Abstract
BACKGROUND Generally, hepatitis C has been identified as one of the major health issues that about 3% of the world's population have been threatened and affected by it (about 170 million people), and also, it can be considered a factor in acute and chronic hepatitis. METHODS The aim of this study is to determine the prevalence of HCV genotypes in Azerbaijan patients. In this study, sampling was done on the referred patients to the hospitals (Mahallati and Behbud Hospital). RNA was extracted after isolation of plasma, and then, after the synthesizing of cDNA, the sample was carried out to the laboratory for performing the real-time PCR in order to determine the genotypes. RESULTS The evaluation of HCV genotypes in positive plasma samples showed that dominant subsets were remarkable and the mean age of the patients was 37/3 ± 11/8 (in the age range of 2-63). Among the 235 patients,139 of them (59%) were male. Statistically, the average number of women was more than men (T test, P < 0/05). 1b genotype was reported 70% in the patients above 40 years old, and also, it was reported as 71/6% in the patients under 40 years old that was not statistically significant. The incidence of serotype 3a was higher among the patients younger than 40 years old (3a was 18.1% vs. 15%), and this serotype was prevalent among men (3a was 18.7% vs. 14.6%), which was statistically significant. CONCLUSION The findings indicate that among Azerbaijan's patients with chronic hepatitis C, genotypes 1b (71.1%) and 3a (17%) were dominant.

Abstract
OBJECTIVE Hepatitis C virus (HCV) genotyping is an important part of pre-treatment diagnostic algorithms as it guides the choice of therapeutic regimens. The aim of this study was to analyse the distribution of HCV genotypes in patients with chronic hepatitis C from Croatia in the period 2008-2015. METHODS The study enrolled 3,655 anti-HCV positive patients with available results of HCV genotyping from the three largest national HCV genotyping laboratories. RESULTS The majority of HCV-infected individuals enrolled in the study were male (70.7%). Analysis of age distribution in a subset of 2,164 individuals showed a mean age of 40.9 years (SD 11.77 years). Croatian patients were mostly infected with HCV genotype 1 (56.6%), followed by genotype 3 (37.3%), genotype 4 (4.2%) and genotype 2 (1.8%). Genotype 1 subtyping in a subset of 1,488 patients showed 54% (803/1,488) of 1b infections and 46% (685/1,488) of 1a infections. Percentages of genotype 1 were the highest in Central/Northwestern and Eastern Croatia and the lowest in the Central/Southern Adriatic Region. Genotype 3 was most frequently found in the Central/Southern Adriatic Region (49.1%) but represented only 17.5% of infections in Eastern Croatia (p < 0.001). CONCLUSIONS The results of this nine-year retrospective analysis on the distribution of HCV genotypes and subtypes in 3,655 HCV-infected individuals from Croatia showed that the majority of infections can be attributed to genotypes 1 and 3 with absence of major changes in the molecular epidemiology of the two most frequent HCV genotypes infection in Croatia in the past 20 years.

Abstract
BACKGROUND & AIMS Hepatitis C viral infection (HCV) after injection drug use is very prevalent. The kind of genotype determines the response to treatment. However, no systematic review update on the global genotype distribution of HCV in people who inject drugs (PWID) is currently available. METHODS A systematic review was performed by using the keywords: Genotype, Hepatitis C, Injection drug user/Intravenous drug user/Substance user/ PWID, Name of countries in Pubmed, Embase and PsycINFO. The results were compared with the review of Gower et al. in 2014, concerning the distribution of HCV genotypes in the general HCV population. RESULTS Using these keywords, 132 studies in 48 countries (from 1995 to 2015) were collected. After grading these results, the data of 48 studies were used to determine the distribution of genotypes in PWID. Genotype 1 is the most prevalent genotype all over the world in PWID. In Europe, genotypes 1, 3 and 4 are highly prevalent. In North and South America and in Australia genotype 1 and 3 are most prevalent. In Asia genotype 2 and 6, and Africa genotype 1a and 4 are mostly observed. Overall, the most important differences comparing with the general population are a lower prevalence of genotype 1b in the PWID population and higher prevalence of genotype 1a and 3. CONCLUSIONS There is a different prevalence of genotype distribution in PWID than in the general population. Genotype 3 is especially highly prevalent in the Western countries. LAY SUMMARY Hepatitis C viral infection after injection drug use is very prevalent. The most important genotype causing HCV infection in PWID globally is genotype 1, as is the case in the general population, but also genotype 3 is highly prevalent in PWID. Genotype 4 is most prevalent in Africa, spreading into Europe, whereas genotype 2 and 6 are more located in Asia. The most important difference comparing to the general population are generally lower prevalence of genotype 1b, and higher prevalence of genotype 1a and 3 in PWID. As the genotype nowadays still determines the treatment, and as there is a different genotype distribution than in the general population, it is important to identify the genotype also in PWID.

