年轻人的肝细胞恶性肿瘤是南部非洲乙型肝炎病毒(HBV)感染的一个突出特征。在此,我们报告了一项关于赞比亚 HBV 感染成人的肝脏病理学与生物标志物相关的横断面研究。我们分析了赞比亚持续性 HBV 感染患者的肝活检。我们分析了 104 名 HBV 感染和肝病证据的患者。我们对 53 名成人进行了肝脏活检;其中,12 例 (23%) 乙型肝炎 e 抗原血清呈阳性。基因型均匀分布在 A 和 E 之间。一次活检显示恶性肿瘤。 52 例活检中,有 11 例 (21%) 没有恶性肿瘤,其中 11 例为 3 期或以上,50 例 (94%) 中发现小叶炎症。丙氨酸氨基转移酶 (ALT) 和 γ-谷氨酰转移酶:血小板比率 (GPR) 均与疾病阶段无关,但与 Ishak 总分相关(分别为 ρ=0.47,p=0.0004 和 ρ=0.33,p=0.02)。在 11 例纤维化 3 期或以上的活检中,有 10 例观察到大细胞变化,在 41 例早期疾病的活检中,有 16 例观察到大细胞变化 (p=0.005)。与没有大细胞改变的患者(1.7 [IQR 1.0–2.8];p=0.03)相比,有大细胞改变的患者(中位数 3.6 [四分位距 {IQR} 1.6–5.1])的血清甲胎蛋白升高,但仍在正常范围内。 ALT 和 GPR 都不能预测大的细胞变化。在赞比亚感染乙型肝炎病毒的年轻成年人中,大细胞变化很常见。仅血清甲胎蛋白被确定为该表型的生物标志物。
Hepatocellular malignancy in young adults is a prominent feature of hepatitis B virus (HBV) infection in southern Africa. Here we report a cross-sectional study of liver pathology correlated with biomarkers in adults with HBV infection in Zambia. We analysed liver biopsies from Zambian patients with persistent HBV infection. We analysed 104 patients with HBV infection and evidence of liver disease. We obtained liver biopsies from 53 adults; of these, 12 (23%) were hepatitis B e antigen seropositive. The genotype was evenly distributed between A and E. One biopsy showed malignancy. Stage was 3 or more in 11 of 52 (21%) biopsies free of malignancy and lobular inflammation was found in 50 (94%). Neither alanine aminotransferase (ALT) nor the γ-glutamyl transferase:platelet ratio (GPR) were correlated with the stage of disease but were correlated with total Ishak score (ρ=0.47, p=0.0004 and ρ=0.33, p=0.02, respectively). Large cell change was observed in 10 of 11 biopsies with fibrosis stage 3 or more and 16 of 41 with early disease (p=0.005). Serum α-fetoprotein was elevated, although still within the normal range, in patients with large cell change (median 3.6 [interquartile range {IQR} 1.6–5.1]) compared with those without (1.7 [IQR 1.0–2.8]; p=0.03). Neither ALT nor GPR predicted large cell change. Large cell change was common in young HBV-infected adults in Zambia. Only serum α-fetoprotein was identified as a biomarker of this phenotype.
