If a deep dermal wound in a patient with peripheral vascular disease develops a chronic non-healing ulcer, which consequence is the MOST likely to prolong the inflammatory phase?

A)Accelerated keratinocyte migration to resurface
B)Elevated fibroblast proliferation and collagen deposition
C)Uncontrolled matrix metalloproteinase (MMP) activity reduction
D)Persistent neutrophil infiltration and reactive oxygen species production

💡 Explanation

Chronic non-healing wounds in patients with vascular disease often remain in a prolonged inflammatory phase because inadequate blood supply prevents efficient clearance of debris and inflammatory cells. This results in persistent neutrophil infiltration, causing continued reactive oxygen species production and tissue damage; therefore, prolonged inflammation results rather than a shift to the proliferative phase because of impaired resolution signals.
