[Gastrointestinal bleeding and acute hepatic failure by leptospirosis: an entity that should not be forgotten]. / Hemorragia digestiva e insuficiencia hepática aguda por leptospirosis: una entidad que no debemos olvidar.

Leptospirosis disease is caused by the spirochete Leptospira. It is a worldwide distribution zoonosis, with predominance in the tropics. In Spain, it is not frequent but some cases have been noticed especially in humid areas surrounded by rivers, lakes or ponds, such as Catalonia, Andalucia or the Valencian Community. It is transmitted by a variety of animals such as cows or rats, that are infected either by direct contact with these animals or their urine, or indirectly by consuming or being in contact with water contaminated by their urine. The clinical manifestations are very variable, being asymptomatic or not very symptomatic in most of the patients. Unusually, leptospirosis presents with a first phase with fever, myalgias, liver injury or different organs hemorrhage, followed by a second phase with the presence of jaundice due to hepatic failure. Weil's disease is a kind of severe leptospirosis characterized by hepatic failure with jaundice and acute renal failure, associated with high mortality rates.The diagnosis is based on serological techniques and DNA detection by PCR. The treatment consists of life support measures and antibiotic therapy. A patient with Weil's disease and leptospirosis digestive bleeding is presented, with a fulminant clinical course. In order to achieve an early diagnosis, the need to keep this entity in mind must be emphasized, especially in favorable epidemiological environments as the one of this patient.

La leptospirosis es una enfermedad causada por la espiroqueta Leptospira. Se trata de una zoonosis de distribución mundial, con predominio en los trópicos. En España no es frecuente pero sí se observan casos en zonas más húmedas o con presencia de ríos, lagos o estanques, como son Cataluña, Andalucía o la Comunidad Valenciana, donde se relaciona con los arrozales. Los transmisores son múltiples animales como vacas o ratas, contagiándose el ser humano mediante contacto directo con estos animales o su orina, o bien de forma indirecta al consumir o estar en contacto con agua contaminada por la orina de éstos. Las manifestaciones clínicas son muy variables, siendo asintomática o poco sintomática en la mayoría de los pacientes. Aunque no ocurre siempre, la leptospirosis cursa con una primera fase con fiebre, mialgias, afectación renal o hemorragia de distintos órganos, seguida de una segunda fase con presencia de ictericia por afectación hepática. La enfermedad de Weil es una forma de leptospirosis grave caracterizada por afectación hepática con ictericia e insuficiencia renal aguda, asociada a una considerable mortalidad. El diagnóstico se basa en técnicas serológicas y detección de DNA mediante PCR. El tratamiento consta de medidas de soporte y antibioticoterapia. Presentamos un paciente con enfermedad de Weil y hemorragia digestiva por leptospirosis, con una evolución clínica fulminante, y hacemos hincapié en la necesidad de tener presente esta entidad, especialmente en ambientes epidemiológicos favorables como el de este paciente, con el fin de lograr un diagnóstico precoz.
