A comparison of omeprazole and ranitidine for duodenal ulcer in South African patients. A multiracial study.

The study was a multicenter double-blind parallel-group comparison of omeprazole, a proton-pump inhibitor, with the H2-receptor antagonist, ranitidine, in 206 patients with duodenal ulcer. There were 145 men and 62 women of mixed racial origin with an average age of 40 years (range 19-76); 63 of them were white, 7 black, 135 coloured and 1 Asian. Each drug was given for four weeks and ulcer healing rate, symptom relief, and adverse events were recorded and compared between treatment groups. Patients received either 20 mg omeprazole once daily in the morning (N = 104) or ranitidine 300 mg once daily at night (N = 106). Healing rates were significantly higher in the omeprazole group than in the ranitidine group at both two weeks (80% vs 52%, P less than 0.001) and four weeks (95% vs 85%, P less than 0.05), using the "per protocol" approach, and these results were confirmed using the "intention to treat" approach. Omeprazole-treated patients reported significantly less daytime epigastric pain (P = 0.02) and heartburn (P = 0.04) after two weeks than ranitidine-treated patients. By four weeks, there were no significant differences in symptom reporting between groups. Both treatments were well tolerated, and there were no serious adverse events.

Inflammatory bowel disease in Cape Town, 1975-1980. Part I. Ulcerative colitis.

Previously documented and new patients with ulcerative colitis seen between 1975 and 1980 in the Gastro-intestinal Clinic of Groote Schuur Hospital were studied to establish the local incidence and clinical features of this disease. There were 220 patients and the mean follow-up was 7,7 +/- 0,4 years. Sixty per cent of patients were White, 37% Coloured and 3% Black. The incidence for the Coloured and White population was calculated to be 1,3 and 2,4/100 000 per year during 1970-1974 and 1,6 and 2,1/100 000 per year during 1975-1980, respectively. In Jews the rates were 8,5 and 10,4/100 000 per year for the two periods. Insufficient data are available to calculate an incidence for the Black population. The disease was limited to less than 15 cm above the anus in 14% of patients, to the rectosigmoid colon in 45%, and to the rest of the colon in 40%. Although the severity of symptoms was related to the extent of disease, 22% of patients with extensive colitis had mild symptoms, while 15% with disease limited to the rectum had severe symptoms. The clinical features were similar in the White and Coloured population groups. A total colectomy was performed on 20% of patients with extensive colitis; in 2% the disease was complicated by colonic carcinoma.

Inflammatory bowel disease in Cape Town, 1975-1980. Part II. Crohn's disease.

Patients with Crohn's disease seen in the Gastro-intestinal Clinic of Groote Schuur Hospital between 1975 and 1980 were studied to establish the incidence and clinical features of this disease. There were 117 patients and the mean (+/- SEM) follow-up was 6,1 +/- 0,5 years. Of these patients 72% were White, 37% Coloured and 1% Black. The incidence for the Coloured and White population groups was calculated to be 0,4 and 0,9/100 000 per year during 1970-1974 and 1,3 and 1,2/100 000 per year during 1975-1980 respectively. In Jews the rates were 5,0 and 7,2/100 000 per year for the two periods. Insufficient data are available to calculate an incidence for the Black population. The disease involved the ileum in 39%, the colon in 17% and both areas in 44% of patients. At presentation 18% of patients had mild, 37% moderate, and 45% severe disease. The severity of symptoms was not related to the extent of the disease. A peri-anal fistula was present in 24% of patients. There was no difference in clinical features between the different population groups. Surgical resection had been performed in 50% of patients and 29% of these had had two or more resections. The surgical rate in the ileitis group was 63%, in the ileocolitis group 49% and in those with colitis 20%.

Mesenteric ischaemia--a diagnostic triad?

An elderly man with ischaemic heart and peripheral vascular disease presented with a 3-month history of increasingly severe postprandial epigastric pain, nausea, vomiting, diarrhoea and weight loss, associated with gastroscopic evidence of superficial antral ulceration and discoloration. The patient died shortly after admission to hospital. Autopsy showed evidence of mesenteric vascular disease and ischaemic bowel. The literature on chronic mesenteric ischaemia is briefly reviewed, and the role of arteriography is discussed.
