ABSTRACT
INTRODUCTION: The treatment and diagnosis of chronic diarrhea in the immunocompromised patient depends on the ability to rapidly detect the etiologic agents. AIMS: Our aim was to evaluate the results of the FilmArray® gastrointestinal panel in patients newly diagnosed with HIV infection that presented with chronic diarrhea. MATERIAL AND METHODS: Utilizing nonprobability consecutive convenience sampling, 24 patients were included that underwent molecular testing for the simultaneous detection of 22 pathogens. RESULTS: In 24 HIV-infected patients with chronic diarrhea, enteropathogen bacteria were detected in 69% of the cases, parasites in 18%, and viruses in 13%. Enteropathogenic Escherichia coli and enteroaggregative Escherichia coli were the main bacteria identified, Giardia lamblia was found in 25%, and norovirus was the most frequent viral agent. The median number of infectious agents per patient was three (range of 0 to 7). The biologic agents not identified through the FilmArray® method were tuberculosis and fungi. CONCLUSIONS: Several infectious agents were simultaneously detected through the FilmArray® gastrointestinal panel in patients with HIV infection and chronic diarrhea.
ABSTRACT
Las carbapenemasas son uno de los mecanismos enzimáticos de resistencia antimicrobiana, que compromete la mayor parte de los antibióticos betalactámicos. Por lo general, su producción se debe al uso indiscriminado de antimicrobianos. A nivel mundial, la expansión de este mecanismo de resistencia es inminente y las medidas de control son limitadas. Con el objeto de discutir los problemas relacionados a este mecanismo emergente de resistencia, reportamos un caso de Klebsiella pneumoniae productora de carbapenemasas en Huancayo, la Región de la Sierra Central de Perú.
Carbapenemases are one of the major mechanisms of antimicrobial resistance, usually due to the indiscriminate use of antibiotics. The expansion of this mechanism of resistance at world level is imminent and control measures are limited. In the region of the Central Sierra of Peru - Huancayo, we report a case of carbapenemase-producing Klebsiella pneumoniae, with the purpose of discussing the problems related to this emerging mechanism of antibiotic resistance.
