Atopic dermatitis of the head and neck (HNAD) is recognized as a separate condition. Malassezia, the predominant skin microbiota fungus, is considered to exacerbate atopic dermatitis (AD), especially HNAD. In the present study, we investigated the relationships between the levels of specific IgE antibodies, colonization frequency of eight predominant Malassezia species, and clinical severity in 61 patients with HNAD (26 mild, 24 moderate, and 11 severe cases). As clinical severity increased, the levels of specific IgE antibodies against eight Malassezia species also increased. Species diversity of the Malassezia microbiota in scale samples from patients was analyzed by nested PCR using species-specific primers. The clinical severity of HNAD was correlated with the total level of specific IgE antibodies against Malassezia species and the number of Malassezia species detected.

We studied the frequency of occurrence and concentration of allergen-specific IgE antibodies (asIgE) to enterotoxins A, B, C and TSST-1 of Staphylococcus aureus and Malassezia spp. in the serum of children with atopic dermatitis in the acute period of the disease. The determination of asIgE levels was performed in 84 children aged from 5 months to 17 years using the immunochemiluminescent method on the UniCAP 100 analyzer (Phadia, Sweden). The level of asIgE was evaluated on a scale of 6 classes.The sensitization to S. aureus enterotoxins was detected in 29 children with аsIgE concentration from 0.35 to 25.8 kU/L (I–IV classes). In 16 children were observed 8 polysensitization options to S. aureus allergens. Combinations of asIgE to A + B and A + B + C enterotoxins were most common – in every fourth and fifth child,respectively. Sensitization to Malassezia spp. was observed in 41 children with concentration from 0.38 to 98.9 KU/L (I–V classes). Polysensitization to both S. aureus and Malassezia spp. allergens was observed in one of two children. A higher degree of sensitisation to Malassezia spp allergens has been established compared to S. aureus.Conclusion. To improve the specific diagnostics of atopic dermatitis, it is advisable to examine the serum for a complete panel of recombinant S. aureus enterotoxins in combination with the determination of asIgE to Malassezia spp.

ABSTRACT Objective: To determine the presence of staphylococcal superantigen-specific IgE antibodies and degree of IgE-mediated sensitization, as well as whether or not those are associated with the severity of asthma in adult patients. Methods: This was a cross-sectional study involving outpatients with asthma under treatment at a tertiary care university hospital in the city of Rio de Janeiro, Brazil. Consecutive patients were divided into two groups according to the severity of asthma based on the Global Initiative for Asthma criteria: mild asthma (MA), comprising patients with mild intermittent or persistent asthma; and moderate or severe asthma (MSA). We determined the serum levels of staphylococcal toxin-specific IgE antibodies, comparing the results and performing a statistical analysis. Results: The study included 142 patients: 72 in the MA group (median age = 46 years; 59 females) and 70 in the MSA group (median age = 56 years; 60 females). In the sample as a whole, 62 patients (43.7%) presented positive results for staphylococcal toxin-specific IgE antibodies: staphylococcal enterotoxin A (SEA), in 29 (20.4%); SEB, in 35 (24.6%); SEC, in 33 (23.2%); and toxic shock syndrome toxin (TSST), in 45 (31.7%). The mean serum levels of IgE antibodies to SEA, SEB, SEC, and TSST were 0.96 U/L, 1.09 U/L, 1.21 U/L, and 1.18 U/L, respectively. There were no statistically significant differences between the two groups in terms of the qualitative or quantitative results. Conclusions: Serum IgE antibodies to SEA, SEB, SEC, and TSST were detected in 43.7% of the patients in our sample. However, neither the qualitative nor quantitative results showed a statistically significant association with the clinical severity of asthma.
