Patient factors to target for elimination of mother-to-child transmission of HIV

Using the Family Planning Estimation Tool (FPET) to assess national-level family planning trends and future projections for contraceptive prevalence and associated demand for HIV-infected women in sub-Saharan Africa

The combination of low uptake of modern contraceptives, high rates of unintended pregnancies, and the pervasive HIV epidemic in Sub-Saharan Africa (SSA) poses a threat to maternal, newborn, and child health in the region. This study examined the prevalence, need, and demand satisfied by modern contraceptive methods for women who tested positive for HIV (both unmarried and married) in 10 countries in SSA. We used the Family Planning Estimation Tool (FPET) to generate national-level trends and projections from 1983 through 2030. Individual-level data from 30 DHS surveys conducted between 2004 and 2018 in 10 sub-Saharan Africa (SSA) countries were used to produce projections for 1) all women and 2) unmarried and married women who tested positive for HIV. Throughout the period, Ethiopian and Guinean women who tested positive for HIV had a higher %mCPR (utilization of modern family planning methods) vis-à-vis all women. Among women who tested positive for HIV, the highest percentage of family planning demand satisfied by modern methods was observed in Zimbabwe (85.27, CI: 76.32-91.69), Lesotho (82.75, CI: 71.80-89.86), Rwanda (80.17, CI: 70.01-87.62), Malawi (73.11, CI: 61.50-82.63), and Zambia (72.63, CI: 64.49-80.09). The highest unmet need for modern contraceptives was found in Senegal (25.38, CI:18.36-33.72), followed by Cameroon (23.59, CI:19.30-28.59) and Sierra Leone (23.16, CI:16.64-32.05). Zimbabwe had the lowest unmet need (10.61, CI:6.36-16.13) and achieved the highest change in %mCPR (49.28, SE:6.80). Among married women who tested positive for HIV, their unmet need for modern contraception will remain higher in 2030. Continuing existing policies until 2030 would result in significant coverage gain among married vis-à-vis unmarried women who tested positive for HIV. Our projections emphasize the importance of country-specific strengthening initiatives, programs, and services targeting unmarried women.

Assessment of the effect of pre-conception care on preventing mother-to-child transmission of HIV in Nyeri County

Introduction

the provision of essential preconception care services for HIV-positive pregnant women is crucial to prevent HIV transmission to infants. This includes pregnancy intention screening services, adequate viral load monitoring and suppression before conception, and necessary nutritional support. In Nyeri County, the prevalence of Mother-to-Child Transmission (MTCT) of HIV is 5.3%, which is higher than the global threshold of 5%. This study aims to evaluate the impact of pre-conception care services in preventing HIV transmission to infants in Nyeri County. The study objectives are to assess the utilization of pre-conception care services among HIV-positive women, specifically focusing on pregnancy intention screening, viral load monitoring and suppression, and access to nutritional assessment services before pregnancy. Additionally, the study aims to investigate the relationship between the provision of pre-conception care services and infant HIV outcomes.

Methods

this cross-sectional retrospective descriptive study employed stratified sampling to select eight level 4 and level 5 hospitals in Nyeri County. The target population consisted of HIV-infected women seeking postnatal care in these facilities, with a sample size of 252 women who had HIV-exposed infants under two years old and were receiving post-natal care at the respective hospitals. Sociodemographic characteristics, including age, marital status, and education level, were collected. Data analysis involved both descriptive and inferential statistics.

Results

our findings revealed that only 34.2% of HIV-positive women seeking postnatal care had received information or services related to pregnancy intention screening, a crucial aspect of pre-conception care. Almost half (46.4%) of the women who participated in the study had undergone viral load measurements before pregnancy, which is another critical component of preconception care. Additionally, 85.6% of these women had received nutritional services during pregnancy from their healthcare providers. Interestingly, all women who received any pre-conception care services reported that their infants were alive and tested HIV-negative.

Conclusion

preconception care is crucial in preventing mother-to-child transmission of HIV. Efforts should be made to ensure that all HIV-infected women planning to conceive have access to preconception care services.

