Abstract
Ankylosing spondylitis (AS) can involve the eye, gastrointestinal system, cardiopulmonary system, skin, kidneys, and spinal and peripheral joints. It is rarely accompanied by immunoglobulin A (IgA) nephropathy. Although IgA is involved in both AS and IgA nephropathy, the relationship between these diseases remains unclear. We detected hematuria and proteinuria in a 32-year-old male patient with ankylosing spondylitis that remained stable for 4 years through treatment with etanercept, a tumor necrosis factor-¥á (TNF-¥á) inhibitor, and diagnosed IgA nephropathy through a renal biopsy. IgA nephropathy seems to be less commonly associated with AS disease activity or specific treatment such as TNF-¥á inhibitor use.
