Renal manifestations of spondyloarthritis are rare. The case is presented of a patient with ankylosing spondylitis of nine years of evolution. He had intense inflammation, as well as articular sequelae, with a significant deterioration in his quality of life. At the initial evaluation, the patient had a serum creatinine of 1.44mg/dL and a 24-h urine protein in the sub-nephrotic range (1.44 g). Renal biopsy showed the presence of Congophilic material, confirming the diagnosis of AA amyloidosis. Treatment with a TNF blocking agent was initiated with clinical improvement, especially regarding articular disease.
