EULAR recommendations for the management of psoriatic arthritis with pharmacological therapies: 2023 update

Objective: New modes of action and more data on the efficacy and safety of existing drugs in psoriatic arthritis (PsA) required an update of the EULAR 2019 recommendations for the pharmacological treatment of PsA.

Methods: Following EULAR standardised operating procedures, the process included a systematic literature review and a consensus meeting of 36 international experts, in April 2023. Levels of evidence and grades of recommendations were determined.

Results: The updated recommendations comprise 7 overarching principles and 11 recommendations, and provide a treatment strategy for pharmacological therapies. Non-steroidal anti-inflammatory drugs should be used in monotherapy only for mild PsA and short-term; oral glucocorticoids are not recommended. In patients with peripheral arthritis, rapid initiation of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) is recommended, and methotrexate preferred. If the treatment target is not achieved with this strategy, a biological (bDMARD) should be initiated, without preference among modes of action. Relevant skin psoriasis should orient towards bDMARDs targeting IL-23p40, IL-23-p19, IL-17A and IL-17A/F inhibitors. In case of predominant axial or entheseal disease, an algorithm is also proposed. Use of Janus kinase-inhibitors is proposed primarily after bDMARD failure taking relevant risk factors into account, or in case bDMARDs are not an appropriate choice. Inflammatory bowel disease and uveitis, if present, should influence drug choices with monoclonal TNF inhibitors proposed. Drug switches and tapering in sustained remission are also addressed.

Conclusion: These updated recommendations integrate all currently available drugs in a practical and progressive approach, which will be helpful for the pharmacological management of PsA.
