Nutritional and hormonal effects of biosynthetic human growth hormone in surgical patients on total parenteral nutrition.
The anabolic effects of biosynthetic human growth hormone (BHGH) were tested on 30 patients, aged 37-68 yr, divided into four groups: group 1 received surgery plus total parenteral nutrition (TPN) plus BHGH, group 2 received just surgery and TPN, Group 3 received TPN and BHGH, and group 4 received just TPN. TPN was given as an all-in-one formula (glucose 4.7 g.kg.-1day-1, amino acids 1.2 g.kg-1.day-1, lipids 0.7 g.kg-1.day-1, electrolytes and trace elements. BHGH (0.25 IU.kg-1.day-1) or placebo were administered subcutaneously at 0800 for 10 days. Nitrogen and phosphorous balance, as well as the common plasma nutritional markers (transferrin, albumin, prealbumin), triglycerides, apolipoprotein B, insulin, and cortisol were evaluated daily. Urinary creatinine loss was evaluated on days 3, 7, and 10. Cumulative nitrogen balance was better in group 1 (-16.1 +/- 3.2 g N2) than in group 2 (-33.7 +/- 4.6 g N2) (P less than 0.01), whereas the difference was nonsignificant in groups 3 and 4. Phosphorous balance and creatinine excretion paralleled nitrogen balance. Plasma markers were not significantly improved in group 1 compared with group 2; however, they were significantly better in group 3 than in group 4. Lipids were better metabolized in the BHGH-treated groups. Insulin was increased in both groups 1 and 3, whereas cortisol did not rise after surgical stress, probably because of BHGH administration. A positive effect of BHGH on nutritional status and hormonal background is suggested by these data.
