Abstract
BACKGROUND: Clinical research has shown that sublingual immunotherapy (SLIT) is effective and safe in moderate-severe allergic rhinitis (AR) induced by house dust mite (HDM). However, the sample size in many studies is small. Meanwhile, the controversy on the efficacy and safety in the very young children younger than four years old still existed.
OBJECTIVE: The aim of this retrospective study is to evaluate the efficacy and safety of SLIT with Dermatophagoides farinae (Der.f) extracts in children and adult patients with allergic rhinitis, particularly in the very young children.
METHOD: A total of 573 subjects aged 3-69 with AR received a three-year course of sublingual immunotherapy with Der.f extracts along with pharmacotherapy. The total nasal symptoms score (TNSS), total medication score (TMS), visual analogue score (VAS) and adverse events (AEs) were evaluated at each visit.
RESULT: TNSS, TMS, VAS were significantly improved during the three-year course of treatment in comparison to the baseline values (P<0.01). Besides, significant improvement in nasal symptoms and reduction of medication use were also observed in young children aged 3-6 years (P<0.01). No severe systemic adverse events (AEs) were reported.
CONCLUSION: SLIT with Der.f drops is clinically effective and safe in children and adult patients with HDM-induced AR, including the very young children less than four years old.
