Clinical efficacy of biocellulose, carboxymethyl cellulose and normal saline dressing in epidermolysis bullosa.

ABSTRACT

OBJECTIVE: To evaluate the efficacy of a biocellulose, a carboxymethyl cellulose and a normal saline wound dressing in the wound care management of epidermolysis bullosa (EB) skin wounds. METHODS: This was a single-blind, randomised controlled trial involving wounds from patients with EB. Wounds were divided into three groups group I with biocellulose wound dressing, group II with carboxymethyl cellulose wound dressing and group III with normal saline wound dressing as a control. All dressing changes and wound parameters were recorded. Observations were conducted every three days until complete wound closure or up to one month. RESULTS: The outcomes of treatment of 36 wounds from four patients were evaluated in this study. Mean healing time in group I was seven days, eight days in group II and 14 days in group III. There were significant differences in healing times between group I and group III (p=0.0001) and between group II and III (p=0.001). The results showed a significant reduction in the percentage of wounds area on day three for each group 51.7% in group I, 51.9% in group II, and 26% for group III. All wounds in groups I and II had healed at day 12 (100%) and at day 24 (100%) in group III. There were significant differences in the reduction of percentage wound area between group I and group III at day three (p=0.044) and day six (p=0.000), and between group II and III at day six (p=0.003). CONCLUSION: The study demonstrates that both the biocellulose and the carboxymethyl cellulose wound dressings significantly reduced percentage wound areas and complete healing times compared with the normal saline wound dressing in EB skin wounds, demonstrating they are both equally good for wound care management in EB patients.
