Introduction: Asthma is the most prevalent chronic disease in childhood. Between 10% to 48% of patients with asthma in childhood have spontaneous remission of the disease during adolescence. However, the immunological mechanisms of this phenomenon being not completely known. General objective: To determine if there are differences in the serum levels of Interleukin 10 (IL-10) and Interferon Gamma (IFN-γ) in adolescents diagnosed with asthma in clinical remission without treatment (RA), compared with adolescents diagnosed with persistent asthma. (AP) and nonasthmatic and non-atopic adolescents (NA). Materials and methods: In the AP, AR and NA groups, 18, 15 and 15 participants were enrolled respectively, all between 12 and 17 years of age. Participants with a history of asthma completed the "Asthma Control Test" (ACT) questionnaire for people over 12 years of age. All the participants were interviewed, examined and a sample of peripheral blood was extracted, in a standardized manner, to quantify the eosinophil levels in an automated way; and the serum levels of IL-10 and IFN-γ by ELISA technique. A sub-analysis was also carried out in which patients from the AR and AP groups with a history of allergic asthma and patients from the NA group were included. Results: There was no statistically significant difference in the levels of IFN-γ (p=0.7133), IL-10 (p=0.2553) or the IL- 10/IFN-γ ratio (p=0.0687) between the patients in the AP, RA and NA. Regarding peripheral blood eosinophils, a statistically significant difference was found between the AP and NA groups (p=0.0464), especially in those with a history of allergic asthma (p=0.0075), being higher in the AP group; there was no statistically significant difference between the AR and NA groups, nor between the AR and AP groups. Conclusions: With respect to eosinophil levels in peripheral blood, there is a difference between AP and NA patients, being these higher in the AP group, especially in those with allergic asthma, their values being influenced by the serum levels of IFN- γ and IL-10 together, so it is postulated that the persistence of asthmatic disease during adolescence could be due in part to the production of proinflammatory Th1-type cytokines produced by eosinophils, since it has been reported that eosinophils are capable of secreting IFN-γ in response to both Th1 and Th2 stimuli and the production of this interleukin is not decreased by stimulation with IL-10, which in turn induces increased production of IL-12 by eosinophils. There is no difference in peripheral blood eosinophil levels between NA and RA patients or between RA and AP patients. There was no difference in the serum levels of IFN-γ, IL-10 or in the IFN-γ/IL-10 ratio among patients diagnosed with RA, PA, and NA.
