This study aimed at assessing placental malaria (PM) prevalence and its associated factors in a cohort of pregnant women with peripheral malaria and their offspring. METHOD: The data were collected in the framework of a clinical trial on treatments for malaria in pregnant women . Placental malaria (PM) was diagnosed by histopathological detection of parasites and/or malaria pigment on placenta biopsies taken at delivery. Factors associated with PM were assessed using logistic regression. RESULTS: Out of 745 biopsies examined, PM was diagnosed in 86.8 % of women.

A modifying effect was observed in the association of gravidity or anemia at the study start with pooled PM (presence of parasites and/or malaria pigment). In women under 30, gravidity ≤ 2 was associated with an increased prevalence of pooled PM but in women aged 30 years or more, gravidity was no more associated with pooled PM (OR 6.81, 95 % CI 3.18 - 14.60; and OR 0.52, 95 % CI 0.10 - 2.76, respectively). Anemia was associated with pooled PM in women under 30 (OR 1.96, 95 % CI 1.03 - 3.72) but not in women aged 30 years or more (OR 0.68, 95 % CI 0.31 - 1.49). Similarly, the association of gravidity with past-chronic PM depended also on age. A higher prevalence of active PM was observed in women under 30 presenting with symptomatic malaria (OR 3.79, 95 % CI 1.55 - 9.27), while there was no significant increase in the prevalence of active PM (presence of parasites only) in women with symptomatic malaria when aged 30 years or more (OR 0.42, 95 % CI 0.10 - 1.75). In women with chronic PM, the prevalence of low birth weight or prematurity was the highest (31.2 %) as compared with past PM or no PM. CONCLUSION: Despite the rapid diagnosis and efficacious treatment of peripheral infection, the prevalence of placental malaria remained high in women with P. falciparum peripheral infection in Nanoro, especially in younger women This underlines the importance of preventive measures in this specific group.},

abstract = {BACKGROUND Malaria in pregnancy remains a major health threat in sub-Saharan Africa to both expectant mothers and their unborn children. To date, there have been very few studies focused on the out of pocket costs associated with seeking treatment for malaria during pregnancy. METHODS A cross-sectional survey was undertaken in Burkina Faso and The Gambia to estimate the direct and indirect costs associated with outpatient consultations (OP) and inpatient admissions (IP). Direct costs were broken down into medical (admission fees, drug charges, and laboratory fees), and non-medical (transportation and food). Indirect costs reflected time lost due to illness. In total, 220 pregnant women in Burkina Faso and 263 in The Gambia were interviewed about their treatment seeking decisions, expenditure, time use and financial support associated with each malaria episode. RESULTS In Burkina Faso 6.7% sought treatment elsewhere before their OP visits, and 27.1% before their IP visits. This compares to 1.3% for OP and 25.92% for IP in The Gambia. Once at the facility, the average direct costs (out of pocket) were 3.91US$ for an OP visit and 15.38US$ of an IP visit in Burkina Faso, and 0.80US$ for an OP visit and 9.19US$ for an IP visit in The Gambia. Inpatient direct costs were driven by drug costs (9.27US$) and transportation costs (2.72US$) in Burkina Faso and drug costs (3.44 US$) and food costs (3.44 US$) in The Gambia. Indirect costs of IP visits, valued as the opportunity cost of time lost due to the illness, were estimated at 11.85US$ in Burkina Faso and 4.07US$ in The Gambia. The difference across the two countries was mainly due to the longer time of hospitalization in Burkina Faso compared to The Gambia. In The Gambia, the vast majority of pregnant women reported receiving financial support from family members living abroad, most commonly siblings (65%).

abstract = {BACKGROUND Intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) is an important malaria control strategy in sub-Saharan Africa. Indeed, it overcomes the risk of misdiagnosis due to low peripheral parasitemia during pregnancy by treating women with SP on predetermined schedules. However, over time, the spread of Plasmodium-resistant strains has threatened this strategy in many countries. As an alternative, the intermittent screening and treatment for pregnancy (ISTp) aims at a monthly screening of pregnant women, preferably by using very sensitive tests such as ultrasensitive rapid diagnostic tests (us-RDTs) and the treatment of positive cases with artemisinin-based combination therapy (ACT) regardless of the presence of symptoms.

