Cocaine Hurts Your Kidneys Too: A Rare Case of Acute Interstitial Nephritis Caused by Cocaine Abuse.

Cocaine is a powerfully addictive recreational drug that is extracted from the leaves of the Erythroxylon coca plant native to Central and South America. It is a widely abused substance, despite being banned since the early 19th century due to fatalities. Cocaine may result in acute kidney injury (AKI) by different mechanisms, but acute interstitial nephritis (AIN) is scarcely recognized as the cause of acute kidney injury (AKI). Here, we present a case of AKI from both AIN and acute tubular necrosis (ATN) following cocaine insufflation. The purpose of this article is to review the rare but significant association of AIN associated with cocaine use. The nature of the treatment of cocaine-related kidney disease may differ from other causes of acute kidney insult. Prompt recognition of the underlying cause of renal dysfunction is vital for this group of patients to prevent the rapid deterioration of renal function.
