Abstract

Oral methotrexate in the treatment of psoriasis may cause gastrointestinal side effects or inadequate response in some patients. There are many studies in rheumatoid arthritis and juvenile rheumatoid arthritis that subcutaneous methotrexate administration could be more effective and less gastrointestinal side effects than oral administration.  But in psoriasis, there is no study before.

This is a prospective study in 13 psoriasis patients that had had gastrointestinal side effects or inadequate response after weekly oral methotrexate treatment.  The treatment was changed from oral form to subcutaneous injection at the same dose.  The clinical efficacy was assessed in 1-4 months.  The results showed that 3 patients (23%) had achieved PASI-25, 4 patients (31%) had achieved PASI-50 and 3 patients (23%) had achieved PASI-75. The gastrointestinal side effects assessment showed that 11 patients (85%) had no symptom and 2 patients (15%) had mild nausea.  On satisfaction scale of 1-5, the average rating was 3.84, indicated that patients were rather very satisfied with the treatment of subcutaneous methotrexate.

From this study it may be concluded that subcutaneous methotrexate could be more effective and less gastrointestinal side effects than oral methotrexate in the treatment of psoriasis.
