Hypothesis

Can CD64 and CD163 expression on neutrophils and monocytes discriminate between infectious and noninfectious SIRS in critically ill neonates and children?

Conclusion

CD64 and CD163 expressions on neutrophils and monocytes are elevated in critically ill neonates and children with SIRS with sepsis, and CD64 index for neutrophils is the most effective marker.

Supporting Evidence

  • CD64 and CD163 expressions were significantly higher in patients with SIRS with sepsis compared to those without.
  • Diagnostic accuracy of CD64 index for neutrophils was superior to other markers.
  • Statistically significant differences were found in CD64 and CD163 MFI between the two groups.

Takeaway

Doctors can use special markers in the blood to tell if very sick babies and kids have an infection or not.

Methodology

This was a prospective observational study measuring CD64 and CD163 expressions using flow cytometry in critically ill neonates and children with SIRS and suspected sepsis.

Potential Biases

Potential bias in the classification of patients by attending physicians unaware of flow cytometry results.

Limitations

The study had a relatively small sample size and the definition of clinical sepsis in culture-negative patients is debatable.

Participant Demographics

Participants included 56 critically ill neonates and children, with 29 having SIRS with sepsis and 27 without.
