Patient journey, disease burden, and functional disability in patients with axial spondyloarthritis in South Africa: results of International Map of Axial Spondyloarthritis (IMAS)

ObjectiveTo assess the unmet needs of South Africans with axial spondyloarthritis (axSpA) focusing on the patient journey, functional disability, and health-related quality of life.MethodsOne hundred forty-six South African axSpA patients completed the International Map of Axial Spondyloarthritis (IMAS) online survey. Patient journey, functional disability, activities of daily living, and psychological stress were analyzed in relation to socio-demographic characteristics, disease activity, diagnostic delay, extra-musculoskeletal manifestations, and drug therapy.ResultsMajority were female (82.2%) and Caucasian (89.7%) and the mean age of participants, age at onset of initial symptoms, and diagnostic delay were 44.7, 26.7, and 10.8 years, respectively. Participants reported a mean of 3.4 visits to healthcare professionals prior to a definitive diagnosis of axSpA, mostly made by rheumatologists (77.9%). Active disease (BASDAI >= 4) was reported by 87%, 69.9% suffered from psychological distress (general health questionnaire-12 score >= 3), and more than two-thirds suffered functional limitations in daily, personal, and social activities. Multivariable logistic analysis showed that active disease was more common in females [OR (95% CI) = 4.3 (1.2-15.2)] and was associated with greater functional limitation [OR (95% CI) = 1.1 (1.0-1.2)].ConclusionOf all the regions assessed in the IMAS (n = 5557 participants, 27 countries), South Africans reported the longest delay in diagnosis. The South African patient journey depicts a process burdened with diagnostic challenges and delays, coupled with patients experiencing significant personal and social limitations. These results emphasize the urgent need to establish local diagnostic and treatment guidelines for axSpA in South Africa, to reduce diagnostic delay, and to control disease activity associated with functional limitation in axSpA.
