Effect of peer-mother interactive programme on prevention of mother-to-child HIV transmission outcomes among pregnant women on anti-retroviral treatment in routine healthcare in Dar es Salaam, Tanzania

The Childbirth Experience of Pregnant Women Living with HIV Virus

Objective: The aim of this study was to examine the childbirth satisfaction of pregnant women living with HIV virus (PWLWHIV) and its association with selected variables in order to improve it. Methods: A total of 82 PWLWHIV were interviewed at an Institute in Rio de Janeiro. Maternal satisfaction was measured using the Brazilian version of the Mackey Childbirth Satisfaction Rating Scale, which was translated to Brazilian Portuguese by Lopes, who validated the translated version. The Mackey scale is divided into six subscales: self-evaluation, partner, baby, midwives, doctors, and overall satisfaction. Results: The PWLWHIV experienced a good total childbirth satisfaction (score 133 out of 165) and good overall childbirth satisfaction (score 12 out of 15). The PWLWHIV also experienced a good self-satisfaction (score 37.3 out of 45), good satisfaction with partner (score 8.96 out of 10), good satisfaction with midwives (score 35.1 out of 45), and good satisfaction with doctors (score 31.2 out of 45). The PWLWHIV also experienced satisfaction with their babies (score 8.48 out of 10). Significant associations were found through univariable and multiple regression analysis, regarding complications with baby at birth (p < 0.001) on the total, overall, self, partner, midwife, and doctor subscales. Conclusions: PWLWHIV had a positive experience at childbirth in the public maternities units of Rio de Janeiro. Our findings indicate that complications regarding baby health at birth were the main factor associated with a negative experience.

"I desire to have an HIV-free baby": pregnant and breastfeeding mothers' perceptions of Viral load testing and suppression in HIV care in southwestern Uganda

Introduction

Viral suppression is a critical component for preventing mother-to-child transmission of HIV(MTCT). Mothers' perceptions of viral load suppression is crucial in the attainment of successful outcomes in preventing mother to child transmission of HIV. We therefore aimed to explore the experiences and perceptions of women on viral suppression.

Methods

This was a qualitative sub-study embedded in a cluster-randomized trial (NCT04122144) designed to improve viral load outcomes among pregnant and breastfeeding mothers living with HIV in four level III/IV health facilities in South-western Uganda. Thirty-two in-depth interviews were conducted with pregnant and breastfeeding women with HIV from 1st March 2020 to 30th September 2020 to explore their understanding and interpretation of viral suppression. Interviews were audio-recorded, transcribed, and coded in Dedoose software for analysis.

Results

A total of 32 Women living with HIV were enrolled in this qualitative study. WLHIV explained viral suppression in the context of attaining good health and having HIV-free babies. Adherence to ART was presented as a key avenue to viral suppression. The level of engagement with providers was presented as a key attribute of attaining viral suppression. The participants narrated their experiences with viral load testing within the routine services. However, they revealed experiencing some proximate barriers to suppression including anticipated stigma, challenges with non-disclosure of HIV status, pregnancy distress, and distance to the health facility.

Conclusion

The understanding and interpretation of viral suppression among pregnant and breastfeeding mothers living with HIV provides a basis for adopting behaviors leading to prevention of vertical transmission of HIV. Health care workers can support women by providing clear and culturally appropriate education about viral suppression, adherence strategies and creating a supportive and non-judgmental environment.

Preventing perinatal HIV acquisition; current gaps and future perspectives

PURPOSE OF REVIEW

Although current treatment could eradicate vertical transmission, in 2022, 130 000 infants acquired HIV globally. HIV suppression with antiretroviral therapy (ART) transforms survival for people living with HIV (PLWH), and prevents transmission, including vertical. International guidelines recommend lifelong ART for PLWH, consequently perinatal HIV acquisition reflects implementation gaps in the HIV care cascade. We summarize these gaps, exploring potential novel approaches and therapeutic innovations towards eliminating vertical HIV transmission.

RECENT FINDINGS

Multifactorial challenges continue to underpin gaps in the HIV care cascade, including accessibility, availability and sustainability of HIV testing, prevention and treatment, alongside stigma, gender-based violence and poverty. Long-acting ART may be important in preventing perinatal HIV acquisition, with early data demonstrating tolerability and efficacy of injectable ART throughout pregnancy, both as HIV treatment and prevention. Carefully selected long-acting broadly neutralizing antibodies (bNAbs) matching circulating, exposing viral envelope sequences have demonstrated safety, clinical trials are ongoing to demonstrate efficacy.

SUMMARY

Emerging clinical studies should prioritize pregnant/lactating people and infants to ensure such therapies are well tolerated and efficacious. Alongside therapeutic innovation, programmatic strategies must address social and economic challenges, ensuring sustainable HIV treatment/prevention programmes and facilitating global elimination of blood-borne viruses.

