Dexamethasone‐induced healing of chronic leg ulcers in a patient with defective organization of the extracellular matrix of fibronectin

Previous investigations have shown that skin fibroblasts derived from patients affected by Ehlers–Danlos syndrome (EDS) lack an organized extracellular matrix (ECM) of fibronectin (FN). As retarded wound healing is a sign of EDS, we hypothesized that a young healthy man suffering from chronic recalc...

Zusammenfassung:Previous investigations have shown that skin fibroblasts derived from patients affected by Ehlers–Danlos syndrome (EDS) lack an organized extracellular matrix (ECM) of fibronectin (FN). As retarded wound healing is a sign of EDS, we hypothesized that a young healthy man suffering from chronic recalcitrant leg ulcers might be affected by a defect of FN–ECM organization similar to that observed in EDS. Immunofluorescence of cultured skin fibroblasts obtained from skin biopsies from the patient and a control demonstrated that the patient’s fibroblasts lacked FN–ECM organization, in contrast with those of the control; this was restored by 10−7 mol/L dexamethasone (DEX) in vitro. DEX treatment of the patient was associated with healing of his leg ulcers. In conclusion, DEX may be effective in reversing impaired wound healing associated with a lack of FN–ECM organization
