An Updated Systematic Review and Meta-Analysis on the Helicobacter pylori Antibiotic Resistance in Iran (2010–2020)

خلاصه انگلیسی

This updated systematic review and meta-analysis followed two objectives: (1) to determine Helicobacter pylori antibiotic resistance in Iran during 2010–2020 and (2) to assess the trend of resistance from 1997 to 2020. A systematic search in multiple databases, including ISI Web of Knowledge, PubMed, Scopus, Google Scholar, and the Scientific Information Database (SID), was performed using MeSH-extracted keywords. Meta-analysis was done on extracted data from a total of 27 included citations published between 2010 and January 20, 2020. The overall mean prevalence of H. pylori resistance was 64.9% for metronidazole, 25.3% for clarithromycin, 20.7% for amoxicillin, 16.1% for tetracycline, 21.9% for levofloxacin, 22.8% for rifampicin, 27.2% for furazolidone, 32.3% for ciprofloxacin, and 38.7% for erythromycin. In addition, the prevalence of multidrugresistant strains of H. pylori was 26.5% in Iran. The pooled prevalence of point mutations A2143G, A2142G, and A2142C associated with clarithromycin resistance were 46.6%, 37.2%, and 5.5%, respectively; mutations in frxA and rdxA genes associated with metronidazole resistance were 46.4% and 19.7%, respectively; gyrA and gyrB genes mutations among fluoroquinolone-resistant strains were 55.3% and 48.2%, respectively; and resistance associated with integrons was 47%. According to the present findings, resistance of H. pylori to antibiotics used for eradication therapy has reached an alarming level in Iran. Furthermore, the trend of H. pylori resistance has increased between 1997 and 2020. Hence, continuous surveillance on resistance patterns, logical prescription and appropriate consumption of antibiotics, and selecting effective therapeutic regimens in accordance with local resistance patterns are required to prevent further spread of resistance and ensuing treatment failures.
