BACKGROUND: Limited qualitative research has been performed in India to investigate views and behaviours of pregnant women regarding malaria despite the threat of malaria-related adverse maternal and neonatal outcomes. To address this gap, a comprehensive study on malaria prevention and treatment attitudes, knowledge and behaviour among pregnant women in India was conducted. METHODS: Pregnant women and healthcare workers (HCWs), encompassing clinic-based providers, traditional birth attendants, and auxiliary nurse-midwives were enrolled for in-depth interviews (IDIs) at 7 hospital sites and nearby communities in Jharkhand and Chhattisgarh States...

Rationale: The availability of therapeutics to treat pregnancy complications is severely lacking, mainly due to the risk of harm to the fetus. In placental malaria, Plasmodium falciparum- infected erythrocytes (IEs) accumulate in the placenta by adhering to chondroitin sulfate A (CSA) on the surfaces of trophoblasts. Based on this principle, we have developed a method for targeted delivery of payloads to the placenta using a synthetic placental CSA-binding peptide (plCSA-BP) derived from VAR2CSA, a CSA-binding protein expressed on IEs...

BACKGROUND: Malaria chemoprophylaxis options in pregnancy are limited, and atovaquone-proguanil (AP) is not recommended because of insufficient safety evidence. An anonymous, internet-based survey was disseminated to describe outcomes of pregnancies accidentally exposed to AP. Outcomes of interest included miscarriage (defined as pregnancy loss before 20 weeks), stillbirth (defined as pregnancy loss at or after 20 weeks), preterm birth or live birth prior to 37 weeks, and the presence of congenital anomalies...

Spontaneous splenic hematoma occurring during pregnancy is a rare entity. It often occurs in preexisting pathology of the spleen such as thalassemia or infectious etiologies such as malaria, typhoid, dengue, or infectious mononucleosis but most commonly after a trauma. The occurrence of splenic hematoma during pregnancy without any underlying cause is rare. Here, we present such a case and the diagnostic dilemma associated with it.

BACKGROUND: Difficulties to disentangle the protective versus exposure role of anti-malarial antibodies hamper the identification of clinically-relevant immune targets. Here, factors affecting maternal IgG and IgMs against Plasmodium falciparum antigens, as well as their relationship with parasite infection and clinical outcomes, were assessed in mothers and their children. Antibody responses among 207 Mozambican pregnant women at delivery against MSP119 , EBA175, AMA1, DBLα and parasite lysate (3D7, R29 and E8B parasite lines), as well as the surface of infected erythrocytes, were assessed by enzyme-linked immunosorbent assay and flow cytometry...

BACKGROUND: Increased susceptibility to malaria during pregnancy is not completely understood. Cellular immune responses mediate both pathology and immunity but the effector responses involved in these processes have not been fully characterized. Maternal and fetal cytokine and chemokine responses to malaria at delivery, and their association with pregnancy and childhood outcomes, were investigated in 174 samples from a mother and child cohort from Mozambique. Peripheral and cord mononuclear cells were stimulated with Plasmodium falciparum lysate and secretion of IL-12p70, IFN-γ, IL-2, IL-10, IL-8, IL-6, IL-4, IL-5, IL-1β, TNF, TNF-β was quantified in culture supernatants by multiplex flow cytometry while cellular mRNA expression of IFN-γ, TNF, IL-2, IL-4, IL-6, IL-10 and IL-13 was measured by quantitative PCR...

We measured the prevalence of malaria in pregnancy and estimated its impact on birth weight and length and maternal hemoglobin in 1,180 women from Juruá Valley, the main malaria hotspot in Brazil. Antenatal malaria episodes, 74.6% of them due to Plasmodium vivax , were microscopically diagnosed in 8.0% of the women and were associated with an average reduction in birth weight z -scores of 0.35 (95% confidence interval [CI] = 0.14-0.57) and in birth length z -scores of 0.31 (95% CI = 0.08-0.54), compared with malaria-free pregnancies...

