    Full Text Available In this study, a mathematical model of HIV/AIDS mother to child transmission to analyze the effectiveness of prevention of HIV mother to child transmission programmes has been presented. The result reveals that prevention of HIV mother to child transmission programmes focusing only on biological transmission cannot control the increase of the HIV mother to child transmission in India. Hence, to control the HIV MTCT epidemic in India, in spite of strengthening the PMTCT programmes to reduce transmission rates, effective measures should be taken to prevent HIV infection in women of reproductive ages. Since the overall HIV MTCT epidemic is dependent on the HIV incidence in women of reproductive age group, the integration of pediatric HIV model with a detailed model of adult HIV would be investigated in future studies in order to model these dynamics more accurately.

    Despite the availability of highly efficacious antiretroviral drug regimens for the prevention of mother-to-child HIV transmission (PMTCT), transmission rates remain higher than those achieved in clinical trials. Access to these efficacious drug regimens continues to expand rapidly in countries most affected by HIV. Such expansion is an important first step in dramatically reducing mother-to-child HIV transmission rates. However, beyond access to drug regimens, programs must also identify and...

    Full Text Available Behailu Merdekios1, Adebola A Adedimeji2 1College of Medicine and Health Sciences, Arba Minch University, Ethiopia; 2Albert Einstein College of Medicine, Jack and Pearl Resnick Campus, New York, USA Background: In Ethiopia, Progress in Reducing Mother-to-Child-Transmission (PMTCT of human immunodeficiency virus (HIV is being curtailed by behavioral and cultural factors that continue to put unborn children at risk, and mother-to-child transmission is responsible for more than 90% of HIV infection in children. The objective of this study was to assess PMTCT services by examining knowledge about reducing vertical transmission among pregnant women. Methods: A multistaged sampling institution-based survey was conducted in 113 pregnant women in Arba Minch. Qualitative and quantitative data were obtained. Results: Of the 113 respondents, 89.4% were from Arba Minch, 43.4% were at least 25 years of age, 73.4% had formal education at primary level or above, 100% reported acceptance of voluntary counseling and testing, 92.0% were knowledgeable about mother-to-child transmission, and 90.3% were aware of the availability of the PMTCT service in the health facility. Of 74 HIV-positive women in PMTCT, only three (4.1% had had skilled birth attendants at delivery. There was an unacceptable degree of loss of women from PMTCT. Maternal educational level had a statistical association with income (P < 0.001 and voluntary counseling and testing for pregnant women (P < 0.05. Factors that determined use of PMTCT included culture, socioeconomic status, and fear of stigma and discrimination. Conclusion: In the area studied, intervention to reduce mother-to-child transmission of HIV is failing to reach its goal. This is an alarming discovery requiring quick reconsideration and strengthening of preventive strategies at all levels.

    Definitive diagnosis of HIV infection in infants mothers is still posing some difficulty in Nigeria and other developing countries. Within this age definitive diagnosis can only be carried out by antigen based techniques which are indeed not available in these developing countries. This has resulted in the absence of authoritative data on the rate of mother-to-child transmission in these countries. Nigeria inclusive. The present pilot study was therefore carried out to generate some information on the rate of mother to child transmission in Nigeria using the PCR technique. Plasma samples were obtained from 68 children of both sexes less than 18 months of age and who were born to HIV infected mothers. The samples were collected from two pediatric departments. in Lagos and in Benin. The presence of HIV 1 RNA in each of the samples. was determined using the Amplicor Monitor V 1.5 technique (Roche Diagnostics). Data showed that HIV-1 RNA was detected in 15 of the 68 samples tested. This gave an HIV-1 RNA detection rate of 22%. Among women who had some intervention, the rate of transmission of infection was 11% while the rate among those without intervention was 30%. The 22% transmission rate recorded in this study is close to the range of 25 to 35% that has been reported in several developed and a few developing countries. A multicenter nationwide study will still be needed to determine the national mother to child transmission rate in Nigeria.

There is also increasing evidence that male partner involvement positively impacts non-HIV related outcomes, such as skilled attendance at delivery, exclusive breastfeeding, uptake of effective contraceptives, and infant immunizations. Despite these associations, male partner involvement remains low, especially when offered in the standard antenatal clinic setting. In this review we explore strategies for improving rates of antenatal male partner HIV testing and argue that the role of male partners in PMTCT must evolve from one of support for HIV-infected pregnant and breastfeeding women to one of comprehensive engagement in prevention of primary HIV acquisition, avoidance of unintended pregnancies, and improved HIV-related care and treatment for the HIV-infected and uninfected women, their partners, and children. Involving men in all components of PMTCT has potential to contribute substantially to achieving virtual elimination of mother-to-child HIV transmission; promoting partner-friendly programs and policies, as well as pursuing research into numerous gaps in knowledge identified in this review, will help drive this process.

    Full Text Available Background: The Mahalapye district health management team (DHMT conducts regular audits to evaluate the standard of services delivered to patients, one of which is the prevention of mother-to-child-transmission (PMTCT programme. Xhosa clinic is one of the facilities in Mahalapye which provides a PMTCT programme.Aim: This audit aimed to identify gaps between the current PMTCT clinical practice in Xhosa clinic and the Botswana PMTCT national guidelines.Setting: This audit took place in Xhosa clinic in the urban village of Mahalapye, in the Central District of Botswana.Methods: This was a retrospective audit using PMTCT Xhosa clinic records of pregnant mothers and HIV-exposed babies seen from January 2013 to June 2013.Results: One hundred and thirty-three pregnant women registered for antenatal care. Twenty-five (19% knew their HIV-positive status as they had been tested before their pregnancy or had tested HIV positive at their first antenatal clinic visit. More than two-thirds of the 115 pregnant women (69% were seen at a gestational age of between 14 and 28 weeks. About two-thirds of the pregnant women (67% took antiretroviral drugs. Of the 44 HIV-exposed infants, 39 (89% were HIV DNA PCR negative at 6 weeks. Thirty-two (73% children were given cotrimoxazole prophylaxis between 6 and 8 weeks.Conclusion: The PMTCT programme service delivery was still suboptimal and could potentially increase the mother-to-child transmission of HIV. Daily monitoring mechanism to track those eligible could help to close the gap.

    The main objective in the management of HIV-infected pregnant women is prevention of mother-to-child transmission; therefore, it is essential to provide universal antiretroviral treatment, regardless of CD4 count. All pregnant women must receive adequate information and undergo HIV serology testing at the first visit. We assembled a panel of experts appointed by the Secretariat of the National AIDS Plan (SPNS) and the other participating Scientific Societies, which included internal medicine physicians with expertise in the field of HIV infection, gynecologists, pediatricians and psychologists. Four panel members acted as coordinators. Scientific information was reviewed in publications and conference reports up to November 2012. In keeping with the criteria of the Infectious Diseases Society of America, 2levels of evidence were applied to support the proposed recommendations: the strength of the recommendation according to expert opinion (A, B, C), and the level of empirical evidence (I, II, III). This approach has already been used in previous documents from SPNS. The aim of this paper was to review current scientific knowledge, and, accordingly, develop a set of recommendations regarding antiretroviral therapy (ART), regarding the health of the mother, and from the perspective of minimizing mother-to-child transmission (MTCT), also taking into account the rest of the health care of pregnant women with HIV infection. We also discuss and evaluate other strategies to reduce the MTCT (elective Cesarean, child's treatment…), and different aspects of the topic (ARV regimens, their toxicity, monitoring during pregnancy and postpartum, etc.).

    Mother-to-child transmission (MTCT) is the leading cause of paediatric HIV-infection in Israel. This study aimed to assess MTCT rates and analyse temporal changes in relation to highly active antiretroviral therapy (HAART) introduction in 1996. This historical prospective study included all HIV-infected women who delivered in Israel between 1988 and 2011. Demographic, clinical, laboratory and therapy characteristics were compared between HIV-infected newborns with all others, and between infants born before and after 1996. Of all 796 infants born in Israel to HIV-infected women, 25 (3·1%) were infected. MTCT rates decreased significantly after HAART introduction compared with infants who were born before 1996 (16·3% vs. 1·7%). Mothers who infected vertically were more likely to be younger, Ethiopian-born, delivered trans-vaginally, not treated with HAART during pregnancy/labour and delivered before 1996 compared with mothers who did not transmit the HIV to their neonates. Newborns who did not receive antiretroviral therapy postpartum were more commonly HIV-infected and their mortality rate was higher. In conclusion, HAART during pregnancy/labour decreased MTCT significantly. Most MTCT in Israel was recorded among Ethiopian migrants, yet, in decreasing rates. Continuous efforts should be employed to encourage early HIV testing and allow effective HAART to pregnant women who belong to a key risk-group.

    More than 90% of human immunodeficiency virus type 1 (HIV-1) infection in children is acquired by mother-to-child transmission. However, infection of the child occurs in between 14 and 35% of cases. To understand the mechanisms involved in HIV-1 transmission, we have investigated the antigenic, molecular, and phenotypic characteristics of the virus harbored in infected mothers and their children. A clear correlation was observed between the transmission of the virus and the isolation of viral variants with a rapidly replicating and syncytium-inducing phenotype from the mother. Furthermore, non-transmitting mothers were able to neutralize several primary isolates more frequently than transmitting mothers. The comparison of the viral phenotype and genotype of mother-child pairs showed that the transmitted virus did not have common features, suggesting that transmission is usually not a selective process. This study suggests that transmission is governed by an interaction of both viral and immunological factors. The results obtained indicate that different strategies can be applied for the prevention of transmission.

    Various interventions to prevent mother-to-child-transmission (MTCT) of HIV have been investigated and implemented. A number of systematic reviews assessing the efficacy of interventions for the prevention of MTCT of HIV reported antiretroviral prophylaxis, caesarean section before labour and before ruptured membranes, and complete avoidance of breastfeeding were efficacious for preventing MTCT of HIV. Recent WHO guidelines recommend lifelong antiretroviral therapy for all pregnant women for treatment of the woman's own HIV infection and for prevention of MTCT of HIV. Therefore, the objective of this overview is to evaluate the currently available systematic reviews of interventions for preventing MTCT of HIV, and to identify the current best evidence-based interventions for reducing the risk of MTCT of HIV. We will include only peer-reviewed systematic reviews of randomised or quasi-randomised controlled trials assessing the effects of interventions for preventing MTCT of HIV that target both HIV-infected women and children aged 2 years and younger born to HIV-infected women. We will search the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effectiveness, Ovid MEDLINE and EMBASE. We will assess review eligibility, the methodological quality of included systematic reviews using A Measurement Tool to Assess The Systematic Reviews and will extract data, comparing our results and resolving discrepancies by consensus. Finally, we will independently assess the certainty of the evidence using Grades of Recommendation, Assessment, Development and Evaluation. Ethics approval is not required. We will publish the results in a peer-reviewed journal and present at conferences, which will inform future research and will be useful for healthcare managers, administrators and policymakers to guide resource allocation decisions and optimisation of interventions to prevent the MTCT of HIV. © Article author(s) (or their employer(s) unless

    The objective of this paper is to review experience in prevention of mother-to-child transmission (PMTCT) of HIV in Georgia. PMTCT is one of the strategic priorities in Georgia. The first case of HIV infection in pregnant women was reported in 1999. Starting 2005 the National Programme on PMTCT became operational. One hundred sixteen HIV voluntary counselling and testing (VCT) centers operate throughout the country at antenatal clinics. According to the National PMTCT protocol, all first time attending pregnant women are offered Voluntary Counselling and Testing (VCT). Testing on HIV/AIDS is based on identification of HIV antibodies by screening method and all positive results are referred to the Infectious Diseases, AIDS and Clinical Immunology Research Center (IDACIRC) for the further investigation (confirmation by Western Blot assay) and further management. Data collection was made retrospectively, using information from IDACIRC National HIV/AIDS Data Base, VRF for the period 1999-2007. Prevalence of HIV among pregnant women availing VCT services in 2006 was 0.03%. As of December, 2007 total 69 pregnancies of 64 women were registered at the IDACIRC. Fifty eight women (90.6%) acquired infection through heterosexual contact. None of the HIV positive women reported intravenous injection of illicit drugs. The majority of the HIV infected pregnant women had one sexual partner (90.6%). Of children delivered by 51 positive partners 41(80%) were infected through injecting drugs intravenously and 10 (20%) persons through heterosexual contacts. Throughout the period 1999-2007 14 pregnant women received PMTCT services only partially. In 2 cases children were HIV-infected. In 12 pregnancies women received AZT in about the 28th week of pregnancy. No case of HIV transmission to child was recorded in this group. In 32 cases pregnant women received full prophylaxis therapy and all children were negative for HIV infection. Among 6 pregnant women admitted at IDACIRC later than

    Viral CCR5 usage is not a predictive marker of mother to child transmission (MTCT) of HIV-1. CXCR4-using viral variants are little represented in pregnant women, have an increased although not significant risk of transmission and can be eventually also detected in the neonates. Genetic polymorphisms are more frequently of relevance in the child than in the mother. However, specific tissues as the placenta or the intestine, which are involved in the prevalent routes of infection in MTCT, may play an important role of selective barriers. The virus phenotype of the infected children, like that of adults, can evolve from R5 to CXCR4-using phenotype or remain R5 despite clinical progression to overt immune deficiency. The refined classification of R5 viruses into R5(narrow) and R5(broad) resolves the enigma of the R5 phenotype being associated with the state of immune deficiency. Studies are needed to address more in specific the relevance of these factors in HIV-1 MTCT and pediatric infection of non-B subtypes.

    To investigate the role of the HIV-1 phenotype in mother-to-child HIV-1 transmission, we evaluated coreceptor usage and replication kinetics in chemokine receptor-expressing U87MG.CD4 cells of primary isolates from 32 HIV-1-infected mothers of Italian origin, none under preventive antiretroviral therapy, and from their infected infants. Five of 15 mothers of infected children and 2 of 17 mothers of uninfected children harbored viruses able to use CXCR4 as coreceptor. However, all isolates used CCR5, alone or in association with CXCR4. The replicative capacity in coreceptor-expressing cells of the viral isolates did not differ between the two groups of mothers. All mothers with an R5 virus transmitted a virus with the same coreceptor usage, whereas those four with a multitropic virus transmitted such a virus in one case. Although the presence of a mixed viral population was documented in the mothers, we did not observe transmission solely of X4 viruses. Interestingly, the only child infected with a multitropic virus carried a defective CCR5 allele. Analysis of the env V3 region of the provirus from this child revealed infection with multiple viral variants with a predominance of R5-type over X4-type sequences. These findings show that CCR5 usage of a viral isolate is not a discriminating risk factor for vertical transmission. Furthermore, X4 viruses can be transmitted to the newborn, although less frequently. In particular, we document the transmission of multiple viral variants with different coreceptor usage in a Delta32 CCR5 heterozygous child, and demonstrate that the heterozygous genotype per se does not contribute to the restriction of R5-type virus spread.

    The objectives of this study were to determine HIV drug resistance (HIVDR) prevalence in Zambian infants upon diagnosis, and to determine how changing prevention of mother-to-child transmission (PMTCT) drug regimens affect drug resistance. Dried blood spot (DBS) samples from infants in the Lusaka District of Zambia, obtained during routine diagnostic screening, were collected during four different years representing three different PMTCT drug treatment regimens. DNA extracted from dried blood spot samples was used to sequence a 1493 bp region of the reverse transcriptase gene. Sequences were analyzed via the Stanford HIVDRdatabase (http://hivdb.standford.edu) to screen for resistance mutations. HIVDR in infants increased from 21.5 in 2007/2009 to 40.2% in 2014. Nonnucleoside reverse transcriptase inhibitor resistance increased steadily over the sampling period, whereas nucleoside reverse transcriptase inhibitor resistance and dual class resistance both increased more than threefold in 2014. Analysis of drug resistance scores in each group revealed increasing strength of resistance over time. In 2014, children with reported PMTCT exposure, defined as infant prophylaxis and/or maternal treatment, showed a higher prevalence and strength of resistance compared to those with no reported exposure. HIVDR is on the rise in Zambia and presents a serious problem for the successful lifelong treatment of HIV-infected children. PMTCT affects both the prevalence and strength of resistance and further research is needed to determine how to mitigate its role leading to resistance.

    The impact of the human immunodeficiency virus (HIV) epidemic in sub-Saharan Africa on future mortality rates of infants, children, and mothers, life expectancy, and economic growth is profound. Vertical transmission of HIV, transmission from mother to child, is a major factor in the increasing rates of HIV infection in sub-Saharan Africa. Vertical transmission of HIV occurs in utero, intrapartum during labor and delivery, and postpartum during breast-feeding. Because of the large numbers of HIV-infected mothers in developing countries, the majority trials regarding prevention of vertical transmission of HIV have been conducted in sub-Saharan Africa. Thus, sub-Saharan Africa has become a human laboratory, which demonstrates both the successes and failures of preventative methods to reduce vertical transmission of HIV. This review summarizes the body of research dedicated to understanding the pathophysiology of vertical transmission of HIV and pharmacology of inhibition of vertical transmission of HIV. While many debate the ethics of conducting trials in developing countries where effective prevention modalities have been slow to be implemented for economic, social and political reasons, studies continue and researchers continue to discover therapies and preventative methods, which may reduce the future devastation of HIV both in sub-Saharan Africa and throughout the world.

    Mother-to-child transmission (MTCT) is the overwhelming source of HIV-1 infection in young children. According to the World Health Organization (WHO), during the year 2003, despite effective antiretroviral (ARV) therapy, there were approximately 700,000 new infections in children worldwide, the majority of whom were from resource-limited countries. Alternative protocols to the long-course and complex regimens of ARV drugs, which in high-income countries have almost eradicated HIV MTCT, have been shown to reduce early transmission rates by 38-50%. However, the accumulation of drug resistance and the long-term toxicities of ARVs mean that alternative approaches need to be developed. Furthermore, transmission via breastfeeding, which accounts for one third of all transmission events, can reduce the benefits of short-course therapies given to women for the prevention of MTCT. The complex mechanisms and determinants of HIV-1 MTCT and its prevention in the different routes of transmission are still not completely understood. Despite the large contribution that many international agencies have made during the past 10-15 years in support of observational and intervention trials, as well as basic scientific research, HIV-1 MTCT intervention trials and basic research often are not integrated, leading to the generation of a fragmented picture. Maternal RNA levels, CD4+ T-cell counts, mode of delivery and gestational age were shown to be independent factors associated with transmission. However, these markers are only partial surrogates and cannot be used as absolute predictors of MTCT of HIV-1. Studies on the role of viral characteristics, immune response and host genomic polymorphisms did not always achieve conclusive results. Although CCR5-using viruses are preferentially carried by HIV-1 infected women as well as transmitted to their infants, the 32-basepair deletion of the CCR5 gene was not shown to influence perinatal MTCT. X4 viruses are apparently hampered in MTCT

    The main objective in the management of HIV-infected pregnant women is prevention of mother-to-child transmission; therefore, it is essential to provide universal antiretroviral treatment, regardless of CD4 count. All pregnant women must receive adequate information and undergo HIV serology testing at the first visit. If the serological status is unknown at the time of delivery, or in the immediate postpartum, HIV serology testing has to be performed as soon as possible. In this document, recommendations are made regarding the health of the mother and from the perspective of minimizing mother-to-child transmission.

    Full Text Available BACKGROUND: We performed a systematic review to assess the effect of integrated perinatal prevention of mother-to-child transmission of HIV interventions compared to non- or partially integrated services on the uptake in low- and middle-income countries. METHODS: We searched for experimental, quasi-experimental and controlled observational studies in any language from 21 databases and grey literature sources. RESULTS: Out of 28 654 citations retrieved, five studies met our inclusion criteria. A cluster randomized controlled trial reported higher probability of nevirapine uptake at the labor wards implementing HIV testing and structured nevirapine adherence assessment (RRR 1.37, bootstrapped 95% CI, 1.04-1.77. A stepped wedge design study showed marked improvement in antiretroviral therapy (ART enrolment (44.4% versus 25.3%, p<0.001 and initiation (32.9% versus 14.4%, p<0.001 in integrated care, but the median gestational age of ART initiation (27.1 versus 27.7 weeks, p = 0.4, ART duration (10.8 versus 10.0 weeks, p = 0.3 or 90 days ART retention (87.8% versus 91.3%, p = 0.3 did not differ significantly. A cohort study reported no significant difference either in the ART coverage (55% versus 48% versus 47%, p = 0.29 or eight weeks of ART duration before the delivery (50% versus 42% versus 52%; p = 0.96 between integrated, proximal and distal partially integrated care. Two before and after studies assessed the impact of integration on HIV testing uptake in antenatal care. The first study reported that significantly more women received information on PMTCT (92% versus 77%, p<0.001, were tested (76% versus 62%, p<0.001 and learned their HIV status (66% versus 55%, p<0.001 after integration. The second study also reported significant increase in HIV testing uptake after integration (98.8% versus 52.6%, p<0.001. CONCLUSION: Limited, non-generalizable evidence supports the effectiveness of integrated PMTCT programs. More research measuring coverage and

    Worldwide, mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV) represents the most common means by which children acquire HIV infection. Efficacious and effective interventions to prevent in utero and intrapartum transmission of HIV infection have been developed and implemented. However, a large proportion of MTCT of HIV occurs postnatally, through breast milk transmission. The objectives of this systematic review were to collate and assess the evidence regarding interventions to decrease late postnatal MTCT of HIV, and to determine the efficacy of such interventions in decreasing late postnatal MTCT of HIV, increasing overall survival, and increasing HIV-free survival. Electronic searches were undertaken using PubMed, EMBASE and other databases for 1980-2008. Hand searches of reference lists of pertinent reviews and studies, as well as abstracts from relevant conferences, were also conducted. Experts in the field were contacted to locate any other studies. The search strategy was iterative. Randomized clinical trials assessing the efficacy of interventions to prevent MTCT of HIV through breast milk were included in the analysis. Other trials and intervention cohort studies with relevant data also were included, but only when randomization was not feasible due to the nature of the intervention (i.e., infant feeding modality). Data regarding HIV infection status and vital status of infants born to HIV-infected women, according to intervention, were extracted from the reports of the studies. Six randomized clinical trials and one intervention cohort study were included in this review. Two trials addressed the issue of shortening the duration of (or eliminating) exposure to breast milk. In a trial of breastfeeding versus formula feeding, formula feeding was efficacious in preventing MTCT of HIV (the cumulative probability of HIV infection at 24 months was 36.7% in the breastfeeding arm and 20.5% in the formula arm [p = 0.001]), but the

    The objective of this study was to assess the level of integration of prevention of mother-to-child HIV transmission (PMTCT) in facilities providing services for maternal, newborn, and child health (MNCH) and reproductive health (RH) in Senegal. The survey, conducted from August through November, 2014, comprised five parts : a literature review to assess the place of this integration in the health policies, standards, and protocols in effect in Senegal; an analysis by direct observation of attitudes and practices of 25 healthcare providers at 5 randomly-selected obstetrics and gynecology departments representative of different levels of the health pyramid; a questionnaire evaluating knowledge and attitudes of 10 providers about the integration of PMTCT services into MNCH/RH facilities; interviews to collect the opinions of 70 clients, including 16 HIV-positive, about the quality of PMTCT services they received; and a questionnaire evaluating knowledge and opinions of 14 policy-makers/managers of health programs focusing on mothers and children about this integration. The literature review revealed several constraints impeding this integration : the policy documents, standards, and protocols of each of the programs involved do not clearly indicate the modalities of this integration; the programs are housed in two different divisions while the national Program against the Human Immunodeficiency Virus reports directly to the Prime Minister; program operations remains generally vertical; the resources for the different programs are not sufficiently shared; there is no integrated training module covering integrated management of pregnancy and delivery; and supervision for each of the different programs is organized separately.The observation of the providers supporting women during pregnancy, during childbirth, and in the postpartum period, showed an effort to integrate PMTCT into the MNCH/RH services delivered daily to clients. But this desire is hampered by many

    Background The prevention of mother-to-child transmission (PMTCT) of HIV has been focused mainly on women who are HIV-positive at their first antenatal visit, but there is uncertainty regarding the contribution to overall transmission from mothers who seroconvert after their first antenatal visit and before weaning. Method A mathematical model was developed to simulate changes in mother-to-child transmission of HIV over time, in South Africa. The model allows for changes in infant feeding practices as infants age, temporal changes in the provision of antiretroviral prophylaxis and counselling on infant feeding, as well as temporal changes in maternal HIV prevalence and incidence. Results The proportion of MTCT from mothers who seroconverted after their first antenatal visit was 26% (95% CI: 22-30%) in 2008, or 15 000 out of 57 000 infections. It is estimated that by 2014, total MTCT will reduce to 39 000 per annum, and transmission from mothers seroconverting after their first antenatal visit will reduce to 13 000 per annum, accounting for 34% (95% CI: 29-39%) of MTCT. If maternal HIV incidence during late pregnancy and breastfeeding were reduced by 50% after 2010, and HIV screening were repeated in late pregnancy and at 6-week immunization visits after 2010, the average annual number of MTCT cases over the 2010-15 period would reduce by 28% (95% CI: 25-31%), from 39 000 to 28 000 per annum. Conclusion Maternal seroconversion during late pregnancy and breastfeeding contributes significantly to the paediatric HIV burden, and needs greater attention in the planning of PMTCT programmes.

    Mother-to-child transmission (MTCT) of human immunodefi ciency virus (HIV) is a devastating consequence of HIV infection during pregnancy and is largely preventable. Evidence-based interventions such as universal antenatal screening, provision of antiretroviral therapy, delivery by elective caesarean section and avoidance of breastfeeding have ensured that the rates of MTCT remain low in Malaysia. This review discusses the most recent advances in the management of HIV infection in pregnancy with emphasis on antiretroviral treatment strategies and obstetric care in a middle income country.

    It is estimated that each HIV-positive child in South Africa costs the government more in terms of health and welfare expenses than it does to reduce mother-to-child transmission (MTCT) of HIV through the use of antiretroviral regimens (where the mother continues to breast-feed). Programmes to reduce MTCT of HIV/AIDS are, thus, clearly affordable. Using Nevirapine (according to the HIVNET 012 Protocol) saves more lives and [corrected] is more cost-effective than using Zidovudine (CDC 2 weeks regime).

    Background As antiretroviral treatment (ART) for HIV/AIDS is scaled-up globally, information on per-person costs is critical to improve efficiency in service delivery and maximize coverage and health impact. Objective To review studies on delivery unit costs for adult and pediatric ART provision per-patient-year, and prevention of mother-to-child transmission (PMTCT) interventions per mother-infant pair screened or treated, in low- and middle-income countries. Methods Systematic review of English, French and Spanish publications from 2001 to 2009, reporting empirical costing that accounted for at least antiretroviral (ARV) medicines, laboratory testing and personnel. Expenditures were analyzed by country income level and cost component. All costs were standardized to 2009 US dollars. Results Analyses covered 29 eligible, comprehensive costing studies. In the base case, in low-income countries (LIC), median, ART cost per patient-year was $792 (mean: $839, range: $682-$1089); for lower-middle-income countries (LMIC), the median was $932 (mean: $1246, range: $156-$3904); and for upper-middle-income countries (UMIC) the median was $1454 (mean: $2783, range: $1230-$5667). ARV drugs were largest component of overall ART cost in all settings (62%, 50% and 47% in LIC, LMIC and UMIC respectively). Out of 26 ART studies, 14 report which drug regimes were used, and only one study explicitly reported second line treatment costs. The second cost driver was laboratory cost in LIC and LMIC (14% and 19.5%) whereas it was personnel costs in UMIC (26%). Two studies specified the types of laboratory tests costed, and three studies specifically included above-facility-level personnel costs. Three studies reported detailed PMTCT costs, and two studies reported on pediatric ART. Conclusions There is a paucity of data on the full ART and PMTCT delivery unit costs, in particular for low-and middle-income countries. Heterogeneity in activities costed and insufficient detail regarding

    Nearly a quarter of a million children have acquired HIV, prompting the implementation of new protocols-Option B and B+-for treating HIV+ pregnant women. While efficacy has been demonstrated in randomized trials, there is limited real-world evidence on the impact of these changes. Using longitudinal, routinely collected data we assessed the impact of the adoption of WHO Option B in Rwanda on mother to infant transmission. We used interrupted time series analysis to evaluate the impact of Option B on mother-to-child HIV transmission in Rwanda. Our primary outcome was the proportion of HIV tests in infants with positive results at six weeks of age. We included data for 20 months before and 22 months after the 2010 policy change. Of the 15,830 HIV tests conducted during our study period, 392 tested positive. We found a significant decrease in both the level (-2.08 positive tests per 100 tests conducted, 95% CI: -2.71 to -1.45, p Option B in Rwanda contributed to an immediate decrease in the rate of HIV transmission from mother to child. This suggests other countries may benefit from adopting these WHO guidelines.

    Full Text Available INTRODUCTION: The main route of human immunodeficiency virus (HIV infection in children is from mother to child. The preventive measures established for the Aids Clinical Trial Group protocol 076 (ACTG 076 significantly reduces HIV vertical transmission rates. This study aims to evaluate the implementation of the ACTG 076 protocol in the maternity units of State of Sergipe, Brazilian northeast. METHODS: This is a descriptive, retrospective study with a quantitative approach, with HIV positive women and children exposed, attending a Maternity reference for high-risk pregnancies. Data were obtained from patient records registered in the years 1994 to 2010. RESULTS: Amongst the 110 pregnant women and exposed newborns, the ACTG 076 protocol was fully utilized in only 31.8% of the participants. During the prenatal period, zidovudine (ZDV was taken by 79.1% of the pregnant women. Only 49.1% of HIV seropositive patients used ZDV during delivery. Two (1.8% children were considered infected and 50 (45.5% do not have a conclusive diagnosis to date. CONCLUSIONS: There were significant deficiencies in the prevention of mother-to-child transmission of HIV, including lack of compliance with the three phases of the ACTG 076 protocol; inadequacies in prenatal care; inappropriate mode of delivery and lack of adequate follow up of exposed children.

    Recent achievements in scaling up paediatric antiretroviral therapy (ART) have changed the life of children living with HIV, who now stay healthy and live longer lives. However, as it becomes more of a chronic infection, a range of new problems have begun to arise. These include the disclosure of HIV serostatus to children, adherence to ART, long-term toxicities of antiretroviral drugs and their sexual and reproductive health, which are posing significant challenges to the existing health systems caring for children with HIV with limited resources, experiences and capacities. While intensified efforts and actions to improve care and treatment for these children are needed, it is crucial to accelerate the prevention of mother-to-child transmission (PMTCT) of HIV, which is the main cause of paediatric HIV in the ASEAN region so as to eliminate the fundamental cause of the problem. This report argues that given over 70% of women have access to at least one antenatal care visit in the region and acceptance of HIV testing after receiving counselling on PMTCT could be as high as 90%, there is an opportunity to strengthen PMTCT services and eventually eliminate new paediatric HIV infections in the ASEAN countries.

    Knowledge of HIV/AIDS by pregnant mothers is very important in the prevention of mother to child transmission. This study evaluates the knowledge and perceptions of HIV/AIDS and mother to child transmission among pregnant women attending antenatal clinic at a University Teaching Hospital. Pre-tested questionnaires were interviewer administered to 312 pregnant women randomly selected at the antenatal clinic of the Nnamdi Azikiwe University Teaching Hospital Nnewi. The level of awareness of HIV/AIDS among antenatal mothers was very high (99%) and the main sources of information were radio (44.7%), television (38.8%), and print media (34.0%). Though majority (94.2%) was aware HIV infection can coexist with pregnancy, only 76.9% were aware of mother to child transmission. Transplacental (46.1%), breastfeeding (31.7%), and vaginal delivery (16.3%) were the commonly identified routes of vertical transmission. Surprisingly, eighteen respondents (5.8%) indicated that caesarean section is a possible route of vertical transmission. Though the percentage of HIV/AIDS knowledge is high, the level of knowledge and perceptions of mother to child transmission is inadequate. This suggests the need to scale up health education about mother to child transmission in our health facilities.

    The Chinese government has invested US$140 million annually on prevention of mother-to-child transmission (PMTCT) of HIV. This study evaluates the programme by examining the improvements in programme coverage HIV testing and provision of antiviral drugs along the PMTCT cascade. Data for PMTCT cascade indicators were collected through a comprehensive systematic review of published peer-reviewed English and Chinese literature during 2003-2011. Meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. This study included 113 publications. HIV prevalence among pregnant women in China who accessed antenatal care (ANC) remained below 0.1% during the past decade. HIV testing coverage in pregnant women attending ANC and in HIV-exposed infants at 18 months significantly increased from 62.4% (95% CI 4.7% to 98.2%) and 22.1% (16.3% to 32.3%) in 2003 to 90.3% (88.4% to 91.8%) and 82.8% (66.9% to 99.5%) in 2011 respectively, whereas antiretroviral (ARV) prophylaxis uptake increased from 35.2% (12.2% to 47.3%) and 26.9% (24.3% to 28.9%) to 86.2% (53.2% to 97.2%) and 90.3% (85.5% to 93.7%). HIV vertical transmission rate substantially decreased from 31.8% (25.7% to 38.6%) prior to the programme to 2.3% (1.4% to 3.8%) in 2011. During 2003-2011, among 25,312 (23,995-26,644) infants born to HIV-positive mothers who received ARV prophylaxis, 975 (564-1395) were diagnosed with HIV, corresponding to an average transmission rate of 3.9% (3.2% to 4.6%). However, while including transmissions among HIV-positive pregnant women who were lost along the cascade, the average transmission rate during 2003-2011 was 17.4% (15.8% to 19.0%). PMTCT programmes have reduced HIV mother-to-child transmission in China. Further improvements in the continuum of care remain essential in realising the full potential of the programme.

  2. Increasing adolescent HIV prevalence in Eastern Zimbabwe--evidence of long-term survivors of mother-to-child transmission?

    Directory of Open Access Journals (Sweden)

    Jeffrey W Eaton

    Full Text Available Recent data from the Manicaland HIV/STD Prevention Project, a general-population open HIV cohort study, suggested that between 2004 and 2007 HIV prevalence amongst males aged 15-17 years in eastern Zimbabwe increased from 1.20% to 2.23%, and in females remained unchanged at 2.23% to 2.39%, while prevalence continued to decline in the rest of the adult population. We assess whether the more likely source of the increase in adolescent HIV prevalence is recent sexual HIV acquisition, or the aging of long-term survivors of perinatal HIV acquisition that occurred during the early growth of the epidemic. Using data collected between August 2006 and November 2008, we investigated associations between adolescent HIV and (1 maternal orphanhood and maternal HIV status, (2 reported sexual behaviour, and (3 reporting recurring sickness or chronic illness, suggesting infected adolescents might be in a late stage of HIV infection. HIV-infected adolescent males were more likely to be maternal orphans (RR = 2.97, p<0.001 and both HIV-infected adolescent males and females were more likely to be maternal orphans or have an HIV-infected mother (male RR = 1.83, p<0.001; female RR = 16.6, p<0.001. None of 22 HIV-infected adolescent males and only three of 23 HIV-infected females reported ever having had sex. HIV-infected adolescents were 60% more likely to report illness than HIV-infected young adults. Taken together, all three hypotheses suggest that recent increases in adolescent HIV prevalence in eastern Zimbabwe are more likely attributable to long-term survival of mother-to-child transmission rather than increases in risky sexual behaviour. HIV prevalence in adolescents and young adults cannot be used as a surrogate for recent HIV incidence, and health systems should prepare for increasing numbers of long-term infected adolescents.

    Full Text Available The HIV and AIDS epidemic in South Africa has reached serious proportions. Over 5, 5 million South Africans are infected with HIV (Department of Health, 2004:10. Mother to Child Transmission (MTCT is a well-established mode of HIV transmission and these infections may occur during pregnancy, labour, delivery and breastfeeding. According to the Department of Health (2000:2, breastfeeding constitutes a significant risk of MTCT HIV transmission. Studies in Africa have also shown that breast-feeding increases the risk of MTCT by 12%-43% (Department of Health, 2000:13; Department of Health, 2000:3. Since breastfeeding is a significant and preventable mode of HIV transmission to infants, there is an urgent need to educate, counsel and support women and families to make informed decisions about how best to feed their infants in the context of HTV. To achieve a reduction in MTCT, there is an urgent need to empower women with information on MTCT for informed decision-making. However, cultural factors and the stigma associated with HIV and AIDS might contribute to limited knowledge about MTCT through breastfeeding.

    Full Text Available The Drug Resource Enhancement against AIDS and Malnutrition Program (DREAM gathered professionals in the field of Elimination of HIV-Mother-To-Child Transmission (EMTCT in Maputo in 2013 to discuss obstacles and solutions for the elimination of HIV vertical transmission in sub-Saharan Africa. During this workshop, the benefits of administrating combined antiretroviral therapy (cART to HIV positive women from pregnancy throughout breastfeeding were reviewed. cART is capable of reducing vertical transmission to less than 5% at 24 months of age, as well as maternal mortality and infant mortality in both HIV infected and exposed populations to levels similar to those of uninfected individuals. The challenge for programs targeting eMTCT in developing countries is retention in care and treatment adherence. Both are intrinsically related to the model of care. The drop-out from eMTCT programs before cART initiation ranges from 33%–88% while retention rates at 18–24 months are less than 50%. Comprehensive strategies including peer-to-peer education, social support and laboratory monitoring can reduce refusals to less than 5% and attain retention rates approaching 90%. Several components of the model of care for reduction of HIV-1 MTCT are feasible and implementable in scale-up strategies. A review of this model of care for HIV eMTCT is provided.

    To report the experience of health workers who had played key roles in the early stages of implementing the prevention of mother-to-child HIV transmission services (PMTCT) in Uganda. Interviews were conducted with 15 key informants including counsellors, obstetricians and PMTCT coordinators at the five PMTCT test sites in Uganda to investigate the benefits, challenges and sustainability of the PMTCT programme. Audio-taped interviews were held with each informant between January and June 2003. These were transcribed verbatim and manually analysed using the framework approach. The perceived benefits reported by informants were improvement of general obstetric care, provision of antiretroviral prophylaxis for HIV-positive mothers, staff training and community awareness. The main challenges lay in the reluctance of women to be tested for HIV, incomplete follow-up of participants, non-disclosure of HIV status and difficulties with infant feeding for HIV-positive mothers. Key informants thought that the programme's sustainability depended on maintaining staff morale and numbers, on improving services and providing more resources, particularly antiretroviral therapy for the HIV-positive women and their families. Uganda's experience in piloting the PMTCT programme reflected the many challenges faced by health workers. Potentially resource-sparing strategies such as the 'opt-out' approach to HIV testing required further evaluation.

    Maternal transmission is the most common cause of HCV infection in children. HIV co-infection and high levels of plasma HCV-RNA have been associated with increased HCV transmission rates. We assessed the vertical HCV transmission rate in the HIV-HCV co-infected group of pregnant women on cART. We conducted a retrospective study in a Dutch cohort of HIV-positive pregnant women and their children. We identified co-infected mothers. Results of the HCV tests of the children were obtained. All 21 women were on cART at the time of delivery. We analyzed data of the 24 live-born children at risk for mother-to-child transmission (MTCT) of HCV between 1996 and 2009. HIV-RNA was cell count was 419 cells/μl (290-768). There was no transmission of HIV. The median plasma HCV-RNA in our cohort of 23 non-transmitting deliveries in 21 women was 3.5×10E5 viral eq/ml (IQR 9.6×104-1.5×106veq/mL). One of 24 live-born children was found to be infected with HCV genotype 1. At the time of delivery the maternal plasma HIV-RNA was cell count was 160 cells/μl and maternal plasma HCV-RNA was 4.6×10E6 veq/ml. This amounted to a prevalence of HCV-MTCT of 4%. In this well-defined cohort of HIV-HCV co-infected pregnant women, all treated with cART during pregnancy, a modest rate of vertical HCV transmission was observed. Copyright © 2015 Elsevier B.V.

    This paper builds on critiques that call for a more nuanced and contextualised understanding of conditions that affect HIV prevention by looking at West Papuan women's experiences of prevention of mother-to-child transmission services. Drawing on qualitative, ethnographic research with indigenous women and health workers, the paper demonstrates that women experience poor-quality HIV education and counselling, and that indigenous practices and concerns are largely not addressed by HIV services. We attribute this to a combination of national anti-indigenous and anti-separatist political concerns with donor-led interventions that result in limited localisation and reduced effectiveness of HIV prevention measures. In West Papua, services are needed that enhance cooperation and shared commitment, and that acknowledge and work to overcome existing inequalities, ethnic tensions and discrimination in the health system. Beyond Indonesia, donor-led HIV programmes and interventions need to balance avoidance of politically sensitive issues with complicity in perpetuating health inequalities. Translating global health interventions and donor priorities into locally compelling HIV prevention activities involves more than navigating local cultural and religious beliefs. Programme development and implementation strategies that entail confronting structural questions as well as social hierarchies, cleavages and silences are needed to render more effective services; strategies that are inherently political.

    Full Text Available In 1999, prevention of mother-to-child transmission (pMTCT using antiretrovirals was introduced in the Dominican Republic (DR. Highly active antiretroviral therapy (HAART was introduced for immunosuppressed persons in 2004 and for pMTCT in 2008. To assess progress towards MTCT elimination, data from requisitions for HIV nucleic acid amplification tests for diagnosis of HIV infection in perinatally exposed infants born in the DR from 1999 to 2011 were analyzed. The MTCT rate was 142/1,274 (11.1% in 1999–2008 and 12/302 (4.0% in 2009–2011 (P<.001, with a rate of 154/1,576 (9.8% for both periods combined. This decline was associated with significant increases in the proportions of women who received prenatal HAART (from 12.3% to 67.9% and infants who received exclusive formula feeding (from 76.3% to 86.1% and declines in proportions of women who received no prenatal antiretrovirals (from 31.9% to 12.2% or received only single-dose nevirapine (from 39.5% to 19.5%. In 2007, over 95% of DR pregnant women received prenatal care, HIV testing, and professionally attended delivery. However, only 58% of women in underserved sugarcane plantation communities (2007 and 76% in HIV sentinel surveillance hospitals (2003–2005 received their HIV test results. HIV-MTCT elimination is feasible but persistent lack of access to critical pMTCT measures must be addressed.

    Full Text Available Objective. To evaluate whether the length of time of rupture of membranes (ROM in optimally managed HIV-positive women on highly active antiretroviral therapy (HAART with low viral loads (VL is predictive of the risk of mother to child transmission (MTCT of the human immunodeficiency virus (HIV. Study Methods. A retrospective case series of all HIV-positive women who delivered at two academic tertiary centers in Toronto, Canada from January 2000 to November 2010 was completed. Results. Two hundred and ten HIV-positive women with viral loads <1,000 copies/ml delivered during the study period. VL was undetectable (<50 copies/mL for the majority of the women (167, 80%, and <1,000 copies/mL for all women. Mode of delivery was vaginal in 107 (51% and cesarean in 103 (49%. The median length of time of ROM was 0.63 hours (range 0 to 77.87 hours for the entire group and 2.56 hours (range 0 to 53.90 hours for those who had a vaginal birth. Among women with undetectable VL, 90 (54% had a vaginal birth and 77 (46% had a cesarean birth. Among the women in this cohort there were no cases of MTCT of HIV. Conclusions. There was no association between duration of ROM or mode of delivery and MTCT in this cohort of 210 virally suppressed HIV-positive pregnant women.

    Maternal HIV viral load (VL) drives mother-to-child HIV transmission (MTCT) risk but there are few data from sub-Saharan Africa, where most MTCT occurs. We investigated VL changes during pregnancy and MTCT following antiretroviral therapy (ART) initiation in Cape Town, South Africa. We conducted a prospective study of HIV-infected women initiating ART within routine antenatal services in a primary care setting. VL measurements were taken before ART initiation and up to three more times within 7 days postpartum. Analyses examined VL changes over time, viral suppression (VS) at delivery, and early MTCT based on polymerase chain reaction (PCR) testing up to 8 weeks of age. A total of 620 ART-eligible HIV-infected pregnant women initiated ART, with 2425 VL measurements by delivery (median gestation at initiation, 20 weeks; median pre-ART VL, 4.0 log 10 HIV-1 RNA copies/mL; median time on ART before delivery, 118 days). At delivery, 91% and 73% of women had VL ≤ 1000 and ≤ 50 copies/mL, respectively. VS was strongly predicted by time on therapy and pre-ART VL. The risk of early MTCT was strongly associated with delivery VL, with risks of 0.25, 2.0 and 8.5% among women with VL 1000 copies/mL at delivery, respectively (P pregnancy and with high VL appear substantially less likely to achieve VS and require targeted research and programmatic attention. © 2016 British HIV Association.

    HIV prevalence continues to be high among women of reproductive age in sub-Saharan Africa. In 2007 the HIV prevalence among pregnant women attending antenatal clinics was >20% in the southern African counties of Botswana, Swaziland, South Africa and Lesotho. Mother-to-child transmission (MTCT) of HIV can occur in-utero, intrapartum or postnatally. Without any preventive measure the overall rate of the MTCT of HIV in breastfeeding women could be 25-45%. Prior to the discovery of successful antiretroviral interventions to prevent the MTCT of HIV in sub-Saharan Africa (before 1999), innovative research determined the magnitude of the problem, the impact of the HIV epidemic on mothers and children, and the main risk factors associated with MTCT. Non-antiretroviral interventions conducted before 1999 such as washing the birth canal with antiseptics and antenatal supplementation with vitamin A did not reduce the MTCT of HIV. However, during the period 1999 to present, major successes were made in the prevention of the MTCT of HIV. The use of single-dose nevirapine prophylaxis to the mother and infant reduced the MTCT of HIV to ~12%. Subsequently, longer prophylaxis and combined antiretroviral regimens were shown to be highly effective and very low HIV transmission rates comparable to those in developed countries were reported in some clinical trial settings in sub-Saharan Africa. The future is promising but challenges remain. The current successful intervention modalities are entirely dependent on antiretrovirals and breastfeeding continues to be vital for the survival of the child in the African setting. Reviewing past and present achievements assists in focusing future research and development of prevention programs. Copyright © 2010 Elsevier Inc. All rights reserved.

    Full Text Available Maternal viral load and immune status, timing and route of delivery, viral subtype, and host genetics are known to influence the transmission, acquisition and disease progression of human immunodeficiency virus-1 (HIV-1 infection. This review summarizes the findings from published works on host molecular factors and virus genotypes affecting mother to child transmission (MTCT in Africa and identifies the gaps that need to be addressed in future research. Articles in PubMed, Google and AIDSearch and relevant conference abstracts publications were searched. Accessible articles on host factors and viral genetics impacting the MTCT of HIV, done on African populations till 2015 were downloaded. Forty-six articles were found and accessed; 70% described host genes impacting the transmission. The most studied gene was the CCR5 promoter, followed by the CCR2-64I found to reduce MTCT; then SDF1-3’A shown to have no effect on MTCT and others like the DC-SIGNR, CD4, CCL3 and IP- 10. The HLA class I was most studied and was generally linked to the protective effect on MTCT. Breast milk constituents were associated to protection against MTCT. However, existing studies in Sub Saharan Africa were done just in few countries and some done without control groups. Contradictory results obtained may be due to different genetic background, type of controls, different socio-cultural and economic environment and population size. More studies are thus needed to better understand the mechanism of transmission or prevention.

