Background: Type 2 diabetes mellitus (DM) is the most common cause of end- stage renal disease. Albuminuria is the foremost commonly utilized marker to anticipate onset of diabetic nephropathy (DN) without sufficient affectability and specificity to identify early DN.
Aim: This study aimed to evaluate plasma α-Klotho as a new biomarker for early DN.
Methods: This cross sectional study included 125 Egyptian subjects attending the out Patients Clinic of the Department of Internal Medicine, 10Th of Ramadan city Health Insurance Hospital and divided into:-control group, patient with diabetic mellitus, patients with Diabetic nephropathy and patient with diabetic nephropathy and other complications. Patients were subjected to measurement of plasma α- Klotho, FBS, HbAIC, serum Creatinine, serum urea, serum uric acid, k, Na, serum phosphorus, Albumin: Creatinine Ratio, GFR, Chol, TG, LDL HDL, AST, ALT, T.BIL, D.BIL ALB, TP, GLB and A/G ratio.
Results: Results showed that plasma a-klotho was significantly correlated with haemoglobin A1C, potassium, GFR, Albumin, TP and GLB. Meanwhile, plasma α - klotho was negatively correlated with duration of DM, CR, Urea, UR.A, Na, phosphorus, ACR, Chol, TG, LDL, AST, ALT, T.BIL, and D.BIL. However, there were no significant correlations between plasma a-klotho and FBS, HDL and A/G ratio. At cut-off level ≥2.6, plasma a-klotho had 95% sensitivity and 81% specificity for diagnosing diabetic nephropathy.
Conclusion: α-klotho may be the early markers for predict in renal injury in patients with type 2 diabetes.
