Routine infectious diseases screening of Sudanese pregnant women has been patchy due to scarcity of healthcare resources and social stigma. We sought to determine the seroprevalence of HIV, hepatitis B, and syphilis among pregnant women attending antenatal care (ANC) at El Obeid Maternity Hospital in western Sudan. We also explored the association between these infections and a set of socio-demographic and maternal variables. Unlinked anonymous testing for HIV-1/2 antibodies, hepatitis B surface antigen, and Treponema pallidum antibodies was performed on residual blood samples collected during routine ANC (August 2016–March 2017). Seroprevalence of HIV was 1.13% (5/444; 95% CI 0.37–2.61%), hepatitis B 2.93% (13/444; 95% CI 1.57–4.95%), and syphilis 7.43% (33/444; 95% CI 5.17–10.28%). On bivariate analysis, there were no statistically significant associations between hepatitis B, syphilis, or a composite outcome including any of the three infections and age, stage of pregnancy, gravidity, parity, previous mode of delivery, history of blood transfusion, or husband polygamy. Urgent action is needed to scale up routine maternal screening for HIV, hepatitis B, and syphilis on an opt-out basis. Further research into the socio-demographic and behavioural determinants of these infections as well as their clinical outcomes is needed.

Beginning in 1982 all pregnant women undergoing prenatal routine blood analysis in three large city hospitals and one large rural area were tested for hepatitis B surface antigen (HBsAg). Infants of all HBsAg-positive mothers received hepatitis B immunoglobulin (HBIg), 0.5 mL/kg of body weight within two hours of birth and, after randomization, 10 µg of hepatitis B vaccine either at 0, 1, 2, and 11 months of age (schedule A) or at 3, 4, 5, and 11 months of age (schedule B). A second injection of HBIg (1 mL) was given to infants on schedule B at 3 months of age. Blood samples were obtained at 3, 6, 11, 12, 24, and 36 months. In a two-year period, 28,412 pregnant women were tested for HBsAg; screening efficiency varied between 85% and 98%. The overall prevalence of HBsAg was 0.8%, with a marked variation between urban centers (2.2%) and the rural area (0.3%). Vaccinations were received by 180 of 193 infants of HBsAg-positive mothers (90 on schedule A and 90 on schedule B). Concentrations of hepatitis B surface antibody less than 10 IU/L were observed in nine instances in five children from group A and in seven instances in six children from group B. Four hepatitis B viral infections (two HBsAg carriers, two who underwent antihepatitis B core seroconversions) were recorded in group A v one infection (antihepatitis B core seroconversion) in group B. The protective efficacy of the program (screening plus passive immunization and delayed vaccination) was 94%. The estimated cost of preventing one case of hepatitis B infection in neonates was $3,000 (US currency). It is concluded that screening all pregnant women for HBsAg can be introduced effectively at reasonable costs in a country with a low prevalence of HBsAg and a high proportion of home deliveries. Delayed active vaccination starting at 3 months of age may be an effective and, for reasons of high compliance and low cost, attractive alternative to early active vaccination.

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.

The aim of the study was to identify the prevalence of hepatitis B and C seropositivity in pregnant women attended in a public maternity hospital located in Catalao-GO from 2005 to 2009. Descriptive, exploratory study conducted through patients` hospital records. For data analysis, we used SPSS version 18.0. The confidence interval (CI) was calculated using the Person χ² test, considering a significance level of 5% (p <0.05). The prevalence of HBV was 5.64% and HCV 0.098%, predominantly in young pregnant women aged between 20 and 30 years old, single and in their first pregnancy.

Background: Pregnant women with Hepatitis B virus HBV represent a major reservoir of the virus in the community. Data regarding the prevalence of HBV in pregnant women and maternal transmission of the virus in Libya are lacking. Methodology: Hepatitis blood samples from 1,500 pregnant women and 1,500 cord blood samples of their neonates delivered at Tripoli Medical Center, Tripoli, were tested for HBsAg by ELISA technique. HBsAg-positive samples were also tested for HBeAg. Results: HBsAg was detected in 1.5% (23/1,500) pregnant women and in 0.9% (14/1,500) neonates. Although HBsAg was detected at higher rate in pregnant women aged > 25 years [1.8% (22/1,235)] than in pregnant women aged < 25 years [0.4% (1/265)], the difference was not statistically significant (P > 0.05). All HBsAg-positive neonates were born to HBsAg-positive mothers with a rate of maternal transmission at 60.9% (14/23). HBeAg was detected in 21.7% (5/23) and in 7.1% (1/14) of HBsAg-positive pregnant women and neonates, respectively. Conclusions: Because of the high risk of developing chronic HBV infection at birth among infants born to HBsAg-positive mothers, administration of HBIG in combination with hepatitis B vaccine as post-exposure prophylaxis for such infants is of paramount importance. In addition, universal HBsAg screening of all pregnant women will greatly assist in reducing the maternal transmission of HBV in the country.
