Description
Summary:Tubulointerstitial nephritis and uveitis syndrome (TINU) is a rare autoimmune disease. It is characterized by uveitis and kidney damage. The presentation of uveitis is typically anterior and bilateral, while the renal lesion is an acute interstitial nephritis. We report a case of an adolescent diagnosed with this disease, who presented with ocular and constitutional symptoms. An ophthalmologic examination confirmed the diagnosis of uveitis, and subsequent systemic evaluation revealed impaired renal function. The findings of the renal biopsy established the diagnosis after ruling out other systemic diseases. Given the rarity and nonspecific clinical presentation of this condition, a high level of suspicion is required for early diagnosis and treatment. Clinicians should consider this diagnosis in a pediatric patient with uveitis and impaired renal function.Tubulointerstitial nephritis and uveitis syndrome (TINU) is a rare autoimmune disease.
