对于联合治疗,想象和猜测没有多大意义,得靠临床数据说话。
对于ETV+IFN,数据是现成的,类似的最新临床数据还有很多,就不多重复了。郭教授文中所引用的相关数据,大致是比较老旧的,受到先前实验设计和样本量的限制,眼下已经没有太多的参考价值了,认识总是在不断进步的。

Abstract
Entecavir (ETV) is a potent inhibitor of hepatitis B viral replication, but long-term therapy may be required. We investigated whether adding on pegylated interferon (Peg-IFN) to ETV therapy enhances serological response rates. In this global investigator-initiated, open-label, multicenter, randomized trial, hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients with compensated liver disease started on ETV monotherapy (0.5 mg/day) and were randomized in a 1:1 ratio to either Peg-IFN add-on therapy (180 µg/week) from week 24 to 48 (n = 85) or to continue ETV monotherapy (n = 90). Response was defined as HBeAg loss with HBV DNA <200 IU/mL at week 48. Responders discontinued ETV at week 72. All patients were followed until week 96. Response was achieved in 16 of 85 (19%) patients allocated to the add-on arm versus 9 of 90 (10%) in the monotherapy arm (P = 0.095). Adjusted for HBV DNA levels before randomized therapy, Peg-IFN add-on was significantly associated with response (odds ratio: 4.8; 95% confidence interval: 1.6-14.0; P = 0.004). Eleven (13%) of the add-on-treated patients achieved disease remission after ETV cessation versus 2 of 90 (2%) of those treated with monotherapy (P = 0.007), which was 79% (11 of 14) versus 25% (2 of 8) of those who discontinued ETV (P = 0.014). At week 96, 22 (26%) patients assigned add-on versus 12 (13%) assigned monotherapy achieved HBeAg seroconversion (P = 0.036). Peg-IFN add-on led to significantly more decline in hepatitis B surface antigen, HBeAg, and HBV DNA (all P < 0.001). Combination therapy was well tolerated.
CONCLUSION: Although the primary endpoint was not reached, 24 weeks of Peg-IFN add-on therapy led to a higher proportion of HBeAg response, compared to ETV monotherapy. Add-on therapy resulted in more viral decline and appeared to prevent relapse after stopping ETV. Hence, Peg-IFN add-on therapy may facilitate the discontinuation of nucleos(t)ide analogs.

而对于其他联合治疗方案,我之前也提到过,多靶点会有其优势,尤其是联合抑制病毒复制+抑制HBsAg+增强天然及特异性免疫反应或直接杀伤被感染细胞的策略,会有较大成功的希望。但这一切都得经受最基本的动物实验乃至临床实验的检验而非想当然。若是仅仅按照理论和猜想来,HBV早就被攻克了,又怎么会遭遇一次又一次的失败呢?这个道理很简单,但并不是所有人都能很容易的接受,人性使然吧。
