Determine seroprevalence and associated risk factors of HBV infection among pregnant women and it relationship with blood transfusion at Hargeisa Group Hospital, Hargeisa, Somaliland

Background: In Republic of Chad, the seroprevalence of HIV among antenatal pregnant women is known as decreasing over years meanwhile the epidemiological data among pregnant women for hepatitis B virus are scarce. The co-infection HIV/HBV increases the risk of mother to child transmission of both viruses. This study aimed to determine the rate of HIV, HBV co-infection and to identify the associated risk factors among pregnant women attending Guelendeng health district (GHD). Methods: A cross-sectional and descriptive study was conducted from March to May 2019 among pregnant women attending GHD. The questionnaire included demographics, AIDS and HBV knowledge, behavior factors and history of blood transfusion. Blood samples were obtained and tested serologically for HIV and HBV. The study of associations between exposure and outcome variables was sought with the odds ratio (OR), expressed with 95% confidence interval. Tests were performed using Epi info 7.0 with p<0.05 considered as significant. Results: Out of 200 enrolled pregnant women, the median age was 25years old with interquartile range from 20.5 to 30 years old. The seroprevalence of HIV, HBV and the co-infection HIV/HBV were 4.5% (95% CI: 2.1%-8.4%; 9/200), 13% (95% CI: 8.7%-18.5%; 26/200) and 2% (95 % IC: 0.6%-5%; 4/200) respectively. The antenatal age was associated to HBV infection (p=0.04) unlike HIV infection (p=0.4) and HIV/HBV co-infection (p=0.52). Women aged more than 29 years were most affected. Bivariate analysis identified that the non-use of condom (OR 7.79, 95% CI: 1.9-32.6, p=0.004) and blood transfusion history (OR 17.9, 95% CI: 2.6-124.8, p=0.01) were associated risk factors of contracting HIV. Conclusion: The seroprevalence of HIV and HBV remains high among pregnant women attending antenatal ward in Guelendeng Health District with associated risk factors such as age, blood transfusion and the non-use of condom with new sexual partners.

Background & aim Hepatitis B and C infections are global issues that are associated with a massive financial burden in developing countries where vertical transmission is the major mode and remains high. This cross-sectional study was designed to investigate the seroepidemiology and associated risk factors of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among 375 pregnant women attending antenatal care health facilities at Bacha Khan Medical Complex (BKMC) Shahmansoor and District Head Quarter (DHQ) Hospital Swabi, Khyber Pakhtunkhwa, Pakistan. Methodology From a total of 375 pregnant women selected using systematic random sampling from both hospitals, 10 ml of blood samples were collected and alienated serum was examined for indicators identification through the Immuno-Chromatographic Test (ICT) and 3rd Generation Enzyme-Linked Immunosorbent Assay (ELISA). A pre-structured questionnaire was used to collect the socio-demographic data and possible risk factors. The data was analyzed via SPSS 23.0 statistical software. A chi-square analysis was performed to determine the association between variables. P-value < 0.05 was set statistically significant. Results The overall frequency of HBV and HCV among 375 pregnant women involved in the study was 3.7% and 2.1% respectively. None of the pregnant women were co-infected with HBV and HCV. Dental extraction (P = 0.001) and blood transfusion (P = 0.0005) were significantly allied with HBV infection while surgical procedure (P = 0.0001) was significantly associated with HCV infection. Moreover the sociodemographic characteristics: residential status (P = 0.017) and educational level (P = 0.048) were found significant risk factors of HBsAg and maternal age (P = 0.033) of anti-HCV, respectively. Conclusion & recommendation HBV and HCV infections are intermediary endemic in the study area. A higher prevalence of HBV was detected among pregnant mothers with a history of dental extraction, history of blood transfusion, resident to the urban area and low educational level. The age and surgical procedures were the potential risk factors found significantly associated with HCV positivity among pregnant mothers in our setup. Future negotiations to control vertical transmission should include routine antenatal screening for these infections early in pregnancy and the requirement of efficient preventive tools including the birth dose of the hepatitis B vaccine in combination with hepatitis B immune globulins to the neonate.

