title: Pancreatitis secondary to hyperparathyroidism during pregnancy.
abstract: BACKGROUND
  It has been suggested that magnesium can be used to reduce serum calcium levels seen with hyperparathyroidism during pregnancy, thus reducing maternal and fetal risk.
  
  
  METHODS
  A young woman presented at 32 weeks' gestation with abdominal pain from pancreatitis caused by hyperparathyroidism from a parathyroid adenoma. She was started on magnesium sulfate tocolysis for preterm labor. During treatment, serum parathyroid hormone was undetectable, but serum calcium and vitamin D-1,25 were elevated. When magnesium was discontinued, her vitamin D-1,25 was suppressed and the parathyroid hormone was elevated.
  
  
  CONCLUSIONS
  For some patients, because of persistent hypercalcemia, magnesium sulfate might not be a viable treatment option for hyperparathyroidism during pregnancy.
