  1. Prevalence of atopy in students from Málaga, Spain.

    Article - En anglais

    Background 

    Epidemiologic studies are necessary to determine the prevalence of allergic diseases.

    This varies widely depending on allergen preparations and patients studied.

    Objective 

    To investigate the prevalence of atopic disease, skin test reactivity, total and specific IgE to common allergens and other variables in a sample of students from Málaga. southern Spain.

    Methods 

    Three hundred sixty-five students (age 17.9 ± 1.18) were interviewed by an allergist.

    Skin prick tests were performed with Dermatophagoides pteronyssinus, Artemisia vulgaris, Plantago lanceolata, Chenopodium album, Olea europaea, Phleum pratense, Parietaria judaica, Cynodon dactylon, Alternaria tenuis, and cat dander.

    Total and specific IgE to D. pteronyssinus, Olea, and Parietaria were determined.

    Results 

    Of all subjects studied, 19.9% suffered from rhinoconjunctivitis, 4.1% rhinoconjunctivitis plus asthma. 3.1% asthma alone, and 0.8% atopic dermatitis : 46.4% had a positive skin test to at least one allergen (28.2% to D. pteronyssinus, 20.4% to Olea, 13.8% to Phleum) : and 43% had total IgE>100kU/L and 44.7% a family history of atopy.

    Allergic symptoms were strongly associated with skin test positivities and family allergic history.

    Patients with asthma or skin prick test positive had higher total IgE values than others (P<. 01).

    There was a significant correlation between specific IgE values and wheal size in skin test. (...)