Mixed-methods cross-sectional study of the prevention of vertical HIV transmission program users unaware of male partner's HIV status, in six South African districts with a high antenatal HIV burden

BACKGROUND

Elimination of vertical HIV Transmission (VHT) and maternal deaths are global health priorities. Male involvement is one of the most important factors that influences women's decisions, including the uptake of Prevention of vertical HIV transmission (P-VHT). We sought to understand not knowing a male partner's HIV status (MPHIVs) amongst women using services to prevent vertical HIV transmission in six South African districts with high antenatal HIV burden.

METHODS

A mixed-methods cross-sectional study was conducted in six South African districts, and data collected through face-to-face interviews with women and focus group discussions (FGDs) with women or male partners. The quantitative data were analyzed using STATA SE-17.0 and an inductive approach was used for qualitative data analysis.

RESULTS

Overall, 28.7% of women were unaware of their MPHIVs, while 25.3% and 46.0% knew the MPHIVs was positive or negative, respectively. In multivariable logistic regression, single marital status and unplanned pregnancy increased the odds of not knowing a MPHIVs while a woman's disclosure of her HIV status to the male partner reduced the odds. FDGs highlighted complexities around MPHIVs disclosure, e.g., reluctance to test for HIV and potential interventions including healthcare worker (HCW) assisted HIV disclosure.

CONCLUSION

User-informed interventions to address MPHIVs non-disclosure amongst women of child-bearing age, particularly those at risk of unstable sexual partners and unplanned pregnancies, should be strengthened.

Contraceptive implant use duration is not associated with breakthrough pregnancy among women living with HIV and using efavirenz: a retrospective, longitudinal analysis

Introduction

Contraceptive implants containing etonogestrel and levonorgestrel have emerged as popular contraceptive options among women in areas of high HIV burden in sub‐Saharan Africa. However, recent pharmacokinetic data have shown drug–drug interactions between implants and efavirenz‐containing antiretroviral therapy (ART), reducing the effectiveness of the implants. Here, we evaluated pregnancy incidence in 6‐month intervals following implant initiation among women using efavirenz and contraceptive implants to assess whether the risk of breakthrough pregnancy is higher after specific periods of implant use.

Methods

We used data from a retrospective longitudinal analysis of women living with HIV ages 18–45 years in western Kenya who attended HIV‐care facilities between 2011 and 2015. We used Cox proportional hazard models to compute hazard ratios (HRs) for breakthrough pregnancy by implant type and ART regimen. Depending on the model, we adjusted for socio‐demographic and clinical factors, programme, site and interaction between calendar time and ART regimen. We utilized inverse probability weights (IPWs) to account for three sampling phases (electronic medical record [EMR], chart review and phone interview) and calculated overall parameter estimates.

Results

Women contributed 14,768 woman‐years from the largest sampling phase (EMR). The median age was 31 years. Women used etonogestrel implants for 26–69% of the time and levonorgestrel implants for 7–31% of the time, depending on the sampling phase. Women used efavirenz, nevirapine or no ART for 27–33%, 40–46% and 15–26% of follow‐ups, respectively. When combining sampling phases, there was little evidence to suggest that the relative hazard of pregnancy among efavirenz‐containing ART users relative to nevirapine‐containing ART changed with length of time on implants: IPW‐adjusted HR of 3.1 (CI: [1.5; 6.4]) at 12 months, 3.4 (CI: [1.8; 6.3]) at 24 months, 3.8 (CI: [1.9; 7.7]) at 36 months and 4.2 (CI: [1.6; 11.1]) at 48 months (interaction p‐value = 0.88). Similarly, no significant change in HRs over time was found when comparing women not using ART to nevirapine‐containing ART users (interaction p‐value = 0.49).

Conclusions

We did not find evidence to suggest implants being more fallible from drug–drug interactions with efavirenz at later time intervals of implant use. Thus, we would not recommend shortening the duration of implant use or replacing implants sooner when concomitantly used with efavirenz.

