摘要
背景：尼日利亚仍然是非洲乙型肝炎病毒（HBV）负担较重的国家之一。有报告显示，尼日利亚存在混合型 HBV 基因型；然而，有关混合型基因型感染的数据仍然很少，尤其是在尼日利亚南部地区：我们的目的是确定尼日利亚伊巴丹大学学院医院 HBsAg 阳性肠胃病患者的 HBV 基因型分布情况：用 ELISA 对血清样本进行 HBsAg 检测，并用半嵌合多重 PCR 对阳性样本进行 HBV 基因型 A、B、C、D、E 和 F 的基因分型：用 R-studio 对生成的数据进行分析。共有 81/90 份（90%）HBsAg 阳性样本成功进行了基因分型，其中基因型 A 的感染率最高，为 15.7%，而基因型 B 和 E 的感染率最低，分别为 1.2%。在混合感染中，基因型 A/C 感染率最高，达 40%，而基因型 A/D 混合感染率最低，仅为 4.8%：我们主张在尼日利亚更大规模的队列中进行全面的基因型分析，以便更全面地了解不同 HBV 基因型在整个人群中的分布和流行情况。
Molecular detection and genotyping of HBV from HBsAg positive patients in a tertiary hospital in Nigeria.
Background: Nigeria remains one of the countries with a high hepatitis B virus (HBV) burden in Africa. Reports have indicated the presence of mixed HBV genotypes in Nigeria; however, there is still paucity of data regarding mixed genotype infections particularly in the Southern part of the country.
Objective: Our aim is to determine the HBV genotype distribution among HBsAg-positive gastroenterology patients at the University College Hospital Ibadan, Nigeria.
Method: Serum samples were screened for HBsAg by ELISA, and positive samples were genotyped by semi-nested multiplex PCR for HBV genotypes A, B, C, D, E and F.
Results: Data generated were analyzed in R-studio. A total of 81/90 (90%) of HBsAg-positive samples were successfully genotyped, and genotype A was most prevalent with 15.7%, while genotypes B and E were the least with 1.2% each. Genotypes A/C infection was the highest among mixed infections with 40% prevalence, while genotypes A/D were the least prevalent mixed infection with 4.8%.
Conclusion: We advocate for a comprehensive genotype analysis in larger cohorts across Nigeria, to give a more comprehensive understanding of the distribution and prevalence of different HBV genotypes population wide.
