Abstract
Hepatitis B virus (HBV) infection is a global public health issue. Interferon-α (IFN-α) treatment has been used to treat hepatitis B for over 20 years, but fewer than 5% of Asians receiving IFN-α treatment achieve functional cure. Thus, IFN-α retreatment has been introduced to enhance antiviral function. In recent years, immune-related studies have found that the complex interactions between immune cells and cytokines could modulate immune response networks, in-cluding both innate and adaptive immunity, triggering immune responses that control HBV replication. However, heterogeneity of the immune system to control HBV infection, particularly HBV-specific CD8+ T cell heterogeneity, has consequ-ential effects on T cell-based immunotherapy for treating HBV infection. Altogether, the host’s genetic variants, negative-feedback regulators and HBV components affecting the immune system's ability to control HBV. In this study, we reviewed the literature on potential immune mechanisms affecting the immune control of HBV and the clinical effects of IFN-α treatment and retreatment.

Abstract
Hepatitis B virus (HBV) subgenotype F1b infection has been associated with the early occurrence of hepatocellular carcinoma in chronically infected patients from Alaska and Peru. In Argentina, however, despite the high prevalence of subgenotype F1b infection, this relationship has not been described. To unravel the observed differences in the progression of the infection, an in-depth molecular and biological characterization of the subgenotype F1b was performed. Phylogenetic analysis of subgenotype F1b full-length genomes revealed the existence of two highly supported clusters. One of the clusters, designated as gtF1b Basal included sequences mostly from Alaska, Peru and Chile, while the other, called gtF1b Cosmopolitan, contained samples mainly from Argentina and Chile. The clusters were characterized by a differential signature pattern of eight nucleotides distributed throughout the genome. In vitro characterization of representative clones from each cluster revealed major differences in viral RNA levels, virion secretion, antigen expression levels, as well as in the localization of the antigens. Interestingly, a differential regulation in the expression of genes associated with tumorigenesis was also identified. In conclusion, this study provides new insights into the molecular and biological characteristics of the subgenotype F1b clusters and contributes to unravel the different clinical outcomes of subgenotype F1b chronic infections.

Abstract
BACKGROUND Studies have reported that the immune system modulation genes are involved in the seroconversion during hepatitis B virus (HBV) infection. Here, a systematic review with meta-analysis is implemented on the association of polymorphisms in immune-related genes with the spontaneous hepatitis B surface antigen (HBsAg) seroconversion. METHODS A systematic literature search was conducted in the main electronic databases of Scopus, PubMed, and Web of Science before May 2022. Pooled odds ratio (OR) and their corresponding 95% confidence interval (CI) were used to evaluate the strength of the association between genetic polymorphisms and the chance of spontaneous HBsAg seroconversion. RESULTS A total of 40 studies finally included for meta-analysis of 2 HLA-DP SNPs, 2 HLA-DQ SNPs, 3 IFNL3/4 SNPs, 2 IL10 SNPs, and 5 TNF SNPs. Based on the overall pooled analysis, HLA-DP rs3077 A (OR = 1.47, 95%CI: 1.32-1.65), HLA-DP rs9277535 A (OR = 1.48, 95%CI: 1.32-1.66), HLA-DQ rs2856718 G (OR = 1.37, 95%CI: 1.18-1.59), HLA-DQ rs7453920 A (OR = 1.41, 95%CI: 1.04-1.93), IFNL3/4 rs12980275 G (OR = 1.26, 95%CI: 1.01-1.58), TNFA rs1799964 T (OR = 1.17, 95%CI: 1.02-1.35), and TNFA rs1800630 C (OR = 1.26, 95%CI: 1.03-1.55) increased significantly the chance of spontaneous HBsAg seroconversion. CONCLUSION This meta-analysis showed that the HLA-DP gene rs3077 and rs9277535 SNPs, HLA-DQ gene rs2856718 and rs7453920 SNPs, IFNL3/4 gene rs12980275 SNP, TNFA gene rs1799964 and rs1800630 SNPs are involved in the spontaneous HBsAg seroconversion.

The altered HLA-DQ expression in peripheral blood T cells of chronic hepatitis B patients characterizes the function of T cells. J Viral Hepat 2022; 29:340-351.

