Acute tubulointerstitial nephritis, treatment with steroid and impact on renal outcomes.

Background: The use and timing of steroids in the management of acute tubulointerstitial nephritis (ATIN) remains debatable.

Aims: To determine the incidence and aetiology of ATIN in our unit, and to examine trends in the use of steroids and their impact on renal outcomes.

Methods: Patients with a histological diagnosis of ATIN over a 9-year period were identified and divided into steroid-treated (StG) and steroid-naïve groups (SnG).
