Study summary

The aim of this study is to assess the clinical, laboratory and vascular calcification outcome within 6 months duration in patients undergoing surgical parathyroidectomy (total, subtotal, and total with autotransplantation)

Read the detailed description

All patients above the age of 18, with end stage renal disease maintained on regular hemodialysis and are indicated for surgical parathyroidectomy.

The indications for parathyroidectomy included persistently elevated intact parathormone hormone levels of greater than 500 pg/mL, uncontrolled hypercalcaemia with hyperphosphataemia or clinical symptoms of secondary hyperparathyroidism refractory to medical treatment. These symptoms included bone pain, pruritus, fracture, fatigue and calciphylaxis

These patients will be exposed to pre-operative evaluation of clinical, laboratory and vascular calcification in abdominal aorta and coronary calcium scoring using ECG- gated non contrast CT in hemodialysis patients undergoing parathyroidectomy

Post-operative evaluation of clinical, laboratory and vascular calcification in abdominal aorta and coronary calcium scoring using non contrast CT will be done 6 months post-operative

Assessment of the relation between preoperative and postoperative measures

Patients with the following criteria will be excluded:

  1. chronic kidney disease patients not yet on regular Hemodialysis
  2. patients who had primary hyperparathyroidism
  3. patients who had received kidney transplantation
  4. patients who underwent repeated parathyroidectomy
  5. patients who were lost to follow-up or with missing data.

What researchers measure

Primary outcomes

  1. emergent adverse postoperative events and assessment of the degree of vascular calcification

    assessment of emergent adverse postoperative events as bleeding, indication for mechanical ventilation and intensive care unit admission, vocal cord injury and development of hypoparathyroidism with persistent hypocalcemia assessment of degree of vascular calcification via measuring calcium scoring through ECG gated non contrast CT

    Time frame: 6 months

Secondary outcomes

  1. Emergent Adverse events on laboratory parameters

    assessment of s.calcium in mg/dl s.phosphorus ( mg/dl) and level of intact parathormone hormone in ( pg/mL)

    Time frame: 6 months

  2. Emergent Adverse events on Quality of life through assessing physical functioning, limitations due to physical health, limitations due to emotional problems, Energy/Fatigue, Emotional wellbeing, Social functioning, Pain, and General health

    Emergent Adverse events on Quality of life using short form 36 heath survey questionaire to assess physical functioning, limitations due to physical health, limitations due to emotional problems, Energy/Fatigue, Emotional wellbeing, Social functioning, Pain, General health

    Time frame: 6 months

  3. Emergent Adverse events on clinical status of the patient

    improvement of clinical symptoms related to hyperparathyroidism prior to surgery, occurrence of surgical complications related to parathyroidectomy procedure, cardiovascular problems, bone aches and disabilities, pruritis

    Time frame: 6 months
