[Irreversible sequels of leptospirosis].

Leptospirosis is a zoonotic feral nidal disease (synonyms: Weil-Vasilyev disease, waterborne fever) running as an acute febrile disease with evident intoxication, renal, hepatic, and central nervous system involvements, evolving hemorrhagic syndrome mainly with its severe complicated course and high mortality rates. The clinical features of leptospirosis have been little studied in patients with comorbidities. Its poor outcomes are generally due to the development of serious complications, such as infection-toxic shock, acute renal and hepatic failure, massive hemorrhagic syndrome, infectious myocarditis, etc.
