The Advantage of Cyclosporine A and Methotrexate Rotational Therapy in Long-Term Systemic Treatment for Chronic Plaque Psoriasis in a Real World Practice

ABSTRACT

BACKGROUND: Psoriasis is a chronic inflammatory disease. In the treatment of psoriasis, cyclosporine is commonly prescribed systemic agents. However, long-term use of cyclosporine is not recommended because of side effects such as nephrotoxicity or hypertension. OBJECTIVE: To ascertain the improved safety of rotational therapy using cyclosporine and methotrexate, we investigated the frequency of abnormal results in laboratory test after long term rotational therapy using cyclosporine and methotrexate. METHODS: From January 2009 to June 2014, patients who were treated with cyclosporine or methotrexate were enrolled. The clinical data and usage of medications were reviewed. Laboratory tests were conducted before starting the treatment and regularly follow-up. The occurrences of any laboratory abnormalities during the treatments were investigated. RESULTS: A total of 21 psoriatic patients were enrolled. The mean of medication period and cumulative dose of cyclosporine and methotrexate were 497.81±512.06 days and 115.68±184.34 g in cyclosporine and 264.19±264.71 days and 448.71±448.63 mg in methotrexate. Laboratory abnormalities were found in total two patients after rotational therapy two patients (9.5%) in aspartate aminotransferase/alanine aminotransferase and one patient (4.8%) in uric acid. No laboratory abnormalities were found in renal function test. CONCLUSION: We found that the rotational approaches using cyclosporine and methotrexate reduced the possibility of the development of nephrotoxicity. In addition to other advantage such as quick switching from one agent to another, the rotational therapy using cyclosporine and methotrexate can minimize the adverse events during the systemic treatment of chronic plaque psoriasis.
