Nephrology

ACUTE INTERSTITIAL NEPHRITIS

1. Interstitial disease is caused by inflammation and/or fibrosis of the interstitium.

2. Acute interstitial nephritis (AIN) is caused by drug-induced hypersensitivity reaction.

3. Implicated drugs include: NSAIDs, PPI, cimetidine, thia­zides, allopurinol and antibiotics (beta-lactams, TMP)

4. NSAID-induced AIN typically causes nephrotic-range proteinuria and glomer­ular changes consistent with those of minimal change disease.

5. Other causes - sarcoidosis, SLE, Sjogren's, transplant rejection, and infection (e.g., pyelo, Legionella, streptococci).
