Abstract: Objective To investigate the association of serum levels of pentosidine, soluble receptor for advanced glycation end products (sRAGE) with sarcopenia in elderly patients with type 2 diabetes mellitus (T2DM). Methods A total of 136 T2DM patients aged over 60 years admitted to Department of Endocrinology of Baoding NO.1 Central Hospital from June 2024 to May 2025 were enrolled and divided into sarcopenic group (42 cases) and non-sarcopenic group (94 cases) based on the Asian Working Group for Sarcopenia criteria. The general information and biochemical indicators were collected, and serum levels of pentosidine and sRAGE were measured by enzyme-linked immunosorbent assay (ELISA).Multivariate logistic regression was applied to identify independent factors associated with sarcopenia in the elderly T2DM patients. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of serum pentosidine and sRAGE for sarcopenia in the elderly T2DM patients. Results Compared with the non-sarcopenic group, the patients in sarcopenic group had significantly higher age, diabetes duration, glycated hemoglobin (HbA1c), and serum pentosidine levels, while their body mass index (BMI), albumin (ALB), triglyceride (TG), and sRAGE levels were lower (P<0.05). Logistic regression analysis showed that low BMI(OR=0.767, 95%CI: 0.634-0.929), high pentosidine levels (OR=1.018, 95%CI: 1.007-1.029), and low sRAGE levels(OR=0.994, 95%CI: 0.991-0.997)were independent risk factors for sarcopenia in elderly T2DM patients (P<0.05). The area under the ROC curve for the combination of serum pentosidine and sRAGE was 0.881 (95%CI: 0.815-0.947) in predicting sarcopenia in elderly patients with T2DM,which was significantly better than that of either single indicator (P<0.05). Conclusions Serum levels of pentosidine and sRAGE are closely related to sarcopenia in elderly T2DM patients. The combination of the two indicators has excellent efficacy in identifying sarcopenia in elderly T2DM patients, suggesting their potential utility as auxiliary diagnostic biomarkers.
