A Sidney Barritt, Ravi Jhaveri
PURPOSE OF REVIEW: Increasing hepatitis C virus (HCV) cases over the past decade have raised concerns about subsequent increased cases in infants due to mother to child transmission (MTCT). Many are reminded of the early days of HIV and the rationale for using antiretroviral agents during pregnancy. RECENT FINDINGS: Direct-acting antivirals (DAAs) that are highly potent, all-oral, short-duration regimens that cure HCV have led many to consider what it would entail to use DAAs for pregnant women...

Background: A case of mother to child transmission (MTCT) of HIV at a medical center in Washington, DC, resulted in the implementation of universal opt-out rapid testing of patients admitted for delivery. This article evaluates the policy's efficacy and implementation. Methods: We evaluated the implementation using the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. Results: We could not evaluate decrease in MTCT rate secondary to low sample size ( n  = 3324) and no true-positive results...

BACKGROUND: Evidence of 24-months survival in the frame of prevention of mother-to-child transmission (PMTCT) cascade-care is scare from routine programs in sub-Saharan African (SSA) settings. Specifically, data on infant outcomes according to feeding options remain largely unknown by month-24, thus limiting its breath for public-health recommendations toward eliminating new pediatric HIV-1 infections and improving care. We sought to evaluate HIV-1 vertical transmission and infant survival rates according to feeding options...

Chronic hepatitis B virus (HBV) infection is an enormous economic and social burden. Asian countries such as Vietnam, Mongolia, Laos, China, the Philippines, South Korea, Singapore and Cambodia have high or high-intermediate HBsAg prevalence. Most of the chronic HBV carriers in this region acquire their infection during early childhood or through mother-to-child transmission (MTCT). Asia has been highly successful in controlling HBV in the last 2 decades. For example, China has adopted a comprehensive strategy to control HBV and has offered universal HBV vaccination to infants since 1992...

Background: Preventing mother-to-child transmission of human immunodeficiency virus transmission (MTCT) depends on early initiation of antiretroviral therapy (ART). We report the 18-month MTCT risk during the transition from Option A to Option B+ in Zimbabwe, and assess whether ART preconception could eliminate MTCT in breastfeeding populations. Methods: In 2013, we consecutively recruited a nationally representative sample of 6051 infants aged 4-12 weeks and their mothers from 151 immunization clinics using a multistage stratified cluster sampling method...

Prophylaxis and treatment with antiretroviral drugs have resulted in a very low rate of mother-to-child transmission (MTCT) of HIV during recent years. Registration of new antiretroviral drugs, modification of clinical praxis, updated general treatment guidelines and increasing knowledge about MTCT have necessitated regular revisions of the recommendations for 'Prophylaxis and treatment of HIV-1 infection in pregnancy'. The Swedish Reference Group for Antiviral Therapy (RAV) has updated the recommendations from 2013 at an expert meeting 19 September 2017...

Mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV-1) contributes to an estimated 150,000 new infections annually. Maternal vaccination has proven safe and effective at mitigating the impact of other neonatal pathogens and is one avenue toward generating the potentially protective immune responses necessary to inhibit HIV-1 infection of infants through breastfeeding. In the present study, we tested the efficacy of a maternal vaccine regimen consisting of a modified vaccinia virus Ankara (MVA) 1086...

Hepatitis B virus (HBV) is a significant public health issue that has not been adequately addressed, especially in the high-prevalence region of Africa. Despite the incorporation of HBV vaccines into the Expanded Program on Immunization (EPI), children continue to be infected with HBV through maternal-to-child transmission (MTCT). The addition of a birth dose of HBV vaccine would be a cost-effective method to reduce MTCT. Birth-dose HBV vaccine policies have been adopted in the Western Pacific region but have yet to be implemented in the African region...

BACKGROUND: East and South Africa contributes 59% of all pediatric HIV infections globally. In Uganda, HIV prevalence among HIV exposed infants was estimated at 5.3% in 2014. Understanding the remaining bottlenecks to elimination of mother-to-child transmission (eMTCT) is critical to accelerating efforts towards eMTCT. This study determined factors associated with HIV positive sero-status among exposed infants attending mother-baby care clinics in rural Kasese so as to inform enhancement of interventions to further reduce MTCT...

