Abstract
OBJECTIVE AND DESIGN: The treatment of recurrent rosacea has always been a problem. Oral minocycline has been widely used in the treatment of rosacea. However, the efficacy and safety of ozonated hydrotherapy combined with LED yellow light irradiation and oral minocycline for mild to moderate papulopustular rosacea (PPR) has not been thoroughly studied. METHODS: Patients with rosacea who met the criteria and had complete clinical statistic admitted to our hospital from April 2021 to September 2022 were retrospectively collected and divided into combined therapy group and oral only group. The patients in the two groups were treated with minocycline for 8 weeks. In addition, the patients in combined therapy group were treated with ozone hydrotherapy once a week, followed by LED yellow light irradiation for a total of 4 weeks. The Investigator' s global assessment (IGA) score was used to assess the condition. The efficacy was evaluated using the patients' subjective symptom scores. Skin lesion images and adverse reactions were recorded. The recurrence rate was observed after 24 weeks of follow-up. RESULTS: A total of 39 patients included in the study. After 4 weeks of treatment, the effective rate was 90% in combined therapy group and 52.63% in oral only group (p<0.05). After 8 weeks of treatment, the total score of the patients' subjective symptom scores and the scores of itching and burning sensation in combined therapy group were lower than those in oral only group (p<0.05). After 24 weeks of follow-up, the recurrence rate of combined therapy group was 5%, and that of oral only group was 26.32%. The mild adverse reactions experienced by both groups disappeared during follow-up. CONCLUSION: This combination therapy has a significant, rapid and safe therapeutic effect, especially in relieving itching and burning sensations, and may reduce the recurrence rate.
