title: Urinary excretion of vitamin A in critically ill patients complicated with acute renal failure.
abstract: OBJECTIVE
  Study the possible excretion of vitamin A in urine of critically ill patients complicated with acute renal failure.
  
  
  METHODS
  Nine Intensive Care Unit patients, age 71.2 +/- 15.7 (mean +/- SD) with acute renal failure were studied. Urinary retinol, creatinine, protein, albumin, and serum creatinine were measured.
  
  
  RESULTS
  All patients excreted retinol in urine; individual values ranged from 0.007 to 0.379 micromol retinol/mmol creatinine. There was no correlation of urinary retinol/creatinine ratio with serum creatinine or with urinary protein/creatinine and albumin/creatinine ratios.
  
  
  CONCLUSIONS
  Excretion of retinol in urine may be indicative of acute renal failure in critically ill patients.
