Standardized Quantitative Evaluation of Clinical Effectiveness and Side Effect Profile of Subcutaneous and Sublingual Allergen-Specific Immunotherapy in Children: A 5-Year Single Center Experience

Objective: Allergen-specific immunotherapy (allergen-SIT) is a treatment method with variable efficacy in allergic diseases. This study aimed to investigate the effectiveness of allergen immunotherapy, frequency of LRs and SRs and variables affecting these parameters in patients who underwent allergen-SIT. Materials and Methods: In this study, the recorded data of 81 patients, who received subcutaneous (SCIT) or sublingual (SLIT) allergen immunotherapy for respiratory allergic diseases between 2014 and 2019, were analyzed. In asthma and/or allergic rhinoconjunctivitis (ARC) patients, the effectiveness of treatment was evaluated by analysing the change rates in disease symptom, medication and combined scores (symptom + medication) and visual analog score (VAS). Treatment success was defined by the degree of decrease in scores as; high response above 50%; low response between 20-50%; and failure
