鉴于低肌肉质量可能导致慢性感染患者的健康状况恶化,我们评估了美国成年人慢性丙型肝炎病毒感染是否与低肌肉质量相关。我们对全国健康检查和营养研究(1999-2010)进行了横断面研究。慢性HCV感染患者可检测到HCV RNA。低肌肉质量定义为中上臂周长 (MUAC) <第 10 个百分位数。使用多变量逻辑回归来确定与慢性 HCV 相关的低肌肉质量的调整优势比 (aOR) 和 95% 置信区间 (CI)。在 18,513 名成人中,慢性 HCV 感染者 (n=303) 的低肌肉质量患病率高于未感染者(13.8% vs 6.7%;aOR,2.22;95% CI,1.39-3.56),并且在无明显肝纤维化的人群中重复分析时,这种关联仍然存在(aOR,2.12;95% CI, 1.30-3.47)。这项研究表明,通过 MUAC 测量评估,即使没有晚期肝病,慢性 HCV 感染也与低肌肉质量相关。
Given that low muscle mass can lead to worse health outcomes in patients with chronic infections, we assessed if chronic HCV infection was associated with low muscle mass among U.S. adults. We performed a cross-sectional study of the National Health Examination and Nutrition Study (1999-2010). Chronic HCV-infected patients had detectable HCV RNA. Low muscle mass was defined as <10th percentile for mid-upper arm circumference (MUAC). Multivariable logistic regression was used to determine adjusted odds ratios (aORs) with 95% confidence intervals (CIs) of low muscle mass associated with chronic HCV. Among 18,513 adults, chronic HCV-infected patients (n=303) had a higher prevalence of low muscle mass than uninfected persons (13.8% versus 6.7%; aOR, 2.22; 95% CI, 1.39-3.56), and this association remained when analyses were repeated among persons without significant liver fibrosis (aOR, 2.12; 95% CI, 1.30-3.47). This study demonstrates that chronic HCV infection is associated with low muscle mass, as assessed by MUAC measurements, even in the absence of advanced liver disease.
