Introduction:
Osteoarthritis (OA) is a degenerative joint disease characterized by cartilage degradation, bone remodeling, and pain. Recent evidence suggests that Vitamin D insufficiency, alterations in parathyroid hormone (PTH) levels, and dyslipidemia may play roles in the pathophysiology of OA, affecting calcium homeostasis and bone health. We investigated the association between Vitamin D, PTH levels, lipid profile, and calcium homeostasis in OA patients.
Materials And Methods:
This case-control study involved 200 participants, divided into OA and control groups, at a tertiary care center from April to May 2023. Serum levels of 25-hydroxyvitamin D, PTH, total cholesterol, HDL, LDL, triglycerides, and calcium were measured. Statistical analysis was conducted to assess correlations between these biomarkers and OA status.
Results:
OA patients demonstrated significantly lower Vitamin D levels and higher PTH and total cholesterol levels compared to controls. Vitamin D insufficiency was prevalent, with a notable correlation between decreased Vitamin D levels, elevated PTH, and dyslipidemia. These findings suggest a potential metabolic interplay affecting OA progression and symptomatology.
Conclusion:
The study highlights a significant association between Vitamin D insufficiency, altered PTH levels, and lipid dysregulation in OA patients, underscoring the importance of assessing these parameters in the clinical management of OA. Further research is needed to explore the therapeutic implications of correcting Vitamin D insufficiency and lipid abnormalities in OA.

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...

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...

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...
