Pregnancy hormone may be key to controlling MS

Doctors may be on the cusp of developing a new treatment for multiple sclerosis. It isn't a complex new drug, but something that already exists within the human body.

37-year-old melissa sherak glasser has had multiple sclerosis since she was a teenager.

Melissa says, "My body has experienced a lot of different things from numbness to not being able to feel temperature, to not being able to use my legs, to seeing double."

But remarkably, during each of her 4 pregnancies, her symptoms diminished.

"I knew there was something about being pregnant that made me feel really, really great," says Melissa.

But what was it that made her feel better?

Researchers at UCLA think it was estriol, a hormone produced by the placenta.

They believe that just like it protects a fetus from attacks by a mother's immune system, it protects a MS patient's nervous system from attack.

Dr. Rhonda Voskuhl, the lead researcher at UCLA says, "We gave a dose of estriol to induce a pregnancy level in the patient's blood and by doing that we had recreated some of the particular effects of pregnancy."

In fact, in a pilot study, non-pregnant women with m-s who took an estriol pill had 80 percent fewer brain lesions - the telltale sign of the disease.

The problem is, it's not available in the United States yet -only Europe.

Doctors are conducting a larger study to change that.

"Our goal is to acquire data, based on efficacy in MS and safety," says Dr. Voskuhl. "To go to the FDA, and say- what else do you need? What can we do to try and get FDA approval to bring estriol to the United States?"

Most M-S drugs are injected - and can cost up to 20-thousand dollars a year.

Estriol is a pill, and much cheaper.

Dr. Voskuhl says, "It's generic. It'd be on the order of 70 dollars a year."

Trials on the hormone are still recruiting patients, and the University of Pennsylvania is one of the study sites.
