Single-center serological surveillance of SARS-CoV-2 in pregnant patients presenting to labor and delivery. Int J Gynaecol Obstet 2023; 160:874-879. [PMID: 36416412 DOI: 10.1002/ijgo.14587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 10/18/2022] [Accepted: 11/11/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To measure maternal/fetal SARS-CoV-2 antibody levels. METHODS A prospective observational study of eligible parturients admitted to the hospital for infant delivery was conducted between April and September 2020. SARS-CoV-2 antibody levels were measured in maternal and umbilical cord specimens using an in-house ELISA based on the receptor-binding domain (RBD) of the spike protein. Among SARS-CoV-2 seropositive patients, spike RBD antibody isotypes (IgG, IgM, and IgA) and ACE2 inhibiting antibodies were measured. RESULTS In total, 402 mothers were enrolled and spike RBD antibodies in 388 pregnancies were measured (336 maternal and 52 cord specimens). Of them, 19 were positive (15 maternal, 4 cord) resulting in a seroprevalence estimate of 4.8% (95% confidence interval 2.9-7.4). Of the 15 positive maternal specimens, all had cord blood tested. Of the 15 paired specimens, 14 (93.3%) were concordant. Four of the 15 pairs were from symptomatic mothers, and all four showed high spike-ACE2 blocking antibody levels, compared to only 3 of 11 (27.3%) from asymptomatic mothers. CONCLUSION A variable antibody response to SARS-CoV-2 in pregnancy among asymptomatic infections compared to symptomatic infections was found, the significance of which is unknown. Although transfer of transplacental neutralizing antibodies occurred, additional research is needed to determine how long maternal antibodies can protect the infant against SARS-CoV-2 infection.

Kasede AN, Tylleskär T, Mukunya D, Tumuhamye J, Ndeezi G, Arach AAO, Waako P, Tumwine JK. Incidence of home delivery among women living with HIV in Lira, Northern Uganda: a prospective cohort study. BMC Pregnancy Childbirth 2021; 21:763. [PMID: 34758766 PMCID: PMC8579617 DOI: 10.1186/s12884-021-04222-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 10/13/2021] [Indexed: 11/11/2022] Open
Abstract
Background Home delivery has been associated with mother-to-child transmission of HIV and remains high among HIV-infected women. Predictors for home delivery in the context of HIV have not been fully studied and understood in Northern Uganda. We therefore aimed to find out the incidence and risk factors for home delivery among women living with HIV in Lira, Northern Uganda. Methods This prospective cohort study was conducted between August 2018 and January 2020 in Lira district, Northern Uganda. A total of 505 HIV infected women receiving antenatal care at Lira regional referral hospital were enrolled consecutively and followed up at delivery. We used a structured questionnaire to obtain data on exposures which included: socio-demographic, reproductive-related and HIV-related characteristics. Data was analysed using Stata version 14.0 (StataCorp, College Station, Texas, U.S.A.). We estimated adjusted risk ratios using Poisson regression models to ascertain risk factors for the outcome of interest which was home delivery (which is delivering an infant outside a health facility setting under the supervision of a non-health worker). Results The incidence of home delivery among women living with HIV was 6.9% (95%CI: 4.9–9.5%). Single women were more likely to deliver at home (adjusted risk ratio = 4.27, 95%CI: 1.66–11). Women whose labour started in the night (night time onset of labour ARR = 0.39, 95%CI: 0.18–0.86) and those that were adherent to their ART (ARR = 0.33, 95%CI: 0.13–0.86) were less likely to deliver at home. Conclusion Home delivery remains high among women living with HIV especially those that do not have a partner. We recommend intensified counselling on birth planning and preparedness in the context of HIV and PMTCT especially for women who are: separated, divorced, widowed or never married and those that are not adherent to their ART.

Barriers and enablers of adherence to infant nevirapine prophylaxis against HIV 1 transmission among 6-week-old HIV exposed infants: A prospective cohort study in Northern Uganda. PLoS One 2020; 15:e0240529. [PMID: 33057393 PMCID: PMC7561159 DOI: 10.1371/journal.pone.0240529] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Accepted: 09/28/2020] [Indexed: 11/19/2022] Open
Abstract
Background Sub-optimal adherence to infant prophylaxis has been associated with mother-to-child-transmission of HIV. However, the factors associated have not been well characterised in different settings. This study describes barriers and enablers of adherence to infant prophylaxis among 6-week-old HIV exposed infants in Lira district, Northern Uganda. Methods This prospective cohort study was conducted from 2018–2020 at the PMTCT clinic at Lira Regional Referral Hospital and included 472 mother-infant pairs. HIV-infected pregnant women were recruited, followed up at delivery and 6 weeks postpartum. We used a structured questionnaire to obtain data on socio-demographic, reproductive-related, HIV-related characteristics and adherence. Data were analysed using Stata to estimate adjusted risk ratios using Poisson regression models to ascertain barriers and enablers of adherence to infant nevirapine prophylaxis. Results Barriers to infant adherence are maternal characteristics including: younger age (≤20 years adjusted risk ratio (ARR) = 1.55; 95% CI: 1.1–2.2), missing a viral load test during pregnancy (ARR: 1.4; 95% CI: 1.1–1.7) and not receiving nevirapine syrup for the baby after childbirth (ARR = 6.2; 95% CI: 5.1–7.6). Enablers were: having attained ≥14 years of schooling (ARR = 0.7; 95% CI: 0.5–0.9), taking a nevirapine-based regimen (ARR = 0.6; 95% CI: 0.4–0.9), long-term ART (≥ 60 months ARR = 0.75; 95% CI: 0.6–0.9), accompanied by a husband to hospital during labour and childbirth (ARR = 0.5; 95% CI: 0.4–0.7) and labour starting at night (ARR = 0.7; 95% CI: 0.6–0.8). Conclusion and recommendations Despite mothers receiving nevirapine syrup from the health workers for the infant, non-adherence rates still prevail at 14.8%. The health system needs to consider giving HIV infected pregnant women the nevirapine syrup before birth to avoid delays and non-adherence. There is need to pay particular attention to younger women and those who recently started ART.

Abstract
BACKGROUND HIV-status disclosure is widely encouraged by counseling services, in part because it is thought to improve antiretroviral therapy (ART) adherence and thus HIV viral suppression. However, few longitudinal studies have examined the impact of disclosure on HIV viral load (VL) during pregnancy and postpartum. METHODS We explored these associations among 1187 women living with HIV, enrolled between March 2013 and June 2014 in Cape Town, South Africa. RESULTS Among women who tested HIV-positive before pregnancy, we observed no association between disclosure and VL at entry into antenatal care among those already on ART, nor at delivery and 12 months postpartum among those initiating ART. Among women who tested HIV-positive during pregnancy and initiated ART subsequently, disclosure to a male partner was associated with a reduced risk of VL ≥50 copies/mL at delivery (adjusted risk ratio: 0.56; 95% confidence interval: 0.31 to 1.01). After stratification by relationship status, this association was only observed among women who were married and/or cohabiting. In addition, disclosure to ≥1 family/community member was associated with a reduced risk of VL ≥50 copies/mL at 12 months postpartum (adjusted risk ratio: 0.69; 95% confidence interval: 0.48 to 0.97) among newly-diagnosed women. CONCLUSIONS These findings suggest that the impact of disclosure on VL is modified by 3 factors: (1) timing of HIV diagnosis (before vs. during the pregnancy); (2) relationship to the person(s) to whom women disclose; and (3) in the case of disclosure to a male partner, relationship status. Counseling about disclosure may be most effective if tailored to individual women's circumstances.

Abstract
Prevention of mother-to-child transmission of HIV (PMTCT) can virtually eliminate vertical HIV transmission, yet more than 160 000 children were newly infected with HIV in 2016. We conducted a pooled analysis of national household surveys from 26 sub-Saharan African countries and calculated PMTCT coverage and access using unconditional and conditional likelihoods. Logistic regression analysis adjusted for country of residence was used to measure the association between socio-demographic factors and PMTCT coverage. The largest loss in the PMTCT cascade access occurred at being offered a HIV test at an antenatal care (ANC) clinic visit, with only 62.6% of women visiting an ANC clinic being offered a HIV test. Logistic regression analysis adjusted for country of residence indicated that completing primary school was associated with a higher likelihood of completing each step in the PMTCT cascade, including being offered a HIV test [odds ratio 2.18 (95% CI: 2.09-2.26)]. Urban residence was associated with a higher likelihood of completing each step in the PMTCT cascade, including being offered a HIV test [odds ratio 2.23 (95% CI: 2.15-2.30)]. To increase progression through the PMTCT cascade, policy-makers should target the likelihood an ANC client is offered a HIV test and the likelihood of facility delivery, steps where access is the lowest. Low educational attainment women and women in rural areas appear to have the lowest coverage in the cascade, suggesting that policy-makers target these individuals.

Abstract
BACKGROUND / OBJECTIVES Detectable HIV viral load among HIV-infected pregnant women remains a public health threat. We aimed to determine factors associated with detectable viral load among HIV-infected pregnant women in Lira, Northern Uganda. METHODS We conducted a cross-sectional survey among 420 HIV-infected pregnant women attending Lira Regional Referral Hospital using a structured questionnaire and combined it with viral load tests from Uganda National Health Laboratories. We conducted multivariable logistic regression while adjusting for confounders to determine the factors associated with detectable viral load and we report adjusted odds ratios and proportion of women with viral load less than 50 copies/ml and above 1000 copies, respectively. RESULTS The prevalence of detectable viral load (>50 copies/ml) was 30.7% (95%CI: 26.3% - 35.4%) and >1000 copies/ml was 8.1% (95% CI: 5.7% - 11.1%). Factors associated with detectable viral load were not belonging to the Lango ethnicity (adjusted odds ratio = 1.92, 95%CI: 1.05 - 3.90) and taking a second-line (protease inhibitor-based) regimen (adjusted odds ratio = 4.41, 95%CI: 1.13 - 17.22). CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS HIV-infected pregnant women likely to have detectable viral load included those taking a protease inhibitor-based regimen and those who were not natives of Lira. We recommend intensified clinical and psychosocial monitoring for medication compliance among HIV-infected pregnant women that are likely to have a detectable viral load to significantly lower the risk of vertical transmission of HIV in Lira specifically those taking a protease inhibitor-based regimen and those who are non-natives to the study setting. Much as the third 90% of the global UNAIDS 90-90-90 target has been achieved, the national implementation of PMTCT guidelines should be tailored to its contextual needs.

