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).
Study the effect of genetic polymorphism (rs1885301, rs4148396 and rs3740066) in the membrane of Multidrug resistance protein 2 (MRP2) encoded by ATP-binding cassette C2 (ABCC2) gene and its genetic expression levels on neurotoxicity in gasrtointestinal cancer patients reciving Oxaliplatin-based chemotherapy.
To assess if biomarkers can be used to predict early treatment related neurotoxicity in patients with Acute lymphoblastic leukaemia (ALL) or lymphoblastic lymphoma (LBL) and to inform development of novel interventions.
Background: CAR T-cell therapy is a promising new treatment for blood cancers. During treatment, a person s T-cells are genetically changed to kill cancer cells. Researchers want to learn more about the effects of potential problems that may be associated with this treatment. We are specifically interested in learning if and how this treatment may affect the brain or your thinking skills. Objective: To learn if CAR T-cell therapy can affect how children and adults think, process, and remember things. Eligibility: People aged 5-35 who have blood cancer that has not responded to treatment, or the blood cancer has come back after treatment, and who will receive CAR T-cell therapy. Caregivers are also needed. All participants must be able to speak and read in English or Spanish. Design: Participants will be screened with a medical history. Information from participants medical records will be collected. Participants will take tests at home or at NIH to see how well they think, read, learn, remember, reason, and pay attention. The tests will be both computerized and paper/pencil. They will take less than 1 hour to complete. Participants and a parent/adult observer will complete a 5-minute Background Information Form and a checklist of nervous system symptoms. If participants are 5 years or older, they will participate in activities to test their ability to do different thinking tasks, like answer questions, complete puzzle patterns, and remember things. Participants and their caregivers will complete questions to see if they are having specific symptoms related to receiving CAR T-cells. The questions will assess their well-being and needs. The questions will take less than 1 hour to complete. Some tests and questions will be repeated at different time points in the study. Participation will last for up to 3 years.
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.
Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent side effects caused by antineoplastic agents, with a prevalence from 19% to over 85%. Clinically, CIPN is a mostly sensory neuropathy that may be accompanied by motor and autonomic changes of varying intensity and duration. Due to its high prevalence among cancer patients, CIPN constitutes a major problem for both cancer patients and survivors as well as for their health care providers, especially because, at the moment, there is no single effective method of preventing CIPN; moreover, the possibilities of treating this syndrome are very limited. The phycocyanin (PC), a biliprotein pigment and an important constituent of the blue-green alga Spirulina platensis, has been reported to possess significant antioxidant and radical-scavenging properties, offering protection against oxidative stress. Study hypothesis is that phycocyanin may give protection against oxaliplatin-induced neuropathy in the treatment of gastro intestinal cancers including oesogastric, colo-rectal and pancreatic cancers. This trial will be a randomised placebo-controlled study.
This is a pilot, observational, cross-sectional, study on socio-economic burden related to chemotherapy-induced peripheral neurotoxicity (CIPN). Investigators will collect CIPN healthcare related costs on a detailed clinical patient-level. As a sub-study, data obtained in this cross-sectional study, will be compared with administrative larger datasets on patients affected by cancer. The aim is to run a test for potential proxy variables which are available in larger administrative datasets, even if not directly measuring CIPN, to learn more about the impact of CIPN.
