abstract = {Objective: To assess the impact of an intervention package on the prescription of antibiotic and subsequently the rate of clinical recovery for non-severe acute febrile illnesses at primary health centers. Methods: Patients over 6 months of age presenting to primary health care centres with fever or history of fever within the past 7 days were randomized to receive either the intervention package constituted of point-of-care tests including COVID-19 antigen tests, a diagnostic algorithm and training and communication packages, or the standard practice. The primary outcomes were antibiotic prescriptions at Day 0 (D0) and the clinical recovery at Day 7 (D7). Secondary outcomes were non-adherence of participants and parents/caregivers to prescriptions, health workers’ non-adherence to the algorithm, and the safety of the intervention. Results: A total of 1098 patients were enrolled. 551 (50.2%) were randomized to receive the intervention versus 547 (49.8%) received standard care. 1054 (96.0%) completed follow-up and all of them recovered at D7 in both arms. The proportion of patients with antibiotic prescriptions at D0 were 33.2% (183/551) in the intervention arm versus 58.1% (318/547) under standard care, risk difference (RD) -24.9 (95% CI -30.6 to -19.2, p \< 0.001), corresponding to one more antibiotic saved every four (95% CI: 3 to 5) consultations. This reduction was also statistically significant in children from 6 to 59 months (RD -34.5; 95% CI -41.7 to -27.3; p \< 0.001), patients over 18 years (RD -35.9; 95%CI -58.5 to -13.4; p = 0.002), patients with negative malaria test (RD -46.9; 95% CI -53.9 to -39.8; p \< 0.001), those with a respiratory diagnosis (RD -48.9; 95% CI -56.9 to -41.0, p \< 0.001) and those not vaccinated against COVID-19 (-24.8% 95%CI -30.7 to -18.9, p-value: \<0.001). A significant reduction in non-adherence to prescription by patients was reported (RD -7.1; 95% CI -10.9 to -3.3; p \< 0.001). Conclusion: The intervention was associated with significant reductions of antibiotic prescriptions and non-adherence, chiefly among patients with non-malaria fever, those with respiratory symptoms and children below 5 years of age. The addition of COVID-19 testing did not have a major impact on antibiotic use at primary health centers. Trial registration: Clinitrial.gov; NCT04081051 registered on 06/09/2019.},

abstract = {Background: In malaria-endemic countries, asymptomatic carriers of plasmodium represent an important reservoir for malaria transmission. Estimating the burden at a fine scale and identifying areas at high risk of asymptomatic carriage are important to guide malaria control strategies. This study aimed to estimate the prevalence of asymptomatic carriage at the communal level in Burkina Faso, the smallest geographical entity from which a local development policy can be driven. Methods: The data used in this study came from several open sources: the 2018 Multiple Indicator Cluster Survey on Malaria and the 2019 general census of the population data and environmental. The analysis involved a total of 5489 children under 5 from the malaria survey and 293,715 children under 5 from the census. The Elbers Langjouw and Langjouw (ELL) approach is used to estimate the prevalence. This approach consists of including data from several sources (mainly census and survey data) in a statistical model to obtain predictive indicators at a sub-geographical level, which are not measured in the population census. The method achieves this by finding correlations between common census variables and survey data. Findings: The findings suggest that the spatial distribution of the prevalence of asymptomatic carriage is very heterogeneous across the communes. It varies from a minimum of 5.1% (95% CI 3.6\textendash6.5) in the commune of Bobo-Dioulasso to a maximum of 41.4% (95% CI 33.5\textendash49.4) in the commune of Djigou\'{e}. Of the 341 communes, 208 (61%) had prevalences above the national average of 20.3% (95% CI 18.8\textendash21.2). Contributions: This analysis provided commune-level estimates of the prevalence of asymptomatic carriage of plasmodium in Burkina Faso. The results of this analysis should help to improve planning of malaria control at the communal level in Burkina Faso.},

abstract = {Background: The R21/Matrix-M vaccine has demonstrated high efficacy against Plasmodium falciparum clinical malaria in children in sub-Saharan Africa. Using trial data, we aimed to estimate the public health impact and cost-effectiveness of vaccine introduction across sub-Saharan Africa. Methods: We fitted a semi-mechanistic model of the relationship between anti-circumsporozoite protein antibody titres and vaccine efficacy to data from 3 years of follow-up in the phase 2b trial of R21/Matrix-M in Nanoro, Burkina Faso. We validated the model by comparing predicted vaccine efficacy to that observed over 12\textendash18 months in the phase 3 trial. Integrating this framework within a mathematical transmission model, we estimated the cases, malaria deaths, and disability-adjusted life-years (DALYs) averted and cost-effectiveness over a 15-year time horizon across a range of transmission settings in sub-Saharan Africa. Cost-effectiveness was estimated incorporating the cost of vaccine introduction (dose, consumables, and delivery) relative to existing interventions at baseline. We report estimates at a median of 20% parasite prevalence in children aged 2\textendash10 years (PfPR2\textendash10) and ranges from 3% to 65% PfPR2\textendash10. Findings: Anti-circumsporozoite protein antibody titres were found to satisfy the criteria for a surrogate of protection for vaccine efficacy against clinical malaria. Age-based implementation of a four-dose regimen of R21/Matrix-M vaccine was estimated to avert 181 825 (range 38 815\textendash333 491) clinical cases per 100 000 fully vaccinated children in perennial settings and 202 017 (29 868\textendash405 702) clinical cases per 100 000 fully vaccinated children in seasonal settings. Similar estimates were obtained for seasonal or hybrid implementation. Under an assumed vaccine dose price of US$3, the incremental cost per clinical case averted was $7 (range 4\textendash48) in perennial settings and $6 (3\textendash63) in seasonal settings and the incremental cost per DALY averted was $34 (29\textendash139) in perennial settings and $30 (22\textendash172) in seasonal settings, with lower cost-effectiveness ratios in settings with higher PfPR2\textendash10. Interpretation: Introduction of the R21/Matrix-M malaria vaccine could have a substantial public health benefit across sub-Saharan Africa.

