Executive summary of imported infectious diseases after returning from foreign travel: Consensus document of the Spanish Society for Infectious Diseases and Clinical Microbiology (SEIMC) / Resumen ejecutivo de las enfermedades infecciosas importadas después de regresar de viajes en el extranjero: Documento de consenso de la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica

In a global world, knowledge of imported infectious diseases is essential in daily practice, both for the microbiologist-parasitologist and the clinician who diagnoses and treats infectious diseases in returned travelers. Tropical and subtropical countries where there is a greater risk of contracting an infectious disease are among the most frequently visited tourist destinations. The SEIMC considers it appropriate to produce a consensus document that will be useful to primary care physicians as well as specialists in internal medicine, infectious diseases and tropical medicine who help treat travelers returning from tropical and sub-tropical areas with infections. Preventive aspects of infectious diseases and infections imported by immigrants are explicitly excluded here, since they have been dealt with in other SEIMC documents. Various types of professionals (clinicians, microbiologists, and parasitologists) have helped produce this consensus document by evaluating the available evidence-based data in order to propose a series of key facts about individual aspects of the topic. The first section of the document is a summary of some of the general aspects concerning the general assessment of travelers who return home with potential infections. The main second section contains the key facts (causative agents, diagnostic procedures and therapeutic measures) associated with the major infectious syndromes affecting returned travelers [gastrointestinal syndrome (acute or persistent diarrhea); febrile syndrome with no obvious source of infection; localized cutaneous lesions; and respiratory infections]. Finally, the characteristics of special traveler subtypes, such as pregnant women and immunocompromised travelers, are described (AU)

En el mundo global, el conocimiento de las enfermedades infecciosas importadas es esencial en la práctica diaria, tanto para el microbiólogo-parasitólogo como para el clínico en enfermedades infecciosas que atiende a viajeros internacionales. Entre los destinos turísticos más visitados se encuentran muchos países tropicales o subtropicales, donde el riesgo de contraer una enfermedad infecciosa es más elevado. La SEIMC ha considerado pertinente la elaboración de un documento de consenso que sirva de ayuda tanto a médicos de Atención Primaria como a especialistas en Medicina Interna, Enfermedades Infecciosas y Medicina Tropical que atienden a viajeros que regresan con infecciones tras un viaje a zonas tropicales y subtropicales. Se han excluido de forma explícita los aspectos de prevención de estas y las infecciones importadas por inmigrantes, objeto de otros documentos de la SEIMC. Varios tipos de profesionales (clínicos, microbiólogos y parasitólogos) han desarrollado este documento de consenso tras evaluar los datos disponibles basados en la evidencia para proponer una serie de datos clave acerca de este aspecto. Inicialmente se revisan los aspectos generales acerca de la evaluación general del viajero que regresa con una potencial infección. En un segundo bloque se señalan los datos clave (agentes causales, procedimientos diagnósticos y medidas terapéuticas) de los síndromes infecciosos principales en el viajero que regresa (síndrome gastrointestinal (diarrea aguda o persistente), síndrome febril sin foco aparente, lesiones cutáneas localizadas e infecciones respiratorias). Finalmente se describen las características en viajeros especiales como la viajera embarazada y el viajero inmunodeprimido (AU)

Chlamydia trachomatis re-infection in Spain: A STI clinic-based cohort study / Reinfección por Chlamydia trachomatis en España: un estudio de cohorte en una Unidad de ITS

BACKGROUND: Chlamydia trachomatis (C. trachomatis) is the most frequently reported sexually transmitted infection (STI) in developed countries, but there is a lack data on its incidence and population dynamics in Spain. The objectives of this study were to estimate the incidence of C. trachomatis in patients seeking medical attention in an STI clinic with a defined population catchment area, to identify factors associated with this infection, and to explore differences between factors associated with new infections and re-infections. METHODS: A retrospective study was conducted on a cohort of patients from a STI clinic who underwent chlamydia testing at least twice between 2007 and 2015. RESULTS: Of the 2633 patients who met study selection criteria, 795 (30.2%) tested positive for C. trachomatis at baseline (baseline Chlamydia). The overall incidence was 7.97/100 person-years (95% CI: 7.2-8.8): 5.9/100 person-years (95% CI: 5.2-6.7) among patients testing negative for C. trachomatis at baseline, and 18.3 person-years (95% CI: 15.6-21.5) among those testing positive at baseline. In multivariate analysis, the factors independently associated with overall incidence were a history of infection with C. trachomatis in the previous 6 months (hazard ratio=3.6; 95% CI: 2.3-5.4), younger age (HR <20 vs ≥35 years=5.5; 95% CI: 3.2-9.5), male sex, 2 or more sexual partners in the previous month and year, and inconsistent condom use. CONCLUSIONS: Guidelines should be established for C. trachomatis in Spain, including recommendations on the need for follow-up and re-testing, independently of age. Though data concerning the optimal timing of re-testing are inconclusive, our findings support the establishment of a 3-6 month interval

