Calcium pyrophosphate dihydrate and basic calcium phosphate (BCP) crystals are common in rheumatic diseases, causing joint degeneration and vascular calcification. These calcium crystal depositions lead to significant structural damage in humans.
Area of Science:
- Rheumatology and cardiovascular research.
Background:
- Calcium pyrophosphate dihydrate and basic calcium phosphate (BCP) crystals are prevalent in rheumatic diseases.
- Calcium crystal deposition is linked to inflammatory, degenerative arthritides, and periarthritis.
Purpose of the Study:
- To explore the structural consequences of calcium crystal deposition in joints and vasculature.
Main Methods:
- The study focuses on the association between intra-articular BCP crystal presence and radiographic degeneration.
- It examines the role of calcium hydroxyapatite crystal deposition in vascular calcification and atherosclerosis.
Main Results:
- Intra-articular BCP crystal presence correlates with the severity of radiographic joint degeneration.
- Calcium crystal deposition directly contributes to joint degeneration.
- Calcium hydroxyapatite deposition in arteries promotes inflammation and exacerbates atherosclerosis.
Conclusions:
- Calcium crystal deposition, including BCP and calcium hydroxyapatite, has significant structural consequences in rheumatic diseases and cardiovascular health.
- These depositions are key contributors to joint degeneration and the progression of atherosclerosis.

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...

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...
