E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess differences in treatment effects between budesonide and prednisolone in non-cirrhotic newly diagnosed AIH patients with respect to time to remission and percentage of patients reaching complete and incomplete remission, and number of flares. |
|
E.2.2 | Secondary objectives of the trial |
To assess (i) the side effects of budesonide (BUD) vs prednisolone (PRED) regarding diabetes (ii) the side effects of BD vs PRED regarding osteoporosis (change at 1 year from baseline) (iii) the side effects of BUD vs PRED on body weight at week 26 and 52 (iv) the side effects of BUD vs PRED on the skin at week 26 and 52 (presence of striae, moon face, hirsutism at week 26 and 52) (v) the side effects of BUD vs PRED on QoL (SF36, SHS and WPAI-GH at baseline, week 4 and week 52) (vi) the effects of BUD vs PRED on liver biopsy (changes in scores from baseline to week 52) (vii) the effects of BUD vs PREDe on Fibroscan scores at week 13, 26 and 52. (viii) the effects of BUD vs PRED on inflammatory markers such as TNF, IL6 and genetic markers on inflammation at week 52 compared with baseline. (ix) the effects of BUD vs PRED on laboratory markers, such as ASAT, ALAT, GT, ALP, Bilirubin and IgG. |
