Vitamin D levels in Swiss multiple sclerosis patients

Area of Science:

• Neurology
• Endocrinology
• Nutritional Science

Background:

• Vitamin D levels in Swiss multiple sclerosis (MS) patients remain uncharacterized.
• Previous research suggests a potential link between vitamin D status and MS disease activity.

Purpose of the Study:

• To determine the 25-hydroxy-vitamin D (25(OH)D) levels in individuals with multiple sclerosis in Switzerland.
• To assess the prevalence of vitamin D deficiency within this patient cohort.

Main Methods:

• A cross-sectional case-control study design was employed.
• 25(OH)D levels were measured in 80 Swiss MS patients.

Main Results:

• The mean 25(OH)D level was 57.0 ± 29.7 nmol/l.
• 21.3% of patients exhibited 25(OH)D levels ≤37 nmol/l, indicating deficiency.
• 75% of patients had levels ≤70 nmol/l, suggesting suboptimal levels in a majority.

Conclusions:

• A significant prevalence of 25(OH)D deficiency was observed in the studied Swiss MS patient population.
• These findings highlight the need for monitoring vitamin D status in MS patients in Switzerland.
