Acute interstitial nephritis associated with gentamicin and lincomycin therapy

Area of Science:

• Nephrology
• Pharmacology
• Toxicology

Background:

• Aminoglycoside antibiotics like gentamicin are crucial for treating severe bacterial infections.
• Lincomycin is another antibiotic used for specific bacterial infections.
• Concurrent administration of gentamicin and lincomycin is sometimes employed in clinical practice.

Observation:

• A patient developed acute oliguric renal failure after receiving gentamicin and lincomycin.
• Renal biopsy confirmed acute interstitial nephritis.
• The patient exhibited high serum gentamicin levels and subsequent ototoxicity.

Findings:

• The case demonstrates a direct association between gentamicin and lincomycin treatment and the development of acute interstitial nephritis.
• Elevated gentamicin levels correlated with renal impairment and ototoxicity.
• Cessation of antibiotic therapy and supportive care resulted in swift recovery of kidney function.

Implications:

• Clinicians should be vigilant for potential nephrotoxicity and ototoxicity when prescribing gentamicin and lincomycin concurrently.
• Early recognition and discontinuation of causative antibiotics are critical for managing drug-induced kidney injury.
• This case highlights the importance of therapeutic drug monitoring for gentamicin to prevent adverse events.
