ABSTRACT
Background:
Intensive care unit (ICU) admission during hematopoietic stem cell transplant (HSCT) is associated with poor prognosis1,2. Published series report a range of ICU admission rates from 24-40% of transplant patients, most frequent reasons involving septic shock, respiratory failure and veno-occlusive disease3. In addition, patients undergoing HSCT are at a high risk of severe morbidity and mortality associated with COVID-194.Aims:
The aim of this study was to analyze outcome of HSCT patients requiring ICU admission in our center.Methods:
We retrospectively analysed outcome of 752 patients who underwent HSCT in our centre from January/2008 to June/2021. Data were collected from patients' clinical histories.Results:
103 (14%) patients required ICU admission (baseline and HSCT characteristics on table). Median time to ICU admission was 42 days (-2-1765). Seven of these patients were admitted to ICU on two occasions giving a total of 110 consecutive ICU admissions available for analysis. Main reason for ICU admission was respiratory distress (74;67%), mainly due to pneumonia (53%) including a 3% caused by COVID19, pulmonary edema (26%) and pulmonary haemorrhage (8%). Septic shock was second most common cause for ICU admission (26;24%) due to gram-negative bacilli (47%), fungal (15%) gram-positive bacteria (13%), virus (10%) and others/idiopathic (16%). Other less frequent causes were veno-occlusive disease (11;10%), hepatic failure/encephalopathy (8;7%), haemorrhagic complications (6;5%), cardiorespiratory arrest (2%), GVHD (2%), cardiogenic shock (2%). Of the 110 ICU admissions, 37 (34%) required hemofiltration, of which 30 (81%) died;and 77 (70%) required orotracheal intubation, of which 59 (77%) died. During the 110 ICU admissions, 67 patients (61%) died in the ICU;of these, 40 (37%) received unrelated donor HSCT, 36 (33%) sibling donor, 16 (15%) haploidentical and 17 (16%) autologous. Median ICU length of stay of these patients was 13 days (range 1-76). The cause of death was the same reason for ICU admission. Eighteen (16%) patients were discharged from ICU and died prior to Hospital discharge and 24 (22%) survived to Hospital discharge and were classified as post-discharge survivors. Of these 24 cases, 19 (79%) remain alive while the others (5;21%) succumbed to underlying disease or complications post-HSCT. Off note, both patients with COVID19 pneumonia (haploidentical and autologous HSCT respectively) were discharged from ICU and remain alive to date, without major complications. Summary/Conclusion:
In our study 14% of transplant recipients required ICU admission, slightly lower than previous reports. Most common cause of admission was respiratory failure, consistent with reported. Mortality rate during ICU admission was 61%;higher death rate observed in allogeneic transplantation and those requiring aggressive ICU treatments such as mechanical ventilation or hemofiltration. Although patients with COVID19 pneumoniae who require ICU admission are usually associated with adverse outcome, in our series they responded successfully to intensive treatment. ICU admission following HSCT is associated with poor prognosis, but should not be considered futile. (Table Presented).