Abstract
OBJECTIVE This study aimed to clarify the expression of HLA-DQ and granulysin in peripheral blood T-cell subsets in patients with chronic hepatitis B virus (CHB) and to evaluate their significance in assisting CHB diagnosis and immune status assessment. METHODS Peripheral blood from 34 CHB patients, 36 inactive HBsAg carriers and 33 healthy controls were collected, and HLA-DQ and granulysin in a series of T-cell subsets were analysed by flow cytometry. The ability to secrete IL-10 and IFN-γ and the functional T-cell subsets were measured in Treg and CD4 cells expressing HLA-DQ or not. Correlation analyses were further conducted between HLA-DQ/granulysin-related subsets and clinical indicators of HBV infection, and ROC curves were built to evaluate diagnosis efficiency of HLA-DQ-related subsets. RESULTS HLA-DQ+ percentages in circulating CD4 T cells were downregulated in CHB patients. The proportions of HLA-DQ + Tfh in CHB were upregulated while HLA-DQ+ percentages in Treg were decreased. In terms of function, the IFN-γ secretion ability of CD4 + T cells and IL-10 secretion in Tregs were stronger in HLA-DQ+ than HLA-DQ- subsets. HLA-DQ + CD4 + T cells and HLA-DQ + Treg were negatively correlated with HBV-DNA, while HLA-DQ + Tfh and Tfc cells were positively correlated with HBV-DNA and ALT. HLA-DQ + Treg/Tfh/Tfc could help to distinguish CHB from inactive HBsAg carriers. CONCLUSION HLA-DQ on T cells can characterize the function of T-cell subsets and analysis of HLA-DQ can help to evaluate immune status and assist in diagnosis of CHB.

Abstract
Chronic hepatitis B (CHB) infection results in multiple clinical phenotypes of varying severity. One of the critical gaps in CHB management is the lack of a genetic-based tool to aid existing hepatocellular carcinoma and cirrhosis risk stratification models for patients with active CHB. Such individual predictive models for CHB are plagued by an inherent limitation of discriminatory power that clearly indicates the need for their improvement. In this article, we highlight genetic association studies in CHB that identified HLA and cytokine genetic susceptibility loci to CHB. We advance the position that translating CHB genetic susceptibility loci into polygenic risk scores will be a welcome addendum to the current arsenal of CHB outcome predictive models. We conclude with comments on hurdles that future research efforts should address within the research enclave of CHB and advocate for increased genetic data representation from sub-Saharan Africa.

Abstract
Viral hepatitis, secondary to infection with hepatitis A, B, C, D, and E viruses, are a major public health problem and an important cause of morbidity and mortality. Despite the huge medical advances achieved in recent years, there are still points of conflict concerning the pathogenesis, immune response, development of new and more effective vaccines, therapies, and treatment. This review focuses on the most important research topics that deal with issues that are currently being solved, those that remain to be solved, and future research directions. For hepatitis A virus we will address epidemiology, molecular surveillance, new susceptible populations as well as environmental and food detections. In the case of hepatitis B virus, we will discuss host factors related to disease, diagnosis, therapy, and vaccine improvement. On hepatitis C virus, we will focus on pathogenesis, immune response, direct action antivirals treatment in the context of solid organ transplantation, issues related to hepatocellular carcinoma development, direct action antivirals resistance due to selection of resistance-associated variants, and vaccination. Regarding hepatitis D virus, we describe diagnostic methodology, pathogenesis, and therapy. Finally, for hepatitis E virus, we will address epidemiology (including new emerging species), diagnosis, clinical aspects, treatment, the development of a vaccine, and environmental surveillance.

Abstract
Background:
The development and progression of hepatitis B (HBV)-related disease
can lead to liver cirrhosis and hepatocellular carcinoma (LC and HCC, respectively). Human leukocyte
antigen (HLA) DQ polymorphism has been reported in other recent studies to deal with the association
between HBV and liver disease. Our study on the Egyptian population was introduced to
assess the strong association between HLA-DQ polymorphism and HBV infection in addition to
the progression of HCC.
Aim:
The aim of this work was to estimate HLA-DQ gene polymorphisms in HBV and HCC.
Methods:
HLA-DQ genotype polymorphism was assayed by using the ABI Taq Man allelic discrimination
assay in different groups in this study. According to the relevant HLA Class II single
nucleotide polymorphism (SNP) literature, one single nucleotide polymorphism (SNPs) was selected
as the candidate site; it was an HLA-DQ, which showed minor allele frequencies AA, GA, and
GG.
Results:
Haplotype analysis was performed on all the subjects in the study; AA haplotype was the
most frequent haplotype in HCC cases (18%) in comparison with HBV and healthy individuals
(3%). The haplotype GA was more frequent in the HCC group and slightly more frequent in LC
when compared to HBV only cases and also when compared to the control group. In contrast, the
GG haplotype was recorded less frequently in HCC individuals, but the HBV and LC groups
showed more frequency of this haplotype compared with the HCC group. There was a correlation
between AFP serum levels and the frequency of GA and AA polymorphism in HCC cases.
Conclusion:
We found that AA and GA haplotype was significantly most frequent in HCC. Our
findings suggest that HLA-DQ AA and GG polymorphism might serve as a novel potential predictive
marker for HCC and may function in tumorigenesis of HBV.

