Nursing care of patients with relapsed and refractory multiple myeloma treated with B-cell mature antigen-targeted universal chimeric antigen receptor T cells.

Abstract

To investigate the efficacy of a nursing approach using B-cell maturation antigen (BCMA)-targeted universal chimeric antigen receptor T-cell (BCMA-UCART) immunotherapy in the treatment of 8 patients with relapsed refractory multiple myeloma (MM). In this study, 16 patients with relapsed and refractory MM who were treated with BCMA-targeted UCART in our department from May 2020 to November 2022 were selected, and were divided into a control group and an experimental group of 8 cases each according to the difference in the nursing methods, and the control group adopted the conventional universal nursing program. The experimental group used the nursing protocol that cooperated with the immunotherapy of this study, and the main points of nursing care included timely assessment of organ functional status, safe and accurate infusion of BCMA-UCART, identification and management of hyperthermia, hypotension, arrhythmia and central nervous system adverse reactions caused by cytokine release after BCMA-UCART infusion, as well as management of fluid imbalance, maintenance of stable blood pressure, and cooperation with physicians to effectively control of inflammatory factors. In addition, patients were provided with psychological and dietary support. The duration of hospitalization was compared between the two groups after the intervention. The discharge time of the experimental group was significantly shorter than that of the control group (P he.05), and the experimental group effectively controlled cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome and acute graft-versus-host disease. The nursing program with BCMA-UCART immunotherapy is effective in intervening MM patients and promotes their early recovery and discharge from the hospital.