Abstract
Care for low birthweight (LBW) infants can contribute to psychological difficulties and stigma among mothers living with HIV, creating challenges for antiretroviral therapy (ART) adherence and retention in HIV care. We explored how caring for LBW infants affects maternal ART adherence and retention in care. We conducted 30 in-depth interviews with postpartum women living with HIV in Accra, Ghana: 15 with LBW infants and 15 with normal birthweight (NBW) infants. Compared to mothers with NBW infants, mothers with LBW infants described how caring for their newborns led to increased caregiver burden, prolonged hospital stays, and stigma-contributing to incomplete ART adherence and missed clinical appointments. For a few women, care for LBW infants created opportunities for re-engagement in HIV care and motivation to adhere to ART. Results suggest women living with HIV and LBW babies in Ghana face increased challenges that impact their adherence to care and ART.

Abstract
Disclosure of HIV status remains one of the major challenges to the effectiveness of the prevention of mother to child transmission of HIV in rural areas in South Africa. This study aimed at assessing the determinants of HIV status disclosure among HIV infected pregnant women who have disclosed their HIV status to someone, as well as among those who have disclosed to their partners. Cross-sectional data was collected from 673 HIV sero-positive pregnant women receiving antenatal care services at 12 Community Health Centers in Mpumalanga province. Results indicated that over two-thirds (72.1%) disclosed their status to someone, while just over half (58.4%) disclosed to their partners. Multivariate analysis showed that both disclosure of ones HIV status to someone and to their male partners was significantly associated with increase in antiretroviral therapy (ART) adherence, the known HIV positive status of their partner, and male involvement during pregnancy. Participants who were diagnosed HIV positive during this current pregnancy were less likely to disclose their HIV status to someone. Non-disclosure during current pregnancy highlights a need for interventions that will encourage disclosure among HIV positive women, with a particular focus on those who are newly diagnosed. The findings also need to integrate male partner involvement and partner disclosure during pregnancy.

Abstract
Sub-Saharan Africa (SSA) accounts for more than two thirds of the world's HIV infection. Despite scaled-up prevention of mother-to-child transmission of HIV (PMTCT) programmes, mother to child transmission of HIV (MTCT) continues to escalate. We describe the challenges faced by PMTCT in MTCT in SSA. The study reviewed articles and reports published online. The most common barriers and challenges were non-disclosure of HIV status, late initiation of ARVs treatment/adherence, STIs screening, long clinics waiting time, non-involvement of men in ANC/PMTCT, infant feeding methods and sensitization of community members on ANC/PMTCT programmes. The study highlights the need to expand PMTCT coverage and the implementation of the 90-90-90 programme toward MTCT elimination in SSA. That is " ≥90% of pregnant and breast-feeding mothers must know their HIV status; ≥90% of those that are positive are enrolled on ARVs treatment and care; ≥90% of those on ARVs treatment and care are virally suppressed.

Abstract
BACKGROUND Low rates of maternal healthcare service utilization, including facility delivery, may impede progress in the prevention of mother-to-child transmission of HIV (PMTCT) and in reducing maternal and infant mortality. The MoMent (Mother Mentor) study investigated the impact of structured peer support on early infant diagnosis presentation and postpartum maternal retention in PMTCT care in rural Nigeria. This paper describes baseline characteristics and correlates of facility delivery among MoMent study participants. METHODS HIV-positive pregnant women were recruited at 20 rural Primary Healthcare Centers matched by antenatal care clinic volume, client HIV prevalence, and PMTCT service staffing. Baseline and delivery data were collected by participant interviews and medical record abstraction. Multivariate logistic regression with generalized estimating equation analysis was used to evaluate for correlates of facility delivery including exposure to structured (closely supervised Mentor Mother, intervention) vs unstructured (routine, control) peer support. RESULTS Of 497 women enrolled, 352 (71%) were between 21 and 30 years old, 319 (64%) were Christian, 245 (49%) had received secondary or higher education, 402 (81%) were multigravidae and 299 (60%) newly HIV-diagnosed. Delivery data was available for 445 (90%) participants, and 276 (62%) of these women delivered at a health facility. Facility delivery did not differ by type of peer support; however, it was positively associated with secondary or greater education (aOR 1.9, CI 1.1-3.2) and Christian affiliation (OR 1.4, CI 1.0-2.0) and negatively associated with primigravidity (OR 0.5; 0.3-0.9) and new HIV diagnosis (OR 0.6, CI 0.4-0.9). CONCLUSIONS Primary-level or lesser-educated HIV-infected pregnant women and those newly-diagnosed and primigravid should be prioritized for interventions to improve facility delivery rates and ultimately, healthy outcomes. Incremental gains in facility delivery from structured peer support appear limited, however the impact of duration of pre-delivery support needs further investigation. Religious influences on facility delivery and on general maternal healthcare service utilization need to be further explored.

Underutilisation of routinely collected data in the HIV programme in Zambia: a review of quantitatively analysed peer-reviewed articles. Health Res Policy Syst 2017; 15:51. [PMID: 28610616 PMCID: PMC5470192 DOI: 10.1186/s12961-017-0221-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2016] [Accepted: 05/30/2017] [Indexed: 01/23/2023] Open
Abstract
Background The extent to which routinely collected HIV data from Zambia has been used in peer-reviewed published articles remains unexplored. This paper is an analysis of peer-reviewed articles that utilised routinely collected HIV data from Zambia within six programme areas from 2004 to 2014. Methods Articles on HIV, published in English, listed in the Directory of open access journals, African Journals Online, Google scholar, and PubMed were reviewed. Only articles from peer-reviewed journals, that utilised routinely collected data and included quantitative data analysis methods were included. Multi-country studies involving Zambia and another country, where the specific results for Zambia were not reported, as well as clinical trials and intervention studies that did not take place under routine care conditions were excluded, although community trials which referred patients to the routine clinics were included. Independent extraction was conducted using a predesigned data collection form. Pooled analysis was not possible due to diversity in topics reviewed. Results A total of 69 articles were extracted for review. Of these, 7 were excluded. From the 62 articles reviewed, 39 focused on HIV treatment and retention in care, 15 addressed prevention of mother-to-child transmission, 4 assessed social behavioural change, and 4 reported on voluntary counselling and testing. In our search, no articles were found on condom programming or voluntary male medical circumcision. The most common outcome measures reported were CD4+ count, clinical failure or mortality. The population analysed was children in 13 articles, women in 16 articles, and both adult men and women in 33 articles. Conclusion During the 10 year period of review, only 62 articles were published analysing routinely collected HIV data in Zambia. Serious consideration needs to be made to maximise the utility of routinely collected data, and to benefit from the funds and efforts to collect these data. This could be achieved with government support of operational research and publication of findings based on routinely collected Zambian HIV data.

Abstract
BACKGROUND Early detection of pediatric HIV through uptake of infant HIV testing is critical for access to treatment and child survival. While structural barriers have been well described, a greater understanding of social and behavioral factors that may relate to maternal uptake of early infant HIV testing services is urgently needed. The aim of this study was to explore how gender power dynamics within couples affect HIV-positive women's uptake of early infant HIV testing at a large health center in Lusaka, Zambia. METHODS In 2014, 320 HIV-positive married postpartum women were recruited at a large public health facility in Lusaka to participate in a cross-sectional survey. Data on uptake of early infant HIV testing by 4-6 weeks of age was collected through medical records. Simple and multiple logistic regression models determined significant predictors of maternal uptake of early infant HIV testing. RESULTS In the adjusted model, uptake of early infant HIV testing was associated with female-directed emotional intimate partner violence (aOR 0.41; 95% CI 0.21-0.79; p < 0.01), HIV status disclosure to the male partner (aOR 13.73, 95% CI 3.59-52.49, p < 0.001), and maternal postpartum ART adherence (aOR 2.28, 95% CI 1.15-4.55, p < 0.05). CONCLUSIONS Domestic relationship dynamics, including emotional violence and HIV status disclosure to the male partner, may play an important role in maternal uptake of early infant HIV testing. These findings provide additional evidence for the link between intimate partner violence against women and poor HIV-related health outcomes. Programs that adequately screen for and address various forms of intimate partner violence within the context of prevention of mother-to-child transmission are recommended.

Abstract
Background In developing countries, facility-based delivery is recommended for maternal and neonatal health, and for prevention of mother-to-child HIV transmission (PMTCT). However, little is known about whether or not learning one’s HIV status affects one’s decision to deliver in a health facility. We examined this association in Zimbabwe. Methods We analyzed data from a 2012 cross-sectional community-based serosurvey conducted to evaluate Zimbabwe’s accelerated national PMTCT program. Eligible women (≥16 years old and mothers of infants born 9–18 months before the survey) were randomly sampled from the catchment areas of 157 health facilities in five of ten provinces. Participants were interviewed about where they delivered and provided blood samples for HIV testing. Results Overall 8796 (77 %) mothers reported facility-based delivery; uptake varied by community (30–100 %). The likelihood of facility-based delivery was not associated with maternal HIV status. Women who self-reported being HIV-positive before delivery were as likely to deliver in a health facility as women who were HIV-negative, irrespective of when they learned their status - before (adjusted prevalence ratio (PRa) = 1.04, 95 % confidence interval (CI) = 1.00–1.09) or during pregnancy (PRa = 1.05, 95 % CI = 1.01–1.09). Mothers who had not accessed antenatal care or tested for HIV were most likely to deliver outside a health facility (69 %). Overall, however 77 % of home deliveries occurred among women who had accessed antenatal care and were HIV-tested. Conclusions Uptake of facility-based delivery was similar among HIV-infected and HIV-uninfected mothers, which was somewhat unexpected given the substantial technical and financial investment aimed at retaining HIV-positive women in care in Zimbabwe.

