Hypercalcemia is a common underdiagnosed metabolic abnormality, since it is frequently asymptomatic. HPT and malignant humoral hypercalcemia share some similarities such as: However, patients with hypercalcemia associated with malignancy are usually clinically very ill with mestatasis in multiple organs.
The intact PTH iPTH serum measurement is very important for definitive diagnosis, since iPTH is elevated or normal in primary hyperparathyroidism and supressed in malignancies. Hypercalcemia in malignancies may be due to humoral factors secreted by tumors that act on target organs and change normal calcium homeostasis. Also, local factors secreted by tumors in bone, either metastatic or hematological, may stimulate osteoclastic bone resorption.
The parathyroid hormone-related protein PTHrP is responsible for the majority cases of hypercalcemia associated to solid tumors. Other factors like interleukin-6, tumoral growth factor, tumoral necrosis factor and interleukin-1 can modulate the end-organ effects of PTHrP and in some tumors they can directly stimulate the osteoclasts such as in the case of multiple myeloma. Hypercalcemia can less frequently be associated with some endocrine diseases like thyrotoxicosis, pheochromocytoma, Addison’s disease and multiple endocrine neoplasia types I and IIA.
Some drugs may cause this metabolic abnormality, mainly vitamin D, thiazide diuretics, and lithium. The differential diagnosis of hypercalcemias is essencial for the appropriate treatment of this metabolic abnormality. Com a descoberta do PTHrP, este tem sido implicado na maioria destes casos.
