Successful cessation of tumor necrosis factor inhibitor treatment in rheumatoid arthritis patients and potential predictors for early flare: An observational study in routine clinical care
Objectives: To investigate the prevalence and the consequence of tumor necrosis factor inhibitor (TNFi) cessation after clinical improvement in rheumatoid arthritis (RA) patients in clinical practice and predictors of flare after TNFi cessation.
Methods: We retrospectively assessed the prevalence of TNFi cessation after achieving sustained improvement, disease flare and joint damage progression after TNFi cessation in consecutive RA patients who started TNFi due to insufficient response to methotrexate were studied. Predictors for flare after TNFi cessation were investigated using Cox regression analysis.
Results: In 135 patients who started TNFi with methotrexate, 95 stopped TNFi after sustained improvement and continued methotrexate thereafter. Over 1 year, 33 patients had a flare and 26 restarted TNFi therapy. In 78 patients whose radiographs adequate for evaluation were available, 73 did not exhibit joint damage progression. Female gender, smoking, the interval from starting methotrexate to starting TNFi of more than 9 months and glucocorticoid use at starting TNFi were independently associated with shorter time to flare.
Conclusion: Sixty-five percent of patients were successfully discontinued TNFi over 1 year. Radiographic joint damage progression was rare. Early intervention with TNF inhibitor may contribute to successful TNF inhibitor cessation in patients with insufficient response to methotrexate.Key message
