Brief Summary:

Patients with primary hyperparathyroidism (pHPT) often present with fatigue, psychological and cognitive symptoms. Improvement in these symptoms after parathyroid adenomectomy (PTX) has been reported. But physicians lack a method to attribute the symptoms to pHPT and to predict the reversibility after PTX.

This study aims to evaluate short-term calcimimetic treatment as a tool for predicting the outcome of PTX on muscle strength, quality of life, psychological symptoms, and cognitive function in patients with pHPT.

Material and Methods: 118 patients scheduled for PTX at Karolinska University Hospital, Sweden, will have a four week treatment with calcimimetics (Mimpara®) before undergoing surgery. Biochemicals, muscle strength, quality of life, psychological symptoms and cognitive function will be analysed at baseline, after four week follow-up and postoperatively.

Hypothesis: The outcome of short-term calcimimetic treatment can predict the outcome of PTX on muscle strength, quality of life, psychological symptoms, and cognitive function in patients with pHPT

Primary Outcome Measures :
  1. Quality of life [ Time Frame: after four weeks of calcimimetic treatment and postoperatively ]
    Health related quality of life measured by EORTC QLQ-C30 (total score)


Secondary Outcome Measures :
  1. Psychological well-being [ Time Frame: After four weeks of calcimimetic treatment and postoperatively ]
    Psychological well-being, evaluated with the validated form Positive States of Mind, PSOM

  2. Anxiety and depression [ Time Frame: After four weeks of calcimimetic treatment and postoperatively ]
    Depression and anxiety; evaluated with the Hospital Anxiety and Depression (HAD) scale

  3. Muscle strength [ Time Frame: After four weeks of calcimimetic treatment and postoperatively ]
    Leg muscle strength measured by Timed stand-test (repeated uprise from chair)

  4. Biochemical data [ Time Frame: After four weeks of calcimimetic treatment and postoperatively ]
    AE/SAE recording and safety blood samples; serum levels of p-PTH, s-ionized calcium, p-total calcium, p-albumin, p-creatinine, p-phosphate, s-25-OH-D and thyroid-stimulating hormone (TSH)

  5. Cognitive function [ Time Frame: after four weeks of calcimimetic treatment and postoperatively ]
    Cognitive function evaluated with Montreal cognitive assessment (MoCA-test)
