Tang KT, et al. - Experts intended to analyze the impact of long-term methotrexate (MTX) use on the risk of chronic viral hepatitis-related cirrhosis among psoriatic patients in Taiwan. They selected psoriatic patients with chronic hepatitis B (CHB) (370 MTX users and 2047 MTX non-users) and psoriatic patients with chronic hepatitis C (CHC) (174 MTX users and 953 MTX non-users) from January 1, 2000 to December 31, 2010. Yielded data demonstrated that long-term MTX use was possibly not related to an increased risk of liver cirrhosis among psoriatic patients with chronic viral hepatitis.
