PTH: parathyroid hormone; FHH: familial hypocalciuric hypercalcemia.
* A PTH within the mid-upper normal range is inappropriately normal given hypercalcemia.
¶ If the patient is taking a thiazide diuretic or lithium, discontinue (if the drug can be stopped without exacerbating the underlying condition) and remeasure calcium and PTH in 3 months. Persistent hypercalcemia with elevated or high-normal PTH after drug withdrawal suggests that the drug has unmasked primary hyperparathyroidism.
Δ Refer to UpToDate content on distinguishing between primary hyperparathyroidism and FHH.
◊ Examples of non-PTH mediated hypercalcemia include humoral hypercalcemia of malignancy, vitamin D intoxication, granulomatous disease, vitamin A intoxication, and hyperthyroidism.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
