İleri Evre Kronik Böbrek Hastalarında, Dipeptidl Peptidaz-4 İnhibitörlerinin Böbrek Fonksiyonu Üzerindeki Etkisi

Abstract

Objective: This study aimed to investigate the effects of DPP-4 inhibitors on kidney function in type 2 diabetes mellitus patients with stages 3-5 chronic kidney disease, focusing on estimated glomerular filtration rate and proteinuria. Methods: This is a retrospective case-control design, and data were collected from a single hospital's software and the Turkish Ministry of Health's National Data Tracking System. Diabetic patients with T2DM and CKD stages 3-5 were included, with dipeptidyl peptidase-4 inhibitor users (n=118) and non-users (n=48) forming the intervention and control groups, respectively. Baseline demographics, clinical characteristics, and outcomes were compared between groups. Results: At baseline, both groups demonstrated similar age, gender distribution, body mass index, and eGFR. Over a 12-month follow-up, while slight improvements in eGFR were observed in the intervention group and minor reductions in the control group, these changes did not reach statistical significance (p>0.05). Proteinuria showed a stable trend in the intervention group, whereas a significant increase was noted in the control group (p=0.035). Age significantly correlated with eGFR (p
