ABSTRACT

La diarrea del viajero (DV) es la complejidad más común y su repercusión varía en función de muchas variables: edad, lugar de destino, estación del año, tipo de residencia, origen del viajero y, por supuesto, la dieta durante el viaje, en definición es la emisión de heces sueltas tres o más veces al día, se adquiere mayormente al consumir alimentos y bebidas contaminados con patógenos que ocasionen diarrea. A nivel mundial, las causas más comunes de DV son dos patotipos de Escherichia coli (enterotoxigénica y enteroagregativa) y Campylobacter, aunque existen variaciones significativas según el área geográfica visitada. Algunos autores han detectado la presencia de diarrea en más de la mitad de los viajeros a países en vías de desarrollo. Se realizó un estudio descriptivo de corte transversal en 15 hospitales centinelas de la zona 9 del Sistema de Vigilancia de la resistencia antimicrobiana, en la provincia de Pichincha Quito, Ecuador entre enero 2019 a enero 2020, con el objeto de caracterizar los eventos de DV. 517 registros, solo en 298 se asento la procedencia, pudiendo atribuirse a ese 42,34% la procedencia por nacionalidad, se estimó que 108 casos presentaron infección mixta de al menos una bacteria y otro tipo de agresor, lo que representa 36,24%, siendo el agente causal principalmente involucrado ETEC, seguida de E. coli H7:O157 (N=60)(AU)


Traveler's diarrhea (DV) is the most common complexity and its impact varies depending on many variables: age, place of destination, season of the year, type of residence, origin of the traveler and, of course, the diet during the trip, In definition, it is the emission of loose stools three or more times a day, it is acquired mostly by consuming food and beverages contaminated with pathogens that cause diarrhea. Worldwide, the most common causes of DV are two Escherichia coli pathotypes (enterotoxigenic and enteroaggregative) and Campylobacter, although there are significant variations depending on the geographic area visited. Some authors have detected the presence of diarrhea in more than half of the travelers to developing countries. A descriptive cross-sectional study was carried out in 15 sentinel hospitals in zone 9 of the Antimicrobial Resistance Surveillance System, in the province of Pichincha Quito, Ecuador between January 2019 and January 2020, in order to characterize VD events. 517 records, only in 298 the origin was established, and that 42.34% can be attributed the origin by nationality, it was estimated that 108 cases presented mixed infection of at least one bacterium and another type of aggressor, which represents 36.24% , the causative agent being mainly involved ETEC, followed by E. coli H7: O157 (N = 60). Likewise, ETEC is responsible for the greatest severity in clinical pictures, being responsible for 50.00% of the cases in this category(AU)

ABSTRACT

Introducción: La diarrea del viajero es causa frecuente de hospitalización en turistas internacionales. Objetivo: Describir las características sociodemográficas y clínico-epidemiológicas de los pacientes adultos ingresados por diarrea del viajero en la Clínica Internacional de Trinidad durante los años 2015 al 2017. Métodos: Estudio descriptivo de los 699 pacientes adultos con diarrea del viajero que requirieron de ingreso en el periodo de estudio. Se revisaron sus historias clínicas para analizar la frecuencia en que estuvieron presentes algunas variables sociodemográficas y clínico-epidemiológicas. Para analizar los datos se utilizó la estadística descriptiva con distribución de frecuencias y porcentajes. Resultados: El grupo etario entre 19 y 40 años tuvo un 60,52 por ciento de pacientes afectados; el 58,23 por ciento en el sexo femenino, con una incidencia mayor en los meses de julio (12,88 por ciento) y febrero (12,44 por ciento). Los viajeros procedentes de países europeos representaron el 76,97 por ciento ; el 74,96 por ciento se hospedó en casas particulares. El 1,85 por ciento de los afectados presentaba antecedentes de enfermedad gastrointestinal; el 76,11 por ciento requirió de 1 a 6 h de observación, con deshidratación leve (59,66 por ciento) y moderada (21,75 por ciento). El vómito y las náuseas se presentaron en el 58,37 por ciento de los pacientes y en el 60,73 por ciento la causa no fue precisada. Conclusiones: Las variables sociodemográficas y clínico-epidemiológicas seleccionadas permitieron describir características de los pacientes adultos ingresados por diarrea del viajero. Se recomienda profundizar en el estudio para contribuir a su prevención y optimizar la atención(AU)


Introduction: Traveler's diarrhea is a frequent cause of hospitalization of international tourists. Objective: Describe the sociodemographic and clinical-epidemiological characteristics of adult patients admitted for traveler's diarrhea to Trinidad International Clinic in the period 2015-2017. Methods: A descriptive study was conducted of the 699 adult patients with traveler's diarrhea who required hospitalization in the study period. The patients' medical records were reviewed to analyze the frequency of some sociodemographic and clinical-epidemiological variables. Data analysis was based on descriptive statistics with frequency and percentage distribution. Results: 60.52 percent of the patients affected were in the 19-40 years age group, 58.23 percent were female, and the highest incidence was observed in the months of July (12.88 percent) and February (12.4 4 percent ). Travelers from European countries represented 76.97 percent, and 74.96 percent were staying in private dwellings. Of the patients affected, 1.85 percent had a history of gastrointestinal disease; 76.11percent required 1-6 hours of observation; dehydration was mild in 59.66 percent and moderate in 21.75 percent. Vomiting and nausea were present in 58.37 percent of the patients; in 60.73 percent the cause was not determined. Conclusions: The sociodemographic and clinical-epidemiological variables selected made it possible to characterize the adult patients admitted for traveler's diarrhea. Further research is recommended to contribute to the prevention this disease. Further research is recommended to contribute to the prevention this disease and optimize care(AU)

ABSTRACT

Human infection by Cyclospora cayetanensis, namely cyclosporiasis, can cause a wide range of symptoms in immunocompetent patients, from mild to severe diarrhea. Immunocompromised patients can present with chronic diarrhea and it has been recognized as a cause of traveler's diarrhea. We report three patients who traveled from Chile to Peru, who presented upon returning with prolonged traveler's diarrhea. A literature review about cyclosporiasis is presented, with emphasis on the clinical, epidemiological, diagnostic and therapeutic aspects of this disease.
