RESUMEN

BACKGROUND: Prevention of mother-to-child transmission (PMTCT) of HIV services has become an integral part of antenatal services. Prevention of mother-to-child transmission was introduced in all the regions of Ghana, but mother-to-child transmission (MTCT) continued to increase. OBJECTIVES: To explore and describe midwives' perceptions and attitudes towards PMTCT of HIV services. METHOD: Quantitative research approach and descriptive cross-sectional design were used. The population includes all midwives between the ages of 21 and 60 years who work in antenatal care (ANC) clinics in 11 district hospitals in the Central Region of Ghana where the study was conducted. Forty-eight midwives were interviewed using a census sample process. Data were analysed using the Statistical Package for the Social Sciences version 21. Correlation analysis was performed to find the relationships between the attitudes and the perceptions of the midwives on PMTCT of HIV services. RESULTS: Seventy percent of midwives had positive perceptions of PMTCT of HIV services and 85% had positive attitudes towards the provision of PMTCT of HIV services. Midwives were screening all pregnant women who visited the ANCs and referring those who tested positive to other institutions where they can be monitored. Some of the concerns considered were views on retesting HIV-infected pregnant women throughout their pregnancy. There was a positive correlation between attitudes and perceptions of midwives on PMTCT of HIV services. CONCLUSION: Midwives had positive perceptions and positive attitudes towards the PMTCT of HIV services that they were providing to antenatal attendees. Also, as the attitudes of the midwives towards PMTCT of HIV services improved, their perceptions of PMTCT services also improved.Contribution: Decentralisation of PMTCT of HIV services to community-based health facilities is appropriate to enable sub-district health facilities to test for HIV and provide counselling services to pregnant women.

RESUMEN

Background: The elimination of mother-to-child HIV transmission requires access to HIV testing services (HTS) for pregnant women. In Akwa Ibom, Nigeria, 76% of pregnant women receive antenatal care from traditional birth attendants and may not have access to HIV testing. Objectives: This study examines the contribution of traditional birth attendants and other healthcare workers in community birth centres in improving access to HTS among pregnant women and their HIV-exposed infants. Design: A retrospective cross-sectional study of previously collected programme data at two points in time to evaluate the prevention of mother-to-child transmission (PMTCT) programme. Methods: We assessed programme records before and after introducing an intervention that engaged traditional birth attendants and other healthcare workers in community birth centres to expand access to HTS among pregnant women and their HIV-exposed infants in Akwa Ibom State, Nigeria. Data were abstracted from the programme database for the preintervention period (April 2019 to September 2020) and the intervention period (October 2020 to March 2022). Data abstracted include the number of pregnant women tested for HIV, those diagnosed with HIV, the number of HIV-exposed infants who had samples collected for early infant diagnosis and those diagnosed with HIV. The data were analysed descriptively and inferentially. Results: Before the intervention, 39,305 pregnant women and 2248 HIV-exposed infants were tested for HIV. After the intervention, the number of pregnant women tested increased to 127,005 and the number of HIV-exposed infants tested increased to 2490. Among pregnant women, the postintervention testing increased by 3.2-fold, with community birth centres reporting 63% of all tests. The intervention also resulted in an 11% increase in HIV-exposed infants benefitting from early infant diagnosis with community birth centres reporting 5% of all tests. Of those diagnosed with HIV, 24% of pregnant women and 12% of infants were diagnosed at community birth centres. Conclusion: Community-based HIV testing for pregnant women can reduce mother-to-child transmission and improve early diagnosis and treatment of exposed infants. Collaboration with birth attendants is crucial to ensure testing opportunities are not missed. Prospective research is needed to understand the clinical outcomes of intervention programmes in the community.

