An evaluation of Hyalofill-F plus compression bandaging in the treatment of chronic venous ulcers.

Abstract

Hyaluronan, a component of the extracellular matrix, plays a significant role in several aspects of tissue repair and the wound healing process. In this Italian study Hyalofill-F, a partial benzyl ester derivative of hyaluronan, used in combination with compression bandaging, was compared with the well-established therapy in Italy of non-adherent gauze plus compression therapy in the treatment of chronic venous leg ulcers. Hyalofill-F plus compression bandaging performed significantly better than non-adherent gauze plus compression bandage in all of the clinically relevant efficacy parameters. Mean reduction in ulcer area in the hyaluronan-derivative group was 8.1 cm2 after eight weeks of treatment, compared with 0.4 cm2 in the comparator group. The resulting difference of 7.7 cm2 between the two groups was statistically significant (p = 0.0019). Furthermore, statistically significant results in favour of the hyaluronan-derivative group were obtained in the following: speed of epithelialisation; leveling of the margins; degree of maceration; pain intensity and frequency. Hyalofill-F plus compression bandaging resulted in an earlier and greater decrease in ulcer area compared with non-adherent gauze plus compression bandaging, therapy supporting its use in the treatment of chronic venous ulcers.
