In patients with primary biliary cholangitis (PBC), patient age, but not sex, is associated with response to ursodeoxycholic acid (UDCA) and transplant-free survival. This according to a longitudinal analysis of 4,355 adults in the Global PBC Study cohort, collected from 17 centers across Europe and North America. Researchers evaluated the effects of sex and age on response to UDCA treatment and transplant-free survival using logistic regression and Cox regression analyses, respectively. The found:
- Younger age at time of PBC diagnosis was associated with increased risk of failure treatment, liver transplant, and death.
- The greatest odds of response to UDCA were observed in patients aged >65 years.
- Risk of liver transplant or death decreased significantly with advancing age.
- Sex was not independently associated with response or transplant-free survival.
