A drug that boosts body's receptivity to Vitamin D

Patients taking a multiple sclerosis drug, interferon-beta, receive almost three times as much vitamin D from exposure to sun than those who do not take the treatment, according to a new study.

Multiple sclerosis (MS) is an autoimmune disease that damages the brain and spinal cord (central nervous system).

There is currently no cure, but treatments are available to

ease some of the symptoms.

MS is caused by damage to the myelin sheath that protects

nerve cells.

This damage causes the nerve signals to slow down or

cease. Inflammation occurs when the body's own immune cells attack the nervous system. This can affect any area of the brain, optic nerve, and spinal cord, journal Neurology

reported.

This observation by the Menzies Research Institute( Menzies) Tasmania, based on data from 178 MS patients,

suggests that one of the main treatments for MS may also

increase the amount of vitamin D patients receive from sun

exposure.

Around 60 per cent of MS patients are treated with interferon-beta. Derived from a naturally-occurring component of the human immune system, the drug has been found to reduce the frequency of relapse and other specific symptoms of MS, according to a statement of Menzies Institute, according to the Menzies statement.

Steve Simpson Jr, who co-authored the study with Niall

Stewart from Menzies, said the findings suggest that part of

the therapeutic effects of interferon-beta on MS may be

through its effects on vitamin D, since it has the ability to

reduce inflammatory pathways in the immune system.

"Not only did we find that persons taking interferon-beta

had higher vitamin D levels than those not taking it, we also

found that this increase in vitamin D was due to enhancement of the association between sun and vitamin D, with persons on interferon-beta having nearly three-times as much vitamin D from similar amounts of sun exposure to those not taking interferon-beta," Simpson said.