Abstract
L’épidémie du Virus de l'Immunodéficience Humaine en milieu pédiatrique est surtout le résultat de la transmission mère-enfant. Notre étude a pour objectif de décrire l'efficacité de la prévention de la transmission mère-enfant du Virus de l'Immunodéficience Humaine par le protocole OMS 2010 (Option A et trithérapie) au centre médical saint Camille de Ouagadougou. Nous avons mené une étude d'une cohorte d'enfants suivis dans le cadre de la prévention de la transmission mère-enfant du Virus de l'Immunodéficience Humaine au centre médical saint Camille de Ouagadougou sur une période de 2 ans allant du 1er Janvier 2012 au 31 Décembre 2013. Nous avons obtenu l'accord de 4900 femmes enceintes pour le dépistage de l'infection du Virus de l'Immunodéficience Humaine et 238 gestantes ont été diagnostiquées séropositives soit 4,86% de séroprévalence. Les femmes étaient surtout infectées par le Virus de l'Immunodéficience Humaine avec de type I (95,38%)). La majorité était sous trithérapie (74,3%) et (25,7%) sous prophylaxie (option A). Les nouveau-nés (92,5%) ont reçu un traitement antirétroviral à base de névirapine dans les 72 heures après la naissance. L'allaitement sécurisé a été appliquée dans 78% des cas. Le taux global de transmission mère-enfant du VIH était de 3,6% avec 3% de transmission chez les enfants nés de mères sous trithérapie antirétrovirale et 6,3% dans les cas de prophylaxie antirétrovirale. Le facteur de risque de transmission a été le long délai du début d'administration des antirétroviraux chez le nouveau-né. La mortalité infantile à un an était de 3,5%. Cette étude a révélé l'efficacité de l'Option A et conforté celle de la trithérapie, le passage à l'Option B+ serait donc plus bénéfique.

Longitudinal adherence to antiretroviral drugs for preventing mother-to-child transmission of HIV in Zambia. BMC Pregnancy Childbirth 2015; 15:258. [PMID: 26459335 PMCID: PMC4603915 DOI: 10.1186/s12884-015-0697-7] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2015] [Accepted: 10/06/2015] [Indexed: 12/02/2022] Open
Abstract
Background Adherence to antiretroviral (ARV) drugs is essential for eliminating new pediatric infections of human immunodeficiency virus (HIV). Since the Zambian government revised the national guidelines based on option A (i.e., maternal zidovudine and infant ARV prophylaxis) of the World Health Organization’s 2010 guidelines, no studies have assessed adherence to ARVs during pregnancy up to the postpartum period. This study aimed to examine adherence to ARVs and identify the associated risk factors. Methods A prospective cohort study was conducted in the Chongwe district from June 2011 to January 2014. Self-reported adherence to ARVs was examined during pregnancy and at one week, six weeks, and 24 weeks postpartum among 321 HIV-positive women. The probability of remaining adherent to ARVs was estimated using the Kaplan-Meier method, and the risk factors for non-adherence were identified using the Cox proportional hazard regressions—treating loss to follow-up as non-adherence. The statuses of HIV in HIV-exposed infants were assessed in January 2014. Results During the study period, 326 infants were born to HIV-positive women, 262 (80.4 %) underwent HIV testing, and 11 (3.4 %) had their HIV infection detected at the time that they had the latest HIV testing as of January 2014. The ARV adherence rate was 82.5 % during pregnancy, 84.2 % at one week postpartum, 81.5 % at six weeks postpartum, and 70.5 % at 24 weeks postpartum. The probability of remaining adherent to ARVs was 0.61 at day 50, 0.35 at day 100, 0.18 at day 200, and 0.06 at day 300. Attending a referral health center (HC) was a risk factor for non-adherence compared with attending rural HCs that provided HIV care/treatment (adjusted hazard ratio [aHR] 0.71, 95 % confidence interval [CI] 0.57–0.88) and those that did not provide HIV care/treatment (aHR 0.58, 95 % CI 0.46–0.74). A new diagnosis of HIV infection compared to a known HIV-positive status before pregnancy was another risk factor for non-adherence (aHR 1.24, 95 % CI 1.03–1.50). Conclusions Maintaining adherence to ARVs through pregnancy to the postpartum period remains a crucial challenge in Zambia. To maximize the treatment benefits, adherence to ARVs and retention in care should be improved at all health facilities.

Abstract
BACKGROUND Childbirth at health facilities is an important strategy to reduce maternal morbidity and mortality, improve fetal outcomes, and reduce mother-to-child transmission of HIV. Although access to antenatal care in Kenya is high (>90%), less than half of births occur at health facilities. This analysis aims to assess correlates of facility delivery among recently pregnant HIV-infected women participating in a community-based survey, and to determine whether these correlates were unique when compared to HIV-uninfected women from the same region. METHODS Women residing in the Kenya Medical Research Institute/Centers for Disease Control and Prevention Health and Demographic Surveillance System, and who had delivered an infant in the previous year were visited at home in 2011. Consenting mothers answered a questionnaire assessing demographics, place of delivery, utilization of prevention of mother-to-child HIV transmission (PMTCT) services, and stigma indicators. Known HIV-positive women were purposively oversampled. Chi-square tests of proportions and multivariate logistic regression, stratified by HIV status, were performed to assess correlates of facility delivery. RESULTS Overall, 101 (46.8%) HIV-infected and 127 (39.9%) HIV-uninfected women delivered at health facilities. Among HIV-infected women, cost (42.8%), distance (18.8%) and fear of harsh treatment (15.2%) were primary disincentives for facility delivery; 2.9% noted fear of HIV testing was a disincentive. HIV-infected women who delivered at facilities had higher education (p = 0.04) and socioeconomic status (p < 0.005), initiated antenatal care (ANC) earlier (4.9 vs. 5.4 months, p = 0.016), were more likely to know partner's HIV status (p = 0.016), report satisfaction with delivery care (p = 0.001) and use antiretrovirals (87.1% vs. 77.4%, p = 0.063) compared to those with non-facility delivery. Stigma indicators were not associated with delivery location. Similar cofactors of facility delivery were noted among uninfected women. CONCLUSIONS Utilization of facility delivery remains low in Kenya and poses a challenge to elimination of infant HIV and reduction of peripartum mortality. Cost, distance, and harsh treatment were cited as barriers and these need to be addressed programmatically. HIV-infected women with lower socioeconomic status and those who present late to ANC should be prioritized for interventions to increase facility delivery. Partner involvement may increase use of maternity services and could be enhanced by couples counseling.

Abstract
Supplemental Digital Content is Available in the Text. Background: In sub-Saharan Africa, women's disclosure of HIV-positive status to others may affect their use of services for prevention of mother-to-child transmission of HIV (PMTCT) of HIV and maternal and child health—including antenatal care, antiretroviral drugs (ARVs) for PMTCT, and skilled birth attendance. Methods: Using data from the Migori and AIDS Stigma Study conducted in rural Nyanza Province, Kenya, we compared the use of PMTCT and maternal health services for all women by HIV status and disclosure category (n = 390). Among HIV-infected women (n = 145), associations between disclosure of HIV-positive status and the use of services were further examined with bivariate and multivariate logistic regression analyses. Results: Women living with HIV who had not disclosed to anyone had the lowest levels of maternity and PMTCT service utilization. For example, only 21% of these women gave birth in a health facility, compared with 35% of HIV-negative women and 49% of HIV-positive women who had disclosed (P < 0.001). Among HIV-positive women, the effect of disclosure to anyone on ARV drug use [odds ratio (OR) = 5.8; 95% confidence interval (CI): 1.9 to 17.8] and facility birth (OR = 2.9; 95% CI: 1.4 to 5.7) remained large and significant after adjusting for confounders. Disclosure to a male partner had a particularly strong effect on the use of ARVs for PMTCT (OR = 7.9; 95% CI: 3.7 to 17.1). Conclusions: HIV-positive status disclosure seems to be a complex yet critical factor for the use of PMTCT and maternal health services in this setting. The design of interventions to promote such disclosure must recognize the impact of HIV-related stigma on disclosure decisions and protect women's rights, autonomy, and safety.

Abstract
Support to health programming has increasingly placed an emphasis on health systems strengthening. Integration of prevention of mother-to-child transmission (PMTCT) and maternal and newborn child health (MNCH) services has been one of the areas where there has been a shift from a siloed to a more integrated approach. The scale-up of anti-retroviral therapy has made services increasingly available while also bringing them closer to those in need. However, addressing supply side issues around the availability and quality of care at the health centre level alone cannot guarantee better results without a more explicit focus on access issues. Access to PMTCT care and treatment services is affected by a number of barriers which influence decisions of women to seek care. This paper reviews published qualitative and quantitative studies that look at demand side barriers to PMTCT services and proposes a categorisation of these barriers. It notes that access to PMTCT services as well as eventual uptake and retention in PMTCT care starts with access to MNCH in general. While poverty often prevents women, regardless of HIV status, from accessing MNCH services, women living with HIV who are in need of PMTCT services face an additional set of PMTCT barriers. This review proposes four categories of barriers to accessing PMTCT: social norms and knowledge, socioeconomic status, physiological status and psychological conditions. Social norms and knowledge and socioeconomic status stand out. Transport is the most frequently mentioned socioeconomic barrier. With regard to social norms and knowledge, non-disclosure, stigma and partner relations are the most commonly cited barriers. Some studies also cite physiological barriers. Barriers related to social norms and knowledge, socioeconomic status and physiology can all be affected by the mental and psychological state of the individual to create a psychological barrier to access. Increased coverage and uptake of PMTCT services can be achieved if policy makers and programme managers better understand the barriers that may prevent their potential target population from taking up and adhering to their services. The categorisation presented in this review provides further insight into the type of barriers that may exist .

