RESUMEN

Malaria in pregnancy (MiP) intervention coverage, especially intermittent preventive treatment in pregnancy (IPTp), lags behind other global malaria indicators. In 2020, across Africa, only 32% of eligible pregnant women received at least three IPTp doses, despite high antenatal care attendance. We conducted a secondary analysis of data collected during Outreach Training and Supportive Supervision visits from 2019 to 2020 to assess quality of care and explore factors contributing to providers' competence in providing IPTp, insecticide-treated nets, malaria case management, and respectful maternity care. Data were collected during observations of provider-patient interactions in six countries (Cameroon, Cote d'Ivoire, Ghana, Kenya, Mali, and Niger). Competency scores (i.e., composite scores of supervisory checklist observations) were calculated across three domains: MiP prevention, MiP treatment, and respectful maternity care. Scores are used to understand drivers of competency, rather than to assess individual health worker performance. Country-specific multilinear regressions were used to assess how competency score was influenced by commodity availability, training, provider gender and cadre, job aid availability, and facility type. Average competency scores varied across countries: prevention (44-90%), treatment (78-90%), and respectful maternity care (53-93%). The relative association of each factor with competency score varied. Commodity availability, training, and access to job aids correlated positively with competency in multiple countries. To improve MiP service quality, equitable access to training opportunities for different cadres, targeted training, and access to job aids and guidelines should be available for providers. Collection and analysis of routine supervision data can support tailored actions to improve quality MiP services.

RESUMEN

Young women in sub-Saharan Africa are a group at increased risk for malaria in pregnancy. Early antenatal care (ANC) seeking makes it more likely that women will receive the recommended doses of intermittent preventive treatment of malaria in pregnancy. This study used data from national Malaria Behavior Surveys conducted in Malawi and the Democratic Republic of the Congo (DRC) in 2021 to explore the association between intention to attend ANC in the first trimester for a future pregnancy (early ANC intention) and psychosocial factors among women aged 15-49 years. Eight psychosocial factors related to ANC and based on the ideation model were included, including knowledge, attitudes, and self-efficacy. The study used multivariable logistic regression models controlling for demographic characteristics to evaluate associations between early ANC intention and the individual ideational factors and the composite measure. Analysis included 2,148 women aged 15-49 years (Malawi: 827, DRC: 1,321). Antenatal care ideation was lower among young (aged 15-20 years) than among older (aged 21-49 years) women in Malawi. Young mothers with higher ANC ideation were more likely to intend to attend ANC early in their next pregnancy in both countries. Specific ideational factors associated with intention to attend ANC early varied by country and included positive attitudes, knowledge of ANC, and positive self-efficacy. In Malawi and the DRC, youth-friendly social and behavior change interventions to increase ANC-related ideation could increase future early ANC attendance among young women to improve malaria and birth outcomes.

RESUMEN

BACKGROUND: Malaria in pregnancy (MIP) increases the risk of poor maternal and infant outcomes. To reduce these risks, WHO recommends insecticide-treated net (ITN) use, intermittent preventive treatment during pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP), and prompt case management. However, uptake of these interventions remains sub-optimal in Madagascar. A scoping review was conducted to determine the breadth and depth of information available during 2010-2021 about Madagascar's MIP activities and to identify barriers and facilitators to MIP interventions uptake. METHODS: PubMed, Google Scholar, and USAID's files (Development Experience Catalog) were searched using the terms "Madagascar AND pregnancy AND malaria," and reports and materials from stakeholders were collected. Documents in English and French from 2010 to 2021 with data regarding MIP were included. Documents were systematically reviewed and summarized; results were captured in an Excel database. RESULTS: Of 91 project reports, surveys and published articles, 23 (25%) fell within the stated time period and contained relevant data on MIP activities in Madagascar and were categorized accordingly: eight (35%) quality of care, including health facility readiness, provider knowledge and commodity availability; nine (39%) care-seeking behaviour; and, six (26%) prevention of MIP. Key barriers were identified: nine articles mentioned SP stockouts; seven found limitations of provider knowledge, attitudes, and behaviours (KAB) regarding MIP treatment and prevention; and, one reported limited supervision. MIP care seeking and prevention barriers and facilitators included women's KAB regarding MIP treatment and prevention, distance, wait times, poor service quality, cost, and/or unwelcoming providers. A 2015 survey of 52 health facilities revealed limited client access to antenatal care due to financial and geographic barriers; two 2018 surveys revealed similar findings. Self-treatment and care-seeking delays were reported even when distance was not a barrier. CONCLUSION: Among the studies and reports on MIP in Madagascar, the scoping review frequently noted barriers that could be mitigated by reducing stockouts, improving provider knowledge and attitudes, refining MIP communication, and improving service access. There is a need for coordinated efforts to address the identified barriers is the key implication of the findings.

