Platelet‐associated biomarkers in nonalcoholic steatohepatitis: Insights from a female cohort with obesity

Abstract

BackgroundThere is a lack of noninvasive diagnostic methods for nonalcoholic steatohepatitis (NASH), the severe condition of metabolic dysfunction‐associated steatotic liver disease (MASLD). Platelet activation, evaluated through certain related parameters, is associated with liver disease and inflammation, but previous results are inconclusive.AimTo investigate the potential utility of platelet‐related indices as noninvasive diagnostic markers for the detection and prediction of MASLD, focusing on NASH.ResultsWe found that mean platelet volume (MPV), plateletcrit (PCT) and platelet distribution width (PDW) were increased in the severe and morbidly obese (SMO) group compared to the normal weight (NW) group. We found decreased levels of MPV in steatosis and NASH patients. MPV and PCT values were decreased in the presence of mild liver inflammation. Platelet count (PLA) and PCT values were lower in the presence of ballooning. We obtained an area under the ROC curve of 0.84 using MPV and three other variables to predict MASLD.ConclusionsSome platelet‐related indices vary depending on liver condition. Here, we reported decreased MPV in MASLD presence. Moreover, we presented for the first time a predictive model using MPV, ALT levels and the presence of diabetes mellitus and metabolic syndrome to predict MASLD in obese women. Also, MPV is closely related to early liver inflammation in NASH, and PLA and PCT are related to hepatic ballooning. These indices could be widely used for the early detection of NASH since they are usually determined in routine laboratory tests.

Platelet, Antiplatelet Therapy and Metabolic Dysfunction-Associated Steatotic Liver Disease: A Narrative Review

“…In a recent work, MPV has been shown to be lower in women with MASLD associated with obesity and strictly correlated with early liver inflammatory response in NASH [98]. Specifically, platelet count and plateletcrit have been related to hepatic ballooning [98].…”
