Negative Pressure Occlusion Drainage + Silver Ion Dressing Reduces Inflammatory Factors and Improves DFU Healing
Summary: A new randomized study published in Frontiers in Endocrinology shows that combining negative pressure wound therapy (NPWT) with silver-ion dressings significantly lowers pro-inflammatory cytokines IL-6 and TNF-α in diabetic foot ulcers while achieving faster wound closure and higher healing rates compared to conventional dressings. The dual approach tackles both bacterial burden and excessive inflammation — two major barriers in chronic DFU management.
Key Highlights:
- Intervention: NPWT + silver-ion dressing vs standard care.
- Biomarkers: ↓ IL-6, ↓ TNF-α (p<0.05).
- Clinical: Faster closure, higher complete healing rate.
- Mechanism: Reduced infection + controlled inflammation.