Abstract
Human leukocyte antigen (HLA), also known as human major histocompatibility complex (MHC), is encoded by the HLA gene complex, and is currently known to have the highest gene density and the most polymorphisms among human chromosomal areas. HLA is divided into class I antigens, class II antigens, and class III antigens according to distribution and function. Classical HLA class I antigens include HLA-A, HLA-B, and HLA-C; HLA class II antigens include HLA-DP, HLA-DQ, and HLA-DR; nonclassical HLA class I and II molecules include HLA-F, E, H, X, DN, DO, and DM; and others, such as complement, are class III antigens. HLA is closely related to the body's immune response, regulation, and surveillance and is of great significance in the study of autoimmune diseases, tumor immunity, organ transplantation, and reproductive immunity. HLA is an important research topic that bridges immunology and clinical diseases. With the development of research methods and technologies, there will be more discoveries and broader prospects.

Abstract
Hepatitis B virus (HBV) infection is still a serious health threat worldwide. The outcomes of HBV infection consist of spontaneous HBV clearance and chronic HBV infection. Multiple factors contribute to the disparity of HBV infection outcomes, including host factors, viral factors and environmental factors. The present review comprehends the current researches mainly focusing on the relationships between genetic determinants, including single nucleotide polymorphisms (SNPs) and haplotypes, and susceptibility of HBV infection, namely chronic (persistent) HBV infection and HBV clearance. A number of determinants in the chromosomes, including mutations in human leukocyte antigens (HLAs), cytokines genes, toll-like receptors (TLRs), and other genes are related to the human susceptibility to HBV infection. Among the above variants, some of those in HLAs have been studied and replicated in multiple-ethnic populations and came to consistent conclusions, while some others are novel and need to be evaluated further.

Abstract
AIM To assess the association of viral and host genetic variability with the outcome of acute infection with hepatitis B virus subgenotype F1b (HBV/F1b). METHODS The cohort consisted of 26 patients with acute HBV/F1b infection who exhibit different outcomes: spontaneous resolution (n = 10), progression to chronic hepatitis (n = 10) and acute liver failure (n = 6). HLA SNPs (rs3077, rs9277542, rs2856718 and rs7453920) were determined. The S gene and core promoter/precore/core region were direct sequenced, and this latter region was also ultra-deep sequenced. Mean number of mutations, mutation rate, Shannon entropy, positive selection sites and mutational patterns of quasispecies were compared between groups. RESULTS HLA SNPs were associated with spontaneous resolution or progression to chronic hepatitis, but not with the development of acute liver failure. The mean number of mutations in the S gene was similar among the three groups. Patients with spontaneous resolution had the lowest number of mutations, mutation rates and Shannon entropy values in the precore/core compared to the other two groups. Ten positive selection sites mapped on HLA-restricted epitopes were related to progression to chronic hepatitis and acute liver failure. Mutations T1753C, A1762T, G1764A, C1766T, T1768A G1896A, G2092T and T2107C were associated with acute liver failure and progression to chronic hepatitis. CONCLUSION Highly heterogeneous and complex HBV precore/core carrying specific point mutations, combined with the host HLA background, were associated with a worse clinical outcome of acute HBV/F1b infection.