abstract = {Background: Although influenza viruses cause only one-fifth of severe acute respiratory infections (SARI) in Burkina Faso, the other viral causes of SARI remain poorly investigated to inform clinical and preventive decision making. Methods: Between 2016 and 2019, we prospectively enrolled inpatients meeting the World Health Organization (WHO) case definition of SARI in Burkina Faso. Results of viral etiologies among inpatients tested negative for influenza using the Fast Track Diagnostics Respiratory Kits (FTD-33) were reported. Results: Of 1541 specimens tested, at least one respiratory virus was detected in 76.1% of the 1231 specimens negative for influenza virus. Human rhinoviruses (hRVs) were the most detected pathogens (476; 38.7%), followed by human adenoviruses (hAdV) (17.1%, 210/1231), human respiratory syncytial virus (hRSV) (15.4%, 189/1231), enterovirus (EnV) (11.2%, 138/1231), human bocavirus (hBoV) (7.9%, 97/1231), parainfluenza 3 (hPIV3) (6.1%, 75/1231), human metapneumovirus (hMPV) (6.0%,74/1321), parainfluenza 4 (hPIV4) (4.1%, 51/1231), human coronavirus OC43 (hCoV-OC43) (3.4%, 42/1231), human coronavirus HKU1(hCoV-HKU1) (2.7%, 33/1231), human coronavirus NL63 (hCoV-NL63) (2.5%, 31/1231), parainfluenza 1 (hPIV1) (2.0%, 25/1231), parainfluenza 2 (hPIV2) (1.8%, 22/1231), human parechovirus (PeV) (1.1%, 14/1231), and human coronavirus 229E (hCoV-229E) (0.9%, 11/1231). Among SARI cases, infants aged 1\textendash4 years were mostly affected (50.7%; 622/1231), followed by those \<1 year of age (35.7%; 438/1231). Most detected pathogens had year-long circulation patterns, with seasonal peaks mainly observed during the cold and dry seasons. Conclusion: Several non-influenza viruses are cause of SARI in Burkina Faso. The integration of the most common pathogens into the routine influenza surveillance system might be beneficial.},

abstract = {Background: Recently, we found that a new malaria vaccine, R21/Matrix-M, had over 75% efficacy against clinical malaria with seasonal administration in a phase 2b trial in Burkina Faso. Here, we report on safety and efficacy of the vaccine in a phase 3 trial enrolling over 4800 children across four countries followed for up to 18 months at seasonal sites and 12 months at standard sites. Methods: We did a double-blind, randomised, phase 3 trial of the R21/Matrix-M malaria vaccine across five sites in four African countries with differing malaria transmission intensities and seasonality. Children (aged 5\textendash36 months) were enrolled and randomly assigned (2:1) to receive 5 μg R21 plus 50 μg Matrix-M or a control vaccine (licensed rabies vaccine [Abhayrab]). Participants, their families, investigators, laboratory teams, and the local study team were masked to treatment. Vaccines were administered as three doses, 4 weeks apart, with a booster administered 12 months after the third dose. Half of the children were recruited at two sites with seasonal malaria transmission and the remainder at standard sites with perennial malaria transmission using age-based immunisation. The primary objective was protective efficacy of R21/Matrix-M from 14 days after third vaccination to 12 months after completion of the primary series at seasonal and standard sites separately as co-primary endpoints. Vaccine efficacy against multiple malaria episodes and severe malaria, as well as safety and immunogenicity, were also assessed. This trial is registered on ClinicalTrials.gov, NCT04704830, and is ongoing. Findings: From April 26, 2021, to Jan 12, 2022, 5477 children consented to be screened, of whom 1705 were randomly assigned to control vaccine and 3434 to R21/Matrix-M; 4878 participants received the first dose of vaccine. 3103 participants in the R21/Matrix-M group and 1541 participants in the control group were included in the modified per-protocol analysis (2412 [51·9%] male and 2232 [48·1%] female). R21/Matrix-M vaccine was well tolerated, with injection site pain (301 [18·6%] of 1615 participants) and fever (754 [46·7%] of 1615 participants) as the most frequent adverse events. Number of adverse events of special interest and serious adverse events did not significantly differ between the vaccine groups. There were no treatment-related deaths. 12-month vaccine efficacy was 75% (95% CI 71\textendash79; p\<0·0001) at the seasonal sites and 68% (61\textendash74; p\<0·0001) at the standard sites for time to first clinical malaria episode. Similarly, vaccine efficacy against multiple clinical malaria episodes was 75% (71\textendash78; p\<0·0001) at the seasonal sites and 67% (59\textendash73; p\<0·0001) at standard sites. A modest reduction in vaccine efficacy was observed over the first 12 months of follow-up, of similar size at seasonal and standard sites. A rate reduction of 868 (95% CI 762\textendash974) cases per 1000 children-years at seasonal sites and 296 (231\textendash362) at standard sites occurred over 12 months. Vaccine-induced antibodies against the conserved central Asn-Ala-Asn-Pro (NANP) repeat sequence of circumsporozoite protein correlated with vaccine efficacy. Higher NANP-specific antibody titres were observed in the 5\textendash17 month age group compared with 18\textendash36 month age group, and the younger age group had the highest 12-month vaccine efficacy on time to first clinical malaria episode at seasonal (79% [95% CI 73\textendash84]; p\<0·001) and standard (75% [65\textendash83]; p\<0·001) sites. Interpretation: R21/Matrix-M was well tolerated and offered high efficacy against clinical malaria in African children. This low-cost, high-efficacy vaccine is already licensed by several African countries, and recently received a WHO policy recommendation and prequalification, offering large-scale supply to help reduce the great burden of malaria in sub-Saharan Africa.

