Filter by:Immune-checkpoint inhibitors (ICIs) have radically changed the therapy of cancer in recent years. ICIs promote antitumor immune response inhibiting one of the following immune checkpoints: cytotoxic T-lymphocyte antigen-4 (CTLA-4; ipilimumab), programmed death-1 (PD-1: pembrolizumab, nivolumab, and cemiplimab), and programmed death ligand-1 (PD-L1: atezolizumab, durvalumab, and avelumab). Despite the desired effect as cancer treatment, ICIs can break immune tolerance to self-antigens and induce specific toxicities known as immune-related adverse events (irAEs), that may affect both peripheral and central nervous system (Neurological immune mediated adverse events, NirAEs). The pathogenic mechanisms underlying NirAEs are probably heterogeneous, as reflected by the variety of clinical phenotypes and severity. NirAEs are rare, but there is some concern that the incidence may increase in the next future, in particular because ICIs are being used more and more for cancers commonly associated with paraneoplastic neurological syndromes (e.g. small-cell lung cancer). Moreover, NirAEs are usually severe, and often fatal. Indeed, irAEs-related complications are the most common cause of death among these patients. On the other hand, these patients usually have a good tumor response to immunotherapy. There is some evidence that irAEs may predict ICIs efficacy and consequently NirAE surivors are likely to have longer life expectancy than non-NirAE patients. Therefore, it is of utmost importance to better characterize the long-term outcomes of NirAE patients in terms of neurologic disability and mortality, and to identify predictors of severe NirAEs. So far, only few studies with sufficient follow-up have been published on the topic, and they included only small number of patients. The aims of our study is to characterize the main clinical and paraclinical features of NirAEs in a large cohort of NirAE patients, to assess long-term outcomes and to identify prognostic factors. This study will help define new guidelines regarding NirAE prediction and management.
The compound ACTH4-10Pro8-Gly9-Pro10 is a synthetic analog molecule of an adrenocorticotropic hormone (ACTH) short fragment. That is free from hormonal effects and has neuromodulatory effects. We investigate the neuroprotective effects of ACTH4-10Pro8-Gly9-Pro10 can lessen neurotoxicity against ketamine in neonatal rats by looking at BDNF expression in the cortex and hippocampus tissue as well as BDNF blood levels.
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.
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.
A prospective feasibility trial initially including 10 patients to investigate if Neurofilament light protein can be detected in peripheral blood in patients undergoing Isolated Limb Perfusion with chemotherapeutic agents. This biomarker could act as predictive biomarker for neurotoxicity after isolated limb perfusion.
Taxane-induced peripheral neuropathy (TIPN) caused by paclitaxel is a dose-limiting toxicity. The main symptoms of discomfort are numbness, tingling, and burning sensations in the glove-sock-like distribution of the limbs. At present, there are few effective methods for clinical treatment of TIPN, and there is no widely agreed consensus on effective treatment in the world. Therefore, it is of great clinical significance and practical value to carry out clinical research to explore drugs to relieve TIPN.
The study report a unique case of severe intoxication in a child treated with oral ivermectin to prevent scabies infection. The ABCB1 gene sequencing found the child compound heterozygote for two nonsense mutations, one in each gene copy. The child had inherited from each parent one of the alleles. Each mutation generate a predicted truncated protein that likely lead to ABCB1 loss of function, and the undesirable effects observed. The study report a unique case of severe intoxication in a child treated with oral ivermectin to prevent scabies infection. The ABCB1 gene sequencing found the child compound heterozygote for two nonsense mutations, one in each gene copy. The child had inherited from each parent one of the alleles. Each mutation generate a predicted truncated protein that likely lead to ABCB1 loss of function, and the undesirable effects observed. While in some animals, nonsense ABCB1 mutations can lead to neurotoxicity of several ABCB1-substrate drugs, in humans, ivermectin was considered to have an especially high margin of safety, and nonsense mutations have never been reported before, nor has the neurotoxicity of ivermectin apparently caused by these two mutations never been reported before. This discovery is of critical importance for the child, since it dictates that clinicians would need to optimize any ABCB1 substrate-based therapy in the future. More generally, such information must be brought to the attention of clinicians' medics, and in particular infectious disease specialists, pediatricians, and general practitioners. It points the importance of pharmacovigilance, and the benefit of pharmacogenomic genotyping in well-defined phenotype, still too rarely considered in clinical practice before the implementation of a drug treatment. This work results from a multidisciplinary approach, combining several areas of expertise in clinical pediatrics, pharmacology, biology, and bioinformatics.
This study will compare neurologic side effects associated with two immunosuppressant medications used in liver transplant patients. The standard therapy of twice daily immediate release Tacrolimus will be compared to Envarsus once daily. We hypothesize that Envarsus will show a lower rate of neurologic side effects than immediate release tacrolimus.
This is a diagnostic test accuracy study. The investigators measure optic nerve sheath diameter (ONSD) by ultrasound on the eye during living donor liver transplantation operation at 5 minutes after reperfusion to predict the occurrence of early tacrolimus neurotoxicity after liver transplantation. We measured the ONSD at 4 timings: (T1) Post induction and before surgical incision, (T2) Portal vein clamping, (T3) 5 minutes after reperfusion, and (T4) 30 min after reperfusion.
Nowadays there is increasing doubts about the safety of anesthesia . Anesthesiologists have to console the worried patients, who are anxious about the potential risks of anesthetic-induced brain damage, by suggesting that any detrimental effects would be "mild".Anesthetics are responsible for postoperative taste and odor defects and cognitive dysfunction.
