The association between ethnicity and late presentation to antenatal care among pregnant women living with HIV in the UK and Ireland

Trends in management and outcomes of pregnant women living with HIV between 2008–2013 and 2014–2019: A retrospective cohort study

Background

Despite major advances in the care of pregnant women living with HIV (WLHIV), they remain at increased risk of adverse pregnancy outcomes. This study assesses recent developments in management and outcomes of pregnant WLHIV at a tertiary obstetric unit in the United Kingdom.

Methods

We conducted a retrospective cohort study of WLHIV delivering at the John Radcliffe Hospital, Oxford, during 2008–2019. Detailed data was collected for maternal, virological, obstetric, and perinatal characteristics. To determine changes over time, data from the periods 2008–13 and 2014–19 were compared.

Results

We identified 116 pregnancies in 94 WLHIV. Between 2008–2013 and 2014–2019, the rate of preconception HIV diagnosis increased from 73 to 90% (p = 0.021) and the proportion of WLHIV on combination ART (cART) at conception increased from 54 to 84% (p = 0.001). The median gestation at which cART was initiated antenatally decreased from 22+1 to 17+1 weeks (p = 0.003). In 2014-2019, 41% of WLHIV received non-nucleoside reverse transcriptase inhibitor-based cART, 37% protease inhibitor-based cART, and 22% of cART regimens contained an integrase inhibitor. The proportion of WLHIV with a viral load <50 copies/mL at delivery rose from 87 to 94% (p = 0.235). Sixty-six percent of WLHIV delivered by Cesarean section, with a significant decrease over time in the rate of both planned (62–39%, p = 0.016) and actual (49–31%, p = 0.044) elective Cesarean. Perinatal outcomes included one case of perinatal HIV transmission (0.86%), 11% preterm birth, 15% small-for-gestational-age, and 2% stillbirth. There was an association between a viral load >50 copies/mL at delivery and preterm delivery (p = 0.0004).

Conclusion

Virological, obstetric, and perinatal outcomes of WLHIV improved during the study period. Implementation of national guidance has led to an increase in preconception diagnosis and treatment, earlier initiation of antenatal treatment, a reduction in the number of women with a detectable viral load at delivery, and an increase in vaginal deliveries.

Reproductive decision-making of Black women living with HIV: A systematic review

BACKGROUND

Black women living with HIV account for a higher proportion of new HIV diagnoses than other groups. These women experience restricted access to reproductive services and inadequate support from healthcare providers because their position in society is based on their sexual health and social identity in the context of this stigmatizing chronic disease. By recognizing the analytical relevance of intersectionality, the reproductive decision-making of Black women can be explored as a social phenomenon of society with varied positionality.

OBJECTIVE

The purpose of this review was to synthesize the evidence about the reproductive decision-making of Black women living with HIV in high-income countries from the beginning of the HIV epidemic to the present.

METHODS

This systematic review was guided by the JBI evidence synthesis recommendations. Searches were completed in seven databases from 1985 to 2021, and the review protocol was registered with PROSPERO (CRD420180919).

RESULTS

Of 3503 records, 22 studies were chosen for synthesis, including 19 observational and three qualitative designs. Nearly, all studies originated from the United States; the earliest was reported in 1995. Few studies provided detailed sociodemographic data or subgroup analysis focused on race or ethnicity. Influencing factors for reproductive decision-making were organized into the following seven categories: ethnicity, race, and pregnancy; religion and spirituality; attitudes and beliefs about antiretroviral therapy; supportive people; motherhood and fulfillment; reproductive planning; and health and wellness.

CONCLUSION

No major differences were identified in the reproductive decision-making of Black women living with HIV. Even though Black women were the largest group of women living with HIV, no studies reported a subgroup analysis, and few studies detailed sociodemographic information specific to Black women. In the future, institutional review boards should require a subgroup analysis for Black women when they are included as participants in larger studies of women living with HIV.

Prevalence and outcomes of pregnancies in women with HIV over a 20-year period

OBJECTIVE

To evaluate time trends in pregnancies and pregnancy outcomes among women with HIV in Europe.

