Introduction: HCV infections are an important public health problem due to their high chronicity, cirrhosis and advanced complications like hepatocellular carcinoma. In HCV infections, it is important and necessary to determine genotypes before treatment because treatment times and protocols vary according to genotypes. The aim of this study was to determine the distribution of HCV genotypes in HCV-RNA positive individuals in Giresun province and to investigate whether there was a statistically significant difference between genotypes and patient ages. Materials and Methods: HCV-RNA level and HCV genotype of 147 patients were included in the study. HCV RNA levels of the samples were studied by QIAsymphony SP (Qiagen) automated device, genotype determination by Rotor Gene Q (Qiagen) automated device by “real-time polymerase chain reaction (PCR)” method. Each sample was tested for HCV genotypes 1a, 1b, 2, 3, 4, 5a and 6. Results: Of the 147 patients genotyped; 128 (87%) genotype 1b, 9 (6%) genotype 1a, 8 (6%) genotype 3, 2 (1%) genotype 2 were detected. Genotypes 4, 5a and 6 were not detected. According to the HCV genotype distribution, median age and range (min.-max.) of the patients weren50 (30-83) for 1a, 70 (22-87) for 1b, 48.5 (36-61) for 2 and 33 (25-52) for 3. HCV RNA levels were between 37 and 12.630.170 IU/mL. Conclusion: The predominant genotype in the world and Turkey is genotype 1b. In our study, the most common genotype was also genotype 1b (87%), consistent with other studies in our country. This study contributed to HCV genotype distribution data in our region and country.

The relationship between hepatitis C virus (HCV) infection and C-reactive protein (CRP), which is an inflammatory biomarker, is limited in studies with the general population. It was hypothesized that changes in CRP levels are genotype-dependent in the general population with HCV infection. Thus, this study aimed to assess the prevalence of HCV infection and compare CRP levels with an anti-HCV antibody, HCV-RNA status, and HCV genotypes. A total of 5611 adult participants from the National and Health Nutrition Examination (NHANES), 2009–2010 survey were analyzed. Proc survey frequency, means, and multivariate regression were used due to the complex survey design of NHANES. The prevalence of HCV infection among the study population was 1.6%. There were lower mean CRP levels among people with anti-HCV antibody positive status compared to those with antibody negative status (0.12 ± 0.08 vs. 0.24 ± 0.02, p = 0.08, 95% Confidence Intervals, CI: −1.12 to 0.07). Mean CRP levels were also lower in people with HCV-RNA positive status compared to those with HCV-RNA negative status (0.56 ± 0.03 vs. 0.48 ± 0.05, p = 0.62 and 95% CI: −1.37 to 0.86). However, these differences were non-significant. With respect to HCV genotypes, significantly higher CRP levels were noted among people infected with HCV genotype 2 vs. genotype 1 (0.53 ± 0.06 vs. 0.23 ± 0.05, p < 0.01, 95% CI: −0.58 to −0.02) and those with HCV genotype 2 vs. HCV genotype 3 (0.53 ± 0.06, 0.28 ± 0.04, p < 0.01, 95% CI: 0.02 to 0.48). Further studies are needed to confirm this finding.

