Xiong D, Cai W, Zhao W. Risk factors of HBV reactivation in leukemia patients with resolved HBV infection after allogeneic hematopoietic stem cell transplantation. Clin Res Hepatol Gastroenterol 2024; 48:102447. [PMID: 39181184 DOI: 10.1016/j.clinre.2024.102447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 08/12/2024] [Accepted: 08/14/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND The hepatitis B surface antigen (HBsAg)-negative and antibody to hepatitis B core antigen (anti-HBc)-positive patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are at risk of HBV reactivation (HBVr). METHODS To analyze the risk factors for HBVr, a total of 1,042 leukemia patients(≥18years of age), who underwent allo-HSCT from January 2016 to April 2022 in The First Affiliated Hospital of Soochow University, were enrolled in the study. Finally, 193 leukemia patients with resolved HBV infection were included into the study. RESULTS HBVr occurred in 22 patients (11.39 %), and the median time to HBVr was 24 months (with a range of 11-51months). Hepatitis flares developed in 22.73 % of patients with HBVr, and hepatic failure occurred in 1 patient. During the follow-up period, only 1(1.3 %) patient experienced HBVr among 79 patients with antiviral prophylaxis. While 21(18.42 %) patients experienced HBVr among 114 patients without antiviral prophylaxis. The cumulative incidence of HBV reactivation at 3 years was 44.4. % for anti-HBs-negative donors/recipients with a low anti-HBs titer (<100IU/L) and 7.1 % for anti-HBs-positive donors/recipients with a high anti-HBs titer (≥100IU/L) respectively. In addition, univariate and multivariate Cox regression analyses confirmed the use of rituximab as a risk factor for HBV reactivation. CONCLUSION The univariate and multivariate analyses confirmed that the anti-HBs titer in both recipients and donors are protective indicators to prevent incidence of HBVr. In addition, antiviral prophylaxis can significantly reduce the incidence of HBVr.

Hepatitis B Virus Chronic Infection in Blood Donors from Asian and African High or Medium Prevalence Areas: Comparison According to Sex. Viruses 2022; 14:v14040673. [PMID: 35458403 PMCID: PMC9029447 DOI: 10.3390/v14040673] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/16/2022] [Accepted: 03/21/2022] [Indexed: 02/07/2023] Open
Abstract
Immune control of various infectious diseases, particularly viral, was shown to be more efficient for females than males. Response to viral vaccines (HAV, HBV) was higher in females. Data on hepatitis B virus (HBV) markers accumulated over 15 years in blood donors was stratified according to sex, including HBsAg, HBV viral load and levels of anti-HBs in areas where genotypes B and C (China), genotype D (Iran, Lebanon, Tunisia) and genotype E (Ghana, Burkina Faso, Gabon) were prevalent. HBsAg was screened by either ELISA or rapid tests, anti-HBc and anti-HBs by ELISA, HBV DNA load by a standardized method across sites. In Ghanaian children less than 5 years, HBV DNA load was significantly lower in females than in males (p = 0.035). In China, Ghana, Burkina Faso and Gabon blood donors, median HBsAg prevalence was ~5% and 3% in China, ~8.5% and 4.5% in Gabon, ~16% and 11% in Burkina Faso and ~11% and 7% in Ghana for male and female donors, respectively (p < 0.001). In HBsAg+ Ghanaian blood donors, distribution and median viral load were not significantly different between sexes; occult hepatitis B infections (OBI) were significantly more frequent in males. In Chinese blood donor anti-HBc+ and anti-HBs+, anti-HBs levels tended to be higher in males but vaccinated donors’ anti-HBs+ only, while anti-HBs levels were females > males. In areas where genotypes B-E are dominant, the prevalence of chronic HBV infection (HBsAg+) seems better controlled before age 16−18 by females infected vertically or horizontally. OBIs appear considerably more frequent in men, suggesting lower efficacy of HBV infection control. Female blood donors appear significantly safer from HBV than males, and their donation should be encouraged.

Abstract
Prevalence of hepatitis B (HB) remains high among adults in insular regions of southeast China. To address this issue, large-scale HB vaccination was implemented in Putuo County of Zhoushan City in 2013. To examine the effects of this large-scale HB vaccination, a cross-sectional serological survey was conducted on two isolated islands, Putuo (intervention group) and Dinghai (control group) Counties of Zhoushan City in southeastern China five years later. The data showed lower prevalence of HBsAg and negative results for all HBV markers in the intervention group compared to the control group (4.2% and 6.0%, 20.8% and 33.0%), while the positive rate for anti-HBs and only anti-HBs were higher (68.4% and 53.4%, 47.9% and 34.3%). Therefore, large-scale adult HB vaccination could lower the HB epidemic level. However, the proportion of susceptible people who were negative for all HBV markers remained high. Hence, several additional measures to limit the spread of HBV should be taken by the government.

Estimating the proportion of people with chronic hepatitis B virus infection eligible for hepatitis B antiviral treatment worldwide: a systematic review and meta-analysis. Lancet Gastroenterol Hepatol 2020; 6:106-119. [PMID: 33197397 PMCID: PMC7801814 DOI: 10.1016/s2468-1253(20)30307-1] [Citation(s) in RCA: 108] [Impact Index Per Article: 21.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 09/08/2020] [Accepted: 09/17/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND In 2016, of the estimated 257 million people living with chronic hepatitis B virus (HBV) infection worldwide, only a small proportion was diagnosed and treated. The insufficiency of information on the proportion of people infected with HBV who are eligible for treatment limits the interpretation of global treatment coverage. We aimed to estimate the proportion of people with chronic HBV infection who were eligible for antiviral treatment worldwide, based on the WHO 2015 guidelines. METHODS In this systematic review and meta-analysis, we searched Medline, EMBASE, and the Cochrane databases from Jan 1, 2007, to Jan 31, 2018, for studies describing HBsAg-positive people in the population or health-care facilities. We extracted information from published studies using a standardised form to estimate the frequency of cirrhosis, abnormal alanine aminotransferase (ALT), HBV DNA exceeding 2000 IU/mL or 20 000 IU/mL, presence of HBeAg, and eligibility for treatment as per WHO and other guidelines as reported in the studies. We pooled proportions through meta-analysis with random effects. The study was registered with PROSPERO, CRD42020132345. FINDINGS Of the 13 497 studies, 162 were eligible and included in our analysis. These studies included 145 789 participants. The pooled estimate of the proportion of cirrhosis was 9% (95% CI 8-10), ranging from 6% (4-8) in community settings to 10% (9-11) in clinic settings. Examining the proportion of participants who had characteristics used to determine eligibility in the WHO guidelines, 1750 (10·1%) of 17 394 had HBV DNA exceeding 20 000 IU/mL, and 20 425 (30·8%) of 66 235 had ALT above the upper limit of normal. 32 studies reported eligibility for treatment according to WHO or any other guidelines, with a pooled estimate of eligibility at 19% (95% CI 18-20), ranging from 12% (6-18) for studies in community settings to 25% (19-30) in clinic settings. INTERPRETATION Many studies described people with HBV infection, but few reported information in a way that allowed assessment of eligibility for treatment. Although about one in ten of the 257 million people with HBV infection (26 million) might be in urgent need of treatment because of cirrhosis, a larger proportion (12-25%) is eligible for treatment in accordance with different guidelines. Future studies describing people with HBV infection should report on treatment eligibility, according to broadly agreed definitions. FUNDING WHO and US Centers for Disease Control and Prevention.