RESUMEN

Background: RH5 is the leading vaccine candidate for the Plasmodium falciparum blood stage and has shown impact on parasite growth in the blood in a human clinical trial. RH5 binds to Ripr and CyRPA at the apical end of the invasive merozoite form, and this complex, designated RCR, is essential for entry into human erythrocytes. RH5 has advanced to human clinical trials, and the impact on parasite growth in the blood was encouraging but modest. This study assessed the potential of a protein-in-adjuvant blood stage malaria vaccine based on a combination of RH5, Ripr and CyRPA to provide improved neutralizing activity against P. falciparum in vitro. Methods: Mice were immunized with the individual RCR antigens to down select the best performing adjuvant formulation and rats were immunized with the individual RCR antigens to select the correct antigen dose. A second cohort of rats were immunized with single, double and triple antigen combinations to assess immunogenicity and parasite neutralizing activity in growth inhibition assays. Results: The DPX® platform was identified as the best performing formulation in potentiating P. falciparum inhibitory antibody responses to these antigens. The three antigens derived from RH5, Ripr and CyRPA proteins formulated with DPX induced highly inhibitory parasite neutralising antibodies. Notably, RH5 either as a single antigen or in combination with Ripr and/or CyRPA, induced inhibitory antibodies that outperformed CyRPA, Ripr. Conclusion: An RCR combination vaccine may not induce substantially improved protective immunity as compared with RH5 as a single immunogen in a clinical setting and leaves the development pathway open for other antigens to be combined with RH5 as a next generation malaria vaccine.

RESUMEN

BACKGROUND: Burkina Faso is among ten countries with the highest rates of malaria cases and deaths in the world. Delivery and coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) is insufficient in Burkina Faso; In a 2016 survey, only 22% of eligible women had received their third dose of IPTp. It is also an extremely rural country and one with an established cadre of community healthcare workers (CHWs). To better meet the needs of pregnant women, an enhanced programme was established to facilitate distribution of IPTp at the community level by CHWs. METHODS: In order to assess the perceptions of CHWs and facility healthcare workers (HCWs) involved in this programme rollout, semi-structured interviews were conducted at three high malaria burden health districts in Burkina Faso. Interviews were conducted at baseline with 104 CHWs and 35 HCWs prior to the introduction of community based IPTp (c-IPTp) to assess capacity and any areas of concern. At endline, interviews were conducted with 29 CHWs and 21 HCWs to identify key facilitators and suggestions for further implementation of the c-IPTp programme. RESULTS: CHWs reported feeling capable of supporting c-IPTp delivery and facilitating linkage to antenatal care (ANC). They noted that the opportunity for enhanced training and close and ongoing connections with facility HCWs and supportive supervision were imperative. Both CHWs and HCWs perceived this approach as acceptable to community members and noted the importance of close community engagement, monthly meetings between CHWs and facility HCWs, and maintaining regular supplies of sulfadoxine-pyrimethamine (SP). Those interviewed noted that it was beneficial to have the involvement of both female and male CHWs. CONCLUSIONS: Community-based delivery of IPTp was feasible and acceptable to both facility HCWs and CHWs. This approach has the potential to strengthen delivery and uptake of IPTp and ANC both in Burkina Faso and across the region.

