Abstract

Objectives: This study aimed to assess the predictive factors of functional impairment in spondyloarthritis (SpA) patients assessed with bath ankylosing spondylitis functional index (BASFI) and Lequesne Index (LI).

Methods: This retrospective study was conducted at the Rheumatology Department of Mohamed Kassab Institute of Orthopedics, Manubah, Tunisia, and collected data from 2008 to 2019 over a period of 4 months (August to November 2019). Socio-demographic and disease-related data of SpA patients were collected. Disease activity was assessed using the bath ankylosing spondylitis-global score (BASG-s) and the bath ankylosing spondylitis disease activity index (BASDAI). The spinal mobility was evaluated by the bath ankylosing spondylitis metrology index (BASMI). Structural progression was evaluated with the bath ankylosing spondylitis radiologic index (BASRI) and modified stoke ankylosing spondylitis spine score (mSASSS). A multivariate analysis was done to search for predictive factors associated with BASFI and LI.

Results: A total of 263 patients were included. The mean age was 38.9 ± 12.7 years and the gender ratio was 2.7. The mean age of onset of SpA was 27.6 ± 10.8 years and disease duration was 11.3 ± 9.5 years. Occupation was significantly associated with BASFI and LI scores. A significant functional impact was notably correlated with a long duration of the disease. The two scores were correlated with a limitation of spinal mobility (BASMI), a greater disease activity (BASDAI and erythrocyte sedimentation rate) and a greater impact of the disease on health status (BASG-s). Significant functional impairment was also correlated with structural impairment (mSASSS, BASRI and sacroiliitis grade). The variables independently related to BASFI were the mSASSS score and the BASDAI. The variables independently related to LI were profession (unemployed subjects had higher scores), the mSASSS score and the BASMI.

Conclusion: Occupation, disease activity, mobility and structural progression predicted functional impairment in Tunisian SpA patients.