Male partner unknown HIV status as a risk factor for HIV incidence and clinical outcomes in prevention of mother-to-child transmission of HIV programmes in 21 WHO priority countries: a systematic review protocol

INTRODUCTION

Research has shown an association between increased disclosure of HIV status by pregnant and breastfeeding women and improved clinical health and that of their infant. Increasing awareness about their male partner's HIV status will no doubt lead to even better outcomes at the population level. Male partner involvement is important for improving outcomes of prevention of mother-to-child transmission of HIV (MTCT) as it improves social support and commitment from both parents of the baby to ensure sustained good health. Although lack of knowledge of the HIV status of a male partner is of great concern, limited research has been done to determine whether it remains one of the barriers to reaching the proposed goals of eliminating MTCT in pregnant or postpartum women. Our aim is to determine if lack of knowledge of a male partner's HIV status is a significant risk factor for HIV incidence and poor HIV clinical outcomes among pregnant women and postpartum women and their infants.

METHODS AND ANALYSIS

A systematic review and meta-analysis of experimental and observational studies will be conducted. The review will focus on knowledge of male partner's HIV status in the 21 priority countries most affected by HIV in Africa. We will search electronic databases such as PubMed/Medline, Scopus, Web of Science and Cochrane library, Science Direct, CINAHL, LILACS and SciELO databases from January 2011 to December 2021. We will also search the Pan African and WHO clinical trial registries and conference archives. We will conduct a quality assessment of eligible studies and evaluate the heterogeneity of the pooled studies using the I ² statistic. The statistical analysis will be performed using STATA statistical software V.16.

ETHICS AND DISSEMINATION

The study will use publicly available data and ethics exemption has been obtained from Human Research Ethics Committees, Faculty of Medicine & Health Sciences, Stellenbosch University. The protocol was registered on Prospective Register of Systematic Reviews, registration number CRD42021247686, in May 2021. Findings of this systematic review will be disseminated in peer-review journals including various media platforms, that is, webinars, symposia, conferences or congresses.

Determinants of HIV infection among children born from mothers on prevention of mother to child transmission programme of HIV in southern Ethiopia: a case-control study

OBJECTIVE

This study was aimed to identify determinants of HIV infection among children born from mothers on the prevention of mother to child transmission (PMTCT) programme in Southern Ethiopia. It was designed to explore the main contributors to the considerable transmission rate of HIV from mother to child.

SETTING AND DESIGN

A multicentre facility-based unmatched case-control study was conducted using 27 health facilities providing PMTCT service in Southern Ethiopia.

PARTICIPANTS

Out of 307 (62 cases and 245 controls) expected to participate in this study, a total of 290 mother-child pairs of 58 cases and 232 controls have completed the interview. Cases were children born to mothers on PMTCT programme and with DNA PCR or antibody HIV positive test result at ≤24 months of age. Controls were children born to mothers on PMTCT programme and with DNA PCR or antibody HIV negative test result at ≤24 months of age.

RESULT

Data were collected from the mother and record and analysed using SPSS V.20. Logistic regression analysis was done for statistical association and the significance of association was declared at a p value of <0.05. Rural residence (adjusted OR (AOR): 4.15, 95% CI: (1.57 to 10.97)), knowing serostatus during current pregnancy (AOR: 5.11, 95% CI: (1.33 to 19.69)), home delivery (AOR: 6.00, 95% CI: (2.310 to 15.593)), poor partner involvement (AOR: 5.95, 95% CI: 1.91 to 18.53)), poor adherence, late enrolment of the child for ARV prophylaxis (AOR: 4.89, 95% CI: 1.34 to 17.88)), mixed breastfeeding practice (AOR: 10.36, 95% CI: (3.10 to 34.60)) and failure to be on cotrimoxazole therapy (AOR: 7.56, 95% CI: 2.07 to 27.61)) were factors significantly associated with MTCT.

CONCLUSION

The finding implies that more needs to be done on rural residents, strengthening screening for HIV before pregnancy, encouraging male involvement, early enrolment of child for ARV prophylaxis, avoiding mixed breast feeding and putting newborn on cotrimoxazole therapy.

