OBJECTIVE: HLA-DPB1 matching may impact allogeneic hematopoietic stem cell transplantation (ASCT) outcomes; however, this locus is not in linkage disequilibrium with the remainder of the HLA genes. After classifying HLA-DPB1 mismatches based on T-cell epitope, avoiding non-permissive mismatches may impact survival. We tested this hypothesis at a single academic institution. METHODS: Retrospective HLA-DPB1 genotyping was performed on 153 adult patients who underwent ASCT and unrelated donors matched for HLA-A, B, C, DRB1 and DQB1 loci (10/10)...

PURPOSE: FMS-like tyrosine kinase 3- internal tandem duplication (FLT3-ITD) is aberration associated with poor prognosis in AML. We have analyzed the expression of MDR-1, MRP-1 and BCRP mRNA in relation to FLT3-ITD in 100 AML adult patients with normal and intermediate karyotype. METHODS: The RQ-PCR method was performed to assess the expression of MDR-1, MRP-1 and BCRP mRNA and the results were presented as coefficients calculated using an intermediate method according to Pfaffl's rule...

OBJECTIVE: The aim of this study was to detect iron restriction in non-anaemic patients and iron-restricted erythropoiesis (IRE) in patients with anaemia. METHOD: Haematologic indices and biochemical markers of iron deficiency (ID) were determined using the clinically accepted cut-off level for serum ferritin of ≤30 μg/l as reference of ID. To evaluate the prevalence of iron restriction and IRE in patients with higher ferritin levels we used the thresholds of the markers of ID as reference...

OBJECTIVE: overexpression of ABCG2 and CD200 have been independently associated with poor outcome in acute myeloid leukemia (AML). However, no data are available on the role of these two factors in patients with core binding factor (CBF) positive or FLT3-negative / NPM1-mutated cytogenetically normal (CN) AML. METHODS: we analyzed 65 adult AML patients with CBF+ (n=16) or FLT3-/NPM1+ CN (n=49), evaluating clinical and biological factors associated with complete remission attainment, leukemia-free survival (LFS) and overall survival (OS)...

Chronic Lymphocytic Leukaemia (CLL) is a chronic B cell lympho-proliferative disorder in which lymphomatous transformations occur in 5-15% of patients. Histologically these cases resemble diffuse large B cell lymphoma, or Richter's transformation, in over 80% of cases. Rare cases of transformation to Hodgkin lymphoma (HL) have been reported in the literature with an estimated prevalence of 0.4%. We report a case of a 67 year-old female with CLL treated with the novel Bruton's tyrosine kinase (Btk) inhibitor, ibrutinib, who subsequently presented with intractable fevers...

BACKGROUND: The role of PAI-1 4G/5G polymorphism in venous thrombosis has been contradictory. PAI-1 4G/4G genotype is associated with elevated levels of PAI-1 resulting in a hypofibrinolytic state and a higher thrombotic risk. OBJECTIVE: In this study, the distribution of genotypes and frequency of alleles of the 4G/5G polymorphism of PAI-1 gene in Indian patients with different types of venous thrombosis was investigated for its role in development of thrombosis...

OBJECTIVES: Long non-coding RNAs (lncRNAs) are RNA transcripts longer than 200 nucleotides that are not translated into proteins. They are involved in pathogenesis of many diseases including cancer and have a potential to serve as diagnostic and prognostic markers. We aimed to investigate lncRNA expression profiles in bone marrow plasma cells of newly diagnosed multiple myeloma (MM) patients in comparison to normal bone marrow plasma cells of healthy donors (HD) in a 3-phase biomarker study...

