[New simplified regimen for Helicobacter pylori eradication achieves high effectiveness. Prospective study in a private clinic in Lima, Peru].

OBJECTIVE: To determine the effectiveness of two new therapeutic regimes for Helicobacter pylori versus triple therapy that includes a proton pump inhibitor, amoxicillin and clarithromycin.

MATERIALS AND METHODS: prospective study, non-randomized, in a private Hospital in Lima, Peru. Patients with biopsy and/or rapid ureasa test proven Helicobacter pylori infection received one of the three therapeutic regimens and were followed with a urea breath test 1 to 6 months upon completion of therapy.

RESULTS: Triple therapy achieved eradication in 49/68 of cases (71.2%); quadruple therapy (doxycycline + metronidazole + bismuth + esomeprazole) in 52/62 (83.9%), and the simplified regimen with doxycycline + furazolidone + bismuth, obtained success in 79/83 of cases (95.2%). Statistically significant difference with p<0.005 and p<0.05 respectively.

CONCLUSION: Triple therapy against Hp does not achieve acceptable effectiveness in our institution. This highlights the need to look for new therapeutic options, being the simplified regime (doxycycline, furazolidone and bismuth) used in the current study a good option, requiring further studies for validation.