abstract = {Background: Malaria affects millions of Cameroonian children under 5 years of age living in the North and Far North regions. These regions bear the greatest burden, particularly for children under 5 years of age. To reduce the burden of disease in these regions, Cameroon adopted the Seasonal Malaria Chemoprevention (SMC) in 2016 and has implemented it each year since its adoption. However, no previous studies have systematically assessed the effects of this intervention in Cameroon. It is important to understand its effect and whether its implementation could be improved. This study aimed to assess the effect of SMC in Cameroon during the period 2016\textendash2021 on malaria morbidity in children under 5 years of age using routine data. Methods: Data on malaria cases were extracted from the Cameroon Health Monitoring Information System (HMIS) from January 1, 2011, to December 31, 2021. Health facilities report these data monthly on a single platform, the District Health Information System version 2 (DHIS2). Thus, a controlled interrupted time-series model in a Bayesian framework was used to evaluate the effects of the SMC on malaria morbidity. Results: SMC implementation was associated with a reduction in the incidence of uncomplicated malaria cases during the high-transmission periods from 2016 to 2021. Regarding the incidence of severe malaria during the high-transmission period, a reduction was found over the period 2016\textendash2019. The highest reduction was registered during the second year of implementation in 2017:15% (95% Credible Interval, 10\textendash19) of uncomplicated malaria cases and 51% (47\textendash54) of confirmed severe malaria cases. Conclusion: The addition of SMC to the malaria intervention package in Cameroon decreased the incidence of uncomplicated and severe malaria among children under 5 years of age. Based on these findings, this study supports the wide implementation of SMC to reduce the malaria burden in Cameroon as well as the use of routine malaria data to monitor the efficiency of the strategy in a timely manner.},

abstract = {In this study, we investigated how different categories of prenatal malaria exposure (PME) influence levels of maternal antibodies in cord blood samples and the subsequent risk of malaria in early childhood in a birth cohort study (N = 661) nested within the COSMIC clinical trial (NCT01941264) in Burkina Faso. Plasmodium falciparum infections during pregnancy and infants’ clinical malaria episodes detected during the first year of life were recorded. The levels of maternal IgG and IgG1-4 to 15 P. falciparum antigens were measured in cord blood by quantitative suspension array technology. Results showed a significant variation in the magnitude of maternal antibody levels in cord blood, depending on the PME category, with past placental malaria (PM) more frequently associated with significant increases of IgG and/or subclass levels across three groups of antigens defined as pre-erythrocytic, erythrocytic, and markers of PM, as compared to those from the cord of non-exposed control infants. High levels of antibodies to certain erythrocytic antigens (i.e., IgG to EBA140 and EBA175, IgG1 to EBA175 and MSP142, and IgG3 to EBA140 and MSP5) were independent predictors of protection from clinical malaria during the first year of life. By contrast, high levels of IgG, IgG1, and IgG2 to the VAR2CSA DBL1-2 and IgG4 to DBL3-4 were significantly associated with an increased risk of clinical malaria. These findings indicate that PME categories have different effects on the levels of maternal-derived antibodies to malaria antigens in children at birth, and this might drive heterogeneity to clinical malaria susceptibility in early childhood.},

abstract = {Introduction Malaria infection during pregnancy increases the risk of low birth weight and infant mortality and should be prevented and treated. Artemisinin-based combination treatments are generally well tolerated, safe and effective; the most used being artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP). Pyronaridine-artesunate (PA) is a new artemisinin-based combination. The main objective of this study is to determine the efficacy and safety of PA versus AL or DP when administered to pregnant women with confirmed Plasmodium falciparum infection in the second or third trimester. The primary hypothesis is the pairwise non-inferiority of PA as compared with either AL or DP. Methods and analysis A phase 3, non-inferiority, randomised, open-label clinical trial to determine the safety and efficacy of AL, DP and PA in pregnant women with malaria in five sub-Saharan, malaria-endemic countries (Burkina Faso, Democratic Republic of the Congo, Mali, Mozambique and the Gambia). A total of 1875 pregnant women will be randomised to one of the treatment arms. Women will be actively monitored until Day 63 post-treatment, at delivery and 4-6 weeks after delivery, and infants' health will be checked on their first birthday. The primary endpoint is the PCR-adjusted rate of adequate clinical and parasitological response at Day 42 in the per-protocol population. Ethics and dissemination This protocol has been approved by the Ethics Committee for Health Research in Burkina Faso, the National Health Ethics Committee in the Democratic Republic of Congo, the Ethics Committee of the Faculty of Medicine and Odontostomatology/Faculty of Pharmacy in Mali, the Gambia Government/MRCG Joint Ethics Committee and the National Bioethics Committee for Health in Mozambique. Written informed consent will be obtained from each individual prior to her participation in the study. The results will be published in peer-reviewed open access journals and presented at (inter)national conferences and meetings. Trial registration number PACTR202011812241529.},

Rapid risk stratification at admission is essential for optimal medical care and improved prognosis. Whereas coma, deep breathing, and, to a lesser degree, severe anemia are established predictors of malaria-related death, the value of assessing prostration for risk stratification is less certain. Methods: Here we used a retrospective multi-center analysis comprising over 33,000 hospitalized children from four large studies, including two observational studies from the Severe Malaria in African Children network, a randomized controlled treatment study, and the phase-3-clinical RTS,S-malaria vaccine trial, to evaluate known risk factors of mortality and with a specific emphasis on the role of prostration. Results: Despite comparable age profiles of the participants, we found significant inter- and intra-study variation in the incidence of fatal malaria as well as in the derived risk ratios associated with the four risk factors: coma, deep breathing, anemia, and prostration. Despite pronounced variations, prostration was significantly associated with an increased risk of mortality (P \<0.001) and its consideration resulted in improved predictive performance, both in a multivariate model and a univariate model based on the Lambar\'{e}n\'{e} Organ Dysfunction Score. Conclusion: Prostration is an important clinical criterion to determine severe pediatric malaria with possible fatal outcomes.},

This trial aimed to evaluate the impact of an intervention package comprising diagnostic tests, a diagnostic algorithm, and a training-and-communication package on antibiotic prescriptions and clinical outcomes. Methods: Patients aged 6 months to 18 years with fever or history of fever within the past 7 days with no focus, or a suspected respiratory tract infection, arriving at 2 health facilities were randomized to either the intervention package or standard practice. The primary outcomes were the proportions of patients who recovered at day 7 (D7) and patients prescribed antibiotics at day 0. Results: Of 1718 patients randomized, 1681 (97.8%; intervention: 844; control: 837) completed follow-up: 99.5% recovered at D7 in the intervention arm versus 100% in standard practice (P =. 135). Antibiotics were prescribed to 40.6% of patients in the intervention group versus 57.5% in the control arm (risk ratio: 29.3%; 95% CI: 21.8-36.0%; risk difference [RD]: -16.8%; 95% CI: -21.7% to -12.0%; P \<. 001), which translates to 1 additional antibiotic prescription saved every 6 (95% CI: 5-8) consultations. This reduction was significant regardless of test results for malaria, but was greater in patients without malaria (RD: -46.0%; -54.7% to -37.4%; P \<. 001), those with a respiratory diagnosis (RD: -38.2%; -43.8% to -32.6%; P \<. 001), and in children 6-59 months old (RD: -20.4%; -26.0% to -14.9%; P \<. 001). Except for the period July-September, the reduction was consistent across the other quarters (P \<. 001). Conclusions: The implementation of the package can reduce inappropriate antibiotic prescription without compromising clinical outcomes.

