Clinical manifestations of adult tubulointerstitial nephritis and uveitis (TINU) syndrome Academic Article uri icon

abstract

  • To describe the clinical manifestations and response to therapy of adult patients with tubulointerstitial nephritis and uveitis (TINU) syndrome and to provide suggested work-up and treatment. We retrospectively examined medical records of all adult patients suffering from TINU at Soroka University Medical Center (SUMC) over the past 15 years. Characteristics of ocular and nephrologic manifestations were investigated with particular attention given to age, presenting signs and symptoms, treatment and course of disease. Five adult patients (median age 44 years) were diagnosed with TINU syndrome and followed from 1991-2006 at SUMC. As renal involvement was present at initial evaluation in all patients, they were all treated with steroids. They all suffered from moderate to severe ocular inflammation and most of them relapsed; they also suffered from TINU-related non-specific symptoms. The uveitis in our adult patients was more severe than previously reported. Renal failure and TINU-related non-specific symptoms were observed in all patients and led to the diagnosis of TINU and to systemic therapy which is more aggressive than the usual therapy for uvetis. Thus, early suspicion and diagnosis of TINU may help to direct the appropriate therapy for the degree of uveitis observed in these patients.
