Abstract Background: Malaria in pregnancy (MiP) remains a key cause of poor maternal and neonatal health outcomes. Two key strategies globally promoted to address MiP require pregnant women in malaria-endemic regions to sleep under insecticide-treated bed nets (ITNs) and take at least three doses of intermittent preventive treatment (IPTp) during pregnancy. Particularly in the African region where weak health systems grapple with prevailing socio-cultural and traditional practices, several multilevel factors influence the effective uptake of these strategies. This study explores the factors for the poor uptake of IPTp and use of ITNs in lower socio-economic communities in Nigeria. Methods: We conducted semi-structured interviews (SSI) and focus group discussions (FGD) with a total of 201 key stakeholders in 6 communities in Ogun State, South-western Nigeria. Twelve SSIs were conducted with traditional birth attendants (TBAs), faith-based birth attendants and healthcare providers operating in public health facilities. Community leaders (7), pregnant women (30) and 20 caregivers were also individually interviewed. Sixteen FGDs were conducted with multi- and first- time pregnant women grouped by location and pregnancy experiences. A thematic approach were used for data analysis. Results: At the individual and social levels, there is high general awareness of MiP, its consequences and ITNs but a low awareness of IPTp, with type of antenatal care (ANC) provider being a key factor influencing access to IPTp. Choice of type of ANC provider, which facilitates access to IPTp and ITNs, is influenced by experiences of relatives with ANC providers, attitudes of ANC providers and community perceptions of the type of ANC providers. Concurrent use of multiple ANC providers and ANC providers’ relationships further influence acceptability and coverage for IPTp and ITN use. At the health sector level, there is low awareness about preventive malarial strategies including IPTp among TBAs and faith-based birth attendants, in contrast to high IPTp awareness among public healthcare providers. Conclusion: The findings highlight several factors that influence the utilisation of IPTp services and call for greater synergy and sensitisation between the three groups of healthcare providers towards improving access to and acceptability of IPTp for improving maternal and child outcomes.

ABSTRACT Mefloquine was evaluated as an alternative for intermittent preventive treatment of malaria in pregnancy (IPTp) due to increasing resistance against the first-line drug sulfadoxine-pyrimethamine (SP). This study determined the pharmacokinetic characteristics of the mefloquine stereoisomers and the metabolite carboxymefloquine (CMQ) when given as IPTp in pregnant women. Also, the relationship between plasma concentrations of the three analytes and cord samples was evaluated, and potential covariates influencing the pharmacokinetic properties were assessed. A population pharmacokinetic analysis was performed with 264 pregnant women from a randomized controlled trial evaluating a single and a split-dose regimen of two 15-mg/kg mefloquine doses at least 1 month apart versus SP-IPTp. Both enantiomers of mefloquine and its carboxy-metabolite (CMQ), measured in plasma and cord samples, were applied for pharmacokinetic modelling using NONMEM 7.3. Both enantiomers and CMQ were described simultaneously by two-compartment models. In the split-dose group, mefloquine bioavailability was significantly increased by 5%. CMQ induced its own metabolism significantly. Maternal and cord blood concentrations were significantly correlated (r2 = 0.84) at delivery. With the dosing regimens investigated, prophylactic levels are not constantly achieved. A modeling tool for simulation of the pharmacokinetics of alternative mefloquine regimens is presented. This first pharmacokinetic characterization of mefloquine IPTp indicates adequate exposure in both mefloquine regimens; however, concentrations at delivery were below previously suggested threshold levels. Our model can serve as a valuable tool for researchers and clinicians to develop and optimize alternative dosing regimens for IPTp in pregnant women.

Abstract Background To improve the coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) in Africa, Medicines for Malaria Venture (MMV) developed, tested and validated a new packaging of sulfadoxine–pyrimethamine (SP), as well as specific communications tools designed to improve knowledge of IPTp and the motivation of women to adhere to it, particularly if it is distributed by community health workers (CHW). Methods This article describes and analyses the results of an empirical research carried out in the Democratic Republic of the Congo (DRC), Nigeria and Mozambique, to evaluate the perception and social acceptability of SP for healthcare providers, CHW and pregnant women, and to assess the ability of the new SP packaging and the communications tools to change their perception of SP and improve their attitudes towards IPTp. Results The results indicate that SP’s new individual packaging was perceived by pregnant women and healthcare providers as a “hygienic” and “safe”, with a specific identity. The graphics used in IPTp communications tools were modified according to the respondents’ feedback to make them more culturally and socially sensitive, and then validated. However, although the new blister packaging and IPTp communications tools generated greater confidence and motivation, SP side effects as well as preconceived ideas, particularly regarding its efficacy, remain a challenge that must be addressed to improve IPTp acceptance and compliance by healthcare providers and pregnant women. Conclusion This participatory approach to social research based on ongoing feedback to the graphic designer provided more empirical evidence to improve and adapt the textual and visual content of communication tools (SP blister packaging, leaflet, user guide) to local contexts and user preferences. Tested and validated in different socio-cultural and socio-political contexts, these tools provide a good basis for the promotion of IPTp in Africa.

