ABSTRACT

Objective:To investigate clinical efficacy of mucopolysaccharide polysulfate cream combined with sertaconazole nitrate cream in the treatment of scaly hyperkeratotic tinea pedis.Methods:From March 2019 to January 2020, 100 patients with scaly hyperkeratotic tinea pedis were enrolled into this study, and randomly and equally divided into 2 groups by using a random number table control group treated with topical sertaconazole nitrate cream alone at a dose of 0.5-1 g twice a day; combined group treated with topical mucopolysaccharide polysulfate cream at a dose of 0.5-1 g followed by topical sertaconazole nitrate cream at a dose of 0.5-1 g 30 minutes later, which were performed twice a day. The treatment lasted 4 weeks. The time to clinical symptom relief, efficacy and incidence of adverse reactions were compared between the two groups. Dermatology life quality index (DLQI) was assessed at 0, 2 and 4 weeks after the start of treatment. Two-independent-sample t test, repeated measures analysis of variance and chi-square test were used for statistical analysis. Results:After treatment, the time to pruritus relief and that to desquamation improvement were 6.05 ± 1.98 and 12.03 ± 3.92 days respectively in the combined group, which were significantly shorter than those in the control group (8.39 ± 2.11, 15.11 ± 4.05 days, t = 5.72, 3.86, respectively, both P < 0.001) . During the 4 weeks of treatment, DLQI scores gradually decreased in both the 2 groups (all P < 0.001) , which were significantly lower in the combined group than in the control group at weeks 2 and 4 (both P < 0.001) . After 4-week treatment, the total response rate was 98% (49/50) in the combined group, significantly higher than that in the control group (82%, 41/50; χ2= 7.11, P= 0.007) . There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05) . Conclusion:Mucopolysaccharide polysulfate cream can improve the efficacy of sertaconazole nitrate cream in the treatment of scaly hyperkeratotic tinea pedis.
