Correlates of chronic hepatitis B virus infection in the general adult population of China: Systematic review and meta-analysis. J Viral Hepat 2023; 30:470-488. [PMID: 36751939 DOI: 10.1111/jvh.13816] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 12/19/2022] [Accepted: 01/13/2023] [Indexed: 02/09/2023]
Abstract
Chronic infection with hepatitis B virus (HBV) is a significant public health issue in China. Understanding factors associated with chronic HBV is important to enable targeted screening and education and to improve early diagnosis and prevention of disease progression. This systematic review and meta-analysis aimed to identify and describe correlates of chronic HBV among Chinese adults. Searches were conducted in MEDLINE, EMBASE and grey literature up to 25 June 2020. Eligible papers included observational studies in adults of the general population in China that reported factors associated with chronic HBV, measured by Hepatitis B surface antigen (HBsAg). Meta-analysis was performed using fixed-effect models of HBsAg prevalence among factors, and of adjusted odds ratios (ORs) for chronic HBV associated with each factor. Overall 39 articles were included, covering 22 factors, including a range of sociodemographic, behavioural and medical factors. In meta-analysis of eligible studies, a range of factors were significantly associated with higher HBsAg prevalence, including middle age, male sex, being married, rural residence, lower education, smoking, having a HBsAg positive household contact, family history of HBV, history of surgery or blood transfusion. The adjusted ORs varied, from 1.11 (95% CI 1.05-1.18) for smoking to 5.13 (95% CI 4.99-5.26) for having a HBsAg positive household contact. In Chinese adults, a range of factors are associated with chronic HBV infection, which may help inform targeted screening in the general population.

Marjenberg Z, Wright C, Pooley N, Cheung KW, Shimakawa Y, Vargas-Zambrano JC, Vidor E. Hepatitis B surface antigen prevalence and the rates of mother-to-child transmission of hepatitis B virus after the introduction of infant vaccination programs in South East Asia and Western Pacific regions: a systematic review. Int J Infect Dis 2022; 124:65-75. [PMID: 36089151 DOI: 10.1016/j.ijid.2022.09.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 09/01/2022] [Accepted: 09/02/2022] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVES Infant vaccination against the hepatitis B virus began in the World Health Organization South East Asia Region and the Western Pacific Region between 1983 and 2016. This systematic review examined the seroprevalence of hepatitis B surface antigen (HBsAg) in children and the rate of mother-to-child transmission (MTCT) in these regions between 1990 and 2020. METHODS MEDLINE and EMBASE were searched for articles published between January 1990 and September 2020, which reported seroprevalence of HBsAg in children aged 0-15 years and/or the rate of MTCT in the South East Asia Region and Western Pacific Region. A pragmatic review identified supporting information. This review was registered in the International Prospective Register of Systematic Reviews (#CRD42020211707). RESULTS Of 115 included studies, 77 (24 countries) reported HBsAg prevalence, and 38 (nine countries) reported MTCT. The seroprevalence of HBsAg ranged between 0.0% and 27.4%, with a decreasing trend over time in each country. MTCT rates were 0.0-5.2% in infants of mothers who are hepatitis B e antigen-negative and 2.7-53.0% in infants of mothers who are hepatitis B e antigen-positive. CONCLUSION After the introduction of infant hepatitis B virus vaccination programs, the countries in South East Asia Region and Western Pacific Region observed a reduction in HBsAg seroprevalence in children. Nevertheless, the risk of MTCT persists, emphasizing the importance of antenatal screening to identify high-risk pregnancies.

Hepatitis B among University Population: Prevalence, Associated Risk Factors, Knowledge Assessment, and Treatment Management. Viruses 2022; 14:v14091936. [PMID: 36146743 PMCID: PMC9501279 DOI: 10.3390/v14091936] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 08/25/2022] [Accepted: 08/29/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Very few studies have been reported on hepatitis B in the State of Azad Jammu and Kashmir, Pakistan, and none of them are specific to the prevalence and causes of hepatitis B spread among educational institutes. This study aimed to estimate the prevalence of hepatitis B infection and its associated risk factors among the University of AJ and K population. Methods: An observational, cross-sectional, and analytical study was conducted with 7015 students and employees. Hepatitis B was detected by rapid immunochromatographic tests (ICTs), enzyme-linked immunosorbent assay (ELISA), and real-time quantitative PCR. A questionnaire and interview method was used to assess the disease knowledge and associated risk factors with hepatitis B through Chi-square, Fisher’s exact test, and paired t-test. Results: Of the participants, 150 (2.13%) were found positive for the hepatitis B surface antigen (57.3% male and 42.7% female). Only 0.3% participants were found fully vaccinated against the hepatitis B virus. Among ethnic groups, the Syed tribe was found more prevalent for hepatitis B infection (40.6%), while use of contaminated mourning blades (95% CI: p = 0.0001) was found as an overlooked risk factor. Hepatitis preventive awareness sessions were found to be very significant (p = 0.0001). Conclusions: The study showed that an overlooked risk factor is playing a key role in the spread of HBV in a tribe living worldwide, which must be addressed globally to eradicate hepatitis B. In Pakistan, a country-wide annual HBV vaccination program should be launched to control hepatitis B.

