About

The primary aim of the present study is to study the effect of adrenaline administration on inflammatory parameters (e.g. leukocyte phenotype, cytokines, inflammatory proteins). Secondary objectives consist of the effect of adrenaline on atherogenic parameters.

• All participants will receive intravenous infusion of adrenaline for an hour
• We will draw blood at 7 time points, not including screening
• Participants will be asked to return for a total of 4 times

Researchers will compare 2 groups, healthy individuals versus people with diabetes type 1 to see if the inflammatory reaction to adrenaline differs between these two groups.

Full description

Objective: The aim of the present study is to study the effect of increased adrenaline levels on the inflammatory response (e.g. leukocyte phenotype, cytokines, inflammatory proteins) by administering exogenous adrenaline in participants with type 1 diabetes and healthy participants.

Potentially eligible adult ( 16 - 75 years) participants will be recruited from the diabetes clinic at the department of internal medicine from the Radboud University Medical Center. Healthy participants will be recruited through social media and other advertisements. We will recruit a total of 30 individuals, i.e. 15 healthy participants and 15 people with type 1 diabetes. Participants with type 1 diabetes will be equipped with a blinded continuous glucose monitoring device (CGM) during the test, which will measure interstitial glucose levels for a total of 10 days.

Intervention: All participants will receive intravenous infusion of adrenaline at a rate of 0.04ug/kg/min for 1 hour. We will draw blood at baseline, 30 minutes, 60 minutes, 180 minutes, 24 hours 72 hours and a week after start of infusion. The blood samples will be used for phenotyping of the innate immune system and measuring inflammatory and atherogenic parameters. Throughout the infusion, vital parameters will be monitored.

Enrollment: 30 patients
