Pemafibrate decreases markers of hepatic inflammation in patients with non-alcoholic fatty liver disease

AIM OF THE STUDY: Non-alcoholic fatty liver disease (NAFLD) is frequently complicated by dyslipidemia and is considered to be a hepatic manifestation of metabolic syndrome. Pemafibrate is a novel selective peroxisome proliferator-activated receptor-α modulator. There are no reports of the clinical effects of pemafibrate in patients with NAFLD. The aim of this study is to determine the effect of pemafibrate on patients with NAFLD. MATERIAL AND METHODS: This is an observational study of patients with NAFLD complicated by dyslipidemia treated with pemafibrate for three months. Patient medical records were retrospectively reviewed. RESULTS: Thirty-eight patients were included, and all patients had dyslipidemia without diabetes. Changes in parameters after three months of pemafibrate therapy were evaluated. Weight was not significantly changed. Alanine aminotransferase, a marker of hepatic inflammation, significantly improved. Remarkably, alkaline phosphatase and γ-glutamyl transpeptidase decreased in all patients. The albumin-bilirubin score, a marker of hepatic function, improved due to significant elevation of serum albumin and decrease in total bilirubin. Lipid profiles including high-density lipoprotein cholesterol and triglycerides significantly decreased. Low-density lipoprotein cholesterol did not significantly change. The NAFLD fibrosis score significantly improved, but the FIB-4 index did not significantly change. CONCLUSIONS: Three months of pemafibrate treatment of patients with NAFLD improves markers of hepatic inflammation, function and fibrosis. This is the first clinical study evaluating the effect of pemafibrate in patients with NAFLD.
