Introduction: Hepatitis B infection is a serious global public health problem. The aim of the study was to assess the seroprevalance of hepatitis B surface antigen (HBsAg), as well as the risk factors associated with hepatitis B virus (HBV) infection among pregnant women attending antenatal care clinics of the University Hospital in Antioch, Turkey. Methodology: This descriptive cross-sectional study was carried out between May 2016 and December 2016. The Chi-squared was utilized to estimate the statistical significance of the association between socio-demographic variables and HBsAg status. The results were generated as proportions odds ratio (OR) with their 95% confidence intervals (Cl) and calculated by using both univariate and multivariate logistic regression analysis. Results: The seroprevalence of HBsAg was found to be 2.1%. A significant association was observed between age and HBsAg seropositivity (p = 0.027). History of blood transfusion (AOR = 9.51, 95% CI = 1.92-46.80, p = 0.006), history of hepatitis (AOR = 11.13, 95% CI = 2.02-61.28, p = 0.006), tattooing (AOR = 13.64, 95% CI = 2.52-73.76, p = 0.002) and a history of household/close contact (AOR = 11.10, 95% CI = 1.56-78.65, p = 0.016) were significantly associated with the risk of HBV infection. Conclusions: Data regarding the seroprevalence of HBsAg and risk factors associated with HBV infection in pregnant women plays a crucial role in evaluating the effectiveness of the public health protection policies and the strategies to control the disease.

In Denmark, universal screening of pregnant women for hepatitis B has been in place since November 2005, with the first two years as a trial period with enhanced surveillance. It is unknown what the change to universal screening without enhanced surveillance has meant for vaccination coverage among children born to hepatitis B surface antigen (HBsAg)-positive mothers and what risk factors exist for incomplete vaccination. This retrospective cohort study included 699 children of mothers positive for HBsAg. Information on vaccination and risk factors was collected from central registers. In total, 93% (651/699) of the children were vaccinated within 48 hours of birth, with considerable variation between birthplaces. Only 64% (306/475) of the children had received all four vaccinations through their general practitioner (GP) at the age of two years, and 10% (47/475) of the children had received no hepatitis B vaccinations at all. Enhanced surveillance was correlated positively with coverage of birth vaccination but not with coverage at the GP. No or few prenatal examinations were a risk factor for incomplete vaccination at the GP. Maternity wards and GPs are encouraged to revise their vaccination procedures and routines for pregnant women, mothers with chronic HBV infection and their children.

The Mean

Background: Hepatitis B Viral (HBV) infection is a potentially fatal infection of public health importance globally. Pregnant women and their unborn children are at risk of this infection due to its mode of transmission especially when in contact with infected body fluids and from mother to child transmission respectively. The prevalence of HBV infection in Nigeria is 13.6%. Aim: To determine the prevalence of HBV infection amongst pregnant women in rural community in southern Nigeria. Methods: This was a retrospective cross sectional study of pregnant women at Ogoni Primary Health Centers and General Hospitals in Southern Nigeria carried over a 4-month period. Serological test results for Hepatitis B surface antigen (HBsAg) of subjects were retrieved from the laboratories. Permission was gotten from Director of Public Health Rivers State Ministry of Health. The information gotten was analyzed using independent t test, chi square and fisher exact tests. Significance level was set at 0.05. Result: One hundred and eighty-five pregnant women were recruited for the study. The mean age of the antenatal clinic attendees was 28 ± 2 years, the mean gestational age at booking was 25 weeks and the mean parity was 2. Majority had secondary level of education represented by 122 (66%). Fifteen (8.1%) of the pregnant women were positive for Hepatitis B surface antigen. Conclusion: The prevalence of HBV infection was 8.1% in Ogoni southern Nigeria. This is worisome, hence preventive measures including HBV vaccines should be made available to the populace.

Abstract Background: Hepatitis B is a potentially life-threatening liver infection and a major global health problem. It causes chronic infection and puts people at high risk of death from cirrhosis and liver cancer. WHO estimated 257 million people are living with hepatitis B virus (HBV) infection and in 2015 alone HBV resulted in to 887,000 deaths globally. We determined the prevalence and associated factors of hepatitis B virus infection among Antenatal Care (ANC) attendees in Gamawa Local Government Area, Bauchi State. Methods: We conducted a descriptive cross-sectional, health facility-based study between March and April 2018. We used systematic random sampling technique to recruit 210 pregnant women aged 15-49 years. With a structured questionnaire, we interviewed the respondents and collected blood sample to test for hepatitis B surface antigen. We calculated frequencies, means, proportions, and tested for associations using Epi Info 7.2 and Microsoft Excel. Results: The mean age of respondents was 24.5 ± 6.0 years; 53.3% of whom were younger than 25 years. All were married, 87.1% had no formal education and up to 90.5% were employed. Overall, 6.7% tested positive for HBsAg; women aged ≥35 years had the highest prevalence (10.5%). None with tertiary education tested positive and women married before 18 years had 6.5% prevalence. Conclusions: The prevalence of HBsAg among pregnant women in Gamawa LGA was 6.7% which is quite lower than the national prevalence reported. We recommended improved surveillance of HBV infection and screening of women attending ANC.

