Objective: To update the consensus document of the Spanish Society of Rheumatology (SER) regarding the use of targeted biological and synthetic therapies in rheumatoid arthritis (RA) with the aim of assisting clinicians in their therapeutic decisions. Methods: A panel of 13 experts was assembled through an open call by SER. We employed a mixed adaptation-elaboration-update methodology starting from the 2015 Consensus Document of the Spanish Society of Rheumatology on the use of biological therapies in RA. Starting with systematic reviews (SR) of recommendations from EULAR 2019, American College of Rheumatology 2021, and GUIPCAR 2017, we updated the search strategies for the PICO questions of GUIPCAR. An additional SR was conducted on demyelinating disease in relation to targeted biological and synthetic therapies. Following the analysis of evidence by different panelists, consensus on the wording and level of agreement for each recommendation was reached in a face-to-face meeting. Results: The panel established 5 general principles and 15 recommendations on the management of RA. These encompassed crucial aspects such as the importance of early treatment, therapeutic goals in RA, monitoring frequency, the use of glucocorticoids, the application of conventional synthetic disease- modifying antirheumatic drugs (csDMARDs), biological DMARDs (bDMARDs), and targeted synthetic DMARDs. Additionally, recommendations on dose reduction of these drugs in stable patients were included. This update also features recommendations on the use of bDMARDs and Janus Kinase inhibitors in some specific clinical situations, such as patients with lung disease, a history of cancer, heart failure, or demyelinating disease. Conclusions: This update provides recommendations on key aspects in the management of RA using targeted biological and synthetic therapies.