BACKGROUND: Sexually transmitted infections (STIs) including Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and cytomegalovirus (CMV) may lead to adverse pregnancy and infant outcomes. The role of combined maternal STIs in HIV mother-to-child transmission (MTCT) was evaluated in mother-infant pairs from NICHD HPTN 040. METHODOLOGY: Urine samples from HIV-infected pregnant women during labor were tested by polymerase chain reaction (PCR) for CT, NG, and CMV...

Background: Achieving World Health Organization (WHO) recommendations for postnatal care (PNC) within the first few weeks of life is vital to eliminating early mother-to-child transmission of HIV (MTCT) and improving infant health. Almost half of the annual global deaths among children under five occur during the first six weeks of life. This study aims to identify uptake of three PNC visits within the first six weeks of life as recommended by WHO among South African mother-infant pairs, and factors associated with uptake...

Background: Poor awareness and knowledge of mother-to-child transmission (MTCT),that accounts for over 90% of new HIV infections among children, might contribute to the HIV epidemics. In Ethiopia, 898 400 children are orphaned due to HIV and AIDS and 200 300 were living with HIV in 2013. The main objective of this study was to examine the knowledge of MTCT of HIV, its prevention (PMTCT) and associated factors among Ethiopian women. Methods: We conducted a cross-sectional analysis among 16 515 women from the Ethiopian Demographic Health Survey (EDHS) 2011...

Globally, 150,000 new paediatric human immunodeficiency virus type 1 (HIV-1) infections occurred in 2015. There remain complex challenges to the global elimination of paediatric HIV-1 infection. Thus, for the global community to achieve elimination of new paediatric HIV-1 infections, innovative approaches need to be explored. Immune-based approaches to prevention of mother-to-child transmission (MTCT) may help fill some of the remaining gaps and provide new opportunities to achieve an AIDS-free generation. Immune-based interventions to prevent MTCT of HIV-1 may include paediatric HIV vaccines and passive immunization approaches...

The majority of infants' breastfeeding from their HIV-infected mothers do not acquire HIV-1 infection despite exposure to cell-free virus and cell-associated virus in HIV-infected breast milk. Paradoxically, exclusive breastfeeding regardless of the HIV status of the mother has led to a significant decrease in mother-to-child transmission (MTCT) compared with non-exclusive breastfeeding. Although it remains unclear how these HIV-exposed infants remain uninfected despite repeated and prolonged exposure to HIV-1, the low rate of transmission is suggestive of a multitude of protective, short-lived bioactive innate immune factors in breast milk...

BACKGROUND: Stigma and discrimination ontinue to undermine the effectiveness of the HIV response. Despite a growing body of evidence of the negative relationship between stigma and HIV outcomes, there is a paucity of data available on the prevalence of stigma and its impact. We present a probabilistic cascade model to estimate the magnitude of impact stigma has on mother-to-child-transmission (MTCT). METHODS: The model was parameterized using 2010 data from Johannesburg, South Africa, from which loss-to-care at each stage of the antenatal cascade were available...

BACKGROUND/AIMS: A birth dose of hepatitis B immunoglobulin (HBIG), in combination with hepatitis B vaccine (HepB), is recommended for infants born to hepatitis B surface antigen (HBsAg)-positive mothers. However, the optimal dosage of HBIG remains to be resolved. This prospective cohort study aimed to compare the efficacy of two dosages of HBIG combined with HepB to prevent mother-to-child transmission (MTCT) of HBV. METHODS: From 2009 to 2011, we prospectively enrolled mother-infant pairs with positive maternal HBsAg in China...

Many factors have been identified to influence the risk of mother to child transmission (MTCT) of HIV. Chief amongst these is high maternal VL and advanced disease. High maternal viral load (mVL), measured at delivery, has been described as the strongest risk factor for both in utero (IU) and intrapartum (IP) transmission. Similarly, CD4+ T cell count and clinical stage of infection are also the confirmed significant predictors of transmission. Correspondingly, higher mVL in the genital tract has also been independently associated with a higher risk of MTCT of HIV-1...
