Thrombotic microangiopathy as an initial manifestation in HIV patients.

Thrombotic microangiopathy (TMA) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, microvascular thrombosis, and various organ dysfunctions. TMA usually occurs in a more advanced stage of HIV disease. TMA as an initial presenting feature is rare. We here report a male patient who presented with oliguric renal failure. Investigations revealed anemia, thrombocytopenia, schistocytes in peripheral smear, and HIV-positive. Renal biopsy revealed TMA. He was treated with hemodialysis and started on highly active antiretroviral therapy.