DESIGN

European multicentre prospective cohort study.

METHODS

EuroSIDA has collected annual cross-sectional audits of pregnancies between 1996 and 2015. Pregnancy data were extracted and described. Odds of pregnancy were modelled, adjusting for potential confounders using logistic regression with generalized estimating equations.

RESULTS

Of 5535 women aged 16 to <50 years, 4217 (76.2%) had pregnancy information available, and 912 (21.6%) reported 1315 pregnancies. The proportions with at least one pregnancy were 28.1% (321/1143) in East, 24.5% (146/596) in North, 19.8% (140/706) in West/Central, 19.3% (110/569) in Central East and 16.2% (195/1203) in South Europe. Overall 319 pregnancies (24.3%) occurred in 1996-2002, 576 (43.8%) in 2003-2009 and 420 (31.9%) in 2010-2015. After adjustment, the odds of pregnancy were lower in 1996-2002, in South, Central East and East compared to West/Central Europe, in older women, those with low CD4+ cell count or with prior AIDS, and higher in those with a previous pregnancy or who were hepatitis C virus positive.Outcomes were reported for 999 pregnancies in 1996-2014, with 690 live births (69.1%), seven stillbirths (0.7%), 103 spontaneous (10.3%) and 199 medical abortions (19.9%).

CONCLUSIONS

Around 20% of women in EuroSIDA reported a pregnancy, with most pregnancies after 2002, when more effective antiretroviral therapy became available. Substantial differences were seen between European regions. Further surveillance of pregnancies and outcomes among women living with HIV is warranted to ensure equal access to care.

Stillbirth in Women Living With HIV Delivering in the United Kingdom and Ireland: 2007-2015

BACKGROUND

Women living with HIV have a higher risk of adverse birth outcomes, but questions remain regarding their specific risk factors for stillbirth and the extent to which maternal HIV is associated with stillbirth.

METHODS

Using data on pregnant women with HIV reported within population-based surveillance in the United Kingdom/Ireland, we described stillbirth rates in 2007-2015 stratified by type of antiretroviral therapy (ART) and evaluated risk factors using Poisson regression. General population stillbirth rates by maternal world region of origin were derived from national annual birth statistics, and compared with rates in women with HIV, using standardized stillbirth ratios with the general population as the reference.

RESULTS

Between 2007 and 2015, there were 10,434 singleton deliveries in 8090 women with HIV; 75% of pregnancies were in women of African origin; and 49% were conceived on ART. The stillbirth rate was 8.5 (95% confidence interval: 6.9 to 10.5) per 1000 births. Risk factors for stillbirth included pre-eclampsia, diabetes, Asian maternal origin (versus United Kingdom/Ireland), CD4 count <350 cells/mm, older maternal age, and primiparity. Conceiving on ART did not increase the risk. The stillbirth rates (per 1000 births) by type of ART were 14.3, 11.7, 8.3, and 6.0, respectively for NVP + XTC/TDF-, LPV/r + 3TC/ZDV-, NVP + XTC/ABC-, and NVP + XTC/ZDV-exposed pregnancies (P value = 0.40). The standardized stillbirth ratio was 129 (95% confidence interval: 101 to 165) in women with HIV compared with the general population.

CONCLUSION

After adjusting for maternal origin, the stillbirth rate remained higher in women with HIV than the general population. We recommend further studies to understand and prevent this excess.

Late booking amongst African women in a London borough, England: implications for health promotion