Abstract
Approximately 170 million people in the world are infected with Hepatitis C virus (HCV). There are no published population based studies about the prevalence of HCV genotypes and the associations of genotype and Infection frequency with gender and age in WuHan. We aimed to investigate the distribution of HCV prevalence and genotypes among different gender and age patients with chronic HCV infection in WuHan from 2011 to 2015. A total of 2685 anti-HCV positive serum samples from individuals of physical examinationwere recruited from the Renmin Hospital of WuHan University, Hubei Province in China from January 2011 to December 2015. From these 2685 anti-HCV positive serum samples, 496 samples were with a positive PCR for HCV RNA. The number of HCV infection showed an increase with year, but the annual infection rate has remained similar (χ2 = 2.94, P = 0.568). 2685 cases were infected with HCV from 2011 to 2015 in WuHan city of China. Blood transfusion (18.14 %) was the main routs of transmission, followed by Surgery (8.94 %). The highest prevalence of HCV infection was at the age group 50–59 (25.85 % of 2685) and the lowest prevalence was 0–9 (0.93 % of 2685). HCV genotype 1 was the most prevalent (73.39 %), followed by genotypes 2 (17.14 %), 3 (5.25 %) and 6 (3.22 %). Genotype 4 and 5 was not detected in these patients. The most prevalent subtype was subtype 1b (71.98 %), followed by genotypes 2a (17.14 %). Five patients had mixed infection across the HCV subtypes. Among all genotypes, genotype 1 was highest in both male (73.27 %) and female (73.47 %) patients, followed by genotype 2. Genotype 1 (male: 29.84 % of 496, vs female: 43.55 % of 496, χ2 = 20.07, P < 0.0001), genotype 2 (male: 6.25 % of 496, vs female: 10.89 % of 496, χ2 = 6.81, P = 0.009), and 6 (male: 1.41 % of 496, vs female: 1.81 % of 496, χ2 = 0.626, P = 0.401) were more common in female patients than males, while no significant gender differences were observed for genotype 6. Among age group 50–59 years Genotype 1 was most common in male patients (29.05 % of 148) followed in 20–29 years (23.65 % of 148), genotype 2 in the age group 60–69 (12 cases of 31) and genotype 3 in the age group 50–59 (4 cases of 13) and genotype 6 was most frequent in the age group 30–39 (4 cases of 7). The frequency of HCV prevalence was significantly higher in female patients compared to males before ages 60, while the opposite result was observed after 60 years. The most common HCV genotype in WuHan was subtype 1b followed by 2a and more common among women than males patients. Further studies are needed to collect a large number of samples to estimate the different epidemiology of the HCV genotypes, because the sample size of non-genotype 1b and 2a is not large enough and other factors like disease history/monthly income/etc. are not included in our study.

The Prevalence of Hepatitis C Virus Core Amino Acid 70 Substitution and Genotypes of Polymorphisms Near the IFNL3 Gene in Iranian Patients With Chronic Hepatitis C. HEPATITIS MONTHLY 2016; 16:e37011. [PMID: 27630727 PMCID: PMC5010881 DOI: 10.5812/hepatmon.37011] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/09/2016] [Revised: 03/06/2016] [Accepted: 03/18/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND Molecular studies have demonstrated that the hepatitis C virus (HCV) genotype and host genetics play predictive roles in the management of patients infected with HCV. OBJECTIVES This study aimed to investigate the HCV genotype, core amino acid (aa) 70 substitution, and polymorphisms near the IFNL3 gene (including rs12979860 and rs8099917) among Iranian patients with chronic hepatitis C (CHC). PATIENTS AND METHODS In this cross-sectional study, the molecular profiles of the HCV genotype, core aa 70 substitution, and rs12979860 and rs8099917 polymorphisms and plasma HCV RNA levels were determined in 429 CHC patients including 141 hemophilic, 84 thalassemic, and 204 non-hemophilic, non-thalassemic patients. RESULTS The hepatitis C virus subtype 1a was the most common subtype in the study population. Core aa substitution Arg70Gln was strongly associated with cirrhosis (OR = 2.49; 95% CI = 1.13 - 5.50; P = 0.020). Core aa 70 substitutions were more frequently observed in patients with the HCV subtype 1b than in patients with any other HCV subtypes (P < 0.001). Core aa 70 substitutions were also more common in patients with the rs12979860 TT genotype than in patients with non-TT genotypes (17.3% vs. 8.5%, P = 0.022) and also in rs8099917 non-TT genotypes than in the TT genotype (14.0% vs. 7.0%, P = 0.026). The HCV genotypes and rs8099917 polymorphisms were correlated in which HCV subtype 1b was in favor of rs8099917 GG and HCV subtype 3a favored rs8099917 TT (P = 0.021). Furthermore, the rs12979860 TT and rs8099917 GG genotypes showed significantly lower HCV RNA levels than the other genotypes (P < 0.001). CONCLUSIONS There is an as yet unexplained association between HCV and host parameters with unknown mechanisms in patients with chronic HCV infection. The assessments of core aa 70 substitution and polymorphisms near the IFNL3 gene could offer promising steps to improve the management of patients with HCV.