We investigated the association between fetal sex and malaria in pregnancy in 11 pregnancy studies conducted in sub-Saharan African countries and Papua New Guinea through meta-analysis using log binomial regression fitted to a random-effects model. Malaria infection during pregnancy and delivery was assessed using light microscopy, polymerase chain reaction, and histology. Five studies were observational studies and six were randomised controlled trials. Studies varied in terms of gravidity, gestational age at antenatal enrolment and bed net use. Presence of a female fetus was associated with malaria infection at enrolment by light microscopy (risk ratio 1.14 [95% confidence interval 1.04, 1.24]; P = 0.003; n = 11,729). Fetal sex did not associate with malaria infection when other time points or diagnostic methods were used.

Protein microarrays were used to measure levels of IgG against 1000 P. falciparum antigens in 2138 infants (age 6-12 weeks) and children (age 5-17 months) from 6 African sites of the phase III trial, sampled before and at 4 longitudinal visits after vaccination. One month postvaccination, IgG responses to 17% of all probed antigens showed differences between RTS,S/AS01E and comparator vaccination groups, whereas no prevaccination differences were found. A small subset of antigens presented IgG levels reaching 4- to 8-fold increases in the RTS,S/AS01E group, comparable in magnitude to anti-CSP IgG levels (~11-fold increase). They were strongly cross-correlated and correlated with anti-CSP levels, waning similarly over time and reincreasing with the booster dose. Such an intriguing phenomenon may be due to cross-reactivity of anti-CSP antibodies with these antigens. RTS,S/AS01E vaccinees with strong off-target IgG responses had an estimated lower clinical malaria incidence after adjusting for age group, site, and postvaccination anti-CSP levels. RTS,S/AS01E-induced IgG may bind strongly not only to CSP, but also to unrelated malaria antigens, and this seems to either confer, or at least be a marker of, increased protection from clinical malaria.},

However, the scarcity of data to support decision making to reduce LBW occurrence is a major obstacle in sub-Saharan Africa. The aim of this research was to determine the prevalence and associated factors of LBW at the Yako health district in a rural area of Burkina Faso. METHODS: A cross sectional survey was conducted at four peripheral health centers among mothers and their newly delivered babies. The mothers' socio-demographic and obstetrical characteristics were collected by face-to-face interview or by review of antenatal care books. Maternal malaria was tested by standard microscopy and neonates' birth weights were documented. Multivariate logistic regression was used to determine factors associated with LBW. A p-value \< 0.05 was considered statistically significant. RESULTS: Of 600 neonates examined, the prevalence of low birth weight was 11.0%. Adjustment for socio-demographic characteristic, medical conditions, obstetrical history, malaria prevention measures by multivariate logistic regression found that being a primigravid mother (aOR = 1.8, [95% CI: 1.1-3.0]), the presence of malaria infection (aOR = 1.9, [95% CI: 1.1-3.5]), the uptake of less than three doses of sulfadoxine-pyrimethamine for the intermittent preventive treatment of malaria in pregnancy (IPTp-SP) (aOR = 2.2, [95% CI: 1.3-3.9]), the presence of maternal fever at the time of delivery (aOR = 2.8, [95% CI: 1.5-5.3]) and being a female neonate (aOR = 1.9, [95% CI: 1.1-3.3]) were independently associated with an increased risk of LBW occurrence. The number of antenatal visits performed by the mother during her pregnancy did not provide any direct protection for low birth weight. CONCLUSION: The prevalence of LBW remained high in the study area. Maternal malaria, fever and low uptake of sulfadoxine-pyrimethamine doses were significantly associated with LBW and should be adequately addressed by public health interventions.},

 of protection provided by AZ, we explored the profile of 

 protection by time since administration, using data from a 

 household-randomized, placebo-controlled trial in Burkina Faso 

 and Mali. METHODS: Between 2014 and 2016, 30 977 children aged 

 3-59 months received seasonal malaria chemoprevention (SMC) with 

 sulfadoxine-pyrimethamine plus amodiaquine and either AZ or 

 placebo monthly, on 4 occasions each year. Poisson regression 

 with gamma-distributed random effects, accounting for the 

 household randomization and within-individual clustering of 

 illness episodes, was used to compare incidence of prespecified 

 outcomes between SMC+AZ versus SMC+placebo groups in fixed time 

 strata post-treatment. The likelihood ratio test was used to 

 assess evidence for a time-treatment group interaction. RESULTS: 

 Relative to SMC+placebo, there was no evidence of protection 

 from SMC+AZ against hospital admissions and deaths. Additional 

 protection from SMC+AZ against malaria was confined to the first 

 2 weeks post-administration (protective efficacy (PE): 24.2% 

 [95% CI: 17.8%, 30.1%]). Gastroenteritis and pneumonia were 

 reduced by 29.9% [21.7; 37.3%], and 34.3% [14.9; 49.3%], 

 respectively, in the first 2 weeks postadministration. 

