Renal Impairment in Axial Spondyloarthritis: A Prevalent Condition to Consider

Abstract

We read with interest the paper by Couderc, et al1 on the prevalence of renal impairment in patients with spondyloarthritis (SpA) from the ASASCOMOSPA study (Assessment of Spondyloarthritis international Society–COMOrbidities in SPondyloArthritis). Their results encouraged us to investigate renal impairment prevalence in our cohort. Renal impairment [estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2] prevalence in the ASAS-COMOSPA cohort was 5.2% and was associated with age, HLA-B27 positivity, and inflammation in the multivariate analysis. Data are scarce on the prevalence of renal involvement in SpA with evident heterogeneity, ranging from 0.1% to 11.3% of the cases.
