Effect of Traditional Chinese Medicine plus narrow-band medium-wave ultraviolet B radiation on moderate-to-severe psoriasis vulgaris in a case series.

OBJECTIVE: To investigate the efficacy and safety of Traditional Chinese Medicine (TCM) therapy combined with ultraviolet B light therapy in the treatment of moderate-to-severe psoriasis. METHODS: Patients with moderate-to-severe psoriasis (skin lesion area > 10% of the body surface area) for 2 consecutive years were treated with TCM (oral and external use of herbal medicines, acupuncture, and herbal bathing) and narrow-band medium-wave ultraviolet B light treatment for 12 weeks. The treatment effect was evaluated based on the Psoriasis Area Severity Index (PASI), the achievement of a 50% reduction in the PASI (PASI50), the achievement of a 75% reduction in the PASI (PASI75), pruritus score, Dermatology Life Quality Index, and safety. RESULTS: A total of 95 outpatients were enrolled, and 92 subjects (96.8%) completed the 12-week treatment course. At baseline, the average proportion of the body surface area covered by skin lesions was 12.4%, and the average PASI was 17.7. All patients had previously been treated with conventional medicine (89.1% of patients received ultraviolet light treatment, 50.0% received glucocorticoids, and 21.7% received acitretin). After the 12-week treatment course, 22 patients (23.9% ) achieved PASI75, and 43 (46.7%) achieved PASI50. The post-treatment pruritus score and Dermatology Life Quality Index of all treated patients were significantly lower than the respective baseline values (P < 0.0001). No adverse effects were detected by the monitoring of blood, urine, stools, liver and kidney function, and echocardiography. CONCLUSION: Comprehensive therapy comprising TCM therapy combined with ultraviolet B light therapy achieved good outcomes for patients with moderate-to-severe psoriasis. (C) 2019 JTCM.
