Introduction and objectives. The study aimed at evaluating the impact of Hymenoptera venom allergy (HVA) in children and adolescents, on their parents' QoL, taking into account their socio-demographic characteristics. Materials and method. The study sample consisted of 101 parents of children and adolescents aged 9-17 years, with a history of systemic reaction after insect sting who were referred for consultations in the tertiary level allergology department. The mean age of the parents was 39 years (SD=8.1; range 25-65 years); the majority were mothers (68%) and rural inhabitants (62%). QoL in parents of HVA children and adolescents was measured with the Parents of Children with Hymenoptera Venom Allergy Quality of Life Scale, a questionnaire covering 5 dimensions: anxiety, caution, limitations and discomfort, support provided to the child and feeling of safety, each measured on the scale ranging from 1 to 5. Independent predictors of QoL were estimated using the Generalized Linear Model. Results. Parents of urban children and adolescents treated with venom immunotherapy (VIT) up to 3 years (B=-1.37, 95CI= (-2.22;-0.53); p=0.001) and of rural children treated for more than 3 years (B=-0.94, 95CI=(-1.55;-0.33); p=0.003) reported lower anxiety than parents studied at diagnosis. In urban parents, individuals studied at VIT beginning reported a lower feeling of safety (B=-0.63, 95CI=(-1.11;-0.15); p=0.010); those studied up to 3 years of treatment reported a higher feeling of safety (B=0.64, 95CI=(0.11;1.16); p=0.018) than those studied at diagnosis. Contrariwise, in rural parents, those studied at the beginning of immunotherapy reported a higher feeling of safety than those studied at diagnosis (B=0.51, 95CI=(0.13;0.88); p=0.008). Conclusions. The longest VIT duration in children and adolescents with HVA is related to the decreased anxiety of their parents. Parent's feeling of safety depends on the stage of treatment and place of residence.

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. Materials and method. 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.
