Biochemical assessment of disease control in acromegaly: reappraisal of the glucose suppression test in somatostatin analogue (SA) treated patients

Arlien-Soborg Mai C. , Alvarson Elin , Dal Jakob , Jorgensen Jens Otto L.

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...

Concomitant medication in growth hormone (GH)-treated patients with adult GH deficiency (AGHD): an analysis from NordiNet® International Outcome Study (IOS)

Hoybye Charlotte , Pournara Effie , Pedersen Birgitte Tonnes , Jorgensen Jens Otto Lunde

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...

The metabolic relevance of angiopoietin-like protein 4 in different states of GH/IGF1 excess or deficiency

Olarescu Nicoleta Cristina , Jorgensen Anders P , Heck Ansgar , Normann Kjersti R , Godang Kristin , Bollerslev Jens

Context: Angiopoietin-like protein 4 (Angptl4) is a protein involved in lipolysis, that is regulated by non-esterified free fatty acids (FFA). GH promotes lipolysis and increases circulating FFA. Hypothesis: GH increases circulating Angptl4 levels by modulating its expression and secretion from fat and muscle. Angptl4 might be of metabolic relevance for the insulin resistance associated with GH/IGF1 excess or deficiency.Objective: To evaluate Angptl4 in ...

Epigenetic regulation of GH target genes and its relation to in vivo GH signaling in skeletal muscle of adult human males: a pilot study

Pedersen Morten H , Vestergaard Poul F , Switnicki Michal , Jessen Niels , Jorgensen Jens O L

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...

Incidence and late prognosis of acromegaly in Denmark: preliminary data

Dal Jakob , Feldt-Rasmussen Ulla , Andersen Marianne , Kristensen Lars , Laurberg Peter , Sorensen Henrik , Jorgensen Jens Otto

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 ...

Liraglutide, a glucagon-like peptide-1 receptor agonist, improves bone mass and architecture in ovariectomised mice

Pereira Marie , Jeyabalan Jeshmi , Jorgensen Camilla Sofie , Cleasby Mark , Hopkinson Mark , Chenu Chantal

The increased incidence of type 2 diabetes mellitus (T2DM) among the aged is associated with an impaired skeletal structure and a higher prevalence for bone fractures. Besides, anti-diabetic therapies can also negatively affect bone mass. In this study, we tested the skeletal effects of chronic administration of two glucagon-like peptide receptor (GLP-1R) agonists and examined the expression of GLP-1R in bone tissue and cells. Twelve week-old female C57Bl/6N mice were ovariect...

European Society of Endocrinology audit and multi-country comparison of Adult Growth Hormone Deficiency (AGHD) treatment in clinical practice in Europe and Australia; –how closely are protocols and best practice recommendations followed

Martel-Duguech Luciana , Screen Nik , Jorgensen Jens Otto L , Korbonits Marta , Johannsson Gudmundur , Webb Susan M

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...

Management of euvolemic hyponatremia attributed to SIADH in the hospital: interim results from a prospective, observational, multi-center, global registry

Peri Alessandro , Verbalis Joseph , Greenberg Arthur , Johannsson Gudmundur , Ball Steven , Jorgensen Jens Otto , Chiodo Joseph

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...

Bone loss in inflammation-mediated osteoporosis: a role for the P2×7 receptor?

Kvist Torben , Petersen Solveig , Frederiksen Anja , Syberg Susanne , Jorgensen Niklas , Schwarz Peter

Bone loss in chronic autoimmune inflammatory diseases is a major clinical problem. Inflammation-mediated osteoposis (IMO) is the first animal model of generalized osteoporosis resulting from inflammation. The P2×7 receptor, an ATP-gated ion-channel, is primarily expressed on immune and bone cells. ATP is now seen as a novel inflammatory mediator, with P2×7 as main target of the pro-inflammatory activity. The P2×7-receptor has a regulatory role in bone formation ...

A986S or the R990G polymorphism in CASR does not explain hypercalciuria and low normal serum calcium

Rasmussen Anne Qvist , Jorgensen Niklas Rye , Tfelt-Hansen Jacob , Bevilacqua Maurizio , Schwarz Peter

The calcium receptor (CASR) serves as one of the main regulators of the calcium homeostasis. CASR is expressed in among other tissues parathyroid chief cells and kidney tubule cells. It has been hypothesized that CASR gene variations are responsible for low circulating calcium levels together with hypercalciuria and thereby increased risk of kidney stones. The CASR gene polymorphism A986S has been shown associated to elevated serum calcium levels in vivo<...
