The Parathyroid Glands

The 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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Synthesis and Functions of Calcitonin

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

Hormones and Bone Tissue

Hormones 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...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Skeleton and Calcium Homeostasis

Skeleton 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.

Summary

This summary is machine-generated.

Primary hyperparathyroidism (PHPT) is linked to early aortic valve calcification, even in mild cases. Parathyroid hormone (PTH) levels, not calcium, predict this subclinical cardiovascular issue.

Area of Science:

Cardiology
Endocrinology
Metabolic Bone Disease

Background:

Cardiovascular disease presence in primary hyperparathyroidism (PHPT) remains unclear.
PHPT is a condition affecting calcium regulation and bone health.

Purpose of the Study:

To compare aortic valve structure and function in PHPT patients versus controls.
To investigate the relationship between PHPT and subclinical aortic valve calcification.

Main Methods:

A case-control study involving 51 PHPT patients and 49 controls.
Measurement of aortic valve calcification area and transaortic pressure gradient.
Analysis of parathyroid hormone (PTH) and serum calcium levels.

Main Results:

PHPT patients showed significantly higher aortic valve calcification area compared to controls.
Aortic valve calcification area correlated positively with PTH levels.
Serum PTH was an independent predictor of aortic valve calcification, outperforming traditional risk factors.

Conclusions:

Mild PHPT is associated with subclinical aortic valve calcification.
PTH levels, not serum calcium, predict aortic valve calcification.
PTH is a significant predictor of aortic valve calcification in PHPT.
