A 38-year-old man with AIDS and intractable large-volume diarrhea due to a cryptosporidial infection was successfully treated with intravenous octreotide, a somatostatin analogue. The volume of diarrhea, 10-12 liters with 8-13 movements per day, was reduced to three to four semi-formed to formed stools per day when the patient was treated with 400 micrograms intravenous octreotide daily. The patient's intravenous hyperalimentation was discontinued and he returned to oral feeding. He quickly regained his normal weight and has now resumed his normal activities. For those patients who cannot tolerate subcutaneous administration, intravenous octreotide therapy may not only be life-saving but may also markedly increase the quality of life. Roxithromycin, a macrolide antibiotic, was also administered to this patient with cryptosporidiosis but efficacy was not demonstrated.

Clinical observation suggests that the natural history of intestinal cryptosporidiosis in patients with acquired immunodeficiency syndrome varies greatly. The relation between clinical, small-bowel functional, and nutritional status and the intestinal distribution of the organism was studied in 41 patients who had acquired immunodeficiency syndrome and cryptosporidiosis and who had undergone both proximal small-bowel and colonic biopsies. Two patterns of enteric cryptosporidiosis were identified: severe clinical disease with malabsorption in patients with cryptosporidia in proximal small-bowel biopsy specimens (61% of cases) and less severe clinical disease in patients with cryptosporidia only in the colon or stool (39% of cases). Patients with cryptosporidia in proximal small-bowel biopsy specimens had small-bowel crypt hyperplastic villous atrophy, lamina propria inflammatory infiltrates, poorer D-xylose absorption, greater weight loss, and shorter survival and more often needed intravenous hydration or hyperalimentation. Patients with cryptosporidia in the small-bowel villi only had less severe disease than those with cryptosporidia in the small-bowel crypts. In conclusion, the anatomic distribution of intestinal cryptosporidia in patients with acquired immunodeficiency syndrome varies, and this variation may explain differences in clinical course. Cryptosporidial infection of the proximal small bowel correlates with mucosal injury, malabsorption, dehydration, weight loss, and shortened survival.
