title: [Immunopathology of ulcerative colitis and granulomatous colitis (author's transl)].
abstract: There is no convincing evidence as yet for a key role of immunological processes in the pathogenesis of unspecific colitis. However clinical findings as well as immunological data do support the hypothesis that immune reactions are involved primarily or secondarily in the pathogenesis and the clinical course of ulcerative colitis and granulomatous colitis. In such patients a specific adaptation of humoral and cell-bound immune reactions against antigenic material from the colon and other tissues has been found in peripheral blood, lymphatic tissue and bowel wall. In this context it seems to be especially noteworthy, that lymphocytes taken from patients with colitis lead to disintegration of colon epithelial cells in vitro. This cytotoxic effect of the lymphocytes is lost after colectomy or remission of the disease. Ulcerative and granulomatous colitis do have many clinical and immunological peculiarities in common. This makes one think, that possibly the same noxious factors induce differential local reactions because of different hereditary disposition.
