RESUMO

Algunas enfermedades infecciosas han adquirido más relevancia por el aumento de los movimientos poblacionales. La eosinofilia es un hallazgo frecuente en inmigrantes y en viajeros. Una de las causas más frecuentes de eosinofilia es la infección por helmintos y algunos protozoos intestinales. El objetivo de este trabajo es describir las características epidemiológicas de los casos con eosinofilia y su asociación con la presencia de parásitos en la red de datos REDIVI. Se trata de un estudio observacional multicéntrico prospectivo, donde se incluyen los casos diagnosticados de eosinofilia registrados en la Red cooperativa para el estudio de las infecciones importadas por viajeros e inmigrantes (+REDIVI) desde enero de 2009 hasta diciembre de 2012. Se registraron en la red un total de 5.255 episodios durante el periodo de estudio, y la eosinofilia fue un hallazgo en el 8,1 al 31,3% de los casos (dependiendo del tipo migratorio). Fueron hombres el 60,2%, con una mediana de 31,0años, inmigrantes el 72,4% y asintomáticos el 81,2%. Los parásitos más frecuentemente identificados fueron S.stercoralis(34,4%), Schistosoma sp. (11,0%) y uncinarias (8,6%). Existía asociación entre eosinofilia y presencia de parásitos para todos los helmintos (excepto para larva migrans cutánea). La sintomatología y la duración del viaje no determinaron significativamente la presencia de eosinofilia. Ante una eosinofilia en una persona que ha vivido en zonas endémicas de helmintiasis es aconsejable realizar estudios dirigidos para su diagnóstico, independientemente del tipo migratorio, la duración de la estancia o la presencia de sintomatología (AU)


The population movements during the last decades have resulted in a progressively increasing interest in certain infectious diseases. Eosinophilia is a common finding in immigrants and travelers. One of the most common causes of eosinophilia is helminth infection, and some intestinal protozoa. The aim of this paper is to describe the epidemiological characteristics of cases with eosinophilia and its association with the presence of parasites in the REDIVI data network. This is a multicenter prospective observational study that includes patients diagnosed with eosinophilia registered in the cooperative network for the study of infectious diseases in travelers and immigrants (+REDIVI) from January 2009 to December 2012. A total of 5,255 episodes were recorded in the network during the study period, and eosinophilia was observed in 8.1-31.3% of cases (depending on the immigration group). There were 60.2% men, with a median age of 31years. There were 72.4% immigrants, and 81.2% were asymptomatic. The most commonly identified parasites were S.stercoralis (34.4%), Schistosoma sp. (11.0%), and hookworm (8.6%). The relationship between eosinophilia and parasite infection was significant for all helminths (except for cutaneous larva migrans). The symptoms and duration of the journey did not significantly determine the presence of eosinophilia. In the case of eosinophilia in a person who has lived in helminth endemic areas, it is advisable to carry out targeted studies to diagnose the infection, regardless of immigration type, length of stay, or the presence of symptoms (AU)

RESUMO

BACKGROUND: Leishmaniasis is endemic in many countries. The existence of different species combined with host factors may condition clinical presentation, treatment options, and disease outcome. In an endemic country, a predominance of certain species and presentations may be expected, whereas from the perspective of a tropical medicine referral unit a wider variety of cases from diverse geographical areas may be observed. METHODS: Retrospective study of imported leishmaniasis cases diagnosed at a Tropical Medicine referral unit in Spain, during the period of January 1995 to June 2008. RESULTS: In total, 18 cases were diagnosed: 12 cutaneous leishmaniasis (CL), 4 mucocutaneous leishmaniasis (ML), and 2 visceral leishmaniasis (VL) cases. Two patients were immunosuppressed. The majority of CL cases (9/12) occurring in travelers were acquired in New World countries and were treated with pentavalent antimonials. Three ML cases were acquired in the New World, two received initial treatment with pentavalent antimonials and two with liposomal amphotericin B (LAmB). For all four ML cases, a change in drug choice and multiple treatment courses were necessary, and one remained refractory to treatment. Both VL cases were acquired in Africa and responded well to LAmB treatment. CONCLUSION: The management of leishmaniasis in non-endemic countries is still a challenge for physicians. With the variety of cases presented, both in immigrants and travelers from different geographical areas, this series illustrates the great diversity of imported leishmaniasis in terms of presentation, treatment options, and outcome. We consider this entity is becoming increasingly more frequent and clinicians should be aware of strategies for its correct management.
