  • Title: [Role of insulin and counter-regulatory hormones in the metabolic changes caused by insulin deprivation in diabetic patients].
    Author: Castillo MJ, Scheen AJ, Gualda P, Lefebvre PJ.
    Journal: Rev Esp Fisiol; 1989 Mar; 45(1):53-9. PubMed ID: 2664924.
    Abstract:
    In eight insulin dependent diabetic patients treated by continuous subcutaneous insulin infusion (1.1 +/- 0.2 U/h), the levels (measured hourly from 23 h to 05 h) of blood glucose, non esterified fatty acids (NEFA), glycerol and 3-OH-butyrate (3-OH-B) have been correlated to the circulating levels of free insulin (FIRI), glucagon, growth hormone or cortisol, in two experimental conditions: A. Insulin being infused as usual (physiological FIRI levels) and B. Progressively declining FIRI levels (insulin infusion arrested at 23 h). In condition A, blood glucose levels correlated significantly to both insulin and glucagon; NEFA, glycerol and 3OH-B correlated only to insulin. In condition B, blood glucose was significantly correlated to insulin but not to glucagon while NEFA, glycerol and 3-OH-B were significantly correlated to both hormones but not to growth hormone or cortisol. Therefore, on the metabolic deterioration that follows insulin withdrawal, growth hormone and cortisol seem to play a minor role, the main role being played by the decrease in circulating insulin levels and to a lesser extent by the increase in glucagon levels.
