Abstract
BACKGROUND
Psoriasis is a common chronic, immune-mediated inflammatory skin disease. Despite the availability of several systemic therapeutic agents, treatment of psoriasis remains a challenge because of the associated adverse effects and/or the financial burden of these medications, given the chronicity of the disease.
OBJECTIVES
We aimed to compare the efficacy and safety of combined pulse azathioprine (AZA) and low-dose methotrexate (MTX) vs. a conventional dose of MTX in patients with chronic plaque psoriasis.
METHODS
In this randomized controlled trial, 67 patients with moderate-to-severe plaque psoriasis were randomized into two groups, receiving either combined pulse AZA (300 mg weekly dose) and low-dose MTX (10 mg weekly) or conventional-dose MTX (0.3 mg kg-1 per week) for 16 weeks. Patients were assessed for treatment response using the Psoriasis Area and Severity Index (PASI) score and for the development of any adverse effects at weeks 12 and 16, and for a further 3 months after stopping treatment.
RESULTS
A statistically significantly higher proportion of the patients receiving combined pulse AZA and low-dose MTX achieved ≥ 90% improvement in PASI and 100% improvement (PASI 100) at week 12, and PASI 100 at week 16, compared with those receiving the conventional dose of MTX as monotherapy. No serious adverse events were reported during the entire study period in the two groups.
CONCLUSIONS
Combination therapy using pulse AZA and low-dose MTX can be an efficacious treatment for moderate-to-severe plaque psoriasis, with a relatively good safety profile.
