摘要
目的分析HIV感染者接种乙型肝炎(简称乙肝)疫苗后5年血清乙肝表面抗体(抗-HBs)阳性率及其影响因素,为优化HIV感染者乙肝疫苗免疫策略提供科学依据。方法以云南省德宏州HBV五项检测均为阴性并完成5年随访的761例HIV感染者为研究对象。在首针接种后5年时检测抗-HBs,分析HIV感染者乙肝疫苗接种后的长期免疫效果及其影响因素。结果761例HIV感染者中359例(47.2%)完成乙肝疫苗接种。5年抗体阳性率为12.2%(93/761),接种组为21.2%(76/359),未接种组为4.2%(17/402);多因素分析结果显示,接种乙肝疫苗、女性感染者5年血清抗-HBs阳性率较高,较大年龄、病毒载量≥200 copies/mL则较低。进一步对接种疫苗的359例HIV感染者进行多因素分析,结果显示,女性感染者(OR=2.38,95%CI:1.29~4.39)在接种乙肝疫苗5年后血清抗-HBs阳性率水平显著高于男性感染者;而较大年龄(40~49岁:OR=0.38,95%CI:0.17~0.85;≥50岁:OR=0.21,95%CI:0.07~0.65)的感染者则显著低于15~29岁的感染者。结论HIV感染者注射乙肝疫苗5年后抗-HBs水平仍显著高于未接种者,但男性、大龄及病毒载量较高者接种后免疫持久性较差,应予以关注。
Objective To investigate the prevalence and associated factors of serum hepatitis B surface antibody(anti-HBs)and 5 years after completion of first hepatitis B vaccination among HIV-infected persons.Methods A total of 761 HIV-infected persons in Dehong prefecture of Yunnan province who were both negative for hepatitis B and completed 5-year follow-up were included.Anti-HBs was measured 5 years after the first vaccination.Results Hepatitis B vaccination was completed in 359(47.2%)of 761 HIV-infected patients.The 5-year prevalence of anti-HBs was 12.2%(93/761),with a prevalence of 21.2%(76/359)and 4.2%(17/402)in the vaccinated and unvaccinated group respectively.Multivariate analysis showed that serum anti-HBs among all participants was higher in women infected with hepatitis B vaccine for 5 years,but lower in people with older age and viral load≥200 copies/mL.Multivariate analysis of 359 HIVinfected persons who were vaccinated,the female(OR=2.38,95%CI:1.29-4.39)were associated with increased serum anti-HBs prevalence.The older age(40~49 years:OR=0.38,95%CI:0.17-0.85;≥50 years:OR=0.21,95%CI:0.07-0.65)were associated with reduced serum anti-HBs prevalence.Conclusions Seroprevalence of anti-HBs antibody among HIV-infected persons after 5 years of HBV vaccination is still significantly higher than those unvaccinated.However,the sustainability of anti-HBs antibody is relatively lower among vaccinated HIVinfected persons who are male and older with higher viral load,which calls for particular attentions.
