Aim: To access the effectiveness, safety and tolerance of methotrexate (MTX) in psoriatic arthritis (PsA) treatment.
Methods: We recruit 37 patients, admitted at HCMC Hospital of Dermato-Venereology from 1/2016 to 3/2017, with MTX dosage ranging from 10 mg to 15 mg per week.
Results: Skin lesion response after 12 weeks improved PASI 50: 40.5%, PASI 75: 24.3%. Disease activity score decreased after 12 weeks with ∆DAS28 = -1.43 + 0.79, 37.8% PsA achieved complete remission. Nausea and vomiting were 8.1%. These symptoms were mild and transient. We did not stop MTX usage. The rate of elevating SGPT 2-3 times as much as the upper limit of the normal range was 2.7%.
Conclusion: We finally demonstrated that the rate of treatment response in Vietnam is the same as demonstrated by foreign authors in other countries.
Keywords: Disease activity score (DAS); Psoriatic arthritis (PsA).
