Summary

The goal of this observational study is to learn about the diagnostic performance of the highly sensitive rapid diagnostic test (HS-RDT) compared to an ultrasensitive qPCR for detection of falciparum malaria in pregnant women attending antenal care (ANC) in Burkina Faso. The main question it aims to answer is: • What are the sensitivity and specificity of the HS-RDT compared to ultrasensitive quantitative polymerase chain reaction (qPCR) considered as gold standard for dection of falciparum malaria in pregnant women attending ANC in Burkina Faso ? Participants will be included during their ANC visits and screened for malaria using the HS\_RDT, the conventional RDT (Co\_RDT), microscopy, and qPCR.

Detailed description

A cross-sectional study including 288 pregnant women was conducted at the Centre médical urbain (CMU) of Lafiabougou located in the periurban area of Bobo-Dioulasso the second largest city of Burkina Faso. Pregnant women attending their ANC visits at the CMU of Lafiabougou were recruited and enrolled into the study if eligible criteria were fulfilled. At enrolment, an individual structured questionnaire was administered to the selected pregnant women and their sociodemographic data (age, educational level, and profession) and history of illness was collected. In addition, obstetric history (parity, gestational age, number of ANC visits, uptake of IPTp-SP) and clinical information (body temperature, weight, height, and arm circumference) were recorded. Thereafter, a venous blood sample (5 mL) was collected to screen for malaria infection (based on HS-RDT, Co\_RDT, and thick and thin blood smears), dried blood spots (DBS) (for molecular studies), and haemoglobin concentration measurement. The remaining blood sample was stored for future studies. After enrolment, only pregnant women eligible for their first IPTp-SP dose uptake was followed up for 30 days to assess the impact of IPTp-SP on both falciparum parasitaemia and falciparum resistant strains. At the end of follow up, a venous blood sample (5 mL) was collected for thick and thin blood smears, DBS, and haemoglobin concentration measurement. The remaining blood sample was stored for future studies. All biological samples was collected and stored at ambient temperature before being transported to the Laboratory of Parasitology of Centre MURAZ and processed. The index tests included HS\_RDT (NxTek Eliminate Malaria Pf, product code 05FK140, batch No. 05LDG008B, Alere/Abbott, Republic of Korea), Co\_RDT (AdvDxTM Malaria Pf, product code 004ADFEF025KI-2, batch No. ADF77/0222, Advy Chemical, India), and light microscopy. The ultrasensitive qPCR assay targeting the multicopy conserved var gene acidic terminal sequence (varATS) (Hofmann et al. 2015) was used as gold standard.
