Summary
Patients with Graves' disease exhibit lower bone mineral density and degraded bone microarchitecture. Further research is needed to understand bone recovery after treatment for this common cause of thyrotoxicosis.
Area of Science:
- Endocrinology
- Bone Metabolism
- Rheumatology
Background:
- Graves' disease (GD) is the leading cause of thyrotoxicosis.
- Bone mineral density (BMD) is often reduced in GD patients.
- Bone strength relies on microarchitecture, assessable by Trabecular Bone Score (TBS).
Purpose of the Study:
- To compare bone microarchitecture using TBS in active Graves' disease patients versus healthy controls.
- To evaluate the relationship between BMD, TBS, and biochemical parameters in GD.
Main Methods:
- Cross-sectional study of 50 active GD patients and 50 controls.
- Dual-energy X-ray absorptiometry (DXA) used for BMD and TBS measurements.
- Biochemical parameters were assessed in both groups.
Main Results:
- Significantly reduced BMD at lumbar spine, femoral neck, total hip, and distal radius in GD patients.
- Significantly lower TBS in GD patients (1.263 ± 0.101) compared to controls (1.368 ± 0.073).
- Serum thyroxine (T4) and lumbar spine BMD predicted TBS on multivariate analysis.
Conclusions:
- Active Graves' disease is associated with reduced bone density and degraded bone microarchitecture.
- Long-term studies are necessary to determine bone microarchitecture recovery after achieving euthyroidism.

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...

01:09Spongy Bone
4.6K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:40Bone Remodeling
38.4K
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
2.7K
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
3.0K
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...

01:18The Bone Matrix
3.2K
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...
