Cryptosporidium spp. es un protozoario productor de diarrea. Los pacientes inmunocomprometidos pueden desarrollar formas clínicas graves y persistentes. Se describen las características de pacientes con enfermedad de base asociada a inmunosupresión (EAI) con infección por Cryptosporidium spp. (IC) atendidos en un hospital pediátrico referencial de Argentina entre los años 2018 y 2023. Se analizaron datos demográficos, EAI, características de la diarrea y coinfecciones. Se incluyeron 30 pacientes con EAI e IC. La mayoría registró trasplante de órgano sólido, neoplasia hematológica e inmunodeficiencia primaria. Dieciocho presentaron diarrea persistente al momento del diagnóstico. Seis pacientes registraron coinfecciones. Se debe considerar la criptosporidiosis en el diagnóstico diferencial de enfermedad diarreica aguda o persistente en niños con distintos tipos de EAI, como el trasplante de órgano sólido, neoplasias hematológicas e inmunodeficiencias primarias.
Cryptosporidium spp. is a diarrhea-causing protozoan. Immunocompromised patients may develop severe and persistent clinical forms. Here we describe the characteristics of patients with an underlying disease associated with immunosuppression (DAI) and Cryptosporidium spp. infection seen at a referral children’s hospital in Argentina between 2018 and 2023. Demographic data, DAI, diarrhea characteristics, and co-infections were analyzed. A total of 30 patients with DAI and cryptosporidiosis were included. Most of them had undergone a solid organ transplant, had a hematologic neoplasm, or primary immunodeficiency. Persistent diarrhea was observed in 18 patients at the time of diagnosis. Co-infections were recorded in 6 patients. Cryptosporidiosis should be considered in the differential diagnosis of acute or persistent diarrhea in children with different types of DAI, such as solid organ transplant, hematologic neoplasms, and primary immunodeficiencies.
