2021 clinical practice guidelines for the diagnosis, treatment, and follow-up of patients with peripheral spondyloarthritis. Colombian Association of Rheumatology

ABSTRACT Background: Peripheral spondylarthritis is a chronic Inflammatory disease whose clinical presentation is related to the presence of arthritis, enthesitis and/or dactylitis. This term is used interchangeably with some of its subtypes such as psoriatic arthritis, reactive arthritis, and undifferentiated spondyloarthritis. Objective: To develop and formulate a set of specific recommendations based on the best available evidence for the diagnosis, treatment, and monitoring of adult patients with peripheral spondyloarthritis. Methods: A working group was established, clinical questions were formulated, outcomes were graded, and a systematic search for evidence was conducted. The guideline panel was multidisciplinary (including patient representatives) and balanced. Following the for mal expert consensus method, the GRADE methodology "Grading of Recommendations Assessment, Development and Evaluation" was used to assess the quality of the evidence and generate the recommendations. The clinical practice guideline includes ten recommendations related to monitoring of disease activity (n = 1) and treatment (n = 9). Results: In patients with peripheral spondyloarthritis, the use of methotrexate or sulfasalazine as the first line of treatment is suggested, and local injections of glucocorticoids are conditionally recommended. In patients with failure to cDMARDs, an anti TNFα or an anti IL17A is recommended. In case of failure to bDMARDs, it is suggested to use another bDMARD or JAK inhibitor. In patients with peripheral spondylarthritis associated with inflammatory bowel disease, it is recommended to start treatment with cDMARDs; in the absence of response, the use of an anti TNFα over an anti-IL-17 or an anti-IL-12-23 is recom mended as a second line of treatment. In patients with psoriatic arthritis, the combined use of methotrexate with a bDMARD is conditionally recommended for optimization of dosing. To assess disease activity in Psoriatic Arthritis, the use of DAPSA or MDA is suggested for patient monitoring. Conclusions: This set of recommendations provides an updated guideline on the diagnosis and treatment of peripheral spondyloarthritis.
