Active clinical trials for "Hematologic Neoplasms"

This research study is looking at a small device that measures white blood cell (WBC) counts by being placed against the finger nail for participants who are undergoing stem cell transplantation at Massachusetts General Hospital or have a hematologic malignancy and are being seen as an outpatient.

The main objective of this study is to assess the safety of administering intravenous (IV) pentamidine for Pneumocystis jirovecii pneumonia (PJP) prophylaxis in adult inpatients with hematologic malignancies and stem cell transplant recipients. There will also be an assessment of patient satisfaction associated with intravenous pentamidine PJP prophylactic therapy.

The decision to limit or withdraw specific therapies (DLWT) in patients with advanced cancer is a complex process that is always painful for patients, relatives and professionals. For more than 10 years, shared decision making has been more and more emphasized. However, few data in the literature rely on clinical research. In order to understand their difficulties and issues, this study explores the determinants and modalities of DLWT and analyses the feasibility of different methods for investigating this decision making process.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease characterized by an aggressive clinical behavior and a poor prognosis. It predominantly affects elderly males with an average age of 67 years at diagnosis and the affected organs are usually the skin, bone marrow, lymph nodes and the central nervous system. Patients with BPDCN have poor outcomes with median overall survival (OS) ranging in the largest series of patients from 8 to 12 months. Patient care must be defined in this pathology. Despite 40%-90% complete remission (CR) rates after initial chemotherapy, relapses are almost inevitable. The investigators have developed a national network to collect clinical and biological data of French patients diagnosed with BPDCN.

ECP will be given to the patients [UVAR®XTS TM Therakos system, Johnson & Johnson] according to the following schedule: Starting at day 21 after transplant, if hematologic recovery allowed it: 2 ECP per week the first 2 weeks, and 1 ECP per week during 1 month. Total = 8 ECP after transplantation.

Bone marrow transplantation (BMT) has revolutionized the treatment of hematopoietic malignancies.Unfortunately, graft versus host disease (GvHD) remains a major toxicity that greatly limits the application and efficacy of BMT.Current standard prophylaxis and therapy for acute GvHD include mainly the use of immunosuppressive drugs that help less than 50% of the patients and are associated with increased infection risk. ApoCell treatment is anticipated to be a prophylactic measure for acute GvHD by inducing tolerance in the donor effector cells, leading to a potentially significant decrease in GVHD.

The aim of this study is to compare the efficacy and tolerance of piperacillin-tazobactam versus piperacillin-tazobactam plus glycopeptide as initial empiric antibiotic treatment for fever in neutropenic patients. Study of consecutive cohorts(2). First the patients will be included in the monotherapy branch until completing the predicted number of cases. When this happens, the Coordinating Center will communicate it to the participant centers and from then the patients will be included in the combined therapy.

Fludarabine and clofarabine are chemotherapy drugs used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of clofarabine and fludarabine in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that clinical and individual factors cause changes in clofarabine and fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.

Unicentric retrospective analysis of a cohort of 602 young adult and adolescent patients, aged 15 to 30 years, with haematological malignancies, and managed between 2000 and 2016

Torque Teno Virus (TTV) prevalence in the general population is very high (>90%) and has not been consistently confirmed to cause any disease. Kidney transplant studies seem to indicate that an elevated viremia could predict the risk of de-veloping an infectious process in the following weeks. An study of the influence of TTV as a predictive marker of infection in kidney transplant recipi-ents showed higher TTV levels, even 3 months before the infectious process, allowing the authors to postulate that the quantification of TTV could help to modulate the treatment of patients at risk. Publications of subsequent studies seem to confirm these data.In the field of hematopoietic stem cell transplantation (HSCT) few studies have analyzed the replication kinetics of TTV. There seems to be a drop in TTV plasma load after conditioning treatment, with a progressive increase in the first months post-transplant, in parallel with the number of lymphocytes. In early stages of HSCT, a relation-ship between TTV replication kinetics and the probability of developing an infection by CMV has also been described. Likewise, the possible relationship of TTV with other complications of HSCT, such as Epstein-Barr virus infection (EBV) or graft-versus-host disease (GvHD), have been reported. However, not every study conducted to date show this line of results.
