Pharmacokinetics of posaconazole prophylaxis of patients with acute myeloid leukemia.

Antifungal prophylaxis is routinely given to patients with hematologic malignancies at high risk for invasive fungal infections (IFI), yet breakthrough IFI may still occur. Posaconazole emerged as an excellent alternative for fungal prophylaxis in high-risk patients. There is limited data about pharmacokinetics and plasma concentrations of posaconazole when given as prophylaxis in patients with hematologic malignancies.

Phase II, open label, randomized comparative trial of ondansetron alone versus the combination of ondansetron and aprepitant for the prevention of nausea and vomiting in patients with hematologic malignancies receiving regimens containing high-dose cytarabine.

Background. Aprepitant is a P/neurokinin-1 receptor antagonist approved for the prevention of CINV in moderate emetic risk chemotherapy. We explored its effectiveness in patients with leukemia receiving cytarabine-based chemotherapy.

Epoetin alpha decreases the number of erythrocyte transfusions in patients with acute lymphoblastic leukemia, lymphoblastic lymphoma, and Burkitt leukemia/lymphoma: results of a randomized clinical trial.

Background: Anemia is an expected consequence of intensive chemotherapy regimens administered to patients with acute leukemia. This study was designed to determine whether epoetin alpha would decrease the number of transfusion events and units of packed erythrocytes (PRBCs) transfused, and the secondary objective was to study the effects of epoetin alpha on quality of life (QOL) and complete remission (CR) rates.

Methods: Patients with acute lymphoblastic leukemia (ALL), lymphoblastic lymphoma (LL), or Burkitt lymphoma (BL) who were receiving frontline myelosuppressive chemotherapy were randomized to receive epoetin alpha or no epoetin during the first 6 cycles of their planned chemotherapy.

Daily palonosetron is superior to ondansetron in the prevention of delayed chemotherapy-induced nausea and vomiting in patients with acute myelogenous leukemia.

Background: Nausea and vomiting in patients with acute myelogenous leukemia (AML) can be from various causes, including the use of high-dose cytarabine.

Methods: The authors compared 2 schedules of palonosetron versus ondansetron in the treatment of chemotherapy-induced nausea and vomiting (CINV) in patients with AML receiving high-dose cytarabine. Patients were randomized to: 1) ondansetron, 8 mg intravenously (IV), followed by 24 mg continuous infusion 30 minutes before high-dose cytarabine and until 12 hours after the high-dose cytarabine infusion ended; 2) palonosetron, 0.

Long-term prognostic impact of the use of erythropoietic-stimulating agents in patients with chronic myeloid leukemia in chronic phase treated with imatinib.

Background: Anemia is a frequent side effect of imatinib in patients with chronic myeloid leukemia (CML). Erythropoietic-stimulating agents have been used for treatment of imatinib-induced anemia. There are no data on long-term safety of erythropoietic-stimulating agents in CML patients.

Drug-induced nephrotoxicity caused by amphotericin B lipid complex and liposomal amphotericin B: a review and meta-analysis.

Lipid preparations of amphotericin B, commonly used to treat fungal infections, have been demonstrated to have reduced nephrotoxicity compared to conventional amphotericin B. However, to our knowledge, a comprehensive comparison of nephrotoxicity induced by different lipid preparations of amphotericin B has not been performed. We conducted a meta-analysis to evaluate nephrotoxicity associated with amphotericin B lipid complex (ABLC) and liposomal amphotericin B (L-AmB).

Predictors and outcome of acute kidney injury in patients with acute myelogenous leukemia or high-risk myelodysplastic syndrome.

Background: : Acute kidney injury (AKIis a common complication in the treatment of patients with acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (HR-MDS), but, to the authors' knowledge, its clinical relevance has not been detailed to date. The objective of the current study was to identify the incidence, predictors, and outcome for AKI in patients with AML and HR-MDS.

Methods: : Data were analyzed from 537 patients with AML or HR-MDS undergoing induction chemotherapy from 1999 to 2007.

Mycotic pulmonary artery aneurysm due to Aspergillus infection in a patient with leukemia: case report and review of the literature.

Acute pulmonary failure during remission induction chemotherapy in adults with acute myeloid leukemia or high-risk myelodysplastic syndrome.

Background: Acute pulmonary failure during remission induction therapy is a serious complication in patients with acute myeloid leukemia (AML). To the authors' knowledge, the course and prognosis of such patients is not well known.

Methods: A total of 1541 patients referred for remission induction chemotherapy of AML or high-risk myelodysplastic syndrome were retrospectively reviewed.

Diagnosis and antimicrobial therapy of lung infiltrates in febrile neutropenic patients: Guidelines of the infectious diseases working party of the German Society of Haematology and Oncology.

