Primary tuberculous granulomatous esophagogastro-duodenitis: a report of a case.

Primary upper gastro-intestinal tuberculosis is a very rare disease. We report the case of a 25-year-old man who presented with a febrile illness and non-specific gastro-intestinal symptoms. The upper gastro-intestinal X-rays showed a normal esophagus and non-specific changes of the stomach and duodenum.

Malakoplakia of the colon and recurrent colonic strictures in a patient with primary hypogammaglobulinemia: an association not previously described.

A nine-year old boy with primary hypogammaglobulinemia and recurrent colonic strictures who developed malakoplakia of the colon is reported on. Such an association has not been reported previously. The development of colonic strictures is not considered a gastrointestinal manifestation of hypogammaglobulinemia.

Impaired concanavalin A-inducible suppressor T-cell activity in active alcoholic liver disease.

To examine the possible contribution of cellular immunoregulatory mechanisms to the pathogenesis and progression of alcoholic liver diseases, suppressor T-cell function was evaluated in patients with severe active or inactive alcoholic liver disease and compared with normal control subjects. Suppressor T-cell activity after in vitro induction by concanavalin A or other T cell-mediated immune reactions was then assessed. T-cell interactions studied included the proliferative responses of both autologous or allogeneic responding peripheral blood mononuclear cells to T-cell mitogens and to allogeneic cells.
