Co-infection of HIV or HCV among HBsAg positive delivering mothers and its associated factors in governmental hospitals in Addis Ababa, Ethiopia: A cross-sectional study.

BACKGROUND

Blood borne viral infections such as Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Human Immunodeficiency virus (HIV) cause substantial mortality and morbidity worldwide. Viral hepatitis during pregnancy is closely related to high risks of maternal and neonatal complications. In Ethiopia, only a little information is available on co-infection of HCV or HIV among Hepatitis B surface Antigen (HBsAg) positive pregnant mothers. Thus, the study aimed to determine HIV or HCV co-infection and associated risk factors among HBsAg positive delivering mothers.

METHOD

A health facility-based cross-sectional study was conducted in five governmental hospitals in Addis Ababa among 265 HBsAg positive delivering mothers in the year 2019 and 2020. A purposive sampling technique was used to select the study participants. Structured questionnaires and laboratory test results were used to collect the data. SPSS version 20 software was used to enter and analyze the data. Multivariable logistic regression was used to identify independent predictors of HIV or HCV co-infections.

RESULTS

Of the HBsAg positive delivering mothers, 9 (3.4%) and 3 (1.1%) were co-infected with HIV and HCV, respectively. None of them were with triplex infection. All of the socio-demographic characteristics were not significantly associated with both HIV and HCV co-infections. Mothers who had a history of sexually transmitted diseases (STDs) were 9.3 times more likely to have HBV-HIV co-infection (AOR = 9.3; 95% CI: 1.84-47.1). Mothers who had multiple sexual partners were 5.96 times more likely to have HIV co-infection (AOR = 5.96; 95% CI: 1.074-33.104). The odds of having HBV-HIV co-infection were 5.5 times higher among mothers who had a history of sharing shavers, razors, and earrings (AOR = 5.5;95% CI: 1.014-29.69). HCV co-infection was not significantly associated with any of the potential risk factors.

CONCLUSION

This dual infection rate of HBsAg positive delivering mother with HIV or HCV indicates that a substantial number of infants born in Ethiopia are at high risk of mother-to-child transmission (MTCT) of HBV, HIV, and HCV. Thus, all pregnant mothers need to be screened for HBV, HCV, and HIV during antenatal care, and also need implementation of prevention mechanisms of MTCT of these viral infections.
