Efficacies of Reverse Hybrid Therapy in Eradication of Helicobacter pylori Infection

ABSTRACT

Introduction: Because the prevalence of antibiotic resistancemarkedly increases with time worldwide, anti-H. pyloritreatment is continuing to be a great challenge for physiciansin clinical practice. Eradication of H. pylori infection markedlychanges the natural history of peptic ulcer in patients withduodenal or gastric ulcer. Most peptic ulcers associated withH. pylori infection are curable. Aim of present study was tostudy the efficacies of 14 days ‘ Reverse Hybrid Therapy’ inH.pylori positive G.I.patients.Material and methods: 100 H.pylori positive patients withupper G.I. complaints who underwent upper GI endoscopywere included in the study. H.pylori infection was documentedby at least 2 positive results of Rapid Urease Test. Subjectswith any of the following criteria were excluded from thestudy. 1. Previous eradication therapy 2. Allergy to anyantibiotic used in study. 3. Co- existence of any serious illness.4. Pregnancy or lactating women 5. Previous gastrectomy6. Use of antibiotics within last 4 week. Detailed medicalhistory and demographic details of the patients were recorded.Routine haematogical tests and USG was done. Patients weregiven 14 days dual therapy ie quadruple regimen (proton pumpinhibitor + amoxicillin + clarithromycin + metronidazole) forfirst 7 days followed by dual regimen of PPI+ amoxicillin fornext 7 days. Patients were asked to report at 7, 14 days and at6 weeks interval.Results: Out of 97 patients 93 patients became negative forH.pylori after 6 week of Reverse Hybrid eradication therapy.It was observed that majority of patients enrolled in the studywere in the age group of 41–60 years (50%) followed bybelow 40 yrs (27%), above 60 yrs (23%). Out of them, 74%were male and 26% were female.Conclusion: Out of 97 patients 93 patients became negativefor H.pylori after 6 week of Reverse Hybrid eradicationtherapy. Hence, Reverse Hybrid Therapy is equally potenttherapy to Bismuth based therapy though the latter has a lotof side effects.
