Abstract

Objectives

Vitamin D is an important regulator of the immune system, and it has been shown that deficiency of vitamin D is significant environmental factor in some immune-mediated diseases such as Multiple Sclerosis (MS). In this study, we have compared serum 25 hydroxyvitamin (OH) D levels in Relapsing-Remitting Multiple Sclerosis (RRMS), clinically isolated syndrome (CIS), and control groups.

Methods

Forty patients with CIS and 60 patients who have been diagnosed RRMS between age 18–45, respectively, and followed up at Pamukkale University Faculty of Medicine, Department of Neurology, and 60 healthy individuals have been included in this study. Serum 25(OH) vitamin D, calcium, phosphorus, alkaline phosphatase, parathormone, insulin, and fasting blood glucose levels were studied for all three groups.

Results

A statistically significant difference was determined in the comparison of three groups for mean 25(OH) vitamin D levels. In the intergroup comparison of mean 25(OH) vitamin D; mean 25(OH) vitamin D level was determined to be statistically significantly lower in both RRMS and CIS groups compared to control group (p<0.05).

Conclusions

Since vitamin D deficiency poses a problem from the early stage of disease spectrum in both CIS patients and MS patients, 25(OH) vitamin D level should be routinely controlled, and replacement should be administered upon any deficiency state.