REVIEW
Domenico Plantone, Tatiana Koudriavtseva
The process of finding new therapeutic indications for currently used drugs, defined as 'repurposing', is receiving growing attention. Chloroquine and hydroxychloroquine, with an original indication to prevent or cure malaria, have been successfully used to treat several infectious (HIV, Q fever, Whipple's disease, fungal infections), rheumatological (systemic lupus erythematosus, antiphospholipid antibody syndrome, rheumatoid arthritis, Sjögren's syndrome), and other immunological diseases. Indeed, they have anti-inflammatory, immunomodulating, anti-infective, antithrombotic, and metabolic effects...

Introduction: For every woman who dies during pregnancy and childbirth, many more suffer ill-health, the burden of which is highest in low-resource settings. We sought to assess the extent and types of maternal morbidity. Methods: Descriptive observational cross-sectional study at primary-level and secondary-level healthcare facilities in India, Pakistan, Kenya and Malawi to assess physical, psychological and social morbidity during and after pregnancy. Sociodemographic factors, education, socioeconomic status (SES), quality of life, satisfaction with health, reported symptoms, clinical examination and laboratory investigations were assessed...

Background: Pregnant women are more susceptible to P. falciparum than before pregnancy, and infection has consequences for both mother and offspring. WHO recommends that pregnant woman in areas of transmission receive intermittent preventive treatment starting in the second trimester. Consequently, women are not protected during the first trimester, although P. falciparum infections are both frequent and harmful. Methods: A cohort of nulligravidae women was followed during subsequent pregnancy...

Malaria in pregnancy threatens birth outcomes and the health of women and their newborns. This is also the case in low transmission areas, such as Colombia, where Plasmodium vivax is the dominant parasite species. Within the Colombian health system, which underwent major reforms in the '90s, malaria treatment is provided free of charge to patients. However, patients still incur costs, such as transportation and value of time lost due to the disease. We estimated such costs among 40 pregnant women with clinical malaria (30% Plasmodium falciparum, 70% Plasmodium vivax) in the municipality of Tierralta, Northern Colombia...

BACKGROUND: The Malagasy Ministry of Health aimed to achieve 80% coverage of intermittent preventive treatment of malaria among pregnant women (IPTp) in targeted districts by 2015. However, IPTp coverage rates of have remained fairly static over the past few years. METHODS: During a cross-sectional household survey, mothers of children under the age of 2 years were asked about their most recent pregnancy. The primary outcome of interest was a mother receiving two or more doses of sulfadoxine-pyrimethamine (SP) (IPTp2) during their last pregnancy, at least one of which was obtained from a health provider...

OBJECTIVES: To investigate if high-dosed folate supplements might diminish the efficacy of malaria intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) in a cohort of pregnant women in Benin, where malaria is holoendemic. METHODS: We followed 318 women during the entire pregnancy and analyzed hematological and P.falciparum indicators in the context of an intermittent preventive treatment trial in Benin. During the follow-up women received two-dose IPTp (1500/75 mg of SP per dose) at the maternity clinic, and 600 mg of albendazole, 200 mg ferrous sulfate and 5 mg folic acid per day for home treatment...

BACKGROUND: Malaria in pregnancy causes adverse birth outcomes. Intermittent preventive treatment of malaria during pregnancy with sulphadoxine-pyrimethamine (IPTp-SP) is recommended as a chemoprevention therapy. Zomba district IPTp uptake falls far below the national average. The study was conducted to assess determinants of IPTp-SP uptake during pregnancy among postpartum women in Zomba district after adoption of new IPTp-SP policy in 2014. METHODS: This was a cross-sectional survey...

BACKGROUND: The 8-aminoquinoline antimalarials, the only drugs which prevent relapse of vivax and ovale malaria (radical cure), cause dose-dependent oxidant haemolysis in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Patients with <30% and <70% of normal G6PD activity are not given standard regimens of primaquine and tafenoquine, respectively. Both drugs are currently considered contraindicated in pregnant and lactating women. METHODS: Quantitative G6PD enzyme activity data from 5198 individuals were used to estimate the proportions of heterozygous females who would be ineligible for treatment at the 30% and 70% activity thresholds, and the relationship with the severity of the deficiency...
