[Systemic leptospirosis as a cause of multiple organ failure. Report of a case].

Leptospirosis is a world-spread zoonosis that is incidentally acquired by humans. It causes a diphasic febrile illness in which the Weil syndrome is its severest form, with renal, hepatic, clotting and central nervous system involvement. We report a 73 years old male, that was admitted to an intensive care unit with multiple organ failure due to leptospirosis. The clinical picture initially resembled a sepsis due to biliary tract obstruction and was operated, not finding a biliary tract obstruction. Considering the history of a fall to sewed waters, leptospirosis was suspected and treatment with penicillin was started, obtaining a full recovery of the patient.
