Essential phospholipids and enzyme-based staging in nonalcoholic fatty liver disease: A call to action.

Nonalcoholic fatty liver disease, recently termed metabolic dysfunction-associated steatotic liver disease, affects 25% of adults globally, with a prevalence reaching 93% in obese individuals. The MANPOWER study, a post hoc analysis of 2843 Russian patients with newly diagnosed nonalcoholic fatty liver disease, evaluated Essentiale Forte N® [essential phospholipids (EPLs)] therapy and a liver enzyme-based staging algorithm. Using generalized linear regression and McNemar tests, EPLs reduced liver enzyme levels (alanine aminotransferase: -20.4 U/L, aspartate aminotransferase: -16.9 U/L, gamma-glutamyl transferase: -17.1 U/L at 24 weeks, P < 0.001) and improved ultrasonography findings (76.8% reduction in hyperechogenicity, P < 0.001). A logistic regression algorithm using alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase levels achieved 72.3% accuracy, 75.6% sensitivity, 71.0% specificity, and an area under the receiver operating characteristic curve of 0.74 (95% confidence interval: 0.71-0.77) for identifying nonalcoholic steatohepatitis. These findings advocate EPLs as a safe, effective therapy and propose a scalable diagnostic tool, urging validation to reduce the reliance on biopsy.
