[Erosive gastroduodenitis associated with Cryptosporidium in a patient with acquired immunodeficiency syndrome].

The occurrence of abdominal pain, vomiting, and diarrhea in patients with acquired immune deficiency syndrome has been attributed more frequently to enteropathogen organisms that invade the body in consequence of the immunologic unbalance of the host. Among several causes the cryptosporidiosis has been detected with some prevalence and its predominant localization was gastrointestinal tract, although other extra-intestinal sites have also been reported. In the present case the endoscopic examination established the diagnosis of erosive gastroduodenitis while the histological examination showed the presence of Cryptosporidium sp. in gastric and duodenal biopsy specimens. A proper etiological diagnosis in such cases is important for the choice of therapy.
