Over a third of childbearing women with HIV would like to breastfeed: A UK survey of women living with HIV

Infant Feeding for Persons Living With and at Risk for HIV in the United States: Clinical Report

Pediatricians and pediatric health care professionals caring for infants born to people living with and at risk for HIV infection are likely to be involved in providing guidance on recommended infant feeding practices. Care team members need to be aware of the HIV transmission risk from breastfeeding and the recommendations for feeding infants with perinatal HIV exposure in the United States. The risk of HIV transmission via breastfeeding from a parent with HIV who is receiving antiretroviral treatment (ART) and is virally suppressed is estimated to be less than 1%. The American Academy of Pediatrics recommends that for people with HIV in the United States, avoidance of breastfeeding is the only infant feeding option with 0% risk of HIV transmission. However, people with HIV may express a desire to breastfeed, and pediatricians should be prepared to offer a family-centered, nonjudgmental, harm reduction approach to support people with HIV on ART with sustained viral suppression below 50 copies per mL who desire to breastfeed. Pediatric health care professionals who counsel people with HIV who are not on ART or who are on ART but without viral suppression should recommend against breastfeeding. Pediatric health care professionals should recommend HIV testing for all pregnant persons and HIV preexposure prophylaxis to pregnant or breastfeeding persons who test negative for HIV but are at high risk of HIV acquisition.

Guidelines and practice of breastfeeding in women living with HIV-Results from the European INSURE survey

INTRODUCTION

Antiretroviral therapy (ART) is integral to HIV prevention, including averting vertical transmission. The World Health Organization (WHO) recommends ART and breastfeeding for all women living with HIV for at least 12 months post-partum [1, 2]. Much of the data on HIV transmission through breastfeeding comes from low-resource settings, with a paucity of data on breastfeeding-related HIV transmission in women living with HIV in other settings. Women Against Viruses in Europe (WAVE), part of the European AIDS Clinical Society (EACS), aims to improve the standard of care for women living with HIV and sought to gain an understanding of breastfeeding guidelines and practice in women living with HIV across Europe.

METHODS

A steering group convened by WAVE developed a survey to collate information on breastfeeding trends, practice, and guideline recommendations for women living with HIV in Europe and to establish interest in becoming involved in a collaborative breastfeeding network. The survey was disseminated to 31 countries in March 2022.

RESULTS

In total, 25 eligible responses were received: 23/25 (92%) countries have HIV and pregnancy guidelines; 23/23 (100%) guidelines refer specifically to breastfeeding; 12/23 (52%) recommend against breastfeeding; 11/23 (48%) offer an option if certain criteria are met; 12/25 (48%) reported that the number of women living with HIV who breastfeed is increasing; 24/25 (96%) respondents were interested in joining a network on breastfeeding in women living with HIV.

CONCLUSIONS

Recommendations vary, and nearly half of the guidelines recommend against breastfeeding. Many countries report an increase in breastfeeding. WAVE will establish a collaborative network to bridge data gaps, conduct research, and improve support for women living with HIV who choose to breastfeed.

Infant feeding: emerging concepts to prevent HIV transmission

PURPOSE OF REVIEW

HIV screening in pregnancy, universal suppressive antiretroviral therapy (ART) and breastfeeding avoidance can almost completely prevent vertical transmission of HIV. Breastfeeding is associated with an additional risk of transmission, although this risk is extremely low with suppressive maternal ART. This minimal risk must be balanced with the benefits of breastfeeding for women living with HIV (WLHIV) and their infants. Guidance in high-income countries has evolved, moving towards supported breast feeding for women on suppressive ART.

RECENT FINDINGS

Breastmilk transmission accounts for an increasing proportion of new infant infections globally. The majority of transmission data comes from studies including women not on suppressive ART. Breastmilk transmissions in the context of undetectable viral load have rarely occurred, although risk factors remain unclear. Outcome data on supported breastfeeding are accumulating, providing evidence for guidelines and informing infant feeding decisions. Long-acting ART for maternal preexposure prophylaxis or treatment, and infant postnatal prophylaxis are promising future options.

SUMMARY

Breastfeeding on suppressive ART has a very low risk of vertical transmission and can have multiple benefits for WLHIV and their infants. However, caution is advised with relaxation of breastfeeding guidance so as not to jeopardise the global goal of elimination of vertical transmission by 2030.

"We decided together": a qualitative study about women with HIV navigating infant-feeding decisions with the father of their children

BACKGROUND

The World Health Organization (WHO) recommends that women with HIV breastfeed for a minimum of one year. In contrast, United Kingdom (UK) guidelines encourage formula feeding, but breastfeeding can be supported under certain circumstances. Infant-feeding decisions often involve personal and social networks. Currently, little research addresses how individuals with HIV in high-income countries navigate infant-feeding decisions with the father of their children.

METHODS

Semi-structured remote interviews were conducted with UK-based individuals with a confirmed HIV positive diagnosis who were pregnant or one-year postpartum, and two partners. Using purposive sampling, pregnant and postpartum participants were recruited through HIV NHS clinics and community-based organisations, and where possible, fathers were recruited via them. Data were analysed using thematic analysis and organised using NVivo 12.