Abstract
BACKGROUND Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide, making it one of the world's major infectious diseases. There are no published population based studies about the prevalence of HCV genotypes in Bahrain. OBJECTIVES Therefore, the aim of the present study was to investigate the prevalence and distribution of HCV genotypes and subtypes among a large sample of patients with chronic HCV infection in Bahrain. PATIENTS AND METHODS Serum samples were collected from 202 HCV positive patients; of them 128 had a viral load (> 500 IU/mL) suitable for the type-specific genotyping assay. Gender-wise and age-wise differences in the distribution of HCV genotypes were determined by Chi Square and Fisher's Exact tests. RESULTS The predominant genotype among Bahraini patients was type 1 (36.71%), followed by genotypes 3 and 4 (15.6% each) and the lowest frequency was found for genotype 2 (3.9%). Among genotype 1, subtype 1b had the highest frequency (21.09%), followed by subtype 1a (14.06%). Among genotype 3, subtype 3a had the highest frequency (11.72%), while among genotype 4, most of subtypes were undetermined. The frequency of all different HCV genotypes was higher in male patients compared to female patients. Genotype 1 was most common in the age group of 51 - 60 years (38.3%), genotype 2 in 21 - 30 years (60%) and genotype 3 in 51 - 60 years (30%), while genotype 4 was most frequent among the age group > 61 (40%). CONCLUSIONS The most common HCV genotype in Bahrain was subtype 1b followed by 1a and 3a. Further studies involving sources of transmission in Bahrain are required to enhance control measures for HCV infection.

Abstract
The total number, morbidity and mortality attributed to viraemic hepatitis C virus (HCV) infections change over time making it difficult to compare reported estimates from different years. Models were developed for 15 countries to quantify and characterize the viraemic population and forecast the changes in the infected population and the corresponding disease burden from 2014 to 2030. With the exception of Iceland, Iran, Latvia and Pakistan, the total number of viraemic HCV infections is expected to decline from 2014 to 2030, but the associated morbidity and mortality are expected to increase in all countries except for Japan and South Korea. In the latter two countries, mortality due to an ageing population will drive down prevalence, morbidity and mortality. On the other hand, both countries have already experienced a rapid increase in HCV-related mortality and morbidity. HCV-related morbidity and mortality are projected to increase between 2014 and 2030 in all other countries as result of an ageing HCV-infected population. Thus, although the total number of HCV countries is expected to decline in most countries studied, the associated disease burden is expected to increase. The current treatment paradigm is inadequate if large reductions in HCV-related morbidity and mortality are to be achieved.

Abstract
Detailed, country-specific epidemiological data are needed to characterize the burden of chronic hepatitis C virus (HCV) infection around the world. With new treatment options available, policy makers and public health officials must reconsider national strategies for infection control. In this study of 15 countries, published and unpublished data on HCV prevalence, viraemia, genotype, age and gender distribution, liver transplants and diagnosis and treatment rates were gathered from the literature and validated by expert consensus in each country. Viraemic prevalence in this study ranged from 0.2% in Iran and Lebanon to 4.2% in Pakistan. The largest viraemic populations were in Pakistan (7 001 000 cases) and Indonesia (3 187 000 cases). Injection drug use (IDU) and a historically unsafe blood supply were major risk factors in most countries. Diagnosis, treatment and liver transplant rates varied widely between countries. However, comparison across countries was difficult as the number of cases changes over time. Access to reliable data on measures such as these is critical for the development of future strategies to manage the disease burden.

