Secondary Amyloidosis Associated with Multiple Sclerosis

초록

Background Multiple sclerosis (MS) is a demyelinating disease of the central nervous system. Secondary amyloidosis can occur as a complication of chronic systemic inflammatory and infectious diseases. Until now there has been no report of secondary amyloidosis associated with MS. We report herein a case of renal biopsy-proven secondary amyloidosis in a patient with MS. Case Report A 41-year-old woman with MS was hospitalized due to aggravated quadriparesis and edema in both lower extremities. Laboratory findings showed nephrotic-range proteinuria and hypoalbuminemia. A percutaneous renal biopsy procedure was performed, the results of which revealed secondary amyloid-A-type amyloidosis associated with MS. Conclusions This is the first report of secondary amyloidosis associated with MS.
