Successful Treatment of Secondary Renal Amyloidosis With Sairei-to in Rheumatoid Arthritis / 日本東洋医学雑誌

The authors report a case of secondary renal amyloidosis associated with rheumatoid arthritis, which responded well to Kampo therapy. A 68-year-old woman was diagnosed as having rheumatoid arthritis in April 1992. Her disease activity was not controlled well with any anti-rheumatic drugs. In September 1996, proteinuria and hematuria were found, and a renal biopsy showed secondary amyloidosis. Proteinuria and hematuria were progressive. The patient was treated with Sairei-to, and by April 1998, proteinuria and hematuria nearly disappeared. This clinical course suggests that Sairei-to is an effective treatment for secondary renal amyloidosis.
