A Single Arm, Phase II Study of Eltrombopag to Enhance Platelet Count Recovery in Elderly Patients With Acute Myeloid Leukemia Undergoing Remission Induction Therapy

This phase II trial studies how well eltrombopag olamine works in improving the recovery of platelet counts in older patients with Acute Myeloid Leukemia (AML) undergoing induction (the first treatment given for a disease) chemotherapy. Platelet counts recover more slowly in older patients, leading to risk of complications and the delay of post-remission therapy. Eltrombopag olamine may cause the body to make platelets after chemotherapy.

Phase I Dose-Finding Study of Eltrombopag Following High Dose Cytarabine and Mitoxantrone in Relapsed/Refractory Patients With Acute Myeloid Leukemia

The purpose of this study is to find out the highest safe dose and examine the side effects and effectiveness of eltrombopag olamine in patients with acute myeloid leukemia (AML) treated with chemotherapy that have not responded to previous therapy or have suffered a relapse

A Phase I Study of Azacitidine Combined With Mitoxantrone and Etoposide (A-NOVE) Chemotherapy for Patients' Age ≥ 60 With Poor Prognosis Acute Myeloid Leukemia (AML)

This phase I trial studies the best dose of azacitidine and to see how well it works with mitoxantrone hydrochloride and etoposide in treating older patients with acute myeloid leukemia that has a lower chance of responding to treatment or higher risk of returning (poor prognosis). Drugs used in chemotherapy, such as azacitidine, mitoxantrone hydrochloride, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

A Case of Acute Eosinophilic Leukemia with a Novel PHF6 Mutation

作者: Huselton, E. J. ; Lipof, J. J. ; Zent, C. S. ; Rothberg, P. G. ; Zhang, B. ; Evans, A. ; Bennett, J. M.

Acute eosinophilic leukemia (AEL) is a rare form of acute myeloid leukemia (AML) that requires prompt exclusion of reactive etiologies of eosinophilia and identification of an underlying acute myeloid neoplasm. Myeloid neoplasms with prominent eosinophilia often have rearrangements in the platelet-derived growth factor receptor

α

(PDGFRA) or

β

(PDGFRB) or are associated with core-binding factor AML. In this report, we describe a 35-year-old male presenting with chest discomfort and altered mental status, found to have marked leukocytosis with eosinophilic predominance and an elevated blast count. Bone marrow aspirate and biopsy findings were morphologically consistent with AEL. Fluorescence in situ hybridization (FISH) and standard karyotype analysis did not reveal any abnormalities, and mutation analysis using next generation sequencing (NGS) revealed a pathogenic mutation in PHF6. Cardiac work-up revealed findings suggestive of eosinophilic myocarditis. High-dose glucocorticoid therapy was initiated followed by standard intensive induction chemotherapy with cytarabine and idarubicin. He experienced a rapid reduction in peripheral blood eosinophil and blast count and was found to be in a complete remission at the time of his postinduction bone marrow examination. He underwent allogeneic stem cell transplantation with a matched sibling donor after consolidative high-dose cytarabine and remains in remission at the time of this report, 6 months following his initial diagnosis. The rarity of this condition has resulted in a paucity of data to guide management. Additional studies are needed to better characterize this entity and inform optimal management strategies to attain a long-term sustained remission in these patients.

Receptor tyrosine kinase PDGFRα is often constitutively activated in various tumours and is regarded as a drug target. Here, we present a collection of 2,6,9-trisubstituted purines with nanomolar potency against PDGFRα and strong and selective cytotoxicity in the human eosinophilic leukaemia cell line EOL-1 that expresses the FIP1L1-PDGFRA oncogene. In treated EOL-1 cells, the example compound 14q inhibited the autophosphorylation of PDGFRα and the phosphorylation of STAT3 and ERK1/2. Interestingly, we observed pronounced and even increased effects of 14q on PDGFRα and some of its downstream signalling pathways after drug washout. In accordance with suppressed PDGFRα signalling, treated cells were arrested in the G1 phase of the cell cycle and eventually underwent apoptosis. Our results show that substituted purines can be used as specific modulators of eosinophilic leukaemia.

Eosinophilic infiltrate in a patient with severe Legionella pneumonia as a levofloxacin-related complication: a case report

Article

作者: Francesco Menzella ; Roberto Piro ; Nicola Facciolongo ; Claudia Castagnetti ; Alberto Cavazza ; Cristiano Carbonelli ; Luigi Zucchi

INTRODUCTIONLegionella pneumonia can appear with different levels of severity and it can often present with complications such as acute respiratory distress syndrome.CASE PRESENTATIONWe report the case of a 44-year-old Caucasian man with Legionella pneumonia with successive development of severe acute respiratory distress syndrome. During his stay in intensive care the clinical and radiological situation of the previously observed acute respiratory distress syndrome unexpectedly worsened due to acute pulmonary eosinophilic infiltrate of iatrogenic origin.CONCLUSIONLevofloxacin treatment caused the occurrence of acute eosinophilic infiltrate. Diagnosis was possible following bronchoscopic examination using bronchoaspirate and transbronchial biopsy.
