Obese girls are at greater risk of developing multiple sclerosis or MS-like illness, according to a new study published Wednesday in the online journal Neurology.
Researchers looked at body mass index (BMI) data from more than 900,000 children from the Kaiser Permanente Southern California Children's health study. Seventy-five of those children and adolescents between the ages of 2 and 18 were diagnosed with pediatric MS. More than 50% of them were overweight or obese, and the majority were girls.
According to the study, the MS risk was more than one and a half times higher for overweight girls, almost two times higher in moderately obese girls and almost four times higher in extremely obese girls.

Shingles is a painful but common condition, affecting half of Americans by age 85. All adults aged 60 and older should receive a vaccine against it, according to the CDC's Advisory Committee on Immunization Practices.
But not everyone is eligible for this preventive measure. The vaccine is not recommended for people being treated with immune-suppressing drugs called “biologics,” which control how the body reacts to inflammation in a variety of conditions such as rheumatoid arthritis and psoriasis.
Contrary to that advice, a new study found no increased risk for shingles among people with rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, or inflammatory bowel disease who have been treated with biologic medicines and receive the shingles vaccine. The study is published in the Journal of the American Medical Association.

Kim Kardashian learned she has psoriasis in an episode of “Keeping Up with the Kardashians” that aired Sunday.
Alarmed after finding red, itchy patches on her legs, Kardashian heads to the dermatologist. Dr. Harold Lancer takes one look at the scaly rash and determines she has psoriasis, a common skin disease that causes skin to dry and form itchy spots.
The severity of psoriasis depends on the person – some people can be covered in these patches; other cases can be associated with arthritis. For others, it’s just a small nuisance.
“I cannot have psoriasis,” Kardashian tells her dermatologist on the show. FULL POST

The Food and Drug Administration on Wednesday approved the drug Benlysta (belimumab) for the treatment of lupus, a chronic, potentially fatal autoimmune disease that affects about 5 million people across the world and, specifically, about 1.5 million Americans.
“This is a historic day for the millions of people with lupus and their families around the world who have waited more than 52 years for a treatment breakthrough for lupus," said Sandra C. Raymond, president and chief executive officer of the Lupus Foundation of America, in a statement. "Today marks the beginning of a new era of improved diagnosis, prevention, and treatment for the disease." FULL POST

The rate of celiac disease is growing and the onset of gluten intolerance can occur in older people, a study in the Annals of Medicine found.
Celiac disease is an autoimmune disorder, triggered by eating the protein gluten, which is found in bread, pasta, cookies, pizza crust and many other foods containing wheat, barley or rye. People with celiac disease cannot tolerate foods containing gluten and can experience an immune reaction in their small intestines, causing damage and other complications.
Researchers from the Center for Celiac Research at the University of Maryland School of Medicine and their colleagues found that the incidence of celiac disease has doubled every 15 years since 1974 in a population sample.

Humans’ immune systems are not as different from person to person as previously thought, according to scientists at the Fred Hutchison Cancer Research Center reported Wednesday. The findings, the researchers say, could help pave the way for new drugs or immunotherapies to treat disease and infection in a host of patients, including organ transplant and skin graft recipients.
The crux of the research is the realization that of the tens of millions of T cell receptors that make up what’s known as the adaptive immune system, a small fraction of them are the same. It's called the variable region of our cells and it may not sound like a big deal but its practical applications are impressive.

Phil Mickelson is beginning his quest for the 2010 PGA championship and he's playing with the pain of psoriatic arthritis. He revealed his condition on Tuesday.
Mickelson says he experienced his first symptoms of the potentially debilitating disease five days before the U.S. Open began two months ago.
Dr. Christopher Ritchlin, professor of medicine at the University of Rochester Medical Center, says 80 percent of people who get psoriatic arthritis tend to have psoriasis first. He says patients usually have psoriasis for 10 years before also developing arthritis. Patients usually get psoriatic arthritis between the ages of 20 and 50 but children can get it too.

