FGF23 and diabetic kidney disease: These results seem to remain in agreement with earlier findings published in the same journal (Clinicaj Journal of the American Association of Nephrology) by Titan et al.—these authors found that FGF23 predicts the combined outcome defined as death, doubling of serum creatinine or a need for dialysis in the cohort of diabetic patients with microalbuminuria and reduced baseline eGFR (i.e., with established DKD) [81].