INTRODUCCIÓN: Chlamydia trachomatis es la infección de transmisión sexual (ITS) más frecuentemente notificada en los países desarrollados, pero en España carecemos de información sobre su incidencia y su dinámica poblacional. Nuestros objetivos han sido estimar la incidencia de C.trachomatis en los pacientes de una clínica de ITS con una población de referencia definida, identificar factores asociados con ella y evaluar diferencias entre los factores asociados con las nuevas infecciones y las reinfecciones. MÉTODOS: Cohorte retrospectiva de pacientes de una Unidad de ITS con pruebas diagnósticas para Chlamydia en más de una ocasión entre 2007 y 2015. RESULTADOS: De los 2.633 pacientes que cumplieron los criterios de inclusión en el estudio, 795 (30,2%) tuvieron un resultado positivo de C.trachomatis en el episodio basal (Chlamydia basal). La incidencia global fue de 7,97/100 años-persona (IC 95%: 7,2-8,8): 5,9/100 años-persona (IC 95%: 5,2-6,7) entre los pacientes con chlamydia basal negativa y 18,3 años-persona (IC 95%: 15,6-21,5) entre aquellos con chlamydia basal positiva. En los análisis multivariantes, los factores asociados independientemente con la incidencia global fueron haber padecido otra infección por C.trachomatis en los últimos 6meses (hazard ratio [HR] = 3,6; IC95%: 2,3-5,4), menor edad (HR < 20 vs ≥ 35 = 5,5; IC95%: 3,2-9,5), ser hombre, 2 o más parejas en el último mes o en el último año y la utilización inconsistente del preservativo. CONCLUSIÓN: Son necesarias guías de práctica clínica para C.trachomatis en España que incluyan recomendaciones sobre la necesidad de seguimiento y re-cribado, independientemente de la edad. El periodo óptimo para repetir las pruebas no está establecido, nuestros resultados apoyan la implantación de un intervalo de 3-6 meses

[Immigration and HIV Infection. An approximation to parasitic and viral infections]. / Inmigración y VIH. Aproximación a las enfermedades parasitarias y virales.

Highly-active antiretroviral therapy is effective in reducing opportunistic infections in industrialized countries. However, opportunistic parasitic infections remain the leading cause of HIV-related mortality in developing countries. These infections can also affect HIV-positive immigrants residing in Spain, as well as HIV-infected patients traveling to low-income countries. In addition, immigrants often have viral infections caused by herpesvirus, papillomavirus and polyomavirus, which are closely related to risk behaviors and commercial sex. The present article reviews the characteristics of parasitic and viral infections in patients with HIV infection with the aim of improving understanding of this vulnerable population group.

Inmigración y VIH. Aproximación a las enfermedades parasitarias y virales / Immigration and HIV Infection. An approximation to parasitic and viral infections

El tratamiento antirretroviral de gran actividad ha resultado eficaz para reducir las infecciones oportunistas en países industrializados. Sin embargo, las infecciones parasitarias constituyen todavía la primera causa de mortalidad asociada a infección por el virus de la inmunodeficiencia humana (VIH) en países en desarrollo. Estas infecciones también pueden afectar a la población de inmigrantes que residen en España, así como a pacientes con infección por el VIH que viajan a países de baja renta per cápita. Por otro lado, los inmigrantes con frecuencia presentan infecciones causadas por herpesvirus, papilomavirus y poliomavirus que están íntimamente relacionadas con conductas de riesgo y la prostitución. En este artículo revisamos las características de las infecciones parasitarias y virales en pacientes con infección por el VIH, con el fin de mejorar el conocimiento de este grupo de población tan vulnerable
