Summary
Recombinant human parathyroid hormone (rhPTH) therapy offers bone anabolic benefits for osteoporosis, reversing bone loss. However, it is not superior to anti-resorptive agents and is best reserved for severe spinal osteoporosis cases.
Area of Science:
- Endocrinology
- Bone Biology
- Pharmacology
Background:
- Bone anabolic therapy using recombinant human parathyroid hormone (rhPTH) analogues like teriparatide (rhPTH[1-34]) and full-length rhPTH(1-84) has been available for osteoporosis treatment for a decade.
- These rhPTH therapies are administered via daily subcutaneous injections, with teriparatide being the marketed form in the USA.
Purpose of the Study:
- To review the anti-fracture efficacy of rhPTH therapies based on randomized controlled trials.
- To compare the treatment effects of rhPTH with those of anti-resorptive agents.
- To explore recent findings on alternative administration schedules for rhPTH, such as less than once-daily or intermittent/cyclic therapy.
Main Methods:
- Review of randomized controlled trials evaluating the anti-fracture efficacy of rhPTH.
- Analysis of studies investigating novel administration regimens (less than once-daily, intermittent/cyclic therapy).
- Comparative analysis of rhPTH treatment effects against established anti-resorptive agents.
Main Results:
- rhPTH demonstrates bone anabolic effects by altering bone remodeling, geometry, and mineral density.
- Anti-fracture efficacy of rhPTH is comparable to potent anti-resorptive agents.
- Recent studies explore alternative rhPTH administration schedules.
Conclusions:
- While rhPTH reverses osteoporosis progression, its anti-fracture efficacy is not superior to anti-resorptive agents.
- The high cost of rhPTH limits its use compared to anti-resorptives.
- rhPTH is recommended for severe spinal osteoporosis, particularly in patients unresponsive to anti-resorptive therapy.

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.
01:17Hormones 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...

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
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...

01:25Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:31Essential Minerals for Bone Health
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