The National Institute for Health and Clinical Excellence guidance is that a pregnant woman should see a midwife within the first 13 weeks into her pregnancy, in what is known as the 'booking appointment' or the 'full assessment' where she discusses with the midwife her care plan, medical and family histories and social circumstances. Significant numbers of black African women present after 13 weeks into the pregnancy. This study explores why black African women access the booking appointment after 13 weeks of pregnancy in a London borough. The study took a qualitative approach and used semi-structured interviews with 23 women who self-identified as black African migrants born in a sub-Saharan African country, and had experience of using ante-natal services in the borough. Participants discussed how their cultural understandings of pregnancy influenced timing of the booking appointment. The data was analysed using the thematic approach. Cultural, economic and political contexts within which they experienced pregnancy influenced the timing. Whilst acknowledging the benefits of early booking, this was said to be at odds with their cultural beliefs where pregnancy disclosure within 13 weeks was considered inappropriate. Lack of information about the booking appointment and unresolved immigration issues led to perceptions that they were being brought under the Immigration Department's radar through the booking appointment. Whilst most health promotion information regarding the booking appointment is designed in a top-down fashion, health planners should also recognize ethnic diversities so as to market the booking appointment using downstream approaches that take account of the cultural, political and economic contexts in which migrants/ethnic minority populations live.

Why do sub-Saharan Africans present late for HIV care in Switzerland?

OBJECTIVES

Late presentation (LP) to HIV care disproportionally affects individuals from sub-Saharan Africa (SSA). We explored the reasons for late presentation to care among this group of patients in the Swiss HIV Cohort Study.

METHODS

The prevalence of LP was compared between patients from Western Europe (WE) and those from SSA enrolled between 2009 and 2012. Patients were asked about HIV testing, including access to testing and reasons for deferring it, during face-to-face interviews.

RESULTS

The proportion of LP was 45.8% (435/950) among patients from WE, and 64.6% (126/195) among those from SSA (P < 0.001). Women from WE were slightly more likely to present late than men (52.6% versus 44.5%, respectively; P = 0.06), whereas there was no sex difference in patients from SSA (65.6% versus 63.2%, respectively; P = 0.73). Compared with late presenters from WE, those from SSA were more likely to be diagnosed during pregnancy (9.1% versus 0%, respectively; P < 0.001), but less likely to be tested by general practitioners (25.0% versus 44.6%, respectively; P = 0.001). Late presenters from SSA more frequently reported 'not knowing about anonymous testing possibilities' (46.4% versus 27.3%, respectively; P = 0.04) and 'fear about negative reaction in relatives' (39.3% versus 21.7%, respectively; P = 0.05) as reasons for late testing. Fear of being expelled from Switzerland was reported by 26.1% of late presenters from SSA.

CONCLUSIONS

The majority of patients from SSA were late presenters, independent of sex or education level. Difficulties in accessing testing facilities, lack of knowledge about HIV testing and fear-related issues are important drivers for LP in this population.

Migrant women living with HIV in Europe: are they facing inequalities in the prevention of mother-to-child-transmission of HIV?: The European Pregnancy and Paediatric HIV Cohort Collaboration (EPPICC) study group in EuroCoord

Background

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.

Methods

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.

Results

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.

Conclusions

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.

Promoting high standards of care for women living with HIV: position statement from the Women Against Viruses in Europe Working Group

OBJECTIVES

Gender-related factors can influence management decisions, treatment outcomes and the overall long-term wellbeing of people living with HIV (PLWH). The Women Against Viruses in Europe (WAVE) Working Group was established to promote the health and wellbeing of women living with HIV (WLWH). WAVE is part of the European AIDS Clinical Society (EACS) and organizes annual workshops to discuss different issues in the management of WLWH.

METHODS

In 2016, 34 WAVE members including community representatives, HIV clinicians and researchers met to discuss standards of care for WLWH and to review current guidelines. Participants focused on three different themes: (1) access to and engagement and retention in care; (2) monitoring of women on antiretroviral therapy and management of comorbidities; and (3) review of EACS treatment guidelines.

RESULTS

Five priority areas for optimizing the care of WLWH were identified: (1) psychosocial aspects of HIV diagnosis and care; (2) mental health and wellbeing; (3) pharmacokinetics, toxicity and tolerability of antiretroviral therapy; (4) coinfections and comorbidities; and (5) sexual and reproductive health. WAVE recommendations are provided for each of these areas, and gaps in knowledge and needs for changes in currently existing standards are discussed.

CONCLUSIONS

This position statement provides an overview of the key recommendations to optimize the care of WLWH that emerged during the 2016 WAVE workshop.

