ABSTRACT

Objective @#To investigate the prevalence of hepatitis B virus ( HBV ) infection among volunteer blood donors in Hangzhou City, and to evaluate the residual risk of transfusion-transmitted HBV infections. @*Methods @#Data pertaining to volunteer blood donors in Hangzhou City from 2016 to 2019 were retrieved from the blood donor management system. Hepatitis B surface antigen ( HBsAg ) was detected by enzyme-linked immunosorbent assay ( ELISA ) and HBV DNA was detected using nucleic acid testing. The incidence/window period model was employed to assess the residual risk of HBV transmitted through transfusion from donors. @*Results @#The prevalence of HBV infections was 0.56% among the 320 755 first-time donors and 0.13% among the 279 816 repeat donors in Hangzhou City from 2016 to 2019, and a higher prevalence of HBV infection was detected among first-time donors than among repeat donors ( P<0.05 ). The residual risks of transfusion-transmitted HBV infection were 296.38 per million person-times ( 95%CI: 277.57 to 315.19 per million person-times ) and 98.79 per million person-times ( 95%CI: 87.15 to 110.43 per million person-times ) among first-time and repeat donors with positive HBsAg, and were 86.79 per million person-times ( 95%CI: 76.60 to 96.98 per million person-times ) and 28.93 per million person-times ( 95%CI: 22.63 to 35.23 per million person-times ) among first-time and repeat donors tested positive for HBV DNA, respectively.@*Conclusions @#There is still a residual risk of HBV infection transmitted through transfusion from blood donors in Hangzhou City. Nucleic acid testing may remarkably reduce the residual risk of transfusion-transmitted HBV infection in blood donors.

ABSTRACT

Objective To investigate the status of hepatitis B virus (HBV) infection in children in Wuhan, and to analyze the expression pattern and distribution of serum markers. Methods Five serum markers of HbsA, HbsAb, HbeAg, HbeAb and HBcAb were detected by electrochemiluminescence immunoassay in 67 027 children aged 0-18 years including inpatients, outpatients, and physical examinees in Wuhan Children's Hospital. SPSS24.0 statistical software was used to analyze the results by age and gender. Results The “all negative” detection rate of all 67,027 children was 18.98%. There was a significant difference in the positive rate of HBcAb between male and female. The positive rate of HBcAb was higher in 0~28 days and 1~12 months group and decreased significantly after 1 year old. The positive rate of HBcAb was 5.02% in 1-14 years old but increased slightly in 15-18 years old. Among HBsAb positive children, the positive rate of HBsAb reached the peak of 95.65% in 1~2 years old group and the lowest of 68.90% in 6~14 years old group, and gradually decreased before 15 years old. Among the children with HBsAb concentration ≥100 IU/L, the proportion of 1~2 years old group was the highest (76.99%), and the proportion of 6~14 years old group was the lowest (40.99%). A total of 20 HBsAb serum marker expression patterns were detected, and the detection rates of “single HBsAb+”, “all negative”, “HBsAb+/HBcAb+”, and “HBsAb+/HBeAb+/HBcAb+” were 71.40%, 18.98%, 4.80% and 4.20%, respectively. Among them, 11 kinds of uncommon expression patterns were detected, and 9 kinds of uncommon expression patterns were detected in neonates, with a detection rate of 1.21%, which was higher than that in other age groups. Among all serological patterns, only the detection rate of “single HBcAb+” showed a statistical difference between male and female. Conclusion The HBV infection rate in all ages of 0~18 years old children in Wuhan is low. “Single HBsAb+” is the main serological pattern, and the concentration distribution of HBsAb is mostly in the range of 100-999 IU /L. There is a high “all negative” detection rate. School-age children should be inoculated with hepatitis B vaccine, which may be beneficial to reduce the risk of infection.

