The aim of the current study was to surveyantibiotic resistance and also to determine influence of PPARγ polymorphism in patients with H. pylori infection.During an 11-month-period, 98 H. pylori isolates were collected from 104 biopsy specimens. In vitro susceptibilityof H. pylori isolates to 4 antimicrobial agents metronidazole, clarithromycin, amoxicillin and tetracycline wereassessed by quantitative method according to European Committee on Antimicrobial Susceptibility Testing(EUCAST) guideline. PPARγ polymorphism was determined using polymerase chain reaction-restrictionfragment length polymorphism assay. The frequency of H. pylori infection in our study was 94.2%. In vitrosusceptibility data showed that highest level of resistance was related to metronidazole (66.3%), and the majorityof H. pylori isolates were highly susceptible to amoxicillin and tetracycline (94.9% and 96.9%, respectively).Genotypic frequencies were 25.5% for CC (Pro12Pro), 40.8% for GC (Pro12Ala) and 33.7% for GG (Ala12Ala).In our study, CG genotype had highest distributions among infected patients with H. pylori. The study suggeststhat the PPAR-γ Pro12Ala polymorphism could be evaluated as a potential genetic marker for susceptibility togastric cancer in the presence of H. pylori infection.
