An effective therapeutic strategy for HBV cure remains an urgent unmet need. We aimed to define the incidence, kinetics and predictors of hepatitis B surface antigen (HBsAg) loss in people living with HIV and HBV (PLWH-HBV) following HBV-active antiretroviral therapy (ART) in PLWH-HBV in Asia.
97 PLWH-HBV commencing HBV-active ART were recruited prospectively in Thailand (n=94) and Malaysia (n=3) then followed for 24 months. Time to HBV serology change was calculated. Univariate associations between baseline characteristics and HBsAg loss were examined using the Mann-Whitney or Chi-square tests. Multivariable analysis was undertaken using Cox regression.
21 individuals (22%) lost HBsAg during follow-up (11.7 per 100 PY), 14 of whom gained anti-HBs. 22/61 (36.1%) individuals who were hepatitis B "e" antigen (HBeAg) positive at baseline lost HBeAg over the study, 15 of whom gained anti-HBe. Most individuals lost HBsAg and HBeAg by the month 12 study visit (81% and 63.6%, respectively), with median times of 5.8 and 12.0 months to HBsAg and HBeAg loss, respectively. Univariate analysis showed baseline characteristics associated with HBsAg loss were higher alanine aminotransferase (ALT, p=0.005), tenofovir alafenamide (TAF)-containing ART regimen (p=0.025), younger age (p=0.040), lower liver stiffness (p=0.010) and quantitative HBsAg< log102.0 IU/ml (p=0.001). All 5 factors remained significant in a Cox regression analysis that adjusted for baseline CD4 count.
High HBsAg loss rates occur in people living with HIV and HBV early after commencing ART. Our study suggests that TAF-containing ART regimens may be preferable as first line therapy in HIV-HBV co-infection.
有效的乙肝治愈治疗策略仍是亟待满足的需求。我们旨在确定亚洲地区接受乙肝活性抗逆转录病毒治疗(ART)的艾滋病毒和乙肝病毒合并感染者(PLWH-HBV)中乙肝表面抗原(HBsAg)消失的发生率、动力学及预测因素。
前瞻性招募了97例开始接受乙肝活性ART的PLWH-HBV患者,其中泰国94例,马来西亚3例,随后进行24个月的随访。计算乙肝血清学变化的时间。使用Mann-Whitney检验或卡方检验分析基线特征与HBsAg消失之间的单变量关联。采用Cox回归进行多变量分析。
21例患者(22%)在随访期间HBsAg消失(每100人年11.7例),其中14例产生了抗-HBs。基线时乙肝e抗原(HBeAg)阳性的22/61例患者(36.1%)在研究期间HBeAg消失,其中15例产生了抗-HBe。大多数患者在第12个月的研究访视时HBsAg和HBeAg消失(分别为81%和63.6%),HBsAg和HBeAg消失的中位时间分别为5.8个月和12.0个月。单变量分析显示,与HBsAg消失相关的基线特征包括较高的丙氨酸氨基转移酶(ALT,p=0.005)、含替诺福韦艾拉酚胺(TAF)的ART方案(p=0.025)、较年轻的年龄(p=0.040)、较低的肝脏硬度(p=0.010)以及定量HBsAg<log102.0 IU/ml(p=0.001)。在对基线CD4细胞计数进行校正的Cox回归分析中,所有这5个因素仍然具有显著性。
艾滋病毒和乙肝病毒合并感染者在开始ART后早期HBsAg消失率较高。我们的研究表明,含TAF的ART方案可能更适合作为艾滋病毒-乙肝病毒合并感染的一线治疗方案。
