Pseudo-renal failure

Hawley PC, Ealko JM."Pseudo" renal failure after isopropyl alcohol intoxication. South Med J 1982 75 630-631. 

Pseudo-renal failure occurs when either the blood urea nitrogen (BUN) or creatinine concentration rises suggesting a decrease in renal function, despite maintenance of the GFR. The BUN concentration commonly increases without an increase in creatinine concentration during corticosteroid or tetracycline therapy. These drugs cause protein catabolism and thereby increase ureagenesis and the BUN concentration as the result of tissue breakdown. The GFR is unchanged and accurately reflected by the creatinine clearance and creatinine concentration.
