Indications for HSCT
Introduction
Complications
ICU admission for HSCT patients
Neither disease status at transplantation
nor transplantation-related characteristics
influenced the in-hospital outcome in
allogeneic HSCT recipients
- The overall in-ICU, in-hospital, 6-month, and 1-year survival rates were 48.3%,
32.5%, 27.2%, and 21%, respectively;
- Mechanical ventilation, elevated bilirubin level (and corticosteroid treatment
for the indication of active graft-versus-host disease (GVHD)) were
independent predictors of death in the whole cohort;
- In the subgroup of patients requiring mechanical ventilation, associated organ
failures, such as shock and liver dysfunction, were independent predictors of
death;
- ICU admission during engraftment period was associated with acceptable
outcome in mechanically ventilated patients, whereas patients with late
complications of HSCT in the setting of active GVHD had a poor outcome

Far from 60-70% of

PICU admission for Pediatric HSCT patients
- Admission rate ̴ 23% [Platon et al, BMT 2015]
- Mortality decresing over time?

ECMO for Pediatric HSCT patients
29 patients (ELSO registry between
1991-2012):
-23 (79%) died during ECMO
- 6 (21%) survived ECMO
- 3 (10%) discharged
ECMO should be considered in:
1) HSCT patients with either nonmalignant
disorders or with malignancies at low risk of
recurrence
2) when engraftment is acquired
3) when an effective etiologically targeted
treatment of the HSCT complications is available

Conclusions
- PCCM physician plays an important role in the management
of pediatric patients undergoing HSCT;
- A tight cooperation between PCCM and BMT physician
seems to ameliorate the outcome of children who received
an HSCT;
- Despite improvements in supportive care, mortality remains
high; thus, new approaches/treatment strategies are
desirable;
- Since robust data on PICU admission for pediatric patients
undergoing HSCT are lacking, well-designed studies will
clarify indications to (and timing for) PICU admission,
prognostic factors and optimal treatment program in this
setting.
