摘要: 目的通过观察慢性HBV感染孕妇替比夫定治疗前后血清Th1/Th2型细胞因子水平变化,探讨替比夫定阻断HBV母婴传播的免疫机制。方法对2008年4月至2012年9月收治的HBeAg阳性慢性HBV感染孕妇54例进行回顾分析,根据ALT水平分为免疫活化组(n=18)和免疫耐受组(n=36),于妊娠中晚期给予替比夫定600 mg/d,常规检测治疗前、分娩前血清ALT、TBil、HBV DNA水平及HBV标志物变化情况,酶联免疫吸附测定法检测Th1型细胞因子[白细胞介素(IL)2、干扰素(IFN)γ]和Th2型细胞因子(IL-4、IL-6)水平。正态分布的计量资料采用t检验,非正态分布的采用非参数检验。以Bivariate分析两变量相关性,用Pearson相关系数表示相关性。结果替比夫定治疗后血清HBV DNA水平明显下降(P<0.01),ALT、TBil水平均无显著变化,无HBeAg血清学转换。相较于健康人群,2组在治疗前和分娩前均表现为IL-2(健康人群<4 pg/ml)和IFNγ(健康人群<15 pg/ml)高表达,而IL-4(健康人群<10 pg/ml)和IL-6...Abstract: Objective To evaluate the changes in serum levels of Th1 /Th2 cytokines in pregnant women with chronic hepatitis B virus ( HBV) infection after telbivudine treatment and to investigate the immune mechanism by which telbivudine blocks the mother- to- infant transmission of HBV. Methods Fifty- four HBeAg- positive pregnant women with chronic HBV infection were enrolled from April 2008 to September 2012, and they were divided into two groups based on their alanine aminotransferase ( ALT) levels: immune active group ( n =18) and immune tolerant group ( n = 36) . Telbivudine was administrated at a dose of 600 mg per day during the second or third trimester.Before treatment and prior to delivery, the serum levels of ALT, total bilirubin ( TBil) , HBV DNA, and HBV markers were routinely measured, and the levels of Th1 cytokines ( interleukin- 2 ( IL- 2) , interferon- γ ( IFNγ) ) and Th2 cytokines ( interleukin- 4 ( IL- 4) , interleukin- 6 ( IL- 6) ) were determined by enzyme- linked immunosorbent assay. SPSS 18. 0 was used for statistical analysis. Results After treatment, HBV DNA level was reduced significantly ( P < 0. 01) , while there were no significant changes in serum ALT and TBil and no HBeAg seroconversion. Compared with the healthy population, before treatment and prior to delivery, both treatment groups showed higher expression of IL- 2 ( healthy control < 4 pg /ml) and IFNγ ( healthy control < 15 pg /ml) but lower expression of IL- 4 ( healthy control< 10 pg /ml) and IL- 6 ( healthy control < 5 pg /ml) . Furthermore, there were no significant differences in IL- 2, IFNγ, IL- 4, and IL-6 levels between the two groups ( P > 0. 01) . Prior to delivery, IL- 4 level was elevated in immune active group ( P = 0. 014) , but within the limits of normal range, while IL- 2, IFNγ, and IL- 6 levels showed no significant changes ( P = 0. 182, 0. 259, and 0. 710, respectively) ; the levels of IL- 2, IFNγ, IL- 4, and IL- 6 in immune tolerant group showed no significant changes ( P = 0. 651, 0. 839, 0. 650, and 0. 542, respectively) . Conclusion Th1 cytokines are highly expressed while Th2 cytokines are lowly expressed in the second or third trimester among HBV- infected pregnant women. Short- term telbivudine treatment has limited influence on Th1 /Th2 balance in HBV- infected pregnant women, indicating that other mechanisms might be recruited for interfering with the mother- infant transmission of HBV.