Abstract
Chronic hepatitis B virus (HBV) infection is still a major health problem worldwide. Recently, a great number of genetic studies based on single nucleotide polymorphisms (SNPs) and genome-wide association studies have been performed to search for host determinants of the development of chronic HBV infection, clinical outcomes, therapeutic efficacy, and responses to hepatitis B vaccines, with a focus on human leukocyte antigens (HLA), cytokine genes, and toll-like receptors. In addition to SNPs, gene insertions/deletions and copy number variants are associated with infection. However, conflicting results have been obtained. In the present review, we summarize the current state of research on host genetic factors and chronic HBV infection, its clinical type, therapies, and hepatitis B vaccine responses and classify published results according to their reliability. The potential roles of host genetic determinants of chronic HBV infection identified in these studies and their clinical significance are discussed. In particular, HLAs were relevant for HBV infection and pathogenesis. Finally, we highlight the need for additional studies with large sample sizes, well-matched study designs, appropriate statistical methods, and validation in multiple populations to improve the treatment of HBV infection.

Liver Int 2019; 39:646-654. [PMID: 30471179 DOI: 10.1111/liv.14008] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 10/11/2018] [Accepted: 11/07/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND & AIMS Acute hepatitis B virus (HBV) infections may clear spontaneously or become chronic and run through different phases. The single nucleotide polymorphisms (SNPs) rs3077, rs9277535 and rs9277534 within the human leucocyte antigen (HLA)-DP gene have been found to be associated with HBV susceptibility and persistence in Asians. However, evidence for the influence of these variants in Caucasians has been limited so far. The aim of our study was to investigate the impact of these polymorphisms on the outcome of HBV infections in a large Caucasian population. METHODS In this case-control study, we retrospectively analysed 1111 Caucasian individuals, including 618 with chronic HBV infections (CHB), 239 with spontaneous HBsAg seroclearance (SC) and 254 healthy controls (HC). The rs3077, rs9277535 and rs9277534 SNPs were genotyped by a polymerase chain reaction from blood samples and melting curve analysis. RESULTS A significant difference in the allele distributions was observed only for the rs3077 SNP between the HC and the CHB group as well as between the SC and CHB groups. The rs3077-C allele was associated with a lower probability for spontaneous HBsAg seroclearance in comparison with the rs3077-T allele (OR 0.704, 95% CI 0.509-0.974; P = 0.033). No association of the three SNPs with the stages of chronic HBV infection was found. CONCLUSION This is the first study demonstrating an association of the rs3077-T allele with spontaneous HBsAg seroclearance in Caucasians. Further studies are needed to elucidate the role of HLA-DP variants in disease pathogenesis and their potential role for individualized disease management.

Abstract
The clinical outcome of Hepatitis B Virus (HBV) infection depends on the success or failure of the immune responses to HBV, and varies widely among individuals, ranging from asymptomatic self-limited infection, inactive carrier state, chronic hepatitis, cirrhosis, hepatocellular carcinoma, to liver failure. Genome-wide association studies (GWAS) identified key genetic factors influencing the pathogenesis of HBV-related traits. In this review, we discuss GWAS for persistence of HBV infection, antibody response to hepatitis B vaccine, and HBV-related advanced liver diseases. HBV persistence is associated with multiple genes with diverse roles in immune mechanisms. The strongest associations are found within the classical human leukocyte antigen (HLA) genes, highlighting the central role of antigen presentation in the immune response to HBV. Associated variants affect both epitope binding specificities and expression levels of HLA molecules. Several other susceptibility genes regulate the magnitude of adaptive immune responses, determining immunity vs tolerance. HBV persistence and nonresponse to vaccine share the same risk variants, implying overlapping genetic bases. On the other hand, the risk variants for HBV-related advanced liver diseases are largely different, suggesting different host-virus dynamics in acute vs chronic HBV infections. The findings of these GWAS are likely to pave the way for developing more effective preventive and therapeutic interventions by personalizing the management of HBV infection.

Multiple doses of hepatitis B recombinant vaccine for chronic hepatitis B patients with low surface antigen levels: a pilot study. Hepatol Int 2018; 12:456-464.

