Our study aimed to determine the association between serum OGN and impaired kidney function risk in T2D patients and to analyze its potential role as an estimator of kidney disturbances in this population. This cross-sectional study included 147 T2D patients (65 ± 8 years, 58.5% males), and 75 healthy controls (63 ± 10 years, 36% males). Circulating OGN levels were determined by ELISA. Linear regression modeling was performed to determine the variables influencing circulating OGN, and an ROC curve was plotted to assess the usefulness of OGN as an estimator of diabetic kidney disease risk. Circulating OGN was significantly increased in T2D patients compared to controls (18.41 (14.45-23.27) ng/mL vs. 8.74 (7.03-12.35) ng/mL; penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/biomarkerdiabetic kidney diseasekidney function impairmentosteoglycintype 2 diabetesresearch article34065223open access10.3390/jcm10102209PMC8161135https://www.mdpi.com/2077-0383/10/10/2209/pdf?version=1621493026https://pmc.ncbi.nlm.nih.gov/articles/PMC8161135/pdf
