Abstract
|
|
|
|
Secondary amyloidosis is a severe complication of refractory rheumatoid arthritis for which no effective treatment exists. Although the benefits of tumor necrosis factor alpha inhibitors in rheumatoid arthritis treatment are well known, their role in renal amyloidosis secondary to rheumatoid arthritis is unclear and their safety in patients with chronic kidney disease is not well reported. We present an unusual case of a 65-year-old female with moderate renal failure and severe proteinuria, who was diagnosed with secondary amyloidosis associated with refractory rheumatoid arthritis subsequent to treatment with corticosteroids, methotrexate, hydroxychlorquine, and leflunomide. She was treated with etanercept 25 mg, administered as a subcutaneous injection twice weekly for 8 months. The patient had no complications following the treatment. Treatment with etanercept led to a decrease in proteinuria and stabilization of renal function over time.
