AIROLDI, Carla et al. Labor participation in radiographic and non-radiographic axial spondyloarthritis. Rev. argent. reumatolg. [online]. 2021, vol.32, n.4, pp.12-20. ISSN 0327-4411.

Introduction: work disability is an important outcome in the treatment of spondyloarthritis (SpA) since this disease affects people in the most productive stage of life. Objectives: to investigate working status in patients with axial spondyloarthritis (axSpA) from Argentina, including ankylosing spondylitis (AS) and nonradiographic axial SpA (nr-axSpA), and to evaluate factors associated with work productivity loss (WPL) in this national cohort and factors associated with being employed. Materials and methods: patients with a diagnosis of AS and nr-axSpA according to Assessment of SpondyloArthritis international Society (ASAS 2009) classification criteria and in working age (≤65 years) were included in this multicentric cross-sectional study. Outcomes of interest were employment status, absenteeism and presenteeism, assessed by the Work Productivity and Activity Impairment Spondyloarthritis (WPAI-SpA) questionnaire. Spearman's coefficient was used to assess the correlation between disease measures and WPL. Bivariate and multivariate analysis were performed in order to evaluate factors associated with being employed. Results: 129 patients with axSpA were included, 95 (73.6%) with AS and 34 (26.4%) with nr-axSpA. Median (p25-75) age of 45 (35-55) years. Median (p25-75) disease duration was 62 (24-123) months and diagnosis delay was 24 (6-72) months. 60 (46.5%) of the patients were employed. Median (p25-75) presenteeism of AS patients was 29.6% (0-57) and 30% (20-40) for patients with EspAax-nr (p=0.02). Median (p25-75) WPL was 30% in both groups of patients. A positive correlation was found between WPL and the following variables: ASDAS (Rho:0.60), BASDAI (Rho:0.50), BASFI (Rho:0.60), ASQoL (Rho:0.60) and ASAS health index (Rho:0.54). In the bivariate analysis, the factors associated with unemployment were AS diagnosis, older age, longer disease duration, comorbidities (hypertension and diabetes), fewer years of education, worse quality of life and lower functional capacity. In the multivariate analysis, better physical function (assessed by BASFI) was independently associated with being employed. Conclusions: this study showed that WPL in this national cohort was 30% in axSpA. It was associated with disease activity, health status, quality of life and functional capacity. Better physical function was independently associated with a higher likelihood of keeping patients with axSpA employed.
