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.
The aim of this study was to determine the possible association of the three polymorphisms (A-1082G, T-819C, A-592C) in the IL-10 gene promoter with the susceptibility to hepatitis B virus (HBV)-related ALF in a Chinese population.
A recent genome-wide association study discovered that two polymorphisms, interferon (IFN) alpha receptor 2 (IFNAR-2) F8S and interleukin 10 receptor (IL10RB) K47E, were associated with susceptibility to hepatitis B virus (HBV) infection in Africa.
These results suggest that IL10 and IL20 gene variants influence HBV infection outcome and encourage the pursuit of further studies of these cytokines in HBV pathogenesis.
PD-1 expression was assessed by (1) flow cytometry and (2) quantitative real-time polymerase chain reaction; hepatitis B virus (HBV)-specific CD8+ T-cells were quantitated by pentamer staining; T-cell reactivity to HBV antigens was determined by interferon gamma (IFNgamma) and interleukin 10 (IL-10) enzyme-linked immunosorbent spot (ELISPOT) assays; and central/effector memory phenotypes were defined by phenotypic markers.
There was no difference in the HBV DNA levels during hepatitis flares between patients with genotypes B and C. Patients with genotype B had a significantly higher number of IFN-gamma producing cells [with hepatitis B core antigen (HBcAg) stimulation] and lower number of IL-10 producing cells (with HBcAg and HBeAg stimulation) compared with patients with genotype C (P = 0.011, =0.043, <0.001 respectively).
The IL-10 gene promoter -592 C/C genotype was related to clearance of HBV infection in logistic regression analysis after adjusting for age and sex (P = 0.003).
Chronicity in hepatitis B virus (HBV) infection is maintained by increased type 2 T-helper cell response, possibly because of increased interleukin-10 (IL-10) productions.
To explore the relationship between cytokines (tumor necrosis factor-alpha, interferon-gamma, 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.
Increased IL10 production mediated by IL10-ht2 suggests that up-regulated IL10 accelerates progression of chronic HBV infection, especially to HCC development.
We investigated the serum levels of interleukin (IL)-6, IL-10, IL-12, and interferon (IFN)-gamma in HBV-infected Vietnamese patients to determine whether they were related to the outcome of HBV infection.
To analyze the potential role of these cytokines in human fulminant hepatitis B, we used immunohistochemistry to study expression of IL-12, IFN-gamma, and IL-10 in explant livers of 11 patients with fulminant hepatitis B, 5 patients with fulminant hepatitis due to other etiologies, 37 patients with chronic liver disease (CLD; hepatitis B virus, n = 15; hepatitis C virus, n = 10; primary biliary cirrhosis, n = 12), and 10 normal controls (NCs).
The IL-10 genotype (polymorphic bases at positions -1082 and -819) was determined in 272 chronic hemodialysis patients using highly specific PCR and related to the patients' response to a triple vaccination against hepatitis B. Secretion of IL-10 and IL-6 by peripheral blood leucocytes in vitro was determined by ELISA.

Immunocompromized patients who are unresponsive to hepatitis B vaccination seem to be unable to enhance IL-10 synthesis for control of monokine overproduction.
