1A comparative review of HLA associations with hepatitis Band C viral infections across global populations显示文摘Hepatitis B (HBV) and hepatitis C (HCV) viral infection or co-infection leads to risk of development of chronic infection, cirrhosis and hepatocellular carcinoma (HCC). Immigration and globalization have added to the challenges of public health concerns regarding chronic HBV and HCV infections worldwide. The aim of this study is to review existing global literature across ethnic populations on HBV and HCV related human leukocyte antigen (HLA) associations in relation to susceptibility, viral persistence and treatment. Extensive literature search was conducted to explore the HLA associations in HBV and HCV infections reported across global populations over the past decade to understand the knowledge status, weaknesses and strengths of this information in different ethnic populations. HLA DR13 is consistently associated with HBV clearance globally. HLADRB1*11/*12 alleles and DQB1*0301 are associated with HBV persistence but with HCV clearance worldwide. Consistent association of DRB1*03 and *07 is observed with HCV susceptibility and non-responsiveness to HBV vaccination across the population. HLA DR13 is protective for vertical HBV and HCV transmission in Chinese and Italian neonates, but different alleles are associated with their susceptibility in these populations. HLA class Ⅰmolecule interactions with Killer cell immunoglobulin like receptors (KIR) of natural killer (NK) cells modulate HCV infection outcome via regulating immune regulatory cells and molecules. HLA associations with HBV vaccination, interferon therapy in HBV and HCV, and with extra hepatic manifestations of viral hepatitis are also discussed. Systematic studies in compliance with global regulatory standards are required to identify the HLA specific viral epitope, stage specific T cell populations interacting with different HLA alleles during disease progression and viral clearance of chronic HBV or HCV infections among different ethnic populations. These studies would facilitate stage specific therapeutic strategies for clearance of HBV and HCV infections or co-infections across global populations and aid in identification of HBV-HCV combined vaccine. HLA associations of chronic HBV or HCV development with confounding host factors including alcohol, drug abuse, insulin resistance, age and gender are lacking and warrant detailed investigation across global populations.Rashmi Singh Rashmi Kaul Anil Kaul Khalid Khan 2007World Journal of Gastroenterology2007,13,12:31

4T29C genotype polymorphism of estrogen receptor alpha is associated with initial response to interferon-alpha therapy in chronic hepatitis B patients显示文摘BACKGROUND:Virological clearance,delayed progression to cirrhosis or liver cancer,and increased survival are the long-term goals of antiviral therapy in chronic hepatitis B patients.Identification of host factors correlated with therapeutic response may contribute greatly to individual treatment.This study aimed at investigating whether T29C genotype polymorphism of estrogen receptor alpha(ESR1) is