Abstract
Purpose: To analyze the correlation of hepatitis B virus reactivation with patient-related and treatment-related dose–volume factors and to describe the feasibility of hepatitis B virus reactivation analyzed by a normal tissue complication probability model for patients with hepatocellular carcinoma treated with radiotherapy. Materials and Methods: Ninety patients with hepatitis B virus-related hepatocellular carcinoma treated with radiotherapy were enrolled in this retrospective study and were followed from June 2009 to December 2015. Of the 90 patients, 78 had received conventional fractionation radiotherapy to a mean dose of 39.6 to 50.4 Gy and 12 patients were scheduled to receive hypofractionation. The physical doses were converted into 2 Gy equivalents for analysis. The parameters, TD50 (1), n, and m, of the Lyman-Kutcher-Burman normal tissue complication probability model were derived using maximum likelihood estimation. Bootstrap and leave-one-out were employed to against model overfitting and improve the model stability. Results: Radiation-induced liver diseases were 17.8%, hepatitis B virus reactivation was 22.2%, and hepatitis B virus reactivation-induced hepatitis was 21.1%, respectively. In multivariate analysis, the V5Gy was associated with hepatitis B virus reactivation; TD50 (1), m, and n were 32.3, 0.55, and 0.71 Gy, respectively, for hepatitis B virus reactivation. Bootstrap and leave-one-out results showed that the hepatitis B virus parameter fits were extremely robust. Conclusion: A Lyman-Kutcher-Burman normal tissue complication probability model has been established to predict hepatitis B virus reactivation for patients with hepatocellular carcinoma who received radiotherapy.

Abstract
The high prevalence of hepatitis B virus (HBV) infection and intracranial atherosclerotic stenosis (ICAS) in Asia raises the question as to whether HBV infection is associated with ICAS. To answer this question, we tested the association between HBV infection and ICAS. Totally, 3072 in-hospital subjects were retrospectively enrolled. All subjects underwent computed tomography angiography (CTA) and serological testing for HBV infection. Based on the results of CTA, all subjects were categorized into 4 groups including ICAS, extracranial atherosclerotic stenosis (ECAS), ICAS/ECAS (both ICAS and ECAS), and normal. HBV infection was divided into 4 patterns including hepatitis B core antibody (anti-HBc) positive/hepatitis B surface antigen (HBsAg) positive, anti-HBc-positive/HBsAg-negative, anti-HBc-negative/HBsAg-positive, and anti-HBc-negative/HBsAg-negative. Risk factors for atherosclerosis were collected based on medical records. Multiple logistic regression models were used to determine the association between infection patterns and ICAS. We found that the anti-HBc-positive / HBsAg-negative pattern was associated with the increased risk of ICAS (OR = 1.462) and not associated with ECAS or ICAS / ECAS. The HBc-positive/HBsAg-positive pattern was not associated with ICAS, ECAS or ICAS/ECAS. In conclusions, the anti-HBc-positive/HBsAg-negative pattern was associated with the increased risk of ICAS. Anti-HBc should be employed to investigate the association between HBV infection and cerebrovascular diseases.

Abstract
The prevalence of hepatitis B virus (HBV) infection was an imbalance in different provinces of China. This study aimed to investigate the prevalence of HBV infection and evaluate the prophylactic measures in a public hospital of northeast China over the preceding 13 years. A total of 13,948 patients in 2004 and 15,256 patients in 2017 of Shengjing Hospital of China Medical University were tested of serum HBsAg, HBeAg, HBsAb, HBeAb, and HBcAb levels with Abbott MEIA Kits. In people born before 1992, HBsAg-positive rate was 5.45% and 6.47%; isolated HBsAb positive rate was 14.62% and 21.24%; HBV marker negative rate was 54.27% and 42.77% in 2004 and 2017 survey, respectively. The males had a significant higher HBsAg-positive rate than the females. In people born during 1992-2004, HBsAg positive rate was 0.58% and 0.57%, isolated HBsAb positive rate was 41.47% and 46.57%; and HBV marker negative rate was 51.97% and 46.86% in 2004 and 2017 survey, respectively. Males and females had no difference of HBsAg-positive rate. In children born after 2005, HBsAg positive rate was 0.11%, isolated HBsAb positive rate was 76.68%, and HBV marker negative rate was 18.51% in 2017 survey. No difference of HBsAg-positive rate was found between the genders. A dramatic decrease of HBsAg positive rate and a progressive increase of HBsAb-positive rate were found among people born after 1992 and progressed further in those born after 2005. Immunization of infants and timely birth dose was the key method for prevention of HBV infection. Expanded HB vaccination would be needed for people born before 2005, especially those born between 1992 and 2004.

Abstract
PURPOSE This study developed and tested preliminary measurement properties of a Chinese scale specifically designed to measure HRQOL in patients with chronic hepatitis B (CHBQOL). METHODS We conducted 94 individual interviews with CHB patients to solicit items and five hepatitis expert interviews along with three rounds of cognitive interviews to identify problems with relevance and understanding of content. A cross-sectional validation study was then conducted to evaluate measurement properties (n = 578). Factor analysis was used to determine the latent structure of the scale. Reliability was evaluated through Cronbach's alpha coefficients and intra-class correlation coefficients (ICCs). Measurement model adequacy, convergent, discriminant, and known-groups validity were also examined. RESULTS A scale of 30 items was drafted. After item reduction, the remaining 23 items were assigned to the CHBQOL Somatic symptoms, Emotional symptoms, Belief and Social stigma domains, which had acceptable goodness of fit (χ2/df = 3.13, GFI = 0.90, AGFI = 0.88, RMSEA = 0.06, SRMR = 0.05). All the CHBQOL domains had satisfactory reliability with Cronbach's α coefficients ranging from 0.73 to 0.91 and ICCs were higher than 0.70 except for Belief domain (ICC = 0.54). Convergent and discriminant validity were acceptable as supported by significant item-domain correlations (0.64-0.90). In general, the correlations between CHBQOL and the SF-36 dimensions met hypotheses. Significant differences were found by mean scores in the subgroups of demographic and clinical variables, supporting the known-groups validity. CONCLUSIONS The CHBQOL instrument proved to be an appropriate tool for assessing HRQOL among Chinese CHB patients.

Increased risk of hepatitis B virus infection amongst individuals with diabetes mellitus. Biosci Rep 2019; 39:BSR20181715. [PMID: 30858308 PMCID: PMC6438870 DOI: 10.1042/bsr20181715] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 03/06/2019] [Accepted: 03/07/2019] [Indexed: 02/05/2023] Open
Abstract
There have been reports of hepatitis B outbreaks amongst diabetics in long-term care facilities, suggesting that risk of hepatitis B virus (HBV) infection is higher in this population. However, the magnitude of the risk and the incidence of HBV infection amongst the general diabetic population in China remains unknown. Data from a cohort study conducted in Mianyang City, Sichuan Province, China, were retrospectively analyzed in order to address this question. Demographic information was collected using a custom-designed questionnaire, and blood samples were tested for HBV using ELISA. We used multivariate logistic regression to explore the relationship between HBV infection and diabetes, while adjusting for age, sex, region, medical insurance, exposure history, and HBV vaccination. During 2013-2014, a total of 189766 adults were surveyed, of which 7382 were newly infected with HBV, corresponding to an incidence of 3.89%. In this study population, there were 4982 diabetic patients and 182710 non-diabetic individuals. Amongst those with diabetes, 265 (5.32%) were newly infected with HBV. In contrast, 7038 (3.85%) in the non-diabetic population were newly infected with HBV. The relative risk (RR) of HBV infection was 43% higher amongst those diagnosed with diabetes than amongst those not diagnosed (RR 1.43, 95% confidence interval (CI) 1.26-1.63). These results suggest that the risk of HBV infection is higher amongst individuals diagnosed with diabetes mellitus in Mianyang City, Sichuan Province, China. Hepatitis B vaccination and continuous infection control practices may help to reduce HBV infection in diabetic patients, and should be considered for diabetes management.

Abstract
BACKGROUND The aim of this study was to investigate the reactivation of the hepatitis B virus (HBV) following transarterial chemoembolization (TACE) in primary hepatocellular carcinoma (HCC) patients with HBV-DNA negative and to evaluate the effects of TACE combined with antiviral therapy. METHODS This prospective study involved 98 patients with HBV-related and HBV-DNA negative HCC (HBV DNA < 10 copies/mL) underwent TACE procedures with serial HBV DNA tests. Patients were divided into the antiviral treatment group and the no-antiviral group. The antiviral group received entecavir antiviral therapy, and the other group received no antiviral therapy. Two groups of patients were compared in rate of HBV reactivation and liver function before and after only 1 session of TACE in average 1-month follow-up after operation. P < .05 indicated differences with a statistical significance. RESULTS HBV reactivation occurred in 11 patients in the nonantiviral group (11/47, 23.4%) but only 3 patients in the antiviral group (3/51, 5.9%, P < .05). On multivariate analysis, HBeAg-positive status, number of tumors more than 3, and absence of antiviral therapy were the independent risk predictor of HBV reactivation. Liver function indicators did not differ significantly between the antiviral group and the nonantiviral group in 5 days after TACE. However, the level of alanine aminotransferase and bilirubin were raised and albumin was reduced at the HBV reactivation group compared with no HBV reactivation group (P < .05). At 1 month after TACE, liver function indicators did not differ significantly between the HBV reactivation group and without HBV reactivation group. CONCLUSION HCC patients with HBV DNA negative still remain associated with risk of HBV reactivation after TACE. HBeAg-positive, number of tumors more than 3, and absence of antiviral therapy in HCC patients after TACE have a higher risk of HBV reactivation. Antiviral therapy can reduce the risk of reactivation, helping improve liver function after TACE.

