Long term follow up of hypopituitary patients treated with human growth hormone

: Thirty-six former human growth hormone (hGH) recipients underwent comprehensive physical, endocrine and lipoprotein evaluations as adults. Treatment was associated with a decrease in height standard deviation score (SDS) in males from 4.0 pretreatment to 2.1 as adults, and in females from 4.2 to 2.5. Males showed a better growth response to treatment than did females. Plasma somatomedin-C levels were subnormal in 30 patients, but were higher in isolated growth-hormone-deficient patients than in others. Three men and 1 woman showed evidence suggesting a disturbance in pulsatile gonadotropin release despite the previous documentation of normal serum gonadotropin levels. Hypertriglyceridemia was not observed, and the women's plasma cholesterol levels were unremarkable. Men, however, showed higher-than-expected total cholesterol, LDL-cholesterol, and HDL-cholesterol concentrations. The last finding may explain the lack of increased cardiovascular morbidity in this group.