Background Prevention of mother to child HIV transmission (PMTCT) remains a challenge in low and middle-income countries. Determinants of utilization occur – and often interact - at both individual and community levels, but most studies do not address how determinants interact across levels. Multilevel models allow for the importance of both groups and individuals in understanding health outcomes and provide one way to link the traditionally distinct ecological- and individual-level studies. This study examined individual and community level determinants of mother and child receiving PMTCT services in Tigray region, Ethiopia. Methods A multistage probability sampling method was used for this 2011 cross-sectional study of 220 HIV positive post-partum women attending child immunization services at 50 health facilities in 46 districts. In view of the nested nature of the data, we used multilevel modeling methods and assessed macro level random effects. Results Seventy nine percent of mothers and 55.7% of their children had received PMTCT services. Multivariate multilevel modeling found that mothers who delivered at a health facility were 18 times (AOR = 18.21; 95% CI 4.37,75.91) and children born at a health facility were 5 times (AOR = 4.77; 95% CI 1.21,18.83) more likely to receive PMTCT services, compared to mothers delivering at home. For every addition of one nurse per 1500 people, the likelihood of getting PMTCT services for a mother increases by 7.22 fold (AOR = 7.22; 95% CI 1.02,51.26), when other individual and community level factors were controlled simultaneously. In addition, district-level variation was low for mothers receiving PMTCT services (0.6% between districts) but higher for children (27.2% variation between districts). Conclusions This study, using a multilevel modeling approach, was able to identify factors operating at both individual and community levels that affect mothers and children getting PMTCT services. This may allow differentiating and accentuating approaches for different settings in Ethiopia. Increasing health facility delivery and HCT coverage could increase mother-child pairs who are getting PMTCT. Reducing the distance to health facility and increasing the number of nurses and laboratory technicians are also important variables to be considered by the government.

Abstract
Background Women’s ability to safely disclose their HIV-positive status to male partners is essential for uptake and continued use of prevention of mother-to-child transmission (PMTCT) services. However, little is known about the acceptability of potential approaches for facilitating partner disclosure. To lay the groundwork for developing an intervention, we conducted formative qualitative research to elicit feedback on three approaches for safe HIV disclosure for pregnant women and male partners in rural Kenya. Methods This qualitative acceptability research included in-depth interviews with HIV-infected pregnant women (n = 20) and male partners of HIV-infected women (n = 20) as well as two focus groups with service providers (n = 16). The participants were recruited at health care facilities in two communities in rural Nyanza Province, Kenya, during the period June to November 2011. Data were managed in NVivo 9 and analyzed using a framework approach, drawing on grounded theory. Results We found that facilitating HIV disclosure is acceptable in this context, but that individual participants have varying expectations depending on their personal situation. Many participants displayed a strong preference for couples HIV counseling and testing (CHCT) with mutual disclosure facilitated by a trained health worker. Home-based approaches and programs in which pregnant women are asked to bring their partners to the healthcare facility were equally favored. Participants felt that home-based CHCT would be acceptable for this rural setting, but special attention must be paid to how this service is introduced in the community, training of the health workers who will conduct the home visits, and confidentiality. Conclusion Pregnant couples should be given different options for assistance with HIV disclosure. Home-based CHCT could serve as an acceptable method to assist women and men with safe disclosure of HIV status. These findings can inform the design and implementation of programs geared at promoting HIV disclosure among pregnant women and partners, especially in the home-setting.

Barriers and facilitating factors to the uptake of antiretroviral drugs for prevention of mother-to-child transmission of HIV in sub-Saharan Africa: a systematic review. J Int AIDS Soc 2013; 16:18588. [PMID: 23870277 PMCID: PMC3717402 DOI: 10.7448/ias.16.1.18588] [Citation(s) in RCA: 283] [Impact Index Per Article: 25.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2013] [Revised: 05/10/2013] [Accepted: 06/19/2013] [Indexed: 11/19/2022] Open
Abstract
Objectives To investigate and synthesize reasons for low access, initiation and adherence to antiretroviral drugs by mothers and exposed babies for prevention of mother-to-child transmission (PMTCT) of HIV in sub-Saharan Africa. Methods A systematic literature review was conducted. Four databases were searched (Medline, Embase, Global Health and Web of Science) for studies conducted in sub-Saharan Africa from January 2000 to September 2012. Quantitative and qualitative studies were included that met pre-defined criteria. Antiretroviral (ARV) prophylaxis (maternal/infant) and combination antiretroviral therapy (ART) usage/registration at HIV care and treatment during pregnancy were included as outcomes. Results Of 574 references identified, 40 met the inclusion criteria. Four references were added after searching reference lists of included articles. Twenty studies were quantitative, 16 were qualitative and eight were mixed methods. Forty-one studies were conducted in Southern and East Africa, two in West Africa, none in Central Africa and one was multi-regional. The majority (n=25) were conducted before combination ART for PMTCT was emphasized in 2006. At the individual-level, poor knowledge of HIV/ART/vertical transmission, lower maternal educational level and psychological issues following HIV diagnosis were the key barriers identified. Stigma and fear of status disclosure to partners, family or community members (community-level factors) were the most frequently cited barriers overall and across time. The extent of partner/community support was another major factor impeding or facilitating the uptake of PMTCT ARVs, while cultural traditions including preferences for traditional healers and birth attendants were also common. Key health-systems issues included poor staff-client interactions, staff shortages, service accessibility and non-facility deliveries. Conclusions Long-standing health-systems issues (such as staffing and service accessibility) and community-level factors (particularly stigma, fear of disclosure and lack of partner support) have not changed over time and continue to plague PMTCT programmes more than 10 years after their introduction. The potential of PMTCT programmes to virtually eliminate vertical transmission of HIV will remain elusive unless these barriers are tackled. The prominence of community-level factors in this review points to the importance of community-driven approaches to improve uptake of PMTCT interventions, although packages of solutions addressing barriers at different levels will be important.

Abstract
Summary Adherence to antiretroviral therapy (ART) is crucial for effective treatment, but can be quite complex. Non-adherence can adversely affect treatment outcomes. Although many studies have been done on adherence in the general population, few have included HIV-positive pregnant and postpartum women in resource-constrained settings. This review assessed the evidence on adherence among these groups of women. A systematic search of databases was completed between June and July 2011. Both qualitative and quantitative studies were included. Eighteen studies from a total of 6622 satisfied the inclusion criteria that included inter alia facilitators and barriers to adherence. This review highlighted that there is still no consensus on the definition and measurement of adherence; also multiple factors can affect a woman's ability to adhere to ART. Some of the barriers and facilitators identified were similar in both the type of study (qualitative and quantitative) and among the various countries. Findings indicated that the few studies in this population are conducted primarily in resource-rich settings. Such paucity of information warrants urgent attention; thus targeted research is needed to provide insight on adherence within this population.

Abstract
Introduction Mother-to-Mother (M2M) or “Mentor Mother” programmes utilise HIV positive mothers to provide support and advice to HIV positive pregnant women and mothers of HIV exposed babies. Médecins Sans Frontières (MSF) supported a Mentor Mother programme in Bulawayo, Zimbabwe from 2009 to 2012; with programme beneficiaries observed to have far higher retention at 6–8 weeks (99% vs 50%, p<0.0005) and to have higher adherence to Prevention of Mother to Child Transmission (PMTCT) guidelines, compared to those not opting in. In this study we explore how the M2M progamme may have contributed to these findings. Methods In this qualitative study we used thematic analysis of in-depth interviews (n = 79). This study was conducted in 2 urban districts of Bulawayo, Zimbabwe’s second largest city. Results Interviews were completed by 14 mentor mothers, 10 mentor mother family members, 30 beneficiaries (women enrolled both in PMTCT and M2M), 10 beneficiary family members, 5 women enrolled in PMTCT but who had declined to take part in the M2M programme and 10 health care staff members. All beneficiaries and health care staff reported that the programme had improved retention and provided rich information on how this was achieved. Additionally respondents described how the programme had helped bring about beneficial behaviour change. Conclusions M2M programmes offer great potential to empower communities affected by HIV to catalyse positive behaviour change. Our results illustrate how M2M involvement may increase retention in PMTCT programmes. Non-disclosure to one’s partner, as well as some cultural practices prevalent in Zimbabwe appear to be major barriers to participation in M2M programmes.

Abstract
BACKGROUND Uptake of prevention of mother-to-child HIV transmission (PMTCT) programs remains challenging in sub-Saharan Africa because of multiple barriers operating at the individual or health facility levels. Less is known regarding the influence of program-level and contextual determinants. In this study, we explored the multilevel factors associated with coverage in single-dose nevirapine PMTCT programs. METHODS We analyzed aggregate routine data collected within the framework of the Viramune(®) Donation Programme (VDP) from 269 sites in 20 PMTCT programs and 15 sub-Saharan countries from 2002 to 2005. Site performance was measured using a nevirapine coverage ratio (NCR), defined as the reported number of women receiving nevirapine divided by the number of women who should have received nevirapine (observed HIV prevalence x number of women in antenatal care [ANC]). Data on program-level determinants were drawn from the initial application forms, and country-level determinants from the Demographic and Health Surveys (DHS) and the World Bank (World Development Indicators). Multilevel linear mixed models were used to identify independent factors associated with NCR at the site-, program- and country-level. RESULTS Of 283,410 pregnant women attending ANC in the included sites, 174,312 women (61.5%) underwent HIV testing after receiving pre-test counselling, of whom 26,700 tested HIV positive (15.3%), and 22,591 were dispensed NVP (84.6%). Site performance was highly heterogeneous between and within programs. Mean NCR by site was 43.8% (interquartile range: 19.1-63.9). Multilevel analysis identified higher HIV prevalence (Beta coefficient: 25.1, 95% confidence interval [CI] 18.7 to 31.6), higher proportion of persons with knowledge of PMTCT (8.3; CI 0.5 to 16.0), higher health expenditure as a proportion of Gross Domestic Product (3.9 per %; CI 2.0 to 5.8) and lower percentage of rural population (-0.7 per %; CI -1.0 to -0.5) as significant country-level predictors of higher NCR at the p<0.05 level. A medium ANC monthly activity (30-100/month) was the only site-level predictor found (-7.6; CI -15.1 to -0.1). CONCLUSIONS Heterogeneity of nevirapine coverage between sites and programs was high. Multilevel analysis identified several significant contextual determinants, which may warrant additional research to further define important multi-level and potentially modifiable determinants of performance of PMTCT programs.

