Study information
Scientific title
Acronym
FHBL
Study hypothesis
Patients with familial hypobetalipoproteinemia (FHBL) could have increased hepatic glucose production because of hepatic steatosis. In addition, peripheral insulin sensitivity could be enhanced since these patients have lower concentrations of intramyocellular lipids.

Patient information sheet
Condition
Familial hypobetalipoproteinemia (FHBL), hepatic steatosis
Intervention
A hyperinsulinaemic clamp will be performed for 4.5 hours
using stabile isotopes (d2-glucose and D5-glycerol). In addition, muscle
biopsies will be taken and fat distribution will be studied by a dual energy x-ray absorptiometry (DEXA)-scan, a
computed tomography (CT)-scan and magnetic resonance spectroscopy (MRS). Patients with FHBL will be compared to healthy
controls matched for age,sex, BMI and waist circumference.
