Abstract
Leptospirosis has a wide spectrum of clinical manifestations. Acute renal failure, an important complication, generally involves interstitial and tubular damage. We describe the case of a 42-year-old man who was admitted with fever, back pain and periorbital oedema. He had hypertension, thrombocytopenia, acute renal failure, hypoalbuminaemia, hypertriglyceridaemia and proteinuria >4.00 g/l. The renal biopsy showed mesangioproliferative glomerulonephritis. Due to the epidemiological context and clinical picture, ceftriaxone was started with rapid clinical improvement. Blood PCR for leptospira came back positive. The presentation of leptospirosis as nephrotic syndrome is rare and this diagnosis should be considered before performing a renal biopsy.
