| 1 | Hepatitis C virus genotype 6:Virology,epidemiology,genetic variation and clinical implication显示文摘Hepatitis C virus(HCV)is a serious public health problem affecting 170 million carriers worldwide.It is a leading cause of chronic hepatitis,cirrhosis,and liver cancer and is the primary cause for liver transplantation worldwide.HCV genotype 6(HCV-6)is restricted to South China,South-East Asia,and it is also occasionally found in migrant patients from endemic countries.HCV-6 has considerable genetic diversity with23 subtypes(a to w).Although direct sequencing followed by phylogenetic analysis is the gold standard for HCV-6 genotyping and subtyping,there are also now rapid genotyping tests available such as the reverse hybridization line probe assay(INNO-LiPAⅡ;Innogenetics,Zwijnaarde,Belgium).HCV-6 patients present with similar clinical manifestations as patients infected with other genotypes.Based on current evidence,the optimal treatment duration of HCV-6 with pegylated interferon/ribavirin should be 48 wk,although a shortened treatment duration of 24 wk could be sufficient in patients with low pretreatment viral load who achieve rapid virological response.In addition,the development of direct-acting antiviral agents is ongoing,and they give high response rate when combined with standard therapy.Herein,we review the epidemiology,classification,diagnosis and treatment as it pertain to HCV-6. | Vo Duy Thong Srunthron Akkarathamrongsin Kittiyod Poovorawan Pisit Tangkijvanich Yong Poovorawan | 2014 | World Journal of Gastroenterology2014，20，11： | 4 |

| 3 | Early viral kinetics during hepatitis C virus genotype 6 treatment according to IL28B polymorphisms显示文摘AIM:To investigate the early viral kinetics and interleukin-28B(IL28B)polymorphisms of hepatitis C genotype6 during pegylated interferon and ribavirin therapy.METHODS:Sixty-five patients with chronic hepatitis C virus(HCV)infection treated with pegylated interferon and ribavirin(PEG-IFN/RBV)were included,of whom15(23.1%),16(24.6%)and 34(52.3%)patients were infected with hepatitis C genotype 1(HCV-1),genotype3(HCV-3)and genotype 6(HCV-6),respectively.Serum HCV-RNA levels were measured frequently during the first 4-wk of therapy.DNA extracted from samples was analyzed for the IL28B single nucleotide polymorphism(SNP)rs12979860 by polymerase chain reaction and direct sequencing.RESULTS:During the first 4-wk of therapy,the mean viral decline for patients with HCV-6(5.55±1.82 log10IU/mL)was comparable to that of patients with HCV-3(5.55±1.82 log10IU/mL vs 5.86±1.02 log10IU/mL,P=0.44)and was significantly higher than patients with HCV-1(5.55±1.82 log10IU/mL vs 4.23±1.99 log10IU/mL,P=0.04).In the HCV-6 group,the first phase(days 0-2)viral decline was significantly higher in patients with the favorable rs12979860 CC than non-CC genotypes(2.46±1.01 log10IU/mL/wk vs 1.70±0.67 log10IU/mL,respectively,P=0.045).A statistically insignificant decrease in the second-phase(days 7-28)decline was also found in patients with the CC genotype than those with the non-CC genotype,though not significantly different(1.24±0.64 log10IU/mL/wk vs 0.80±0.65 log10IU/mL/wk,respectively,P=0.172).At baseline,the SNP genotype was an independent predictor of rapid virological response but not of sustained virological response.CONCLUSION:The IL28B genotype was linked to an impact on early viral kinetics in response to PEG-IFN/RBV therapy in HCV-6 infected patients. | Srunthron Akkarathamrongsin Sunchai Payungporn Vo Duy Thong Kittiyod Poovorawan Phisit Prapunwattana Yong Poovorawan Pisit Tangkijvanich | 2014 | World Journal of Gastroenterology2014，20，30： | 0 |
