Abstract

Objective: The wound bed score is a validated tool to monitor wound healing in chronic wounds, and depends on visual examination by trained personnel. This study describes the feasibility of adding some biochemical and immunohistochemical parameters to increase the objectivity and specificity of the wound bed score Method: Patients with chronic wounds on the lower leg with different durations were enrolled to assess the correlation between the wound bed score and specific wound-related biomarkers, namely MMP-9, MMP-2, NGAL, albumin, integrin α2/β1, and other histochemical (CD68, PK1, CD32, fractalkine, periostin) and immunocytochemical markers from biopsies and smears taken from wound edges and bed. Results: The study examined samples from 10 patients. Patients with an unfavourable wound bed score had a low expression of periostin and fractalkine in the wound bed tissue. CD68 PK1 showed a low or negative expression in the majority of the samples. Patients negative for CD68 PK1 were also negative for CD32. Principal component analysis revealed that the albumin level and the amount of proteins were associated with a high wound bed score. Two different subsets of patients could be discriminated either by integrin α2/β1 and albumin percentages or the MMP-9 and MMP-2 activities Conclusion: These preliminary results pave the way towards an improved wound status diagnosis and an advanced quality of wound care and management. These findings need confirming with a large number of patients and at different time points.
