A Rare Case of Acute Renal Failure Due to Tubulointerstitial Nephritis and Uveitis Syndrome Successfully Treated With Steroid

Abstract

We hereby describe a 49-year-old woman with acute renal failure due to tubulointerstitial nephritis and uveitis (TINU) syndrome. This patient presented with vomiting and nausea and was found to have chronic uveitis, elevated creatinine, and interstitial nephritis. The combination of tubulointerstitial nephritis and uveitis emerged the diagnosis of TINU syndrome after a stepwise examination for differential diagnosis. Clinical course and renal function improved quickly on oral steroids but not to normal range. TINU syndrome, although known to some ophthalmologists and nephrologists, is still rather obscure. TINU syndrome should be considered in patients with uveitis in combination with acute renal failure. The prognosis for the renal disorder is excellent, although the uveitis often recurs or remains chronic.
