BackgroundMycophenolate mofetil is a commonly used salvage therapy for patients with autoimmune hepatitis (AIH).
AimTo evaluate the predictors of response to mycophenolate rescue therapy to facilitate clinical decision making.
MethodsWe performed a retrospective observational cohort study of AIH patients managed in 17 major Australian liver centres who received mycophenolate after an inadequate response or intolerance to corticosteroids with/without thiopurine(s). Baseline demographic, clinical and laboratory variables were compared between responders and nonresponders. A multivariable logistic regression model was developed using forward selection to identify independent predictors of treatment response.
ResultsA total of 105 patients received mycophenolate rescue therapy of whom 63 (60%) achieved biochemical remission. On univariable analysis, older age (P=0.003), INR
ConclusionMycophenolate remains an excellent treatment option for patients with AIH refractory to or intolerant of standard therapy with those most likely to benefit being older and/or having lower pre-treatment IgG levels.
