Curative Effect of 30% Supramolecular Salicylic Acid Combined with Yufa Spray Dressing on Moderate to Severe Scalp Seborrheic Dermatitis

Abstract

Objective: To observe the clinical efficacy of 30% supramolecular salicylic acid combined with Yufa spray dressing in the treatment of moderate to severe seborrheic dermatitis (seborrheic dermatitis of the scalp, SDS). Methods: From January 2020 to December 2021, 150 patients with SDS, who were treated in the Dermatology Clinic of the First Affiliated Hospital of Xi’an Medical University, were randomly divided into two groups, a treatment group and a control group, with 75 cases in each group. The treatment group was given 30% supramolecular salicylic acid combined with Yufa spray dressing on the basis of external medicine given to the control group, while the control group was given oral medicine combined with external medicine. Results: The difference in scores of erythema, scales, pruritus, and folliculitis of the treatment group before and after treatment was significant (P < 0.01), indicating that supramolecular salicylic acid combined with Yufa spray dressing can relieve the symptoms of SDS. The difference in scores of erythema of the control group before and after treatment was significant as well (P < 0.05), indicating that traditional antibiotics are also effective in treating SDS; however, there was no significant difference (P > 0.05) in the scores of other signs and symptoms, such as scales, pruritus, and folliculitis, before and after treatment, indicating that traditional antibiotics have no obvious curative effect on SDS. After 12 weeks of treatment, the improvement in erythema, scaling, and folliculitis was significantly greater in the treatment group compared with the control group (P < 0.05). Curative effect comparison showed that the total effective rate of the treatment group was 80.00%, compared with 25.67% of the control group, and the difference was statistically significant (P < 0.05). Conclusion: 30% supramolecular salicylic acid combined with Yufa spray dressing can significantly improve the therapeutic effect in moderate to severe SDS; the recurrence rate is lower, the course of treatment is shorted, and patients generally feel better; thus, it is a new option for the treatment of dermatitis.