Abstract
This study aimed to determine the seroprevalence and determinants of hepatitis B virus (HBV) infection among university students in Bangladesh. This cross-sectional study was conducted among 614 students from five universities in central Bangladesh. Data were collected on demographic information, immunization history, medical and blood transfusion history through the face-to-face interview. Blood samples were collected and screened for anti-HBsAg using ELISA, HBsAg Rapid Test-cassette, and immune chromatographic test. The overall seroprevalence of HBV infection was 5.0%, and vaccination coverage was 19.2% among the participants. Students having a history of surgery (OR 11.004, 95% CI 3.211-37.707), blood transfusion (OR 5.651, 95% CI 0.965-33.068), being married (OR 4.776, 95% CI 1.508-15.127), and not being vaccinated (OR 9.825, 95% CI 1.130-85.367) were at higher risk of being infected by HBV. This study showed the endemicity of HBV infection among the Bangladeshi population. Marriage, surgical or blood transfusion history, not being vaccinated were the determinants of HBV infection within the study population. Public health initiatives for preventing HBV infection at the university levels should be envisaged.

Abstract
BACKGROUND Data on the epidemiology characteristics of hepatitis B surface antibodies (anti-HBs) are lacking among central southern undeveloped areas of China, especially for young adults. This study aims to demonstrate the sero-epidemiology characteristics of HBsAb among young adults. AIMS The aim of this study is to demonstrate the epidemiological characteristics in prevalence of serum anti-HBs in college students of a university in Hunan Province, China. METHODS Data were derived from the health records (including serum HBsAb data) among freshmen of a university from 2017 to 2019 in Hunan Province, China. RESULTS A total of 13,426 freshmen with complete data who were born in Hunan Province were collected. The 3-year total prevalence of anti-HBs in freshmen was 44.75% with no statistically significant sex difference, the prevalence of anti-HBs is 46.93%, 53.13%, and 34.79% for 2017, 2018, and 2019, respectively. There are significant geographic differences of prevalence of anti-HBs in freshmen from different areas. The lowest prevalence of anti-HBs was 31.80% in freshmen from Xiangtan, and the highest prevalence of anti-HBs was 53.10% in freshmen from Yongzhou. CONCLUSION The prevalence of serum anti-HBs among the freshmen in Hunan from 2017 to 2019 is much lower than the average national level, and the prevalence in 2019 is significantly lower than that in 2017 and 2019. There are significant differences in different time and areas of the prevalence of anti-HBs. There is a necessity to carry out area-specific intensive immunization plan in a timely manner among young population in Hunan Province, China.

Abstract
Chronic hepatitis B (HBV) remains a significant public health problem in Ghana and past reviews conducted could not calculate a nationwide prevalence of the disease due to lack of primary research for some regions of the country. We therefore conducted this study to summarize and update the available information on HBV infection burden (prevalence) in Ghana from 2015–2019.We systematically searched PubMed, Embase, ScienceDirect, and Google Scholar to retrieve primary studies published in peer-reviewed journals from November 2015 to September 2019, assessing the prevalence of HBV among the Ghanaian populace. The review included 21 studies across all ten old regions of Ghana with a total sample population of 29 061. The HBV prevalence was estimated for subpopulations as follows: 8.36% in the adult population, 14.30% in the adolescent population, and 0.55% in children under five years (pre-school). Among adults, HBV infection prevalence was the highest in the special occupation group (14.40%) and the lowest prevalence rate of 7.17% was recorded among blood donors. Prevalence was lower in the north than in the southern part of the country. The Ashanti region had the most studies at 6/21 (29%), while no study was identified for the Upper West region. Across the country, the highest HBV infection prevalence rates were recorded in the age group of 20–40 years. The burden of hepatitis B is enormous and remains an important public health issue in Ghana. Addressing the issue will require an integrated public health strategy and rethinking of the implementation gaps in the current HBV infection control program. This will help propel the country towards eliminating the disease by 2030.

