Context: The nadir serum GH level during glucose suppression (OGTT) is recommended in patients treated by surgery, but not during SA treatment. We have shown that patients considered controlled by SA don’t suppress serum GH during OGTT and have impaired disease-specific QoL as compared to patients controlled by surgery. We hypothesize SA treated patients also don’t suppress GH in response to mixed meals.Aim: To compare GH levels during two mixe...

Introduction: Patients with AGHD receiving GH often have comorbidities requiring concomitant treatment. We evaluated patterns of concomitant medication use relative to GH therapy initiation in patients with AGHD.Methods: Patients with AGHD with data on concomitant medications enrolled in NordiNet® IOS (NCT00960128), an international, non-interventional study, receiving GH (Norditropin®, Novo Nordisk A/S, Denmark) therapy w...

Background: GH secretion and action change with age in adult human subjects, and this play an important role in substrate metabolism in aging subjects. Targeted disruption of the GH receptor in mice extends longevity, and this is associated with decreased expression of apoptosis-related genes including caspase-9 (CASP9) in skeletal muscle.Aim: To study DNA methylation of putative GH target genes in skeletal muscle of adult male subjects in relation to bo...

Introduction: Acromegaly is a rare disease caused by GH hypersecretion from a pituitary adenoma. However, accurate estimates of incidence and prevalence are scarce and not based on nationwide populations. It is well known that surgical cure may normalize mortality and improve morbidity but similar data are not available for patients receiving medical treatment.Method: We first validated the ICD-8 and ICD-10 diagnosis codes for acromegaly in The National ...

Background: Current guidelines recommend that susceptible patients should be tested and treated for AGHD. Still, it is not universally recognised as a distinct entity and reimbursement of GH replacement therapy is not available in some countries.Aim: 1) to record current practice of AGHD management throughout Europe and benchmark it against existing guidelines, 2) to evaluate educational status of health care professionals.Patients...

Introduction: Hyponatremia (HN) is the most common electrolyte disorder of hospitalized patients (pts). It occurs in up to 28% of in-pts, increases the in hospital risk of death by 1.47 fold, and is associated with significantly higher mortality risk following discharge. The HN Registry is the first large scale, international effort to document the clinical characteristics, treatments used, and impact of HN in hospital settings.Methods: After informed co...

Introduction: Hyponatremia (serum sodium ≤135 mmol/l), the most common electrolyte disorder encountered, has been associated with increased mortality in patients with particularly cancer, heart failure, chronic kidney and liver disease. However, evidence of the clinical implications in broader populations is scarce, and uncertain due to confounding from preexisting disease. We aimed to examine the association between admission-hyponatremia and 30-day mortality in acute n...

Background: The impact of GH on insulin sensitivity is ambiguous since both long standing GH-deficiency as well as acute GH exposure and prolonged GH-excess are associated with insulin resistance.Aim: To test the hypotheses that the insulin antagonistic effect of GH i) is dynamic and depend on ambient GH levels and ii) subsides gradually with time after GH exposure.Methods: Eight GHDA participated in a randomised crossover study. E...

Context and objective: During fasting growth hormone (GH) promotes lipolysis, attenuates glucose oxidation and preserves protein. Previous studies have primarily been conducted in GH deficient patients or during somatostatin-suppression of GH secretion. We aimed to study the impact of the fasting associated increase in GH without concomitant changes in other hormones, by the means of GH receptor (GHR) blockade.Design: Ten healthy young men participated i...

Background: Fasting is associated with suppression of IGF-I production, which is likely to be the stimulator of GH secretion and the subsequent increase in lipolysis. The GH signalling events subserving this switch in the actions of GH have not been studied.Aim: To assess whole body substrate metabolism and GH signalling proteins in skeletal muscle and fat in healthy human subjects in the postabsorptive state and after 38 h of fasting.<p class="abste...
