The increasing antimicrobial resistance of <i>Shigella</i> species among Iranian pediatrics: a systematic review and meta-analysis

Abstract

BackgroundShigellosis remains one of the global causes of morbidity and mortality. However, the global emergence of antibiotic resistance has become the leading cause of treatment failure in shigellosis. This review aimed to provide an updated picture of the antimicrobial resistance rates in Shigella species in Iranian pediatrics.MethodsA comprehensive systematic search was performed on PubMed, Scopus, Embase, and Web of Science until 28 July 2021. The meta-analysis was performed by computing the pooled using a random-effects model with Stata/SE software, v.17.1. The discrepancy within articles was surveyed by the forest plot in addition to the I-2 statistic. All statistical interpretations were reported on a 95 confidence interval (CI) basis.ResultsTotally, of 28 eligible studies published between 2008 and 2021. The pooled prevalence rate of multidrug-resistant (MDR) was 63 (95 CI 50-76). Regarding suggested antimicrobial agents for Shigella species, the prevalence of resistance for ciprofloxacin, azithromycin, and ceftriaxone as first- and second-line treatments for shigellosis were 3, 30, and 28, respectively. In contrast, resistance to cefotaxime, cefixime, and ceftazidime was 39, 35, and 20. Importantly, subgroup analyses indicated that an increase in resistance rates during the periods (2008-2014, 2015-2021) was recognized for ciprofloxacin (0 to 6) and ceftriaxone (6 to 42).ConclusionOur findings revealed that ciprofloxacin is an effective drug for shigellosis in Iranian children. The substantially high prevalence estimation proposes that the first- and second-line treatments for shigellosis are the major threat to public health and active antibiotic treatment policies are essential.
