Background: The course of hepatitis B virus (HBV) infection is not only determined by variations in viral virulence but may be influenced by host immune response, where Human Leukocyte Antigen (HLA) plays an important role. Objective: The purpose of the present study was to explore whether HLA-DRB13* allele of MHC gene had any influence in spontaneous recovery from HBV infection among Bangladeshi adults. Method: This cross sectional study was carried out at the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Bangladesh. A total of 90 randomly selected hepatitis B virus infected adult patients, consisting of 30 acute HBV infections, 30 chronic HBV infection and 30 healthy controls were selected according to selection criteria for evaluation of HLA DRB1*13 allele. Detection of HLA DRB1*13 allele was done by conventional PCR followed by agarose gel electrophoresis. Result: The study revealed a significant increase of DRB1*13 in acute hepatitis B (AHB vs HC-40% vs 6.7%, RR= 9.4; P value <0.05, AHB vs CHB=40% vs 10%; RR=2.27, P value <0.05) compared to chronic hepatitis B infected (HBV) patients and healthy controls (CHB vs HC-10% vs 6.7%, RR= 1.5, P>0.05). This is the first report on HLA DRB1* gene associations among hepatitis B (HBV) infected Bangladeshi patients. Conclusion: The present study revealed that HLA DRB1*13 was associated with protection against persistent HBV infection among acutely infected adult HBV patients in Bangladesh.

Abstract Background Interleukin-6 (IL-6) plays an important role in chronic inflammation. Thus, we aimed to investigate the effects of IL-6 polymorphisms in predicting the progression of hepatitis B virus (HBV) -related liver cirrhosis. Methods A cross-sectional study was conducted to analysis IL-6 polymorphisms and serum levels of IL-6 in HBV-infected patients of different clinical phases and in healthy controls. IL-6 polymorphisms were detected by Taqman PCR method and plasma IL-6 levels were assessed by ELISA. Results Our analysis included 182 chronic hepatitis B (CHB) patients, 190 HBV-infected liver cirrhosis cases, 125 inactive HBsAg carriers, and 246 healthy controls. Seven SNPs in IL-6 including rs10499563, rs17147230, rs1800796, rs2069837, rs1524107, rs2066992, rs2069852 were analyzed. In haplotype analysis between HBV-infected liver cirrhosis cases with CHB patients, inactive HBV-carriers or healthy controls, haplotype CT in block 1 and haplotype GGCGG in block 2 were associated with liver cirrhosis (P<0.05). What’s more, the genotype or allele frequencies were significantly different in IL-6 rs10499563 and rs2069837 when HBV-infected liver cirrhosis patients compared with CHB patients, inactive HBV-carriers or healthy controls. A further study found that compared with the controls or CHB patients, plasma IL-6 was elevated in HBV-infected liver cirrhosis patients (P<0.05). Conclusion In conclusion, the polymorphisms of the IL-6 rs10499563 and rs2069837 are associated with the susceptibility of liver cirrhosis may through their effects on IL-6 expressions and these two single nucleotide polymorphisms can be used as potential predicting markers for prognosis of HBV-infected liver cirrhosis.

Hepatitis B virus (HBV) can hijack the host bile acids (BAs) metabolic pathway during infection in cell and animal models. Additionally, microbiome was known to play critical role in the enterohepatic cycle of BAs. However, the impact of HBV infection and associated gut microbiota on the BA metabolism in chronic hepatitis B (CHB) patients is unknown. This study aimed to unveil the distinct BA profiles in chronic HBV infection (CHB) patients with no or mild hepatic injury, and to explore the relationship between HBV, microbiome and BA metabolism with clinical implications.Methods: Serum BA profiles were compared between CHB patients with normal ALT (CHB-NALT, n = 92), with abnormal ALT (CHB-AALT, n = 34) and healthy controls (HCs, n = 28) using UPLC-MS measurement. Hepatic gene expression in CHB patients were explored using previously published transcriptomic data. Fecal microbiome was compared between 30 CHB-NALT and 30 HCs using 16S rRNA sequencing, and key microbial function was predicted by PICRUSt analysis.Results: Significant higher percentage of conjugated BAs and primary BAs was found in CHB patients even without apparent liver injury. Combinatory BA features can discriminate CHB patients and HCs with high accuracy (AUC = 0.838). Up-regulation of BA importer Na+ taurocholate co-transporting peptide (NTCP) and down-regulation of bile salt export pump (BSEP) was found in CHB-NALT patients. The microbial diversity and abundance of Lactobacillus, Clostridium, Bifidobacterium were lower in CHB-NALT patients compared to healthy controls. Suppressed microbial bile salt hydrolases (BSH), 7-alpha-hydroxysteroid dehydrogenase (hdhA) and 3-dehydro-bile acid Delta 4, 6-reductase (BaiN) activity were found in CHB-NALT patients.Conclusion: This study provides new insight into the BA metabolism influenced both by HBV infection and associated gut microbiome modulations, and may lead to novel strategy for clinical management for chronic HBV infection.

