There is a great individual variability of pharmacokinetic of infliximab in patients treated for ankylosing spondylitis (AS). Moreover, some patients have a treatment with methotrexate (MTX), others have not.

Thus, the aim of this study is to assess the effect of MTX on the pharmacokinetic properties of infliximab in 30 patients treated for AS, 15 with MTX, 15 without.