ABSTRACT

Resumen Introducción: La identificación de portadores del virus de la hepatitis B en donantes de sangre es imperativo para evitar la transmisión de la enfermedad a través de transfusiones sanguíneas. Objetivo: Determinar si los donantes de sangre con resultados positivos de los marcadores serológicos HbsAg y anti-HBc eran portadores de ADN del virus de la hepatitis B. Métodos: Se recolectaron 12 745 muestras de seis bancos de sangre ecuatorianos, las cuales fueron analizadas con pruebas serológicas para identificar los marcadores infecciosos HBsAg, anti-HBc, anti-HBs mediante prueba ELISA automatizada. Todas las muestras positivas para uno, dos o los tres marcadores fueron analizadas con técnica molecular para determinar la presencia de ADN viral. Resultados: Se identificó que 27.5 % de las muestras reactivas solo a anti-HBc y 100 % de las muestras con resultados positivos de HBsAg/anti-HBc-IgM/IgG presentaron ADN del virus de la hepatitis B (p = 0.001). Conclusiones: La elección de los marcadores de infección y los métodos de detección definen los resultados. Es importante la realización de dos pruebas serológicas y una molecular para identificar a los portadores del virus de la hepatitis B y evitar su transmisión.


Abstract Introduction: Identification of hepatitis B virus carriers in blood donors is imperative in order to avoid transmission of the disease via blood transfusion. Objective: To determine if blood donors with positive results for serological markers HBsAg and anti-HBc were hepatitis B virus DNA carriers. Methods: 12,745 samples were collected from six Ecuadorian blood banks and analyzed for HBsAg, anti-HBc and anti-HBs infectious markers by automated ELISA. All samples that tested positive for one, two or all three markers were analyzed with molecular techniques to determine the presence of viral DNA. Results: 27.5 % of the samples that were reactive for anti-HBc alone and 100 % of those with positive results for HbsAg and IgM/IgG anti-HBc were identified to contain hepatitis B virus DNA (p = 0.001). Conclusions: The selection of infection markers, as well as the detection methods define the results. Performing two serological and one molecular test is important in order to identify hepatitis B virus carriers and prevent its transmission.

ABSTRACT

The JAK/STAT/SOCS signaling pathway can mediate a variety of cytokines involved in inflammation, tumor, and autoimmune diseases and it also plays an important role in hepatitis B virus (HBV) infection-related liver diseases. This article briefly reviews the structure and signal pathway regulation of JAK-STAT and SOCS and elaborates on their role in the development and progression of HBV-related chronic hepatitis B, liver cirrhosis, liver failure, and hepatocellular carcinoma. The final analysis shows that the JAK/STAT/SOCS signaling pathway is dysregulated in HBV-related liver disease and is involved in the development and progression of the disease, and it may even influence the treatment and prognosis of the disease.

ABSTRACT

The incurable chronic infection caused by hepatitis B virus (HBV) is the major health burden worldwide. Covalently closed circular DNA (cccDNA) exists in the nucleus of infected cells as a stable minichromosome, and when a new therapy realizes inactivation or eliminates persistent cccDNA in infected hepatocytes, the natural process of chronic infection and long-term antiviral therapy will no longer exist. This article introduces the methods targeting cccDNA, such as gene editing and epigenetic modification, so as to achieve the complete cure of HBV infection.