Presentation for care and antenatal management of HIV in the UK, 2009-2014

OBJECTIVES

Despite very low rates of vertical transmission of HIV in the UK overall, rates are higher among women starting antenatal antiretroviral therapy (ART) late. We investigated the timing of key elements of the care of HIV-positive pregnant women [antenatal care booking, HIV laboratory assessment (CD4 count and HIV viral load) and antenatal ART initiation], to assess whether clinical practice is changing in line with recommendations, and to investigate factors associated with delayed care.

METHODS

We used the UK's National Study of HIV in Pregnancy and Childhood for 2009-2014. Data were analysed by fitting logistic regression and Cox proportional hazards models.

RESULTS

A total of 5693 births were reported; 79.5% were in women diagnosed with HIV prior to that pregnancy. Median gestation at antenatal booking was 12.1 weeks [interquartile range (IQR) 10.0-15.6 weeks] and booking was significantly earlier during 2012-2014 vs. 2009-2011 (P < 0.001), although only in previously diagnosed women. Overall, 42.2% of pregnancies were booked late (≥ 13 gestational weeks). Among women not already on treatment, antenatal ART commenced at a median of 21.4 (IQR18.1-24.5) weeks and started significantly earlier in the most recent time period (P < 0.001). Compared with previously diagnosed women, those newly diagnosed during the current pregnancy booked later for antenatal care and started antenatal ART later (both P < 0.001). Multivariable analyses revealed demographic variations in access to or uptake of care, with groups including migrants and parous women initiating care later.

CONCLUSIONS

Although women are accessing antenatal and HIV care earlier in pregnancy, some continue to face barriers to timely initiation of antenatal care and ART.

Late Diagnosis Due to Missed Opportunities and Inadequate Screening Strategies in HIV Infected Mexican Women

Late diagnosis of HIV remains a public health issue in Mexico. Most national programs target high-risk groups, not including women. More data on factors associated with late diagnosis and access to care in women are needed. In 2012-2013, Mexican women recently diagnosed with HIV were interviewed. Socio-cultural background, household-dynamics and clinical data were collected. Of 301 women, 49 % had <200 CD4 cells/mm³, 8 % were illiterate, 31 % had only primary school. Physical/sexual violence was reported by 47/30 %; 75 % acquired HIV from their stable partners. Prenatal HIV screening was not offered in 61 %; 40 % attended consultation for HIV-related symptoms without being tested for HIV. Seeking medical care ≥3 times before diagnosis was associated with baseline CD4 <200 cells/mm³ (adjusted OR 3.74, 95 % CI 1.88-7.45, p < 0.001). There were missed opportunities during prenatal screening and when symptomatic women seeked medical care. Primary care needs to be improved and new strategies implemented for early diagnosis in women.

Factors associated with late antenatal care booking: population based observations from the 2007 Zambia demographic and health survey

INTRODUCTION

In spite of the extreme importance of an early antenatal care visit, more than 50% of Zambian pregnant women book for antenatal care late. We aimed to determine factors associated with late antenatal care booking in Zambia.

METHODS

Data stem from the 2007 Zambia Demographic and Health Survey where information on socio-demographic, social-economic, obstetrical characteristics and timing of the first antenatal visit were extracted on all women aged 15 to 49 years. A weighted survey analysis using STATA version 12 was applied. Firstly, we explored proportions of ANC booking at 0-3 months, 4-5 month and 6-9 months. Secondly, we investigated the association between predictor variables and late antenatal care booking using univariate and multivariate logistic regression.

RESULTS

Overall (n= 3979), the proportion of late ANC booking (booking between 4th to 9th month) was 81% disaggregated as 56% and 19% at 4 to 5 months and 6 to 9 months respectively. Women who wanted their last child later were more likely to book late than those with wanted pregnancies then (AOR: 1.35 95% CI 1.10-1.66). Women with higher education were 55% less likely to book for ANC late compared to women with no education (AOR: 0.45 95%CI: 0.27-0.74). Women aged 20-34 years were 30% more likely to book earlier than women younger than 20 years (AOR: 0.69 95% CI 0.50-0.97).

