Abstract

This letter comments on the study by Ge et al. Serum α1-microglobulin (α1-MG) was reported to be associated with diabetic nephropathy, retinopathy, peripheral neuropathy, and left ventricular hypertrophy. The letter further highlights the need for multicenter validation and evaluation of clinical applicability to clarify the role of α1-MG in diabetes management.

Keywords: α1-microglobulin; Type 2 diabetes mellitus; Machine learning models; Commentary

Core Tip: This letter comments on the recent study regarding serum α1-microglobulin (α1-MG) as a predictor of multiple complications in type 2 diabetes mellitus. The letter underscores the importance of α1-MG as a potential biomarker linking renal, retinal, neural, and cardiac complications, and highlights the need for multi-center validation and cost-effectiveness evaluation before clinical adoption.
