Campylobacter pylori and gastroduodenal ulcer disease. A prospective study in a Swedish population.

In a consecutive prospective series of 208 Swedish primary peptic ulcer patients, 146 gastric, 55 duodenal and 7 in both sites, gastroduodenitis was found in 97.6% of the cases. The mucosal inflammation was associated with CP in 87% and 91% of the gastric and duodenal ulcer cases respectively. No significant correlation was found between CP colonisation and the type or severity of mucosal inflammation. Gastric metaplasia was present in only 8% of 48 bulbar ulcer cases. Ulcer healing and eradication of CP was achieved in 52% of patients treated with bismuth subnitrate in combination with erythromycin or according to the triple approach.
