Summary of the study:



         Helicobacter pylori (H. pylori) infection is described as the most common chronic bacterial infection in human, and is considered a primary cause of dyspepsia, gastritis and gastroduodenal ulcers.

Aim of the study:

          This study aimed to evaluate the H. pylori eradication rates associated with clarithromycin-based and levofloxacin-based regimens, and to investigate the factors potentially influencing treatment outcomes, as well as, the adverse effects caused by both regimens.

Materials and Methods:

         This is a comparative-prospective, randomised clinical trial study that has been conducted to compare the H. pylori eradication rates associated with a clarithromycin-based regimen and levofloxacin-based regimen. H. pylori infection was confirmed by a rapid urease test during endoscopy and its eradication by a urea breath test. The study has been conducted in the Gastroenterology and Hepatology Centre, Azadi Teaching Hospital, in Duhok. The data were collected through face-to-face interviews with the patients and according to the data collection form. The patients were followed up by the researcher via telephone calls and face-to-face interviews, during and at the end of the treatment protocol based on the study design. The data were analysed by using SPSS 21.0 statistical software.


          In this study, 192 patients were recruited; of these, 93 patients received a clarithromycin-based regimen and 99 a levofloxacin-based regimen. Sixty-four patients completed the clarithromycin-based regimen while 60 completed the levofloxacin-based regimen. The eradication success rate of the clarithromycin-based regimen was 52/64 (81.25%), while that of the levofloxacin-based regimen was 49/60 (81.66%) (p = 0.9524; odds ratio [OR] = 1.0280; confidence interval [CI] = 0.4153-2.5447). The rate of adverse effects was higher with the clarithromycin regimen than with levofloxacin regimen (p=0.001). Investigation of the risk factors associated with treatment failure showed that the overall efficacy of the regimens was influenced by body mass index (BMI), with a high failure rate observed in patients with a high BMI (p = 0.0174; OR = 1.1116; CI = 1.0187-1.2129). Age, sex, endoscopic diagnosis and smoking had non-significant influence on the treatment outcomes.


         The success rates of both regimens were high. The rate of adverse effects was higher with the clarithromycin-based regimen than with the levofloxacin-based regimen. High BMI was associated with high eradication failure rates. Further studies are needed to monitor the resistance of H. pylori to antibiotics.
