Clinical investigation of 10 patient with amebic dysentery

Abstract

Data were obtained in 10 patients with amebic dysentery at Osaka Socio-Medical Center hospital during the period from April 1985, to April 1989. All of the patients were male, and their average age was 41 years old. In the past history, all of them had never gone to foregin countory, and 7 patients had the habit of homosexual love. In the serological test, positive rate of antiamebic antibody was 100% (6/6) by agar gel diffusion, that of antibody of Toreponema pallidum was 60% (6/10) by TPHA, but anti AIDS antibody was not detected (0/3) by HIV. Detectability of Entoamoeba hystolitica was 70% (7/10) in stool, 50% (2/4) in liver abscess, 25% (1/4) in biopsied specimens of rectal mucosa. Then, we fund that the serological test for antiamebic antigen was useful for diagnosis of this disease, and suspected that homosexual contact contributed to the infection of E. hystolitica. © 1990, The Japanese Society of Gastroenterology.