Abstract
The majority of people infected with hepatitis C virus (HCV) are unaware of their infection. Assessment of the prevalence of HCV infection in the general population and in key populations at increased risk is needed for evidence-based testing policies. Our objectives were to estimate the prevalence of antibodies to HCV (anti-HCV), the prevalence of HCV viraemia (HCV RNA), and to describe HCV genotype distribution among pregnant women in Slovenia. Unlinked anonymous testing was performed on residual sera obtained from 31,849 pregnant women for routine syphilis screening during 1999, 2003, 2009, and 2013. Anti-HCV reactive specimens were tested for HCV RNA and HCV genotypes were determined. Annual prevalence of anti-HCV ranged between 0.09% (95% confidence interval (CI): 0.03–0.18) in 2009 and 0.21% (95% CI: 0.12–0.34) in 2003 and HCV RNA positivity between 0.06% (95% CI: 0.02–0.14) in 2009 and 0.14% (95% CI: 0.07–0.25) in 2003. We observed no statistically significant differences in anti-HCV or HCV RNA prevalence between age groups (<20, 20–29 and ≥30 years) in any year and no trend in time. Of 29 HCV active infections, 19 were with genotype 1 and 10 with genotype 3. HCV infection among pregnant women was rare suggesting a low burden in the Slovenian general population. Antenatal screening for HCV in Slovenia could not be recommended.

Abstract
Background: Hepatitis C virus (HCV) infection still exists as a health concern among the transplant patients. Because of the severity of the disease, different responses to treatment, and side effects resulting from long therapeutic period, determination of genotypes and viral loads can help choose the best treatment protocols. Objectives: This study aimed to determine the HCV genotypes and its distribution patterns among liver, kidney, and bone marrow recipient candidates across Iran, referred to Namazi Hospital, southern Iran. Patients and Methods: A total of 101 individuals, including 44 (43.6%) liver, 55 (54.5%) kidney, and 2 (2%) bone marrow recipient candidates, with ages ranging between 5 and 74 years (Mean ±SD: 46.53 ± 13.73 y) participated in this study. From those, whole blood sample were collected and anti-HCV antibodies, RNA detection, and genotyping were performed on plasma using commercial chromatographic immunoassay, TaqMan one-step real-time polymerase chain reaction (RT-PCR), and genotyping RT-PCR kits, respectively. The frequencies of anti-HCV antibodies, RNA, various genotypes, and the viral load were compared with respect to gender, age, and transplant recipient groups. Results: Of 101 individuals, 47 (46.5%) were positive for anti-HCV antibodies and 34 (33.7%) for RNA with a significant difference (P < 0.05). RNA copy number ranged from 4.6 × 103 to 3.11 × 107 copies/mL, median: 2.92 × 106 copies/mL, with no statistical differences in all groups. Analyses revealed no significant differences between the frequencies of anti-HCV antibodies or RNA in different groups. The frequencies of the genotypes 1 (50%) and 3 (35.3%) were higher than those of the genotypes 2 (2.9%), 4 (2.9%), and undetermined one (8.8%). Genotype 1 was significantly more prevalent in liver transplant recipients, those older than 40 years, and male cases (P < 0.05). Conclusions: Considering the high frequency of genotypes 1 and 3 among the studied groups, it is suggested that before and after transplantation programs be improved to manage and treat the disease efficiently, based on the standard protocols for such genotypes in the region. Accordingly, the occurrence of post-transplant complications due to immunosuppression among all the recipients as well as reinfection in HCV infected liver transplant patients can be diminished.