Abstract
Vaccination against hepatitis B virus (HBV) is recommended worldwide. The aim of this study was to assess the efficacy of infant hepatitis B vaccination and revaccination in 0- to 8-year-old children in the context of protective anti-HBs levels and cellular immune responses. Using a random questionnaire survey, 1695 pre-school children were recruited as research subjects during January 2015 to June 2017. Blood samples were obtained to measure HBV serological markers as well as peripheral immunocytes. The children were divided into non-, low- and hyper- responsive groups (NR, LR, and HR) based on the vaccination efficacy. Additionally, the effect of revaccination on the NR group was evaluated at 1 month after completion of the vaccination course. Among a total of 1695 children, 1591 (93.86%) were infants who were followed while undergoing their primary course of hepatitis B vaccination at the 0-1-6 month schedule, and 1249 (79.30%) of them developed antibodies against HBsAg (anti-HBs) titers greater than 10 IU/L. The results of immunocyte studies indicated that the CD8+ T cells, CD4+CD45RO+ T cells, CD8+CD45RA+ T cells, and T follicular helper (Tfh) cells increased significantly in NR compared with HR. However, lymphocytes, CD4+ T cells, and CD4+CD45RA+ T cells in NR were lower than that in HR. 96 of the non-response cases showed seroprotection after revaccination among 103 cases. Therefore, most of the preschool children who received hepatitis B vaccine in infancy achieved significant seroprotection. Seroconversion rates of individuals revaccinated after initial vaccination failure were significantly higher than those after primary vaccination. Different vaccination efficacy groups showed significant changes in circulating immunocytes, which might be a factor affecting the recombinant HBV vaccine's immune effectiveness.

Abstract
Hepatitis B (HB) vaccination is the most effective way to prevent HB virus infection. While measures taken to control the prevalence of HB have achieved significant results, HB prevalence in rural China among adults remains problematic. This study sheds new light on the determinants of HB vaccine uptake and its inequality according to socioeconomic status in rural areas of China. We interviewed 22,283 adults, aged 18-59 years, from 8444 households, in 48 villages from 8 provinces. Vaccination status was modeled by using two logistic models: whether take at least one HB vaccine and whether to complete the entire vaccination regime. The Erreygers' concentration index ([Formula: see text]) was used to quantify the degree of inequality and the decomposition approach was used to uncover the determinants of inequality in vaccine uptake. We found that the coverage rate of HB vaccination is 20.2%, and the completion rate is 16.0%. The [Formula: see text] of at least one dose (0.081) and three doses (0.076) revealed a substantial pro-rich inequality. Income contributed the largest percentage to HB vaccination inequalities (52.17% for at least one dose and 52.03% for complete vaccinations). HB awareness was another important cause of inequality in HB vaccination (around 30%). These results imply that rich had a greater tendency to vaccinate and inequality favouring the rich was almost equal for the complete three doses. While the factors associated with HB vaccination uptake and inequalities were multifaceted, income status and HB awareness were the main barriers for the poor to take HB vaccine by adults in rural China.

He H, Zhou Y, Xie S. Assessment of the duplicate notifiable reporting of hepatitis B infection in Zhejiang province, China, 2005-2015. Vaccine 2017; 35:4702-4706. [PMID: 28750855 DOI: 10.1016/j.vaccine.2017.07.039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2017] [Revised: 06/29/2017] [Accepted: 07/13/2017] [Indexed: 12/15/2022]
Abstract
BACKGROUND Hepatitis B virus (HBV) infection control has seen improvements since the introduction of the HBV vaccination program in China. However, the reported incidence rate of HBV infection remains high owing to the large pool of individuals infected before the start of the HBV immunization program. The duplicated reporting of HBV had a remarkable effect on the overestimation of HBV disease burden, according to the Chinese National Notifiable Diseases Report System (NNDRS). METHODS We analyzed the data of HBV in Zhejiang province, China, collected for the years 2005-2015 from the NNDRS. The duplicate reporting cases of HBV were captured according to the same identification number or the same name, sex and date of birth, or the same name, sex and resident town/street code. We assessed the magnitude of duplicated reporting of HBV and explored the possible factors contributing to duplicated reporting. RESULTS There were 20,078 redundant HBV cases reported from the NNDRS during 2005-2015, which accounted for 6.33% (19,272/305,654) of all patients owing to duplicate reporting in Zhejiang province, China. Some risk factors, including male sex, age ≥20years, chronic cases, residence in outside counties, and farming as an occupation (odds ratio [OR]=1.06; 95% confidence interval [CI]: 1.02-1.11) were positively associated with the risks on duplicate reporting. CONCLUSIONS Our results demonstrated that the duplicated reporting of HBV infection is common in Zhejiang, China, which has contributed to a higher HBV infection prevalence than its real value. Some characteristics might affect the probability of duplicate reporting, including sex, occupation, place of residence, HBV type, and hospital type. These findings indicated the strong need to improve the data collection, deletion of duplications, and HBV classification during HBV surveillance, in order to obtain an accurate estimate of HBV disease burden in China. We also suggest establishing a specialized system to achieve high-quality HBV infection surveillance effectively and practically.

Hepatitis B reactivation in occult viral carriers undergoing hematopoietic stem cell transplantation: A prospective study. Hepatology 2017; 65:1451-1461. [PMID: 28027590 DOI: 10.1002/hep.29022] [Citation(s) in RCA: 79] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2016] [Revised: 10/10/2016] [Accepted: 12/22/2016] [Indexed: 12/15/2022]
Abstract
UNLABELLED Hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg)-negative, antibody to hepatitis B core antigen (anti-HBc)-positive patients after allogeneic hematopoietic stem cell transplantation (HSCT) has not been prospectively studied. HBsAg-negative, anti-HBc-positive patients with undetectable HBV DNA undergoing allogeneic HSCT were prospectively monitored every 4 weeks. The primary endpoint was HBV reactivation, defined as detectable HBV DNA (≥10 IU/mL). Secondary endpoints included overall survival, HBsAg positivity, and changes in liver biochemistry and antibody to HBsAg levels. Among 297 allogeneic HSCT recipients, 85 (28.7%) were HBsAg-negative, anti-HBc-positive, of whom 62 were recruited and monitored for a median of 48 (4-104) weeks. The 2-year cumulative HBV DNA detectability rate was 40.8%, occurring at a median of 44 (8-100) weeks. Multivariate analysis showed that age ≥50 years (P = 0.004, hazard ratio = 8.2) and chronic graft-versus-host disease (P = 0.010, hazard ratio = 5.3) were significantly associated with HBV reactivation. Other clinical parameters, including baseline antibody to HBsAg status, serial changes in antibody to HBsAg levels, and donor serology, were not associated with HBV reactivation. Patients <50 years old and without chronic graft-versus-host disease, compared with the remaining patient cohort, had a significantly lower 2-year cumulative HBV reactivation rate (5.6% versus 65.0%, P = 0.004). Entecavir successfully suppressed HBV DNA to undetectable levels, with no cases developing biochemical hepatitis. CONCLUSION HBsAg-negative, anti-HBc-positive patients had a high rate of HBV reactivation after allogeneic HSCT, with determinants of HBV reactivation including age ≥50 years and chronic graft-versus-host disease; treatment strategies based on these parameters may prevent HBV reactivation and subsequent complications.

