P244 Determining factors related to poor quality of life in patients with axSpA: results from the British Society for Rheumatology Biologics Register
Notice bibliographique
Résumé
Abstract Background The aim when treating people with axial spondyloarthropathies (axSpA) is to maintain/improve their Quality of Life (QoL), traditionally through reducing disease activity. Previously, the Scotland Registry for Ankylosing Spondylitis (SIRAS) demonstrated, however, that although important, disease activity may not be the only factor influencing QoL. Indeed, function was a better predictor, with fatigue, chronic widespread pain and spinal mobility also important. The aim of the current study was to validate the previous findings in a large nationwide population, and determine if other factors, not collected in the previous study (such as mood and sleep) are also important. Methods The British Society for Rheumatology Biologics Register in Ankylosing Spondylitis (BSRBR-AS) is a prospective cohort of axSpA patients from 83 secondary care centres across Great Britain. Clinical data was collected during routine clinic visits and questionnaires provided patient reported outcomes including: the Ankylosing Spondylitis QoL questionnaire (ASQoL: scored 0 (best) to 18 (worst)), the Bath AS indices for disease & physical activity ((BASDAI/BASFI: scored 0 (best) - 10 (worst)), sleep disturbance (Jenkins: 0 (best) - 20 (worst)), depression (hospital anxiety & depression scales: scored 0 (best) - 21 (worst)) and the modification of the 2010 fibromyalgia criteria (widespread pain index (WPI): scored 0 (best) - 19 (worst) & symptom severity score (SSS): 0 (best) -12 (worst)). Using data collected at BSRBR-AS registration, multivariate linear regression models, predicting ASQoL, were used to validate the previous SIRAS model. Additionally, a de-novo forward stepwise model was developed to assess consistency across both populations and to determine if any additional factors (such as mood and sleep) predicted QoL. Results 1,810 BSRBR-AS participants were eligible for the current study, 67% of whom were male, median age 49 years (interquartile range 38-61). 80% of those tested were HLA-B27 positive and the majority of patients (67%) met the modified New York Criteria for AS. Of the five factors included in the SIRAS model; disease activity, physical function, fatigue and widespread pain remained significantly associated with QoL in the BSRBR-AS study. Spinal mobility was no longer significantly associated. Within the de-novo model eight independent factors predicted ASQoL score: disease activity (coefficient 0.31, 95% (confidence interval 0.14, 0.47)), physical function (0.59 (0.45, 0.73)), depression (HADS: 0.16 (0.09, 0.24)), sleep disturbance (0.08 (0.04, 0.13)), activity impairment (0.04 (0.02, 0.05)), fibromyalgia (SSS: 0.24 (0.13, 0.35), WPI: 0.10 (0.03, 0.17)) and tobacco smoking (vs. non-smoker: 0.66 (0.10, 1.21)). Conclusion Current EULAR guidelines for management of axSpA targeting disease activity and physical function are supported by the current findings which suggest both are consistently important predictors of QoL. However, additional factors such as fatigue, sleep disturbance and mood also contribute to QoL and should be considered additional targets within future axSpA management strategies. Disclosures L.E.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
