Bone mineralization and bone mineral content in primary hyperparathyroidism.
Acta Endocrinologica
|February 1, 1977
Summary
Primary hyperparathyroidism significantly reduces bone mineralization and bone mineral content (BMC). These key indicators are lower in patients with high serum calcium, suggesting primary hyperparathyroidism as the cause.
Area of Science:
- Endocrinology
- Bone Metabolism
- Mineral Disorders
Background:
- Primary hyperparathyroidism is associated with bone density loss.
- Understanding the specific impact on bone mineralization and content is crucial for diagnosis.
Purpose of the Study:
- To evaluate bone mineralization and bone mineral content (BMC) in patients with primary hyperparathyroidism.
- To determine if these parameters correlate in the context of hyperparathyroidism.
Main Methods:
- Assessed bone mineralization using the phosphorus/hydroxyproline ratio (P/Hypro) from bone biopsies.
- Measured bone mineral content (BMC) via photon absorptiometry of the forearms.
- Analyzed data from 6 patients with primary hyperparathyroidism.
Main Results:
- Mean P/Hypro values were significantly lower than normal (P < 0.001).
- Mean BMC values were also significantly lower than normal (P < 0.02).
- No significant correlation was observed between P/Hypro and BMC in these patients.
Conclusions:
- Low bone mineralization (P/Hypro) and BMC are characteristic of primary hyperparathyroidism.
- These findings, coupled with elevated serum calcium, support the diagnosis of primary hyperparathyroidism.
- The lack of correlation suggests distinct pathophysiological pathways affecting mineralization and content in this condition.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:18The Bone Matrix
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:21Skeleton and Calcium Homeostasis
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
00:59The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...
