PBC
A new criterion of evaluating UDCA responses at 1 month was established as: ALP ≤ 2.5 × upper limit of normal (ULN) and AST ≤ 2 × ULN, and TBIL ≤ 1 × ULN (Xi’an criterion). The 5 year adverse outcome-free survival rate of UDCA responders, defined by Xi’an criterion, was 97%, which was significantly higher than that of those non-responders (64%). An accurate distinguishing high-risk patients’ capacity of Xi’an criterion was confirmed in both early and late-stage PBC.