Abstract
Beijing–Tianjin–Hebei is the largest urban agglomeration in northern China, but the spatiotemporal patterns and risk factors concerning hepatitis B virus (HBV) incidence in this area have been unclear. The present study aimed to reveal the spatiotemporal epidemiological features of HBV infection and quantify the association between HBV infection and socio-economic risk factors. The data on HBV cases in Beijing–Tianjin–Hebei from 2007 to 2012 was collected for each county. The Bayesian space–time hierarchy model and the GeoDetector method were used to reveal spatiotemporal patterns and detect risk factors. High-risk regions were mainly distributed in the underdeveloped rural areas in the north and mid-south of the study region, while low-risk regions were mainly distributed in the urban and western areas. The HBV annual incidence rate decreased substantially over the 6-year period, dropping from 7.34/105 to 5.51/105. Compared with this overall trend, 38.5% of high-risk counties showed a faster decrease, and 35.9% of high-risk counties exhibited a slower decrease. Meanwhile, 29.7% of low-risk counties had a faster decrease, and 44.6% of low-risk counties exhibited a slower decrease. Socio-economic factors were strongly associated with the spatiotemporal patterns and variation. The population density and gross domestic product per capita were negatively associated with HBV transmission, with determinant powers of 0.17 and 0.12, respectively. The proportion of primary industry and the number of healthcare workers were positively associated with the disease incidence, with determinant powers of 0.11 and 0.8, respectively. The interactive effect between population density and the other factors exerted a greater influence on HBV transmission than that of these factors measured independently.

Abstract
Background The epidemiology of hepatitis B virus (HBV) infection in the general population in Rwanda is not well known. This study examined the prevalence of HBV surface antigen (HBsAg) positivity and associated risk factors among people aged 25 years and over in an organized national screening campaign. Methods This is a cross-sectional study using data from a nationwide HBV screening campaign organized by the Rwanda Biomedical Centre from March to October 2018. This campaign targeted individuals aged > 25 years old from 24 of 30 districts of Rwanda. Sensitization was done through multimedia announcements, community health workers and local church leaders. During the campaign, a structured interview was administered by trained healthcare workers to collect information on socio-demographic, clinical and behavioral characteristics of participants; HBV screening was performed with HBsAg using enzyme-linked immunosorbent assays (ELISA) testing. Bivariate and multivariate logistic regressions were used to assess factors associated with HBsAg positivity in the screened participants. Results A total of 327,360 individuals were screened during the campaign. Overall 12,865(3.9%) were HBsAg positive. The highest prevalence (4.2%) was found in the 35–44-year-old group, but the difference from other groups was not significant (Odds Ratio [OR = 1.057, 95% Confidence Interval(CI) (0.904–1.235)]. Being male [OR = 1.348, 95% CI (1.30,1.40)]; being single [OR = 1.092, 95% CI (1.10–1.16)] compared to married; a previous positive TB screening test [OR = 2.352, 95% CI (1.63–3.39)]; history of surgical operation [OR = 1.082, 95% CI (1.00,1.17)]; exposure to traditional operational practices and scarification [OR = 1.187, 95% CI (1.13, 1.24)]; and having a person in the family with viral hepatitis [OR = 1.367, 95% CI (1.21, 1.53)] were significantly associated with HBV infection. Conclusions These data provide the first national estimate of the prevalence of HBsAg seropositivity and its associated factors in Rwanda. The study identified people with the highest risk of HBV infection who should be the priority of future prevention efforts in Rwanda and in similar settings.

Abstract
Although central Africa is classified as having a high endemicity of hepatitis B virus (HBV) and hepatitis D virus (HDV) infection, there is paucity of prevalence studies. For the first time on a country-wide level in Central Africa, we show in Gabon an overall 7.4% prevalence of Hepatitis B surface antigen (HBsAg) and that more than 25% of the HBsAg-positive population are infected by HDV. Although HBV prevalence did not differ significantly between provinces, there is a north-south split in the distribution of HDV seroprevalence, with the highest rates (>66.0%) correlating with the presence of specific ethnic groups in the northeastern provinces. Genotyping revealed high genetic diversity of the HBV and HDV strains circulating in Gabon, including many restricted to this region of the globe. This work confirmed that high exposure to HBV and HDV infection reported in selected regions of Gabon holds true across the whole country.

Abstract
Hawai'i has one of the highest rates of liver cancer in the United States. This is in large part due to undiagnosed chronic hepatitis B (CHB) infection among foreign-born Asian and Pacific Islanders (APIs). In order to estimate the prevalence of CHB infection among foreign-born APIs in Hawai'i, the Hawai'i State Department of Health conducted a cross-sectional study from August 2013 through August 2015 of patients of a federally qualified health center serving the largest population of medically underserved APIs in the state. Among 1261 patients surveyed, the prevalence of CHB infection (based on HBsAg seropositivity) was 5.6% (71/1259). No significant differences were detected by place of birth, age, or gender; however, the adjusted prevalence ratio of CHB infection was 6.0 times higher among persons reporting household contact with hepatitis B virus compared with those without such contact. Our findings underscore the need for targeted screening of at-risk individuals and their household contacts.

