Liver-related death in human immunodeficiency virus (HIV)-infected individuals is about 10 times higher compared with the general population, and the prevalence of significant liver fibrosis in those with HIV approaches 15%. The present study aimed to assess risk factors for development of hepatic fibrosis in HIV patients receiving a modern combination anti-retroviral therapy (cART). This cross-sectional prospective study included 432 HIV patients, of which 68 (16%) patients were anti-hepatitis C virus (HCV) positive and 23 (5%) were HBsAg positive. Health trajectory including clinical characteristics and liver fibrosis stage assessed by transient elastography were collected at inclusion. Liver stiffness values >7.1 kPa were considered as significant fibrosis, while values >12.5 kPa were defined as severe fibrosis. Logistic regression and Cox regression uni- and multivariate analyses were performed to identify independent factors associated with liver fibrosis. Significant liver fibrosis was detected in 10% of HIV mono-infected, in 37% of HCV co-infected patients, and in 18% of hepatitis B virus co-infected patients. The presence of diabetes mellitus (odds ratio [OR] = 4.6) and FIB4 score (OR = 2.4) were independently associated with presence of significant fibrosis in the whole cohort. Similarly, diabetes mellitus (OR = 5.4), adiposity (OR = 4.6), and the FIB4 score (OR = 3.3) were independently associated with significant fibrosis in HIV mono-infected patients. Importantly, cumulative cART duration protected, whereas persistent HIV viral replication promoted the development of significant liver fibrosis along the duration of HIV infection. Our findings strongly indicate that besides known risk factors like metabolic disorders, HIV may also have a direct effect on fibrogenesis. Successful cART leading to complete suppression of HIV replication might protect from development of liver fibrosis.
与普通人群相比,感染人类免疫缺陷病毒(HIV)的个体中与肝脏相关的死亡率高出约10倍,且HIV感染者中显著肝纤维化的患病率接近15%。本研究旨在评估接受现代联合抗逆转录病毒疗法(cART)的HIV患者发生肝纤维化的危险因素。这项横断面前瞻性研究纳入了432例HIV患者,其中68例(16%)抗丙型肝炎病毒(HCV)呈阳性,23例(5%)乙肝表面抗原(HBsAg)呈阳性。在纳入研究时收集了健康轨迹,包括临床特征以及通过瞬时弹性成像评估的肝纤维化阶段。肝脏硬度值>7.1 kPa被视为显著纤维化,而值>12.5 kPa被定义为严重纤维化。进行了逻辑回归和Cox回归单因素及多因素分析,以确定与肝纤维化相关的独立因素。在单纯HIV感染患者中,10%检测到显著肝纤维化;在HCV合并感染患者中,37%检测到显著肝纤维化;在乙肝病毒合并感染患者中,18%检测到显著肝纤维化。在整个队列中,糖尿病的存在(比值比[OR]=4.6)和FIB4评分(OR=2.4)与显著纤维化的存在独立相关。同样,在单纯HIV感染患者中,糖尿病(OR=5.4)、肥胖(OR=4.6)和FIB4评分(OR=3.3)与显著纤维化独立相关。重要的是,cART的累积持续时间具有保护作用,而持续性HIV病毒复制在HIV感染期间会促进显著肝纤维化的发展。我们的研究结果强烈表明,除了代谢紊乱等已知危险因素外,HIV可能也对纤维生成有直接影响。成功的cART导致HIV复制完全抑制可能会预防肝纤维化的发生。