ABSTRACT

ObjectiveTo investigate the value of serum protoporphyrin IX (PPIX) measurement in evaluating liver damage in patients with HBV-related chronic liver diseases. MethodsA total of 110 patients who were diagnosed with HBV-related chronic liver diseases in The First Affiliated Hospital of Xi’an Medical University from October 2018 to October 2019 were enrolled as case group [chronic hepatitis B (CHB) group with 50 patients, liver cirrhosis (LC) group with 40 patients, and hepatocellular carcinoma (HCC) group with 20 patients], and 40 healthy individuals were enrolled as control group. High-performance liquid chromatography was used to measure serum PPIX. A one-way analysis of variance was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test or the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups; the receiver operating characteristic (ROC) curve was plotted to analyze diagnostic value; a Spearman correlation analysis was also performed to investigate correlation. ResultsThe CHB, HC, and HCC groups had a significantly higher level of PPIX than the control group [44.29 (25.99-85.36) ng/dl, 72.73 (48.28-90.43) ng/dl, and 91.79 (68.34-121.52) ng/dl vs 15.43 (10.87-20.16) ng/dl, all P<0.05], and the patients with decompensated LC had a significant increase in the level of PPIX compared with those with compensated LC [54.50(29.14~85.65) vs 76.09(53.47~104.37),Z=-2.176, P<0.05]. PPIX had a sensitivity of >85% and a specificity of >60% in the diagnosis of CHB, LC, and HCC. The patients in the latent stage of CHB had a significantly higher level of PPIX than those in the control group (Z=-4.303, P<0.05). In the patients with LC, PPIX was moderately positively correlated with total bilirubin (TBil) (rs=0.587, P<0.05) and moderately negatively correlated with albumin (rs=-0.408, P<0.05); in the patients with HCC, PPIX was moderately positively correlated with TBil (rs=0.470, P<0.05) and moderately negatively correlated with cholinesterase (rs=-0.459, P<0.05). ConclusionElevated serum PPIX is an early event of liver damage in patients with HBV-related chronic liver diseases and can thus be used as a sensitive parameter for the early warning and assessment of liver damage.

ABSTRACT

ObjectiveTo investigate the value of Model for End-Stage Liver Disease (MELD) score combined with platelet-to-white blood cell ratio (PWR) in predicting the short-term prognosis of patients with hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). MethodsA retrospective analysis was performed for the clinical data of 123 HBV-ACLF patients who were admitted to The First Affiliated Hospital of Suzhou University from June 2014 to June 2019, and according to the prognosis on day 90 after admission, these patients were divided into survival group with 53 patients and death group with 70 patients. Related clinical data were recorded, including age, sex, and total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), serum creatinine (SCr), Albumin (Alb), prealbumin (PAB), international normalized ratio (INR), white blood cell count (WBC), lymphocyte count (LY), monocyte count (MO), neutrophil count (NE), hemoglobin (Hb), and platelet count (PLT) within 24 hours after admission, and PWR and MELD score were calculated. The t-test and the Mann-Whitney U test were used for comparison of continuous data between two groups; univariate and multivariate binary logistic regression analyses were used to analyze the association between each factor and the prognosis of HBV-ACLF; a predictive model of MELD score combined with PWR was established. The receiver operating characteristic (ROC) curve was plotted, and Youden index, cut-off value, sensitivity, and specificity were calculated; the area under the ROC curve (AUC) was calculated for MELD score alone or combined with PWR to compare their value in predicting the prognosis of HBV-ACLF patients. ResultsThere were significant differences between the two groups in TBil, ALT, SCr, INR, WBC, MO, NE, Hb, PLT, PWR, and MELD score (all P<0.05). TBil, SCr, INR, WBC, MO, NE, and MELD score were risk factors for prognosis of HBV-ACLF patients(all P<0.05); PWR (odds ratio [OR]=0.883, 95% confidence interval [CI]: 0.798-0.977, P=0.016) and MELD score (OR=1.442, 95%CI: 1.225-1698, P<0.001) were independent predictive factors for the prognosis of HBV-ACLF patients. MELD score combined with PWR had a stronger predictive efficiency than MELD score alone in predicting the prognosis of HBV-ACLF patients [0.895 (95%CI: 0.827-0943) vs 0.842 (95%CI: 0.765-0.902), P<0.05]. ConclusionMELD score combined with PWR can improve the efficiency of MELD score alone in predicting the prognosis of HBV-ACLF patients.

ABSTRACT

Chronic hepatitis B (CHB) is a major global public health issue, and although direct-acting antiviral agents can control hepatitis B virus (HBV) replication, it is difficult to achieve the cure of CHB. Host adaptive immune response plays a key role in eliminating HBV, and it is expected to achieve the functional cure of CHB by rebuilding the patient’s adaptive immunity. Great progress has been made in therapeutic vaccines, cellular immunotherapy, immune checkpoint blockade, T cell metabolic reprogramming, and strategies of neutralizing antibody targeting adaptive immunity for the treatment of hepatitis B. This article summarizes the above-mentioned therapies for hepatitis B in recent years.

