Abstract. Objective: to study relationship of selectins with features of course of non-alcoholic fatty liver disease (NAFLD).
Material and methods. 208 patients with NAFLD (107 men, 101 women) aged from 18 to 65 years were included in study. In 64,4% of cases disease was characterized by absence of increase in activity of cytolytic enzymes, in 35,6% of patients there was variant with increase in activity of alanine (AlAT) and aspartic (AsAT) aminotransferases. Patients were more likely to have mild (40,8%) and moderate (38,5%) hepatic steatosis. The metabolic syndrome was detected in 59,1% of NAFLD cases.
Results. Statistically significant increase of levels of E-, P- and L-selectins in blood was present in NAFLD. In patients with increased activity of aminotransferases concentration of E-selectin in blood was higher than in those with normal levels of AsAT and AlAT. The comorbidity of NAFLD and metabolic syndrome was characterized by decrease in levels of L-selectin in blood. With increasing severity of liver steatosis levels of E-selectin in blood increased, and levels of L-selectin decreased, reaching extreme values in steatosis of 3rd degree. The threshold values of E-selectin ≥51 ng/ml had moderate accuracy (74,6%) in distinguishing between the norm and NAFLD.
Conclusion. Increased levels of selectins in blood is interrelated with variants of course of NAFLD. Association of selectins imbalance with severity of disease indicates clinical and pathogenetic significance of endothelial mediators in non-alcoholic fatty liver disease.
