Psoriatic patients with chronic viral hepatitis do not have an increased risk of liver cirrhosis despite long-term methotrexate use: Real-world data from a nationwide cohort study in Taiwan - 19/09/18
, Der-Yuan Chen, MD, PhD d, e, ⁎ Abstract |
Background |
Methotrexate (MTX) is commonly used in the treatment of patients with moderate-to-severe psoriasis.
Objective |
We conducted a nationwide population-based cohort study to investigate the impact of long-term MTX use on the risk of chronic viral hepatitis–related cirrhosis among psoriatic patients in Taiwan.
Methods |
This study obtained data from the National Health Insurance Research Database in Taiwan. We identified 2417 psoriatic patients with chronic hepatitis B (CHB) (370 MTX users and 2047 nonusers of MTX) and 1127 psoriatic patients with chronic hepatitis C (CHC) (174 MTX users and 953 nonusers of MTX) from January 1, 2000, to December 31, 2010.
Results |
After a mean follow-up of more than 9 years since the diagnosis of chronic viral hepatitis, a total of 125 patients with CHB (5%) and 120 patients with CHC (11%) developed liver cirrhosis. Comparable proportions of MTX users and nonusers of MTX developed liver cirrhosis (4% vs 5% in patients with CHB and 11% vs 11% in patients with CHC [both P >.05]).
Limitations |
There is possible selection bias and medication nonadherence.
Conclusion |
Our real-world data show that long-term MTX use may not be associated with an increased risk of liver cirrhosis among psoriatic patients with chronic viral hepatitis.
