Insights
Primary immunodeficiency (PID) patients admitted to the pediatric intensive care unit (PICU) have a 56% survival rate. Mechanical ventilation, organ failure, and renal replacement therapy are key mortality risk factors.
Area of Science:
- Pediatric critical care medicine
- Immunology
- Clinical outcomes research
Background:
- Primary immunodeficiency (PID) encompasses a heterogeneous group of genetic disorders affecting the immune system.
- Patients with PID are susceptible to severe infections and may require intensive care.
- Understanding the outcomes and risk factors for PID patients in the pediatric intensive care unit (PICU) is crucial for improving management.
Purpose of the Study:
- To determine the frequency, characteristics, and clinical course of PID patients admitted to the PICU.
- To identify factors associated with mortality in this patient population.
- To provide insights for predicting poor outcomes and guiding intensive care.
Main Methods:
- A retrospective review of pediatric patients (1 month to 18 years) with PID admitted to a tertiary teaching children's hospital's PICU between January 2002 and January 2012.
- Data collected included diagnoses, reasons for admission, treatments received (e.g., hematopoietic stem cell transplantation), and outcomes.
Main Results:
- A total of 51 patients accounted for 71 PICU admissions; severe combined immunodeficiency was the most common diagnosis.
- Respiratory problems were the leading cause for admission.
- Overall survival was 56% across all admission episodes. Significant risk factors for mortality included mechanical ventilation, multiple organ system failure, renal replacement therapy, inotrope use, higher PELOD scores, and longer PICU stays.
Conclusions:
- This study provides the first comprehensive analysis of outcomes and mortality risk factors for PID patients in the PICU.
- Effective PICU management is as vital as early diagnosis and treatment for PID patients.
- Identifying patients at high risk for adverse outcomes can aid in optimizing intensive care strategies and improving survival rates.
Purposes:
The aims of this study were to review the frequency, characteristics, and the clinical course of primary immunodeficiency (PID) patients admitted to pediatric intensive care unit (PICU) and attempt to identify factors related with mortality that might predict a poor outcome.
Methods:
We performed a retrospective review of children with PID aged 1 month to 18 years and admitted to PICU from January 2002 to January 2012 in our tertiary teaching children's hospital.
Results:
There were a total of 51 patients accounting for 71 admissions to the PICU. The most common diagnosis was severe combined immunodeficiency. Respiratory problems were the leading cause for admission. A total of 20 patients received hematopoietic stem cell transplantation. Immune reconstitution was achieved in 9 (45 %) patients and eight of them did survive. In all 56 % of all admission episodes resulted in survival. Risk factors for mortality included requirement of mechanical ventilation (P < .001), number of organ system failure (P = .013), need for renal replacement therapy (P < .001), use of inotropes (P < .001), higher Pediatric Logistic Organ Dysfunction (PELOD) score (P = .005), and length of PICU stay (P < .001).
Conclusions:
This is the first study regarding the outcome and mortality-related risk factors for PID patients requiring PICU admission. We suggest that PICU management is as important as early diagnosis and treatment for these patients. Prediction of those at risk for poorer outcome might be beneficial for accurate intensive care management and survival.