associated with the initial response to interferon-alpha(IFN-α)therapy in chronic hepatitis B patients.METHODS:The initial responses of 100 patients to IFN-α therapy were evaluated and compared by classifying them into three groups according to T29C genotype polymorphism of ESR1:T/T,T/C,and C/C genotype groups.Polymerase chain reaction-restriction fragment length polymorphism was used to analyze the genotype polymorphism in T29C.RESULTS:The frequency of initially combined response was markedly higher in both the T/T and T/C groups than in the C/C group(Z=10.326,P=0.006 and Z=26.247,P=0.000, respectively).In addition,the initial virological response was higher in the T/T and T/C groups than the C/C group(χ2=5.674, P=0.017 andχ2=4.980,P=0.026,respectively).In 78 initially HBeAg-positive patients,however,the frequency of initial e-antigen disappearance or seroconversion among the T/T,T/C, and C/C genotype groups was 34.15%,27.78%and 15.79%, respectively,which were not significantly different.CONCLUSION:The T29C genotype polymorphism of ESR1 is associated with the initial response to IFN-αin patients with chronic hepatitis B,and might be a significant marker for predicting the initial response to IFN-α,at least in this study population.Zhang, Ting-Ting Zhang, Zhen-Hua Gao, Yu-Feng Zhang, Ya-Fei Yang, Dong-Liang Li, Xu 2010Hepatobiliary & Pancreatic Diseases International2010,9,3:4
5YMDD耐药变异与HLA位基因多态性的相关性显示文摘目的:初步探讨慢性乙型肝炎(CHB)患者拉米夫定治疗中YMDD变异与HLA-A,B,DRB1各位点等位基因分布频率的相关性.方法:对142例CHB患者,采用荧光标记杂交双探针PCR融解曲线法(FH-PCR-MC)检测血浆HBV YMDD变异;对其56例患者的外周血白细胞,采用序列特异性引物/聚合酶链式反应(PCR—SSP)技术检测人类白细胞表面抗原等位基因(HLA—A,B,DRB1)分型.结果:在用拉米夫定治疗的142例CHB患者中,YMDD变异率为56.3%.HLA—B*58和DRB1*03等位基因分布频率在YMDD变异组与YMDD野生组比较有显著性降低(0.013 vs 0.094.P=0.036;0.000 vs 0.063.P=0.024);HLA—A*30等位基因分布频率在YIDD组明显增高,与YVDD组比较差异显著(0.158 vs 0.024,P=0.034);HLA—A*33等位基因分布频率在YVDD变异组明显增高,与YIDD变异组比较差异显著(0.119 vs 0.000,P=0.028).结论:YMDD耐药变异与HLA等位基因多态性有一定相关性.携有HLA—B*58和DRB1*03等位基因的个体感染的HBV可能不易发生YMDD变异:携有HLA—A*30等位基因的个体感染的HBV可能易发生YIDD变异:携有HLA—A*33等位基因的个体感染的HBV可能易发生YVDD变异.张淑云 李兴库 董广璐 仰曙芬 谷鸿喜 李迪 金茜 刘伟 杜博 卢滨 2006世界华人消化杂志2006,14,29:3
6雌激素受体α基因PvuⅡ多态性与慢性乙型肝炎患者干扰素-α早期应答的相关性研究显示文摘目的探讨雌激素受体α基因PvuⅡ多态性与慢性乙型肝炎患者干扰素治疗发生早期应答的相关性。方法采用聚合酶链反应-限制性片段长度多态性法检测100例首次接受干扰素治疗的慢性乙型肝炎患者外周血雌激素α受体基因PvuⅡ多态性,并分析了基因型与干扰素早期应答的相关性。结果在雌激素受体基因PvuⅡ的PP、Pp和pp三个基因型间,PP基因型患者早期病毒学应答率(70.8%)明显高于Pp(40.0%)和pp(37.2%)基因型,差异具有统计学意义(P<0.05),但早期联合应答率和早期HBeAg血清转换率在PP、Pp和pp三种基因型间的差异均无统计学意义(P>0.05)。结论研究提示PvuⅡ多态性检测可能是预测慢性乙型肝炎患者干扰素-α治疗后早期应答率的重要因素之一。张婷婷 张振华 叶珺 张亚飞 张玲 夏国美 李旭 2010实用肝脏病杂志2010,13,4:3
7中国部分汉族人群中IL-6基因启动子-572G/C多态性与HBV感染易感性的关系显示文摘目的:探讨中国人群中IL-6基因启动子中单核苷酸多态性与HBV感染的遗传易感性关联.方法:提取160例HBV感染者及212例健康献血者外周血基因组DNA,用PCR-RFLP方法检测两组人群中G-174C、G-572C和G-597A三个多态性位点的基因型.性别、吸烟、饮酒以及Hardy-Weinberg等采用Chi-square Test检测,多态性与HBV感染者风险关联及亚组关联的统计学分析采用非条件Logistic回归并同时校正混杂因素.结果:PCR-RFLP检测结果显示:IL-6基因启动子中G-174C和G-597A两个位点在中国人群中不存在多态性,而G-572C处的多态性在人群中普遍存在,其多态性位点等位基因频率分布符合Hardy-Weinberg平衡定律.统计分析表明该位点的多态性在两组人群中有明显的差异(G/C vs G/G,OR=2.65,P<0.05;C/C vs G/G,OR=3.31,P<0.05);亚组分析中表明<30岁的年龄组中差异显著(G/G vs G/C或C/C,OR=16.92,P<0.05).结论:在中国汉族人群中,IL-6基因启动子中-572处的多态性对于乙型肝炎的发生有着显著的易患关系,同时年龄对于这种易感关联有着协同作用.戴悦 刘晓琳 柴庆波 盖郁慧 李岩 刘宝国 2009世界华人消化杂志2009,17,15:2
