目的:分析HIV 感染者CD4n +T淋巴细胞（CD4）水平对乙肝疫苗免疫应答的影响，探讨不同CD4水平的HIV感染者乙肝疫苗免疫效果及其持久性，为优化HIV感染者乙肝疫苗免疫策略提供理论支持。n 方法:以2014年广西壮族自治区CDC和宁明县CDC管理的参加0-1-6月20 μg和60 μg乙肝疫苗接种随机对照试验的182名HIV感染者为研究对象，在首针接种后6个月和全程接种后1个月、6个月、1年和3年时，采集研究对象静脉血5 ml，并采用化学发光微粒子免疫分析方法定量检测乙肝表面抗体（抗-HBs）。本研究在既往研究基础上，着重分析不同CD4水平下乙肝疫苗接种后的免疫效果及持久性。结果:CD4<350个/μl的HIV感染者乙肝疫苗全程接种后1个月时，抗-HBs几何平均浓度（GMC）为442.50 mIU/ml，抗-HBs阳性率为71.05%（27/38），强阳性率为44.74%（17/38），明显低于CD4≥350个/μl者［583.90 mIU/ml、92.13%（117/127）和77.95%（99/127）］（n P<0.05）；多因素分析结果显示，控制混杂因素后，CD4<350个/μl者乙肝疫苗抗-HBs阳性的概率是CD4≥350个/μl者的0.14倍（95%n CI：0.03~0.62），CD4水平较低是乙肝疫苗无应答的危险因素。全程接种后6个月到3年时，CD4<350 个/μl者抗-HBs GMC（195.00~27.55 mIU/ml比300.10~45.81 mIU/ml）、阳性率（56.67%~36.67%比78.57%~51.58%）和强阳性率（33.33%~6.67% 比44.64%~15.79%）不同程度下降，且均低于CD4≥350个/μl者。n 结论:CD4<350个/μl的HIV感染者乙肝疫苗无应答风险高，免疫持久性较差，应定期监测HIV感染者抗-HBs水平，并特别关注CD4<350个/μl者，抗-HBs阴性时应尽早全程及加强接种乙肝疫苗。“,”Objective:To explore the immunogenicity and persistence of hepatitis B vaccine in HIV-infected patients with different CD4n +T cell (CD4) levels, and analyze the influence effect of CD4 levels on immunization response.n Methods:A total of 182 HIV-infected patients who participated in a randomized controlled trial of 20 μg and 60 μg hepatitis B vaccination at month 0, 1, and 6 in 2014 by Guangxi Zhuang Atonomous Region CDC and Ningming county CDC were surveyed. Six months later after the first dose and 1 month, 6 months, 1 year, and 3 years later after the full course of the vaccination, 5 ml of the venous blood of the patients was collected, and the anti-HBs was detected by Chemiluminescent Microparticle Immunoassay (CMIA). On the basis of previous studies, this study focused on analyzing the immunogenicity and persistence of hepatitis B vaccine under different CD4 levels.Results:One month later after the whole course of hepatitis B vaccination, the anti-HBs geometric mean concentration (GMC), anti-HBs positive rate (≥10 mIU/ml) and strong positive rate (≥100 mIU/ml) in HIV patients with CD4 <350 cells/μl were 442.50 mIU/ml, 71.05% (27/38) and 44.74% (17/38), respectively, which were significantly lower than those HIV-infected patients with CD4 ≥350 cells/μl [583.90 mIU/ml, 92.13% (117/127) and 77.95% (99/127)] ( n P<0.05). After controlling the confounding factors, the probability of being anti-HBs positive induced by hepatitis B vaccine in patients with CD4 <350 cells/μl was 0.14 times higher than in those with CD4≥350 cells/μl (95%n CI: 0.03-0.62), and patients with CD4 <350 cells/μl had higher risk of no response. From 6 months to 3 years after the whole course of the vaccination, the anti-HBs GMC (195.00-27.55 mIU/ml n vs. 300.10-45.81 mIU/ml), the positive rate (56.67%-36.67% n vs. 78.57%- 51.58%) and the strong positive rate (33.33%-6.67% n vs.44.64%-15.79%) in patients with CD4 <350 cells/μl gradually declined, lower than the levels in those with CD4 ≥350 cells/μl.n Conclusions:HIV-infected patients with CD4 <350 cells/μl have high risk of no response to hepatitis B vaccination and poor immune persistence. It is necessary to strengthen the anti-HBs monitoring in HIV-infected patients, with special attention to those with CD4 <350 cells/μl. When anti-HBs is negative, hepatitis B vaccine should be injected as early as possible.