Genotype distribution of hepatitis C virus (HCV) can vary over the years between different patient groups and regions. The prevalence of intravenous drug users (IVDU) is known to increase in our country, yet there are a limited number of studies investigating the distribution of HCV genotypes in this group. These data are essential for monitorization of the changes in HCV epidemiology. The present study aimed to evaluate the five-year results of HCV genotyping among patients infected with HCV related to IVDU and unrelated to drug use. Plasma samples of 720 patients (HCV antibody, HCV RNA positive), which were sent to our laboratory for HCV genotyping between January 2014-March 2019 were analyzed. HCV RNA extraction from plasma samples was performed in the automated-extraction system of EZ1 advanced (Qiagen, Germany) using the EZ1 virus mini kit v2.0 (Qiagen, Germany). Amplicons were obtained by amplifying the 5’NCR and core gene region in the Rotorgene 6000 real-time PCR (Qiagen, Germany) device with the HCV RNA real-time quantitative 2.0 (NLM, Italy) kit. For the genotyping, a commercial line probe assay (LIPA) based on in vitro reverse hybridization GEN-C2.0 kit (NLM, Italy) which can distinguish 1, 2, 3, 4, 6 genotypes and 1a, 1b, 2a/c, 2b, 3a, 3b, 3c, 3k, 4a, 4b, 4c/d, 4e, 4f, 4h, 5a, 6a/b, 6g, 6f/q, 6m, 7a subtypes of HCV, based on variations in the 5’-NCR and core regions was used. HCV genotype distribution of 266 IVDU (93.2%: male; median age: 25 ± 6.82) and 454 non-drug users (51.3%: male; median age: 56.5 ± 16.06) were examined. In order of frequency in the group with IVDU; genotype 1a, 3a, 1b, 4c/d, 2b, 4, 3 were observed and genotype 1, 2a/c and mixed genotype (1+3a) were detected in one patient. In the group without IVDU, in order of frequency; genotype 1b, 1a, 3a, 1, 2a/c, 4 were observed and genotype 2b, 4c/d, 5a, 6a/b, 6 and mixed genotype (3+4) were detected in one patient. Genotypes 1a and 3a were significantly higher in the IVDU group (p< 0.00001, p< 0.00001), while 1b was significantly higher in patients without IVDU (p< 0.00001). Genotypes 1a and 3a were more common in young men (p< 0.00001, p= 0.000163), while 1b was higher in middleaged women (p< 0.00001). The incidence of genotypes 1b (p= 0.021) and 3a (p= 0.012) was higher in foreign nationals than the Turkish patients. When the HCV genotype distribution was examined by years, it was observed that the percentages of genotype 1b and 1a were decreasing, while the percentage of genotype 3a was increasing. As a result, in this study, HCV genotype distribution among IVDU was observed to be different from the general population without IVDU. It was found that genotypes 1a and 3a were more common in the IVDU group. As in the other regions of our country, genotype 1b was found most frequently in the general population. Genotype 3a increases significantly compared to years. In our study, the determination of genotypes existing in different parts of the world may be due to the foreign nationals living in our city and our region is a tourism center. It is also necessary to investigate whether there is an increase in IVDU over the years.

Background: Hepatitis C virus (HCV) genotypes and subtypes exhibit significant geographic variations.Aim: To analyse the distribution of genotypes/subtypes of HCV in a group of patients with chronic hepatitis C from Canton Sarajevo during 2012-2018.Material and methods:The study enrolled 247 human plasma samples of HCV-RNA positive patients with available results of HCV genotyping test.Results: During 2012-2018, the domination of subtypes 1a (34.01%), 1b (28.34%) and genotype 3 (23.89%) was registered. In 2012 and 2013, HCV subtype 1a was the most common (27/63; 42.86% and 17/40; 42.50%, respectively). In 2014, the leading HCV genotype/subtype were 3 and 1b (17/57; 29.82%). In 2015, the dominance of HCV genotype 3 (14/39; 35.90%) continued, while in 2016, the same number of HCV subtypes 1a and 1b (11/30; 36.67%) was recorded. Although in a small number of tested, during 2017, HCV subtype 1b was the most prevalent (7/14; 50.00%), and in 2018, it was replaced by a HCV subtype 1a (3/4; 75.00%). Distribution of HCV genotypes/subtypes by age group of patients varied significantly (p=0.000). The largest number of patients (71/247; 28.74%) belonged to the age category 30-39 years and HCV genotypes/subtypes 1, 3, 4, 1a and 1b were identified. Except in 2017, male gender significantly dominated (p=0.000). In males, HCV subtype 1a (68/170; 40.00%) was the most common, while in women it was HCV subtype 1b (44/77; 57.14%).Conclusion: This six-year retrospective study showed the time variations of the circulating HCV genotypes/subtypes among patients with chronic hepatitis C in Canton Sarajevo. Genotyping of the HCV has an important implications for diagnosis and treatment of the patients.

Background: Determination of an individual's HCV genotypes prior to antiviral therapy has become increasingly important for the deciding clinical management and predicting prognosis of HCV infection. Relative genotype proportions are needed to inform to healthcare models, which should be geographically tailored. To our knowledge, there are no studies reporting genotype pattern in Rawalpindi/Islamabad region. We aimed to determine the frequency of different genotypes in HCV positive cases in the population of Rawalpindi/ Islamabad over the period of five years. Methods: Data of total of three thousand eight hundred and eighteen (n=3818) HCV positive adult of both genders were screened for genotype testing over the period of six years were analyzed. Results: Most frequent genotype identified in our study was genotype 3, accounting for 95.8% (n=3657) of HCV positive cases. The second most common genotype was Type 1 accounting for 2.9% (n=109) of HCV positive cases. Other genotypes were Type 2 (0.3%, n=12) and Type 4 (0.1%, n=5). Mixed genotype (Type 1 and 3) were detected in almost 1 % (n=35) of cases. We did not find genotype 5 and 6 in our study sample. No significant difference was observed among males and females in genotype distribution (P>0.05). Conclusion: The most common genotype among HCV patients were found to be genotype 3 followed by genotype 1 as the second most common in Rawalpindi/Islamabad region during the study period.
