About SHPT

What is secondary hyperparathyroidism in chronic kidney disease?

Characterised by excessive secretion of parathyroid hormone (PTH) and hyperplasia of the parathyroid glands, secondary hyperparathyroidism (SHPT) is a maladaptive response to disrupted mineral and vitamin D homeostasis due to decline in renal function.2,3

Why is early diagnosis and treatment of SHPT crucial?

Without prompt and effective treatment, patients with SHPT may be at increased risk of developing:

  • Reduced responsiveness to SHPT therapy as a result of the parathyroid glands becoming less sensitive to vitamin D and calcium signalling3–5
  • Bone and cardiovascular complications, which are linked with increased morbidity and mortality2,6–15
