Background: Because early recognition and initiation of antibiotic therapy are important, clinicians should familiarize themselves with the clinical presentation of leptospirosis, and determine prognostic factors.
Patients And Methods: This study included all patients treated at Angers University Hospital between January 1995 and December 2005 for leptospirosis - both probable (cases combining epidemiologically suggestive features with compatible clinical, laboratory, and radiographic findings, with no other diagnosis envisioned) and confirmed (by finding microorganism on direct examination or culture of blood, urine or CSF, or by seroconversion or by a significant increase in the antibody titer between two samples). Severe leptospirosis was defined by hospitalization in the critical care department or need for renal dialysis.
