Abstract
Purpose
Even though Malassezia yeast may play an important role in the exacerbation of atopic dermatitis (AD), only a few studies of Malassezia infection have been conducted in children with AD. Thus, we compared each of clinical findings, including the severity of head and neck dermatitis and laboratory results depending on specific IgE against Malassezia furfur.
Methods
This cross-sectional study was carried out on 121 children aged 3 months to 18 years between April and July of 2014. Retrospective data was collected using the medical records, and patients were divided into 2 groups according to the presence of Malassezia sensitization.
Results
Specific IgE against Malassezia (group 1) was observed in 28 of all patients (23.1%). Group 1 children were at an older age (9.1±6.9 vs. 2.1±3.7, P<0.001). Group 1 children had a higher SCORing Atopic Dermatitis (SCORAD) index (46.4±21.0 ng/mL vs. 37.2±13.4 ng/mL, P=0.001), and total IgE (1,324.2±1,166.0 IU/mL vs. 209.5±532.5 IU/mL, P<0.001) compared to group 2 children (Malassezia-). In the group 1, the correlation between the Malassezia-specific IgE and 25-hydroxyvitamin D3 was negatively weak (r=–0.106) and not statistically significant (P=0.246). Furthermore, Malassezia-specific IgE and the SCORAD index (r=0.281, P=0.002) or total IgE (r=0.380, P<0.001) were positively correlated.
