Hepatitis B and Asymptomatic Malaria Infection among Pregnant Women in a Semiurban Community of North-Central Nigeria

Background. The overlap of malaria and Hepatitis B Virus (HBV) infections present a major threat to public health throughout endemic countries of tropical and sub-Saharan Africa. There is a paucity of data on the prevalence and associated factors of malaria and HBV infections among pregnant women in Ejule, a semiurban area of Nigeria. Therefore, the current study was designed to assess the seroprevalence of malaria and HBV among pregnant women attending antenatal clinics in Ejule Metropolis. Materials and Methods. In a hospital-based cross-sectional study, blood samples collected from 200 apparently healthy pregnant women at the Ilemona Clinic were screened for Plasmodium falciparum (P. falciparum) and HBsAg using histidine-rich protein 2 (HRP2) and hepatitis B surface antigen (HBsAg) rapid diagnostic tests (RDTs), respectively. Relevant sociodemographic and putative risk factor information was obtained with structured questionnaires. Results. The prevalence of the infections was 44 (22%), 5 (2.5%), and 1 (0.5%) for P. falciparum monoinfection and HBV monoinfection and coinfection, respectively. Single and concurrent infections peaked at ages 31–40 years but decreased with older ages. High P. falciparum, 31 (59.62%), and HBV 2 (3.85%) infection were observed among those without formal education. Contrary to ages, occupation, and knowledge of infection, malaria parasitemia differed significantly with lower educational qualification ( p ≤ 0.001 ), being single ( p = 0.001 ), and inconsistent use of insecticide-treated bed nets (ITNs) ( p = 0.04 , OR = 5, CI: 0.10–0.47). History of blood donation (OR = 5, p = 0.04 , CI: 1.10–32.80) and multiple sex partners (OR = 11.9, p = 0.01 , CI: 0.01–0.93) were found to be significantly associated with hepatitis B surface antigenemia rate during pregnancy. No evidence of HBV infection was observed in women with a history of HBV vaccination. Conclusions. Malaria is still highly prevalent among pregnant women due to high illiteracy and noncompliance to using ITNs. Therefore, routine screening and educating pregnant mothers are crucial in eliminating malaria in endemic settings. The low rate of hepatitis B and coinfection with malaria shows that further improvement in HBV vaccination could considerably reduce the disease burden among pregnant women.

Abstract Background The hepatitis B virus (HBV) status of pregnant women affects HBV vaccine failure in their offspring. This study is aimed to investigate the impact of the universal infant HBV vaccination program on the long-term hepatitis B surface antigen (HBsAg) rate in pregnant women. Methods Using the National Immunization Information System, we examined a 32-year period of cross-sectional data on a maternal HBsAg and hepatitis B e antigen (HBeAg) screening program launched in July 1984. An age-period-cohort model analysis of 940 180 pregnant women screened for July 1996–June 1997 and the years 2001, 2006, 2011, and 2016 was applied. Results The annual HBsAg- and HBeAg-seropositive rates decreased from 13.4% and 6.4%, respectively, for the period 1984–1985 to 5.9% and 1.0% in 2016 (P for both trends < .0001). Pregnant women with birth years after July 1986 (the HBV vaccination cohort) had the lowest relative risk (0.27 [95% confidence interval, .26–.28]) of HBsAg positivity compared with birth years before June 1984. Conclusions The birth cohort effect in relation to the universal infant HBV immunization program has effectively reduced the HBV carrier rate in pregnant women and the burden of perinatal HBV infection on the next generation.

Background & Objective: Transfusion associated hepatitis B virus (TAHBV) infection continues to be a major problem despite mandatory screening for hepatitis B surface antigen (HBsAg). This is because HBsAg is not detected during the window period of the infection. This study was designed to assess the frequency of anti HBc antibody among HBsAg negative donor and also to determine the demographic profile of healthy blood donors.Material & Method: This cross sectional observational study was carried out in the Department of Transfusion Medicine, BSMMU, Dhaka during the period of May 2014 to April 2015. A total number of 100 consecutive healthy blood donors who were clinically and physically healthy and serologically found to be free from HBsAg, HCV and HIV by rapid chromographic test were included in this study.Results: Within the 100 patients among them history of jaundice was found in 17(17.0%). There all (100.0%) subjects had negative HBsAg and 14(14.0%) subjects had positive anti HBc-Ab. Anti HBc-Ab was statistically significant (p<0.001) in Z-test.Conclusion: This study was undertaken to assess the prevalence of anti HBc antibody among healthy blood donors with HBsAg negative in rapid chromatography method. The prevalence of anti HBc antibody was about 14 (14.0%) among 100 HBsAg negative blood donors. History of blood donation was found in almost two third 65 (65.0%). So, anti HBc antibody screening is an useful tool for estimating the risk of transfusion transmitted HBV infection.Bangladesh Journal of Medical Science Vol.15(1) 2016 p.66-69