CONCLUSION

We found high proportion of late ANC booking associated with presence of unplanned or unwanted pregnancies in this population. The concentration of this problem in lower or no education groups may be an illustration of existing inequalities which might further explain limitations in health promotion messages meant to mitigate this challenge. There is thus urgent need to re-pack health promotion message to specifically target this and related poor groups.

Brief Report: Consequences of Presentation With Advanced HIV Disease in Pregnancy: Data From a National Study in Italy

Among 469 women with a diagnosis of HIV in pregnancy, 74 (15.8%) presented with less than 200 CD4 cells per cubic millimeter. The only variable significantly associated with this occurrence was African origin (odds ratio: 2.22, 95% confidence intervals: 1.32 to 3.75, P = 0.003). Four women with low CD4 (5.6%), compared with none with higher CD4 counts, had severe AIDS-defining conditions (P < 0.001) during pregnancy or soon after delivery, and one transmitted HIV to the newborn. Early preterm delivery (<32 weeks) was significantly more frequent with low CD4 (6.2% vs. 1.4%, P = 0.015). An earlier access to HIV testing, particularly among immigrants of African origin, can prevent severe HIV-related morbidity.

Adequacy of prenatal care among women living with human immunodeficiency virus: a population-based study

Background

Prenatal care reduces perinatal morbidity. However, there are no population-based studies examining the adequacy of prenatal care among women living with HIV. Accordingly, we compared the prevalence of adequate prenatal care among women living with and without HIV infection in Ontario, Canada.

Methods

Using administrative data in a universal single-payer setting, we determined the proportions of women initiating care in the first trimester and receiving adequate prenatal care according to the Revised-Graduated Prenatal Care Utilization Index . We also determined the proportion of women with HIV receiving adequate prenatal care by immigration status. We used generalized estimating equations with a logit link function to derive adjusted odds ratios (aORs) and 95 % confidence intervals (CI) for all analyses.

Results

Between April 1, 2002 and March 31, 2011, a total of 1,132,135 pregnancies were available for analysis, of which 634 (0.06 %) were among women living with HIV. Following multivariable adjustment, women living with HIV were less likely to receive adequate prenatal care (36.1 % versus 43.3 %; aOR 0.74, 95 % CI 0.62 to 0.88) or initiate prenatal care in the first trimester (50.8 % versus 70.0 %; aOR 0.51, 95 % CI 0.43 to 0.60) than women without HIV. Among women with HIV, recent (i.e. ≤ 5 years) immigrants from Africa and the Caribbean were less likely to receive adequate prenatal care (25.5 % versus 38.5 %; adjusted odds ratio 0.51; 95 % CI, 0.32 to 0.81) than Canadian-born women.

Conclusion

Despite universal health care, disparities exist in the receipt of adequate prenatal care between women living with and without HIV. Interventions are required to ensure that women with HIV receive timely and adequate prenatal care.

The new face of the pediatric HIV epidemic in Western countries: demographic characteristics, morbidity and mortality of the pediatric HIV-infected population

The natural history of the pediatric HIV epidemic has changed since the introduction of strategies for the prevention of mother-to-child transmission and the implementation of highly active antiretroviral therapy. The demographic characteristics of the pediatric HIV-infected population and the incidence and pattern of HIV-related morbidity, as well as mortality rates, have been remarkably modified. This report gives an overview on the main changes that occurred in Western countries.

Rate, predictors, and consequences of late antenatal booking in a national cohort study of pregnant women with HIV in Italy

OBJECTIVE

To evaluate the prevalence and consequences of late antenatal booking (13 or more weeks gestation) in a national observational study of pregnant women with HIV.

METHODS

The clinical and demographic characteristics associated with late booking were evaluated in univariate analyses using the Mann-Whitney U test for quantitative data and the chi-square test for categorical data. The associations that were found were re-evaluated in multivariable logistic regression models. Main outcomes were preterm delivery, low birthweight, nonelective cesarean section, birth defects, undetectable (<50 copies/mL) HIV plasma viral load at third trimester, delivery complications, and gender-adjusted and gestational age-adjusted Z scores for birthweight.