RESUMEN

Large household surveys performed to estimate coverage rates for various health interventions, including intermittent preventive treatment, depend on recall. Many studies question the validity of recalled data. Regarding vaccine coverage rates, it is standard practice to validate responses using medical history cards. To validate the coverage rates of intermittent preventive treatment during pregnancy reported by large household surveys, recalled coverage rates were compared with antenatal care card data in Benin, Ghana, Malawi, and Tanzania. The results indicated that recall was comparable to the coverage rates provided indicated by the antenatal care cards. These findings suggest that intermittent preventive treatment coverage rates reported by large household surveys performed using recalled data are valid.

RESUMEN

BACKGROUND: Malaria in pregnancy is responsible for 8-14% of low birth weight and 20% of stillbirths in sub-Saharan Africa. To prevent these adverse consequences, the World Health Organization recommends intermittent preventive treatment of pregnant women (IPTp) with sulfadoxine-pyrimethamine be administered at each ANC visit starting as early as possible in the second trimester. Global IPTp coverage in targeted countries remains unacceptably low. Community delivery of IPTp was explored as a means to improve coverage. METHODS: A cluster randomized, controlled trial was conducted in 12 health facilities in a 1:1 ratio to either an intervention group (IPTp delivered by CHWs) or a control group (standard practice, with IPTp delivered at HFs) in three districts of Burkina Faso to assess the effect of IPTp administration by community health workers (CHWs) on the coverage of IPTp and antenatal care (ANC). The districts and facilities were purposively selected taking into account malaria epidemiology, IPTp coverage, and the presence of active CHWs. Pre- and post-intervention surveys were carried out in March 2017 and July-August 2018, respectively. A difference in differences (DiD) analysis was conducted to assess the change in coverage of IPTp and ANC over time, accounting for clustering at the health facility level. RESULTS: Altogether 374 and 360 women were included in the baseline and endline surveys, respectively. At baseline, women received a median of 2.1 doses; by endline, women received a median of 1.8 doses in the control group and 2.8 doses in the intervention group (p-value < 0.0001). There was a non-statistically significant increase in the proportion of women attending four ANC visits in the intervention compared to control group (DiD = 12.6%, p-value = 0.16). By the endline, administration of IPTp was higher in the intervention than control, with a DiD of 17.6% for IPTp3 (95% confidence interval (CI) - 16.3, 51.5; p-value 0.31) and 20.0% for IPTp4 (95% CI - 7.2, 47.3; p-value = 0.15). CONCLUSIONS: Community delivery of IPTp could potentially lead to a greater number of IPTp doses delivered, with no apparent decrease in ANC coverage.

RESUMEN

Malaria in pregnancy (MiP) contributes to devastating maternal and neonatal outcomes. Coverage of intermittent preventive treatment during pregnancy (IPTp) remains alarmingly low. Data was compiled from MiP programme reviews and performed a literature search on access to and determinants of IPTp. National malaria control and reproductive health (RH) policies may be discordant. Integration may improve coverage. Medication stock-outs are a persistent problem. Quality improvement programmes are often not standardized. Capacity building varies across countries. Community engagement efforts primarily focus on promotion of services. The majority of challenges can be addressed at country level to improve IPTp coverage.

