the context of SLE frequently associated with the concomitant presence of thrombocytopenia (Evan's syndrome) and with the presence of ACA.Keywords
