BACKGROUND: Poorly healing wounds represent the primary health-related burden for hereditary recessive dystrophic epidermolysis bullosa (RDEB) patients. Contribution of wound-associated soluble constituents to wound progression remains not well defined.
OBJECTIVE: To conduct cross-sectional analysis of cytokine, chemokine, and growth factor in exudates from RDEB wounds and define changes associated with wound progression.
METHODS: Concentrations of selected cytokines, chemokines, and growth factors were evaluated by multiplex ELISA in eight blister fluids and 66 exudates from early, established, and chronic RDEB and five chronic venous ulcers (VU). A cross-sectional analysis was performed.
RESULTS: Our data demonstrated that proinflammatory CXCL8 and IL-1β tend to accumulate in established RDEB lesions. The levels of several interleukins including IL-17, IL-18, and IL-10 were significantly higher in RDEB chronic wounds than in VU. Contrary to VU and other chronic wounds, high levels of VEGF, G-CSF, and HGF growth factors were detected in RDEB established and chronic skin lesions.
CONCLUSION: Although this study is limited to cross-sectional analysis of wound exudates, detected high levels of specific pro-inflammatory, neutrophil-recruiting, and pro-angiogenic and pro-proliferative factors, such as IL-1β, CXCL8, VEGF, G-CSF, and HGF define RDEB wounds and offer potential pharmacological targets to improve wound healing in the patients.
