1
Milk-alkali Syndrome can lead to?
Acute Renal Failure
2
When should you measure PTH levels in Milk Alkali Syndrome?
In milk-alkali syndrome, vigorous treatment of hypERcalcemia with saline diuresis and loop diuretics may lead to hypOcalcemia. With the hypocalcemia, PTH will rise and may reach levels above reference range. Therefore:
PTH levels should be determined BEFORE or AT THE INITIATION of tx.
