Background:
To evaluate the clinical efficacy of sublingual-specific immunotherapy (SLIT) and pulmonary function in children with allergic rhinitis and asthma before and after puberty.
Methods:
This retrospective analysis included 136 patients aged 4-18 years with allergic asthma and rhinitis who received two years of SLIT treatment. Patients were divided into two groups based on age: the prepubertal group (4-10 years old) and the pubertal group (11-18 years old). After half a year, one year, and two years of SLIT, the total nasal symptom score (TNSS), total rhinitis medication score (TRMS), daytime asthma symptom score (DASS), nighttime asthma symptom score (NASS), total asthma medication score (TAMS), asthma control test (ACT), and peak expiratory flow rate (PEF%) were evaluated and compared with the baseline before treatment.
Results:
In both groups, TNSS, TRMS, DASS, NASS, TAMS, ACT, and PEF% improved significantly after half a year, one year, and two years of SLIT treatment. After half a year of treatment, prepubertal patients showed better therapy for TNSS, DASS, NASS, and TAMS compared to the pubertal group. The TAMS of the pubertal group was higher than that of the prepubertal group after one year of treatment. Finally, the PEF% showed better therapy compared to the pubertal group.
Conclusion:
SLIT treatment with Dermatophagoides farinae drops can effectively control the symptoms of rhinitis and asthma in children with allergic rhinitis and asthma before and after puberty, reduce the use of symptomatic drugs, significantly improve the pulmonary function of patients, and have better effects on asthma in prepubertal children than in adolescents.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
