Nutritional Interventions to Optimize Orthobiologic Therapy Quality in Type 2 Diabetes Mellitus: Molecular Mechanisms and Clinical Framework: A Narrative Review.

原始摘要

Type 2 diabetes mellitus (T2DM) affects approximately 10-25% of patients undergoing orthopedic procedures and is associated with impaired tissue healing, increased complication rates, and reduced responsiveness to orthobiologic therapies, including platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC), and mesenchymal stem cell (MSC) preparations. The underlying mechanisms include advanced glycation end-product accumulation, NF-κB-driven chronic inflammation, Nrf2 pathway impairment, mitochondrial dysfunction, and epigenetic diabetic memory, collectively compromising both orthobiologic product quality and the tissue microenvironment. Emerging, predominantly mechanistic evidence suggests that targeted nutritional interventions, including bioactive compounds targeting mitochondrial biogenesis pathways, anti-inflammatory dietary patterns, and specific micronutrients, may modulate these pathological processes and potentially improve orthobiologic outcomes. This narrative review synthesizes evidence from diabetic pathophysiology, orthobiologic outcomes research, and nutritional science to propose a conceptual clinical framework for regenerative medicine optimization in T2DM patients. Critical knowledge gaps are identified, and a research agenda is proposed. The proposed framework, based primarily on mechanistic and preclinical evidence, should be interpreted as a foundation for research prioritization and hypothesis generation rather than as a clinical protocol. Rigorous randomized trials directly evaluating nutritional optimization in orthobiologic therapy for diabetic patients are required before evidence-based recommendations can be established.
