UNLABELLED: INDRODUCTION: Leptospirosis is a frequent cause of febrile illness around the world, particularly in tropical and subtropical areas such as Perú. OBJECTIVE: To estimate the frequency and socio-demographic characteristics associated with leptospirosis in febrile patients in northern Perú. MATERIALS AND METHODS: A cross sectional study was conducted from January to December 2014 in 143 fever cases admitted to the Hospital Regional Lambayeque, Perú. Structured for socio-demographic information and sanitation questionnaire was used. Serum samples were examined to quantitatively determine the presence of IgM antibodies to leptospira using ELISA IgM. RESULTS: The frequency was 26.6% (95% CI 19.3 to 33.8) and independently associated features were: be between 20-54 years (OR: 3.36, 95% CI 1.17 to 9, 64), work in agriculture-livestock (OR: 6.15, 95% CI 1.99 to 19.05),contact with animals (OR: 4,13, IC 95%: 1,76-9,65) and consumption of unsafe water(OR: 3,33, IC 95%: 1,49-7,43). CONCLUSIONS: This study reveals a high frequency of leptospirosis among febrile patients from northern Perú. These results indicate the need to investigate routinely leptospirosis in febrile patients, especially those exhibiting risk characteristics.

Introducción: La leptopsirosis es causa frecuente de enfermedad febril alrededor del mundo, en particular en áreas tropicales y subtropicales como Perú. Objetivo. Estimar la frecuencia de leptospirosis y características socio-demográficas asociadas en pacientes febriles del norte del Perú. Material y Métodos: Se realizó un estudio transversal entre enero y diciembre de 2014 en 143 casos febriles admitidos en el Hospital Regional Lambayeque, Perú. Se usó un cuestionario estructurado para obtener información socio-demográfica y de saneamiento. Se examinaron muestras de suero para determinar cuantitativamente la presencia de anticuerpos IgM contra leptospira usando la técnica de ELISA IgM. Resultados: La frecuencia fue de 26,6% (IC 95%: 19,3-33,8) y las características asociadas independientemente fueron: tener entre 20 y 54 años (OR: 3,36, IC 95%: 1,17-9,64), dedicarse a la agricultura/ganadería (OR: 6,15, IC 95%: 1,99-19,05), el contacto con animales (OR: 4,13, IC 95%: 1,76-9,65) y el consumo de agua no potable (OR: 3,33, IC 95%: 1,49-7,43). Conclusiones: Este estudio revela una alta frecuencia de leptospirosis entre los pacientes febriles procedentes del norte del Perú. Estos resultados indican la necesidad de investigar la leptospirosis rutinariamente como causa de enfermedad febril, especialmente entre aquellos pacientes que presentan características de riesgo.
