摘要: 目的 观察应用α干扰素(IFN-α)治疗慢性乙型肝炎(CHB)儿童的疗效,并分析影响疗效的因素。方法 2013年3月~2016年3月我科诊治的CHB患儿70例,随机分为两组,40例患儿接受α-干扰素治疗6个月,另30例患儿接受胸腺肽注射液治疗6个月。在治疗结束时,比较两组患儿血清丙氨酸氨基转移酶(ALT)复常率、HBsAg、HBeAg和HBV DNA转阴率,并分析影响CHB患儿治疗应答的因素。结果 在治疗结束时,α-干扰素治疗患儿血清ALT复常率为97.5%,与胸腺肽治疗患儿的93.3%比,无显著性相差(P>0.05),而血清HBeAg转阴率为40.0%,血清HBV DNA转阴率为77.5%,均显著高于胸腺肽治疗组患儿的10.0%和3.3%(x2=7.802,x2=37.998,P<0.05);对α-干扰素治疗患儿的治疗应答进一步分析显示,30例血清ALT水平大于200 u/l者血清HBeAg转阴率和HBV DNA转阴率分别为46.7%和43.3%,显著高于10例血清ALT水平<200 U/L患者的10.0%和10. 0%(P<0.05);32例年龄>5岁患儿血清HBeAg转阴率和HBV DNA转阴率分别为53.1%和50.0%,显著高于8例年龄<5岁患儿的12.5%和12.5%(P<0.05);31例血清HBV DNA水平<6 lg copies/ml者血清HBeAg转阴率和HBV DNA转阴率分别为54.8%和61.3%,显著高于9例血清HBV DNA水平>6 lg copies/ml患儿的11.1%和22.2%(P<0.05),而21例男性患儿血清HBeAg转阴率和HBV DNA转阴率分别为33.3%和28.6%,与19例女性患儿的47.4%和47.4%比,无显著性差异(P>0.05),5例病程<1年患儿血清HBeAg转阴率和HBV DNA转阴率分别为80.0%和60.0%,与35例病程>1年患儿的45.7%和48.5%比,也无显著性差异(P>0.05)。结论 应用IFN-α治疗CHB儿童有一定的近期疗效,但存在明显的不良反应,其疗效与患儿年龄、血清ALT和HBV DNA水平有关,值得进一步探讨。

Abstract: Objectiv To investigate the predictive factors of response to interferon-α(IFN-α) antiviral therapy in children with chronic hepatitis B (CHB). Methods 70 children with CHB were recruited in our hospital between March 2013 and March 2016,and were randomly divided into IFN-α-treated (n=40) and thymopeptide-treated group (n=30). All patients were treated for six months. Serum alanine aminotransferase (ALT) normalization rates,the negative rates of serum HBeAg and the negative rates of serum hepatitis B virus deoxyribonucleic acid(HBV DNA) were compared between the two groups. Results At the end of the regimen,serum ALT normalization rate in IFN-α-treated group was 97.5%,not significantly different compared to 93.3% in thymopeptide-treated group (P>0.05),while serum HBeAg negativity rate was 40.0% and serum HBV DNA loss was 77.5%,both much higher than 10.0% and 3.3% (x2=7.802,x2=37.998,P<0.05) in thymopeptide-treated group;our further analysis about the response of IFN-αshowed that serum HBeAg and HBV DNA negativity rates in 30 children with serum ALT levels greater than 200 u/l were 46.7% and 43.3%,significantly higher than 10.0% and 10.0% (P<0.05) in 10 children with serum ALT levels less than <200 U/L;serum HBeAg and HBV DNA negativity rates in 32 children older than 5 years were 53.1% and 50.0%,significantly higher than 12.5% and 12.5%,respectively(P<0.05) in 8 children younger than 5 years;serum HBeAg and HBV DNA negativity rates in 31 children with serum HBV DNA levels greater than <6 lg copies/ml were 54.8% and 61.3%,significantly higher than 11.1% and 22.2%,respectively(P<0.05) in 9 children with serum HBV DNA levels greater than 6 lg copies/ml,while serum HBeAg and HBV DNA negativity rates in 21 boy were 33.3% and 28.6%,not significantly different compared to 47.4% and 47.4%,respectively(P>0.05) in 19 girls,and serum HBeAg and HBV DNA negativity rates in 5 children with less than one year illness period were 80.0% and 60.0%,not significantly different compared to 45.7% and 48.5%,respectively (P>0.05) in 35 children with disease period longer than one year. Conclusion IFN-α is in short-term effective for the treatment of children with CHB, but the incidence of adverse reactions are common,which warrants further investigation.
