PG - 157-62 AB - AIM: The combination of a proton pump inhibitor (PPI) or ranitidine-bismuth-citrate (Rbc) and two antibiotics for 7-10 days are, at present, the preferred treatments in Helicobacter pylori eradication. However, therapies for fewer than 7 days have been scarcely evaluated and it is unknown whether the length of treatment can be shortened, without a lost of efficacy, if three instead of two antibiotics are used. The aim of our study was to evaluate the efficacy of Rbc plus three antibiotics for only 5 days in H. pylori eradication. METHODS: We prospectively studied 80 patients (34% duodenal ulcer, 66% functional dyspepsia) infected by H. pylori. At endoscopy, biopsies were obtained for histological study and rapid urease test, and a 13C-urea breath test was carried out. Urea breath test was repeated 4 weeks after completing eradication treatment with Rbc [400 mg twice a day (bid)], amoxicillin (1 g bid), clarithromycin (500 mg bid) and metronidazole (500 mg bid). All drugs were administered together after breakfast and dinner for 5 days only, and no treatment was administered thereafter. Compliance with therapy was determined from the interrogatory and the recovery of empty envelopes of medications. RESULTS: In 79 out of the 80 patients, H. pylori eradication success or failure was assessed after therapy (one patient was lost from follow-up). All but one of these 79 patients took all the medications (one patient stopped treatment on the day 3 due to nausea/vomiting). Per protocol eradication was achieved in 72/78 (92%; 95% CI, 84-96%) and in 72/80 (90%; 81-95%) by intention-to-treat. Therapy was more effective in patients with duodenal ulcer than in those with functional dyspepsia [100% (87-100%) vs. 85% (73-92%) by intention-to-treat; p <.05]. Adverse effects were described in ten patients (12%), and included the perception of a metallic taste (eight patients), nausea/vomiting (two patients, one of them abandoned the treatment due to this), and diarrhea (two patients). CONCLUSION: The combination of Rbc, amoxicillin, clarithromycin and metronidazole for only 5 days represents a promising therapy for H. pylori infection, due to its high efficacy, simple posology, low cost and excellent tolerance.
