A retrospective analysis of clinical profile of the patients positive for antiphospholipid antibodies (150) that are lupus anticoagulant (83) and anticardiolipin antibodies (57) was carried out from January 2015 to December 2016 in Kasturba Medical College, Manipal. The diagnosis of lupus anticoagulants was based on prolongation of dRVVT, its absence of correction with normal plasma and correction by phospholipids. The presence of antiardiolipin antibodies was based on the technique ELISA (uolmmun). Out of 150 patients positive for antiphospholipid antibodies, the mean age of presentation was 38 years, more commonly seen in the women. The frequency of thrombosis in patients positive for lupus anticoagulants was 55.5% (46), more commonly of venous origin and in the lower limbs. The frequency of patients with lupus anticoagulants presenting with abortion was 26 (31.3%), immune thrombocytopenic purpura, was 80% (67), valvular heart disease was 5 (6%), 35 (42.1%) patients had secondary LA due to autoimmune diseases like SLE, Sjogerns, APS. Anticardiolipin antibodies were present in 57 patients, more common in women. Thrombosis was seen in 28 (49%) patients, more of venous origin and in the lower limbs. Other clinical manifestations were abortions seen in 8 (9%) patients, immune thrombocytopenic purpura seen in 18 (32.5%) patients, valvular heart diseases seen in 8 (14%) of the patients and autoimmune diseases seen in31.3% of the patients. Patients positive for both lupus anticoagulant and anticardiolipin antibodies (10) had a higher rate of thrombosis around 60%, more commonly of venous origin and had higher associations with autoimmune diseases (80%).
