Abstract
AbstractProblemHepatitis B is one of the leading causes of mortality in India. Despite the mass vaccination programme, the burden of the infection is still increasing due to its vertical transmission. Asymptomatic nature of hepatitis B virus (HBV) infection owing to immune tolerance among pregnant women is a major issue in this regard.Method of studyAs such, this study aims to investigate the potential role of altered Toll‐like receptor (TLR) expression (TLR‐3, 7 and 9) along with peripheral blood HBeAg status in attaining differential cord blood (CB) HBV DNA status.ResultExpression analysis reveals an overall downregulation of expression with mean ± SD value 1.14 ± 1.05, 0.86 ± 0.5 and 0.71 ± 0.4 (TLR 3, 7 and 9, respectively) upon comparison with healthy women. Further stratification based on CB HBV DNA status; the downregulation of expression was found to be significantly (p < .05) associated with positive CB HBV DNA status apart from peripheral HBeAg status. One hundred percent HBeAg positive parturiting women exhibit positive CB HBV DNA. Pearson's correlation analysis reveals a positive correlation between CB HBV DNA status and altered TLR expression, HBeAg status and mother HBV DNA status and as such can be associated with the potential risk of HBV vertical transmission.ConclusionThis study suggests that the downregulation of TLR 3, 7 and 9 may be a risk factor for potential vertical transmission of HBV.