Influence of peer discussions on trust in recommendations for prevention of mother-to-child transmission (PMTCT) of HIV

BACKGROUND

Mothers attending prevention of mother-to-child transmission (PMTCT) of HIV clinics seem to lack knowledge on many aspects of PMTCT, among which is breastfeeding. Breastfeeding recommendations in PMTCT have changed several times over the years leaving some confused and doubtful of what is currently recommended. One method shown to help improve their knowledge and acceptance of PMTCT recommendations is the use of peer educators. We sought to determine if mothers engage in discussions with other mothers during clinics and how these engagements influence trust in PMTCT recommendations.

METHODS

We interviewed 524 mothers with children under two years enrolled in PMTCT clinics in Kilimanjaro, Tanzania. We selected 5 clinics with the highest numbers of PMTCT enrolment from each district in the region. In each clinic, over a one-month period, we recruited all mothers attending the PMTCT clinic. We collected information on their engagement in discussions regarding PMTCT during clinics and how they perceived the information from their peers in relation to that from healthcare providers.

RESULTS

Fifty-five percent of the mothers reported engaging in peer discussions. Of the 90 (17%) mothers who reported noticing a change in PMTCT recommendations, 33 (36.7%) reported trusting previous recommendations more. A greater proportion (52.9%) of mothers who engaged in peer discussions reported trusting the information from peers more than that from healthcare workers.

CONCLUSIONS

Peers have a great influence on mothers, which is concerning when their knowledge shared is outdated. Harnessing their influence and training them on current recommendations might be key to improving adherence to PMTCT recommendations.

Perspectives and thoughts of pregnant women and new mothers living with HIV receiving peer support: A mixed studies systematic review

AIM

The aim of this study was to systematically consolidate evidence on perspectives and thoughts of women living with HIV regarding the peer support they have encountered during pregnancy and after childbirth.

DESIGN

Mixed studies systematic review.

DATA SOURCES

PubMed, EMBASE, Cochrane, PsycINFO, CINAHL, Scopus and ProQuest were sourced from 1981 to January 2022.

METHODS

A convergent qualitative synthesis approach was used to analyse the data. Quality appraisal was performed using the Mixed Methods Appraisal Tool.

RESULTS

A total of 12 studies were included, involving 1596 pregnant women and 1856 new mothers living with HIV. An overarching theme, 'From One Mother to Another: The Supportive Journey of Pregnant Women and New Mothers Living with HIV', and two themes were identified: (1) Emotional support buddies and extended networks and (2) Link bridge to healthcare support and self-empowerment.

CONCLUSION

Peer support played an indispensable role in the lives of women living with HIV and served as a complementary support system to professional and family support.

IMPACT

What problem did the study address? Pregnant women and new mothers living with HIV face preconceived stigma and discrimination. What were the main findings? Peer support was perceived to be beneficial in enhancing emotional support among women living with HIV and was well-accepted by them. Where and on whom will the research have an impact? Healthcare providers and community social workers could develop or enhance peer support educational programmes tailored to pregnant women and new mothers living with HIV. Policymakers and administrators can leverage public awareness, advocacy and political will to formulate and implement policies and campaigns aimed at fostering awareness and receptivity towards peer support interventions.

Enhanced peer-group strategies to support the prevention of mother-to-child HIV transmission leads to increased retention in care in Uganda: A randomized controlled trial

INTRODUCTION

Despite the scale-up of Option B+, long-term retention of women in HIV care during pregnancy and the postpartum period remains an important challenge. We compared adherence to clinic appointments and antiretroviral therapy (ART) at 6 weeks, 6, and and 24 months postpartum among pregnant women living with HIV and initiating Option B+. Women were randomized to a peer group support, community-based drug distribution and income-generating intervention called "Friends for Life Circles" (FLCs) versus the standard of care (SOC). Our secondary outcome was infant HIV status and HIV-free survival at 6 weeks and 18 months postpartum.

METHODS

Between 16 May 2016 and 12 September 2017, 540 ART-naïve pregnant women living with HIV at urban and rural health facilities in Uganda were enrolled in the study at any gestational age. Participants were randomized 1:1 to the unblinded FLC intervention or SOC at enrolment and assessed for adherence to the prevention of mother-to-child HIV transmission (PMTCT) clinic appointments at 6 weeks, 12, and 24 months postpartum, self-reported adherence to ART at 6 weeks, 6 and 24 months postpartum and supported by plasma HIV-1 RNA viral load (VL) measured at the same time points, retention in care through the end of study, and HIV status and HIV-free survival of infants at 18 months postpartum. The FLC groups were formed during pregnancy within 4 months of enrollment and held monthly meetings in their communites, and were followed up until the last group participant reached 24 months post delivery. We used Log-rank and Chi-Square p-values to test the equality of Kaplan-Meier survival probabilities and hazard rates (HR) for failure to retain in care for any reason by study arm.

RESULTS

There was no significant difference in adherence to PMTCT clinic visits or to ART or in median viral loads between FLC and SOC arms at any follow-up time points. Retention in care through the end of study was high in both arms but significantly higher among participants randomized to FLC (86.7%) compared to SOC (79.3%), p = 0.022. The adjusted HR of visit dropout was 2.4 times greater among participants randomized to SOC compared to FLC (aHR = 2.363, 95% CI: 1.199-4.656, p = 0.013). Median VL remained < 400 copies/ml in both arms at 6 weeks, 6, and 24 months postpartum. Eight of the 431 infants tested at 18 months were HIV positive (1.9%), however, this was not statistically different among mothers enrolled in the FLC arm compared to those in the SOC arm. At 18 months, HIV-free survival of children born to mothers in the FLC arm was significantly higher than that of children born to mothers in the SOC arm.

