Cissus quadrangularis-Induced Thrombocytopenia in a Renal Allograft Recipient

An elderly male renal allograft recipient presented with thrombocytopenia. He had a kidney transplant for diabetic kidney disease and was on azathioprine and prednisolone. He had taken Cissus quadrangularis capsules for backache. A bone marrow aspiration to evaluate the cause of thrombocytopenia showed megakaryocyte hyperplasia, suggesting peripheral destruction. Repeat platelet counts after stopping Cissus quadrangularis showed normal levels.
