Splanchnic and renal metabolism of insulin in human subjects: a dose-response study

Kinetic analyses of insulin metabolism were performed in 32 healthy subjects with hepatic-venous or renal-venous catheters, in whom steady-state conditions of hyperinsulinemia or hyperglycemia were achieved with the use of the glucose-insulin clamp technique

Scholarcy highlights

  • Kinetic analyses of insulin metabolism were performed in 32 healthy subjects with hepatic-venous or renal-venous catheters, in whom steady-state conditions of hyperinsulinemia or hyperglycemia were achieved with the use of the glucose-insulin clamp technique
  • A) both splanchnic and renal insulin removal are independent of glycemia and increase in proportion to plasma insulin concentration within the physiological range; b) splanchnic uptake is the dominant mechanism of removal of insulin from the circulation whether the route of delivery is portal or peripheral; and c) the kidneys account for the greater part of extrasplanchnic insulin metabolism
