Seroprevalence of hepatitis B virus among pregnant women attending Antenatal care in Dilla University Referral Hospital Gedio Zone, Ethiopia; health facility based cross-sectional study

Epidemiology of hepatitis B virus infection among pregnant women in Africa: a systematic review and meta-analysis

BACKGROUND

Although hepatitis B infection is highly endemic in Africa, information on its epidemiology among pregnant women in the region is limited. Therefore, this systematic review provided up-to-date information on the epidemiology of hepatitis B virus (HBsAg) infection among pregnant women in Africa.

METHODS

A systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews. The Web of Science, Scopus, PubMed, Google Scholar, and African journals online were searched to identify relevant studies published between January 1, 2015, and May 21, 2024, on hepatitis B virus infection in pregnant women living in Africa. The Joanna Briggs Institute tool was used to assess the methodological qualities of the included studies. The random effects model was used to estimate the pooled prevalence of HBV infection. I2 assessed the amount of heterogeneity. Publication bias was assessed using Egger's test and a funnel plot.

RESULTS

We included 91 studies from 28 African countries. The pooled prevalence of hepatitis B infection among pregnant women in Africa was 5.89% (95% CI: 5.26-6.51%), with significant heterogeneity between studies (I2 = 97.71%, p < 0.001). Family history of hepatitis B virus infection (AOR = 2.72, 95%CI: 1.53-3.9), multiple sexual partners (AOR = 2.17, 95%CI: 1.3-3.04), and sharing sharp materials were risk factors for hepatitis B infection.

CONCLUSION

An intermediate endemic level of hepatitis B virus infection (2-7%) was observed among pregnant women in Africa. To prevent disease transmission, interventions should focus on pregnant women with a family history of hepatitis B infection, multiple sexual partners, and sharing sharp materials.

Seroprevalence of hepatitis B virus and hepatitis C virus infection among pregnant women attending antenatal care at Guhala Primary Hospital, Northwestern Ethiopia

BACKGROUND

Hepatitis B virus (HBV) and Hepatitis C Virus (HCV) infections are global issues that disproportionately affect developing countries. Pregnancy-related HBV and HCV infections are associated with a high risk of vertical transmission and complications for the mother as well as the newborn. Therefore, this study aims to determine the seroprevalence of hepatitis B virus and hepatitis C virus infection among pregnant women attending antenatal care at Guhala Primary Hospital, Northwestern Ethiopia.

METHODS

A hospital-based retrospective study was conducted from July to September 2022 on HBV and HCV registered books from September 1, 2017, to August 30, 2019, for a year. The presence of HBsAg and anti-HCV in serum was detected using the One Step Cassette Style HBsAg and anti-HCV antibody test kit. Data were analyzed using SPSS version 26 software.

RESULTS

In this study, a total of 2252 participants for HBsAg and 538 participants for ant-HCV rapid tests of records in the laboratory logbook were included. The mean age of the study participants was 25.6years (± 5.8SD). The overall prevalence of HBsAg and anti-HCV was 6.0% (134/2252) and 2.4% (13/538), respectively. There were 0.4% (2/538) coinfection results between HBV and HCV among pregnant women.

CONCLUSION AND RECOMMENDATION

In this study, intermediate seroprevalence of HBV and HCV infection was detected among pregnant women attending antenatal care. The Hepatitis B virus was predominantly higher among pregnant women aged between 25 and 34 years. To manage and stop the potential vertical transmission of these viral agents during the early stages of pregnancy, routine prenatal testing for HBV and HCV infections should be taken into consideration.

Prevalence of hepatitis B virus infection among pregnant women in Africa: A systematic review and meta-analysis

INTRODUCTION

Africa exhibits a considerably high prevalence of the hepatitis B virus among pregnant women. Furthermore, there is a discernible lack of a well-established surveillance system to adequately monitor and comprehend the epidemiology of the hepatitis B virus, particularly among pregnant women. The eradication efforts of the virus in Africa have been impeded by the significant disease burden in the region, and there is a lack of evidence regarding the pooled prevalence of the hepatitis B virus in Africa. Consequently, this systematic review and meta-analysis aims to determine the prevalence of hepatitis B virus infection among pregnant women in Africa.

METHODS

We conducted a systematic literature search using reputable databases such as PubMed, Advanced Google Scholar, Scopus, and the Cochrane Library. The search spanned from July 2013 to July 2023 and included all relevant articles published within this period. To identify potentially eligible articles, we conducted a comprehensive manual review of the reference lists of the identified studies. Our review encompassed articles from the African Journal Online. The analysis focused on observational studies published in peer-reviewed journals that reported the prevalence of hepatitis B surface antigen-positive testing among pregnant women. We utilized the Newcastle-Ottawa critical appraisal checklist to assess the methodological quality of each paper. Finally, a meta-analysis was conducted using a random-effects model.

