Therapeutic Role of Hydroxyurea in Paediatric Hydroxyurea Pertussis: A systematic review

Area of Science:

• Pediatric Critical Care Medicine
• Pharmacology
• Infectious Diseases

Background:

• Pertussis, particularly in infants, can lead to severe complications including high white blood cell counts (leukocytosis).
• Current management for severe leukocytosis in pediatric critical care may involve invasive leukoreductive procedures.
• There is a need for effective and less invasive therapeutic options for managing leukoreduction in pediatric critical pertussis.

Purpose of the Study:

• To systematically review the existing evidence on the use of hydroxyurea for leukoreduction in pediatric critical pertussis.
• To assess the potential efficacy and safety of hydroxyurea as an adjunctive treatment in this patient population.

Main Methods:

• Systematic review of published literature, including case reports and case series.
• Analysis of reported outcomes related to leukocyte reduction and patient survival.
• Evaluation of safety monitoring and follow-up data where available.

Main Results:

• Hydroxyurea was associated with leukocyte reduction in reported cases of pediatric critical pertussis.
• Short-term survival was observed in patients treated with hydroxyurea.
• The drug may offer a less invasive alternative to traditional leukoreductive procedures, particularly in resource-limited settings.

Conclusions:

• Hydroxyurea presents a potentially promising pharmacologic option for leukoreduction in pediatric critical pertussis.
• The current evidence is limited to low-certainty data from uncontrolled studies, necessitating caution.
• Further rigorous, multicenter studies and randomized controlled trials are essential to validate hydroxyurea's efficacy and safety profile.
