Perilipin-2 (PLIN2), the most abundant lipid droplet protein in the liver, is linked to lipid accumulation and inflammation, the hallmarks of NAFLD. The role of PLIN2 in NAFLD etiopathogenesis remains partially understood. This study aims to elucidate the relationship between serum PLIN2 levels and other disease-related parameters in NAFLD, investigate the role of PLIN2 in disease pathogenesis, and evaluate its utility as a biomarker in NAFLD diagnosis. Methods: The study included 46 patients diagnosed with NAFLD who presented internal medicine outpatient clinics and 44 healthy controls. Results: Serum PLIN2 level was found to be statistically significantly higher in the NAFLD patient group compared to the control group. In the NAFLD group, a statistically significant positive correlation was detected between PLIN2 and Body Mass Index (BMI), hip circumference, C-reactive protein (CRP), and platelet count. In ROC analysis, taking the cut-off value for serum PLIN2 level as 5.52 ng/mL predicted the diagnosis of NAFLD with 50% sensitivity and 97.7% specificity. Conclusions: PLIN2 determination demonstrated high specificity at the proposed cut-off value and may represent a promising complementary biomarker for NAFLD, particularly when interpreted alongside other clinical and laboratory parameters. Circulating PLIN2 appears to be influenced by metabolic and inflammatory parameters.  \nKeywords: hepatic steatosis index; inflammation; non-alcoholic fatty liver disease; perilipin-2  \n1. Introduction  \nNon-alcoholic fatty liver disease (NAFLD), also referred to as metabolic dysfunctionassociated fatty liver disease (MAFLD), is a metabolic disorder characterized by the accumulation of more than 5% fat in hepatocytes, closely associated with other metabolic abnormalities such as Type 2 Diabetes Mellitus (T2D), obesity, hypercholesterolemia, and insulin resistance (IR) [1] . To resolve issues associated with the former NAFLD nomenclature, APASL pioneered the adoption of the MAFLD definition, shifting the diagnostic focus  \nto the presence of metabolic dysfunction ","cbCaijV00DExvxeV","https://ap.wps.com/l/cbCaijV00DExvxeV","pdf",968856,15,"English","# Abstract\n# Introduction\n## Background on NAFLD and MAFLD\n## Imaging and diagnostic approaches\n## Lipid droplets and PLIN2 biology","[{\"question\":\"What is the purpose of measuring serum PLIN2 in NAFLD?\",\"answer\":\"To clarify the relationship between serum PLIN2 levels and other NAFLD-related parameters, assess PLIN2’s role in disease pathogenesis, and evaluate its usefulness as a biomarker for NAFLD diagnosis.\"},{\"question\":\"How does serum PLIN2 differ between NAFLD patients and healthy controls?\",\"answer\":\"Serum PLIN2 levels are statistically significantly higher in the NAFLD patient group than in the control group.\"},{\"question\":\"What diagnostic performance did PLIN2 show in ROC analysis?\",\"answer\":\"Using a proposed cut-off of 5.52 ng/mL, PLIN2 predicted NAFLD with 50% sensitivity and 97.7% specificity.\"}]","The Importance of Serum Perilipin-2 Level as an Early Indicator of Inflammation in Non-Alcoholic Fatty Liver Disease | PDF",1790769767,38]
