Estimated early-onset group B streptococcal neonatal disease

Area of Science:

• Neonatal Medicine
• Infectious Diseases
• Microbiology

Background:

• Estimates of early-onset group B streptococcal (EOGBS) infection incidence often rely on culture-proven cases.
• Culture-proven methods may underestimate the true burden of EOGBS due to false negatives.
• Probable EOGBS infection is defined by group B streptococci colonization plus clinical sepsis signs.

Purpose of the Study:

• To determine the combined incidence of definite and probable EOGBS infection in neonates.
• To highlight the underestimation of EOGBS disease burden by traditional methods.
• To provide evidence supporting the need for EOGBS prevention strategies.

Main Methods:

• Prospective data collection in the UK over one year.
• Inclusion of neonates requiring a septic screen within the first 72 hours of life.
• Calculation of combined incidence rates for definite and probable EOGBS infection.

Main Results:

• A combined incidence rate of 3.6 per 1000 livebirths for definite and probable EOGBS infection was observed.
• This rate indicates a significantly higher disease burden than previously suggested by culture-proven sepsis figures alone.
• The findings underscore the limitations of relying solely on culture-proven data.

Conclusions:

• The true burden of early-onset group B streptococcal infection is greater than indicated by culture-proven cases.
• The definition of probable EOGBS infection is crucial for a more accurate disease assessment.
• These findings support the implementation and enhancement of EOGBS prevention strategies in the UK.