Detailed knowledge about hepatitis B virus (HBV) vaccination coverage and timeliness for sub-Saharan Africa is scarce. We used data from a community-based cross-sectional survey conducted in 2018–2019 in the area of Niakhar, Senegal, to estimate coverage, timeliness, and factors associated with non-adherence to the World Health Organisation-recommended vaccination schedules in children born in 2016 (year of the birth dose (BD) introduction in Senegal) and 2017–2018. Vaccination status was assessed from vaccination cards, surveillance data, and healthcare post vaccination records. Among 241 children with available data, for 2016 and 2017–2018, respectively, 31.0% and 66.8% received the BD within 24 h of birth (BD schedule), and 24.3% and 53.7% received the BD plus at least two pentavalent vaccine doses within the recommended timeframes (three-dose schedule). In logistic regression models, home birth, dry season birth, and birth in 2016 were all associated with non-adherence to the recommended BD and three-dose schedules. Living over three kilometres from the nearest healthcare post, being the firstborn, and living in an agriculturally poorer household were only associated with non-adherence to the three-dose schedule. The substantial proportion of children not vaccinated according to recommended schedules highlights the importance of considering vaccination timeliness when evaluating vaccination programme effectiveness. Outreach vaccination activities and incentives to bring children born at home to healthcare facilities within 24 h of birth, must be strengthened to improve timely HBV vaccination.

Introduction. Hepatitis virus infection is a major public health burden and silent killer disease in sub-Saharan Africa, including Ethiopia. Therefore, this study aimed to investigate the prevalence of hepatitis B and C viruses and associated factors among pregnant women attending an antenatal clinic in three tertiary hospitals in Amhara National Regional State, Ethiopia. Methods. A cross-sectional study was conducted among 1121 pregnant women. Data on sociodemographic and associated factors were collected using a structured questionnaire. Serum samples were tested for hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus antibody (anti-HCV) using ELISA. SPSS version 20 was used for data analysis, and a multivariable logistic regression analysis was used to assess the relationship between factors associated with hepatitis B virus and hepatitis virus C infection. Results. A total of 1121 pregnant women were included in the study. The mean age of study participants was 27.2 ± 4.8 yrs. The majority of pregnant women (895 (79.8%)) were from urban areas. The overall seroprevalence of HBsAg and anti-HCV antibody was 52 (4.6%) and 18 (1.6%), respectively. The coinfection rate of HBV/HCV was 1.4% (1/69). Ten (19.2%) of HBV positive cases were coinfected with HIV. There were no coinfections of HCV and HIV. Interestingly, pregnant women with a history of multiple sexual partners (AOR = 3.2, 95% CI, 1.7–7.6), blood transfusion (AOR = 7.6, 95% CI, 2.9–16.9), family history of HBV (AOR = 3.5, 95% CI, 1.7–7.6), being HIV-positive (AOR = 2.5, 95% CI, 1–5.9), and tattooing (AOR = 2, 95% CI, 1–3.8) were significant predictors of HBV infection. Similarly, young age (17–25 yrs) (AOR = 3.2, 95% CI, 1.8–8.6) and no educational background (AOR = 5, 95 CI, 1.7–14.8) were significant predictors of HCV infection. Conclusions. Hepatitis B and C viruses’ infection was intermediate among pregnant women; some risk factors were significantly associated with the majority of cases. Infants born from these infected mothers are at risk of infection. This calls for screening and integration of HBV prevention of mother-to-child transmission (PMTCT) into HIV. Thus, the provision of health education on hepatitis B and C viruses’ transmission, vaccination, and screening of all pregnant women routinely are essential for the prevention of these viruses.