BACKGROUND Intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) is an important malaria control strategy in sub-Saharan Africa. Indeed, it overcomes the risk of misdiagnosis due to low peripheral parasitemia during pregnancy by treating women with SP on predetermined schedules. However, over time, the spread of Plasmodium-resistant strains has threatened this strategy in many countries. As an alternative, the intermittent screening and treatment for pregnancy (ISTp) aims at a monthly screening of pregnant women, preferably by using very sensitive tests such as ultrasensitive rapid diagnostic tests (us-RDTs) and the treatment of positive cases with artemisinin-based combination therapy (ACT) regardless of the presence of symptoms. Unlike IPTp-SP, ISTp prevents overuse of antimalarials limiting the drug pressure on parasites, an advantage which can be potentiated by using an ACT like pyronaridine-artesunate (Pyramax®) that is not yet used in pregnant women in the field. METHODS This study aims to compare the non-inferiority of ISTp using us-RDTs and Pyramax® versus IPTp-SP on malaria in pregnancy through a randomized clinical trial performed in Kisenso, Kinshasa, the Democratic Republic of the Congo, a malaria perennial transmission area.

METHODS: A cross-sectional survey was conducted among 402

multivariate logistic regression model was used to assess the
association of malaria and STI/RTI coinfection with the

prevalence of malaria and at least one STI/RTI coinfection was
12.9% (95% confidence interval, CI: [9.8-16.7]), malaria and
bacterial vaginosis coinfection was 12.2% (95% CI:
[9.3-15.9]), malaria and chlamydial coinfection was 1.6% (95%
CI: [0.6-3.8]). No coinfection was reported for malaria and
syphilis. The individual prevalence was 17.2%, 7.2%, 0.6%,
67.7% and 73.3%, respectively, for malaria infection,
chlamydia, syphilis, bacterial vaginosis and STI/RTI

thus, 90% of women with coinfection would have been missed by
the symptoms-based diagnostic approach. In the multivariate analysis, the first pregnancy (aOR = 2.4 [95% CI: 1.2-4.7]) was
the only factor significantly associated with malaria and

Studies in children indicate that the prevalence of iron deficiency increased with malaria transmission, suggesting malaria seasonally may drive iron deficiency. This paper examines monthly seasonal infection patterns of malaria, abnormal vaginal flora, chorioamnionitis, antibiotic and antimalarial prescriptions, in relation to changes in iron biomarkers and nutritional indices in adolescents living in a rural area of Burkina Faso, in order to assess the requirement for seasonal infection control and nutrition interventions. METHODS: Data collected between April 2011 and January 2014 were available for an observational seasonal analysis, comprising scheduled visits for 1949 non-pregnant adolescents (≤19 years), (315 of whom subsequently became pregnant), enrolled in a randomised trial of periconceptional iron supplementation. Data from trial arms were combined. Body Iron Stores (BIS) were calculated using an internal regression for ferritin to allow for inflammation. At recruitment 11% had low BIS (\< 0 mg/kg). Continuous outcomes were fitted to a mixed-effects linear model with month, age and pregnancy status as fixed effect covariates and woman as a random effect. Dichotomous infection outcomes were fitted with analogous logistic regression models. RESULTS: Seasonal variation in malaria parasitaemia prevalence ranged between 18 and 70% in non-pregnant adolescents (P \< 0.001), peaking at 81% in those who became pregnant. Seasonal variation occurred in antibiotic prescription rates (0.7-1.8 prescriptions/100 weekly visits, P \< 0.001) and chorioamnionitis prevalence (range 15-68%, P = 0.026). Mucosal vaginal lactoferrin concentration was lower at the end of the wet season (range 2-22 μg/ml, P \< 0.016), when chorioamnionitis was least frequent. BIS fluctuated annually by up to 53.2% per year around the mean BIS (5.1 mg/kg(2), range 4.1-6.8 mg/kg), with low BIS (\< 0 mg/kg) of 8.7% in the dry and 9.8% in the wet seasons (P = 0.36). Median serum transferrin receptor increased during the wet season (P \< 0.001). Higher hepcidin concentration in the wet season corresponded with rising malaria prevalence and use of prescriptions, but with no change in BIS. Mean Body Mass Index and Mid-Upper-Arm-Circumference values peaked mid-dry season (both P \< 0.001). CONCLUSIONS: Our analysis supports preventive treatment of malaria among adolescents 15-19 years to decrease their disease burden, especially asymptomatic malaria. As BIS were adequate in most adolescents despite seasonal malaria, a requirement for programmatic iron supplementation was not substantiated.},

