Drug-induced renal failure: a focus on tubulointerstitial disease

Area of Science:

• Nephrology
• Pharmacology
• Toxicology

Background:

• Therapeutic agents are a common cause of acute renal failure (ARF).
• Drug-induced kidney injury manifests in diverse patterns, primarily affecting the tubulointerstitium.
• Understanding these patterns is crucial for accurate diagnosis and management.

Purpose of the Study:

• To review the various patterns of drug-induced renal failure.
• To focus specifically on tubulointerstitial disease patterns caused by medications.
• To elucidate the mechanisms of acute interstitial nephritis (AIN) and acute tubular necrosis (ATN).

Main Methods:

• Literature review of studies on drug-induced renal injury.
• Analysis of mechanisms leading to tubulointerstitial disease.
• Categorization of renal injury patterns based on underlying pathology.

Main Results:

• Acute interstitial nephritis (AIN) results from allergic reactions to medications, causing inflammation and tubular damage.
• Acute tubular necrosis (ATN) is a direct toxic effect on tubular epithelia, typically without inflammation.
• Other less common patterns include osmotic nephropathy, crystal nephropathy, and acute nephrocalcinosis.

Conclusions:

• Drug-induced renal failure encompasses multiple injury patterns, with tubulointerstitial disease being prominent.
• AIN and ATN represent distinct mechanisms of drug-induced kidney damage.
• This review highlights the importance of recognizing diverse drug-induced nephropathies for effective patient care.
