Q

Explain how PTH works?

Explain the difference between primary, secondary and tertirary

Explain what PTH and Ca levels you would find with each type

A

PTH + vit D -> increase serum Ca

PTH does this by:
= increasing osteoclast activity
= causing renal retention of Ca
= increasing gut absorption (vit D does this too)

Primary - mostly caused by adenomas
Secondary - caused by parathyroid gland hyperplasia in response to one of the mechanisms not working properly e.g. renal failure
Tertiary - as a result of all 4 paratyhyroid glands hyperplasia due to prolonged secondary hyperparathyroidism

Primary
- Increased PTH, increased Ca

Secondary
- increased PTH, normal or low Ca

Tertiary
- increased PTH, normal or high Ca
