RESUMO
OBJECTIVE: The association between cryptosporidiosis and persistent diarrhea has been studied in many countries. The aim of this study was to verify the incidence of this parasite in children with persistent diarrhea. Children infected or not with protozoan cryptosporidium were compared in relation to laboratory and clinic analysis.METHODS: Retrospective study in 70 inmate suckling at pediatrics hospital due persistent diarrhea, younger than 2 year, negative HIV, and other causes of diarrhea were ruled out. The duration of diarrhea, hospitalization, clinic modifications, preceding history of diarrhea, nutrition, d-xilosis and diet management were appraised.RESULTS: Criptosporidium sp was founded in 14 (20%) sucking and it was more frequent between children younger than 3 months (13/57, 23%). The duration of hospitalization and diarrhea were similar in both. Malnutrition was been present in 91.5% of patients, 13/14 of infected cryptosporidium children and 51/56 of not infected. The diet management was similar in both. There was a tendency to underdose xilosis of infected patients; mainly at the first year of life (15.9 +/- 8.2 and 33.8 +/- 19.9 p=0.007). CONCLUSION: Cryptosporidiosis is frequent in children with persistent diarrhea. Nevertheless, the infected patients did not differ of others if we consider theirs clinics, prognosis and therapeutics characteristics.
