What is interstitial nephritis? Interstitial nephritis (say: in-
ter-stih-shul nef-rye-tus) is a kidney disorder. The kidneys
filter waste and extra fluid from the body. Interstitial
nephritis reduces the kidneys’ ability to filter properly.
Interstitial nephritis is a serious condition, but it can be
treated. However, in rare cases, it may cause kidney failure.
When the kidneys fail, waste and extra fluid build up in the
body and can cause problems with the heart, brain, lungs and
other organs. Diagnosis and Management of Acute Interstitial
Nephritis by CM Kodner, M.D. and A Kudrimoti, M.D. (American
