Does early steroid therapy prevent permanent airway damage in asthma?:
There is little doubt about the inflammatory nature of asthma, which involves
chronic eosinophilic inflammation of the airway and activation of myofibroblasts
in the underlying lamina reticularis. Ultimately the result of all this
is airway remodelling associated with increasingly-irreversible airflow
obstruction and a decline in lung function. However, what has not been
resolved is whether earlier intervention with steroid treatment will prevent
the permanent lung damage. Only a large-scale randomised study against
a placebo will resolve this issue, meanwhile there are single-centre studies
which have shown results going in both directions (i.e. steroids do appear
to prevent damage in some studies but not in all), and in a recent report
in the Lancet there were clearly benefits/advantages in the group treated
on budesonide vs placebo.
