Brief Summary:
The purpose of this study is to compare the cardiovascular risks of growth hormone deficient young adult males who have completed growth hormone therapy to healthy young adult males.

Condition or disease
Growth Hormone Deficiency

Detailed Description:

Adults with growth hormone deficiency are at risk for cardiovascular disease. What age this begins is not known.

The objectives of this study are to compare the following measurements between growth hormone deficient young males 3-7 years post completion of growth hormone treatment and age related healthy controls:

  1. Carotid artery imaging
  2. Metabolic and cardiac parameters
  3. Body composition measurements

Study Type : Observational
Actual Enrollment : 24 participants
Observational Model: Case Control
Time Perspective: Prospective
Official Title: Cardiovascular Risk in Growth Hormone Deficient Young Adult Males After Completing Growth Hormone Therapy.
Study Start Date : June 2008
Primary Completion Date : February 2009
Study Completion Date : February 2009

18-25 year old males, growth hormone deficient, who completed growth hormone treatment 3-5 years prior to enrollment in study
18-25 year old males, healthy, never treated with growth hormones.

Primary Outcome Measures :
  1. Compare carotid artery intima medial thickness [ Time Frame: During study visit ]

Secondary Outcome Measures :
  1. Compare metabolic parameters and body composition measurements [ Time Frame: During study visit ]