ObjectivesThis study describes the burden of the hepatitis B, C and HIV co-infections and assesses associated risk factors.SettingThis analysis used data from a viral hepatitis screening campaign conducted in six districts in Rwanda from April to May 2019. Ten health centres per district were selected according to population size and distance.ParticipantsThe campaign collected information from 156 499 participants (51 496 males and 104 953 females) on sociodemographic, clinical and behavioural characteristics. People who were not Rwandan by nationality or under 15 years old were excluded.Primary and secondary outcomesThe outcomes of interest included chronic hepatitis C virus (HCV) infection, chronic hepatitis B virus (HBV) infection, HIV infection, co-infection HIV/HBV, co-infection HIV/HCV, co-infection HBV/HCV and co-infection HCV/HBV/HIV. Multivariable logistic regressions were used to assess factors associated with HBV, HCV and HIV, mono and co-infections.ResultsOf 156 499 individuals screened, 3465 (2.2%) were hepatitis B surface antigen positive and 83% (2872/3465) of them had detectable HBV desoxy-nucleic acid (HBV DNA). A total of 4382 (2.8%) individuals were positive for antibody-HCV (anti-HCV) and 3163 (72.2%) had detectable HCV ribo-nucleic acid (RNA). Overall, 36 (0.02%) had HBV/HCV co-infection, 153 (0.1%) HBV/HIV co-infection, 238 (0.15%) HCV/HIV co-infection and 3 (0.002%) had triple infection. Scarification or receiving an operation from traditional healer was associated with all infections. Healthcare risk factors—history of surgery or transfusion—were associated with higher likelihood of HIV infection with OR 1.42 (95% CI 1.21 to 1.66) and OR 1.48 (1.29 to 1.70), respectively, while history of physical traumatic assault was associated with a higher likelihood of HIV and HBV/HIV co-infections with OR 1.69 (95% CI 1.51 to 1.88) and OR 1.82 (1.08 to 3.05), respectively.ConclusionsOverall, mono-infections were common and there were differences in significant risk factors associated with various infections. These findings highlight the magnitude of co-infections and differences in underlying risk factors that are important for designing prevention and care programmes.

Hepatitis B virus (HBV) is a major public health problem globally and accounts for about one million deaths worldwide annually. This study determined the seroprevalence, distribution of HBV infection, and factors associated with the infection amongst patients attending selected hospitals in Niger State. A total of 500 blood samples were collected from five selected hospitals in Niger state. The samples were screened using Hepatitis B Surface Antigen (HBsAg) test kit for the qualitative detection of Hepatitis B Surface Antigen in serum. Prevalence of Hepatitis B infection was 13.0% cumulatively in the study area. Female participants had a higher prevalence (6.8%) of HBsAg infection compared to their male counterparts with 6.2%. Participants within the 41- 50 years’ age group recorded a higher rate of infection (5.2%), while those ≥ 50 years had a lower prevalence of (2.3%). The civil servants had a higher percentage prevalence of 6.4% followed by housewives and the least was observed with participants who are students. Patients without a history of blood transfusion recorded a higher percentage prevalence (7.8%) compared to those with a history of blood transfusion (5.2%). The results reveal that participants with polygamous family types recorded a higher prevalence of HBV infection (11.4%) compared to those belonging to the monogamous type (1.6%). The results obtained from this study suggest that HBV is in circulation in the study areas; thus necessitating more awareness campaigns among the general population about HBV and its modes of transmission and associated risk factors

Objectives. To estimate race/ethnicity-specific prevalence of hepatitis B surface antigen (HBsAg) in pregnant urban women and to evaluate factors associated with maternal HBsAg testing. Methods. A multicenter, retrospective chart review was conducted of a racially/ethnically stratified random sample of maternal/infant charts of 10 523 women who gave birth to live infants during 1990–1993 in 4 urban areas in the United States. Data were collected on multiple variables, including demographic variables, HBsAg test dates and results, prenatal care type, and amount and source of payment. Results. HBsAg prevalence among white non-Hispanics was 0.60% (95% confidence interval [CI]: 0.22–0.98), black non-Hispanics 0.97% (95% CI: 0.48–1.47), Hispanics 0.14% (95% CI: 0.01–0.26), and Asians 5.79% (95% CI: 4.42–7.16). HBsAg testing rates increased from 56.6% in 1990 to 78.2% in 1993. Factors associated with not being tested varied by urban area, but in the combined area model, they were having no or private prenatal care (odds ratios: 18.75 and 5.07, respectively) and being black (odds ratios: 2.08). Only 20.9% (95% CI: 19.1%–22.8%) of those not tested prenatally were tested at delivery. The expected number of infants born to HBsAg-positive study-area women was 3327 using study prevalence rates, compared with 1761 using national rates. Conclusions. To help ensure that all urban infants who are born to HBsAg-positive women receive appropriate prophylaxis, health officials in urban areas should use urban-area prevalence rates to ascertain completeness of reporting maternal HBsAg positivity. Needed steps to increase maternal HBsAg testing rates include ensuring that more pregnant women receive prenatal care, promoting testing by private providers, educating providers about testing in all racial and ethnic groups, and reminding providers to test at delivery those women not tested prenatally.