RESUMEN

One of the most common routes of chronic hepatitis B virus (HBV) infection is mother-to-child transmission (MTCT). Approximately 6.4 million children under the age of five have chronic HBV infections worldwide. HBV DNA high level, HBeAg positivity, placental barrier failure, and immaturity of the fetal immune are the possible causes of chronic HBV infection. The passive-active immune program for children, which consists of the hepatitis B vaccine and hepatitis B immunoglobulin, and antiviral therapy for pregnant women who have a high HBV DNA load (greater than 2 × 105 IU/ml), are currently two of the most important ways to prevent the transmission of HBV from mother to child. Unfortunately, some infants still have chronic HBV infections. Some studies have also found that some supplementation during pregnancy can increase cytokine levels and then affect the level of HBsAb in infants. For example, IL-4 can mediate the beneficial effect on infants' HBsAb levels when maternal folic acid supplementation. In addition, new research has indicated that HBV infection in the mother may also be linked to unfavorable outcomes such as gestational diabetes mellitus, intrahepatic cholestasis of pregnancy, and premature rupture of membranes. The changes in the immune environment during pregnancy and the hepatotropic nature of HBV may be the main reasons for the adverse maternal outcomes. It is interesting to note that after delivery, the women who had a chronic HBV infection may spontaneously achieve HBeAg seroconversion and HBsAg seroclearance. The maternal and fetal T-cell immunity in HBV infection is important because adaptive immune responses, especially virus-specific CD8 T-cell responses, are largely responsible for viral clearance and disease pathogenesis during HBV infection. Meanwhile, HBV humoral and T-cell responses are important for the durability of protection after fetal vaccination. This article reviews the literature on immunological characteristics of chronic HBV-infected patients during pregnancy and postpartum, blocking mother-to-child transmissions and related immune mechanisms, hoping to provide new insights for the prevention of HBV MTCT and antiviral intervention during pregnancy and postpartum.

RESUMEN

BACKGROUND: Breastfed infants depend on human milk calcium and phosphorus for bone mineral accretion and growth. We reported greater mobilization of bone mineral and delayed skeletal recovery in lactating Ugandan women with HIV initiated on tenofovir-based antiretroviral therapy during pregnancy compared to HIV-uninfected counterparts in the Gumba Study. However, it is unknown if these disruptions in maternal bone metabolism affect milk mineral concentrations. RESEARCH AIM: To compare concentrations and patterns of change in milk calcium and phosphorus between lactating women with and without HIV. METHODS: A longitudinal observational study was conducted to compare milk mineral concentrations between women with HIV receiving tenofovir-based ART and uninfected women in the Gumba Study. Milk collected at 2, 14, 26, and 52 weeks lactation was analyzed for calcium and phosphorus. Sodium and potassium were measured at 2 and 14 weeks to detect sub-clinical mastitis. Differences in milk composition between 84 women with HIV and 81 uninfected women were investigated. RESULTS: Women with HIV had higher milk calcium than uninfected women at 14 weeks. The percent difference was +10.2% (SE = 3.0, p = .008) and there was a tendency to greater values at 2 and 26 weeks. Milk calcium decreased in both groups during lactation (p ≤ .001) but was more pronounced in women with HIV. The magnitude of change within individuals in the 1st year of lactation from 2 to 52 weeks was -28.3% (SE 3.9) versus -16.5% (SE 3.5), p for interaction = .05. Differences in milk phosphorus and calcium-to-phosphorus ratio were smaller and mostly not significant. CONCLUSIONS: Participants with HIV on tenofovir-based antiretroviral therapy had altered milk mineral composition. Studies are needed to investigate mechanisms and health implications for the woman and infant.