Background: Hepatitis B Virus (HBV) infection has reached pandemic proportions all over the world with areas of highest prevalence being the sub- Saharan Africa and Southeast Asia. Most deaths related to HBV are due to complications from chronic infection. Acquisition of infection at a younger age is the most important predictor of chronicity. Eradication of HBV is an important but difficult tasks facing public health. HB immunization is the single most important factor in hepatitis B control and was commenced in 2004 in Nigeria.Objectives: To determine the prevalence of Hepatitis B surface antigen (HBsAg) among children in the era of HB immunization, the risk factors of transmission and knowledge of mothers about their HB status.Methods: A cross sectional study carried out on one hundred and forty children aged 18 months to 15 years at the children outpatient clinic (CHOP) of the University of Nigeria Teaching Hospital, Ituku. Hepatitis B surface antigen (HBsAg) was determined using Determine Test Kits and a structured interviewer administered questionnaire administered.Results: Six were positive for HBsAg, giving a prevalence rate of 4.3%. HBsAg was least prevalent among children 1-5 years (2%). None of the children ≤ 5 years who received HB vaccination was positive for HBsAg though one child > 5 years who received the vaccine was positive. Sharing of toothbrushes among siblings was found to be a significantly associated risk factor. Only 6.4% of mothers knew their hepatitis B status.Conclusion: There is a gradual fall in the prevalence of HBsAg in our environment due to HB immunization. Sharing of toothbrushes may be a potent means of transmission of HBV infection.Keywords: HBV, Prevalence, Children, Transmission, HB immunization

Abstract Introduction Within sub-Saharan Africa (SSA), the burden of chronic hepatitis B (HBV) is unacceptably high in several countries including Uganda. Elimination of HBV in the context of inadequate resources and several competing health issues, faces challenges including limited data on disease burden in important population sub-groups. In order to optimize available resources, reliable data on HBV among pregnant women is useful to guide policies on prevention. This study estimated HBV prevalence and related factors among pregnant women in Central and West Nile regions of Uganda Methods Using a two-stage sampling approach, we selected a random sample of 310 pregnant women, 18 years or older from public health facility antenatal clinics in central and west Nile, North-western Uganda. Consenting women were interviewed to obtain data on HBV vaccination status, HIV status, selected sexual and lifestyle factors and socio-demographic information. In addition, they underwent phlebotomy to obtain blood for testing for hepatitis B surface antigen, (HBsAg) antibodies to the surface antigen (anti-HBs), and antibodies to the core (anti-HBc), as indicators of chronic infection, prior exposure, and susceptibility (anti-HBs <10 mIU /mL), respectively. Results Out of 310 women, prevalence of chronic HBV infection was 6.2%. Prevalence in the West Nile region was notably higher than in the Central region (11.0% vs. 1.3%), p<0.001. In both regions, majority of pregnant women (61% West Nile region, 76% Central region) were still susceptible to HBV. Overall, proportion who had been tested for HBV and those who reported having been vaccinated was only 5.8% and 11.3% respectively. Conclusion Our findings reveal the burden of HBV in Ugandan pregnant women is still high, with marked regional differences in disease prevalence, and poor levels of HBV testing and vaccination. These data suggest that HBV prevention programs and policies in resource-limited settings like Uganda may need to consider the differential HBV prevalence, as optimizing HBV prevention services in higher prevalence regions may provide greater impact and thereby align with the WHO recommendation on HBV elimination strategy in SSA.

