摘要
背景:宿主免疫系统在乙型肝炎病毒(HBV)感染表现中起重要作用。几种炎症细胞因子的遗传多态性，包括TNF-α和IL-10，与慢性乙型肝炎(CHB)的进展有关，尽管结果相互矛盾。慢性乙型肝炎的进展可分为四个阶段:免疫耐受(IT)、免疫清除(IC)、低/无复制(LR)和e阴性肝炎(ENH)，其中HBeAg血清转化是一个重要的里程碑。在这里，我们确定了TNF-α (rs1800629)和IL-10 (rs1800896和rs1800872) snp在印度尼西亚CHB患者CHB自然病程进展中的相关性，特别是与HBeAg血清转化的相关性。方法:共招募287名受试者，并根据HBeAg、病毒载量和ALT水平将其分为不同的CHB期。采用PCR-RFLP检测TNF-α和IL-10 snp，并直接测序确认。SNP基因型与CHB动力学之间的关系采用95% CI的优势比(OR)来确定。结果:在所有基因模型中，IL-10 -592A/C多态性与IT和IC向LR期、IT和IC向ENH期、LR向ENH期进展均无显著相关性。IL-10 rs1800896和TNF-α rs1800629不能用logistic回归分析。受试者年龄(≥40岁)与IT和IC / LR (OR: 2.191, 95% CI 1.067-4.578, P = 0.034)、IT和IC / ENH (OR: 7.460, 95% CI 3.316-18.310, P < 0.001)、LR / ENH (OR: 5.252, 95% CI 2.010-14.858, P = 0.001)显著相关。男性与LR和ENH相关(OR: 4.077, 95% CI 1.605-11.023, P = 0.004)。结论:年龄和男性性别与CHB期进展相关，而不是TNF-α和IL-10多态性。研究宿主决定因素和病毒因素对慢性乙型肝炎病毒期进展的影响，有助于了解慢性乙型肝炎病毒期进展的机制。
Host Factors in the Natural History of Chronic Hepatitis B: Role of Genetic Determinants.
Background: The host immune system plays an important role in hepatitis B virus (HBV) infection manifestation. Genetic polymorphisms of several inflammatory cytokines, including TNF-α and IL-10, have been associated with chronic hepatitis B (CHB) progression, although with contradicting results. CHB progression can be categorized into four phases, immune tolerance (IT), immune clearance (IC), low/no replicative (LR), and e-negative hepatitis (ENH), with HBeAg seroconversion as an important milestone. Here, we determined the association of TNF-α (rs1800629) and IL-10 (rs1800896 and rs1800872) SNPs in the context of CHB natural history progression, particularly to HBeAg seroconversion, in Indonesian CHB patients.
Methods: A total of 287 subjects were recruited and categorized into distinct CHB phases based on HBeAg, viral load, and ALT levels. TNF-α and IL-10 SNPs were determined using PCR-RFLP and confirmed with direct sequencing. The association between SNP genotypes with CHB dynamics was determined using logistic regression presented as odds ratio (OR) with 95% CI.
Results: No significant association was found between IL-10 -592A/C polymorphism and progression of IT and IC to LR, IT and IC to ENH, and LR to ENH phases in all the gene models. IL-10 rs1800896 and TNF-α rs1800629 could not be analyzed using logistic regression. Subjects' age (≥40 years old) was significantly associated with IT and IC to LR (OR: 2.191, 95% CI 1.067-4.578, P = 0.034), IT and IC to ENH (OR: 7.460, 95% CI 3.316-18.310, P < 0.001), and LR to ENH (OR: 5.252, 95% CI 2.010-14.858, P = 0.001). Male gender was associated with LR to ENH (OR: 4.077, 95% CI 1.605-11.023, P = 0.004).
Conclusions: Age and male gender were associated with CHB phase progression instead of the TNF-α and IL-10 polymorphisms. It would be beneficial to study not only the effect of host determinants but also the viral factor to understand the mechanisms of CHB phase progression.