Abstract
OBJECTIVE To estimate antiretroviral therapy (ART) adherence rates during pregnancy and postpartum in high-income, middle-income, and low-income countries. DESIGN Systematic review and meta-analysis. METHODS MEDLINE, EMBASE, SCI Web of Science, NLM Gateway, and Google scholar databases were searched. We included all studies reporting adherence rates as a primary or secondary outcome among HIV-infected pregnant women. Two independent reviewers extracted data on adherence and study characteristics. A random-effects model was used to pool adherence rates; sensitivity, heterogeneity, and publication bias were assessed. RESULTS Of 72 eligible articles, 51 studies involving 20 153 HIV-infected pregnant women were included. Most studies were from United States (n = 14, 27%) followed by Kenya (n = 6, 12%), South Africa (n = 5, 10%), and Zambia (n = 5, 10%). The threshold defining good adherence to ART varied across studies (>80, >90, >95, 100%). A pooled analysis of all studies indicated a pooled estimate of 73.5% [95% confidence interval (CI) 69.3-77.5%] of pregnant women who had adequate (>80%) ART adherence. The pooled proportion of women with adequate adherence levels was higher during the antepartum (75.7%, 95% CI 71.5-79.7%) than during postpartum (53.0%, 95% CI 32.8-72.7%; P = 0.005). Selected reported barriers for nonadherence included physical, economic and emotional stresses, depression (especially postdelivery), alcohol or drug use, and ART dosing frequency or pill burden. CONCLUSION Our findings indicate that only 73.5% of pregnant women achieved optimal ART adherence. Reaching adequate ART adherence levels was a challenge in pregnancy, but especially during the postpartum period. Further research to investigate specific barriers and interventions to address them is urgently needed globally.

Abstract
Purpose. The purpose of this paper was to explore how loss to followup (LFTU) has affected the successful implementation of prevention of mother to child transmission of HIV-1 (PMTCT) programs in sub-Saharan Africa. Methods. We conducted an electronic search from the following databases PubMed, ScienceDirect, Directory of Open Access Journals (DOAJs), and PyscINFO. Additional searches were made in WHO, UNAIDS, UNICEF, Google, and Google scholar websites for (1) peer-reviewed published research, (2) scientific and technical reports, and (3) papers presented on scientific conferences. Results. A total of 678 articles, published from 1990 to 2011, were retrieved. Only 44 articles met our inclusion criteria and were included in the study. The rates of LTFU of mother-child pairs ranged from 19% to 89.4 in the reviewed articles. Health facility factors, fear of HIV-1 test, stigma and discrimination, home deliveries and socioeconomic factors were identified as reasons for LTFU. Conclusion. There is a great loss of mother-child pairs to follow up in PMTCT programs in sub-Saharan Africa. There is need for more research studies to develop public health models of care that can help to improve followup of mother-child pairs in PMTCT programs in Sub-Saharan Africa.

Abstract
INTRODUCTION Numerous barriers to optimal uptake of prevention of mother to child transmission (PMTCT) services occur at community level (i.e., outside the healthcare setting). To achieve elimination of paediatric HIV, therefore, interventions must also work within communities to address these barriers and increase service use and need to be informed by evidence. This paper reviews community-based approaches that have been used in resource-limited settings to increase rates of PMTCT enrolment, retention in care and successful treatment outcomes. It aims to identify which interventions work, why they may do so and what knowledge gaps remain. METHODS First, we identified barriers to PMTCT that originate outside the health system. These were used to construct a social ecological framework categorizing barriers to PMTCT into the following levels of influence: individual, peer and family, community and sociocultural. We then used this conceptual framework to guide a review of the literature on community-based approaches, defined as interventions delivered outside of formal health settings, with the goal of increasing uptake, retention, adherence and positive psychosocial outcomes in PMTCT programmes in resource-poor countries. RESULTS Our review found evidence of effectiveness of strategies targeting individuals and peer/family levels (e.g., providing household HIV testing and training peer counsellors to support exclusive breastfeeding) and at community level (e.g., participatory women's groups and home-based care to support adherence and retention). Evidence is more limited for complex interventions combining multiple strategies across different ecological levels. There is often little information describing implementation; and approaches such as "community mobilization" remain poorly defined. CONCLUSIONS Evidence from existing community approaches can be adapted for use in planning PMTCT. However, for successful replication of evidence-based interventions to occur, comprehensive process evaluations are needed to elucidate the pathways through which specific interventions achieve desired PMTCT outcomes. A social ecological framework can help analyze the complex interplay of facilitators and barriers to PMTCT service uptake in each context, thus helping to inform selection of locally relevant community-based interventions.

Abstract
BACKGROUND Operational effectiveness of large-scale national programmes for the prevention of mother to child transmission (PMTCT) of HIV in sub-Saharan Africa remains limited. We report on HIV-free survival among nine- to 24-month-old children born to HIV-positive mothers in the national PMTCT programme in Rwanda. METHODS We conducted a national representative household survey between February and May 2009. Participants were mothers who had attended antenatal care at least once during their most recent pregnancy, and whose children were aged nine to 24 months. A two-stage stratified (geographic location of PMTCT site, maternal HIV status during pregnancy) cluster sampling was used to select mother-infant pairs to be interviewed during household visits. Alive children born from HIV-positive mothers (HIV-exposed children) were tested for HIV according to routine HIV testing protocol. We calculated HIV-free survival at nine to 24 months. We subsequently determined factors associated with mother to child transmission of HIV, child death and HIV-free survival using logistic regression. RESULTS Out of 1448 HIV-exposed children surveyed, 44 (3.0%) were reported dead by nine months of age. Of the 1340 children alive, 53 (4.0%) tested HIV positive. HIV-free survival was estimated at 91.9% (95% confidence interval: 90.4-93.3%) at nine to 24 months. Adjusting for maternal, child and health system factors, being a member of an association of people living with HIV (adjusted odds ratio: 0.7, 95% CI: 0.1-0.995) improved by 30% HIV-free survival among children, whereas the maternal use of a highly active antiretroviral therapy (HAART) regimen for PMTCT (aOR: 0.6, 95% CI: 0.3-1.07) had a borderline effect. CONCLUSIONS HIV-free survival among HIV-exposed children aged nine to 24 months is estimated at 91.9% in Rwanda. The national PMTCT programme could achieve greater impact on child survival by ensuring access to HAART for all HIV-positive pregnant women in need, improving the quality of the programme in rural areas, and strengthening linkages with community-based support systems, including associations of people living with HIV.

Uptake of prevention of mother to child transmission interventions in Kenya: health systems are more influential than stigma. J Int AIDS Soc 2011; 14:61.

Abstract
Background We set out to determine the relative roles of stigma versus health systems in non-uptake of prevention of mother to child transmission (PMTCT) of HIV-1 interventions: we conducted cross-sectional assessment of all consenting mothers accompanying infants for six-week immunizations. Methods Between September 2008 and March 2009, mothers at six maternal and child health clinics in Kenya's Nairobi and Nyanza provinces were interviewed regarding PMTCT intervention uptake during recent pregnancy. Stigma was ascertained using a previously published standardized questionnaire and infant HIV-1 status determined by HIV-1 polymerase chain reaction. Results Among 2663 mothers, 2453 (92.1%) reported antenatal HIV-1 testing. Untested mothers were more likely to have less than secondary education (85.2% vs. 74.9%, p = 0.001), be from Nyanza (47.1% vs. 32.2%, p < 0.001) and have lower socio-economic status. Among 318 HIV-1-infected mothers, 90% reported use of maternal or infant antiretrovirals. Facility delivery was less common among HIV-1-infected mothers (69% vs. 76%, p = 0.009) and was associated with antiretroviral use (p < 0.001). Although internal or external stigma indicators were reported by between 12% and 59% of women, stigma was not associated with lower HIV-1 testing or infant HIV-1 infection rates; internal stigma was associated with modestly decreased antiretroviral uptake. Health system factors contributed to about 60% of non-testing among mothers who attended antenatal clinics and to missed opportunities in offering antiretrovirals and utilization of facility delivery. Eight percent of six-week-old HIV-1-exposed infants were HIV-1 infected. Conclusions Antenatal HIV-1 testing and antiretroviral uptake was high (both more than 90%) and infant HIV-1 infection risk was low, reflecting high PMTCT coverage. Investment in health systems to deliver HIV-1 testing and antiretrovirals can effectively prevent infant HIV-1 infection despite substantial HIV-1 stigma.

