Dear Doctor: Could you explain Guillain-Barre syndrome? My 57-year-old niece died of it, but it's still a mystery to me.

Dear Reader: First, please allow me to offer my condolences for the loss of your niece. There's no way to make the loss any easier, but I will try to explain a bit more about this terrible disease.

Guillain-Barre syndrome (GBS) is an acute inflammatory attack on the nerves by the immune system. The theory is that after certain viral or bacterial infections, the immune system, in its attempt to attack the virus or bacteria, also attacks the nerve cells because their proteins are similar to the viral or bacterial proteins. As the nerves fail to work, the patient develops progressive muscle weakness and nerve dysfunction throughout the body. Each year in the United States, the syndrome is diagnosed in one or two of every 100,000 people; the risk increases as we get older.

Infections with the intestinal bacteria Campylobacter jejuni have been known to increase the chances of GBS, with one study finding that three out of 1,000 patients infected with Campylobacter jejuni develop GBS. The bacterium is found in contaminated, undercooked poultry and meat, but also unpasteurized milk. Infection with HIV, influenza virus, Epstein Barr virus and cytomegalovirus also have been linked to a higher risk of GBS.

The influenza vaccine may slightly increase the chance of developing GBS. Specifically, about one out of a million people vaccinated against the flu develop the condition, although the rates are a bit higher with the H1N1 influenza vaccine -- about two in a million. Note that this is far lower than the number of people who die from the flu -- 1.4 per 100,000 -- and the number of people who develop GBS after the vaccine is actually lower than the number of unvaccinated people who develop it. The meningitis vaccine Menactra also has been linked to GBS in those ages 11 to 19, but the level of risk is still under investigation.

GBS manifests in many different ways, but symptoms generally begin with back pain and a feeling of tightness and tingling in the lower legs. One or two days later, weakness develops in the legs -- so much so that getting up from a chair or walking up the stairs can be difficult. Weakness then can develop in the mouth, throat and face, causing difficulty talking and eating. Weakness can also develop in the eyes, causing altered vision.

When the muscles used to breathe are involved, progressive shortness of breath develops, with 9.1 percent of patients hospitalized for GBS needing a respirator. In 70 percent of patients, GBS can also affect the nerves that go to the heart, blood vessels, bladder and the intestines, leading to abnormal heart, bowel and bladder function.

Without treatment, 67 percent of people with GBS will start to recover after four weeks. The recovery may be slow and incomplete depending on the severity of the illness. The use of plasmapheresis, which filters antibodies from the blood, can speed improvement, as can intravenous immunoglobulin. Even with these treatments, the death rate of those hospitalized with GBS is 2.58 percent.

Again, I'm sorry to hear about the passing of your niece. Better treatments are so obviously needed.

Treatments for Rheumatoid Arthritis Unique to Individual Patient

Dear Doctor: We were shocked when our daughter, who is 26, was diagnosed with rheumatoid arthritis. I thought arthritis was something that elderly people got. What treatments are available, and what are our daughter's prospects for an active and healthy life?

Dear Reader: We're very sorry to hear about the medical challenge your family is facing and hope the information we offer will be of help.

When it comes to what is commonly referred to as "arthritis," we're actually talking about two different conditions. Osteoarthritis, which is the type of arthritis you're thinking of in regards to a more elderly population, is a degenerative disease. In osteoarthritis, the tissues of the joints deteriorate due to wear and tear. When the cartilage that cushions the joints begins to break down, it leads to swelling, stiffness and pain.

Rheumatoid arthritis, or RA, is an inflammatory autoimmune disease. Joint damage occurs because the immune system has gone haywire and begins to target the body's own tissues. Although RA most commonly affects the joints, it can also involve other parts of the body, including the lungs, digestive system, circulatory system, skin and eyes.

In the United States, about 1.5 million people (more women than men) are living with RA. It generally doesn't appear until the 40s, and becomes increasingly common as we hit our 50s and beyond, but cases in younger people are not rare.

