Allele polymorphisms of interleukin-10 and hepatitis B, C virus infection

Background Interleukin 10 (IL-10) is an important cytokine with anti-inflammatory, anti-immune and anti-fibrotic functions. This study aimed at evaluating the relationship between allele polymorphisms in the IL-10 promoter region and hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.
Methods The odds ratios (ORs) of IL-10 allele distributions in patients with HBV or HCV infection were analyzed against healthy controls. All the relevant studies in PubMed were identified, and poor qualified studies were excluded. The meta-analysis software REVMAN 4.2 was applied for investigating heterogeneity among individual studies and summarizing all the studies. The publication bias was also evaluated.
Results This study demonstrated a significant association between the IL-10-592 A/C polymorphism and HBV infection in the Asian population under the overall effect size of allele A versus C. In our subgroup meta-analysis, we found a significant association of IL-10-592 A/C polymorphism to HCV infection susceptibility in Asian populations, although sensitivity analysis showed that the combined result was not associated with the worldwide population. Other IL-10 allele polymorphisms were not associated with HBV or HCV infection.
Conclusion IL-10-592 A/C allele might be a risk factor for HBV or HCV in Asians but not in Europeans.

     

Relationship between cytokines gene polymorphism and susceptibility to hepatitis B virus intrauterine infection

Background The influences of genomic background are confirmed in more diseases. Immunologic tolerance after intrauterine infection of hepatitis B virus is considered to occur in T cells. Cytokines work effectively in eliminating virus by immune system after hepatitis B virus infection. To explore the relationship between cytokines （tumor necrosis factor-α, interferon-γ, interleukin-4 and interleukin-10）, which expressed abnormal quantity in the peripheral blood to intrauterine hepatitis B virus infectious children, gene single nucleotide polymorphism （SNP） and susceptibility to hepatitis B virus intrauterine infection. Methods This is a cross sectional study of molecular clinical epidemiology. The subjects in this study were selected from outpatients of hepatitis B vaccine follow-up special clinics of our hospital in the period. According to intrant criteria, the high risk children of hepatitis B virus （HBV） intrauterine infection were divided into immune failure group （group Ⅰ） ; and immune effective group （group Ⅱ） and non high risk children belonged to the control group. Four gene SNP sites of TNF-α -238, IFN-γ ＋874, IL-4 -590 and IL-10 -1082 were determined by real-time quantitative fluorescent polymerase chain reaction （PCR）. Results The significant differences of TNF-α- 238 A allele frequency were found between group Ⅰand group Ⅱ（X^2 =6. 797, P 〈 0.05 ） and between group Ⅰ and the control group （ X^2 = 9. 513, P 〈 0.05 ）. No evident differences of TNF-α- 238 A were found between group Ⅱand control group （ X^2 = 0. 047, P 〉 0. 05 ） ; the significant differences of IFN-γ ＋ 874 A allele frequency were found between group Ⅰand group Ⅱ（ X^2 = 7. 238, P〈0. 05）, and between group Ⅰand the control group （X^2 =5. 199,P 〈0. 05）. No evident differences were found between groupⅡ and the control group （ X^2 =0. 602 ,P 〉0. 05 ） ; the significant differences of IL-4 -590 C/T allele frequency were not found between groupⅠand group Ⅱ （ X^2 = 0. 632, P 〉 0. 05 ） , also group Ⅰ and the control group （ x^2 = 0. 584, P 〉 0. 05 ）, and the group Ⅱ and the control group （ X^2 = 0. 004, P 〉 0. 05 ） respectively; The significant differences of IL-10 - 1082 G allele frequency were found between group Ⅱand group Ⅰ（x^2 = 10. 359,P 〈0. 001 ）, and between group Ⅱ and the controls （x^2 =35. 418,P 〈0. 001 ）, but the significant differences were not found between group Ⅰ and the control group （ X^2 = 1. 759,P 〉 0. 05 ）. Conclusions This study suggested the possibility that the TNF-α-238 A allele and IFN-γ＋ 874 A allele were associated with HBV intrauterine infection. There was no evident relationship between IL-4 -590 C/T allele SNP and susceptibility to HBV intrauterine infection, but the IL-10 - 1082 G allele was associated with preventive efficacy to HBV intrauterine infection.

Association between CISH polymorphisms and spontaneous clearance of hepatitis B virus in hepatitis B extracellular antigen-positive patients during immune active phase

Background Some hepatitis B extracellular antigen （HBeAg）-positive chronic hepatitis B （CHB） patients in their immune active phase can clear the virus spontaneously and enter into an inactive hepatitis B virus （HBV） carrier state,indicating a benign prognosis.In this study,the association between cytokine-inducibie SRC homology 2 domain protein （C/SH） gene polymorphisms at-292 （rs414171） and the spontaneous clearance of HBV in HBeAg-positive CHB patients in immune the active phase was investigated.Methods Seventy HBeAg-positive CHB patients in the immune active phase were followed up for 76 weeks without antiviral therapy.The alanine transaminase,aspartate transaminase,HBV DNA,HBeAg and hepatitis B extracellular antibody levels were tested regularly.At week 76,27 patients were classified into group A （HBV DNA level below 2 104 IU/ml and the value of HBeAg declined below 10％ of the baseline at week 76）,and 43 patients were classified into group B （HBV DNA level higher than 2×104 IU/ml or the value of HBeAg did not decline substantially at week 76）.CISH （rs414171） polymorphisms were also tested using the iPLEX system.Results The HBV DNA levels at week 12 were significantly greater in group B compared with group A （group A：（6.87±1.40） log10IU/ml; group B：（7.61±1.38） log10IU/ml,P=0.034） and the HBeAg values were greater in group B at week 28 compared with group A （P=0.001）.The differences in HBV DNA and HBeAg values increased between the groups over time.Sixteen patients in group A and 11 in group B were genotype AA.Those with genotype AT or TT included 11 in group A and 31 in group B （AA vs.AT and TT,odds ratio 4.10 （95％ confidence interval：1.462-11.491）,P=0.006）.Conclusion CISH gene polymorphisms at-292 （rs414171） are associated with HBV clearance in HBeAg-positive CHB patients in the immune active phase,and AA is a favorable genotype for this effect.

RANTES gene single nucleotide polymorphisms and expression in patients with chronic hepatitis B virus infection

Background Regulated on activation, normal T-cell expressed and secreted (RANTES) plays a critical role in T-lymphocyte activation and proliferation. The process is involved in both acute and chronic phases of inflammation. The present study was to ascertain the possible correlations between chronic hepatitis B virus (HBV) infection and the RANTES gene polymorphisms and their expression. Methods The study included 130 HBV negative healthy donors and 152 patients with chronic hepatitis B (CHB) virus infection. The polymerase chain reaction (PCR) and restriction fragment length polymorphisms (RFLPs) were used to detect RANTES gene single nucleotide polymorphisms (SNPs). RANTES levels in the platelet depleted plasma were detected by enzyme linked immunosorbent assay (ELISA). Results RANTES alleles -403G, -28C and In1.1T were the predominant alleles in the subjects studied. No significant correlation was found between CHB infection and the RANTES alleles, while a significant correlation was found between CHB infection and increased RANTES expression in platelet depleted plasma (P&lt;0.05). Conclusions SNPs in RANTES gene do not affect chronic HBV infection or the outcome of interferon-α treatment in patients positive for HBV “e” antigen (HBeAg+). However, patients with CHB infection express the higher levels of plasma RANTES, which is thus associated with CHB infection.
