Clinical Report: The Role of Inflammation, Oxidative Stress, MMPs, and DNA Damage in DPNP
Overview
This study investigates the associations between inflammation, oxidative stress, matrix metalloproteinases (MMPs), DNA damage, and diabetic polyneuropathy (DPNP) and neuropathic pain (DNP) in patients with Type 2 diabetes mellitus.
Background
Diabetic polyneuropathy is a prevalent complication of type 2 diabetes mellitus, significantly impacting patient quality of life and increasing healthcare costs. Understanding the underlying mechanisms, including inflammation and oxidative stress, is crucial.

Key Findings
Diabetic patients exhibited significantly higher levels of IL-6, TNF-α, IL-1β, MMP-9, MMP-10, OSI, and DNA damage compared to healthy controls (p < 0.001).
All biomarkers except MMP-2 were significantly elevated in diabetic patients with DPNP and DNP (p < 0.001).
Strong correlations were observed among IL-6, TNF-α, IL-1β, MMP-9, and OSI levels in diabetic patients.
Multivariable analysis indicated that DPNP was independently associated with increased levels of MMP-9, MMP-10, and OSI.
DNP was independently associated with increased OSI levels.
Clinical Implications
Monitoring inflammatory and oxidative stress markers in patients with Type 2 diabetes may provide insights into the progression of diabetic neuropathy.
Conclusion
The findings highlight the role of inflammation, oxidative stress, and matrix metalloproteinases in the pathophysiology of diabetic polyneuropathy and associated neuropathic pain.