Abstract
The aim of study was to investigate the clinical features of treatment-naive patients in 2 regions with high- and intermediate-hepatitis B endemicity level in Southeast China and provide the baseline data for monitoring health or planning therapy.This study included 8207 cases of treatment-naive patients with hepatitis B virus (HBV) infection from Yuhuan (YH, high-hepatitis B endemicity region) and Shaoxing (SX, intermediate-hepatitis B endemicity region) during 2014-2015. Clinical data were collected from the patients. Blood samples were kept for detecting hepatitis B surface antigen, hepatitis B envelope antigen (HBeAg), hepatitis B envelope antibody, hepatitis B surface antibody, hepatitis B core antibody, liver function, HBV deoxyribonucleic acid, and alpha-fetoprotein. All persons underwent B ultrasound to exclude liver cirrhosis or cancer.Of all 8207 HBsAg-positive patients, 52.9% patients were in the low-replication (LR) stage and 30.3% in the HBeAg-negative chronic hepatitis B (ENH) stage; 8.8% cases were in the ENH stage with elevated alanine aminotransferase (ALT). More male than female patients were in immune clearance (IC) or ENH stages with elevated ALT (10.4% vs 4.8%, 12.1% vs 5.3%, respectively, P < .05). The percentage of patients in IC and immune tolerant (IT) stages declined with increasing age, whereas the percentages of ENH with elevated ALT stage were highest in 40 to 60 years.The percentage of patients in IT and IC stages was higher in YH than in SX (9.4% vs 3.8%, 9.9% vs 4.2%, respectively, P < .05). More patients had HBVDNA≥10 IU/mL in YH than in SX (24.6% vs 16.0%, P < .05), and more male than female patients had HBVDNA≥10 IU/mL(24.5% vs 17.9%, P < .05).Clinical features varied in treatment-naive patients with HBV infection between different genders and regions. More attention should be paid to the surveillance and therapy of patients in YH especially male patients for the prevention and prognosis of hepatitis B.

Prognosis of Intrahepatic Cholangiocarcinomas with HBV Infection is Better than Those with Hepatolithiasis After R0 Liver Resection: A Propensity Score Matching Analysis. Ann Surg Oncol 2017; 24:1579-1587.

Abstract
BACKGROUND The impact of different causative factors of intrahepatic cholangiocarcinoma (ICC) on disease outcome remains largely unknown. This study aimed to evaluate the prognosis of ICC patients with different pathogenic factors after hepatectomy. METHODS Data of 731 consecutive patients undergoing R0 liver resection for ICC at The Eastern Hepatobiliary Surgery Hospital between 2004 and 2010 were analyzed. These patients were divided into the hepatitis B virus-related (HBV-ICC, n = 519), hepatolithiasis-related (stone-ICC, n = 87), HBV plus hepatolithiasis-related (HBV/stone-ICC, n = 45), and other etiologies-related (other-ICC, n = 80) ICC groups. Propensity score matching (PSM) was used to eliminate the baseline differences between these groups. RESULTS In these four groups, the 5-year tumor recurrence and overall survival (OS) rates were 75.4, 90.3, 83.0 and 81.9%, and 32.7, 16.3, 17.7 and 22.6%, respectively. The significant differences in recurrence and OS were identified between the HBV- and stone-ICC groups (both p < 0.001). In these two groups, most of the independent prognostic predictors were similar, but tumor diameter >5 cm was demonstrated as a risk factor in the HBV-ICC patients only, and surgical margin <1 cm and human epidermal growth factor receptor 2-positive were demonstrated as risk factors in the stone-ICC patients only. With PSM, 75 patients in each of the HBV- and stone-ICC cohorts were created, and the 5-year recurrence and OS rates were 69.9 versus 88.6, and 34.6 versus 19.2%, respectively (p = 0.017, 0.027). CONCLUSION Patients with HBV-ICC achieved better outcomes than those with stone-ICC. This prognostic difference was probably associated with biological malignant invasiveness rather than tumor stage.

Abstract
INTRODUCTION Few studies have addressed the primary characteristics of patients infected with hepatitis B virus (HBV) in the general population, especially those living in small- and medium-sized cities in Brazil. We aimed to determine the clinical, demographic, and epidemiologic characteristics of patients diagnosed with HBV who were followed up at an infectious diseases clinic of a public hospital in State of São Paulo, Brazil. METHODS Medical records of patients aged >18 years and diagnosed with HBV infection between January 2000 and December 2013 were reviewed. RESULTS Seventy-five patients were enrolled with male-female main infection-associated risk factors; 9 (12%) were co-infected with human immunodeficiency virus (HIV), 5 (6.7%) with hepatitis C virus (HCV), and 3 (4%) were co-infected with both HIV and HCV. Antiviral HBV therapy was applied in 21 (28%) patients and tenofovir monotherapy was the most prescribed medication. After approximately 2 years of antiviral treatment, the HBV-DNA viral load was undetectable in 12 (92.3%) patients and lower levels of alanine aminotransferase were found in these patients. CONCLUSIONS Over a 13-year interval, very few individuals infected with HBV were identified, highlighting the barriers for caring for patients with HBV in developing countries. New measures need to be implemented to complement curative practices.

[PMID: 27644733 DOI: 10.1038/ajg.2016.436] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2016] [Accepted: 08/15/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Hepatitis B core-related antigen (HBcrAg) is a novel serum marker that correlates with intrahepatic hepatitis B virus (HBV) activity. Its association with HBV reactivation in hepatitis B surface antigen (HBsAg)-negative antibody to hepatitis B core antigen (anti-HBc)-positive patients undergoing high-risk immunosuppressive therapy is undefined. METHODS HBcrAg was measured in HBsAg-negative, anti-HBc-positive Asian patients with undetectable HBV DNA, who participated in two prospective studies investigating HBV reactivation during rituximab-containing chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT). Patients were monitored every 4 weeks for up to 2 years, with entecavir started when HBV reactivation, defined as HBV DNA ≥10 IU ml-1, developed. RESULTS One hundred and twenty-four HBsAg-negative, anti-HBc-positive patients (rituximab, N=62; allogeneic HSCT, N=62) with a median follow-up of 64 weeks (range: 4-104 weeks) were studied. HBV reactivation occurred in 31 patients, with a 2-year cumulative reactivation rate of 40.4%. Serum HBcrAg was detected in 43 (34.7%) patients. Baseline HBcrAg positivity was significantly associated with HBV reactivation (P=0.004, hazard ratio (HR): 2.94, 95% confidence interval (95% CI): 1.43-6.07). HBcrAg-positive patients had a significantly higher 2-year HBV reactivation rate than HBcrAg-negative patients (71.8 vs. 31%, P=0.002). In the rituximab cohort, the HRs for positive HBcrAg and negative antibody to HBsAg for HBV reactivation were 3.65 and 2.84, respectively (P=0.011, 95% CI: 1.35-9.86 and P=0.032, 95% CI: 1.10-7.37, respectively). CONCLUSIONS Serum HBcrAg positivity is a significant risk factor of HBV reactivation in HBsAg-negative, anti-HBc-positive patients undergoing high-risk immunosuppressive therapy and can potentially have a role in identifying patients who will best benefit from prophylactic nucleoside analogue treatment.

Cost-effectiveness analysis of hepatocellular carcinoma screening by combinations of ultrasound and alpha-fetoprotein among Alaska Native people, 1983-2012. Int J Circumpolar Health 2016; 75:31115. [PMID: 27197711 PMCID: PMC4873562 DOI: 10.3402/ijch.v75.31115] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2015] [Revised: 04/25/2016] [Accepted: 05/02/2016] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND The American Association for the Study of Liver Diseases (AASLD) recommends semi-annual hepatocellular carcinoma (HCC) screening using ultrasound (US) in persons with chronic hepatitis B (CHB) virus infection at high risk for HCC such as Asian males aged ≥40 years and Asian females aged ≥50 years. OBJECTIVE To analyse the cost-effectiveness of 2 HCC screening methods in the Alaska Native (AN) health system: US-alone, or screening by alpha-fetoprotein (AFP) initially and switching to US for subsequent screenings if AFP >10 ng/mL (AFP→US). DESIGN A spreadsheet-based model was developed for accounting the costs of 2 hypothetical HCC screening methods. We used epidemiologic data from a cohort of 839 AN persons with CHB who were offered HCC screening by AFP/US semi-annually during 1983-2012. We assumed that compared with AFP→US, US-alone identifies 33% more tumours at an early stage (defined as a single tumour ≤5 cm or ≤3 tumours ≤3 cm in diameter). Years of life gained (YLG) attributed to screening was estimated by comparing additional years of survival among persons with early- compared with late-stage tumours. Screening costs were calculated using Medicare reimbursement rates in 2012. Future screening costs and YLG were projected over a 30-year time horizon using a 3% discount rate. RESULTS The total cost of screening for the cohort by AFP→US would have been approximately $357,000 ($36,000/early-stage tumour detected) compared to $814,000 ($59,000/early-stage tumour detected) by US-alone. The AFP→US method would have yielded an additional 27.8 YLG ($13,000/YLG) compared with 38.9 YLG ($21,000/YLG) for US-alone. Screening by US-alone would incur an additional $114,000 per extra early-tumour detected compared with AFP→US and $41,000 per extra YLG. CONCLUSIONS Although US-alone HCC screening might have yielded more YLG than AFP→US, the reduced costs of the AFP→US method could expand access to HCC screening in resource constrained settings.

