As the global prevalence of chronic liver disease continues to rise, the need to determine which patients will develop end-stage liver disease and require liver transplantation is increasingly important. However, current prognostic models perform sub-optimally. We aim to determine microRNA profiles associated with clinical decompensation and mortality/transplantation within 1 year. We examined microRNA expression profiles in plasma samples from patients across the spectrum of cirrhosis (n = 154), acute liver failure (ALF) (n = 22), sepsis (n = 20) and healthy controls (HC) (n = 20). We demonstrated that a microRNA-based model (miR-24 and -27a) associated with systemic inflammation differentiated decompensated cirrhosis states from compensated cirrhosis and HC (AUC 0.77 (95% CI 0.69-0.85)). 6 patients within the compensated cirrhosis group decompensated the subsequent year and their exclusion improved model performance (AUC 0.81 (95% CI 0.71-0.89)). miR-191 (associated with liver injury) predicted risk of mortality across the cohort when acutely decompensated and acute-on-chronic-liver failure patients were included. When they were excluded miR-24 (associated with systemic inflammation) predicted risk of mortality. Our findings demonstrate that microRNA associated with systemic inflammation and liver injury predict adverse outcomes in cirrhosis. miR-24 and -191 require further investigation as prognostic biomarkers and therapeutic targets for patients with liver disease.
随着全球慢性肝病的患病率持续上升,确定哪些患者将发展为终末期肝病并需要进行肝移植变得越来越重要。然而,目前的预后模型表现并不理想。我们旨在确定与 1 年内临床失代偿和死亡/移植相关的 microRNA 谱。我们检测了来自肝硬化(n=154)、急性肝衰竭(ALF)(n=22)、脓毒症(n=20)和健康对照(HC)(n=20)患者的血浆样本中的 microRNA 表达谱。我们证明,与全身炎症相关的基于 microRNA 的模型(miR-24 和 -27a)可将失代偿性肝硬化状态与代偿性肝硬化和 HC 区分开来(AUC 0.77(95%CI 0.69-0.85))。在代偿性肝硬化组中,有 6 名患者在随后的一年中失代偿,排除他们后改善了模型性能(AUC 0.81(95%CI 0.71-0.89))。当急性失代偿和急性慢性肝衰竭患者被纳入时,miR-191(与肝损伤相关)预测了整个队列的死亡风险。当排除他们时,miR-24(与全身炎症相关)预测了死亡风险。我们的研究结果表明,与全身炎症和肝损伤相关的 microRNA 可预测肝硬化患者的不良结局。miR-24 和 -191 需要进一步研究,作为肝病患者的预后生物标志物和治疗靶点。
