Abstract

(1) Background: Despite the advantages of COVID-19 vaccination, rare cases of acute hepatitis developing after the administration of the COVID-19 vaccine or the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported. The aim of the study is to describe a case series of patients who experienced the onset of acute hepatitis, with or without autoimmune features, following SARS-CoV-2 vaccination or infection and to hypothesize a genetic susceptibility in the pathogenesis. (2) Methods: A group of patients with acute onset hepatitis following SARS-CoV-2 vaccination or infection were evaluated in our hepatology outpatient clinic, where they underwent biochemical and autoimmune tests. Hepatitis A (HAV), B (HBV), and C virus (HCV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human immunodeficiency virus (HIV) infections were excluded. Patients with a diagnosis of autoimmune hepatitis (AIH) or drug-induced liver injury (DILI) underwent HLA typing and histological testing. (3) Results: Five patients experienced new-onset AIH after COVID-19 vaccination, one of which developed mild symptoms after vaccination that strongly worsened during subsequent SARS-CoV-2 infection. One patient had AIH relapse after COVID-19 vaccination while on maintenance immunosuppressive treatment. All of them had HLA DRB1 alleles known to confer susceptibility to AIH (HLA DRB1*03,*07,*13,*14), and in three of them, HLA DRB1*11 was also detected. Two patients developed acute hepatitis without autoimmune hallmarks which resolved spontaneously, both positive for HLA DRB1*11. (4) Conclusions: An association between AIH and COVID-19 vaccine or infection can be hypothesized in individuals with a genetic predisposition. In patients without autoimmune features and spontaneous improvement of hypertransaminasemia, the diagnosis of drug-induced liver injury (DILI) is probable. Further studies are needed to determine the presence of an actual association and identify a possible role of HLA DRB1*11 in the pathogenesis of acute liver injury after SARS-CoV2 vaccination or infection.

Abstract

The presence of polymorphisms in the human leukocyte antigen (HLA)-DQB1 gene, along with its expression, has been demonstrated to be correlated with spontaneous clearance and susceptibility to HBV infection. The present study aimed to evaluate the possible role of genetic polymorphisms in HLA-DQB1 in three generations of patients with chronic hepatitis B (CHB). Based on the inclusion criteria, 90 CHB patients, 18 individuals recovered from HBV infection, and 40 healthy subjects were chosen. The DNA contents of the whole blood samples were extracted in order to perform HLA-DQB1 typing by the PCR technique. Besides whole blood samples, sera were applied to measure liver function tests (LFTs), as well as the titers of anti-HDV and anti-HCV. Also, in all CHB patients were measured liver stiffness (LSM) by Fibro Scan. The results of HLA-DQB1 polymorphisms (rs2856718 and rs7453920) demonstrated that the majority of polymorphisms in CHB patients were HLA-DQB1*03, HLA-DQB1*05, HLA-DQB1*04:01 and HLA-DQB1*03:01 that associated with HBV persistence and chronicity. Among the patients who showed these polymorphisms, the mean±SD, LSM was 4±1.57 KPa and most of them, F grade was reported as F2, which was a sign of disease progression towards chronicity. HLA polymorphisms imputation revealed that HLA-DQB1*06:04 (3.4%, P-Value= 0.2) was detected only in healthy subjects as protective polymorphism, while the allele HLA-DQB1*03:03 was reported in both healthy subjects (P-Value= 0.06) and recovered patients (P-Value= 0.1) as suppressor of CHB formation. The allele HLA-DQB1*05:02 was found in both healthy subjects (3.4%) and CHB patients (4.5%) which was associated with risk to liver cirrhosis (P-Value= 0, OR: 0.002 0.95CI: 0.000-0.15). HLA polymorphism analysis indicated that 17.39% of patients who were seropositive for anti-HCV carried the HLA-DQB1*03:01. HBV resistance or infection risk could be assessed by DBQ1 typing. The existence of polymorphisms in HLA gene could influence the clearance (HLA-DQB1*03:03) or susceptibility and persistence of infection (HLA-DQB1*03, HLA-DQB1*05, HLA-DQB1*04:01 and HLA-DQB1*03:01). These results have the potential to improve personalized therapy and prognosis for HBV infection.

