Behavioral Interventions can Mitigate Adverse Pregnancy Outcomes Among Women Conceiving on ART and Those Initiated on ART During Pregnancy: Findings From the MOTIVATE Trial in Southwestern Kenya.

ABSTRACT:

Background

Antiretroviral therapy (ART) is essential for the elimination of mother-to-child transmission and improved health outcomes for women living with HIV (WLWH). However, adverse pregnancy outcomes (APOs) among pregnant women on ART are a growing concern.

Methods

We investigated the associations between timing of ART initiation and APOs among pregnant WLWH receiving behavioral interventions (community mentor mothers and text messaging) in the Mother-Infant Visit Adherence and Treatment Engagement (MOTIVATE) study in southwestern Kenya. Log binomial models were used for estimation of relative risks (RRs) (adjusted for the clustered nature of data) evaluating APOs with 3 exposure comparisons: (1) preconception ART initiation vs. postconception initiation; (2) among postconception ART initiating women, comparisons across gestational ages at cART initiation (first versus second and third trimester exposure), and (3) intervention allocation.

Results

Of the 1275 women included in this analysis, 388 (30%) had an APO: 306 preterm births, 38 low birth weight infants, 33 stillbirths, and 11 miscarriages. In multivariable analysis, viral load ≥1000 copies/mL, moderate and severe anemia at baseline increased risk of APOs. Among women initiating ART before and after conception, no difference was observed in the composite APO. Women who received community mentor mother visits alone (aRR 0.74: 95% CI: 0.71 to 0.76) or text messages alone (aRR 0.79: 95% CI: 0.70 to 0.89) had lower risks of experiencing any APOs.

Conclusions

Receiving supportive behavioral interventions may mitigate the risk of experiencing an APO among WLWH on ART. Further studies are needed to investigate the underlying mechanisms and optimize the benefits of these interventions.

Project description:BackgroundScaling up the antiretroviral (ART) program in Kenya has involved a strategy of using clinical guidelines coupled with decentralization of treatment sites. However decentralization pushes clinical responsibility downwards to health facilities run by lower cadre staff. Whether the organizational culture in health facilities affects the outcomes despite the use of clinical guidelines has not been explored. This study aimed to demonstrate the relationship between organizational culture and early mortality and those lost to follow up (LTFU) among patients enrolled for HIV care.Methods and materialsA stratified sample of 31 health facilities in Nairobi County offering ART services were surveyed. Data of patients enrolled on ART and LTFU for the 12 months ending 30th June 2013 were abstracted. Mortality and LTFU were determined and used to rank health facilities. In the facilities with the lowest and highest mortality and LTFU key informant interviews were conducted using a tool adapted from team climate assessment measurement questionnaire and competing value framework tool to assess organizational culture. The strength of association between early mortality, LTFU and organizational culture was tested.ResultsHalf (51.8%) of the 5,808 patients enrolled into care in 31 health facilities over the 12-month study period were started on ART. Of these 48 (1.6% 95% CI 0.8%-2.4%) died within three months of starting treatment, while a further 125 (4.2% 95% CI 2.1%-6.6%) were LTFU giving an attrition rate of 5.7% (95% CI 3.3%-8.6%). Tuberculosis was the most common comorbidity associated with high early mortality and high LTFU. Organizational culture, specifically an adhocratic type was found to be associated with low early mortality and low LTFU of patients enrolled for HIV care (P = 0.034).ConclusionThe use of ART clinical guidelines in a decentralized health systems are not sufficient to achieve required service delivery outcomes. The attrition rate above would mean 85,000 Kenyans missing care based on current HIV disease burden figures. Deliberate efforts to improve individual health facility leadership and inculcate an adhocratic culture may lower mortality and morbidity associated with initiating ART.

