Overview
The clinical features of hypocalcemia may vary widely, and range from asymptomatic to life-threatening complications.The main factors that influence serum calcium levels are parathyroid hormone (PTH), vitamin D, ionized calcium, and phosphate. Hypocalcemia is commonly encountered in patients who are hospitalized. Under treatment or improper treatment of hypocalcemic emergencies can lead to significant morbidity. Death is rare but has been reported in hypocalcemia patients.
Natural History
- The clinical presentation of hypocalcemia may vary widely and range from asymptomatic to life-threatening complications.[1]
- Parathyroid hormone (PTH), vitamin D, ionized calcium, and phosphate are the main regulators that influence serum calcium levels.[2][3][4]
- As the people age the calcium requirement also increases and risk for calcium deficiency also increases by age.
- Poor calcium intake, certain medications, dietary intolerance, hormonal changes and genetic factors may lead to hypocalcemia.
Complications
- Common complications of hypocalcemia include[5][6][7][8][9][10][11][12][13][14][15]
- Bone disease such as:
- Osteoporosis, complications from osteoporosis include
- Cardiovascular collapse with cardiac arrhythmia
- The ECG hallmark of hypocalcaemia is prolongation of the corrected QT interval.
- Hypocalcemic cardiomyopathy
- Hypotension which is unresponsive to fluids and vasopressors
- Dysrhythmias
- Laryngospasm
- Seizures
- Tetany
- Basal ganglia calcification
- Parkinsonism
- Hemiballismus
- Choreoathetosis
- Intradialytic hypotension
- Bone disease such as:
Prognosis
- Prognosis is generally good when hypocalcemia treated optimally.
- The concentrations of ionized calcium on day 3 could be very useful for the prediction of mortality and disability in patients with moderate and severe traumatic brain injury (TBI).[16][17]
