Summary

In a randomized, cross-over study, 20 healthy volunteers will receive a block and replace therapy that mimics physiological GC rhythm (metyrapone plus hydrocortisone) or placebo. Participants will undergo two identical fasting periods with each treatment. With the block and replace therapy, fasting-induced GC peak will be suppressed. Metabolic and autonomic parameters will be compared to reveal whether GCs mediate the physiological adaptions to caloric restriction.

Understanding acute effects of GCs upon caloric restriction is critical, since repetitive disruptions of GC secretion may become harmful in chronic conditions.

Conditions

  • Glucocorticoid Effect

Interventions

DRUG

Metyrapone 250 mg Oral Tablets

During one phase of the study: Metyrapone (pills of 250mg) on empty stomach: Day 1 0-1-1, day 2 1-2-2, day 3 2-3-3 day 4 3-4-4 day 5 4-4-4 day 6 4-4-4 day 7 4-0-0

DRUG

Hydrocortisone 19.9mg s.c., pulsatile with a flow rate of 10μl/s

Hydrocortisone will be delivered subcutaneously via a pump in a pulsed fashion with a flow rate of 10μl/s from day 1 to day 7 in a total daily dose of 19.9mg

DRUG

Placebo 250 mg Tablets

During another phase of the study: identical looking placebo pills starting Day 1 0-1-1, day 2 1-2-2, day 3 2-3-3 day 4 3-4-4 day 5 4-4-4 day 6 4-4-4 day 7 4-0-0

DRUG

Placebo (0,9% NaCl solution)

Placebo (0,9% NaCl solution) 19.9 mg/d subcutaneously via a pump in a pulsed fashion with a flow rate of 10μl/s from day 1 to day 7