Patients with neutropenia lasting for more than 10d, who develop fever and pulmonary infiltrates, are at risk of treatment failure under conventional broad-spectrum antibacterial therapy. Filamentous fungi are predominant causes of failure, however, multi-resistant gram-negative rods such as Pseudomonas aeruginosa or Stenotrophomonas maltophilia may be involved. Prompt addition of mould-active systemic antifungal therapy, facilitated by early thoracic computed tomography, improves clinical outcome.

Randomized comparison of cooked and noncooked diets in patients undergoing remission induction therapy for acute myeloid leukemia.

Purpose: A neutropenic diet is often used to prevent infection in patients with acute myeloid leukemia (AML). Although such a diet potentially entails inconvenience, its value is uncertain.

Patients And Methods: One hundred fifty-three patients admitted to a high-efficiency particulate air-filtered room (protected environment [PE]) to receive induction therapy for newly diagnosed AML were randomly assigned to a diet containing no raw fruits or vegetables (cooked diet) or to a diet containing fresh fruit and fresh vegetables (raw diet).

Characteristics and outcome of respiratory syncytial virus infection in patients with leukemia.

Background And Objectives: Little is known about respiratory syncytial virus (RSV) infection in patients with leukemia. The aim of this study was to determine the characteristics, and the outcome of RSV infection with or without therapy with aerosolized ribavirin in leukemia patients.

Design And Methods: We reviewed the records of 52 leukemia patients with RSV infection seen at our institution between October 2000 and March 2005.

Neuraminidase inhibitors improve outcome of patients with leukemia and influenza: an observational study.

We reviewed the records of 33 patients with leukemia who experienced influenza during the period from October 2000 to March 2004. Three (38%) of the 8 patients who did not receive neuraminidase inhibitor therapy and none of the 25 patients who received it died of influenza pneumonia (P=.001).

Open-label, randomized comparison of itraconazole versus caspofungin for prophylaxis in patients with hematologic malignancies.

Invasive fungal infection remains the most common cause of infectious death in acute leukemia. In this open-label, randomized study, we compared the efficacy and safety of caspofungin with that of intravenous itraconazole for antifungal prophylaxis in patients undergoing induction chemotherapy for acute myelogenous leukemia or myelodysplastic syndrome. Of 200 patients, 192 were evaluable for efficacy (86 for itraconazole, 106 for caspofungin).

Management of intracranial fungal infections in patients with haematological malignancies.

The incidence of, and mortality associated with, invasive fungal infections remains far higher than hoped. As a consequence of the overall increase in the incidence of such infections over time, the incidence of central nervous system (CNS) fungal infections is also increasing and, despite improvements in diagnostic techniques and the introduction of novel antifungal agents, therapy for CNS infections is still associated with discouragingly poor results. In patients with haematological malignancies, opportunistic infections with Candida or Aspergillus remain the most common infections affecting the CNS; however, opportunistic infections with less well-known fungi are becoming more common and must be considered in the differential diagnosis.

Adaptive randomized study of idarubicin and cytarabine alone or with interleukin-11 as induction therapy in patients aged 50 or above with acute myeloid leukemia or high-risk myelodysplastic syndromes.

A higher complete remission (CR) rate was observed in patients with acute myeloid leukemia (AML) who, on a prior randomized study of induction therapy, received gemtuzumab ozogamicin (GO) plus interleukin-11 (IL-11) rather than GO alone. An adaptive randomized phase III study of the addition of IL-11 to idarubicin and cytarabine (IA) induction in 100 patients >/=50 years of age with AML or high-risk myelodysplastic syndrome (MDS) was conducted. Median patient age was 67 years (range 50-82).

Beta-D-glucan as a diagnostic adjunct for invasive fungal infections: validation, cutoff development, and performance in patients with acute myelogenous leukemia and myelodysplastic syndrome.

The Glucatell (1-->3)- beta-D-glucan (BG) detection assay (Associates of Cape Cod) was studied as a diagnostic adjunct for invasive fungal infections (IFIs). On the basis of findings from a preliminary study of 30 candidemic subjects and 30 healthy adults, a serum BG level of >or=60 pg/mL was chosen as the cutoff. Testing was performed with serial serum samples obtained from 283 subjects with acute myeloid leukemia or myelodysplastic syndrome who were receiving antifungal prophylaxis.

Amphotericin B lipid complex as prophylaxis of invasive fungal infections in patients with acute myelogenous leukemia and myelodysplastic syndrome undergoing induction chemotherapy.

Background: The optimal antifungal prophylactic regimen for patients with acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (MDS) undergoing induction chemotherapy has yet to be identified. A prospective historical control study evaluated the efficacy and safety of amphotericin B lipid complex (ABLC) in this patient population.

Methods: Newly diagnosed patients with AML or high-risk MDS who were undergoing induction chemotherapy received prophylactic ABLC 2.
