The Relationship Between the Growth Hormone (GH)- Insulin Like Growth Factor I (IGF-I) System and the Inflammatory System in Healthy Normal Persons

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.

Primary Outcome Measures:
  • The relationship between changes in serum levels of Tumor Necrosis Factor α (TNF-α), Interleukin-6 (IL-6), high sensitive CRP (hsCRP) and YKL-40 vs. changes in serum levels og IGF-I [ Time Frame: 1/9 2009 - 1/3 2010 ]

Estimated Enrollment: 12
Study Start Date: September 2009
Estimated Study Completion Date: March 2010
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
s.c. injections once daily (10-15 mg/day)

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.
