Health Condition(s) or Problem(s) studied

Patients with adult-onset growth hormone deficiency and the presence of atherosclerotic disease in the coronary arteries

Intervention(s)

Trade Name: Genotropin
Product Name: genotropin
Product Code: RVG 15790 or RVG 25480
Pharmaceutical Form: Concentrate for solution for injection

Primary Outcome(s)

Main Objective: Hypothesis:

1. Patients who suffer from a hypopituitarism and an adult-onset growth hormone deficiency (AGHD) express more atherosclerotic disease in the coronary system (compared with a historically formed control subjects, present as a database in the cardiology department from the UMC Utrecht)
2. Atherosclerotic disease in the coronary system wil be in regression after one year substitution with recombinant human growth hormone (in line with previously published results with regard to carotid IMT)

Primary end point(s): 1. Presence of atherosclerotic disease in the coronary system (scored in an established (blinded) protocol as the level of stenosis within coronary segments and the level of intracoronary calcium)

Secondary Objective: Patients with a hypopituitarism and AGHD display additional proatherogenic mechanisms: 2.1 disturbances in antioxidant capacity of the high-density lipoprotein (HDL) fraction, 2.2 disturbances in the differentiation of endothelial progenitor cells with a less capacity to repair damaged endothelium, 2.3 an increase of metalloproteinases as part of the pro-inflammatory profile in circulation .
