Intensification of Anemia by Secondary Hyperparathyroidism in Hemodialysis Patients

The excessive amounts of parathyroid hormone in secondary hyperparathyroidism (SHPTH) is suggested to interfere with normal erythropoiesis.  In SHPTH, during chronic renal failure, due to the impairment of erythropoietin synthesis, this effect is more pronounced.  In the present study the role of secondary hyperparathyroidism in the severity of anemia was evaluated in hemodialysis patients (n=3...

Multiple myeloma in a patient with suspected hyperparathyroidism

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

Hyperparathyroidism.

Hyperparathyroidism is due to increased activity of the parathyroid glands, either from an intrinsic abnormal change altering excretion of parathyroid hormone (primary or tertiary hyperparathyroidism) or from an extrinsic abnormal change affecting calcium homoeostasis stimulating production of parathyroid hormone (secondary hyperparathyroidism). Primary hyperparathyroidism is the third most com...

Immunologic Differentiation of Primary Hyperparathyroidism from Hyperparathyroidism

A B S T R A C T Serum immunoreactive parathyroid hormone (IPTH) was measured by radioimmunoassay in 54 patients with primary hyperparathyroidism and in 18 consecutive patients with ectopic hyperparathyroidism due to nonparathyroid cancer without apparent skeletal metastasis. Although serum calcium concentration was higher in the group with ectopic hyperparathyroidism, serum IPTH was lower (rank...
