Abstract
AIM OF THE STUDY: Owing to the association between non-alcoholic fatty liver disease (NAFLD) and dyslipidemia, there is a need for new treatment strategies to manage both conditions concomitantly. Our aim in this study was to evaluate the effectiveness of pemafibrate in alleviating dyslipidemia-associated NAFLD, including the evaluation of its effects on liver function and body composition. MATERIAL AND METHODS: The study sample included 67 patients with dyslipidemia-associated NAFLD (29 males, mean age 65.7 years [range, 58.4-73.7]) who were administered pemafibrate continuously for a period of at least 12 months, between June 2019 and January 2022. Outcomes were the change in body composition indices (visceral adipose tissue index - VATI, subcutaneous adipose tissue index - SATI, and skeletal muscle index - SMI), lipid biochemistry, and liver function, reserve, and fibrosis score, from baseline to the 12-month time point of pemafibrate treatment. RESULTS: Pemafibrate treatment improved liver function (alanine aminotransferase, aspartate aminotransferase, g-glutamyl transpeptidase, and alkaline phosphatase), and lipid biochemistry (triglycerides and total cholesterol). Improvements in ferritin and hepatic reserve (Mac-2 binding protein, albumin-to-bilirubin score, and NAFLD fibrosis score) were also observed, as well as a decrease in SATI. CONCLUSIONS: Pemafibrate improved dyslipidemia, liver function, and hepatic reserve. The positive effects of pemafibrate on body composition likely contributed to the improvements in liver function. Longer-term treatment may be necessary to influence VATI and thus to further evaluate the relationship between improved body composition and NAFLD with pemafibrate treatment.
