چکیده
conclusions the genotype distribution of hcv takes diverse patterns in emro countries. genotypes 1 and 3 were predominant in iran and pakistan, while genotype 4 and 1 were the most common genotypes in the middle east arab countries and north african arab countries. understanding the genotypes of hcv can help policy makers in designing good strategies for treatment. results a total of 563 records were identified through the electronic search. of these records, 134 studies comprising 67681 hcv-infected individuals were included in the meta-analysis. in iran, subtype 1a was the predominant subtype with a rate of 42% (95% ci, 39 - 46), followed by subtype 3a, 35% (95% ci, 31 - 38). in pakistan, subtype 3a was the most common subtype with a rate of 56% (95% ci, 49 - 62), followed by subtype 3b, 10% (95% ci, 7 - 12). in saudi arabia and egypt, genotype 4 was the most prevalent genotype with a rate of 65% (95% ci, 59 - 72) and 69% (95% ci, 36 - 100) respectively. in tunisia and morocco, subtype 1b was the most common subtype with a rate of 69% (95% ci, 50 - 88) and 32% (95% ci, 7 - 56) respectively. context hepatitis c virus (hcv) infection is a major global public health issue. the eastern mediterranean regional office (emro) of the world health organization (who) seems to have one of the highest prevalence rates worldwide, with at least 21.3 million hcv-infected patients. objectives the aim of the present study was to review systematically all epidemiological data related to the prevalence of hcv genotypes in infected patients in emro countries. data sources a systematic search was conducted of peer-reviewed journals indexed in electronic databases (pubmed, scopus, isi, pakmedinet, and imemr, and persian-specific databases including sid, iran medex, and magiran). data extraction the prevalence rates of hcv genotypes were pooled by metan command in stata 14. statistical heterogeneity was explored using the i-square at the 5% significance level. publication bias was assessed, graphically and statistically, by funnel plot and begg and egger tests. study selection a systematic search was performed with temporal limits (papers published between january 2000 up to june 2015), regarding the prevalence and distribution of hcv genotypes in emro countries.
