Understanding the uptake and determinants of prevention of mother-to-child transmission of HIV services in East Africa: Mixed methods systematic review and meta-analysis. PLoS One 2024; 19:e0300606. [PMID: 38635647 PMCID: PMC11025786 DOI: 10.1371/journal.pone.0300606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 02/28/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND Prevention of mother-to-child transmission (PMTCT) of HIV service is conceptualized as a series of cascades that begins with all pregnant women and ends with the detection of a final HIV status in HIV-exposed infants (HEIs). A low rate of cascade completion by mothers' results in an increased risk of HIV transmission to their infants. Therefore, this review aimed to understand the uptake and determinants of key PMTCT services cascades in East Africa. METHODS We searched CINAHL, EMBASE, MEDLINE, Scopus, and AIM databases using a predetermined search strategy to identify studies published from January 2012 through to March 2022 on the uptake and determinants of PMTCT of HIV services. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. A random-effects model was used to obtain pooled estimates of (i) maternal HIV testing (ii) maternal ART initiation, (iii) infant ARV prophylaxis and (iv) early infant diagnosis (EID). Factors from quantitative studies were reviewed using a coding template based on the domains of the Andersen model (i.e., environmental, predisposing, enabling and need factors) and qualitative studies were reviewed using a thematic synthesis approach. RESULTS The searches yielded 2231 articles and we systematically reduced to 52 included studies. Forty quantitative, eight qualitative, and four mixed methods papers were located containing evidence on the uptake and determinants of PMTCT services. The pooled proportions of maternal HIV test and ART uptake in East Africa were 82.6% (95% CI: 75.6-88.0%) and 88.3% (95% CI: 78.5-93.9%). Similarly, the pooled estimates of infant ARV prophylaxis and EID uptake were 84.9% (95% CI: 80.7-88.3%) and 68.7% (95% CI: 57.6-78.0) respectively. Key factors identified were the place of residence, stigma, the age of women, the educational status of both parents, marital status, socioeconomic status, Knowledge about HIV/PMTCT, access to healthcare facilities, attitudes/perceived benefits towards PMTCT services, prior use of maternal and child health (MCH) services, and healthcare-related factors like resource scarcity and insufficient follow-up supervision. CONCLUSION Most of the identified factors were modifiable and should be considered when formulating policies and planning interventions. Hence, promoting women's education and economic empowerment, strengthening staff supervision, improving access to and integration with MCH services, and actively involving the community to reduce stigma are suggested. Engaging community health workers and expert mothers can also help to share the workload of healthcare providers because of the human resource shortage.

Abstract
BACKGROUND Mother-To-Child-Transmission (MTCT) of Human Immunodeficiency Virus (HIV) occurs during pregnancy, delivery and breastfeeding, and cause infection among several new-borns. However, there is limited recent evidence on the burden of MTCT of HIV in Ethiopia from a large-scale data. Thus, this study aimed to determine the positivity rate, trend and associated risk factors of MTCT among HIV-exposed infants. METHODOLOGY A cross-sectional study was conducted among 5,679 infants whose specimen referred to Ethiopian Public Health Institute HIV referral laboratory for Early Infant Diagnosis (EID) from January 01, 2016, to December 31, 2020. Data were extracted from the national EID database. Frequencies and percentages were used to summarize the data on characteristics of infants. Logistic regression analysis was employed to identify factors associated with positivity rate of MTCT of HIV. Level of significance was set at 5%. RESULTS The mean age of the infants was 12.6 (± 14.6) weeks with an age range of 4 to 72 weeks. Half of the infants (51.4%) were female. The positivity rate of MTCT decreased from 2.9% in 2016 to 0.9% in 2020 with five-year average positivity rate of 2.6%. HIV test after six weeks (Adjusted odds ratio (AOR) = 2.7; 95% confidence interval (CI): (1.8-4.0,)); p < 0.001), absence of prevention of mother-to-child-transmission (PMTCT) service (AOR = 4.6; 95% CI: (2.9-7.4)); p = 0.001), nevirapine prophylaxis not received (AOR = 2.0; 95% CI: (1.3-3.2)); p < 0.001), and unknown ART status of the mother at delivery (AOR = 11; 95% CI: (5.5-22.1)); p < 0.001) were significantly associated with MTCT of HIV. CONCLUSION The positivity rate of MTCT of HIV was showing declining tendency gradually in the study period. Strengthening PMTCT service, early HIV screening and starting ART for pregnant women, and early infant diagnosis are required to reduce the burden of HIV infection among infants exposed to HIV.

