MANF levels were quantified using enzyme-linked immunosorbent assays (ELISA), while urinary biomarkers and HbA1C were measured using standard clinical methods. Correlation analyses and multivariate regression models were employed to assess relationships between MANF and biomarkers.Results: MANF levels demonstrated a significant upward trend across albuminuria categories, with the highest levels observed in the macroalbuminuria group (514.5±112.3 pg/mL, p KW - Kidney Diseases KW - Chronic KW - Diabetic Nephropaties KW - Biological Markers KW - Blood Glucose KW - Neurotrophic Factors N2 - Objective: This study investigates the potential role of Mesencephalic Astrocyte-Derived Neurotrophic Factor (MANF) as a novel biomarker, evaluating its associations with established urinary biomarkers and glycemic control indicators in diabetes mellitus and diabetic nephropathy (DN).Methods: A cross-sectional study was conducted involving 84 participants stratified by albuminuria levels into normoalbuminuria, microalbuminuria, and macroalbuminuria groups.