RESULTS

Out of the 774 studies identified, 31 studies involving 33,967 pregnant women were selected for the meta-analysis. According to the random-effects model, the combined prevalence of hepatitis B virus among pregnant women was 6.77% [95% CI: 5.72, 7.83]. The I2 statistic was calculated to be 95.57% (p = 0.00), indicating significant heterogeneity among the studies. The high I2 value of 95.57% suggests a substantial degree of heterogeneity. A subgroup meta-analysis revealed that factors such as time-dependent bias, sample size dependence, or individual variation among study participants contributed to this heterogeneity (p-difference < 0.05).

CONCLUSION

According to the findings of this study, the pooled prevalence of hepatitis B infection among pregnant women in Africa was found to be intermediate-high. It is recommended that policymakers implement hepatitis B virus immunization programs targeting pregnant women and their new-born babies at higher risk of exposure.

Prevalence of Hepatitis B virus infection and its determinants among pregnant women in East Africa: Systematic review and Meta-analysis

INTRODUCTION

Hepatitis B virus (HBV) is one of the major public health problems globally and needs an urgent response. It is one of the most responsible causes of mortality among the five hepatitis viruses, and it affects almost every class of individuals. Different studies were conducted on the prevalence of HBV among pregnant women in East African countries, but none of them showed the pooled prevalence of HBV among the pregnant women. Thus, the main objective of this study was to determine the pooled prevalence and its determinants among pregnant women in East Africa.

METHODS

We searched studies using PubMed, Scopus, Embase, ScienceDirect, Google Scholar and grey literature that were published between January 01/2020 to January 30/2024. The studies were assessed using the Newcastle Ottawa Scale (NOS) quality assessment scale. The random-effect (DerSimonian) model was used to determine the pooled prevalence and associated factors of HBV among pregnant women. Heterogeneity were assessed by I2 statistic, sub-group analysis, and sensitivity analysis. Publication bias was assessed by Egger test, and the analysis was done using STATA version 17.

RESULT

A total of 45 studies with 35639 pregnant women were included in this systematic review and meta-analysis. The overall pooled prevalence of HBV among pregnant women in East Africa was 6.0% (95% CI: 6.0%-7.0%, I2 = 89.7%). The highest prevalence of 8% ((95% CI: 6%, 10%), I2 = 91.08%) was seen in 2021, and the lowest prevalence 5% ((95% CI: 4%, 6%) I2 = 52.52%) was observed in 2022. A pooled meta-analysis showed that history of surgical procedure (OR = 2.14 (95% CI: 1.27, 3.61)), having multiple sexual partners (OR = 3.87 (95% CI: 2.52, 5.95), history of body tattooing (OR = 2.55 (95% CI: 1.62, 4.01)), history of tooth extraction (OR = 2.09 (95% CI: 1.29, 3.39)), abortion history(OR = 2.20(95% CI: 1.38, 3.50)), history of sharing sharp material (OR = 1.88 (95% CI: 1.07, 3.31)), blood transfusion (OR = 2.41 (95% CI: 1.62, 3.57)), family history of HBV (OR = 4.87 (95% CI: 2.95, 8.05)) and history needle injury (OR = 2.62 (95% CI: 1.20, 5.72)) were significant risk factors associated with HBV infection among pregnant women.

CONCLUSIONS

The pooled prevalence of HBV infection among pregnant women in East Africa was an intermediate level and different across countries ranging from 1.5% to 22.2%. The result of this pooled prevalence was an indication of the need for screening, prevention, and control of HBV infection among pregnant women in the region. Therefore, early identification of risk factors, awareness creation on the mode of transmission HBV and implementation of preventive measures are essential in reducing the burden of HBV infection among pregnant women.

Seroprevalence of hepatitis B virus infection and factors associated among pregnant women in Ethiopia: A systematic review and meta-analysis

BACKGROUND

Hepatitis B virus infection is a major public health problem among pregnant women worldwide. Hepatitis B virus is highly infectious and is the most common cause of morbidity and mortality among pregnant women, and evidence is scarce on the pooled seroprevalence of hepatitis B virus in Ethiopia.

OBJECTIVES

This study aimed to investigate the pooled seroprevalence of hepatitis B virus infection and factors associated with pregnant women in Ethiopia.

DESIGN

A systematic review and meta-analysis was employed in accordance with the Preferred Reporting Items for Systematic Reviews.

DATA SOURCES

Searches were carried out in biomedical databases such as PubMed/Medline, Science Direct, Web of Science, Google Scholar, Hinari, and the Cochrane Library published in English until June 2023.

METHODS

Observational study designs were selected. Endnote citation manager was used to collect and organize the search outcomes and remove duplicate articles. The data were extracted using a Microsoft Excel spreadsheet and exported to STATA 16.0 software for the analysis.

