Abstract:
Objective To explore the relationship between interleukin (IL)-10 gene polymorphisms and the susceptibility or the outcomes of HCV infection among high-risk populations in Jiangsu province.Methods IL-10 gene SNPs were detected in 1555 subjects including 264 self-limited HCV infections.371 persistent HCV infections and 920 healthy controls were selected through Taqman-MGB.Results After adjusted for cofounders as sex,age and high-risk population,data from logistic regression analysis showed that the distribution of IL-10 genotypes among the controls,spontaneous clearances and those with persistent infections did not show much differences.Results from further stratified analysis showed that,at the position of-819T/C,when compared with TT genotype,TC genotype had a significantly increasing chance of self-limited HCV infection among middle-aged,females and paid blood doners (adjusted OR values and 95％ CI were:2.160,1.163 4.011 ；1.693,1.066-2.688 and 4.084,1.743-9.570).It also had a lower risk of progressing to persistent HCV infection among those paid blood doners (the adjusted OR values and 95％CI were:0.312,0.130-0.747 ).CC genotype had a higher chance of self-limited HCV infection among people underwent blood dialysis (the adjusted OR values and 95％CI were:2.120,1.071 -4.197).Results also showed a decreased risk of progressing to persistent infection among paid blood doners (the adjusted OR values and 95％CI were:0.156,0.043-0.566).At the position of -592A/C,when compared to AA genotypc,the AC genotype had a significantly increasing chance of self-limited HCV infection among middle-aged,femalcs and paid blood doners (the adjusted OR values and 95％ CI were:2.176,1.173-4.037；1.659,1.055-2.607;3.704,1.625-8.443) but had an increased risk of persistent HCV infection among females (the adjusted OR values and 95％CI were:1.525,1.017-2.286).AC genotype showed an increased opportunity to progress to HCV persistent infection among drug users (the adjusted OR values and 95％CI were:1.845,1.122-3.034) but had a reduced risk of progressing to HCV persistent infection among paid blood doners (the adjusted OR values and 95％CI were:0.361,0.155-0.841 ).CC genotype had an increased opportunity to self-linited HCV infection as well as having a dccreased risk of progressing to persistent infection among paid blood donets (the adjusted OR values and 95％CI were:3.125,1.016-9.605；0.218,0.063-0.748).At the position of-1082A/G,AG/GG genotypcs had an increased chance of self-limited infection among blood doners (the adjusted OR values and 95％CI were:3.780,1.620-8.820).Conclusion IL-10-819T/C,-592A/C,-1082A/G SNPs might be related with the susceptibility and the outcomes of HCV infection among populations at high risk.
