摘要:

目的 研究广西扶绥地区乙型肝炎(简称乙肝)患者HBV基因型分布特点,为本地区乙肝的防治及临床抗乙肝感染的治疗提供依据。方法 采用巢式PCR技术对285例(肝癌40例,乙肝病毒携带者245例)扩增HBV S区基因,经测序后与标准序列比对,得出相应的基因型,分析HBV基因型的分布概况及其特点。 结果 在285例患者中,B基因型59例(20.7%),C基因型223例(78.2%),未分型3例(1.1%)。在肝癌和乙肝病毒携带者中,B基因型、C基因型分别为10例(25.00%)、30例(75.00%)和49例(20.25%)、193例(79.75%)(P>0.05);男性B基因型、C基因型分别为40例、158例,女性B基因型、C基因型分别为19例、65例,HBV基因型在男性和女性间的分布差异均无统计学意义(P均>0.05);在<30岁、30~40岁、40~55岁、>55岁各年龄组间HBV基因型的分布差异均无统计学意义(P均>0.05)。 结论 扶绥地区HBV基因型以C基因型占主要优势,其次是B基因型,未见其他分型;HBV基因型在年龄、性别间的分布无明显差异。

Abstract:

Objective To study the genotype distribution of hepatitis B virus (HBV) in patients from the Fusui area of China in order to guide prevention and treatment efforts. Methods A total of 40 patients with liver cancer and 245 HBV carriers were analyzed using nested PCR to amplify the HBV S region. The amplicons were sequenced and analyzed in sequence alignments with published HBV genotypes. Result Of the 285 participants,59(20.7%) were infected with genotype B virus,223(78.2%) with genotype C,and 3 (1.1%) with an undefined genotype. Of the 282 participants with either genotype B or C virus,men accounted for 40 with genotype B and 158 with genotype C;women accounted for 19 with genotype B and 65 with genotype C. The gender distribution was similar for these two genotypes (P>0.05). Among liver cancer patients,10 (25%) had genotype B and 30 (75%) had genotype C;among HBV carriers,49(20.25%) had genotype B and 193(79.75%) had genotype C. Stratification of patients into four age groups (<30 years,30-40 years, 40-55 years,and >55 years),The distribution of these two genotypes was similar in the four age groups(P>0.05). Conclusion HBV genotype C predominates in the Fusui area,followed by genotype B,with no other types observed. Genotypes B and C are distributed similarly among individuals of different age and gender.