Malaria in pregnancy is a major public health problem affecting women fetuses and new borns. Many studies highlight the critical importance of continuing the use of Insecticide Treated Nets (ITN) and Intermittent Preventive Treatment In Pregnancy (IPTp) among pregnant women to reduce the adverse consequences of malaria in pregnancy. This study was conducted in order to determine malaria prevalence in relation to the use ofITN and IPTp among the pregnant women in the study area. Five (5) ml of blood was obtained from each participant by the use of a sterile syringe and placed in a sterile EDTA container for laboratory analysis. The malaria parasite was detected by microscopic examination of Giemsa-stained thick blood films. Information on the use of ITN and IPTP was collected using administered questionnaire. A high prevalence of 78.4% was observed among the studied population. Although 74.4% of those that use ITN were positive for malaria parasite as against the 83.6% of those that reported not using the ITN, the difference was statistically not significant (p<0.05). 70.0% of those reported using IPTp were positive however, higher percentage was observed for those reported not using IPTp (83.7.0%). The difference was statistically significant in this case. This study has shown the influence of malaria prevention method during pregnancy on malaria infection and the need for targeted preventive starategies when  designing and implementing policies aimed at improving uptake of these measures during pregnancy in Gombe.

Abstract Background: Malaria in pregnancy remains a major public health problem. Annually, 125.2 million pregnant women worldwide are at risk of malaria infection including 30.3 million and 1 million pregnant women in Sub-Saharan Africa and Kenya respectively. The World Health Organization recommends that pregnant women in malaria endemic areas receive at least three doses of sulphadoxine pyrimethamine for intermittent preventive treatment of malaria in pregnancy (IPTp-SP) for optimal benefit. However, IPTp-SP optimal uptake is undesirably low in Kenya. This study investigated the prevalence of and factors influencing IPTp-SP optimal uptake in Sabatia Sub County, Western Kenya. Understanding the epidemiology of malaria in pregnancy is core for making decisions and setting priorities towards IPTp-SP optimization.Methods: This was a cross-sectional study conducted in Sabatia Sub County. Using a validated semi structured questionnaire, data were obtained from 372 randomly sampled post-delivery women aged 15 – 49 years who had a live birth within one year preceding the study. Women on cotrimoxazole prophylaxis during their pregnancy were excluded. Association between IPTp-SP uptake and independent variables was analysed using Pearson Chi-square and Fisher’s Exact test. Bivariate and multiple binary logistic regression analysed predictors of optimal IPTp-SP uptake.Results: Overall, 99.46 % of the respondents received at least one IPTp-SP dose. The prevalence of optimal IPTp-SP uptake was 79.57% (95% CI 75.47%, 83.67%). After multivariate analysis; gestational age at first antenatal care (ANC) visit (p = 0.04), frequency of ANC visits (p < 0.001), maternal knowledge of IPTp-SP benefits (p < 0.001), maternal knowledge of optimal SP dose (p = 0.03) and administration of sulphadoxine pyrimethamine at ANC clinic (p = 0.03) significantly predicted the optimal uptake of IPTp-SP.Conclusions: Optimal uptake of IPTp-SP is high in the study area. Efforts towards early and more frequent ANC attendance should be enhanced and sustained. Structured and targeted health education should be adopted and health workers should always administer SP drugs or explain to some pregnant women their ineligibility for initial IPTp-SP receipt. Future studies considering large sample drawn from the whole country and health workers’ perspective of the health system delivery factors are recommended.

