Se presentó el caso de un paciente de 5 años atendido en consulta de Gastroenterología en el Hospital Pediátrico Docente Provincial Eliseo Noel Caamaño, de Matanzas, por presentar dolor abdominal, heces pastosas, náuseas y vómitos desde hacía un año. Llevó tratamiento con ranitidina, omeprazol y domperidona, sin mejoría clínica. Se realizó estudio coproparasitológico en muestras de heces fecales seriadas, con la presencia del Blastocystis hominis. Se indicó tratamiento con metronidazol, sin mejoría clínica, y posteriormente se indicó como alternativa la nitazoxanida. Se evaluó a los 15 días, sin sintomatología y con negativización de las heces fecales seriadas. Resulta frecuente el desconocimiento y la poca importancia que los profesionales sanitarios muestran ante esta infestación, aunque cada vez más se confirma la participación del parásito en manifestaciones clínicas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Blastocystis sp. is a frequent parasite in humans, identified in the laboratory in samples of fecal feces. The case of a 5-year-old patient is presented; he assisted the consultation of Gastroenterology in the Provincial Teaching Pediatric Hospital Eliseo Noel Caamaño in Matanzas, suffering abdominal pain, mash feces, nauseas and vomits for one year, and was treated with ranitidine, omeprazole and domperidone without clinical improvement. A coproparasitological study was carried out in serial fecal feces samples with the presence of Blastocystis hominis. Treatment with metronidazole was indicated without clinical improvement and them, as an alternative, nitazoxanide was indicated. He was evaluated at 15 days without symptoms and with negative serial fecal feces. The ignorance and the little importance that health professionals show towards this infestation are frequent, although more and more frequently it is confirmed the participation of the parasite in clinical manifestations.]]></p></abstract>
