Patients with mild to moderate persistent asthma and/or rhinitis
according to the Global Initiative for Asthma guidelines [12],
monosensitized to HDM, who had been followed in the
outpatient clinic for at least 2 years without improvement
with inhaled corticosteroid treatment, were recruited and
randomized to receive SCIT, SLIT, or pharmacotherapy only
(control group). The inclusion and exclusion criteria applied
during randomization have been previously reported [13].
The study protocol was approved by the ethics committee at
our center (approval number B.30.2.MAR.0.01.02/AEK/707),
and written consent was obtained from the parents of all the
children included.
