Secondary hyperparathyroidism is the medical condition of excessive secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels), with resultant hyperplasia of these glands. This disorder is primarily seen in patients with chronic kidney failure.

The most common cause of primary hyperparathyroidism is a sporadic, single parathyroid adenoma [5] resulting from a clonal mutation (~97%). Less common are parathyroid hyperplasia [6] (~2.5%), parathyroid carcinoma (malignant tumor), and adenomas in more than one gland (together ~0.5%).Primary hyperparathyroidism is also a feature of several familial endocrine disorders: Multiple endocrine ...
PAS II is defined as the association between autoimmune Addison's disease and either autoimmune thyroid disease, type 1 diabetes, or both. [5] It is heterogeneous and has not been linked to one gene. Rather, individuals are at a higher risk when they carry a particular human leukocyte antigen (HLA-DQ2, HLA-DQ8 and HLA-DR4). APS-II affects women ...
Conditions due to bone loss such as osteopenia and osteoporosis are common in tertiary hyperparathyroidism along with pathologic fractures. Pseudoclubbing of the digits can also be indicative of a severe tertiary hyperparathyroidism due to excess resorption at the distal phalanges. [8] [1] Diagnosis includes both clinical and laboratory ...
Secondary hyperparathyroidism typically occurs due to vitamin D deficiency, chronic kidney disease, or other causes of low blood calcium. [1] The diagnosis of primary hyperparathyroidism is made by finding elevated calcium and PTH in the blood. [2] Primary hyperparathyroidism may only be cured by removing the adenoma or overactive parathyroid ...
Nephrocalcinosis, once known as Albright's calcinosis after Fuller Albright, is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism. The term nephrocalcinosis is used to describe the deposition of both calcium oxalate and calcium phosphate. [1]