Attitudes Toward Pregnancy Among Women Enrolled in Prevention of Mother-to-Child Transmission of HIV (PMTCT) Services in Moshi, Tanzania

For pregnant women living with HIV (WLWH), feelings about pregnancy may influence their emotional well-being and health seeking behaviors. This study examined attitudes toward pregnancy and associated factors among women enrolled in prevention of mother-to-child transmission of HIV (PMTCT) services in Moshi, Tanzania. 200 pregnant WLWH were enrolled during their second or third trimester of pregnancy and completed a structured survey. Univariable and multivariable regression models examined factors associated with attitudes toward pregnancy, including demographics, interpersonal factors, and emotional well-being. Attitudes toward the current pregnancy were generally positive, with 87% of participants reporting feeling happy about being pregnant. In the final multivariable model, having higher levels of partner support, being newly diagnosed with HIV, and having fewer children were significantly associated with more positive attitudes toward their pregnancy. Findings point to a need for tailored psychosocial support services in PMTCT, as well as comprehensive reproductive health care for WLWH.

Profile of Young South African Children Hospitalized With HIV: Cause for Concern

We describe the history of mother-to-child-prevention, time to HIV diagnosis and antiretroviral therapy of 55 hospitalized HIV-positive children (median age, 5.7 months). Of 31 (56%) mothers who knew their HIV status prior to pregnancy, 11 (35%) did not attend antenatal clinics; those who did attend had poor viral suppression. Despite rapid recognition and access to treatment, 13% of hospitalized HIV-positive infants died. Strategies to reach the mothers driving vertical transmission are imperative.

Filling the gaps in the Peruvian care continuum for HIV-infected pregnant mothers: a case-control study in metropolitan Lima-Callao, Peru

Mother-to-child transmission of HIV (MTCT) accounts for a significant proportion of new HIV infections in Peru. The purpose of this case-control study was to examine maternal and infant factors associated with MTCT in Peru from 2015 to 2016. For each biologically confirmed case infant, we randomly selected four birth year- and birth hospital-matched controls from five hospitals in Lima-Callao. Maternal and infant information were gathered from medical records. Simple conditional logistic regression was utilized to examine possible maternal and infant characteristics associated with MTCT. The rate of MTCT was 6.9% in 2015 and 2.7% in 2016. A total of 63 matched controls were identified for 18 cases. Protective factors included higher number of prenatal visits (odds ratio [OR]: 0.72; 95% confidence interval [CI]: 0.55-0.94, p = 0.012) and having more children (OR: 0.10, 95% CI: 0.01-0.79, p = 0.029). Risk factors included later maternal diagnosis (OR: 1.19; 95% CI: 1.06-1.34; p = 0.001) and greater viral load at the time of maternal diagnosis (OR: 1.05; 95% CI: 1.01-1.10; p = 0.022). Our study highlights the importance of targeting early and continued prenatal care as specific areas to target to prevent gaps in the HIV treatment cascade for pregnant HIV-infected women. These strategies can ensure early screening and initiation of antiretroviral therapy to reduce MTCT rates.

HIV viraemia during pregnancy in women receiving preconception antiretroviral therapy in KwaDukuza, KwaZulu-Natal

BACKGROUND

Preconception antiretroviral therapy (PCART) followed by sustained viral suppression is effective in preventing mother-to-child transmission of HIV. The rates of persistent and transient viraemia in such patients have not been prospectively assessed in South Africa.

OBJECTIVES

We determined the prevalence of transient and persistent viraemia in HIV-positive women entering antenatal care on PCART and studied variables associated with viraemia.

METHODS

We performed a prospective cross-sectional observational study of HIV-positive pregnant women presenting to a primary healthcare facility in KwaZulu-Natal. All had received at least 6 months of first-line PCART. Viral load (VL) was measured, patients were interviewed, adherence estimated using a visual analogue scale and adherence counselling provided. Viral load was repeated after 4 weeks where baseline VL exceeded 50 copies/mL.

RESULTS

We enrolled 82 participants. Of them, 59 (72%) pregnancies were unplanned. Fifteen participants (18.3%) were viraemic at presentation with VL > 50 copies/mL. Of these, seven (8.5%) had viral suppression (VL < 50 copies/mL), and eight remained viraemic at the second visit. Adherence correlated significantly with viraemia at baseline. Level of knowledge correlated with adherence but not with lack of viral suppression at baseline. Socio-economic indicators did not correlate with viraemia. No instances of vertical transmission were observed at birth.