RESULTS

A total of 48 research articles were included in the final analysis. The pooled estimated sero prevalence of hepatitis B virus infection among pregnant women in Ethiopia was 5.78% (95% confidence interval = 5.14, 6.43). History of abortion (odds ratio = 6.56, 95% confidence interval = 4.88, 8.90), history of blood transfusion (odds ratio = 5.74, 95% confidence interval = 4.04, 8.16), history of hospitalization (odds ratio = 5.40, 95% confidence interval = 3.68, 7.94), history of multiple sexual partner (odds ratio = 5.80, 95% confidence interval = 3.71, 9.05), history of surgical procedure (odds ratio = 7.39, 95% confidence interval = 4.16, 13.14), history of tattooing (odds ratio = 4.59, 95% confidence interval = 2.83, 7.43), and history of tooth extraction (odds ratio = 4.46, 95% confidence interval = 2.42, 8.22) were significantly associated with hepatitis B virus infection among pregnant women in Ethiopia.

CONCLUSION

The overall pooled prevalence of hepatitis B virus infection among pregnant women in Ethiopia is relatively high. Having a history of abortion, blood transfusion, hospitalization, multiple sexual partners, surgical procedures, tattooing, and tooth extraction were found to be risk factors for hepatitis B virus. Therefore, extensive screening programs for hepatitis B virus in all pregnant women in Ethiopia are needed to prevent further infection and decrease the vertical transmission caused by the disease.

Seroprevalence and Associated Factors of HBV and HCV among Pregnant Women Attending Antenatal Care at Debre Tabor Comprehensive Specialized Hospital, Northwest Ethiopia: A Cross-Sectional Study

Background

Infections with the hepatitis B virus (HBV) and the hepatitis C virus (HCV) are worldwide problems that particularly place a heavy burden on developing nations. HBV and HCV infections during pregnancy have a high rate of vertical transmission and harmful consequences for both the mother and the child. Therefore, this study was carried out to assess the seroprevalence and associated factors of HBV and HCV infections among pregnant women attending antenatal care at Debre Tabor Comprehensive Specialized Hospital in Ethiopia.

Methods

A cross-sectional study was conducted from March 15th to September 16th, 2022, at the Debre Tabor Comprehensive Specialized Hospital antenatal care clinic. Five milliliters of venous blood were collected from 422 pregnant women selected using a simple random sampling method. Data on sociodemographic characteristics and risk factors were collected using a prestructured questionnaire. A chi-square test, bivariate, and multivariate analyses were used to evaluate the association between dependent and independent variables. p values less than 0.05 were considered statistically significant.

Results

The seroprevalence of HBV and HCV infections was found to be 13% and 0.5%, respectively. Undertaking blood transfusion (AOR = 14.2, CI = 5.81-34.526, p = 0.001), tattooing (AOR = 3.99, CI = 1.1-14.36, p = 0.034), and dental therapy (AOR = 4.9, CI = 1.41-17.025, p = 0.012) were significantly associated with HBV infection.

Conclusion

HBV infection in pregnant women was shown to have a high endemicity (13%) in this investigation, whereas the seroprevalence of HCV infection was low (0.5%). HBV infection was significantly associated with a history of blood transfusions, tattooing, and dental therapy. Screening pregnant women for HBV and HCV infections and providing effective therapy would ensure better outcomes for the newborn. In addition, health education must be used to increase knowledge of screening and modes of transmission.

High Seroprevalence of Hepatitis B and C Virus Infections among Pregnant Women Attending Antenatal Clinic in Borumeda General Hospital, Northeast Ethiopia

Background

Viral hepatitis are considered as the cause of solemn health problem for the human kind, particularly among pregnant women in the 21^th century. Therefore, this study is aimed at determining the seroprevalence of HBV and HCV infection among pregnant women attending at Borumeda General Hospital, Dessie, Northeast Ethiopia.

Methods

An institution-based cross-sectional study was conducted at Borumeda General Hospital from April to May, 2020. A consecutive total of 124 pregnant women who were attending at the antenatal clinic (ANC) of the hospital were included. A structured questionnaire was used to assess the associated factors and some sociodemographic characteristics. Five milliliters of venous blood was collected from each study participant, and a laboratory test using a rapid HBsAg and anti-HCV kit was done. The data were analyzed using SPSS software version 22.

Results

The mean age of the study subjects was 25.81 (±5.967) years. The overall seroprevalence of either HBV or HCV infections among the study participants was 14 (11.3%). HBsAg and anti-HCV were positive among 10 (8.1%) and 4 (3.2%) study participants, respectively. There was no coinfection result between HBV and HCV among pregnant women. Pregnant women who had abortion history [AOR 5.723; 95% CI 1.100-29.785, P value = 0.038] and hospitalization history with IV medication [AOR 6.939; 95% CI 1.017-47.322, P value = 0.048] exhibited statistically significant association with HBV infection.

Conclusions

Seroprevalence of HBV and HCV infections among pregnant women was high, and the rate of HBV particularly can be considered in the high endemic category of the WHO classification scheme. Continuous screening of pregnant mothers, provision of hepatitis B vaccine for females at the child-bearing age, and health education to create awareness about HBV and HCV should be implemented.
