Observations in patients with growth hormone (GH)-disturbances have suggested that GH/IGF-I might have anti-inflammatory effects. To elucidate this hypothesis the investigators have planned a study to investigate if 3 weeks administration of GH and subsequently the GH antagonist Pegvisomant (or vice versa) influence serum levels of different inflammatory markers in healthy volunteers.

Estimated Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: GH Drug: Somatropin
s.c injections once daily 10-30 mícrogram/kg/day
Active Comparator: Pegvisomant Drug: Pegvisomant

Detailed Description:
To investigate if administration of 3 weeks og GH (10-30 microgram/kg/day) and subsequent Pegvisomant (10-15 mg/day) influence serum concentrations of the inflammatory variables Tumor Necrosis Factor α (TNF-α), Interleukin-6 (IL-6), high sensitive CRP (hsCRP) and the newly discovered acute phase protein YKL-40. The study involves 12 healthy volunteers age from 22-65 years.
