Insights
Pediatric patients undergoing allogeneic hematopoietic stem cell transplant (allo-HSCT) have high PICU mortality. Aggressive cardiac support and low neutrophil counts post-transplant predict worse outcomes.
Area of Science:
- Pediatric Hematology/Oncology
- Bone Marrow Transplantation
- Pediatric Critical Care Medicine
Background:
- Allogeneic hematopoietic stem cell transplantation (allo-HSCT) can lead to life-threatening complications.
- A significant number of pediatric patients require Pediatric Intensive Care Unit (PICU) admission following allo-HSCT.
Purpose of the Study:
- To evaluate the incidence and outcomes of PICU admissions after pediatric allo-HSCT.
- To identify factors influencing survival in children admitted to the PICU post-allo-HSCT.
Main Methods:
- Retrospective chart review of 668 children undergoing their first allo-HSCT between 2005-2017.
- Focus on PICU admissions within one year post-transplant.
- Analysis of factors including mechanical ventilation (MV), cardiac support, and absolute neutrophil count (ANC).
Main Results:
- 8.7% of patients (58/668) required 64 PICU admissions.
- Mortality rate in the PICU was high, with 58.6% of admitted patients dying.
- Patients who died were more likely to require MV (91.2%), aggressive cardiac support (50%), and had lower ANC (P=.004) on the last PICU day.
- Five patients treated with non-invasive ventilation (NIV) survived >6 months post-discharge.
Conclusions:
- Pediatric PICU admissions after allo-HSCT are associated with high mortality.
- Intensity of cardiac support and ANC on the last PICU day are independent predictors of survival.
- While MV is linked to decreased survival, early NIV implementation may be beneficial.
Abstract:
Allo-HSCT is associated with life-threatening complications. Therefore, a considerable number of patients require admission to a PICU. We evaluated the incidence and outcome of PICU admissions after allo-HSCT in children, along with the potential factors influencing PICU survival. A retrospective chart review of 668 children who underwent first allo-HSCT in the Department of Pediatric Hematology/Oncology and BMT in Wrocław during years 2005-2017, particularly focusing on patients admitted to the PICU within 1-year post-HSCT. Fifty-eight (8.7%) patients required 64 admissions to the PICU. Twenty-four (41.5%) were discharged, and 34 (58.6%) patients died. Among the discharged patients, 6-month survival was 66.7%. Compared with survivors, death cases were more likely to have required MV (31/34; 91.2% vs. 16/24; 66.7% P = .049), received more aggressive cardiac support (17/34; 50% vs. 2/24; 8.3% P = .002), and had a lower ANC on the last day of their PICU stay (P = .004). Five patients were successfully treated with NIV and survived longer than 6 months post-discharge. The intensity of cardiac support and ANC on the last day of PICU treatment was independent factors influencing PICU survival. Children admitted to the PICU after allo-HSCT have a high mortality rate. Mainly those who needed a more aggressive approach and had a lower ANC on the last day of treatment had a greater risk of death. While requiring MV is associated with decreased PICU survival, early implementation of NIV might be considered.
