摘要：Backround: Elabela (ELA) is a hormone that is secreted at high levels in the kidneys of a healthy adult. This study aims to investigate whether serum ELA levels of patients with Type 2 Diabetes vary with the severity of renal damage. Methods: Our study included 50 healthy control subjects and 100 diabetic patients, who were categorized into groups based on urine albumin/creatinine ratios (ACR). Patients included in the study were assigned to four groups: Group 1 (healthy control), Group 2 (ACR300 mg/g normal or high serum creatinine). Physical examination findings, demographic characteristics of the study group were recorded, and serum ELA levels and other laboratory parameters were assessed using appropriate methods. Results: The results of the study indicated that ELA levels determined in healthy individuals gradually decreased through stages of normal albuminuria, microalbuminuria, and macroalbuminuria. Moreover, ELA had a significant negative corre- lation with LDL-C (r=-0.201, p=0.014), glucose (r=-0.437, P<0.001), retinopathy (r=-0.222, P=0.006), serum BUN (r=- 0.161, P=0.049), and a positive correlation with eGFR (r=0.250, P=0.002). Conclusions: The fact that ELA levels are higher in healthy individuals compared to diabetic patients without microalbu- minuria, and higher in diabetic patients without microalbuminuria compared to patients with advanced albuminuria and kidney damage, suggests that the ELA level can be an important clinical prognostic variable and even a promising agent for the treatment of diabetic nephropathy patients.
