Abstract
Methotrexate is a widely used and efficacious treatment for psoriasis. Current recommendations advise liver biopsy after each cumulative 1–1.5g dosage of methotrexate. Although studies of methotrexate hepatotoxicity in psoriasis are of variable quality, the evidence indicates that in patients with no risk factors for liver disease on long-term, low-dosage (<20mg), once-weekly methotrexate, liver biopsy is justified after an initial cumulative dosage of 4g. Advances in the non-invasive assessment of liver fibrogenesis may eventually further reduce the need for biopsy.