RESUMEN

Introduction: countries in sub-Saharan Africa, including Ghana, are disproportionately affected by hepatitis B viral (HBV) infection. In these areas, mother-to-child transmission (MTCT) is an essential mode of HBV transmission. Evidently, timely hepatitis B birth dose vaccination remains an effective preventive intervention against MTCT of HBV. Considering that midwives and physicians are the primary care providers of newborns in Ghana, we sought to examine their preventive practices toward vertical transmission of HBV in the eastern region of Ghana. Methods: a cross-sectional survey was conducted with 126 healthcare providers (HCP; midwives and physicians). The participants were conveniently recruited from one regional hospital and four district hospitals. Statistical significance was set at 0.05 alpha level. Results: the findings indicate that 42.9% (n = 54) of HCPs' prevention of mother to child transmission (PMTCT) practices for hepatitis B were good (X2 = 2.57, p > 0.05). Explicitly, 79% indicated screening all pregnant women for hepatitis B as part of antenatal care (X2 = 41.14, p < 0.001). Additionally, about half of the participants (52.4%) reported providing pre-test counselling (X2 = 0.29, p > 0.05), whereas one-third (33%) reported routinely administering a birth dose of the hepatitis B vaccine to neonates of mothers with hepatitis B (X2 = 14.00, p < 0.001). However, only 37% reported administering the hepatitis B vaccine to newborns within 12 hours of birth (X2 = 9.18, p < 0.01). The binary logistic regression analyses identified training as the only significant predictor of good practice on PMTCT of hepatitis B at the 5% level (Wald = 3.91, p =0.05). Conclusion: given that more than half of the participants in the study area had incorrect PMTCT practices for hepatitis B, it is imperative that a series of workshops on hepatitis B be done for healthcare providers in Ghana. In addition, hepatitis B birth dose vaccine must be incorporated into the ´Expanded Programme on Immunisation´ to remove the cost that acts as a barrier to access.

RESUMEN

Most viruses use several entry sites and modes of transmission to infect their host (parenteral, sexual, respiratory, oro-fecal, transplacental, transcutaneous, etc.). Some of them are known to be essentially transmitted via arthropod bites (mosquitoes, ticks, phlebotomes, sandflies, etc.), and are thus named arthropod-borne viruses, or arboviruses. During the last decades, several arboviruses have emerged or re-emerged in different countries in the form of notable outbreaks, resulting in a growing interest from scientific and medical communities as well as an increase in epidemiological studies. These studies have highlighted the existence of other modes of transmission. Among them, mother-to-child transmission (MTCT) during breastfeeding was highlighted for the vaccine strain of yellow fever virus (YFV) and Zika virus (ZIKV), and suggested for other arboviruses such as Chikungunya virus (CHIKV), dengue virus (DENV), and West Nile virus (WNV). In this review, we summarize all epidemiological and clinical clues that suggest the existence of breastfeeding as a neglected route for MTCT of arboviruses and we decipher some of the mechanisms that chronologically occur during MTCT via breastfeeding by focusing on ZIKV transmission process.

RESUMEN

Pregnant women in Vietnam have a high prevalence of hepatitis B virus (HBV) and low prevalence of human immunodeficiency virus (HIV) and syphilis. This study aims to assess the feasibility and benefit of universal testing for HIV, HBV and syphilis in antenatal care (ANC) services. A pilot project was conducted in the Thai Nguyen province of Vietnam between 2012 and 2014. HIV, HBV and syphilis testing were offered to pregnant women. Interventions to eliminate mother-to child-transmission (MTCT) of the three pathogens were provided to infected mothers and their infants. Descriptive analysis was conducted, and the number of infections averted from integrating hepatitis B tests into ANC was estimated. Testing coverage for HIV, HBV and syphilis for the cohort of pregnant women during the pilot project was 98%. Prevalence of HIV, HBV and syphilis infections in this cohort was 0.14%, 7.8%, and 0.03%, respectively. No infant was infected with HIV or syphilis, while HBV infection was diagnosed in 27 infants (13.9%). An estimated 23 mother to child HBV infections were prevented by integrated interventions. The triple prevention of mother-to-child transmission of HIV, HBV and syphilis is feasible. Investment in the expansion of the integrated approach is required to achieve the goal of eliminating MTCT.

