[Role of anabolic hormonal factors in surgery in adults].
Hormonal agents with anabolic effect are virtually able to limit or even to counteract the adverse effects of stress and to act in synergy with nutritional support. Hormones with a high theoretic anabolic power include recombinant human growth hormone (rGH), insulin, insulin-like growth factor and testosterone. Other molecules favour anabolism in modifying the catabolic effect of diseases (anti-cytokines, beta-adrenoceptor agonists), in promoting intestinal absorption of substrates or in stimulating epithelial growth (EGF). The results of preliminary studies cannot be transferred into routine clinical practice. The rGH favours the preservation of body mass integrity and various functions. Therefore it could improve postoperative outcome and decrease the duration of hospital stay. A study in severely burnt children showed the metabolic benefits of rGH as well as a shortening of hospital stay because of a decrease of cicatrisation delay after skin grafting. Finally it demonstrated that rGH allows major financial savings in severe burns. The IGF-1 stimulates host defences and decreases the rate of wound infections. The rGH potentiates nitrogen sparing effect of IGF-1 and decreases hypoglycaemia induced by IGF-1. However a study on patients in stress is yet lacking. A combination of growth factors could be virtually efficient, however the cost seems exorbitant. An unquestionable evidence of their clinical efficiency is required before a clinical use in routine can be considered. The postoperative protein catabolism could be decreased by nandrolone decanoate or its derivatives. On the other hand, it has not been proven that protein synthesis, the muscle function or clinical prognosis can be improved by such a treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