Abstract

Background and aims

Genetic polymorphisms within the promoter of interferon-α receptor type-1 (IFNAR1) have been associated with the susceptibility to and the outcome of chronic hepatitis B virus (HBV) infection. However, the impact of these polymorphisms in the transcriptome of the HBV-associated hepatocellular carcinoma (HCC) remains largely unexplored.

Using whole-genome and exome sequencing data from The Cancer Genome Atlas project, we characterized three single-nucleotide polymorphisms (SNPs: −568G/C, −408C/T, −3C/T) and one variable number tandem repeat [VNTR: −77(GT)n] within the IFNAR1 promoter sequence in 49 HCC patients. RNAseq data from 10 genotyped HCC samples were grouped according to their −77VNTR or −3SNP genotype to evaluate the impact of these polymorphisms on the differential expression on the HCC transcriptome.

Results

There is a fourfold higher impact of the −77VNTR on the HCC transcriptome compared to the −3SNP (q < 0.1, p < 0.001). The expression of the primary IFNAR1 transcript is not affected by these polymorphisms but a secondary, HCC-specific transcript is expressed only in homozygous −77VNTR ≤8/≤8(GT)n samples (p < 0.05). At the same time, patients carrying at least one −77VNTR >8(GT) allele, presented a strong upregulation of the fibronectin-1 (FN-1) gene, which has been associated with the development of HCC. Gene Ontology and pathway enrichment analysis of the differentially expressed genes revealed a strong disruption of the PI3K–AKT signaling pathway, which can be partially triggered by the extracellular matrix FN-1.

Conclusion

The IFNAR-1 promoter polymorphisms are not involved in the expression levels of the main IFNAR-1 transcript. The −77VNTR has a regulatory role on the expression of a secondary, truncated, HCC-specific transcript, which in turn coincides with disruptions in cancer-associated pathways and in FN-1 expression modifications.

Abstract

Single-nucleotide polymorphisms in the human leukocyte antigen (HLA)-DQB1 gene are associated with chronic inflammatory and immunological diseases. Host genetic factors have a key role in the development of chronic hepatitis B (CHB). The aim of the present study was to investigate the association between the HLA-DQB1 polymorphisms and the susceptibility to CHB. PubMed, Embase, CNKI and Wanfang databases were searched for the studies that reported the association of the HLA-DQB1 polymorphisms with CHB between January 1, 1966 and July 30, 2015. HLA-DQB1 polymorphism-specific odds ratio (OR) and 95% confidence intervals (95% CI) were pooled and calculated in the fixed effects model using the Mantel-Haenszel method. Q-test and I² test were performed to examine the heterogeneity. Begg's funnel test and Egger's test were conducted to assess publication bias. All the statistical tests were two-tailed. Subsequent to searching the databases and screening according to the inclusion criteria, 7 case-control studies were available in the present meta-analysis, including 815 CHB patients and 731 control subjects for the HLA-DQB1 polymorphisms. In conclusion, the statistically significant pooled OR of the HLA-DQB1 polymorphisms were obtained for the HLA-DQB1 loci (*0201, case vs.

CONTROL

I²=36.5%; P-value of heterogeneity=0.15; OR, 1.29; 95% CI, 1.02-1.64; P=0.0301; *0301, case vs.

CONTROL

I²=0%; P-value of heterogeneity=0.899; OR, 1.37; 95% CI, 1.12-1.69; P=0.002; *0502, case vs.

CONTROL

I²=24.9%; P-value of heterogeneity=0.239; OR, 1.50; 95% CI, 1.02-2.20; P=0.04), which were associated with an increased risk of CHB. Similar significant results were observed and acquired in the following HLA-DQB1 loci (*0303, case vs.

CONTROL

I²=0%; P-value of heterogeneity=0.986; OR, 0.77; 95% CI, 0.62-0.95; P=0.017; *0604, case vs.

CONTROL

I²=0%; P-value of heterogeneity=0.594; OR, 0.38; 95% CI, 0.20-0.74; P=0.003), which were associated with a decreased risk of CHB. No significant association was observed for the other HLA-DQB1 family loci. The present meta-analysis demonstrated that the HLA-DQB1 loci (*0201, *0301 and *0502) polymorphisms were significantly associated with an increased risk of CHB. However, HLA-DQB1 loci polymorphisms (*0303 and *0604) were associated with a decreased risk of CHB. These results support the hypothesis that polymorphisms of the HLA-DQB1 allele families may affect the susceptibility or resistance to CHB.

