RESUMEN
Resumen

Introducción:

La infección por Cystoisospora belli es una de las causas más frecuentes de diarrea acuosa en pacientes con infección por VIH y ocasiona altas tasas de morbilidad y mortalidad.

Métodos:

Se realizó un estudio retrospectivo en pacientes infectados con VIH y diarrea por C. belli. Características clínicas y de laboratorio fueron recolectadas mediante el análisis de historias clínicas.

Resultados:

Se identificaron siete casos. Cuatro presentaron diarrea recurrente a pesar de recibir profilaxis secundaria con cotrimoxazol y tratamiento específico, dos de los cuales tuvieron buena respuesta viral e inmunológica al tratamiento anti-retroviral de gran actividad (TARGA) al momento del diagnóstico y tratamiento antiparasitario. Mientras que, los tres restantes no recibían profilaxis, tampoco TARGA (dos de ellos), pero respondieron bien al tratamiento.

Conclusiones:

C. belli es causa importante de diarrea en pacientes VIH con TARGA y profilaxis, pudiendo tener distinta evolución clínica. Sugerimos que la infección persistente puede ser debido al fallo farmacológico por causas intrínsecas o extrínsecas al parásito, o a defectos en la restauración del sistema inmune intestinal, o ambos.
ABSTRACT

Introduction:

Cystoisospora belli infection is one of the most important causes of watery diarrhea in patients with HIV and causes high rates of morbidity and mortality.

Methods:

A retrospective study was conducted in patients with HIV and diarrhea by C. belli. Clinical and laboratory characteristics were collected by analyzing clinical records.

Results:

Four had recurrent diarrhea despite receiving secondary prophylaxis with cotrimoxazole and specific treatment, two of which had a good viral and immunological response to highly active antiretroviral therapy (HAART) at the time of diagnosis and antiparasitic treatment. While the remaining three did not receive prophylaxis, neither did HAART (two of them), but they responded well to treatment.

Conclusions:

C. belli is an important cause of diarrhea in HIV patients on HAART and prophylaxis, being able to have different clinical evolution. We suggest that persistent infection may be due to drug failure by intrinsic or extrinsic to the parasite causes, or to defects in restoration of the intestinal immune system, or both.