When I first heard about the possibility of a pill for multiple sclerosis (MS), I exlaimed, "No way!" As a person living with MS, I know that this would be a enormous advance for the MS community. The option of a pill instead of needles sounds incredible, making it so much easier for many people to stay on their therapies since currently they all involve needles. Delving into this further, I realized that several drugs in trials seemed to hold great promise, and they are not light years off.
But things aren't as simple as they first appeared.
First off, an explainer for those unfamiliar with the disease who might be curious, because chances are you know someone affected by MS. The National Multiple Sclerosis Society defines it as a "chronic, often disabling disease that attacks the central nervous system (CNS), which is made up of the brain, spinal cord, and optic nerves." The cause isn't yet known and there is no cure. What happens is the myelin - the covering of the nerves - is destroyed by the immune system. The result is scar tissue; therefore nerve impulses, or messages, are slowed down leaving people with any number of symptoms including balance, speech, vision and memory problems as well as fatigue and heat sensitivity, to name a few.
Currently, there are five potential first-line disease-modifying therapies on the market, which became available starting in the early 1990s. Four are injectibles, and vary from being given once a day to once a week. Then a few years ago, the drug Tysabri was introduced, offering a new option for people with MS as it is given intravenously once every four weeks. The choice is up to the patient and the provider.
The drugs are intended to reduce the frequency and severity of MS attacks and slow the progression of the disease. Depending on the therapy, clinical relapses can be reduced by between 1/3 and 2/3.
But the FDA has yet to approve a therapy that can be taken orally. That may soon change.
Scientists from the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) just wrapped up a meeting in Düsseldorf, Germany where they discussed this and other exciting developments in the MS community. So what does this mean for the more than 400,000 people in the U.S. - and the more than two million people worldwide –that have this debilitating neurological condition? And what does it mean for their families, friends and caregivers?
I posed that question to Dr. John Richert, Executive VP, Research & Clinical Programs of the National Multiple Sclerosis Society, who emphasized that this is a very exciting time in the MS community.
He brought back news of the emerging trends discussed at the conference:
- The first oral symptom-management drug designed to improve nerve conduction, Fampridine, is already before the FDA for review. Fampridine has been shown to improve walking speed, but may also prove to help with other symptoms of the disease (which are less easy to quantify.) Expected to follow soon are the oral disease-modifying therapies Cladribine and Fingolimod. It's important to note though, these new drugs may well carry different risks than some of the currently available options. So while the method of taking them may be easier, they will not come without their own set of possible side effects and, as Richert suggests, there will be some unchartered territory as more people take the drugs.
-Therapies with infrequent dosing (such as once a year) are being studied.
-Stem cells hold promise for new MS treatments. Of particular interest are adult bone marrow mesenchymal stem cells. According to Richert, it's a bit too early yet to know whether this approach will prove safe and beneficial, or how exactly the therapy will work.
-Within the next year or two, most of the common genes that predispose people to develop the disease will be identified. This is important not only for prevention, but for treatment as well. However, further research is needed about environmental triggers to see how genes and the environment interact to cause MS.
MS is a complicated disease and varies among individuals. What is your realistic hope for the disease and research? Now or 5-10 years down the road? We'd like to hear from you.

As a regular feature of CNNhealth.com, our team of expert doctors answers readers’ questions. Here’s a question for Dr. Gupta.
From Carolyn in Goliad, Texas:
What is the latest treatment or drug that is showing success in treating lupus?
Thanks for your question Carolyn. Lupus is a chronic autoimmune disease which seems to affect mainly women. Essentially your body’s immune system begins to attack not only foreign invaders, like viruses, but your own tissues and organs. There are four types of the disease but the most common is called systemic lupus erythematosus. Doctors don’t know the cause, but they believe it’s a combination of family history and environmental triggers. Those triggers can be something like an infection or even sunlight.
Lupus can cause inflammation in just about any organ or tissue in the body, from your skin and your lungs to your kidneys. Your doctor will determine your best treatment depending on what type of lupus you have, your signs and symptoms and their severity. This is a disease of flare-ups and periods of remissions so your medication may also change depending on what stage you’re experiencing. Plus, it can take months to nail down the most effective combination of treatments to best control your symptoms. The three most common medications are nonsteroidal anti-inflammatories, corticosteroids and antimalarial drugs.
There are currently more than 200 lupus clinical trials testing hormones, immune suppressives, stem cell transplants and biologics. But Carolyn, after getting your email we put a call into the Lupus Foundation to find out what they considered to be the most promising. They said lupus is difficult because patients with the same symptoms on the same medication can have different outcomes, so they consider targeted therapies the best hope – specifically biologics. Biologics are compounds that block or interfere with your body’s immune system response. They gave us a heads up about a large clinical trial ending in November on one such drug that they hope will help patients looking for new treatments. Granted even if this drug is shown to be beneficial it will still have to go through the FDA review process so it will be some time before it’s available in your doctor’s office.