Background: Dihydroartemisinin-piperaquine (DP) is a long-acting artemisinin combination treatment that provides effective chemoprevention and has been proposed as an alternative antimalarial drug for intermittent-preventive therapy in pregnancy (IPTp). Several pharmacokinetic studies have shown that dose adjustment may not be needed for the treatment of malaria in pregnancy with DP. However, there are limited data on the optimal dosing for IPTp. Objective: This study aimed to evaluate the population pharmacokinetics of piperaquine given as IPTp in pregnant women. Methods: Pregnant women were enrolled in clinical trials conducted in Kenya and Indonesia and treated with standard 3-day courses of DP, administered in 4-8 weeks intervals from the second trimester until delivery. Pharmacokinetic blood samples were collected for piperaquine drug measurements before each treatment round, time of breakthrough symptomatic malaria, and at delivery. Piperaquine population pharmacokinetic properties were investigated using nonlinear mixed-effects modelling with a prior approach. Results: In total data from 366 Kenyan and 101 Indonesian women were analysed. The pharmacokinetic properties of piperaquine were adequately described using a flexible transit absorption (n=5) followed by a three-compartment disposition model. Gestational age did not affect the pharmacokinetic parameters of piperaquine. After three rounds of monthly IPTp, 9.45% (95% CI: 1.8-26.5) of pregnant women had trough piperaquine concentrations below the suggested target concentration (10.3 ng/mL). Translational simulations suggest that providing the full treatment dose of DP at monthly intervals provides sufficient protection to prevent malaria infection. Conclusions: Monthly administration of a DP has the potential to offer optimal prevention of malaria during pregnancy.

AbstractDespite the clinically proven advantages of intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP), utilisation has been low in many African countries. To increase uptake and achieve the desired effect, the World Health Organization revised the policy to a monthly administration. Assessing the coverage and impact of the revised policy on pregnancy and neonatal outcomes is, therefore, a necessity. A 2-parallel cross-sectional hospital-based study was carried out among pregnant women attending first antenatal care (ANC) and delivery. Maternal and cord blood samples were assayed for malaria parasites by quantitative PCR targeting both the 18S rDNA and the acidic terminal segment of Plasmodium falciparum var genes, and plasma SP levels were measured by liquid chromatography coupled to tandem mass spectrometry. Parasite prevalence was similar between the two study sites but decreased significantly between the first ANC (9% or 43%) and delivery (4% or 11%) based on the qPCR target. At delivery, 64.5% of women received ≥3 IPTp-SP dose, 15.5% received 2 doses and 6% had 1 dose. Taking ≥3 IPTp-SP doses was associated with an average birth weight increase of more than 0.165 kg. IPTp-SP uptake was associated with plasma SP level at delivery (OR = 32.3, p ≤ 0.005, 95% CI (13.3;78.4) for those that reported ≥3 IPTp-SP doses) while the same trend of improved birth weight was observed with high plasma SP levels. The new IPTp policy is well implemented and well utilised by women in the sites considered in this study and translates to the improved birth weight observed. This study confirms the interest and the clinical benefit expected from this policy change.

Abstract Background Malaria in pregnancy doubles the risk of low birthweight and causes 11% of all neonatal deaths in sub-Saharan Africa. To prevent these and other adverse health consequences, the World Health Organization recommends administering intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine–pyrimethamine for all pregnant women at each antenatal care (ANC) visit, starting as early as possible in the second trimester. The target is for countries to administer a minimum of three doses (IPTp3+) to at least 85% of pregnant women. Methods A cluster randomized, controlled trial was conducted to assess the effect of delivery of IPTp by community health workers on the coverage of IPTp3+ and ANC visits in Malawi. Community delivery of IPTp was implemented within two districts in Malawi over a 21-month period, from November 2018 to July 2020. In control sites, IPTp was delivered at health facilities. Representative samples of women who delivered in the prior 12 months were surveyed at baseline (n=370, December 2017) and endline (n=687, August 2020). A difference in differences analysis was conducted to assess the change in coverage of IPTp and ANC over time, accounting for clustering at the health facility level. Results Overall IPTp coverage increased over the study period. At baseline, women received a mean of 2.3 IPTp doses (range 0–5 doses) across both arms, and at endline, women received a mean of 2.8 doses (range 0–9 doses). Despite overall increases, the change in IPTp3+ coverage was not significantly different between intervention and control groups (6.9%, 95% CI: -5.9%, 19.6%). ANC4+ coverage increased significantly in the intervention group compared with the control group, with a difference-in-differences of 25.3 percentage points (95% CI: 1.3%, 49.3%). Conclusions In order to reduce the burden of malaria in pregnancy, new strategies are needed to improve uptake of effective interventions such as IPTp. While community health workers’ delivery of IPTp did not increase uptake in this study, they may be effective in other settings or circumstances. Further research can help identify the health systems characteristics that are conducive to community delivery of IPTp and the operational requirements for effective implementation.
