OBJECTIVES: To evaluate the success rate of glucocorticoid discontinuation and to study which factors are associated with successful discontinuation.
METHODS: Data from two treat-to-target studies, BeSt (target Disease Activity Score (DAS) ≤2.4) and IMPROVED (target DAS <1.6), were evaluated for all patients initially treated with a tapered high dose of prednisone with conventional synthetic disease-modifying antirheumatic drugs. Prednisone was discontinued when DAS ≤2.4 was maintained for 28 weeks in BeSt and as soon as DAS was <1.6 in IMPROVED. Discontinuation was considered successful if the target was maintained at the next visit. Logistic regression analyses were performed to identify predictors of successful discontinuation. A mixed effects logistic regression model was used to assess whether primary versus secondary discontinuation was as successful.
RESULTS: In the BeSt study, 40% (47 of 93) of patients flared after primary prednisone discontinuation, and of the other 60% (56 of 93), 38% had to restart later. Of those who restarted (secondary discontinuation), 47% (17 of 35) again flared. In IMPROVED, after primary discontinuation 39% (158 of 400) flared, and of the other 61% (242 of 400), 40% had to restart later. After secondary discontinuation 49% (68 of 139) flared. Only in IMPROVED a secondary attempt was less successful (BeSt OR 0.71, p=0.45; IMPROVED OR 0.60, p=0.01). A lower DAS both at baseline and stop visit and male gender (in IMPROVED) were associated with successful primary discontinuation.
CONCLUSION: Primary glucocorticoid discontinuation resulted in direct loss of disease control in approximately 40% and secondary in 50% of patients. 'Standard' baseline characteristics seem insufficient to personalise the duration of temporary glucocorticoid bridging, but the DAS at the time of discontinuation might provide guidance.