CONCLUSIONS

Approximately 20% of women receiving PCART may demonstrate viraemia. Half of these may be transient. Poor adherence is associated with viraemia, and efforts to encourage and monitor adherence are essential. The rate of unplanned pregnancies is high, and antiretroviral therapy programmes should focus on family planning needs of women in the reproductive age group to prevent viral non-suppression prior to pregnancy.

Long-term effects of unintended pregnancy on antiretroviral therapy outcomes among South African women living with HIV

OBJECTIVE

Unintended pregnancies are common among women living with HIV, but there are no data on their long-term impact on treatment outcomes. In a cohort of women initiating antiretroviral therapy (ART) during pregnancy, we examined the association between the intendedness of the current pregnancy, measured antenatally, and elevated viral load up to 5 years postpartum.

DESIGN

Prospective study with enrolment at entry into antenatal care and follow-up at study visits separate from routine care.

METHODS

At enrolment women completed the London Measure of Unplanned Pregnancy. Mixed effects models examined the impact of the intendedness of the pregnancy (planned versus each of unplanned or ambivalent, respectively) on viral load 50 or more copies/ml across postpartum study visits.

RESULTS

Overall, 459 women were followed for a median of 43 months postpartum, contributing 2535 viral load measures (median per woman: 6). Ambivalent and unplanned pregnancy were commonly reported (20 and 60%, respectively), and the proportion of women with elevated viral load increased over time (16% at 6 weeks to 43% by 36-60 months postpartum). Compared with those reporting a planned pregnancy, elevated viral load was more common among women reporting an unplanned pregnancy (odds ratio: 2.87; 95% confidence interval: 1.46-5.64), with a trend towards a higher odds among those reporting ambivalence (odds ratio: 2.19; 95% confidence interval: 0.97-4.82); associations persisted after adjustment for a wide range of demographic, clinical and psychosocial factors.

CONCLUSION

These novel data suggest that unplanned pregnancy may be a prevalent and persistent predictor of poor ART outcomes among women initiating ART during pregnancy.

Diagnosis of Human Immunodeficiency Virus Infection

HIV diagnostics have played a central role in the remarkable progress in identifying, staging, initiating, and monitoring infected individuals on life-saving antiretroviral therapy. They are also useful in surveillance and outbreak responses, allowing for assessment of disease burden and identification of vulnerable populations and transmission "hot spots," thus enabling planning, appropriate interventions, and allocation of appropriate funding. HIV diagnostics are critical in achieving epidemic control and require a hybrid of conventional laboratory-based diagnostic tests and new technologies, including point-of-care (POC) testing, to expand coverage, increase access, and positively impact patient management. In this review, we provide (i) a historical perspective on the evolution of HIV diagnostics (serologic and molecular) and their interplay with WHO normative guidelines, (ii) a description of the role of conventional and POC testing within the tiered laboratory diagnostic network, (iii) information on the evaluations and selection of appropriate diagnostics, (iv) a description of the quality management systems needed to ensure reliability of testing, and (v) strategies to increase access while reducing the time to return results to patients. Maintaining the central role of HIV diagnostics in programs requires periodic monitoring and optimization with quality assurance in order to inform adjustments or alignment to achieve epidemic control.

Determinants of HIV infection among children born to mothers on prevention of mother to child transmission program of HIV in Addis Ababa, Ethiopia: a case control study

BACKGROUND

Despite wide spread use of Antiretroviral Therapy (ART) by pregnant women living with Human Immunodeficiency Virus (HIV), the transmission rate is still higher by 18% after breastfeeding ends. The aim of this study was to identify factors affecting mother-to-child HIV transmission.

METHODS

Unmatched case-control study was conducted in Addis Ababa, from April to May, 2017. A case was HIV positive mother who had been on PMTCT program with her child confirmed HIV positive at or before 24 months and control was HIV positive mother who had been on PMTCT program with her child tested definitive HIV negative at 24 months. Accordingly, 44 cases were identified and for each case four controls with the nearest date of birth to the cases were selected from same health facilities. Primary data collected from the mothers were supplemented by record reviews and entered to Epidata version 3.1 and analyzed using SPSS version 22. Multivariate logistic regression was fitted to identify factors independently associated with mother-to-child HIV transmission.

