    • Objective: Few studies have determined the effects of more than 5-10 years of GH replacement in adults on body composition and cardiovascular risk factors. Design/patients: In this prospective, single-center, open-label study, the effects of 15 years of GH replacement on body composition and cardiovascular risk factors were determined in 156 hypopituitary adults (93 men) with adult-onset GH deficiency (GHD). Mean age was 50.5 (range 22-74) years at study start. Body composition was measured using dual-energy X-ray absorptiometry. Results: The mean initial GH dose of 0.55 (S. E. M. 0.03) mg/day was gradually lowered to 0.40 (0.01) mg/day after 15 years. The mean serum IGF1 SDS increased from -1.53 (0.10) at baseline to 0.74 (0.13) at study end (P<0.001 vs baseline). Lean soft tissue (LST) increased to 3% above the baseline level at study end (P<0.001). After a 9% decrease during the first year of treatment (P<0.001 vs baseline), body fat (BF) started to increase and had returned to the baseline level after 15 years. Serum levels of total cholesterol and LDL-cholesterol decreased and serum HDL-cholesterol level increased. Fasting plasma glucose increased from 4.4 (0.1) at baseline to 4.8 (0.1) mmol/l at study end (P<0.001). However, blood HbA1c decreased from 5.0 (0.1) to 4.6 (0.1) % (P<0.001). Conclusions: Fifteen-year GH replacement in GHD adults induced a transient decrease in BF and sustained improvements of LST and serum lipid profile. Fasting plasma glucose increased whereas blood HbA1c was reduced. European Journal of Endocrinology 168 745-753

  • Fifteen years of GH replacement increases bone mineral density in hypopituitary patients with adult-onset GH deficiency
  • 2012
  • Ingår i: European Journal of Endocrinology. - : Oxford University Press (OUP). - 0804-4643 .- 1479-683X. ; 166:5, s. 787-795

    • Objective: Few studies have determined the effects of more than 5-10 years of GH replacement in adults on bone mineral content (BMC) and bone mineral density (BMD). Design/patients: In this prospective, single-centre, open-label study, the effects of 15 years of GH replacement on BMC and BMD, measured using dual-energy X-ray absorptiometry, were determined in 126 hypopituitary adults (72 men) with adult-onset GH deficiency (GHD). Mean age was 49.4 (range 22-74) years at the initiation of the study. Results: The mean initial GH dose of 0.63 (S.E.M. 0.03) mg/day was gradually lowered to 0.41 (0.01) mg/day after 15 years. The mean serum IGF1 SDS increased from -1.69 (0.11) at baseline to 0.63 (0.16) at the study end (P < 0.001 vs baseline). The 15 years of GH replacement induced a sustained increase in total body BMC (+5%, P < 0.001) and BMD (+2%, P < 0.001). Lumbar (L2-L4) spine BMC increased by 9% (P < 0.001) and BMD by 5% (P < 0.001). In femur neck, a peak increase in BMC and BMD of 7 and 3%, respectively, was observed after 7 years (both P < 0.001). After 15 years, femur neck BMC was 5% above the baseline value (P < 0.01), whereas femur neck BMD had returned to the baseline level. In most variables, men had a more marked response to GH replacement than women. Conclusions: Fifteen-year GH replacement in GHD adults induced a sustained increase in total body and lumbar (L2-L4) spine BMC and BMD. In femur neck, BMC and BMD peaked at 7 years and then decreased towards baseline values.

  • A 10-year, prospective study of the metabolic effects of growth hormone replacement in adults.
  • 2007
  • Ingår i: The Journal of clinical endocrinology and metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 92:4, s. 1442-5

    • CONTEXT: Only a few studies have investigated the effects of GH replacement in adults for more than 5 yr. OBJECTIVE/DESIGN/PATIENTS: In a prospective, open-label, single-center study, the effects of 10-yr GH replacement were determined. Eighty-seven consecutive patients (52 men and 35 women), with a mean age of 44.1 (range 22-74) yr with adult-onset GH deficiency (GHD) were included. RESULTS: The initial mean dose of GH (0.98 mg/d) was reduced during the study and at yr 10 was 0.47 mg/d. The mean IGF-I sd score increased from -1.81 at baseline to 1.29 at study end. The absolute reduction in total body fat was transient. However, after correction for age and sex using a four-compartment model, the reduction in body fat was sustained during the 10-yr study period. There was a sustained improvement in serum lipid profile and after 10 yr, and blood glycosylated hemoglobin level was reduced. The treatment responses in IGF-I sd score, serum high-density lipoprotein cholesterol level, and body composition as measured using dual-energy x-ray absorptiometry were more marked in men, whereas women had a more marked reduction in blood glycosylated hemoglobin level. CONCLUSION: The effect on the absolute amount of body fat was seen early and was transient, which could be due to the normal aging of the patients. The effects on metabolic indices were detected later, but they were sustained and even progressive throughout the study period.

  • Ten-year GH replacement increases bone mineral density in hypopituitary patients with adult onset GH deficiency.
  • 2007

    • There are few studies that have determined the effects of long-term GH replacement on bone mineral density (BMD) in GH-deficient (GHD) adults. In this study, the effects of 10 years of GH replacement on BMD were assessed in 87 GHD adults using dual energy X-ray absorptiometry (DEXA). The results show that GH replacement induced a sustained increase in BMD at all the skeletal sites measured. INTRODUCTION: Little is known of the effect of more than 5 years of GH replacement therapy on bone metabolism in GHD adults. PATIENTS AND METHODS: In this prospective, open-label, single-center study, which included 87 consecutive adults (52 men and 35 women; mean age of 44.1 (range 22-74) years) with adulthood onset GHD, the effect of 10 years of GH replacement on BMD was determined. RESULTS: The mean initial dose of GH was 0.98 mg/day. The dose was gradually lowered and after 10 years the mean dose was 0.47 mg/day. The mean insulin-like growth factor-I (IGF-I) SDS increased from 1.81 at baseline to 1.29 at study end. The GH replacement induced a sustained increase in total, lumbar (L2-L4) and femur neck BMD, and bone mineral content (BMC) as measured by DEXA. The treatment response in IGF-I SDS was more marked in men, whereas women had a more marked increase in the total body BMC and the total body z-score. There was a tendency for women on estrogen treatment to have a larger increase in bone mass and density compared with women without estrogen replacement. CONCLUSIONS: Ten years of GH replacement in hypopituitary adults induced a sustained, and in some variables even a progressive, increase in bone mass and bone density. The study results also suggest that adequate estrogen replacement is needed in order to have an optimal response in BMD in GHD women.
