Monotherapy or Polychemotherapy in the Treatment of Campylobacter pylori-Related Gastroduodenal Disease

Abstract

Three pilot studies were performed to evaluate the efficacy of bismuth subsalicylate (BSS) and nitrofurantoin to eradicate Campylobacter pylori colonization in man. Nitrofurantoin 3 × 100 mg capsules for 10 days did not clear C. pylori in any of 13 patients, and neither did the combination of BSS and nitrofurantoin suspension (0/6 patients). Immediately after high dose BSS therapy 3 × 900 mg for 28 days, 8/17 patients (47%) had negative cultures and rapid urease tests. There was recrudescence in 5 out of 6 patients so far submitted to follow-up investigations, giving a best possible outcome estimate of 18% and a worst possible eradication rate of 6% in this study. Preliminary data indicate that triple therapy may be a more effective option, but doubts remain as to whether the puristic therapeutic goal of complete bacterial eradication can be safely and effectively achieved with presently available drugs.