Aetiology of viral hepatitis among jaundiced patients presenting to a tertiary hospital in Ghana. PLoS One 2018; 13:e0203699. [PMID: 30208084 PMCID: PMC6135398 DOI: 10.1371/journal.pone.0203699] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Accepted: 08/24/2018] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Viral hepatitis continues to play significant role in causing morbidity and mortality in sub-Saharan Africa. Apart from the few population based studies available, not many have investigated the burden of these viruses in jaundiced patients. Among the few studies, hepatitis E is the least studied among jaundiced patients. This study was aimed at describing the frequency, distribution and risk of the different hepatitis viruses among jaundiced patients reporting to the second largest teaching hospital in Ghana. METHODS From November, 2015 to April, 2016, a cross-sectional study was conducted among jaundiced patients attending the Komfo Anokye Teaching Hospital. Between 3-5 ml of blood was collected from each patient and screened for viral hepatitis agents using both serologic and molecular-based assays. RESULTS In the 155 patients recruited, hepatitis B was the most prevalent [54.2% (95% CI = 46.0%-62.2%)] followed by hepatitis E [32.9% (95% CI = 25.6-40.9%)]. Most cases of hepatitis E occurred as co-infections with hepatitis B (18%), with the predominant clinical feature being hepatocellular carcinoma. Risk factor variable analysis showed middle and older aged individuals were more at risk of hepatitis B exposure whereas younger age groups (<18 years) were more at risk of hepatitis E virus infection. CONCLUSION Hepatitis viruses are still important in the viral aetiology of jaundice in Ghana. Hepatitis B and hepatitis E co-infections could play significant roles in causing severe disease. A more aggressive approach needs to be adopted in order to reduce the morbidity and mortality associated with hepatitis causing viruses in Ghana and other developing countries.

Abstract
INTRODUCTION Observational studies evaluating the association between chronic hepatitis B (CHB) and risk of metabolic syndrome (MetS) have yielded inconclusive results. OBJECTIVE The current meta-analysis was conducted to identify whether CHB infection plays a role in the risk of MetS and its components. METHODS The electronic search of MEDLINE, PubMed Central, and EMBASE databases was systematically performed from their inception until February 2017 to identify all eligible studies. The most adjusted risk estimates and their corresponding 95% confidence intervals (CIs) for the associations of chronic hepatitis B with MetS and its components were collected and analyzed. RESULTS A total of 13 studies, with a total sample size of 138,994,999 subjects and 35,481,231 individuals with MetS were included in this Meta-analysis. The results of pooled analysis revealed that CHB infection is related to reduced risk of MetS (OR=0.83, 95%CI=0.71-0.79, random effects), with evidence of significant heterogeneity (I2=89%, P<0.001). This association was an age, gender, and ethnicity-dependent relationship. Moreover, CHB was associated with reduced risk of elevated blood pressure, reduced HDL-cholesterol, increased fasting glucose, and, most strongly with increased triglycerides in some subgroups. The sensitivity analyses confirmed the stability of the results. CONCLUSIONS This meta-analysis suggests that CHB is associated with decreased risk of MetS and some of its single components.

Abstract
OBJECTIVES To reveal the prevalence and associated influencing factors of hepatitis B among a rural residential population in Zhejiang, China, in order to help develop specific control strategies. METHODS We conducted a cross-sectional study among a rural residential population in Zhejiang, China. Stratified multistage cluster sampling was utilised in five districts; a structured questionnaire was used to collect the information such as age, gender, education, occupation, living status, and other health related information of the participants by trained local staff; and the hepatitis B virus (HBV) infection status of the participants was determined by the chemiluminescence immunoassay test. Univariate and multivariate analyses were applied to evaluate the influencing factors of HBV infection. The odds ratio of each related factor was assessed with or without adjustment separately. RESULTS The mean age of the 16 601 participants (7881 males and 8720 females) who completed the survey was 40.28±19.47 years. The positive rate of hepatitis B surface antigen (HBsAg) was 4.04% (95% CI 3.74% to 4.35%), and 3.85% when standardised by age and gender. Univariate analysis showed that age, educational level, occupation, living status, history of hepatitis B examinations, history of blood transfusion, vaccination, family history, coastal living, and district were the potential influencing factors. Multivariate logistic regression indicated that occupation, living status, history of hepatitis B examinations, vaccination and district were the influencing factors. Undertaking a service-based tertiary industry job (ORa 1.19, 95% CI 0.94 to 1.51) and non-single living (ORa 2.84, 95% CI 2.17 to 3.70) might be risk factors, while vaccination (ORa 0.43, 95% CI 0.34 to 0.53) and history of hepatitis B examinations (ORa 0.71, 95% CI 0.48 to 1.03) were potential protective factors. CONCLUSIONS The prevalence of hepatitis B is at an intermediate epidemic level in a rural residential population in Zhejiang, China. Raising vaccination coverage, especially in adults, is a suitable strategy for the prevention and control of hepatitis B.

