OBJECTIVE: Our primary objective was to describe the baseline characteristics, main reasons for intensive care unit (ICU) admission, and interventions required in the ICU across patients who received CAR-T cell immunotherapy. The secondary objectives were to evaluate different outcomes (ICU mortality) across patients admitted to the ICU after having received CAR-T cell therapy.
MATERIALS AND METHODS: We performed a medical literature review, which included MEDLINE, Embase, and Cochrane Library, of studies published from the inception of the databases until 2022. We conducted a systematic review with meta-analyses of proportions of several studies, including CAR-T cell-treated patients who required ICU admission. Outcomes in the meta-analysis were evaluated using the random-effects model.
RESULTS: We included four studies and analyzed several outcomes, including baseline characteristics and ICU-related findings. CAR-T cell recipients admitted to the ICU are predominantly males (62% CI-95% (57-66)). Of the total CAR-T cell recipients, 4% CI-95% (3-5) die in the hospital, and 6% CI-95% (4-9) of those admitted to the ICU subsequently die. One of the main reasons for ICU admission is acute kidney injury (AKI) in 15% CI-95% (10-19) of cases and acute respiratory failure in 10% CI-95% (6-13) of cases. Regarding the interventions initiated in the ICU, 18% CI-95% (13-22) of the CAR-T recipients required invasive mechanical ventilation during their ICU stay, 23% CI-95% (16-30) required infusion of vasoactive drugs, and 1% CI-95% (0.1-3) required renal replacement therapy (RRT). 18% CI-95% (13-22) of the initially discharged patients were readmitted to the ICU within 30 days, and the mean length of hospital stay is 22 days CI-95% (19-25). The results paint a current state of matter in CAR-T cell recipients admitted to the ICU.
CONCLUSIONS: To better understand immunotherapy-related complications from an ICU standpoint, acknowledge the deteriorating patient on the ward, reduce the ICU admission rate, advance ICU care, and improve the outcomes of these patients, a standard of care and research regarding CAR-T cell-based immunotherapies should be created. Studies that are looking from the perspective of intensive care are highly warranted because the available literature regarding this area is scarce.