Project description:IntroductionHypertensive disorders of pregnancy (HDP) are a leading cause of global perinatal (fetal and neonatal) and maternal morbidity and mortality. We sought to describe HDP and determine the magnitude and risk factors for adverse perinatal and maternal outcomes among women with HDP in southwestern Uganda.MethodsWe prospectively enrolled pregnant women admitted for delivery and diagnosed with HDP at a tertiary referral hospital in southwestern Uganda from January 2019 to November 2019, excluding women with pre-existing hypertension. The participants were observed and adverse perinatal and maternal outcomes were documented. We used multivariable logistic regression models to determine independent risk factors associated with adverse perinatal and maternal outcomes.ResultsA total of 103 pregnant women with a new-onset HDP were enrolled. Almost all women, 93.2% (n = 96) had either pre-eclampsia with severe features or eclampsia. The majority, 58% (n = 60) of the participants had an adverse perinatal outcome (36.9% admitted to the neonatal intensive care unit (ICU), 20.3% stillbirths, and 1.1% neonatal deaths). Fewer participants, 19.4% (n = 20) had an adverse maternal outcome HELLP syndrome (7.8%), ICU admission (3%), and postpartum hemorrhage (3%). In adjusted analyses, gestational age of < 34 weeks at delivery and birth weight <2.5kg were independent risk factors for adverse perinatal outcomes while referral from another health facility and eclampsia were independent risk factors for adverse maternal outcomes.ConclusionAmong women with HDP at our institution, majority had preeclampsia with severe symptoms or eclampsia and an unacceptably high rate of adverse perinatal and maternal outcomes; over a fifth of the mothers experiencing stillbirth. This calls for improved antenatal surveillance of women with HDP and in particular improved neonatal and maternal critical care expertise at delivering facilities. Earlier detection and referral, as well as improvement in initial management at lower level health units and on arrival at the referral site is imperative.

Project description:BackgroundThere have been few studies about the basis on which women in developing regions evaluate and choose traditional rather than western maternal care. This qualitative study explores the socio-cultural perceptions of complications associated with pregnancy and childbirth and how these perceptions influence maternal health and care-seeking behaviours in Kenya.MethodsKalenjin women (n = 42) aged 18-45 years, who were pregnant or had given birth within the last 12 months, were interviewed. A semi-structured interview guide was used for data collection. A further nine key informant interviews with Traditional Birth Attendants (TBAs) who were also herbalists (n = 6), community health workers (CHWs) (n = 3) and a Maternal and Child Health (MCH) nursing officer (n = 1) were conducted. The data were analysed using MAXQDA12 software and categorised, thematised and analysed based on the symbolic dimensions of Helman's (2000) ill-health causation aetiologies model.ResultsPregnancy complications are perceived as the consequence of pregnant women not observing culturally restricted and recommended behaviour during pregnancy, including diet; physical activities; evil social relations and spirits of the dead. These complications are considered to be preventable by following a restricted and recommended diet, and avoiding heavy duties, funerals, killing of animals and eating meat of animal carcasses, as well as restricting geographical mobility, and use of herbal remedies to counter evil and prevent complications.ConclusionDelay in deciding to seek maternal care is a result of women's failure to recognise symptoms and maternal health problems as potential hospital cases, and this failure stems from culturally informed perceptions of symptoms of maternal morbidity and pregnancy complications that differ significantly from biomedical interpretations. Some of the cultural maternal care and remedies adopted to prevent pregnancy complications, such as restriction of diet and social mobility, may pose risks to the pregnant woman's health and access to health facilities whereas other remedies such as restricting consumption of meat from animal carcasses and heavy duties, as well as maintaining good social relations, are cultural adaptive mechanisms that indirectly control the transmission of disease and improve maternal health, and thus should not be considered to be exclusively folk or primitive.

