OBJECTIVE: To systematically review possible predictors of successful discontinuation of biologic or targeted synthetic DMARDs (b/tsDMARDs) in RA patients in remission or low disease activity.

METHODS: MEDLINE database and Cochrane Library were scanned for studies that discontinued b/tsDMARDs in remission/low disease activity and searched for predictors of successful discontinuation. Additionally, EULAR and ACR meeting abstracts were hand searched.

RESULTS: Thirty-four studies with a total of 5724 patients were included. Predictors of successful b/tsDMARD discontinuation were (number of studies): low disease activity (n = 13), better physical function (n = 6), low or absence of rheumatoid factor (n = 5) or ACPA (n = 3), low levels of CRP (n = 3) or ESR (n = 3), shorter disease duration (n = 3), low signals of disease activity by ultrasound (n = 3). Only one study with high risk of bias was identified on tsDMARD discontinuation.

CONCLUSION: Several predictors of successful bDMARD discontinuation were identified. Although studies are heterogeneous, these predictors may inform clinical decision making in patients who are considered for a potential bDMARD discontinuation.
