SILVA, Filipa et al. Acute tubulointersticial nephritis with uveitis: A report of two cases. Port J Nephrol Hypert [online]. 2018, vol.32, n.2, pp.191-195. ISSN 0872-0169.

Tubulointersticial nephritis and uveitis syndrome is an idiopathic and rare cause of acute kidney injury that should not overlooked, because it usually requires specific therapeutic interventions. We report two distinct cases: a young and an elder female. Both cases presented with unspecific constitutional symptoms but had different onset of renal and ocular involvement. Both were treated with topical and systemic corticoids and although there was a good initial response in both cases, an early relapse after steroids taper was observed in the younger patient and a persistent renal dysfunction in the older one. A high clinical suspicion and understanding of this disease is necessary for an adequate management and treatment of these patients. Recent data associates a worse renal prognosis when the disease appears inadvanced age. In both of our cases the outcome was good but we had a short follow-up. The histological presentation of this disease in our older patient was similar to that reported in the literature, with a high percentage of fibrosis and chronicity of renal tissue that can contribute to the higher grade of renal dysfunction in this type of patients
