What is the link between febrile seizures
in childhood and epilepsy later in life?
About 5% of all children under the age
of five years will experience at some point
a seizure caused by a fever. These are called
febrile seizures. These seizures are not
normally serious, and go away when the fever
subsides. However, if these seizures are
long or occur frequently, developing temporal
lobe epilepsy (TLE) in adulthood is more
likely. This form of epilepsy is often not
treatable with current anti-epileptic drugs.
Scientists think that the febrile seizures
may cause some sort of damage to the brain
cells in the hippocampus, and that this
is then the cause of the seizures many years
later. These developments may be linked
by the activity of a protein called interleukin-1,
which is part of the body's immune system.
Interleukin-1 helps generate and regulate
the body's immune response. Developing a
fever is also part of this natural immune
response.
Dr Stuart Allan at the University
of Manchester has been awarded £59,518
over three years to investigate this link.
This project, called "The association
between febrile seizures and temporal lobe
epilepsy and the role of interleukin-1",
will look for the link by studying interleukin-1
levels and distribution in the brain. Dr
Allan will look at whether these levels
can be affected by genetic background or
by the administration of anti-inflammatory
drugs. If interleukin-1 is proved to be
part of the development of TLE from febrile
seizures, this may provide the basis for
a new treatment for febrile seizures in
children which will reduce their chances
of getting TLE later in life.
UK-wide survey of refractory convulsive
status epilepticus in children
Most seizures end naturally after just
a few seconds or minutes. Occasionally,
they can last much longer, as much as 30
minutes or more. These seizures are then
called status epilepticus. A very long tonic-clonic
seizure is called convulsive status epilepticus.
This can be treated, but sometimes the drugs
do not work and the status continues. This
is then called "Refractory convulsive
status epilepticus" (RCSE). This
is a serious medical emergency and, particularly
in children, may cause brain damage or death.
The treatment of RCSE is therefore very
important. There is currently no agreement
amongst doctors on which drugs and treatments
should be used to treat RCSE.
The sum of £6,657 has been
awarded to Dr Richard Appleton of
the Roald Dahl EEG Unit, Royal Liverpool
Children's Hospital, and his colleagues,
to carry out a national audit of RCSE in
the UK. This study will look at all children
admitted to intensive care with RCSE over
the course of one year. The researchers
will study how many children get RCSE, what
caused each case, what treatment was given
in hospital and what happened to the patients
afterwards. This will indicate which treatments
are the safest and most effective, and could
lead to a trial comparing them. It will
also be used to find new and improved treatments
for RCSE. It is hoped that this work will
ensure fewer children suffer brain damage
or death because of RCSE.
