Haplotype of IL-8 -251T and 781C is associated with the Susceptibility to Respiratory Syncytial Virus

A Lu, L Wang and X. Zhang    


Objective: To study the association of haplotypes of IL-8 -251T/A and 781 C/T single nucleotide polymorphisms (SNPs) with the susceptibility of respiratory syncytial virus (RSV).

Methods: This study included 101 hospitalized patients under 2 years who suffered from RSV pneumonia and108 hospitalized patients under 2 years who suffered only from pneumonia without RSV infection. Genotypes of two SNP loci in all enrolled persons were defined by allele-specific polymerase chain reaction. The allele’s frequencies of SNPs were analyzed with case–control study, linkage of two loci and haplotypes composed by the two loci were also studied.

Results: (i) The frequency of IL-8 -251T in cases was dramatically high (OR = 2.08, p = 0.0002). (ii) Haplotype of TC was significantly high in cases (p = 0.01).

Conclusion: These findings support that haplotype of TC composed by IL-8 -251T and 781C is associated with the susceptibility of RSV.
