Abstract

AIM: To evaluate a moisturizer containing urea, glycerine and petrolatum for healing deep open fissures on the feet of people with diabetes. If left untreated, open fissures, an entry point for bacteria, can lead to infection, ulceration and further complications.

METHODS: This randomized, double-blind, multicentre study at 19 hospitals, general practices and diabetologists in France and Belgium included participants with diabetes and a deep open target fissure on their heel. Participants were randomized to test cream or placebo (1 : 1) for 4 weeks. Complete target fissure healing after 4 weeks (primary criterion) and 2 weeks, target fissure closure, overall fissure healing and xerosis were assessed.

RESULTS: Some 167 participants were randomized (80 to test cream; 87 to placebo); all were included in the efficacy analyses. The percentage of participants with complete target fissure healing after 4 weeks was higher with test cream than placebo (46.3% vs. 33.3%): the difference did not reach statistical significance (P = 0.088). Fewer participants still had a deep open target fissure with test cream than placebo, the difference was statistically significant and clinically relevant after 2 (24.7% vs. 42.7%, P = 0.027) and 4 weeks (6.4% vs. 24.1%, P = 0.002). The difference in overall fissure healing between test cream and placebo was significant (P < 0.001) and test cream resulted in greater xerosis improvement (P < 0.001 and P = 0.002 at 2 and 4 weeks, respectively).

CONCLUSION: The activity of the test cream for treating feet fissures of people with diabetes was confirmed by an improvement in open fissure healing and xerosis. The cream was well tolerated.

In this study, the activity of the test cream for treating feet fissures of people with diabetes was confirmed by an improvement in open fissure healing and xerosis. The clinical relevance of this finding, however, is marginal at best. As a dermatologist, I will not change my practice, and will continue treating these patients with regular moisturizers or urea cream.

Treatment of diabetic foot diseases is a big challenge. Although this is a small study, this test cream can be applied along with other management options. It's easy and cost effective.
