Tubulointerstitial nephritis and uveitis syndrome: Our experience

Abstract

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a distinct oculorenal disorder of immune origin and accounts for some cases of unexplained recurrent uveitis. We report three cases of TINU syndrome, one of which had primarily come to us with uveitis. It is the occurrence of tubulointerstitial nephritis and uveitis in a patient in the absence of other systemic diseases that can cause either interstitial nephritis or uveitis. TINU syndrome is a diagnosis of exclusion. Our aim in reporting these cases is to highlight the association of nephritis and uveitis, which together form a distinct clinical disorder called the TINU syndrome.