Project description:ObjectiveTo evaluate whether urinary concentrations of organophosphate flame retardant (PFR) metabolites are associated with pregnancy loss among women conceiving with assisted reproductive technology (ART).DesignProspective preconception cohort of subfertile women.SettingAcademic hospital fertility center in Boston, Massachusetts.Patient(s)A total of 155 women conceiving 179 pregnancies with ART.Intervention(s)None. Mean exposure to each of five PFR metabolites was estimated by averaging the specific-gravity adjusted natural log concentrations from two urine samples collected during the ART cycle of conception.Main outcome measure(s)Adjusted risk ratios (RRs) and 95% confidence intervals (CIs) for biochemical and total pregnancy loss (all losses <20 weeks' gestation) by quartiles of PFR metabolite concentrations were estimated using a repeated measures log-binomial model, accounting for multiple pregnancies per woman.Result(s)Of the 179 pregnancies, 31% ended in pregnancy loss (12% in biochemical loss). Among the three metabolites with high detection frequency [bis(1,3-dichloro-2-propyl) phosphate (BDCIPP), diphenyl phosphate (DPHP), and isopropylphenyl phenyl phosphate (ip-PPP)], an increased risk of biochemical loss was observed for women with DPHP concentrations in the fourth vs. first quartile (RR 1.64; 95% CI 0.61-4.39). Also found was an elevated risk of biochemical pregnancy loss among women in the highest quartile of the molar sum of urinary PFR metabolites compared with the lowest (RR 1.89; 95% CI 0.64-5.58). Urinary concentrations of ip-PPP and BDCIPP were not associated with either outcome.Conclusion(s)Among subfertile women, urinary DPHP metabolite concentrations measured during the ART cycle of conception may be associated with early pregnancy loss. Although this study is uniquely designed to investigate early markers of pregnancy success and maintenance, the small sample size likely contributed to imprecision. Given their increasing use as replacement chemicals for traditional flame retardants, exposure to PFRs may increase, and more studies will be needed to investigate their potential to impact pregnancy and reproduction.

Project description:IntroductionRetention in HIV care and adherence to antiretroviral therapy (ART) during pregnancy and postpartum for women living with HIV (WLWH) are necessary to optimize health outcomes for women and infants. The objective of this study was to evaluate the impact of two evidenced-based behavioural interventions on postpartum adherence and retention in WLWH in Kenya.MethodsThe Mother-Infant Visit Adherence and Treatment Engagement (MOTIVATE) study was a cluster-randomized trial enrolling pregnant WLWH from December 2015 to August 2017. Twenty-four health facilities in southwestern Kenya were randomized to: (1) standard care (control), (2) text-messaging, (3) community-based mentor mothers (cMM) or (4) text-messaging and cMM. Primary outcomes included retention in care and ART adherence at 12 months postpartum. Analyses utilized generalized estimating equations and competing risks regression. Per-protocol analyses examined differences in postpartum retention for women with high versus low levels of exposure to the interventions.ResultsWe enrolled 1331 pregnant WLWH (mean age 28 years). At 12 months postpartum, 1140 (85.6%) women were retained in care, 96 women (7.2%) were lost-to-follow-up (LTFU) and 95 (7.1%) were discontinued from the study. In intention-to-treat analyses, the relative risk of being retained at 12-months postpartum was not significantly higher in the intervention arms versus the control arm. In time-to-event analysis, the cMM and text arm had significantly lower rates of LTFU (hazard ratio 0.44, p = 0.019). In per-protocol analysis, the relative risk of 12-month postpartum retention was 24-29% higher for women receiving at least 80% of the expected intervention compared to the control arm; text message only risk ratio (RR) 1.24 (95% confidence interval [CI] 1.16-1.32, p<0.001), cMM only RR 1.29 (95% CI 1.21-1.37, p<0.001) and cMM plus text RR 1.29 (1.21-1.37, p<0.001). Women LTFU were younger (p<0.001), less likely to be married (p<0.001) and more likely to be newly diagnosed with HIV during pregnancy (p<0.001). Self-reported ART adherence did not vary by study arm.ConclusionsBehavioural interventions using peer support and text messages did not appear to improve 12-month postpartum retention and adherence in intention-to-treat analyses. Higher levels of exposure to the interventions may be necessary to achieve the desired effects.