BACKGROUND: Vertical transmission is also mode of transmission of HBV, HCV and HIV. Viral infections may cause abortion, ectopic pregnancies and HBV, HCV also causes hepatitis, cirrhosis. ‘Janani Sureksha Yojana’ (safe motherhood program) is a scheme in which pregnant women are benefited if they deliver in government medical facility. Antenatal screening for HBV, HCV and HIV should be done so as to provide appropriate antiviral therapy. The aim of study was to detect the frequency of HBsAg, HCV antibody, HIV antibody and their correlation with risk factors.METHODS: Present study was conducted in central laboratory of Rural Institute of Medical Science and Research Saifai, Etawah (Uttar Pradesh) on pregnant women from 1 January to 31 December 2014.RESULTS: Out of 7867 women, 2.07% were positive for HBsAg, 0.43% and 0.13% for HCV antibody and HIV antibody, respectively. The age group with maximum seropositivity was in 21-30 year (76.44%) and parity with maximum seropositivity was 3-4 children (42.30%). Seropositivity was high among low socio economic status (77.40%). Among the associated risk factors Obstetric and Gynaecology surgeries (46.15%) and blood transfusion (20%) were prominent. These associated risk factors were found more among HBsAg seropositive females (86.66%) and (84.61%) respectively.CONCLUSIONS: The prevalence of HBsAg positive (2.07%) was more. Obstetric and Gynaecology surgery, blood transfusion were major risk factors. So, screening for HBsAg, HCV antibody, HIV antibody should be mandatory for pregnant women to reduce mortality and morbidity.

AbstractA birth cohort study was conducted in Khan Hoa Province, central Vietnam between 2009 and 2012 to determine the seroprevalence of hepatitis B virus (HBV) in pregnant women and their children, and associated risk factors. We enrolled 1987 pregnant women with their babies at the birth phase, and 12.6% (95% confidence interval [CI]: 11.1–14.0) of mothers were hepatitis B surface antigen (HBsAg)+. At 2-year follow-up phase, 1339 (67.4%) children were enrolled of whom 76.6% completed hepatitis B vaccines (HepB) and 1.9% (95% CI: 1.2–2.7) were HBsAg+. When mothers were hepatitis B e antigen (HBeAg)+, 28.3% of children have got infected even with complete HepB. HBV infection in mothers, hepatitis B surface antibody (anti-HBs antibody) below the seroprotective level in children, and mothers with pre-pregnancy low body mass index were associated with HBV infection in children. Meanwhile, HBV infection in children, older maternal age, no or incomplete doses of HepB, and boys were associated with anti-HBs antibody below the seroprotective level in children. Our birth cohort study determined a low rate of congenital HBV infection and associated risk factors in Vietnam, however further studies are needed to advance prevention including anti-viral therapy in pregnant women at high risk.

Abstract Background: Syphilis and Hepatitis B Virus (HBV) share similar modes of transmission. Their occurrence during pregnancy has an adverse effect both on the fetus and pregnant women. The aim of this study was to determine the seroprevalence and associated risk factors of syphilis and HBV among pregnant women. Methods: A cross-sectional study was undertaken from July to September 2019 in 290 pregnant women at Saint Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia. Gestational and socioeconomic data were collected using a questionnaire. Chromatographic kits were used to detect the presence of Hepatitis B surface antigen (HBsAg) and antibody against syphilis infection from the serum of study participants. Data were analyzed by SPSS version 22. Bivariate and multivariable analysis was employed to identify factors associated with seroprevalence of syphilis and HBV. Variables with a p-value of < 0.05 were considered as cut point to determine a significant association. Results: Seroprevalence of HBV and syphilis infection were found to be 4.5% and 2.4 % respectively. Having multiple sexual partner [AOR=3.99, 95%Cl= 1.20-13.38, p=0.025] was significantly associated with HBV infection. Conclusion: In the study the seroprevalence of HBV and syphilis is moderate; having multiple sexual partners was found to be significantly associated with the prevalence of HBV infection.

Hepatitis B virus (HBV) when transmitted vertically can be severe on neonates and life threatening. Among others, risk factors for HBV include unprotected sex, needle-stick injuries and blood transfusion. The study was conducted to determine the seroprevalence of HBV markers and associated risk factors among one hundred and sixty consenting pregnant women attending some hospitals in Kano, Nigeria. Using enzymelinked immunoassay, sera were screened for HBV sero-markers and structured questionnaires were administered to obtain sociodemographic data and possible predisposing factors to HBV infection. Of the five HBV markers known, participants tested positive for four, which include HBsAg, HBsAb, HBeAb and HBcAb. All were seronegative for HBeAg. Ninety three percent (93.1%) tested positive for at least one HBV marker and 6.9% were seronegative for all markers. Among those that tested positive for HBsAg, 54.5% (p=0.33) were housewives, 36.4% (p=0.53) had only primary school education, 72.7% (p=0.14) were middle-class, none had previous knowledge of HBV infection and its mode of transmission, 54.5% (p=0.14) regularly shares sharp objects, 45.5% (p=0.37) had ear or nose piercing, and 9.1% (p=0.01) regularly shares towel and underwear. A large percentage of the study group had history of the infection while only 1.3% of the subjects were vaccinated. Sociodemographic background of the participants, low vaccination coverage and certain risk factors like the sharing of unsterilized sharp objects seem to aid the moderately high prevalence of HBV in this study. The study also revealed that the risk of mother-to-child HBV transmission is low in the study area and that incomplete vaccination may not confer artificial immunity against HBV infection.
