The presence of anti-phospholipid antibodies (APA) (lupus anticoagulant, LA and anti-cardiolipid antibody, ACA) has recently been reported in polytransfused patients of beta thalassemia. In this study 50 patients with beta thalassemia major (beta-TM) who had received at least 20 transfusions were evaluated for presence of antiphospholipid antibodies and correlated with a number of clinical and hemostatic parameters. About 32% cases had developed a minor bleeding tendency and one also showed ecchymotic patch. None of the patients had thromboembolic episodes. LA was seen in 16% of cases. The mean age and number of transfusions were higher in LA positive patients as compared to LA negative patients however the results were not statistically significant. IgM ACA were detected in 6% of patients but no statistically significant correlation was found with age, number of transfusions, platelet count and coagulation parameters. IgG ACA were detected in 30% of cases and showed a significant correlation with number of blood transfusions (p = 0.016) and age (p = 0.031). Anti HCV antibodies were detected in 30% of patients out of which 1 had IgM ACA and 10 had IgG ACA. The latter showed a significant correlation with HCV infection. An increased incidence of LA and IgG ACA is found in polytransfused patients with beta-TM when compared to the normal healthy population but their clinical significance is yet not clearly understood. | | Language | eng | | Pub Type(s) | Journal Article