Aims: The study was carried out among 120 dentists working in the selected hospitals of Dhaka city to find out the preventive practice on hepatitis B virus (HBV) infection. Methods: A descriptive type of cross-sectional study was carried out involving 120 dentists working in the selected hospitals of Dhaka city from December 2011 to March 2012 to quantify the preventive practice on HBV infection through a pretested semi-structured questionnaire. Results were analyzed by using the software SPSS 16.0 version (Chicago). Then analyzed data were presented according to the variables of the study showing percentage relationship between variables using appropriate statistical method.Results: Mean age of the dentists was 26.43±6.29 (range, 25-45) years where 74.17% were male and 25.83% were female. Among 120 respondents, 20.83% obtained BDS degree along with a postgraduate training (PGT) in any of the respective fields of dentistry. Others obtained MS in dentistry (21.67%), MPH in dentistry (10.83%), PhD in dentistry (9.17%), DDS in dental surgery (10%) and FCPS in dentistry (6.67%). Academic positions of the respondents were 33.33%, assistant professors, 26.67% associate professors, 19.17% medical officers, and 17.5% were lecturers. Majority (93.3%) dentists knew about HBV transmission, prevention, symptoms, risks, and concurrences. Out of them, 87.5% reported having been tested for HBV which was associated with their designations (p=0.013) and more than 75% reported having been vaccinated against HBV. Conclusions: A high level of knowledge and attitude towards practice in the prevention of HBV was found to be very good among the dentists of Dhaka city though seemed it was not always possible to take precaution for handling emergency patients. Further broad scale studies would be needed to have decisive results. DOI: http://dx.doi.org/10.3329/cdcj.v10i1.13831 City Dent. Coll. J Volume-10, Number-1, January-2013

IntroductionHepatitis B virus (HBV) is a bloodborne virus which can be transmitted via percutaneous and mucocutaneous exposure to infected body fluid. Healthcare workers (HCWs) who are continuously exposed to different body fluids are at an increased risk of contracting and transmitting this virus. It is thus important to evaluate the knowledge and attitude of HCWs towards HBV and the prevalence of HBV infection among them.MethodsThis cross-sectional study was carried out between April and September 2017. Overall, 398 HCWs were recruited for this study. Knowledge on the route of HBV transmission and attitude towards HBV were evaluated using a well-structured questionnaire. Hepatitis B surface antigen (HBsAg) positivity was obtained using the Monolisa HBsAg ULTRA kit (Bio-Rad). Data were analysed using SPSS V.20.ResultsAmong the HCWs who participated in this study, 338 (84.9%) had heard of HBV, and 269 (67.6%) of them had adequate knowledge on the route of HBV transmission. Medical doctors were the most knowledgeable among biomedical workers and students (76.5%). The rate of stigma was highest among nurses (87, 38.8%). The prevalence of HBsAg positivity was high (42, 10.6%) given that there is an efficient and available vaccine. Overall, over 70% of HCWs invited to participate in this study responded.ConclusionKnowledge on the route of HBV transmission was fair, and the level of stigmatisation of HBV-infected patients and the prevalence of HBV infection were high in this study. A sensitisation campaign should be carried out to educate HCWs on HBV, thus reducing the level of stigma associated with HBV as well as the probability of contracting HBV as a nosocomial infection.

BackgroundHepatitis B virus (HBV) infection is a major public health issue worldwide, with about 257 million people reported to be chronic carriers by the WHO fact sheet updated in 2018. HBV can be contracted via direct contact with infected body fluid and infection is almost always asymptomatic. Although healthcare workers (HCWs) are at high risk of HBV infection, little is known about the prevalence of the various HBV markers among HCWs in Cameroon. The present study was taken to evaluate the prevalence of different HBV serological markers among HCWs in the North-West Region of Cameroon.MethodsThis cross-sectional hospital-based study was carried out between April and September 2017 during which 395 HCWs were recruited. The serum of the HCWs were tested for the presence of HBV core antibody, hepatitis B surface antibody, hepatitis B e antibody and hepatitis B surface antigen using Monalisa ELISA kits produced by BIO-RAD laboratories. Data were analysed using SPSS V.20.0.ResultsAmong the 395 participants, 270 (68.4%) of them were females, 187 (47.3%) had been exposed to HBV, 145 (36.7%) had resolved the infection, 42 (10.6%) were current HBV carriers, 10 (2.5%) were infective, 36 (9.1%) were vaccinated and 172 (43.5%) were still susceptible. Exposure to HBV, past infection and susceptibility were significantly associated with age while the rate of vaccination was significantly associated with the job of the HCW in the health facilities.ConclusionThe prevalence of HBV exposure and infection among HCWs obtained in this study was high while the level of vaccination in this at-risk population was low. Adequate steps should be taken to sensitise this population on HBV and the vaccination procedure.

