Spondyloarthritis in African Populations Compared to Europeans Living in the United Kingdom

Abstract

Background: With the aim to study Spondyloarthritis in patients originating from Africa and compare the disease with the way it is manifested in Europeans, data was analysed from 62 African patients and compared with 56 Europeans living in the same geographical area (north East London, United Kingdom) and treated under the same health system (NHS). Data analysed were demographic, social and clinical characteristics. Results: Comparisons showed differences in prevalence of psoriasis (more in Caucasians), uveitis (more in Africans), smoking (more in Europeans), and significantly fewer patients of African origin declared family history of SpA. African patients have less disease activity (but not significantly better measured by BASDAI), and statistically significant better functional ability (BASFI) compared to Europeans. No difference has been noted in gender distribution, age of disease onset, disease duration, delay in diagnosis, disease associations with IBD, night pain, or overall wellbeing. Conclusions: SpA is different in Africans in that it shows to be milder in terms of disease activity and functional ability with more uveitis less psoriasis and less family history of SpAs.