RESULTS

Rate of late booking among 1,643 pregnancies was 32.9%. This condition was associated with younger age, African provenance, diagnosis of HIV during pregnancy, and less antiretroviral exposure. Undetectable HIV RNA at third trimester and preterm delivery were significantly more prevalent with earlier booking (67.1% vs 46.3%, P < .001, and 23.2% vs 17.6, P = .010, respectively), whereas complications of delivery were more common with late booking (8.2% vs 5.0%, P = .013). Multivariable analyses confirmed an independent role of late booking in predicting detectable HIV RNA at third trimester (adjusted odds ratio [AOR], 1.7; 95% CI, 1.3-2.3; P < .001) and delivery complications (AOR, 1.8; 95% CI, 1.2-2.8; P = .005).

CONCLUSIONS

Late antenatal booking was associated with detectable HIV RNA in late pregnancy and with complications of delivery. Measures should be taken to ensure an earlier entry into antenatal care, particularly for African women, and to facilitate access to counselling and antenatal services. These measures can significantly improve pregnancy management and reduce morbidity and complications in pregnant women with HIV.

What's pregnancy got to do with it? Late presentation to HIV/AIDS services in Northeastern Brazil

Despite the known benefits of early treatment initiation for individual morbidity and mortality, as well as for reducing the risk of transmission, late presentation (LP) to HIV/AIDS services remains a major concern in many countries. There is little information on LP from middle- and low-income countries and studies that do evaluate LP commonly disaggregate data by sex. It is rare, however, for researchers to further disaggregate the data by pregnancy status so it remains unclear if pregnancy status modifies the effects associated with sex. The study was conducted at the only State Reference Center for HIV/AIDS in Salvador, Brazil's third largest city. LP was defined as a patient accessing services with a CD4 < 350 cells/mm(3). Data were abstracted from the electronic medical records of 1421 patients presenting between 2007 and 2009. CD4 counts and viral load (VL) information was validated with data from the National CD4/VL Database. Descriptive and bivariate statistics were conducted to inform the multivariate analysis. Adjusted prevalence ratios (APR) were estimated using generalized linear models due to the high frequency of the outcome. Half of the sample (52.5%; n = 621) was classified as LP. Compared to the prevalence among pregnant women (21.1%), the prevalence of LP was more than twice as high among non-pregnant women (56.0%) and among men (55.4%). The multivariate analysis demonstrated no statistical difference between men and nonpregnant women (APR 1.04; 95%CI 0.92-1.19), but the APR of LP for nonpregnant women was 53% less than men (APR 0.47; 95%CI 0.33-0.68). These results highlight the importance of analyzing data disaggregated not only by sex but also by pregnancy status to accurately identify the risk factors associated with LP so that programs and policies can effectively and efficiently address LP in Brazil and beyond.

Elimination of perinatal HIV infection in the USA and other high-income countries: achievements and challenges

PURPOSE OF REVIEW

To describe progress and challenges to elimination of mother-to-child HIV transmission (EMCT) in high-income countries.

RECENT FINDINGS

Despite ongoing declines in the number of perinatally HIV-infected infants in most high-income countries, the number of HIV-infected women delivering may be increasing, accompanied by apparent changes in this population, including higher percentages with antiretroviral 'pretreatment' (with possible antiretroviral resistance), other coinfections, mental health diagnoses, and recent immigration. The impact of antiretroviral resistance on mother-to-child transmission is yet to be defined. A substantial minority of infant HIV acquisitions occurs in the context of maternal acute HIV infection during pregnancy. Some infant infections occur after pregnancy, for example, by premastication of food, or breastfeeding (perhaps by an uninfected woman who acquires HIV while breastfeeding).