    Male Involvement (MI) in the Prevention of Mother to Child Transmission (PMTCT) of Human Immunodeficiency Virus (HIV) services is essential in a patriarchal society where men are decision makers of the household. Male partners have a role in the woman's risk of acquiring HIV, uptake of HIV testing and participation in Mother to Child Transmission (MTCT) prevention programmes. Although MI is important for uptake of PMTCT interventions, it remains low in Africa. The purpose of this study was to identify factors that promote and hinder MI in PMTCT services in antenatal care (ANC) services in Blantyre, Malawi. Understanding of the factors that influence MI will assist in developing strategies that will involve men more in the programme thereby improving the uptake of PMTCT and HIV testing and counselling services by women and men respectively. An exploratory qualitative study was conducted from December 2012 to January 2013 at South Lunzu Health Centre (SLHC) in Blantyre, Malawi. It consisted of six face to face Key Informant Interviews (KIIs) with health care workers and four Focus Group discussions (FGDs) with 18 men and 17 pregnant women attending antenatal care at the clinic. The FGDs were divided according to sex and age. All FGDs and KIIs were digitally recorded and simultaneously transcribed and translated verbatim into English. Data were analysed using thematic content analysis. Participants in both FGDs and KIIs identified the following barriers: lack of knowledge of MI in PMTCT, socioeconomic factors, relationship issues, timidity to be seen in a woman's domain, unplanned and or extramarital pregnancies, fear of knowing one's HIV status, unwillingness to be associated with the service, health facility based factors, peer influence and cultural factors. The factors that would potentially promote male involvement were categorized into community, health facility and personal or family level factors. The factors that may hinder or promote MI arise from different

    Prevention of new HIV infections is a critical imperative for South Africa; the prevention of mother-to-child transmission (PMTCT) is one of the most efficacious HIV prevention interventions. Assessment of a PMTCT programme to determine missed opportunities. The Kouga local service area (LSA), bordering Nelson Mandela Bay Municipality (Port Elizabeth) in the Eastern Cape. An assessment was conducted in 2007 before implementing technical support for strengthening the PMTCT programme, including: interviews with 20 PMTCT managers, 4 maternity staff and 27 other health workers on service provision, management, infrastructure, human resources and the health information system; 296 antenatal clinic users on their service perceptions; 70 HIV-positive women on HIV knowledge, infant feeding, coping, support and service perceptions; 8 representatives from community organisations and 101 traditional health practitioners (THPs). Observations were conducted during site visits to health facilities, and the District Health Information System (DHIS) data were reviewed. Staff had high levels of awareness of HIV policies and most had received some relevant training. Nevirapine uptake varied by clinic, with an average of 56%. There were many missed opportunities for PMTCT, with 67% of pregnant women tested for HIV and only 43% of antenatal care attendees tested during a previous pregnancy. Only 6% of HIV-positive women reported support group participation. Reducing missed opportunities for PMTCT requires strengthening of the formal health sector, intersectoral liaison, and greater community support. Priority areas that require strengthening in the formal health sector include HIV counselling and testing; family planning and nutrition counselling; infant follow-up; human resources; and monitoring and evaluation.

    Women's empowerment is associated with engagement in some areas of healthcare, but its role in prevention of mother-to-child HIV transmission (PMTCT) services has not been previously considered. In this secondary analysis, we investigated the association of women's decision-making and uptake of health services for PMTCT. Using data from population-based household surveys, we included women who reported delivery in the 2-year period prior to the survey and were HIV-infected. We measured a woman's self-reported role in decision-making in her own healthcare, making of large purchases, schooling of children, and healthcare for children. For each domain, respondents were categorized as having an "active" or "no active" role. We investigated associations between decision-making and specific steps along the PMTCT cascade: uptake of maternal antiretroviral drugs, uptake of infant HIV prophylaxis, and infant HIV testing. We calculated unadjusted and adjusted odds ratios via logistic regression. From March to December 2011, 344 HIV-infected mothers were surveyed and 276 completed the relevant survey questions. Of these, 190 (69%) took antiretroviral drugs during pregnancy; 175 (64%) of their HIV-exposed infants received antiretroviral prophylaxis; and 160 (58%) had their infant tested for HIV. There was no association between decision-making and maternal or infant antiretroviral drug use. We observed a significant association between decision-making and infant HIV testing in univariate analyses (OR 1.56-1.85; p women who reported an active role in decision-making trended toward a higher likelihood of uptake of infant testing in the PMTCT cascade. Larger studies are needed to evaluate the impact of empowerment initiatives on the PMTCT service utilization overall and infant testing in particular.

    Most countries follow WHO 2010 guidelines for the prevention of mother-to-child transmission (PMTCT) of HIV using either Option A or B for women not yet eligible for antiretroviral therapy (ART). Both of these approaches involve the use of antiretrovirals during pregnancy and breastfeeding. Some countries have adopted a new strategy, Option B+, in which HIV-positive pregnant women are started immediately on ART and continued for life. Option B+ is more costly than Options A or B, but provides additional health benefits. In this article, we estimate the additional costs and effectiveness of Option B+. We developed a deterministic model to simulate births, breastfeeding, and HIV infection in women in four countries, Kenya, Zambia, South Africa, and Vietnam that differ in fertility rate, birth interval, age at first birth, and breastfeeding patterns, but have similar age at HIV infection. We estimated the total PMTCT costs and new child infections under Options A, B, and B+, and measured cost-effectiveness as the incremental PMTCT-related costs per child infection averted. We included adult sexual transmissions averted from ART, the corresponding costs saved, and estimated the total incremental cost per transmission (child and adult) averted. When considering PMTCT-related costs and child infections, Option B+ was the most cost-effective strategy costing between $6000 and $23 000 per infection averted compared with Option A. Option B+ averted more child infections compared with Option B in all four countries and cost less than Option B in Kenya and Zambia. When including adult sexual transmissions averted, Option B+ cost less and averted more infections than Options A and B.

    The current program for prevention of mother-to-child HIV transmission in Thailand recommends a 2-drugs regimen for HIV-infected pregnant women with a CD4 count >200 cells/mm(3). This study assesses the value for money of 3 antiretroviral drugs compared with zidovudine (AZT)+single-dose nevirapine (sd-NVP). A decision tree was constructed to predict costs and outcomes using the governmental perspective for assessing cost-effectiveness of 3-drug regimens: (1) AZT, lamivudine, and efavirenz and (2) AZT, 3TC, and lopinavir/ritonavir, in comparison with the current protocol, AZT+sd-NVP. The 3-drug antiretroviral regimens yield lower costs and better health outcomes compared with AZT+sd-NVP. Although these 3-drug regimens offer higher program costs and health care costs for premature birth, they save money significantly in regard to pediatric HIV treatment and treatment costs for drug resistance in mothers. The 3-drug regimens are cost-saving interventions. The findings from this study were used to support a policy change in the national recommendation. © 2013 APJPH.

    Full Text Available Abstract Viral CCR5 usage is not a predictive marker of mother to child transmission (MTCT of HIV-1. CXCR4-using viral variants are little represented in pregnant women, have an increased although not significant risk of transmission and can be eventually also detected in the neonates. Genetic polymorphisms are more frequently of relevance in the child than in the mother. However, specific tissues as the placenta or the intestine, which are involved in the prevalent routes of infection in MTCT, may play an important role of selective barriers. The virus phenotype of the infected children, like that of adults, can evolve from R5 to CXCR4-using phenotype or remain R5 despite clinical progression to overt immune deficiency. The refined classification of R5 viruses into R5narrow and R5broad resolves the enigma of the R5 phenotype being associated with the state of immune deficiency. Studies are needed to address more in specific the relevance of these factors in HIV-1 MTCT and pediatric infection of non-B subtypes.

    In India, programme for prevention of mother-to-child transmission (PMTCT) of HIV is primarily implemented through public health system. State AIDS Control Societies (SACSs) encourage private hospitals to set up integrated counselling and testing centres (ICTCs). However, private hospitals of Delhi did not set up ICTCs. Consequently, there is no information on PMTCT interventions in private hospitals of Delhi. This study was undertaken by Delhi SACS during March 2013 through September 2013 to assess status of implementation of PMTCT programme in various private hospitals of Delhi to assist programme managers in framing national policy to facilitate uniform implementation of National PMTCT guidelines. Out of total 575 private hospitals registered with Government of Delhi, 336 (58.4%) catering to pregnant women were identified. About 100 private hospitals with facility of antenatal care, vaginal/caesarean delivery and postnatal care and minimum 10 indoor beds were selected for study. Study sample comprised of large corporate hospitals (≥100 beds; n = 29), medium-sized hospitals (25 to women tested, 52 (0.14%) were detected HIV-positive. However, against National Policy, HIV testing was done without pre/post-test counselling/or consent of women, no PMTCT protocol existed, delivery of HIV-positive women was not undertaken and no efforts were made to link HIV-positive women to antiretroviral treatment. Major intervention observed was medical termination of pregnancy, which indicates lack of awareness in private hospitals about available interventions under national programme. The role of private hospitals in management of HIV in pregnant women must be recognized and mainstreamed in HIV control efforts. There is an urgent need for capacity building of private health care providers to improve standards of practice. National AIDS Control Organization may consider establishing linkages or adopting model developed by some countries with generalized epidemic for delivering

    A lot of challenges face the current efforts at reducing Mother to Child transmission of HIV infection (MTCT) in Sub Saharan Africa due to limited access to Highly active antiretroviral therapy (HAART) and breast feeding practices. A regular review of progress is necessary in order to identify areas of need. This is a one year prospective descriptive study of seven hundred and twenty six mother-infant pairs managed in the PMTCT programme in Nnamdi Azikiwe University Teaching Hospital, Nnewi Southeast Nigeria. The babies HIV status was tested with PCR for HIV DNA while the mothers provided information on infant feeding pattern and the use of antiretroviral (ARV) drugs including prophylaxis for the baby. Information was augmented from the antenatal records. The transmission rate was 2.8% for mothers, who were on HAART, did not breastfeed and whose babies received ARV prophylactic therapy. But for mothers who did not receive HAART, did breastfeed and whose babies did not received ARV prophylactic therapy, the transmission rate was 37.5%. When both the mother and child received ARV drugs, the transmission rate was significantly lower in those who did not breastfeed (2.8%) than in those who breastfed (12.5%)(P < 0.001). When both the mother and child did not receive ARV drugs, the transmission rate significantly lower in those who did not breastfeed (21.1%)than in those who breastfed (37.5%) (P < 0.02). The use of HAART in PMTCT programme in the under resourced areas can achieve similar success rates to that in the industrialized countries. Breastfeeding reduces the efficacy achieved by the use of ARV drugs. Provision of wider access to HAART as well as adequate counselling and support for safer infant feeding practices is recommended.

    The success of prevention of mother-to-child transmission of HIV (PMTCT) is dependent upon high retention of mother-infant pairs within these programmes. This is a systematic review to evaluate the effectiveness of interventions that aim to improve PMTCT service delivery and promote retention throughout the PMTCT steps. Selected databases were searched for studies published in English (up to September 2015). Outcomes of interest included antiretroviral (ARV) drugs or antiretroviral therapy (ART) initiation among HIV-positive pregnant and/or breastfeeding women and their infants, retention into PMTCT programs, the uptake of early infant diagnosis (EID) of HIV and infant HIV status. Risk ratios and random-effect meta-analysis were used in the analysis. Interventions assessed in the 34 identified studies included male partner involvement in PMTCT, peer mentoring, the use of community health workers (CHWs), mobile phone-based reminders, conditional cash transfer, training of midwives, integration of PMTCT services and enhanced referral. Five studies (two randomized) that evaluated mobile phone-based interventions showed a statistically significant increase (pooled RR 1.18; 95% CI 1.05 to 1.32, I(2)=83%) in uptake of EID of HIV at around six weeks postpartum. Male partner involvement in PMTCT was associated with reductions in infant HIV transmission (pooled RR 0.61; 95% CI 0.39 to 0.94, I(2)=0%) in four studies (one randomized). Four studies (three randomized) that were grounded on psychological interventions reported non-significant results (pooled RR 1.01; 95% CI 0.93 to 1.09, I(2)=69%) in increasing ARV/ART uptake among HIV-positive pregnant and/or breastfeeding women and infant HIV testing (pooled RR 1.00; 95% CI 0.94 to 1.07, I(2)=45%). The effect of the other interventions on the effectiveness of improving PMTCT uptake was unclear. Heterogeneity of interventions limits these findings. Our findings indicate that mobile phone-based reminders may increase the uptake

We used a combination of approaches to health systems strengthening to reduce transmission of HIV from mother to infant in a multi-facility public health system in South Africa.All primary care sites and specialized birthing centers in a resource constrained sub-district of Cape Metro District, South Africa, were enrolled in a quality improvement (QI programme. All pregnant women receiving antenatal, intrapartum and postnatal infant care in the sub-district between January 2006 and March 2009 were included in the intervention that had a prototype-innovation phase and a rapid spread phase. System changes were introduced to help frontline healthcare workers to identify and improve performance gaps at each step of the PMTCT pathway. Improvement was facilitated and spread through the use of a Breakthrough Series Collaborative that accelerated learning and the spread of successful changes. Protocol changes and additional resources were introduced by provincial and municipal government. The proportion of HIV-exposed infants testing positive declined from 7.6% to 5%. Key intermediate PMTCT processes improved (antenatal AZT increased from 74% to 86%, PMTCT clients on HAART at the time of labour increased from 10% to 25%, intrapartum AZT increased from 43% to 84%, and postnatal HIV testing from 79% to 95% compared to baseline.System improvement methods, protocol changes and addition/reallocation of resources contributed to improved PMTCT processes and outcomes in a resource constrained setting. The intervention requires a clear design, leadership buy-in, building local capacity to use systems improvement methods, and a reliable data system. A systems improvement approach offers a much needed approach to rapidly improve under

    The Joint United Nations Programme on HIV and AIDS proposed to reduce the vertical transmission of HIV from ∼72,200 to ∼8300 newly infected children by 2015 in South Africa (SA). However, cultural, infrastructural, and socio-economic barriers hinder the implementation of the prevention of mother-to-child transmission (PMTCT) protocol, and research on potential solutions to address these barriers in rural areas is particularly limited. This study sought to identify challenges and solutions to the implementation, uptake, and sustainability of the PMTCT protocol in rural SA. Forty-eight qualitative interviews, 12 focus groups discussions (n = 75), and one two-day workshop (n = 32 participants) were conducted with district directors, clinic leaders, staff, and patients from 12 rural clinics. The delivery and uptake of the PMTCT protocol was evaluated using the Consolidated Framework for Implementation Research (CFIR); 15 themes associated with challenges and solutions emerged. Intervention characteristics themes included PMTCT training and HIV serostatus disclosure. Outer-setting themes included facility space, health record management, and staff shortage; inner-setting themes included supply use and availability, staff-patient relationship, and transportation and scheduling. Themes related to characteristics of individuals included staff relationships, initial antenatal care visit, adherence, and culture and stigma. Implementation process themes included patient education, test results delivery, and male involvement. Significant gaps in care were identified in rural areas. Information obtained from participants using the CFIR framework provided valuable insights into solutions to barriers to PMTCT implementation. Continuously assessing and correcting PMTCT protocol implementation, uptake and sustainability appear merited to maximize HIV prevention.

    Introduction Prevention of mother-to-child transmission (PMTCT) has the potential to eliminate new HIV infections among infants. Yet in many parts of sub-Saharan Africa, PMTCT coverage remains low, leading to unacceptably high rates of morbidity among mothers and new infections among infants. Intimate partner violence (IPV) may be a structural driver of poor PMTCT uptake, but has received little attention in the literature to date. Methods We conducted qualitative research in three Johannesburg antenatal clinics to understand the links between IPV and HIV-related health of pregnant women. We held focus group discussions with pregnant women (n=13) alongside qualitative interviews with health care providers (n=10), district health managers (n=10) and pregnant abused women (n=5). Data were analysed in Nvivo10 using a team-based approach to thematic coding. Findings We found qualitative evidence of strong bidirectional links between IPV and HIV among pregnant women. HIV diagnosis during pregnancy, and subsequent partner disclosure, were noted as a common trigger of IPV. Disclosure leads to violence because it causes relationship conflict, usually related to perceived infidelity and the notion that women are “bringing” the disease into the relationship. IPV worsened HIV-related health through poor PMTCT adherence, since taking medication or accessing health services might unintentionally alert male partners of the women's HIV status. IPV also impacted on HIV-related health via mental health, as women described feeling depressed and anxious due to the violence. IPV led to secondary HIV risk as women experienced forced sex, often with little power to negotiate condom use. Pregnant women described staying silent about condom negotiation in order to stay physically safe during pregnancy. Conclusions IPV is a crucial issue in the lives of pregnant women and has bidirectional links with HIV-related health. IPV may worsen access to PMTCT and secondary prevention behaviours

    To estimate the cost-effectiveness of prevention of mother-to-child transmission (MTCT) of HIV with lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') compared with ART during pregnancy or breastfeeding only unless clinically indicated ('Option B'). Mathematical modelling study of first and second pregnancy, informed by data from the Malawi Option B+ programme. Individual-based simulation model. We simulated cohorts of 10 000 women and their infants during two subsequent pregnancies, including the breastfeeding period, with either Option B+ or B. We parameterized the model with data from the literature and by analysing programmatic data. We compared total costs of antenatal and postnatal care, and lifetime costs and disability-adjusted life-years of the infected infants between Option B+ and Option B. During the first pregnancy, 15% of the infants born to HIV-infected mothers acquired the infection. With Option B+, 39% of the women were on ART at the beginning of the second pregnancy, compared with 18% with Option B. For second pregnancies, the rates MTCT were 11.3% with Option B+ and 12.3% with Option B. The incremental cost-effectiveness ratio comparing the two options ranged between about US$ 500 and US$ 1300 per DALY averted. Option B+ prevents more vertical transmissions of HIV than Option B, mainly because more women are already on ART at the beginning of the next pregnancy. Option B+ is a cost-effective strategy for PMTCT if the total future costs and lost lifetime of the infected infants are taken into account.

    Since 2012, the WHO recommends Option B+ for the prevention of mother-to-child transmission of HIV. This approach entails the initiation of lifelong antiretroviral therapy in all HIV-positive pregnant women, also implying protection during breastfeeding for 12 months or longer. Research on long-term adherence to Option B+ throughout breastfeeding is scarce to date. Therefore, we conducted a prospective observational cohort study in Fort Portal, Western Uganda, to assess adherence to Option B+ until 18 months postpartum. In 2013, we recruited 67 HIV-positive, Option B+ enrolled women six weeks after giving birth and scheduled them for follow-up study visits after six, twelve and 18 months. Two adherence measures, self-reported drug intake and amount of drug refill visits, were combined to define adherence, and were assessed together with feeding information at all study visits. At six months postpartum, 51% of the enrolled women were considered to be adherent. Until twelve and 18 months postpartum, adherence for the respective follow-up interval decreased to 19% and 20.5% respectively. No woman was completely adherent until 18 months. At the same time, 76.5% of the women breastfed for ≥12 months. Drug adherence was associated with younger age (ptravel costs (p = 0.02), and lower number of previous deliveries (p = 0.04). Long-term adherence to Option B+ seems to be challenging. Considering that in our cohort, prolonged breastfeeding until ≥12 months was widely applied while postpartum adherence until the end of breastfeeding was poor, a potential risk of postpartum vertical transmission needs to be taken seriously into account for Option B+ implementation.

    Male participation in the prevention of mother-to-child transmission (PMTCT) of HIV has been determined as one of the key factors in sub-Saharan African countries, but its realization is challenging because of male-related and institutional factors. The purpose of this study is two-fold: first, we explored the views of Luba-Kasai men, living in Zambia in the Lusaka Province, on the factors that encourage, inconvenience or inhibit them in accompanying their wives to the antenatal clinic and their ideas to improve their experience. Secondly, the study considered their knowledge of the PMTCT program and how such knowledge conformed to the Zambian National Protocol Guidelines Integrated PMTCT of HIV /: AIDS. Twenty-one interviews were analyzed using qualitative inductive content analysis. The National Protocol Guidelines Integrated PMTCT of HIV/AIDS were analyzed using the deductive content analysis. The encouraging factors that emerged were involvement in the program, the time of delivery, love and care, and also the suspicion of corruption. The inconveniencing factors were the arrangements and working culture of the clinic, together with stigma and guilt. A lack of motivation, fear of death, socioeconomic circumstances and again the arrangements and working culture at the clinic were held as inhibiting factors. The ideas to remove inconvenient factors were maintaining a spiritual outlook on life, education, interaction, a good mood and a sense of meaningfulness. Considering such male views and paying attention to minorities in the development of national PMTCT of HIV Programs may enhance male participation in the process. © The Author (2014).

    In sub-Saharan Africa (SSA), male partners are rarely present during prevention of mother-to-child transmission (PMTCT) services. This systematic review aims to synthesize, from a male perspective, male partners' perceived roles, barriers and enablers of their involvement in PMTCT, and highlights persisting gaps. We carried out a systematic search of papers published between 2002 and 2013 in English on Google Scholar and PubMed using the following terms: men, male partners, husbands, couples, involvement, participation, Antenatal Care (ANC), PMTCT, SSA countries, HIV Voluntary Counseling and Testing and disclosure. A total of 28 qualitative and quantitative original studies from 10 SSA countries were included. Men's perceived role was addressed in 28% (8/28) of the studies. Their role to provide money for ANC/PMTCT fees was stated in 62.5% (5/8) of the studies. For other men, the financial responsibilities seemed to be used as an excuse for not participating. Barriers were cited in 85.7% (24/28) of the studies and included socioeconomic factors, gender role, cultural beliefs, male unfriendly ANC/PMTCT services and providers' abusive attitudes toward men. About 64% (18/28) of the studies reported enablers such as: older age, higher education, being employed, trustful monogamous marriages and providers' politeness. In conclusion, comprehensive PMTCT policies that are socially and culturally sensitive to both women and men need to be developed.

    Objective: We estimate facility-level average annual costs per client along the HIV testing and counselling (HTC) and prevention of mother-to-child transmission (PMTCT) service cascades. Design: Data collected covered the period 2011–2012 in 230 HTC and 212 PMTCT facilities in Kenya, Rwanda, South Africa, and Zambia. Methods: Input quantities and unit prices were collected, as were output data. Annual economic costs were estimated from the service providers’ perspective using micro-costing. Average annual costs per client in 2013 United States dollars (US$) were estimated along the service cascades. Results: For HTC, average cost per client tested ranged from US$5 (SD US$7) in Rwanda to US$31 (SD US$24) in South Africa, whereas average cost per client diagnosed as HIV-positive ranged from US$122 (SD US$119) in Zambia to US$1367 (SD US$2093) in Rwanda. For PMTCT, average cost per client tested ranged from US$18 (SD US$20) in Rwanda to US$89 (SD US$56) in South Africa; average cost per client diagnosed as HIV-positive ranged from US$567 (SD US$417) in Zambia to US$2021 (SD US$3210) in Rwanda; average cost per client on antiretroviral prophylaxis ranged from US$704 (SD US$610) in South Africa to US$2314 (SD US$3204) in Rwanda; and average cost per infant on nevirapine ranged from US$888 (SD US$884) in South Africa to US$2359 (SD US$3257) in Rwanda. Conclusion: We found important differences in unit costs along the HTC and PMTCT service cascades within and between countries suggesting that more efficient delivery of these services is possible.

    Background. In 2010, the World Health Organization (WHO) released revised guidelines for prevention of mother-to-child human immunodeficiency virus (HIV) transmission (PMTCT). We projected clinical impacts, costs, and cost-effectiveness of WHO-recommended PMTCT strategies in Zimbabwe. Methods. We used Zimbabwean data in a validated computer model to simulate a cohort of pregnant, HIV-infected women (mean age, 24 years; mean CD4 count, 451 cells/µL; subsequent 18 months of breastfeeding). We simulated guideline-concordant care for 4 PMTCT regimens: single-dose nevirapine (sdNVP); WHO-recommended Option A, WHO-recommended Option B, and Option B+ (lifelong maternal 3-drug antiretroviral therapy regardless of CD4). Outcomes included maternal and infant life expectancy (LE) and lifetime healthcare costs (2008 US dollars [USD]). Incremental cost-effectiveness ratios (ICERs, in USD per year of life saved [YLS]) were calculated from combined (maternal + infant) discounted costs and LE. Results. Replacing sdNVP with Option A increased combined maternal and infant LE from 36.97 to 37.89 years and would reduce lifetime costs from $5760 to $5710 per mother–infant pair. Compared with Option A, Option B further improved LE (38.32 years), and saved money within 4 years after delivery ($5630 per mother–infant pair). Option B+ (LE, 39.04 years; lifetime cost, $6620 per mother–infant pair) improved maternal and infant health, with an ICER of $1370 per YLS compared with Option B. Conclusions. Replacing sdNVP with Option A or Option B will improve maternal and infant outcomes and save money; Option B increases health benefits and decreases costs compared with Option A. Option B+ further improves maternal outcomes, with an ICER (compared with Option B) similar to many current HIV-related healthcare interventions. PMID:23204035

    Full Text Available Abstract Background Prevention of mother-to-child transmission has been considered as not a simple intervention but a comprehensive set of interventions requiring capable health workers. Viet Nam's extensive health care system reaches the village level, but still HIV-infected mothers and children have received inadequate health care services for prevention of mother-to-child transmission. We report here the health workers' perceptions on factors that lead to their failure to give good quality prevention of mother-to-child transmission services. Methods Semistructured interviews with 53 health workers and unstructured observations in nine health facilities in Hanoi were conducted. Selection of respondents was based on their function, position and experience in the development or implementation of prevention of mother-to-child transmission policies/programmes. Results Factors that lead to health workers' failure to give good quality services for prevention of mother-to-child transmission include their own fear of HIV infection; lack of knowledge on HIV and counselling skills; or high workloads and lack of staff; unavailability of HIV testing at commune level; shortage of antiretroviral drugs; and lack of operational guidelines. A negative attitude during counselling and provision of care, treating in a separate area and avoidance of providing service at all were seen by health workers as the result of fear of being infected, as well as distrust towards almost all HIV-infected patients because of the prevailing association with antisocial behaviours. Additionally, the fragmentation of the health care system into specialized vertical pillars, including a vertical programme for HIV/AIDS, is a major obstacle to providing a continuum of care. Conclusion Many hospital staff were not being able to provide good care or were even unwilling to provide appropriate care for HIV-positive pregnant women The study suggests that the quality of prevention of

    Full Text Available Abstract Background It has been estimated that 430,000 children under 15 years of age were newly infected with HIV in 2008, and more than 71% are living in sub-Saharan Africa. In the absence of intervention to prevent mother-to-child transmission, 30-45% of infants born to HIV-positive mothers in developing countries become infected during pregnancy, delivery and breastfeeding. The aim of this study was to assess infant feeding practice and associated factors of HIV positive mothers attending prevention of mother to child transmission and antiretroviral therapy clinics of Northwest Ethiopia. Methods Institution based cross sectional study was conducted from January to May 2011 among all HIV positive mothers with less than two years old child attending prevention of mother to child transmission and antiretroviral therapy clinics in Gondar Town health institutions. A structured pre-tested questionnaire using interview technique was used for data collection. The data was entered and analyzed using SPSS version 16 statistical package. Results A total of 209 HIV positive mothers were included in the study. Of these, 187 (89.5% had followed the recommended way of infant feeding practice while significant percentage (10.5% had practiced mixed breast feeding. In multivariate analysis, disclosure of HIV status with their spouse, insufficient breast milk and occupational status were found to be independently associated (p-value of Conclusions Higher proportion of respondents used the recommended way of infant feeding practice by WHO as well as by Ethiopian Ministry of Health. However, mixed feeding in the first 6 months of age, an undesirable practice in infant feeding, were reported in this study. Infant feeding education that is aligned to national policy should be strengthened in primary health care, particularly in situations where prevention of mother to child transmission of HIV is prioritized.

    Full Text Available Abstract Background In 2006 the World Health Organization described the status of prevention of mother to child transmission (PMTCT service implementation as unacceptable, with an urgent need for a renewed public health approach to improve access. For PMTCT to be effective it needs to be accessible, acceptable and affordable; however research in Africa into accessibility, uptake and acceptability of PMTCT services has been predominately urban based and usually focusing on women who deliver in hospitals. The importance of involving other community members to strengthen both PMTCT uptake and adherence, and to support women emotionally, has been advocated. Urban men's and rural traditional birth attendants' (TBAs involvement have improved uptake of HIV testing and of nevirapine. Methods A qualitative study was carried out in a rural district of Malawi's central region to explore the views about and perceptions of PMTCT antiretroviral treatment. Semi-structured interviews and focus group discussions were held with antenatal and postnatal women, fathers, grandmothers, TBAs, community leaders and PMTCT health workers. Results Two broad themes of findings emerged: those that relate to the hospital PMTCT service, and those that relate to the community. Trust in the hospital was strong, but distance, transport costs and perceived harsh, threatening health worker attitudes were barriers to access. Grandmothers were perceived to have influence on the management of labour, unlike fathers, but both were suggested as key people to ensure that babies are brought to the hospital for nevirapine syrup. TBAs were seen as powerful, local, and important community members, but some as uneducated. Conclusion PMTCT was seen as a community issue in which more than the mother alone can be involved. To support access to PMTCT, especially for rural women, there is need for further innovation and implementation research on involving TBAs in some aspects of PMTCT services

    Full Text Available Abstract Background The HIV epidemic in Russia has increasingly involved reproductive-aged women, which may increase perinatal HIV transmission. Methods Standard HIV case-reporting and enhanced perinatal HIV surveillance systems were used for prospective assessment of HIV-infected women giving birth in St. Petersburg, Russia, during 2004-2008. Trends in social, perinatal, and clinical factors influencing mother-to-child HIV transmission stratified by history of injection drug use, and rates of perinatal HIV transmission were assessed using two-sided χ2 or Cochran-Armitage tests. Results Among HIV-infected women who gave birth, the proportion of women who self-reported ever using injection drugs (IDUs decreased from 62% in 2004 to 41% in 2008 (P P P P for trend Conclusions Reduced proportion of IDUs and improved clinical services among HIV-infected women giving birth were accompanied by decreased perinatal HIV transmission, which can be further reduced by increasing outreach and HIV testing of women before and during pregnancy.

  11. Mother-to-Child HIV-1 Transmission Events Are Differentially Impacted by Breast Milk and Its Components from HIV-1-Infected Women.

    Full Text Available Breast milk is a vehicle of infection and source of protection in post-natal mother-to-child HIV-1 transmission (MTCT. Understanding the mechanism by which breast milk limits vertical transmission will provide critical insight into the design of preventive and therapeutic approaches to interrupt HIV-1 mucosal transmission. However, characterization of the inhibitory activity of breast milk in human intestinal mucosa, the portal of entry in postnatal MTCT, has been constrained by the limited availability of primary mucosal target cells and tissues to recapitulate mucosal transmission ex vivo. Here, we characterized the impact of skimmed breast milk, breast milk antibodies (Igs and non-Ig components from HIV-1-infected Ugandan women on the major events of HIV-1 mucosal transmission using primary human intestinal cells and tissues. HIV-1-specific IgG antibodies and non-Ig components in breast milk inhibited the uptake of Ugandan HIV-1 isolates by primary human intestinal epithelial cells, viral replication in and transport of HIV-1- bearing dendritic cells through the human intestinal mucosa. Breast milk HIV-1-specific IgG and IgA, as well as innate factors, blocked the uptake and transport of HIV-1 through intestinal mucosa. Thus, breast milk components have distinct and complementary effects in reducing HIV-1 uptake, transport through and replication in the intestinal mucosa and, therefore, likely contribute to preventing postnatal HIV-1 transmission. Our data suggests that a successful preventive or therapeutic approach would require multiple immune factors acting at multiple steps in the HIV-1 mucosal transmission process.

    We estimated mortality rate and predictors of death in children and adolescents who acquired HIV through mother-to-child transmission in Paraguay. In 2000-2014, we conducted a cohort study among children and adolescents aged  9 g/dL (HR 2.27, 95% CI 1.01-5.10). The mortality of HIV-infected children and adolescents in Paraguay is high, and anemia is associated with mortality. Improving prenatal screening to find cases earlier and improving pediatric follow-up are needed.

    Three decades since the first HIV-1 infected patients in Rwanda were identified in 1983; the Acquired Immunodeficiency Syndrome epidemic has had a devastating history and is still a major public health challenge in the country. This study was aimed at assessing socioeconomic, clinical and biological risk factors for mother - to - child transmission of HIV- in Muhima health centre (Kigali/Rwanda). The prospective cohort study was conducted at Muhima Health centre (Kigali/Rwanda).During the study period (May 2007 - April 2010), of 8,669 pregnant women who attended antenatal visits and screened for HIV-1, 736 tested HIV-1 positive and among them 700 were eligible study participants. Hemoglobin, CD4 count and viral load tests were performed for participant mothers and HIV-1 testing using DNA PCR technique for infants.Follow up data for eligible mother-infant pairs were obtained from women themselves and log books in Muhima health centre and maternity, using a structured questionnaire.Predictors of mother-to-child transmission of HIV-1 were assessed by multivariable logistic regression analysis. Among the 679 exposed and followed-up infants, HIV-1 status was significantly associated with disclosure of HIV status to partner both at 6 weeks of age (non-disclosure of HIV status, adjusted odds ratio [AOR] 4.68, CI 1.39 to 15.77, p  = 1000 copies/ml, AOR 7.30, CI 2.65 to 20.08, p  = 1000 copies/ml, AOR 4.60, CI 1.84 to 11.49, p < 0.01, compared to <1000 copies/ml). In this study, the most relevant factors independently associated with increased risk of mother - to - child transmission of HIV-1 included non-disclosure of HIV status to partner and high HIV-1 RNA. Members of this cohort also showed socioeconomic inequalities, with unmarried status carrying higher risk of undisclosed HIV status. The monitoring of maternal HIV-1 RNA level might be considered as a routinely used test to assess the risk of transmission with the goal of achieving viral suppression as

    Full Text Available Abstract Background In the absence of reliable data, antenatal HIV surveillance has been used to monitor the HIV epidemic since the late 1980s. Currently, routine data from Prevention of Mother-to-child HIV transmission (PMTCT programmes are increasingly available. Evaluating whether the PMTCT programme reports provide comparable HIV prevalence estimates with the antenatal surveillance reports is important. In this study, we compared HIV prevalence estimates from routine PMTCT programme and antenatal surveillance in Addis Ababa with the aim to come up with evidence based recommendation. Methods Summary data were collected from PMTCT programmes and antenatal surveillance reports within the catchment of Addis Ababa. The PMTCT programme data were obtained from routine monthly reports from 2004 to 2009 and from published antenatal HIV surveillance reports from 2003 to 2009. Data were analysed using descriptive statistics. Results In Addis Ababa, PMTCT sites had increased from six in 2004 to 54 in 2009. The site expansion was accompanied by an increased number of women testing. There were marked increases in the rate of HIV testing following the introduction of routine opt-out HIV testing approach. Paralleling these increases, the HIV prevalence showed a steady decline from 10.0% in 2004 to 4.5% in 2009. There were five antenatal surveillance sites from 2003 to 2007 in Addis Ababa and they increased to seven by 2009. Four rounds of surveillance data from five sites showed a declining trend in HIV prevalence over the years. The overall antenatal surveillance data also showed that the HIV prevalence among antenatal attendees had declined from 12.4% in 2003 to 5.5% in 2009. The HIV prevalence estimates from PMTCT programme were 6.2% and 4.5% and from antenatal surveillance 6.1 and 5.5% in 2008 and 2009 respectively. Conclusions There were consistent HIV prevalence estimates from PMTCT programme and from antenatal surveillance reports. Both data sources

    Full Text Available We describe the impact of strategies to reduce HIV-1 vertical transmission on a cohort of pregnant women and evaluate toxicity related to antiretroviral (ARV therapy and prevalence of birth defects. In this observational, retrospective, longitudinal and descriptive study, we have reviewed the data base and clinical charts from a cohort of 351 pregnant women with HIV infection admitted to a public hospital in Buenos Aires from April 1994 to August 2003. Eighty percent of women were infected by sexual transmission. Diagnosis of HIV infection was performed before pregnancy in 38.5% of cases; 241 patients received some kind of ARV therapy, combined therapy was administered in 123 of cases. The overall transmission rate was 9.6%, and antiretroviral therapy was the most significant factor associated with the transmission rate. HIV transmission odds were 0.04 for any ARV treatment versus no therapy. No cases of HIV transmission were observed among women given combination ARV therapy. More prevalent secondary effects associated to ARV therapy were anemia, hypercholesterolemia, increase of ALP and hypertrigliceridemia. In conclusion, antiretroviral therapy, particularly combined ARV therapy, irrespective of type of delivery, was associated with a reduced risk of HIV transmission without an increase in toxicity or incidence of congenital abnormalities in the short-term.En este estudio se describe el impacto de las estrategias implementadas para reducir la trasmisión vertical de HIV en una cohorte de mujeres embarazadas.

    Full Text Available Loss-to-follow-up (LTFU throughout the Prevention of Mother-To-Child Transmission (PMTCT cascade remains one of the major threats to the success of PMTCT programs. In this study, we aimed to determine the mother-to-child transmission rate in a programmatic setting and to determine factors associated with LTFU among enrolled mothers and unfavorable outcomes among HIV-exposed babies which includes being HIV positive, death and LTFU.A retrospective cohort study reviewing routinely collected data in an Integrated HIV care program, Mandalay, Myanmar in June 2016.LTFU means mother/infant missing appointed visit for more than three months.Of 678 pregnant women enrolled in PMTCT program between March 2011 and June 2014, one stillbirth and 607 live births were recorded in this cohort. Of 457 HIV-exposed babies with HIV-test recorded at the end of the intervention, nine (2% were HIV-positive. Pregnant women's and exposed-babies' LTFU rate was 7 per 1000 person-years, and 10 per 1000 person-years respectively. PMTCT option B protocol was found to be significantly associate with maternal LTFU [adjusted Hazard Ratio (aHR 95% CI: 3.52 (1.38-8.96] when compare to mothers receiving option B+/lifelong antiretroviral therapy (ART.

    Retention of patients in long term care and adherence to treatment regimens are a constant challenge for HIV, prevention of mother to child transmission of HIV (PMTCT), and TB programmes in sub-Saharan Africa. This study describes the implementation and outcomes of an active defaulter tracing system used to reduce loss to follow-up (LTFU) among HIV, PMTCT, TB, and HIV/TB co-infected patients receiving treatment at three Médecins Sans Frontières clinics in the informal settlement of Kibera, Nairobi, Kenya. Patients are routinely contacted by a social worker via telephone, in-person visit, or both very soon after they miss an appointment. Patient outcomes identified through 1066 tracing activities conducted between 1 April 2008 and 31 March 2009 included: 59.4% returned to the clinic, 9.0% unable to return to clinic, 6.3% died, 4.7% refused to return to clinic, 4.5% went to a different clinic, and 0.8% were hospitalized. Fifteen percent of patients identified for tracing could not be contacted. LTFU among all HIV patients decreased from 21.2% in 2006 to 11.5% in 2009. An active defaulter tracing system is feasible in a resource poor setting, solicits feedback from patients, retains a mobile population of patients in care, and reduces LTFU among HIV, PMTCT, and TB patients.

    In this study, we assessed male partner testing and the serodiscordance rate among pregnant women and their partners in the prevention of mother-to-child transmission (PMTCT) programme in Nigeria. We conducted a retrospective analysis of the consolidated national health sector PMTCT data over a five-year period (2012-2016). Over the period, a total of 11,833,062 pregnant women were tested for HIV with a positivity rate of 2.2%. About 266,188 (2.2%) of sexual partners of pregnant women who presented at PMTCT clinics had an HIV test within the period. The uptake of male partner testing varied across the years, ranging from 22,269 (1.7%) in 2012 to 90,603 (2.9%) in 2014 (χ 2 for trend = 1320; p HIV-negative pregnant women who tested was higher than the proportion of partners of HIV-positive pregnant women (81% versus 19%, respectively).

    Prevention of mother-to-child transmission (PMTCT) depends critically on HIV-positive women's adherence to antiretroviral drugs during and after pregnancy. Adherence among pregnant and breastfeeding women remains a challenge across sub-Saharan Africa. Power dynamics within couples, such as intimate partner violence, has largely been neglected in research regarding PMTCT adherence. This study aims to determine if there is a relationship between intimate partner violence and non-adherence to PMTCT. In 2014, using a verbally administered cross-sectional survey at a large public health clinic in Lusaka, Zambia, 320 HIV-positive postpartum women, who were currently married or living with a man, provided information on their drug adherence during and after pregnancy, as well as relationship dynamics. Adherence was defined as the woman reporting she took or gave to the infant at least 80% of prescribed medication doses. Experiencing intimate partner violence was associated with decreased odds of adherence to PMTCT during and after pregnancy. Different forms of violence affected PMTCT adherence differentially. Physical violence had a less pronounced effect on non-adherence than emotional and sexual violence. A dose-response relationship between intimate partner violence and non-adherence was also observed. Intimate partner violence is associated with non-adherence to PMTCT during and after pregnancy, which deserves increased attention in the effort to eliminate mother-to-child transmission of HIV.

    Objective: To estimate HIV seroprevalence among pregnant women with syphilis and evaluate the influence of syphilis infection on mother-to-child-transmission (MTCT) of HIV by meta-analysis. Methods: We conducted a systematic literature search for 1 678 articles related to maternal syphilis and HIV infection published until October 1 st 2015 using the PubMed, Web of Science, Chinese Web of Knowledge, Wanfang, Weipu, and SinoMed databases and evaluated the quality of each papers using the STROBE checklist, and the keywords were " pregnant women/maternal/pregnancy" , "syphilis/AIDS" , "HIV/human immunodeficiency virus" , "mother- to-child transimission/vertical transmission" . Excluding studies with the special subgroups of HIV-positive pregnant women as the research objects, review or meeting abstract, impossibility of full-text acquisition, sample size HIV seroprevalence among pregnant women with syphilis and the RR of MTCT for women infected with both syphilis and HIV. Subgroup analyses were undertaken by study location, sample size, use of anti-retroviral therapy and study quality. Results: Sixteen studies with a combined sample of 110 573 pregnant women were included in the analysis. Of these, ten reported HIV seroprevalences among pregnant women with syphilis and six studies evaluated the influence of syphilis infection on MTCT of HIV. Pooled estimates yielded a HIV seroprevalence of 11.6% (95 % CI : 6.7%-19.5%) among pregnant women with syphilis. We estimated that the risk of MTCT of HIV was 1.86 times ( RR= 1.86, 95 % CI : 0.89%-3.89%) higher among pregnant women with syphilis compared with those only infected with HIV-although this effect was not statistically significant. Cochran's Q test showed a high degree of heterogeneity in estimates of HIV seroprevalence and the effect of syphilis infection on MTCT of HIV across studies ( I 2 =89.4% and 86.2%, respectively, PHIV seroprevalences of 24.9% (95 %CI : 17.4%-34.3%) in Africa, 2.8% (95 % CI : 1.4%-5.6%) in

    Mannose binding lectin (MBL) is a pathogen pattern recognition protein involved in antimicrobial activities. Variation in MBL2 gene has been extensively implicated in differential outcomes of infectious diseases in studies conducted outside Africa, but virtually very little is known on the role of this candidate gene in the African continent. We investigated human genetic variations in MBL2 in a Zimbabwean pediatric population and their putative associations with HIV infection in perinatally exposed children. One hundred and four children aged 7 to 9 years comprising 68 perinatally exposed to HIV (32 who were born infected and 36 who were uninfected) and 36 unexposed controls were recruited. DNA samples were genotyped for MBL2 polymorphisms using PCR-RFLP and sequencing. HIV infected children had markedly variable and significantly lower mean height (p=0.03) and weight (p=0.005) when compared to the uninfected children. Using all samples, frequencies for MBL2 genetic variants for the Zimbabwean population were calculated. Twelve single nucleotide polymorphisms were observed and minor alleles occurred with the following frequencies: -550C>G (G: 0.02), -435G>A (A: 0.08), -428A>C (C: 0.39), -394A>G (A: 0.39), -328AGAGAA ins/del (AGAGAA ins: 0.44), -245G>A (A: 0.05), -221C>G (C: 0.12), -111A>T (T: 0.10), -70C>T (C: 0.46), +4C>T (C: 0.45), novel -595G>A (A: 0.02), and 170G>A (0.24). We found that the MBL2 +4T variant displayed a trend for association with reduced risk of HIV transmission from mother-to-child but the remaining vast majority of the genetic markers did not show a significant association. We conclude (1) the MBL2 gene is highly polymorphic in the Zimbabwean population, and (2) MBL2 genetic variation does not appear to play a major role in influencing the risk of mother-to-child HIV transmission in our study sample. These observations contest the hitherto significant role of this candidate gene for HIV transmission from mother-to-child in non

    Full Text Available Background: The reported coverage of any antiretroviral (ARV prophylaxis for prevention of mother-to-child transmission (PMTCT has increased in sub-Saharan Africa in recent years, but was still only 60% in 2010. However, the coverage estimate is subject to overestimations since it only considers enrolment and not completion of the PMTCT programme. The PMTCT programme is complex as it builds on a cascade of sequential interventions that should take place to reduce mother-to-child transmission (MTCT of HIV: starting with antenatal care (ANC, HIV testing, and ARVs for the woman and the baby. Objective: The objective was to estimate the number of children infected with HIV in a district population, using empirical data on uptake of PMTCT components combined with data on MTCT rates. Design: This study is based on a population-based cohort of pregnant women recruited in the Iganga-Mayuge Health and Demographic Surveillance Site in rural Uganda 2008–2010. We later modelled different scenarios assuming increased uptake of specific PMTCT components to estimate the impact on MTCT for each scenario. Results: In this setting, HIV infections in children could be reduced by 28% by increasing HIV testing capacity at health facilities to ensure 100% testing among women seeking ANC. Providing ART to all women who received ARV prophylaxis would give an 18% MTCT reduction. Conclusions: Our results highlight the urgency in scaling-up universal access to HIV testing at all ANC facilities, and the potential gains of early enrolment of all pregnant women on antiretroviral treatment for PMTCT. Further, to determine the effectiveness of PMTCT programmes in different settings, it is crucial to analyse at what stages of the PMTCT cascade that dropouts occur to target interventions accordingly.

    Management of pregnant women with human immunodeficiency virus (HIV) type 2 infection remains unclear because of its low prevalence and important differences from HIV-1. Pregnant women monoinfected with HIV-2 or HIV-1 and their infants enrolled in the prospective, national, multicenter French Perinatal Cohort between 1986 and 2007. Overall, 2.6% (223/8660) of mothers were infected with HIV-2, and they accounted for 3.1% (367/ 11841) of the total births. Most were born in sub-Saharan Africa. A higher proportion of HIV-2-infected mothers than HIV-1-infected mothers had no symptoms, had received no antiretroviral therapy at conception (85.9% vs 66.7%), and had received no antiretroviral therapy during pregnancy (42.8% vs 19.9%), particularly highly active antiretroviral therapy (HAART) (79.7% vs 46.1%), and they had higher CD4 cell counts near delivery (median, 574 vs 452 cells/mm3; P < .01). If antiretroviral therapy was used, it was started at a later gestational age for HIV- 2-infected mothers (median, 28 vs 25 weeks; P < .01). HIV-2-infected mothers were more likely to deliver vaginally (67.9% vs 49.3%) and to breastfeed (3.6% vs 0.6%; P < .01), and their infants less frequently received postexposure prophylaxis. In the period 2000-2007, the proportion with viral load <100 copies/mL at delivery was 90.5% of HIV-2-infected mothers, compared with 76.2% of HIV-1-infected mothers (P=.1). There were 2 cases of transmission: 1 case in 1993 occurred following maternal primary infection, and the other case occurred postnatally in 2002 and involved a mother with severe immune deficiency. The mother-to-child transmission rate for HIV-2 was 0.6% (95% confidence interval, 0.07%-2.2%). Care for HIV-2-infected pregnant women rests on expert opinion. The mother-to-child transmission residual rate (0.07%-2.2%) argues for systematic treatment: protease inhibitor-based HAART for women requiring antiretrov

    Background Intrapartum single-dose nevirapine decreases mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) but promotes nevirapine resistance. Although resistant viruses fade to undetectable levels in plasma, they may persist as stably integrated proviruses within the latent reservoir in resting CD4+ T cells, potentially complicating future treatment. Methods Blood samples were collected from 60 women from South Africa and Uganda >6 months after they had received single-dose nevirapine. To selectively analyze the stable latent form of HIV-1, resting CD4+ T cells were isolated and activated in the presence of reverse-transcriptase inhibitors and integrase inhibitors, which allows for the specific isolation of viruses produced by cells with stably integrated proviral DNA. These viruses were then analyzed for nevirapine resistance. Results Although only a small number of latently infected cells were present in each blood sample (mean, 162 cells), nevirapine resistance mutations (K103N and G190A) were detected in the latent reservoir of 4 (8%) of 50 evaluable women. Conclusions A single dose of nevirapine can establish antiretroviral resistance within the latent reservoir. This results in a potentially lifelong risk of reemergence of nevirapine-resistant virus and highlights the need for strategies to prevent transmission that do not compromise successful future treatment.

