Active clinical trials for "Febrile Neutropenia"

The purpose of this study is to see how different antibiotics affect the community of friendly bacteria existing in the intestinal tract (gut). Under normal circumstances, these friendly bacteria are not harmful and they help with normal bodily functions such as digestion. When these bacteria are absent, several complications may occur, such as infections with harmful bacteria or other inflammatory reactions, that can complicate the stem cell transplant course. Treatment with antibiotics or chemotherapy is known to kill off these friendly bacteria. In this study we compare the effects of different antibiotics on the community of friendly bacteria in the gut. For microbiota-related biomarker analysis, optional urine samples (MSKCC patients only) will be collected at baseline, 7 +/-2 days after initiation of antibiotic therapy, and on post-transplant days +28, +56 and +100 (+/- 7days).

This study aims to analyze the effects of long-acting granulocyte colony stimulating factor (G-CSF) on the prevention febrile neutropenia (FN) in epithelial ovarian cancer. Patients are randomized into study group and control group. In study group, patients accept long-acting G-CSF 48 hours from the chemotherapy. While the control group accept regular treatment rather than long-acting G-CSF. The primary end is the incidence of FN in every course of chemotherapy. The secondary ends include: the incidences of myelosuppression, doses of G-CSF and its expenses, visits to outpatient and emergency clinics, adverse events related to G-CSF.

In general, the percentage of complete remissions is 85 - 90 % for acute lymphoid leukemia (ALL). In developing countries, percentages are lower secondary to higher sepsis-related mortality. Although the effect of statins on inflammatory response associated with sepsis has been demonstrated, including an effect on bacterial proliferation in patients with a state of immunosuppression, their effect has not been demonstrated so far in patients with hemato-oncological cancer.

This is a comparative study for adult participants with cancer who are suspected to have neutropenic fever (or fever with low neutrophil count) in emergency department. Neutrophil is a kind of defensive white blood cell combating against infection, especially by bacteria and fungi. Low neutrophil can be part of the disease progress or secondary to some cancer treatment. These participants are at high risk of developing infection-related complications including death. Currently a dedicated clinical pathway has been in place in emergency department for suspected neutropenic fever, which offers fast-track medical consultation, blood tests and a very strong antibiotic (meropenem) as the first choice within 1 hour of registration. However, majority of such participants' neutrophil counts are not low. Most of them have no bacterial infection in the body, and have unremarkable short hospital stays. Early administration of meropenem in the majority of cases may be unnecessary and imposes risk of developing antibiotic resistance. This study attempts to answer the question, "In adult participants with cancer presenting to emergency department with suspected neutropenic fever, when compared with conventional treatment, can a new protocol guided by fast-track neutrophil count reduces prescription of meropenem?" Agreed participants will be randomly assigned to the conventional treatment group, or the new treatment group. For those who are assigned to the new treatment group, blood will be taken and sent to the hospital laboratory for urgent analysis of neutrophil count. Participants with proven low neutrophil counts will still receive meropenem, while those without low neutrophil counts will receive less strong antibiotic according to their clinical diagnoses, such as Augmentin. They will be followed up on the first 7 days, and then on the 14th, 30th, 90th, and 180th days after recruitment. Comparisons will be made to see how much less meropenem will be prescribed, and whether more serious adverse events will happen. The study is expected to take 37 months to complete. Duration of data collection, including the day of last follow up, is estimated to be 33 months.

This randomised controlled trial will determine the non-inferiority of stopping empiric antibiotics prior to absolute neutrophil count (ANC) recovery (Early Stopping) versus stopping antibiotics upon ANC recovery (Standard of Care/ Late Stopping) , in children with cancer and high-risk febrile neutropenia (FN).

This is a randomized study to evaluate the safety and feasibility of early de-escalation of empirical antibiotics treatment in neutropenic fever patients undergoing hematopoietic stem cell transplantation (HSCT). In case of afebrile for 72 hours with empirical antibiotics treatment, patients will be randomized into 2 groups. In the early de-escalation group, antibiotics treatment will be stopped and prophylaxis with levofloxacin will be resumed. In the control group, the empirical treatment will continue until recovery of neutropenia or at least for 7 days.