Abstract

Recent genome-wide association studies have revealed the HLA region on chromosome 6p21 as a susceptibility locus for hepatitis B virus (HBV) infection, a finding subsequently replicated in independent samples. However, only limited single nucleotide polymorphisms (SNPs) were analyzed in most of these studies, and it remains to be determined which SNPs contribute to the detected association. After genotyping 140 SNPs within this genomic region in a total of 1657 HBV-positive patients and 1456 HBV-negative controls, we conducted a series of genetic epidemiological and bioinformatics analysis, including individual SNP-based association analysis, haplotype-based association analysis, and conditional analysis. We identified 76 SNPs and 5 LD blocks in HLA-DP/DQ clusters that are significantly associated with HBV infection, with the smallest P value being 3.88 × 10(-18) for rs9277535 in HLA-DPB1. With conditional analysis, we further revealed that the genes contributing to the effects of variants in HLA-DP/DQ on infection are independent of each other, and the LD block 5 in the 3'-UTR region of HLA-DPB1 had a predominant effect in the association of HLA-DP with HBV infection. We also found that the SNPs in the 3'-UTR region of HLA-DPB1 were significant between the subgroups of inactive HBV carrier, chronic hepatitis B, or hepatic cirrhosis from the case group and the spontaneous HBV-clearance subgroup from the control group. Finally, we did further association analysis of SNPs in this region with different subgroups from the case group, which revealed no association of these SNPs with the progression of HBV-related diseases. In sum, we showed, for the first time, that the HLA-DP/DQ clusters contribute independently to HBV infection, and the 3'-UTR region of HLA-DPB1 represents an important functional region involved in HBV infection.

Abstract

BACKGROUND

The aim of this study was to explore the correlation of gene polymorphisms of human leukocyte antigen-DQB1 (HLA-DQB1) with the infection outcome and replication status of hepatitis B virus (HBV) positive patients in the Xinjiang Uygur population in China.

METHODS

110 cases of chronic hepatitis B (CHB) of Xinjiang Uygur were examined clinically, which were named as the CHB group; 100 cases carrying chronic HBV (ASC) served as ASC group; 80 cases of self-limited HBV infection (RHBS) were recorded as RHBS group. Genotypes of HLA-DQB1 were detected by sequence specific primer-polymerase chain reaction (PCR-SSP) method, and the differences of gene frequency among groups were also compared. The distribution frequencies of the HLA-DQB1 gene under different replication states of HBV were compared.

RESULTS

The distribution frequency of DQB1*0201 in the RHBS group was higher than that of the ASC group (18.75%, 10.50%, χ(2) = 5.959, P < 0.05, OR = 2.257). The distribution frequency of DQB1*0201 in the CHB group was higher than that of the ASC group (17.73%, 10.50%, χ(2) = 5.363, P < 0.05, OR = 2.066). The distribution frequency of DQB1*0301 in the CHB group was higher than that of the ASC group (26.82%, 16.50%, χ(2) = 9.062, P < 0.05, OR = 2.349). The distribution frequency of DQB1*0303 in the CHB group was lower than that of the ASC group (19.55%, 31.00%, χ(2) = 10.996, P < 0.05, OR = 0.393). There was no statistically significant difference in the allele frequencies among all other groups. The distribution frequency of DQB1*0201 in the low replication group was higher than that of the high replication group (17.08%, 10.56%, χ(2) = 4.295, P < 0.05, OR = 1.939).

CONCLUSION

HLA-DQB1*0201 is a HBV resistance gene in Xinjiang Uygur. DQB1*0301 is correlated with continuous infection of HBV. DQB1*0303 is a susceptibility gene of ASC.

