Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. sublingual immunotherapy (SLIT)+standard pharmacotherapy (SP)
patients receive SLIT as 5 sublingual droplets three times a week for 3 years (Dermatophagoides pteronyssinus and pharinea %50 mix) after following an induction phase for 1 month of slowly increasing dosing schedule reaching the maintenance dose mentioned above with the same preparation
1st dose is supervised by the physician and the rest is ingested by patient at home

2. subcutaneous immunotherapy (SCIT)+standard pharmacotherapy
SCIT is received by subcutaneous injection at the hospital by the physician once a month for 3 years (Dermatophagoides pteronyssinus and pharinea %50 mix) following a weekly injection (for 3 months) of increasing doses of allergen.
a)starting dose of SCIT 0.1 ml of 100u/ml b) maintenance dose of SCIT 1 ml of 100000u/ml of allegen injected
every child is supervised by a physician following the injection for half an hour
Intervention code [1] 284893 0
Treatment: Drugs
Comparator / control treatment
standard pharmacotherapy

inhaled fluticasone is administered (125 mcg) twice a day by aerospacer and puffs. Dose adjustment is made by symptom severity and disease control