Hepatitis C virus infection epidemiology among people who inject drugs in Europe: a systematic review of data for scaling up treatment and prevention. PLoS One 2014; 9:e103345. [PMID: 25068274 PMCID: PMC4113410 DOI: 10.1371/journal.pone.0103345] [Citation(s) in RCA: 178] [Impact Index Per Article: 17.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2014] [Accepted: 06/29/2014] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND People who inject drugs (PWID) are a key population affected by hepatitis C virus (HCV). Treatment options are improving and may enhance prevention; however access for PWID may be poor. The availability in the literature of information on seven main topic areas (incidence, chronicity, genotypes, HIV co-infection, diagnosis and treatment uptake, and burden of disease) to guide HCV treatment and prevention scale-up for PWID in the 27 countries of the European Union is systematically reviewed. METHODS AND FINDINGS We searched MEDLINE, EMBASE and Cochrane Library for publications between 1 January 2000 and 31 December 2012, with a search strategy of general keywords regarding viral hepatitis, substance abuse and geographic scope, as well as topic-specific keywords. Additional articles were found through structured email consultations with a large European expert network. Data availability was highly variable and important limitations existed in comparability and representativeness. Nine of 27 countries had data on HCV incidence among PWID, which was often high (2.7-66/100 person-years, median 13, Interquartile range (IQR) 8.7-28). Most common HCV genotypes were G1 and G3; however, G4 may be increasing, while the proportion of traditionally 'difficult to treat' genotypes (G1+G4) showed large variation (median 53, IQR 43-62). Twelve countries reported on HCV chronicity (median 72, IQR 64-81) and 22 on HIV prevalence in HCV-infected PWID (median 3.9%, IQR 0.2-28). Undiagnosed infection, assessed in five countries, was high (median 49%, IQR 38-64), while of those diagnosed, the proportion entering treatment was low (median 9.5%, IQR 3.5-15). Burden of disease, where assessed, was high and will rise in the next decade. CONCLUSION Key data on HCV epidemiology, care and disease burden among PWID in Europe are sparse but suggest many undiagnosed infections and poor treatment uptake. Stronger efforts are needed to improve data availability to guide an increase in HCV treatment among PWID.

Abstract
Hepatitis C virus (HCV) has infected approximately 170 million people worldwide. While the seroprevalence of anti-HCV antibody among Iranian blood donors is 0.13%, HCV infection is prevalent in 59-80% of Iranian injecting drug users. One hundred seventy-eight anti-HCV positive patients were referred to the Gastroenterology Department at the Taleghani Hospital (Tehran, Iran) between June 2007 and June 2012. Out of 178 samples, 142 were positive for HCV-RNA. HCV subtypes were determined using phylogenetic analysis of the NS5B or 5'UTR/core regions. Of 142 viremic patients, 71 (50%) were infected with HCV subtype 1a, 43 (30.3%) with subtype 3a, 20 (14.1%) with subtype 1b, 3 (2.1%) with subtype 4d, 2 (1.4%) with subtype 4a, 1 (0.7%) with subtype 2b, and 1 (0.7%) with subtype 6a. Interestingly, genetic analysis of a sub-genomic fragment from one patient identified a non-subtypeable HCV genotype-3 strain. There was a significant association between HCV subtype and a history of injecting drug use (P = 0.003). Subtype 3a was predominant among patients with such a history. Injecting drug use was associated with younger age (P < 0.001). HCV subtype was also significantly associated with a history of upper gastrointestinal endoscopy (P = 0.02). Subtype 1a was more frequent among patients with such a history. In addition, history of upper gastrointestinal endoscopy was significantly associated with older age (P = 0.002). In conclusion, while HCV subtype 1a is predominant among infected Iranian individuals, subtype 3a is predominant among Iranian injecting drug users.

Abstract
Early detection and genotyping of HCV infection is important for disease management. It is important to develop fast and cost-effective semi-automated techniques allowing an accurate and reproducible detection, quantification and genotyping of HCV. The proposed protocol includes a real-time RT-PCR assay for HCV detection/quantification and a type-specific one-tube RT-PCR assay for genotyping. Both assays detect genotypes 1-4 as intended. The limit of detection was 112IU/ml for the real-time assay and 600±278IU/ml (mean±SD) for the genotyping assay. Concordance between the real-time assay and AMPLICOR HCV v2.0 test was 100%. The real-time assay has wide linear dynamic range of detection and quantification and excellent reproducibility with 2% and 0.75% coefficients of variations, for inter- and intra-assays, respectively. The observed correlation with AMPLICOR HCV Monitor v2.0 kit was linear with the correlation coefficient of 0.988. The diagnostic specificity and sensitivity of the genotyping assay, tested on 102 samples, was 100% and 95%, respectively. The overall procedure of HCV diagnosis is completed within 6h in a closed system with minor contamination risk. In addition to being fast and cost-effective, this approach is reproducible and avoids post-PCR enzymatic and hybridization steps while detecting and genotyping HCV with high clinical sensitivity.