    Despite a more proactive approach to reducing new HIV infections in infants through lifelong treatment (Option B+ policy) for infected pregnant women, prevention of mother-to-child transmission of HIV (PMTCT) has not been fully effective in Papua, Indonesia. Mother-to-child transmission (MTCT) is the second greatest risk factor for HIV infection in the community, and an elimination target of Option B+ for PMTCT in Papua through investigation of facilitators and barriers to women's uptake and adherence to antiretroviral therapy (ART) in the program. This information is vital for improving program outcomes and success of program scale up in similar settings in Papua. In-depth interviews were conducted with 20 women and 20 PMTCT health workers at two main referral hospitals for PMTCT in Papua. Development of interview guides was informed by the socio-ecological framework. Qualitative data were managed with NVivo11 software and themes were analysed using template analysis. Factors influencing women's uptake and adherence in Option B+ for PMTCT were identified through final analysis of key themes. Factors that motivated PMTCT uptake and adherence were good quality post-test HIV counselling, belief in the efficacy of antiretroviral (ARV) attained through personal or peer experiences, and a partner who did not prevent women from seeking PMTCT care. Key barriers for PMTCT participation included doubts about ARV efficacy, particularly for asymptomatic women, unsupportive partners who actively prevented women from seeking treatment, and women's concerns about community stigma and discrimination. Results suggest that PMTCT program success is determined by facilitators and barriers from across the spectrum of the socio-ecological model. While roll out of Option B+ as current national policy for pregnant women in Papua has improved detection and enrolment of HIV-positive women, health facilities need to address various existing and potential issues to ensure long-term adherence

    Emerging international guidelines for the prevention of mother-to-child transmission of HIV infection across sub-Saharan Africa call for the initiation of a triple-drug antiretroviral regimen containing tenofovir, a potentially nephrotoxic agent, in all HIV-infected pregnant women at the first antenatal clinic visit. While there are significant benefits to the rapid initiation of antiretroviral therapy (ART) in pregnancy, there are few data on the prevalence of pre-existing renal disease in HIV-infected pregnant women and in turn, the potential risks of this approach are not well understood. We analysed data on renal function in consecutive patients eligible for ART at a large primary healthcare clinic in Cape Town. All individuals were screened for renal dysfunction via serum creatinine and estimation of creatinine clearance via the Cockroft-Gault equation. Over a 2-year period, 238 pregnant women, 1014 non-pregnant women and 609 men were screened to initiate ART. Pregnant women eligible were significantly younger, in earlier stages of HIV disease, had higher CD4 cell counts and lower HIV viral loads, than non-pregnant adults. The median serum creatinine in pregnant women (46 µmol/L) was significantly lower and the median creatinine clearance (163 ml/min/1.73 m(2) ) was significantly higher than other groups (P pregnant women had moderate renal dysfunction before ART initiation, with no instances of severe dysfunction observed, compared to 7% moderate or severe renal dysfunction in non-pregnant women or men (P HIV-infected pregnant women is significantly less common than in other HIV-infected adults eligible for ART. The risks associated with initiating tenofovir immediately in pregnant women before reviewing serum creatinine results may be limited, and the benefits of rapid ART initiation in pregnancy may outweigh possible risks of nephrotoxicity. © 2013 John Wiley & Sons Ltd.

    We estimated HIV-free infant survival and mother-to-child HIV transmission (MTCT) rates in Zimbabwe, some of the first community-based estimates from a UNAIDS priority country. In 2012 we surveyed mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. Enrolled infants were born 9-18 months before the survey. We collected questionnaires, blood samples for HIV testing, and verbal autopsies for deceased mothers/infants. Estimates were assessed among i) all HIV-exposed infants, as part of an impact evaluation of Option A of the 2010 WHO guidelines (rolled out in Zimbabwe in 2011), and ii) the subgroup of infants unexposed to Option A. We compared province-level MTCT rates measured among women in the community with MTCT rates measured using program monitoring data from facilities serving those communities. Among 8568 women with known HIV serostatus, 1107 (12.9%) were HIV-infected. Among all HIV-exposed infants, HIV-free infant survival was 90.9% (95% confidence interval (CI): 88.7-92.7) and MTCT was 8.8% (95% CI: 6.9-11.1). Sixty-six percent of HIV-exposed infants were still breastfeeding. Among the 762 infants born before Option A was implemented, 90.5% (95% CI: 88.1-92.5) were alive and HIV-uninfected at 9-18 months of age, and 9.1% (95%CI: 7.1-11.7) were HIV-infected. In four provinces, the community-based MTCT rate was higher than the facility-based MTCT rate. In Harare, the community and facility-based rates were 6.0% and 9.1%, respectively. By 2012 Zimbabwe had made substantial progress towards the elimination of MTCT. Our HIV-free infant survival and MTCT estimates capture HIV transmissions during pregnancy, delivery and breastfeeding regardless of whether or not mothers accessed health services. These estimates also provide a baseline against which to measure the impact of Option A guidelines (and subsequently Option B+).

    Full Text Available Women may have persistent risk of HIV acquisition during pregnancy and postpartum. Estimating risk of HIV during these periods is important to inform optimal prevention approaches. We performed a systematic review and meta-analysis to estimate maternal HIV incidence during pregnancy/postpartum and to compare mother-to-child HIV transmission (MTCT risk among women with incident versus chronic infection.We searched PubMed, Embase, and AIDS-related conference abstracts between January 1, 1980, and October 31, 2013, for articles and abstracts describing HIV acquisition during pregnancy/postpartum. The inclusion criterion was studies with data on recent HIV during pregnancy/postpartum. Random effects models were constructed to pool HIV incidence rates, cumulative HIV incidence, hazard ratios (HRs, or odds ratios (ORs summarizing the association between pregnancy/postpartum status and HIV incidence, and MTCT risk and rates.

    To investigate the willingness of Traditional Birth Attendants (TBAs) to provide single dose antiretroviral prophylaxis to infants born to mothers with HIV and the feasibility of providing the TBAs with antiretroviral medication. 2 focus groups with a total of 17 registered TBAs. Lilongwe, Malawi. TBAs were recruited by local health workers and participated in focus groups assessing their attitudes towards participation in a PMTCT program. TBAs were willing to participate in this prevention of mother-to-child HIV transmission (PMTCT) program and helped identify barriers to their participation. Given appropriate support and training, TBAs' participation in PMTCT programs could be an additional way to deliver medication to mothers and neonates who might otherwise miss crucial doses of medication.

    Using spatial-temporal analyses to understand coverage and trends in elimination of mother-to-child transmission of HIV (e-MTCT) efforts may be helpful in ensuring timely services are delivered to the right place. We present spatial-temporal analysis of seven years of HIV early infant diagnosis (EID) data collected from 12 districts in western Kenya from January 2007 to November 2013, during pre-Option B+ use. We included in the analysis infants up to one year old. We performed trend analysis using extended Cochran-Mantel-Haenszel stratified test and logistic regression models to examine trends and associations of infant HIV status at first diagnosis with: early diagnosis (ever having breastfed, use of single dose nevirapine, and maternal antiretroviral therapy status. We examined these covariates and fitted spatial and spatial-temporal semiparametric Poisson regression models to explain HIV-infection rates using R-integrated nested Laplace approximation package. We calculated new infections per 100,000 live births and used Quantum GIS to map fitted MTCT estimates for each district in Nyanza region. Median age was two months, interquartile range 1.5-5.8 months. Unadjusted pooled positive rate was 11.8% in the seven-years period and declined from 19.7% in 2007 to 7.0% in 2013, p best in explaining geographical variation in MTCT. Improved EID uptake and reduced MTCT rates are indicators of progress towards e-MTCT. Cojoined analysis of time and covariates in a spatial context provides a robust approach for explaining differences in programmatic impact over time. During this pre-Option B+ period, the prevention of mother to child transmission program in this region has not achieved e-MTCT target of ≤50 infections per 100,000 live births. Geographical disparities in program achievements may signify gaps in spatial distribution of e-MTCT efforts and could indicate areas needing further resources and interventions.

    In Brazil, due to the rapid increase in programmes for the prevention of mother-to-child transmission (PMTCT), routine programme data are widely available. The objective of this study was to assess the utility of programmatic data to replace HIV surveillance based on the antenatal care (ANC) surveillance survey (SS). We analysed ANC SS data from 219 maternity service clinics. PMTCT variables were extracted from the ANC SS data collection form, which allowed us to capture and compare the ANC SS data and PMTCT HIV test results for each pregnant woman who completed the ANC SS. Both the PMTCT programme and the ANC SS tested for HIV using sequential ELISA and western blot for confirmation. We assessed the completeness (% missing) of the PMTC data included in the ANC SS. Of the 36,713 pregnant women who had ANC SS HIV tests performed, 30,588 also underwent PMTCT HIV testing. The HIV prevalence rate from routine PMTCT testing was 0.36%, compared to 0.38% from the ANC SS testing (relative difference -0.05%; absolute difference -0.02%). The relative difference in prevalence rates between pregnant women in northern Brazil and pregnant women central-west Brazil was -0.98 and 0.66, respectively. Of the 29,856 women who had HIV test results from both the PMTCT and ANC SS, the positive percent agreement of the PMTCT versus the surveillance test was 84.1% (95% confidence interval [CI]: 74.8-91.0), and the negative percent agreement was 99.9% (95% CI: 99.9-100.0). The PMTCT HIV testing uptake was 86.4%. The ANC SS HIV prevalence was 0.33% among PMTCT non-refusers and 0.59% among refusers, with a percent bias of -10.80% and a differential prevalence ratio of 0.56. Syphilis and HIV testing results were complete in 98% and 97.6% of PMTCT reports, respectively. The reported HIV status for the women at clinic entry was missing. Although there were consistent HIV prevalence estimates from the PMTCT data and the ANC SS, the overall positive percent agreement of 84.1% falls below the

    It has been hypothesized that neutralizing antibodies (NAbs) should have broad specificity to be effective in protection against diverse HIV-1 variants. The mother-to-child transmission model of HIV-1 provides the opportunity to examine whether the breadth of maternal NAbs is associated with protection of infants from infection. Samples were obtained at delivery from 57 transmitting mothers (T) matched with 57 nontransmitting mothers (NT) enrolled in the multicenter French perinatal cohort (ANRS EPF CO1) between 1990 and 1996. Sixty-eight (59.6%) and 46 (40.4%) women were infected by B and non-B viruses, respectively. Neutralization assays were carried out with TZM-bl cells, using a panel of 10 primary isolates of 6 clades (A, B, C, F, CRF01_AE, and CRF02_AG), selected for their moderate or low sensitivity to neutralization. Neutralization breadths were not statistically different between T and NT mothers. However, a few statistically significant differences were observed, with higher frequencies or titers of NAbs toward several individual strains for NT mothers when the clade B-infected or non-clade B-infected mothers were analyzed separately. Our study confirms that the breadth of maternal NAbs is not associated with protection of infants from infection.

This study describes findings from an Early Infant Diagnosis (EID program and the effectiveness of a prevention of mother-to-child transmission (PMTCT intervention in six health facilities in Cross-River and Akwa-Ibom states, south-south Nigeria. Methods This was a retrospective study. Records of 702 perinatally exposed babies aged six weeks to 18 months who had a DNA PCR test between November 2007 and July 2009 were reviewed. Details of the ARV regimen received to prevent mother-to-child transmission (MTCT, breastfeeding choices, HIV test results, turn around time (TAT for results and post test ART enrolment status of the babies were analysed.

Methods We analyzed serosurvey data collected in 2012 and 2014 among mother-infant pairs from catchment areas (CAs) of 132 health facilities from 5 of 10 provinces in Zimbabwe. Eligible infants (alive or deceased) were born 9–18 months before each survey to mothers ≥16 years old. We randomly selected mother-infant pairs and conducted questionnaires, verbal autopsies and collected blood samples. We estimated: 1) the HIV-free infant survival and MTCT rate within each CA and compared the 2012 and 2014 estimates using a paired t-test, 2) number of HIV infections averted due to the intervention. Results We analyzed 7,249 mother-infant pairs with viable maternal specimens collected in 2012 and 8,551 in 2014. The mean difference in the CA-level MTCT between 2014 and 2012 was −5.2 percentage points (95% confidence interval (CI)=−8.1, −2.3, pOption A regimen. The association between HIV-free infant survival and duration of Option A implementation was not significant at the multivariate level (p=0.093).

    Traditional birth attendants (TBAs) assist most deliveries in Nigeria. Knowing and understanding all issues surrounding HIV/AIDS and Prevention of Mother-To-Child Transmission of HIV (PMTCT) can help them to protect themselves and others. This study aimed to assess the knowledge and practice of PMTCT amongst TBAs in Lagos, Nigeria. This was a cross-sectional survey. Multistage sampling method was used to select 108 registered TBAs in 2 local governments areas who were interviewed using a pre-tested questionnaire. All the respondents were aware of HIV but their awareness of PMTCT specifically was not as high. Only 8.3% of the respondents had good level of knowledge about HIV and PMTCT and up to 13% of them claimed to be able to cure HIV using native remedies. The practices of HIV counseling of patients and referral of patients for HIV testing were low and higher levels of knowledge positively influenced these practices significantly (p < 0.05). They were also deficient in certain measures to prevent infection of patients and themselves. Most of the TBAs did not have adequate knowledge and practice of PMTCT illustrating the need for periodic PMTCT training for TBAs.

    The 2007 United Nations General Assembly Report on HIV/AIDS in Zimbabwe reported nondisclosure of HIV status as a challenge in the PMTCT programme. Preliminary investigations on nondisclosure among 21 women tested for HIV at Chinhoyi Hospital showed that only six had disclosed their HIV status. We investigated the determinants of nondisclosure of HIV status. A cross sectional analytic study was conducted at six health facilities in Makonde district. The Theory of Planned Behaviour was adapted to guide socio-cultural variables assessed. Antenatal and postnatal women tested for HIV in the PMTCT program who consented to participate were interviewed. We enrolled 334 women. Thirty four percent (114) did not disclose their HIV status. Among HIV positive respondents, 43% (25) did not disclose their status. Women who believed disclosure caused physical abuse (OR=1.81, 95% CI: 1.17-2.90), caused divorce (OR=2.01, 95% CI: 1.25-3.22) and was unimportant (OR= 2.26, 95% CI: 1.33-3.87) were two times less likely to disclose their status. Respondents who received group HIV pre-test counselling were 2.4 times more likely not to disclose. Receiving ANC HIV education at least twice and referral for psychosocial support were significantly protective [OR 0.54 (95% CI 0.24-0.63) and 0.16 (95% CI: 0.06-0.41) respectively. Independent determinants of nondisclosure among HIV positive women were perception that disclosure would cause divorce (AOR=7.82, p=0.03), living with an extended family (AOR=10.3, p=0.01) and needing spousal approval of HIV testing (AOR=0.11, pcauses divorce, abuse or is unimportant contributes to nondisclosure. Identifying women with social challenges and strengthening their referral for psychosocial support can improve disclosure of HIV status and reduce mother to child transmission of HIV.

    Full Text Available Abstract Background Single-dose nevirapine (SDNVP for the prevention of mother-to-child HIV transmission (PMTCT results in the selection of resistance mutants among HIV-infected mothers. The effects of these mutations on the efficacy of SDNVP use in a subsequent pregnancy are not well understood. Methods We compared risks of perinatal HIV transmission between multiparous women who had previously received a dose of SDNVP (exposed and those that had not (unexposed and who were given SDNVP for the index pregnancy within a PMTCT clinical study. We also compared transmission risks among exposed and unexposed women who had two consecutive pregnancies within the trial. Logistic regression modeling was used to adjust for possible confounders. Results Transmission risks did not differ between 59 SDNVP-exposed and 782 unexposed women in unadjusted analysis or after adjustment for viral load and disease stage (adjusted odds ratio 0.6, 95% confidence interval [CI] 0.2 to 2.0. Among 43 women who had two consecutive pregnancies during the study, transmission risks were 7% (95% CI 1% to 19% at both the first (unexposed and second (exposed delivery. The results were unchanged, if infant death was included as an outcome. Conclusion These data suggest that the efficacy of SDNVP may not be diminished when reused in subsequent pregnancies.

Clinical trials have demonstrated the efficacy of antiretroviral regimens to interrupt HIV transmission through the antenatal, intrapartum, and postnatal periods. Scientific discoveries have been rapidly translated into health policy, bolstered by substantial investment in health infrastructure capable of delivering increasingly complex services. A new scientific agenda is also emerging, one that is focused on the challenges of effective and sustainable program implementation. Finally, global campaigns to "virtually eliminate" pediatric HIV and dramatically reduce HIV-related maternal mortality have mobilized new resources and renewed political will. Each of these developments marks a major step in regional PMTCT efforts; their convergence signals a time of rapid progress in the field, characterized by an increased interdependency between clinical research, program implementation, and policy. In this review, we take stock of recent advances across each of these areas, highlighting the challenges--and opportunities--of improving health services for HIV-infected mothers and their children across the region.

This study reports on the barriers preventing mothers of vertically infected HIV-seropositive infants to use the PMTCT services at the Federal Medical Centre, Makurdi, Nigeria.Methods: This is a descriptive study conducted between January and April, 2014. A quantitative survey was applied to detect barriers along the PMTCT services cascade among 52 mothers of vertically infected HIV-seropositive infants. This includes 22 women who attended antenatal care at the Federal Medical Centre (designated as Group A mothers and 30 women who did not receive any form of PMTCT service (Group B mothers. The study was supplemented with a focused group discussion involving 12 discussants from the two groups.Results: In the quantitative assessment: among the Group A mothers, falling asleep was the most common reason (n=22, 100% for missing therapeutic/prophylactic antiretroviral medicine; financial constraint (n=22, 100% was the most common reason for antenatal care visit defaults; and a lot of the mothers (n=11, 50.0% did not give nevirapine to their newborns because they delivered at home. Among Group B mothers, unawareness of HIV-seropositive status was the most common reason (n=28, 93.3% given for not accessing PMTCT services. In the qualitative study: noninvolvement of male partners, stigma and discrimination experienced by HIV-seropositive mothers, financial constraints in couples, involvement of traditional birth attendants in antenatal care and delivery of HIV-infected women, unawareness of HIV-seropositive status by pregnant women, poor health system, and the lack of funding for PMTCT

    To determine the percentage of infected children for whom nevirapine (NVP) was used to prevent peripartum mother-to-child transmission (MTCT) of HIV in Yaoundé, Cameroon. The study was a prospective Public Health Pilot Program covering a 3-year period (January 2000-December 2002). Counseled and consenting HIV-1-positive pregnant women were given a single dose of NVP at the onset of labor. Babies were given 2 mg/kg NVP syrup within the first 72 hours of life. NVP-treated children were regularly followed up and examined for HIV-1 infection at 6-8 weeks and 5-6 months through plasma viral load (VL) quantification with the bDNA system. One hundred twenty-three children were diagnosed with perinatal HIV-1 infection at 6-8 weeks and 5-6 months. Thirteen children (10.6% [13/123]; 95% confidence interval, 5.1-16) were infected and presented with high VLs, in general >500,000 copies/mL. Two children had intermediate VLs (between 50 and 3500 copies/mL) at both time points. One hundred seven children (87%) were considered not infected at 6-8 weeks of age. Our results indicate that the HIV-1 MTCT rate 6-8 weeks after NVP administration was not >13% (16/123), thus demonstrating the effectiveness of NVP for lowering the risk of HIV-1 MTCT in real-life settings.

    The objective of this study was to identify determinants of human immunodeficiency virus (HIV) knowledge regarding mother-to-child transmission (MTCT) among pregnant women at Tijuana General Hospital, Baja California, Mexico. Between March and November 2003, patients from the prenatal care (n = 1294) and labor and delivery (L&D) units (n = 495) participated in a cross-sectional study to measure HIV knowledge. Less than one-third (30%) knew that HIV could be transmitted to a child during delivery, and 36% knew that HIV could be transmitted by breast-feeding. Only 27% knew that an MTCT could be prevented. Prenatal patients were more likely to know that MTCT was preventable (prenatal: 31% versus L&D 25%; P = .02). Logistic regression indicated that prenatal patients (odds ratio = 1.49, confidence interval 1.07-2.07) were more likely to know that HIV could be transmitted through breast-feeding. Overall, both groups had poor knowledge regarding MTCT of HIV. © The Author(s) 2014.

    Since 2012, lifelong antiretroviral therapy for all HIV-positive pregnant women ("Option B+") is recommended by WHO for the prevention of mother-to-child transmission of HIV (PMTCT). Many sub-Saharan African countries have since introduced this regimen, but to date, longer-term outcome evaluations are scarce. We conducted an observational study in Fort Portal Municipality, Uganda, to describe uptake and adherence of Option B+ during pregnancy. HIV-positive women approaching antenatal care (ANC) services in two hospitals were enrolled and followed-up at monthly routine ANC visits until delivery. At each visit, next to sociodemographic and clinical data, we assessed drug adherence through pill counts. In total, 124 HIV-positive pregnant women were enrolled in our study; from these, 80.8% had not been aware of their positive serostatus before. Forty-five PMTCT clients (36.3%) never returned to ANC after their first visit. Protective factors (p HIV status knowledge, status disclosure before or at first ANC visit, and tertiary education. Among those clients starting Option B+, the median adherence during pregnancy was 95.7% pill intake. Rather low adherence (pregnancy. Healthcare providers should place high emphasis on individual PMTCT counseling at first ANC encounter, and pay special attention to those women previously unaware of their HIV status. However, after initial uptake, high adherence seems to be feasible for Option B+.

We used cases of pregnant women infected with HIV identified in the "Birth in Brazil" study, and cases of AIDS in children under 5 years old identified in the NIS, to estimate the MTCT of HIV infection in the country, with a 95% confidence interval. We also estimated the HIV cascade (HIV diagnosis; use of antiretroviral treatment (ART) during pregnancy, labour, and for the newborn; adequate care during childbirth considering viral load at birth; and no breastfeeding) using data from the same sources. MTCT of HIV of 2.0% (95% CI 0.3%-13.8%). At birth, 84.0% of HIV infected woman showed a positive HIV diagnosis, 74.9% received combined ART during pregnancy, 80.7% received ART during childbirth, 77.1% received adequate care during childbirth, 86.8% of newborns received ART within the first 24 hours after birth, and 2.8% of newborns were breastfed. Considering all steps, 61.3% of the women (95% CI 48.3%-72.8%) received all available medical interventions. In the analysis restricted to women identified in the NIS, 65.3% (95% CI 48.0%-79.3%) of HIV infected women received all available medical interventions. Brazil has healthcare policies that guarantee free access to tests, ART and substitutes for maternal milk. However, missed opportunities to prevent MTCT of HIV were identified in at least one-third of women and may be making it difficult to reach HIV-elimination targets especially in the less developed country regions.

    Full Text Available BACKGROUND: The objective of this review was to assess the uptake of WHO recommended integrated perinatal prevention of mother-to-child transmission (PMTCT of HIV interventions in low- and middle-income countries. METHODS AND FINDINGS: We searched 21 databases for observational studies presenting uptake of integrated PMTCT programs in low- and middle-income countries. Forty-one studies on programs implemented between 1997 and 2006, met inclusion criteria. The proportion of women attending antenatal care who were counseled and who were tested was high; 96% (range 30-100% and 81% (range 26-100%, respectively. However, the overall median proportion of HIV positive women provided with antiretroviral prophylaxis in antenatal care and attending labor ward was 55% (range 22-99% and 60% (range 19-100%, respectively. The proportion of women with unknown HIV status, tested for HIV at labor ward was 70%. Overall, 79% (range 44-100% of infants were tested for HIV and 11% (range 3-18% of them were HIV positive. We designed two PMTCT cascades using studies with outcomes for all perinatal PMTCT interventions which showed that an estimated 22% of all HIV positive women attending antenatal care and 11% of all HIV positive women delivering at labor ward were not notified about their HIV status and did not participate in PMTCT program. Only 17% of HIV positive antenatal care attendees and their infants are known to have taken antiretroviral prophylaxis. CONCLUSION: The existing evidence provides information only about the initial PMTCT programs which were based on the old WHO PMTCT guidelines. The uptake of counseling and HIV testing among pregnant women attending antenatal care was high, but their retention in PMTCT programs was low. The majority of women in the included studies did not receive ARV prophylaxis in antenatal care; nor did they attend labor ward. More studies evaluating the uptake in current PMTCT programs are urgently needed.

    Full Text Available Economic analyses of patients’ costs are pertinent to improve effective healthcare services including the prevention of mother-to-child HIV/AIDS transmission (PMTCT. This study assessed the direct and non-direct medical costs borne by pregnant women attending PMTCT services in urban (high-HIV prevalence and rural (low-HIV prevalence settings, in Ethiopia. Patient-level direct medical costs and direct non-medical data were collected from HIV-positive pregnant women in six regions. The cost estimation was classified as direct medical (service fee, drugs and laboratory and direct non-medical (food, transportation and accommodation. The mean direct medical expense per patient per year was Ethiopian birr (ETB 746 (US$ 38 in the urban settings, as compared to ETB 368 (US$ 19 in the rural settings. On average, a pregnant woman from urban and rural catchments incurred direct non-medical costs of ETB 6,435 (US$ 327 and ETB 2,154 (US$ 110 per year, respectively. On average, non-medical costs of friend/relative/guardian were ETB 2,595 (US$ 132 and ETB 2,919 (US$ 148.39 in the urban and rural settings, respectively. Although the PMTCT service is provided free of charge, HIV-positive pregnant women and infant pairs still face a substantial amount of out-of-pocket spending due to direct medical and non-medical costs.

    In this article, we examine barriers to HIV testing uptake and participation in prevention of mother-to-child HIV transmission (PMTCT) services among adolescent mothers aged 15 to 19 years in rural and urban Limpopo Province, South Africa. We used the narrative research method involving key informants constructing typical case studies of adolescent experiences with HIV testing and entry into PMTCT. Case studies formed the basis of a community-based questionnaire and focus group discussions with adolescent mothers. Client-counselor dynamics during pretest counseling were pivotal in determining uptake and participation, and counselor profile strongly influenced the nature of the interaction. Other factors found to influence adherence to PMTCT recommendations included HIV and early premarital pregnancy stigma, fear of a positive test result, and concerns over confidentiality and poor treatment by health care providers. Adolescents described elaborate strategies to avoid HIV disclosure to labor and delivery staff, despite knowing this would mean no antiretroviral therapy for their newborn infants. Theoretical, methodological, and programmatic implications of study findings are also discussed.

    Full Text Available Male partner involvement (MPI can contribute to the success of programs aimed at preventing mother-to-child transmission (PMTCT of HIV. However, the definition and measures of MPI differ according to context. This study utilized secondary cross-sectional data to investigate the prevalence and determinants of MPI among 463 male partners of HIV-infected pregnant women in rural South Africa. Results indicated that 44.1% of male partners reported involvement in most or all specified male partner involvement activities (i.e., scores of 7 to 9. Descriptive, correlation and multiple linear-regression analyses were conducted. Positive predictors of MPI included relationship status, own HIV status, awareness of female partner’s positive HIV status, female partner’s desire to have more children, having family planning discussions with provider, condom use to prevent HIV and sexually transmitted infections (STIs, and partner reasoning skills. Negative predictors included partner verbal aggression. Overall, although MPI is low, the study underlines important information that could be used to develop interventions aimed at improving maternal and infant health in PMTCT programs in South Africa.

    Traditional birth attendants (TBAs) play an important role in the provision of care to pregnant women in rural parts of Nigeria, but they are barely engaged by the formal healthcare system in expanding the low coverage of prevention of mother-to-child transmission of HIV (PMTCT) services. Using a systematic approach, we engaged TBAs in Abia and Taraba States to scale-up PMTCT services under the National Agency for Control of AIDS Comprehensive AIDS Program with States. We conducted mapping of the TBAs, built their capacities, obtained their buy-in on mobilization of their clients and other pregnant women for HIV testing service outreaches, and established referral and linkage systems. A total of 720 TBAs were mapped (Abia 407; Taraba 313). Three hundred and ninety-nine TBAs who participated in the capacity-building meeting were linked to 115 primary healthcare centers (PHCs) in Abia State, while 245 TBAs were linked to 27 PHCs in Taraba State. From July 2016 to March 2017, the outreaches contributed 20% to the overall total number of pregnant women counseled, tested and received results, and 12% to the total number of HIV-infected women identified. There was a considerable yield of HIV-infected pregnant women among those tested in the TBA outreaches in comparison with the supported antenatal facilities (2% versus 3%, respectively). Engaging TBAs has the potential to improve the coverage of PMTCT services in Nigeria.

    The objective of our intervention was to examine the benefits of incorporating traditional birth attendants (TBA) in HIV Prevention of Mother to Child Transmission (PMTCT) service delivery. We developed a training curriculum for TBAs related to PMTCT and current TBA roles in Malawi. Fourteen TBAs and seven TBA assistants serving 4 urban health centre catchment areas were assessed, trained and supervised. Focus group discussions with the TBAs were conducted after implementation of the program. From March 2008 to August 2009, a total of 4017 pregnant women visited TBAs, out of which 2133 (53.1%) were directly referred to health facilities and 1,884 (46.9%) women delivered at TBAs and subsequently referred. 168 HIV positive women were identified by TBAs. Of these, 86/168 (51.2%) women received nevirapine and 46/168 (27.4%) HIV exposed infants received nevirapine. The challenges in providing PMTCT services included lack of transportation for referrals and absence of a reporting system to confirm the woman's arrival at the health center. Non-disclosure of HIV status by patients to the TBAs resulted in inability to assist nevirapine uptake. TBAs, when trained and well-supervised, can supplement efforts to provide PMTCT services in communities.

    Mother-to-child transmission of HIV (MTCT) is the major form of acquiring the disease among children. The loss to follow-up (LTF) of mothers and their children is a problem that affects the effectiveness of programs for the prevention of mother-to-child transmission (PMTCT). The aim of this study is to identify risk factors associated with the LTF of HIV-exposed children in the state of Pernambuco, Brazil. A retrospective cohort study was carried out with 1200 HIV-exposed children born between 2000 and 2009, registered up to the age of 2 months in a public health PMTCT program. Children were considered LTF if they did not return for scheduled visits to monitor infection status. Univariate and multivariate logistic regression analyses were conducted to identify risk factors for LTF. A total of 185 children (15.4%; CI: 95%: 13.4-17.4%) met the case definition of LTF before the determination of serological HIV status. Risk factors independently associated with LTF were mother-child pairs who reside in rural and remote areas (OR 1.86; 95% CI: 1.30-2.66) and mothers who use illicit drugs (OR 1.8; 95% CI: 1.08-3.0). Initiation of the PMTCT during pregnancy was a protective factor for LTF (OR 0.69; 95% CI: 0.49-0.96). The decentralization of support services for HIV-exposed children to other cities in the state seems to be crucial for the accurate monitoring of outcomes. It is also important to introduce additional measures addressing mothers who are drug users so that they remain in the program: an intensive follow-up program that actively searches for absentee mother-child pairs, support from social services and treatment for drug-dependency. The findings of this study highlight the importance of diagnosing mothers as early as possible in order to conduct a more complete follow-up period of the children. Solving the above-mentioned problems is a challenge, which must be overcome so as to improve the quality of PMTCT.

As more women contract the virus, the number of children infected in utero, intra-partum, and during breastfeeding has been growing. This study assessed the knowledge and attitude of women of child bearing age towards the prevention of mother-to-child-transmission (PMTCT of HIV. Materials and methods: This is a descriptive cross sectional survey of 420 women of the reproductive age group (15–49 years selected using a multistage sampling technique. Data were obtained using interviewer-administered, pretested, semistructured questionnaires. The data were analyzed using the Statistical Package for Social Sciences (SPSS software version 15. Results: A high level of awareness about HIV/acquired immunodeficiency syndrome (AIDS was observed among the respondents (99.8%. The knowledge about MTCT and PMTCT of HIV was high, 92.1% and 91.4%, respectively. However, a significant portion (71.27% of the study population had poor attitudes towards PMTCT of HIV. Conclusion: Despite the high level of awareness of HIV/AIDS, and good knowledge about MTCT and PMTCT of HIV/AIDS among the respondents, the attitude towards PMTCT is poor. There is need for the involvement of the stakeholders in bridging the gap between knowledge and attitude of prevention of MTCT of HIV among women.

    Within the first year of implementation, 43% of women who tested HIV positive at their first antenatal care visit were no longer retained and being followed in the free prevention of mother to child transmission (PMTCT) of HIV program offered by the Kenyan Ministry of Health and Médecins Sans Frontières in the informal settlement of Kibera, Nairobi. This study aimed to explore barriers to enrolling and remaining engaged in PMTCT services throughout the pregnancy and postpartum periods. Qualitative data from 31 focus group discussions and 35 in-depth interviews across six stakeholder groups that included women, men, and PMTCT service providers were analyzed. Using an inductive exploratory approach, four researchers coded the data and identified key themes. Five themes emerged from the data that may influence attrition from PMTCT service in this setting: 1) HIV in the context of Kibera, 2) knowledge of HIV status, 3) knowledge of PMTCT, 4) disclosure of HIV status, and 5) male partner support for PMTCT services. A new HIV diagnosis during pregnancy immediately triggered an ongoing risk assessment of perceived hazards in the home, community, and clinic environments that could occur as a result of female participation in PMTCT services. Male partners were a major influence in this risk assessment, but were generally unaware of PMTCT services. To preserve relationships with male partners, meet community expectations of womanhood, and maintain confidentiality while following recommendations of healthcare providers, women had to continuously weigh the risks and benefits of PMTCT services and interventions. Community-based HIV testing and PMTCT education, male involvement in antenatal care, and counseling customized to assist each woman in her own unique risk assessment, may improve uptake of and retention in care and optimize the HIV prevention benefit of PMTCT interventions.

    Eliminating mother-to-child transmission of HIV (EMTCT), defined as ≤50 infant HIV infections per 100 000 live births, is a global priority. Since 2011 policies to prevent mother-to-child transmission of HIV (PMTCT) shifted from maternal antiretroviral (ARV) treatment or prophylaxis contingent on CD4 cell count to lifelong maternal ARV treatment (cART). We sought to measure progress with early (4-8 weeks postpartum) MTCT prevention and elimination, 2011-2013, at national and sub-national levels in South Africa, a high antenatal HIV prevalence setting ( ≈ 29%), where early MTCT was 3.5% in 2010. Two surveys were conducted (August 2011-March 2012 and October 2012-May 2013), in 580 health facilities, randomly selected after two-stage probability proportional to size sampling of facilities (the primary sampling unit), to provide valid national and sub-national-(provincial)-level estimates. Data collectors interviewed caregivers of eligible infants, reviewed patient-held charts, and collected infant dried blood spots (iDBS). Confirmed positive HIV enzyme immunoassay (EIA) and positive total HIV nucleic acid polymerase chain reaction (PCR) indicated infant HIV exposure or infection, respectively. Weighted survey analysis was conducted for each survey and for the pooled data. National data from 10 106 and 9120 participants were analyzed (2011-12 and 2012-13 surveys respectively). Infant HIV exposure was 32.2% (95% confidence interval (CI) 30.7-33.6%), in 2011-12 and 33.1% (95% CI 31.8-34.4%), provincial range of 22.1-43.6% in 2012-13. MTCT was 2.7% (95% CI 2.1%-3.2%) in 2011-12 and 2.6% (95% CI 2.0-3.2%), provincial range of 1.9-5.4% in 2012-13. HIV-infected ARV-exposed mothers had significantly lower unadjusted early MTCT (2.0% [2011-12: 1.6-2.5%; 2012-13:1.5-2.6%]) compared to HIV-infected ARV-naive mothers [10.2% in 2011-12 (6.5-13.8%); 9.2% in 2012-13 (5.6-12.7%)]. Pooled analyses demonstrated significantly lower early MTCT among exclusive breastfeeding

    Full Text Available Introduction Using spatial–temporal analyses to understand coverage and trends in elimination of mother-to-child transmission of HIV (e-MTCT efforts may be helpful in ensuring timely services are delivered to the right place. We present spatial–temporal analysis of seven years of HIV early infant diagnosis (EID data collected from 12 districts in western Kenya from January 2007 to November 2013, during pre-Option B+ use. Methods We included in the analysis infants up to one year old. We performed trend analysis using extended Cochran–Mantel–Haenszel stratified test and logistic regression models to examine trends and associations of infant HIV status at first diagnosis with: early diagnosis (<8 weeks after birth, age at specimen collection, infant ever having breastfed, use of single dose nevirapine, and maternal antiretroviral therapy status. We examined these covariates and fitted spatial and spatial–temporal semiparametric Poisson regression models to explain HIV-infection rates using R-integrated nested Laplace approximation package. We calculated new infections per 100,000 live births and used Quantum GIS to map fitted MTCT estimates for each district in Nyanza region. Results Median age was two months, interquartile range 1.5–5.8 months. Unadjusted pooled positive rate was 11.8% in the seven-years period and declined from 19.7% in 2007 to 7.0% in 2013, p < 0.01. Uptake of testing ≤8 weeks after birth was under 50% in 2007 and increased to 64.1% by 2013, p < 0.01. By 2013, the overall standardized MTCT rate was 447 infections per 100,000 live births. Based on Bayesian deviance information criterion comparisons, the spatial–temporal model with maternal and infant covariates was best in explaining geographical variation in MTCT. Discussion Improved EID uptake and reduced MTCT rates are indicators of progress towards e-MTCT. Cojoined analysis of time and covariates in a spatial context provides a robust approach for explaining

    The rate of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) type 1 is as low as 0.5% in non-breast-feeding mothers who delivered at term while receiving antiretroviral therapy with a plasma viral load <500 copies/mL. This situation accounted for 20% of the infected children born during the period 1997-2006 in the French Perinatal Cohort. We aimed to identify factors associated with such residual transmission risk. We performed a case-control study nested in the aforementioned subpopulation of the French Perinatal Cohort. Nineteen case patients (transmitters) and 60 control subjects (nontransmitters) were included. Case patients and control subjects did not differ by geographical origin, gestational age at HIV diagnosis, type of antiretroviral therapy received, or elective Cesarean delivery. Case patients were less often receiving treatment at the time that they conceived pregnancy than control subjects (16% vs 45%; P=.017). A lower proportion of case patients had a viral load <500 copies/mL, compared with control subjects, at 14 weeks (0% vs 38.1%; P=.02), 28 weeks (7.7% vs 62.1%; P=.005), and 32 weeks: (21.4% vs 71.1%; P=.004). The difference remained significant when we restricted analysis to the 10 of 16 intrapartum transmission cases. In a multivariate analysis at 30+/-4 weeks adjusted for viral load, CD4(+) T cell count, and time at antiretroviral therapy initiation, viral load was the only factor independently associated with MTCT of HIV (adjusted odds ratio, 23.2; 95% confidence interval, 3.5-553; P<.001). Early and sustained control of viral load is associated with a decreasing residual risk of MTCT of HIV-1. Guidelines should take into account not only CD4(+) T cell count and risk of preterm delivery, but also baseline HIV-1 load for deciding when to start antiretroviral therapy during pregnancy.

    Achieving the goal of eliminating mother-to-child HIV transmission (MTCT) necessitates increased access to antiretroviral therapy (ART) for HIV-infected pregnant women. Option B provides ART through pregnancy and breastfeeding, whereas Option B+ recommends continuous ART regardless of CD4 count, thus potentially reducing MTCT during future pregnancies. Our objective was to compare maternal and pediatric health outcomes and cost-effectiveness of Option B+ versus Option B in Ghana. A decision-analytic model was developed to simulate HIV progression in mothers and transmission (in utero, during birth, or through breastfeeding) to current and all future children. Clinical parameters, including antenatal care access and fertility rates, were estimated from a retrospective review of 817 medical records at two hospitals in Ghana. Additional parameters were obtained from published literature. Modeled outcomes include HIV infections averted among newborn children, quality-adjusted life-years (QALYs), and cost-effectiveness ratios. HIV-infected women in Ghana have a lifetime average of 2.3 children (SD 1.3). Projected maternal life expectancy under Option B+ is 16.1 years, versus 16.0 years with Option B, yielding a gain of 0.1 maternal QALYs and 3.2 additional QALYs per child. Despite higher initial ART costs, Option B+ costs $785/QALY gained, a value considered very cost-effective by World Health Organization benchmarks. Widespread implementation of Option B+ in Ghana could theoretically prevent up to 668 HIV infections among children annually. Cost-effectiveness estimates remained favorable over robust sensitivity analyses. Although more expensive than Option B, Option B+ substantially reduces MTCT in future pregnancies, increases both maternal and pediatric QALYs, and is a cost-effective use of limited resources in Ghana.

    In 2014, the World Health Organization (WHO) initiated a process for validation of the elimination of mother-to-child transmission (EMTCT) of HIV and syphilis by countries. For the first time in such a process for the validation of disease elimination, WHO introduced norms and approaches that are grounded in human rights, gender equality, and community engagement. This human rights-based validation process can serve as a key opportunity to enhance accountability for human rights protection by evaluating EMTCT programs against human rights norms and standards, including in relation to gender equality and by ensuring the provision of discrimination-free quality services. The rights-based validation process also involves the assessment of participation of affected communities in EMTCT program development, implementation, and monitoring and evaluation. It brings awareness to the types of human rights abuses and inequalities faced by women living with, at risk of, or affected by HIV and syphilis, and commits governments to eliminate those barriers. This process demonstrates the importance and feasibility of integrating human rights, gender, and community into key public health interventions in a manner that improves health outcomes, legitimizes the participation of affected communities, and advances the human rights of women living with HIV.

    Full Text Available Background: Developed by the World Health Organization (WHO and partners, the correct adaptation and implementation of the global guidelines on prevention of mother-to-child transmission (PMTCT of HIV is critical. This study explored the challenges that health workers face implementing WHO’s PMTCT guidelines, and the experiences of HIV-positive clients receiving these services. Methods: We interacted with 14 health professionals, and 16 PMTCT clients through in-depth interviews. Four of seven PMTCT sites within the Accra Metropolis were purposively included. Interviews were tape-recorded, transcribed, analyzed, and then sorted into themes. Results: Health workers had challenges translating PMTCT guidelines into useful messages for their clients. Their counselling was often prescriptive. Counselors identified inadequate in-service training as a key reason for their outdated and inconsistent messages. HIV-positive clients exhibited general knowledge about the importance of doing exclusive breast-feeding for the first six months of life. Clients had confidence in antiretroviral for PMTCT. However, deeply rooted socio-cultural practices and the attitudes of counselors remain challenges to clients. Conclusions and Global Health Implications: Counselors require refresher training which addresses, among other things, long-held socio-cultural practices. Publicizing these challenges will prod policy makers and program implementers to develop strategies that address the challenges both locally and globally.

    South Africa (SA) has the highest number of women infected with HIV and AIDS during pregnancy, which results in more than 70 000 infected babies being born each year AIDS is the major contributor to maternal and child morbidities and mortalities in the country. To combat this, the SA government has developed a national policy to prevent mother-to-child HIV transmission (PMTCT). However, for effective implementation of this policy, there is a dire need for a competent, skilled health worker to render the service. In response to this, the School of Nursing at the University of the Western Cape has integrated PMTCT competencies into the undergraduate Bachelor of Nursing Science curriculum. In this paper, we described teaching and learning approaches used to integrate PMTCT competencies, including the skills laboratory methodology and case-based learning, as well as a portfolio of evidence assessment tool. A quantitative descriptive design was used to analyse data collected from students in regard to assessment of PMTCT competencies achieved. The study used the conceptual framework of Lenburg's competency outcomes and performance assessment model, which focuses on competency development and assessment in a clinical environment. HIV competencies, including PMTCT, should be integrated both theoretically and at service delivery into other nursing and midwifery competencies, including assessment strategies. Provincial policies in provision of antiretrovirals by nurses and midwives become barriers to successful implementation of PMTCT, resulting in limited learning opportunities for students to practice PMTCT competencies. Further research is required to assess an attribute, affect, which is another prong for competencies.

    Full Text Available Objectives To evaluate efficacy of the antenatal, intra-partum and post-natal antiretroviral components of a public service Prevention of Mother to Child (MTCT program in infants. Design Analysis of prospectively collected screening data of demographic and MTCT-related interventions and HIV-infection status of infants identified through HIV-specific DNA polymerase chain reaction. Setting Tygerberg Children’s Hospital, Western Cape Province, South Africa. Subjects HIV-infected women and their infants identified through participation in a public service MTCT program were referred for possible participation in a prospective study of isoniazid prophylaxis. Interventions Key components of the Program include voluntary counselling and testing, zidovudine to the mother from between 28 and 34 weeks gestation and to the newborn infant for the first week, single dose nevirapine to the mother in labour and the newborn shortly after birth and free formula for 6 months. Main Outcome Measures Number and percentage of HIV-infected infants and extent of exposure to antenatal, intrapartum and post-natal antiretrovirals. Results Of 656 infants with a median age of 12.6 weeks, screened between April 1st 2005 through May 2006, 39 were HIV-infected giving a transmission rate of 5.9% (95% CI: 4.4% - 8.0%. Antenatal prophylaxis was significantly associated with reduced transmission (OR: 0.43 (95% CI: 0.21 - 0.94 as opposed to intrapartum and postpartum components (p=0.85 and p=0.84, respectively. In multivariable analysis the antenatal component remained significant (OR=0.40 (95% CI 0.19 - 0.90. Conclusions The antenatal phase is the most important antiretroviral component of the MTCT program, allowing most opportunity for intervention.

    Full Text Available Objectives: There has been little focus on quality of care provided in prevention of mother-to-child transmission of HIV (PMTCT services in South Africa. We assessed quality of care in PMTCT services in Soweto, South Africa, focusing on knowledge and experiences of healthcare workers and HIV-infected pregnant women accessing the services. Methods: A cross-sectional survey was conducted between November and December 2009. A total of 201 HIV-infected pregnant women and 80 healthcare workers, from 10 antenatal clinics, were interviewed using standardised questionnaires. Results: The median gestational age at first antenatal visit was 20 weeks and 32 weeks at the time of the interview. The majority of the women, 71.5%, discovered that they were HIV-infected in the index pregnancy, and 87.9% disclosed their HIV status. Overall, 97.5% received counselling and 33.5% were members of a support group. Knowledge of antenatal and intrapartum PMTCT interventions was correct in 62.7% and 43.3% of the women, respectively. Support group membership and current use of antiretroviral prophylaxis did not impact on the quality of knowledge. Of the healthcare workers, 43.8% were professional nurses and 37.5% were lay counsellors. The majority, 80.0%, felt satisfied with their knowledge of PMTCT guidelines and 96.3% felt competent in managing HIV-infected pregnant women. Yet, there were important deficiencies in knowledge of the guidelines. Conclusion: In our study, knowledge of PMTCT interventions was low in both clients and healthcare workers. These findings point to a need to improve quality of care in PMTCT services, especially with increasingly complex PMTCT interventions recommended by international policies.

    Full Text Available Background: When new guidelines for existing programmes are introduced, it is often the clinicians tasked with the execution of the guidelines who bear the brunt of the changes. Frequently their opinions are not sought. In this study, the researcher interviewed registered nurses working in the field of the prevention of mother-to-child transmission (PMTCT of human immunodeficiency virus (HIV to gain an understanding of their perspectives on the changes introduced to the guidelines. The guideline changes in 2014 were to move from the World Health Organization (WHO Option B to Option B + which prescribes lifelong antiretroviral therapy (ART for all HIV-positive pregnant women regardless of CD4 cell count. Objective: To determine what the registered nurses’ perspectives are on the PMTCT programme as implemented at four PHC facilities in the Limpopo Province. Method: For this qualitative investigation, a descriptive research design was implemented. The data were collected during semi-structured interviews with nurses from four primary healthcare facilities in the Limpopo Province of South Africa. Data were analysed using thematic analysis. Results: Challenges preventing effective implementation (e.g. increased workloads, viz. staff shortages; poor planning of training; equipment and medication shortages and long lead times; poor patient education were identified. Conclusion: In spite of the successes of the PMTCT programme, considerable challenges still prevail; lack of patient education, poor facilities management and staff shortages could potentially influence the implementation of the PMTCT guidelines negatively.

    Over the past 10 years substantial progress has been made in the implementation of prevention of mother-to-child transmission of HIV (PMTCT) interventions in Sub-Saharan Africa (SSA). In spite of this, new pediatric infections remain unacceptably high, contributing the majority (>90%) of the estimated 390,000 infections globally in 2010; and yet prolonged breastfeeding remains the norm and crucial to overall infant survival. However, there is reason for optimism given the 2010 World Health Organization PMTCT recommendations: to start HIV infected pregnant women with CD4 cell counts less than 350 cells/mm(3) on lifelong antiretroviral therapy (ART); and for mothers not eligible for ART to provide efficacious maternal and/or infant PMTCT antiretroviral (ARV) regimens to be taken during pregnancy, labor/delivery and through breastfeeding. Current attention is on whether to extend maternal ARVs for life once triple ARV PMTCT regimens are started. To dramatically reduce new pediatric infections, individual countries need to politically commit to rapid scale-up of a multi-pronged PMTCT effort: including primary prevention to reduce HIV incidence among women of reproductive age; increased access to family planning services; HIV screening of all pregnant and breastfeeding women followed by ART or ARVs for PMTCT; and comprehensive care for HIV affected families. Efforts to achieve population-level success in SSA need to critically address operational issues and challenges to implementation (health system) and utilization (social, economic and cultural barriers), at the country, health centre and client level that have led to the relatively slow progress in the scale-up of PMTCT strategies.

    2011-08-01

    The World Health Organization released recommendations on treatment, prevention, and infant feeding practices within the context of HIV infection based on the "latest scientific evidence" available. The "Rapid Advice" document anticipates the release of official HIV Prevention-of-Mother-to-Child Transmission guidelines. As investigators involved in public health programs providing HIV care in sub-Saharan Africa, we are concerned about the ramifications of specific recommendations, often viewed as dogma by policy makers in this setting. The recommendation that CD4 cell counts be available antenatally so that decisions can be made regarding maternal antiretroviral eligibility is problematic because the ability to measure CD4 cells is nonexistent in many African health centers. As a result, antiretroviral treatment initiation in pregnancy will either be unnecessarily delayed or patients in need of treatment may receive prolonged courses of monotherapy. It is critical that exceptions be made for populations without access to flow cytometry. Another point of concern is that the massive unrestricted use of efavirenz during pregnancy is encouraged. Given that surveillance of pregnancy outcomes is not routinely performed in such settings and in light of the teratogenic potential of efavirenz (contraindicated during the first trimester in developed countries), we are concerned that its indiscriminate use will lead to further problems in vulnerable populations. Another premature recommendation is the use of daily administration of nevirapine to HIV-exposed infants throughout the entire duration of breastfeeding. Results of clinical trials documenting the efficacy of this approach for extended periods of time are not yet available. Single dose nevirapine has been shown to compromise future treatment options in HIV-infected women and infants. In addition, the long-term safety profile of this agent in immune-competent infants has not been established. In summary, although the

    Full Text Available Rwanda's National PMTCT program aims to achieve elimination of new HIV infections in children by 2015. In November 2010, Rwanda adopted the WHO 2010 ARV guidelines for PMTCT recommending Option B (HAART for all HIV-positive pregnant women extended throughout breastfeeding and discontinued (short course-HAART only for those not eligible for life treatment. The current study aims to assess the cost-effectiveness of this policy choice.Based on a cohort of HIV-infected pregnant women in Rwanda, we modelled the cost-effectiveness of six regimens: dual ARV prophylaxis with either 12 months breastfeeding or replacement feeding; short course HAART (Sc-HAART prophylaxis with either 6 months breastfeeding, 12 months breastfeeding, or 18 months breastfeeding; and Sc-HAART prophylaxis with replacement feeding. Direct costs were modelled based on all inputs in each scenario and related unit costs. Effectiveness was evaluated by measuring HIV-free survival at 18 months. Savings correspond to the lifetime costs of HIV treatment and care avoided as a result of all vertical HIV infections averted.All PMTCT scenarios considered are cost saving compared to "no intervention." Sc-HAART with 12 months breastfeeding or 6 months breastfeeding dominate all other scenarios. Sc-HAART with 12 months breastfeeding allows for more children to be alive and HIV-uninfected by 18 months than Sc-HAART with 6 months breastfeeding for an incremental cost per child alive and uninfected of 11,882 USD. This conclusion is sensitive to changes in the relative risk of mortality by 18 months for exposed HIV-uninfected children on replacement feeding from birth and those who were breastfed for only 6 months compared to those breastfeeding for 12 months or more.Our findings support the earlier decision by Rwanda to adopt WHO Option B and could inform alternatives for breastfeeding duration. Local contexts and existing care delivery models should be part of national policy decisions.

    Objective To estimate the cost-effectiveness of prevention of mother to child transmission (MTCT) of HIV with lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women (‘Option B+’) compared to ART during pregnancy or breastfeeding only unless clinically indicated (‘Option B’). Design Mathematical modelling study of first and second pregnancy, informed by data from the Malawi Option B+ programme. Methods Individual-based simulation model. We simulated cohorts of 10,000 women and their infants during two subsequent pregnancies, including the breastfeeding period, with either Option B+ or B. We parameterised the model with data from the literature and by analysing programmatic data. We compared total costs of ante-natal and post-natal care, and lifetime costs and disability-adjusted life-years (DALYs) of the infected infants between Option B+ and Option B. Results During the first pregnancy, 15% of the infants born to HIV-infected mothers acquired the infection. With Option B+, 39% of the women were on ART at the beginning of the second pregnancy, compared to 18% with Option B. For second pregnancies, the rates MTCT were 11.3% with Option B+ and 12.3% with Option B. The incremental cost-effectiveness ratio comparing the two options ranged between about US$ 500 and US$ 1300 per DALY averted. Conclusion Option B+ prevents more vertical transmissions of HIV than Option B, mainly because more women are already on ART at the beginning of the next pregnancy. Option B+ is a cost-effective strategy for PMTCT if the total future costs and lost lifetime of the infected infants are taken into account. PMID:26691682

    Full Text Available Abstract Background Although highly effective prevention interventions exist, the epidemic of paediatric HIV continues to challenge control efforts in resource-limited settings. We reviewed the cost-effectiveness of interventions to prevent mother-to-child transmission (MTCT of HIV in low- and middle-income countries (LMICs. This article presents syntheses of evidence on the costs, effects and cost-effectiveness of HIV MTCT strategies for LMICs from the published literature and evaluates their implications for policy and future research. Methods Candidate studies were identified through a comprehensive database search including PubMed, Embase, Cochrane Library, and EconLit restricted by language (English or French, date (January 1st, 1994 to January 17th, 2011 and article type (original research. Articles reporting full economic evaluations of interventions to prevent or reduce HIV MTCT were eligible for inclusion. We searched article bibliographies to identify additional studies. Two authors independently assessed eligibility and extracted data from studies retained for review. Study quality was appraised using a modified BMJ checklist for economic evaluations. Data were synthesised in narrative form. Results We identified 19 articles published in 9 journals from 1996 to 2010, 16 concerning sub-Saharan Africa. Collectively, the articles suggest that interventions to prevent paediatric infections are cost-effective in a variety of LMIC settings as measured against accepted international benchmarks. In concentrated epidemics where HIV prevalence in the general population is very low, MTCT strategies based on universal testing of pregnant women may not compare well against cost-effectiveness benchmarks, or may satisfy formal criteria for cost-effectiveness but offer a low relative value as compared to competing interventions to improve population health. Conclusions and Recommendations Interventions to prevent HIV MTCT are compelling on economic

    Full Text Available BACKGROUND: Zambia adopted Option A for prevention of mother-to-child transmission of HIV (PMTCT in 2010 and announced a move to Option B+ in 2013. We evaluated the uptake, outcomes, and costs of antenatal, well-baby, and PMTCT services under routine care conditions in Zambia after the adoption of Option A. METHODS: We enrolled 99 HIV-infected/HIV-exposed (index mother/baby pairs with a first antenatal visit in April-September 2011 at four study sites and 99 HIV-uninfected/HIV-unexposed (comparison mother/baby pairs matched on site, gestational age, and calendar month at first visit. Data on patient outcomes and resources utilized from the first antenatal visit through six months postpartum were extracted from site registers. Costs in 2011 USD were estimated from the provider's perspective. RESULTS: Index mothers presented for antenatal care at a mean 23.6 weeks gestation; 55% were considered to have initiated triple-drug antiretroviral therapy (ART based on information recorded in site registers. Six months postpartum, 62% of index and 30% of comparison mother/baby pairs were retained in care; 67% of index babies retained had an unknown HIV status. Comparison and index mother/baby pairs utilized fewer resources than under fully guideline-concordant care; index babies utilized more well-baby resources than comparison babies. The average cost per comparison pair retained in care six months postpartum was $52 for antenatal and well-baby services. The average cost per index pair retained was $88 for antenatal, well-baby, and PMTCT services and increased to $185 when costs of triple-drug ART services were included. CONCLUSIONS: HIV-infected mothers present to care late in pregnancy and many are lost to follow up by six months postpartum. HIV-exposed babies are more likely to remain in care and receive non-HIV, well-baby care than HIV-unexposed babies. Improving retention in care, guideline concordance, and moving to Option B+ will result in

We aimed to (i) describe how Option B+ is provided in health facilities in the South East Zone in Malawi, identifying the diverse approaches to service organization (the "model of care") and (ii) explore associations between the "model of care" and health facility-level uptake and retention rates for pregnant women identified as HIV-positive at antenatal (ANC) clinics. A health facility survey was conducted in all facilities providing PMTCT/antiretroviral therapy (ART) services in six of Malawi's 28 districts to describe and compare Option B+ service delivery models. Associations of identified models with program performance were explored using facility cohort reports. Among 141 health facilities, four "models of care" were identified: A) facilities where newly identified HIV-positive women are initiated and followed on ART at the ANC clinic until delivery; B) facilities where newly identified HIV-positive women receive only the first dose of ART at the ANC clinic, and are referred to the ART clinic for follow-up; C) facilities where newly identified HIV-positive women are referred from ANC to the ART clinic for initiation and follow-up of ART; and D) facilities serving as ART referral sites (not providing ANC). The proportion of women tested for HIV during ANC was highest in facilities applying Model A and lowest in facilities applying Model B. The highest retention rates were reported in Model C and D facilities and lowest in Model B facilities. In multivariable analyses, health facility factors independently associated with uptake of HIV testing and counselling (HTC) in ANC were number of women per HTC counsellor, HIV test kit availability, and the "model of care" applied; factors independently associated with ART retention were district location, patient volume and the "model of care" applied. A large variety exists in

    Full Text Available Antenatal invasive obstetric procedures may be diagnostic or therapeutic, and are performed at different stages of pregnancy for various indications. The commonest indication for an invasive procedure during pregnancy is for fetal karyotyping when a chromosomal abnormality or a genetic defect is suspected, either from the couple’s history or from ultrasound assessment of the fetus. Other less common but equally important indications may be diagnostic (fetoscopy, fetal tissue sampling, estimation of fetal haemoglobin or therapeutic (aspiration of various fetal cavities, fetal blood transfusion and embryo reductions. In a high HIV prevalence setting like South Africa, a significant proportion of pregnant women in need of invasive procedures will be HIV-infected.

    To identify the effect of highly active anti-retroviral therapy (HAART) on prevention of mother to child transmission (PMTCT) of HIV and on infant growth and development. A total of 16 HIV-infected women or pregnant women selected in this study received HAART before or 18 - 24 weeks after pregnancy. The treatment included taking Zidovudine (AZT) 0.3 g each time, twice a day, Lamivudine (3TC) 0.3 g each time, once a day and Nevirapine (NVP) 0.2 g each time, twice a day or Efavirenz (EFV) 0.6 g each time, once a day, as well as labor intervention and artificial feeding. The growth index for 17 infants from HIV-infected mothers (experimental group) and 16 normal infants (control group) were observed for 18 months. Neonatal hemoglobin (Hb), liver and kidney function, serum iron and calcium were detected at neonatal period and at 12(th) month, respectively. All the pregnant women were in good conditions and had tolerance with HAART. The birth weight, length and Apgar score of the newborns in the experimental group were (3.5 ± 0.9) kg, (54.2 ± 3.8) cm and 7 - 10 scores respectively, however those in the control group were (3.6 ± 0.8) kg, (55.6 ± 3.6) cm and 8 - 10 scores (t(weight) = 1.01, t(length) = 6.98, P > 0.05). Weight and length of infants in experimental group were (9.36 ± 1.8) kg and (76.3 ± 2.7) cm at 12(th) month, while those in control group were (9.86 ± 2.5) kg and (76.8 ± 2.9) cm (t(weight) = 0.83, t(length) = 1.00, P > 0.05). The level of Hb in experimental group was (126.2 ± 16.7) g/L, and was (148.6 ± 20.5) g/L in control group (t = -5.89, P = 0.11). At 12(th) month, the levels of Hb and the total bilirubin (TB) were (125.9 ± 19.8) g/L and (11.7 ± 3.5) µmol/L in experimental group; and those in the control group were (130.1 ± 18.7) g/L and (13.2 ± 3.7) µmol/L (t(Hb) = -3.82, t(TB) = -2.14, P > 0.05). Serum iron and calcium were (25.4 ± 5.7) µmol/L and (26.4 ± 7.2) µmol/L at neonatal period and were (2.3 ± 0.6) mol/L and (2.8 ± 0

    Full Text Available OBJECTIVE: We assessed the 18-month effectiveness of short-course (sc antiretroviral peripartum regimens combined with alternatives to prolonged breastfeeding to prevent mother-to-child transmission (MTCT of HIV-1 in Abidjan, Côte d'Ivoire. METHODOLOGY: HIV-1 infected pregnant women received from >/=32-36 weeks of gestation scZidovudine (ZDV+/-Lamivudine (3TC+single-dose Nevirapine (sdNVP at delivery within the ANRS 1201/1202 DITRAME-Plus cohort (2001-2003. Neonates received a sdNVP+7-day ZDV prophylaxis. Two infant-feeding interventions were systematically offered free of charge: formula-feeding or exclusive shortened breastfeeding with early cessation from four months. The reference group was the ANRS 049a DITRAME cohort (1994-2000 exposed to scZDV from 36 weeks, then to prolonged breastfeeding. Pediatric HIV infection was defined by a positive plasma HIV-1 RNA at any age, or if aged >/=18 months, a positive HIV-1 serology. Turnbull estimates of cumulative transmission risks (CTR and effectiveness (HIV-free survival were compared by exposure group using a Cox model. FINDINGS: Among 926 live-born children enrolled, 107 (11.6% were HIV-infected at 18 months. CTRs were 22.3% (95% confidence interval[CI]:16-30% in the 238 ZDV long-term breastfed reference group, 15.9% (CI:10-27% in the 169 ZDV+sdNVP shortened breastfed group; 9.4% (CI:6-14% in the 195 ZDV+sdNVP formula-fed group; 6.8% (CI:4-11% in the 198 ZDV+3TC+sdNVP shortened breastfed group, and 5.6% (CI:2-10% in the 126 ZDV+3TC+sdNVP formula-fed group. Each combination had a significantly higher effectiveness than the ZDV long-term breastfed group except for ZDV+sdNVP shortened breastfed children, ranging from 51% (CI:20-70% for ZDV+sdNVP formula fed children to 63% (CI:40-80% for ZDV+3TC+NVPsd shortened breastfed children, after adjustment for maternal eligibility for antiretroviral therapy (ART, home delivery and low birth-weight.

    Full Text Available Abstract Background Prevention of Mother-to-Child Transmission of HIV (PMTCT is among the key HIV prevention strategies in Zimbabwe. A decrease in use of antenatal care (ANC services with an increase in home deliveries is affecting the coverage of PMTCT interventions in a context of accelerated economic crisis. The main objective was to evaluate acceptability and feasibility of reinforcing the role of traditional birth attendants (TBAs in family and child health services through their participation in PMTCT programmes in Zimbabwe. Methods A community based cross-sectional survey was undertaken using multistage cluster sampling in two rural districts through interviews and focus group discussions among women who delivered at home with a TBA, those who had an institutional delivery and TBAs. Results 45% of TBAs interviewed knew the principles of PMTCT and 8% delivered a woman with known HIV-positive status in previous year. Of the complete package of PMTCT services, more than 75% of TBAs agreed to participate in most activities with the exception of performing a blood test (17%, accompanying new-borns to closest health centre to receive medication (15% and assisting health centres in documentation of the link ANC-PMTCT services (18%. Women who delivered at home were less likely to have received more than one ANC service or have had contact with a health centre compared to women who delivered in a health centre (91.0% vs 72.6%; P Conclusion Although the long-term goal of ANC service delivery in Zimbabwe remains the provision of skilled delivery attendance, PMTCT programmes will benefit from complementary approaches to prevent missed opportunities. TBAs are willing to expand their scope of work regarding activities related to PMTCT. There is a need to reinforce their knowledge on MTCT prevention measures and better integrate them into the health system.

    Primary infection, seroconversion, and transmitted drug resistance (TDR) during pregnancy may influence the risk of mother-to-child-transmission (MTCT) of HIV-1 infection. This study estimated recent seroconversion, TDR rates, HIV-1 subtypes and pregnancy outcomes among 95 recently diagnosed, antiretroviral (ARV)-naïve pregnant women recruited during antenatal care in central western Brazil. Recent seroconversion was defined by BED-capture enzyme immunoassay (HIV-1 subtypes were defined by REGA and phylogenetic analyses. The median age of participants was 25 years; the median gestational age at diagnosis was 20.5 weeks. Based on serology and sequence polymorphism, recent infection was identified in 11.6% (11/95) and, 9 of them (82%), probably seroconverted during pregnancy; one MTCT case was observed among them. Three cases of stillbirth were observed among chronic infected patients (3.6%; 3/84). Moderate rate of TDR was observed (9/90, 10%, CI95% 4.7-18.1%). Subtype B was 60% (54/90), 13.3% (12/90) was subtype C, 6.7% (6/90) was subtype F1. Recombinant B(PR) /F1(RT) and F1(PR) /B(RT) viruses comprised 15.5% (14/90); B(PR) /C(RT) mosaics represented 4.4% (4/90). Seroconversion during pregnancy, late presentation to antenatal care and moderate TDR identified in this study represent significant challenges for the MTCT elimination. J. Med.

    Objectives To investigate and synthesize reasons for low access, initiation and adherence to antiretroviral drugs by mothers and exposed babies for prevention of mother-to-child transmission (PMTCT) of HIV in sub-Saharan Africa. Methods A systematic literature review was conducted. Four databases were searched (Medline, Embase, Global Health and Web of Science) for studies conducted in sub-Saharan Africa from January 2000 to September 2012. Quantitative and qualitative studies were included that met pre-defined criteria. Antiretroviral (ARV) prophylaxis (maternal/infant) and combination antiretroviral therapy (ART) usage/registration at HIV care and treatment during pregnancy were included as outcomes. Results Of 574 references identified, 40 met the inclusion criteria. Four references were added after searching reference lists of included articles. Twenty studies were quantitative, 16 were qualitative and eight were mixed methods. Forty-one studies were conducted in Southern and East Africa, two in West Africa, none in Central Africa and one was multi-regional. The majority (n=25) were conducted before combination ART for PMTCT was emphasized in 2006. At the individual-level, poor knowledge of HIV/ART/vertical transmission, lower maternal educational level and psychological issues following HIV diagnosis were the key barriers identified. Stigma and fear of status disclosure to partners, family or community members (community-level factors) were the most frequently cited barriers overall and across time. The extent of partner/community support was another major factor impeding or facilitating the uptake of PMTCT ARVs, while cultural traditions including preferences for traditional healers and birth attendants were also common. Key health-systems issues included poor staff-client interactions, staff shortages, service accessibility and non-facility deliveries. Conclusions Long-standing health-systems issues (such as staffing and service accessibility) and community

    Full Text Available Abstract Background Uptake of and adherence to the prevention of mother to child transmission of HIV (PMTCT interventions are a challenge to most women if there is no male partner involvement. Organizations which include the National AIDS Council and the Zimbabwe AIDS Prevention Project- University of Zimbabwe have been working towards mobilizing men for couple HIV testing and counseling (HTC in antenatal care (ANC. In 2013, Midlands province had 19 % males who were tested together with their partners in ANC, an increase by 9 % from 2011. However, this improvement was still far below the national target, hence this study was conducted to determine the associated factors. Methods A1:1 unmatched case control study was conducted. A case was a man who did not receive HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. A control was a man who received HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. Simple random sampling was used to select 112 cases and 112 controls. Epi Info statistical software was used to analyze data. Written informed consent was obtained from each study participant. Results Independent factors that predicted male involvement in PMTCT were: having been previously tested as a couple (aOR 0.22, 95 % CI = 0.12, 0.41 and having time to visit the clinic (aOR 0.41, 95 % CI = 0.21, 0.80. Being afraid of knowing one’s HIV status (aOR 2.22, 95 % CI = 1.04, 4.76 was independently associated with low male involvement in PMTCT. Conclusion Multiple factors were found to be associated with male involvement in PMTCT. Routine PMTCT educational campaigns in places where men gather, community based couple HTC and accommodating the working class during weekends are essential in fostering male involvement in PMTCT thereby reducing HIV transmission to the baby.

    The prevention of mother-to-child transmission (PMTCT) of HIV requires innovative solutions. Although routine monitoring is effective in some areas, standardized and easy-to-scale solutions to identify and monitor pregnant women, test them for HIV, and treat them and their children is still lacking. Mobile health (mHealth) offers opportunities for surveillance and reporting in rural areas of low- and middle-income countries. The aim of this study was to document the preliminary impacts of the Tanzania Health Information Technology (T-HIT) system mHealth intervention aimed at health workers for PMTCT care delivery and capacity building in a rural area of Tanzania. We developed T-HIT as a tablet-based system for an electronic data collection system designed to capture and report PMTCT data during antenatal, delivery, and postnatal visits in Misungwi, Tanzania. T-HIT was tested by health workers in a pilot randomized trial comparing seven sites using T-HIT assigned at random to seven control sites; all sites maintained standard paper record-keeping during the pilot intervention period. We compared numbers of antenatal visits, number of HIV tests administered, and women testing positive across all sites. Health workers recorded data from antenatal visits for 1530 women; of these, 695 (45.42%) were tested for HIV and 3.59% (55/1530) tested positive. Health workers were unable to conduct an HIV test for 103 women (6.73%, 103/1530) because of lack of reagent, which is not captured on paper logs. There was no difference in the activity level for testing when comparing sites T-HIT to non-T-HIT sites. We observed a significant postintervention increase in the numbers of women testing positive for HIV compared with the preintervention period (P=.04), but this was likely not attributable to the T-HIT system. T-HIT had a high degree of acceptability and feasibility and is perceived as useful by health workers, who documented more antenatal visits during the pilot intervention

    Full Text Available Abstract Background Implementation of programs for the prevention of mother-to-child transmission (PMTCT of HIV faces a variety of barriers and challenges. The assessment of these challenges has generally been conducted in large urban health facilities. As programs expand into rural areas, the potential barriers that may be encountered there also need to be assessed. This study examines potential barriers that might affect the acceptability of interventions for PMTCT in rural and urban settings. Results Four hundred and four women at a large urban hospital and three rural clinics that had recently started implementing PMTCT were interviewed. Level of knowledge of MTCT and preference for rapid HIV testing were equally high in both areas, but rural women had a higher tendency to think that they should consult their husbands before testing, with borderline statistical significance (72% vs. 64% p = 0.09. Health facility-based deliveries were significantly lower among mothers in rural areas compared to those in the urban setting. Overall, significant predictors of willingness to test for HIV were post-primary education (OR = 3.1 95% CI 1.2, 7.7 and knowledge about rapid HIV tests (OR = 1.8, 95% CI 1.01, 3.4. The strongest predictor of willingness to accept an HIV test was the woman's perception that her husband would approve of her testing for HIV. Women who thought their husbands would approve were almost six times more likely to report a willingness to be tested compared to those who thought their husbands would not approve (OR = 5.6, 95% CI 2.8, 11.2. Conclusion Lessons learned in large urban hospitals can be generalized to rural facilities, but the lower proportion of facility-based deliveries in rural areas needs to be addressed. Same-day results are likely to ensure high uptake of HIV testing services but male spousal involvement should be considered, particularly for rural areas. Universal Primary Education will support the success of PMTCT

    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). 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. Three scenarios were compared to assess the individual contributions of stigma, non-stigma related barriers, and drug ineffectiveness on the overall number of infant infections. Uncertainty analysis was used to estimate plausible ranges. The model follows the guidelines in place in 2010 when the data were extracted (WHO Option A), and compares this with model results had Option B+ been implemented at the time. The model estimated under Option A, 35% of infant infections being attributed to stigma. This compares to 51% of total infections had Option B+ been implemented in 2010. Under Option B+, the model estimated fewer infections than Option A, due to the availability of more effective drugs. Only 8% (Option A) and 9% (Option B+) of infant infections were attributed to drug ineffectiveness, with the trade-off in the proportion of infections being between stigma and non-stigma-related barriers. The model demonstrates that while the effect of stigma on retention of women at any given stage along the cascade can be relatively small, the cumulative effect can be large. Reducing stigma may be critical in reaching MTCT elimination targets, because as countries improve supply-side factors, the relative impact of stigma becomes greater. The cumulative nature of the PMTCT cascade results in stigma having a large effect, this feature may be harnessed for efficiency in investment by prioritizing interventions that can affect multiple

    Full Text Available Abstract Background In the Kilimanjaro region the mother-in-law has traditionally had an important role in matters related to reproduction and childcare. The aim of this study was to explore the role of the mothers-in-law in prevention of mother-to-child transmission (PMTCT service utilization and adherence to infant feeding guidelines. Methods The study was conducted during 2007-2008 in rural and urban areas of Moshi district in the Kilimanjaro region of Tanzania. Mixed methods were used and included focus group discussions with mothers-in-law, mothers and fathers; in-depth interviews with mothers-in-law, mothers, fathers and HIV-infected mothers, and a survey of 446 mothers bringing their four-week-old infants for immunisation at five reproductive and child health clinics. Results The study demonstrated that the mother-in-law saw herself as responsible for family health issues in general and child care in particular. However she received limited trust, and couples, in particular couples living in urban areas, tended to exclude her from decisions related to childbearing and infant feeding. Mothers-in-law expected their daughters-in-law to breastfeed in a customary manner and were generally negative towards the infant feeding methods recommended for HIV-infected mothers; exclusive replacement feeding and exclusive breastfeeding. Conclusions Decreasing influence of the mother-in-law and increasing prominence of the conjugal couples in issues related to reproduction and child care, reinforce the importance of continued efforts to include male partners in the PMTCT programme. The potential for involving mothers-in-law in the infant feeding component, where she still has influence in some areas, should be further explored.

    Despite large investments to prevent mother-to-child-transmission (PMTCT), pediatric HIV elimination goals are not on track in many countries. The Systems Analysis and Improvement Approach (SAIA) study was a cluster randomized trial to test whether a package of systems engineering tools could strengthen PMTCT programs. We sought to (1) define core and adaptable components of the SAIA intervention, and (2) explain the heterogeneity in SAIA's success between facilities. The Consolidated Framework for Implementation Research (CFIR) guided all data collection efforts. CFIR constructs were assessed in focus group discussions and interviews with study and facility staff in 6 health facilities (1 high-performing and 1 low-performing site per country, identified by study staff) in December 2014 at the end of the intervention period. SAIA staff identified the intervention's core and adaptable components at an end-of-study meeting in August 2015. Two independent analysts used CFIR constructs to code transcripts before reaching consensus. Flow mapping and continuous quality improvement were the core to the SAIA in all settings, whereas the PMTCT cascade analysis tool was the core in high HIV prevalence settings. Five CFIR constructs distinguished strongly between high and low performers: 2 in inner setting (networks and communication, available resources) and 3 in process (external change agents, executing, reflecting and evaluating). The CFIR is a valuable tool to categorize elements of an intervention as core versus adaptable, and to understand heterogeneity in study implementation. Future intervention studies should apply evidence-based implementation science frameworks, like the CFIR, to provide salient data to expand implementation to other settings.

    Full Text Available Abstract Background Detection of maternal HIV infection early in pregnancy is critical for prevention of mother to child transmission of HIV/AIDS. Most efforts have focused on VCT as the primary means of encouraging people to become aware of their HIV status. However, its uptake is low in many parts of sub-Saharan Africa including Ethiopia. Provider-initiated HIV testing and counseling provides a critical opportunity to diagnose HIV infection, to begin chronic care, and to prevent mother to child transmission. However, little is known about its acceptance and associated factors among pregnant women in the country and particularly in the present study area. Methods Health institution based cross-sectional quantitative study was conducted in Gondar town from July 22-August 18, 2010. A total of 400 pregnant women were involved in the study using stratified sampling technique and multiple logistic regression analysis was employed using SPSS version 16. Results A total of 400 pregnant women actively participated in this study and 330 (82.5% of them accepted provider-initiated HIV testing and counseling to be tested for HIV and 70(17.5% of them refused. Acceptance of provider-initiated HIV testing and counseling was positively associated with greater number of antenatal care visits [Adj. OR (95%CI=2.64(1.17, 5.95], residing in the urban areas[Adj. OR (95%CI=2.85(1.10, 7.41], having comprehensive knowledge on HIV [Adj. OR (95%CI=4.30(1.72, 10.73], positive partners reaction for HIV positive result [Adj.

OR (95%CI=3.27(1.34, 7.94], but negatively associated with increased maternal age and education level. Conclusion Utilization of provider-initiated HIV testing and counseling during antenatal care was relatively high among pregnant women in Gondar town. Couple counseling and HIV testing should be strengthened to promote provider-initiated HIV

    Prevention of mother-to-child transmission (PMTCT) of HIV is a life-saving public health intervention. Sub-Saharan African (SSA) countries have made significant progress in the programme, but little is known about the strategies used by them to eliminate mother-to-child transmission of HIV. To map evidence of strategies and interventions employed by SSA in bridging the implementation gap in the rapidly changing PMTCT of HIV programme policy. Electronic search of the databases MEDLINE, PubMed and SABINET for articles published in English between 2001 and August 2016. Key words included 'Sub-Saharan African countries', 'implementation strategies', 'interventions to bridge implementation gap', 'prevention of mother-to-child transmission of HIV' and 'closing implementation gap'. Of a total of 743 articles, 25 articles that met the inclusion criteria were included in the study. Manual content analysis resulted in the identification of three categories of strategies: (1) health system (referral systems, integration of services, supportive leadership, systematic quality-improvement approaches that vigorously monitors programme performance); (2) health service delivery (task shifting, networking, shared platform for learning, local capacity building, supportive supervision); as well as (3) community-level strategies (community health workers, technology use - mHealth, family-centred approaches, male involvement, culturally appropriate interventions). There are strategies that exist in SSA countries. Future research should examine multifaceted scientific models to prioritise the highest impact and be evaluated for effectiveness and efficiency.

    To estimate the incremental cost over 5 years of a policy switch from the Option B to the Option B+ protocol for the prevention of mother-to-child transmission (PMTCT) of the human immunodeficiency virus (HIV). Data from cost studies and other published sources were used to determine the cost, per woman and per cohort (1000 breastfeeding and 1000 non-breastfeeding women), of switching from Option B (maternal triple antiretroviral [ARV] regimen during pregnancy and breastfeeding plus daily nevirapine for the infant for 6 weeks) to Option B+ (maternal triple ARV regimen initiated during pregnancy and continued for life). The variables used to model the different scenarios were maternal CD4+ T lymphocyte (CD4+ cell) count (350-500 versus > 500 cells/µl), rate of decline in CD4+ cells (average, rapid, slow), breastfeeding status (yes, no) and breastfeeding duration (12, 18 or 24 months). For women with CD4+ cell counts of 350-500 cells/µl, the incremental cost per 1000 women was 157,345 United States dollars (US$) for breastfeeding women and US$ 92,813 for non-breastfeeding women. For women with CD4+ cell counts > 500 cells/µl, the incremental cost per 1000 women ranged from US$ 363,443 to US$ 484,591 for breastfeeding women and was US$ 605,739 for non-breastfeeding women. From a cost perspective, a policy switch from Option B to Option B+ is feasible in PMTCT programme settings where resources are currently being allocated to Option B.

    Despite the documented benefits of prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) services, the uptake remains low in sub-Saharan Africa. The lack of male involvement (MI) may be one of the reasons for this. However, there are limited data on strategies for MI in PMTCT. The objective of this study was to identify strategies that may promote MI in PMTCT services in antenatal care (ANC) services in Blantyre, Malawi. An exploratory qualitative study was conducted from December 2012 to January 2013 at South Lunzu Health Centre (SLHC) in Blantyre, Malawi. It consisted of six face-to-face key informant interviews (KIIs) with healthcare workers and four focus group discussions (FGDs) with 18 men and 17 pregnant women attending ANC at SLHC. The FGDs were divided according to sex and age. All FGDs and KIIs were digitally recorded and simultaneously transcribed and translated verbatim into English. Data were analyzed using thematic content analysis. Three major themes with several subcategories emerged. Theme 1 was a gatekeeping strategy with two subcategories: (1) healthcare workers refusing service provision to women accessing antenatal clinic without their partners and (2) women refusing ANC attention in the absence of a partner. Theme 2 comprised extending invitations and had six subcategories: (1) word of mouth, (2) card invites, (3) woman's health passport book invites, (4) telephonic invites, (5) use of influential people, and (6) home visits. Theme 3 was information education and communication, such as health education forums and advertisements. Of all the strategies, an invitation card addressed to the male partner was most preferred by study participants. There are several strategies by which men may be involved in PMTCT. Healthcare workers should offer a pregnant woman all strategies available for MI for her to select the appropriate one. Further research and consultations with men should continue to achieve higher levels

    To evaluate use of combination neonatal prophylaxis (CNP) in infants at high risk for mother-to-child transmission (MTCT) of HIV in Europe and investigate whether CNP is more effective in preventing MTCT than single drug neonatal prophylaxis (SNP). Individual patient-data meta-analysis across eight observational studies. Factors associated with CNP receipt and with MTCT were explored by logistic regression using data from nonbreastfed infants, born between 1996 and 2010 and at high risk for MTCT. In 5285 mother-infant pairs, 1463 (27.7%) had no antenatal or intrapartum antiretroviral prophylaxis, 915 (17.3%) had only intrapartum prophylaxis and 2907 (55.0%) mothers had detectable delivery viral load despite receiving antenatal antiretroviral therapy. Any neonatal prophylaxis was administered to 4623 (87.5%) infants altogether; 1105 (23.9%) received CNP. Factors significantly associated with the receipt of CNP were later calendar birth year, no elective caesarean section, maternal CD4 cell count less than 200 cells/μl, maternal delivery viral load more than 1000 copies/ml, no antenatal antiretroviral therapy, receipt of intrapartum single-dose nevirapine and cohort. After adjustment, absence of neonatal prophylaxis was associated with higher risk of MTCT compared to neonatal prophylaxis [adjusted odds ratio (aOR) 2.29; 95% confidence interval (95% CI) 1.46-2.59; P use is increasing and associated with presence of MTCT risk factors. The finding of no observed difference in MTCT risk between one drug and CNP may reflect residual confounding or the fact that CNP may be effective only in a subgroup of infants rather than the whole population of high-risk infants.

    Full Text Available Background: Even though significant progress has been made in the roll-out and quality of the prevention of mother-to-child transmission of HIV (PMTCT services in South Africa, the quality of patient data recording remains a challenge. Objectives: To assess PMTCT data completeness and accuracy at primary healthcare level to district level in order to assist with the improvement of the PMTCT data recording. Methods: This is a retrospective record review study which involved collecting PMTCT data on indicators which was for the period of August 2009 to January 2010. We conducted baseline facility assessments which included 72 PMTCT sites in one health district, Nkangala. We assessed the data completeness and accuracy of the data values recorded on the seven PMTCT data elements. Results: Data were only complete for less than a quarter of the time for most of the antenatal indicators (0.5% – 44% and for the maternity indicators, data were only complete 11% of the time. Data inaccuracy was a result of recording of data values in the District Health Information System (DHIS which were not within 10% of the data values recorded in the case registers. The results show that data were missing from the case registers, monthly summary sheets and DHIS between 30% and 99% of the time and that data elements had values recorded in the DHIS which were > 10%. Conclusion: There is a need for ongoing training on data recording procedures at all levels. To maintain data quality, healthcare data must be appropriate, organised, timely, available, accurate and complete.

    The Zambian Defence Force (ZDF) is working to improve the quality of services to prevent mother-to-child transmission of HIV (PMTCT) at its health facilities. This study evaluates the impact of an intervention that included provider training, supportive supervision, detailed performance standards, repeated assessments of service quality, and task shifting of group education to lay workers. Four ZDF facilities implementing the intervention were matched with four comparison sites. Assessors visited the sites before and after the intervention and completed checklists while observing 387 antenatal care (ANC) consultations and 41 group education sessions. A checklist was used to observe facilities' infrastructure and support systems. Bivariate and multivariate analyses were conducted of findings on provider performance during consultations. Among 137 women observed during their initial ANC visit, 52% came during the first 20 weeks of pregnancy, but 19% waited until the 28th week or later. Overall scores for providers' PMTCT skills rose from 58% at baseline to 73% at endline (p=0.003) at intervention sites, but remained stable at 52% at comparison sites. Especially large gains were seen at intervention sites in family planning counseling (34% to 75%, p=0.026), HIV testing during return visits (13% to 48%, p=0.034), and HIV/AIDS management during visits that did not include an HIV test (1% to 34%, p=0.004). Overall scores for providers' ANC skills rose from 67% to 74% at intervention sites, but declined from 65% to 59% at comparison sites; neither change was significant in the multivariate analysis. Overall scores for group education rose from 87% to 91% at intervention sites and declined from 78% to 57% at comparison sites. The overall facility readiness score rose from 73% to 88% at intervention sites and from 75% to 82% at comparison sites. These findings are relevant to civilian as well as military health systems in Zambia because the two are closely coordinated

    Full Text Available Single-dose nevirapine (sd-NVP has been the main option for prevention of mother-to-child transmission (PMTCT of HIV-1 in low-resource settings. However, sd-NVP can induce the selection of HIV-1 resistant mutations in mothers and infants. In Mozambique, there are limited data regarding the profile of NVP resistance associated mutations (RAM in the context of PMTCT.To assess the prevalence and the factors associated with NVP RAM among children born to HIV-1 infected mothers enrolled in the PMTCT programme adopted in Mozambique.One hundred and fifty seven children aged 6 to 48 weeks were sequentially included (July 2011 to March 2012 at four centres in Maputo. Genotyping of RAM was performed in samples with HIV-1 RNA≥ 100 copies/μL (Viroseq. Sequencing was performed with ABI 3100 (Applied Biosystems. Logistic regression modelling was undertaken to identify the factors associated with NVP RAM.Seventy-nine children had their samples genotyped. Their median age was 7.0 (3-12 months and 92.4% received prophylaxis with sd-NVP at birth plus daily NVP. 35.4% of mothers received antiretrovirals (ARVs for PMTCT. ARV RAM were detected in 43 (54.4% of the children. 45.6% of these children had at least one NVP RAM. The most common mutations associated with NVP resistance were K103N (n = 16 and Y181C (n = 15. NVP RAM was significantly associated with mother exposure to PMTCT (crude odds ratio [OR] 30.3, 95% CI 4.93-186.34 and with mother's CD4 count < 350 cells/mm3 (crude OR 3.08, 95% CI 1.02-9.32. In the multivariable analysis the mother's exposure to PMTCT was the only variable significantly associated with NVP RAM (adjusted OR 48.65, 95% CI 9.33-253.66.We found a high prevalence of NVP RAM among children who were exposed to the drug regimen for PMTCT in Mozambique. The mothers' exposure to PMTCT significantly increased the risk of NVP RAM.

    The global scale-up of Prevention of mother-to-child transmission (PMTCT) services is credited for a 52% worldwide decline in new HIV infections among children between 2001 and 2012. However, the epidemic continues to challenge maternal and paediatric HIV control efforts in Sub Saharan Africa (SSA), with repercussions on other health services beyond those directly addressing HIV and AIDS. This systematised narrative review describes the effects of PMTCT programs on other health care services and the implications for improving health systems in SSA as reported in the existing articles and scientific literature. The following objectives framed our review:To describe the effects of PMTCT on health care services and systems in SSA and assess whether the PMTCT has strengthened or weakened health systems in SSATo describe the integration of PMTCT and its extent within broader programs and health systems. Articles published in English and French over the period 1st January 2007 (the year of publication of WHO/UNICEF guidelines on global scale-up of the PMTCT) to 31 November 2016 on PMTCT programs in SSA were sought through searches of electronic databases (Medline and Google Scholar). Articles describing the impact (positive and negative effects) of PMTCT on other health care services and those describing its integration in health systems in SSA were eligible for inclusion. We assessed 6223 potential papers, reviewed 225, and included 57. The majority of selected articles offered arguments for increased health services utilisation, notably of ante-natal care, and some evidence of beneficial synergies between PMTCT programs and other health services especially maternal health care, STI prevention and early childhood immunisation. Positive and negative impact of PMTCT on other health care services and health systems are suggested in thirty-two studies while twenty-five papers recommend more integration and synergies. However, the empirical evidence of impact of PMTCT

    Between 2011 and 2013, global and national guidelines for preventing mother-to-child transmission (PMTCT) of HIV shifted to recommend Option B+, the provision of lifelong antiretroviral treatment for all HIV-infected pregnant women. We aimed to analyse how Option B+ reached the policy agenda, and unpack the processes, actors and politics that explain its adoption, with a focus on examining UNICEF's contribution to these events. Analysis drew on published articles and other documentation, 30 key informants interviews with staff at UNICEF, partner organisations and government officials, and country case studies. Cameroon, India, South Africa and Zimbabwe were each visited for 5-8 days. Interview transcripts were analysed using Dedoose software, reviewed several times and then coded thematically. A national policy initiative in Malawi in 2011, in which the country adopted Option B+, rather than existing WHO recommended regimens, irrevocably placed the policy on the global agenda. UNICEF and other organisations recognised the policy's potential impact and strategically crafted arguments to support it, framing these around operational considerations, cost-effectiveness and values. As 'policy entrepreneurs', these organisations vigorously promoted the policy through a variety of channels and means, overcoming concerted opposition. WHO, on the basis of scanty evidence, released a series of documents towards the policy's endorsement, paving the way for its widespread adoption. National-level policy transformation was rapid and definitive, distinct from previous incremental policy processes. Many organisations, including UNICEF, facilitated these changes in country, acting individually, or in concert. The adoption of the Option B+ policy marked a departure from established processes for PMTCT policy formulation which had been led by WHO with the support of technical experts, and in which recommendations were developed following shifts in evidence. Rather, changes were

    Option B+ for the prevention of mother-to-child transmission (PMTCT) of HIV (i.e., lifelong antiretroviral treatment for all pregnant and breastfeeding mothers living with HIV) was initiated in Tanzania in 2013. While there is evidence that this policy has benefits for the health of the mother and the child, Option B+ may also increase the workload for health care providers in resource-constrained settings, possibly leading to job dissatisfaction and unwanted workforce turnover. From March to April 2014, a questionnaire asking about job satisfaction and turnover intentions was administered to all nurses at 36 public-sector health facilities offering antenatal and PMTCT services in Dar es Salaam, Tanzania. Multivariable logistic regression models were used to identify factors associated with job dissatisfaction and intention to quit one's job. Slightly over half (54%, 114/213) of the providers were dissatisfied with their current job, and 35% (74/213) intended to leave their job. Most of the providers were dissatisfied with low salaries and high workload, but satisfied with workplace harmony and being able to follow their moral values. The odds of reporting to be globally dissatisfied with one's job were high if the provider was dissatisfied with salary (adjusted odds ratio (aOR) 5.6, 95% CI 1.2-26.8), availability of protective gear (aOR 4.0, 95% CI 1.5-10.6), job description (aOR 4.3, 95% CI 1.2-14.7), and working hours (aOR 3.2, 95% CI 1.3-7.6). Perceiving clients to prefer PMTCT Option B+ reduced job dissatisfaction (aOR 0.2, 95% CI 0.1-0.8). The following factors were associated with providers' intention to leave their current job: job stability dissatisfaction (aOR 3.7, 95% CI 1.3-10.5), not being recognized by one's superior (aOR 3.6, 95% CI 1.7-7.6), and poor feedback on the overall unit performance (aOR 2.7, 95% CI 1.3-5.8). Job dissatisfaction and turnover intentions are comparatively high among nurses in Dar es Salaam's public-sector maternal care

    Implementation research (IR) facilitates health systems strengthening and optimal patient outcomes by generating evidence for scale-up of efficacious strategies in context. Thus, difficulties in generating IR evidence, particularly in limited-resource settings with wide disease prevention and treatment gaps, need to be anticipated and addressed. Nigeria is a priority country for the prevention of mother-to-child transmission of HIV (PMTCT). This paper analyses the experiences of four PMTCT IR studies in Nigeria, and proffers solutions to major challenges encountered during implementation. Multicentre PMTCT IR studies conducted in Nigeria during the Global Plan's assessment period (2011 to 2015) were included. Four studies were identified, namely The Baby Shower Trial, Optimizing PMTCT, MoMent and Lafiyan Jikin Mata. Major common challenges encountered were categorised as 'External' (beyond the control of study teams) and 'Internal' (amenable to rectification by study teams). External challenges included healthcare worker strikes and turnover, acts and threats of ethnic and political violence and terrorism, and multiplicity of required local ethical reviews. Internal challenges included limited research capacity among study staff, research staff turnover and travel restrictions hindering study site visits. Deliberate research capacity-building was provided to study staff through multiple opportunities before and during study implementation. Post-study employment opportunities and pathways for further research career-building are suggested as incentives for study staff retention. Engagement of study community-resident personnel minimised research staff turnover in violence-prone areas. The IR environment in Nigeria is extremely diverse and challenging, yet, with local experience and anticipatory planning, innovative solutions can be implemented to modulate internal challenges. Issues still remain with healthcare worker strikes and often unpredictable insecurity

    Community-based mobile phone programs can complement gaps in clinical services for prevention of mother-to-child transmission (PMTCT) of HIV in areas with poor infrastructure and personnel shortages. However, community and health worker perceptions on optimal mobile phone communication for PMTCT are underexplored. This study examined what specific content and forms of mobile communication are acceptable to support PMTCT. Qualitative methods using focus groups and in-depth interviews were conducted in two district hospitals in Nyanza Province, Kenya. A total of 45 participants were purposefully selected, including HIV-positive women enrolled in PMTCT, their male partners, community health workers, and nurses. Semi-structured discussion guides were used to elicit participants' current mobile phone uses for PMTCT and their perceived benefits and challenges. We also examined participants' views on platform design and gender-tailored short message service (SMS) messages designed to improve PMTCT communication and male involvement. Most participants had access to a mobile phone and prior experience receiving and sending SMS, although phone sharing was common among couples. Mobile phones were used for several health-related purposes, primarily as voice calls rather than texts. The perceived benefits of mobile phones for PMTCT included linking with health workers, protecting confidentiality, and receiving information and reminders. Men and women considered the gender-tailored SMS as a catalyst for improving PMTCT male involvement and couples' communication. However, informative messaging relayed safely to the intended recipient was critical. In addition, health workers emphasized the continual need for in-person counseling coupled with, rather than replaced by, mobile phone reinforcement. For all participants, integrated and neutral text messaging provided antenatally and postnatally was most preferred, although not all topics or text formats were equally acceptable. Given

    The objective of the prevention of Mother-to-Child Transmission (pMTCT) cascade analysis tool is to provide frontline health managers at the facility level with the means to rapidly, independently and quantitatively track patient flows through the pMTCT cascade, and readily identify priority areas for clinic-level improvement interventions. Over a period of six months, five experienced maternal-child health managers and researchers iteratively adapted and tested this systems analysis tool for pMTCT services. They prioritized components of the pMTCT cascade for inclusion, disseminated multiple versions to 27 health managers and piloted it in five facilities. Process mapping techniques were used to chart PMTCT cascade steps in these five facilities, to document antenatal care attendance, HIV testing and counseling, provision of prophylactic anti-retrovirals, safe delivery, safe infant feeding, infant follow-up including HIV testing, and family planning, in order to obtain site-specific knowledge of service delivery. Seven pMTCT cascade steps were included in the Excel-based final tool. Prevalence calculations were incorporated as sub-headings under relevant steps. Cells not requiring data inputs were locked, wording was simplified and stepwise drop-offs and maximization functions were included at key steps along the cascade. While the drop off function allows health workers to rapidly assess how many patients were lost at each step, the maximization function details the additional people served if only one step improves to 100% capacity while others stay constant. Our experience suggests that adaptation of a cascade analysis tool for facility-level pMTCT services is feasible and appropriate as a starting point for discussions of where to implement improvement strategies. The resulting tool facilitates the engagement of frontline health workers and managers who fill out, interpret, apply the tool, and then follow up with quality improvement activities. Research on

    Websites that address national public health issues provide an important mechanism to improve health education and services in resource limited countries. This article describes the development, promotion and initial evaluation of a national website to increase access to information and resources about prevention of mother-to-child transmission of HIV (PMTCT) among healthcare workers and PMTCT stakeholders in Tanzania. A participatory approach, involving the Tanzania Ministry of Health and Social Welfare (MOHSW) and key PMTCT stakeholders, was used to develop and manage the online PMTCT National Resource Center (NRC), http://pmtct.or.tz/ . The website was created with a content management system software system that does not require advanced computer skills and facilitates content updates and site management. The PMTCT NRC hosts related regularly updated PMTCT-related news, resources and publications. Website implementation, access and performance were evaluated over two years using Google Analytics data about visits, page views, downloads, bounce rates and location of visitors, supplemented by anecdotal feedback. Following its launch in July 2013, the PMTCT NRC website received a total of 28,400 visits, with 66,463 page views, over 2 years; 30 % of visits were from returning visitors. During year 1, visits increased by 80 % from the first to second 6 month period and then declined slightly (9-11 %) but remained stable in Year 2. Monthly visits spiked by about 70 % during October 2013 and January 2014 in response to the release and promotion of revised national PMTCT guidelines and training manuals. The majority of visitors came from primarily urban areas in Tanzania (50 %) and from other African countries (16 %). By year 2, over one-third of visitors used mobile devices to access the site. The successfully implemented PMTCT NRC website provides centralized, easily accessed information designed to address the needs of clinicians, educators and program partners in

    Despite expanded programs for prevention of mother-to-child HIV transmission (PMTCT), HIV-infected infants may not be diagnosed until they are ill. Comparing HIV prevalence and outcomes in infants diagnosed in PMTCT programs to those in hospital settings may improve pediatric HIV diagnosis strategies. HIV-exposed infants turnaround time for tests were compared between PMTCT programs and hospital sites. Among the enrolled cohort, baseline characteristics, survival, and timing of antiretroviral therapy (ART) initiation were compared between infants diagnosed in PMTCT programs versus hospital. Among 1,923 HIV-exposed infants, HIV prevalence was higher among infants tested in hospital than PMTCT early infant diagnosis (EID) sites (41% vs. 11%, p 3 times as likely to die (HR = 3.1, 95% CI = 1.3-7.6). Among HIV-exposed infants, hospital-based testing was more likely to detect an HIV-infected infant than PMTCT testing. Because young symptomatic infants diagnosed with HIV during hospitalization have very high mortality, every effort should be made to diagnose HIV infections before symptom onset. Systems to expedite turnaround time at PMTCT EID sites and to routinize inpatient pediatric HIV testing are necessary to improve pediatric HIV outcomes.

    To characterize pregnant patients' knowledge, attitudes and preferences regarding antenatal HIV testing for themselves and their sexual partners. Observational, mixed methods study of HIV-negative pregnant women from a university-based urban clinic. Participants completed an anonymous survey about HIV testing for themselves and their partners. Descriptive statistics, bivariable analyses, multivariable logistic regression and qualitative thematic analysis were utilized. One hundred and forty-two patients (mean age 28.6±5.5 years) participated. A majority (57.7%) were married or partnered, and 92.9% reported having at least one current sexual partner. Although a majority (62.8%) reported their partner had a prior HIV test, and 93.0% of these women were aware of test results, only 20.7% reported partner testing had occurred in the past 6 months. Women who had a prior HIV test, who were older or who were non-white were more likely to be aware of their partner's HIV status. A majority (66.9%) of women desired knowledge of their partner's current status and 76.0% believed their partners would like to know his HIV status; in addition, 74% were interested in receiving partner testing at the site of prenatal care. Qualitative analysis demonstrated that health concerns and believing HIV knowledge is important to the relationship were motivators for desiring partner testing. In this urban community, a majority of pregnant women do not know HIV test results of their sexual partner during the current pregnancy. Women desired to know their partner's HIV status and were receptive to partner testing at the site of prenatal care or other locations. Partner testing may be a critical step toward elimination of seroconversion during pregnancy and maternal-to-child HIV transmission.

    To determine mother-to-child transmission (MTCT) rate and associated risk factors of human immune-deficiency virus (HIV) among HIV-infected pregnant women with term premature rupture of membranes (PROM) in comparison with those without PROM at term. All optimally managed HIV-positive pregnant women of Nnamdi Azikiwe University Teaching Hospital, on highly active anti-retroviral therapy (HAART) who had PROM at term were enrolled. Maternal HIV-1 viral load was not assessed. Follow up was for a minimum of 18 months for evidence of HIV infection. Of the 121 women with PROM at term, 46 (38.0%) were HIV sero-positive, 22/46 (47.8%) of which had their babies followed up till 18 months. The mean latency period was 10.5 ± 5.3 h in PROM group. Apart from duration of PROM (OR = 0.01; 95%CI = 0.00-0.13; p  0.05). Of the 22 (47.8%) babies followed-up in the PROM group and 13 in non-PROM group, none tested positive to HIV, given an MTCT rate of 0%. MTCT rate was 0% following term PROM and in women without PROM. Since maternal HIV-1 viral load was not assessed, we need to be critical while interpreting the findings.

    Full Text Available Objectives: International guidelines on infant feeding for HIV-positive mothers promote Exclusive Replacement Feeding (ERF (infant formula or animal milk or exclusive breastfeeding (with no supplements of any kind. A mixed feeding pattern, where breastfeeding is combined with other milks, liquid foods or solids, has been shown to increase the risk of transmission of HIV and is strongly discouraged. However, little is known about the ability of women to adhere to recommended feeding strategies to prevent mother-to-child transmission (MTCT of HIV from breast milk. The objective of this study was to assess the individual and community-level factors that affect perspectives, attitudes and practices of HIV-positive mothers on MTCT and infant feeding in sub-Saharan Africa as documented in peer-reviewed and grey literature. Methods: This work is based on an extensive review of peer-reviewed articles and grey literature from the period 2000-2012. The literature search was carried out using electronic databases like, Medline Ovid, Google scholar, Pubmed and EBSCOhost. Both quantitative and qualitative studies written in English language on HIV and infant feeding with particular emphasis on sub-Saharan Africa were included. Results: The review found low adherence to the chosen infant feeding method by HIV-positive mothers. The following factors emerged as influencing infant feeding decisions: cultural and social norms; economic conditions; inadequate counselling; and mother’s level of education. Conclusions and Public Health Implications: Unless local beliefs and customs surrounding infant feeding is understood by policy makers and program implementers, Prevention of Mother-to-Child Transmission (PMTCT programs will only be partially successful in influencing feeding practices of HIV-positive women. Hence programs should provide affordable, acceptable, feasible, safe and sustainable feeding recommendations that do not erode strong cultural practices

    Retention in care remains an important issue for prevention of mother-to-child transmission (PMTCT) programs according to WHO guidelines, formerly called the "Option B+" approach. The objective of this study was to examine how poverty, gender, and health system factors interact to influence women's participation in PMTCT services. We used qualitative research, literature, and hypothesized variable connections to diagram causes and effects in causal loop models. We found that many factors, including antiretroviral therapy (ART) use, service design and quality, stigma, disclosure, spouse/partner influence, decision-making autonomy, and knowledge about PMTCT, influence psychosocial health, which in turn affects women's participation in PMTCT services. Thus, interventions to improve psychosocial health need to address many factors to be successful. We also found that the design of PMTCT services, a modifiable factor, is important because it affects several other factors. We identified 66 feedback loops that may contribute to policy resistance-that is, a policy's failure to have its intended effect. Our findings point to the need for a multipronged intervention to encourage women's continued participation in PMTCT services and for longitudinal research to quantify and test our causal loop model.

    In pregnancy early interventions are recommended for prevention of mother-to-child-transmission (PMTCT) of HIV. We examined whether pregnant women who live with HIV in Europe and are migrants encounter barriers in accessing HIV testing and care. Four cohorts within the European Pregnancy and Paediatric HIV Cohort Collaboration provided data for pooled analysis of 11 795 pregnant women who delivered in 2002-12 across ten European countries. We defined a migrant as a woman delivering in a country different from her country of birth and grouped the countries into seven world regions. We compared three suboptimal PMTCT interventions (HIV diagnosis in late pregnancy in women undiagnosed at conception, late anti-retroviral therapy (ART) start in women diagnosed but untreated at conception and detectable viral load (VL) at delivery in women on antenatal ART) in native and migrant women using multivariable logistic regression models. Data included 9421 (79.9%) migrant women, mainly from sub-Saharan Africa (SSA); 4134 migrant women were diagnosed in the current pregnancy, often (48.6%) presenting with CD4 count <350 cells/µl. Being a migrant was associated with HIV diagnosis in late pregnancy [OR for SSA vs. native women, 2.12 (95% CI 1.67, 2.69)] but not with late ART start if diagnosed but not on ART at conception, or with detectable VL at delivery once on ART. Migrant women were more likely to be diagnosed in late pregnancy but once on ART virological response was good. Good access to antenatal care enables the implementation of PMTCT protocols and optimises both maternal and children health outcomes generally. © The Author 2017.

    Mother-to-Child Transmission (MTCT) has been identified as the greatest means of HIV infection among children. Adherence to antiretroviral drugs is necessary to prevent drug resistance and MTCT of HIV among HIV positive women. However, there is a gap in clients' knowledge, attitudes and perceptions of antiretroviral therapy (ART) and Prevention of Mother-To-Child Transmission (PMTCT) which influence their decision to adhere to ART. The study was a descriptive cross-sectional employing both qualitative and quantitative methods. The study involved 229 HIV positive women in reproductive age (18 - 49 years) and had been on ART for at least six months. Fourteen health workers were also included in the qualitative study. Respondents were selected from three ART centers in the Kumasi Metropolis through systematic random sampling from August to November 2011. HIV positive women who had consistently missed two or more ART appointments within the previous two months were classified as defaulters. Data was analyzed with SPSS 19 and STATA 11. Logistic regression was run to assess the odds ratios at 95% confidence level. The ART defaulter rate was 27% and clients had good knowledge about ART and PMTCT. More than 90% of the HIV positive women had inadequate knowledge about ART and PMTCT and these women were more likely to default ART (OR = 3.5; 95% CI = 1.89, 6.21). The educational background of HIV positive women did not have significant influence on their knowledge of ART and PMTCT. Mothers, knowledge and understanding of ART and PMTCT could influence their adherence to ART. Educational interventions which target the understanding of both the literate and illiterate women in society are necessary to develop positive behaviors and enhance adherence to ART.

    Health utility (HU) is essential to understanding the effects of HIV infection as a chronic disease. No HU data on pregnant women living with human immunodeficiency virus (HIV) in Yunnan Province are available. This study aims to construct a database on HU and explore factors associated with HU by pregnant women living with HIV/acquired immunodeficiency syndrome (AIDS) who were enrolled in the Prevention of mother-to-child transmission of HIV (PMTCT) programs in Yunnan Province. A cross-sectional study was conducted in Yunnan Province on pregnant women living with HIV who were selected by convenience sampling. Sociodemographic, HIV-related, social support, and HU data were collected through face-to-face interviews. The European quality of life five-dimensional three-level (EQ-5D-3L) questionnaire and the social support rate scale (SSRS) were applied. One hundred and one pregnant women (mean age of 30.4 ± 5.1 years) participated in the survey. The mean EQ-5D index score and the EQ visual analogue scale (EQ-VAS) score of participants were 0.77 (95% confidence interval [CI] 0.74-0.79) and 75.77 (95% CI 75.00-80.00), respectively. The effect of social support on HU was maintained significant difference even after adjusting for such factors as education level, household income per year, and HIV disclosure, demonstrating a significant difference within EQ-5D index scores and EQ-VAS scores. Pregnant women living with HIV/AIDS who were enrolled in PMTCT programs reported the same level of HU as other patients living with HIV/AIDS. Integrating measurements of HU by using the EQ-5D-3L questionnaire could be helpful for economic evaluation of the PMTCT program. This study also suggests a potential benefit of appropriate social support. Copyright © 2018. Published by Elsevier Inc.

    Despite the success of Prevention of Mother-to-Child Transmission of HIV (PMTCT) programmes, low uptake of services and poor retention pose a formidable challenge to achieving the elimination of vertical HIV transmission in low- and middle-income countries. This systematic review summarises interventions that demonstrate statistically significant improvements in service uptake and retention of HIV-positive pregnant and breastfeeding women and their infants along the PMTCT cascade. Databases were systematically searched for peer-reviewed studies. Outcomes of interest included uptake of services, such as antiretroviral therapy (ART) such as initiation, early infant diagnostic testing, and retention of HIV-positive pregnant and breastfeeding women and their infants. Interventions that led to statistically significant outcomes were included and mapped to the PMTCT cascade. An eight-item assessment tool assessed study rigour. CRD42017063816. Of 686 citations reviewed, 11 articles met inclusion criteria. Ten studies detailed maternal outcomes and seven studies detailed infant outcomes in PMTCT programmes. Interventions to increase access to antenatal care (ANC) and ART services (n = 4) and those using lay cadres (n = 3) were most common. Other interventions included quality improvement (n = 2), mHealth (n = 1), and counselling (n = 1). One study described interventions in an Option B+ programme. Limitations included lack of HIV testing and counselling and viral load monitoring outcomes, small sample size, geographical location, and non-randomized assignment and selection of participants. Interventions including ANC/ART integration, family-centred approaches, and the use of lay healthcare providers are demonstrably effective in increasing service uptake and retention of HIV-positive mothers and their infants in PMTCT programmes. Future studies should include control groups and assess whether interventions developed in the context of earlier 'Options' are

    HIV testing is an effective intervention that is used for reducing perinatal HIV transmission. Centers for Disease Control and Prevention recommends a second HIV test during the third trimester of pregnancy for women in settings with an elevated HIV incidence (≥17 cases per 100,000 person-years). We conducted a retrospective cohort study at a single hospital in Baltimore, Maryland, to determine whether a second HIV test was done and to compare HIV retesting with mandated syphilis retesting. Of women who delivered at this hospital, 98.8% received prenatal care. Descriptive, bivariate, and multivariable analyses were performed. Among 1632 women, mean age was 27.6 years (standard deviation: 6.3), 59.6% were black, and 55.5% were single. HIV retesting was done in 28.4% of women, which was significantly less often compared with the state-mandated syphilis retesting (78.7%, p HIV retest were 15 times higher among women who received prenatal care at a teaching clinic [adjusted odds ratio (aOR): 15.58; 95% confidence interval (CI): 11.12-21.81], and they were lower among women with private insurance (aOR: 0.54, 95% CI: 0.34-0.86). The odds of having a syphilis retest were twice as high among women who received prenatal care at a faculty practice (aOR: 2.17; 95% CI: 1.53-3.09), and they were lower among women with private insurance (aOR: 0.61, 95% CI: 0.43-0.88). Emphasizing an "opt-out" HIV retesting approach through state laws may minimize risk perception, and this is one strategy that can be considered in areas of high HIV incidence to reach the goal of eliminating perinatal HIV transmission in the United States.

    Objective We estimated HIV-free infant survival and mother-to-child HIV transmission (MTCT) rates in Zimbabwe, some of the first community-based estimates from a UNAIDS priority country. Methods In 2012 we surveyed mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. Enrolled infants were born 9–18 months before the survey. We collected questionnaires, blood samples for HIV testing, and verbal autopsies for deceased mothers/infants. Estimates were assessed among i) all HIV-exposed infants, as part of an impact evaluation of Option A of the 2010 WHO guidelines (rolled out in Zimbabwe in 2011), and ii) the subgroup of infants unexposed to Option A. We compared province-level MTCT rates measured among women in the community with MTCT rates measured using program monitoring data from facilities serving those communities. Findings Among 8568 women with known HIV serostatus, 1107 (12.9%) were HIV-infected. Among all HIV-exposed infants, HIV-free infant survival was 90.9% (95% confidence interval (CI): 88.7–92.7) and MTCT was 8.8% (95% CI: 6.9–11.1). Sixty-six percent of HIV-exposed infants were still breastfeeding. Among the 762 infants born before Option A was implemented, 90.5% (95% CI: 88.1–92.5) were alive and HIV-uninfected at 9–18 months of age, and 9.1% (95%CI: 7.1–11.7) were HIV-infected. In four provinces, the community-based MTCT rate was higher than the facility-based MTCT rate. In Harare, the community and facility-based rates were 6.0% and 9.1%, respectively. Conclusion By 2012 Zimbabwe had made substantial progress towards the elimination of MTCT. Our HIV-free infant survival and MTCT estimates capture HIV transmissions during pregnancy, delivery and breastfeeding regardless of whether or not mothers accessed health services. These estimates also provide a baseline against which to measure the impact of Option A guidelines (and subsequently Option B+). PMID:26248197

    To demonstrate the effectiveness of prevention of mother-to-child HIV, syphilis, and hepatitis B transmission among pregnant women in Dehong prefecture, Yunnan province, China from 2011 to 2013. Data were collected mainly from the continuous HIV surveillance system and prevention of mother-to-child transmission (PMTCT) reporting system of Dehong prefecture, and supplemented by annual reported data on HIV, syphilis, and hepatitis B PMTCT to know the general demographic characteristics, HIV testing and counseling service, PMTCT service, and other medical services. Data were presented as absolute numbers and proportions. From 2011 to 2013, the number of pregnant women participating in HIV, syphilis, and hepatitis B testing in Dehong prefecture increased and the HIV testing rates were 99.2% (18 694/18 854), 99.9% (22 047/22 060) and 99.9% (21 751/21 756), the syphilis testing rates were 56.0% (10 550/18 854), 99.6% (21 980/22 060) and 99.9% (21 751/21 756), and the hepatitis B testing rates were 60.2% (11 358/18 854), 99.6% (21 974/22 060) and 99.9% (21 751/21 756). From 2011 to 2013, the HIV positive rates were 0.87% (327/37 787),0.82% (319/38 817) and 0.85% (315/37 261), the syphilis positive rates were 0.05% (10/18 520),0.12% (43/36 817) and 0.11% (40/35 888), the hepatitis B positive rates were 2.46% (456/18 520), 2.23% (794/35 547) and 2.14% (739/34 468), respectively. The rates of HIV-positive pregnant women giving birth in hospitals were 99.2% (128/129), 100.0% (141/141) and 100.0% (141/141). From 2011 to 2013, the proportions of HIV-positive pregnant women receiving antiretroviral therapy were 99.2% (128/129), 99.3% (140/141) and 99.3% (140/141), respectively. And the treatment rate of syphilis-positive pregnant women were 71% (5/7), 89% (16/18) and 97% (32/33). The rates of hepatitis B immunoglobulin injection among new-borns of hepatitis B-positive pregnant women were 92.9% (263/283), 99.7% (612/614) and 99.4% (629/633).

    Full Text Available The prevention of mother-to-child transmission (PMTCT programme in the central region of Ethekweni Metro, KwaZulu-Natal (Durban central area, was investigated. Data for all HIV-exposed infants from eight private paediatric practices seen between January 2004 and June 2005 were reviewed retrospectively. One hundred and one black African infants were born to 100 HIV-positive women of average age 30 years. Median viral loads and CD4 counts were 11 391 copies/ml and 426 cells/μl, respectively. Eighty-six women received HAART and 5 had no prophylaxis. Of the 92 infants tested, 2 were HIV positive, giving a transmission rate of 2.2%. Both their mothers had received suboptimal prophylaxis, and if they are excluded, the transmission rate falls to less than 1%, a rate consistent with those in the developed world.

    To synthesize and evaluate the impact of implementing post-2010 World Health Organization (WHO) prevention of mother-to-child transmission (PMTCT) guidelines on attainment of PMTCT targets. Retrospective and prospective cohort study designs that utilized routinely collected data with a focus on provision and utilization of the cascade of PMTCT services were included. The outcomes included the proportion of pregnant women who were tested during their antenatal clinic (ANC) visits; mother-to-child transmission (MTCT) rate; adherence; retention rate; and loss to follow-up (LTFU). Of the 1210 references screened, 45 met the inclusion criteria. The studies originated from 14 countries in sub-Saharan Africa. The highest number of studies originated from Malawi (10) followed by Nigeria and South Africa with 7 studies each. More than half of the studies were on option A while the majority of option B+ studies were conducted in Malawi. These studies indicated a high uptake of human immunodeficiency virus (HIV) testing ranging from 75% in Nigeria to over 96% in Zimbabwe and South Africa. High proportions of CD4 count testing were reported in studies only from South Africa despite that in most of the countries CD4 testing was a prerequisite to access treatment. MTCT rate ranged from 1.1% to 15.1% and it was higher in studies where data were collected in the early days of the WHO 2010 PMTCT guidelines. During the postpartum period, adherence and retention rate decreased, and LTFU increased for both HIV-positive mothers and exposed infants. Irrespective of which option was followed, uptake of antenatal HIV testing was high but there was a large drop off along later points in the PMTCT cascade. More research is needed on how to improve later components of the PMTCT cascade, especially of option B+ which is now the norm throughout sub-Saharan Africa.

    Full Text Available Optimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal disease.A total of 311 HIV-infected pregnant women were enrolled in Malawi in an observational study and received a nevirapine-based regimen from week 25 of gestation until 6 months after delivery (end of breastfeeding period if their CD4+ count was > 350/mm(3 at baseline (n = 147, or indefinitely if they met the criteria for treatment (n. 164. Mother/child pairs were followed until 2 years after delivery. The Kaplan-Meier method was used to estimate HIV transmission, maternal disease progression, and survival at 24 months. The rate of HIV infant infection was 3.2% [95% confidence intervals (CI 1.0-5.4]. Six of the 8 transmissions occurred among mothers with baseline CD4+ count > 350/mm(3. HIV-free survival of children was 85.8% (95% CI 81.4-90.1. Children born to mothers with baseline CD4+ count < 350/mm(3 were at increased risk of death (hazard ratio 2.6, 95% CI 1.1-6.1. Among women who had stopped treatment the risk of progression to CD4+ count < 350/mm(3 was 20.6% (95% CI 9.2-31.9 by 18 months of drug discontinuation.HIV transmission in this cohort was rare however, it occurred in a significative proportion among women with high CD4+ counts. Strategies to improve treatment adherence should be implemented to further reduce HIV transmission. Mortality in the uninfected exposed children was the major determinant of HIV-free survival and was associated to maternal disease stage. Given the considerable proportion of women reaching the criteria for treatment within 18 months of drug discontinuation, life-long ART administration to HIV-infected women should be considered.

    Children living with HIV worldwide majority are infected through mother to child transmission of HIV (MTCT) acquired during pregnancy. Knowledge, attitude and behavioral changes are pivot tools towards success of any interventions. To determine the effectiveness of counseling on HIV done in primary health facilities (PHF), level of knowledge gained and attitude changes towards PMTCT. A cross sectional study assessing pregnant women's knowledge and their attitude towards PMTCT was conducted in Temeke district from October 2010 to Jan 2011 using a structured questionnaire. A total of 383 antenatal attendees were referred to Temeke district for management after counselled and tested for HIV in PHFs. Majority (86.9%) had primary education and good knowledge on MTCT. Correct timing of ARVs prophylaxis (15.7%) as preventive measures for MTCT was poor. Education and employment were associated with good knowledge on MTCT of HIV. Women had positive attitudes towards HIV counseling and testing, but stigma was a barrier to disclosure of one's serostatus. There is knowledge gap in routine PMTCT counseling among antenatal attendees in our PHFs. Effective counseling on PMTCT in the PHFs will bridge the identified knowledge gap and help in reduction of pediatric HIV.

    To assess the uptake of WHO-recommended PMTCT procedures in Ethiopia's health services. Prospective observational study of HIV-positive pregnant mothers and their newborns attending PMTCT services at seven health centres in Addis Ababa. Women were recruited during antenatal care and followed up with their newborns at delivery, Day 6 and Week 6 post-partum. Retention to PMCTC procedures, self-reported antiretroviral treatment (ART) adherence and HIV infant outcome were assessed. Turnaround times of HIV early infant diagnosis (EID) procedures were extracted from health registers. Of 494 women enrolled, 4.9% did not complete PMTCT procedures due to active denial or loss to follow-up. HIV was first diagnosed in 223 (45.1%) and ART initiated in 321 (65.0%) women during pregnancy. ART was initiated in a median of 1.3 weeks (IQR 0-4.3) after HIV diagnosis. Poor self-reported treatment adherence was higher post-partum than during pregnancy (12.5% vs. 7.0%, P = 0.002) and significantly associated with divorced/separated marital status (RR 2.2, 95% CI 1.3-3.8), low family income (RR 2.1, 95% CI 1.1-4.1), low CD4 count (RR 1.7, 95% CI 1.0-3.0) and ART initiation during delivery (RR 2.5, 95% CI 1.1-5.6). Of 435 infants born alive, 98.6% received nevirapine prophylaxis. The mother-to-child HIV transmission rate was 0.7% after a median of 6.7 weeks (IQR 6.4-10.4), but EID results were received for only 46.6% within 3 months of birth. High retention in PMTCT services, triple maternal ART and high infant nevirapine prophylaxis coverage were associated with low mother-to-child HIV transmission. Declining post-partum ART adherence and challenges of EID linkage require attention. © 2017 The Authors. Tropical Medicine & International Health Published by John Wiley & Sons Ltd.

    Full Text Available As the world is making progress towards elimination of mother-to-child transmission of HIV, poor coverage of PMTCT services in Nigeria remains a major challenge. In order to address this, scale-up was planned with activities organized into 3 phases. This paper describes the process undertaken in eight high burden Nigerian states to rapidly close PMTCT coverage gaps at facility and population levels between February 2013 and March 2014.Activities were grouped into three phases-pre-assessment phase (engagement of a wide range of stakeholders, assessment (rapid health facility assessment, a cross sectional survey using mixed methods conducted in the various states between Feb and May 2013 and impact modelling, and post-assessment (drawing up costed state operational plans to achieve eMTCT by 2015, data-driven smart scale-up.Over a period of 10 months starting June 2013, 2044 facilities were supported to begin provision of PMTCT services. This increased facility coverage from 8% to 50%. A 246% increase was also recorded in the number of pregnant women and their families who have access to HIV testing and counselling in the context of PMTCT. Similarly, access to antiretrovirals for PMTCT has witnessed a 152% increase in these eight states between October 2013 and October 2014.A data-driven and participatory approach can be used to rapidly scale-up PMTCT services at community and facility levels in this region. These results present us with hope for real progress in Nigeria. We are confident that the efforts described here will contribute significantly to eliminating new pediatric HIV infection in Nigeria.

    Full Text Available Abstract Objectives to evaluate mother-to-child transmission (MTCT rates and related factors in HIV-infected pregnant women from a tertiary hospital between 2000 and 2009. Subjects and method cohort of 452 HIV-infected pregnant women and their newborns. Data was collected from recorded files and undiagnosed children were enrolled for investigation. Statistical analysis: qui-square test, Fisher exact test, Student t test, Mann-Whitney test, ANOVA, risk ratio and confidence intervals. Results MTCT occurred in 3.74%. The study population displayed a mean age of 27 years; 86.5% were found to have acquired HIV through sexual contact; 55% were aware of the diagnosis prior to the pregnancy; 62% were not using HAART. Mean CD4 cell-count was 474 cells/ml and 70.3% had undetectable viral loads in the third trimester. HAART included nevirapine in 35% of cases and protease inhibitors in 55%; Zidovudine monotherapy was used in 7.3%. Mean gestational age at delivery was 37.2 weeks and in 92% by caesarian section; 97.2% received intravenous zidovudine. Use of AZT to newborn occurred in 100% of them. Factors identified as associated to MTCT were: low CD4 cell counts, elevated viral loads, maternal AIDS, shorter periods receiving HAART, other conditions (anemia, IUGR (intra uterine growth restriction, oligohydramnium, coinfecctions (CMV and toxoplasmosis and the occurrence of labor. Use of HAART for longer periods, caesarian and oral zidovudine for the newborns were associated with a decreased risk. Poor adhesion to treatment was present in 13 of the 15 cases of transmission; in 7, coinfecctions were diagnosed (CMV and toxoplasmosis. Conclusion Use of HAART and caesarian delivery are protective factors for mother-to-child transmission of HIV. Maternal coinfecctions and other conditions were risk factors for MTCT.

    Objective To examine the acceptability and feasibility of mobile health (mHealth)/short message service (SMS) and community-based directly observed antiretroviral therapy (cDOT) as interventions to improve antiretroviral therapy (ART) adherence for preventing mother-to-child human immunodeficiency virus (HIV) transmission (PMTCT). Design and methods A mixed-method approach was used. Two qualitative focus group discussions with HIV-infected pregnant women (n=20) examined the acceptability and feasibility of two ART adherence interventions for PMTCT: 1) SMS text messaging and 2) patient-nominated cDOT supporters. Additionally, 109 HIV-infected, pregnant South African women (18–30 years old) receiving PMTCT services under single-tablet antiretroviral therapy regimen during pregnancy and breastfeeding and continuing for life (“Option B+”) were interviewed about mobile phone access, SMS use, and potential treatment supporters. Setting A community primary care clinic in Cape Town, South Africa. Participants HIV-infected pregnant women. Main outcomes Acceptability and feasibility of mHealth and cDOT interventions. Results Among the 109 women interviewed, individual mobile phone access and SMS use were high (>90%), and 88.1% of women were interested in receiving SMS ART adherence support messages such as reminders, motivation, and medication updates. Nearly all women (95%) identified at least one person close to them to whom they had disclosed their HIV status and would nominate as a cDOT supporter. Focus group discussions revealed that cDOT supporters and adherence text messages were valued, but some concerns regarding supporter time availability and risk of unintended HIV status disclosure were expressed. Conclusion mHealth and/or cDOT supporter as interventions to improve ART adherence are feasible in this setting. However, safe HIV status disclosure to treatment supporters and confidentiality of text messaging content about HIV and ART were deemed crucial. PMID

We explored reasons for LTFU during prevention of mother-to-child transmission (PMTCT from a client perspective in eastern Uganda, where antiretroviral therapy (ART awareness is presumably high.Methods: Seven key informant interviews and 20 in-depth interviews, including both clients who had been retained under PMTCT care and those LTFU during PMTCT were held. Ten focus-group discussions involving a total of 112 participants were also conducted with caretakers/relatives of the PMTCT clients. Content analysis was performed to identify recurrent themes.Results: Our findings indicate that LTFU during PMTCT in eastern Uganda was due to sex inequality, high transport costs to access the services, inadequate posttest counseling, lack of HIV status disclosure, and the isolated/exposed location of the ART clinic, which robs the clients of their privacy.Conclusion: There is a need for approaches that empower women with social capital, knowledge, and skills to influence health-seeking practices. There is also a need to train low-ranking staff and take PMTCT services closer to the clients at the lower-level units to make them affordable and accessible to rural clients. Posttest counseling should be improved to enable PMTCT clients to appreciate the importance of PMTCT services through increasing the number of staff in antenatal care to match the client numbers for improved quality. The counseling should emphasize HIV status disclosure to

    To assess whether implementation of a prevention of mother-to-child HIV transmission (PMTCT) programme in Côte d'Ivoire improved the quality of antenatal and delivery care services. Quality of antenatal and delivery care services was assessed in five urban health facilities before (2002-2003) and after (2005) the implementation of a PMTCT programme through review of facility data; observation of antenatal consultations (n = 606 before; n = 591 after) and deliveries (n = 229 before; n = 231 after) and exit interviews of women; and interviews of health facility staff. HIV testing was never proposed at baseline and was proposed to 63% of women at the first ANC visit after PMTCT implementation. The overall testing rate was 42% and 83% of tested HIV-infected pregnant women received nevirapine. In addition, inter-personal communication and confidentiality significantly improved in all health facilities. In the maternity ward, quality of obstetrical care at admission, delivery and post-partum care globally improved in all facilities after the implementation of the programme although some indicators remained poor, such as filling in the partograph directly during labour. Episiotomy rates among primiparous women dropped from 64% to 25% (P implementation. Global scores for quality of antenatal and delivery care significantly improved in all facilities after the implementation of the programme. Introducing comprehensive PMTCT services can improve the quality of antenatal and delivery care in general.

    Full Text Available Background. We determined the incidence of HIV seroconversion during the second and third trimesters of pregnancy and ad hoc potential cofactors associated with HIV seroconversion after having an HIV-negative result antenatally. We also studied knowledge of PMTCT among pregnant women in seven health facilities in Fako Division, South West Region, Cameroon. Method. During the period between September 12 and December 4, 2011, we recruited a cohort of 477 HIV-negative pregnant women by cluster sampling. Data collection was with a pretested interviewer-administered questionnaire. Sociodemographic information, knowledge of PMTCT, and methods of HIV prevention were obtained from the study population and we did Voluntary Counselling and Testing (VCT for HIV. Results. The incidence rate of HIV seroconversion during pregnancy was 6.8/100 woman-years. Ninety percent of the participants did not use condoms throughout pregnancy but had a good knowledge of PMTCT of HIV. Only 31.9% of participants knew their HIV status before the booking visit and 33% did not know the HIV status of their partners. Conclusion. The incidence rate of HIV seroconversion in the Fako Division, Cameroon, was 6.8/100 woman-years. No risk factors associated with HIV seroconversion were identified among the study participants because of lack of power to do so.

    We determined the incidence of HIV seroconversion during the second and third trimesters of pregnancy and ad hoc potential cofactors associated with HIV seroconversion after having an HIV-negative result antenatally. We also studied knowledge of PMTCT among pregnant women in seven health facilities in Fako Division, South West Region, Cameroon. During the period between September 12 and December 4, 2011, we recruited a cohort of 477 HIV-negative pregnant women by cluster sampling. Data collection was with a pretested interviewer-administered questionnaire. Sociodemographic information, knowledge of PMTCT, and methods of HIV prevention were obtained from the study population and we did Voluntary Counselling and Testing (VCT) for HIV. The incidence rate of HIV seroconversion during pregnancy was 6.8/100 woman-years. Ninety percent of the participants did not use condoms throughout pregnancy but had a good knowledge of PMTCT of HIV. Only 31.9% of participants knew their HIV status before the booking visit and 33% did not know the HIV status of their partners. The incidence rate of HIV seroconversion in the Fako Division, Cameroon, was 6.8/100 woman-years. No risk factors associated with HIV seroconversion were identified among the study participants because of lack of power to do so.

    The 2016 World Health Organization (WHO) consolidated guideline recommends lifelong antiretroviral therapy (ART) for all HIV-infected pregnant and breastfeeding women for preventing mother-to-child HIV transmission (PMTCT). Ambiguity remains about the cost-effectiveness of this strategy in resource-limited developing countries. Areas covered: We reviewed model-based studies on the cost-effectiveness of lifelong ART (formerly Option B+) relative to previous WHO guidelines for PMTCT. Our search using PubMed, Medline and Google Scholar for articles on Option B+ resulted in the final inclusion of seven studies published between 2012 and 2016. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to assess the quality of reporting. Outcomes of interest, which included infant infections averted, maternal quality and length of life, and the Incremental Cost Effectiveness Ratio (ICER), were used in comparing cost-effectiveness. Expert commentary: Despite most model-based studies favouring lifelong ART (Option B+) in terms of its cost-effectiveness in comparison to Options A and B, inclusiveness of the evidence remains weak for generalization. This is largely because setting specificity for providing lifelong ART to all pregnant and breastfeeding women may differ significantly in each setting. Consequently, future cost-effectiveness studies should be robust, setting-specific, and endeavor to assess the willingness and ability to pay of each setting.

    In Burkina Faso, prolonged breastfeeding with introduction of ritual fluids from birth is a deep-seated norm. We explored HIV-infected mothers' views and experiences of the acceptability and feasibility of the World Health Organization's recommended infant-feeding options within a mother-to-child-transmission prevention trial. A qualitative study was conducted on 17 formula-feeding and 19 breastfeeding mothers, from a larger cohort of 51 eligible HIV-infected women, consenting to participate in separate focus group discussions in early post-partum. Mothers opted for breastfeeding essentially out of fear of family rejection. Most of them were afraid of denigration for disrespecting tradition if they formula-fed or being suspected of HIV infection. Achieving exclusive breastfeeding remained a difficult challenge as they engaged in a continuous struggle with close elders to avoid fluid feeding. Additional stress and fatigue were fed by their perception of a high transmission risk through breast milk. Exclusive formula-feeding seemed easier to implement, especially as formula was provided free of charge. Formula-feeding mothers more frequently had a supportive partner, a strong personality and lived in better socio-economic conditions than breastfeeding mothers (76% had education and electricity supply vs. 42%, respectively). Exclusive breastfeeding for the first 6 months remains the most appropriate option for many HIV-infected mothers in sub-Saharan Africa. Its acceptability and feasibility urgently need to be improved by promoting it as the best feeding option for all infants. Other crucial interventions are the promotion of voluntary counselling and testing for couples, and greater partner involvement in infant-feeding counselling.

    Full Text Available Abstract Background According to Vietnamese policy, HIV-infected women should have access at least to HIV testing and Nevirapine prophylaxis, or where available, to adequate counselling, HIV infection staging, ARV prophylaxis, and infant formula. Many studies in high HIV prevalence settings have reported low coverage of PMTCT services, but there have been few reports from low HIV prevalence settings, such as Asian countries. We investigated the access of HIV-infected pregnant women to PMTCT services in the well-resourced setting of the capital city, Hanoi. Methods Fifty-two HIV positive women enrolled in a self-help group in Hanoi were consulted, through in-depth interviews and bi-weekly meetings, about their experiences in accessing PMTCT services. Results Only 44% and 20% of the women had received minimal and comprehensive PMTCT services, respectively. Nine women did not receive any services. Twenty-two women received no counselling. The women reported being limited by lack of knowledge and information due to poor counselling, gaps in PMTCT services, and fear of stigma and discrimination. HIV testing was done too late for optimal interventions and poor quality of care by health staff was frequently mentioned. Conclusion In a setting where PMTCT is available, HIV-infected women and children did not receive adequate care because of barriers to accessing those services. The results suggest key improvements would be improving quality of counselling and making PMTCT guidelines available to health services. Women should receive early HIV testing with adequate counselling, safe care and prophylaxis in a positive atmosphere towards HIV-infected women.

    The WHO 2010 guidelines for prevention of mother-to-child transmission (PMTCT) of HIV recommended prophylactic antiretroviral treatment (ART) either for infants (Option A) or mothers (Option B) during breastfeeding for pregnant women with a CD4 count of >350 cell/µL in low-income countries. In 2012, WHO proposed that all HIV-infected pregnant women should receive triple ART for life (B+) irrespective of CD4 count. Tanzania has recently switched from Option A to B+, with a few centers practicing B. However, more information on the real-life feasibility of these options is needed. This qualitative study explored women's preferences for Option A vs B and their views on Option B+ in Dar es Salaam, Tanzania. We conducted four focus group discussions with a total of 27 pregnant women with unknown HIV status, attending reproductive and child health clinics, and 31 in-depth interviews among HIV-infected pregnant and post-delivery women, 17 of whom were also asked about B+. Most participants were in favor of Option B compared to A. The main reasons for choosing Option B were: HIV-associated stigma, fear of drug side-effects on infants and difficult logistics for postnatal drug adherence. Some of the women asked about B+ favored it as they agreed that they would eventually need ART for their own survival. Some were against B+ anticipating loss of motivation after protecting the child, fearing drug side-effects and not feeling ready to embark on lifelong medication. Some were undecided. Option B was preferred. Since Tanzania has recently adopted Option B+, women with CD4 counts of >350 cell/µL should be counseled about the possibility to "opt-out" from ART after cessation of breastfeeding. Drug safety and benefits, economic concerns and available resources for laboratory monitoring and evaluation should be addressed during B+ implementation to enhance long-term feasibility and effectiveness.

    Zimbabwe is one of the five countries worst affected by the HIV/AIDS pandemic with HIV infection contributing increasingly to childhood morbidity and mortality. Among the children born to HIV positive mothers participating in the PMTCT programme, 25% tested positive to HIV. We investigated factors associated with HIV infection among children born to mothers on the PMTCT programme. A 1:1 unmatched case-control study was conducted at Chitungwiza Hospital, Zimbabwe, 2008. A case was defined as a child who tested HIV positive, born to a mother who had been on PMTCT programme. A control was a HIV negative child born to a mother who had been on PMTCT programme. An interviewer-administered questionnaire was used to collect data on demographic characteristics, risk factors associated with HIV infection and immunization status. A total of 120 mothers were interviewed. Independent risk factors associated with HIV infection among children included maternal CD4 count of less than 200 during pregnancy [aOR = 7.1, 95% CI (2.6-17)], mixed feeding [aOR = 29, 95% CI (4.2-208)], being hospitalized since birth [aOR = 2.9, 95% CI (1.2-4.8)] whilst being exclusively breast fed for less than 6 months [aOR = 0.1 (95% CI 0.03-0.4)] was protective. HIV infection among children increased if the mother's CD4 count was ≤200 cells/μL and if the child was exposed to mixed feeding. Breastfeeding exclusively for less than six months was protective. We recommended exclusive breast feeding period for the first six months and stop breast feeding after 6 months if affordable, sustainable and safe.

    South Africa (SA) has the highest burden of childhood HIV infection globally, and has high rates of adolescent and youth pregnancy. To explore risks associated with pregnancy in young HIV-infected women, we compared mother-to-child transmission (MTCT) of HIV and maternal and infant health outcomes according to maternal age categories. A cohort of HIV-positive pregnant women and their infants were followed up at three sentinel surveillance facilities in the Nelson Mandela Bay Metropolitan (NMBM) district, Eastern Cape Province, SA. Young women were defined as 24 years old and adolescents as 19 years. The effect of younger maternal age categories on MTCT and maternal and child health outcomes was assessed using log-binomial and Cox regression controlling for confounding, using women aged > 24 years as the comparison group. Of 956 mothers, 312 (32.6%) were young women; of these, 65 (20.8%) were adolescents. The proportion of young pregnant women increased by 24% between 2009/10 and 2011/12 (from 28.3% to 35.1%). Young women had an increased risk of being unaware of their HIV status when booking (adjusted risk ratio (aRR) 1.37; 95% confidence interval (CI) 1.21 - 1.54), a reduced rate of antenatal antiretroviral therapy (ART) uptake (adjusted hazard ratio 0.46; 95% CI 0.31 - 0.67), reduced early infant HIV diagnosis (aRR 0.94; 95% CI 0.94 - 0.94), and increased MTCT (aRR 3.07; 95% CI 1.18 - 7.96; adjusted for ART use). Of all vertical transmissions, 56% occurred among young women. Additionally, adolescents had increased risks of first presentation during labour (aRR 3.78; 95% CI 1.06 - 13.4); maternal mortality (aRR 35.1; 95% CI 2.89 - 426) and stillbirth (aRR 3.33; 95% CI 1.53 - 7.25). An increasing proportion of pregnant HIV-positive women in NMBM were young, and they had increased MTCT and poorer maternal and infant outcomes than older women. Interventions targeting young women are increasingly needed to reduce pregnancy, HIV infection and MTCT and improve maternal

    2011-12-01

    The World Health Organization (WHO) and United Nations Programme on HIV/AIDS (UNAIDS) estimated that an additional 370 000 new human immunodeficiency virus type 1 (HIV-1) infections occurred in children in 2009, mainly through mother-to-child transmission (MTCT). Intrapartum transmission contributes to approximately 20-25% of infections, in utero transmission to 5-10% and postnatal transmission to an additional 10-15% of cases. MTCT accounts for only a few hundred infected newborns in those countries in which services are established for voluntary counselling and testing of pregnant women, and a supply of antiretroviral drugs is available throughout pregnancy with recommendations for elective Caesarean section and avoidance of breastfeeding. The single-dose nevirapine regimen has provided the momentum to initiate MTCT programmes in many resource-limited countries; however, regimens using a combination of antiretroviral drugs are needed also to effectively reduce transmission via breastfeeding. 2011 The Association for the Publication of the Journal of Internal Medicine.

    We evaluated maternal CD4+ cell count (CD4+) decline after PMTCT prophylaxis in a multi-country HIV care program. Analysis was restricted to antiretroviral therapy (ART)-naive, HIV-infected pregnant women with CD4+ ≥250 cells/mm(3) at enrollment. Single-dose nevirapine (sd-NVP) or short-course antiretroviral prophylaxis (sc-ARVp) with zidovudine (AZT) or AZT + lamivudine (3TC) was initiated in 11 programs while 2 programs offered triple-drug antiretroviral prophylaxis (tARVp) (AZT+3TC+ NVP or nelfinavir). All regimens were stopped at delivery. CD4+ decline was defined as proportion of women who declined to CD4+ cells/mm(3) or cells/mm(3) at 24 months. Weibull regression was used for multivariable analysis. A total of 1,393 women with enrollment CD4+ ≥250 cells/mm(3) initiated tARVp (172; 12%) or sc-ARVp (532; 38%) during pregnancy or received intrapartum sd-NVP (689; 50%). At enrollment, maternal median age was 27 years (interquartile range (IQR) 23-30), median CD4+ was 469 cells/mm(3) (IQR: 363-613). At 24 months post-delivery, the cumulative probability of CD4+ decline to cells/mm(3) was 12% (95% CI: 10-14). Among a subgroup of 903 women with CD4+ ≥400 cells at enrollment, the 24 month cumulative probability of decline to CD4+ cells/mm(3) was 28%; (95% CI: 25-32). Lower antepartum CD4+ was associated with higher probability of CD4+ decline to cells/mm(3): 46% (CD4+400-499 cells/mm(3)) vs. 19% (CD4+ ≥500 cells/mm(3)). After adjusting for age, enrollment CD4+ and WHO stage, women who received tARVp or sd-NVP were twice as likely to experience CD4+ decline to cells/mm(3) within 24 months than women receiving sc-ARVp (adjusted hazard ratio: 2.2; 95% CI: 1.5-3.2, pcell count to ART eligibility thresholds by 24 months postpartum was common among women receiving PMTCT prophylaxis during pregnancy and/or delivery.

    The prevalence of anaemia during pregnancy is estimated to be 35-75% in sub-Saharan Africa and is associated with an increased risk of maternal mortality. We evaluated the frequency and factors associated with anaemia in HIV-infected women undergoing antiretroviral (ARV) therapy for prevention of mother-to-child transmission (PMTCT) enrolled in The Kisumu Breastfeeding Study 2003-2009. Maternal haematological parameters were monitored from 32 to 34 weeks of gestation to 2 years post-delivery among 522 enrolled women. Clinical and laboratory assessments for causes of anaemia were performed, and appropriate management was initiated. Anaemia was graded using the National Institutes of Health Division of AIDS 1994 Adult Toxicity Tables. Data were analysed using SAS software, v 9.2. The Wilcoxon two-sample rank test was used to compare groups. A logistic regression model was fitted to describe the trend in anaemia over time. At enrolment, the prevalence of any grade anaemia (Hb anaemia (Hb anaemia events occurred around delivery (48.8%; n = 20).

    Background Mitochondrial toxicity was described in infants exposed to long-term antiretroviral regimens (ARVs) containing nucleoside analogues for the prevention of mother-to-child transmission of HIV (PMTCT). We measured the serum lactate levels in children born to HIV-1 infected (HIV+) African women receiving short-term ARV PMTCT regimens. Methods A prospective study was conducted in women-child pairs from the third trimester of pregnancy to three months of life. The exposed group was formed by children exposed in utero to nucleoside analogue ARVs, zidovudine (ZDV) or ZDV + lamivudine (3TC) from 32–36 weeks of amenorrhea until delivery. All these women received nevirapine single-dose (NVPsd) at the beginning of labor. The children received ZDV during the first 7 days of life and a NVPsd at day 3. The control group was formed by infants born to HIV+ women who had received NVPsd only and not exposed to nucleoside analogue ARVs. Serum lactate levels were measured at 4, 6 and 12 weeks of life by Cobas Integra 400™. Results A total of 836 blood samples from 338 infants were collected (262 exposed and 76 controls). Median lactacidemia was 1.8 mmol/l, Interquartile Range [1.2–2.7 mmol/l]). Overall serum lactate levels ≥2.5 mmol/l, defining hyperlactatemia were observed in 39 of the 292 infants who had at least two serum lactate measurements, 13.4%, 95% confidence Interval [9.6–17.8%]. The three-month period prevalence of hyperlactatemia did not differ between the exposed group (13.1%) and the control group (14.3%) (p=0.84). All serum lactate levels returned to normal values in all subsequent samples No case of symptomatic hyperlactatemia was detected during the study period. Conclusion Increased lactate levels were identified equally in infants whose mother received a short-term of nucleoside analogues or NVPsd for PMTCT. Although not rare, hyperlactatemia was not related to short-term exposure to nucleoside analogue ARVs PMID:16950945

    Improving retention in prevention of mother to child transmission (PMTCT) of HIV programs is critical to optimize maternal and infant health outcomes, especially now that lifelong treatment is immediate regardless of CD4 cell count). The WelTel strategy of using weekly short message service (SMS) to engage patients in care in Kenya, where mobile coverage even in poor areas is widespread has been shown to improve adherence to antiretroviral therapy (ART) and viral load suppression among those on ART. The aim of this study is to determine the effect of the WelTel SMS intervention compared to standard care on retention in PMTCT program in Kenya. WelTel PMTCT is a four to seven-centers, two-arm open randomized controlled trial (RCT) that will be conducted in urban and rural Kenya. Over 36 months, we plan to recruit 600 pregnant women at their first antenatal care visit and follow the mother-infant pair until they are discharged from the PMTCT program (when infant is aged 24 months). Participants will be randomly allocated to the intervention or control arm (standard care) at a 1:1 ratio. Intervention arm participants will receive an interactive weekly SMS 'How are you?' to which they are supposed to respond within 24 h. Depending on the response (ok, problem or no answer), a PMTCT nurse will follow-up and triage any problems that are identified. The primary outcome will be retention in care defined as the proportion of mother-infant pairs coming for infant HIV testing at 24 months from delivery. Secondary outcomes include a) adherence to WelTel; (b) adherence to antiretroviral medicine; (c) acceptance of WelTel and (d) cost-effectiveness of the WelTel intervention. This trial will provide evidence on the effectiveness of mHealth for PMTCT retention. Trial results and the cost-effectiveness evaluation will be used to inform policy and potential scale-up of mHealth among mothers living with HIV. ISRCTN98818734 ; registered on 9th December 2014.

Each institution included in the VDP provided data on program implementation, type of management institution, number of PMTCT sites, key programs outputs (HIV counseling and testing, NVP regimens received by mothers and newborns. Nevirapine Coverage Ratio (NCR, defined as the number of women who should have received nevirapine (observed HIV prevalence x number of women in antenatal care, was used to measure performance. Included programs were followed every six months through progress reports.A total of 64 programs in 25 sub-Saharan African countries were included. The mean program follow-up was 48.0 months (SD = 24.5; 20,084,490 women attended in antenatal clinics were included. The overall mean NCR was 0.52 (SD = 0.25, with an increase from 0.37 to 0.57 between the first and last progress reports (p<.0001; NCR increased by 3.26% per year-program.

    The Millennium Villages Project (MVP) implemented in Western Kenya a mobile Health tool that uses text messages to coordinate Community Health Worker (CHW) activities around antenatal care (ANC) and Prevention of Mother-to-Child Transmission of HIV (PMTCT), named the ANC/PMTCT Adherence System (APAS). End-user changes in health-seeking behavior in ANC and postnatal care (PNC) were investigated following registration of 800 women into APAS. These investigations employed interviews of pregnant women or new mothers (n = 67) and CHWs (n = 20). Ordinal logistic regressions and exact binomial tests were used in the routine data analyses (n = 650, health registers). All CHWs interviewed agreed that APAS helped them track pregnant woman efficiently, compared to paper-based tracking forms. Women registered in APAS reported that CHWs reminded them of appointments more regularly than before its inception. The routine data analysis showed that among women who had their 1(st) ANC visit in the 2(nd) trimester, women who resided in the MVP cluster and were in APAS had: 3 times the odds of going for more ANC visits compared to women who were not registered (but resided in the cluster), after adjusting for the mother's HIV status in the multivariate model (Adjusted OR = 2.58, 95% CI [1.10-6.01]); twice the odds of going for more ANC visits compared to women who were not registered and resided outside the cluster (Adjusted OR = 2.37, 95% CI [0.99-5.67]) Among women not registered, residence inside or outside the cluster did not affect the number of ANC visits made (Adjusted OR = 0.86, 95% CI [0.45-1.69]). The APAS also greatly increased the likelihood of women making the 6 recommended post-delivery baby follow-ups. For women registered in APAS, the MTCT rate at 18 months was significantly different from that of women not registered, and from the global rate of 30%. Women not registered had a 9% MTCT rate at 18 months regardless of residence, while women registered had a 0

    Efforts to scale up and improve programs for prevention of mother-to-child transmission of HIV (PMTCT) have focused primarily at the health facility level, and limited attention has been paid to defining an effective set of community interventions to improve demand and uptake of services and retention. Many barriers to PMTCT are also barriers to pregnancy, childbirth, and postnatal care faced by mothers regardless of HIV status. Demand for maternal and child health (MCH) and PMTCT services can be limited by critical social, cultural, and structural barriers. Yet, rigorous evaluation has shown limited evidence of effectiveness of multilevel community-wide interventions aimed at improving MCH and HIV outcomes for pregnant women living with HIV. We propose to assess the effect of a package of multilevel community interventions: a social learning and action component, community dialogues, and peer-led discussion groups, on the demand for, uptake of, and retention of HIV positive pregnant/postpartum women in MCH/PMTCT services. This study will undertake a three-arm randomized trial in Swaziland, Uganda, and Zimbabwe. Districts/regions (n = 9) with 45 PMTCT-implementing health facilities and their catchment areas (populations 7,300-27,500) will be randomly allocated to three intervention arms: 1) community leader engagement, 2) community leader engagement with community days, or 3) community leader engagement with community days and male and female community peer groups. The primary study outcome is HIV exposed infants (HEIs) returning to the health facility within 2 months for early infant diagnosis (EID) of HIV. Secondary study outcomes include gestational age of women attending for first antenatal care, male partners tested for HIV, and HEIs receiving nevirapine prophylaxis at birth. Changes in community knowledge, attitudes, practices, and beliefs on MCH/PMTCT will be assessed through household surveys. Implementation of the protocol necessitated changes in the

    University, Cape Town, South Africa Objective: To examine the acceptability and feasibility of mobile health (mHealth/short message service (SMS and community-based directly observed antiretroviral therapy (cDOT as interventions to improve antiretroviral therapy (ART adherence for preventing mother-to-child human immunodeficiency virus (HIV transmission (PMTCT. Design and methods: A mixed-method approach was used. Two qualitative focus group discussions with HIV-infected pregnant women (n=20 examined the acceptability and feasibility of two ART adherence interventions for PMTCT: 1 SMS text messaging and 2 patient-nominated cDOT supporters. Additionally, 109 HIV-infected, pregnant South African women (18–30 years old receiving PMTCT services under single-tablet antiretroviral therapy regimen during pregnancy and breastfeeding and continuing for life (“Option B+” were interviewed about mobile phone access, SMS use, and potential treatment supporters. Setting: A community primary care clinic in Cape Town, South Africa. Participants: HIV-infected pregnant women. Main outcomes: Acceptability and feasibility of mHealth and cDOT interventions. Results: Among the 109 women interviewed, individual mobile phone access and SMS use were high (>90%, and 88.1% of women were interested in receiving SMS ART adherence support messages such as reminders, motivation, and medication updates. Nearly all women (95% identified at least one person close to them to whom they had disclosed their HIV status and would nominate as a cDOT supporter. Focus group discussions revealed that cDOT supporters and adherence text messages were valued, but some concerns regarding supporter time availability and risk of unintended HIV status disclosure were expressed. Conclusion: mHealth and/or cDOT supporter as interventions to improve ART adherence are feasible in this setting. However, safe HIV status disclosure to treatment supporters and confidentiality of text messaging content about HIV and ART were

METHODS: All pregnant, HIV-positive women who attended the major HIV testing and treatment clinic in Port-au-Prince, Haiti, between March 1999 and December 2004 were asked to participate in an MTCT prevention program. Of the 650 women who participated, 73.3% received zidovudine (AZT, 2.9% received nevirapine (NVP, and 10.1% received triple-drug therapy when it became available in 2003 and if clinical/laboratory indications were met. Approximately 13.8% received no antiretroviral medication. All participants received cotrimoxazole prophylaxis and infant formula for their children. Kaplan-Meier survival analysis and the log rank test were used to evaluate program impact on child survival. RESULTS: Complete data were available for 348 mother-infant pairs who completed the program to prevent MTCT of HIV. The rate of MTCT in the study was 9.2% (95% CI: 6.14-12.24, in contrast to the historical mother-to-child transmission rate of 27% in Haiti.

    Full Text Available Male involvement (MI is vital for the uptake of Prevention of Mother to Child Transmission (PMTCT of Human Immunodeficiency Virus (HIV interventions. Partner notification (PN is among the strategies identified for MI in PMTCT services. The purpose of this randomized controlled trial was to evaluate the efficacy of an invitation card to the male partners as a strategy for MI in PMTCT services by comparing the proportion of pregnant women that were accompanied by their partners between the intervention and the non-intervention study groups.Pregnant women attending antenatal care without a male partner at South Lunzu and Mpemba health centres in Blantyre, Malawi, were enrolled in the study from June to December 2013. In an intention-to-treat analysis, we compared all participants that were randomized in the invitation card group with the standard of care (SoC group. Risk ratios (RR with 95% confidence intervals (CI were computed to assess the efficacy of the invitation card.Of the 462 randomized women, 65/230 (28.26% of the women in the invitation card group reported to the antenatal care clinic with their partners compared to 44/232 (18.97% women in the SoC group.

    Full Text Available Abstract Background HIV prevalence among pregnant women in Malawi is 12.6%, and mother-to-child transmission is a major route of transmission. As PMTCT services have expanded in Malawi in recent years, we sought to determine uptake of services, HIV-relevant infant feeding practices and mother-child health outcomes. Methods A matched-cohort study of HIV-infected and HIV-uninfected mothers and their infants at 18-20 months post-partum in Zomba District, Malawi. 360 HIV-infected and 360 HIV-uninfected mothers were identified through registers. 387 mother-child pairs were included in the study. Results 10% of HIV-infected mothers were on HAART before delivery, 27% by 18-20 months post-partum. sd-NVP was taken by 75% of HIV-infected mothers not on HAART, and given to 66% of infants. 18% of HIV-infected mothers followed all current recommended PMTCT options. HIV-infected mothers breastfed fewer months than HIV-uninfected mothers (12 vs.18, respectively; p p Conclusion This study shows low PMTCT program efficiency and effectiveness under routine program conditions in Malawi. HIV-free infant survival may have been influenced by key factors, including underuse of HAART, underuse of sd-NVP, and suboptimal infant feeding practices. Maternal mortality among HIV-infected women demands attention; improved maternal survival is a means to improve infant survival.

    Full Text Available The rate of mother-to-child transmission (MTCT of HIV as well as the implications of the circulating multiple subtypes to MTCT in Nigeria are not known. This study was therefore undertaken to determine the differential rates of MTCT of HIV-1 subtypes detected among infected pregnant women before ARV intervention therapy became available in Nigeria. Twenty of the HIV-positive women who signed the informed consent form during pregnancy brought their babies for follow-up testing at age 18-24 months. Plasma samples from both mother and baby were tested for HIV antibody at the Department of Virology, UCH, Ibadan, Nigeria. All positive samples (plasma and peripheral blood mononuclear cells - PBMCs were shipped to the Institute of Tropical Medicine, Antwerp, Belgium, where the subtype of the infecting virus was determined using the HMA technique. Overall, a mother-to-child HIV transmission rate of 45% was found in this cohort. Specifically, 36.4%, 66.7% and 100% of the women infected with HIV-1 CRF02 (IbNg, G and B, respectively, transmitted the virus to their babies. As far as it can be ascertained, this is the first report on the rate of MTCT of HIV in Nigeria.

    There is evidence that the borderline symptomatology of the mother longitudinally predicts the number of borderline criteria met by the children. However, possible underlying mechanisms have rarely been examined. In line with transactional models of borderline personality disorder (BPD), we analyzed a broad concept of maladaptive mother-child interactions of mothers with BPD symptoms towards their children, including insensitive parenting and mother-child discrepancies, in reporting the child's psychopathological behavior. SAMPLING/METHODS: The sample was drawn from the population-based Greifswald Family Study and consisted of 295 children and their biological mothers. Both were examined at two points in time, first when the children were about 15 years old (T0) and again 5 years later (T1), using path analyses. Maladaptive mother-child interactions (especially an overprotective and rejecting parenting style and high discrepancies regarding internalizing problems) mediate the longitudinal transmission of borderline symptoms from mother to child. Furthermore, our data revealed that this result is consistent for various youth symptoms which are associated with BPD such as impulsivity or dissociation. The data of the current study imply that the transmission of borderline symptoms from mother to child is mediated by maladaptive mother-child interactions. For this reason early and professional support may be useful to prevent these children from developing severe psychopathology. Copyright © 2012 S. Karger AG, Basel.

  12. Current Perspectives on Prevention of Mother-to-Child Transmission of Syphilis

    2016-01-01

    This article aims to provide an update on the prevention of mother-to-child transmission of syphilis by drawing upon some important basic concepts and reviewing the most recent literature on the diagnosis and treatment of syphilis in pregnancy. New technologies, such as automated and point-of-care immunologic tests, are shifting some paradigms, which will certainly be further investigated in the forthcoming years. This is the time to carefully evaluate traditional as well as new strategies to prevent congenital syphilis. Adverse outcomes of mother-to-child transmission of syphilis can be prevented with antenatal screening and penicillin therapy, which proved to have an excellent cost-benefit ratio even in populations with a low prevalence of syphilis. However, syphilis epidemiology is influenced by socioeconomic and cultural factors, and major challenges are faced by poor and developing countries in which the severity of the problem is extremely alarming. On the other hand, the emergence of new technologies has raised doubts about the best algorithm to be used when proper laboratory resources are available. Conditions are quite heterogeneous across populations, and some procedures should not be generalized while there is no evidence that supports some changes and while in-depth studies about local conditions are not conducted. Official organizations need to be alert in order to avoid isolated decisions and ensure that evidence-based guidelines be used in the management of syphilis in pregnancy. PMID:27081586

    Health behaviors play a major role in the prevention of the most common oral diseases. To investigate health behaviors related to the potential transmission of oral bacteria from mother to child using novel multiple correspondence analysis (MCA). Mothers (n = 313) with children under three years attending two municipal child health clinics in Finland completed a self-administered questionnaire on health knowledge and behaviors such as sharing a spoon with their child, kissing on the lips, and the mothers' tooth brushing, smoking, age, and level of education. We used MCA to reveal the relationships between the mothers' behaviors and background factors, along with unconditional, binary, multivariable logistic regression models, odds ratios (OR) and their 95 % confidence intervals (95 %CI). Of the mothers, 38 % kissed their child on the lips and 14 % shared a spoon with their child; 11 % believed that oral bacteria cannot be transmitted from mother to child. Two-thirds (68 %) of them reported tooth brushing twice daily, and 80 % were non-smokers. MCA revealed two diverging dimensions of the mothers' behaviors: a 'horizontal' one showing clear evidence of relationships between tooth brushing, smoking, age and education, whereas the 'vertical' one revealed the mothers' habits of kissing the child on the lips and sharing a spoon related to each other. Spoon sharing was related to the kissing on lips (OR 10.3), a higher level of education (OR 3.1), and, inversely, older age (OR 0.1), whereas kissing on lips behavior was inversely related to a higher level of education (OR 0.5). The study revealed two diverging dimensions of the mothers' health behaviors. More emphasis in health education ought to be put to how to avoid bacterial transmission from caregiver to child during feeding.

    More than 90% of Human immunodeficiency virus (HIV) infection in children is acquired due to mother-to-child transmission, which is spreading during pregnancy, delivery or breastfeeding. To determine the effectiveness of highly active antiretroviral and short course antiretroviral regimens in prevention of mother-to-child transmission of HIV and associated factors Jimma University Specialized Hospital (JUSH). A hospital based retrospective cohort study was conducted on HIV infected pregnant mothers who gave birth and had follow up at anti-retroviral therapy (ART) clinic for at least 6 months during a time period paired with their infants. The primary and secondary outcomes were rate of infant infection by HIV at 6 weeks and 6 months respectively. The Chi-square was used for the comparison of categorical data multivariate logistic regression model was used to identify the determinants of early mother-to-child transmission of HIV at 6 weeks. Cox proportional hazard model was used to analyze factors that affect the 6 month HIV free survival of infants born to HIV infected mothers. A total of 180 mother infant pairs were considered for the final analysis, 90(50%) mothers received single dose nevirapine (sdNVP) designated as regimen-3, 67 (37.2%) mothers were on different types of ARV regimens commonly AZT + 3TC + NVP (regimen-1), while the rest 23 (12.8%) mothers were on short course dual regimen AZT + 3TC + sdNVP (regimen-2). Early mother-to-child transmission rate at 6 weeks for regimens 1, 2 and 3 were 5.9% (4/67), 8.6% (2/23), and 15.5% (14/90) respectively. The late cumulative mother-to-child transmission rate of HIV at 6 months regardless of regimen type was 15.5% (28/180). Postnatal transmission at 6 months was 28.5% (8/28) of infected children. Factors that were found to be associated with high risk of early mother-to-child transmission of HIV include duration of ARV regimen shorter than 2 months during pregnancy (OR=4.3, 95%CI =1.38-13.46), base line CD4 less

    Full Text Available In Brazil, syphilis and HIV infection are considered serious public health problems. However, in practice, epidemiological surveillance, prevention measures, and prenatal care seem to be more effective in the control of mother-to-child transmission of the HIV than in the control of transmission of the Treponema pallidum. Here we discuss the differences in surveillance, prenatal care, and care of the newborn. Important differences were identified. It is concluded that there is an urgent need to establish prevention of mother-to-child transmission of syphilis as a public health priority, using an integrated approach including women's health, children's health, primary health care, and STD/AIDS programs on all governmental levels. These issues also need to be discussed with all stakeholders involved. Important aspects related to the problem are the training of public health professionals, as well as the participation of the community. The elimination of congenital syphilis does not require expensive drugs, and diagnostic tools, but a long-term sustainable approach.No Brasil, a infecção pelo Treponema pallidum e pelo vírus da imunodeficiência humana são eventos considerados prioritários. No entanto, apesar das políticas públicas, a resposta em termos das ações de vigilância e prevenção, assistência pré-natal e ao recém-nascido, é diferenciada, parecendo ser mais bem estruturada para a redução da transmissão vertical do HIV do que para a do T. pallidum. No presente artigo, potenciais diferenças são analisadas quanto ao desenvolvimento das ações. Identificou-se que as desigualdades existentes na atenção aos dois problemas apresentam dimensões diferenciadas nas regiões do país. Reconheceu-se a necessária e urgente priorização da sífilis na gravidez, envolvendo áreas técnicas como atenção básica, saúde da mulher, saúde da criança e controle de doenças sexualmente transmissíveis, em todas as esferas de governo

    Full Text Available Abstract Background Mother -to -Child transmission of hepatitis B infection remains a major public health concern particularly in Africa. Adequate knowledge of physicians and midwives is crucial in averting most of the hepatitis B viral transmissions from mothers to their new-borns. However, there is a dearth of evidence on extent of knowledge of physicians and midwives in Ghana inspite of the increasing incidence of hepatitis B infection in the country. This study therefore assessed the knowledge level of physicians and midwives regarding Mother-to-Child transmission of hepatitis B in the Eastern region of Ghana. Methods A Cross sectional survey was conducted between August to November, 2015 using semi-structured self-administered questionnaire. Study participants were recruited from five health facilities and their level of awareness and knowledge about Mother-to-Child transmission of hepatitis B were assessed. The level of statistical significance was set at 0.05 alpha level. Results The findings showed that both physicians and midwives had good knowledge on Mother-to-Child transmission of hepatitis B infection. However, there were some knowledge gaps regarding effective hepatitis B prevention from mother to their newborns such as the use of hepatitis B vaccine and immunoglobulin. Additionally, 49.2 % (n = 62 of the participants had never attended any workshop on Mother-to-Child transmission of hepatitis B since completion of formal training. Conclusions Developing appropriate periodic training programmes on current issues of hepatitis B for physicians and midwives in Eastern region will further enhance their knowledge. It is recommended that, further study examine if the knowledge of the respondents is translated into practice.

    Full Text Available Beliefs can influence health behavior. This qualitative study aimed to understand the beliefs that influence HIV positive mothers' behaviors towards prevention methods against mother-to-child transmission. Fourteen women were interviewed. Our research was based on the theoretical Health Belief Model, formed by the following dimensions: perceived susceptibility, perceived severity, perceived benefits and perceived obstacles. Data analysis showed reflections that evidence the paradox in the AIDS epidemic: knowledge does not change behavior; gender relations; fear of death; fear of stigma; financial problems; disbelief in the virus' existence. Identifying beliefs and understanding how to influence the conduction of the health problem can help services to promote patients' adherence.Las creencias son capaces de influenciar el comportamiento del hombre. El objetivo de este estudio cualitativo fue comprender las creencias que influencian el comportamiento de las madres HIV respecto a las medidas profilácticas de la transmisión vertical.

    The risk of mother-to-child transmission of hepatitis B virus (HBV) has been quoted as 70-90% among women positive for hepatitis B surface antigen (HBsAg) and e antigen (HBeAg), and 5-30% among HBsAg-positive HBeAg-negative women. These risks are derived from Asia; little is known about sub-Saharan Africa. To determine the risk of mother-to-child transmission in sub-Saharan Africa, according to maternal HBeAg and type of prophylaxis. We searched Medline, Global Health, Embase, African Journals Online and African Index Medicus. We included observational or interventional studies that enrolled infants of HBV-infected women, and that tested for HBsAg or HBV DNA between 3 and 12 months of age. Fifteen articles from 11 African countries were included. Among HBeAg-positive women, the pooled risk was 38.3% (95% CI: 7.0-74.4%) without prophylaxis, which was significantly lower than the lower bound of 70-90% risk in the literature (P = 0.007). Among HBeAg-negative women, the pooled risk was 4.8% (95% CI: 0.1-13.3%) without prophylaxis, which lays within the lower range of the 5-30% risk in Asia. By extrapolating the pooled transmission risks to the number of births to infectious mothers, an estimated 1% of newborns (n = 367 250) are annually infected with HBV at birth in sub-Saharan Africa. Compared to Asia, the risk of mother-to-child transmission is low in sub-Saharan Africa. However, the annual number of infants perinatally infected with HBV is twice the number of incident paediatric HIV infections in sub-Saharan Africa (n = 190 000). This highlights the importance of preventing mother-to-child transmission of HBV in sub-Saharan Africa, which has been long neglected. © 2016 John Wiley & Sons Ltd.

    Full Text Available Abstract Introduction Although progressive improvements have been made in the coverage and quality of prevention of HIV/AIDS mother-to-child transmission (PMTCT services in Ethiopia, the national coverage remained persistently low. Analysis of the cascaded PMTCT services can reveal the advancements made and the biggest hurdles faced during implementation. Objective To examine the progresses and unaddressed needs in access and utilization of PMTCT services in Ethiopia from 2006 to 2010 thereby developing best-fit regression models to predict the values of key PMTCT indicators at critical future points. Methods Five-year national level PMTCT data were analyzed in a cascaded manner. Five levels of analysis were used for ten major PMTCT indicators. These included description of progress made, assessment of unaddressed needs, developing best-fit models, prediction for future points and estimation using constant prevalence. Findings were presented using numerical and graphic summaries. Results Based on the current trend, Ethiopia could achieve universal ANC coverage by 2015. The prevalence of HIV at PMTCT sites has shown a four-fold decrease during the five-year period. This study has found that only 53% of known HIV-positive mothers and 48% of known HIV-exposed infants have received ARV prophylaxis. Based on assumption of constant HIV prevalence, the estimated ARV coverage was found to be 11.6% for HIV positive mothers and 8.4% for their babies. Conclusion There has been a remarkable improvement in the potential coverage of PMTCT services due to rapid increase in the number of PMTCT service outlets. However, the actual coverage remained low. Integration of PMTCT services with grassroots level health systems could unravel the problem.

    Full Text Available We assessed the integration of PMTCT services during the postpartum period including early infant diagnosis of HIV (EID and adult and pediatric antiretroviral therapy (ART in maternal and child health (MCH facilities in Zimbabwe.From August to December 2012 we conducted a cross-sectional survey of a nationally representative sample of 151 MCH facilities. A questionnaire was used to survey each site about staff training, dried blood spot sample (DBS collection, turnaround time (TAT for test results, PMTCT services, and HIV care and treatment linkages for HIV-infected mothers and children and HIV-exposed infants. Descriptive analyses were used. Of the facilities surveyed, all facilities were trained on DBS collection and 92% responded. Approximately, 99% of responding facilities reported providing DBS collection and a basic HIV-exposed infant service package including EID, extended nevirapine prophylaxis, and use of cotrimoxazole. DBS collection was integrated with immunisations at 83% of facilities, CD4 testing with point-of-care machines was available at 37% of facilities, and ART for both mothers and children was provided at 27% of facilities. More than 80% of facilities reported that DBS test results take >4 weeks to return; TAT did not have a direct association with any specific type of transport, distance to the lab, or intermediate stops for data to travel.Zimbabwe has successfully scaled up and integrated the national EID and PMTCT programs into the existing MCH setting. The long TAT of infant DBS test results and the lack of integrated ART programs in the MCH setting could reduce effectiveness of the national PMTCT and ART programs. Addressing these important gaps will support successful implementation of the 2014 Zimbabwe's PMTCT guidelines under which all HIV-infected pregnant and breastfeeding women will be offered life-long ART and decentralized ART care.

    The two neighboring southwestern states of India, Karnataka and Maharashtra, have high incidence of HIV/AIDS and are among the six most high prevalence HIV infected states. In Karnataka state, the northern districts of Bagalkot, Belgaum and Bijapur (the three Bs) and in Maharashtra state, the southern districts of Sangli, Satara, and Solapur (the three Ss) are the areas with the highest incidence of HIV/AIDS. We have evaluated the incidence of maternal to child transmission (MTCT) of HIV-1 infection in Belgaum District which is more than 500 kilometers distance by road from the campus in greater Bangalore (Karnataka State). We have obtained the prenatal CD4 counts of HIV infected pregnant mothers. We have also screened the HIV infected children in two orphanages (rehabilitation centres for HIV infected children) in Belgaum District. The clinical conditions of these infected children were assessed for their CD4 counts, anti-retroviral therapy (ART) intake status, outpatient illnesses and body composition. We have observed that there is an influence of the age factor on the CD4 counts of the HIV infected children. Further, in view of the role of our recently found involvement of sulfatide, 3-O- galactosylceramide, in inhibition of HIV-1 replication and enhancement of hematopoiesis which is otherwise inhibited due to such infection, we have discussed the possible role of sulfatides that biologically occur in the fetal adnexa (placentatrophoblasts /amnion/chorion-umbilical cord), in containing HIV infection as a potential safer alternative to the ART regimens currently approved to be clinically practiced. Lastly, we have discussed the complementary and alternative medicine (CAM) therapies such as evidence based yoga and ayurveda as add-on to ART in potential elimination of MTCT of HIV infection. Out of a total of 150 children delivered by HIV infected mothers, 13 children were found to be positive as determined by the dried blood smear (DBS) for virological testing

    Despite the biomedical potential to eliminate vertical HIV transmission, drug adherence to short regimens is often sub-optimal. To inform future programmes, we reviewed evidence on the factors influencing maternal and infant drug adherence to preventing MTCT drug regimens at delivery in sub-Saharan Africa. A literature review yielding 14 studies on adherence to drug regimes among HIV-positive pregnant women and mothers in sub-Saharan Africa was conducted. Rates of maternal adherence to preventive drug regimens at time of delivery varied widely across sites between 35 and 93.5%. Factors most commonly associated with low adherence to antiretroviral therapy (ARV) prophylaxis for preventing MTCT at the health system level include giving birth at home, quality and timing of HIV testing and counselling, and late distribution of nevirapine (NVP). Socio-demographic and demand-side factors include fear of stigma, lack of male involvement, fear of partner's reaction to disclosure, few antenatal (ANC) visits, young age and lack of education. With the implementation of the newly published WHO guidelines recommending triple-drug ARV regimen during pregnancy and breastfeeding for all women with HIV, it is important that women are able to adhere to recommended drug regimens. Service improvements should include clear and timely communication with women about the benefits of combined regimens and greater emphasis on patient confidentiality. Efforts must be made to help women overcome barriers that reduce adherence, such as financial logistical challenges, social stigma and women's fear of violence.

    HIV/AIDS impacts significantly on pregnant women and on children in Ethiopia. This impact has a multiplier effect on household economies and on productivity losses, and is expected to vary across rural and urban settings. Applying the human capital approach to data collected from 131 respondents, this study estimated productivity losses per HIV-positive pregnant woman-infant pair across urban and rural health facilities in Ethiopia, which in turn were used to estimate the national productivity loss. The study found that the annual productivity loss per woman-infant pair was Ethiopian birr (ETB) 7,433 or United States dollar (US$) 378 and ETB 625 (US$ 32) in urban and rural settings, respectively. The mean patient days lost per year due to inpatient admission at hospitals/health centres was 11 in urban and 22 in rural health facilities. On average, urban home care-givers spent 20 (SD = 21) days annually providing home care services, while their rural counterparts spent 23 days (SD = 26). The productivity loss accounted for 16% and 7% of household income in urban and rural settings, respectively. These high and varying productivity losses require preventive interventions that are appropriate to each setting to ensure the welfare of women and children in Ethiopia.

    Hispanic Americans consistently exhibit an intergenerational increase in the prevalence of many noncommunicable chronic physical and mental disorders. We review and synthesize evidence suggesting that a constellation of prenatal and postnatal factors may play crucial roles in explaining this trend. We draw from relevant literature across several disciplines, including epidemiology, anthropology, psychology, medicine (obstetrics, neonatology), and developmental biology. Our resulting model is based on evidence that among women, the process of postmigration cultural adjustment (i.e., acculturation) is associated, during pregnancy and after delivery, with psychological and behavioral states that can affect offspring development in ways that may alter susceptibility to noncommunicable chronic disease risk in subsequent-generation Hispanic Americans. We propose one integrated process model that specifies the biological, behavioral, psychological, and sociocultural pathways by which maternal acculturation may influence the child's long-term health. We synthesize evidence from previous studies to describe how acculturation among Hispanic American mothers is associated with alterations to the same biobehavioral systems known to participate in the processes of prenatal and postnatal developmental programming of disease risk. In this manner, we focus on the concepts of biological and cultural mother-to-child transmission across the prenatal and postnatal life phases. We critique and draw from previous hypotheses that have sought to explain this phenomenon (of declining health across generations). We offer recommendations for examining the transgenerational effects of acculturation. A life course model with a greater focus on maternal health and well-being may be key to understanding transgenerational epidemiological trends in minority populations, and interventions that promote women's wellness may contribute to the elimination or reduction of health disparities.

    Great efforts have been made in the last few years in order to implement the prevention of mother-to-child transmission (PMTCT) program in Equatorial Guinea (GQ). The aim of this study was to evaluate the rates of mother-to-child HIV transmission based on an HIV early infant diagnosis (EID) program. A prospective observational study was performed in the Regional Hospital of Bata and Primary Health Care Centre Maria Rafols, Bata, GQ. Epidemiological, clinical, and microbiological characteristics of HIV-1-infected mothers and their exposed infants were recorded. Dried blood spots (DBS) for HIV-1 EID were collected from November 2012 to December 2013. HIV-1 genome was detected using Siemens VERSANT HIV-1 RNA 1.0 kPCR assay. Sixty nine pairs of women and infants were included. Sixty women (88.2%) had WHO clinical stage 1. Forty seven women (69.2%) were on antiretroviral treatment during pregnancy. Forty five infants (66.1%) received postnatal antiretroviral prophylaxis. Age at first DBS analysis was 2.4 months (IQR 1.2-4.9). One infant died before a HIV-1 diagnosis could be ruled out. Two infants were HIV-1 infected and started HAART before any symptoms were observed. The rate of HIV-1 transmission observed was 2.9% (95%CI 0.2-10.5). The PMTCT rate was evaluated for the first time in GQ based on EID. EID is the key for early initiation of antiretroviral therapy and to reduce the mortality associated with HIV infection.

    Full Text Available Abstract Background The implementation of collaborative TB/HIV activities may help to mitigate the impact of the dual epidemic on patients and communities. Such implementation requires integrated interventions across facilities and levels of government, and with communities. Engaging Community Care Workers (CCWs in the delivery of integrated TB/HIV services may enhance universal coverage and treatment outcomes, and address human resource needs in sub-Saharan Africa. Methods Using pre-intervention research in Sisonke district, KwaZulu-Natal, South Africa as a case study, we report on three study objectives: (1 to determine the extent of the engagement of NGOs and CCWs in the implementation of collaborative TB/HIV including PMTCT; (2 to identify constraints related to provision of TB/HIV/PMTCT integrated care at community level; and (3 to explore ways of enhancing the engagement of CCWs to provide integrated TB/HIV/PMTCT services. Our mixed method study included facility and NGO audits, a household survey (n = 3867, 33 key informant interviews with provincial, district, facility, and NGO managers, and six CCW and patient focus group discussions. Results Most contracted NGOs were providing TB or HIV support and care with little support for PMTCT. Only 11% of facilities’ TB and HIV patients needing care and support at the community level were receiving support from CCWs. Only 2% of pregnant women reported being counseled by CCWs on infant feeding options and HIV testing. Most facilities (83% did not have any structural linkage with NGOs. Major constraints identified were system-related: structural, organizational and managerial constraints; inadequate CCW training and supervision; limited scope of CCW practice; inadequate funding; and inconsistency in supplies and equipment. Individual and community factors, such as lack of disclosure, stigma related to HIV, and cultural beliefs were also identified as constraints. Conclusions NGO

    One of the fundamental challenges to implementing successful prevention of mother-to-child transmission (PMTCT) programs in Nigeria is the uptake of PMTCT services at health facilities. Several issues usually discourage many pregnant women from receiving antenatal care services at designated health facilities within their communities. The CRS Nigeria PMTCT Project funded by the Global Fund in its Round 9 Phase 1 in Nigeria, sought to increase demand for HIV counseling and testing services for pregnant women at 25 supported primary health centers (PHCs) in Kaduna State, North-West Nigeria by integrating traditional birth attendants (TBAs) across the communities where the PHCs were located into the project. Community dialogues were held with the TBAs, community leaders and women groups. These dialogues focused on modes of mother to child transmission of HIV and the need for TBAs to refer their clients to PHCs for testing. Subsequently, data on number of pregnant women who were counseled, tested and received results was collected on a monthly basis from the 25 facilities using the national HIV/AIDS tools. Prior to this integration, the average number of pregnant women that were counseled, tested and received results was 200 pregnant women across all the 25 health facilities monthly. After the integration of TBAs into the program, the number of pregnant women that were counseled, tested and received results kept increasing month after month up to an average of 1500 pregnant women per month across the 25 health facilities. TBAs can thus play a key role in improving service uptake and utilization for pregnant women at primary health centers in the community - especially in the context of HIV/AIDS. They thus need to be integrated, rather than alienated, from primary healthcare service delivery.

  14. Estimating the timing of mother-to-child transmission of the human immunodeficiency virus type 1 using a viral molecular evolution model.

    Directory of Open Access Journals (Sweden)

    Antoine Chaillon

    Full Text Available Mother-to-child transmission (MTCT is responsible for most pediatric HIV-1 infections worldwide. It can occur during pregnancy, labor, or breastfeeding. Numerous studies have used coalescent and molecular clock methods to understand the epidemic history of HIV-1, but the timing of vertical transmission has not been studied using these methods. Taking advantage of the constant accumulation of HIV genetic variation over time and using longitudinally sampled viral sequences, we used a coalescent approach to investigate the timing of MTCT.Six-hundred and twenty-two clonal env sequences from the RNA and DNA viral population were longitudinally sampled from nine HIV-1 infected mother-and-child pairs [range: 277-1034 days]. For each transmission pair, timing of MTCT was determined using a coalescent-based model within a Bayesian statistical framework. Results were compared with available estimates of MTCT timing obtained with the classic biomedical approach based on serial HIV DNA detection by PCR assays.Four children were infected during pregnancy, whereas the remaining five children were infected at time of delivery. For eight out of nine pairs, results were consistent with the transmission periods assessed by standard PCR-based assay. The discordance in the remaining case was likely confused by co-infection, with simultaneous introduction of multiple maternal viral variants at the time of delivery.The study provided the opportunity to validate the Bayesian coalescent approach that determines the timing of MTCT of HIV-1. It illustrates the power of population genetics approaches to reliably estimate the timing of transmission events and deepens our knowledge about the dynamics of viral evolution in HIV-infected children, accounting for the complexity of multiple transmission events.

    This study was conducted to identify reasons for a high and progressive loss to follow-up among HIV-positive mothers within a prevention-of-mother-to-child HIV transmission (PMTCT) program in a rural district hospital in Malawi. Three focus group discussions were conducted among a total of 25 antenatal and post-natal mothers as well as nurse midwives (median age 39 years, range 22-55 years). The main reasons for loss to follow-up included: (1) not being prepared for HIV testing and its implications before the antenatal clinic (ANC) visit; (2) fear of stigma, discrimination, household conflict and even divorce on disclosure of HIV status; (3) lack of support from husbands who do not want to undergo HIV testing; (4) the feeling that one is obliged to rely on artificial feeding, which is associated with social and cultural taboos; (5) long waiting times at the ANC; and (6) inability to afford transport costs related to the long distances to the hospital. This study reveals a number of community- and provider-related operational and cultural barriers hindering the overall acceptability of PMTCT that need to be addressed urgently. Mothers attending antenatal services need to be better informed and supported, at both community and health-provider level.

    Success in prevention of mother-to-child transmission (PMTCT) raises the prospect of eliminating pediatric HIV infection. To achieve global elimination, however, strategies are needed to strengthen PMTCT interventions. This study aimed to determine PMTCT outcomes and identify challenges facing its successful implementation in a rural setting in Kenya. A retrospective cohort design was used. Routine demographic and clinical data for infants and mothers enrolling for PMTCT care at a rural hospital in Kenya were analysed. Cox and logistic regression were used to determine factors associated with retention and vertical transmission respectively. Between 2006 and 2012, 1338 infants were enrolled and followed up for PMTCT care with earlier age of enrollment and improved retention observed over time. Mother to child transmission of HIV declined from 19.4 % in 2006 to 8.9 % in 2012 (non-parametric test for trend p = 0.024). From 2009 to 2012, enrolling for care after 6 months of age, adjusted Odds Ratio [aOR]: 23.3 [95 % confidence interval (CI): 8.3-65.4], presence of malnutrition ([aOR]: 2.3 [95 % CI: 1.1-5.2]) and lack of maternal use of highly active antiretroviral therapy (HAART) (aOR: 6.5 [95 % CI: 1.4-29.4]) was associated with increased risk of HIV infection. Infant's older age at enrollment, malnutrition and maternal HAART status, were also associated with drop out from care. Infants who were not actively followed up were more likely to drop out from care (adjusted Hazard Ratio: 6.6 [95 % CI: 2.9-14.6]). We report a temporal increase in the proportion of infants enrolling for PMTCT care before 3 months of age, improved retention in PMTCT and a significant reduction in the proportion of infants enrolled who became HIV-infected, emphasizing the benefits of PMTCT. A simple set of risk factors at enrollment can identify mother-infant pairs most at risk of infection or drop out for targeted intervention.

    Mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV-1) as described for women with an established infection is, in most cases, associated with the transmission of few maternal variants. This study analysed virus variability in four cases of maternal primary infection occurring during pregnancy and/or breastfeeding. Estimated time of seroconversion was at 4 months of pregnancy for one woman (early seroconversion) and during the last months of pregnancy and/or breastfeeding for the remaining three (late seroconversion). The C2V3 envelope region was analysed in samples of mother-child pairs by molecular cloning and sequencing. Comparisons of nucleotide and amino acid sequences as well as phylogenetic analysis were performed. The results showed low variability in the virus population of both mother and child. Maximum-likelihood analysis showed that, in the early pregnancy seroconversion case, a minor viral variant with further evolution in the child was transmitted, which could indicate a selection event in MTCT or a stochastic event, whereas in the late seroconversion cases, the mother's and child's sequences were intermingled, which is compatible with the transmission of multiple viral variants from the mother's major population. These results could be explained by the less pronounced selective pressure exerted by the immune system in the early stages of the mother's infection, which could play a role in MTCT of HIV-1.

    Asialoglycoprotein receptor expression on hepatocytes has been associated with endocytosis, binding and uptake of hepatitis B virus. The role of asialoglycoprotein receptor in hepatitis B virus vertical transmission and its expression on placenta has not yet been studied. Thirty-four HBsAg+ve and 13 healthy pregnant mothers along with their newborns were enrolled. The former were categorized into transmitting and non-transmitting mothers based on their newborns being hepatitis B surface antigen and hepatitis B virus DNA positive. Expression of asialoglycoprotein receptor and hepatitis B surface antigen in placenta and isoform of asialoglycoprotein receptor on dendritic cell in peripheral and cord blood dendritic cells were analysed using flowcytometry, immune histochemistry, immune florescence and qRT-PCR. Twelve HBsAg+ve mothers transmitted hepatitis B virus to their newborns whereas the rest (n = 22) did not. Hepatitis B virus-transmitting mothers showed increased expression of asialoglycoprotein receptor in trophoblasts of placenta. Immunofluorescence microscopy revealed colocalization of hepatitis B surface antigen and asialoglycoprotein receptor in placenta as well as in DCs of transmitting mothers. There was no significant difference in the expression of asialoglycoprotein receptor on peripheral blood mononuclear cells or chord blood mononuclear cells between the 2 groups. However, hepatitis B virus-transmitting mothers and their HBsAg+ve newborns showed increased mRNA levels of isoform of asialoglycoprotein receptor on dendritic cell in peripheral blood mononuclear cells. Hepatitis B virus-transmitting mothers and their HBsAg+ve newborns showed an increased expression of isoform of asialoglycoprotein receptor on dendritic cell on circulating dendritic cells compared to hepatitis B virus non-transmitting mothers and their negative newborns. This study revealed that increased expression of asialoglycoprotein receptor in placenta and colocalization with

    This review was carried out to provide a comprehensive overview of efforts toward elimination of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) with respect to progress, challenges, and recommendations in 21 sub-Saharan African priority countries. We reviewed literature published from 2011 to April 2015 using 3 databases; PubMed, Scopus, and Web of Science, as well as the 2014 Global Plan Progress Report. A total of 39 studies were included. Between 2009 and 2013, there was a 43% reduction in new HIV infections, the final MTCT rate was reduced from 28% to 18%, and antiretroviral therapy (ART) coverage increased from 11% to 24%. Challenges included poor adherence to antiretroviral therapy, poor linkage between mother-child pairs and post-natal healthcare services low early infant diagnosis coverage, low pediatric ART coverage, and high unmet needs for contraceptive services. Future recommendations include identification of key barriers, health system strengthening, strengthening community involvement, and international collaboration. There has been significant progress toward eliminating MTCT of HIV, but more effort is still needed. Copyright © 2015 King Saud Bin Abdulaziz University for Health Sciences.

    Role of host factors in transmission of human papillomavirus (HPV)-infection from mother to her offspring is not known. Our aim was to study whether human leukocyte antigen (HLA)-G allele concordance among the mother-child pairs could facilitate vertical transmission of HPV, because HLA-G may contribute to immune tolerance in pregnancy. Altogether, 310 mother-child pairs were included from the Finnish Family HPV study. Overall, nine different HLA-G alleles were identified. The HLA-G genotype concordance of G ∗ 01:01:01/01:04:01 increased the risk of high risk (HR)-HPV genotype positivity in cord blood and infant's oral mucosa. The mother-child concordance of G ∗ 01:01:02/01:01:02 increased the risk of oral HPV positivity with HR-HPV genotypes both in the mother and offspring; OR 2.45 (95%CI 1.24-4.85). Discordant HLA-G allele for G ∗ 01:04:01 and for G ∗ 01:06 was significantly associated with infant's oral low risk (LR)-HPV at birth, OR 3.07 (95%CI 1.01-9.36) and OR 5.19 (95%CI 1.22-22.03), respectively. HLA-G had no association with HPV genotype-specific concordance between the mother and child at birth nor influence on perinatal HPV status of the child. Taken together, our results show that HLA-G molecules have a role in predicting the newborn's likelihood for oral HPV infection at birth.

    Full Text Available OBJECTIVE: To assess the feasibility of HIV rapid testing for pregnant women at maternity hospital admission and of subsequent interventions to reduce perinatal HIV transmission. METHODS: Study based on a convenience sample of women unaware of their HIV serostatus when they were admitted to delivery in public maternity hospitals in Rio de Janeiro and Porto Alegre, Brazil, between March 2000 and April 2002. Women were counseled and tested using the Determine HIV1/2 Rapid Test. HIV infection was confirmed using the Brazilian algorithm for HIV infection diagnosis. In utero transmission of HIV was determined using HIV-DNA-PCR. There were performed descriptive analyses of sociodemographic data, number of previous pregnancies and abortions, number of prenatal care visits, timing of HIV testing, HIV rapid test result, neonatal and mother-to-child transmission interventions, by city studied. RESULTS: HIV prevalence in women was 6.5% (N=1,439 in Porto Alegre and 1.3% (N=3.778 in Rio de Janeiro. In Porto Alegre most of women were tested during labor (88.7%, while in Rio de Janeiro most were tested in the postpartum (67.5%. One hundred and forty-four infants were born to 143 HIV-infected women. All newborns but one in each city received at least prophylaxis with oral zidovudine. It was possible to completely avoid newborn exposure to breast milk in 96.8% and 51.1% of the cases in Porto Alegre and Rio de Janeiro, respectively. Injectable intravenous zidovudine was administered during labor to 68.8% and 27.7% newborns in Porto Alegre and Rio de Janeiro, respectively. Among those from whom blood samples were collected within 48 hours of birth, in utero transmission of HIV was confirmed in 4 cases in Rio de Janeiro (4/47 and 6 cases in Porto Alegre (6/79. CONCLUSIONS: The strategy proved feasible in maternity hospitals in Rio de Janeiro and Porto Alegre. Efforts must be taken to maximize HIV testing during labor. There is a need of strong social support to

    Full Text Available About 69% of people living with HIV globally and over 90% of the children who acquired HIV infection are in Sub-Saharan Africa. Despite this, promising results have been observed, especially over the last decade – for example, a 25% decline in new HIV infections as compared to 2001 and a 38% decline in the number of children newly infected by HIV in 2012 as compared to 2009. However, the Global Plan and the Global Fast-Track Commitments of eliminating new HIV infections among children require addressing impediments to service expansion. In this regard, this paper attempts to draw attention to the extent to which disparities across income in using antenatal care (ANC services may constrain the prevention of mother-to-child transmission (PMTCT service expansion in Sub-Saharan Africa. The analysis is based on ANC service coverage data from Demographic and Health Surveys conducted between 2008 and 2015 in 31 Sub-Saharan African countries; and PMTCT coverage data from UNAIDS datasets released in 2016. Our analysis found that women in the highest wealth quintile are about three times more likely to frequently use ANC services (at least four visits as compared to those in the lowest wealth quintile (95%CI: 1.7-5.7, P<0.0001. A regression analysis shows that one-quarter of the PMTCT service coverage can be explained by the disparity in ANC use associated with income; and the higher the disparity in ANC use, the lower the PMTCT service (P<0.05. The findings suggest that achieving the ambitious plan of zero new HIV infections among children while keeping their mothers alive will require on-going PMTCT/ANC service integration and ensuring that programs reach women who are most in need; specifically those in the poorest income categories.

    Full Text Available One of the fundamental challenges to implementing successful prevention of mother-tochild transmission (PMTCT programs in Nigeria is the uptake of PMTCT services at health facilities. Several issues usually discourage many pregnant women from receiving antenatal care services at designated health facilities within their communities. The CRS Nigeria PMTCT Project funded by the Global Fund in its Round 9 Phase 1 in Nigeria, sought to increase demand for HIV counseling and testing services for pregnant women at 25 supported primary health centers (PHCs in Kaduna State, North-West Nigeria by integrating traditional birth attendants (TBAs across the communities where the PHCs were located into the project. Community dialogues were held with the TBAs, community leaders and women groups. These dialogues focused on modes of mother to child transmission of HIV and the need for TBAs to refer their clients to PHCs for testing. Subsequently, data on number of pregnant women who were counseled, tested and received results was collected on a monthly basis from the 25 facilities using the national HIV/AIDS tools. Prior to this integration, the average number of pregnant women that were counseled, tested and received results was 200 pregnant women across all the 25 health facilities monthly. After the integration of TBAs into the program, the number of pregnant women that were counseled, tested and received results kept increasing month after month up to an average of 1500 pregnant women per month across the 25 health facilities. TBAs can thus play a key role in improving service uptake and utilization for pregnant women at primary health centers in the community – especially in the context of HIV/AIDS. They thus need to be integrated, rather than alienated, from primary healthcare service delivery.

    Although substantiated by little evidence, concerns about zidovudine-related anaemia in pregnancy have influenced antiretroviral (ARV) regimen choice for preventing mother-to-child transmission of HIV-1, especially in settings where anaemia is common. Eligible HIV-infected pregnant women in Burkina Faso, Kenya and South Africa were followed from 28 weeks of pregnancy until 12-24 months after delivery (n = 1070). Women with a CD4 count of 200-500 cells/mm(3) and gestational age 28-36 weeks were randomly assigned to zidovudine-containing triple-ARV prophylaxis continued during breastfeeding up to 6-months, or to zidovudine during pregnancy plus single-dose nevirapine (sd-NVP) at labour. Additionally, two cohorts were established, women with CD4 counts: 500 cells/mm(3) received zidovudine during pregnancy plus sd-NVP at labour. Mild (haemoglobin 8.0-10.9 g/dl) and severe anaemia (haemoglobin anaemia occurred subsequently in 194 (18.1%) women, mostly in those with low baseline haemoglobin, lowest socio-economic category, advanced HIV disease, prolonged breastfeeding (≥ 6 months) and shorter ARV exposure. Severe anaemia incidence was similar in the randomized arms (equivalence P-value = 0.32). After 1-2 months of ARV's, severe anaemia was significantly reduced in all groups, though remained highest in the low CD4 cohort. Severe anaemia occurs at a similar rate in women receiving longer triple zidovudine-containing regimens or shorter prophylaxis. Pregnant women with pre-existing anaemia and advanced HIV disease require close monitoring. ISRCTN71468401.

    TODOS: Estudo ecológico tendo como unidade de análise as áreas de abrangência de unidades básicas de saúde em Porto Alegre, RS, em 2003. Foram utilizados Sistema de Informações Geográficas e ferramentas de análise espacial para calcular indicadores de cobertura da atenção básica à saúde, condições socioeconômicas e prevalência de nascidos vivos expostos ao HIV durante a gravidez e perinatal. Os dados analisados foram obtidos em sistemas de informação nacionais. A associação entre os diferentes indicadores foi avaliada por meio de teste não-paramétrico de Spearman. RESULTADOS: Observou-se associação entre infecção pelo HIV em gestantes com taxas de natalidade (r=0,22, p<0,01 e falta de assistência pré-natal (r=0,15, p<0,05. As maiores taxas de infecção por HIV em gestantes foram verificadas em áreas com piores condições socioeconômicas e dificuldades de acesso a serviços de saúde (r=0,28, p<0,01. No entanto, a relação observada entre a maior freqüência de assistência pré-natal entre gestantes HIV positivas e maior cobertura vacinal nas áreas (r=0,35, p<0,01 indica a capacidade de detecção precoce da infecção pelo HIV em áreas com melhores serviços de atenção básica. CONCLUSÕES: A pobreza urbana representa um forte condicionante da transmissão vertical do HIV mas a atuação de serviços de vigilância em saúde articulados com a atenção básica podem vencer essa tendência.

    Objective: To evaluate the cost effectiveness of nationwide prevention of mother to child transmission (PMTCT) strategy for hepatitis B, and estimate the willing to pay and budget impacts on the PMTCT. Methods: The decision analytic Markov model for the PMTCT was constructed and a birth cohort of Chinese infants born in 2013 was used to calculate the cost-effectiveness of the PMTCT among them compared with those receiving no intervention. The parameters in the model were obtained from literatures of national surveys or Meta-analysis. The costs, cases of HBV-related diseases and quality-adjusted life-years (QALYs) were obtained from the societal and payer perspectives, respectively. The incremental cost-effectiveness ratio (ICER) was used as measures of strategy optimization. One-way and probability sensitivity analysis were performed to explore the uncertainty of the primary results. In addition, cost-effectiveness acceptability curve and cost-effectiveness affordability curves were drawn to illustrate the cost effectiveness threshold and financial budget of the PMTCT strategy. Results: The lifetime cost for PMTCT strategy was 4 063.5 yuan (RMB) per carrier, which was 37 829.7 yuan (RMB) lower compared with those receiving no intervention. Due to the strategy, a total of 24.516 1 QALYs per person would be gained, which was higher than that in those receiving no intervention. From societal perspective, the ICER was -59 136.6 yuan (RMB) per additional QALYs gained, indicating that the PMTCT is cost effective. The results were reliable indicated by one-way, multi-way and probability sensitivity analyses. By the CEAC, the willing to pay was much lower than the cost-effectiveness threshold. From the affordability curve of the PMTCT strategy, the annual budget ranged from 590.4 million yuan (RMB) to 688.8 million yuan (RMB), which was lower than the financial ability. Based on the results of cost-effectiveness affordability curves, the higher annual budget was determined

    Background Thailand has made progress in reducing perinatal HIV transmission rates to levels that meet the World Health Organization targets for so-called “elimination” (HIV/AIDS Treatment Prevention Working Group issued a new version of its National Prevention of MTCT guidelines in March 2017 aimed to reduce MTCT rate to HIV is diagnosed for ART naïve HIV-infected pregnant women. An alternative regimen is TDF or zidovudine (AZT) plus 3TC/FTC plus lopinavir/ritonavir (LPV/r) for HIV-infected pregnant women suspected resistant to non-nucleoside reverse transcriptase inhibitors. Treatment should be started immediately irrespective of gestational age and continued after delivery for life. Raltegravir is recommended in addition to the ART regimen for HIV-infected pregnant women who present late (gestational age (GA) ≥32 weeks) or those who have a viral load (VL) >1000 copies/mL at GA ≥32 weeks. HIV-infected pregnant women who conceive while receiving ART should continue their treatment regimen during pregnancy. HIV-infected pregnant women who present in labor and are not receiving ART should receive single-dose nevirapine immediately along with oral AZT, and continue ART for life. Infants born to HIV-infected mothers are categorized as high or standard risk for MTCT. High MTCT risk is defined as an infant whose mother has a viral load (VL) > 50 copies/mL at GA > 36 weeks or has received ART HIV-exposed infants. PMID:29861798

    Point-of-care (POC) testing has been shown to help improve healthcare access in resource-limited settings. However, there is paucity of evidence on accessibility of POC testing for prevention of mother-to-child transmission (PMTCT) in resource-limited settings. We propose to conduct a systematic scoping review to map the evidence on POC testing services for PMTCT. A scoping review framework, proposed by Arksey and O'Malley, will guide the study. A comprehensive literature search will be performed in the following electronic databases: PubMed, Science Direct, Cochrane Central, Google Scholar and databases within EBSCOhost (Medline and CINAHL). The primary research articles published in peer-reviewed journals and grey articles addressing our question will be included. One reviewer will conduct title screening and the results will be exported to endnote library. Two independent reviewers will perform abstract, then full article screening in parallel. The same process shall be employed to extract data from eligible studies. Data analysis will involve a narrative summary of included studies and thematic content analysis aided by NVIVO software V.11. The mixed methods assessment tool will be used to assess the quality of studies that will be included. Ethical approval is not applicable to this study. The study findings will be disseminated through publication in a peer-reviewed journal and presentations at conferences related to syphilis, HIV, PMTCT, bacterial infections and POC diagnostics.

    The prevalence of human immunodeficiency virus (HIV)-infected pregnant women in Equatorial Guinea (EG) has been reported as 7.3%. In 2008 an updated version of the PMTCT protocol was accepted according to the current WHO guidelines. The aim of this study was to describe the characteristics and outcome of children exposed to HIV after the introduction of the protocol. A retrospective review was conducted on the clinical characteristics of the infants born to HIV-infected mothers in the Hospital Regional de Bata and Primary Health Care Centre Maria Rafols in Bata (EG) between June 2008 and November 2011. The diagnosis of HIV infection in children was based on rapid serology tests. A total of 103 children were included, of which 47 were males. Fifty three patients (51%) completed the follow-up (51%). Fourteen children (26%) were diagnosed with HIV infection (11 presumptive diagnosis, 3 due to persistence of antibodies at 18 months). Six children (12%) died before a definitive diagnosis. Just over than half (52%) of mothers received antiretroviral therapy (ART) during pregnancy. The transmission rate in children whose mothers received ART was 16% (3/19), compared with 43% (10/23) in children whose mothers did not receive it. Only one child was infected (8%) when the mother received ART, and child received postnatal prophylaxis. The PMTCT protocol compliance was still very low. Antiretroviral therapy in pregnant women decreased the rate of vertical transmission, but the rate still remains very high. Many children were lost to follow-up. Strategies to prevent loss to follow-up and methods for earlier virological diagnostic are needed. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    This paper reports on factors influencing the decision of mothers regarding the type of feeding method for their babies in a rural setting in Cameroon. The aim of the study was to ascertain the proportion of mothers choosing the different methods of feeding, to determine the various factors influencing their choices, and to ascertain the relationships of these factors to their respective choices. Questionnaires were used on 108 HIV-positive mothers who had delivered babies and who were administered nevirapine at least 3 months prior to the study. A focus group discussion with mothers also took place. Findings were that more mothers (84%) chose breastfeeding than artificial feeding (16%), while a minority (4%) selected mixed feeding. Factors found to militate against artificial feeding were cost (69%), stigma (64%), family pressure (44%), inconvenience in preparation/administration (38%), prior education from health workers (23%), and loss of special attention from family (8%). On the other hand, advice of health worker (44%), ill health (19.5%), free milk (12.5%),job pressure (12.5%) and loss of beauty (12.5%) were found to militate against breastfeeding. A direct relationship was also found between age, educational level, income size, marital status and choice of feeding. Policies targeting stigma reduction and socio-cultural factors affecting the choice of feeding are needed to optimise uptake of the less risky methods of feeding which could in turn contribute to a reduction in transmission.

    Full Text Available In 2012, the World Health Organization (WHO amended their 2010 guidelines for women receiving limited duration, triple-antiretroviral drug regimens during pregnancy and breastfeeding for prevention of mother-to-child transmission of HIV (tARV-PMTCT (Option B to include the option to continue lifelong combination antiretroviral therapy (cART (Option B+. We evaluated clinical and CD4 outcomes in women who had received antiretrovirals for prevention of mother-to-child transmission and then discontinued antiretrovirals 6-months postpartum.The Kisumu Breastfeeding Study, 2003-2009, was a prospective, non-randomized, open-label clinical trial of tARV-PMTCT in ARV-naïve, Kenyan women. Women received tARV-PMTCT from 34 weeks' gestation until 6-months postpartum when women were instructed to discontinue breastfeeding. Women with CD4 count (CD4 <250cells/mm3 or WHO stage III/IV prior to 6-months postpartum continued cART indefinitely. We estimated the change in CD4 after discontinuing tARV-PMTCT and the adjusted relative risk [aRR] for factors associated with declines in maternal CD4. We compared maternal and infant outcomes following weaning-when tARV-PMTCT discontinued-by maternal ARV status through 24-months postpartum. Compared with women who continued cART, discontinuing antiretrovirals was associated with infant HIV transmission and death (10.1% vs. 2.4%; P = 0.03. Among women who discontinued antiretrovirals, CD4<500 cells/mm3 at either initiation (21.8% vs. 1.5%; P = 0.002; aRR: 9.8; 95%-confidence interval [CI]: 2.4-40.6 or discontinuation (36.9% vs. 8.3%; P<0.0001; aRR: 4.4; 95%-CI: 1.9-5.0 were each associated with increased risk of women requiring cART for their own health within 6 months after discontinuing.Considering the serious health risks to the woman's infant and the brief reprieve from cART gained by stopping, every country should evaluate the need for and feasibility to implement WHO Option B+ for PMTCT.

    Full Text Available Hepatitis B virus (HBV infection remains a serious public health problem worldwide. Mother-to-child transmission (MTCT of HBV is the major mode of transmission in HBV-endemic areas, including China, where little is known about pregnant women's knowledge of and attitudes towards HBV infection and MTCT.A cross-sectional survey, conducted in pregnant women in Guangdong Province, China, measured HBV knowledge and attitudes using a questionnaire, at one tertiary and two rural hospitals.The total response rate was 94.5% (737/780. Of the 11 knowledge questions, the mean score was 6.73 ± 3.04 (mean ± SD. Most pertinent to preventing MTCT, 53.3% of the respondents did not know that HBV can be transmitted through unprotected sexual intercourse and nearly 20% did not know that HBV can be transmitted from mother to infant. The results of the four attitude questions was better with 83% and 85% being willing to be screened for HBV and let their baby receive HBV vaccine and HBIg, respectively. However, only 16.5% of respondents agreed that they would be willing to take drugs that are known not to harm the fetus to prevent MTCT of HBV. In multivariable analysis, higher education level was associated with better knowledge and attitude scores.Knowledge about HBV among pregnant women was poor and needs to be improved to prevent MTCT of HBV. Health education needs to be directed towards pregnant mothers, particularly less educated mothers, in high HBV endemicity settings.

    Maternal syphilis is a health threat to both the pregnant women and the children. This study aimed to delineate the longitudinal trend of maternal syphilis and burden of associated adverse pregnant outcomes (APOs) in Shanghai from 2001 to 2015; and to evaluate the effects of preventing mother-to-child transmission (PMTCT) of syphilis in Shanghai with regard to service coverage and APOs averted. PMTCT program of syphilis has been implemented since 2001. Municipal and national PMTCT surveillance data were used in analysis. By using WHO estimation model, the burden of associated APOs and APOs averted were estimated. The differences in access to antenatal care and PMTCT services between resident and non-resident pregnant women were analyzed. The prevalence of seropositivity for maternal syphilis in Shanghai ranged from 0.20% to 0.38% during 2001-2015. The treatment rate varied from 69.8% to 96.8% and remained 83.6% in 2015. Under the PMTCT program, 2163 APOs had been averted during the 15-year period, including 852(39.4%) early fetal loss/stillbirth, 356(16.4%) neonatal death, 190(8.8%) prematurity or low birth weight, and 765(35.4%) clinical evidence of congenital syphilis. Compared with the residents, the non-resident pregnant women had a higher prevalence of syphilis (1.2‰ vs. 2.5‰) and contributed to 81.7% of the syphilis associated APOs in 2015. Screening of maternal syphilis has reached a full coverage both in residents and non-residents. Large numbers of APOs has been averted attributing to the PMTCT program. More attentions should be paid to those vulnerable non-resident pregnant women and tailored interventions including health education, PMTCT promotion and point of care should be given to maximize the effects of PMTCT in Shanghai.

    The role of gender in prevention of mother-to-child transmission (PMTCT) participation under Option B+ has not been adequately studied, but it is critical for reducing losses to follow-up. This study used qualitative methods to examine the interplay of gender and individual, interpersonal, health system, and community factors that contribute to PMTCT participation in Malawi and Uganda. We conducted in-depth interviews with women in PMTCT, women lost to follow-up, government health workers, and stakeholders at organizations supporting PMTCT as well as focus group discussions with men. We analyzed the data using thematic content analysis. We found many similarities in key themes across respondent groups and between the two countries. The main facilitators of PMTCT participation were knowledge of the health benefits of ART, social support, and self-efficacy. The main barriers were fear of HIV disclosure and stigma and lack of social support, male involvement, self-efficacy, and agency. Under Option B+, women learn about their HIV status and start lifelong ART on the same day, before they have a chance to talk to their husbands or families. Respondents explained that very few husbands accompanied their wives to the clinic, because they felt it was a female space and were worried that others would think their wives were controlling them. Many respondents said women fear disclosing, because they fear HIV stigma as well as the risk of divorce and loss of economic support. If women do not disclose, it is difficult for them to participate in PMTCT in secret. If they do disclose, they must abide by their husbands' decisions about their PMTCT participation, and some husbands are unsupportive or actively discouraging. To improve PMTCT participation, Ministries of Health should use evidence-based strategies to address HIV stigma, challenges related to disclosure, insufficient social support and male involvement, and underlying gender inequality.

    Through cost-benefit analysis (CBA), cost-effectiveness analysis (CEA) and quantitative optimization analysis to understand the economic benefit and outcomes of strategy regarding preventing mother-to-child transmission (PMTCT) on hepatitis B virus. Based on the principle of Hepatitis B immunization decision analytic-Markov model, strategies on PMTCT and universal vaccination were compared. Related parameters of Shenzhen were introduced to the model, a birth cohort was set up as the study population in 2013. The net present value (NPV), benefit-cost ratio (BCR), incremental cost-effectiveness ratio (ICER) were calculated and the differences between CBA and CEA were compared. A decision tree was built as the decision analysis model for hepatitis B immunization. Three kinds of Markov models were used to simulate the outcomes after the implementation of vaccination program. The PMTCT strategy of Shenzhen showed a net-gain as 38 097.51 Yuan/per person in 2013, with BCR as 14.37. The universal vaccination strategy showed a net-gain as 37 083.03 Yuan/per person, with BCR as 12.07. Data showed that the PMTCT strategy was better than the universal vaccination one and would end with gaining more economic benefit. When comparing with the universal vaccination program, the PMTCT strategy would save 85 100.00 Yuan more on QALY gains for every person. The PMTCT strategy seemed more cost-effective compared with the one under universal vaccination program. In the CBA and CEA hepatitis B immunization programs, the immunization coverage rate and costs of hepatitis B related diseases were the most important influencing factors. Outcomes of joint-changes of all the parameters in CEA showed that PMTCT strategy was a more cost-effective. The PMTCT strategy gained more economic benefit and effects on health. However, the cost of PMTCT strategy was more than the universal vaccination program, thus it is important to pay attention to the process of PMTCT strategy and the universal

    The objective of this analysis was to identify points of disruption within the prevention of mother-to-child transmission (PMTCT) continuum from combination antiretroviral therapy (CART) initiation until delivery. To address this objective, the electronic medical records of all antiretroviral-naïve adult pregnant women who were initiating CART for PMTCT between January 2006 and February 2009 within the Academic Model Providing Access To Healthcare (AMPATH), western Kenya, were reviewed. Outcomes of interest were clinician-initiated change or stop in regimen, disengagement from programme (any, early, late) and self-reported medication adherence. Disengagement was categorized as early disengagement (any interval of greater than 30 days between visits but returning to care prior to delivery) or late disengagement (no visit within 30 days prior to the date of delivery). The association between covariates and the outcomes of interest were assessed using bivariate (Kruskal-Wallis test for continuous variables and the Chi-square test for categorical variables) and multivariate logistic regression analysis. A total of 4284 antiretroviral-naïve pregnant women initiated CART between January 2006 and February 2009. The majority of women (89%) reported taking all of their medication at every visit. There were 18 (0.4%) deaths reported. Clinicians discontinued CART in 10 patients (0.7%) while 1367 (31.9%) women disengaged from care. Of those disengaging, 404 (29.6%) disengaged early and 963 (70.4%) late. In the multivariate model, the odds of disengagement decreased with increasing age (odds ratio [OR] 0.982; confidence interval [CI] 0.966-0.998) and increasing gestational age at CART initiation (OR 0.925; CI 0.909-0.941). Women receiving care at a district hospital (OR 0.794; CI 0.644-0.980) or tuberculosis medication (OR 0.457; CI 0.202-0.935) were less likely to disengage. The odds of disengagement were higher in married women (OR 1.277; CI 1.034-1.584). The odds of early

    Full Text Available The role of the hepatitis B virus (HBV mutant G145R, with a single change in amino acid 145 of the surface protein, as a minor population remains unknown in mother-to-child transmission. The minor strain as well as the major strain of the G145R mutant were evaluated in three cohorts using a locked nucleic acid probe-based real-time PCR. The breakthrough cohort consisted of children who were born to HBV carrier mothers and became HBV carriers despite immnoprophylaxis (n = 25. The control cohort consisted of HBV carriers who had no history of receiving the hepatitis B vaccine, hepatitis B immunoglobulin or antiviral treatment (n = 126. The pregnant cohort comprised pregnant women with chronic HBV infection (n = 31. In the breakthrough cohort, 6 showed positive PCR results (major, 2; minor, 4. In the control cohort, 13 showed positive PCR results (major, 0; minor, 13. HBeAg-positive patients were prone to have the G145R mutant as a minor population. Deep sequencing was performed in a total of 32 children (PCR positive, n = 13; negative, n = 19. In the breakthrough cohort, the frequency of the G145R mutant ranged from 0.54% to 6.58%. In the control cohort, the frequency of the G145R mutant ranged from 0.42% to 4.1%. Of the 31 pregnant women, 4 showed positive PCR results (major, n = 0; minor, n = 4. All of the pregnant women were positive for HBeAg and showed a high viral load. Three babies born to 3 pregnant women with the G145R mutant were evaluated. After the completion of immunoprophylaxis, 2 infants became negative for HBsAg. The remaining infant became negative for HBsAg after the first dose of HB vaccine. G145R was detected in one-fourth of the children with immunoprophylaxis failure. However, the pre-existence of the G145R mutant as a minor population in pregnant women does not always cause breakthrough infection in infants.

    Objective: To establish the hepatitis B surface antigen and hepatitis B 'e' antigen seroprevalence of mothers and their children aged 6-36 months and to assess the risk of hepatitis B transmission occurring in infants born to hepatitis B surface antigen positive mothers in Pakistan. Methods: Mothers and their children were selected from eight districts of three provinces that have been identified as high hepatitis B prevalence areas between May 2010 to February 2011. Ages of the children and their vaccination status were obtained from the lady health workers' registers and also verified from the mothers. Five ml of blood was drawn from all the children and their mothers for testing. All sera were tested for anti-hepatitis B. Those found negative were run for HBsAg the sueface antigen and those positive for it were further run for hepatitis B 'e' antigen. All tests were run on Abbott machine using chemiluminesence method. EPI-info 12 was used for statistical purposes. Results: A total of 1561 mothers and their 1612 children were tested. Among the mothers, 590 (37.8%) were hepatitis B antibody positive. Remaining 971 (62.2%) samples were tested for surface antigen and 123 (12.7%) were found positive of which 27 (22%) showed HBeAg positivity. Out of 1612 children tested, 975 (60.5%) were positive. Remaining 637 (39.5%) were tested for surface antigen and 49 (8%) were found positive of which 24 (49%) were HBeAg positive with a perinatal hepatitis B virus transmission rate of 5.4% by 12 months of age. Of the 123 surface antigen positive mothers, 18 (14.6%) had children who were also positive, while of the 1489 children born to the 1438 surface antigen negative mothers, 31 (2.1%) were positive. Children born to surface antigen positive mothers had eight times higher risk of getting hepatitis B virus infection and the risk rose to 17 times if the mother was also HBeAg positive. Hepatitis B vaccination record showed that 1229 (76.25%) children were vaccinated at six weeks

    Full Text Available Antiretroviral therapy contributes to decreasing morbidity and mortality, and ultimately to increasing survival. In Brazil, there are regional differences in HIV epidemiology regarding pregnant women and children with HIV/AIDS. This study evaluates survival time after AIDS diagnosis in 914 children infected by mother-to-child transmission, reported between 1983 and 1998 and followed until 2002, in Brazil's five regions. Time between birth and HIV diagnosis decreased over the years, mainly in the South and Southeast Regions. There was a significant improvement in survival; more than 75% of cases were still living four years after diagnosis in the 1997-1998 group. This Brazilian study demonstrates that even with regional inequalities in health care infrastructure it is possible for a developing country to establish an effective system of universal and free access to antiretroviral therapy that produces a significant increase in survival for children with AIDS.A terapia anti-retroviral contribui para a diminuição da morbidade e da mortalidade, com conseqüente aumento da sobrevida. No Brasil, há diferenças regionais relativas à dinâmica da epidemia do HIV e ao seu enfrentamento no grupo das gestantes e das crianças com HIV/AIDS. Este estudo verifica o tempo de sobrevida após o diagnóstico de AIDS em 914 crianças infectadas por transmissão vertical, entre os anos de 1983 e 1998, e acompanhadas até 2002, nas cinco regiões brasileiras. O tempo do nascimento ao diagnóstico de infecção pelo HIV, ao longo dos anos, apresenta uma diminuição, principalmente nos estados das regiões Sul e Sudeste. Houve melhora significativa da sobrevivência, mais de 75% dos casos ainda estavam vivendo quatro anos após o diagnóstico, no grupo de 1997 e 1998.

    Although breast-feeding is nature's way of providing nutrition to the baby, in HIV positive mothers this has been identified as one of the means through which HIV infection is transmitted from the mother to the child. In Africa where children under the age of 5 are killed by preventable diseases like diarrhoea, the issue of HIV transmission through breast feeding poses an added huge problem. Research has, however shown that exclusive infant feeding, be it breast or formula, reduces the risk substantially. It is imperative that mothers be informed about safer methods of infant feeding so that HIV infection is kept to a minimum. The objective of the study was to explore and describe the knowledge that pregnant women had about mother to child transmission of HIV infection through breast-feeding. A non-experimental quantitative exploratory and descriptive research design was used to explore the knowledge women had on mother to child transmission of HIV infection through breast-feeding. From the data collected, it showed that although women were aware of the susceptibility of children to HIV infection if fed on breast and formula feeds simultaneously by HIV positive mothers, exclusive feeding was a problem as people associated the practise with a positive HIV status. Women who had not disclosed their HIV status and were HIV positive, found it difficult to comply with the requirement to exclusively feed their infants. These either continued with complementary feeds or did not collect the free formula milk supply preferring instead to buy the formula feeds privately. In this study it was recommended that information on transmission of HIV infection from mother to child through breast -feeding including the benefits of exclusive infant feeding, be it breast or formula, for the first three to six months be provided to the community so that relatives can support the mother on infant feeding method of choice.

    Full Text Available Mother-to-child transmission of HIV (MTCT remains the most prevalent source of pediatric HIV infection. Most PMTCT (prevention of mother-to-child transmission of HIV programs have concentrated monitoring and evaluation efforts on process rather than on outcome indicators. In this paper, we review service data from 28,320 children born to HIV-positive mothers to estimate MTCT rates.This study analyzed DNA PCR results and PMTCT data from perinatally exposed children zero to 12 months of age from five Zambian provinces between September 2007 and July 2010.The majority of children (58.6% had a PCR test conducted between age six weeks and six months. Exclusive breastfeeding (56.8% was the most frequent feeding method. An estimated 45.9% of mothers were below 30 years old and 93.3% had disclosed their HIV status. In terms of ARV regimen for PMTCT, 32.7% received AZT+single dose NVP (sdNVP, 30.9% received highly active antiretroviral treatment (HAART, 19.6% received sdNVP only and 12.9% received no ARVs. Transmission rates at six weeks when ARVs were received by both mother and baby, mother only, baby only, and none were 5.8%, 10.5%, 15.8% and 21.8% respectively. Transmission rates at six weeks where mother received HAART, AZT+sd NVP, sdNVP, and no intervention were 4.2%, 6.8%, 8.7% and 20.1% respectively. Based on adjusted analysis including ARV exposures and non ARV-related parameters, lower rates of positive PCR results were associated with 1 both mother and infant receiving prophylaxis, 2 children never breastfed and 3 mother being 30 years old or greater. Overall between September 2007 and July 2010, 12.2% of PCR results were HIV positive. Between September 2007 and January 2009, then between February 2009 and July 2010, proportions of positive PCR results were 15.1% and 11% respectively, a significant difference.The use of ARV drugs reduces vertical transmission of HIV in a program setting. Non-chemoprophylactic factors also play a significant

Mother-to-child transmission is the main source of spreading HIV infection to the child with frequency is as high as 25-30%. This may occurred because of the intrapartum maternal blood exposure, infected genital tract secretions and during breastfeeding. The right combination of ARV treatment and elective section caesarean delivery has been proved to reduce the mother-to-child transmission of HIV infection prevalence and preventing obstetric complications significantly. Consultation and follow up with specialists is highly recommended.

    Full Text Available Prevention of mother-to-child HIV transmission (PMTCT strategies include combined short-course antiretrovirals during pregnancy (Option A, triple-drug antiretroviral treament (ART during pregnancy and breastfeeding (Option B, or lifelong ART (Option B+. The WHO also recommends ART for HIV treatment and prevention of sexual transmission of HIV. The impact of PMTCT strategies on prevention of sexual HIV transmission of HIV is not known. We estimated the population-level impact of PMTCT interventions on heterosexual HIV transmission in southwestern Uganda and KwaZulu-Natal, South Africa, two regions with different HIV prevalence and fertility rates.We constructed and validated dynamic, stochastic, network-based HIV transmission models for each region. PMTCT Options A, B, and B+ were simulated over ten years under three scenarios: 1 current ART and PMTCT coverage, 2 current ART and high PMTCT coverage, and 3 high ART and PMTCT coverage. We compared adult HIV incidence after ten years of each intervention to Option A (and current ART at current coverage.At current coverage, Options B and B+ reduced heterosexual HIV incidence by about 5% and 15%, respectively, in both countries. With current ART and high PMTCT coverage, Option B+ reduced HIV incidence by 35% in Uganda and 19% in South Africa, while Option B had smaller, but meaningful, reductions. The greatest reductions in HIV incidence were achieved with high ART and PMTCT coverage. In this scenario, all PMTCT strategies yielded similar results.Implementation of Options B/B+ reduces adult HIV incidence, with greater effect (relative to Option A at current levels in Uganda than South Africa. These results are likely driven by Uganda's higher fertility rates.

    Full Text Available Background & objectives: Mother-to-child transmission (MTCT is the most significant route of HIV transmission in children below the age of 15 yr. In India, perinatal HIV transmission, even after treatment, accounts for 5.4 per cent of HIV cases. The present study was conducted to evaluate the efficacy of anti-retro viral therapy (ART or prophylactic treatment (PT to control maternal viral load in HIV positive women, and its effect on vertical HIV transmission to their infants. Methods: A total of 58 HIV positive women were enrolled at the time of delivery and their plasma samples were obtained within 24 h of delivery for estimation of viral load. Viral load analysis was completed in 38 women. Infants received single dose nevirapine within 2 h of birth and zidovudine for 6 wk. At the end of 18 month follow up, HIV positive or negative status was available in 28 infants. Results: Results revealed undetectable levels of viral load in 58.3 per cent of women with ART compared to 30.7 per cent of women with PT. No women on ART had viral load more than 10,000 copies/ml, whereas seven (26.9%, P=0.07 women receiving PT had this viral load. Median CD4 count of women on PT (483 cells/μl was high compared to the women on ART (289 cells/ μl. At the end of 18 months follow up, only two children were HIV positive, whose mothers were on PT. One had in utero transmission; infection detected within 48 h of delivery, while the other child was infected post partum as HIV was detected at six months follow up. Interpretation & conclusions: Women who received a single dose of nevirapine during delivery had higher levels of viral load than women on ART. Combination drug therapy for pregnant women is now a standard of care in most of the western countries; use of nevirapine monotherapy at the time of delivery in our settings is not effective in controlling viral load. This highlights initiation of ART in pregnant women to control their viral load and thus to inhibit

    Full Text Available Prevention of mother-to-child transmission (PMTCT programmes have improved maternalhealth outcomes and reduced the incidence of paediatric HIV, resulting in improved childhealth and survival. Nevertheless, high-risk vertical exposures remain common and areresponsible for a high proportion of transmissions. In the absence of antiretrovirals (ARVs,an 8- to 12-hour labour has approximately the same 15% risk of transmission as 18 monthsof mixed feeding. The intensity of transmission risk is highest during labour and delivery;however, the brevity of this intra-partum period lends itself to post-exposure interventions toreduce such risk. There is good evidence that infant post-exposure prophylaxis (PEP reducesintra-partum transmission even in the absence of maternal prophylaxis. Recent reports suggestthat infant combination ARV prophylaxis (cARP is more efficient at reducing intra-partumtransmission than a single agent in situations of minimal pre-labour prophylaxis. Guidelinesfrom the developed world have incorporated infant cARP for increased-risk scenarios. Incontrast, recent guidelines for low-resource settings have rightfully focused on reducingpostnatal transmission to preserve the benefits of breastfeeding, but have largely ignored thepotential of augmented infant PEP for reducing intra-partum transmissions. Minimal prelabourprophylaxis, poor adherence in the month prior to delivery, elevated maternal viralload at delivery, spontaneous preterm labour with prolonged rupture of membranes andchorioamnionitis are simple clinical criteria that identify increased intra-partum transmissionrisk. In these increased-risk scenarios, transmission frequency may be halved by combiningnevirapine and zidovudine as a form of boosted infant PEP. This strategy may be important toreduce intra-partum transmissions when PMTCT is suboptimal.

    By the year 2000 there will be six million pregnant women and five to ten million children infected with HIV-1. Intervention strategies have been planned and in some instances already started. A timely and cost-effective strategy needs to take into account that most HIV-1 infected individuals reside in developing countries. Further studies are needed on immunological and virological factors affecting HIV-1 transmission from mother to child, on differential disease progression in affected children, and on transient infection.

    2013-01-01

    The use of antiretroviral drugs (ARVDs) in a mother and a child can reduce the risk of vertical transmission of human immunodeficiency virus (HIV) to less than 1%; therefore, highly active antiretroviral therapy is used in all pregnant women regardless of indications for HIV-infection treatment. The major requirements for choosing an ARVD to prevent mother-to-child HIV transmission are its high safety for a pregnant woman, a fetus, and a baby and its high therapeutic efficacy. Clinical trials of darunavir (DRV) in adults and children have shown a high virologic response, good tolerance, and safety. Trials and observations have demonstrated the high efficacy and safety of a DRV when used in pregnant women. Pharmacokinetic studies in pregnant women have indicated the effective and well-tolerated concentration of a DRV when it is co-administered with low-dose ritonavir, which permits the use of a DRV for both the prevention of mother-to-child HIV transmission and the treatment of pregnant women who require antiretroviral therapy. The Russian clinical protocol "Use of ARVDs in the package of measures for the prevention of mother-to-child HIV transmission" approved by the National Scientific Society of Infectiologists in 2013 recommends DRV as an alternative drug in antiretroviral therapy regimens for pregnant women to prevent mother-to-child HIV transmission and to treat maternal HIV infection.

    Full Text Available Context: An estimated 430,000 children were newly infected with HIV in 2008, over 90% of them through mother-to-child transmission (MTCT. Without intervention, the risk of MTCT ranges from 20% to 45% as per the World Health Organization (WHO. Aim: To find the uptake of Prevention of Parent to Child Transmission of HIV/AIDS (PPTCT services during pregnancy. Setting and Design: Cross-sectional study. Materials and Methods: Ethical approval and informed consent was taken. Uptake of PPTCT services by the mother was obtained in 222 pregnancies. This was compared with the HIV status of children born to them. Statistical Analysis Used: Percentages. Results: In 25.7% pregnancies, the mothers were tested for HIV. One child was born was to a mother who had tested HIV negative in pregnancy. In 50% of the mother-child pairs, both mother and child received PPTCT. Where both the mother and child received PPTCT, only 13.3% children born were HIV positive as against 40% children who were HIV positive where neither mother nor the child had received PPTCT. Conclusion: Uptake of PPTCT services was low. In countries like India where the chances of parent to child transmission of HIV are likely to be more than in developed countries due to breastfeeding practices, the uptake of PPTCT services should be maximized to decrease the burden of pediatric HIV because even a single pediatric HIV infection counts. All the pregnant women need to be voluntarily tested twice for HIV in pregnancy, in which the second test for HIV may be in late pregnancy.

    In 2012, an estimated 35.3 million people lived with HIV, while approximately two million new HIV infections were reported. Community-based interventions (CBIs) for the prevention and control of HIV allow increased access and ease availability of medical care to population at risk, or already infected with, HIV. This paper evaluates the impact of CBIs on HIV knowledge, attitudes, and transmission. We included 39 studies on educational activities, counseling sessions, home visits, mentoring, women's groups, peer leadership, and street outreach activities in community settings that aimed to increase awareness on HIV/AIDS risk factors and ensure treatment adherence. Our review findings suggest that CBIs to increase HIV awareness and risk reduction are effective in improving knowledge, attitudes, and practice outcomes as evidenced by the increased knowledge scores for HIV/AIDS (SMD: 0.66, 95% CI: 0.25, 1.07), protected sexual encounters (RR: 1.19, 95% CI: 1.13, 1.25), condom use (SMD: 0.96, 95% CI: 0.03, 1.58), and decreased frequency of sexual intercourse (RR: 0.76, 95% CI: 0.61, 0.96). Analysis shows that CBIs did not have any significant impact on scores for self-efficacy and communication. We found very limited evidence on community-based management for HIV infected population and prevention of mother- to-child transmission (MTCT) for HIV-infected pregnant women. Qualitative synthesis suggests that establishment of community support at the onset of HIV prevention programs leads to community acceptance and engagement. School-based delivery of HIV prevention education and contraceptive distribution have also been advocated as potential strategies to target high-risk youth group. Future studies should focus on evaluating the effectiveness of community delivery platforms for prevention of MTCT, and various emerging models of care to improve morbidity and mortality outcomes.

    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. Infant HIV infection was determined by serial HIV DNA PCR testing. Maternal syphilis was tested by VDRL and confirmatory treponemal antibodies. Results A total of 899 mother-infant pairs were evaluated. Over 30% had at least one of the following infections (TP, CT, NG, and/or CMV) detected at the time of delivery. High rates of TP (8.7%), CT (17.8%), NG (4%), and CMV (6.3%) were observed. HIV MTCT was 9.1% (n = 82 infants). HIV MTCT was 12.5%, 10.3%, 11.1%, and 26.3% among infants born to women with CT, TP, NG or CMV respectively. Forty-two percent of HIV-infected infants were born to women with at least one of these 4 infections. Women with these infections were nearly twice as likely to have an HIV-infected infant (aOR 1.9, 95% CI 1.1–3.0), particularly those with 2 STIs (aOR 3.4, 95% CI 1.5–7.7). Individually, maternal CMV (aOR 4.4 1.5–13.0) and infant congenital CMV (OR 4.1, 95% CI 2.2–7.8) but not other STIs (TP, CT, or NG) were associated with an increased risk of HIV MTCT. Conclusion HIV-infected pregnant women identified during labor are at high risk for STIs. Co-infection with STIs including CMV nearly doubles HIV MTCT risk. CMV infection appears to confer the largest risk of HIV MTCT. Trial registration NCT00099359. PMID:29304083

    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. Recent discoveries providing evidence of robust immune responses to HIV in infants open new and exciting prospects for paediatric HIV vaccines. Moreover, successful vaccination of infants has a different set of requirements than vaccination of adults and may be easier to achieve. Proof-of-concept has been established over the last two decades that passively administered HIV-1 Env-specific monoclonal antibody (mAbs) can prevent chimeric simian human immunodeficiency virus (SHIV) transmission to newborn nonhuman primates. There has been tremendous progress in isolating and characterizing broadly neutralizing antibodies to HIV, and clinical testing of these antibodies for treatment and prevention in both infants and adults is a major effort in the field. Immune-based interventions need to be actively explored as they can provide critically important tools to address persistent challenges in MTCT prevention. It is a pivotal time for the field with active discussions on the best strategy to further reduce HIV infection of infants and accomplish the World Health Organization Fast-Track 2030 goals to eliminate new paediatric HIV infections. © 2017 The Authors.

    Both HIV and HBV infection have become major health problems, of global concern, due to the high prevalence in the past few decades. Data from cumulated epidemiological surveys have shown the links between maternal HIV or HBV infection and adverse outcomes on pregnancy. Maternal HIV or HBV infection may also increase the mother-to-child (MTCT) transmission of the two diseases. However, association between HIV-HBV co-infection and adverse pregnancy is still inconclusive. Does maternal HIV-HBV co-infection have an impact on mother-to-child transmission on either HIV or HBV? Study on effective precautionary measures to promote both maternal and child's health is deemed necessary.

  18. Integrating HIV, hepatitis B and syphilis screening and treatment through the Maternal, Newborn and Child Health platform to reach global elimination targets

    Full Text Available Every year, an estimated 180 000 babies in the Western Pacific Region are infected by hepatitis B, 13 000 by syphilis and 1400 by HIV through mother-to-child transmission.1 These infections can be largely prevented by antenatal screening, treatment and timely vaccination for newborns. Despite challenges in controlling each disease, major achievements have been made. National immunization programmes have reduced the regional hepatitis B prevalence from over 8% in 1990 to 0.93% among children born in 2012. In addition, HIV testing and treatment have helped keep the regional prevalence of HIV infections at 0.1%. In contrast, the number of maternal syphilis cases is still high in the Western Pacific Region, with an estimated 45 million cases in 2012. Elimination of mother-to-child transmission of these infections cannot be achieved through vertically applied programming and require using and augmenting to the shared Maternal, Newborn and Child Health platform to coordinate, integrate and enable cost efficiencies for these elimination efforts. The Regional Framework for Triple Elimination of Mother-to-Child Transmission of HIV, Hepatitis B and Syphilis in Asia and the Pacific 2018–2030 offers such a coordinated approach towards achieving the triple elimination of mother-to-child transmission of HIV, hepatitis B and syphilis and provides guidance for decision-makers, managers and health professionals working in programmes addressing maternal, newborn and child health, HIV, hepatitis, sexually transmitted infections and immunization.

    The BED assay was developed to estimate the proportion of recent HIV infections in a population. We used the BED assay as a proxy for acute infection to quantify the associated risk of mother-to-child-transmission (MTCT) during pregnancy and delivery. Design A total of 3773 HIV-1 sero-positive women were tested within 96 h of delivery using the BED assay, and CD4 cell count measurements were taken. Mothers were classified according to their likelihood of having recently seroconverted. The risk of MTCT in utero and intra-partum was assessed comparing different groups defined by BED and CD4 cell count, adjusting for background factors using multinomial logistic models. Compared with women with BED ≥ 0.8/CD4 ≥ 350 (typical of HIV-1 chronic patients) there was insufficient evidence to conclude that women presenting with BED pregnancy.