RESULTS

Lack of participation in mother-to-mother support program (AOR: 5.1; 95% CI: 1.4, 18.1), low partner involvement (AOR: 6.9; 95% CI: 1.4, 13.4), poor ART adherence (AOR:3.1; 95% CI: 1.3, 7.5), positive syphilis test results (AOR: 3.2; 95% CI: 1.2, 8.6), maternal malnutrition (AOR: 3.1; 95% CI: 1.4, 6.8), unplanned pregnancy (AOR: 10.3; 95% CI: 3.9, 27.2), home delivery (AOR: 5.3; 95% CI: 1.4, 19.4) and mixed feeding of the child during first six months of life (AOR: 12.5; 95% CI: 2.9, 52.7) were significantly associated with MTCT of HIV.

CONCLUSIONS

Mother-to-mother support, male partner involvement in PMTCT of HIV, strengthening antenatal care, counseling mothers on appropriate infant feeding options are important to reduce mother -to- child transmission of HIV.

Impact of Birth HIV-PCR Testing on the Uptake of Follow-up Early Infant Diagnosis Services in Cape Town, South Africa

INTRODUCTION

Polymerase chain reaction testing at birth ("birth-testing") is suggested by new World Health Organization guidelines for rapid diagnosis of infants infected with HIV in utero. However, there are few data on the implementation of this approach in sub-Saharan Africa, and whether birth testing affects uptake of subsequent routine early infant diagnosis (EID) testing at 6-10 weeks of age is unknown.

METHODS

We reviewed 575 consecutive infants undergoing targeted high-risk birth testing in Cape Town, South Africa, and matched those testing HIV negative at birth (n = 551) to HIV-exposed infants who did not receive birth testing (n = 551). Maternal and infant clinical and demographic data, including EID testing uptake, were abstracted from routine records.

RESULTS

Overall, 3.8% of all birth tests conducted were positive while later EID testing positivity rates were 0.5% for those infants testing HIV negative at birth and 0.4% for those without birth testing. Infants who underwent birth testing were less likely to present for later EID compared with those without a birth test (73% vs. 85%; P < 0.001). This difference persisted after adjusting for maternal and infant characteristics (adjusted odds ratio, 0.60; 95% confidence interval: 0.41-0.86) and across demographic and clinical subgroups. Infants undergoing birth testing also presented for later EID at a significantly older age (mean age, 60 vs. 50 days; P < 0.001).

CONCLUSIONS

While the yield of targeted high-risk birth testing in this setting appears high, neonates testing HIV negative at birth may be less likely to present for subsequent EID testing. For birth testing implementation to contribute to overall EID program goals, structured interventions are required to support follow-up EID services after negative birth test results.

PMTCT Service Uptake Among Adolescents and Adult Women Attending Antenatal Care in Selected Health Facilities in Zimbabwe

Background:

Age-disaggregated analyses of prevention of mother-to-child transmission (PMTCT) program data to assess the uptake of HIV services by pregnant adolescent women are limited but are critical to understanding the unique needs of this vulnerable high-risk population.

Methods:

We conducted a retrospective analysis of patient-level PMTCT data collected from 2011 to 2013 in 36 health facilities in 5 districts of Zimbabwe using an electronic database. We compared uptake proportions for PMTCT services between adolescent (≤19 years) and adult (>19 years) women. Multivariable binomial regression analysis was used to estimate the association of the women's age group with each PMTCT service indicator.

Results:

The study analyzed data from 22,215 women aged 12–50 years (22.5% adolescents). Adolescents were more likely to present to antenatal care (ANC) before 14 weeks of gestational age compared with older women [adjusted relative risk (aRR) = 1.34; 95% confidence interval: 1.22 to 1.47] with equally low rates of completion of 4 ANC visits. Adolescents were less likely to present with known HIV status (aRR = 0.34; 95% confidence interval: 0.29 to 0.41) but equally likely to be HIV tested in ANC. HIV prevalence was 5.5% in adolescents vs 20.1% in adults. While >84% of both HIV-positive groups received antiretroviral drugs for PMTCT, 44% of eligible adolescents were initiated on antiretroviral therapy vs 51.3% of eligible adults, though not statistically significant.

