초록
Background: Over the past decade, combination therapies have become a mainstay of dermatologic care in psoriasis. Combination therapies are often more effective and safer than large dose single-agent therapies. With the emergence of new biologic therapies, dermatologists now have a wider array of tools to treat psoriasis. Although much data exists regarding cyclosporine or biologic agents alone for psoriasis,little is known about the efficacy, safety and tolerability of combination regimens. Objective: We designed a study to evaluate the efficacy and safety of etanercept and cyclosporin combination therapy in patients with refractory psoriasis. Methods: We administered oral cyclosporine (200mg daily) and subcutaneous etanercept 50 mg weekly injections until symptoms improved, then maintained treatment at a reduced dose. Seven patients with refractory psoriasis were evaluated 4 weekly. Results: All 7 patients showed rapid responses to combination therapy. Mean Psoriasis Area and Severity Index reductions following conditioning therapy (mean: 6.85 weeks) and maintenance therapy (mean: 56.5 weeks) were 94.9% and 93.2%, respectively. Conclusion: Etanercept and low-dose cyclosporine combination therapy appears to be a safe and efficacious alternative treatment strategy for patients with refractory psoriasis. The combination induced rapid improvement in patients with refractory psoriasis and dramatically improved their quality of life. Clinical studies including larger patient cohort are required to validate the safety and efficacy of this combination therapy. (Ann Dermatol 22(2) 138∼142, 2010)