RESUMEN

BACKGROUND: Knowledgeable Health Care Workers (HCWs) are indispensable for the proper management of clients. We investigated retention of HCWs at health facility and retention of knowledge at 18, 24 and 36 months after training and correlates for retention of knowledge at 3rd year. METHODS: A cross-sectional study was conducted among 1000 HCWs, 710 were trained and 290 untrained working at the PMTCT of HIV services in health facilities of the ten regions of Cameroon. A Multiple Choice Questionnaire (MCQ) on HIV management with focus on PMTCT of HIV was used to assess retention of HCWs at the health facility and retention of knowledge. Summary statistics described mean scores for retention of HCWs and retention of knowledge. One-way Analysis of Variance summarized the differences in retention of knowledge over time after training. Correlates for retention of knowledge were investigated by logistic regression analysis. RESULTS: The retention of HCWs at health facilities in PMTCT of HIV services was 85%. Trained HCWs had higher mean scores for retention of knowledge than untrained HCWs, p < 0.001. Knowledge attrition was observed from 18, 24 to 36 months following training. Differences in the mean scores for retention of knowledge were observed between state-owned with private and confessionary health facilities but not among trained HCWs at 18, 24 or 36 months. Highest mean scores for retention of knowledge were observed in District Hospitals, Sub-Divisional Hospitals, and Integrated Health Centres. Correlates for retention of knowledge were: gender, type of health facility, location, longevity at PMTCT services, trained others and had means to apply what was trained to do. CONCLUSION: Retention of trained HCWs at health facilities was high, mean scores for retention of knowledge was average and knowledge attrition was observed over time. This research is critical to understand where interventions may be most effective.

RESUMEN

BACKGROUND: High mother-to-child (MTC) transmission rate of HIV might contribute to the increased pandemic rate. The aim of this study was to identify the knowledge, attitude and practices of health personnel working in maternities in the prevention of MTC transmission of HIV. METHODS: This cross-sectional descriptive study was carried out from 20th February to 30th April, 2017. All health personnel working in the maternity wards were included in this study. The variables recorded included their age, grade, experience (number of year of practice), gender, educational level, health structure and the training in prevention of MTC transmission of HIV. Analyses were done using SPSS 21.0. The Pearson Chi-square test or Fisher's exact test and logistic regression were used for comparison. The level of significance was P < 0.05. RESULTS: A total of 140 health personnel were recruited. Knowledge was insufficient amongst 73 of them (52.1%). The factors significantly associated with sufficient knowledge were midwifery qualification (aOR 9.01, 95% CI 1.82-48.60) and training in prevention of MTC transmission of HIV (aOR 2.23, 95% CI 1.02-4.81). Regarding attitudes, it was negative in 85 practitioners (60.7%). Only those aged ≥33 years were significantly associated with a positive attitude (aOR 2.34, 95% CI 1.14-4.23). As concerns practices, only 32 practitioners (22.9%) had good practices. Only midwives were associated with good practices (aOR 3.23, 95% CI 1.21-9.95). CONCLUSION: Insufficient knowledge, attitude and practices in the prevention of MTC transmission of HIV were observed among the majority of health personnel in the region. This lack of knowledge in prevention can therefore contribute to the rise of the mother-to-child transmission rate of HIV. To reduce this rate, more health personnel should be trained, especially midwives, in the prevention of MTC transmission of HIV. Moreover, deliveries of all women living with HIV should be conducted or at least supervised by trained midwives, especially those of at least 33 years of age.

RESUMEN

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.

RESUMEN

BACKGROUND: Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical transmission of HIV (PVT) service delivery in rural Mozambique, where the vertical transmission rate is 12 %, and (2) assessed the appropriateness for a PBI's intervention and application to PVT. METHODS: We conducted 24 semi-structured interviews with nurses, volunteers, community health workers, and traditional birth attendants about the barriers and promoters they experienced delivering PVT services. We then explored emergent themes in subsequent focus group discussions (n = 7, total participants N = 92) and elicited participant perspectives on PBIs. The ecological motivation-opportunity-ability framework guided our iterative data collection and thematic analysis processes. RESULTS: The interviews revealed that while all health worker cadres were motivated intrinsically and by social recognition, they were dissatisfied with low and late remuneration. Facility-based staff were challenged by factors across the rest of the ecological levels, primarily in the opportunity domain, including the following: poor referral and record systems (work mandate), high workload, stock-outs, poor infrastructure (facility environment), and delays in obtaining patient results and donor payment discrepancies (administrative). Community-based cadres' opportunity challenges included lack of supplies, distance (work environment), lack of incorporation into the health system (administration), and ability challenges of incorrect knowledge (health worker). PBIs based on social recognition and that enable action on intrinsic motivation through training, supervision, and collaboration were thought to have the most potential for targeting improvements in record and referral systems and better integrating community-based health workers into the health system. Concerns about the implementation of incentives included neglect of non-incentivized tasks and distorted motivation among colleagues. CONCLUSIONS: We found that highly motivated health workers encountered severe opportunity challenges in their PVT mandate. PBIs have the potential to address key barriers that facility- and community-based health workers encounter when delivering PVT services, specifically by building upon existing intrinsic motivation and leveraging highly valued social recognition. We recommend a controlled intervention to monitor incentives' effects on worker motivation and non-incentivized tasks to generate insights about the feasibility of PBIs to improve the delivery of PVT services.