Abstract
Hepatitis C virus (HCV) infection is a worldwide concern. Knowledge of the HCV genotype is clinically important because it predicts the rate of response to therapy and guides the treatment duration. Moreover, it allows molecular epidemiology to be performed. To our knowledge, the prevalence of HCV genotypes has been assessed only once in Albania, using a line probe genotyping assay. We determined HCV genotypes by population sequencing of HCV-infected patients in Tirana, Albania. HCV genotype and sequence analyses were performed for serum samples collected from January 2011 through May 2012 from 61 HCV-seropositive patients using population sequencing of the NS3 protease gene and alternatively the NS5b gene and the 5' untranslated region (UTR). HCV RNA was retrieved from the blood samples of 50 patients. The HCV NS3 protease gene was sequenced for 28 patients and NS5b and/or 5'UTR fragments were sequenced for an additional 22 patients. The predominant genotype was 1b in 25 patients (50%), followed by genotypes 2c, 4a, 3a, and 1a in 18%, 14%, 8%, and 6% of cases, respectively. Best matches for these HCV RNAs in GenBank were obtained in different countries worldwide. One NS3 protease naturally harbored an amino acid conferring minor drug resistance to newly available HCV protease inhibitors. In conclusion, HCV-1b was predominant in the present Albanian population, as in southeastern Europe.

Abstract
OBJECTIVES The combination of pegylated interferon-α and ribavirin is a standard-of-care (SOC) treatment for chronic hepatitis C (CHC), and it achieves a sustained virological response (SVR) in 41-52% of genotype 1 and in 73-79% of genotype 3 patients. In a few clinical trials, the combination of fluvastatin and SOC increased the SVR in genotype 1 patients. METHODS This prospective study enrolled 179 naïve CHC patients. In the fluvastatin group patients received the combination of SOC and fluvastatin 80 mg daily; historical controls matching the study group in genotype, age and gender were treated with the SOC treatment only. RESULTS On-treatment viral responses as well as the SVR did not differ significantly between the two groups, except for the genotype 1 patients with a high viral load presenting a significantly higher SVR rate in the fluvastatin group (75%) compared to the control group (41%; p = 0.024). Multivariate logistic regression identified hepatitis C virus (HCV) genotype 3 infection (p < 0.001), age ≤40 years (p < 0.001), liver steatosis <5% (p < 0.01) and low viral load (p < 0.001) as independent predictors of an SVR. CONCLUSION A combination of fluvastatin and SOC significantly improved the SVR in naïve CHC patients infected with HCV genotype 1 and high viral load, but it did not improve the SVR in patients infected with HCV genotype 3.

Abstract
BACKGROUND Determination of the Hepatitis C virus (HCV) genotype distributed in a particular area has an important role on public health throughout the world. OBJECTIVES The aim of this study was to determine the frequency of HCV genotypes in Azerbaijani patients. PATIENTS AND METHODS From March 2010 until March 2012, 235 Azerbaijani patients with established chronic hepatitis C, referred to Hospitals related to Iran University of Medical Sciences and Tehran Hepatitis Center, Clinical department of Baqiyatallah Research Center for Gastroeneterology and Liver Disease, were enrolled in this cross sectional study. About 5 mL of peripheral blood was collected from patients and after separation of plasma, viral RNA extracted. HCV-RNA were amplified by RT-nested PCR using primers from the 5´-UTR and genotyped by RFLP assay, and then HCV genotypes were confirmed using sequencing of cloned PCR products into pJET1.2/blunt cloning vector. RESULTS HCV genotyping of positive plasma samples demonstrated that predominant HCV subtype was noted for 1b (71.1%) followed by subtype 3a (17.0%), genotype 2 (6.8%), 1a (1.7%), and mixed infection (3.4%). The mean ± SD age of patients was 37.3 ± 11.8 (range: 2-63) years. Out of 235 patients, 139 (59.1%) were male. The frequency of HCV subtype 3a was higher in patients under 40 years old (3a: 18.1% vs. 15.0%), and subtype 3a was higher in male patients (3a: 18.7% vs. 14.6%). CONCLUSIONS The current study shows that the predominant HCV genotype among Azerbaijani patients with established chronic hepatitis C is subtype 1b (71.1%) followed by subtype 3a (17.0%).

