Acute tubule-interstitial nephritis is a heterogeneous group of inflammatory diseases which affect renal parenchyma and tubules, mostly as a result of the immune-mediated injury. They are the important cause of acute kidney injury accounting for 5-15% of all its causes. In subsequent years, with the development of pharmacotherapy, the incidence of drug-induced nephrotoxicity has been increasing. The other causes of the acute tubule-interstitial nephritis are autoimmune and inflammatory diseases, infections, neoplasms and electrolyte abnormalities. The diagnostics are complex and treatment of the disease is not always easy. The following overview provides a summary of causes of acute tubule-interstitial nephritis, clinical picture of the disease, the diagnosis and treatment.
