Recent Advances in Treating Nonalcoholic Steatohepatitis (NASH)
The complex pathophysiology of NASH and combination therapies targeting multiple pathways are gaining traction.
FREMONT, CA: Non-alcoholic steatohepatitis (NASH) represents a severe variant of non-alcoholic fatty liver disease (NAFLD), marked by liver inflammation and damage from fat accumulation. Its potential progression to cirrhosis and liver cancer has driven research into targeted therapies. Key pathways involved in NASH include insulin resistance, oxidative stress, inflammation, and fibrosis, aiding the identification of biomarkers for monitoring and early diagnosis.
Non-invasive biomarkers, such as circulating microRNAs, lipid metabolites, and specific proteins, are increasingly being used to predict disease progression and response to treatment, reducing the reliance on liver biopsies. Weight loss through bariatric surgery has shown promise in reversing NASH in obese patients. Pharmacotherapy is rapidly evolving, with several promising candidates in late-stage clinical trials. The approaches aim to enhance therapeutic efficacy and mitigate side effects. For instance, combining FXR agonists with GLP-1 receptor agonists may offer synergistic benefits by addressing metabolic dysfunction and liver inflammation.
