Filter by:To learn about the relationship between changes in pupil size and reactivity and the start of neurological side effects in patients after receiving CAR-T cell therapy.
The aim of this observational study is to answer the following questions in individuals with acute and chronic exposure to organophosphates. The main questions to be addressed are 1. What are the prognostic values of neuroinflammatory markers? 2. What are the genotoxic effects of organophosphates? 3. what are the changes occurring in the levels of traditional oxidative stress and inflammatory markers?
The aim of this study was to investigate the effects of chronic lead exposure on iron metabolism and the Nrf2-dependent ferroptosis pathway in lead acid battery factory workers
In this study, a 24-week randomized, sham-controlled, single-blind, multicenter clinical trial will be conducted to explore the effect of electroacupuncture for prevention and treatment of both acute and chronic neurotoxicity through both clinical and biological indicators.
The treatment of large-cell B-cell lymphomas refractory to more than 2 lines of therapy has recently been revolutionized by the use of immunotherapies consisting of autologous genetically modified cells or CAR-T CELLS (chimeric antigen receptor-T cells), which very significantly increase progression-free survival and overall survival. Nevertheless, this therapy is frequently associated with cytokine release syndrome and in approximately 20% to 60% of patients with neurological complications that can sometimes be dramatic and are associated with a significant mortality rate. The mechanisms behind this neurotoxicity are unclear. Despite the frequent occurrence of neurological toxicity characterized in particular by headache, tremor, and encephalopathy that is most often transient, brain imaging by CT or, preferably, MRI are most often normal. The rare abnormalities that have been identified suggest the presence of cytotoxic edema associated with the existence of transient modifications of the blood-brain barrier. To date, the management of neurotoxicity associated with CAR-T CELLS remains empirical. It combines early management of cytokine release syndrome (by administration of anti-IL6) and treatment with corticosteroids, the objective of which would be to control neurotoxicity more specifically. A better understanding of the pathophysiological mechanisms associated with this neurotoxicity appears essential today in order to be able to propose adapted prevention and treatment methods. Main objectives are to compare tissue permeability by quantitative MRI measurement of Ktrans to the theoretical peak of neurotoxicity between patients with CAR-T Cell-induced neurotoxicity and those without neurotoxicity and to Study, by MRI, the evolution of tissue microcirculatory parameters (from D-3 to D7) between groups of patients with or without the occurrence of neurotoxicity associated with CAR-T CELL treatment. For this purpose, 25 subjects will be included (the investigators hypothesize 40% with treatment-induced neurological impairment).
Sepsis is one of the most common causes of acute illness and death in the United States. Early, empiric broad-spectrum antibiotics are a mainstay of sepsis treatment. Two classes of antibiotics with activity against Pseudomonas, anti-pseudomonal cephalosporins and anti-pseudomonal penicillins, are commonly used for acutely ill adults with sepsis in current practice. Recent observational studies, however, have raised concern that anti-pseudomonal penicillins may cause renal toxicity. Anti-pseudomonal cephalosporins, by comparison, may be associated with a risk of neurotoxicity. Rigorous, prospective data regarding the comparative effectiveness and toxicity of these two classes of medications among acutely ill patients are lacking. The investigator propose a randomized trial comparing the impact of anti-pseudomonal cephalosporins and anti-pseudomonal penicillins on renal outcomes of acutely ill patients.
This is a randomized open label study in de novo liver transplant recipients that aims to compare the risk of tacrolimus induced tremors with once daily extended-release formulation, Envarsus, versus the twice daily immediate-release formulation. Both formulations of tacrolimus are currently approved for the prevention of rejection in liver transplant patients.
Immune effectors cells-associated neurotoxicity syndrome (ICANS) is one of the most clearly defined acute toxicities after CAR-T cells infusion. The investigators conducted a prospective cohort study of all patients who received CAR T cell infusions on the hematology department from Montpellier University Medical Center. Each patient was assessed between the 6th and 8th day after infusion by a neurological clinical examination, an electroencephalogram, and a brain MRI. The aim of the studies is to describe the EEG pattern associated with ICANS.
The investigators propose that immune effector cell-associated neurotoxicity syndrome (ICANS) is predicated upon the early loss of blood brain barrier (BBB) integrity with subsequent monocyte infiltration leading to cross-activation of native glial cells. Glial overstimulation leads to neuroinflammation, synaptic dysfunction, and ultimately neuronal injury.
This research study is studying the combination of anakinra and axicabtagene ciloleucel to reduce the occurrence of the side effects Cytokine Release Syndrome (CRS) and neurologic toxicities with relapsed or refractory Non-Hodgkin lymphoma (NHL). - Relapsed NHL is the condition of returned Non-Hodgkin lymphoma. - Refractory NHL is the condition of previous treatment resistant Non-Hodgkin lymphoma. - Cytokine Release Syndrome (CRS) is a group of side effect symptoms that can include nausea, headache, rapid heartbeat, shortness of breath, kidney damage, and rash. - Neurologic toxicity is nervous system disorder characterized by confusion This research study involves two drugs: - Anakinra - Axicabtagene Ciloleucel.
