Introduction: Diabetic nephropathy (DN) represents one of the main causes of end-stage renal disease in type 2 diabetes mellitus (DM) patients. Galectin-3 has been implicated in pathogenesis of many pathological conditions. To date, there are limited data regarding the relationship between galectin-3 and DN. 
Aim of the study: Evaluation of serum galectin-3 as a novel prognostic biomarker in patients with DN. 
Patients and methods: This prospective study was carried out in the Internal Medicine and Clinical Pathology Departments, Tanta University Hospital, Egypt, from March 2015 to March 2018 on 300 patients with type 2 DM. Patients were divided into three groups: group I included 100 patients with albumin/creatinine ratio (ACR) 300 mg/g (macroalbuminuria). All patients were subjected to the following: full history taking, clinical examination, and laboratory evaluation (HbA1c, creatinine, estimated glomerular filtration rate, ACR, and serum galectin-3).
Results: The mean levels of galectin-3 were significantly higher in patients with macroalbuminuria than in those with microalbuminuria and normoalbuminuria. Galectin-3 was a significant predictor for progression to microalbuminuria, macroalbuminuria, dialysis, and death among patients with type 2 DM.
Conclusion: Based on this single center prospective study, serum galectin-3 is considered a significant predictor for DN progression among patients with type 2 DM.
