Nonalcoholic Steatohepatitis Therapeutics and Diagnostics: Advancing Care for a Chronic Liver Condition
Nonalcoholic steatohepatitis (NASH) is a serious liver disease characterized by fat accumulation, inflammation, and progressive liver damage unrelated to alcohol use. It is part of the nonalcoholic fatty liver disease (NAFLD) spectrum and can advance to fibrosis, cirrhosis, or liver cancer.
Therapeutics and diagnostics for NASH are rapidly evolving as awareness grows about its long-term complications.
Diagnostics include imaging tests such as ultrasound elastography, MRI-based fat quantification, and FibroScan to assess liver stiffness. Blood biomarkers and liver function panels also support diagnosis, though biopsy remains the gold standard for confirming inflammation and fibrosis. Early diagnosis is critical, as many patients remain asymptomatic until advanced disease develops.
Therapeutic options focus on reducing liver fat, controlling inflammation, and preventing fibrosis progression. Lifestyle modifications—diet, weight management, exercise—remain the cornerstone of treatment. Pharmacological research targets metabolic pathways, insulin resistance, oxidative stress, and inflammatory mediators. Emerging therapies include FXR agonists, PPAR modulators, GLP-1 analogs, and…
