Short-course treatment with ceftriaxone for leptospirosis: A retrospective study in a single center in Eastern France

Short-course (less than 7 days) antibiotic treatments have been rarely assessed in the management of leptospirosis. We analyzed the charts of patients hospitalized with confirmed and probable leptospirosis in a teaching hospital between 1994 and 2012. Of 89 patients with confirmed or probable leptospirosis, 21 patients (11 confirmed, 10 probable - 14 uncomplicated and 7 severe forms) admitted between 2001 and 2012 received ceftriaxone (1-2 g daily) for less than 7 days. Apyrexia was obtained within 2 days of treatment in all patients and no relapse was observed. These data support the hypothesis that short-course treatments of 3-6 days with ceftriaxone (1-2 g per day) may be an option in the treatment of uncomplicated and severe forms of leptospirosis responding quickly to therapy. This hypothesis deserves being confirmed in further clinical studies. (C) 2014, Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases. Published by Elsevier Ltd.
