Insights
Children with cerebral palsy (CP) admitted to the pediatric intensive care unit (PICU) frequently carry abnormal and antibiotic-resistant bacteria. These children experience higher infection rates and mortality, underscoring the need for targeted interventions.
Area of Science:
- Pediatric Intensive Care
- Infectious Diseases
- Microbiology
Background:
- Severe and chronic illnesses can alter oropharyngeal and gut bacterial flora.
- Limited data exists on the bacterial flora of children with chronic neurologic impairment.
Purpose of the Study:
- To assess the carriage of abnormal bacterial flora and antibiotic-resistant bacteria in children with cerebral palsy (CP) admitted to the pediatric intensive care unit (PICU).
- To evaluate infection rates and mortality in this patient population.
Main Methods:
- Prospective observational single-center cohort study.
- Included children with CP ventilated for >= 4 days in the PICU.
- Surveillance and diagnostic samples of throat and rectum were collected.
Main Results:
- 89% of children with CP carried abnormal bacterial flora/potential pathogens (e.g., Pseudomonas, Klebsiella).
- 47% carried antibiotic-resistant bacteria.
- 35 children developed 86 infections; infection rates were significantly higher than in children without CP.
Conclusions:
- Children with moderate to severe chronic neurologic impairment admitted to the PICU have a high incidence of abnormal bacteria, antibiotic-resistant bacteria, and infections.
- These findings highlight significant risks in this vulnerable pediatric population.
Introduction:
Severe and chronic illness can alter the bacterial flora carried in the oropharynx and gut. There are little data on the bacterial flora of children with chronic neurologic impairment.
Objectives:
To assess carriage of abnormal bacterial flora, antibiotic-resistant bacteria, infection, and mortality in children with cerebral palsy (CP) admitted for pediatric intensive care.
Design:
Prospective observational single center cohort study.
Setting:
Twenty-bed regional pediatric intensive care unit (PICU) in a university-affiliated tertiary referral children's hospital.
Patients:
All children with an established diagnosis of CP admitted to PICU and ventilated for four or more days during a 6-yr period.
Measurements:
Surveillance samples of throat and rectum were taken at admission to PICU and twice a week thereafter. Diagnostic samples were obtained on clinical indication.
Main Results:
Fifty-three children with a total of 77 admissions were included. Most (90%) of the children with CP had moderate to severe functional limitations. Eighty-nine percent of the children with CP (47/53) carried abnormal bacterial flora/potential pathogens, most frequently Pseudomonas and Klebsiella species. Forty-seven percent (22/47) had antibiotic-resistant bacteria. Thirty-five children (66%) developed 86 infections during their PICU admission. Lower airways and blood were the two most commonly infected sites-Pseudomonas aeruginosa and coagulase-negative Staphylococci, the predominant infecting microorganisms. Sixty-five percent (56/86) of infections were primary endogenous infections, 21% (18/86) exogenous, and 9% (8/86) secondary endogenous. Carriage of abnormal bacterial flora, antibiotic-resistant bacteria, and infection rate was significantly higher than that of children of comparative age without CP ventilated for four or more days on PICU. Nine (17%) of the children with CP died in PICU and 4 of the deaths were infection related.
Conclusions:
In children with moderate to severe chronic neurologic impairment admitted to PICU, there is a high rate of carriage of abnormal bacteria/potential pathogens, antibiotic-resistant bacteria, and infection.