Abstract
BACKGROUND Hepatitis B is a disease that affects the liver and is caused by the hepatitis B virus (HBV). Hepatitis B is a serious public health problem in China. The objective of this study was to assess knowledge of and behaviours towards the transmission and prevention of hepatitis B of new military recruits in China. METHODS A cross-sectional study was conducted among 800 new military recruits. A self-administered, structured questionnaire was used to collect information, and 727 questionnaires were returned completed. Analysis was performed using SPSS 18.0, and P < 0.05 was considered statistically significant. RESULTS Of the respondents, 665 (91.5%) were male and 62 (8.5%) were female. The mean age was 18.9 ± 1.7 years. A total of 608 respondents (83.6%) demonstrated poor knowledge and 119 (16.4%) adequate knowledge about HBV. Older age, female and higher education level were statistically associated with a higher mean knowledge score. Multivariate logistic regression showed that age (OR = 3.040, 95%CI 1.724-5.359, P < 0.001) and gender (OR = 1.791, 95%CI 1.325-2.421, P < 0.001) were significantly associated with appropriate behavioural practices towards prevention of HBV. CONCLUSION Against a backdrop of high HBV prevalence in China, new military recruits had poor knowledge of HBV. New recruits need better education about HBV to assist in reducing and preventing HBV infection.

Abstract
Limited information is available about the current epidemic status of hepatitis B virus (HBV) in Guangdong province in South China, where hepatitis B is endemic. We sought to provide an up-to-date assessment of hepatitis B prevalence in a large population through a community-based study. A total of 169,211 local residents were recruited using the stratified cluster random sampling method from 2014 to 2015, and each participant's information was collected using an interviewer-administered questionnaire. Accordingly, the prevalence of hepatitis B surface antigen (HBsAg) in the total population was 8.76%. HBsAg prevalence was lowest (0.29%) among children aged 0-12 years and highest (12.71%) among those aged 23-59 years. Moreover, the prevalence (8.82%) in males approximately equalled that (8.65%) in females (P > 0.05). Overall, vaccination was effective in preventing HBV infection, regardless of age. Among adults aged 23-59 years, male sex tended to keep the HBsAg persistence. However, reduced persistence for participants with occasional physical exercise and drinking was observed. For participants older than 59 years, a history of prior surgery placed people at high risk for infection. Although Guangdong has successfully decreased the HBsAg prevalence among children, it is urgent to expand vaccination to adults, and employ interventions to reduce the infection risk.

Abstract
The objective of this study was to determine the prevalence of serum HBsAg among adults in Henan province, China. A provincial serosurvey of people aged 18-74 years was conducted and individuals for analysis were selected using a multistage stratified random cluster sampling method. A 5-ml serum sample from each person was collected and the serum was tested for the presence of HBsAg, HBcAb, HBsAb, HBeAg, and HBeAb by ELISA. Multivariate analysis was used to identify factors associated with the prevalence of HBsAg. A total of 16,685 residents, aged 18-74 years who resided in 60 communities or villages in Henan, China were surveyed. Among the eligible study population, 642 HBsAg positive cases (3.7%) were found. The prevalence increased steadily from 3.1% among population aged 18-35 years old, to 5.1% among population aged 55-74 years. Accordingly, HBsAb declined steadily from 53.4% to 24.7%. Six hundred and forty-two positive HBsAg blood samples were screened for the HBeAg and HBeAb. HBeAg prevalence declined steadily from 27.7% among population age 18-35 years old to 6.8% among population age 55-74 years old. The single factor analysis was used for 16 possible risk factors and multivariate analysis showed that five risk factors were significantly related to HBV infection. HBV infection is a serious public health problem among adult population in Henan. Strengthening administrative regulations of medical practices, especially in rural areas, and providing health education propaganda to the public of HBV infection should be given more attention on public health policy.

Abstract
There is still no suitable routine hepatitis B immunization strategy for adults in China. To establish an optimal vaccination schedule for healthy adults, we investigated various schedules in healthy adults. In this randomized 5143 healthy adults received 10 μg hepatitis B vaccine at 0, 1 and 3 months(group A), 0, 1 and 6 months(group B), or 0, 1 and 12 months(group C). Blood samples were collected after 1 month and 12 months after the third dose. The geometric mean titer (GMT), seroconversion rate (levels of anti-HBs ≥ 10 mIU/mL) and high response rate (levels of anti-HBs ≥ 100 mIU/mL) were assayed. In our study, 2438 healthy adults finished the full vaccination program and follow-up. The seroconversion/sero-protective rate of groups A-C at one and 12 month after administration of the third vaccine dose was 100%, 99.9% and 97.9% verse 64.9%, 75.7% and 79.0%, respectively. GMT for anti-HBs tested in group A to C within 1 or 12 month after the third vaccination was 213.16, 432.58 and 451.47 mIU/ml verse 22.07, 46.70 and 56.18 mIU/ml, respectively. There were significant differences of seroconversion/sero-protective rate and GMT among the 3 groups (p < 0.01). Given the high anti-HBs seroconversion rate and GMT in all 3 groups, a flexible schedule for Hepatitis B vaccine should be recommended to adults, but 0-1-12 schedule is a better choice.