Abstract
OBJECTIVES Uganda adapted its policy for prevention of vertical transmission (VT) of HIV transmission as the World Health Organization released Options A, B and B+. We assessed trends in diagnostic testing, breastfeeding practices, maternal and infant antiretroviral therapy (ART), mortality, VT and HIV-free survival (HFS) among Ugandan infants born to women living with HIV during this period of successive guideline changes. METHODS This is is a retrospective observational study of infants attending early infant diagnosis clinics at two Ugandan hospitals. RESULTS A total of 1885 infants (48% female) were managed from 2009 to 2017. DNA polymerase chain reaction (PCR) for early infant diagnosis was performed on 1719 infants (92%, one or more PCR tests) and 676 infants (36%, two PCR tests). HIV serology was performed on 90 infants (4.8%). Testing increased over the study period but remained suboptimal, due to high loss to follow-up (LTFU). A total of 93% of infants were breastfed, for a median of 9.5 months. The duration of breast milk exposure increased over the study period, consistent with guidelines that increasingly encouraged breastfeeding. Nine cases (0.48%) of suspected breast milk transmission were observed. The use of ART increased significantly over the study period. Mortality (3.5%, 2.7% and 1.1%; p = 0.0076) and VT (17%, 12% and 7.4%; p < 0.0001) decreased over the study period (2008-2010, 2011-2012 and 2013-2017, respectively). LTFU values were 31%, 49% and 59% at 6, 12 and 18 months of age, respectively, with only modest improvements over time. HFS could only be conclusively documented in 532 infants (28%) because of LTFU. CONCLUSIONS From 2009 to 2017, outcomes improved among HIV-exposed infants in Uganda. LTFU remains a barrier to optimal care.

Abstract
BACKGROUND Early infant diagnosis (EID) of HIV, followed by effective care including antiretroviral therapy (ART), reduces infant mortality by 76% and HIV progression by 75%. In 2015, 50% of 1.2 million HIV-exposed infants (HEI) in 21 priority countries received a virologic test within the recommended 2 months of birth. We sought to identify factors associated with timely uptake of virologic EID among HEI and gain insight into missed opportunities. METHODS This was a cross-sectional study that used de-identified data from electronic medical records of 54 health facilities within the Christian Health Association of Kenya (CHAK) HIV Project database. All HEI who had their first HIV virologic test done between January 2015 and December 2017 were included in the study and categorized as either having the test within or after 8 weeks of birth. Multivariate linear mixed effects regression model was used to determine factors associated with uptake of the first HIV EID polymerase chain reaction (PCR). Predictor variables studied include sex, birth weight, the entry point into care, provision of ART prophylaxis for the infant, maternal ART at time of EID, mode of delivery, and place of delivery. RESULTS We included 2020 HEI of whom 1018 (50.4%) were female. A majority, 1596 (79.0%) had their first HIV PCR within 2 months of birth at a median age of 6.4 weeks (interquartile range 6-7.4). Overall, HIV positivity rate at initial test among this cohort was 1.2%. Delayed HIV PCR testing for EID was more likely to yield a positive result [adjusted odds ratio (aOR) = 1.29 (95% confidence interval (CI) 1.09-1.52) p = 0.003]. Infants of mothers not on ART at the time of HIV PCR test and infants who had not received prophylaxis to prevent vertical HIV transmission had significant increased odds of a delayed initial test [aOR = 1.27 (95% CI = 1.18-1.37) p = < 0.0001] and [aOR = 1.43 (95% CI 1.27-1.61) p = < 0.001] respectively. CONCLUSION An initial HIV PCR test done after 8 weeks of birth is likely to yield a positive result. Barriers to accessing ART for treatment among HIV-infected pregnant and breastfeeding women, and prophylaxis for the HEI were associated with delayed EID. In order to ensure timely EID, programs need to incorporate both facility and community strategy interventions to ensure all pregnant women seek antenatal care and deliver within health facilities.