Abstract
The prevalence of hepatitis C virus (HCV) genotypes depends on geographical location. HCV genotyping is important for epidemiological investigations and treatment management. The aim of this study was to determine the HCV genotype prevalence in the most prominent risk groups in the Republic of Macedonia in the last 5 years and to evaluate its association with patient's age, gender, and mode of transmission. A total of 1,167 HCV positive patients, divided into three risk groups (intravenous drug use, chronic hemodialysis, and other risk factor), were genotyped using an in-house ASO hybridization method with genotype-specific oligonucleotide probes. The genotypes 1, 2, and 3 were present with 52.2%, 0.6%, and 47.0%, respectively. Genotype 1 was most prevalent in hemodialysis (89.0%) and other risk factor group (53.8%). It was found associated independently with hemodialysis, age >40 and female gender. Genotype 3 predominated in intravenous drug users (64.0%) and was associated significantly also with age ≤40 and male gender. Multivariable logistic regression analysis pointed out hemodialysis (P < 0.0001, Exp (B) = 12.0) as a positive predictor factor for genotype 1 and age ≤40 (P = 0.021, Exp (B) = 1.8) and intravenous drug use (P < 0.0001, Exp (B) = 8.4) as a positive predictor factors for genotype 3. In conclusion, the main transmission route of HCV infection in the Republic of Macedonia is intravenous drug use, followed by hemodialysis. HCV genotypes 1 and 3 dominate in these two most prominent risk groups in the Republic of Macedonia.

Abstract
Little is known about the epidemiological characteristics of HIV/hepatitis C virus (HCV) co-infection in cities in China with low HIV prevalence. This study evaluated the level of exposure to different risk factors associated with HCV transmission and characterized the distribution of HCV genotypes in 356 HIV-1-positive patients in Wuhan, central China. HIV transmission routes were distributed as follows: heterosexual contact, male-to-male sexual contact, intravenous drug use, blood transfusion, and unknown route. HCV antibodies were detected by a third-generation enzyme-linked immunosorbent assay. HCV-positive plasmas were subjected to RNA extraction, RT-PCR amplification, and sequencing. Phylogenetic analysis characterized HCV subtypes and the evolutionary origin of circulating HCV strains. Ninety-two of 356 (25.8%) patients infected with HIV were anti-HCV-positive. Among co-infected patients, the predominant risk for HCV transmission was intravenous drug use (87.3%). Six HCV subtypes (1a, 1b, 2a, 3a, 3b, and 6a) were detected. HCV genotype 6a was most prevalent, occurring in 39.3% of all patients, followed by genotypes 1b (24.7%), 3b (18.0%), and 3a (9.8%). The least frequent genotypes were 1a (4.9%) and 2a (3.3%). Intravenous drug use was strongly associated with genotype 6a, and infection by blood or blood product transfusion was strongly associated with genotype 1b. Genotype 2a was detected only among those infected by male-to-male sexual contact. The distribution of HCV subtypes suggests that the city plays a crucial role as a hub of HCV transmission in China. Exposure to multiple risk factors associated with HCV transmission was common among patients co-infected with HIV and HCV.

Abstract
BACKGROUND Hepatitis C virus (HCV) has different genotypes throughout the world. Since the determination of which antiviral treatment to be applied is related to HCV genotypes, identification of an individual's HCV genotypes prior to antiviral therapy is critical. OBJECTIVES The purpose of this study was to investigate the distribution of HCV genotypes in a large population of Iranian HCV infected patients. PATIENTS AND METHODS Eleven thousand, five hundred and sixty one patients with chronic HCV infection which referred to hospitals related to the Tehran University of Medical Sciences and Tehran Hepatitis Center-Clinical Department of Baqiyatallah Research Center for Gastroeneterology and Liver Disease from March 2003 to December 2011 were enrolled. Following extraction of viral RNA of the serum, HCV-RNA was detected using reverse transcriptase-nested polymerase chain reaction (RT-nested PCR) and then HCV genotypes analyzed by restriction fragment length polymorphism (RFLP) assay. RESULTS The mean age of patients was 37.6 ± 14.2 years (range: 1-87). The highest frequency was noted for subtype 1a (44.9%) followed by subtype 3a (39.6%), and 1b (11.3%). Mixed HCV genotypes were also found in 2.5% of the total cases. Subtype 1a was the most frequent genotype in patients over 40 years of age (46.1% versus 42.4%) and subtype 3a was the most frequent in patients under 40 years old (41.5% versus 38.9%). CONCLUSIONS This study suggested that the dominant HCV subtype among Iranian patients was 1a followed by subtype 3a.