Abstract

Hepatitis B virus (HBV) infection is a leading cause of liver diseases including cirrhosis and hepatocellular carcinoma. Human leukocyte antigens (HLAs) play an important role in the regulation of immune response against infectious organisms, including HBV. Recently, several genome-wide association (GWAS) studies have shown that genetic variations in HLA genes influence disease progression in HBV infection. The aim of this study was to investigate the role of HLA genetic polymorphisms and their possible role in HBV infection in Saudi Arabian patients. Variations in HLA genes were screened in 1672 subjects who were divided according to their clinical status into six categories as follows; clearance group, inactive carriers, active carriers, cirrhosis, hepatocellular carcinoma (HCC) patients and uninfected healthy controls. Three single nucleotide polymorphisms (SNPs) belonged to HLA-DQ region (rs2856718, rs7453920 and rs9275572) and two SNPs belonged to HLA-DP (rs3077 and rs9277535) were studied. The SNPs were genotyped by PCR-based DNA sequencing (rs2856718) and allele specific TaqMan genotyping assays (rs3077, rs7453920, rs9277535 and rs9275572). The results showed that rs2856718, rs3077, rs9277535 and rs9275572 were associated with HBV infection (p = 0.0003, OR = 1.351, CI = 1.147–1.591; p = 0.041, OR = 1.20, CI = 1.007–1.43; p = 0.045, OR = 1.198, CI = 1.004–1.43 and p = 0.0018, OR = 0.776, CI = 0.662–0.910, respectively). However, allele frequency of rs2856718, rs7453920 and rs9275572 were found more in chronically infected patients when compared to clearance group infection (p = 0.0001, OR = 1.462, CI = 1.204–1.776; p = 0.0178, OR = 1.267, CI = 1.042–1.540 and p = 0.010, OR = 0.776, CI = 0.639–0.942, respectively). No association was found when polymorphisms in HLA genes were compared in active carriers versus cirrhosis/HCC patients. In conclusion, these results suggest that variations in HLA genes could affect susceptibility to and clearance of HBV infection in Saudi Arabian patients.

Abstract

BACKGROUND

Chronic hepatitis B treatment with oral antiviral drugs is a long course. During this course, antiviral resistance is a serious issue, particularly, if genetically low barrier drugs are in use. Host immunity is accepted to have an effect on antiviral resistance development. The earliest clinical sign of drug resistance is virologic breakthrough. In this study, we aimed to investigate the relation between HLA-DQB1 alleles and virologic breakthrough events.

SUBJECTS AND METHODS

The patient records at single institution hepatology clinic were reviewed. Local institution ethics committee approval was taken. The patients' demographic data, virologic parameters, treatment statues were noted. Patients who had received lamivudine or adefovir were recruited and grouped into two according to virologic breakthrough occurrence. Patients who were not compliant to the given treatment were excluded. Blood samples were taken for DNA extraction. HLA-DQB1 alleles were determined at high level by sequence-speciﬁc primers-polymerase chain reaction. The distribution of DQB1 alleles among groups was analyzed.

RESULTS

One hundred ninety-eight patients were eligible for the study. Ninety-six of them had virologic breakthrough where 102 did not have. DQB1 0503 allele was more frequent in patients without breakthrough (28.4% vs. 12.4%, P=0.006). In univariate analysis, HBeAg seropositivity (P<0.001), absence of cirrhosis (P=0.007), younger age (P=0.002) and higher pretreatment logDNA (P<0.001) were related to breakthrough events. However, in multivariate analysis only logDNA (P<0.001) and DQB1*0503 (P=0.02) allele revealed statistically significant relation with breakthrough events.

CONCLUSION

Host immunity may have an effect on outcome during treatment with oral antiviral drugs. A patient with better immunologic profile may suppress the viral replication better and this may cause less resistance occurrence during treatment with genetically low barrier drugs.

Abstract

BACKGROUND

In Greenland, the prevalence of hepatitis B surface antigen carriers, reflecting chronic hepatitis B virus (HBV) infection, is 5%-10%. However, the incidence of cirrhosis and hepatocellular carcinoma in this population has been reported to be low. We investigated this discrepancy in a large population-based cohort study.

METHODS

In total, 8879 Greenlanders (16% of the population) were recruited for population-based surveys performed from May 5 to July 7, 1987, and from November 1 to November 21, 1998, with follow-up until March 31, 2010. HBV status was based on serological testing, supplemented by data from all available HBV registries in Greenland to determine changes in HBV status over time. Information on morbidity and mortality was obtained from the Patient Discharge Registry, the Cancer Registry, and the Central Registration System. Sex, age, ethnicity, and period-adjusted incidence rate ratios (IRRs) were estimated using Poisson regression. World standardized rates were derived from these and World Health Organization data.

