  1. Prevalence of allergic sensitization to inhalant allergens among blood donors in Kuwait : a desert country.

    Article - En anglais

    Kuwait is a desert country where the prevailing high temperatures, low humidity, and scant vegetation suggest a low prevalence of allergy.

    We evaluated the prevalence of atopic sensitization (presence of allergen-specific IgE) among young adult blood donors by screening a total of 505 subjects (male : female ratio 1.6) with mean age of 28.4 years (range 18-50 years).

    The Pharmacia CAP-Phadiatop test, which detects serum IgE specific to most common airborne allergens, was used.

    Some of the specific sensitizing allergens were also identified by the related CAP-RAST method.

    Sensitization was detected in 223 of the 505 subjects (44.2%) screened.

    Kuwaiti nationals had a significantly higher prevalence rate (50.2%) than non-Kuwaitis (34.2%) (X2=8.6, P<0.003).

    The highest prevalence rate was found among male Kuwaitis (53.8%). The prevalence of current or previous allergic disease (subject-reported) was 20.6%. Bermuda grass, house-dust mite (Dermatophagoides pteronyssinus), and Chenopodium album were the most prevalent sensitizing allergens, with frequencies of 53.6%, 52.7%, and 50.9%, respectively, among the sensitized subjects (corresponding to 23.7%, 23.3%, and 22.5%, respectively) for the entire population.

    Sensitization increased with age, but only among the expatriates, younger Kuwaitis being as frequently sensitized as the older ones.

    Polysensitization was found to be common. (...)