Abstract
Background Prevention of mother to child HIV transmission (PMTCT) programmes have great potential to achieve virtual elimination of perinatal HIV transmission provided that PMTCT recommendations are properly followed. This study assessed mothers and infants adherence to medication regimen for PMTCT and the proportions of exposed infants who were followed up in the PMTCT programme. Methods A prospective cohort study was conducted among 282 HIV-positive mothers attending 15 health facilities in Addis Ababa, Ethiopia. Descriptive statistics, bivariate and mulitivariate logistic regression analyses were done. Results Of 282 mothers enrolled in the cohort, 232 (82%, 95% CI 77-86%) initiated medication during pregnancy, 154 (64%) initiated combined zidovudine (ZDV) prophylaxis regimen while 78 (33%) were initiated lifelong antiretroviral treatment (ART). In total, 171 (60%, 95% CI 55-66%) mothers ingested medication during labour. Of the 221 live born infants (including two sets of twins), 191 (87%, 95% CI 81-90%) ingested ZDV and single-dose nevirapine (sdNVP) at birth. Of the 219 live births (twin births were counted once), 148 (68%, 95% CI 61-73%) mother-infant pairs ingested their medication at birth. Medication ingested by mother-infant pairs at birth was significantly and independently associated with place of delivery. Mother-infant pairs attended in health facilities at birth were more likely (OR 6.7 95% CI 2.90-21.65) to ingest their medication than those who were attended at home. Overall, 189 (86%, 95% CI 80-90%) infants were brought for first pentavalent vaccine and 115 (52%, 95% CI 45-58%) for early infant diagnosis at six-weeks postpartum. Among the infants brought for early diagnosis, 71 (32%, 95% CI 26-39%) had documented HIV test results and six (8.4%) were HIV positive. Conclusions We found a progressive decline in medication adherence across the perinatal period. There is a big gap between mediation initiated during pregnancy and actually ingested by the mother-infant pairs at birth. Follow up for HIV-exposed infants seem not to be organized and is inconsistent. In order to maximize effectiveness of the PMTCT programme, the rate of institutional delivery should be increased, the quality of obstetric services should be improved and missed opportunities to exposed infant follow up should be minimized.

Abstract
BACKGROUND Women living with HIV in sub-Saharan Africa face significant challenges in accessing HIV care and adhering to antiretroviral therapy. Most reports have focused on issues relating to long-term adherence such as those surrounding stigma and disclosure, hunger, cultural factors, lack of accurate health information, lack of social support, medication side effects and overcrowded health systems. Information related to the challenges facing pregnant women when taking antiretrovirals for prophylactic purposes is limited. The "Kesho Bora Study" is a multicentre prevention of mother-to-child transmission (PMTCT) trial in sub-Saharan Africa evaluating the PMTCT efficacy of triple therapy until cessation of breast feeding compared to short course zidovudine monotherapy in a predominantly breast feeding population. Following unexplained discrepancies during objective adherence assessments, a sub-study was conducted at one site to examine the underlying adherence issues. METHODS The counselling and clinical notes of all 100 enrolled Zulu women were examined. Extracted information was supplemented by unstructured, free-ranging interviews conducted by trained adherence counsellors on 43 consecutive women attending the trial clinic over a two-week period. Adherence was defined as good (>95% adherence), or poor (<95% adherence). RESULTS Reasons provided for sub-optimal adherence included therapy misconceptions/misunderstandings, antiretroviral use by relatives, domestic violence, poverty and issues relating to disclosure and stigma. About 61% (57/94) of antenatal women had good adherence with their PMTCT prophylaxis, with no significant difference shown between those taking the long and short course. CONCLUSION Antenatal women in northern rural KwaZulu-Natal face significant challenges in taking antiretroviral PMTCT prophylaxis.

Abstract
We assess the coverage of a Prevention of Mother-to-child Transmission (PMTCT) programme in Busia (Kenya) from 1 January 2006 to 31 December 2008 and estimate the risk of transmission of HIV. We also estimate the odds of HIV transmission according to pharmacological intervention received. Programme coverage was estimated as the proportion of mother-baby pairs receiving any antiretroviral (ARV) regimen among all HIV-positive women attending services. We estimated the mother-to-child transmission (MTCT) rate and their 95% confidence interval (95%CI) using the direct method of calculation (intermediate estimate). A case-control study was established among all children born to HIV-positive mothers with information on outcome (HIV status of the babies) and exposure (data on pharmacological intervention). Cases were all HIV-positive children and controls were the HIV-negative ones. Exposure was defined as: (1) complete protocol: ARV prescribed according World Health Organisation recommendations; (2) partial protocol: does not meet criteria for complete protocol; and (3) no intervention: ARVs were not prescribed to both mother and child. Babies were tested using DNA Polymerase Chain Reaction at six weeks of life and six weeks after breastfeeding ceased. In the study period, 22,566 women accepted testing, 1668 were HIV positive (7.4%; 95%CI 7.05-7.73); 1036 (62%) registered in the programme and 632 were lost. Programme coverage was 40.4% (95%CI 37.9-42.7). Out of the 767 newborns, 28 (3.6%) died, 148 (19.3%) defaulted, 282 (36.7%) were administratively censored and 309 (40.2%) babies completed the follow-up as per protocol; 49 were HIV positive and MTCT risk was 15.86% (95%CI 11.6-20.1). The odds of having an HIV-positive baby was 4.6 times higher among pairs receiving a partial protocol compared to those receiving a complete protocol and 43 times higher among those receiving no intervention. Our data show a good level of enrolment but low global coverage rate. It demonstrates that ARV regimens can be implemented in low resource rural settings with marked decreases of MTCT. Increasing the coverage of PMTCT programmes remains the main challenge.

Abstract
SUMMARY OBJECTIVES To determine factors associated with pregnant women being HIV positive, barriers to the uptake of single-dose nevirapine (sdNVP) for prevention of mother-to-child transmission (PMTCT) and feasibility and effectiveness of reporting HIV-exposed infants born in facilities with no PMTCT services so as to receive NVP. METHODS From 2002 to 2007, a sdNVP PMTCT service was implemented in 53 rural villages of south-west Uganda. Twenty-five of them were HIV-surveillance study villages. The proportions of mothers testing positive and mother and newborns receiving and ingesting sdNVP and associated factors were determined. RESULTS Women with incomplete primary or no education, aged 25-34 years or not living with their partners were at increased risk of being HIV infected. Seventy-seven percentage of pregnant women with HIV (PWH) received therapy. Of the 63 PWH who received therapy and had surviving live births, only 39 (62%) reported births and received newborn prophylaxis within 72 h. Women were more likely to collect and ingest NVP if they were from study villages, preferred home administration of newborn NVP or presented at a more advanced stage of pregnancy. Newborns were more likely to be reported and receive NVP if mothers were aged 25-34 years, on antiretroviral therapy (ART) or came from study villages. CONCLUSIONS The uptake of PMTCT services was unacceptably low. Asking PWH with less advanced pregnancies to return to collect NVP leads to missed opportunities especially if PWH are less educated. Birth reporting enabled the programme to provide NVP to some infants who otherwise would have missed. Antenatal, delivery and PMTCT services should be integrated.

Prevention of mother-to-child transmission of HIV infection: views and perceptions about swallowing nevirapine in rural Lilongwe, Malawi. BMC Public Health 2010; 10:354. [PMID: 20565930 PMCID: PMC2910675 DOI: 10.1186/1471-2458-10-354] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2009] [Accepted: 06/21/2010] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In 2006 the World Health Organization described the status of prevention of mother to child transmission (PMTCT) service implementation as unacceptable, with an urgent need for a renewed public health approach to improve access. For PMTCT to be effective it needs to be accessible, acceptable and affordable; however research in Africa into accessibility, uptake and acceptability of PMTCT services has been predominately urban based and usually focusing on women who deliver in hospitals. The importance of involving other community members to strengthen both PMTCT uptake and adherence, and to support women emotionally, has been advocated. Urban men's and rural traditional birth attendants' (TBAs) involvement have improved uptake of HIV testing and of nevirapine. METHODS A qualitative study was carried out in a rural district of Malawi's central region to explore the views about and perceptions of PMTCT antiretroviral treatment. Semi-structured interviews and focus group discussions were held with antenatal and postnatal women, fathers, grandmothers, TBAs, community leaders and PMTCT health workers. RESULTS Two broad themes of findings emerged: those that relate to the hospital PMTCT service, and those that relate to the community. Trust in the hospital was strong, but distance, transport costs and perceived harsh, threatening health worker attitudes were barriers to access. Grandmothers were perceived to have influence on the management of labour, unlike fathers, but both were suggested as key people to ensure that babies are brought to the hospital for nevirapine syrup. TBAs were seen as powerful, local, and important community members, but some as uneducated. CONCLUSION PMTCT was seen as a community issue in which more than the mother alone can be involved. To support access to PMTCT, especially for rural women, there is need for further innovation and implementation research on involving TBAs in some aspects of PMTCT services, and in negotiating with women which community members, if any, they would like to support them in ensuring that newborn babies receive nevirapine.

Abstract
AIM To identify factors that influence adherence to antiretroviral (ARV) prophylaxis by HIV positive mothers participating in the HIV prevention of mother to child (PMTCT) programme. METHODS Post-delivery 815 HIV-infected mothers aged 18 years and above with babies aged 3-6 months were interviewed in Gert Sibande District, Mpumalanga province, South Africa. RESULTS Eighty five percent of the mothers indicated that they had been provided with nevirapine and 78.4% took it before or at the onset of labour and infant nevirapine intake was 76.9%. In multivariate analysis it was found that women with better PMTCT knowledge had a higher perceived confidentiality about HIV status at the health facility. They had a term delivery and those who had told their partner about nevirapine had a higher maternal nevirapine adherence. Women who had also told their partner about nevirapine, whose partner was asked for an HIV test and those who knew the HIV status of their infant had higher infant nevirapine adherence. CONCLUSION Adherence to maternal and infant ARV prophylaxis was found to be sub-optimal. Health services delivery factors, male involvement, communication and social support contribute to adherence to ARV prophylaxis in this largely rural setting in South Africa.