Solitary plasmacytoma (SP) and Plasma cell leukemia (PCL) are uncommon (3-6%) types of plasma cell disease. The risk of progression to symptomatic multiple myeloma (MM) is probably important for the outcome of SP. PCL is rare and has a dismal outcome. In this study we report on incidence and survival in PCL/SP, and progression to MM in SP, using the prospective observational Swedish Multiple Myeloma Register designed to document all newly diagnosed plasma cell diseases in Sweden since 2008. Both solitary bone plasmacytoma (SBP), (n=124) and extramedullary plasmacytoma (EMP), (n=67) have better overall survival (OS) than MM (n=3549)...

We report on a multidisciplinary management of a 68-year-old AML patient presenting with a PET-positive mediastinal tumour typical for lymph node metastasis. It was removed via minimally invasive thoracoscopic intervention and was identified as a thymus residual infiltrated by AML. Follow-up PET-CT scan after resection and remission induction chemotherapy was completely normal. To our knowledge, this is the first documented case report of AML presenting with PET-positive infiltrates of thymic and lymph node tissue along the aortic bow mimicking a second intrathoracic malignancy...

Post-transplant lymphoproliferative disorders (PTLD) are a heterogeneous and potentially fatal group of neoplasms arising in an immunodeficient environment in the background of viral antigenic stimulation. PTLD is rare, with an incidence in solid organ transplant recipients typically less than 20% [1]. For aggressive, monomorphic cases, current guidelines recommend reduced immunosuppression in addition to chemoimmunotherapy, which generally consists of R-CHOP [1]. Nevertheless, prognosis is poor with 5-year overall survival (OS) rates of only 40-60% [1]...

OBJECTIVES: Heavily pretreated patients with relapsed and refractory multiple myeloma are susceptible to treatment-related adverse events (AEs). Managing AEs is important to ensure patients continue therapy long enough to receive the best clinical benefit. Data from the MM-002, MM-003, and MM-010 trials were pooled to further characterize the safety profile of pomalidomide plus low-dose dexamethasone and AE management. METHODS: This analysis included 1088 patients who received ≥ 2 prior therapies, including lenalidomide and bortezomib, and progressed ≤ 60 days of last therapy...

We present a case report of a patient relapsing after anti-CD38 treatment (daratumumab). The phenotype of the disease changed during this treatment, and the myeloma clone became CD38 negative and daratumumab refractory. We expected clonal shift, however, based on immunophenotyping, cytogenetics and arrayCGH; the clone was identical as before daratumumab-based treatment with the exception of CD38 negativity. We suggest that the downregulation or loss of CD38 might be an epigenetic "escape mechanism" of malignant plasma cells from antibody-based treatment...

OBJECTIVES: The etiology of multiple myeloma (MM) is unknown and it remains incurable. We sought to elucidate the mechanisms underlying miRNAs involvement in MM pathogenesis. METHODS: Public mRNA and miRNA expression datasets for MM were collected from the Gene Expression Omnibus database. By integrated bioinformatics analysis, the expression signatures were identified and the miRNA-mRNA interaction network was constructed. The potential functions of target genes were then explored by functional enrichment analysis...

The distinction of inherited bone marrow failure syndromes (IBMFS) from other acquired forms of aplastic anemia (AA) is very important for instituting proper therapy. However this is not often straight forward. A proper confirmatory genetic diagnosis is possible only in less than 50% of the patients even with the use of massive parallel sequencing (1). Moreover its application is still limited due to the cost and several logistical issues. Unfortunately, diethyl epoxy butane (DEB) or mitomycin C induced chromosome breakage studies (CBS) is the only test, which is widely employed, for the diagnosis of IBMFS in many resource-limited settings...

OBJECTIVES: CREBBP alterations are associated with many diseases including leukaemia. However, CREBBP expression and its clinical relevance in paediatric acute lymphoblastic leukaemia have not been elucidated. METHODS: We studied CREBBP mRNA expression in 349 patients treated with either the BCH-2003 or CCLG-2008 protocol. Using a receiver operating characteristic curve, patients were divided into low- or high-CREBBP. The association among clinicobiological characteristics, outcomes, and CREBBP level was analysed...
