Abstract

OBJECTIVES

To investigate hepatitis C virus (HCV) genotype distribution detected in West China Hospital of Sichuan University.

METHODS

We analyzed genotype distribution data on HCV infected patients who had information of HCV genotypes from January 2009 to December 2013 diagnosed in West China Hospital of Sichuan University.

RESULTS

Five genotypes and 15 genetic subtypes of HCV were found among the 1 998 cases, and 4 of the patients were infected with mixed HCV subtype. Among those genotypes and genetic subtypes, genotype 1a was detected in 8 cases (0.40%), genotype 1b in 1 368 cases (68.47%), genotype 1c in 18 cases (0.90%), genotype 2a in 78 cases (3.90%), genotype 2b in 1 case (0.05%), genotype 2i in 16 cases (0.80%), genotype 3a in 291 cases (14.56%), genotype 3b in 154 cases (7.71%), genotype 3k in 4 cases (0.20%), genotype 5a in 1 case (0.05%), genotype 6a in 50 cases (2.50%), genotype 6b in 3 cases (0.15%), genotype 6h in 1 case (0.05%), genotype 6n in 1 case (0.05%), mixed-genotype 1b/1c in 1 case (0.05%), mixed-genotype 1b/6h in 1 case (0.05%), mixed-genotype 2c/2a in 1 case (0.05%), and mixed-genotype 3b/3k in 1 case (0.05%). The distribution of five main HCV genetic subtypes on gender had no statistical significance (>0.05), and its distribution on people with different ages had statistical significance ( <0.05).

CONCLUSIONS

The major genotypes of HCV were 1b (predominant), 3a, 3b, 2a, 6a in patients diagnosed in West China Hospital of Sichuan University, with the existence of single-genotype 1a, 1c, 2b, 2i, 3k, 5a, 6b, 6h, 6n and mixed-genotype 1b/1c, 1b/6h, 2c/2a, 3b/3k, indicating the diversity of HCV genotype.

摘要

目的

调查四川大学华西医院检测到的丙型肝炎病毒(HCV)基因型分布情况。

方法

我们分析了2009年1月至2013年12月在四川大学华西医院确诊的HCV感染患者中具有HCV基因型信息的基因型分布数据。

结果

在1998例患者中发现了HCV的5种基因型和15种基因亚型,其中4例患者感染了混合HCV亚型。在这些基因型和基因亚型中,1a基因型8例(0.40%),1b基因型1368例(68.47%),1c基因型18例(0.90%),2a基因型78例(3.90%),2b基因型1例(0.05%),2i基因型16例(0.80%),3a基因型291例(14.56%),3b基因型154例(7.71%),3k基因型4例(0.20%),5a基因型1例(0.05%),6a基因型50例(2.50%),6b基因型3例(0.15%),6h基因型1例(0.05%),6n基因型1例(0.05%),1b/1c混合基因型1例(0.05%),1b/6h混合基因型1例(0.05%),2c/2a混合基因型1例(0.05%),3b/3k混合基因型1例(0.05%)。HCV五种主要基因亚型在性别上的分布无统计学意义(>0.05),在不同年龄人群中的分布有统计学意义(<0.05)。

结论

四川大学华西医院确诊患者中HCV的主要基因型为1b(占主导)、3a、3b、2a、6a,存在单基因型1a、1c、2b、2i、3k、5a、6b、6h、6n以及混合基因型1b/1c、1b/6h、2c/2a、3b/3k,表明HCV基因型具有多样性。
