Meningitis research targets teenagers
Stress may make teenagers more susceptible to meningitis
Scientists are to study why teenagers are susceptible to the potentially fatal brain disease meningitis.
Three teenagers have died in the last week following two outbreaks of the disease in South Yorkshire and Tyneside. A third teenager is reported to be in a stable condition in hospital in Rotherham.
One of the main theories that will be studied is the idea that stress increases susceptibility to contracting the disease.
Dr Robert Booy, a lecturer in paediatrics at St Mary's Hospital, London, said previous studies had concentrated on young children and not teenagers.
"We will be looking at things like their social behaviours, like smoking, like kissing, going to parties. We are looking at the stresses they undergo like the psychological factors of leaving home and going to university.
"We will also be looking at biological factors."
Teenage years are stressful
He said: "It is an extremely stressful time. Relationships start and sometimes abruptly finish."
Dr Booy said previous research had suggested that stress was a factor in increased susceptibility.
Approximately 50% of cases of meningococcal meningitis occur in children under five. There is then a trough before an upsurge of cases in adolescents aged 15 to 19.
The researchers will look at two groups of teenagers, one affected by meningococcal disease and the other group not affected.
Blood samples will be collected from teenagers admitted to hospital with meningococcal disease and from a healthy person of the same sex and age, selected as a control who is registered with the same GP as the patient.
Dr Booy said teenagers should look out for each other. If a friend had 'flu symptoms they should be closely monitored.
The key thing to look out for is a characteristic rash of small red or purple spots.
