  1. Fulltext. Eosinophilia and positive skin tests predict cardiovascular mortality in a general population sample followed for 30 years.

    Article - En anglais


    The authors investigated whether two objective allergy markers, peripheral blood eosinophilia and skin tests for common aeroallergens, were associated with cardiovascular death.

    Of 5,382 subjects in the Vlagtwedde-Vlaardingen Study (the Netherlands) with data on allergy markers in 1965-1972,507 subjects died from cardiovascular disease during 30 years of follow-up.

    Subjects with eosinophilia had an increased risk of cardiovascular death (relative risk (RR)=1.7 ; 95% confidence interval (Cl) : 1.4,2.2), including ischemic heart disease death (RR=1.6 ; 95% Cl : 1.2,2.2) and cerebrovascular death (RR=2.3 ; 95% Cl : 1.4,3.8), independent of major risk factors.

    This association was limited to subjects with a percentage of the predicted forced expiratory volume in 1 second (FEV1% predicted) of<100%. Positive skin tests were associated with a significantly reduced cardiovascular mortality in subjects with normal lung function and weight who did not smoke (RR=0.15 ; 95% Cl : 0.05,0.46).

    Conversely, when subjects with positive skin tests had a body mass index of >=25 kg/m2, had an FEV1% predicted of<80%, or smoked, they had an increased risk for cardiovascular mortality.

    These results were not restricted to asthmatics.

    Our data suggest a possible link between eosinophilia and positive skin tests and cardiovascular mortality, especially in combination with other risk factors associated with its mortality.
