Abstract

The presence of immunoglobulins to Malassezia spp. surface proteins in the sera from patients with atopic dermatitis and healthy subjects was studied. It was found that 28% of 25 examined patients with atopic dermatitis had IgE antibodies to Malassezia spp. surface protein preparation. All patients and 5 healthy subjects had IgG antibodies to this preparation. The presence and concentration of specific IgE antibodies in patients with atopic dermatitis correlated with reverse titers of IgG antibodies to this preparation (r=0.782). The medians of values reciprocal to IgG antibody titers in patients with atopic dermatitis with and without specific IgE antibodies to the preparation and in healthy subjects were 64, 1024, and 16, respectively. The preparation derived from Candida albicans (candidine) and previously derived preparation from Malassezia did not cross-react. According to immunoblotting data, the preparation contains allergens presented by proteins with molecular weights 15, 36, 52-56, and 78.4 kDa.
