Polymyalgia rheumatica in a patient with acute tubulointerstitial nephritis due to Sjogren's syndrome

Abstract

A 68-year-old Japanese woman with polymyalgia rheumatica associated with acute tubulointerstitial nephritis and subclinical Sjogren's syndrome is described. Gallium scintigraphy showed marked accumulation in both kidneys and the salivary glands. Renal biopsy revealed lymphocytic infiltration in the tubulointerstitium. She was treated with intravenous high-dose methylprednisolone followed by oral prednisolone. Her clinical symptoms improved. This is the first report of this particular association.
