Abstract
BACKGROUND & AIMS:
Recent studies suggest that hepatitis B virus (HBV) genotype B is associated with less active liver disease than HBV genotype C. The aim of our study was to determine if HBV genotype B is associated with higher rates of spontaneous hepatitis B e antigen (HBeAg) seroconversion compared with genotype C.
METHODS:
A retrospective study using stored sera from 332 Chinese patients with chronic HBV infection followed for a mean of 48 months (range, 12-98) were tested for HBV genotype using a line-probe assay.
RESULTS:
HBV DNA was detected in 273 patients, 122 had HBV genotype B and 147 genotype C. Patients with genotype B had a significantly lower prevalence of HBeAg at presentation and significantly higher rates of spontaneous HBeAg seroconversion during follow-up. HBV genotype B patients who were HBeAg positive were significantly younger, and spontaneous HBeAg seroconversion occurred approximately 1 decade earlier compared with HBV genotype C patients. Multivariate analyses identified high alanine aminotransferase (baseline and follow-up), age >30 years, and genotype B as independent factors associated with spontaneous HBeAg seroconversion.
CONCLUSIONS:
HBV genotype B is associated with earlier HBeAg seroconversion than genotype C. This finding may explain the less active/progressive liver disease in patients with genotype B.

抽象
背景和目的:
最近的研究表明,乙型肝炎病毒(HBV)基因型B与HBV基因型C相关的活动性较低的肝脏疾病。本研究的目的是确定乙型肝炎病毒基因型是否与自发性乙型肝炎e抗原(HBeAg)血清转换与基因型C比较
方法:
一项回顾性研究利用线性探针法检测了332名中国慢性乙型肝炎病毒感染者血清储存的平均时间为48个月(范围12-98)的血清HBV基因型。
结果:
乙型肝炎病毒DNA检测273例,122例乙型肝炎病毒基因型乙型和147基因型C.基因型乙型肝炎患者HBeAg显着降低,在随访期间显着更高的自发HBeAg血清转换率。 HBV基因型B患者HBeAg阳性率显着较低,与HBV基因型C患者相比,自发性HBeAg血清转换发生时间早十年左右。多变量分析发现高丙氨酸转氨酶(基线和随访),年龄> 30岁,基因型B是与自发性HBeAg血清学转换相关的独立因素。
结论:
HBV基因型B与早期HBeAg血清学转换相比基因型C相关。这一发现可以解释基因型B患者的活动性/进行性肝脏疾病活动/进展性较低。
结论:
