Study to Identify and Characterize Bacteria Causing Acute Otitis Media in South African Children

May 20, 2010 updated by: GlaxoSmithKline

Identification and Characterization of the Bacteria Causing Acute Otitis Media (AOM) Episodes in HIV-positive and HIV-negative Children in South Africa

The purpose of this study is to identify and characterize the bacteria causing acute otitis media episode in HIV-positive and HIV-negative children (>=3 months to <5 years) in South Africa. Middle ear fluid sampling either by tympanocentesis or by careful sampling of spontaneous otorrhoea will be done; nasopharyngeal aspirate and urine sample will also be collected from the subjects.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

3 months to 5 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Children aged >= 3 months and < 5 years seeking healthcare for the treatment of acute otitis media.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
HIV-negative Group
This group is sub-divided into two sub-groups. One sub-group includes HIV-negative/ presumed negative subjects with a new episode of acute otitis media who have not yet received antibiotic therapy for the episode and the other sub-group includes HIV-negative/ presumed negative subjects with treatment failure who have had a diagnosis of acute otitis media and showed no clinical improvement within 48-72 hours of antibiotic treatment.
Procedure: Middle ear fluid, nasopharyngeal aspirate and urine sample.
Middle ear fluid, nasopharyngeal aspirate and urine sample collection.
HIV-positive Group
This group is sub-divided into two sub-groups. One sub-group includes HIV-positive subjects with a new episode of acute otitis media who have not yet received antibiotic therapy for the episode and the other sub-group includes HIV-positive subjects with treatment failure who have had a diagnosis of acute otitis media and showed no clinical improvement within 48-72 hours of antibiotic treatment.
Procedure: Middle ear fluid, nasopharyngeal aspirate and urine sample.
Middle ear fluid, nasopharyngeal aspirate and urine sample collection.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Occurrence of bacterial pathogens isolated from middle ear fluid samples in HIV-positive and HIV-negative subjects.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Occurrence of bacterial serotypes.
Antimicrobial susceptibility of different bacteria isolated from middle ear fluid samples as assessed by standard microbiological techniques.
Occurrence of treatment failure of acute otitis media and of recurrent acute otitis media.
Occurrence of spontaneous otorrhoea.
Occurrence of bacteria in acute otitis media cases with treatment failure and in new acute otitis media cases without treatment therapy.
Occurrence of bacteria in acute otitis media cases vaccinated with a pneumococcal vaccine.
Frequency of concurrent respiratory viral infection coinciding with the episode of acute otitis media.
The comparison of above endpoints in HIV-positive and HIV-negative subjects.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
