Abstract

Two hundred and thirty-nine patients underwent colonoscopy for unexplained rectal bleeding. Local anorectal conditions were excluded by digital and proctosigmoidoscopic examinations and results of barium studies were negative for all patients. A cause for bleeding was found in 95 patients. Thirty-nine had adenomatous polyps, 24 had unrecognised inflammatory bowel disease, and most importantly 23 (10% of series) had carcinomas. Forty patients had diverticular disease, but nine of them were found to have an adenomatous polyp and four a carcinoma. Colonoscopy can contribute positively to the investigation and treatment of unexplained rectal bleeding and may prevent unnecessary laparotomy.

Cytomegalovirus colitis presenting as hematochezia and requiring resection.

Cytomegalovirus infection is one of the most prevalent viral infections affecting recipients of cardiac allografts. Of the various severe systemic manifestations, those in the gastrointestinal tract have a unique way of presenting, specifically in the colon where a process related to cytomegalovirus infection that involves all layers, with dilatation as a prominent clinical feature, has been suggested. We report herein a case of patient with a heart allograft who had severe episodes of rejection that responded to boosting doses of steroids. Because of persistent fever, diarrhea, hematochezia, and computed tomographic findings of the abdomen that showed a highly abnormal appearance of the ascending and transverse segments of the colon, this patient subsequently underwent celiotomy. The involved segment of the colon was found to have severe inflammation with mucosal necrosis; a subtotal colectomy was done. The abundant cytomegalovirus inclusions found in the vascular endothelium of the removed damaged segment of the colon suggest that cytomegalovirus may have been a causal factor in this form of colitis. The patient recovered uneventfully.

Increased HLA A1 and diminished HLA A3 in lymphocytic colitis compared to controls and patients with collagenous colitis.

Lymphocytic colitis is a newly described chronic diarrheal disorder. Although its etiology is unknown, the possibility has been raised that autoimmunity may play a role in both lymphocytic and collagenous colitis, a similar clinicopathologic illness. The frequencies of HLA class I and class II antigens were examined in 24 white patients with lymphocytic colitis and in 47 white patients with collagenous colitis. Frequencies in these two disorders were compared to control white populations and to each other. An increased frequency of HLA-A1 was noted in 16 of 24 lymphocytic colitis patients (66.6%) compared with 1089 of 3942 controls (27.6%) (P less than 0.005; relative risk 5.2). Furthermore, HLA-A3 was found in decreased frequency in lymphocytic colitis patients: 0 of 24 (0%) compared with 1017 of 3942 controls (25.8%) (P less than 0.05; relative risk 0.0). Collagenous colitis patients had no significant deviation from control frequencies of HLA antigens. In lymphocytic colitis, there was no significant increase in B8 or DR3 antigens, which are found in linkage disequilibrium with A1 and associated with many autoimmune diseases. Moreover, the frequency of autoimmune-associated class I HLA antigens was not increased in lymphocytic colitis. Statistically significant differences existed between lymphocytic and collagenous colitis in HLA-A1, A3, Bw6, and B7 antigen frequencies. The HLA patterns noted previously in other gastrointestinal disorders, including ulcerative colitis and Crohn's disease, were not apparent in lymphocytic or collagenous colitis. HLA typing provides further evidence that lymphocytic colitis is a distinct form of chronic intestinal inflammatory disease associated with HLA class I phenotypes.
