Trial summary

This study will follow 1000 refugee infants from birth for two years. The aim of the study is to better understand why some children develop infections caused by the bacterium Streptococcus pneumoniae whilst others merely carry this organism asymptomatically at the back of the nose (in the nasopharynx).

Study population: Maela is a densely populated camp predominantly inhabited by refugees of the Karen ethnic group. It is located in hills adjoining the Burmese border 50 km north of Mae Sot. It is the largest of the camps on the Thai-Burmese border, housing around one-third of the total refugee population. Maela has a population of approximately 43,000 people, of which 20% are females of child bearing age. Women presenting for antenatal care at SMRU's clinic will be asked to take part in the study.

Who may be able to join

  • Infants born in SMRU antenatal clinic, Maela camp
  • Written informed consent from the mother

Who cannot join

About this study

Official title: A Clinical and Microbiological Study of Acute Respiratory Infections in Refugee Infants Living on the Thai-Burmese Border

This study will follow 1000 refugee infants from birth for two years. The aim of the study is to better understand why some children develop infections caused by the bacterium Streptococcus pneumoniae whilst others merely carry this organism asymptomatically at the back of the nose (in the nasopharynx). The investigators will also define which micro-organisms cause lower respiratory tract infections (e.g., pneumonia) in this population in order to implement appropriate interventions (e.g., vaccines). Infants will be reviewed monthly and a nasopharyngeal swab will be taken. A group of 250 mother-infant pairs will be studied in greater detail, to improve our understanding of the frequency and outcomes of nasopharyngeal carriage of Streptococcus pneumoniae. Monthly nasopharyngeal swabs will be collected from mothers and infants. The investigators will measure the infant immune response to Streptococcus pneumoniae carriage or disease by taking monthly blood samples. The investigators will make an assessment of the protective effect of antibodies acquired from the mother during pregnancy by taking blood from the mother and placenta at birth. An assessment of pneumococcal carriage in mothers will also be made to determine how frequently the bacterium is transmitted between family members. All lower respiratory tract infections will be documented, and the causative micro-organisms identified.

Read the detailed description

This project's central hypothesis is that acute lower respiratory infections (ALRI) are a common and significant cause of morbidity and mortality in young children living in Maela refugee camp on the Thai-Burmese border, and that this is reflective of the general situation in the developing world. Therefore, we aim to define the incidence, aetiology, and outcome of acute lower respiratory infections in this population. This will focus on Streptococcus pneumoniae and the factors associated with colonisation and invasive disease.

Additional objectives are to:

  1. Characterise the interaction between bacterial and viral pathogens and disease.
  2. Examine the dynamics of pneumococcal nasopharyngeal carriage, including transmission of strains between infants and their mothers.
  3. Determine the effect of the non-pathogenic members of the nasopharyngeal flora on colonisation with potential pathogens.
  4. Examine the role of passively transferred maternal pneumococcal antibodies in subsequent pneumococcal colonisation and disease in the infant.
  5. Document the development of pneumococcal antibodies in the infants over time and correlate these with pneumococcal carriage and infection episodes.
  6. Determine the risk factors associated with respiratory infection.
  7. Characterise the bacteria causing invasive non-respiratory infections.
  8. Conduct surveillance for influenza and in particular avian influenza A (H5N1) infection.

Questions about this trial

What is this clinical trial studying?

An observational study of Childhood Pneumonia and Pneumococcal Carriage, run by University of Oxford at 2 sites 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 2 inclusion and 0 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 7 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

Where can I read the original study information?
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 7 May 2012.
