The field of chimeric antigen receptor (CAR) T-cell therapy has grown from a fully experimental concept to now boasting a multitude of treatments including six FDA-approved products targeting various hematologic malignancies. Yet, along with their efficacy, these therapies come with side effects requiring timely and thoughtful interventions. In this review, we discuss the most common toxicities associated with CAR T-cells to date, highlighting risk factors, prognostication, implications for critical care management, patient experience optimization, and ongoing work in the field of toxicity mitigation.

The efficacy of CD19 chimeric antigen receptor (CAR) T cells in B cell malignancies has generated recent interest in their application to other B cell-related pathologies, such as autoimmune diseases. Fischbach et al. report on the use of CD19 CAR T cells in two patients with progressive multiple sclerosis, demonstrating feasibility and safety for the first time in this disease process.

Introduction: While CAR T-cell therapy has led to remarkable responses in relapsed B-cell hematologic malignancies, only 50% of patients ultimately have a complete, sustained response. Understanding the mechanisms of resistance and relapse after CAR T-cell therapy is crucial to future development and improving outcomes.

Areas Covered: We review reasons for both primary resistance and relapse after CAR T-cell therapies.

Article Synopsis
  • - The study assessed how trametinib, a RAS-MAPK pathway inhibitor, affects difficult-to-treat chylous effusions in three hospitalized patients with Noonan syndrome.
  • - All patients exhibited significant improvements, including reduced lymphatic leaks and better overall health indicators such as growth, heart function, and blood health after undergoing MEK inhibition treatment.
  • - While trametinib was generally safe, causing only mild skin irritation in one patient, more extensive studies are necessary to further confirm its effectiveness and long-term safety for this group.

Introduction: Red blood cell (RBC) transfusions are important in the management of patients with sickle cell disease (SCD). However, a potentially catastrophic complication of transfusion in this population is the delayed hemolytic transfusion reaction (DHTR). The pathophysiology of all DHTRs is not understood, but some are known to be caused by an anamnestic resurgence of RBC alloantibodies.

Background: Patients with sickle cell disease (SCD) are frequent recipients of red blood cell (RBC) transfusions and are at risk for RBC alloimmunization. RBC alloimmunization is diagnosed by identifying RBC alloantibodies as part of pre-transfusion testing, but this testing fails to detect alloantibodies that have evanesced. It may be beneficial to screen for new RBC alloantibody development after transfusion before possible antibody evanescence.

Food-storing birds demonstrate remarkable memory ability in recalling the locations of thousands of hidden food caches. Although this behaviour requires the hippocampus, its synaptic mechanisms are not understood. Here we show the effects of cannabinoid receptor (CB1-R) blockade on spatial memory in food-storing black-capped chickadees (Poecile atricapilla).

Food-storing birds use a form of long-term memory to recover their hidden food caches that depends on the hippocampal formation (HF). The authors assessed whether food-storing birds' long-term memory for spatial locations requires N-methyl-D-aspartate receptor (NMDA-R)-dependent synaptic plasticity. Black-capped chickadees (Poecile atricapilla) were given bilateral infusions of the NMDA-R antagonist AP5 into the hippocampus, and their memory on a spatial reference memory task was assessed.

An interactive data management (IDM) system for the Spinal Cord Injury (SCI) Service was developed to collect self-reported patient data related to secondary medical complications and to provide feedback to the SCI rehabilitation team. The long-term objective is to improve clinical care through a process of staff review of current rehabilitation programs in the areas of prevalence, prevention, and management. Based on data from the first 99 SCI patients visiting the clinic and hospital after the installation of the IDM system, SCI patients reported high rates of current problems with spasticity (53 percent), pain (44 percent), and pressure ulcers (38 percent).
