Abstract
Cisplatin-associated hemolytic-uremic syndrome (HUS), an under-reported form of HUS induced by chemotherapy, typically pursues a fulminant and lethal course. We report the cases of two patients with squamous cell carcinoma of the head and neck who developed massive hemolysis, profound thrombocytopenia, and dialysis-dependent renal failure after therapy with cisplatin. Plasma exchange was ineffective in both patients, but plasma perfusion with a staphylococcal protein A column produced a dramatic and permanent response in the second patient. These cases show the importance of considering HUS as a cause of renal failure in such patients who receive cisplatin-based chemotherapy, and support the role of staphylococcal protein A plasma perfusion as treatment for this condition.
