To determine whether the attenuated salivary cortisol response in children with asthma can be explained by the maintenance use of inhaled cortiocosteroids, the chronic inflammatory disease, or the attenuated exercise capacity.
1. To explore the validity and usefulness of Bone Microindentation Technique (BMT) in the assessment of bone quality in patients with osteoporosis and a spectre of bone diseases characterised with (localised) increased bone turnover. 2. To study the…
To determine the sensitivity and specificity of salivary metanephrines and in patients with PCC/sPGL.
Objectives: Part 1) To assess the prevalence of PA in general practice (part 1 of this study);Part 2) To describe differences of cardiorenovascular damage in newly diagnosed hypertensive patients with versus without PA (part 2 of this study);Part 3…
ObjectiveThe main goal of this investigation is to evaluate the thyroid hormone response in patients with TMNG and control subjects in response to various pharmacological and physiological stimuli, administered according to the dynamic exposure test…
The primary objective of our study is to investigate the performance of FCH-PET as a second-line imaging modality for localizing hyper-functioning parathyroid gland(s) in patients with biochemically proven PHP for whom surgery is indicated, thereby…
Primary objective:to identify new and improved disease biomarkers and establish the biochemical and molecular basis for variations in the clinical presentation of the different groups of tumors.Secondary objectives:• compare the diagnostic utility…
In order to confirm and externally validate the novel panel of genes identified in our study (06/101/K) to be significantly predictive of recurrent implantation failure, we will recruit 50 additional subjects treated by IVF who have undergone at…
We aim to investigate thirst in the above mentioned patient groups, applying a Visual Analogue Scale (VAS) and, where ethically acceptable, a new thirst provocation test which we will develop in a group of healthy probands. Using these tools, we aim…
Our primary objectives are:- to estimate the prevalence of central adrenal insufficiency , defined as a plasma cortisol response <500 nmol/l in the low-dose ACTH test (see paragraph 8.3.5 of the protocol). - to describe immune dysfunction, i.…
To investigate the correlation between androstenedion in saliva and serum in all patients that have a request for androstenedion in serum.To collect age related reference ranges for healthy children on three different time points.
To study the incidence of TART in children with congenital adrenal hyperplasia with new imaging techniques such as high frequency ultrasound and elastography

The aim of the present study is to assess the necessity of dietary restrictions before sampling for the biochemical diagnosis of pheochromocytoma. Therefore, the short-term influence of a catecholamine-rich diet on plasma free and total metanephrine…
The aim of this study is to classify hyothalamic dysfunction in patients treated for pituitary tumors. The hypothalamic functions will be investigated in different studygroups, these groups each have a different risk on hypothalamic dysfunction.
Protocol 1: To determine whether pituitary dysfunction is present at intermediate duration of follow-up after traumatic brain injuryProtocol 2: To determine whether injury to brain tissue that explains traumatic brain injury-induced pituitary…
To detect differences between ACC patients and controls without ACC, and between the diseased and healthy adrenal gland of ACC patients, in microRNA (miRNA), circulating cell-free tumor DNA (ctDNA), circulating tumor cells (CTCs), and steroid…
Primary objective: To assess and compare the difference in thyroid gland secretion capacity by measuring maximal FT4 and FT3 response upon intramuscular administration of 0.9mg Thyrogen assessed by AUC0-48hours in SCT subjects and healthy controls.…
Primary objectives pancreatic cancer:• In this clinical pilot study, we will assess the effect size to perform a power calculation for a subsequent clinical trial. Therefore we want to evaluate the ability of metabolic 7T MRI imaging to determine…
To assess whether premature aging of both the innate and adaptive arms of theimmune system are associated with COVID-19 morbidity and mortality. Identify immune (andendocrine) parameters that might be of use in predicting disease progression and…
