Filter by:The purpose of this observational study is to examine the rate at which elevated body temperature (fever) is relieved by an itraconazole injection administrated to patients experiencing neutropenic fever . A neutropenic fever is an elevated body temperature that occurs at a time when the patient's white blood cell count is low. White blood cells aid the body's normal defenses against infection, so a fever during this period might make it difficult for the patient to fight infections.
This is an initial study to determine if CXCR4 inhibitor AMD 3100 or plerixafor may be a potential treatment for neutropenia due to CXCR4 mutations, the myelokathexis or WHIM (warts, hypogammaglobulinemia, immunodeficiency and myelokathexis) syndrome. This is the initial study of this concept and will involve up to 6 patients to receive increasing doses of plerixafor administered subcutaneously or on an alternate day basis. It is unknown if these patients will be highly sensitive to a blockade of CXCR4 activity and release more white blood cells than normal volunteers or cancer patients given the same dose of this drug. Therefore doses will begin at a level 12 fold less than currently used to mobilize stem cells and will be increased stepwise to achieve an acceptable circulating level of neutrophils.
The purpose of this observational study is to investigate whether a sufficient concentration of itraconazole can influence disappearance of a fever (defeverscence) when intravenous (into the vein) itraconazole is administered for resolving unknown neutropenic fever of participants who are given itraconazole oral solution as a prophylaxis under general treatment conditions.
Background: - WHIMS (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis Syndrome) is caused by various genetic changes that increase the activity of the chemokine receptor, CXCR4. Excessive function of this receptor causes mature neutrophils (part of the white blood cells) to be retained within the bone marrow rather than being released to the blood and is one of the causes of severe inherited neutropenia (low white blood counts). In neutropenia, the body is less able to fight off infection. Patients with WHIMS usually are at risk for skin, soft tissue, sinus, and lung infections, which can result in loss of hearing, teeth, and lung function. - Current treatment for WHIMS consists of regular injections of a white blood cell growth stimulating medication called granulocyte colony stimulating factor (G-CSF), and supplemental immunoglobulin (antibody). These therapies are expensive, nonspecific, have significant side effects and toxicities, and do not fully correct all problems, especially warts and cancers related to human papillomavirus (HPV). - A drug called Mozobil has been approved for use in combination with G-CSF to increase the number of stem cells that can be collected prior to bone marrow transplantation. Mozobil may offer a specific and well-tolerated new treatment for WHIMS and other syndromes characterized by neutropenia. Objectives: - To evaluate whether Mozobil is safe and effective to treat neutropenia (low white blood cell count) in patients with WHIMS. - To determine an appropriate treatment dose of Mozobil, within currently approved dosage levels. Eligibility: - Individuals between 18 and 75 years of age who have been diagnosed with WHIMS and have a history of severe infections. Design: - Potential participants will undergo a screening with a medical history, physical examination, questionnaire, heart and lung function scans, and blood and urine samples. Tests will also be done for hepatitis B and C virus, and human immunodeficiency virus (HIV) that causes acquired immunodeficiency syndrome (AIDS), as well as to check neutrophil function. - Patients who are being treated with G-CSF will stop injections for 2 days before being admitted to the National Institutes of Health (NIH) Clinical Center. - Patients may participate in a Dose Escalation study and receive increasing doses of Mozobil over 5 days of treatment until their white blood cell count improves sufficiently or the maximum approved dose is reached. Blood samples will be taken regularly throughout the treatment process. Patients will then receive an additional dose of Mozobil at the maximum approved dose or the dose sufficient to cause improvement, before restarting the G-CSF injections. - Patients may also participate in a long-term Chronic Dosing study and receive Mozobil once or twice a day for up to a maximum of 60 months.
The purpose of this study is to evaluate the infection rate of leukemia patients who eat two different diets. Patients in the "raw" group will eat cooked food and the addition of raw fruits and vegetables. Patients in the "cooked" group will eat only cooked foods and this is the standard neutropenic diet with no fresh fruits or vegetables allowed. The primary objective of the study is to evaluate the infection rate of leukemia patients who eat two different diets. The secondary objectives will be the incidence of fever requiring intravenous antibiotics in each group and death rate.
The purpose of this study was to define and classify antibacterial agents used in Turkey for patients with febrile neutropenia.
The purpose of this study is to determine if maintaining a high hemoglobin level in children that underwent bone marrow transplant will accelerate the neutrophil recovery.
In this study the investigators aim to test if a procalcitonin (PCT) - guided strategy allows to reduce the antibiotic use in patients with febrile neutropenia hospitalized in a Brazilian tertiary university hospital, causing no harm.
Febrile neutropenia are microbiologically documented in only 30% of the cases, and almost exclusively by blood cultures. The reasons for this low documentation are likely multiple: (1) some of these fevers are of non-infectious origin. (2) The bacterial inoculum present in the blood may be low and consequently undetectable by conventional blood cultures. The primary objective of the study is to assess new blood culture procedures and technics, in order to improve the diagnostic yield of blood cultures during febrile neutropenic episodes.
This is a phase 3, randomized, double-blind, placebo-controlled multi-center study evaluating the efficacy of pegfilgrastim to reduce the incidence of febrile neutropenia (FN) in patients with newly diagnosed, locally-advanced or metastatic colorectal cancer receiving first-line treatment with bevacizumab and either 5-fluorouracil, Oxaliplatin, Leucovorin (FOLFOX) or 5-fluorouracil, Irinotecan, Leucovorin (FOLFIRI). This study will also investigate the effect of adding pegfilgrastim to bevacizumab and either FOLFOX or FOLFIRI by evaluating overall survival, progression-free survival, and overall response rate in each arm at regular intervals over a maximum of 60 months follow-up.