RESULTS

Of the 36 women interviewed, 28 were postpartum. The majority were of Black African descent (n = 22) and born outside the UK. The key factors in women navigating HIV and infant-feeding discussions with respect to their baby's father were the latter's: (1) awareness of woman's HIV status; (2) relationship with the woman; (3) confidence in infant-feeding decision; (4) support and opinion about woman's infant-feeding intentions. Most women made a joint decision with biological fathers when in a long-term (> one year) relationship with them. Single women tended not to discuss their infant-feeding decision with the father of their child, often for safety reasons.

CONCLUSION

Women in ongoing relationships with the father of their child valued their support and opinions regarding infant-feeding. In contrast, single women chose not to involve the father for reasons of privacy and safety. Clinical teams and community-based organisations should support mothers in discussing infant-feeding decisions regardless of relationship status. When appropriate, they should also support discussions with their partners, but remain sensitive to circumstances where this may put women at risk.

Perception and Emotional Experiences of Infant Feeding Among Women Living With HIV in a High-Income Setting: A Longitudinal Mixed Methods Study

BACKGROUND

The recommendation of breastfeeding avoidance for women living with HIV in high-income settings may be influenced by cultural beliefs and come at an emotional cost. This multicenter, longitudinal, convergent mixed methods study aimed to compare differences in attitudes, concerns, and experiences surrounding breastfeeding in women living with HIV of Nordic and non-Nordic origin.

SETTING

High-income setting.

METHODS

Pregnant women living with HIV in the Nordic countries Denmark, Finland, and Sweden were recruited in 2019-2020. Quantitative data on attitudes surrounding infant feeding were assessed using the Positive Attitudes Concerning Infant Feeding questionnaire completed in the third trimester (T1), and 3 (T2) and 6 (T3) months postpartum. Women who completed the survey were also invited to participate in semistructured interviews at T1 and T3. The findings from the quantitative survey and qualitative interviews were brought together through merging to assess for concordance, complementarity, expansion, or discordance between the data sets and to draw metainferences.

RESULTS

In total, 44 women completed the survey, of whom 31 also participated in qualitative interviews. The merged analyses identified three overarching domains representing commonalities across the quantitative and qualitative data: emotional impact, justifying not breastfeeding, and coping strategies. Not being able to breastfeed was emotionally challenging. Cultural expectations influenced the women's experiences and the strategies they used to justify their infant feeding choice.

CONCLUSIONS

For women living with HIV in Nordic countries not breastfeeding was a complex, multilayered process substantially influenced by social and cultural expectations.

Setting the research agenda: involving parents in research on children who are HIV-free

INTRODUCTION

There is growing interest in health, developmental and survival outcomes of children who are born HIV-free to women living with HIV (children born HIV-free). To date, the research agenda has been largely determined by researchers, funders and policy makers, with limited involvement of parents, who are key stakeholders. Researchers at UCL Great Ormond Street Institute of Child Health in partnership with community-based organisation 4M Network of Mentor Mothers conducted two workshops with parents in March 2022 to establish research priorities for children born HIV-free, and key considerations for methodological approaches both to research and engagement with the affected communities.

DISCUSSION

When exploring research on children born HIV-free, we consider the following: what aspects of current research are aligned with women and parents' priorities, what is missing and what approaches would be preferred. A holistic approach to research on children born HIV-free should be prioritised, focussing on a breadth of outcomes and how they intersect. Secondary use of existing data sources should be maximised to facilitate this, with a view of monitoring the long-term effects of fetal antiretroviral drug exposure alongside other key health and developmental outcomes. Involving and engaging with parents, and children where possible, must be at the heart of research design to maximise relevance and impact of findings for the affected communities. Potential barriers to engaging with individuals who were children born HIV-free include parental disclosure and individuals not identifying as a child born HIV-free to a mother living with HIV. Stigma-free language must be incorporated into the vocabulary of researchers and other stakeholders, avoiding reference to exposure; we propose the term "children born HIV-free."

CONCLUSIONS

Mothers and parents living with HIV should be involved in research about their children born HIV-free and are key in identifying research priorities so that findings may translate into an impact on their children's health and wellbeing. Meaningful involvement of women living with HIV through trusted community partners is an effective mechanism by which to elicit views on research about their children.

Infant feeding for people living with HIV in high resource settings: a multi-disciplinary approach with best practices to maximise risk reduction

Shared decision making for infant feeding in the context of HIV in high-resourced settings is necessary to acknowledge patient autonomy, meet increasing patient requests and address the changing reality of perinatal HIV care. In low-to middle-income countries (LMIC), where the majority of individuals living with HIV reside, persons with HIV are recommended to breastfeed their infants. In the setting of maternal anti-retroviral therapy (ART) use throughout pregnancy, viral suppression and appropriate neonatal post-exposure prophylaxis (PEP) use, updated information indicates that the risk of HIV transmission through breastmilk may be between 0.3 and 1%. While not endorsing or recommending breastfeeding, the United States' DHHS perinatal guidelines are similarly pivoting, stating that individuals should "receive patient-centred, evidence-based counselling on infant feeding options." Similar statements appear in the British, Canadian, Swiss, European, and Australasian perinatal guidelines. We assembled a multi-disciplinary group at our institution to develop a structured shared decision-making process and protocol for successful implementation of breastfeeding. We recommend early and frequent counselling about infant feeding options, which should include well known benefits of breastfeeding even in the context of HIV and the individual's medical and psychosocial circumstances, with respect and support for patient's autonomy in choosing their infant feeding option.

