• Nonacetylated salicylates have not been reported to cause the hemodynamically mediated acute renal failure associated with nonsteroidal anti-inflammatory drug therapy. A 73-year-old woman with a creatinine clearance of 0.33 mL/s (20 mL/min), hypertension, and arterioscleroticcardiovascular disease developed reversible renal insufficiency when her dose of salsalate was increased to 4.5 g/d (serum salicylate concentration, 2.22 mmol/L [30.7 mg/dL]). Under close observation the patient was re-treated with lower doses of salsalate while renal function and the urinary excretions of prostaglandins were monitored. The excretion of prostaglandin E2 decreased abruptly while the excretion of 6-keto-prostaglandin F decreased more gradually as the dose of salsalate was increased. Renal function appeared to decline in parallel with the decrease in 6-keto-prostaglandin F and recovered rapidly after discontinuation of salsalate therapy. Nonacetylated salicylates can cause a hemodynamically mediated acute renal failure in patients at risk for this nephropathy.