Blood safety remains a challenge to many countries in sub-Saharan Africa including Ghana due to poorly planned blood donation exercises in the various communities. Blood and its products usual-ly come from two main sources; voluntary non-remunerated donors (VNRD) and family replace-ment donors (FRD). In Ghana, and in many developing countries, FRDs seem to be the major source of blood supply whilst in developed countries VNRDs are the major source. This study de-termined and compared the prevalence of four transfusion transmissible infections (TTIs); HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema palladium (TP) among FRDs and VNRDs at the Komfo Anokye Teaching Hospital to compare the safety of blood from these two groups. This cross-sectional study was undertaken at the transfusion medicine unit (TMU) of the Komfo Anokye Teaching Hospital between March and May 2014. A total of 400 blood donors (200 FRDs and 200 VNRDs) were enrolled in this study after obtaining written informed consent. Blood samples from each of the donors were then tested for HIV, hepatitis B and C, and syphilis using rapid test kits. ABO and Rhesus blood groups were also determined for all the samples. Prev-alence of TTIs was higher among FRDs (23.5%) than in VNRDs (3.5%) with males (47) been more infected than females (7). Age group 21- 30 years was the most infected, followed by age groups 31- 40 years, 11- 20 years, 41- 50 years and 51- 60 years respectively. FRDs among the younger age group, 17- 30 years, were also more infected than their VNRD counterparts. Repeat blood donors among the VNRD group, were found to be safer than their first-time counterparts. Overall, TTIs were significantly higher in the FRD group than in the VNRD group. The prevalence rates of all the infections tested were higher in the FRD group compared to the VNRD group. FRDs were the higher risk population for TTIs in comparison to VNRDs. VNRDs should therefore be encouraged to donate blood regularly.Keywords: Transfusion Transmissible Infections, HBsAg, HCV, HIV, Treponema pallidum

Abstract Background Hepatitis virus infection is a major public health burden and silent killer disease in sub-Saharan Africa, including Ethiopia. Despite the recommendations of the World Health Organization, screening for hepatitis B virus (HBV) and hepatitis C virus (HCV) in pregnant women is not done routinely in public health institutions. Therefore, this study aimed to determine the burden of HBV and HCV and its associated factors among pregnant women in the Amhara region, Ethiopia. Methods A total of 1121 pregnant women were enrolled in the study. Data on sociodemographic and associated factors were collected using a structured questionnaire. Blood was collected from the pregnant women, and serum samples were tested for HBsAg and anti-hepatitis C virus antibody (anti-HCV) using ELISA. The status of HIV-infected pregnant women was collected from the records of their charts. SPSS version 20 was used for data analysis, and a binary logistic regression model was used to assess the relationship between factors associated with HBV and HCV infection. Results The seroprevalence of HBsAg and anti-HCV antibody were 4.6% and 1.6, respectively. The co-infection rate of HBV/HCV was 1.4% (1/69). Ten out of 52 HBV positive cases (19.2%) were co-infected with HIV. Only 20 (1.8%) pregnant women had the HBV vaccine. Interestingly, pregnant women with a history of multiple sexual partners (AOR = 3.2,95% CI,1.7–7.6), blood transfusion (AOR = 7.6,95% CI,2.9–16.9), family history of HBV (AOR = 3.5, 95% CI,1.7–7.6), being HIV-positive (AOR = 2.5, 95% CI,1-5.9), and tattooing (AOR = 2, 95% CI, 1-3.8) were significant predictors of HBV infection. Conclusions HBV and HCV infections were intermediate among pregnant women; risk factors were responsible for the majority of cases. Infants born from these infected mothers are at risk of infection. This calls for integration of HBV prevention into the PMTC of HIV. Thus, the provision of health education on HBV and HCV transmission, vaccination, and screening of all pregnant women routinely is essential for PMTCT.

Abstract Background; Hepatitis B virus (HBV) is the world’s most common and highly contagious liver infection. Its transmission methods are: mother to child, via open wounds, sexual contact, blood transfusion and other blood contact related activities. Prevalence of HBV among pregnant women in Africa ranges from 3.67 - 16.5% and in Ethiopia 2.4 to 8.4%. Hepatitis B infection leads to high morbidity and mortality for mother as well as for their infants due to the vertical transmission. Hence assessing the prevalence and associated factors of Hepatitis B Virus infection is a priority. Methodology : An institution based cross sectional study was conducted with a total of 194 of pregnant women attending antenatal care at Agena health center from May 1-30/2019. Frequency analysis and Logistic regression test was used to determine the associated factors associated with Hepatitis B virus by using SPSS version 25. Results: The prevalence of HBV in Agena health center among pregnant women were 4.1% and it was associated with marital status, history of hospital admission and history of abortion. Conclusion : The prevalence of HBV in Agena health center among pregnant women was intermediate. Since routine screening and immunization of all pregnant women is mandatory.
