Determining the Prevalence of Hepatitis Delta Virus, Hepatitis C Virus, and HIV Among Mothers and Infants with Hepatitis B Virus Chronic Infection

Infection with hepatitis B, C, and delta viruses (HBV/HCV/HDV) caused by mother-to-child transmission (MTCT) is still a serious health problem worldwide. Coinfection with HBV/HDV or HCV has been shown to accelerate the progression of chronic HBV infection, resulting in higher mortality.

The aim of this study was to evaluate the prevalence of anti-HCV, anti-HDV, and anti-HIV antibodies in mothers with chronic HBV infection and their infants.

This cross-sectional study was performed on 100 mothers with chronic HBV (hepatitis B surface antigen-positive [HBsAg+]/hepatitis B core antibody-positive [HBcAb+]) and their infants between 2020 and 2021 in northeastern Iran. The presence of serological markers of HBV, anti-HCV, anti-HDV, and HIV antibodies, as well as the liver function tests, were evaluated in all mothers. The obtained data were analyzed using SPSS version 20, and the level of the statistical significance was set at a P-value < 0.05.

The mean age in all individuals was 37.45 ± 17.95 years. In mothers with chronic HBV and their infants, 3, 11, and 15% were serologically positive for anti-HCV, HCV/HDV, and anti-HDV, respectively. Also, all participants were serologically negative for anti-HIV. A statistical analysis showed a significant correlation of anti-HDV (95% CI, 0.113 - 0.332) with education, place of residence, and anti-HCV (95% CI, 0.313 - 0.416) in mothers with chronic HBV. The percentages of mothers and infants with simultaneous infection HBV were reported to be 1, 2, and 1% when anti-HCV, anti-HDV, and anti-HCV/HDV antibodies were measured, respectively.

Intellectual strategies in the diagnosis of HCV, HIV, and HDV in patients with chronic HBV have challenged public and global health, and preventing viral infections in newly born infants is the most effective way to control the HBV/HCV or HDV epidemic.
