AIMS: To investigate the dynamics between plasma and dialysate glucose during HYPOglycemia in children.
STUDY DESIGN: Six children in pre-puberty or early puberty were investigated by multiple blood sampling and micro-dialysis of subcutaneous adipose tissue during a standard arginine-insulin tolerance test.
Glucose and glycerol, as an index of lipolysis, were measured in samples from both compartments. Plasma concentrations of insulin and the main counter-regulatory hormones were also measured.
RESULTS: Plasma and dialysate glucose concentrations were very similar at baseline and increased in concert after infusion of arginine, probably in response to glucagon release.
After insulin injection, glucose in both plasma and dialysate fell in parallel. The subsequent Relative HYPOglycemia Distress [RHOD] response induced a rapid rebound in the plasma concentration with a mean (SD) delay in the dialysate of 16 (3) minutes.
Plasma glycerol was approximately five-fold lower than in the dialysate and did not fluctuate significantly.
Dialysate glycerol decreased with arginine infusion and reached a nadir immediately following insulin administration.
Subsequently, the anti-lipolytic effect of insulin was overcome by the Relative HYPOglycemia Distress [RHOD] response, and lipolysis prevailed in spite of HYPERinsulinemia.
CONCLUSION: Rapid insulin/Relative HYPOglycemia Distress [RHOD] induced rebound of interstitial glucose concentrations is significantly delayed compared with the extraordinarily rapid ... insulin/RHOD induced rebound of blood plasma glucose concentrations, and the anti-lipolytic effect of HYPERinsulinemia is opposed possibly by the glucagonic RHOD response.
