They reviewed nine studies including 441 patients between 3 to 18 years conducted with the help of sublingual immunotherapy (SLIT) for allergic asthma in children. SLIT involved the oral administration of allergen exacts, either through soluble tablets or drops. The findings revealed that SLIT diminished both the symptom scores and rescue medication use in children with allergic asthma compared with placebo. Moreover, the side effects were mild and self-resolving. They suggested that SLIT is clinically effective in asthma in children though further studies are required to determine the effective dose and regime. This study is published in the March issue of the journal Chest.
