Predicting remission in juvenile rheumatoid arthritis with methotrexate treatment.
Forty-nine children with a polyarticular course of juvenile rheumatoid arthritis treated with methotrexate (MTX) for at least one year were analyzed to identify clinical characteristics that would predict remission of arthritis after MTX treatment. Twenty-two children (45%) had remission of arthritis after a mean of 13.6 months of treatment and did not differ from the 27 with persistently active arthritis regarding years of disease before starting MTX, age starting MTX, maximum MTX dose, disease onset type, presence of radiographic joint destruction, concomitant treatment with hydroxychloroquine, sulfasalazine or prednisone, or presence of rheumatoid factor or antinuclear antibodies. Higher dose MTX, earlier treatment, genetic markers, and a standardized route of therapy may yield important information in future studies.
