[Long time consequences of the growth hormone deficiency].
This article describes the long time consequences of the isolated and lifetime growth hormone (GH) deficiency using a single model of GH releasing hormone resistance (GHRH) due to a homozygous mutation in the GHRH receptor gene, in a hundred of subjects. These consequences include severe short stature with final height between -9.6 and -5.2 standard deviations below of the mean, with proportional reductions of the bone dimensions; reduction of the anterior pituitary corrected to cranial volume and the thyroid, the uterus, the spleen and left ventricular mass volume, all corrected to body surface, in contrast of pancreas and liver size, bigger than in controls, when equally corrected. Body composition features included marked reduction in the amount of fat free mass (kg) and increase of fat mass percentage, with predominant abdominal deposit. In the metabolic aspects, we find increase in the total cholesterol and LDL cholesterol; reduction of the insulin and the insulin resistance assessed by Homeostasis model assessment; increase of ultra sensitive C reactive protein and systolic body pressure in adults, although without evidences of premature atherosclerosis. Other findings include smaller bone resistance, although above of the threshold of fractures, delayed puberty, normal fertility, small parity, anticipated climacteric and normal quality of life.
