Effect of Korean medicine as add-on therapy to phototherapy for psoriasis: Two case reports.
Psoriasis is a common chronic, immune-mediated inflammatory skin disease. Here, we describe 2 patients who presented with psoriasis to illustrate the potential efficacy of Korean medicine treatment combined with phototherapy. A 33-year-old female (Case 1) and a 37-year-old male (Case 2) presented at the clinic with symptoms of itching, erythema, and scaliness. Both patients were diagnosed with psoriasis based on the locations of erythema, as well as the appearance of circumscribed scaly papules and plaques. Patients underwent 5 months (Case 1) and 8 months (Case 2) of treatments with acupuncture, herbal medicine, probiotics, and phototherapy. After treatment, the patients improved in Psoriasis Area and Severity Index score from 7 to 1.2 (Case 1), and 23.2 to 2.2 (Case 2). These outcomes suggest that Korean medicine therapies combined with phototherapy may be effective for resolution of psoriasis; however, further research is needed to confirm these findings.