Conclusions:

Pregnant adolescents must be a priority for primary HIV prevention services and expanded HIV treatment services among pregnant women to achieve an AIDS-free generation in Zimbabwe and similar high HIV burden countries.

Growing inequities in maternal health in South Africa: a comparison of serial national household surveys

BACKGROUND

Rates of maternal mortality and morbidity vary markedly, both between and within countries. Documenting these variations, in a very unequal society like South Africa, provides useful information to direct initiatives to improve services. The study describes inequalities over time in access to maternal health services in South Africa, and identifies differences in maternal health outcomes between population groups and across geographical areas.

METHODS

Data were analysed from serial population-level household surveys that applied multistage-stratified sampling. Access to maternal health services and health outcomes in 2008 (n = 1121) were compared with those in 2012 (n = 1648). Differences between socio-economic quartiles were quantified using the relative (RII) and slope (SII) index of inequality, based on survey weights.

RESULTS

High levels of inequalities were noted in most measures of service access in both 2008 and 2012. Inequalities between socio-economic quartiles worsened over time in antenatal clinic attendance, with overall coverage falling from 97.0 to 90.2 %. Nationally, skilled birth attendance remained about 95 %, with persistent high inequalities (SII = 0.11, RII = 1.12 in 2012). In 2012, having a doctor present at childbirth was higher than in 2008 (34.4 % versus 27.8 %), but inequalities worsened. Countrywide, levels of planned pregnancy declined from 44.6 % in 2008 to 34.7 % in 2012. The RII and SII rose over this period and in 2012, only 22.4 % of the poorest quartile had a planned pregnancy. HIV testing increased substantially by 2012, though remains low in groups with a high HIV prevalence, such as women in rural formal areas, and from Gauteng and Mpumalanga provinces. Marked deficiencies in service access were noted in the Eastern Cape ad North West provinces.

CONCLUSIONS

Though some population-level improvements occurred in access to services, inequalities generally worsened. Low levels of planned pregnancy, antenatal clinic access and having a doctor present at childbirth among poor women are of most concern. Policy makers should carefully balance efforts to increase service access nationally, against the need for programs targeting underserved populations.

HIV in Pregnancy

In the United States, women with HIV have the ability to make informed choices relating to their reproductive lives more now than ever before. The increasing availability of antiretroviral therapy has spurred renewed interest among many HIV-positive women in their decisions about whether to have children. It is important for perinatal nurses to understand the maternal and fetal implications of HIV in pregnancy, including parameters for treatment and the drug regimens typically used during the antepartum, intrapartum, and postpartum periods.

Efavirenz-based antiretroviral therapy versus nevirapine-including regimens for prevention of mother-to-child transmission of HIV option B plus in resource-limited settings: is there anything missing?

In 2013, an estimated 1.5 million HIV-positive pregnant women gave birth, with 240,000 children worldwide acquiring HIV. More than 90% of new pediatric infections occurred in Sub-Saharan Africa. The latest WHO guidelines recommended efavirenz (EFV)-based antiretroviral therapy as the first-line regimen for prevention of mother-to-child transmission of HIV (PMTCT). On the other hand, some data suggest that nevirapine (NVP), a well-known antiretroviral, could still play a relevant role in PMTCT, especially in resource-limited settings (RLSs) where the fertility rate is dramatically high compared to developed countries. Given the lack of an unanimous consensus and definitive opinions, this paper goes through the reasons for WHO decisions and aims at refreshing the debate about NVP and EFV pros and cons for PMTCT in RLSs.

Eliminating mother-to-child transmission of the human immunodeficiency virus in sub-Saharan Africa: The journey so far and what remains to be done

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.

Research gaps in neonatal HIV-related care

The South African prevention of mother to child transmission programme has made excellent progress in reducing vertical HIV transmission, and paediatric antiretroviral therapy programmes have demonstrated good outcomes with increasing treatment initiation in younger 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 follow-up, and failure to initiate HIV-infected infants on antiretroviral therapy (ART) before disease progression 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 addressing these gaps. The present article highlights a number of areas where evidence is lacking to inform guidelines and programme development for optimal neonatal HIV-related care.