RESUMEN

BACKGROUND: Adherence to antiretroviral therapy (ART) is crucial to preventing mother-to-child transmission of human immunodeficiency virus (HIV) and ensuring the long-term effectiveness of ART, yet data are sparse from African routine care programs on maternal adherence to triple ART. METHODS: We analyzed data from women who started ART at 13 large health facilities in Malawi between September 2011 and October 2013. We defined adherence as the percentage of days "covered" by pharmacy claims. Adherence of ≥90% was deemed adequate. We calculated inverse probability of censoring weights to adjust adherence estimates for informative censoring. We used descriptive statistics, survival analysis, and pooled logistic regression to compare adherence between pregnant and breastfeeding women eligible for ART under Option B+, and nonpregnant and nonbreastfeeding women who started ART with low CD4 cell counts or World Health Organization clinical stage 3/4 disease. RESULTS: Adherence was adequate for 73% of the women during pregnancy, for 66% in the first 3 months post partum, and for about 75% during months 4-21 post partum. About 70% of women who started ART during pregnancy and breastfeeding adhered adequately during the first 2 years of ART, but only about 30% of them had maintained adequate adherence at every visit. Risk factors for inadequate adherence included starting ART with an Option B+ indication, at a younger age, or at a district hospital or health center. CONCLUSIONS: One-third of women retained in the Option B+ program adhered inadequately during pregnancy and breastfeeding, especially soon after delivery. Effective interventions to improve adherence among women in this program should be implemented.

RESUMEN

Hepatitis B, a serious infectious disease caused by the hepatitis B virus (HBV), remains a worldwide social and public health problem. Hepatitis B has a particularly high incidence rate in the world, whereas approximately 35-50% HBV carriers are infected through vertical transmission. Even after newborn immunoprophylaxis, vertical transmission still accounts for 5-10% in China according to plenty of literature in Chinese language. For these reasons, it is important to determine how to effectively intervene in mother-to-child transmission (MTCT). To date, though, intervention methods and measures remain controversial. In order to understand the mechanism of MTCT intervention further and develop effective preventions and interventions, a comprehensive analysis and presentation on some of its more controversial issues will be given in this paper. And eventually we conclude three measures and strategies for these issues: (1) emancipate the mind and seek truth from facts to understand the controversial issues pertaining to MTCT of HBV; (2) treat the basic rules and changing characteristics of MTCT blocking process of hepatitis B with holistic medical thought dialectically and (3) further explore the interaction of genetic susceptibility and environmental factors of MTCT of hepatitis B.

RESUMEN

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.

RESUMEN

The World Health Organization's (WHO) Strategic Framework for the Elimination of New HIV Infections among Children in Africa by 2015 identifies important synergies for the elimination of mother-to-child transmission of HIV and syphilis in terms of prevention interventions, implementation logistics and service delivery, monitoring and evaluation systems, and need for sustained political commitment. The WHO advocates the use of an integrated, rights-based dual approach with partnerships and collaboration to make the best use of available resources. Through a consultative approach, six countries in the African Region committed to dual elimination and developed and implemented action plans for this purpose. Where interest and commitment are high, this may also be possible and effective in other African countries.

