Association between platelet count and multiorgan dysfunction and outcomes in patients with sepsis in the pediatric...

Area of Science:

• Pediatric critical care medicine
• Hematology
• Infectious diseases

Background:

• Sepsis poses a significant global threat to children, causing substantial morbidity and mortality.
• Understanding prognostic indicators in pediatric sepsis is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the correlation between platelet count and outcomes in pediatric severe sepsis and septic shock.
• To determine if thrombocytopenia serves as a predictive marker for sepsis severity and survival in children.

Main Methods:

• Retrospective cohort study of pediatric patients (newborns to 14 years) with sepsis or septic shock admitted to the PICU.
• Patients were categorized into thrombocytopenia (platelet count <150,000/μL) and non-thrombocytopenia groups.
• Data collected included mortality, bacterial blood culture results, and incidence/progression of multiorgan dysfunction syndrome (MODS).

Main Results:

• Thrombocytopenia was observed in 39.8% of the enrolled pediatric sepsis patients.
• A higher mortality rate (29%) was associated with the non-thrombocytopenia group compared to the thrombocytopenia group (12.2%).
• Thrombocytopenia was more prevalent in cases with negative bacterial blood cultures, suggesting an association with non-bacterial sepsis.

Conclusions:

• Low platelet count (thrombocytopenia) in pediatric sepsis patients may be linked to a better clinical outcome.
• Thrombocytopenia appears to be associated with non-bacterial forms of sepsis/septic shock.
• Platelet count can be a valuable indicator for predicting outcomes in pediatric severe sepsis and septic shock.
