NIETO-RIOS, John Fredy; RUIZ-VELASQUEZ, Luis Miguel; ALVAREZ, Laura  and  SERNA-HIGUITA, Lina María. Acute interstitial nephritis. Literature review. Iatreia [online]. 2020, vol.33, n.2, pp.155-166. ISSN 0121-0793.

Acute tubulointerstitial nephritis is a kidney lesion that mainly affects the interstitium and can lead to a reversible acute kidney injury. It can progress subclinically, with progressive development towards chronic renal failure. Acute tubulointerstitial nephritis has several causes, being the most common medications, herbal products, infections and autoimmune diseases. The main clinical manifestations are polyuria, polaquiuria, nycturia, lumbar pain, microhematuria, leukocyturia, although the patients also can be completely asymptomatic. Treatment is determined by the underlying cause. Steroids play an important role when tubulointerstitial nephritis is caused by medication or autoimmune diseases. The prognosis is usually good if the problem is detected early and treated properly.
