Abstract

Objective High serum HBV DNA levels are associated with high risks of hepatocellular carcinoma (HCC) and cirrhosis in patients with chronic hepatitis B (CHB). Although the immune-tolerant (IT) phase is characterised by high circulating HBV DNA levels, it remains unknown whether antiviral treatment reduces risks of HCC and mortality.

Design This historical cohort study included HBeAg-positive patients with CHB with high HBV DNA levels (≥20 000 IU/mL) and no evidence of cirrhosis at a tertiary referral hospital in Korea from 2000 to 2013. The clinical outcomes of 413 untreated IT-phase patients with normal alanine aminotransferase (ALT) levels (females, <19 IU/mL; males, <30 IU/mL) were compared with those of 1497 immune-active (IA)-phase patients (ALT ≥80 IU/mL) treated with nucleos(t)ide analogues.

Results The IT group was significantly younger than the IA group (mean age, 38 vs 40 years at baseline, p=0.04). The 10-year estimated cumulative incidences of HCC (12.7% vs 6.1%; p=0.001) and death/transplantation (9.7% vs 3.4%; p<0.001) were significantly higher in the IT group than the IA group. In multivariable analyses, the IT group showed a significantly higher risk of HCC (HR 2.54; 95% CI 1.54 to 4.18) and death/transplantation (HR 3.38; 95% CI 1.85 to 6.16) than the IA group, which was consistently identified through inverse probability treatment weighting, propensity score-matched and competing risks analyses.

Conclusions Untreated IT-phase patients with CHB had higher risks of HCC and death/transplantation than treated IA-phase patients. Unnecessary deaths could be prevented through earlier antiviral intervention in select IT-phase patients.

抽象

目的高血清HBV DNA水平与慢性乙型肝炎（CHB）患者肝细胞癌（HCC）和肝硬化风险高有关。虽然免疫耐受（IT）阶段的特点是循环HBV DNA水平高，但是抗病毒治疗是否降低HCC发病风险和死亡率还不清楚。

设计这项历史性队列研究包括2000年至2013年在韩国的一家三级转诊医院的HBeAg阳性CHB患者，其HBV DNA水平高（≥20000 IU / mL），无肝硬化证据。413例未经治疗的IT- （ALT≥80IU/ mL）的1497例正常丙氨酸转氨酶（ALT）水平的患者（女性<19IU / mL;男性<30IU /用核苷（酸）类似物处理。

结果IT组明显比IA组年龄小（平均年龄38岁，基线40岁，p = 0.04）。 IT组的10年估计累积发生率（12.7％比6.1％; p = 0.001）和死亡/移植（9.7％比3.4％; p <0.001）显着高于IA组。在多变量分析中，IT组显示出比IA组显着更高的HCC风险（HR 2.54; 95％CI 1.54至4.18）和死亡/移植（HR 3.38; 95％CI 1.85至6.16）反概率处理加权，倾向分数匹配和竞争风险分析。

结论未经治疗的IT阶段CHB患者HCC和死亡/移植的风险高于治疗的IA阶段患者。在选择的IT阶段患者中通过早期的抗病毒干预可以预防不必要的死亡。

年纪大的DNA水平高也应该抗病毒，抗病毒的利大于弊，减少HCC发生率

逻辑不是很能说明问题，it组应该区分是否抗病毒，内部进行对比。而不是跟ia组比。ia已经激活免疫了，不能说明抗病毒是否降低了hcc几率

回复 neilhbver 的帖子

我认为IT（免疫耐受）组也应该分层年龄组，并进行比较。
这可能确定IT的高风险组.
