The Association between Serum Neutrophil Gelatinase-Associated Lipocalin and Depression in Patients with Type 2 Diabetes Mellitus.

Background: Patients wtih type 2 diabetes mellitus (DM) have an increased risk of depressive symptoms. Whether serum neutrophil gelatinase-associated lipocalin (NGAL) is associated with depressive symptoms in old patients with type 2 DM is still uncertain.

Objective: We aim to investigate whether serum NGAL levels were associated with elevated risk of depressive symptoms in patients with type 2 DM in an old population.