A comparison of lamivudine vs entecavir for prophylaxis of hepatitis B virus reactivation in allogeneic hematopoietic stem cell transplantation recipients: a single-institutional experience. Bone Marrow Transplant 2016; 51:581-6. [PMID: 26752138 DOI: 10.1038/bmt.2015.328] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2015] [Revised: 11/22/2015] [Accepted: 11/23/2015] [Indexed: 01/04/2023]
Abstract
The aim of this study was to compare the efficacy of lamivudine vs entecavir in the prevention of hepatitis B virus (HBV) reactivation in HBV surface Ag (HBsAg)-positive patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 216 consecutive patients were enrolled and retrospectively reviewed. Of these patients, 119 received lamivudine and 97 received entecavir. The median treatment duration to complete virological response in patients with baseline HBV-DNA levels >10(5) copies/mL was 2.0 months in the entecavir group, significantly shorter than that of the lamivudine group. After a median follow-up of 24 months post transplantation, the cumulative incidence rates of HBV reactivation at 6, 12 and 24 months following transplantation were 3.0%, 7.0% and 24.0% in the lamivudine group, and 0%, 0% and 2.0% in the entecavir group, respectively. In addition, entecavir treatment was associated with lower cumulative incidence rates of severe hepatitis caused by HBV reactivation. Mutations leading to drug resistance were detected in 25 patients in the lamivudine group and in only one patient in the entecavir group. Our data indicate that compared with lamivudine, entecavir has more potent antiviral efficacy and may be a better choice for prophylaxis of HBV reactivation in HBsAg-positive allo-HSCT recipients.

Sustained high prevalence of viral hepatitis and sexually transmissible infections among female sex workers in China: a systematic review and meta-analysis. BMC Infect Dis 2016; 16:2. [PMID: 26732281 PMCID: PMC4702370 DOI: 10.1186/s12879-015-1322-0] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2015] [Accepted: 12/12/2015] [Indexed: 02/06/2023] Open
Abstract
Background The 1980’s economic boom has been associated with a rapid expansion of China’s sex industry over the past three decades. Consequently, the spread of sexually transmitted infections (STIs) and hepatitis infections among female sex workers (FSW) has become an important public health issue in China. This study identifies prevalence and risks of hepatitis and STIs in Chinese FSWs. Method Four electronic databases were searched for Chinese and English language peer-reviewed studies conducted between 01/2000-12/2011 that reported prevalence of hepatitis and STIs (excluding HIV) among Chinese FSW. Following the PRISMA guidelines, meta-analysis was used to estimate pooled prevalence and 95 % confidence intervals for each infection. Result Three hundred and thirty nine articles (34 in English and 305 in Chinese) investigating 603,647 FSWs in 29 Chinese provinces were included in this review. Over the period 2000–2011, the seroprevalence of active hepatitis B and hepatitis C among FSW were 10.7 % (7.3–15.5 %) and 1.0 % (0.7–1.3 %), respectively. The most prevalent STI was human papillomavirus (HPV, 27.0 % [10.1–55.1 %]), followed by herpes simplex virus-2 (HSV-2, 15.8 % [11.7–20.9 %]), chlamydia (13.7 % [12.1–15.4 %]), gonorrhoea (6.1 % [5.3–7.0 %]), syphilis (5.2 % [4.8–5.7 %]), genital warts (3.3 % [2.5–4.2 %]) and Trichomonas vaginitis (2.1 % [1.5–24.2 %]). Disease burden of both hepatitis and STI among FSW were concentrated in South Central and Southwest China. In particular, chlamydia and syphilis demonstrated a significant declining trend during the studied period (P < 0.05). Compared with the general Chinese population, FSW had significantly higher prevalence of all STIs except Trichomonas vaginitis. Further, compared to the general FSW population, HIV-positive FSW had significantly higher prevalence of syphilis, chlamydia, HSV-2 and Trichomonas vaginitis. Conclusion Prevalence of hepatitis and STIs remained high and mostly stable among Chinese FSW over the period of 2000–2011. Targeted STI and hepatitis surveillance and interventions should be strengthened among Chinese FSWs, especially those who are HIV-positive.

Seroepidemiology of hepatitis B virus infection in 2 million men aged 21-49 years in rural China: a population-based, cross-sectional study. THE LANCET. INFECTIOUS DISEASES 2016; 16:80-86. [PMID: 26268687 DOI: 10.1016/s1473-3099(15)00218-2] [Citation(s) in RCA: 155] [Impact Index Per Article: 17.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2015] [Revised: 07/03/2015] [Accepted: 07/10/2015] [Indexed: 12/25/2022]
Abstract
BACKGROUND Hepatitis B virus (HBV) infection is highly endemic (7-8% prevalence) in rural China, causing high mortality and societal burden. Data from men of reproductive age is scarce and last reported in 2006. We assessed the seroepidemiology of men in rural China, aiming to provide updated baseline data for the prevalence of HBV infection. METHODS We established prevalence of HBV infection from data gathered through a nationwide population-based study of Chinese rural men aged 21-49 years. Data were obtained from a physical check-up programme for couples of reproductive age, the National Free Preconception Health Examination Project, that covered 31 provinces from 2010-12. We tested serological samples with ELISA and categorised participants' HBV status based on presence of HBsAg, anti-HBV core antibody (anti-HBc), and anti-HBV surface antibody (anti-HBs). FINDINGS 2 030 083 men were recruited into the database from Jan 1, 2010, to Dec 31, 2012, and 1 966 013 men provided serum samples for analysis. 124 274 men (6%) tested positive for HBsAg, 178 559 (9%) tested positive for anti-HBc, and 583 923 (30%) tested positive for anti-HBs. Isolated anti-HBs (an indicator of vaccine-mediated immunity) were present in 527 566 men (27%). And 1 234 127 men (63%) were negative for all HBV makers (susceptible population). HBsAg prevalence was higher in men aged 25-39 years (6·35-6·47%) than in other age groups (5·54-5·78%; p<0·0001). HBV markers were all more prevalent in the eastern region of China than in the central or western regions (all p<0·0001). 32 326 (26%) of 124 274 HBsAg-positive men tested positive for HBeAg (suggesting high infectiousness); this decreased with increasing age (p<0·0001). INTERPRETATION HBV prevalence in men in rural China has changed from highly endemic into intermediate endemic in the past two decades. However, the absolute number of HBV-infected men and the susceptible population is still very large. FUNDING Chinese Association of Maternal and Child Health Studies.

Abstract
AIM To investigate hepatitis B virus (HBV) prevalence in the general population in China. METHODS A total of 148931 individuals were investigated by multistage random sampling in Eastern China. Data were collected on demographics and hepatitis B vaccination history, and serum was tested for hepatitis B surface antigen (HBsAg) by ELISA. RESULTS A total of 11469 participants (7.70%, 95%CI: 7.57%-7.84%) were positive for HBsAg. HBsAg prevalence was 0.77% among children < 5 years old but increased progressively from adolescents (1.40%-2.55%) to adults (5.69%-11.22%). A decrease in HBsAg prevalence was strongly associated with vaccination and familial history of HBV among both children and adult groups. Meanwhile, HBsAg risk in adults was associated with invasive testing and sharing needles. The HBV immunization rate among participants aged < 20 years was 93.30% (95%CI: 93.01%-93.58%). Significant difference in HBsAg prevalence appeared between vaccinated and unvaccinated participants (3.59% vs 10.22%). CONCLUSION Although the national goal of HBsAg prevalence < 1% among children < 5 years old has been reached, immunization programs should be maintained to prevent resurgence.

