Abstract
Context: Group B Streptococcus has the capacity of being colonized in the rectovaginal organ of women and causes infections in a mother and her fetus, thereby leading to neonatal diseases. Evidence Acquisition: The aim of this review was to summarize all of the relevant articles published to highlight the prevalence of group B Streptococcus colonization or infection in different regions of Iran. A systematic literature review was conducted by searching PubMed, Scopus, Web of Science (ISI), ScienceDirect, Google Scholar, and domestic databases for papers published in English or Persian from 1992 up to July 2019, concerning the prevalence of group B Streptococcus among Iranian women. All information regarding year, location of cases, frequency, author’s name, date of publication, participants, pregnancy period, sampling, and quality assessment were recorded. Summary effects were derived using the random effects model. Results: Among 61 suitable papers, data revealed that 36,807 cases of pregnant and non-pregnant women had been tested for group B Streptococcus during 1992-2018. Overall, 11.9% of pregnant and 5.3% of non-pregnant women were positive. Further results were as follows: vaginal, recto-vaginal, rectal, and endocervical colonization rates were 12.9%, 9.7%, 18.5%, and 3.7%, respectively. Group B Streptococcus incidence was the highest in Sanandaj (61.5%), and the lowest in Tabriz (1.8%). Conclusions: Although the prevalence distribution in Iran seems to be acceptable, more investigations are needed to represent the real incidence of group B Streptococcus around the country. In addition, a program with a standard lab technique is needed to screen pregnant women for further treatment before birth.
