A pragmatic non-invasive assessment of liver fibrosis in patients with psoriasis, rheumatoid arthritis or Crohn's disease receiving methotrexate therapy.

Background And Aims: The reported hepatotoxicity of methotrexate underlines the need for a repeated non-invasive and reliable evaluation of liver fibrosis. We estimated, using a non-invasive strategy, the prevalence of significant liver fibrosis in patients treated by methotrexate and the predictors of significant fibrosis (fibrosis≥F2).

Methods: Fibrosis was prospectively evaluated using 9 non-invasive tests in consecutive patients with psoriasis, rheumatoid arthritis, or Crohn's disease.
