Abstract
Background: The prevalence of carbapenem resistance in Acinetobacter baumannii has been increasing worldwide, and therapeutic options are extremely limited. We performed a systematic review to evaluate the phenotypic and genotypic carbapenem resistance in A.baumannii reported in Iran.
Methods: We systematically searched Pub Med, Web of Science Direct, and Google scholar databases to identify studies addressing the carbapenem resistance of A. baumannii. The selected papers were published between 2005 and 2016, but the sample collection period was between 2002 and 2016. To estimate the prevalence, the Der Simonian and Laird randomized models, a 95% confidence interval, was used. For the heterogeneity check, I2 test was used. The Egger test was used to check the propagation bias.
Results: Analysis of data indicates that there was an increase in resistance to carbapenems from 4.5% in 2005 to a 100% prevalence rate in 2016 (65.4 (95% CI: 58.8 – 71.6).
Conclusion: According to the results of this study, the rate of resistance to carbapenem in A.baumannii has been increasing in Iran. The presence of carbapenem-resistant isolates is a major concern, because carbapenem is the main drug used against Multi Drug Resistant (MDR) isolates.
Keywords: Carbapenem resistance, Acinetobacter baumannii, phenotypic, genotypic, multi drug resistant, nosocomial pathogens.
