title: Nabumetone-associated interstitial nephritis.
abstract: An 84-year-old woman was admitted to the hospital for progressive edema and decreased urine output. She had been taking nabumetone for 6 months, but had discontinued the agent 2 weeks before admission due to progressive edema. On admission she had 2-3+ pitting edema. Her serum electrolytes were sodium 122 mEq/L, potassium 5.9 mEq/L, chloride 93 mEq/L, and carbon dioxide 19 mEq/L. A urinalysis was significant for protein 3061 mg/dl, ketones 15 mg/dl, blood 2+, leukocytes 26-50/high-power field, and a protein:creatinine ratio 24.9. The serum creatinine and blood urea nitrogen concentrations were 2.7 mg/dl and 70 mg/dl, respectively. Throughout hospitalization the patient underwent aggressive diuresis. She developed congestive heart failure, and hemodialysis was initiated. A renal biopsy specimen on hospital day 9 showed tubular damage with minimal glomerular changes consistent with a diagnosis of nonsteroidal agent-induced nephropathy. On day 13, a 24-hour urine collection had a protein excretion of 3151 mg. Although the patient recovered from her renal failure (creatinine clearance 43 ml/min), the nephrotic syndrome persisted (13 g protein/day). The patient developed infectious complications and died on hospital day 32.
