ABSTRACT

Parathyroid hormone PTH) plays a very important role in skeletal metabolism. This hormone is important because it regulates calcium homeostasis and bone remodeling by altering osteoblast and osteoclast activity. Research indicates that continuous exposure to PTH can promotes bone resorption and intermittent administration has been shown to have anabolic effects that improve bone structure and strength. This research examines the influence of PTH on bone integrity using evidence from both animal and human studies. A literature review in PubMed was conducted to explore PTH and better understand its therapeutic potential.
Research indicates that in aged rat models intermittent PTH administration significantly increases vertebral bone mass and improves biomechanical properties, including load, stiffness, and energy to failure. These improvements show vertebral strength and resistance to fracture, indicating that PTH positively affects bone quality. Human data from individuals with Hypoparathyroidism show that treatment with recombinant human PTH leads to measurable changes in trabecular microarchitecture. Imaging techniques and element analysis also indicate an increase in cancellous bone strength and elastic modulus, that improves bone structural organization and mechanical integrity. A synthetic PTH analog called Teriparatide has also shown to improve bone strength when administered intermittently. In conclusion, data from both animal and clinical studies reveal that parathyroid hormone is a potent modulator of bone strength and a promising therapeutic strategy for improving skeletal integrity and reducing fracture risk in metabolic bone disorders.
