title: [Ulcerative colitis caused by Histoplasma capsulatum in a patient with the acquired immunodeficiency syndrome].
abstract: The authors report a case of ulcerative colitis due to Histoplasma capsulatum in a previously healthy 35 year-old french geologist with acquired immune deficiency syndrome (AIDS). Gomori-Grocott and PAS stains and indirect immunofluorescence revealed Histoplasma capsulatum in colonic biopsies. The search for LAV antibody was positive. T-lymphocyte analysis revealed 10/mm3 OKT4 with OKT4/OKT8 ratio of 0.16. Histoplasmosis should be considered in subjects with ulcerative colitis according to the epidemiological context. In patients with AIDS relapses after discontinuation of treatment are to be expected and suppressive therapy with an imidazole derivative should probably be continued indefinitely.