RESUMEN

BACKGROUND: An estimated 30 million women give birth annually in malaria endemic areas of sub-Saharan Africa. Malaria in pregnancy is associated with an increased risk of adverse maternal and infant outcomes. To combat the adverse effects of MiP, the World Health Organization (WHO) recommends the provision of intermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) in areas of moderate to high malaria transmission. In 2012, the WHO updated its policy with respect to IPTp administration to recommend administration at each antenatal care visit in the second and third trimesters, with a minimum of three, rather than two, doses. While rapid improvements in coverage were expected, gains have occurred more slowly than anticipated. METHODS: The President's Malaria Initiative (PMI) assessed IPTp uptake before and after countries implemented the new WHO policy, and assessed how long it took for implementation to occur, using a combination of data from household surveys, routine health management information systems, and programmatic data provided to PMI. RESULTS: It took an average of 2 years for countries to complete the process of revising their IPTp policies, and it was not until 2015 that all 17 PMI countries had updated their policies. Policy dissemination and training had not been completed in several countries as of early 2018, and only seven countries had fully implemented the new policy including updating their antenatal care registers to collect information on IPTp3+ coverage. The coverage of IPTp1+, 2+, and 3+ has increased by 19, 16, and 13 percentage points since the revised IPTp policy adoption. DISCUSSION: Overall, coverage of both IPTp2+ and IPTp3+ has improved in recent years. The change in policy from a minimum of two to a minimum of three doses has likely contributed to these improvements. Progress has been slow, likely related to the complicated process of policy adoption exacerbated by the lag in measurement through national household surveys. The impact of future policy changes may be more readily seen if the policy change and implementation process were more streamlined and coordinated between key stakeholders (National Malaria Control Programmes and Reproductive Health Programmes), with more real-time data reporting.

RESUMEN

While much progress has been achieved globally in the fight against malaria, the significant financial investments made to date have not translated into scaled-up malaria in pregnancy (MiP) prevention efforts. Mothers and newborns remain at risk, and now is the time to refocus efforts. Against the backdrop of a new global health architecture embodied by the principles of Every Women, Every Child and driven by the work of the H6 Partnership, Global Financing Facility, strong bilaterals and key financiers, there is a new and timely juncture to advocate for MiP. Recent updates in the WHO Recommendations on Antenatal Care for a Positive Pregnancy Experience present an opportunity to strengthen MiP as a core maternal and child health issue and position MiP prevention as a priority.

RESUMEN

BACKGROUND: At least 39 sub-Saharan African countries have policies on preventing malaria in pregnancy (MIP), including use of long-lasting insecticidal nets (LLINs), intermittent preventive treatment with sulphadoxine-pyrimethamine (IPTp-SP) and case management. However, coverage of LLINs and IPTp-SP remains below international targets in most countries. One factor contributing to low coverage may be that MIP policies typically are developed by national malaria control programmes (NMCPs), but are implemented through national reproductive health (RH) programmes. METHODS: National-level MIP policies, guidelines, and training documents from NMCPs and RH programmes in Kenya, Mali, Mozambique, mainland Tanzania and Uganda were reviewed to assess whether they reflected WHO guidelines for prevention and treatment of MIP, and how consistent MIP content was across documents from the same country. Documents were compared for adherence to WHO guidance concerning IPTp-SP timing and dose, directly observed therapy, promotion and distribution of LLINs, linkages to HIV programmes and MIP case management. RESULTS: The five countries reviewed had national documents promoting IPTp-SP, LLINs and MIP case management. WHO guidance from 2004 frequently was not reflected: four countries recommended the first dose of IPTp-SP at 20 weeks or later (instead of 16 weeks), and three countries restricted the first and second IPTp-SP doses to specific gestational weeks. Documents from four countries provided conflicting guidance on MIP prevention for HIV-positive women, and none provided complete guidance on management of uncomplicated and severe malaria during pregnancy. In all countries, inconsistencies between NMCPs and RH programmes on the timing or dose of IPTp-SP were documented, as was the mechanism for providing LLINs. Inconsistencies also were found in training documents from NMCPs and RH programmes in a given country. Outdated, inconsistent guidelines have the potential to cause confusion and lead to incorrect practices among health workers who implement MIP programmes, contributing to low coverage of IPTp-SP and LLINs. CONCLUSIONS: MIP policies, guidelines and training materials are outdated and/or inconsistent in the countries assessed. Updating and ensuring consistency among national MIP documents is needed, along with re-orientation and supervision of health workers to accelerate implementation of the 2012 WHO Global Malaria Programme policy recommendations for IPTp-SP.
