Pertussis: should we improve intensive care management or vaccination strategies?

Area of Science:

• Pediatrics
• Infectious Diseases
• Critical Care Medicine

Background:

• Bordetella pertussis causes pertussis (whooping cough), a vaccine-preventable illness with significant resurgence and mortality worldwide.
• Despite vaccination efforts for various age groups, severe cases, particularly in infants, pose critical care challenges.
• Current management strategies for infant pertussis include mechanical ventilation and extracorporeal support, with leukodepletion emerging as a novel therapeutic option.

Discussion:

• This paper evaluates the use of rapid leukodepletion in infants experiencing extreme leukocytosis due to pertussis.
• The UK investigators' experience demonstrated a swift reduction in leukocyte counts following this intervention.
• The findings suggest leukodepletion is a viable strategy for managing severe pertussis with high white blood cell counts.

Key Insights:

• Rapid leukodepletion significantly decreases leukocyte counts in infants with severe pertussis and extreme leukocytosis.
• This intervention offers a potential adjunctive therapy for critically ill infants.
• Early consideration of leukodepletion may improve outcomes in severe pertussis cases.

Outlook:

• Further research is warranted to establish standardized protocols for rapid leukodepletion in pediatric pertussis.
• Investigating the long-term efficacy and safety of leukodepletion in this population is crucial.
• This approach could become a standard component of critical care for severe infant pertussis.