RESUMEN

Although advances in HIV prevention and treatment suggest the possibility of creating an AIDS-free generation, many areas of the world still suffer from high rates of mother-to-child transmission (MTCT) of HIV. Interventions proven to significantly decrease rates of MTCT of HIV are often unavailable in resource-limited settings due to lack of reliable clean water, low numbers of hospital deliveries and inconsistent availability of antiretroviral medications. Vitamin A, with its multiple roles in epithelial, reproductive and immune function, has been evaluated as a possible intervention for preventing MTCT. Early observational studies suggested an association between vitamin A deficiency and increased rates of MTCT of HIV; however, the controlled studies that followed did not find a benefit for vitamin A in decreasing MTCT rates. Although vitamin A has some benefits for infants postpartum, it is not recommended for the reduction of the risk of MTCT of HIV.

RESUMEN

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.

RESUMEN

BACKGROUND/AIMS: Retaining patients in prevention of mother-to-child transmission of HIV studies can be challenging in resource-limited settings, where high lost to follow-up rates have been reported. In this article, we describe the effectiveness of methods used to encourage retention in the Breastfeeding, Antiretrovirals, and Nutrition study and analyze factors associated with lost to follow-up in the study. METHODS: The Breastfeeding, Antiretrovirals, and Nutrition clinical trial was designed to evaluate the efficacy of three different mother-to-child HIV transmission prevention strategies. Lower than expected participant retention prompted enhanced efforts to reduce lost to follow-up during the conduct of the trial. Following study completion, we employed regression modeling to determine predictors of perfect attendance and variables associated with being lost to follow-up. RESULTS: During the study, intensive tracing efforts were initiated after the first 1686 mother-infant pairs had been enrolled, and 327 pairs were missing. Of these pairs, 60 were located and had complete data obtained. Among the 683 participants enrolling after initiation of intensive tracing efforts, the lost to follow-up rate was 3.4%. At study's end, 290 (12.2%) of the 2369 mother-infant pairs were lost to follow-up. Among successfully traced missing pairs, relocation was common and three were deceased. Log-binomial regression modeling revealed higher maternal hemoglobin and older maternal age to be significant predictors of perfect attendance. These factors and the presence of food insecurity were also significantly associated with lower rates of lost to follow-up. CONCLUSION: In this large HIV prevention trial, intensive tracing efforts centered on reaching study participants at their homes succeeded in finding a substantial proportion of lost to follow-up participants and were very effective in preventing further lost to follow-up during the remainder of the trial. The association between food insecurity and lower rates of lost to follow-up is likely related to the study's provision of nutritional support, including a family maize supplement, which may have contributed to patient retention.

RESUMEN

INTRODUCTION: Access to lifesaving prevention of mother-to-child transmission (PMTCT) services is problematic in rural Zambia. The simplest intervention used in Zambia has been 2-dose nevirapine (NVP) administration in the peripartum period, a regimen of 1 NVP tablet to the mother at the onset of labor and 1 dose in the form of syrup to the newborn within 4 to 72 hours after birth. This 2-dose regimen has been shown to reduce MTCT by nearly 50%. We set out to demonstrate that in-home HIV testing and NVP dosing by traditional birth attendants (TBAs) is feasible and acceptable by women in rural Zambia. METHODS: This was a pilot program using TBAs to perform rapid saliva-based HIV testing and administer single-dose NVP in tablet form to the mother at the onset of labor and syrup to the infant after birth. RESULTS: A total of 280 pregnant women were consented and enrolled into the program, of whom 124 (44.3%) gave birth at home with the assistance of a trained TBA. Of those, 16 (12.9%) were known to be HIV positive, and 101 of the remaining 108 (93.5%) accepted a rapid HIV test. All these women tested HIV negative. In the subset of 16 mothers who were HIV positive, 13 (81.3%) took single-dose NVP administered by a TBA between 1 and 24 hours prior to birth and 100% of exposed newborns (16 of 16) received NVP syrup within 72 hours after birth, 80% of whom were dosed in the first 24 hours of life. DISCUSSION: With the substantial shortage of human resources in public health care throughout sub-Saharan Africa, it is extremely valuable to utilize lay health care workers to help extended services beyond the level of the facility. Given the high uptake of PMTCT services we believe that TBAs with proper training and support can successfully provide country-approved PMTCT.
