demonstration of isospora belli by acid-fast stain in a patient with acquired immune deficiency syndrome.isospora belli, like cryptosporidium sp., a sporozoan parasite of the small intestine, has been isolated from both immunodeficient and immunologically normal persons. in immunocompetent persons the infection may be asymptomatic; it frequently causes mild and self-limited diarrhea. the spectrum of the disease in persons with acquired immune deficiency syndrome is not well established. i. belli did not stain well with the methods usually used for intestinal protozoa and was difficult to see unstai ...19846208216
persistent diarrhoea in zairian aids patients: an endoscopic and histological determine the aetiology of persistent diarrhoea in african patients with acquired immunodeficiency syndrome (aids), 42 patients with human immunodeficiency virus (hiv) and persistent diarrhoea were enrolled in a microbiological, endoscopic, and histological study. cryptosporidium was the intestinal parasite most often identified (30%); isospora belli was found in 12% of the patients. histological examination of the duodenal mucosa showed a non-specific inflammatory reaction in a significantly ...19883220308
isospora infection in a homosexual man.a case of isospora belli in a homosexual male is described. the procedures used for recovery and staining the cyst stages of isospora are included.19854028665
[cd4+ lymphocytes and opportunistic infections and neoplasms in patients with human immunodeficiency virus infection].the cd4+ lymphocytes are the principal target cell for the human immunodeficiency virus (hiv). their depletion originates a very severe cell immunosuppression, which conditions the appearance of opportunistic infections and neoplasms characteristic of aids. the aim of this study was to evaluate whether there is a relation between the degree of cell immunosuppression and the type of opportunistic infections and neoplasms which these patients develop in spain.19947646597
[diarrhea and acquired immunodeficiency syndrome in the tropics (tropical aids). the place of digestive endoscopic examinations in diagnosing opportunistic infections].a.i.d.s. has revealed some parasitic, microbiotic, mycotic or viral diseases causing diarrhea or has given a revival of interest to them. so are cryptosporidium, isospora belli, salmonella typhi murium, cytomegalovirus. some easy techniques lead to the diagnosis of some pathogenic agents, such as parasitologic diagnosis of cryptosporidium. some other pathogenic agents call for a biopsy in view of an histopathology test: it is the case of cytomegalovirus of which the diagnosis is stated positivel ...19873670029

isospora belli enteritis in three homosexual men.isospora belli is an uncommon cause of diarrhea in man. like the closely related cryptosporidium, the organism causes disease that may be more severe and chronic in patients with underlying immune deficiency states. we describe three male homosexuals with isospora enteritis. each had several months of diarrhea. all three patients had lymphopenia and two had profound t cell helper-suppressor ratio reversal. in addition, two of the patients admitted to oral-anal contact, a practice associated with ...19846507724

[digestive involvements in human immunodeficiency virus infection].dysphagia or odynophagia occurs in an estimated 21% of patients with human immunodeficiency virus infection. a causal agent can be identified in 60-90% of the cases and generally can be successfully eradicated. oesophageal candidosis, the predominant disorder, usually responds to nitrate derivatives and amphotericine b after a 10 to 15 day cure. ulcerations of the oesophagus is the second major cause of dysphagia in these patients and result from cytomegalovirus and herpes simplex infections or ...19957899394
diarrhoea and malabsorption in acquired immune deficiency syndrome: a study of four cases with special emphasis on opportunistic protozoan infestations.chronic diarrhoea is frequent in acquired immune deficiency syndrome (aids) but has been poorly investigated so far. we report four patients with aids in whom diarrhoea and malabsorption were outstanding features, and who underwent extensive digestive investigations. diarrhoea was a presenting symptom in all subjects and was of secretory type in three of them. d-xylose and vitamin b12 were malabsorbed in all cases; steatorrhea was found in the two patients who could ingest significant amounts of ...19854038492

[incidence and clinical aspects of intestinal coccidiosis in a tropical medicine practice].the microscopic investigation of 3 500 faecal samples with a method of concentration combining the ether treatment and flottation, has allowed to spot 5 cases (out of 700) of isosporosis (isospora belli) among subjects coming all from the tropical area and showing an occasionally serious symptomatology which has been treated by tinidazole. besides 2% samples were infested by sarcocystis hominis. the subjects affected were also from tropical origin, but did not present clinical disorders directly ...19806784940
