Clinical features and immunological markers of atopic dermatitis in elderly patients.

Abstract:

BACKGROUND:Atopic dermatitis (AD) is increasing among the elderly. Staphylococcus aureus colonization is one of the most important aggravating factors in AD. OBJECTIVE:This study analyses the clinical features of AD in elderly patients and determines the pathogenic roles of staphylococcal superantigens in AD with low and high total IgE levels. METHODS:S. aureus enterotoxin genes were evaluated using PCR. Additionally, S. aureus-specific IgE levels and peripheral blood lymphocyte profiles were assessed. RESULTS:A total of 44 women and 77 men diagnosed with AD with a mean age of 68.92 ± 6.51 years were evaluated. In 17 (68%) patients with AD and low levels of total IgE, there was a positive correlation between the positive results for enterotoxin B, S. aureus-specific IgE antibodies and Th1 cytokine profiles (Spearman's rank correlation test, r = 0.89, p < 0.05). CONCLUSION:Our results indicate that AD patients with low total IgE levels differ in immunopathogenesis from AD patients with high circulating levels of total IgE AD.
