Popis: Background:Discontinuation of glucocorticoids (GC) as bridging therapy in rheumatoid arthritis (RA) treatment is recommended as rapidly as clinically feasible. Little is known about the rate of, and possible characteristics associated with successful GC discontinuation.Objectives:To evaluate the success rate of GC discontinuation, and to study which factors are associated with successful GC discontinuation.Methods:Data from two treat-to-target studies; BeSt (target DAS ≤2.4, LDA), and IMPROVED (target DAS Results:From the 131 patients initiating combination therapy with prednisone in the BeSt study, 93 attempted discontinuation. Primary discontinuation was successful in 60% (56/93) and secondary discontinuation in 54% (19/35). A lower DAS at the visit prior to GC discontinuation and ACPA negativity were associated with successful discontinuation (table 1). Of the 610 patients in the IMPROVED, 400 attempted discontinuation. Primary discontinuation was successful in 61% (242/400), and secondary in 51% (71/139). A lower DAS both at baseline and at the visit prior to GC discontinuation were associated with successful discontinuation (table 1).Conclusion:Primary GCs discontinuation was successful in approximately 60% and secondary in 50% of patients, independent of the treatment target and associated threshold for GC discontinuation. Most baseline characteristics were not predictive of successful GC discontinuation, but ACPA negativity (only in BeSt), baseline DAS (only in IMPROVED) and in both studies DAS prior to GC discontinuation were predictive for successful discontinuation. Based on this data it seems that ‘standard’ baseline characteristics are insufficient to ‘personalize’ the duration of temporary GC bridging but the DAS at the moment of GC discontinuation might give guidance.Table 1.Results logistic regression analysesUnivariableMultivariableaR2= 0.173BeStOR (95% CI)p-valueOR (95% CI)p-valueAge, year1.00 (0.98; 1.03)0.98Gender, female0.51 (0.24; 1.09)0.08Symptom duration BL, weeks1.00 (0.99; 1.01)0.61DAS at BL0.92 (0.61; 1.40)0.70DAS prior to discontinuation0.13 (0.05; 0.33)0.11 (0.04; 0.30)RF, positive1.28 (0.62; 2.69)0.502.24 (0.81; 6,17)0.12ACPA, positive0.70 (0.34; 1.43)0.320.32 (0.12; 0.86)0.02Erosions, present at BL0.65 (0.28; 1.49)0.31UnivariableMultivariableaR2= 0.065IMPROVEDOR (95% CI)p-valueOR (95% CI)p-valueAge, year1.00 (0.99; 1.02)0.64Gender, female0.62 (0.43; 0.89)0.010.75 (0.51; 1.11)0.15Symptom duration BL, weeks1.00 (0.99; 1.00)0.430.99 (0.99; 1.00)0.08DAS at BL0.80 (0.65; 0.98)0.030.78 (0.62; 0.98)0.03DAS prior to discontinuation0.24 (0.15; 0.38)0.24 (0.14; 0.40)RF, positive0.82 (0.57; 1.17)0.27ACPA, positive0.95 (0.66; 1.35)0.76Erosions, present at BL0.80 (0.49; 1.29)0.35ACPA: anti-citrullinated protein antibodies; BL: baseline; DAS: disease activity score; RF: rheumatoid factor. α The final multivariable logistic regression model was based on stepwise forward and backward selection of predictors, both resulting in the same final model.Acknowledgements:We would like to thank all patients for their contribution as well as the rheumatologists who participated in the BeSt study group and in the IMPROVED-study group. We would also like to thank all other rheumatologists and trainee rheumatologists who enrolled patients in these studies, and all research nurses for their contributions.Disclosure of Interests:Johanna M.
