Tubulointerstitial nephritis and uveitis syndrome in children: What to keep an eye on

Due to its heterogeneity in clinical presentation, all paediatric patients presenting with unilateral or bilateral uveitis should be screened for TINU. Likewise, patients who present with tubulointerstitial nephritis should be screened for the development of uveitis within the first several months. Ophthalmological outcome is favourable after long-term treatment with immunosuppressive medications. Finally, identifying tubulointerstitial nephritis early is important, as nearly one-third of cases can develop CKD and may therefore benefit from early treatment with corticosteroids.