Abstract
Background: Prevention of mother-to-child transmission of HIV program (PMTCT) is a comprehensive approach that aimed for the wellbeing of all HIV-infected women, to prevent new HIV infection among infants born to HIV-positive mothers, and providing management for HIV-positive women and infants. Nevertheless, there was considerably high attrition within the prevention of mother-to-child transmission programs that was merely because of loss to follow-up (LTFU) followed by mortality. In resource-limited countries, one-third of infected children die before 1 year, and more than half of them die before 2 years. The aim of this study was to assess the prevalence or incidence of mortality and LTFU among infants born from HIV-positive mothers in the Amhara regional state referral hospitals, Ethiopia. Methods: This study was conducted in five Amhara regional state referral hospitals' prevention of mother-to-child transmission departments. A simple random sampling technique with proportional allocation was used to assess the outcomes of 221 exposed infants. A retrospective cohort design was used in selecting the 221 exposed infants' document from the referral hospitals of the region, Amhara. The exposed infants' profiles were documented between January 1, 2014 and May 30, 2017. Results: This study described attritions (death and loss-to-follow-up) of exposed babies in PMTCT departments of Amhara regional state referral hospitals in Ethiopia. In this study, low LTFU with zero death was reported. Residence, immunization status of babies, and place of delivery were independent factors of LTFU. Conclusions: The cumulative incidence of mortality in this study was zero. This assured that the recommended option is substantial for the elimination of HIV-caused death in 2030 as per WHO plan. However, the cumulative incidence of LTFU was not zero.

Abstract
BACKGROUND Elimination of mother-to-child transmission of human immunodeficiency virus (HIV) has been a global public health priority. In 2013, the World Health Organization recommended antiretroviral therapy administration to all HIV-positive pregnant and breastfeeding women regardless of the CD4 cell count or clinical stage, referred to 'Option B+'. Ethiopia has had a high prevalence of mother-to-child transmission of HIV. The prevalence of transmission in breastfeeding mothers was 24% in 2012 and increased to more than 30% in 2015. Thus, the aim of this study was to determine the prevalence of HIV transmission and its associations among infants born to HIV-positive mothers who had enrolled with the five Amhara regional state referral hospitals' prevention of mother-to-child HIV transmission departments, Ethiopia. METHODS The study used a retrospective single cohort design, and simple random sampling with proportional allocation to select the medical records of 217 exposed infants. The data collected from each hospital were documented from January 1, 2014 to May 30, 2017. The cumulative incidence and prevalence of HIV transmission among exposed infants in the region were presented using figures and tables. RESULTS The prevalence of HIV transmission among exposed infants at enrollment to the program was 2.3% (five cases) (95% CI, 0.5-4.6%), whereas the prevalence of HIV transmission among exposed infants on completion of the program was 3.7% (8) (95% CI, 1.4-6.5%). The cumulative incidence of transmission on completing the program was 1.6% (3) (95% CI, 0.0-3.2%). CONCLUSIONS In contrast to the expected outcome of the World Health Organization's 'Option B+' guidelines regarding HIV transmission, this study found the cumulative incidence of HIV transmission on completing the program and the overall prevalence of HIV infection to be high. Although some studies have reported significant reductions in mother-to-child transmission of HIV, there are still considerable challenges in preventing this transmission in the Amhara region.