Abstract
BACKGROUND Seroclearance of hepatitis B surface antigen (HBsAg) has been rarely achieved in the treatment of chronic hepatitis B (CHB) patients. We administered HBsAg-based recombinant vaccine in patients with low HBsAg concentrations. METHODS Twenty hepatitis B e antigen-negative patients, with HBsAg < 1000 IU/ml, were enrolled. Vaccines were administered every 8 weeks for 48 weeks (seven doses). HBsAg levels and anti-HBs were assayed longitudinally until 48 weeks post-vaccination. HLA genotyping and cDNA microarray were performed to search for response predictors. RESULTS Nineteen patients completed the study. At the end of vaccination, HBsAg declined significantly (Δ = - 0.27 ± 0.49 log IU/ml, p = 0.0005). The annual decline rate was significantly greater than that of an age-, gender-, and baseline HBsAg-matched control group (Δ = - 0.18 ± 0.46 versus + 0.11 ± 0.42 log IU/ml/year; p = 0.0229). Two patients achieved HBsAg seroclearance. Fourteen had significant HBsAg decline (Δ = - 0.64 ± 0.88 log IU/ml). No significant adverse events occurred during the trial. cDNA microarray identified the top up- and down-regulated genes in responders as HLA-DQ and HLA-DMB, respectively. HLA genotyping identified HLA-DQB1*04, HLA-DRB1*04, and HLA-B*40 as predictors for non-response (p = 0.0499, 0.0152, and 0.0314, respectively). CONCLUSIONS In low-level HBsAg CHB patients, serial HBsAg-based vaccinations were safe, resulting in significant HBsAg decline. HLA gene expression and genotypes played a role in vaccine responsiveness (ClinicalTrials.gov Identifier: NCT01817725).

Quantitative assessment of HLA-DQ gene polymorphisms with the development of hepatitis B virus infection, clearance, liver cirrhosis, and hepatocellular carcinoma. Oncotarget 2017; 9:96-109. [PMID: 29416599 PMCID: PMC5787527 DOI: 10.18632/oncotarget.22941] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2017] [Accepted: 11/03/2017] [Indexed: 12/14/2022] Open
Abstract
Hepatitis B is one of the most common infectious diseases, which leads to public health problems in the world, especially in Asian counties. In recent years, extensive human genetic association studies have been carried out to identify susceptible genes and genetic polymorphisms to understand the genetic contributions to the disease progression of HBV infection. HLA-DQ gene variations have been reported to be associated with HBV infection/clearance, disease progression and the development of hepatitis B-related complications, including liver cirrhosis (LC) and hepatocellular carcinoma (HCC). However, the results are either inconclusive or controversial. Therefore, to derive a more precise estimation of the association, a meta-analysis was performed. Our data revealed that the HLA-DQ alleles rs2856718-G, rs7453920-A and rs9275319-G were significantly associated with decreased risk of HBV infection and HBV natural clearance. Logistic regression analyses showed that HLA-DQ alleles rs9275572-A significantly increased HBV infection clearance, and decreased HBV natural clearance. However, rs2856718-G and rs9275572-A were not associated with development of cirrhosis. The HLA-DQ polymorphisms (rs2856718 and rs9275572) were associated with a decreased HBV-related HCC risk in all genetic models, but rs9272105-A increased the risk of HBV-related HCC. In addition, no significant association was observed between HLA-DQ rs9275319-G polymorphism and HBV-related HCC. These stratified analyses were limited due to relatively modest size of correlational studies. In future, further investigation on a large population and different ethnicities are warranted. Our findings contribute to the personalized care and prognosis in hepatitis B.

Relationship between HLA-DQ Gene Polymorphism and Hepatitis B Virus Infection. BIOMED RESEARCH INTERNATIONAL 2017; 2017:9679843. [PMID: 28512640 PMCID: PMC5420426 DOI: 10.1155/2017/9679843] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/29/2016] [Revised: 03/21/2017] [Accepted: 04/02/2017] [Indexed: 12/24/2022]
Abstract
Hepatitis B virus (HBV) infection is the predominant risk factor for chronic hepatitis B (CHB). The association between HBV infection and human leukocyte antigen- (HLA-) DQ polymorphism (rs2856718 and rs7453920) has been demonstrated in other studies; however, the results were controversial or inconclusive. Therefore, to derive a more precise estimation of the association, a meta-analysis was performed. Crude odds ratios (ORs) and their 95% confidence intervals (CIs) were used to assess the strength of association between HLA-DQ polymorphism (rs2856718 and rs7453920) and HBV infection risk. A total of 11 articles were used to evaluate the effect of the two polymorphisms on risk of HBV infection. The pooled data showed that HLA-DQ rs2856718-G polymorphism showed protection against HBV infection, and rs2856718-A was a risk factor for chronic HBV infection. The pooled risk estimates indicated that HLA-DQ rs7453920-A polymorphism was associated with decreased risk of HBV infection, and rs7453920-G serves as a risk factor in HBV infection. However, these stratified analyses were lacking credibility due to the limitation of correlational study numbers; further investigation on a large population and different ethnicities is warranted.
