EnglishThe aim of these studies was to compare the pharmacokinetics, pharmacodynamics, counterregulatory hormone and symptom responses, as well as cognitive function during hypoglycaemia induced by s.c. injection of 0.15 IU/kg of regular human insulin (HI) and the monomeric insulin analogue [Lys(B28),Pro (B29)] (MI) in insulin-dependent-diabetic (IDDM) subjects. In these studies glucose was infused whenever needed to prevent decreases in plasma glucose below 3 mmol/l. After MI, plasma insulin increased earlier to a peak (60 vs 90 min) which was greater than after HI (294 +/- 24 vs 255 +/- 24 pmol/l), and plasma glucose decreased earlier to a 3 mmol/l plateau (60 vs 120 min) (p < 0.05). The amount of glucose infused to prevent plasma glucose falling below 3 mmol/l was approximately three times greater after MI than HI (293 +/- 26 vs 90 +/- 25 mumol.kg-1 x 60-375 min-1, p < 0.05). After MI, hepatic glucose production was more suppressed (0.7 +/- 1 vs 5.9 +/- 0.54 mumol.kg-1.min-1) and glucose utilization was less suppressed than after HI (11.6 +/- 0.65 vs 9.1 +/- 0.11 mumol.kg-1.min-1) (p < 0.05). Similarly, plasma NEFA, glycerol, and beta-OH-butyrate were more suppressed after MI than HI (p < 0.05), whereas plasma lactate increased only after MI, but not after HI. Responses of counterregulatory hormones, symptoms and deterioration in cognitive function during plasma glucose plateau of 3 mmol/l were superimposable after MI and HI (p = NS).
