Abstract Background Innovative approaches are needed to limit antimalarial resistance evolution. Understanding the role of intermittent preventive treatment in pregnancy (IPTp) on the selection for resistance and the impact such selection has on pregnancy outcomes can guide future interventions. Methods Plasmodium falciparum isolates (n = 914) from 2 randomized clinical trials were screened for pfmdr1 copy number variation and pfcrt, pfmdr1, pfdhfr, and pfdhps resistance markers. The trials were conducted between 2010 and 2013 in Benin, Gabon, Kenya, and Mozambique to establish the efficacy of IPTp-mefloquine (MQ) compared with IPTp-sulphadoxine-pyrimethamine (SP) in human immunodeficiency virus (HIV)-uninfected and to IPTp-placebo in HIV-infected women. Results In HIV-uninfected women, the prevalence of pfcrt mutants, pfdhfr/pfdhps quintuple mutants, and pfmdr1 copy number was similar between women receiving IPT-SP and IPTp-MQ. However, prevalence of pfmdr1 polymorphism 86Y was lower in the IPTp-MQ group than in the IPTp-SP group, and within the IPTp-MQ group it was lower at delivery compared with recruitment. No effect of IPTp-MQ on resistance markers was observed among HIV-infected women. The carriage of resistance markers was not associated with pregnancy outcomes. Conclusions Selection of wild-type pfmdr1 polymorphism N86 by IPTp-MQ highlights the strong selective pressure IPTp can exert and the opportunity for using negative cross-resistance in drug choice for clinical treatment and IPTp.

Abstract Background Harmful maternal and neonatal health outcomes result from malaria in pregnancy, the prevention of which primarily relies on intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP). WHO recommends IPTp-SP in sub-Saharan Africa, but implementation is highly heterogeneous and often sub-optimal in terms of the number of doses and their timing. In this study, we assessed the impact of this heterogeneity on malaria in pregnancy, mainly with respect to submicroscopic Plasmodium falciparum infections. Methods We used data from 273 Beninese women followed throughout pregnancy. Screening for P. falciparum infections, using both microscopy- and polymerase chain reaction (PCR) -based methods, was performed monthly, and information on IPTp-SP dose was collected. Gestational age was estimated by repeated ultrasound scans. Using a negative binomial model, we investigated the effect of IPTp-SP doses and timing, after 17 weeks of gestation, on the number of P. falciparum infections, focusing on submicroscopic infections detectable only by PCR. Results At least two IPTp-SP doses were taken by 77.3% of the women. The median gestational age at first IPTp-SP dose was 22 weeks. A late first IPTp-SP dose (>21.2 weeks) was marginally associated with an increased number of P. falciparum infections (adjusted incidence rate ratio [aIRR] =1.3; p=0.098). The number of IPTp-SP doses was not associated with the number of submicroscopic infections (aIRR=1.2, p=0.543). Conclusion A late first IPTp-SP dose fail to provide optimal protection against P. falciparum, especially submicroscopic infections. This highlights the need for a new antimalarial drug for IPTp that could be taken early in pregnancy.

Abstract Background Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is a key malaria prevention strategy in areas with moderate to high transmission. As part of the TIPTOP (Transforming IPT for Optimal Pregnancy) project, baseline information about IPTp coverage was collected in eight districts from four sub-Saharan countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria. Methods Cross-sectional household surveys were conducted using a multistage cluster sampling design to estimate the coverage of IPTp and antenatal care attendance. Eligible participants were women of reproductive age who had ended a pregnancy in the 12 months preceding the interview and who had resided in the selected household during at least the past 4 months of pregnancy. Coverage was calculated using percentages and 95% confidence intervals. Results A total of 3911 women were interviewed from March to October 2018. Coverage of at least three doses of IPTp (IPTp3+) was 22% and 24% in DRC project districts; 23% and 12% in Madagascar districts; 11% and 16% in Nigeria local government areas; and 63% and 34% in Mozambique districts. In DRC, Madagascar and Nigeria, more than two-thirds of women attending at least four antenatal care visits during pregnancy received less than three doses of IPTp. Conclusions The IPTp3+ uptake in the survey districts was far from the universal coverage. However, one of the study districts in Mozambique showed a much higher coverage of IPTp3+ than the other areas, which was also higher than the 2018 average national coverage of 41%. The reasons for the high IPTp3+ coverage in this Mozambican district are unclear and require further study.

Mutant Haplotype

Abstract Mutations in the Plasmodium falciparum genes Pfdhfr and Pfdhps, particularly the sextuple mutant haplotype threatens the antimalarial effectiveness of sulfadoxine-pyrimethamine as intermittent preventive treatment during pregnancy (IPTp). To explore the impact of sextuple mutant haplotype infections on outcome measures after provision of IPTp-SP, we monitored birth outcomes in women followed from prior to conception or from the first trimester until delivery. Women infected with sextuple haplotypes in early 2 nd trimester specifically, delivered newborns with a lower birth weight (-267g, 95% CI -454; -59, p=0·01) compared to women who did not have malaria during pregnancy and women infected with less SP resistant haplotypes (-461g, 95% CI -877; -44, p=0·03). Thus, sextuple haplotype infections seems to impact the effectiveness of SP for IPTp and directly impact birth outcome by lowering birth weight. Close monitoring and targeted malaria control during early pregnancy is therefore crucial to improve birth outcomes.

Objective: Malaria is a major cause of indirect maternal death. In the last two decades several efforts have been made to combat the menace of this disease especially among pregnant women and children in developing countries. Directly observed therapy (DOT) was recommended to enhance the uptake of intermittent preventive treatment (IPT) of malaria with sulfadoxine – pyrimethamine among pregnant women. Due to challenges involved in the practice of DOT especially with regards to shortage of man power and clean water in rural areas, there is need to evaluate impact of DOT on the effectiveness of treatment. Material and Methods: A cohort study was carried out among 320 healthy pregnant women receiving ante natal care with equal assignment of subjects. The study group (160) received two doses of IPT by DOT while 160 matched controls were given prescription for self- drug administration at home. Malaria tests were done using microscopy method and the hemoglobin values determined using centrifuge one month after the second dose of IPT. Umbilical cord blood samples were obtained for a repeat microscopy at delivery. Results: The results showed that there were no statistical significant differences in the venous blood parasitemia, placental parasitemia and anaemia between the DOT group and the control group (P = 0.215; P = 0.100; P = 0.966) respectively. Lower social class was the main predictor of anaemia in pregnancy (P = 0.032). Conclusion: The delivery of IPT through DOT may not influence uptake in some settings. Effort may need to be channeled into ante natal education and women empowerment.
