RESUMO
Schistosomiasis is a highly prevalent disease, especially in immigrant populations, and is associated with significant morbidity and diagnostic delays outside endemic areas. For these reasons, the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the Spanish Society of Tropical Medicine and International Health (SEMTSI) have developed a joint consensus document to serve as a guide for the screening, diagnosis and treatment of this disease outside endemic areas. A panel of experts from both societies identified the main questions to be answered and developed recommendations based on the scientific evidence available at the time. The document was reviewed by the members from both societies for final approval (AU)
La esquistosomiasis es una enfermedad de elevada prevalencia, especialmente en población inmigrante, asociada a importante morbilidad y retraso diagnóstico fuera de zona endémica. Por estas razones, la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC) y la Sociedad Española de Medicina Tropical y Salud Internacional (SEMTSI) han elaborado un documento conjunto de consenso que sirva de guía para el cribado, diagnóstico y tratamiento de esta patología en zonas no endémicas. Un panel de expertos de ambas sociedades identificó las principales preguntas a responder y elaboró las recomendaciones siguiendo la evidencia científica disponible en el momento. El documento fue revisado por los miembros de ambas sociedades para su aprobación final (AU)

Background: Earlier studies found characteristic haematological changes in African patients with active schistosomiasis. If consistently present, full blood counts (FBC) may be helpful to diagnose schistosomiasis also in migrants and returning travellers. Methods: A retrospective patient record review was conducted on data from seven European travel clinics, comparing FBC of Schistosoma egg-positive travellers and migrants to reference values. Sub-analyses were performed for children, returned travellers, migrants and different Schistosoma species. Results: Data analysis included 382 subjects (median age 21.0 years [range 2-73]). In returned travellers, decreases in means of haemoglobin particularly in females (ß = -0.82 g/dL, p = 0.005), MCV (ß = -1.6 fL, p = 0.009), basophils, neutrophils, lymphocytes and monocytes (ß = -0.07, p < 0.001; -0.57, p = 0.012; -0.57, p < 0.001 and -0.13 103/µL, p < 0.001, respectively) were observed. As expected, eosinophils were increased (ß = +0.45 103/µL, p < 0.001). In migrants, a similar FBC profile was observed, yet thrombocytes and leukocytes were significantly lower in migrants (ß = -48 103/µL p < 0.001 and ß = -2.35 103/µL, p < 0.001, respectively). Conclusions: Active egg-producing Schistosoma infections are associated with haematological alterations in returned travellers and migrants. However, these differences are discrete and seem to vary among disease stage and Schistosoma species. Therefore, the FBC is unsuitable as a surrogate diagnostic parameter to detect schistosomiasis.

RESUMO
El primer brote conocido de virus ebola ocurrió en 1976, y desde entonces habían sido comunicados otros 24 brotes esporádicos circunscritos a África Central que nunca sobrepasaron los 425 afectados. El brote actual de ebola de África Occidental es el mayor de la historia, ha afectado a 28.220 personas y ha causado 11.291 muertos hasta la fecha. La magnitud de la epidemia ha producido una alarma mundial. Por primera vez se han atendido pacientes en países fuera de África y se han producido casos secundarios en España y en Estados Unidos. La epidemia actual ha hecho avanzar el conocimiento sobre la epidemiología, la clínica, las manifestaciones de laboratorio y la virología de la enfermedad por virus ebola. Por primera vez se han utilizado tratamientos experimentales y se han producido grandes avances en el desarrollo de vacunas. En el presente artículo revisamos estos avances en el conocimiento de la enfermedad por virus ebola
The first known Ebola outbreak occurred in 1976. Since then, 24 limited outbreaks had been reported in Central Africa, but never affecting more than 425 persons. The current outbreak in Western Africa is the largest in history with 28,220 reported cases and 11,291 deaths. The magnitude of the epidemic has caused worldwide alarm. For the first time, evacuated patients were treated outside Africa, and secondary cases have occurred in Spain and the United States. Since the start of the current epidemic, our knowledge about the epidemiology, clinical picture, laboratory findings, and virology of Ebola virus disease has considerably expanded. For the first time, experimental treatment has been tried, and there have been spectacular advances in vaccine development. A review is presented of these advances in the knowledge of Ebola virus disease
