Abstract Introduction/Objective The aim of this study was to investigate the effects of GH administration on basic coagulation parameters: PT, aPTT and fibrinogen concentrations in adult GHD patients before and during one year of GH replacement. Methods Twenty-one adult patients with severe GHD (mean age +/- SE: 38.6 +/- 2.8 years) were included in this hospital based, prospective, interventional study. All patients were treated with rhGH for 12 months (GH dose: 0.4 mg/day for male and 0.6 mg/day for female patients). IGF-1 concentrations were determined using RIA-INEP kits. Basic coagulation tests, i.e. aPTT and fibrinogen concentrations, were measured before and after 3, 6 and 12 months of treatment with rhGH. Control values were obtained from fourteen “healthy” subjects matched by age, sex and body mass index (BMI). Results At baseline, we observed no significant differences in PT, aPTT and fibrinogen values between GHD and healthy subjects. IGF-1 concentrations increased significantly within 3 months of GH therapy (8.2 +/- 1.5 vs. 24.2 +/- 2.9 nmol/l, p <0.05) and remained stable thereafter. A significant increase in PT values, which was more pronounced in female subjects, was noted after 6 and 12 months of treatment with GH. aPTT values increased significantly after 12 months of treatment only in male patients (28.8 +/- 4.6 vs. 39.7 +/- 2.1 s.; p <0.05). No significant changes in fibrinogen concentrations were found during the study. Conclusion Twelve months of GH replacement therapy led to a significant increase in PT and aPTT values in adult GHD patients, while fibrinogen concentrations did not change. Changes in PT were more pronounced in female GHD patients, while an increase in aPTT values was observed only in male patients with GHD. The clinical significance of these changes needs further evaluation.

Secondary Rise

The effects of exhausting bicycle exercise at close to maximal work capacity upon circulating levels of hormones and energy substrates in 4 fasting growth-hormone-deficient and 15 fasting healthy subjects (aged 13–18 years) have been studied. As expected, only the healthy subjects showed a rise in plasma growth hormone (GH) levels. In both groups plasma insulin tended to fall, but the decline was more prolonged in the GH-de-ficient group. Plasma Cortisol levels rose in both groups with the exception of one adrenocorticotropin (ACTH)-deficient subject. Blood sugar levels were well-maintained in all but this ACTH-deficient subject, whereas both groups showed marked lactate accumulation. Both groups demonstrated an initial fall and then a secondary rise in serum free fatty acid concentrations; however, fatty acid levels were lower in the GH-deficient group and there was no post-exercise overshoot, suggesting a possible reduction in the effectiveness of lipid mobilization.
