摘要
Fatty liver has been present in the lives of patients and physicians for almost two centuries.Vast knowledge has been generated regarding its etiology and consequences,although a long path seeking novel and innovative diagnostic biomarkers for nonalcoholic fatty liver disease(NAFLD)and nonalcoholic steatohepatitis(NASH)is still envisioned.On the one hand,proteomics and lipidomics have emerged as potential noninvasive resources for NAFLD diagnosis.In contrast,metabolomics has been able to distinguish between NAFLD and NASH,even detecting degrees of fibrosis.On the other hand,genetic and epigenetic markers have been useful in monitoring disease progression,eventually functioning as target therapies.Other markers involved in immune dysregulation,oxidative stress,and inflammation are involved in the instauration and evolution of the disease.Finally,the fascinating gut microbiome is significantly involved in NAFLD and NASH.This review presents state-of-the-art biomarkers related to NAFLD and NASH and new promises that could eventually be positioned as diagnostic resources for this disease.As is evident,despite great advances in studying these biomarkers,there is still a long path before they translate into clinical benefits.