RESULTS

The 650 chronically HBV-infected persons had higher rates of hepatocellular carcinoma (adjusted IRR = 8.70; 95% CI = 2.06 to 36.7), liver disease (adjusted IRR = 5.73, 95% CI = 3.52 to 9.34), and all-cause mortality (adjusted IRR = 1.47; 95% CI = 1.21 to 1.79) than the 5160 HBV-negative persons. However, the world standardized incidence rates of hepatocellular carcinoma (38.5 cancers per 100 000 person-years) and cirrhosis (24 cases per 100 000 person-years) among chronically HBV-infected persons were low compared with results from population-based studies from countries with low, intermediate, and high rates of endemic HBV infection.

CONCLUSION

The relatively low incidence of hepatocellular carcinoma and other HBV-related morbidity among chronic HBV-infected persons in Greenland suggest a more benign course of HBV among the Greenlandic Inuit than in populations in other parts of the world.

Abstract

Hepatitis B virus (HBV) infection is a major public health problem worldwide. The mechanism of susceptibility to chronic persistent HBV infection is not well clarified, while the outcome of HBV infection mainly depends on the host immune response. Human leukocyte antigen (HLA) class II molecule is an integral component of the immune response on which majority of host genetic studies have concentrated. Many different HLA class II alleles have been demonstrated to play roles in HBV infection. In this study, the association between HBV infection and HLA-DRB1 alleles in Han individuals in northwestern China was studied for the first time. Two hundred and fifty Shaanxi Han individuals were categorized into three different groups: the HBV-infected patient group (n = 108), the spontaneously cleared control group (n = 108) and the unexposed group (n = 34). DRB1*04, DRB1*09, DRB1*12 and DRB1*15 were the most common genotypes in all the groups. The allele frequencies of HLA-DRB1*03 [10.6% of HBV-infected patients vs 3.7% of spontaneously cleared controls, odds ratios (OR) = 3.10, Pc = 0.008, P < 0.05] and HLA-DRB1*07 (17.6% of HBV-infected patients vs 9.3% of spontaneously cleared controls, Pc = 0.016, OR = 2.09, P < 0.05) were markedly higher in the HBV-infected group. But the allele frequencies of HLA-DRB1*15 (6.9% of HBV-infected patients vs 13.4% of spontaneously cleared controls Pc = 0.039, OR = 0.48, P < 0.05) were obviously lower than that of the spontaneously cleared controls. The above data indicate that HLA-DRB1*03 and HLA-DRB1*07 are related to susceptibility to chronic HBV infection, and DRB1*15 is negatively related to persistence to chronic HBV infection among people in northwestern China. Similar results were got for DRB1*03 and 15 alleles between the HBV-infected patients (n = 108) and 46 HBV seronegative spouses of the HBV patients, who were high-risk group for HBV infection. The above results suggest that host HLA class II gene is an important factor in determination of the outcome of HBV infection.

Abstract

Hepatitis B (HBV) and hepatitis C (HCV) viral infection or co-infection leads to risk of development of chronic infection, cirrhosis and hepatocellular carcinoma (HCC). Immigration and globalization have added to the challenges of public health concerns regarding chronic HBV and HCV infections worldwide. The aim of this study is to review existing global literature across ethnic populations on HBV and HCV related human leukocyte antigen (HLA) associations in relation to susceptibility, viral persistence and treatment. Extensive literature search was conducted to explore the HLA associations in HBV and HCV infections reported across global populations over the past decade to understand the knowledge status, weaknesses and strengths of this information in different ethnic populations. HLA DR13 is consistently associated with HBV clearance globally. HLADRB1*11/*12 alleles and DQB1*0301 are associated with HBV persistence but with HCV clearance worldwide. Consistent association of DRB1*03 and *07 is observed with HCV susceptibility and non-responsiveness to HBV vaccination across the population. HLA DR13 is protective for vertical HBV and HCV transmission in Chinese and Italian neonates, but different alleles are associated with their susceptibility in these populations. HLA class I molecule interactions with Killer cell immunoglobulin like receptors (KIR) of natural killer (NK) cells modulate HCV infection outcome via regulating immune regulatory cells and molecules. HLA associations with HBV vaccination, interferon therapy in HBV and HCV, and with extra hepatic manifestations of viral hepatitis are also discussed. Systematic studies in compliance with global regulatory standards are required to identify the HLA specific viral epitope, stage specific T cell populations interacting with different HLA alleles during disease progression and viral clearance of chronic HBV or HCV infections among different ethnic populations. These studies would facilitate stage specific therapeutic strategies for clearance of HBV and HCV infections or co-infections across global populations and aid in identification of HBV-HCV combined vaccine. HLA associations of chronic HBV or HCV development with confounding host factors including alcohol, drug abuse, insulin resistance, age and gender are lacking and warrant detailed investigation across global populations.