Non-adherence to the single dose nevirapine regimen for the prevention of mother-to-child transmission of HIV in Bindura town, Zimbabwe: a cross-sectional analytic study. BMC Public Health 2010; 10:218. [PMID: 20426830 PMCID: PMC2873585 DOI: 10.1186/1471-2458-10-218] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2009] [Accepted: 04/28/2010] [Indexed: 11/18/2022] Open
Abstract
Background The Prevention of Mother to Child Transmission of HIV (PMTCT) programme was introduced at Bindura Hospital in 2003. Seven additional satellite PMTCT clinics were set up in the district to increase service coverage but uptake of PMTCT interventions remained unsatisfactory. In this study we determined the prevalence of and factors associated with non-adherence to the single dose nevirapine (SD-NVP) regimen for PMTCT in Bindura town. Methods An analytic cross-sectional study was conducted in four health institutions in Bindura town. Participants were mother-baby pairs on the PMTCT programme attending routine six weeks post natal visits in the participating health institutions from March to July 2008. We interviewed 212 mothers using a structured questionnaire. Results The non-adherence rate to the maternal nevirapine dose was 30.7%, while non-adherence to the newborn nevirapine dose was 26.9%. The combined mother-baby pair nevirapine non-adherence was 42.9%. Non-adherence to the maternal dose of nevirapine was associated with lack of maternal secondary education (POR = 2.38; 95%CI: 1.05-3.39) and multi-parity (POR = 2.66; 95%CI: 1.05-6.72), while previous maternal exposure to the PMTCT programme (POR = 0.22; 95%CI: 0.08-0.57) and giving the mother a NVP tablet to take home during antenatal care (POR = 0.03; 95%CI: 0.01-0.09) were associated with improved maternal adherence to nevirapine. Non-adherence to the infant dose of nevirapine was associated with maternal non-disclosure of HIV results to sexual partner (POR = 2.75; 95%CI: 1.04-7.32) and home deliveries (POR = 48.76; 95%CI: 17.51-135.82). Conclusions Non-adherence to nevirapine prophylaxis for PMTCT was high in Bindura. Ensuring institutional deliveries, encouraging self-disclosure of HIV results by the mothers to their partners and giving HIV positive mothers nevirapine doses to take home early in pregnancy all play significant roles in improving adherence to PMTCT prophylaxis.

Abstract
Background With the accessibility of prevention of mother to child transmission (PMTCT) services in sub-Saharan Africa, more women are being tested for HIV in antenatal care settings. Involving partners in the counselling and testing process could help prevent horizontal and vertical transmission of HIV. This study was conducted to assess the feasibility of couples' voluntary counseling and testing (CVCT) in antenatal care and to measure compliance with PMTCT. Methods A prospective cohort study was conducted over eight months at two public antenatal clinics in Kigali, Rwanda, and Lusaka, Zambia. A convenience sample of 3625 pregnant women was enrolled. Of these, 1054 women were lost to follow up. The intervention consisted of same-day individual voluntary counselling and testing (VCT) and weekend CVCT; HIV-positive participants received nevirapine tablets. In Kigali, nevirapine syrup was provided in the labour and delivery ward; in Lusaka, nevirapine syrup was supplied in pre-measured single-dose syringes. The main outcome measures were nurse midwife-recorded deliveries and reported nevirapine use. Results In eight months, 1940 women enrolled in Kigali (984 VCT, 956 CVCT) and 1685 women enrolled in Lusaka (1022 VCT, 663 CVCT). HIV prevalence was 14% in Kigali, and 27% in Lusaka. Loss to follow up was more common in Kigali than Lusaka (33% vs. 24%, p = 0.000). In Lusaka, HIV-positive and HIV-negative women had significantly different loss-to-follow-up rates (30% vs. 22%, p = 0.002). CVCT was associated with reduced loss to follow up: in Kigali, 31% of couples versus 36% of women testing alone (p = 0.011); and in Lusaka, 22% of couples versus 25% of women testing alone (p = 0.137). Among HIV-positive women with follow up, CVCT had no impact on nevirapine use (86-89% in Kigali; 78-79% in Lusaka). Conclusions Weekend CVCT, though new, was feasible in both capital cities. The beneficial impact of CVCT on loss to follow up was significant, while nevirapine compliance was similar in women tested alone or with their partners. Pre-measured nevirapine syrup syringes provided flexibility to HIV-positive mothers in Lusaka, but may have contributed to study loss to follow up. These two prevention interventions remain a challenge, with CVCT still operating without supportive government policy in Zambia.

Abstract
Scale-up of vertical HIV transmission prevention has been too slow in sub-Saharan Africa. We describe approaches, challenges, and results obtained in Kinshasa. Staff members of 21 clinics managed by public servants or non-governmental organizations were trained in improved basic antenatal care (ANC) including nevirapine (NVP)-based HIV transmission prevention. Program initiation was supported on-site logistically and technically. Aggregate implementation data were collected and used for program monitoring. Contextual information was obtained through a survey. Among 45,262 women seeking ANC from June 2003 through July 2005, 90% accepted testing; 792 (1.9%) had HIV of whom 599 (76%) returned for their result. Among 414 HIV+ women who delivered in participating maternities, NVP coverage was 79%; 92% of newborns received NVP. Differences were noted by clinic management in program implementation and HIV prevalence (1.2 to 3.0%). Initiating vertical HIV transmission prevention embedded in improved antenatal services in a fragile, fragmented, severely resource-deprived health care system was possible and improved over time. Scope and quality of service coverage should further increase; strategies to decrease loss to follow-up of HIV+ women should be identified to improve program effectiveness. The observed differences in HIV prevalence highlight the importance of selecting representative sentinel surveillance centers.

Abstract
OBJECTIVES Single-dose nevirapine (SDNVP) for prevention of mother-to-child HIV transmission selects mutations conferring resistance to nonnucleoside reverse transcriptase inhibitor (NNRTI)-based therapy. We investigated mortality and virologic and clinical outcomes after introduction of antiretroviral treatment (ART) among a cohort of women given SDNVP. METHODS When ART programs were introduced in 2004 in Lusaka, Zambia, we were completing a trial of infant feeding, which involved following HIV-infected women who received SDNVP between 2001 and 2005. Women still in follow-up or who could be contacted were evaluated for eligibility for ART (CD4 count <200 or <350 and World Health Organization stage >or=3) and started on NNRTI-based therapy if eligible. We compared mortality in the cohort of women before and after ART access, and examined, among women initiating ART, whether virologic response was better allowing a longer time to elapse between SDNVP and treatment initiation. RESULTS In the cohort of 872 women, mortality more than halved after ART became available (relative hazard = 0.46, 95% confidence interval: 0.23 to 0.91, P = 0.03). Of 161 SDNVP-exposed women followed on NNRTI-based ART, 70.8% suppressed (viral load <400 copies/mL). Only 3 of 8 SDNVP-exposed women (37.5%) <6 months of starting therapy suppressed compared with 13 of 22 (59.1%) who started 6-12 months, 44 of 61 (72.1%) 12-24 months, and 54 of 70 (77.1%) >24 months after exposure (chi2 trend P = 0.01). CONCLUSIONS Most SDNVP-exposed women respond well to NNRTI-based therapy, but there was an attenuation of therapy efficacy that persisted to 12 months after exposure. Women should be screened for ART eligibility during pregnancy and started on effective regimens before delivery.

Abstract
BACKGROUND Safety and effectiveness of efficacious antiretroviral (ARV) regimens beyond single-dose nevirapine (sdNVP) for prevention of mother-to-child transmission (PMTCT) have been demonstrated in well-controlled clinical studies or in secondary- and tertiary-level facilities in developing countries. This paper reports on implementation of and factors associated with efficacious ARV regimens among HIV-positive pregnant women attending antenatal clinics in primary health centers (PHCs) in Zambia. METHODS Blood sample taken for CD4 cell count, availability of CD4 count results, type of ARV prophylaxis for mothers, and additional PMTCT service data were collected for HIV-positive pregnant women and newborns who attended 60 PHCs between April 2007 and March 2008. RESULTS Of 14,815 HIV-positive pregnant women registered in the 60 PHCs, 2,528 (17.1%) had their CD4 cells counted; of those, 1,680 (66.5%) had CD4 count results available at PHCs; of those, 796 (47.4%) had CD4 count<or=350 cells/mm3 and thus were eligible for combination antiretroviral treatment (cART); and of those, 581 (73.0%) were initiated on cART. The proportion of HIV-positive pregnant women whose blood sample was collected for CD4 cell count was positively associated with (1) blood-draw for CD4 count occurring on the same day as determination of HIV-positive status; (2) CD4 results sent back to the health facilities within seven days; (3) facilities without providers trained to offer ART; and (4) urban location of PHC. Initiation of cART among HIV-positive pregnant women was associated with the PHC's capacity to provide care and antiretroviral treatment services. Overall, of the 14,815 HIV-positive pregnant women registered, 10,015 were initiated on any type of ARV regimen: 581 on cART, 3,041 on short course double ARV regimen, and 6,393 on sdNVP. CONCLUSION Efficacious ARV regimens beyond sdNVP can be implemented in resource-constrained PHCs. The majority (73.0%) of women identified eligible for ART were initiated on cART; however, a minority (11.3%) of HIV-positive pregnant women were assessed for CD4 count and had their test results available. Factors associated with implementation of more efficacious ARV regimens include timing of blood-draw for CD4 count and capacity to initiate cART onsite where PMTCT services were being offered.