 Protection against nonmalaria fevers with a skin condition 

 persisted up to 28 days: PE: 46.3% [35.1; 55.6%]. CONCLUSIONS: 

 The benefits of AZ-MDA are broad-ranging but short-lived. To 

 maximize impact, timing of AZ-MDA must address the challenge of 

 targeting asynchronous morbidity and mortality peaks from 

 different causes.},

 person-years in the combination group. The hazard ratio for the 

 protective efficacy of RTS,S/AS01E as compared with 

 chemoprevention was 0.92 (95% confidence interval [CI], 0.84 to 

 1.01), which excluded the prespecified noninferiority margin of 

 1.20. The protective efficacy of the combination as compared 

 with chemoprevention alone was 62.8% (95% CI, 58.4 to 66.8) 

 against clinical malaria, 70.5% (95% CI, 41.9 to 85.0) against 

 hospital admission with severe malaria according to the World 

 Health Organization definition, and 72.9% (95% CI, 2.9 to 

 92.4) against death from malaria. The protective efficacy of the 

 combination as compared with the vaccine alone against these 

 outcomes was 59.6% (95% CI, 54.7 to 64.0), 70.6% (95% CI, 

 42.3 to 85.0), and 75.3% (95% CI, 12.5 to 93.0), respectively. 

 CONCLUSIONS: Administration of RTS,S/AS01E was noninferior to 

 chemoprevention in preventing uncomplicated malaria. The 

 combination of these interventions resulted in a substantially 

 lower incidence of uncomplicated malaria, severe malaria, and 

 death from malaria than either intervention alone. (Funded by

abstract = {BACKGROUND: Half of global child deaths occur in sub-Saharan 

 Africa. Understanding child mortality patterns and risk factors 

 will help inform interventions to reduce this heavy toll. The 

 Nanoro Health and Demographic Surveillance System (HDSS), 

 Burkina Faso was described previously, but patterns and 

 potential drivers of heterogeneity in child mortality in the 

 district had not been studied. Similar studies in other 

 districts indicated proximity to health facilities as a risk 

 factor, usually without distinction between facility types. 

 METHODS: Using Nanoro HDSS data from 2009 to 2013, we estimated 

 the association between under-5 mortality and proximity to 

 inpatient and outpatient health facilities, seasonality of 

 death, age group, and standard demographic risk factors. 

 RESULTS: Living in homes 40-60 min and \> 60 min travel time from 

 an inpatient facility was associated with 1.52 (95% CI: 

 1.13-2.06) and 1.74 (95% CI: 1.27-2.40) greater hazard of 

 under-5 mortality, respectively, than living in homes \< 20 min 

 from an inpatient facility. No such association was found for 

 outpatient facilities. The wet season (July-November) was 

 associated with 1.28 (95% CI: 1.07, 1.53) higher under-5 

 mortality than the dry season (December-June), likely reflecting 

 the malaria season. CONCLUSIONS: Our results emphasize the 

 importance of geographical proximity to health care, distinguish 

 between inpatient and outpatient facilities, and also show a 

 seasonal effect, probably driven by malaria.},

abstract = {BACKGROUND: Malaria and malnutrition remain major problems in 

 Sahel countries, especially in young children. The direct effect 

 of malnutrition on malaria remains poorly understood, and may 

 have important implications for malaria control. In this study, 

 nutritional status and the association between malnutrition and 

 subsequent incidence of symptomatic malaria were examined in 

 children in Burkina Faso and Mali who received either 

 azithromycin or placebo, alongside seasonal malaria 

 chemoprevention. METHODS: Mid-upper arm circumference (MUAC) was 

 measured in all 20,185 children who attended a screening visit 

 prior to the malaria transmission season in 2015. Prior to the 

 2016 malaria season, weight, height and MUAC were measured among 

 4149 randomly selected children. Height-for-age, weight-for-age, 

 weight-for-height, and MUAC-for-age were calculated as 

 indicators of nutritional status. Malaria incidence was measured 

 during the following rainy seasons. Multivariable random effects 

 Poisson models were created for each nutritional indicator to 

 study the effect of malnutrition on clinical malaria incidence 

 for each country. RESULTS: In both 2015 and 2016, nutritional 

 status prior to the malaria season was poor. The most prevalent 

 form of malnutrition in Burkina Faso was being underweight 

 (30.5%; 95% CI 28.6-32.6), whereas in Mali stunting was most 

 prevalent (27.5%; 95% CI 25.6-29.5). In 2016, clinical malaria 

 incidence was 675 per 1000 person-years (95% CI 613-744) in 

 Burkina Faso, and 1245 per 1000 person-years (95% CI 1152-1347) 

 in Mali. There was some evidence that severe stunting was 

 associated with lower incidence of malaria in Mali (RR 0.81; 95% CI 0.64-1.02; p = 0.08), but this association was not seen 

 in Burkina Faso. Being moderately underweight tended to be 

 associated with higher incidence of clinical malaria in Burkina Faso (RR 1.27; 95% CI 0.98-1.64; p = 0.07), while this was the 

 case in Mali for moderate wasting (RR 1.27; 95% CI 0.98-1.64; p = 0.07). However, these associations were not observed in 

 severely affected children, nor consistent between countries. 

 MUAC-for-age was not associated with malaria risk. CONCLUSIONS: 

 Both malnutrition and malaria were common in the study areas, 

 high despite high coverage of seasonal malaria chemoprevention 

 and long-lasting insecticidal nets. However, no strong or 

 consistent evidence was found for an association between any of 

 the nutritional indicators and the subsequent incidence of 

 clinical malaria.},

 risk for bacterial bloodstream infections. We hypothesized that 

 asymptomatic malaria parasitemia increases susceptibility for 

 bacterial infections through an effect on the innate immune 

 system. We measured circulating cytokine levels and ex-vivo 

 cytokine production capacity in asymptomatic malaria and 

 compared with controls. Methods: Data were collected from 

 asymptomatic participants \<5 years old with and without positive 

 malaria microscopy, as well as from hospitalized patients \<5 

 years old with clinical malaria, bacteremia, or 

 malaria/bacteremia co-infections in a malaria endemic region of 

 Burkina Faso. Circulating cytokines (TNF-$alpha$, IFN-$gamma$, 

 IL-6, IL-10) were measured using multiplex assays. Whole blood 

 from asymptomatic participants with and without positive malaria 

 microscopy were ex-vivo stimulated with S. aureus, E. coli LPS 

 and Salmonella Typhimurium; cytokine concentrations 

 (TNF-$alpha$, IFN-$gamma$, IL-1$beta$, IL-6, IL-10) were 

 measured on supernatants using ELISA. Results: Included were children with clinical malaria (n=118), bacteremia (n=22), malaria and bacteremia co-infection (n=9), asymptomatic malaria (n=125), and asymptomatic controls (n=237). Children with either 

 clinical or asymptomatic malaria had higher plasma cytokine 

 concentrations than controls. Cytokine concentrations correlated 

 positively with malaria parasite density with the strongest correlation for IL-10 in both asymptomatic (r=0.63) and clinical malaria (r=0.53). Patients with bacteremia had lower circulating 