Abstract
Background Vertical transmission of Human Immunodeficiency Virus (HIV) is the primary route of infection among children. Ethiopia is among the top ten countries in the world with the highest burden of HIV infections among children. Therefore we aimed to assess mother to child transmission (MTCT) of HIV and associated factors among HIV exposed infants (HEIs). Methods A cross-sectional study was conducted using retrospective data collected from HEIs paired with their mothers who had received the services in prevention of mother to child transmission (PMTCT) programs from January 2014 to December 2017 in public health facilities in Dessie town. Data of a total of 313 HEIs paired with their mothers were obtained by using semi-structured data extraction proforma from their medical records. The data were processed in Epi-info version 7.1.2.0 and analyzed using SPSS version 22. Crude and adjusted odds ratios with their 95% confidence intervals and p-value were used to identify significant factors. Results The prevalence of HIV among exposed infants was 3.8%. Absence of maternal antenatal care visit (AOR = 4.6, 95% CI: 1.17–17.99), home delivery (AOR = 4.2, 95% CI: 1.04 −16.76), absence of antiretroviral intervention to the mother (AOR= 5.7, 95% CI: 1.10–29.36), and failure to initiate nevirapine prophylaxis for the infant (AOR = 5.3, 95% CI: 1.11 −25.44) were significant factors of MTCT of HIV. Conclusion Prevalence of MTCT of HIV was low (3.8%) in Dessie town public health facilities. Having ANC visit, delivery at health facility, maternal ARV drug intake, and infant ARV prophylaxis were the significant protective factors against MTCT of HIV. Promoting ANC service utilization among pregnant women and providing counseling as well as setting up linkage with PMTCT and giving ARV intervention to all HIV positive pregnant women and timely initiation of NVP prophylaxis to all HEIs should be recommended by the minister of health and health facilities.

Abstract
BACKGROUND Infants infected during pregnancy or while breastfeeding requires early HIV diagnosis at 6 weeks after birth to identify HIV infection and timely treatment. The objective of this work was to determine the prevalence and associated risk factors of HIV among HIV exposed infants in the Tigray regional state, Northern Ethiopia. METHODS A cross-sectional study was conducted on 350 exposed infants born to HIV seropositive mothers from September 01 to December 30, 2016. Convenient consecutive sampling technique was employed to enroll HIV exposed infants from age 6 weeks to 18 months attending prevention of mother to child transmission (PMCT) clinic at Anti Retroviral Therapy (ART) site facility in Tigray, Ethiopia. Sociodemographic data and associated risk factors were collected using a structured questionnaire. Dried Blood Spot (DBS) samples were collected from each infant and transported by post to Tigray Health Research Institute to detect HIV infection using real-time Polymerase Chain Reaction (PCR). Data were entered into EPI Info version 7, exported and analyzed using Statistical Package for Social Sciences (SPSS) version 22. p-value less than 0.05 was deemed to be statistically significant by Fisher's exact test. RESULTS Three hundred forty infants (175 males, 165 females) met the criteria for selection during the completion of the study and the overall HIV prevalence was found to be 2.1% (n = 7). The majority of infants were from urban areas (n = 246, 72.4%). 45.5% (5/11, p = 0.001) infants were without ARV prophylaxis, 60% (3/5, p = 0.001) infants born to mothers who did not take maternal PMTCT intervention, 43% (3/7, p = 0.001) infants born to mothers who were not enrolled to ART care, and 6.1% (4/66, p = 0.029) infants of unmarried mothers showed statistically significant difference. CONCLUSIONS The overall prevalence of HIV among exposed infants was high but lower than the Millennium Development Goal targets. In order to eliminate the mother to child HIV transmission (MTCT) ARV prophylaxis in infants must be strengthened, and enrollment of HIV positive pregnant women to PMTCT and ART care and treatment is needed.

Abstract
OBJECTIVE We measured the effect of point-of-care (POC) early infant HIV testing on antiretroviral therapy initiation rates and retention in care among infants in Mozambique. DESIGN A cluster-randomized trial was conducted in 16 primary healthcare centres providing either on-site POC arm (n = 8) or referred laboratory [standard-of-care (SOC) arm; n = 8] infant HIV testing. METHODS The primary outcomes were the proportion of HIV-positive infants initiating antiretroviral therapy within 60 days of sample collection, and the proportion of HIV-positive infants who initiated antiretroviral therapy that were retained in care at 90 days of follow-up. RESULTS The proportion of HIV-positive infants initiating antiretroviral therapy within 60 days of sample collection was 89.7% (157 of 175) for the POC arm and 12.8% (13 of 102) for the SOC arm [relative risk (RR)(adj) 7.34; P < 0.001]. The proportion of HIV-positive infants who initiated antiretroviral therapy that were retained in care at 90 days of follow-up was 61.6% (101 of 164) for the POC arm and 42.9% (21 of 49) for the SOC arm [RR(adj) 1.40; P < 0.027]. The median time from sample collection to antiretroviral therapy initiation was less than 1 day (interquartile range: 0-1) for the POC arm and 127 days (44-154; P < 0.001) for the SOC arm. CONCLUSION POC infant HIV testing enabled clinics to more rapidly diagnose and provide treatment to HIV-infected infants. This reduced opportunities for pretreatment loss to follow-up and enabled a larger proportion of infants to receive test results and initiate antiretroviral therapy. The benefits of faster HIV diagnosis and antiretroviral treatment may also improve early retention in care.

