Filter by:The investigators aim to explore a new EBV DNA surveillance method with both high sensitivity and specificity in nasopharyngeal carcinoma (NPC) patients. the investigators aim to conduct plasma EBV DNA counting by next generation sequencing (NGS) in non-metastatic NPC patients on their diagnose, after two cycles of induction chemotherapy (IC), and 4-8 weeks after definitive radiotherapy. The investigators aim to explore whether sequencing-based counting is better than PCR analysis in plasma EBV-DNA surveillance, so as to monitoring tumor responses to treatment and for guiding individualized treatment adaptation in the future.
The purpose of this study is to evaluate the safety and preliminary efficacy of ATA3219 in participants with relapsed/refractory (R/R) B-cell non-Hodgkin Lymphoma (NHL).
The goal of this prospective cohort study is to investigate the associations between Epstein-Barr Virus (EBV) antibody levels and the risk of overall and site-specific cancer types in Southern China. The main questions it aims to answer are: Question 1: In addition to the established EBV-associated cancer types, such as lymphomas, nasopharyngeal carcinoma, and stomach cancer, whether EBV is associated with other cancer types? Question 2: What's the cancer burden attributed to EBV in Southern China?
This is a multi-center, single arm, open-label, phase I study to determine the safety and effectiveness of EBV-TCR-T cell immunotherapy in treating EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) or EBV infection
This is a multi-center, single arm, open-label, phase I study to determine the safety and effectiveness of EBV-TCR-T cell immunotherapy in treating EBV virus infection after allogenic HSCT.
The purpose of this registry study is to create a database-a collection of information-for better understanding T-cell lymphoma. Researchers will use the information from this database to learn more about how to improve outcomes for people with T-cell lymphoma.
This research study is evaluating the combination of drugs, pembrolizumab with chimeric antigen receptor (CAR) T-cell therapy, as a possible treatment for primary mediastinal B-cell lymphoma that has recurred after prior treatment. The names of the study drugs involved in this study are: - Pembrolizumab Standard treatment will include: - CAR T-cell therapy (either axicabtagene-ciloleucel or lisocabtagene maraleucel) - Cyclophosphamide - Fludarabine
This prospective case-control study aims to evaluate the immune function and find PD-1 antibody efficacy predictors on Chronic Active Epstein-Barr Virus Infection and Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis by detecting lymphocyte subsets proportions in peripheral blood mononuclear cells and the positive proportion of PD-1, PD-L1 and other indicators in each lymphocyte subsets in healthy people and patients using flow cytometry before and after the initial PD-1 therapy.
The clinical course of RRMS patients is variable. Among RIS-Consortium international cohorts, one third of RIS patients progressed to MS at 5 years and 52.2% at 10 years. Biomarkers predictive of MS conversion are key elements to organize personalized medical care, for both follow-up and treatment strategies. EBV seems to be an interesting candidate regarding its involvement MS pathophysiology. It can be easily assess in blood sample in contrast to others prognostic biomarkers validated in RIS : oligoclonal bands and NfL levels in cerebrospinal fluid and serum. In RIS, treatment targeting EBV could significantly modify the course of the disease. The investigators aim to make the fisrt description of the EBV epidemiology (immunoglobulin (Ig)M and IgG anti-viral capsid antigen (VCA), IgG anti Epstein-Barr nuclear antigen (EBNA)) among RIS patients and to investigate a correlation between the different antibodies' titers (IgM VCA, IgG VCA, IgG EBNA) and the course of the disease (clinical conversion or evidence of disease activity (EDA)).
Chronic fatigue syndrome (syn. myalgic encephalomyelitis or ME/CFS) is a relatively common, but pathogenetically still insufficiently understood, complex, severe, chronic disease. It has been classified by the WHO as a neurological disorder (ICD-10 G93.3). The leading symptoms are pathological exhaustion (fatigue) and prolonged, inadequate deterioration of condition after exertion (syn. post-exertional malaise or PEM). In addition, pain, sleep disturbances, flu-like symptoms, and cognitive, autonomic, and neuroendocrine symptoms are typically found. In the majority of patients*, the trigger is a viral disease, including infectious mononucleosis caused by Epstein-Barr virus (EBV), which is particularly common in young patients, but also influenza or coronavirus disease 2019 (Covid-19) at any age. Causative factors are discussed to be autoimmune mechanisms as well as a genetic predisposition. The general activity level and quality of life of patients are usually significantly reduced due to the disease. A large proportion of those affected are confined to a wheelchair, home or bed. ME/CFS is one of the most common reasons for long absences from school due to illness. Because no reliable biomarkers are available, ME/CFS is a diagnosis of exclusion. The diagnosis is made using internationally established clinical criteria and after careful differential diagnosis. To date, no causal, but only symptom-oriented, non-standard treatment approaches are found. With appropriate care, the prognosis in childhood and adolescence is better than in adults. Long-term recovery is possible in two-thirds of young patients, whereas less than one-third of adult patients can expect recovery. In Germany, there are currently two special outpatient clinics for patients with ME/CFS, one for adult patients* at the Charité Fatigue Centrum in Berlin, headed by Prof. Scheibenbogen, and one for children, adolescents and young adults up to 25 years of age at the ME/CFS focus of the Children's Polyclinic of the MRI of the TUM in Munich, headed by Prof. Behrends. A joint data collection of these ME/CFS centers has not been established. The proposed ME/CFS registry study (MECFS-R) is intended to initially pool medical data from specialized routine care on a bicenter basis and, after recruitment of additional German centers, on a multicenter, longitudinal, and web-based basis, as extensive as possible, and to make this data available for research. Following the example of already well-established European registry studies (e.g., the ESID registry of the European Society for Immunodeficiencies), digital data acquisition should take place in a tiered approach according to cost-benefit analysis. Medical institutions can decide, based on capacity, whether a clearly defined core data set (level 1) or more complex data sets (level 2 or 3) should be digitally captured. The digital implementation is to be carried out in collaboration with the Munich-based IT company Bitcare, whose database concepts have proven successful in the context of the Transplantation Cohort (Tx Cohort) of the German Center for Infection Research (DZIF) or the Covid-19 study of the MRI of TUM (COMRI) and with whom the team at the MRI of TUM has been working successfully for many years. The aim of the MECFS-R is to accurately describe the clinical picture and its course in Germany clinically and epidemiologically as well as to derive epidemiological or medical risk factors, if applicable, and to define subcohorts for future treatment approaches.