 IL-10, TNF-$alpha$ and IFN-$gamma$ and higher IL-6 

 concentrations, compared to clinical malaria. Ex-vivo whole 

 blood cytokine production to LPS and S. aureus was significantly 

 lower in asymptomatic malaria compared to controls. Whole blood 

 IFN-$gamma$ and IL-10 production in response to Salmonella was 

 also lower in asymptomatic malaria. Interpretation: In children 

 with asymptomatic malaria, cytokine responses upon ex-vivo 

 bacterial stimulation are downregulated. Further studies are 

 needed to explore if the suggested impaired innate immune 

 response to bacterial pathogens also translates into impaired 

 control of pathogens such as Salmonella spp.},

abstract = {BACKGROUND: Malaria and malnutrition represent major public 

 health concerns worldwide especially in Sub-Sahara Africa. 

 Despite implementation of seasonal malaria chemoprophylaxis 

 (SMC), an intervention aimed at reducing malaria incidence among 

 children aged 3-59 months, the burden of malaria and associated 

 mortality among children below age 5 years remains high in 

 Burkina Faso. Malnutrition, in particular micronutrient 

 deficiency, appears to be one of the potential factors that can 

 negatively affect the effectiveness of SMC. Treating 

 micronutrient deficiencies is known to reduce the incidence of 

 malaria in highly prevalent malaria zone such as rural settings. 

 Therefore, we hypothesized that a combined strategy of SMC 

 together with a daily oral nutrients supplement will enhance the 

 immune response and decrease the incidence of malaria and 

 malnutrition among children under SMC coverage. METHODS: 

 Children (6-59 months) under SMC coverage receiving vitamin A 

 supplementation will be randomly assigned to one of the three 

 study arms (a) SMC + vitamin A alone, (b) SMC + vitamin A + 

 zinc, or (c) SMC + vitamin A + Plumpy'Doz™ using 1:1:1 

 allocation ratio. After each SMC monthly distribution, children 

 will be visited at home to confirm drug administration and 

 followed-up for 1 year. Anthropometric indicators will be 

 recorded at each visit and blood samples will be collected for 

 microscopy slides, haemoglobin measurement, and spotted onto 

 filter paper for further PCR analyses. The primary outcome 

 measure is the incidence of malaria in each arm. Secondary 

 outcome measures will include mid-upper arm circumference and 

 weight gain from baseline measurements, coverage and compliance 

 to SMC, occurrence of adverse events (AEs), and prevalence of 

 molecular markers of antimalarial resistance comprising Pfcrt, 

 Pfmdr1, Pfdhfr, and Pfdhps. DISCUSSION: This study will 

 demonstrate an integrated strategy of malaria and malnutrition 

 programmes in order to mutualize resources for best impact. By 

 relying on existing strategies, the policy implementation of 

 this joint intervention will be scalable at country and regional 

 levels. TRIAL REGISTRATION: ClinicalTrials.gov NCT04238845 .

abstract = {BACKGROUND: Socioeconomic inequalities between and within countries lead to disparities in the use of health services. These disparities could lead to child  mortality in children under 5 years by depriving them of healthcare. Therefore,  initiatives to remove healthcare fees such as the Free Healthcare Initiative (FHCI)  adopted in Sierra Leone can contribute to reducing these inequities in  healthcare-seeking for children. This study aimed to assess the socioeconomic  inequalities in healthcare-seeking for children under 5 years of age before and  after the implementation of the FHCI. METHODS: Data were included on 1207, 2815,  1633, and 1476 children under 5 years of age with fever from the 2008, 2013, 2016,  and 2019 nationwide surveys, respectively. Concentration curves were drawn for the  period before (2008) and after (2013-2019) the implementation of the FHCI to assess  socioeconomic inequalities in healthcare-seeking. Finally, Erreyger's corrected  concentration indices were calculated to understand the magnitude of these  inequalities. RESULTS: Before the implementation of the FHCI, there were  inequalities in healthcare-seeking for children under five (Erreyger's corrected  concentration index (CI) = 0.168, standard error (SE) = 0.049; p \< 0.001) in favor  of the wealthy households. These inequalities decreased after the implementation of  the FHCI (CI = 0.061, SE = 0.033; p = 0.06 in 2013, CI = 0.039, SE = 0.04; p = 0.32  in 2016, and CI = - 0.0005, SE = 0.362; p = 0.98 in 2019). Furthermore, before the  implementation of the FHCI, a significant pro-rich inequality in the districts of  Kenema (CI = 0.117, SE = 0.168, p = 0.021), Kono (CI = 0.175, SE = 0.078, p = 0.028)  and Western Area Urban (CI = 0.070, SE = 0.032, p = 0.031) has been observed. After  the implementation of the FHCI in 2019, these disparities were reduced, 11 of the 14  districts had a CI around the value of equality, and only in 2 districts the  pro-rich inequality were significant (Western Area Urban (CI = 0.035, SE = 0.016,  p = 0.039) and Western Area Rural (CI = 0.066, SE = 0.030, p = 0.027)). CONCLUSION:  The results of this study demonstrated that socio-economic inequalities in  healthcare-seeking for children have been considerably reduced after the FHCI in  Sierra Leone. To further reduce these inequalities, policy actions can focus on the  increase of availability of health services in the districts where the  healthcare-seeking remained pro-rich.},

