Study Arms:
- prednisone (Type: EXPERIMENTAL): • Patients enrolled into the study will be treated with prednisone, 20 mg/day (if body weight \<70 kg ; or 25mg/d if body weight \>70 kg) for 1 month, then tapered to 12.5 mg/d (month 2) and 7.5 mg/d (month 3) and stop. In both groups, patients will be treated according to expert advice including use of statins (according to French Health Agency recommendation), a RAS inhibitor and supportive treatment (including nutrition, treatment of heart failure, and dialysis).
- placebo (Type: PLACEBO_COMPARATOR): Patients enrolled into the study will be treated with placebo, 20 mg/day (if body weight \<70 kg ; or 25mg/d if body weight \>70 kg) for 1 month, then tapered to 12.5 mg/d (month 2) and 7.5 mg/d (month 3) and stop. In both groups, patients will be treated according to expert advice including use of statins (according to French Health Agency recommendation), a RAS inhibitor and supportive treatment (including nutrition, treatment of heart failure, and dialysis).

Based on this trial design, predict the completion outcome and termination type (if applicable).
