Filter by:Influenza infection occurring during oncologic treatment or following hematopoietic cell transplantation (HCT) is associated with increased risk of morbidity in the form of lower respiratory tract infection (LRTI) and mortality relative to otherwise healthy patients. The study participants have been diagnosed with a hematological malignancy and are eligible to receive the current seasonal influenza (Flu) vaccine. Primary Objective - To determine the feasibility of opening a longitudinal prospective study of IIV immunogenicity in pediatric leukemia patients. - To describe the immunogenicity, as measured by the development of cell- and/or antibody-mediated influenza specific responses 3 to 5 weeks following vaccination, in a cohort of pediatric leukemia patients. Secondary Objectives - To describe whether an immune response, as measured by development of cell- and/or antibody-mediated influenza specific responses, is detectable 1-2 weeks following vaccination in a cohort of pediatric leukemia patients. - To describe the durability of immunogenicity by measuring cell - and antibody- mediated influenza specific responses at 6 months and 1 year following vaccination in a cohort of pediatric leukemia patients. Exploratory Objectives - To estimate the clinical effectiveness of influenza vaccine in this cohort by monitoring for the development of clinical diagnosis of influenza in the cohort of enrolled pediatric oncology patients. - To correlate results of immune cell frequency in blood, as measured by complete blood count with differential, with development of an immune response to IIV.
Previous studies had found that the microbe in intestinal after allogeneic hematopoietic cell transplantation(allo-HSCT) were closely associated with overall survival and post-transplantation complications, especially graft versus host disease (GVHD).Due to the limited data on the association of microbiota composition with chronic GVHD(cGVHD) after allogeneic hematopoietic stem cell transplantation, the relationship between microbiota composition and post-transplantation complications, especially cGVHD, needs to be further evaluated.Detailed studies of the microbiome and host immune system will lead to the discovery of microbiome markers for early identification of patients at high risk for cGVHD. This may regulate patients' gut microbiota in an individualized manner to achieve optimal treatment outcomes while avoiding severe post-transplant cGVHD. We will operate a prospective, multicenter, nonrandomized, observational study. Patients will be asked to provide blood and stool samples during allo-HSCT.
Some of the treatments for cancer can cause platelets (the part of the blood that helps with clotting) to decrease. If they are too low, then clinicians may recommend a transfusion (getting platelets from another person added to someone else's body). This usually works to increase the person's platelets to a healthy level, but sometimes it doesn't work. This is called platelet refractoriness. This study is trying to find out whether isatuximab (the study drug) may help people with a certain type of platelet refractoriness by removing some cells in order to make platelet transfusions more effective.
This phase I/II study the side effects and efficacy of natural killer cells after donor stem cell transplant and how they treat patients with myeloid malignancies or lymphoproliferative disorders. Investigators expanded NK cells ex vivo with a non-feeder cell regimen to avoid the risk of infusion of feeder cells with expanded NK cells. Investigators infuse NK cells after myeloablative conditioning therapy. These cells may help decrease relapse of malignant disease, severe graft versus host disease, reactivation of certain viruses, and, therefore, prolong the survival of participants.
The purpose of this project is to investigate the effects of 12 weeks of high-intensity interval training (HIIT) and resistance training on several domains of health including physical function, cognitive function, mental health, and quality of life in patients who have undergone hematopoietic stem cell transplant (HCT). In addition, the project will determine the effects of 12 weeks of HIIT and resistance training on physical function, caregiver strain, mental health, and caregiver confidence in individuals who are providing care for patients undergoing HCT.
This study is being done because the investigators would like to learn more about how well the COVID-19 vaccine works in participants with cancer or those who have received a transplant or cellular therapy. Primary Objective Assess the immunogenicity to COVID-19 vaccination in patients with cancer and/or transplant and cellular therapy (TCT) recipients. Secondary Objectives - Evaluate the antibodies response to COVID-19 vaccination in immunocompromised patients. - Evaluate the T cell response to COVID-19 vaccination in immunocompromised patients. Exploratory Objectives - Assess incidence and severity of COVID-19 infections by 6 months following immunization with a SARS CoV-2 vaccine. - Assess the durability immune response to COVID-19 vaccination. - Assess the immunogenicity of COVID-19 vaccination in immunocompetent children and adolescents without cancer and have not undergone transplant or received cellular therapy.

During the last decades hematologists have excelled at improving and refining the classification, diagnosis, and thus ultimately the therapeutic decision-making process for their patients. This continuous evolution proceeded in parallel to seminal discoveries in basic science such as FISH, PCR and NGS. So far, the current WHO classification serves as reference to diagnostic decision making and is largely based on 5 diagnostic pillars: cytomorphology of peripheral blood and/or bone marrow smears, histology and immunohistochemistry of bone marrow trephine biopsies or lymph nodes, immunophenotyping, chromosome banding analysis supplemented by FISH analysis, molecular genetics including PCR and targeted panel sequencing via NGS. This leads to a swift diagnosis in 90 % of all cases. The leftover 10 % remain a challenge for hematopathologists and clinicians alike and are resolved through interdisciplinary teams in the context of specialized boards. With the advent of high throughput sequencing (mainly WGS and WTS) the possibility of a comprehensive and detailed portrait of the genetic alterations - specifically in challenging cases - has become a realistic alternative to classical methods. In SIRIUS the investigators will prospectively challenge this hypothesis to address the question of how often a better or final diagnosis can be delivered by WGS and/or WTS and if unclear cases can be efficiently resolved.
Medical procedures can be a very frightening experience for children. It is known that children who received painful medical procedures can develop a higher sensitivity of pain during their following experiences. During their treatments for malignant diseases, children are exposed to a lot of painful procedures (eg. needle insertion, lumbar punction, myelogram, etc…) Therefore, medical societies propose the use of interventions like distraction techniques for pain management in complement of pharmacological treatment. In addition, the repetitions of painful procedures and ineffective prevention of pain can create care phobia. Within this context, immersive and participative virtual reality (VR) could be an innovative distraction technique for pain management among children undergoing medical procedures. Attention Pain Theory can explain how virtual reality can reduce the perception of pain. Attention is required to feel pain. When the patient is focused on another subject like an immersive virtual environment, his brain is less available to treat information like painful stimulus from care procedures. The investigators hypothesis is that VR can reduce procedural-related pain and can decrease fear during the following procedures. Results of previous studies are varied : some showed a non-significant reduction of patient's procedural pain despite the use of VR, whereas others concluded to a decrease of pain. The question of the benefit of VR for the patients who are exposed to repeated painful procedures remains still unclear, especially with patients who are likely to feel chronic pain or many pain-related exposures. The aim of this study is to evaluate the non-inferiority of virtual reality as a distraction technique for pain management in children and adolescents with onco-hematological diseases, undergoing painful procedures, compared to standard of care.
Single-site non-significant risk, open-label clinical investigation designed to validate the usability, adherence, and preliminary diagnostic performance of a novel technology to detect neutropenia. Study participants will be managed as per the standard of care practice with a baseline and nadir visit including laboratory determinations. Participants will also be evaluated with the device at both time points and with daily measurements during the two-week period in between.
