The Relationship Between Serum Level of Interleukin-10 and State of the Disease with Atopic Dermatitis and Helminth in Children

Abstract

Background: IL-10 is an antiinflammatory cytokine. During infection it inhibits the activity of Th1 cells, NK cells, and macrophages. Regulatory cytokine interleukin-10 (IL-10) has been proposed as a key molecule involved in the attenuation of helminth infection and chronic inflammation, such as atopic dermatitis. The maintenance of the asymptomatic state is now recognized as reflecting an immunoregulatory environment, which may be promoted by parasites, and involves multiple levels of host regulatory cells and cytokines; currently, there is much interest in whether helminth-associated immune regulation may ameliorate allergy and autoimmunity. The objective of this study was to measure the IL-10 level in healthy person, atopic dermatitis, helminth infection and healthy persons. Methods: Levels of IL-10 was measured by ELISA technique. Kato-Katz method is used to determine the number of eggs of helminth. Results: Our study showed that those aged > 5 years old and helminth infection without atopic dermatitis had higher levels of IL-10 (3.05 ± 2.44) which was significantly higher (p < 0.001) than in children whose atopic dermatitis without the helminth infection (1.76 ± 2.72). We found that increased levels of IL-10 in helminth infection (3.05 ± 2.44) higher than healthy subjects (1.72 ± 1.74); but not statistically significant (p = 0.072). The level of IL-10 did not have significant relationship either at age ≤ 5 years old and > 5 years old in others group. Also, no correlation between egg count of helminth and level of IL-10 in serum. Conclusion: The serum of IL-10 was significantly higher in children > 5 years with helminth infection without atopic dermatitis than children with atopic dermatitis.
