6.1.16 In the absence of obstetric complications, normal vaginal delivery can be recommended if the mother has fully suppressed HIV viral load on cART. Grading: 1C No data exist to support any benefit from PLCS in mothers with HBV/HIV co-infection and no robust RCT Sotrastaurin cell line exists in HBV mono-infected women. In a meta-analysis of mono-infected HBV women (four randomized trials all from China involving 789 people were included) where routine HBV neonatal vaccine and HBIG were used, there was strong evidence that pre-labour Caesarean

section versus vaginal delivery could effectively reduce the rate of mother-to-infant transmission of HBV (RR 0.41; 95% CI 0.28–0.60) [203]. However, methodological concerns including lack of information on randomization procedure, lack of allocation concealment and lack of blinding make the role of PLCS for preventing mother-to-child transmission of HBV uncertain. In addition, a meta-analysis of six RCTs where lamivudine was used from the third trimester has demonstrated that lamivudine is effective click here in reducing transmission (HR: 0.31; 95% CI 0.15–0.63) [204]. Similarly, a single RCT in women positive for HBsAg

and with an HBV DNA > 106 IU/mL demonstrated that telbivudine was also effective in reducing MTCT for HBV (2.11% vs. 13.4%; P < 0.04) and lowering risk of postpartum ALT flare. Hence, the lack of a scientifically robust RCT evaluating the role of CS in preventing MTCT for mothers with HBV mono-infection and the lack of any cohort or RCT data to support the use of CS in co-infection argue against advocating this in co-infected

mothers. Although HBV DNA levels are increased as a result of HIV, the efficacy of lamivudine as well as telbivudine in reducing medroxyprogesterone the rate of intrapartum transmission in mono-infection, the efficacy of lamivudine, tenofovir and emtricitabine as part of cART in reducing HBV DNA in non-pregnant co-infected patients, and the use of tenofovir with either lamivudine or emtricitabine as standard practice in co-infected patients, collectively provide further reason against recommending CS in those co-infected. 6.1.17 Neonatal immunization with or without HBIG should commence within 24 hours of delivery. Grading: 1A Immunoprophylaxis with HBV vaccine with or without HBIG given to the neonate has been shown in separate meta-analyses of RCTs to significantly reduce MTCT from HBV mono-infected women. HBIG should be administered to the neonate if maternal HBV DNA concentration is > 106 IU/mL [205]. In the absence of neonatal immunization with HBV vaccine with or without HBIG, the rate of MTCT from a mono-infected mother who is HBsAg and HBeAg-positive is 70–90% and for women who are HBsAg-positive but HBeAg-negative, 10–40%. By co-administering vaccination (effectiveness of vaccine vs. placebo RR: 0.28; 95% CI 0.2–0.4) and HBIG (effectiveness of HBIG/vaccine vs. vaccine alone RR: 0.54; 95% CI 0.41–0.73), transmission rates can be reduced to between 0% and 14%.
