Introduction:
Spondyloarthritis (SpA) is a chronic inflammatory rheumatism most
commonly affecting young men. It is characterized by pelvic-spinal
involvement which may be isolated or associated with peripheral joint
and/or enthesitic involvement and by association with the human
leukocyte antigen B27 (HLA-B27) haplotype (1).
Among the extra-articular manifestations of SpA, renal involvement is
rare and mostly severe . AA amyloidosis, IgA nephropathy and
urolithiasis are the most common causes. However, other nephropathies
could be seen in SpA; they are rare and limited to case reports (2,3).
Thus, we report the case of a focal segmental glomerulosclerosis and
hyalinosis (FSGS) in a patient with axial SpA.
