Spondyloarthritis: A concept or a disease?

2022 French Society for Rheumatology (SFR) recommendations on the everyday management of patients with spondyloarthritis, including psoriatic arthritis

OBJECTIVE

Update the French Society for Rheumatology (SFR) recommendations on the everyday management of patients with spondyloarthritis, including psoriatic arthritis.

METHODS

Following standardized procedures, a systematic literature review was done by four supervised rheumatology residents based on questions defined by a task force of 16 attending rheumatologists. The findings were reviewed during three working meetings that culminated in each recommendation receiving a grade and the level of agreement among experts being determined.

RESULTS

Five general principles and 15 recommendations were developed. They take into account pharmacological and non-pharmacological measures along with treatment methods based on the dominant phenotype present (axial, articular, enthesitis/dactylitis) and the extra-articular manifestations (psoriasis, inflammatory bowel disease, uveitis). NSAIDs are the first-line pharmacological treatment in the various presentations. Conventional synthetic disease modifying antirheumatic drugs (csDMARDs) are not indicated in the axial and isolated entheseal forms. If the response to conventional treatment is not adequate, targeted therapies (biologics, synthetics) should be considered; the indications depend on the clinical phenotype and presence of extra-articular manifestations.

CONCLUSION

This update incorporates recent data (published since the prior update in 2018) and the predominant clinical phenotype concept. It aims to help physicians with the everyday management of patients affected by spondyloarthritis, including psoriatic arthritis.

Uveitis occurrence in early inflammatory back pain. Five years data from the prospective French nationwide DESIR cohort

OBJECTIVE

Uveitis is a frequent extra rheumatological manifestation in axial Spondyloarthritis (SpA). The aim of study was to evaluate the prevalence and incidence of uveitis over the first five years of a prospective nationwide cohort of patients with high suspicion of early axial SpA, and to evaluate its associated factors.

METHODS

DESIR is a prospective observational cohort of patients with recent onset inflammatory back pain (more than 3 months, less than 3 years), suggestive of axial SpA, All available factors in the database were compared between patients with and without uveitis at 5 years, by uni and then multivariate analysis. Baseline factors associated with new cases of uveitis occurrence over the 5 years were also analyzed.

SIGNIFICANCE

P less than 0.05.

RESULTS

After 5 years, 91 patients (out of 480 with complete follow-up) had at least one uveitis episode, giving an estimated prevalence of 18.9% [95% CI: 15.4-22.4]. In multivariate analysis, uveitis was significantly associated with dactylitis, and elevated ESR. New incident uveitis occurred in 31 cases over 5 years, giving an estimated incidence rate of 1.29 [0.84-1.74]/100 patient-years. Incidence of new uveitis was associated in multivariate analysis with baseline factors: diagnosis of SpA, sacro iliac MRI inflammatory SPARCC score, dactylitis, syndesmophyte score. No significant association was found with HLA-B27, DMARDs, BASDAI, ASDAS, BASFI.

CONCLUSION

Five-years data of the DESIR cohort allowed an estimation of incidence rate of uveitis of 1.3/100p-y; over five years, uveitis was associated with dactylitis, biologic and sacro iliac MRI inflammation.

Local sacroiliac injections in the treatment of spondyloarthritis. What is the evidence?

Local sacroiliac injections represent an available treatment option in spondyloarthritis (SpA). There is no synthetic data about efficacy of this procedure in SpA. The aim of this review is to analyze the available data of the literature of local sacroiliac injections in SpA.

METHODS

A Pubmed search of papers published after 1990 was performed.

RESULTS

Pubmed search retained 15 publications in spondyloarthritis, 12 with corticosteroids (total of 468 injections in 268 patients), including 2 small-sized controlled studies, and 3 with TNF blockers (24 patients in open studies). With steroids, the two controlled studies (with a total number of 30 patients only) demonstrated significant results over placebo. In open studies, good response was reported in more than 80% of the cases, with a mean duration of improvement over 8 months. Reduction of sacroiliac inflammation on MRI was also found in several studies after injection. There is no consensus about the technique of injection or the type of steroid injected. No particular safety concern was reported. Many limitations have to be considered in the interpretation of these results.

CONCLUSION

This kind of procedure should be kept in the therapeutic armament in the current setting of costly targeted systemic treatments of spondyloarthritis. However, definition of a clear position in the treatment strategy needs further well-conducted studies.

2018 update of French Society for Rheumatology (SFR) recommendations about the everyday management of patients with spondyloarthritis

OBJECTIVE

To update French Society for Rheumatology recommendations about the management in clinical practice of patients with spondyloarthritis (SpA). SpA is considered across the range of clinical phenotypes (axial, peripheral, and entheseal) and concomitant manifestations. Psoriatic arthritis is included among the SpA phenotypes.

METHODS

According to the standard procedure advocated by the EULAR for developing recommendations, we first reviewed the literature published since the previous version of the recommendations issued in June 2013. A task force used the results to develop practice guidelines, which were then revised and graded using AGREE II.

RESULTS

Four general principles and 15 recommendations were developed. The first four recommendations deal with treatment goals and general considerations (assessment tools and comorbidities). Recommendations 5 and 6 are on non-pharmacological treatments. Recommendation 7 is about nonsteroidal anti-inflammatory drugs, which are the cornerstone of the treatment, and recommendations 8 to 10 are on analgesics, glucocorticoid therapy, and conventional disease-modifying antirheumatic drugs. Biologics are the focus of recommendations 11 through 14, which deal with newly introduced drug classes, including their indications (active disease despite conventional therapy and, for nonradiographic axial SpA, objective evidence of inflammation) and monitoring, and with patient management in the event of treatment failure or disease remission. Finally, recommendation 15 is about surgical treatments.

CONCLUSION

This update incorporates recent data into a smaller number of more simply formulated recommendations, with the goal of facilitating their use for guiding the management of patients with SpA.
