The relationship between serum selenium levels and frequent wheeze in children.

and had had no infectious disease for two months and an equal number of age- and sex-matched children, as a control group, without atopy or allergy or systemic diseases were enrolled in the study. In the study group, we determined the levels of serum selenium, total IgE, mixed specific IgE, and total eosinophil count, and we performed epidermal prick tests. Serum selenium levels were (mean and SEM) 61.95±1.23 µg/L in the study group and 72.71±1.28 µg/L in the control group (p<0.001), and there was a negative correlation between the serum selenium levels and number of wheeze attacks during the previous year (r= -0.655; p<0.001).
