Article Synopsis
  • Exercise-induced bronchoconstriction (EIB) is a temporary narrowing of the airways triggered by exercise, studied in two adolescent groups: non-athletes (400) and athletes (101).
  • The research found that EIB prevalence was higher in indoor athletes (22.4%) compared to non-athletes (10.2%), with a significant difference in asthma history—6.5% of non-athletes had asthma versus 29.3% of indoor athletes.
  • Athletes demonstrated better lung function in several measurements, but EIB occurred more frequently in indoor athletes even without a prior asthma diagnosis, highlighting the need for careful evaluation of EIB in young athletes.

Microelements and vitamins are believed to have immunomodulatory effects. The aim of the study was to establish the role of antioxidants (vitamins A, E, D) and microelements such as copper (Cu), selenium (Se), and zinc (Zn) levels in allergic diseases in schoolchildren. The study uses a cohort of 80 children (40 with and 40 without allergy/asthma diagnosis) aged 9 to 12 years recruited for the Polish Mother and Child Cohort Study.

Objective: We hypothesized that, in our REPRO_PL cohort, exposure to indoor allergens and lifestyle factors in early life are associated with risk of asthma, atopic dermatitis, and allergic rhinitis at ten years of age.

Methods: We only examined children who had lived in the same house from birth. Children's exposure to tobacco smoke was assessed based on cotinine levels in urine.

Exercise may trigger bronchoconstriction, especially in a group of athletes in whom bronchospasm during exercise is reported to occur more frequently than in nonathletes. The aim of this study was to determine the prevalence and environmental risk factors contributing to exercise-induced bronchoconstriction (EIB) in adolescent athletes. A prospective study was conducted among a group of 101 adolescent athletes who underwent spirometry, exercise challenge, fractional exhaled nitric oxide (FeNO) measurements, and allergy assessment.

Objective: To specify clinical and immunological parameters of the mechanisms, which may lead to development of persistent asthma, or regression of the disease symptoms.

Methods: Eighty children with childhood asthma, diagnosed in the past by using the modified Asthma Predicted Index (mAPI), were divided into two groups: remission group and persistent group. There were 3 study visits (baseline, at 6 mo, and at 12 mo).
