BACKGROUND: The high burden of malaria and limited funding means there is a necessity to maximize the allocative efficiency of malaria control programmes. Quantitative tools are urgently needed to guide budget allocation decisions. METHODS: A geospatial epidemic model was coupled with costing data and an optimization algorithm to estimate the optimal allocation of budgeted and projected funds across all malaria intervention approaches. Interventions included long-lasting insecticide-treated nets (LLINs), indoor residual spraying (IRS), intermittent presumptive treatment during pregnancy (IPTp), seasonal mass chemoprevention in children (SMC), larval source management (LSM), mass drug administration (MDA), and behavioural change communication (BCC)...

Pregnancy-associated malaria (PAM) poses a threat to both the mother and fetus, increasing the risk of severe maternal anemia, fetal growth restriction and low birth weight infants. Two vaccines are currently in development to protect women from Plasmodium falciparum in pregnancy. Both vaccine constructs target the ID1-DBL2Xb domain of VAR2CSA, a protein expressed on the surface of infected erythrocytes (IEs) that mediates parasite sequestration in the placenta. Although development of an effective vaccine may be hampered by ID1-DBL2Xb polymorphisms expressed by field isolates, a recent study showed that genetic variation of this domain in South American parasite populations is much lower than in other geographical locations...

Placental malaria, characterized by sequestration of Plasmodium falciparum in the maternal placental blood space and associated inflammatory damage, contributes to poor birth outcomes and ~200,000 infant deaths annually. Specific mechanisms that contribute to placental damage and dysfunction during malaria are not completely understood. To investigate a potential role for oxidative stress, antioxidant genes and markers for oxidative damage were assessed by quantitative PCR and immunohistochemistry in Plasmodium chabaudi AS-infected pregnant mice...

BACKGROUND: Ethiopia is a developing country where intestinal helminthic infections are major public health problems. The burden of intestinal parasites, particularly the soil-transmitted helminths (STHs), is often very high in school children and pregnant women. Anemia, associated with STH, is a major factor in women's health, especially during pregnancy; it is an important contributor to maternal mortality. The aim of this study was to determine the prevalence of intestinal helminthic infection and anemia among pregnant women attending ANC in East Wollega Zone, Ethiopia...

OBJECTIVES: Malaria in pregnancy (MiP) contributes to fetal undernutrition and adverse birth outcomes, and may constitute a developmental origin of metabolic diseases in the offspring. In a Ghanaian birth cohort, we examined the relationships between MiP-exposure and metabolic traits in adolescence. METHODS: MiP at delivery was assessed in 155 mother-child pairs. Among the now teenaged children (mean age, 14.8 years; 53% male), we measured fasting plasma glucose (FPG), body mass index (BMI), and systolic and diastolic blood pressure (BP)...

BACKGROUND: Maternal antibodies may play a role in protecting newborns against malaria disease. Plasmodium falciparum parasite surface antigens are diverse and protection from infection requires allele-specific immunity. Although malaria-specific antibodies have been shown to cross the placenta, the extent to which antibodies that respond to the full repertoire of diverse antigens are transferred from the mother to the infant has not been explored. Understanding the breadth of maternal antibody responses and to what extent these antibodies are transferred to the child can inform vaccine design and evaluation...

BACKGROUND: Malaria in pregnancy leads to low birth weight, premature birth, anaemia, and maternal and neonatal mortality. Use of insecticide-treated nets (ITNs) during pregnancy is one of the proven interventions to reduce the malaria burden. However, Ghana has not achieved its target for ITN use among pregnant women. METHODS: A qualitative study was conducted in seven communities purposively selected from the middle belt of Ghana. Participants who had delivered in the six months prior to this study were selected...

Malaria-associate pregnancy has a significant impact on infant morbidity and mortality. The detrimental effects of malaria infection during pregnancy have been shown to correlate with immune activation in the placental tissue. Herein we sought to evaluate the effect of Toll-like receptors (TLRs) activation on placental malaria (PM) development by using the Plasmodium berghei NK65(GFP) infection model. We observed that activation of the innate immune system by parasites leads to PM due to local inflammation...

Pregnancy associated malaria (PAM) causes adverse pregnancy and birth outcomes owing to Plasmodium falciparum accumulation in the placenta. Placental accumulation is mediated by P. falciparum protein VAR2CSA, a leading PAM-specific vaccine target. The extent of its antigen diversity and impact on clinical outcomes remain poorly understood. Through amplicon deep-sequencing placental malaria samples from women in Malawi and Benin, we assessed sequence diversity of VAR2CSA's ID1-DBL2x region, containing putative vaccine targets and estimated associations of specific clades with adverse birth outcomes...

BACKGROUND: Malaria in pregnancy poses a great risk to both mother and fetus. In Ghana, malaria accounts for 3.4% of deaths and 16.8% of all hospital admissions in pregnant women. In 2014, Ghana updated her policy on intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) to reflect the updated policy of the WHO. This study determined the level of uptake of sulfadoxine pyrimethamine (SP) to serve as baseline for monitoring progress and also reviewed stock levels of SP, a key factor in the programme implementation...

BACKGROUND: Four studies previously indicated that the effect of malaria infection during pregnancy on the risk of low birthweight (LBW; <2,500 g) may depend upon maternal nutritional status. We investigated this dependence further using a large, diverse study population. METHODS AND FINDINGS: We evaluated the interaction between maternal malaria infection and maternal anthropometric status on the risk of LBW using pooled data from 14,633 pregnancies from 13 studies (6 cohort studies and 7 randomized controlled trials) conducted in Africa and the Western Pacific from 1996-2015...

REVIEW
Lalita Sharma, Geeta Shukla
Malaria in pregnancy poses a great health risk to mother and her fetus and results into complications, such as abortion, still birth, intra uterine growth retardation, and low birth weight. The heavy infiltration of Plasmodium falciparum-infected RBCs in the intervillous spaces of placenta seems to be responsible for all the complications observed. Infected RBCs in the placenta cause an inflammatory environment with increase in inflammatory cells and cytokines which is deleterious to the placenta. Increased inflammatory responses in the infected placenta result into oxidative stress that in turn causes oxidative stress-induced placental cell death...

Resistance to standard antimalarials has led to the need for newer options. Artemisinin-based combination therapies (ACTs), which require a tedious three-day treatment schedule, have been introduced for the treatment of drug-resistant malaria. Of late, the new generation artemisinin-naphthoquine (ANQ) combination has been developed, which requires a single dose treatment. Artemisinin initiates the action through the cleavage of the endoperoxide bridge while naphtoquine maintains the process by getting concentrated in the digestive vacuole of the parasite...
