Adult growth hormone (GH) deficiency is associated with insulin resistance, elevated cardiovascular risk profile, increased fat mass, reduced muscle mass, skeletal fragility, and impaired quality of life. GH replacement therapy improves body composition, exercise capacity, skeletal health, cardiovascular outcomes, and quality of life, while reducing mortality. Prior to initiation of GH replacement therapy, it is essential to diagnose GH deficiency via a GH stimulation test in adults suspicious of such deficiency. Therapy should be started using (individualized) low dose of GH, followed by titration to the normal range of insulin-like growth factor-1. Clinical improvements should be monitored and side effects should be minimized.

OBJECTIVE: Impaired cognitive function has been demonstrated in adults with growth hormone (GH) deficiency (GHD) by using different neuropsychological tests. Despite several studies, present knowledge about the impact of GHD and GH replacement therapy (GHRT) on cognitive function is limited. P300 event-related potential (ERP) application is a well-established neurophysiological approach in the assessment of cognitive functions including the updating of working memory content and the speed of stimulus evaluation. GHD is a well-known feature of Sheehan's syndrome and cognitive changes due to GHD and the effects of GHRT remain to be clarified. The present study was designed to investigate the effects of GHD and 6 months of GHRT on cognitive function in patients with Sheehan's syndrome by using P300 latency. DESIGN AND METHODS: The study comprised 14 patients with Sheehan's syndrome (mean age, 49.5+/-7.8 years) and 10 age-, education- and sex-matched healthy controls. With hormone replacement therapy, basal hormone levels other than GH were stable before enrollment and throughout the GHRT. The diagnosis of GH deficiency was established by insulin-tolerance test (ITT), and mean peak level of GH in response to insulin hypoglycemia was 0.77+/-0.35 mIU/l. Treatment with GH was started at a dose of 0.45 IU (0.15 mg)/day in month 1, was increased to 0.9 IU (0.30 mg)/day in month 2 and was maintained at 2 IU (0.66 mg)/day. Initially baseline auditory ERPs in patients and controls were recorded at frontal (Fz), central (Cz), and parietal (P3 and P4) electrode sites. In the patient group, ERPs were re-evaluated after 6 months of GH replacement therapy. During each session P300 amplitude and latency were measured. RESULTS: Mean serum insulin-like growth factor-I (IGF-I) concentration in the patient group before GHRT was 23+/-13 ng/ml. After 6 months of GH therapy mean IGF-I significantly increased to an acceptable level, 234+/-71 ng/ml (P<0.05). The mean latencies (at all electrode sites) of the patients before GHRT were found to be significantly prolonged when compared with those of normal controls (P<0.05). After 6 months of GHRT mean P300 latencies (at all electrode sites) were decreased significantly when compared with latencies before treatment (P<0.05). CONCLUSIONS: The present study, using P300 ERP latencies, therefore suggests an impairment of cognitive abilities due to severe GHD in patients with Sheehan's syndrome and an improvement of cognitive function after 6 months of physiological GHRT. Moreover, this was a novel application of P300 ERP latencies in cognitive function detection in patients with GHD. Further studies with different patient groups need to be done to assess the clinical use of this electrophysiological method in the diagnosis of cognitive dysfunction due to GHD.

The consequences of severe growth hormone deficiency (GHD) in adults and the beneficial effects of GH replacement therapy are clear. However, the majority of children who have a diagnosis of GHD and who are treated with GH do not have permanent GHD and will not require treatment during adulthood. Several issues must be considered in selecting candidates for adult GH treatment and transitioning their care from pediatrics to adult medicine. Counseling about possible lifelong treatment should focus on children with panhypopituitarism and those with severe isolated GHD that is associated with central nervous system abnormalities. When to terminate growth-promoting GH therapy should be guided by balancing the high cost of late-adolescent treatment with the attainment of reasonable statural goals. Retesting for GH secretion is appropriate for all candidates for adult GH therapy; the GH axis can be tested within weeks after the cessation of treatment, but confirming an emerging adult GHD state with body composition, blood lipid, and quality-of-life assessments may require 1 year or more of observation. Selecting patients for lifelong adult GH replacement therapy will present diagnostic, therapeutic, and ethical problems similar to those in treating childhood GHD. The experience and expertise of pediatric endocrinologists in diagnosing and treating GHD should be offered and used in identifying and transitioning appropriate patients to adult GH therapy.

Objective: This study set out to determine the change in quality of life (QoL) and healthcare utilization during 2 years of growth hormone (GH) replacement therapy in adults with GH deficiency. Data were compared from three European countries. Design: Analysis was made from KIMS, the Pfizer International Metabolic Database on adult GH deficiency. Methods: QoL and healthcare utilization were measured at baseline and after 1 and 2 years of GH replacement in patient cohorts from Sweden (n = 302), The Netherlands (n = 103) and Germany (n = 98). QoL was assessed by the QoL-Assessment in Growth Hormone Deficient Adults (QoL-AGHDA) questionnaire, and the KIMS Patient Life Situation Form was used to evaluate healthcare utilization. Results: QoL improved significantly (P < 0.0001) and comparably in all three cohorts. The improvement was seen during the first year of treatment and QoL remained improved during the second year. The number of days in hospital was reduced by 83% (P < 0.0001) during GH replacement. There were no country-specific differences either at baseline or during follow-up. The same was true for the number of days of sick leave (reduction of 63%; P = 0.0004). Significant reductions were recorded in the number of doctor visits in each of the three cohorts after 2 years of GH replacement (P < 0.05). Conclusions: This study provides a detailed comparative analysis of GH replacement therapy in GHD patients in three European countries. Despite some differences in treatment strategies, the beneficial effects on QoL, patient-reported outcomes and healthcare utilization are essentially similar in the healthcare environment of Western European countries.

Growth hormone deficiency (GH) for a long time was recognized only in childhood. Compelling evidence has been obtained showing that HR replacement therapy effectively stimulates growth and, in many cases, achieves normal end-points of physical development. More recently, it was shown that the most effective in this regard was the appointment of regular evening injections of the drug, which mimic the physiological secretion of GH during sleep. Despite the fact that the acceleration of linear growth is the most objective criterion for the effectiveness of therapy for GH, it is known that GH has a significant effect on body structure, causing a decrease in fat mass and an increase in muscle mass. Until recently, GH was not considered an important hormonal regulator in adults, and therefore, there was no study of GH deficiency and treatment of children with GH deficiency when they reached adulthood, as well as patients with hypopituitarism who became ill in adulthood. However, in 1989, as a result of two double-blind trials using placebo in the control group, the effectiveness of GH replacement therapy in adults with an abnormally low level of GH, up to a severe degree of GH deficiency, was revealed. Further studies showed the presence of violations of both physical and mental status in adults in whom GH deficiency develops as a result of the tumor process in the pituitary gland or its therapy. Most of these disorders, but not all, can be corrected as a result of GH replacement therapy, which confirms the significant effect of GH throughout life.