CONCLUSIONS

Our findings suggest that programmatic interventions that provide group support, community-based ART distribution, and income-generation activities may contribute to retention in PMTCT care, HIV-free survival of children born to women living with HIV, and ultimately, to the elimination of mother-to-child HIV transmission (EMTCT).

Long-term retention on antiretroviral treatment after enrolment in prevention of vertical HIV transmission services: a prospective cohort study in Dar es Salaam, Tanzania

INTRODUCTION

To prevent vertical HIV transmission and ensure healthy mothers and children, pregnant women with HIV must remain on antiretroviral treatment (ART) for life. However, motivation to remain on ART may decline beyond the standard 2-year breastfeeding/postpartum period. We assessed attrition and retention in ART care among women with HIV up to 6 years since enrolment in vertical transmission prevention services in Dar es Salaam, Tanzania.

METHODS

A prospective cohort of 22,631 pregnant women with HIV were enrolled in vertical transmission prevention services between January 2015 and December 2017 in routine healthcare settings and followed-up to July 2021. Kaplan-Meier was used to estimate time to ART attrition (died, stopped ART or was lost to follow-up [no show ≥90 days since scheduled appointment]) and the proportion retained in care. Cox proportional hazard models were used to estimate adjusted hazard ratios (aHR) of ART attrition in relation to predictors.

RESULTS

Participants were followed-up to 6 years for a median of 3 years (IQR: 0.1-4). The overall ART attrition rate was 13.8 per 100 person-years (95% CI: 13.5-14.1), highest in the first year of enrolment at 27.1 (26.3-27.9), thereafter declined to 9.5 (8.9-10.1) in year 3 and 2.7 (2.1-3.5) in year 6. The proportion of women retained in care were 78%, 69%, 63%, 60%, 57% and 56% at 1, 2, 3, 4, 5 and 6 years, respectively. ART attrition was higher in young women aged <20 years (aHR 1.63, 95% CI: 1.38-1.92) as compared to 30-39 year-olds and women enrolled late in the third versus first trimester (aHR 1.29, 95% CI: 1.16-1.44). In contrast, attrition was lower in older women ≥40 years, women who initiated ART before versus during the index pregnancy and women attending higher-level health facilities.

CONCLUSIONS

ART attrition among women with HIV remains highest in the first year of enrolment in vertical transmission prevention services and declines markedly following a transition to chronic HIV care. Targeted interventions to improve ART continuity among women with HIV during and beyond prevention of vertical transmission are vital to ending paediatric HIV and keeping women and children alive and healthy.

Enhanced Peer-Group strategies to support prevention of Mother-to-Child HIV transmission leads to increased retention in care in Uganda: A Randomized controlled trial

Introduction

Despite scale up of Option B+, long-term retention of women in HIV care during pregnancy and the postpartum period remains an important challenge. We compared adherence to clinic appointments and antiretroviral therapy (ART) at different follow-up time points between enrolment and 24 months postpartum among pregnant women living with HIV and initiating Option B+ randomized to a peer group support, community-based drug distribution and income-generating intervention called "Friends for Life Circles" (FLCs) versus the standard of care (SOC).

Methods

Between 16 May 2016 and 12 September 2017, 540 ART-naïve pregnant women living with HIV at urban and rural health facilities in Uganda were enrolled in the study. Participants were randomized 1:1 to the FLC intervention or SOC and assessed for adherence to prevention of mother to child HIV transmission (PMTCT) clinic appointments at 6 weeks, 12 and 24 months postpartum, self-reported adherence to ART at 6 weeks, 6 and 24 months postpartum validated by plasma HIV-1 RNA viral load (VL) measured at the same time points, and HIV status and HIV-free survival of infants at 18 months postpartum. We used Log-rank and Chi-Square p-values to test the equality of Kaplan-Meier survival probabilities and hazard rates (HR) for failure to retain in care for any reason by study arm.

Results

There was no significant difference in adherence to PMTCT clinic visits or to ART or in median viral loads between FLC and SOC arms at any follow-up time points. Retention in care through the end of study was high in both arms but significantly higher among participants randomized to FLC (86.7%) compared to SOC (79.3%), p=0.022. The adjusted HR of visit dropout was 2.5 times greater among participants randomized to SOC compared to FLC (aHR=2.498, 95% CI: 1.417 - 4.406, p=0.002). Median VL remained < 400 copies/ml in both arms at 6 weeks, 6 and 24 months postpartum.

Conclusions

Our findings suggest that programmatic interventions that provide group support, community based ART distribution and income-generation activities may contribute to retention in PMTCT care, HIV-free survival of children born to women living with HIV, and to the elimination of mother to child HIV transmission (MTCT).