To demonstrate that the early addition of Pentaglobin to the best available antimicrobial therapy is able to reduce mortality and improve survival in neutropenic febrile acute leukemia or allo- Hematopoietic stem cell transplantation (HSCT) patients colonized by carbapenem-resistant Enterobacteriaceae or by any Pseudomonas aeruginosa.

Febrile aplasia is a common occurrence in children/adults treated with chemotherapy for malignant blood diseases or solid cancers. This acquired deficiency of immunity mainly causes susceptibility to bacterial and fungal infections, pathogens normally recognized by specific receptors of innate immunity (Pattern Recognition Receptor, PRR). Thus, the febrile episodes in the context of post-chemotherapy neutropenia can be bacterial or fungal etiology, but can also frequently be related to viral infections, toxic phenomena or other etiologies. In the absence of a discriminating marker, treatment for all these children is based on early, broad-spectrum antibiotic therapy in hospital. Septic shock or even death by refractory septic shock remain, even if they are rare, real complications in pediatric oncology, requiring discriminatory markers for effective management, While trying to reduce the number and duration of hospitalizations for children at low risk for severe febrile aplasia. It is therefore necessary to identify other markers allowing the earliest possible classification of episodes of febrile aplasia. A previous study, conducted by our team, PTX3 and febrile aplasia, studied pentraxin 3 (PTX3), a soluble PRR of the pentraxin family that plays a key role in immune surveillance against pathogens. Preliminary results obtained from samples from a cohort of patients treated in adult hematology and pediatric onco-hematology support a prognostic character of PTX3 in the severity of aplasia, with higher elevations of serum protein during episodes of severe sepsis or septic shock (ongoing analyses and interpretations for the adult population). The available data to date on the pediatric cohort are insufficient to conclude on the value of using PTX3. The investigators therefore wish to create a new paediatric cohort, in order to evaluate the PTX3 levels for the paediatric population and also to perform the assay of a new marker, clusterin. Clusterin (CLU) is an extracellular chaperone protein of constitutive expression. The Innate Immunity team of the National Institute of Health and Medical Research (INSERM) "1307-Scientific Research National Center (CNRS) 6075" unit has shown that Clu binds to extracellular histones and inhibits their inflammatory, thrombotic and cytotoxic properties. The investigators also observed (i) that in adults without severe sepsis neutropenics, low serum levels of Clu at intake and lack of normalization of rates are associated with higher mortality and (ii) Clu levels are inversely correlated with circulating histone levels. All these data suggest that Clu would have a protective role for histone-induced lesions during sepsis independently of antibiotic treatment, opening an innovative therapeutic pathway in the management of severe sepsis. CluPPFeN is based on the hypothesis that, in a pediatric population with episodes of febrile aplasia, serum Clu and serum PTX3 levels would discriminate between febrile episodes caused by bacterial infection and other etiologies and, As a result, would reduce the consumption of antibiotics, which provide resistance, and the length of hospitalization.

Randomized phase 3 trial to compare efficacy and safety of oral fosfomycin versus ciprofloxacin to prevent febrile neutropenia in patients with acute leukemia or recipients of hematopoietic stem cell transplant.

Febrile neutropenia (NF) is the leading cause of unscheduled hospitalization in children with cancer. Management classically involves emergency admission to hospital for intravenous antibiotic treatment until resolution of fever and neutropenia. However, children with NF are a heterogeneous group with varying risks of severe infection (10-29%). This approach, which is recognized as excessive for low-risk episodes of severe infection, particularly in terms of quality of life and cost, is no longer recommended. Management should move to a more personalized model that takes into account the individual probability of severe infection. Clinical decision rules (CDRs) have been proposed to facilitate risk stratification, but none are useful in our French population because of insufficient reproducibility or effectiveness.
