Health-related quality of life in children and adolescents after systemic sting reaction

Abstract

Introduction and objectives: Insect stings are the second trigger of anaphylaxis in children and adolescents, causing a potentially life-threatening reactions. Hence health-related quality of life (HRQoL) is an important issue for Hymenoptera venom allergy (HVA) patients. The aim of this cross-sectional study was to evaluate the impact of HVA on young patients' HRQoL, including their socio-demographic characteristics.

Material and methods: The study sample included 102 patients aged 8-17 (Mean 12.5 years, SD=3.0), who were under diagnosis or venom immunotherapy due to systemic reaction after an insect sting in one of the tertiary referential centers in Poland. They were mostly boys (70%), and mainly from rural areas (63%). HRQoL of studied patients was measured with the Children's Hymenoptera Venom Allergy Quality of Life Scale, a questionnaire covering 6 dimensions: anxiety, caution, limitations, discomfort, support received from parents and a feeling of safety, each measured from 1 to 5. Independent predictors of HRQoL were estimated using the Generalized Linear Model.

Results: In the group of children being dermal reactors, girls reported a higher level of anxiety (B=1.17, 95%CI=(0.30;2.03), p=0.008). In the group of children with grade 2 it was the girls who reported lower anxiety (B=-1.33, 95%CI=(-2.38;-0.29), p=0.013). Boys treated longer than 3 years had their level of anxiety significantly lower than those studied at diagnosis (B=-0.65, 95%CI=(-1.23;-0.07), p=0.028). The feeling of safety was higher in children living in villages than in those living in towns (B=0.30, 95%CI=(0.03;0.56), p=0.031).

Conclusions: The gender, treatment duration and stage of anaphylactic reaction influenced level of anxiety. The level of feeling of safety was related to the place of living.
