Abstract
Nonalcoholic steatohepatitis (NASH) is a progressive form of nonalcoholic fatty liver disease (NAFLD) associated with metabolic syndrome and increased cardiovascular risk. Resmetirom, a novel liver-directed selective thyroid hormone receptor-β (THR-β) agonist, has shown promise in addressing both hepatic and systemic lipid metabolism. This systematic review and meta-analysis aimed to evaluate the efficacy of resmetirom in improving cholesterol levels in NASH patients. A systematic literature search was conducted across multiple databases including PubMed, Embase, Cochrane Library, andClinicalTrials.gov, identifying three randomized controlled trials for inclusion. The meta-analysis revealed that resmetirom significantly reduced low-density lipoprotein cholesterol (LDL-C) levels compared to placebo (MD: -23.62; 95% CI: -37.32 to -9.93; p < 0.001). Similarly, triglyceride (TG) levels showed a significant reduction in the resmetirom group (MD: -33.86; 95% CI: -47.79 to -19.92; p < 0.001). Importantly, there was no significant difference in the risk of serious adverse events between resmetirom and placebo groups (RR: 1.09; 95% CI: 0.73 to 1.63; p = 0.67). These findings suggest that resmetirom effectively improves lipid profiles in NASH patients without compromising safety. However, the analysis was limited by the small number of studies, all from the same research group, and high heterogeneity in results. Future research should include more diverse studies, longer follow-up periods, and cost-effectiveness evaluations. Despite these limitations, resmetirom shows promise as a potential treatment for managing dyslipidemia and cardiovascular risk in NASH patients, potentially influencing future treatment guidelines for both liver and cardiovascular health in this population.
