We examined the effect of GH supplementation on the psychological capacity and sense of well-being in 36 patients with adult-onset GH deficiency (GHD). Recombinant human GH was given in a 21-month cross-over, double blind trial, and quality of life was assessed by using three self-rating questionnaires: the Hopkins Symptom Check List (HSCL), the Nottingham Health Profile (NHP), and the Psychological General Well-Being index. In addition, at the final examination the spouses completed a short questionnaire concerning their partner. Before treatment, the patients had lowered quality of life as determined by the HSCL and NHP inventories, and a correlation between the duration of GHD and the reported symptoms was observed. Upon treatment, the HSCL score was lower (better) after placebo administration (mean +/- SD, 84 +/- 21.3) than at baseline (89 +/- 18.9; P = NS) and fell to 80.2 +/- 18.5 (P < 0.001) when active drug was given. The subscales regarding anxiety, fearfulness, and cognition were the most sensitive. It was apparent that the effect determined after GH therapy in part was due to a placebo effect. With NHP, the dimensions of energy and emotions responded most to treatment. Further, the spouses observed their partners to be improved in several aspects of mood and behavior (P < 0.05 to P < 0.0001) when active drug was given. The data thus demonstrate that GH, which is known to have multiple somatic effects, produces an improvement in the quality of life of adults with GHD.

In this study the authors assessed the possible relationship between high dietary exposure to persistent organohalogens (OHS) through fatty fish from the Baltic Sea and hormone levels in adult men. Blood samples were drawn from 110 men who consumed varying amounts of fish (i.e., 0-32 meals per month) for analysis of plasma levels of 18 polychlorinated biphenyl (PCB) congeners, 5 hydroxy-PCBs, 1,1,1-trichloro-2,2-bis(4-chlorophenyl)-ethane (p,p'-DDT), 1,1-dichloro-2,2-bis(4-chlorophenyl)-ethene (p,p'-DDE), hexachlorobenzene, and 2,2',4,4'-tetrabromodiphenyl ether. In addition, plasma levels of follicle-stimulating hormone, luteinizing hormone, prolactin, plasma thyrotropin, free and total T3, free and total T4, and free testosterone were analyzed. The authors adjusted for age, and the only significant associations that remained were negative correlations between 2,2',4,4'-tetrabromodiphenyl ether and plasma thyrotropin (p < .001), and between pentachlorophenol and follicle-stimulating hormone (p = .04). The authors expected that there would be some significant correlations that resulted from pure chance. High consumption of organohalogen-polluted fish did not appear to affect plasma concentrations of pituitary, thyroid, or testosterone hormone levels in male adults.

Context: Craniopharyngioma patients without GH therapy are at an increased cardiovascular disease (CVD) risk and particularly concerning women. No previous study on long-term GH therapy in adults with childhood onset (CO) craniopharyngioma was identified. Objective: To investigate CVD risk in adults with CO craniopharyngioma on complete hormone replacement, including long-term GH therapy, and to investigate the impact of disease-related factors on CVD risk. Design and participants: In a cross-sectional study of operated CO craniopharyngiomas from a defined area of Sweden (2.5 million), we enrolled 42 patients (20 women) with a median age of 28 years (range 17-57) and assessed CVD risk of 20 (4-40) years after first operation. Comparisons were made with matched controls and between patients with tumor growth into the third ventricle (TGTV) versus non-TGTV. GH therapy was 10-12 years in women and men. Results: In comparison with controls, both male and female patients had increased body mass index, fat mass, insulin, and leptin levels. Overall, while not significantly increased in male patients, 55-60% of female patients had a medium-high CVD risk, compared with 10-20% in controls. An increased CVD risk (all P!0.05) and higher levels of fat mass and insulin were recorded in the TGTV group versus the non-TGTV group. Late puberty induction and lack of androgens were shown in female patients. Conclusions: Adult patients with CO craniopharyngioma, especially those with TGTV, have persistently increased CVD risk. Conventional hormone substitution, including GH, is insufficient to normalize CVD risk, suggesting an important role for irreversible hypothalamic dysfunction.

The present study gives some support for the notion that dietary exposure to persistent organochlorine compounds (POCs) might weakly affect peripheral thyroid hormone concentrations in adult women.

In the KIMS database, patients with CP have more often undergone surgery by the transcranial route than patients with NFPA, have a higher prevalence of pituitary deficiencies, are more obese (predominantly males), and have more dyslipidemia. This could provide an explanation, at least in part, for the higher mortality rate in CP patients observed in epidemiological studies. CP patients respond equally well to GH therapy in fat-free mass, lipids, and quality of life, but are less likely to lose body fat. We assume that this difference in response merely reflects the stronger tendency of CP patients to accumulate fat over time.
