    Author: Sakthiswary R, Suresh E.
    Journal: Lupus; 2014 Mar; 23(3):225-35. PubMed ID: 24399812.
    Abstract:
    OBJECTIVE: The objective of this review is to evaluate the evidence for efficacy of methotrexate (MTX) in systemic lupus erythematosus (SLE). METHODS: A comprehensive, computerized search was performed in MEDLINE (PubMed), EMBASE and the Cochrane Controlled Trials registry to screen for studies that examined the efficacy of MTX in adult SLE patients. The Jadad scoring system was used to assess study quality, and data were pooled using the random effects model. RESULTS: Of the 53 articles that were identified, 44 were excluded. Nine studies (including three randomized controlled and six observational) were eligible for inclusion. All of the included studies predominantly involved patients with arthritis or mucocutaneous features. There was significant reduction of the SLE Disease Activity Index (SLEDAI) among MTX-treated patients when compared with controls (p = 0.001, odds ratio (OR) 0.444, 95% confidence interval (CI) 0.279 to 0.707). There was also significant reduction in the average dose of corticosteroids among MTX-treated patients when compared with controls (p = 0.001, OR 0.335, 95% CI 0.202 to 0.558). The effect of MTX on laboratory and serological markers, including erythrocyte sedimentation rate, anti-dsDNA and complement levels (C3 and C4), could not be determined because of the limited numbers of controlled trials. CONCLUSION: The use of MTX is associated with significant reductions in SLEDAI and the average dose of corticosteroids in adult patients with SLE.
