Understanding the comparative efficacy of empagliflozin and dapagliflozin in modulating hepatic and metabolic markers could guide therapeutic strategies in patients with type 2 diabetes mellitus (T2DM).Methods: This study included patients with T2DM who were initiated on empagliflozin or dapagliflozin and followed for 12 months. Clinical and laboratory parameters were assessed at baseline and 12 months, including weight, HbA1c, lipid profile, ALT, AST, and FIB-4 score. Propensity score matching was employed to identify responders (≥20% reduction in FIB-4) and non-responders. Receiver operating characteristic (ROC) analysis was performed to evaluate predictive markers for FIB-4 improvement.Results: A total of 200 patients were analyzed. Both empagliflozin and dapagliflozin groups demonstrated significant reductions in BMI, FBG, HbA1c, and FIB-4 scores (p < 0.001 for all). Between-group comparisons revealed no statistically significant differences in ΔBMI, ΔHbA1c, ΔAST, or ΔFIB-4. Among responders, the baseline FIB-4 score was significantly lower (1.48±0.52 vs. 1.80±0.42; p = 0.0445). ROC analysis identified ΔAST ≥7 U/L as the strongest predictor of FIB-4 response (AUC = 0.875, sensitivity = 83%, specificity = 83%).Conclusion: Both SGLT2 inhibitors significantly improved metabolic and hepatic parameters in patients with T2DM. The magnitude of AST reduction emerged as a robust predictor of FIB-4 improvement, underscoring its potential role in monitoring hepatic response to treatment. KW - SGLT2 inhibitors KW - empagliflozin KW - dapagliflozin KW - FIB-4 score KW - liver fibrosis KW - diabetes mellitus N2 - ÖzetGiriş: Sodyum-glukoz kotransportör 2 (SGLT2) inhibitörlerinin metabolik parametreler üzerinde olumlu etkileri gösterilmiştir; ancak Fibrosis-4 (FIB-4) skoru gibi karaciğer fibrozis indeksleri üzerindeki etkileri henüz yeterince araştırılmamıştır. Empagliflozin ve dapagliflozinin hepatik ve metabolik belirteçler üzerindeki karşılaştırmalı etkinliğinin anlaşılması, tip 2 diyabet mellitus (T2DM) hastalarında tedavi stratejilerine yön verebilir.Yöntemler: Bu çalışmaya empagliflozin veya dapagliflozin tedavisine başlanan T2DM hastaları dahil edildi ve 12 ay boyunca takip edildi. Başlangıçta ve 12. ayda; kilo, HbA1c, lipid profili, ALT, AST ve FIB-4 skoru dahil olmak üzere klinik ve laboratuvar parametreler değerlendirildi. FIB-4 skorunda ≥%20 azalma gösterenler “yanıtlayan”, göstermeyenler “yanıtlamayan” olarak kabul edilerek eğilim skoru eşleştirmesi (propensity score matching) uygulandı. FIB-4 iyileşmesini öngören belirteçleri değerlendirmek amacıyla ROC (receiver operating characteristic) analizi yapıldı.Bulgular: Toplam 200 hasta analiz edildi. Hem empagliflozin hem de dapagliflozin gruplarında BKİ, açlık kan şekeri, HbA1c ve FIB-4 skorlarında anlamlı düşüşler gözlendi (tümünde p < 0.001). Gruplar arası karşılaştırmalarda ΔBKİ, ΔHbA1c, ΔAST ve ΔFIB-4 açısından istatistiksel olarak anlamlı fark saptanmadı. Yanıtlayan hastalarda başlangıç FIB-4 skoru anlamlı şekilde daha düşüktü (1.48±0.52 vs. 1.80±0.42; p = 0.0445). ROC analizinde, FIB-4 yanıtının en güçlü belirleyicisi olarak ΔAST ≥7 U/L bulundu (EAA = 0.875, duyarlılık = %83, özgüllük = %83).Sonuç: Her iki SGLT2 inhibitörü de T2DM hastalarında metabolik ve hepatik parametrelerde anlamlı iyileşmeler sağlamıştır. AST düzeyindeki azalmanın büyüklüğü, FIB-4 skorundaki iyileşmenin güçlü bir belirleyicisi olarak öne çıkmakta ve tedaviye karaciğerin verdiği yanıtın izlenmesinde potansiyel bir rol taşıdığı görülmektedir.
