ABSTRACT
Intestinal coccidiosis in a 6-mo-old infant terminated fatally after 30 wk of continuous total parenteral nutrition, and proved refractory to treatment with antibiotics, hydrocortisone, and antimetabolic agents. Intestinal biopsies obtained at laparotomy revealed flattened mucosa infiltrated with coccidia at various stages of the parasites' life cycle. The course was characterized by severe diarrhea due to a cholera-like hypersecretion of intraluminal fluid. This case suggests that intestinal coccidiosis may be included among the small number of conditions responsible for authentic "intractable diarrhea of infancy."

The diagnoses which may be arrived at by examination of peroral small bowel mucosal biopsy specimens are presented. Celiac sprue, unclassified sprue (refractory sprue), infectious gastroenterititis, stasis syndrome and kwashiorkor have a severe mucosal lesion. Other clinical conditions are required to establish the diagnosis in these diseases. A number of diseases have specific diagnostic features. Included are Whipple's disease, abetalipoproteinemia, collagenous sprue, primary intestinal lymphoma, eosinophilic gastroenteritis, giardiasis, coccidiosis, strongyloidiasis, lymphangiectasis and the intestinal immunodeficiency diseases. Mucosal abnormalities may be present in other diseases but the diagnoses are usually made on other criteria than small bowel biopsy. These include vitamin B12 or folic acid deficiency, Crohn's disease, gastrinoma, acrodermatitis enteropathica, amyloidosis, chronic granulomatous disease, lipid storage diseases, histoplasmosis, capillariasis, cytomegalovirus infection, schistosomiasis and macroglobulinemia.