Abstract
This study was aimed to evaluate the long-term effects of telbivudine (LdT) in the treatment of chronic hepatitis B (CHB) and HBV-related liver cirrhosis (LC) and to observe the changes of immunological responses during LdT treatment. Clinical data of 80 CHB and 28 HBV-related LC patients who were administered with LdT for 108 weeks and followed up were retrospectively analyzed. The liver function indicators including ALT, AST and γ-GT, HBV DNA copy number in serum and the rates of hepatitis B e antigen (HBeAg) seroconversion were analyzed before and 12, 24, 36, 48, 60, 72, 84, 96 and 108 weeks after LdT treatment in CHB and LC groups. Four serum fibrosis-related markers, including hyaluronic acid (HA), human laminin (LN), human type IV collagen (IV-C) and human N-terminal procollagen III peptide (PC-III), were detected before and after LdT treatment in LC group. The results showed favorable viral suppression and biochemical responses after treatment with LdT for 12 weeks, and a high rate of virological and biochemical control was maintained during the course of 108-week treatment in both CHB and LC groups. The four fibrosis-related markers, especially HA and LN, were down-regulated to some degrees in LC group. Moreover, LdT treatment led to the fluctuation of the circulating interferon-γ (IFN-γ) and interleukin-10 (IL-10) levels at different time points in CHB group. It was concluded that LdT could favorably lead to the virological suppression and biochemical remission. Besides, IFN-γ and IL-10 may represent a suitable and effective predictor of responsiveness during LdT therapy.

Abstract
Zhejiang Province was a high endemicity for hepatitis B disease in the 1990's. A number of measures implemented since then have begun to control and prevent hepatitis B. In 1992, hepatitis B vaccine came on the market. In 2002, hepatitis B vaccine was included in the national Expanded Programme on Immunization (EPI). Between 2007 and 2010, catch-up vaccination was implemented for children under 15. Since 2010, vaccination guidelines for high-risk groups have also been adopted. This study evaluated the impact of these control and prevention strategies on acute hepatitis B notification rates from 2005 through 2013. Data from the National Notifiable Disease Reporting System (NNDRS) revealed a steady downward trend in notification rates of acute hepatitis B. The most dramatic decline occurred among pre-adults, highlighting the benefits of EPI's policy of universal vaccination for children. However, the highest notification rates occurred among young adults of lower socio-economic status. These findings indicate the strong need to vaccinate young adults at risk for HBV infection as well as to collect risk-factor information in the NNDRS for monitoring and following up persons with acute hepatitis B.

Abstract
PURPOSE Patterns of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) -negative, antihepatitis B core antigen antibody (anti-HBc) -positive patients with lymphoma receiving rituximab-containing chemotherapy have not been well described. PATIENTS AND METHODS HBsAg-negative, anti-HBc-positive Chinese patients with undetectable serum HBV DNA (< 10 IU/mL), diagnosed with hematologic malignancies and receiving rituximab-containing chemotherapy, were prospectively monitored every 4 weeks for up to 2 years. Entecavir was started when HBV reactivation (defined as detectable HBV DNA) was encountered. RESULTS Among 260 patients receiving rituximab-containing chemotherapy, 63 patients (24.2%) who were HBsAg negative and anti-HBc positive underwent follow-up for a median of 70 weeks (range, 6 to 104 weeks). The 2-year cumulative rate of HBV reactivation was 41.5%, occurring at a median of 23 weeks (range, 4 to 100 weeks) after rituximab treatment. The median HBV DNA level at reactivation was 43 IU/mL (range, 14 to 920 IU/mL). A baseline undetectable antibody to HBsAg (anti-HBs; < 10 mIU/mL) was the only significant risk factor that was positively associated with HBV reactivation (hazard ratio, 3.51; 95% CI, 1.37 to 8.98; P = .009). Patients with negative baseline anti-HBs, compared with those with positive anti-HBs, had a significantly higher 2-year cumulative rate of HBV reactivation (68.3% v 34.4%; P = .012). At HBV reactivation, all patients had normal ALT, and all patients but one were HBsAg negative. Entecavir successfully controlled HBV reactivation in all patients. CONCLUSION A high rate of HBV reactivation was observed in HBsAg-negative, anti-HBc-positive patients undergoing rituximab-containing chemotherapy, with the risk of reactivation significantly higher in anti-HBs-negative patients. Periodic HBV DNA monitoring was an effective strategy in preventing HBV-related complications.

Cancer Sci 2014; 105:697-703. [PMID: 24654677 PMCID: PMC4317906 DOI: 10.1111/cas.12400] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2014] [Revised: 03/10/2014] [Accepted: 03/16/2014] [Indexed: 12/20/2022] Open
Abstract
This study investigated whether conformal radiotherapy affects hepatitis B virus (HBV) reactivation, and the risk factors for HBV reactivation in patients with HBV-related hepatocellular carcinoma (HCC). Sixty-nine patients with HCC were included in this retrospective study. Before radiotherapy (RT), all patients underwent imaging examinations and some baseline examinations, including CBC, liver function test, renal function test, α-fetoprotein level, hepatitis B (HB) surface antigen, HB surface Ab, HB e antigen, HB e Ab, and serum HBV DNA quantification. During the period of RT and at least 16 weeks after the end of RT, CBCs were carried out weekly and the other tests were monitored monthly or more frequently if necessary. The clinical features and dosimetric parameters of RT were recorded. Univariate and multivariate logistic regression algorithms were used to analyze the risk factors of HBV reactivation. The incidence of complications in the study population was as follows: radiation-induced liver disease, 17.4%; HBV reactivation, 24.6%; and HBV reactivation-induced hepatitis, 21.7%. The HBV DNA level and dose volume parameters including normal liver volume, V20, and mean dose were associated with HBV reactivation. There was a relatively high incidence of HBV reactivation in HCC patients after the end of conformal RT. The serum HBV DNA level and some dosimetric parameters related to normal liver, including normal liver volume, V20, and mean dose, were the prognosis factors of HBV reactivation and should be carefully considered before conformal RT.

Abstract
Background Sexually transmitted infections (STIs), including Hepatitis B and C virus, are emerging public health risks in China, especially among men who have sex with men (MSM). This study aims to assess the magnitude and risks of STIs among Chinese MSM. Methods Chinese and English peer-reviewed articles were searched in five electronic databases from January 2000 to February 2013. Pooled prevalence estimates for each STI infection were calculated using meta-analysis. Infection risks of STIs in MSM, HIV-positive MSM and male sex workers (MSW) were obtained. This review followed the PRISMA guidelines and was registered in PROSPERO. Results Eighty-eight articles (11 in English and 77 in Chinese) investigating 35,203 MSM in 28 provinces were included in this review. The prevalence levels of STIs among MSM were 6.3% (95% CI: 3.5–11.0%) for chlamydia, 1.5% (0.7–2.9%) for genital wart, 1.9% (1.3–2.7%) for gonorrhoea, 8.9% (7.8–10.2%) for hepatitis B (HBV), 1.2% (1.0–1.6%) for hepatitis C (HCV), 66.3% (57.4–74.1%) for human papillomavirus (HPV), 10.6% (6.2–17.6%) for herpes simplex virus (HSV-2) and 4.3% (3.2–5.8%) for Ureaplasma urealyticum. HIV-positive MSM have consistently higher odds of all these infections than the broader MSM population. As a subgroup of MSM, MSW were 2.5 (1.4–4.7), 5.7 (2.7–12.3), and 2.2 (1.4–3.7) times more likely to be infected with chlamydia, gonorrhoea and HCV than the broader MSM population, respectively. Conclusion Prevalence levels of STIs among MSW were significantly higher than the broader MSM population. Co-infection of HIV and STIs were prevalent among Chinese MSM. Integration of HIV and STIs healthcare and surveillance systems is essential in providing effective HIV/STIs preventive measures and treatments. Trial Registration PROSPERO No: CRD42013003721