Abstract
The hepatitis B prevalence rate in adults is still at a high to intermediate level in China. Our purpose was to explore the incidence rate and protective immune barrier against hepatitis B in adults in China. A sample of 317961 participants was multi-screened for hepatitis B surface antigens (HBsAg) in a large-scale cohort of the National Hepatitis B Demonstration Project. A total of 5401 persons were newly-infected, representing an incidence rate of 0.81 (95% CI: 0.77–0.85) per 100 person-years after adjusted by gender and age. History of acquired immune deficiency syndrome, birth prior to 1992, coastal residence, family history of HBV, and migrant worker status were significantly associated with higher incidence, while HBV vaccination and greater exercise with lower incidence. The hepatitis B surface antibody (HBsAb) positive rate was negatively correlated with the incidence rate of hepatitis B (r = −0.826). Linear fitting yielded an incidence rate of 1.23 plus 0.02 multiplied by HBsAb positive rate. The study firstly identified the HBsAg incidence rate, which was reduced to 0.1 per 100 person-years after vaccination coverage of about 64%. The protective immune barrier against hepatitis B needs to be established in individuals born prior to the advent of infant HBV vaccination.

Abstract
OBJECTIVES In epidemiological studies, it is important to identify independent associations between collective exposures and a health outcome. The current stepwise selection technique ignores stochastic errors and suffers from a lack of stability. The alternative LASSO-penalized regression model can be applied to detect significant predictors from a pool of candidate variables. However, this technique is prone to false positives and tends to create excessive biases. It remains challenging to develop robust variable selection methods and enhance predictability. MATERIAL AND METHODS Two improved algorithms denoted the two-stage hybrid and bootstrap ranking procedures, both using a LASSO-type penalty, were developed for epidemiological association analysis. The performance of the proposed procedures and other methods including conventional LASSO, Bolasso, stepwise and stability selection models were evaluated using intensive simulation. In addition, methods were compared by using an empirical analysis based on large-scale survey data of hepatitis B infection-relevant factors among Guangdong residents. RESULTS The proposed procedures produced comparable or less biased selection results when compared to conventional variable selection models. In total, the two newly proposed procedures were stable with respect to various scenarios of simulation, demonstrating a higher power and a lower false positive rate during variable selection than the compared methods. In empirical analysis, the proposed procedures yielding a sparse set of hepatitis B infection-relevant factors gave the best predictive performance and showed that the procedures were able to select a more stringent set of factors. The individual history of hepatitis B vaccination, family and individual history of hepatitis B infection were associated with hepatitis B infection in the studied residents according to the proposed procedures. CONCLUSIONS The newly proposed procedures improve the identification of significant variables and enable us to derive a new insight into epidemiological association analysis.

World J Gastroenterol 2015; 21:7842-7850. [PMID: PMID : 26167084 PMCID: PMC4491971 DOI: 10.3748/wjg.v21.i25.7842] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2014] [Revised: 02/09/2015] [Accepted: 03/27/2015] [Indexed: 02/06/2023] Open
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
AIM: To evaluate the prophylactic efficacy of hepatitis B immunoglobulin (HBIG) in combination with different nucleos(t)ide analogues.
METHODS: A total of 5333 hepatitis B surface antigen-positive patients from the China Liver Transplant Registry database were enrolled between January 2000 and December 2009. Low-dose intramuscular (im) HBIG combined with one nucleos(t)ide analogue has been shown to be very cost-effective in recent reports. Hepatitis B virus (HBV) prophylactic outcomes were compared based on their posttransplant prophylactic protocols [group A (n = 4684): im HBIG plus lamivudine; group B (n = 491): im HBIG plus entecavir; group C (n = 158): im HBIG plus adefovir dipivoxil]. We compared the related baseline characteristics among the three groups, including the age, male sex, Meld score at the time of transplantation, Child-Pugh score at the time of transplantation, HCC, pre-transplantation hepatitis B e antigen positivity, pre-transplantation HBV deoxyribonucleic acid (HBV DNA) positivity, HBV DNA at the time of transplantation, pre-transplantation antiviral therapy, and the duration of antiviral therapy before transplantation of the patients. We also calculated the 1-, 3- and 5-year survival rates and HBV recurrence rates according to the different groups. All potential risk factors were analyzed using univariate and multivariate analyses.
RESULTS: The mean follow-up duration was 42.1 ± 30.3 mo. The 1-, 3- and 5-year survival rates were lower in group A than in groups B (86.2% vs 94.4%, 76.9% vs 86.6%, 73.7% vs 82.4%, respectively, P < 0.001) and C (86.2% vs 92.5%, 76.9% vs 73.7%, 87.0% vs 81.6%, respectively, P < 0.001). The 1-, 3- and 5-year posttransplant HBV recurrence rates were significantly higher in group A than in group B (1.7% vs 0.5%, 3.5% vs 1.5%, 4.7% vs 1.5%, respectively, P = 0.023). No significant difference existed between groups A and C and between groups B and C with respect to the 1-, 3- and 5-year HBV recurrence rates. Pretransplant hepatocellular carcinoma, high viral load and posttransplant prophylactic protocol (lamivudine and HBIG vs entecavir and HBIG) were associated with HBV recurrence.
CONCLUSION: Low-dose intramuscular HBIG in combination with a nucleos(t)ide analogue provides effective prophylaxis against posttransplant HBV recurrence, especially for HBIG plus entecavir.