ABSTRACT

For the ideal preclinical animal model of hepatitis B virus (HBV), its hepatocytes should allow HBV entry and cccDNA generation and have both innate and adaptive immune systems. However, HBV only naturally infects humans and chimpanzees due to highly restricted species specificity, and no effective model has been established so far to truly reflect the immune mechanism and pathogenesis of HBV infection. This article reviews five commonly used mouse models, i.e., HBV transgenic model, HBV plasmid DNA hydrodynamic injection model, AAV-HBV transfection model, cccDNA surrogate model, and human-mouse chimeric liver model, and looks forward to the new models that will appear in the future, such as hNTCP transgenic cynomolgus monkey, rhesus monkey, or pig models, so as to provide a reference for researchers to select these models, accelerate the process of drug screening, validate new therapies, and better solve the problems of HBV biological pathogenesis.

ABSTRACT

ObjectiveTo investigate the change in the activity of glucosylceramide synthase, the key enzyme in glycosphingolipid metabolism and synthesis, in Huh7 cells infected by hepatitis B virus (HBV) in vitro. MethodsBlood samples were collected from nine previously untreated patients with acute hepatitis B who attended Department of Infectious Diseases, The First Hospital of Lanzhou University, from June to August, 2019, and the blood samples collected from seven healthy individuals who underwent physical examination were established as control. Huh7 cells were inoculated with the high-copy HBV particles (>9.9×107 IU/ml) in the serum of patients with HBV infection (infection group), and Huh7 cells co-cultured with the serum of healthy individuals were established as control group. The expression levels of HBsAg and HBV DNA in the cytoplasm of HBV-infected Huh7 cells were measured, and the correlation between GCS activity and virus was analyzed. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups, and a Pearson correlation analysis was performed. ResultsCompared with the control group, the infection group had a significant reduction in the number of cells, an increase in cell volume, and cell membrane fragmentation. The infection group had a significant increase in the expression of HBsAg in cytoplasm at 4 hours, 8 hours, 2 days, and 5 days after infection (P<0.05); the expression level of HBV DNA tended to increase significantly from 4 hours after infection to 8 hours, 2 days, and 5 days after infection (16.67±11.55 IU/ml vs 112.01±25.94 IU/ml/328.01±10350 IU/ml/101.60±49.84 IU/ml, P<0.001), with the highest level at 2 days after infection. During HBV infection, the activity of GCS gradually increased with the increase in viral replication from 4 hours after infection (126.21±9.59 IU/ml) and reached a peak at 2 days after infection (226.53±36.27 IU/ml), with a significant difference between the infection group and the control group at 2 days after infection (226.53±36.27 IU/ml vs 136.50±1544 IU/ml, t=3.956, P=0.016 7). The activity of GCS was positively correlated with HBV DNA level (r=0.576 8, P=0047 1). ConclusionHuh7 cells are successfully infected with the high-copy HBV particles in the serum of patients with HBV infection, which mimics the characteristics of HBV infection in vitro to a certain degree. The activity of GCS may be associated with HBV infection, suggesting that glycosphingolipid synthesis and metabolism may be closely associated with HBV.

