Efficacy of sequential therapy versus standard triple therapy versus quinolone-based triple therapy for eradication of Helicobacter pylori infection

ABSTRACT

Background: Helicobacter pylori colonization is a risk factor for Adenocarcinomas of the distal (noncardia) stomach. The presence of Helicobacter pylori is strongly associated with primary gastric lymphoma. The urea breath test, the stool antigen test, and biopsy-based tests can all be used to assess the success of treatment. Helicobacter pylori is susceptible to a wide range of antibiotics in vitro, monotherapy is not usually successful, probably because of inadequate antibiotic delivery to the colonization niche. Current regimens consist of a PPI or H2 blocker, bismuth citrate and two or three antimicrobial agents given for 7-14 days. Research on optimizing drug combinations to increase efficacy continues. Efficacy of Sequential Therapy versus Standard Triple Therapy versus Quinolone-based Triple Therapy for eradication of Helicobacter pylori infection is done in this study.Methods: This study had been conducted on 150 patients divided into three groups randomly 50 Patients each and were treated with Sequential, Standard and Quinolone based triple therapy respectively. Patients were followed up no sooner than four weeks of completing therapy by rapid urease test to confirm eradication.Results: There was no significant difference with regards to presence of GERD, Gastric Ulcers, Duodenal Ulcers (p value>0.05) except for presence of erosive gastritis which was significantly higher in patients in quinolone group (p value<0.05). The eradication rate was 90%, 86%, 82% in Sequential therapy group, Triple therapy group and Fluroquinolone group respectively. However, there was no statistically significant difference in eradication rates in these groups (p value>0.05).Conclusions: Sequential therapy group had better eradication rates (90%) as compared to standard triple therapy group (86%) and fluroquinolone therapy group (82%) but results were not statistically significant when all three groups were compared together.