Prevention of Mother-to-Child Transmission and Early Real-Time DNA Polymerase Chain Reaction Results Among HIV-Exposed Infants in Bujumbura, Burundi. East Afr Health Res J 2018; 2:112-117. [PMID: 34308181 PMCID: PMC8279233 DOI: 10.24248/eahrj-d-18-00003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2018] [Accepted: 10/05/2018] [Indexed: 11/20/2022] Open
Abstract
Background: Prevention of mother-to-child transmission (PMTCT) programmes aim to both eliminate vertical transmission of HIV and optimise the health and survival of infants born with HIV. Therefore, early infant diagnosis (EID) of HIV infection via DNA polymerase chain reaction (PCR) testing is a key component of PMTCT programming. We assessed the effectiveness of EID and PMTCT interventions at health-care facilities in Bujumbura, Burundi. Methods: This was a prospective analytical study of infants born to HIV-positive mothers on antiretroviral therapy (ART), who were followed from December 2016 to March 2017 at 3 centres providing PMTCT services in Bujumbura. Babies enrolled in this study received once-daily nevirapine from birth through to 6 weeks of life, after which HIV DNA PCR testing was conducted. Results: Of 122 HIV-exposed infants, 60 were boys and 62 were girls. The mother-to-child transmission rate at 6 weeks of life was 0.9%. Eighty-three (68%) of the women had commenced ART before pregnancy and 39 (32%) during pregnancy. The mean CD4 lymphocyte count was 653±308 cells/μl. Ninety-two (75.4%) of the pregnancies were planned, and 98 (80%) of the births were via spontaneous vaginal delivery. After birth, 111 (91.0%) infants were exclusively breastfed, and 11 (9.0%) infants received exclusive replacement feeding. Conclusion: There was a low rate of transmission of HIV from women taking ART to children who were given nevirapine for the first 6 weeks of life. Infants of HIV-positive women can live healthy lives free from HIV infection if their mothers participate in PMTCT programmes.

Implementation effectiveness of revised (post-2010) World Health Organization guidelines on prevention of mother-to-child transmission of HIV using routinely collected data in sub-Saharan Africa: A systematic literature review.

Abstract
BACKGROUND To synthesize and evaluate the impact of implementing post-2010 World Health Organization (WHO) prevention of mother-to-child transmission (PMTCT) guidelines on attainment of PMTCT targets. METHODS Retrospective and prospective cohort study designs that utilized routinely collected data with a focus on provision and utilization of the cascade of PMTCT services were included. The outcomes included the proportion of pregnant women who were tested during their antenatal clinic (ANC) visits; mother-to-child transmission (MTCT) rate; adherence; retention rate; and loss to follow-up (LTFU). RESULTS Of the 1210 references screened, 45 met the inclusion criteria. The studies originated from 14 countries in sub-Saharan Africa. The highest number of studies originated from Malawi (10) followed by Nigeria and South Africa with 7 studies each. More than half of the studies were on option A while the majority of option B+ studies were conducted in Malawi. These studies indicated a high uptake of human immunodeficiency virus (HIV) testing ranging from 75% in Nigeria to over 96% in Zimbabwe and South Africa. High proportions of CD4 count testing were reported in studies only from South Africa despite that in most of the countries CD4 testing was a prerequisite to access treatment. MTCT rate ranged from 1.1% to 15.1% and it was higher in studies where data were collected in the early days of the WHO 2010 PMTCT guidelines. During the postpartum period, adherence and retention rate decreased, and LTFU increased for both HIV-positive mothers and exposed infants. CONCLUSION Irrespective of which option was followed, uptake of antenatal HIV testing was high but there was a large drop off along later points in the PMTCT cascade. More research is needed on how to improve later components of the PMTCT cascade, especially of option B+ which is now the norm throughout sub-Saharan Africa.
