Multiple sclerosis (MS) patients experiencing relapses show high rates of low bone mineral density (BMD) and vitamin D deficiency. Standard fracture risk tools are inadequate for this group, necessitating a new management approach.
Area of Science:
- Neurology
- Endocrinology
- Bone Metabolism
Background:
- Multiple sclerosis (MS) is a chronic neurological disease impacting bone health.
- Relapsing forms of MS often involve corticosteroid treatment, a known risk factor for bone loss.
- Bone health and vitamin D status in MS relapse cohorts require thorough evaluation.
Purpose of the Study:
- To assess bone health and vitamin D levels in patients with relapsing multiple sclerosis.
- To identify factors influencing bone health in this population.
- To develop a management algorithm for bone health in relapsing MS.
Main Methods:
- Prospective study of 56 consecutive patients with acute MS relapses.
- Bone health assessment via Dual Energy X-ray Absorptiometry (DEXA) and serum vitamin D levels (25(OH)D).
- Statistical analysis to compare groups and identify predictive variables; literature review for protocol development.
Main Results:
- 51% of patients exhibited low bone mineral density (BMD) (T-score < -1.0); 3 were osteoporotic (T-score < -2.5).
- 62% of subjects were vitamin D deficient (25(OH)D < 50 nmol/L).
- Predictive variables, including prior corticosteroid use, did not significantly correlate with reduced BMD.
Conclusions:
- High prevalence of low BMD and vitamin D deficiency observed in relapsing MS patients.
- Existing tools like the WHO FRAX algorithm are insufficient for assessing bone status in this demographic.
- A simplified clinical management algorithm for bone health in relapsing MS is proposed.

Bone Disorders
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...
Role of Vitamins in Maintaining Bone Health
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...

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...
