Association between IL-10 (at position -592) and IL-4 (at position -589) genotype polymorphism with atopic and non-atopic asthma in children.

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.

Project description:PurposeInterleukin-10 (IL-10) potentially can promote the development of alloimmunity. The aim of this study was to investigate if the IL-10-592 CC genotype in the donor reduces the risk of relapse after hematopoietic stem cell transplantation (HSCT) and if that has an impact on event-free survival (EFS) and overall survival (OS).MethodsA cohort of 211 children with acute lymphoblastic leukemia (n = 99), acute myeloid leukemia (n = 69), myelodysplastic syndrome (n = 31) or chronic myeloid leukemia (n = 12) who underwent hematopoietic stem cell transplantation (HSCT) in a single center and their respective donors were genotyped of IL-10 gene for rs1800872 using TaqMan real-time polymerase chain reaction.ResultsThe IL-10-592 CC genotype was detected in 107 of the 211 donors (50.7%) and in 106 of the 211 patients (50.2%). Genotype AC was found in 95 donors (45.0%) and in 90 patients (42.7%). Nine donors (4.3%) and 15 patients (7.1%) were homozygous for AA. Ultimately, we observed a significantly reduced incidence of relapse rate (RR) in patients who were transplanted from a donor with the IL-10-592 CC genotype (19% versus 43% (AC) versus 49% (AA); P = 0.0007). In addition, a significant increase of EFS (P = 0.004) and OS (P = 0.006) was detected if the IL-10-592 CC genotype is present in the donor. The occurrence of the IL-10-592 CC genotype, in either donors or recipients, had no significant impact on acute and chronic graft-versus-host disease. In addition, the IL-10-592 genotype of the recipients was not relevant for the RR (P = 0.47434), the EFS (P = 0.840), and the OS (P = 0.535).ConclusionThe IL-10-592 CC genotype in the donor was associated with a significant decrease of RR which led to a significant increase of EFS and OS after HSCT. This is the first study to describe an association of the IL-10 gene polymorphism with RR, EFS, and OS after HSCT. Selecting a donor with the IL-10-592 CC genotype could be a useful therapeutic strategy for improving the outcome after allogeneic HSCT.
