|Abstract:||A 9-year-old boy with a 5-year history of severe protracted diarrhea requiring home parenteral nutrition and a 1 year history of abnormal liver function tests was admitted for duodenal, rectal, and liver biopsy. Duodenal biopsy results showed mild villus blunting, a mild lymphocytic infiltrate, and absent goblet cells. Paneth cells and endocrine cells could not be identified. Review of several previous biopsies showed an almost total absence of goblet cells by light microscopy. Anti-goblet cell antibodies of the immunoglobulin (Ig)G class were shown by immunofluorescence with a titer of 1:512. Histological examination of rectal mucosa also showed a total lack of goblet cells, orderly surface epithelial cells, and infiltration of the colonic crypts by lymphocytes. Immunoperoxidase staining of rectal mucosa showed increased numbers of lymphocytes with an excess of CD3+, CD45RO+ T cells, and increased numbers of B cells labeling with B1 and L26. Increased numbers of CD25+ (activated) lymphocytes were also observed. HLA/DR expression was striking and observed in both the crypt and surface enterocytes, as well as in the lamina propria. Immunological assessment of the patient showed an inverted CD4/CD8 ratio and IgA/IgG4 deficiency. The liver biopsy and radiological investigation were in keeping with chronic sclerosing cholangitis. Although a slight and transient improvement in histological appearances was observed with prednisolone there was no significant improvement of diarrhea. Trials of azothiaprine and oral cyclosporin did not result in clinical or histological improvement.|
