Multiple
sclerosis (MS) is an autoimmune disease in which the body’s immune system
attacks the central nervous system (brain and spinal cord). As a result, the
protective myelin coating (sheath) on nerve cells which functions much like
insulation on an electrical wire, becomes damaged, and signals from the nerves
can become slow or blocked. Characteristic lesions called “multiple scars” can
be seen on an MRI in a person with MS, which gives the disease its name.
Symptoms
of MS can include weakness, numbness, tingling, balance and gait problems,
problems with thinking, mood, and fatigue, bowel and bladder problems, sexual
dysfunction, and problems with speech, swallowing or vision. MS patients often
exhibit intolerance to heat making damaged nerves less efficient, bringing on
symptoms.
There
are 400,000 MS patients in the US, and over 2.5 million worldwide. The disease
is of particular concern in Western New York where the incidence is
significantly higher. This is because MS is correlated with colder climates and
living above 40 degrees from the equator. Higher
incidences are also seen in Europe and in Caucasians of Scandinavian ancestry,
although MS can affect any ethnic group.
MS is
thought to occur as result of geography, environmental influences, and possibly
genetics. Currently researchers
believe low vitamin D levels may affect MS. Symptoms usually occur between ages of 15 and 45 and two to
three times more likely in women. Interestingly, MS exacerbations and relapses
are less frequent during pregnancy, urging researchers to investigate the role
of female hormones on MS.
Seven
disease modifying medications (Avonex, Betaseron, Copaxone, Gilenya,
Novantrone, Rebif, Tysabri) are currently approved for the treatment of
Relapsing Remitting Multiple Sclerosis (RRMS). In September 2010, fingolimod
(Gilenya) became the
first oral medication to enter the market. According to Malti J. Patel, M.D. who has conducted several
MS clinical trials at the Dent, “This is a very exciting time for MS, and more
drugs are expected to enter the market in the coming years, giving patients and
physicians options to tailor MS therapy to specific patients.”
But Dr.
Patel urges patients to “stick with what works for you and work with your
neurologist to choose the most effective medication for you, and one that you
are willing to take regularly.” She says, “All MS drugs are effective, and have
advantages and disadvantages.
Currently approved treatments can slow disease progress and provide
improved quality of life, allowing patients to live more normal lives for a
longer period of time.”
Dr. Patel is
Medical Director for the Multiple Sclerosis Clinic at DENT Neurologic Institute
(DENT). She is an Attending Neurologist at DENT and a consulting attending for the Primary Brain Tumor and
Neurology Clinic at Roswell Park Cancer Institute. To make an appointment to
see Dr. Patel call 716-250-2000.
DENT is conducting a research
study for patients between the ages of 18 and 55 being treated for a relapsing
form of MS, who have had symptoms return twice during the past two years or
once within the past year.
Qualified participants will receive study-related exams and either an
investigational drug, or an approved medication called Rebif. To find out more contact Michelle
Rainka,PharmD at 716-250-2038 or Kristin Surdam at 716-819-4117.
