Correlation Between IL-13rs20541(A> G) Gene Polymorphism and Bronchial Asthma Among Iraqi Patients.

ABSTRACT:

Background

Bronchial asthma has a complicated genetic history. Changes in gene expression may be caused by gene polymorphism, cytokines play a central role. IL-13 is an interleukin that has been shown to play a role in the disease's immunopathogenesis. The current study investigated the relationship between rs20541 of the IL-13 gene and Bronchial asthma in Iraqi patients.

Methods

Seventy-five patient and fifty healthy individuals as a control. The DNA was extracted from blood samples. Detection of genotype IL-13SNP (rs20541) were achieved by RFLP-PCR.

Results

indicated a highly significant the levels of the IgE, and IL-13 in the patients compared to control at (p value≤ 0.01), (456.45±290.106 vs. 30.08±24.414), (59.5980±20.93750 vs.6.7034±4.10547) pg/ml respectively. Result shows no significant differences in the frequency distributions of IL-13 SNP (rs20541) for all genotypes in cases and controls. A protective role of asthma, (OR: 0.62; CI.95%: 0.23 - 1.6) and (OR 0.89; CI.95%:0.42 - 1.89) were observed for wild type homozygous and heterozygous genotype respectively. Whereas the AA genotype (42.7%) in cases and (34.0%) in control, that (OR:1.44; CI.95%:( 0.66 - 3.07) mutant homozygous were risk factors of asthma among individuals. The genotypes of IL-13 rs20541 (GG, AG, AA) among patients and controls were significantly correlated with IgE and IL-13 results at (p≤ 0.05).

Conclusion

AA genotype in case and control mutant homozygous were risk factors of asthma among individuals. It's possible that this has a predisposing impact on the development of asthma.

Project description:BackgroundSingle nucleotide polymorphisms (SNPs) in the interleukin 13 (IL13) gene are associated with vulnerability to allergic diseases, such as asthma and allergic conjunctivitis (AC). Periostin, as an IL13-induced protein, has emerged as a novel biomarker in several allergic diseases. Data among Egyptian patients are still scarce.AimTo find out the association of IL13 rs20541 gene polymorphism and serum levels of periostin with asthma and AC among Egyptian patients.Patients and methodsEighty-one Egyptian allergic patients with asthma, AC, and both asthma and AC (27 each), were enrolled in this case-control study. Twenty-seven age and gender-matched healthy volunteers served as controls. All participants were tested for IL13 rs20541 SNP by real-time polymerase chain reaction, TaqMan method. Serum levels of periostin and IL13 were assessed by ELISA.ResultsCompared to healthy subjects, asthmatic patients had a higher frequency of the homozygous adenine/adenine (AA) genotype at IL13 rs20541 SNP (14.8% vs 3.7%) and a lower frequency of the guanosine/guanosine (GG) genotype (51.9% vs 55.6%), while AC patients had higher GG genotype (70.4% vs 55.6%) with no AA genotype detected, yet no significant difference was noticed (p = 7.053). A significantly higher serum periostin in asthmatic patients compared to controls was found (p = 0.005). Higher levels of serum periostin, although nonsignificant, were recorded in AC patients compared to controls (22.88 ± 10.01ng/mL and 17.51 ± 3.17ng/mL, respectively). Periostin was significantly higher in patients with IL13 AA and GA genotypes compared to those with GG genotype (p = 0.016). A significant positive correlation between serum periostin and serum IL13 among allergic patients was recorded (r = 0.352, p < 0.001).ConclusionAmong Egyptian patients, serum level of periostin is significantly associated with asthma and positively correlates with IL13 level supporting its utility as a diagnostic biomarker. IL13 rs20541 gene polymorphism does not seem to play an obvious role in asthma and AC, which requires further evaluation.
