Efficacy of standard triple therapy versus Levofloxacin based alternate therapy against Helicobacter pylori infection.

OBJECTIVE: To assess the effectiveness of clarithromycin based standard triple therapy verses levofloxacin based first line therapy against Helicobacter pylori infection.

METHODS: This prospective observational study was performed at Akhter Saeed Trust Teaching Hospital, Lahore, from May 2016 to 31st May 2017 and comprised of all patients with positive H. pylori, confirmed by gastroscopic biopsy; fulfill the inclusion criteria of this study. Patients were divided into two groups (Group A and Group B). Group A received clarithromycin 500mg, amoxicillin 1g and omeprazole 20mg twice a day for two weeks. In group B levofloxacin 250mg was replaced by clarithromycin whereas rests of medicines remain the same. Patients were followed up at end of first week, second week and at end of treatment to record any adverse effects and cure rate. Data was analyzed by using SPSS version 24.0 and MINITAB V.16..

RESULTS: Out of 300 enrolled patients (150 patients in each group), 123 (87.85%) patients cured in group A whereas 134 (92.4%) patients cured in group B. Both treatment regimens were almost equally effective in our population with no statistically significant difference in outcome. Significantly less adverse effects were observed in patients having levofloxacin as compared to standard triple therapy.

CONCLUSIONS: Effectiveness of both standard triple therapy and alternate triple therapy were found satisfactory to be used for treatment in our region. Levofloxacin based alternate therapy is safer to the patients. It can be used in conditions where adverse effects caused by standard therapy are unbearable.