Abstract
The prevalence of hepatitis C virus (HCV) genotype 4 has increased throughout Europe. This is an epidemiological study of patients infected chronically with HCV genotype 4 in Denmark. The HCV strains analyzed originated from patient samples collected between 1999 and 2007 as part of the national Danish hepatitis B and C network, DANHEP. Sequence analyses were based on the envelope 1 region of HCV. Results from a total of 72 patients indicated a high degree of genetic heterogeneity. Fifty-six patients (78%) were infected with one of the three dominating subtypes: 4d, 4a, or 4r. The remaining 16 patients (22%) were infected with subtypes 4h, 4k, 4l, 4n, 4o, or 4Unclassified. Three epidemiological profiles were identified: (1) patients infected with HCV by intravenous drug use were infected solely with subtype 4d. They were all of European origin, and 15 of the 16 patients were ethnic Danes. No single transmission event could be confirmed, but the pairwise nucleotide identity within the patients of Danish origin was relatively high (∼95%), suggesting a recent introduction into Denmark. (2) The 21 patients infected with subtype 4a all came from Northern Africa, Egypt, Pakistan, or the Middle East. (3) Patients from Southern Africa dominated among patients infected with subtype 4r (10 of 12 patients). This study demonstrates that HCV genotype 4d has been introduced in and spread among Danish intravenous drug users. The remaining subtypes show restricted distribution, infecting almost exclusively patients from geographical areas with a relatively high prevalence of HCV genotype 4 infections.

Abstract
Hepatitis C virus (HCV) usually evades the host's immune system and persists as a chronic infection. Intravenous drug users (IVDU) represent the majority of patients infected with HCV. Combined therapy of chronic hepatitis C (CHC) with peginterferon alpha-2a and ribavirin can be successful even when patients continue the intravenous drug use. In this study, we compared the characteristics of age, gender, genotype, and stage of fibrosis and the therapy outcome among IVDU and patients with no history of drug use. The study included 69 patients diagnosed with chronic hepatitis C, evaluated and treated at the Clinic for infectious diseases in Nis from 2005 to 2009. HCV RNA was detected by a polymerase chain reaction and the determination of genotypes was undertaken. Liver biopsies were examined histopathologically. Patients received a combined treatment of peginterferon alfa-2a and ribavirin. Therapy efficiency was evaluated based on the achievement of the sustained virological response (SVR). A comparison of characteristics was performed with the use of Mann-Whitney U test, chi-square (chi2) test and logistic regression. IVDU were significantly younger than patients in the control group. Prevalence of stage 1 fibrosis was significantly higher among IVDU. The therapy outcome is influenced by the patient's age and HCV genotypes. Each year added to one patient decreased the therapy efficiency by 8.1%, while genotypes 2 and 3 experienced a therapy which was 2.08 times more efficient than in other cases. IVDU represent a specific population different from non-using patients. However, they can be treated effectively if an adequate patient-doctor relationship is established.

Abstract
BACKGROUND The shift in the distribution of HCV genotypes could have a significant impact on practical medical issues. OBJECTIVES To describe the recent distribution and evolution of HCV genotypes in southwest China. STUDY DESIGN HCV genotypes were determined by nucleotide sequencing of the CE1 regions followed by phylogenic analysis with the published HCV genotype. HCV genotype distribution was analyzed according to patients' age, risk exposure, and the first time of risk exposure. RESULTS Among the 371 cases, subtypes 1a (0.8%), 1b (42.0%), 2a (9.7%), 3a (12.1%), 3b (21.0%), 4a (0.3%), and 6a (14.0%) were found. Genotypes 3 and 6 were significantly more frequent (85.4%) among IDUs than among other subjects (32.5%, P<0.001), they were also more frequent among subjects aged 40 years or under (63.6%) than older patients (21.6%, P<0.001), among patients infected after 1997 (54.4%) than those infected before 1997 (27.3%, P=0.001). Age 40 years or under (P<0.001) and infection via IDU (P<0.001) were independently associated with genotypes 3 and 6 in the multivariate stepwise logistic regression analysis. IDU was detected as a cause of infection in 27.8% of HCV cases; it was more frequent among younger patients (40.4%) than older ones (7.1%, P<0.001), among patients infected after 1997 (40.3%) than those infected before 1997 (16.2%, P<0.001). CONCLUSION In southwest China, the relative prevalence of genotypes 3 and 6 has increased significantly, and that of genotypes 1b and 2a has declined significantly among young patients. This shift in distribution was associated with changes in the modes of HCV acquisition.
