obesity is one of the health problems in the developing and developed countries. obesity subjects the individuals with metabolic and endocrine disorders. it is obvious that vitamin d deficiency or insufficiency may lead to secondary hyperparathyroidism. thus, obesity increases the risk of vitamin d deficiency. considering the high prevalence of vitamin d deficiency in children and adolescents w...

Introduction: secondary hyperparathyroidism is listed among the possible reasons for intensifying the anemia and resistance to erythropoietin therapy in hemodialysis patients. Although its exact mechanism is not entirely clarified, but shift of bone marrow cells to adipocytes, bone marrow fibrosis and decreased calciteriol can be the causes. However, the role of secondary hyperparathyroidism in...

Myelofibrosis is reported in patents with primary hyperparathyroidism. It is also was reported in patents with sec- ondary hyperparathyroidism due to end-stage renal disease or Vitamin D dependent rickets .We present a case of celiac disease and osteomalacia which leads to secondary hyperparathyroidism and myelofibrosis.

introduction: osteodystrophy is one of the long term complications of chronic renal failure and is expressed in two formslow turn over and high turn over. it is an important cause of morbidity in patients with renal failure and if diagnosed and managed properly, many problems of these patients can be resolved. in this study we evaluated the prevalence of hyperparathyroidism in hemodialysis pati...

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...

We reviewed the etiology and management of secondary and tertiary hyperparathyroidism. Secondary hyperparathyroidism is characterized by an increase in parathyroid hormone (PTH) that is appropriate and in response to a stimulus, most commonly low serum calcium. In secondary hyperparathyroidism, the serum calcium is normal and the PTH level is elevated. Tertiary hyperparathyroidism is characteri...
