Non-Invasive Hepatic and Metabolic Index Changes After Incretin Therapy in Overweight/Obesity (GLP-NIT)
Early Changes in Non-Invasive Hepatic and Metabolic Indices After Incretin-Based Therapy in Patients With Overweight or Obesity: Real-World Evidence From a Turkish Cohort

Intervento / Trattamento
Descrizione dettagliata
Adults aged 18 years or older with overweight or obesity who were considered at increased metabolic risk for MASLD and who received continuous subcutaneous semaglutide or tirzepatide for at least 12 weeks were retrospectively identified at the internal medicine clinic of a tertiary-care state hospital in Istanbul, Turkey. Patients with significant alcohol consumption, other chronic liver disease etiologies, prior bariatric surgery, recent initiation/dose change of MASLD-relevant medications, concurrent hepatotoxic agent use, or missing baseline/follow-up data were excluded.
Baseline values were defined as the most recent measurements within 4 weeks before treatment initiation; follow-up values were the earliest measurements obtained after at least 12 continuous weeks of therapy. FIB-4, APRI, HSI, and TyG were calculated at both time points. Wilcoxon signed-rank tests compared baseline-to-follow-up changes. Kendall's tau assessed exploratory correlations among change scores; Spearman's rho assessed two prespecified correlations (percentage body-weight change vs. index changes; ΔHbA1c vs. index changes in the diabetic subgroup). Multivariable linear regression (enter method) identified independent predictors of ΔFIB-4, ΔAPRI, ΔHSI, and ΔTyG, adjusting for baseline index value, weight change, follow-up duration, baseline HbA1c, sex, and age.
Agent choice (semaglutide vs. tirzepatide) and dose titration were at the discretion of the treating physician; patients receiving either agent were analyzed together as a drug class, without dose-based stratification, since the study's aim was to characterize the class-level early index response rather than compare individual agents.