SUMMARY

The issues of EMCT are largely those of providing proper care for HIV-infected women. Use of combination ART by increasing proportions of the infected population may function as a structural intervention important to achieving this goal. Providers and public health systems need to be alert for HIV-serodiscordant couples in which the woman is uninfected and for changes in the population of HIV-infected pregnant women. Accurate data about HIV-exposed pregnancies are vital to monitor progress toward EMCT.

Prenatal ultrasound screening for fetal anomalies and outcomes in high-risk pregnancies due to maternal HIV infection: a retrospective study

Objective. To assess the prevalence of prenatal screening and of adverse outcome in high-risk pregnancies due to maternal HIV infection. Study Design. The prevalence of prenatal screening in 330 pregnancies of HIV-positive women attending the department for prenatal screening and/or during labour between January 1, 2002 and December 31, 2012, was recorded. Screening results were compared with the postnatal outcome and maternal morbidity, and mother-to-child transmission (MTCT) was evaluated. Results. One hundred of 330 women (30.5%) had an early anomaly scan, 252 (74.5%) had a detailed scan at 20–22 weeks, 18 (5.5%) had a detailed scan prior to birth, and three (0.9%) had an amniocentesis. In seven cases (2.12%), a fetal anomaly was detected prenatally and confirmed postnatally, while in eight (2.42%) an anomaly was only detected postnatally, even though a prenatal scan was performed. There were no anomalies in the unscreened group. MTCT occurred in three cases (0.9%) and seven fetal and neonatal deaths (2.1%) were reported. Conclusion. The overall prevalence of prenatal ultrasound screening in our cohort is 74.5%, but often the opportunity for prenatal ultrasonography in the first trimester is missed. In general, the aim should be to offer prenatal ultrasonography in the first trimester in all pregnancies. This allows early reassurance or if fetal disease is suspected, further steps can be taken.

Achieving rapid reduction of HIV-1 viral load in HIV-positive pregnant women close to term – an obstetric/medical emergency: a review of three cases

Summary

Mother-to-child transmission (MTCT) of HIV infection is now uncommon in the UK and the management of HIV-positive pregnant women is usually relatively straightforward. However, HIV viral load suppression may be difficult to achieve peripartum for women who book very late in pregnancy and those with a poor adherence to antiretroviral therapy (ART). These pregnancies are at a higher risk of MTCT due to high viral load (VL). Therefore, the development of interventions to achieve a rapid reduction of HIV VL is essential. We describe three relevant cases that presented to our unit over a 12-month period and discuss the strategies employed to manage these challenging cases. All babies were born healthy and were HIV proviral DNA-negative at 12 weeks postpartum. No serious adverse events were reported for the mothers or their babies.

How does HIV affect the reproductive choices of women of childbearing age?

The majority of women living with HIV are of childbearing age and many of these women wish to have a family. As a result of advances in the treatment and management of HIV, more reproductive opportunities are now available to this group. However, women living with HIV may still require education and guidance in a range of reproductive situations, including avoiding pregnancy, seeking fertility treatment or having a child. HIV physicians should be aware of recent data and guidance on these situations--including areas where more data are required--and consider them when deciding on appropriate management for their patients.

Using mixed methods in health research

Mixed methods research is the use of quantitative and qualitative methods in a single study or series of studies. It is an emergent methodology which is increasingly used by health researchers, especially within health services research. There is a growing literature on the theory, design and critical appraisal of mixed methods research. However, there are few papers that summarize this methodological approach for health practitioners who wish to conduct or critically engage with mixed methods studies. The objective of this paper is to provide an accessible introduction to mixed methods for clinicians and researchers unfamiliar with this approach. We present a synthesis of key methodological literature on mixed methods research, with examples from our own work and that of others, to illustrate the practical applications of this approach within health research. We summarize definitions of mixed methods research, the value of this approach, key aspects of study design and analysis, and discuss the potential challenges of combining quantitative and qualitative methods and data. One of the key challenges within mixed methods research is the successful integration of quantitative and qualitative data during analysis and interpretation. However, the integration of different types of data can generate insights into a research question, resulting in enriched understanding of complex health research problems.