Hepatitis B vaccination is the most effective preventive measure in reducing the incidence of chronic hepatitis B virus (HBV) infection and its consequences such as cirrhosis, hepatocellular carcinoma, liver failure and death. Ghana introduced the universal HBV vaccination in the national Expanded Programme on Immunization in 2002. The current study sought to determine the sero-protection rate and the prevalence of HBV infection among fully vaccinated children in the West Gonja District in the Savanna Region of Ghana. This cross-sectional study recruited three hundred and fifty (350) fully vaccinated children who visited West Gonja Catholic Hospital from September to December 2019 for healthcare. Structured questionnaires were administered to obtain information on the demographics. The clinical history of the participants was obtained from the hospital records. Sera were separated from 2-5ml of blood sample collected from each participant after informed consent had been sought from their parents/guardians. Sera were tested for HBsAg, anti-HBs and anti-HBc using ELISA. Samples positive for HBsAg or anti-HBc were tested for HBV DNA by Real-Time Polymerase Chain Reaction. The overall sero-protection rate (anti-HBs titers ≥ 10 mIU/mL) among the studied participants was 56% with anti-HBs geometric mean titer (GMT) of 95.7 mIU/mL (± 6.0; 95% CI) compared with GMT of 2.8 mIU/mL (± 0.2; 95% CI) among non-seroprotected participants. There was no statistically significant difference in sero-protection rate between males and females (p-value = 0.93) and in relation to age (p-value = 0.20). The prevalence of HBV infection among studied participants as determined by the HBV DNA/HBsAg positivity was 1.4% while anti-HBc sero-positivity was 2%. Even though the sero-protection rate and HBV infection rate reported in the current study compares with that of other international studies further studies need to be conducted to understand the factors related to sero-protection and HBV infection rate in the Savanna Region of Ghana.

Background: Hepatitis B Virus (HBV) infection is a foremost global health problem. In the context of Nepal, the prevalence of HBV infection is found to be low, 0.9% (1.1% in males and 0.5% in females), though a high prevalence of ≥8% is shown among the population in the mountainous region by several studies. The epidemiology of HBV infection in the population of Jumla is not well-known. This study aimed to find out the seroprevalence of HBV surface antigen (HBsAg) in patients visiting Karnali Academy of Health Sciences Teaching Hospital (KAHS-TH), Jumla, Nepal. Methods: The cross-sectional study was conducted in people visiting KAHS-TH, Jumla for testing HBsAg from 1st April 2018 to 31st March 2019. The samples collected were tested for HBsAg by using the Rapid HBsAg test kit. All positive cases were further tested by the Chemiluminescence (CLIA) method for HBsAg. The data entry was done in Microsoft Excel. After transferring the data into SPSS version 16, data analysis was done.Results: In this study, 1704 individuals were screened during the period. Overall 53 (3.11%) were HBsAg positive. Among the total of 506 males and 1198 females, 22 (4.34%) males and 31 (2.58%) females were positive for HBsAg. The highest prevalence (8.1%) was observed in the age group of 40– 45 years. But the prevalence rate is zero in 0-5 years age group and above 65 years of age. Conclusion: The HBV infection was higher in Jumla as compared to that of the overall prevalence of Nepal. Males were highly infected than females and the middle age group was at the high-risk of HBV infection.

Hepatitis B virus (HBV) has long been recognized as an occupational risk for healthcare workers (HCWs) as a result of regular and routine exposure to blood and other body fluids in the course of their duties. The risk of occupational exposure to such infection has been the concerns of HCWs for years. However, there were scarcities of information on frequency of Hepatitis B virus infection in the study area. This study aimed to determine the seroprevalence of Hepatitis B surface antigenaemia among Health Care Workers in Babcock University Teaching Hospital, Ilisan, Nigeria. A descriptive, cross-sectional study conducted among HCWs from across various occupation categories in the study area between May and June 2015. A structured questionnaire was used to collect demographics and clinical data. Sample analytical process was carried out using the HBsAg commercially available kits (Genedia, Green Cross, Korea). Of the 100 HCWs enrolled in the study, HBsAg was detected in 7%. The positivity of HBsAg, in this study, was more among males and all were from staff younger than 50 years old. The occupational risk of HBV infection among the HCWs in this study was highest among the cleaning staff followed by nurses and doctors. None was documented among the Medical laboratory Scientists/technicians. The occupation risk of HBV infection among the HCWs in this study was high. Regular Infection prevention and control training is required and HBV vaccine should be more readily available for HCWs by coordinated institutional vaccination programs.

INTRODUCTION: Vaccination is the main tool for preventing hepatitis B virus (HBV) infection; however, following the completion of the vaccination series, the concentrations of anti-HBs can decline over the years and reach levels less than 10mIU/mL. The persistence of protection in these individuals is still unknown. The present study aimed to determine the anti-HBs antibody levels among children and adolescents who had received a complete vaccination course for hepatitis B. METHODS: Antibodies against HBV surface antigen (anti-HBs) were tested in 371 individuals aged 10 to 15 years-old. RESULTS: Volunteers who showed undetectable quantities of anti-HBs accounted for 10.2% of the population studied and 39.9% presented antibody titers of less than 10mIU/mL. Anti-HBs ≥ 10mIU/mL were verified in 49.9%. CONCLUSIONS: These results corroborate other studies indicating levels of anti-HBs below 10mIU/mL in vaccinated individuals. Additional studies are required to assess whether this indicates susceptibility to HBV infection and the need and age for booster doses.