Abstract
BACKGROUND The effect of breastfeeding on growth in HIV-exposed infants is not well described. OBJECTIVE The objective was to evaluate the effect of early breastfeeding cessation on growth. DESIGN In a trial conducted in Lusaka, Zambia, HIV-infected mothers were randomly assigned to exclusive breastfeeding for 4 mo followed by rapid weaning to replacement foods or exclusive breastfeeding for 6 mo followed by introduction of complementary foods and continued breastfeeding for a duration of the mother's choice. Weight-for-age z score (WAZ), length-for-age z score (LAZ), and weight-for-length z score (WLZ) and the self-reported breastfeeding practices of 593 HIV-uninfected singletons were analyzed. Generalized estimating equations were used to adjust for confounders. RESULTS WAZ scores declined precipitously between 4.5 and 15 mo. The decline was slower in the breastfed infants. At 9, 12, and 15 mo, mean WAZs were, respectively, -0.74, -0.92, and -1.06 in infants who were reportedly breastfed and were -1.07, -1.20, and -1.31 in the weaned infants (P = 0.003, 0.007, and 0.02, respectively). No differences were observed past 15 mo. Breastfeeding practice was not associated with LAZ, which declined from -0.98 to -2.24 from 1 to 24 mo. After adjustment for birth weight, maternal viral load, body mass index, education, season, and marital and socioeconomic status, not breastfeeding was associated with a 0.28 decline in WAZ between 4.5 and 15 mo (P < 0.0001). During the rainy season, not breastfeeding was associated with a larger WAZ decline (0.33) than during the dry season (0.22; P for interaction = 0.02). CONCLUSIONS Early growth is compromised in uninfected children born to HIV-infected Zambian mothers. Continued breastfeeding partially mitigates this effect through 15 mo. Nutritional interventions to complement breastfeeding after 6 mo are urgently needed. This trial was registered at clinicaltrials.gov as NCT00310726.

Abstract
Despite technical means and apparent political will, the percentage of pregnant women involved in preventing mother-to-child transmission (PMTCT) interventions is not increasing as fast as public health authorities would expect. This is even more striking when compared to the scaling up of access to antiretroviral treatment. It seems important to analyze the successes and failures of the programs and the "scaling-up" of PMTCT programs. This is a major issue for women at two levels: women are very concerned about the health of their children, and they are the ones who implement prevention in collaboration with health services. A review of achievements and failures described from a public health perspective may lead to greater understanding of the social aspects involved in PMTCT program achievements and failures. This paper is based on the combination of a literature review and empirical evidence collected during 15 years of PMTCT implementation, childcare research and treatment programs in West Africa. The analysis aims to identify the social issues that explain the gap between PMTCT program aims and achievements in order to encourage research in the social sciences regarding relationships between mothers and the care system. We find it is possible to build programs at the national level that have a high degree of acceptance of testing and intervention, with a progressive decline in HIV infection among children. However, many obstacles remain, highlighting the necessity to broaden access to HIV screening, develop mass campaigns on testing for couples and improve HIV care and training for caregivers. Because HIV-infected pregnant women are experiencing great psychological distress, healthcare providers must use an approach that is as friendly as possible.

Abstract
OBJECTIVE To assess the impact of prior exposure to single-dose nevirapine (sdNVP) on mother-to-child transmission and genotypic resistance in HIV-infected women. DESIGN Prospective study of 120 women exposed to the HIVNET 012 sdNVP regimen in two successive pregnancies and 240 antiretroviral (ARV)-naïve, multiparous women who received sdNVP for the first time. RESULTS One hundred and eight of 120 and 193 of 240 women returned for a postpartum visit by 6 weeks. HIV-1 was detected in 11.1% (95% confidence interval = 5.9-18.6) of the infants of women previously exposed to sdNVP and 4.2% (95% confidence interval = 1.3-7.0) of those exposed for the first time (P = 0.028). Rates of maternal HIV-1 genotypic resistance at 6 weeks postdelivery were 37.5% and 46.4%, respectively (P = 0.119). Sensitive mutation-specific real-time PCR testing found three of 12 previously exposed women who transmitted HIV-1 to their infants had either K103N or Y181C at baseline compared with one of eight ARV-naïve, transmitting women who had Y181C. None of 40 randomly selected nontransmitting women from either group had detectable NVP resistance mutations prior to sdNVP exposure. CONCLUSION This study shows that effectiveness of sdNVP may be compromised by prior exposure to sdNVP, although the increase in transmission rate after prior exposure could not be explained by the detection of NVP resistance mutations prior to re-exposure as measured both by standard genotyping and highly sensitive allele-specific PCR assays. Furthermore, transmission rates of women with prior exposure were not higher than those reported elsewhere.

Abstract
Studies investigating the predictors of growth in infants born to HIV-infected women in developing countries are limited. Using data from 886 Tanzanian HIV-infected women and their infants, we examined the impact of maternal socioeconomic and immunological status, infant characteristics at birth, and HIV, diarrhea and respiratory infections on infants' monthly length-for-age (LAZ) and length-for-weight (WLZ) z-scores during the first 2 years of life. We used restricted cubic splines to estimate average adjusted growth curves by categories of each predictor. LAZ decreased significantly during the first 2 years. WLZ increased from birth to 4 months but decreased significantly thereafter. Greater maternal schooling significantly reduced deterioration in LAZ and WLZ scores from birth to 24 months, while maternal CD4 cell counts >or=200 mm(-3) at baseline were associated with reduced deterioration in LAZ scores. Infants born pre-term or with low-birth weight were significantly more stunted and wasted than their reference groups at all time points though their rate of growth faltering was slower. Infant-HIV status was strongly associated with significantly greater deterioration in LAZ and WLZ scores, beginning at about 4 months of age. Episodes of diarrhea or respiratory infections were related to significantly lower WLZ but not LAZ scores, independent of infant-HIV status. In conclusion, maternal schooling, immunological status and infant infections are important predictors of early growth in children born to HIV-positive women.

Abstract
The aim of this study was to investigate the implementation of a prevention of mother-to-child transmission (PMTCT) program and to evaluate the uptake and adherence to single-dose nevirapine in a cohort sample that had undergone PMTCT in five public clinics in a resource-poor setting, Quakeni Local Service Area, O.R. Tambo District in the Eastern Cape, South Africa. Results indicated that 116 women (15.3% of the sample) were infected with HIV, 642 (84.7%) were uninfected, and 552 (42.1%) had an unknown HIV status. Almost all of the women had received information about HIV and HIV testing prenatally, but 552 (42%) had not been tested for HIV, and their HIV status was unknown. Only 66 (57%) of the HIV-infected pregnant women had been provided with nevirapine. It is recommended that the quality of HIV counseling be improved and the program of maternal self-medication with nevirapine tablets at onset of labor and maternal provision of nevirapine syrup to newborns be encouraged.

Abstract
OBJECTIVES To describe experiences, and identify factors associated with nonadherence to a single-dose nevirapine (SD-NVP) regimen for the prevention of mother-to-child transmission (PMTCT) of HIV in Rwanda. METHODS In April to May 2006, using a case-control design at 12 PMTCT sites, we interviewed HIV-infected women who did not adhere (n = 111) and who adhered (n = 125) to the PMTCT prophylaxis regimen. Nonadherence was defined as mother and/or infant not ingesting SD-NVP at the recommended time or not at all and adherence as mother-infant pairs who ingested it as recommended. RESULTS Only 61% of nonadherent women had received SD-NVP during pregnancy or delivery. Among nonadherent women who received SD-NVP, 80% ingested it at the recommended time, representing 49% of all nonadherent women. Only 7% of their newborns ingested SD-NVP. Multivariate logistic regression showed that unmarried women, less educated women, women who made 2 or less antenatal care visits, and those offered HIV testing after their first antenatal care visit were more likely to be nonadherent to PMTCT prophylaxis. Not disclosing one's HIV status to someone aside from a partner was also associated with nonadherence in mother-infant pairs. CONCLUSIONS Sociodemographic factors, health services delivery factors, and a lack of communication and social support contributed to nonadherence to PMTCT prophylaxis in Rwanda.

Participation of traditional birth attendants in prevention of mother-to-child transmission of HIV services in two rural districts in Zimbabwe: a feasibility study. BMC Public Health 2008; 8:401. [PMID: 19061506 PMCID: PMC2612666 DOI: 10.1186/1471-2458-8-401] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2008] [Accepted: 12/05/2008] [Indexed: 11/23/2022] Open
Abstract
Background Prevention of Mother-to-Child Transmission of HIV (PMTCT) is among the key HIV prevention strategies in Zimbabwe. A decrease in use of antenatal care (ANC) services with an increase in home deliveries is affecting the coverage of PMTCT interventions in a context of accelerated economic crisis. The main objective was to evaluate acceptability and feasibility of reinforcing the role of traditional birth attendants (TBAs) in family and child health services through their participation in PMTCT programmes in Zimbabwe. Methods A community based cross-sectional survey was undertaken using multistage cluster sampling in two rural districts through interviews and focus group discussions among women who delivered at home with a TBA, those who had an institutional delivery and TBAs. Results 45% of TBAs interviewed knew the principles of PMTCT and 8% delivered a woman with known HIV-positive status in previous year. Of the complete package of PMTCT services, more than 75% of TBAs agreed to participate in most activities with the exception of performing a blood test (17%), accompanying new-borns to closest health centre to receive medication (15%) and assisting health centres in documentation of the link ANC-PMTCT services (18%). Women who delivered at home were less likely to have received more than one ANC service or have had contact with a health centre compared to women who delivered in a health centre (91.0% vs 72.6%; P < 0.001). Also, 63.6% of the women who delivered in a health centre had the opportunity to choose the place of delivery compared to 39.4% of women who delivered at home (P < 0.001). More than 85% of women agreed that TBAs could participate in all activities related to a PMTCT programme with the exception of performing a blood test for HIV. Concerns were highlighted regarding confidentiality of the HIV-serostatus of women. Conclusion Although the long-term goal of ANC service delivery in Zimbabwe remains the provision of skilled delivery attendance, PMTCT programmes will benefit from complementary approaches to prevent missed opportunities. TBAs are willing to expand their scope of work regarding activities related to PMTCT. There is a need to reinforce their knowledge on MTCT prevention measures and better integrate them into the health system.