Abstract
BACKGROUND Few studies were conducted on hepatitis B and C virus (HBV and HCV, respectively) risk factors among Chinese blood donors in recent years since voluntary donors replaced commercial donors. STUDY DESIGN AND METHODS A case-control survey was conducted in HBV- or HCV-positive and -negative donors from five blood centers in China between September 2009 and April 2011. Case status was defined by having a reactive result on Monolisa HBsAg Ultra (Bio-Rad) for HBV and Ortho anti-HCV EIA 3.0 (Johnson & Johnson) for HCV. Controls were randomly selected qualified blood donors matched to cases by donation month and blood center. Specific test-seeking, medical-related, and behavioral risk factors were compared by HBV and HCV status using chi-square tests or Fisher's exact tests with Bonferroni correction. RESULTS A total of 364 HBV cases, 174 HCV cases, and 689 controls completed the survey; response rates were 66.2, 47.3, and 82%, respectively. HCV-positive donors were significantly more likely to report having a blood transfusion history (23.4% vs. 3.0%, p < 0.0001) and ever living with a person with illegal drug injection (6.0% vs. 0.5%, p < 0.0001) than controls. Having intravenous and intramuscular injections in the past 12 months and ever having a tattoo are marginal risk factors for HCV (p values < 0.01). No specific risk factor for HBV was identified. CONCLUSION History of previous transfusion and living with illegal drug users are risk factors for HCV infection among Chinese blood donors from five regions. Test-seeking behavior is not associated with HBV or HCV infections.

Abstract
Hepatitis B immunization programs for newborns, children, and adolescents in China have shown remarkable results. To establish whether there would be any benefit in extending the program to cover older individuals, we examined both the epidemiology of hepatitis B virus (HBV) infection and the coverage of hepatitis B vaccinations among adults born before routine vaccinations were implemented. We then evaluated the impact of hepatitis B vaccination in adults aged 20-59 years. A large-scale cross-sectional epidemiological survey of HBV infection was performed in the province of Jiangsu, south-east China, between September 2009 and March 2010. A total of 86,732 adults aged 20-59 years were included, of which 8,615 (9.9%, 95% CI = 9.7-10.1%) were HBsAg sero-positive. Self-reported vaccination status suggested that the coverage was approximately 23.7% (95% CI = 23.4-24.0%). It was shown that higher HBV vaccination coverage was associated with a lower rate of HBsAg seropositivity among adults. There was a negative correlation between hepatitis B vaccination coverage and HBsAg prevalence (correlation coefficient = -0.805, p = 0.016), which might demonstrate the combined effects of vaccination and pre-vaccination HBsAg screening. In the unvaccinated group, the HBsAg-positive rate had an obvious upward trend with age growing among 20-39 year-olds (Trend χ2 = 22.605, P<0.001), while the vaccinated group showed no such trend (Trend χ2 = 3.462, P = 0.063). Overall, hepatitis B vaccination in adults might reduce the rate of HBsAg positivity. Therefore, routine immunization of adults aged 20-39 years should be seriously considered.

Abstract
BACKGROUND The tumor burden before liver transplantation indicates that hepatitis B virus (HBV) may hide in the extrahepatic and micrometastatic sites which serve as a source of HBV replication. Currently, many liver transplant centers, especially in Western countries, use the Milan or UCSF criteria to select patients with hepatocellular carcinoma for liver transplantation. This study was undertaken to compare the HBV prophylactic outcomes in two groups of living donor liver transplantation (LDLT) recipients. Patients in group A met the Milan criteria and those in group B exceeded the Milan criteria but were within the UCSF criteria. METHODS A database of adult-to-adult right-lobe LDLT performed at our institution for HBV-related hepatocellular carcinoma within the Milan or UCSF criteria between June 2002 and May 2012 was used to compare the HBV prophylactic outcomes between patients within the Milan criteria (group A, 41 patients) and those exceeding the Milan criteria but within the UCSF criteria (group B, 19 patients). RESULTS The 1-, 3-, and 5-year survival rates were similar between groups A and B (87.8%, 85.1% and 74.0% vs 73.3%, 61.1% and 61.1%, respectively, P=0.067). HBV recurred in 1 patient in 3.1 months after LDLT in group A and in 2 patients in group B (1 in 11.9 months and 1 in 24.1 months after LDLT). The 1-, 3-, and 5-year HBV recurrence rates were 2.6%, 2.6% and 2.6% in group A, and 7.3%, 17.9% and 17.9% in group B, respectively (P=0.118). CONCLUSION LDLT recipients who exceed the Milan criteria but remain within the UCSF criteria may have post-transplant HBV prophylactic outcomes similar to those who meet the Milan criteria.

