Leptospirosis is a zoonosis of global importance caused by Leptospira interrogans. The aim of this study was to compare the data between children, adolescents and adults with leptospirosis. This is a retrospective study including a total of 373 consecutive patients with leptospirosis, admitted to tertiary hospitals in Northeast of Brazil, from May 1985 to August 2010. The patients were divided into two groups (age ≤21 years and >21 years). The adults were 304 (81.5%) of the population, with a mean ge of 41 ± 13 (range 22‑84) years. The pediatric group was 16 ± 3 (range 9‑21) years. Signs and symptoms where similar between the groups, excepting arrhythmia, which was more frequent in adults and vomiting, more common in children (16% vs. 0%, P = 0.04 and 65% vs. 79%, P = 0.02), respectively. Adult group presented with higher serum urea (137 vs. 97 mg/dl, P = 0.002) and creatinine (4.3 vs. 3.0 mg/dl, P = 0.007). Acute kidney injury (AKI) was observed in 80%, mainly in adults (83% vs. 70% P < 0.005). Adults required renal replacement therapy more frequently than children (38% vs. 11%, P < 0.0001). Mortality was higher in adults (14.8% vs. 2.8%, P = 0.005) and in adults with AKI (93% vs. 7%, P < 0.05). There are important differences between the adults and children with leptospirosis. AKI was more frequent in adults and it was associated with increased mortality.