 of a single-dose combination of artefenomel (800 mg) plus 

 ferroquine (400/600/900/1200 mg doses) for the treatment of 

 uncomplicated P. falciparum malaria were evaluated in Africa 

 (focusing on children $\leq$ 5 years) and Asia. METHODS: The 

 study was a randomized, double-blind, single-dose, multi-arm 

 clinical trial in patients aged \> 6 months to 5 years and 20 

 Asian patients. None of the treatment arms met the target 

 efficacy criterion for PCR-adjusted ACPR at Day 28 (lower limit 

 of 95% confidence interval [CI] \> 90%). PCR-adjusted ACPR at 

 Day 28 [95% CI] in the PP Set ranged from 78.4% [64.7; 88.7%] 

 to 91.7% [81.6; 97.2%] for the 400 mg to 1200 mg ferroquine 

 dose. Efficacy rates were low in Vietnamese patients, ranging 

 from 20 to 40%. A clear relationship was found between drug 

 exposure (artefenomel and ferroquine concentrations at Day 7) 

 and efficacy (primary endpoint), with higher concentrations of 

 both drugs resulting in higher efficacy. Six distinct kelch-13 

 mutations were detected in parasite isolates from 10/272 African 

 patients (with 2 mutations known to be associated with 

 artemisinin resistance) and 18/20 Asian patients (all C580Y

abstract = {BACKGROUND: Stalled progress in controlling Plasmodium 

 falciparum malaria highlights the need for an effective and 

 deployable vaccine. RTS,S/AS01, the most effective malaria 

 vaccine candidate to date, demonstrated 56% efficacy over 12 

 months in African children. We therefore assessed a new 

 candidate vaccine for safety and efficacy. METHODS: In this 

 double-blind, randomised, controlled, phase 2b trial, the 

 low-dose circumsporozoite protein-based vaccine R21, with two 

 different doses of adjuvant Matrix-M (MM), was given to children 

 aged 5-17 months in Nanoro, Burkina Faso-a highly seasonal 

 malaria transmission setting. Three vaccinations were 

 administered at 4-week intervals before the malaria season, with 

 a fourth dose 1 year later. All vaccines were administered 

 intramuscularly into the thigh. Group 1 received 5 $mu$g R21 

 plus 25 $mu$g MM, group 2 received 5 $mu$g R21 plus 50 $mu$g 

 MM, and group 3, the control group, received rabies 

 vaccinations. Children were randomly assigned (1:1:1) to groups 

 1-3. An independent statistician generated a random allocation 

 list, using block randomisation with variable block sizes, which 

 was used to assign participants. Participants, their families, 

 and the local study team were all masked to group allocation. 

 Only the pharmacists preparing the vaccine were unmasked to 

 group allocation. Vaccine safety, immunogenicity, and efficacy 

 were evaluated over 1 year. The primary objective assessed 

 protective efficacy of R21 plus MM (R21/MM) from 14 days after 

 the third vaccination to 6 months. Primary analyses of vaccine 

 efficacy were based on a modified intention-to-treat population, 

 which included all participants who received three vaccinations, 

 allowing for inclusion of participants who received the wrong 

 vaccine at any timepoint. This trial is registered with 

 ClinicalTrials.gov, NCT03896724. FINDINGS: From May 7 to June 

 13, 2019, 498 children aged 5-17 months were screened, and 48 

 were excluded. 450 children were enrolled and received at least 

 one vaccination. 150 children were allocated to group 1, 150 

 children were allocated to group 2, and 150 children were 

 allocated to group 3. The final vaccination of the primary 

 series was administered on Aug 7, 2019. R21/MM had a favourable 

 safety profile and was well tolerated. The majority of adverse 

 events were mild, with the most common event being fever. None 

 of the seven serious adverse events were attributed to the 

 vaccine. At the 6-month primary efficacy analysis, 43 (29%) of 

 146 participants in group 1, 38 (26%) of 146 participants in 

 group 2, and 105 (71%) of 147 participants in group 3 developed 

 clinical malaria. Vaccine efficacy was 74% (95% CI 63-82) in 

 group 1 and 77% (67-84) in group 2 at 6 months. At 1 year, 

 vaccine efficacy remained high, at 77% (67-84) in group 1. 

 Participants vaccinated with R21/MM showed high titres of 

 malaria-specific anti-Asn-Ala-Asn-Pro (NANP) antibodies 28 days 

 after the third vaccination, which were almost doubled with the 

 higher adjuvant dose. Titres waned but were boosted to levels 

 similar to peak titres after the primary series of vaccinations 

 after a fourth dose administered 1 year later. INTERPRETATION: 

 R21/MM appears safe and very immunogenic in African children, 

 and shows promising high-level efficacy. FUNDING: The European

abstract = {This study in Burkina Faso investigated whether offspring of young mothers who had received weekly periconceptional iron supplementation in a randomised controlled  trial were at increased risk of malaria. A child safety survey was undertaken in the  peak month of malaria transmission towards the end of the trial to assess child iron  biomarkers, nutritional status, anaemia and malaria outcomes. Antenatal iron  biomarkers, preterm birth, fetal growth restriction and placental pathology for  malaria and chorioamnionitis were assessed. Data were available for 180 babies  surviving to the time of the survey when their median age was 9 months. Prevalence  of maternal iron deficiency in the last trimester based on low body iron stores was  16%. Prevalence of active placental malaria infection was 24.8%, past infection 59%  and chorioamnionitis 55.6%. Babies of iron supplemented women had lower median  gestational age. Four out of five children ≥ 6 months were iron deficient, and 98%  were anaemic. At 4 months malaria prevalence was 45%. Child iron biomarkers, anaemia  and malaria outcomes did not differ by trial arm. Factors associated with childhood  parasitaemia were third trimester C-reactive protein level (OR 2.1; 95% CI 1.1-3.9),  active placental malaria (OR 5.8; 1.0-32.5, P = 0.042) and child body iron stores  (OR 1.13; 1.04-1.23, P = 0.002). Chorioamnionitis was associated with reduced risk  of child parasitaemia (OR 0.4; 0.1-1.0, P = 0.038). Periconceptional iron  supplementation of young women did not alter body iron stores of their children.  Higher child body iron stores and placental malaria increased risk of childhood  parasitaemia.},

abstract = {INTRODUCTION: acute diarrhea in children under five years is a public health problem in developing countries and particularly in malaria-endemic areas where both  diseases co-exist. The present study examined the etiology of childhood diarrhea and  its comorbidity with malaria in a rural area of Burkina Faso. 

