Clinical Trial Summary

The investigators hypothesise that parathyroid hormon (PTH) depletion interferes with normal activity of the hypothalamus-pituitary-adrenal (HPA)-axis and the renin-angiotensin-aldosterone-system (RAAS), which in turn may impact morbidity and quality of life. The main objective of the current study is to test if PTH deficiency influences the secretion of corticosteroids and whether any abnormalities in the HPA-axis and the RAAS-system can be reversed by PTH infusion.


Clinical Trial Description

Visit 1: Optimizing conventional treatment regarding s-magnesium, s-calcium, s-phosphorous and 25-hydroxyvitamin D (25(OH)D)-levels.

Visit 2 (In-hospital 4-7 days): Day one: 24h microdialysis sampling, venous blood sampling and 24h urine will be collected. Day 2: Start of PTH pump-treatment. Day 3-x: dose adjustment of PTH pump therapy according to Calcium Levels, the first two days after started PTH six daily venous blood-samplings will be performed. Day x: 24h microdialysis sampling and 24h urine-sampling and a venous blood sampling. Restart of conventional treatment.

The Control patients (healthy volunteers and patients with hyperparathyroidism) will perform 24h microdialysis-sampling only. ;