    Effective strategies are urgently needed to reduce mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) through breast-feeding in resource-limited settings. Women with HIV-1 infection who were breast-feeding infants were enrolled in a randomized, phase 3 trial in Blantyre, Malawi. At birth, the infants were randomly assigned to one of three regimens: single-dose nevirapine plus 1 week of zidovudine (control regimen) or the control regimen plus daily extended prophylaxis either with nevirapine (extended nevirapine) or with nevirapine plus zidovudine (extended dual prophylaxis) until the age of 14 weeks. Using Kaplan-Meier analyses, we assessed the risk of HIV-1 infection among infants who were HIV-1-negative on DNA polymerase-chain-reaction assay at birth. Among 3016 infants in the study, the control group had consistently higher rates of HIV-1 infection from the age of 6 weeks through 18 months. At 9 months, the estimated rate of HIV-1 infection (the primary end point) was 10.6% in the control group, as compared with 5.2% in the extended-nevirapine group (P<0.001) and 6.4% in the extended-dual-prophylaxis group (P=0.002). There were no significant differences between the two extended-prophylaxis groups. The frequency of breast-feeding did not differ significantly among the study groups. Infants receiving extended dual prophylaxis had a significant increase in the number of adverse events (primarily neutropenia) that were deemed to be possibly related to a study drug. Extended prophylaxis with nevirapine or with nevirapine and zidovudine for the first 14 weeks of life significantly reduced postnatal HIV-1 infection in 9-month-old infants.

    Introduction: Vertical transmission of AIDS is defined as a transmission that occurs from mother to child during pregnancy, birth or breastfeeding and is today the main route of HIV infection in children under 13 in the world. Objective: in order to understand the history of life and the therapeutic itinerary of HIV positive pregnant women, it was conducted a study with a qualitative approach to social phenomenology as theoretical and methodological references. Methods: For the study, a Likert-type questionnaire and a semi structured interview were applied for each participant. Results and Discussion: The study revealed the dilemmas faced and the actions taken by these women, HIV positive mothers, waiting for the diagnosis of the fetus, both participants in the Zero Vertical Transmission Program Clinic STD / AIDS in the city of Sorocaba, state of São Paulo. Prejudice and stigma related to AIDS is the leading source stressful and promoter of social isolation of this population, which faces the prejudice by relying mainly on their children and on their religiosity/spirituality as the second largest mainstay. Women often do not see their companion as supportive and fight back the situation of suffering, anguish, fear, and disappointment with their own courage and hope to overcome the adversity caused by the disease. Conclusion: The implications of this study suggest the risk and protective factors promoting resilience in this clientele, besides suggesting creating spaces that encourage discussion of the medical context, cultural, social and economic development in which these women are entered and that influence their daily decisions

  9. Phosphazide (nikavir) is a highly effective drug for the treatment of HIV/AIDS infection.

    Galegov, George A

    Federation Convincing evidence for high therapeutic activity and tolerability of Phosphazide in the treatment of HIV/AIDS-infection is given. Phosphazide is currently used in various regimens of highly active antiretroviral therapy, as well as in the HIV therapy in patients with simultaneously acquired chronic hepatitis C or tuberculosis. Therapeutic possibilities of Phosphazide were clearly manifested in the prevention of HIV transmission from mother to child. There is every reason to use Phosphazide in first-line antiretroviral therapy.

    To analyze the outcomes of Prevention of Parent to Child Transmission (PPTCT) of HIV program in an urban Southern Indian setting. Observational study. Anti-retroviral Therapy (ART) Centers/ Integrated Counseling and Testing Centers (ICTC) at four government Obstetrics Institutes in an urban area. 100 HIV-positive pregnant women and their infants delivered in the study centers. Triple drug ART to HIV-positive pregnant women was started for maternal indications only. Rest of the pregnant women were given single dose Nevirapine (200 mg) at the onset of labor. All infants were given single dose Nevirapine (2 mg/kg) prophylaxis, according to National AIDS Control Organization guidelines. Mothers were counseled regarding breastfeeding and artificial feeding, and the choice was left to them. Whole blood HIV 1 DNA PCR was done for all infants at 6 weeks of life. A second PCR was done at 6 months or 6 weeks after stopping breastfeeds. PCR-positive infants were started on ART, and were followed-up till18 months of life. Four infants were PCR-positive for HIV. All of them were breastfed. They were born to mothers of HIV stage 1 or 2 who were not on ART as CD4 counts were >350 cells/mm3. Among the mothers in Stage 3 or 4 or CD4 count ART, none of the infants was HIV-positive. The cumulative HIV-free survival at 18 months was 94%. Parent-to-child transmission rate in HIV was low with the currently used strategies. Triple drug ART to mother reduces mother-to-child transmission despite advanced maternal stage or low CD4 counts.

    Human immunodeficiency virus type 1 (HIV-1) is pandemic, but its contemporary global transmission network has not been characterized. A better understanding of the properties and dynamics of this network is essential for surveillance, prevention, and eventual eradication of HIV. Here, we apply a simple and computationally efficient network-based approach to all publicly available HIV polymerase sequences in the global database, revealing a contemporary picture of the spread of HIV-1 within and between countries. This approach automatically recovered well-characterized transmission clusters and extended other clusters thought to be contained within a single country across international borders. In addition, previously undescribed transmission clusters were discovered. Together, these clusters represent all known modes of HIV transmission. The extent of international linkage revealed by our comprehensive approach demonstrates the need to consider the global diversity of HIV, even when describing local epidemics. Finally, the speed of this method allows for near-real-time surveillance of the pandemic's progression.

    Full Text Available Women have emerged as the fastest growing human immunodeficiency virus (HIV infected population worldwide, mainly because of the increasing occurrence of heterosexual transmission. Most infected women are of reproductive age and one of the greatest concerns for both women and their physicians is that more than 1,600 infants become infected with HIV each day. Almost all infections are a result of mother-to-child transmission of HIV. With the advent of combination antiretroviral therapies, transmission rates lower than 2% have been achieved in clinical studies. Antiretroviral compounds differ from most other new pharmaceutical agents in that they have become widely prescribed in pregnancy in the absence of proof of safety. We reviewed antiretroviral agents used in pregnant women infected with human immunodeficiency virus, mother-to-child transmission, and their consequences for infants.

    The AIDS epidemic has spread rapidly in Africa among the urban impoverished where multiple sexual partners and sexually transmitted diseases are common. Over 80% of the 9 million Africans who will develop AIDS before the year 2000 will have been contaminated sexually. Poverty, multiple sexual partners in the framework of prostitution, and drug addiction are responsible for rapid spread of HIV infection in Southeast Asia, the West India, and Brazil. Drug addiction has played a major role in diffusion of HIV into the general population of Europe and the US. Prevalence rates are much higher in sexually transmitted disease centers in France and the US than among blood donors or pregnant women. Sexually transmitted diseases and heterosexual transmission have been studied in Africas since diagnostic tests became available. Several studies, the majority conducted among prostitutes in Nairobi or Kinshasa and their clients, allow establishment of a list of sexually transmitted diseases associated with increased risk of seroconversion. Genital ulcers within the past 6 months presented a relative risk of 2-4 depending on the series. Urethral or cervical gonorrhea has a lower relative risk of 1.2 in most studies. Absence of circumcision was also a risk factor. Studies were subsequently conducted in Europe on factors favoring sexual transmission. 513 heterosexual couples together for a minimum duration of 18 months and an average of 38 months were included in the Multicenter European Study conducted in 10 centers in 9 countries. The "index" subject was male in 400 cases and female in 113. At entry into the study, 73 of 400 males (18.2%) and 10 of 113 females (8.8%) had already infected their partners. Duration of union, frequency of intercourse, mode of transmission of the index subject, and oral contraceptive use had no effect on risk of transmission. Factors increasing risk of infection included the severity of immunosuppression of the index subject, whether judged by

    Full Text Available BACKGROUND: Uganda has one of the highest total fertility rates (TFR worldwide. We compared the effects of antiretroviral (ARV prophylaxis for the prevention of mother-to-child HIV transmission (PMTCT to that of existing family planning (FP use and estimated the burden of pediatric HIV disease due to unwanted fertility. METHODOLOGY/PRINCIPAL FINDINGS: Using the demographic software Spectrum, a baseline mathematical projection to estimate the current pediatric HIV burden in Uganda was compared to three hypothetical projections: 1 without ARV-PMTCT (to estimate the effect of ARV-PMTCT, 2 without contraception (effect of existing FP use, 3 without unwanted fertility (effect of unmet FP needs. Key input parameters included HIV prevalence, ARV-PMTCT uptake, MTCT probabilities, and TFR. We estimate that in 2007, an estimated 25,000 vertical infections and 17,000 pediatric AIDS deaths occurred (baseline projection. Existing ARV-PMTCT likely averted 8.1% of infections and 8.5% of deaths. FP use likely averted 19.7% of infections and 13.1% of deaths. Unwanted fertility accounted for 21.3% of infections and 13.4% of deaths. During 2008-2012, an estimated 131,000 vertical infections and 71,000 pediatric AIDS deaths will occur. The projected scale up of ARV-PMTCT (from 39%-57% may avert 18.1% of infections and 24.5% of deaths. Projected FP use may avert 21.6% of infections and 18.5% of deaths. Unwanted fertility will account for 24.5% of infections and 19.8% of deaths. CONCLUSIONS: Existing FP use contributes as much or more than ARV-PMTCT in mitigating pediatric HIV in Uganda. Expanding FP services can substantially contribute towards PMTCT.

  17. Phylogenetic Inference of HIV Transmission Clusters

    Full Text Available Better understanding the structure and dynamics of HIV transmission networks is essential for designing the most efficient interventions to prevent new HIV transmissions, and ultimately for gaining control of the HIV epidemic. The inference of phylogenetic relationships and the interpretation of results rely on the definition of the HIV transmission cluster. The definition of the HIV cluster is complex and dependent on multiple factors, including the design of sampling, accuracy of sequencing, precision of sequence alignment, evolutionary models, the phylogenetic method of inference, and specified thresholds for cluster support. While the majority of studies focus on clusters, non-clustered cases could also be highly informative. A new dimension in the analysis of the global and local HIV epidemics is the concept of phylogenetically distinct HIV sub-epidemics. The identification of active HIV sub-epidemics reveals spreading viral lineages and may help in the design of targeted interventions.HIVclustering can also be affected by sampling density. Obtaining a proper sampling density may increase statistical power and reduce sampling bias, so sampling density should be taken into account in study design and in interpretation of phylogenetic results. Finally, recent advances in long-range genotyping may enable more accurate inference of HIV transmission networks. If performed in real time, it could both inform public-health strategies and be clinically relevant (e.g., drug-resistance testing.

    Exclusive breastfeeding has the potential to reduce infant and under-five mortality, but research shows the practice is not widespread in resource-poor settings of sub-Saharan Africa. We explored factors influencing the decision to exclusively breastfeed among HIV-positive mothers accessing interventions for prevention of mother-to-child transmission of HIV in selected sites of Zambia. This exploratory qualitative study was embedded in research conducted on: HIV and infant feeding; choices and decision-outcomes in the context of prevention of mother-to-child transmission among HIV-positive mothers in Zambia. Thirty HIV-positive mothers and six key informants were recruited from two health facilities providing mother-to-child HIV transmission prevention services. A semi-structured guide was used to conduct interviews, which were digitally recorded and simultaneously transcribed. Data coding and analysis was done with the support of QRS Nvivo 10 version software. Despite the known benefits of exclusive breastfeeding, gaps in understanding and potential for behaviour change remained. We found that information promoting exclusive breastfeeding may have been understood by mothers as instructions from the health care workers indicating how to feed their HIV-exposed babies rather than as an option for the mothers' own informed-decision. This understanding influenced a mother's perceptions of breast milk safety while on antiretroviral medicine, of the formula feeding option, and of the baby crying after breastfeeding. The meanings mothers attached to exclusive breastfeeding thus influenced their understanding of breast milk insufficiency, abrupt weaning and mixed feeding in the context of preventing mother-to-child transmission of HIV. In order to enhance feeding practices for HIV-exposed infants, our study suggests a broader health campaign supporting all mothers to exclusively breastfeed.

    To provide further evidence for the heterosexual transmission of the acquired immunodeficiency syndrome (AIDS) in Greece we examined 53 Greek female steady heterosexual partners of 53 anti-HIV-positive men. Human immunodeficiency virus (HIV) transmission was estimated by the detection of anti-HIV antibodies. Our results showed that 27.8% (5 of 18) of the female partners of bisexuals, 33.3% (2 of 6) of intravenous drug abusers (IVDA), and 100% (4 of 4) of those who had lived for a long time in Africa were found anti-HIV positive. In contrast, only 4% (1 of 25) of the studied sexual partners of hemophiliac carriers were found to be HIV seropositive. The use of condoms seemed to be the most important factor in reducing HIV transmission. According to our results the duration of sexual relationships and the practice of anal intercourse did not increase the possibility of seroconversion. These results confirm the heterosexual transmission of HIV. However, further studies should be conducted to evaluate the relative role of various risk factors and the overall importance of heterosexual spread of HIV infections.

    2017-06-01

    With the widespread use of antiretroviral therapy and successful prevention of mother-to-child transmission the development of HIV-negative children with HIV-positive parents has become an important focus. There is considerable evidence that children's developmental risk is heightened because a parental HIV-diagnosis is associated with a range of potential problems such as depression, stigma and financial difficulties. Up to a third of children in sub-Saharan Africa (SSA) are cared for by an HIV-positive parent or caregiver. We review the mechanisms by which HIV affects parenting including its negative effects on parental responsiveness in the early years of parenting and parental avoidant coping styles and parenting deficits in the later years. We describe low-cost parenting interventions suited for low resourced HIV endemic settings. Copyright © 2017. Published by Elsevier Ltd.

    1997-05-01

    The consistent use of latex condoms continues to be advocated for primary prevention of HIV infection despite limited quantitative evidence regarding the effectiveness of condoms in blocking the sexual transmission of HIV. Although recent meta-analyses of condom effectiveness suggest that condoms are 60 to 70% effective when used for HIV prophylaxis, these studies do not isolate consistent condom use, and therefore provide only a lower bound on the true effectiveness of correct and consistent condom use. A reexamination of HIV seroconversion studies suggests that condoms are 90 to 95% effective when used consistently, i.e. consistent condom users are 10 to 20 times less likely to become infected when exposed to the virus than are inconsistent or non-users. Similar results are obtained utilizing model-based estimation techniques, which indicate that condoms decrease the per-contact probability of male-to-female transmission of HIV by about 95%. Though imperfect, condoms provide substantial protection against HIV infection. Condom promotion therefore remains an important international priority in the fight against AIDS.

    2016-03-01

    With the rapid roll-out of combination antiretroviral therapy to prevent mother-to-child transmission of HIV, there is an annual increase in the number of uninfected infants born to HIV-infected women. Although the introduction of combination antiretroviral therapy has vastly improved pregnancy outcome and the health of infants born to HIV-infected women, concerns remain regarding the impact the maternal HIV infection on the pregnancy outcome and the health of HIV-exposed uninfected infants. Maternal HIV infection is associated with negative pregnancy outcomes such as low birth weight. In addition, an increased susceptibility to infections is reported in HIV-exposed uninfected infants compared with infants born to uninfected women. Studies have shown that HIV-exposure affects the maternal/fetal unit, with increase of proinflammatory cytokine produced by placental cells, as well as altered infant immune responses. These changes could provide the underlying conditions for negative pregnancy outcomes and facilitate mother-to-child transmission of HIV in the infant. Further studies are required to understand the underlying mechanisms and investigate whether these altered infant immune responses persist and have clinical consequences beyond childhood. HIV infection in pregnant women is associated with altered immune responses in HIV-infected women and their offspring with clinical consequences for pregnancy outcome and the HIV-exposed uninfected infant. Further studies are required to address the origin and long-term consequences of prenatal HIV-exposure and subsequent immune activation for infant health.

    The infection route of Helicobacter pylori has been recognized to be mainly intrafamilial, preferentially mother-to-child, especially in developed countries. To determine the transmission route, we examined whether multilocus sequence typing (MLST) was useful for analysis of intrafamilial infection. The possibility of intraspousal infection was also evaluated. Clonal relationships between strains derived from 35 index Japanese pediatric patients, and their family members were analyzed by two genetic typing procedures, MLST and random amplified polymorphic DNA (RAPD) fingerprinting. Mostly coincident results were obtained by MLST and RAPD. By MLST, the allele of loci in the isolates mostly matched between the index child and both the father and mother for 9 (25.7%) of the 35 patients, between the index child and the mother for 25 (60.0%) of the 35 patients. MLST is useful for analyzing the infection route of H. pylori as a highly reproducible method. Intrafamilial, especially mother-to-children and sibling, infection is the dominant transmission route. Intraspousal infection is also thought to occur in about a quarter in the Japanese families. © 2015 John Wiley & Sons Ltd.

    Youth carry the highest incidence of HIV infection in the United States. Understanding adolescent and young adult (AYA) perspectives on HIV transmission risk is important for targeted HIV prevention. We conducted a mixed methods study with HIV-infected and uninfected youth, ages 18–24 years, from Atlanta, GA. We provided self-administered surveys to HIV-infected and HIV-uninfected AYAs to identify risk factors for HIV acquisition. By means of computer-assisted thematic analyses, we examined t...

    Since 1999 GHESKIO, a large voluntary counseling and HIV testing center in Port-au-Prince, Haiti, has had an ongoing collaboration with the Haitian Ministry of Health to reduce the rate of mother to child HIV transmission. There are limited data on the ability to administer complex regimens for reducing mother to child transmission and on risk factors for continued transmission and infant mortality within programmatic settings in developing countries. We analyzed data from 551 infants born to HIV-infected mothers seen at GHESKIO, between 1999 and 2005. HIV-infected mothers and their infants were given "short-course" monotherapy with antiretrovirals for prophylaxis; and, since 2003, highly active antiretroviral therapy (HAART) when clinical or laboratory indications were met. Infected women seen in the pre-treatment era had 27% transmission rates, falling to 10% in this cohort of 551 infants, and to only 1.9% in infants of women on HAART. Mortality rate after HAART introduction (0.12 per year of follow-up [0.08-0.16]) was significantly lower than the period before the availability of such therapy (0.23 [0.16-0.30], Pbirth weight on mortality and transmission were determined using univariate and multivariate analysis. Infant HIV-1 infection and low birth weight were associated with infant mortality in less than 15 month olds in multivariate analysis. Our findings demonstrate success in prevention of mother-to-child HIV transmission and mortality in a highly resource constrained setting. Elements contributing to programmatic success include provision of HAART in the context of a comprehensive program with pre and postnatal care for both mother and infant.

    HIV/AIDS has emerged as the single most formidable challenge to public health. School children of today are exposed to the risk of HIV/AIDS. The study was conducted to determine the knowledge among secondary school students regarding HIV/AIDS and provide suggestions for HIV/AIDS education in schools. A cross-sectional study was conducted among students of tenth to twelfth standard in the intermediate schools of Lucknow, India, from July to October 2011. A total of 215 students, both boys and girls, were enrolled in the study. In this study, for majority of the students (85%), the source of information about HIV/AIDS was the television. Regarding knowledge about modes of transmission of HIV/AIDS among girl students, 95.1% of them told that it is through unprotected sex. A total of 75.8% students said that it was transmitted from mother to child. It was observed that the knowledge of the school students was quite satisfactory for most of the variables like modes of transmission, including mother-to-child transmission of the disease. However, schools should come forward to design awareness campaigns for the benefit of the students.

    Round the clock (24 hours×7 days) HIV testing is vital to maintain a high prevention of mother to child transmission (PMTCT) coverage for women delivering in district health facilities. PMTCT coverage increases when most of the pregnant women will have their HIV status tested. Therefore routine offering of HIV testing should be integrated and seen as a part of comprehensive antenatal care. For women who miss antenatal care and deliver in a health facility without having had their HIV status tested, the labour and maternity ward could still serve as other entry points.

    Full Text Available The South African prevention of mother to child transmission programme has made excellentprogress in reducing vertical HIV transmission, and paediatric antiretroviral therapyprogrammes have demonstrated good outcomes with increasing treatment initiation inyounger children and infants. However, both in South Africa and across sub-Saharan African,lack of boosted peri-partum prophylaxis for high-risk vertical transmission, loss to followup,and failure to initiate HIV-infected infants on antiretroviral therapy (ART before diseaseprogression are key remaining gaps in neonatal HIV-related care. In this issue of the Southern African Journal of HIV Medicine, experts provide valuable recommendations for addressingthese gaps. The present article highlights a number of areas where evidence is lacking toinform guidelines and programme development for optimal neonatal HIV-related care.

    Full Text Available INTRODUCTION Routine antenatal screening for HIV combined with advances in highly active antiretroviral therapy has led to increased detection and effective treatment in pregnancy. AIM To know effectiveness of screening in antenatal mother and their husband for HIV status, seroprevalence rate among them and among their infants from a tertiary care hospital. We aim to outline key interventions which can influence the rate of mother to child transmission and how these are best incorporated into care of pregnant women and her baby including antenatal testing use of antiretroviral medication, management of labour and of breast-feeding. METHOD Retrospective analysis of Data over a period of six years available in Integrated counselling and Testing centre attached to Tertiary Care Government Medical College and Hospital Trichy, from 1 Jan 2010 to 31 Dec 2015. Data of Antenatal mothers screened and diagnosed as HIV Seropositive and its various outcomes related to these pregnancies were analysed. RESULTS Among 29215 women who were screened, 104 were found to be HIV seropositive. Declining seroprevalence rate from 0.66% in 2010 to 0.16% in 2015 noted. Among seropositive mothers, majority were in 25-34 years of age. Maximum incidence was in second gravida during initial years followed by primigravida, In subsequent years, declining seroprevalence rate in spouse and declining mother to child transmission rate were analysed. CONCLUSION Decreasing seroprevalence rate indicates effective counselling and intensive screening of HIV status of Antenatal mothers and their Husbands & their infants with effective Implementation of prevention of mother to child transmission programme and also effective treatment with highly active antiretroviral therapy.

    2007-01-01

    This paper traces the commonly believed three phases of the HIV/AIDs epidemic in China from the early 1980s to the present time and reviews how the Chinese Government and NGOs are dealing with the crisis. Transmission routes for HIV infection in China are thought to be via IDUs, blood plasma donors, sexual contacts and from mother-to-child transmissions. The author examined interventions for HIV/ AIDS prevention tried in other countries that could provide useful lessons learned and discussed how they could be adapted or replicated in China. While recognising the need for the treatment of HIV positive persons and AIDS patients, this paper is limited to suggesting a number of proven strategic interventions to prevent new HIV infections in China among the "general population", adolescents in schools, sex workers and their clients, injecting drug users, and, prevention of mother to child transmission of HIV/AIDS to stem the epidemic. An extensive literature search of articles in published academic journals, published and unpublished documents of international agencies and development NGOs and media reports was conducted for data source to this paper. Internet search engines such as ProQuest, PubMed, Google and Yahoo search engines were used as well as hard copies of reports and internal documents available at the UNFPA Country Technical Services Team's Office in Bangkok tapped for information.

    The desire for children is a legitimate aspiration that should be part of multidisciplinary care for all men, women or couples living with HIV. The use of effective antiretroviral therapy has revolutionized the prevention of sexual, as well as mother-to-child HIV transmission. When the HIV plasma viral load is undetectable on long-term antiretroviral therapy, the risk of mother-to-child transmission is <1% and the risk of heterosexual HIV transmission without condom use in a stable relationship is very low (estimated at less than 1/10,000) in the absence of inflammation of the genital tract. In a man with a long-term undetectable viral load, viral shedding in semen is uncommon, but may occur persistently or intermittently. The same appears true of viral shedding in the vaginal tract of women. Reproductive options are: natural conception, self-insemination when the woman is HIV-infected, assisted reproduction. Natural conception is now considered to be an acceptable option when the conditions are met, after exploring four aspects: (1) virological (viral load undetectable sustained for at least 6 months on therapy), (2) genital (absence of genital infections or lesions), (3) fertility (after appropriate evaluation) and (4) detecting the ovulation period to limit intercourse without condoms. Assisted reproduction has two objectives in the context of HIV, to allow the couple to conceive without abandoning condom use and/or to treat infertility. Copyright © 2014 Elsevier Masson SAS.

    Human immunodeficiency virus (HIV) has now transformed into a manageable chronic condition. Highly active antiretroviral therapy (HAART) has proven efficacious at controlling the disease progression. Based on compelling evidence, the Department of Health and Human Services (DHHS) and the Infectious Disease Society of America (IDSA) developed guidelines for the management of persons infected with HIV. However, there are approximately 50 000 new cases of HIV in the United States each year. In this article, we review proactive methods to reduce the transmission of HIV, which include reinforcing patient education, gel-coated condoms that destroy HIV, HIV vaccinations, and adequately utilizing pre-exposure prophylaxis (PrEP), and post-exposure prophylaxis (PEP). Further development and consistent utilization of innovative prevention tools can significantly reduce the incidence of HIV infections regardless of HIV status.

    HIV-infected pregnant and breastfeeding adolescents are a particularly vulnerable group that require special attention and enhanced support to achieve optimal maternal and infant outcomes. The objective of this paper is to review published evidence about antenatal care (ANC) service delivery and outcomes for HIV-infected pregnant adolescents in low-income country settings, identify gaps in knowledge and programme services and highlight the way forward to improve clinical outcomes of this vulnerable group. Emerging data from programmes in sub-Saharan Africa highlight that HIV-infected pregnant adolescents have poorer prevention of mother-to-child HIV transmission (PMTCT) service outcomes, including lower PMTCT service uptake, compared to HIV-infected pregnant adults. In addition, the limited evidence available suggests that there may be higher rates of mother-to-child HIV transmission among infants of HIV-infected pregnant adolescents. While the reasons for the inferior outcomes among adolescents in ANC need to be further explored and addressed, there is sufficient evidence that immediate operational changes are needed to address the unique needs of this population. Such changes could include integration of adolescent-friendly services into PMTCT settings or targeting HIV-infected pregnant adolescents with enhanced retention and follow-up activities.

    In Jamaica 1-2% of pregnant women are HIV-positive; 876 HIV-positive pregnant women will deliver and at least 283 newly infected HIV-infected infants will be born in 2003; HIV/AIDS is the leading cause of death in children aged one to four years. We describe a collaborative "Town and Gown" programme to address the paediatric and perinatal HIV epidemic in Kingston. A team of academic and government healthcare personnel, comprising paediatricians, obstetricians, public health practitioners, nurses, microbiologists, data management and information technology personnel collaborated to address this public health emergency. A five-point plan was implemented This comprised leadership and training of a core group of paediatric/perinatal HIVprofessionals to serve Greater Kingston and St Catherine and be a model for the rest of Jamaica. Mother-to-child transmission of HIV/AIDS is prevented by counselling and HIV-testing women in the antenatal clinics, giving azidothymidine (AZT) to HIV pregnant women beginning at 28 weeks gestation, throughout labour and to the HIV-exposed infants for the first six weeks of life. A unified parallel programme for identifying the HIV-infected infant and delivering paediatric HIV care at the major paediatric centres was implemented In three years, over 30,000 pregnant women are being tested for HIV; 600 HIV-exposed babies are being identified and about 140 paediatric HIV infections will be prevented The team is building research capacity which emphasizes a strong outcomes-based research agenda and implementation of clinical trials. We are collaborating, locally, regionally and internationally. Collaboratively, the mission of reducing mother-to-child transmission of HIV/AIDS and improving the quality of life for those already living and affected by HIV/AIDS can be achieved.

    This article examines the effect of introducing a new HIV/AIDS service-prevention of mother-to-child transmission of HIV (PMTCT)-on overall quality of prenatal and postnatal care. My results suggest that local PMTCT introduction in Zambia may have actually increased all-cause child mortality in the short term. There is some evidence that vaccinations may have declined in the short term in association with local PMTCT introduction, suggesting that the new service may have partly crowded out existing pediatric health services.

    HIV-1 sequencing has been used extensively in epidemiologic and forensic studies to investigate patterns of HIV-1 transmission. However, the criteria for establishing genetic linkage between HIV-1 strains in HIV-1 prevention trials have not been formalized. The Partners in Prevention HSV/HIV Transmission Study (ClinicaITrials.gov NCT00194519) enrolled 3408 HIV-1 serodiscordant heterosexual African couples to determine the efficacy of genital herpes suppression with acyclovir in reducing HIV-1 transmission. The trial analysis required laboratory confirmation of HIV-1 linkage between enrolled partners in couples in which seroconversion occurred. Here we describe the process and results from HIV-1 sequencing studies used to perform transmission linkage determination in this clinical trial. Consensus Sanger sequencing of env (C2-V3-C3) and gag (p17-p24) genes was performed on plasma HIV-1 RNA from both partners within 3 months of seroconversion; env single molecule or pyrosequencing was also performed in some cases. For linkage, we required monophyletic clustering between HIV-1 sequences in the transmitting and seroconverting partners, and developed a Bayesian algorithm using genetic distances to evaluate the posterior probability of linkage of participants sequences. Adjudicators classified transmissions as linked, unlinked, or indeterminate. Among 151 seroconversion events, we found 108 (71.5%) linked, 40 (26.5%) unlinked, and 3 (2.0%) to have indeterminate transmissions. Nine (8.3%) were linked by consensus gag sequencing only and 8 (7.4%) required deep sequencing of env. In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner, illustrating the relevance of these methods in the design of future HIV-1 prevention trials in serodiscordant couples. A hierarchy of sequencing techniques, analysis methods, and expert adjudication contributed to the linkage

    Youth carry the highest incidence of HIV infection in the United States. Understanding adolescent and young adult (AYA) perspectives on HIV transmission risk is important for targeted HIV prevention. We conducted a mixed methods study with HIV-infected and uninfected youth, ages 18-24 years, from Atlanta, GA. We provided self-administered surveys to HIV-infected and HIV-uninfected AYAs to identify risk factors for HIV acquisition. By means of computer-assisted thematic analyses, we examined transcribed focus group responses on HIV education, contributors to HIV transmission, and pre-sex HIV status disclosure. The 68 participants had the following characteristics: mean age 21.5 years (standard deviation: 1.8 years), 85% male, 90% black, 68% HIV-infected. HIV risk behaviors included the perception of condomless sex (Likert scale mean: 8.0) and transactional sex (88% of participants); no differences were noted by HIV status. Qualitative analyses revealed two main themes: (1) HIV risk factors among AYAs, and (2) barriers to discussing HIV status before sex. Participants felt the use of social media, need for immediate gratification, and lack of concern about HIV disease were risk factors for AYAs. Discussing HIV status with sex partners was uncommon. Key reasons included: fear of rejection, lack of confidentiality, discussion was unnecessary in temporary relationships, and disclosure negatively affecting the mood. HIV prevention strategies for AYAs should include improving condom use frequency and HIV disclosure skills, responsible utilization of social media, and education addressing HIV prevention including the risks of transactional sex.

    Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased.

    Millions of children are living with HIV in sub-Saharan Africa, and the primary mode of these childhood infections is mother-to-child transmission. While existing interventions can virtually eliminate such transmission, in low- and middle-income settings, only 63 % of pregnant women living with HIV accessed medicines necessary to prevent transmission. In Tanzania, HIV prevalence among pregnant women is 3.2 %. Understanding why HIV-positive women disengage from care during and after pregnancy can inform efforts to reduce the impact of HIV on mothers and young children. Informed by the tenets of Grounded Theory, we conducted qualitative interviews with 40 seropositive postpartum women who had disengaged from care to prevent mother-to-child transmission (PMTCT). Nearly all women described antiretroviral treatment (ART) as ultimately beneficial but effectively inaccessible given concerns related to stigma. Many women also described how their feelings of health and vitality coupled with concerns about side effects underscored a desire to forgo ART until they deemed it immediately necessary. Relatively fewer women described not knowing or forgetting that they needed to continue their treatment regimens. We present a theory of PMTCT disengagement outlining primary and ancillary barriers. This study is among the first to examine disengagement by interviewing women who had actually discontinued care. We urge that a combination of intervention approaches such as mother-to-mother support groups, electronic medical records with same-day tracing, task shifting, and mobile technology be adapted, implemented, and evaluated within the Tanzanian setting.

    Selecting sex partners of the same HIV status or serosorting is a sexual risk reduction strategy used by many men who have sex with men. However, the effectiveness of serosorting for protection against HIV is potentially limited. We sought to examine how men perceive the protective benefits of factors related to serosorting including beliefs about engaging in serosorting, sexual communication, and perceptions of risk for HIV. Participants were 94 HIV negative seroconcordant (same HIV status) couples, 20 HIV serodiscordant (discrepant HIV status) couples, and 13 HIV positive seroconcordant (same HIV status) couples recruited from a large gay pride festival in the southeastern US. To account for nonindependence found in the couple-level data, we used multilevel modeling which includes dyad in the analysis. Findings demonstrated that participants in seroconcordant relationships were more likely to believe that serosorting reduces concerns for condom use. HIV negative participants in seroconcordant relationships viewed themselves at relatively low risk for HIV transmission even though monogamy within relationships and HIV testing were infrequent. Dyadic analyses demonstrated that partners have a substantial effect on an individual's beliefs and number of unprotected sex partners. We conclude that relationship partners are an important source of influence and, thus, intervening with partners is necessary to reduce HIV transmission risks.

    Full Text Available Abstract The potential risk of HIV-1 infection following human bite although epidemiologically insignificant, but it is biologically possible. There are anecdotal reports of HIV transmission by human bites particularly if saliva is mixed with blood. The oral tissues support HIV replication and may serve as a previously unrecognized HIV reservoir. The HIV infected individuals have more viruses in blood than saliva, possibly due to the potent HIV-inhibitory properties of saliva. The case presented here is of a primary HIV infections following a human bite where in the saliva was not blood stained but it got smeared on a raw nail bed of a recipient. The blood and saliva of the source and blood of the recipient showed a detectable viral load with 91% sequence homology of C2-V3 region of HIV gp120 between the two individuals. The recipient did not receive PEP [post exposure prophylaxis] as his family physician was unaware of salivary transmission. The family physician should have taken PEP decision after proper evaluation of the severe and bleeding bite. Hence it is necessary to treat the HIV infected human bites with post exposure prophylaxis.

    Full Text Available Background. Identifying and addressing gaps in the prevention of mother-to-child transmission of HIV (PMTCT is required if South Africa (SA is to achieve targets for eliminating MTCT (eMTCT. Potential PMTCT gaps that increase MTCT risk include late maternal HIV diagnosis, lack of or delayed antiretroviral therapy (ART during pregnancy and breastfeeding, and lack of effective prophylaxis for HIV-exposed infants.Objectives. To investigate, in near real time, PMTCT gaps among HIV-infected infants in three districts of KwaZulu-Natal Province, SA.Methods. Between May and September 2016, PMTCT co-ordinators from eThekwini, uMgungundlovu and uMkhanyakude districts received daily email notification of all HIV polymerase chain reaction (PCR-positive results. Co-ordinators reviewed facility records for each infant to identify gaps in PMTCT care, including maternal age, timing of maternal HIV diagnosis, maternal treatment history and maternal viral load (VL monitoring. Data were submitted via the mobile phone SMS (text message service using Rapid Pro technology and analysed in Stata 14.Results. Data on PMTCT gaps were received for 367 (91.8% of 400 infants with HIV PCR-positive results, within a median time of 12.5 days (interquartile range (IQR 6 - 23. The median maternal age was 25 years (IQR 22 - 30, with 48 teenage mothers (15 - 19 years. The sample size was too small to determine whether there were significant differences in PMTCT gaps between the 48 teenage mothers and 293 older (20 - 34 years mothers. Of the mothers, 220 (60.0% were first diagnosed prior to conception or at their first antenatal care (ANC visit, and 127 (34.6% at or after delivery; 137 (37.3% transmitted HIV to their infants despite receiving >12 weeks of ART. VL results were unavailable for 70.0% of women. Only 41 (17.5% of women known to be HIV-positive during ANC had confirmed virological suppression. No statistically significant differences in PMTCT gaps were observed between

    Women comprise 25% of the US HIV epidemic, with many women of reproductive age. There is a need for providers to address the reproductive needs and desires of women with HIV given that effective antiretroviral therapy has transformed HIV into a chronic disease. This cross-sectional study shows high rates of partner serodiscordance (61%) and moderate HIV disclosure to partners (61%). Patients surveyed reported practitioners discuss condoms (94%) and contraception (71%) more often than pregnancy desire (38%). In our sample, 44% of the surveyed women intended future pregnancy, whereas women who did not intend future pregnancy cited HIV/health and serodiscordance as the most common reasons (56% and 35%, resp.). There was no difference in the knowledge of mother-to-child transmission risk between women who intended or did not intend future pregnancy (p = 0.71). These results underline the need for provider training in reproductive counseling to promote risk reduction and education.

    To gain deeper insight into the epidemiology of HIV-1 transmission in South-East Austria we performed a retrospective analysis of 259 HIV-1 partial pol sequences obtained from unique individuals newly diagnosed with HIV infection in South-East Austria from 2008 through 2014. After quality filtering, putative transmission linkages were inferred when two sequences were ≤1.5% genetically different. Multiple linkages were resolved into putative transmission clusters. Further phylogenetic analyses were performed using BEAST v1.8.1. Finally, we investigated putative links between the 259 sequences from South-East Austria and all publicly available HIV polymerase sequences in the Los Alamos National Laboratory HIV sequence database. We found that 45.6% (118/259) of the sampled sequences were genetically linked with at least one other sequence from South-East Austria forming putative transmission clusters. Clustering individuals were more likely to be men who have sex with men (MSM; pAustria had at least one putative inferred linkage with sequences from a total of 69 other countries. In conclusion, analysis of HIV-1 sequences from newly diagnosed individuals residing in South-East Austria revealed a high degree of national and international clustering mainly within MSM. Interestingly, we found that a high number of heterosexual males clustered within MSM networks, suggesting either linkage between risk groups or misrepresentation of sexual risk behaviors by subjects.

    Full Text Available HIV epidemiology informs prevention trial design and program planning. Nine clinical research centers (CRC in sub-Saharan Africa conducted HIV observational epidemiology studies in populations at risk for HIV infection as part of an HIV prevention and vaccine trial network. Annual HIV incidence ranged from below 2% to above 10% and varied by CRC and risk group, with rates above 5% observed in Zambian men in an HIV-discordant relationship, Ugandan men from Lake Victoria fishing communities, men who have sex with men, and several cohorts of women. HIV incidence tended to fall after the first three months in the study and over calendar time. Among suspected transmission pairs, 28% of HIV infections were not from the reported partner. Volunteers with high incidence were successfully identified and enrolled into large scale cohort studies. Over a quarter of new cases in couples acquired infection from persons other than the suspected transmitting partner.

    Background: HIV continues to be a threat in both developed and developing countries. Pakistan has entered concentrated epidemic from low epidemic stage. The prevalence of HIV is more in at risk population particularly intravenous drug users (IDUs). Studies are required to find out other risk factors contributing to spread of the disease in the general population in order to prevent the spread of disease among general population. Methods: A cross-sectional study was carried out on patients reporting for HIV testing at National HIV/STI Referral Lab, National AIDS Control Program (NACP) from January to December 2011. Results: A total of 345 patients reported to the lab during the study period. The detailed histories of 271 patients were available out of which 131 (48.3%) patients were found to be positive for HIV. Minimum age of patient with HIV was 2 years while maximum age was 64 years. HIV affected those more significantly who had visited abroad (p=0.000) or were IDUs (p=0.000). Extramarital sexual activity, blood transfusion, or any surgical procedure in the past was not found to be significant (p=0.574, p=0.243, p=0.252 respectively). Most of the affected males were drivers (16, 12.2%) by profession. Among them 9 had visited gulf countries and 4 of them were deported from the gulf countries having HIV. Conclusion: Migrant workers are a risk factor for HIV transmission. Policy may be developed to focus on this population who continues to spread HIV among their spouses and children as a result of unawareness about their HIV status and its modes of transmission.

    Full Text Available The current standard of care in Canadian obstetrical practice is to offer pregnant women the opportunity for prenatal investigation to diagnose congenital abnormalities. Prenatal amniocentesis is Canada’s most commonly practiced invasive procedure for the diagnosis of chromosomal and single gene disorders. The potential risk of intrapartum HIV transmission during amniocentesis raises several ethical concerns and limits the availability of prenatal genetic testing for HIV-positive pregnant women. Complete virological suppression with antiretroviral therapy may alleviate the risk of mother-to-child transmission during amniocentesis and increase accessibility of this important diagnostic tool in the HIV-positive population. The present report describes a case involving a 32-year-old HIV-positive pregnant woman whose plasma viral load was undetectable on antiretroviral therapy; she underwent successful prenatal amniocentesis without transmission of HIV to her infant.

    2017-01-01

    HIV-related stigma compromises both HIV prevention and treatment and has recently been described as a barrier to utilization of skilled childbirth services in sub-Saharan Africa. This study uses the 2011 Uganda Demographic Health Survey to estimate the associations between HIV-related stigma, measured both at the individual and community level, and use of facility delivery among women. Consistent with theoretical predictions, higher levels of stigma are associated with reduced likelihood of facility delivery. The negative relationship between stigma and facility delivery is especially pronounced when stigma is measured at the community level, highlighting the importance of understanding the proximate context of HIV-related stigma and its potential effects on behavior. Reducing the stigma of HIV will be critical to achieving the twin goals of reducing overall maternal mortality and preventing mother-to-child HIV transmission.

    Interventions to assist HIV+ persons in disclosing their serostatus to sexual partners can play an important role in curbing rates of HIV transmission among men who have sex with men (MSM). Based on the methods of Pinkerton and Galletly (AIDS Behav 11:698-705, 2007), we develop a mathematical probability model for evaluating effectiveness of serostatus disclosure in reducing the risk of HIV transmission and extend the model to examine the impact of serosorting. In baseline data from 164 HIV+ MSM participating in a randomized controlled trial of a disclosure intervention, disclosure is associated with a 45.0 % reduction in the risk of HIV transmission. Accounting for serosorting, a 61.2 % reduction in risk due to disclosure was observed in serodisconcordant couples. The reduction in risk for seroconcordant couples was 38.4 %. Evidence provided supports the value of serostatus disclosure as a risk reduction strategy in HIV+ MSM. Interventions to increase serostatus disclosure and that address serosorting behaviors are needed.

    Full Text Available Objective: The community-based Prevention of Mother to Child Transmission (PMTCT programme in Trinidad and Tobago offers care and support to HIV-positive (HIV+ pregnant women and their families for their lifetime. This study explored the factors influencing repeat childbearing by PMTCT enrolees. Method: In-depth qualitative interviews were conducted with purposively selected and consenting HIV+ women who enrolled in the PMTCT programme (n = 10 in County Victoria and four healthcare workers (HCWs. Transcribed interviews were analysed and coded using thematic content analysis. Results: Though women desired children and motherhood, some did not intend to conceive fearing HIV, age-related ill-health and vertical transmission. Others had not considered pregnancy and conceived through accident and partners’ disregard for the women’s HIV status, particularly if such partners were inebriated. Partners’ desire for children, especially in new relationships, led to planned pregnancies. Nine of the 10 HIV+ women did not seek family planning advice; the one that did was advised about partner infection but not risk reduction, vertical transmission or reinfection. Though HCWs supported HIV+ women’s reproductive rights, they agreed that HCWs stigmatized and discriminated against HIV+ mothers. Both parties saw the PMTCT programme as an effective programme in vastly reducing HIV transmission from mother to child. Conclusion: The PMTCT programme and family planning services should be integrated with tailored services toward HIV+ women and their partners to help them safely achieve their reproductive goals. Healthcare workers should be given training and skillsets to address stigma and discrimination against persons infected with HIV/AIDS within Trinidad and Tobago’s health workforce.

  16. Nurturing the Continuum of HIV Testing, Treatment and Prevention Matrix Cascade in Reducing HIV Transmission.

    Despite the shift in antiretroviral therapy (ARVs) eligibility cascade from CD4 ≤ 200 to CD4 ≤ 350 to CD4 ≤ 500 mm 3 , HIV related morbidity and mortality continue to escalate annually, as do HIV infections. The new paradigm of treatment for all HIV positives individual irrespective of CD4 count may significantly reduce HIV and related illnesses. The author assumes that all HIV infected partners should be eligible for HIV treatment and care, irrespective of CD4 count. A second assumption is that high risk HIV negative partners have free access to continuum of HIV pre-exposure prophylaxis (PrEP), post exposure prophylaxis (PEP) and other prevention packages. A literature review search was used to extract evidence-based ARVs-HIV treatment and prevention interventions among HIV positives and high risk partners respectively. Only articles published in English and indexed in journal nuclei were used for the study. The information was used to nurture understanding of HIV treatment and prevention approaches as well as HIV incidence multiplier effect among HIV serodiscordant partners. The imputed HIV incident reference was assumed at 1.2 per 100 person-years (2). This was based on the imputation that retention in care, adherence and other predetermined factors are functions of an effective health care delivery system. The model showed a reduced HIV transmission from 1.2 per 100 person-years to 1.032 per 100 person-years in 6 months. The average threshold period of HIV suppressed partners on ARVs to an undetectable level. The combined multiplier protective-effect probability of transmitting HIV from HIV positive partners on ARVs-suppressed viremic load to HIV negative partners on PrEP/PEP-prevention was detected at 86. The model showed a significant reduction in HIV incidence. Placing serodiscordant sexual partners in HIV treatment and prevention plays a significant role in reducing and controlling HIV infection. Therefore, the policy of enrolling all HIV positives

    HIV testing of women in child bearing age is an entry point for preventing mother-to-child transmission of HIV (MTCT). This study aims to identify the proportion of women tested for HIV and to determine factors associated with utilization of HIV testing services among pregnant mothers in primary care settings in northern Ethiopia. A cross sectional study was conducted in 416 pregnant women from four primary care centers between October 2, 2012 and May 31, 2013 in East Gojjam, Ethiopia. The proportion of mothers who tested for HIV was 277(67%). Among mothers who were not tested for HIV, lack of HIV risk perception (n = 68, 49%) was a major self-reported barrier for HIV testing. A multivariable logistic regression analysis showed that those pregnant women who had comprehensive knowledge about MTCT had an Adjusted Odd Ratio (AOR) of 3.73 (95% CI: 1.56, 8.94), having comprehensive knowledge on prevention of mother to child transmission (PMTCT) of HIV an AOR of 2.56 (95% CI: 1.26, 5.19), and a favorable attitude towards persons living with HIV an AOR of 2.42 (95%CI, 1.20, 4.86) were more likely to be tested for HIV. One third of pregnant women had never been tested for HIV until the time of the study. Efforts should be made to improve mother's knowledge about MTCT and PMTCT to increase uptake of HIV testing. Enhancing mother's HIV risk perception to scale up HIV testing in resource limited setting is highly recommended.

    The urogenital tract appears to be the only niche of the human body that shows clear differences in microbiota between men and women. The female reproductive tract has special features in terms of immunological organization, an epithelial barrier, microbiota, and influence by sex hormones such as estrogen. While the upper genital tract is regarded as free of microorganisms, the vagina is colonized by bacteria dominated by Lactobacillus species, although their numbers vary considerably during life. Bacterial vaginosis is a common pathology characterized by dysbiosis, which increases the susceptibility for HIV infection and transmission. On the other hand, HIV infections are often characterized by a disturbed vaginal microbiota. The endogenous vaginal microbiota may protect against HIV by direct production of antiviral compounds, through blocking of adhesion and transmission by ligands such as lectins, and/or by stimulation of immune responses. The potential role of probiotics in the prevention of HIV infections and associated symptoms, by introducing them to the vaginal and gastrointestinal tract (GIT), is also discussed. Of note, the GIT is a site of considerable HIV replication and CD4(+) T-cell destruction, resulting in both local and systemic inflammation. Finally, genetically engineered lactobacilli show promise as new microbicidal agents against HIV. © 2013 Federation of European Microbiological Societies. Published by John Wiley & Sons Ltd.
