We've read with great interest the article entitled "Determination of hepatitis C virus genotypes among hepatitis C patients in Eastern Black Sea Region, Turkey" by Buruk et al. published in Mikrobiyol Bul 2013; 47(4): 650-7. In that study, the authors described the determination and distribution of hepatitis C virus (HCV) genotypes in Eastern Black Sea Region comprehensively. According to the current information, the determination of HCV genotypes is the most important factor for the management of therapy and virus-related complications, such as chirrhosis and hepatocellular carcinoma. The distribution of HCV genotypes varies geographically throughout the world. Therefore every country and even each region within the country should know the distribution of HCV genotypes to determine the appropriate treatment strategy. Herein we would like to contribute the data about distribution of HCV genotypes in whole Black Sea Region by presenting our current results obtained from Zonguldak province, where maximum number of chronic hepatit C patients have already been identified in Eastern Black Sea Region. A total of 53 chronic hepatitis C patients (26 female, 27 male; mean age: 57.1 ± 14.3, age range: 21-82 years) who were admitted to Zonguldak Ataturk State Hospital between January 2012-December 2013 were evaluated. Genotype analysis was performed by RealTime HCV Genotype II (Abbott Molecular, ABD) system. Genotype-1 was found to be the most frequently detected type with a rate of 96.2% (51/53). The prevalences of genotype-2 (1/53) and genotype-4 (1/53) were same, with a rate of 1.9%, in our study. Subtyping of genotype-1 strains yielded 52.9% (27/51) genotype-1b, 3.9% genotype-1a (2/51) and 47% untypeable genotype-1 (24/51). The present study was the second study from the Western Black Sea Region in our country, regarding HCV genotypes. In conclusion, considering entire Black Sea Region, genotype-1 is the most common genotype (96.2%), and 1b (52.9%) is the most common subtype, in parallel to the data reported from the other regions of Turkey.