Abstract
BACKGROUND Hepatitis B/C viruses cause liver disease and metabolic disturbances. AIMS The purpose of this study was to evaluate the association between hepatitis B/C infection and metabolic syndrome (MS). METHODS In total, 26,305 subjects were included in this multicentre, cross-sectional study. Systolic and diastolic blood pressures, body mass index and waist circumference were measured. Total cholesterol, high- and low-density lipoprotein cholesterol, triglyceride, fasting blood glucose and uric acid were determined, and hepatitis B serum antigen (HBsAg) and anti-HCV antibodies were assayed using commercial kits. RESULTS MS was diagnosed in 2712 (23.0%) females, including 131 and 166 positive for HBsAg and anti-HCV respectively. In the men, 4594 (31.6%) were diagnosed with MS, including 326 positive for HBsAg and 131 positive for anti-HCV. No significant difference in the prevalence of MS was identified in any group, except men and women >45 years who were anti-HCV positive. Various metabolic alterations in both men and women >45 years were noted, including waist circumference, body mass index, fasting blood glucose and systolic and diastolic blood pressure. Notably, high- and low-density lipoproteins were significantly lower in positive subjects compared to those weakly positive and/or negative for anti-HCV. CONCLUSIONS There were obvious metabolic derangements in patients coinflicted with MS and hepatitis C infections, particularly those >45 years of age. There is a pressing need to identify strategies to improve/resolve metabolic derangements to maximize sustained virological response rates in patients infected with HCV (and potentially HBV).

Abstract
Background Hepatitis B virus (HBV) infection is highly endemic in China and it threats human health seriously. The hepatitis B surface antigen (HBsAg) prevalence among women of childbearing age plays an important role in mother to child transmission of HBV, as 30% ~50% of chronic carriers can be attributed to maternal-infantile transmission. However, there are few studies which have reported on the prevalence of HBsAg among women of childbearing age in China. This study aimed to determine the prevalence of HBsAg and its associated risk factors among rural women of childbearing age in Hainan, which is the highest hepatitis B virus endemic province in China. Methods A cross-sectional, population-based study, which included 12393 rural women aged 15 ~ 49 years, enrolled by a multistage stratified cluster sampling, was carried out in Hainan province, China, from November 2007 to December 2008. Blood samples were obtained from each study participant, and screened for HBsAg. Results The overall HBsAg prevalence of childbearing age women was 9.51%. Risk factors for HBsAg positivity among rural women were: lower education level (OR=1.206), lower family monthly income (OR=1.233), having an HBsAg-positive family member (OR=1.300), without an immunization history (OR=1.243), tattooing (OR=1.190), body piercing (OR=1.293), vaginoscopy history (OR=1.103) and history of induced abortion (OR=1.142). Conclusions There is a high HBsAg seroprevalence rate among rural women of childbearing age in Hainan province. Hence, it is necessary to take preventive measures to reduce the seroprevalence of HBsAg and to control its associated risk factors.

Abstract
Background Susceptibility to viral infections as well as their severity are higher in men than in women. Heightened antiviral responses typical of women are effective for rapid virus clearance, but if excessively high or prolonged, can result in chronic/inflammatory pathologies. We investigated whether this variability could be in part attributable to differences in the response to the Toll-Like Receptors (TLR) more involved in the virus recognition. Methods Cytokine production by peripheral blood mononuclear cells (PBMCs) from male and female healthy donors after stimulation with Toll-like receptors (TLR) 3, 7, 8, 9 ligands or with viruses (influenza and Herpes-simplex-1) was evaluated. Results Compared to females, PBMCs from males produced not only lower amounts of IFN-α in response to TLR7 ligands but also higher amounts of the immunosuppressive cytokine IL10 after stimulation with TLR8 and TLR9 ligands or viruses. IL10 production after TLR9 ligands or HSV-1 stimulation was significantly related with plasma levels of sex hormones in both groups, whereas no correlation was found in cytokines produced following TLR7 and TLR8 stimulation. Conclusions Given the role of an early production of IL10 by cells of innate immunity in modulating innate and adaptive immune response to viruses, we suggest that sex-related difference in its production following viral nucleic acid stimulation of TLRs may be involved in the sex-related variability in response to viral infections.