Exploring the Breastfeeding Desires and Decision-Making of Women Living with HIV in the Netherlands: Implications for Perinatal HIV Management in Developed Countries

Introduction: Guidelines in high-income countries recommend women living with human immunodeficiency virus (HIV) to formula feed their newborns, because the possibility of mother-to-child-transmission of HIV during breastfeeding cannot be ruled out. It is an ongoing debate if the possible transmission risk outweighs the medical, cultural, psychological, and social importance of breastfeeding in women stable on current first-line suppressive antiretroviral regimens. The study aim was to explore breastfeeding desires and decision-making of immigrant and nonimmigrant women living with HIV in the Netherlands. Method: A questionnaire was administered orally or online to 82 women living with HIV in the Netherlands. The breastfeeding desires of the participants were collected as categorical data, and breastfeeding decision-making and willingness to adhere to additional monitoring were collected on a 5-point Likert scale. Categorical data were presented as proportions, and Likert scale data were presented in Likert scale bar plots. Results: Seventy-one percent of the participants expressed a desire to breastfeed in the future. The most important factors influencing decision-making to breastfeed were the chance of transmission of HIV to the infant and the advice by the doctor or nurse practitioner. Of the participants, 42% expressed their interest in breastfeeding with a <1/100 transmission risk. More than half of the participants expressed their interest to breastfeed with additional monitoring. Conclusions: A substantial proportion of the women living with HIV in the Netherlands has a desire to breastfeed, of which the majority are willing to adhere to additional monitoring to do so.

Successful implementation of new Swiss recommendations on breastfeeding of infants born to women living with HIV

INTRODUCTION

Swiss national recommendations advise, since end of 2018, supporting women with HIV who wish to breastfeed. Our objective is to describe the motivational factors and the outcome of these women and of their infants.

METHODS

mothers included in MoCHiV with a delivery between January 2019 and February 2021 who fulfilled the criteria of the "optimal scenario" (adherence to cART, regular clinical care, and suppressed HIV plasma viral load (pVL) of <50 RNA copies/ml) and who decided to breastfeed after a shared decision-making process, were approached to participate in this nested study and asked to fill-in a questionnaire exploring the main motivating factors for breastfeeding.

RESULTS

Between January 9, 2019 and February 7, 2021, 41 women gave birth, and 25 decided to breastfeed of which 20 accepted to participate in the nested study. The three main motivational factors of these women were bonding, neonatal and maternal health benefits. They breastfed for a median duration of 6.3 months (range 0.7-25.7, IQR 2.5-11.1). None of the breastfed neonates received HIV post-exposure prophylaxis. There was no HIV transmission: 24 infants tested negative for HIV at least 3 months after weaning; one mother was still breastfeeding when we analyzed the data.

CONCLUSIONS

As a result of a shared decision-making process, a high proportion of mothers expressed a desire to breastfeed. No breastfed infant acquired HIV. The surveillance of breastfeeding mother-infant pairs in high resource settings should be continued to help update guidelines and recommendations.

Tilting the Scale: Current Provider Perspectives and Practices on Breastfeeding with HIV in the United States

The risk of vertical transmission from breastfeeding with HIV (BFHIV) has been found to be very low in optimal scenarios with sustained maternal viral suppression during pregnancy and postpartum. Medical providers must account for the risk of this serious adverse event alongside parental autonomy, breastfeeding benefits, and patient values. To assess provider practices, comfort, and challenges with BFHIV, an online mixed-method survey was sent to breastfeeding and HIV provider listservs from June to July 2021. The target population was US medical professionals from diverse practice settings with experience in clinical issues associated with BFHIV, including physicians, advanced practice providers, nurses, and lactation consultants. Data analysis utilized nonparametric hypothesis testing, ordinal regression, and reflexive thematic analysis. Most providers reported counseling pregnant people with HIV on infant feeding choices, but fewer specifically endorsed counseling about breastfeeding. Of 84 unique institutions identified by 100 included respondents, 10% had an institutional protocol supporting BFHIV. Institutional protocols were associated with higher degrees of provider comfort with BFHIV in optimal scenario clinical vignettes. Providers perceived that White patients faced fewer BFHIV barriers than patients with other racial identities. Discomfort balancing the goals to protect infants from infection risk and support the parent's role in infant feeding decisions was a key theme in free text responses; this manifested in a spectrum of management styles ranging from patient's informed choice to paternalism. This study highlights the tension providers navigate regarding BFHIV discussions, calling for patient care guidelines and protocols grounded in risk reduction and respect of patient autonomy.

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 &lt;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 &gt;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.
