title: Growth hormone does not affect albumin synthesis in the critically ill.
abstract: OBJECTIVE
  To study the effect of growth hormone (GH) on albumin synthesis in critically ill patients.
  
  
  METHODS
  Prospective randomized controlled study.
  
  
  METHODS
  Two intensive care units, university hospital and county hospital, respectively.
  
  
  METHODS
  Twenty-two critically ill patients in the intensive care unit.
  
  
  METHODS
  Albumin synthesis was measured twice in each patient, with a 5-day interval. The patients in the control group (n = 11) received standard intensive care unit (ICU) treatment between measurements, whereas those in the GH group (n = 11) also received 0.3 U/kg daily of human recombinant GH.
  
  
  RESULTS
  Albumin synthesis was measured by labeling with L-[2H5]phenylalanine. In the control group, the fractional synthesis rate (FSR) of albumin was 16.3+/-4.1%/day (mean and SD) in the first measurement and 15.7+/-4.2%/day 5 days later (NS), whereas in the GH group the corresponding values were 17.0+/-4.7%/day and 16.7+/-5.5%/day (NS). The calculated absolute synthesis rates of albumin, based on FSR and intravascular albumin mass, also showed no effect of GH.
  
  
  CONCLUSIONS
  Albumin synthesis rates were consistently higher in the two groups of critically ill patients than previously reported values in healthy subjects. However, GH treatment for 5 days neither stimulated nor inhibited albumin synthesis rates in these critically ill patients.