Abstract
BACKGROUND Red blood cell distribution width (RDW) is increased in liver disease. Its clinical significance, however, remains largely unknown. The aim of this study was to identify whether RDW was a prognostic index for liver disease. METHODS We studied, retrospectively, 33 patients with non-cirrhotic HBV chronic hepatitis, 125 patients with liver cirrhosis after HBV infection, 81 newly diagnosed primary hepatocellular carcinoma (pHCC) patients, 17 alcoholic liver cirrhosis patients and 42 patients with primary biliary cirrhosis (PBC). Sixty-six healthy individuals represented the control cohort. We analyzed the relationship between RDW on admission and clinical features. The association between RDW and hospitalization outcome was estimated by receiver operating curve (ROC) analysis and a multivariable logistic regression model. RESULTS Increased RDW was observed in liver disease patients. RDW was positively correlated with serum bilirubin and creatinine levels, prothrombin time, and negatively correlated with platelet counts and serum albumin concentration. A subgroup analysis, considering the different etiologies, revealed similar findings. Among the patients with liver cirrhosis, RDW increased with worsening of Child-Pugh grade. In patients with PBC, RDW positively correlated with Mayo risk score. Increased RDW was associated with worse hospital outcome, as shown by the AUC [95% confidence interval (CI)] of 0.76 (0.67-0.84). RDW above 15.15% was independently associated with poor hospital outcome after adjustment for serum bilirubin, platelet count, prothrombin time, albumin and age, with the odds ratio (95% CI) of 13.29 (1.67-105.68). CONCLUSIONS RDW is a potential prognostic index for liver disease.

Abstract
Background Hepatitis B virus (HBV) infection is a significant global health problem, especially in China. Chronic liver disease affects health related quality of life (HRQOL). The intervention method to improve HRQOL in patients with hepatitis B has been one-dimensional with inconsistent results. The purpose of this study was to evaluate the effect of comprehensive intervention on health-related quality of life and provide guidance on improving HRQOL for patients with chronic hepatitis B. Methods Patients with chronic hepatitis B eligible for our study were randomly selected in three model regions of Jiangsu Province in June 2010. 272 patients were invited and 254 took part, with a refusal rate of 6.62%. Comprehensive intervention included government support, technical guidance from the Chinese Centre for Disease Control and Prevention, standardised medical care, and community involvement. HRQOL before and 1 year after intervention was measured with the Short Form 36 and HBV-specific health surveys. Chi-square test, t-test and multiple linear regressive analyses were used. Results After comprehensive intervention, the HRQOL in patients with chronic hepatitis B showed significantly improvements in bodily pain, vitality, social functioning, and mental, as well as physical and mental component score (p < 0.05). Family and social support increased, and financial concerns decreased (p < 0.05). Marital status, duration of illness-related absence from work, education level, family financial status, and health insurance type were important factors affecting HRQOL change between the baseline and final assessment in patients with chronic hepatitis B. Conclusion The comprehensive intervention was effective in improving the HRQOL of patients with chronic hepatitis B. Trial registration ChiCTR-OCH-12001882

Abstract
BACKGROUND Selective pressure from either the immune response or the use of nucleoside analogs in antiviral therapy could be driving the emergence of HBV mutants. Because of the overlap of the open reading frame (ORF) S for the HBsAg and ORF P for viral polymerase, rtM204I and rtM204V mutations in the polymerase would produce sI195M and sW196S in the HBsAg. The combined effects of immune-escaped mutations (sT118M, sG145K, sG145R) and drug-resistant mutations (rtM204I, rtM204V) on the antigenicity profiles of HBsAg has not been widely explored. METHODS To determine the combined effects of immune-escaped and drug-resistant mutants on the antigenicity profiles of HBsAg, recombinant plasmids encoding HBsAg double mutants were constructed using site-directed mutagenesis. The supernatant from each plasmid transfection was analyzed for HBsAg in the western-blotting and five of the most commonly used commercial ELISA kits in China. RESULTS Western-blotting assay showed the successful expression of each HBsAg mutant. All five ELISA kits manifested similar avidity, which were demonstrated by the slope of the curves, for the sT118M mutant, and sT118M-rtM204I (sT118M-sI195M) and sT118M-rtM204V (sT118M-sW196S) double mutants, suggesting that drug-resistant YMDD mutants caused negligible losses in the antigenicity of immune-escaped sT118M HBsAg. In contrast, the presence of the rtM204I (sI195M) mutation, but not rtM204V (sW196S) in combination with the sG145K mutation significantly reduced the avidity of sG145K HBsAg. The rtM204I (sI195M) mutation also decreased the antigenicity profiles for sG145R HBsAg. CONCLUSIONS Drug-resistant mutations rtM204I (sI195M) and rtM204V (sW196S) caused significant reduction in antigenicity for the immune-escaped HBsAg mutants sG145K and sG145R, which may hamper HBV diagnosis and disease control from HBV blood-transfusion transmissions in China. The development of ELISA kits with a greater sensitivity for drug-resistant and immune-escaped HBsAg warrants further consideration.

Abstract
Objective Hepatitis B virus (HBV) infection remains a significant public health problem. The purpose of this study was to investigate the seroepidemiology of HBV in people living in the insular regions, and to provide the most recent baseline data for planning and monitoring of health. Methods A cross-sectional, community-based survey was conducted without age restriction, on two isolated islands, Zhoushan and Yuhuan, China. The study sample was selected by random multistage cluster sampling. Serological samples and demographic information were collected from 15878 participants. Results The prevalences of anti-HBV core antibody (anti-HBc), hepatitis B virus surface antigen (HBsAg), and anti-HBV surface antibody (anti-HBs) were 33.1, 10.4, and 56.1%, respectively. We found statistically significant differences of HBV markers in men versus women (P<0.01). The prevalence of HBV infection increased with age. There were significant differences in the rates of HBsAg and anti-HBc positivity between the two islands (P<0.01). Alanine aminotransferase (ALT) levels were elevated (>38 IU/L) in 15.6% and 7.2% of the HBsAg-positive and negative groups, respectively. Elevated ALT levels were significantly higher in males (12.0%) compared with females (5.8%) (P<0.01). The α-fetoprotein (AFP) positivity rate was 0.6% in HBsAg-positive participants over the age of 30. Conclusion Due to the geographic location, we found that the HBV prevalence and potential for the development of hepatocellular carcinoma remained high in insular regions of southeast China, and are far above the national figures. Although a vaccination program has been in effect over the last 20 years, several additional measures should be adopted by the government to limit the spread of hepatitis B. These include the management of high risk persons and the floating population living on the islands, expansion of the immune population, and increased health education for fisherman.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection has remained a significant public health problem. Generating a large-scale, community-based profile of HBV infection in China is essential to prevention of the disease. OBJECTIVES The current study was designed to investigate HBV-infected individuals at the community level and determine the age distribution, hepatitis B e antigen (HBeAg) positivity and its related risk factors, relationship among serological markers. PATIENTS AND METHODS A cross-sectional, community-based survey was carried out without age restriction, in 12 communities of two counties. The study population was selected by random multistage cluster sampling. Serological samples and demographic information were collected from 8439 HB surface antigen (HBsAg)-positive individuals. RESULTS The constituent ratio of individuals with HBsAg-positive infections was lowest among persons aged < 20 years (0.4%) and the highest among persons aged 40-49 years (33.2%). The HBeAg-positive rate among infected individuals was 18.5%, and the constituent ratio decreased with increasing of age. The HBeAg-positive rate in males (21.9%) was significantly higher than in females (14.7%), and was higher among coastland inhabitants (22.9%) than among plains inhabitants (12.9%). Among the 1561 HBeAg-positive individuals, 91.0% were HBV DNA-positive. However, of the 6878 HBeAg-negative individuals, only 45.4% were HBV DNA-positive, and the HBeAg-positive rate was significantly different at different levels of HBV DNA expression. The proportion of detectable HBV DNA levels was significantly higher in individuals with elevated ALT, compared to those with normal ALT, regardless of HBeAg-positivity. CONCLUSIONS The HBV prevalence remained high in the > 20 age group. The positivity of HBeAg was related to age, region, and sex. Testing HBeAg and serum ALT levels were effective ways to assess HBV infectiousness in community-level hospitals in China.

