Description
Summary:BackgroundDuring its course, spondyloarthritis (SpA) may be associated with extra-articular manifestations affecting several organs. Renal involvement is one of the most common extra-articular manifestations and is dominated by secondary amyloidosis (AA), immunoglobulin A (IgA) nephropathy, and urolithiasis. Other nephropathies such as Focal segmental glomerulosclerosis and hyalinosis (FSGS) are less common and are limited to few case reports. CaseWe report the case of a patient followed for axial SpA, who consulted, after being lost to follow-up for 3 years, for elevated blood pressure and edema of both lower limbs associated with an hydrocele and bilateral pleural effusion. Biological examinations showed hypoproteinemia, hypoalbuminemia, and proteinuria. In this context of nephrotic syndrome, the diagnosis of FSGS was confirmed by renal biopsy. Furthermore, the etiological investigation ruled out the causes of secondary FSGS. ConclusionRenal involvement is a sign of severity in SpA. Its detection and management should be part of the overall management of SpA.
