Publication date: Available online 30 June 2018Source: Clinical Lymphoma Myeloma and LeukemiaAuthor(s): Alan K. BurnettAbstractOlder patients with acute myeloid leukemia represent at least one half of those with the disease for whom randomized clinical trials of new treatments are in development. These patients represent an appropriate population in which to evaluate new treatments against the current standards of care, which could be azacitidine, decitabine, or low-dose cytarabine. However, despite the identification of treatments that can deliver a worthwhile increase in remission, none has yet delivered a survival super…

Abstract
At present, acute promyelocytic leukemia (APL) is the most curable form of acute myeloid leukemia and can be treated using all-trans retinoic acid and arsenic trioxide. However, the current treatment of APL is associated with some issues such as drug toxicity, resistance and relapse. Therefore, other strategies are necessary for APL treatment. In the present study, we investigated the effects of salinomycin (SAL) on APL cell lines NB4 and HL-60 and determined its possible mechanisms. We observed that SAL inhibite…

Conclusion: Together with changes in the expression/function of receptors targeted by TKIs, the expression of plasma membrane transporters involved in sorafenib uptake/efflux may affect the response of leukemia cells to this drug.

Application of next-generation sequencing (NGS) panels is usually limited to diagnosis, prognosis, and development of personalized treatment strategies/targeted therapies for patients with myeloid malignancies e.g., Myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPN), and acute myelogenous leukemia (AML). Here we present a case of 3 year old male that presented with pancytopenia and splenomegaly. His initial bone marrow revealed mild to moderate fibrosis (normocellular; no increase in blasts).

Acute myeloid leukemia (AML) is grouped in multiple subtypes based on recurrent genomic abnormalities with diagnostic and prognostic significance. To enhance our diagnostic approach, we developed a clinical whole-genome mate pair-sequencing (MPseq) assay to detect structural rearrangements and copy number changes. DNA is processed using Illumina Nextera MP library kit, sequenced and aligned to the reference genome using BIMA. Abnormalities are visualized using Mayo-developed Ingenium software using AML-panel restricting analysis to classic-AML rearrangements: ABL1, BCR, CBFB, CREBBP, DEK, KAT6A, MECOM, MLF1, MLL(KMT2A), MY…

Downing, Mondira Kundu, Stanley B. PoundsAbstractEvaluating the differential expression of a set of genes belonging to a common biological process or ontology has proven to be a very useful tool for biological discovery. However, existing gene-set association methods are limited to applications that evaluate differential expression across k⩾2 treatment groups or biological categories. This limitation precludes researchers from…

Cryptococcal antigen was useful for diagnosis. Although itraconazole was ineffective in protecting against trichosporonosis, treatment was successful with voriconazole following liposomal amphotericin B.

Gari-ToussaintAbstractEndophthalmitis is a rare infection of the vitreous and/or aqueous. It can be bacterial or fungal. Exogenous endophthalmitis is the most common form and results from direct inoculation of a pathogen after eye surgery or penetrating trauma. Endophthalmitis can also be endogenous, secondary to disseminated infection. Fungal endophthalmitis is associated with poor prognosis and treatment is difficult given the low penetration of most of the …

We report a myelodysplastic syndrome (MDS) patient who presented Fusarium solani infection associated with granulocytic sarcoma as an initial presentation of acute myeloid leukemia (AML) transformation. We performed histological examination, immunohistochemistry analysis, culture of the biopsy tissue and DNA sequencing to make a conclusive diagnosis of F. solani and granulocytic sarcoma, reinforcing the necessity of performing complete evaluation of skin lesions in immunocompromised patients.

In cancer, the anomalous transcriptome includes deregulated expression of non-coding RNAs in conjunction with protein-coding mRNAs in human genome. The coding or non-coding RNA transc…
