Management of Infants Born to Group B Streptococcus Positive Mothers: Laboratory Tests vs Physical Examination

Intrapartum antibiotic prophylaxis has greatly decreased but not abolished early-onset neonatal sepsis caused by GBS. According to current recommendations, the evaluation of infants at risk for GBS sepsis should include a complete blood count (CBC), WBC differential, a blood culture (BC) and a period of observation. The usefulness of CBC and BC in the evaluation process is not firmly established.

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.

Detailed Description

After implementation of appropriate guidelines, early-onset GBS sepsis has become a low incidence disease (CDC). Recent rates are as low as 0.34 cases /1000 live births. According to CDC recommendations, the evaluation of infants at risk for GBS sepsis should include a complete blood count (CBC), WBC differential, a blood culture (BC) and a period of observation. The usefulness of CBC and BC in the evaluation process is not firmly established. There are several reviews on the predictive value of CBC and putative markers of early onset neonatal sepsis, but there seems to be no ideal laboratory test to assist the clinician in the diagnosis (Fowlie 1998, Malik 2003, Ottolini 2003). Given the continuing concerns about the reliability of laboratory tests, one may ask the question of whether physical examination might be at least as good as haematological indices. We are not aware of studies assessing the value of physical examination vs CBC, in the evaluation of asymptomatic at risk newborns.

The aim of this study was to compare two approaches in the management of infants at risk for GBS sepsis: laboratory tests (CBC, differential and BC) with observation vs clinical observation alone.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

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.
1 (first year)
Asymptomatic infants born to GBS-positive mothers or to mothers with risk factors and incomplete prophylaxis were managed according to the CDC protocol. Blood cultures and CBC were performed and the infant was observed for 48 hours. Participating hospital were free to perform any additional test, such as CRP, MiniESR, etc
2 (second year)
Asymptomatic infants born to GBS-positive mothers or to mothers with risk factors and incomplete prophylaxis were managed with clinical observation only. Clinical surveillance was based on 3 signs: 1. Skin appearance (pink, pale, mottled, cyanotic); 2. Respiratory rate (>50 or <50 breaths per minute); 3. Dyspnea (Yes / No)

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
Time Frame
Number of infants treated with antibiotics
Time Frame: Study period

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
Time Frame
Time elapsed from the onset of symptoms to the beginning of antibiotic treatment

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.
July 1, 2004

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.
June 1, 2006

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.
