STORY BYIt starts off like the flu. But in a matter of hours, meningococcal meningitis can turn deadly. The party/study-all-night, no-sleep, communal lifestyle of college students puts them at particular risk for the fast-moving disease.
This year, college students can protect themselves with a meningitis shot before they go back to school. The Centers for Disease Control and Prevention (CDC) now recommends routine vaccination of college freshmen living in dormitories with the newly licensed meningococcal conjugate vaccine (MCV4). The vaccine is also recommended for children 11-12 years old and previously unvaccinated adolescents who are entering high school.
The new vaccine protects against meningococcal meningitis, one strain of several types of bacterial meningitis.
Meningitis is an infection of the linings of the brain and spinal cord, caused by a virus or bacteria. Viral meningitis (the kind that Brad Pitt had) is usually less serious, and goes away on its own.
But bacterial meningitis progresses quickly and can kill within hours. Many young adults think they have a cold or the flu. They treat themselves with over-the-counter medicines and wait to get better, wasting critical time.
These symptoms can develop over several
hours, or they may take 1 to 2 days. As the
disease progresses, patients may also have
seizures. For more information about
meningitis, visit the Center for Disease
Control’s website at http://www.cdc.gov
If caught soon enough, the infection can be treated with targeted antibiotics. Still, up to 15 percent of people who contract meningococcal meningitis may suffer long-term permanent disabilities including hearing loss, limb amputation or brain damage. And 10 to 12 percent of people with meningococcal meningitis die, according to the CDC.
“This is the type of meningitis that you do not want to have because the death rate is so high,” says Dr. Lynnette Mazur, professor of pediatrics at The University of Texas Medical School at Houston. “It moves very quickly. In my career, I have only seen one person who survived intact, and that’s because she got treated immediately. We had Life Flight (an air ambulance) pick her up.”
Several different strains of bacteria can cause meningitis. Today, Streptococcus pneumoniae and Neisseria meningitidis are the leading causes of bacterial meningitis. H. influenzae type b used to be a leading cause of meningitis, but now infants are routinely vaccinated against the bacteria.
“Since the HIB vaccination came out in the mid-80s, I haven’t seen any cases (of meningitis) caused by it,” Mazur says. “It is amazing.”
Doctors hope the new meningococcal meningitis vaccine might cause similar "herd immunity" in adolescents, as the HIB vaccine has in infants. Using the theory of herd immunity, if 90 percent of people are vaccinated, the remaining unvaccinated 10 percent would also be protected from infection.
The MCV4 vaccine is administered in the arm in a single shot. Side effects from the shot are usually mild, but may include some swelling at the injection site. Unlike previous meningitis vaccines, the new vaccine is boostable. About three years after getting the shot, patients can receive another one to “boost” its effectiveness.
Because they were not boostable, previous versions of meningitis vaccines were given sparingly – usually only during meningitis outbreaks and to people in close contact with a person infected with meningitis. The vaccine provided immediate protection against meningitis. But should an outbreak occur in the future, the recipient of the vaccination could not be vaccinated again. Theoretically, they would have little protection against meningitis.
At this writing, Mazur says she is still waiting on her supply of the new vaccine, but expects it soon. Some private clinics are beginning to offer the vaccine. Mazur recommends teens and college-age adults put the meningitis shot on their back-to-school list.
“I definitely agree with the recommendation for vaccination,” Mazur says. “This is a bad strain of meningitis, and there’s not much that kids can do to prevent it.”
The MCV4 vaccine does not protect people against meningococcal disease caused by serogroup B bacteria. This serogroup of bacteria causes one-third of meningococcal cases in the United States.
In addition to getting a meningitis shot, what can young adults do to reduce their risk for the disease?
“Stop smoking, go to bed on time, eat right and don’t drink as much,” Mazur says, adding that most college kids won’t follow her prescription for clean living.
Fortunately, meningococcal meningitis isn’t as contagious as the cold or flu. People can’t get it by breathing the air. The bacterium that causes meningococcal meningitis is transmitted through the exchange of nasal and throat secretions from kissing, coughing and sharing drinking glasses. To reduce their risk, young adults should wash their hands frequently and try not to eat or drink after others.
Cutting back on partying also helps reduce risk for meningitis. Going to bars and nightclubs, and drinking alcohol have been associated with greater risk for meningitis.
“There is just something special about teenagers (and young adults),” Mazur says. “They don’t sleep right, they depress their immune system. They make conditions ideal for acquiring meningitis.”

Eating healthy
reverses metabolic syndrome
Dr. Tasnime Akbaraly of University College London and her colleagues were interested if healthy eating could actually turn-the-tide and reverse metabolic syndrome, which is having 3 or more of the following risk factors: excess abdominal fat; high triglycerides, hypertension, low levels of HDL the “good” cholesterol, or type 2 diabetes. Having metabolic syndrome doubles a persons’ risk of heart disease and greatly increases the odds of developing type 2 diabetes.
The researchers studied 339 British civil servants with metabolic syndrome, and how closely the adhered to the Alternative Healthy Eating Index (AHEI) to see if it could help reverse metabolic syndrome. The AHEI is a set of published nutritional guidelines by the Harvard School of Public Health in 2002 that emphasizes whole grains, fruits, vegetables and decreased red meat consumption.
Five years into the study, nearly 50% no longer had metabolic syndrome. People who followed the AHEI guidelines the closest were nearly twice as likely to have reversed their metabolic syndrome. The results of the study were published in Diabetes Care, online July 29, 2010.
Dr. Alice Lichtenstein, an expert on diet and heart health from Tufts University in Boston who was not involved in the study said, "It's not about focusing on individual components of the diet, it's really the whole package, and that becomes important because it means that if one of the components of a healthy diet is to eat more fruits and vegetables, just buying a pill saying that there's a concentrated extract of fruits and vegetables is probably not what's going to help you."