The most common sites of inflammation in RA are the wrists and the finger joints closest to the palm. However, the knees, neck, ankles, feet, elbows and shoulders can also be involved. RA has a symmetrical pattern, so the joint on each side of the body is usually affected. In addition to that symmetry, symptoms of RA include tender and swollen joints, a feeling of warmth within the joints, fatigue and occasional fever. For many people, prolonged morning stiffness or difficulty moving again following a long period of inactivity can be some of the early signs of RA.

Treatment is tailored to each person's symptoms. Your daughter's rheumatologist will discuss lifestyle changes to address inflammation. This includes using special tools or aids to help with difficult tasks, pursuing the right kind of exercise -- hatha yoga has been found to be helpful -- and striking the optimal balance between activity and rest.

Eating a well-balanced anti-inflammatory diet can help manage RA symptoms. This treatment approach got a boost recently when a study found that RA patients who ate fish twice a week (baked, steamed, raw or broiled, but not fried) scored measurably lower on a standardized scale that measures disease activity.

Some medications for RA address pain and inflammation. Others take aim at the disease process itself. All have potential side effects, so urge your daughter to learn the risks and benefits of any proposed medication.

Looking to the future, advances in immunotherapy and the expanding study of the ever-surprising gut biome offer hope for RA sufferers. In the meantime, prompt treatment is crucial. Make sure your daughter finds a good rheumatologist she likes and begins her medical care.

Recent Study Suggests Possible Link Between Stroke and Diet Soda

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Ask the Doctors | August 21st, 2017

Dear Doctor: A recent news report said that diet sodas may be tied to stroke or dementia risk, but it didn't provide a possible cause. What's your take?

Dear Reader: You're referring to a 2017 study published in the journal Stroke. The study followed two groups of people: one over age 45 (2,888 people) and one over age 60 (1,484 people). The participants filled out food questionnaires three times: between 1991 and 1995, between 1995 and 1998, and between 1998 and 2001. Participants were asked about the type and frequency of their beverage intake. The groups of beverages included sugar-sweetened soft drinks, fruit juice, sugar-sweetened fruit drinks and artificially sweetened soft drinks. After the last questionnaire, researchers assessed the rates of stroke and dementia in the subsequent 10-year period.

People who drank artificially sweetened soft drinks one to six times per week had a 59 percent increased risk of stroke compared to those who did not drink artificially sweetened soft drinks. This rate increased to 79 percent among people who drank one or more of these drinks per day. The rate was even higher among people who reported this higher use most recently (between the years 1998 and 2001).

In regards to dementia, people who drank artificially sweetened soft drinks one to six times per week had a 30 percent increased risk of dementia compared to those who drank no artificially sweetened soft drinks, while people who drank one or more per day had a 70 percent increased risk.

These numbers seem significant, but the study's many confounding factors decrease their strength. For one, the number of people suffering strokes or developing dementia was limited, making it difficult to draw overarching conclusions.

Also, consider that -- according to the data -- people who drank sugar-sweetened soft drinks more than three times per week actually had a 20 percent reduction in the risk of strokes compared with those who drank none -- and a 23 percent decreased risk of dementia. My kids might disagree, but I really don't think that a greater number of sugar-sweetened soft drinks would be good for you.

Further, even before the study began, 22 percent of those who drank artificially sweetened sodas had diabetes, while 7 percent who didn't drink them had diabetes. Diabetes itself is a risk factor for both stroke and dementia, so the increased risk found in the study may have nothing to do with the sodas. The authors said they adjusted for this, but with such small numbers, that's difficult to do.

Don't get me wrong: Artificially sweetened sodas are certainly not healthy. They trick the brain and the body into believing it has had something sweet and thus may cause a greater overall craving for sweet foods or drinks. A 2012 evaluation of two large studies with 127,456 people found a 12 percent increased risk of stroke among people who drank one or more sugar drinks per day -- and a 9 percent increased risk of stroke among people who drank one or more artificially sweetened drinks per day. These results were more significant than the current study due to the large population of people involved.

So while there may be a link between diet sodas and stroke, it doesn't seem to be to the degree that this news report suggested.
