Summary
Recombinant human parathyroid hormone (PTH) is an anabolic osteoporosis treatment. Sequential PTH therapy with antiresorptives effectively increases bone mineral density and improves bone structure.
Area of Science:
- Endocrinology
- Bone Biology
- Pharmacology
Background:
- Recombinant human parathyroid hormone (PTH 1-34) is the sole approved anabolic agent for osteoporosis.
- Anabolic agents stimulate bone formation, unlike antiresorptive drugs that inhibit resorption.
Purpose of the Study:
- To evaluate the role of PTH in osteoporosis treatment, considering combination and sequential regimens with antiresorptive agents.
- To understand the impact of PTH on bone mineral density and micro-architecture.
Main Methods:
- Review of recent investigations on PTH (1-34) and PTH (1-84) peptides.
- Analysis of combination and sequential therapeutic strategies involving PTH and antiresorptive agents.
Main Results:
- Concurrent PTH and bisphosphonate use in treatment-naive patients shows no added bone benefit.
- Sequential PTH followed by antiresorptives significantly increases bone mineral density.
- Administering PTH after antiresorptive therapy also yields substantial bone density gains.
Conclusions:
- Sequential PTH therapy, particularly PTH followed by antiresorptives, is a highly effective strategy for increasing bone mineral density.
- PTH can repair bone micro-architecture and improve bone mass and geometry.
- Further research is needed on optimal PTH treatment duration, dosing, resistance mechanisms, and rechallenge efficacy.

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...

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...

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.
01:21Skeleton 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.
00:51Synthesis 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...

01:27Roles of Electrolytes: Calcium and Phosphate
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
