Acute renal failure and severe rhabdomyolysis in a patient with resistant thrombotic thrombocytopenic purpura

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening disorder. This paper describes the case of a 39-year-old Sudanese male who presented to the emergency room with fever, jaundice, decreased level of consciousness, and worsening kidney function for 7 days, a high lactate dehydrogenase level (1947), severe thrombocytopenia (platelets 8), and numerous schistocytes in the peripheral blood smear. The patient was admitted with a diagnosis of TTP for plasma exchange. Fourteen days later, his creatinine kinase (CK) level rose to >50,000 IU; rhabdomyolysis was suggested. Continuous venovenous hemodialysis (CVVHD) was started. The patient’s CK level remained high, despite CVVHD, until the 6th day, after which this parameter gradually started to decrease. This report highlights a resistant case of TTP that presented with concomitant severe rhabdomyolysis, which demanded aggressive, continuous intervention.
