Healing of chronic cutaneous wounds by topical treatment with basic fibroblast growth factor.

Abstract

OBJECTIVE:

To evaluate the safety and efficacy of topical application of recombinant bovine basic fibroblast growth factor (rbFGF) on the healing of chronic cutaneous wounds.

METHODS:

Twenty-eight patients with thirty-three chronic cutaneous wounds resulting from trauma, diabetes mellitus, pressure sore and radiation injuries were enrolled in this prospective, open-label crossover trial. Prior to treatment with rbFGF, all wounds failed to heal with conventional therapies within 4 weeks. All wounds were locally treated with rbFGF at a dose of 150 AU/cm(2). Healing time and the quality of wounds were used to evaluate the efficacy of the treatment.

RESULTS:

Healing of all chronic wounds was expedited. During the study, eighteen wounds completely healed within 2 weeks, four healed within 3 weeks, and another eight completely healed within 4 weeks. Only three wounds failed to heal within 4 weeks, but healed at 30, 40 and 42 days after treatment with rbFGF. Thus, compared with conventional therapies, the effective rate of rbFGF treatment within 4 weeks was 90.9%. Histological assessment showed more abundant capillary sprouts or tubes and that fibroblasts were differentiated in wounds treated with rbFGF. No adverse side effects related to basic fibroblast growth factor were observed.

CONCLUSIONS:

Our results indicate that rbFGF could be used to accelerate healing in chronic wounds. It is our belief that this may be a more effective method of chronic wound management.