ABSTRACT

Hepatitis B virus (HBV) infection is a major public issue in the world. Although currently used antiviral drugs can effectively control virus replication, they cannot clear HBV and HBV reactivation is still observed after the withdrawal of anti-HBV drugs. Meanwhile, experimental studies and clinical research have shown that after HBV infection, although 95% of the adult patients can achieve clinical cure spontaneously, virus genome still exists in host hepatocytes, and when immunosuppressants or chemotherapeutic drugs are used for the treatment of underlying diseases such as solid tumor, hematological malignancies, rheumatic immune diseases, and HCV infection, HBV replication might be reactivated. HBV reactivation may lead to severe clinical outcomes, and some patients may experience liver failure or even death. Retrospective studies in China show that 9%-30% of the cases of acute-on-chronic hepatitis B liver failure are caused by HBV reactivation, and therefore, it is of great importance to identify the population at risk of HBV reactivation and develop reasonable preventive measures, which may help to reduce the development of acute-on-chronic hepatitis B liver failure. This article reviews the definition and basis of HBV reactivation, elaborates on the predisposing factors and mechanism of HBV reactivation in inducing liver failure, and summarizes the population requiring prevention and related preventive measures.

ABSTRACT

The kidney plays a key role in hepatitis B virus (HBV) infection of liver cells. The pathogenesis of HBV-associated glomerulonephritis (HBV-GN) remains unclear, and the mechanism of HBV directly causing the injury of renal tubules has been taken seriously in recent years. HBV can induce the apoptosis of renal tubular cells by regulating cell cycle and activating related signaling pathways including NF-κB and thus lead to the progression of HBV-GN. At present, there are still no drugs targeting the kidney in the treatment of HBV-GN. This article summarizes the research advances in the key factors for HBV infection of cells and the injury of renal tubular cells caused by HBV and elaborates on the possible mechanism of direct infection of renal tubular cells by HBV, so as to provide new ideas for the treatment of HBV-GN.

ABSTRACT

ObjectiveTo investigate the role of coagulation function parameters and platelet indices in thrombotic events in patients with hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). MethodsA total of 56 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2019 were enrolled and divided into thrombotic complication (TC) group with 24 patients and non-thrombotic complication (NTC) group with 32 patients. A retrospective analysis was performed for their general clinical data on admission, and the patients were observed in terms of the changes in coagulation function, platelet count (PLT), and the platelet function-related index mean platelet volume (MPV) on days 1-7 after admission. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A repeated measures analysis of variance was used to compare coagulation markers within and between groups at different time points. ResultsOn admission, the TC group had a significantly younger age than the NTC group [31.5 (29.0-34.0) years vs 48.5 (36.0-50.7) years, Z=-2.637, P=0.008]. On the day of admission, there was no significant difference in MPV between the TC group and the NTC group (P >0.05), while on days 2-7 after admission, there was a significant difference in MPV between the two groups (t=-2.696、-2.742、-2.894、-4.174、-3.945、-4.716,all P <0.01). In the TC group, MPV reached the peak value on day 5 of admission, with a mean value of 13.90±1.12 fl, which was higher than the range of normal values. On admission, all patients had a mean prothrombin time (PT) of 28.8±7.2 s, a mean activated partial thromboplastin time (APTT) of 50.5±8.7 s, and a mean international normalized ratio (INR) of 2.6±0.7, which were higher than normal values; all patients had a mean fibrinogen (Fb) level of 1.16±0.3 g/L and a mean PLT of (107.7±26.5)×109/L, which were lower than normal values. There were no significant differences in PT, APTT, Fb, INR, and PLT between the TC group and the NTC group (all P >0.05). ConclusionCoagulation disorder in patients with liver failure is more of a low-equilibrium state, which is complex and heterogeneous and requires individualized treatment. For patients with HBV-ACLF, the development of thrombotic events may be more associated with platelet function than PLT or conventional coagulation markers.

ABSTRACT

Patients with chronic hepatitis B (CHB) often have immune-mediated liver injury, and it is considered that the interaction between viral infection and immune response is an important cause of disease progression. CHB can progress to liver fibrosis, liver cirrhosis, and even hepatocellular carcinoma (HCC). This article reviews the discovery of T helper 17 (Th17) cells and regulatory T (Treg) cells, describes their own features, and elaborates on their role and mechanism of action in maintaining the stability of the immune system. This article also analyzes the role of Th17/Treg cell imbalance in CHB, liver fibrosis, liver cirrhosis, and HCC and points out that Th17/Treg cell imbalance may promote the aggravation of HBV-related liver diseases.
