Abstract
OBJECTIVES
Asthma is the most prevalent respiratory disease, caused by chronic bronchial inflammation. Cytokines are known to play an important role in the pathophysiology of asthma. This study aimed to compare interleukin-4 (IL-4) and interleukin-10 (IL-10) gene polymorphisms between Iranian pediatric asthmatic patients and healthy controls and to investigate IL4 and IL10 gene variations in children with atopic and non-atopic asthma phenotypes.
METHODS
In this prospective case-control study, a total of 95 unrelated pediatric asthmatic patients were recruited according to the Global Initiative for Asthma (GINA) criteria. The control group comprised two subgroups of 538 and 491 healthy individuals, undergoing IL4 and IL10 polymorphism assessments, respectively. The IL4 -589C/T (rs2243250) and IL10 -592A/C (rs1800872) gene polymorphisms were evaluated using the tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) assay.
RESULTS
The findings indicated a significant difference in IL4 gene polymorphisms at position -589 between the asthmatic and healthy control groups. However, no significant difference was found in terms of IL10 gene polymorphisms, and they were not associated with atopy in the patients.
CONCLUSION
The IL4 -589C/T polymorphism (rs2243250) can be a risk factor for asthma susceptibility, whereas the IL10 -592A/C polymorphism (rs1800872) is not a risk factor in the Iranian pediatric population. The results also showed that these polymorphisms are not risk factors for atopy in asthmatic children.
