Scientists claim to have found the root cause of asthma which could also aid in the treatment of other respiratory diseases like COPD. This breakthrough could mean that there could be a new treatment within 5 years.
They have found a protein within the airways which they believe triggers an asthma attack. Asthmatics seem to have higher levels of this protein and when they breathe in a trigger such as dust or pollen these protein molecules cause a rapid increase of calcium within lung tissue cells. High levels of calcium within these cells make them contract and cause the airway spasms which trigger an asthma attack.
The presence of this protein makes cells more sensitive to any asthma triggers, which then makes an attack much more likely.
A drug already exists which can deactivate the protein and clinical trials could start within 2 years, raising hope that a treatment could be available within 5 years.
It is hoped that a few courses of treatment would be enough to stop asthma attacks. Not only this but there is hope that it may have a role in tackling COPD and chronic bronchitis for which there is currently no treatment. Hopefully at a minimum it may prevent flare-ups for these patients and make them less susceptible to the triggers such as dust, smoke and pollen, which can stimulate a severe respiratory event. This could help COPD sufferers enjoy fewer flare-ups and less respiratory distress improving their ability to lead more normal lives.
