BACKGROUND: 1-week proton pump inhibitor-based triple therapies are considered the most effective and convenient drug combinations for curing Helicobacter pylori infection. Short therapies, lasting less than 1 week have been investigated rarely. AIM: To assess the efficacy and tolerability of a 3-day lansoprazole triple therapy after 1 day of lansoprazole pre-treatment. METHODS: Seventy H. pylori-positive (rapid urease test and histology) patients received LAzT3 regimen (lanzoprazole 30 mg b.d. and azithromycin 500 mg o.m. for 3 days; tinidazole 2000 mg o.m. on day 1 and 1000 mg o.m. on days 2-3) after 1 day of lansoprazole pretreatment. Patients with active ulcer received lansoprazole 30 mg o.m. for an additional 4 weeks. Follow-up gastroscopy was carried out 4-6 weeks after completion of therapy. Eradication was defined as negative histology and rapid urease test. RESULTS: Four patients failed to attend the follow-up endoscopy. One patient complained of minor side-effects. H. pylori was eradicated in 57 of 66 patients suitable for evaluation, with a per-protocol cure rate of 86.3% (95%CI: 76-94%), and an intention-to-treat cure rate of 81.4% (95%CI: 70-90%). CONCLUSIONS: This new ultrashort triple therapy including lansoprazole, azithromycin and tinidazole seems to be effective in eradicating H. pylori. It is safe and well-tolerated, and may be taken into consideration as a valid alternative to the better known and widely used 1-week proton pump inhibitor-based triple therapies.

Abstract

BACKGROUND: 1-week proton pump inhibitor-based triple therapies are considered the most effective and convenient drug combinations for curing Helicobacter pylori infection. Short therapies, lasting less than 1 week have been investigated rarely. AIM: To assess the efficacy and tolerability of a 3-day lansoprazole triple therapy after 1 day of lansoprazole pre-treatment. METHODS: Seventy H. pylori-positive (rapid urease test and histology) patients received LAzT3 regimen (lanzoprazole 30 mg b.d. and azithromycin 500 mg o.m. for 3 days; tinidazole 2000 mg o.m. on day 1 and 1000 mg o.m. on days 2-3) after 1 day of lansoprazole pretreatment. Patients with active ulcer received lansoprazole 30 mg o.m. for an additional 4 weeks. Follow-up gastroscopy was carried out 4-6 weeks after completion of therapy. Eradication was defined as negative histology and rapid urease test. RESULTS: Four patients failed to attend the follow-up endoscopy. One patient complained of minor side-effects. H. pylori was eradicated in 57 of 66 patients suitable for evaluation, with a per-protocol cure rate of 86.3% (95%CI: 76-94%), and an intention-to-treat cure rate of 81.4% (95%CI: 70-90%). CONCLUSIONS: This new ultrashort triple therapy including lansoprazole, azithromycin and tinidazole seems to be effective in eradicating H. pylori. It is safe and well-tolerated, and may be taken into consideration as a valid alternative to the better known and widely used 1-week proton pump inhibitor-based triple therapies.
