Nonalcoholic steatohepatitis (NASH) is one of the most common liver diseases that is diagnosed by biopsy and, therefore, requires the development of non-invasive tests for diagnosis. Serum levels of microRNAs were shown to correlate with the severity of various liver diseases, but the role of miR-378a and miR-181b-5p in NASH remains unclear. The current study aims to assess the serum expression level of miR-378a-3p and miR-181b-5p in patients with NASH and to find out the correlation of these indices with liver fibrosis. The case-control research was carried out on 60 patients with confirmed NASH relative to 50 healthy subjects. Extraction and reverse transcription of micro RNAs was performed using miRCURY LNA RT Kit (Qiagen, Maryland, USA) Detection of miR-378a-3p and miR-181b-5p was done using qPCR. It was shown that serum expression level of miR-378a-3p in NASH patients was downregulated with a median range fold change 0.29, while that of miR-181b-5p was upregulated with a median range fold change 13.08. The ROC curve was constructed to discriminate the NASH group from the healthy group. The optimal cut-off value of miR-378a-3p was ≤0.031 with a sensitivity of 65%, the optimal cut-off value of miR-181b-5p was ≥ 0.063 with a sensitivity of 93.3%. Statistically significant positive correlation between miR-181b-5p level and fibroscan data was demonstrated. The present study showed that serum miR-378a-3p and miR-181b-5p could be used as biomarkers of NASH.

Non-alcoholic fatty liver disease occurs in most obese people, the main pathway of which is the process of fibrogenesis. The aim of this work was to determine the potential biomarkers for early diagnosis of liver fibrogenesis in adolescents with obesity. The levels of liver fibrosis markers, such as fibronectin, collagen type IV, N-terminal propeptides and C-terminal telopeptides of type I collagen, were assessed with the use of IFA method in serum of 226 patients with obesity aged 8-18 years. A significant increase in levels of type IV collagen and fibronectin was observed in children with obesity (P < 0.05). As diagnostic criteria for fibrogenesis and fibrolysis, the levels of N-terminal propeptides and C-terminal telopeptides of type I collagen, respectively, were determined. The serum level of N-terminal propeptides of type I collagen significantly exceeds the normal values in all children with obesity compared to the control group (P < 0.05). The biochemical markers (type IV collagen, fibronectin, N-terminal propeptides and C-terminal telopeptides of type I collagen) were proven to have high diagnostic informative value in the early diagnosis of liver fibrogenesis in obese adolescents. It was shown that the signs of fibrosis in non-alcoholic fatty liver disease already occur at the stage of steatosis.