METHODS: conventional  culture techniques, direct stools examination, and viruses´ detection by rapid tests  were performed on the fresh stools and microscopy was used to diagnose malaria. Some  risk factors were also assessed. RESULTS: on a total of 191 samples collected, at  least one pathogen was identified in 89 cases (46.6%). The proportions of pathogens  found on the 89 positive stool samples were parasites 51.69% (46 cases), viruses  39.33% (35 cases), and bacteria 14.61% (13 cases), respectively. The relationship  between malaria and infectious diarrhea was significant in viral and parasites  causes (p=0.005 and 0.043 respectively). Fever, vomiting and abdominal pain were the  major symptoms associated with diarrhea, with 71.51%, 31.72% and 23.66%  respectively. The highest viral diarrhea prevalence was reported during the dry  season (OR=5.29, 95% CI: 1.74 - 16.07, p=0.001) while parasite diarrhea was more  encountered during the rainy season (OR=0.41, 95% CI: 0.33 - 0.87, p=0.011).  CONCLUSION: Giardia spp and rotavirus were the leading cause of acute diarrhea in  Nanoro, Burkina Faso with a predominance of rotavirus in children less than 2 years.  Parasite and viral diarrhea were the most pathogens associated with malaria.  However, the high rate of negative stool samples suggests the need to determine  other enteric microorganisms.},

abstract = {BACKGROUND: New hemocytometric parameters can be used to 

 differentiate causes of acute febrile illness (AFI). We 

 evaluated a software algorithm-Infection Manager System 

 (IMS)-which uses hemocytometric data generated by Sysmex 

 hematology analyzers, for its accuracy to detect bacteremia in 

 AFI patients with and without malaria in Burkina Faso. Secondary 

 aims included comparing the accuracy of IMS with C-reactive 

 protein (CRP) and procalcitonin (PCT). METHODS: In a prospective 

 observational study, patients of $geq$ three-month-old (range 3 

 months- 90 years) presenting with AFI were enrolled. IMS, blood 

 culture and malaria diagnostics were done upon inclusion and 

 additional diagnostics on clinical indication. CRP, PCT, viral 

 multiplex PCR on nasopharyngeal swabs and bacterial- and malaria 

 PCR were batch-tested retrospectively. Diagnostic classification 

 was done retrospectively using all available data except IMS, 

 CRP and PCT results. FINDINGS: A diagnosis was affirmed in 549/914 (60.1%) patients and included malaria (n = 191) bacteremia (n = 69), viral infections (n = 145), and malaria-bacteremia co-infections (n = 47). The overall 

 sensitivity, specificity, and negative predictive value (NPV) of 

 IMS for detection of bacteremia in patients of $geq$ 5 years 

 were 97.0% (95% CI: 89.8-99.6), 68.2% (95% CI: 55.6-79.1) 

 and 95.7% (95% CI: 85.5-99.5) respectively, compared to 93.9% 

 (95% CI: 85.2-98.3), 39.4% (95% CI: 27.6-52.2), and 86.7% 

 (95% CI: 69.3-96.2) for CRP at $geq$20mg/L. The sensitivity, 

 specificity and NPV of PCT at 0.5 ng/ml were lower at 

 respectively 72.7% (95% CI: 60.4-83.0), 50.0% (95% CI: 

 37.4-62.6) and 64.7% (95% CI: 50.1-77.6) The diagnostic 

 accuracy of IMS was lower among malaria cases and patients \<5 

 years but remained equal to- or higher than the accuracy of CRP. 

 INTERPRETATION: IMS is a new diagnostic tool to differentiate 

 causes of AFI. Its high NPV for bacteremia has the potential to 

 improve antibiotic dispensing practices in healthcare facilities 

 with hematology analyzers. Future studies are needed to evaluate 

 whether IMS, combined with malaria diagnostics, may be used to 

 rationalize antimicrobial prescription in malaria endemic areas.

abstract = {BACKGROUND: Genetic polymorphisms in the human immune system 

 modulate susceptibility to malaria. However, there is a paucity 

 of data on the contribution of immunogenetic variants to malaria 

 susceptibility in infants, who present differential biological 

 features related to the immaturity of their adaptive immune 

 system, the protective effect of maternal antibodies and fetal 

 haemoglobin. This study investigated the association between 

 genetic variation in innate immune response genes and malaria 

 susceptibility during the first year of life in 656 infants from 

 a birth cohort survey performed in Nanoro, Burkina Faso. 

 METHODS: Seventeen single nucleotide polymorphisms (SNPs) in 11 

 genes of the immune system previously associated with different 

 malaria phenotypes were genotyped using TaqMan allelic 

 hybridization assays in a Fluidigm platform. Plasmodium 

 falciparum infection and clinical disease were documented by 

 active and passive case detection. Case-control association 

 analyses for both alleles and genotypes were carried out using 

 univariate and multivariate logistic regression. For cytokines 

 showing significant SNP associations in multivariate analyses, 

 cord blood supernatant concentrations were measured by 

 quantitative suspension array technology (Luminex). RESULTS: 

 Genetic variants in IL-1$beta$ (rs1143634) and 

 Fc$gamma$RIIA/CD32 (rs1801274)-both in allelic, dominant and 

 co-dominant models-were significantly associated with protection 

 from both P. falciparum infection and clinical malaria. 

 Furthermore, heterozygote individuals with rs1801274 SNP in 

 Fc$gamma$RIIA/CD32 showed higher IL-1RA levels compared to wild-type homozygotes (P = 0.024), a cytokine whose production 

 is promoted by the binding of IgG immune complexes to Fc$gamma$ 

 receptors on effector immune cells. CONCLUSIONS: These findings 

 indicate that genetic polymorphisms in genes driving innate 

 immune responses are associated to malaria susceptibility during 

 the first year of life, possibly by modulating production of 

 inflammatory mediators.},
