Primary hypoparathyroidism is an uncommon endocrine disorder

Management of Primary Hypoparathyroidism
A Single Centre Audit
S Sighakoli, T Wheatley
INTRODUCTION
Primary hypoparathyroidism is an uncommon endocrine disorder characterized by hypocalcaemia associated with an
inappropriately low parathyroid hormone concentration. European guidelines1 state that
• all patients should have individualised targets for calcium and phosphate
• relevant biochemical variables should be monitored at least annually
• quality of life should be evaluated
• patients should be taught to recognise hypocalcaemia and hypercalcaemia
• patients should be educated regarding potential complications
METHODS
A local retrospective audit of 18 patients aged 25 to 85 years with primary hypoparathyroidism was undertaken. Data were
obtained from clinical notes, a computerised endocrine database and local pathology system. Patients with end stage renal
disease or less than one year follow-up were excluded.
RESULTS
-16/18 patients were female
-No patient received education
regarding identifying symptoms of
abnormal Calcium levels
-50% had hyperphosphataemia

CONCLUSIONS
There is scope to improve the
management of hypoparathyroidism
mainly in the regular monitoring of
biochemical variables.
Although guidelines are not based
on strong evidence, they at least
provide a useful follow up strategy
and identify clear targets.
