  • Ages 18 years and older
  • Women only

Study population: Pregant women who present at the SMRU ante natal clinics. The antenatal clinics (ANC) are based on the Thai-Burmese border, in a region where Karen people (a minority group in Burma) are the principal inhabitants.

Who may be able to join

  • Singleton viable pregnancy. If not detected at enrolment, multiple pregnancies will be excluded from the analysis.

About this study

Official title: Impact of Malaria Infection in Pregnancy on Fetal and Newborn Growth

Most of the neonatal deaths that occur worldwide every year are associated with low birth weight (LBW), caused by intrauterine growth restriction (IUGR) and/or preterm delivery. Accurate assessment of fetal growth and gestational age for timely identification and management of growth restriction are therefore public health priorities, especially in developing countries where 98% of all neonatal deaths occur. Every year, more than 50 million women become pregnant in malaria endemic regions. Malaria infection at any time during pregnancy reduces birthweight. However, little is known about the relationship between the timing of infection during pregnancy and the extent of the impact on birth weight. The mechanisms by which malaria causes LBW also remain unclear. Reduced placental blood flow, placental changes, red blood cell changes, severe anaemia and pro-inflammatory cytokines have all been implicated.

In this proposed, longitudinal, observational, minimal risk study, which will take place in SMRU antenatal clinics on the Thai-Burmese border, the effect of malaria infection during pregnancy on fetal growth will be determined. Women will be screened before 13+6 weeks of gestation and followed with regular ultrasound examinations during pregnancy. When a woman has a malaria infection an extra ultrasound scan will be done to measure growth retardation or placental blood flow changes. Bloodsamples will be taken to detect changes in red blood cell properties and putative markers of malaria infection. For this study the maximum amount of blood taken during pregnancy is 13 cc in an uninfected woman. For each malaria episode an additional 7 cc blood will be taken. After delivery a placenta and a cord sample will be taken to detect placental changes. The investigators aim to recruit four hundred pregnant women over the course of two years. This study involves minimal risk to participants as ultrasound examination is part of routine antenatal care in many countries in the world.

Questions about this trial

What is this clinical trial studying?

An observational study of Pregnant Women and Malaria, run by University of Oxford at 1 site in Thailand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ultrasound measurements (time frame: Up to birth). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00840502, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2020.
