Abstract

A man in his early 30s presented with sudden-onset respiratory distress, haemoptysis and reduced urine output. He was in volume overload with a blood pressure recording of 240/180 mm Hg. Pulmonary renal syndrome was suspected and he was initiated on plasmapheresis, followed by steroid pulse therapy. Chest radiography and the presence of fragmented red cells on the peripheral smear were unexplained. These were later explained by hypertensive nephropathy and thrombotic microangiopathy changes on renal biopsy. His respiratory and haematological parameters improved with blood pressure control. Malignant hypertension closely resembles pulmonary renal syndrome, which must be remembered in order to avoid plasmapheresis and high-dose immunosuppressive therapy.
