[Intravenous drug use and kidney disease].

Intravenous drug use (IVDU) is a major public health issue, associated with high mortality rates. The risk of overdose, cardiovascular and infectious complications are well known, but IVDU can also lead to different types of kidney disease. Patients can develop acute or chronic kidney injury due to direct nephrotoxicity of the drugs, or present with different types of glomerulonephritis, interstitial nephritis, and bacterial or viral infection-related nephropathy. Diagnosis can be difficult but is essential to prevent irreversible kidney damage. The number of persons with IVDU that develop end-stage kidney disease is increasing and poses challenges for dialysis and transplantation centers. This article summarizes the renal manifestations that clinicians may encounter in persons with IVDU, especially of heroin and cocaine.
