Key result
Severe hypoglycemia induced during neurohumoral counterregulatory blockade resulted in nearly twice the hepatic glucose production (1.05 mg/kg per min) compared to complete counterregulatory blockade (0.58 mg/kg per min), demonstrating that hepatic autoregulation acts as an emergency defense mechanism.
Why the study?
Does hepatic autoregulation play a role in defense against severe hypoglycemia in humans?

Absolute Event Rate: 1.05% vs 0.58%
p-value: p=<0.01
Hepatic autoregulation serves as an emergency system to augment glucose production during severe hypoglycemia when neurohumoral counterregulation fails.

Supports hepatic autoregulation as hypoglycemia backup when counterregulation fails; leaves open clinical relevance in at-risk patients.
Bolli et al. (1985) studied Healthy volunteers (induced hypoglycemia) (n=12). Severe hypoglycemia during neurohumoral counterregulatory blockade vs. Complete counterregulatory blockade was evaluated on Hepatic glucose production at 9 hours (p=<0.01). Severe hypoglycemia induced during neurohumoral counterregulatory blockade resulted in nearly twice the hepatic glucose production (1.05 mg/kg per min) compared to complete counterregulatory blockade (0.58 mg/kg per min), demonstrating that hepatic autoregulation acts as an emergency defense mechanism.
