  Purpose

The investigators hypothesize that vitamin D supplementation may ameliorate interferon beta-induced flu-like symptoms, owing to reduced release and activity of the cytokines that are in correlation with this adverse event. Vitamin D supplementation may also positively affect injection site reactions due to its immunomodulatory effects. Vitamin D may also augment the therapeutic efficacy of interferon beta among multiple sclerosis (MS) patients. Vitamin D intake may influence melatonin levels of MS patients as they share the same nuclear receptor.

Criteria

Inclusion Criteria:

  • Male and female patients with a diagnosis of RRMS according to the McDonald criteria (2005)
  • At least 18 years of age
  • Patients are treated with IFN-beta for RRMS. The decision to treat with IFN beta will be independent from this study protocol.
  • Patients will be either newly diagnosed, who are going to start IFN beta therapy for the first time or RRMS patients who suffer from FLS while being treated with IFN beta.
  • Insufficient blood levels of 25-hydroxy-vitamin D (below 75nmol/l according to current definitions.
  • EDSS score up to 7
  • Willing and able to give informed consent

Exclusion Criteria:

  • Patients having abnormalities of vitamin D related hormonal system other than low dietary intake or decreased sun exposure will be excluded. Namely, malabsorption [Celiac, Whipple, Inflammatory bowl disease, Intestinal bypass surgery, Short bowel syndrome, Cirrhosis, Nephrotic syndrome, Hyperthyroidism, Renal failure [creatinine clearance of less than 40 ml/min], Rickets, Hypoparathyroidism, Hypercalcemia at baseline, known malignancy, granulomatous disorders (Sarcoidosis, Tuberculosis, Silicosis) and Lymphomas.
  • Patients who take medications that influence vitamin D metabolism, other than corticosteroids, will be also excluded. Namely, Orlistat, Anticonvulsants [Phenobarbital, Primidone, Phenytoin], Rifampin, Isoniazide, ketoconazole, 5FU and Leucovorin
  • Patients with conditions with increased susceptibility to hypercalcemia will be excluded too: known arrhythmia or heart disease, treatment with Digitalis, or Hydrochlorothiazide.and those who suffer from nephrolithiasis.
  • Other Central Nervous System disorders than RRMS
  • Psychiatric disorders such as psychosis, bipolar disorder or substance abuse
  • Pregnancy
  • Contra-indication to treatment with IFN-beta