Abstract

AIM: To investigate the polymorphism of tumor necrosis factor-a(TNF-α) gene promoters in Chinese Han people, and to clarify whether such polymorphism was associated with the outcome of hepatitis B virus infection.

METHODS: After the process of extracting genomic DNA from blood in 165 subjects who spontaneously recovered(SR) and 131 patients with chronic hepatitis B (CHB), four single nucleotide polymorphism (SNP) sites in TNF-α gene promoter marked as -238G/A, -308G/A, -857C/T and -863C/A were determined by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis.

RESULTS: Twelve different promoter genotypes were detected from all of 296 research subjects, and GG.GG.CC.CC, GG.GG.CC.CA, GG.GG.CT.CC, GG.GA.CC.CC genotypes accounted for about 85% of genotypes in these subjects. By analyzing the four promoter genotypes of TNF-α, the results showed that there were significant differences in the frequencies of GG.GG.CC.CC, GG.GG.CC.CA and GG.GA.CC·CC genotypes in TNF-α gene promoter between CHB and SR, GG.GG.CC.CC genotype carriers were at increased risk of CHB with an odds ratio of 2.15 (95% CI 1.34-3.45); While GG.GG.CC.CA and GG.GA.CC.CC genotypes carriers were at increased risk of CHB with an odds ratio of 0.48(95% CI 0.27-0.86) and 0.35 (95% CI 0.14-0.89), respectively. GG.GG.CC.CA and GG.GA.CC.CC genotypes were strongly associated with the resolution of HBV infection(χ² = 6.14, P = 0.013<0.05; χ² = 5.18, P = 0.023<0.05, respectively). Single site analysis also revealed that TNF-α gene -308G/A and -863C/A SNP sites were associated with persistent HBV infection in Chinese Han people (-308G/A site, χ² = 6.53, P = 0.011<0.05, OR=3.21; -863C/A site, χ² = 4.33, P = 0.037<0.05, OR=1.69, respectively).

CONCLUSION: There is an association between polymorphisms of the promoter region -308G/A and -863C/A of TNF-α and the resolution of HBV infection. The presence of the -308A allele (TNF-α-308GA) and /or -863A allele(TNF-α-863CA or AA) may be resistant to HBV infection, which gives some new clues to the study of pathogenesis of chronic hepatitis B.

Abstract

AIM: To study the functional states of CD14⁺ cells in peripheral blood mononuclear cell (PBMCs) by analyzing the expression of early active antigen, production of pro-inflammatory cytokines and phagocytosis with flow cytometry (FCM).

METHODS: PBMCs were isolated from 11 patients with chronic active hepatitis B and 10 healthy blood donors, and 4-color flow cytometry and gate setting techniques were applied. The percentage of CD14⁺ cells and level of CD14 antigen were tested by FCM, after gate setting with CD14, side scatter (SSC) and activation-linked surface antigen (CD69) expression rate, percentage of TNF-α producing cells, level of intro-cellular TNF-α, the percentage of phagocytes and the ability of phagocytosis were investigated.

RESULTS: The SSC mean value of CD14⁺ cell of HBV patients was higher than that of health control (P < 0.01); There were no difference between two testing groups on the percentage of CD14⁺ cells and level of CD14 antigen, however the level of CD14 antigen was positively associated with the percentage of CD14⁺ cells. CD14/69 double expression rate was significantly higher than that of control group (P < 0.01); No difference was observed on CD14/TNF-α double stain cells between testing groups; In comparison with control group, the level of cellular TNF-α in HBV group was higher (P < 0.05). In control group, the percentage of TNF-α producing cells were correlated with SSC value and number of phagocytes that expressed CD14/69. There was no difference in phagocytes that expressed CD14/69 in two groups. As compared with the control group, there was more phagocytostic CD14⁺ cells in HBV group (P < 0.01), but the mean phagocytosis amount was significantly lower in this group (P < 0.05), and the number of phagocyte was negatively correlated with the level of CD14 antigen; while the SSC value and number of TNF-αproducing cells were negatively correlated with level of CD14 antigen.

CONCLUSION: CD14⁺ cells in PBMCs from chronic active hepatitis B patients are over activated in a dysfunction stage.
