A type of
medication that is normally used by asthma sufferers has been proving
stunningly effective in treating a form or paralysis – and has even
allowed a wheelchair-bound teenager to walk unaided for the first time
in seven years.
Jimmy
Webster, 18, took salbutamol to treat congenital myasthenia. He had
been so disabled he sometimes needed an oxygen-mask to breathe.
But
he says: ‘Within three days I could stand and within a week I could
walk.’ Now he is about to go camping and adds: ‘I wouldn’t have
contemplated this last year.’
Salbutamol
is prescribed to asthmatics in inhaler form under the brand name
Ventolin. It is now proving a remarkable treatment for myasthenia, which
affects 12,000 Britons and can cause symptoms ranging from a mild
drooping of the eyelids to full-blown paralysis.
The
drug is a beta-2-agonist, a class of compounds that affect the nerve
communications in the muscles. It was already known that a similar drug,
ephedrine – a stimulant also found in cold and flu remedies, and in
higher doses in dangerous ‘fat-burning’ diet pills – was sometimes
effective in treating myasthenia.
Studies
had shown widespread benefits, with another teenage patient going from
needing crutches to walk, to jogging and doing sit-ups.
So
Professor David Beeson at the Weatherall Institute, of Molecular
Medicine, Oxford University, looked for other drugs which may work as
well or better. One of these was salbutamol.
Myasthenia
is either congenital – due to a genetic mutation – or caused by the
immune system turning inward and attacking the body, developing later in
life.
The
congenital condition is noticeable from birth but the problem with
treating it is that it is caused by different genetic mutations, which
need different drug combinations. Prof Beeson explains: ‘Our research is
devoted to working out what drugs best treat each one.’
Salbutamol
can be used alone or with other drugs. Prof Beeson adds: ‘It is not yet
licensed for use in the condition, but clinicians are happy to
prescribe it.’
He suggested that Jimmy try salbutamol alongside pyridostigmine, a standard drug which he had been taking since he was four.
‘I
expected I’d get stronger, but had no idea I’d be able to walk again,’
says Jimmy, from Cardiff, who is awaiting A-level results before
hopefully going to study Economics at Oxford University.
‘I
still use my wheelchair out and about, but at home I walk around – just
getting dressed, washing and cooking, it’s amazing to be able to normal
things.’
Prof
Beeson says: ‘It is incredibly rewarding to see results like this. Over
the last couple of years we have seen patients rise from their
wheelchairs within months, but Jimmy’s quite exceptional.’