Abstract
Lamivudine (LAM) resistance now poses a major problem in the management of patients with chronic hepatitis B virus (HBV) infection. We retrospectively collected clinical data on chronic HBV-infected patients who had developed LAM resistance under de novo LAM monotherapy and subsequently took nucleos(t)ide analogs as rescue strategy in our hospital. From initiation of rescue therapies to January 2012, incidence of antiviral drug resistance was 23.67%, 18%, 6.94% and 0% (P=0.007) in the group of switching to adefovir dipivoxil (ADV) monotherapy, switching to entecavir (ETV) monotherapy, adding on ADV and switching to combination of ADV and ETV. At month 12, the median levels of serum HBV DNA were respectively 9300IU/mL, 4648IU/mL, 2054IU/mL and 100IU/mL (P<0.001), and the cumulative rates of serum ALT normalization were respectively 75%, 84%, 93% and 100% (P=0.003). Additionally, the strategy of switching to ADV monotherapy induced more single rtA181T mutations. In conclusion, switching to ADV monotherapy has been widely used in real-world clinical practice in China, however, due to the high incidence of drug resistance, switching to neither ADV nor ETV monotherapy is optimal when LAM resistance occurs; combination of ADV and ETV is most effective, whereas the strategy of adding on ADV is rational for most of LAM-resistant Chinese patients with chronic hepatitis B.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection is a major cause of morbidity and mortality worldwide. Chronic hepatitis B infection is associated with an increased risk of cirrhosis, hepatic decompensation, and hepatocellular carcinoma. Our aim is to analyze, through a mathematical model, the potential impact of anti-HBV vaccine in the long-term (that is, decades after vaccination) number of LT. METHODS The model simulated that the prevalence of HBV infection was 0.5% and that approximately 20% of all the liver transplantation carried out in the state of São Paulo are due to HBV infection. RESULTS The theoretical model suggests that a vaccination program that would cover 80% of the target population would reach a maximum of about 14% reduction in the LT program. CONCLUSION Increasing the vaccination coverage against HBV in the state of São Paulo would have a relatively low impact on the number of liver transplantation. In addition, this impact would take several decades to materialize due to the long incubation period of liver failure due to HBV.

Abstract
OBJECTIVE To evaluate the influence of hepatitis B virus (HBV) coinfection on immunological, virological and clinical responses to lamivudine (3TC)-based combined antiretroviral therapy (cART) in Chinese patients. DESIGN AND METHODS This prospective, multicenter cohort study recruited 529 antiretroviral-naive participants (aged 18–65 years, both sexes) between 2008 and 2010.They were grouped by HBV serostatus. Virological and immunological responses were monitored at baseline and week 4, 8, 12, 24, 36 and 48. cART for all patients was nevirapine, 3TC with either zidovudine or stavudine. RESULTS First, HIV/HBV coinfection rate in our cohort was 14.6%. Second, among 508 patients with complete baseline information, median CD4 level was significantly lower in the chronic HBV-infected (CHB) group and isolated core group. In the CHB group,hepatitis B e antigen positivity rather than HBV DNA level was associated with lower CD4 cell count. Third, in the isolated core group, occult infection rate was 9.5%.Fourth, at week 48, rate of HIV suppression below 40 copies/ml was 74.2%. Median increase in the CD4 cell count at week 48 was 127 cells/ml. Of note, HBV serostatus did not influence virological and immunological response to cART at each follow-up time point. Although HBV serostatus was associated with different alanine aminotransferase levels during follow-up, hepatitis and hyperbilirubinemia rates were not significantly different. Fifth, the 3TC-based regimen was efficacious against HBV replication, with median decrease in HBV DNA of 2.87 log copies/ml. However, hepatitis B e antigen positivity was associated with poorer HBV DNA suppression. CONCLUSION In our cohort, CHB infection and isolated hepatitis B core antibody positivity were related to faster HIV progression. Despite of this, virological and immunological responses were not affected by HBV serostatus.

Abstract
The present study was aimed to obtain baseline information of basal core promoter A1762T/G1764A and precore G1896A mutations of hepatitis B virus (HBV) in 192 HBeAg-positive chronically-infected Chinese patients, who were potential candidates for antiviral treatment. The detection of these mutations (including minor mutant subpopulations) was achieved by direct sequencing, whose sensitivity for minor mutant subpopulations identification was confirmed by clone sequencing. Patients enrolled were infected with either genotype B (46.35%) or C (53.65%) HBV identified by routine tests in our laboratory. The A1762T/G1764A or G1896A mutations were detected in 125specimens (125/192, 65.10%), in which 77 (77/125, 61.60%) existed as subpopulations. The A1762T/G1764A mutations were found to be more prevalent in genotype C than that in genotype B HBV [62.14% (64/103) vs. 20.22% (18/89), P<0.0001]. There is no statistically significant link between G1896A and genotypes. The emergence of A1762T/G1764A mutations was also found to be associated with an older age, an elevated ALT/AST level, and a lower HBsAg level in serum [wild-type vs. mutant: 4.57 (3.46-5.42) vs. 3.93 (2.51-5.36), P<0.0001]. In conclusion, HBV basal core promoter mutations A1762T/G1764A are associated with genotype C and a low serum HBsAg level in chronically-infected HBeAg-positive Chinese patients.

Abstract
The Chinese national goals for control of hepatitis B virus (HBV) infection were to achieve a prevalence of HBsAg below 7% for the entire population, and 1% for children under 5-year old, by 2010. To determine whether Guangxi, a multi-minority province with a low socio-economic status and a very high prevalence of HBV, achieved this goal, a seroepidemiological survey of HBV infection was carried out using stratified, random cluster sampling. The results show that the overall prevalence of HBsAg is 9.16% [95% confidence interval (CI) = 8.32-10%]. The prevalence in males (10.96%, 95% CI = 9.64-12.28%) is significantly higher than in females (7.71%, 95% CI = 6.64-8.78%; χ(2) = 10.5923, P < 0.05). The prevalence in children under 5-year old is 3.62% (95% CI = 0.60-6.64%) and increases with age. The prevalence of HBsAg in non-immunized individuals is significantly higher than in those immunized completely, although not within 24 hr of birth (χ(2) = 31.426, P < 0.05); a significant difference was found in those below the age of 20 years but not in older persons. Gender, age, immunization history, and familial HBsAg carriers are risk factors for infection. In conclusion, this study indicates that Guangxi has not reached the goal for the control of HBV infection. Catch-up HBV immunization may not protect adults effectively against infection in highly endemic regions.

Abstract
Background Hepatitis B virus (HBV) is still one of the serious infectious risks for the blood transfusion safety in China. One plausible reason is the emergence of the variants in the major antigenic alpha determinant within the major hydrophilic region (MHR) of hepatitis B surface antigen (HBsAg), which have been assumed to evade the immune surveillance and pose a challenge to the disease diagnosis. It is well documented that some commercial ELISA kits could detect the wild-type but not the mutant viruses. The high prevalence of HBV in China also impaired the application of nucleic acid testing (NAT) in the improvement of blood security. Molecular epidemiological study of HBsAg variations in China is still limited. This study was designed to identify the prevalence of mutations in the HBsAg in voluntary blood donors in Nanjing, China. Methods A total of 20,326 blood units were enrolled in this study, 39 donors were positive for HBV S gene in the nested-PCR. Mutations in the major hydrophilic region (MHR; aa 99-169) were identified by direct sequencing of S region. Results Among of 20,326 blood units in the Red Cross Transfusion Center of Nanjing from October 2008 to April 2009, 296 samples (1.46%, 296/20,326) were HBsAg positive in the 2 successive rounds of the ELISA test. In these HBsAg positive units, HBV S gene could be successfully amplified from 39 donors (13.18%, 39/296) in the nested-PCR. Sequence analysis revealed that 32 strains (82.1%, 32/39) belong to genotype B, 7 strains (17.9%, 7/39) to genotype C. Besides well known G145R, widely dispersed variations in the MHR of S region, were observed in 20 samples of all the strains sequenced. Conclusions HBV/B and HBV/C are dominant in Nanjing, China. The mutations in the MHR of HBsAg associated with disease diagnosis are common.
