BACKGROUND &AIMS We aimed to describe the incidence of liver related events (LRE) in a population of hepatitis C compensated advanced chronic liver disease (cACLD) patients who achieved sustained virological response (SVR) after direct-acting antiviral (DAA) therapy and identify non-invasive parameters to predict the occurrence of LRE. METHODS This two-center prospective study included 572 cACLD patients who had been treated with DAA and had achieved SVR. Patients had liver stiffness measurement (LSM) ≥10 kPa at baseline and had never decompensated (Child Pugh class A). Laboratory work up and LSM was performed at baseline and at one year of follow up (FU). RESULTS The median follow-up was 2.8 years during which 32 patients (5.6%) presented LRE. The incidence rate (IR) of portal hypertension related decompensation was 0.34/100 patient-years. These patients had all baseline LSM>20 kPa and in 4 out of 5 LSM did not improve during FU. HCC occurred in 25 patients (IR 1.5/100 patient-years). Albumin levels at FU (HR 0.08, 95% CI: 0.02-0.25) and LSM <10 kPa at FU (HR 0.33, 95% CI: 0.11-0.96) were independently associated with the risk of HCC. Combining both predictors we identified two different risk groups of HCC occurrence, being those with LSM ≥20 kPa at FU and with LSM between 10-20 kPa and albumin levels <4.4 g/dL the ones with the highest risk (IR ≥1.9/100 patient-years). Visual nomograms predicting HCC risk during time based on LSM and albumin at one year of FU were constructed. CONCLUSION In hepatitis C cACLD patients who have achieved SVR with DAA, HCC is the most frequent LRE. Both albumin levels and LSM during FU are useful to stratify the risk of presenting HCC. LAY SUMMARY The new oral antivirals can cure chronic hepatitis C infection, however patients with advanced chronic liver disease are still at risk of presenting complications. The most frequent complication after oral antivirals therapy in asymptomatic patients with advanced chronic liver disease was liver cancer. The use of simple parameters such liver stiffness and albumin levels after treatment can help to identify patients with different risks of presenting liver cancer.

HCV代偿性晚期慢性肝病患者口服抗病毒药物后肝脏相关事件的无创预测

背景和目的 我们旨在描述在直接作用抗病毒 (DAA) 治疗后获得持续病毒学应答 (SVR) 的丙型肝炎代偿晚期慢性肝病 (cACLD) 患者人群中肝脏相关事件 (LRE) 的发生率,并确定非- 侵入性参数来预测 LRE 的发生。方法 这项两中心前瞻性研究包括 572 名接受 DAA 治疗并获得 SVR 的 cACLD 患者。患者基线时肝脏硬度测量值 (LSM) ≥ 10 kPa 且从未失代偿(Child Pugh A 级)。在基线和一年随访 (FU) 时进行实验室检查和 LSM。结果 中位随访时间为 2.8 年,其中 32 名患者 (5.6%) 出现 LRE。门静脉高压相关失代偿的发生率为 0.34/100 患者年。这些患者的所有基线 LSM > 20 kPa,并且 5 名 LSM 中有 4 名在 FU 期间没有改善。25 名患者发生 HCC(IR 1.5/100 患者年)。FU 时的白蛋白水平(HR 0.08,95% CI:0.02-0.25)和 FU 时 LSM <10 kPa(HR 0.33,95% CI:0.11-0.96)与 HCC 风险独立相关。结合这两个预测因素,我们确定了 HCC 发生的两个不同风险组,即 FU 时 LSM ≥20 kPa 和 LSM 介于 10-20 kPa 和白蛋白水平 <4.4 g/dL 的那些风险最高 (IR ≥1.9/100患者年)。构建了基于 FU 一年时的 LSM 和白蛋白预测 HCC 风险的视觉列线图。结论 在使用 DAA 实现 SVR 的丙型肝炎 cACLD 患者中,HCC 是最常见的 LRE。FU 期间的白蛋白水平和 LSM 都有助于对呈现 HCC 的风险进行分层。概述 新型口服抗病毒药物可治愈慢性丙型肝炎感染,但晚期慢性肝病患者仍有出现并发症的风险。晚期慢性肝病无症状患者口服抗病毒药物治疗后最常见的并发症是肝癌。使用简单的参数,例如治疗后的肝脏硬度和白蛋白水平,可以帮助识别具有不同风险的肝癌患者。