important consequence of malaria infection. In Burkina Faso, the
intensity of malaria varies according to the season, albeit the
prevalence of malaria and anaemia as well as their risk factors,
during high and low malaria transmission seasons is
underexplored at the household level. METHODS: Data of 1751
pregnant women from October 2013 to March 2014 and 1931 pregnant
women from April 2017 to June 2017 were drawn from two
cross-sectional household surveys conducted in 24 health
districts of Burkina Faso. Pregnant women were tested for
malaria in their household after consenting. Asymptomatic
carriage was defined as a positive result from malaria rapid
diagnostic tests in the absence of clinical symptoms of malaria.
Anaemia was defined as haemoglobin level less than 11 g/dL in
the first and third trimester and less than 10.5 g/dL in the
second trimester of pregnancy. RESULTS: Prevalence of
asymptomatic malaria in pregnancy was estimated at 23.9% (95%
CI 20.2-28.0) during the high transmission season
(October-November) in 2013. During the low transmission season,
it was 12.7% (95% CI 10.9-14.7) between December and March in
2013-2014 and halved (6.4%; 95% CI 5.3-7.6) between April and
June 2017. Anaemia prevalence was estimated at 59.4% (95% CI
54.8-63.8) during the high transmission season in 2013. During
the low transmission season, it was 50.6% (95% CI 47.7-53.4)
between December and March 2013-2014 and 65.0% (95% CI
62.8-67.2) between April and June, 2017. CONCLUSION: This study
revealed that the prevalence of malaria asymptomatic carriage
and anaemia among pregnant women at the community level remain
high throughout the year. Thus, more efforts are needed to
increase prevention measures such as IPTp-SP coverage in order
to reduce anaemia and contribute to preventing low birth weight
and poor pregnancy outcomes.},

cross-sectional household surveys conducted in 24 health
districts of Burkina Faso. Pregnant women were tested for
malaria in their household after consenting. Asymptomatic
carriage was defined as a positive result from malaria rapid
diagnostic tests in the absence of clinical symptoms of malaria.
Anaemia was defined as haemoglobin level less than 11 g/dL in
the first and third trimester and less than 10.5 g/dL in the
second trimester of pregnancy. RESULTS: Prevalence of
asymptomatic malaria in pregnancy was estimated at 23.9% (95%
CI 20.2-28.0) during the high transmission season
(October-November) in 2013. During the low transmission season,
it was 12.7% (95% CI 10.9-14.7) between December and March in
2013-2014 and halved (6.4%; 95% CI 5.3-7.6) between April and
June 2017. Anaemia prevalence was estimated at 59.4% (95% CI
54.8-63.8) during the high transmission season in 2013. During
the low transmission season, it was 50.6% (95% CI 47.7-53.4)
between December and March 2013-2014 and 65.0% (95% CI
62.8-67.2) between April and June, 2017. CONCLUSION: This study
revealed that the prevalence of malaria asymptomatic carriage
and anaemia among pregnant women at the community level remain
high throughout the year. Thus, more efforts are needed to
increase prevention measures such as IPTp-SP coverage in order
to reduce anaemia and contribute to preventing low birth weight
and poor pregnancy outcomes. |
