Objectives: The aim of the study was to examine the incidence, baseline characteristics, and outcomes of Chimeric Antigen Receptor T-cell (CAR-T) therapy admissions in individuals who developed acute respiratory failure (ARF). The study utilized the National Inpatient Sample (NIS) database for the years 2017 to 2020. Methods: The study identified CAR-T cell therapy hospitalizations through the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) codes. Patients with acute respiratory failure (ARF) were further classified using specific International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM) codes. Descriptive statistics were performed to analyze baseline characteristics, comorbidities, complications, and outcomes. Results: Analysis of the NIS Database identified 5545 CAR-T therapy admissions between 2017 and 2020, revealing a rising trend over time. In our study, we found that hypertension (39%), dyslipidemia (21.7%), and venous thromboembolism (13%) were the most frequently observed comorbidities in CAR-T cell therapy admissions. Acute respiratory failure (ARF) was reported in 7.1% of admissions, and they had higher all-cause in-hospital mortality than CAR-T cell therapy admissions without ARF (32.9% vs 1.3%, P < 0.001). ARF admissions that required invasive mechanical ventilation (IMV) also had higher all-cause in-hospital mortality compared to admissions not requiring IMV (48.9% vs 11.8%, P = 0.001). There was no difference in the mortality rate among admissions with non-Hodgkin's Lymphoma, Multiple Myeloma, and Leukemia that utilized CAR-T therapy. Conclusions: In this largest study to date, we illuminate the incidence and outcomes of CAR-T cell therapy admissions with ARF. Higher mortality rates were observed in CAR-T cell therapy admissions with ARF. The study emphasizes the crucial role of interdisciplinary collaboration in CAR-T patient management and calls for additional research to clarify ARF's etiology and inform effective management strategies.

Purpose: Several studies show conflicting results regarding the prognosis and predictors of the outcome of critically ill patients with a solid malignancy. This study aims to determine the outcome of critically ill patients, admitted to a hospital, with a solid malignancy and the factors associated with the outcomes.

Introduction: Although there is evidence describing the immunomodulatory effects of macrolide antibiotics, there is little literature exploring the clinical effects these properties may have and their impact on measurable outcomes. Objective: The purpose of this study was to determine if empiric antimicrobial regimens containing azithromycin shorten time to shock resolution. Methods: A retrospective study was performed in adults with septic shock admitted to intensive care units (ICUs) of 3 university-affiliated, urban teaching hospitals between June 2012 and June 2016. Eligible patients with septic shock required treatment with norepinephrine as the first-line vasopressor for a minimum of 4 hours and received at least 48 hours of antimicrobial treatment from the time of shock onset. Propensity scores were utilized to match patients who received azithromycin to those who did not. Results: A total of 3116 patients met initial inclusion criteria. After propensity score matching, 258 patients were included, with 124 and 134 patients in the azithromycin and control groups, respectively. Median shock duration was similar in patients treated with or without azithromycin (45.6 hr vs 59.7 hr, P =.44). In-hospital mortality was also similar (37.9% vs 38.1%, P =.979). There were no significant differences in mechanical ventilation duration, ICU length of stay (LOS), or hospital LOS. Conclusions: In patients admitted to the ICU with septic shock, empiric azithromycin did not have a significant effect on shock duration, mechanical ventilation duration, ICU LOS, hospital LOS, or in-hospital mortality.
