The Spectrum of MYC Alterations in Diffuse Large B-Cell Lymphoma.

MYC, as a powerful transcription factor, plays a vital role in various cancers. The clinical significance of MYC alterations in diffuse large B-cell lymphoma (DLBCL) has been investigated for a long time. In this study, we comprehensively summarize the different alterations of MYC in DLBCL, including MYC overexpression, MYC translocations, MYC mutations, and increased gene copy number of MYC. Noteworthy, lone MYC overexpression or MYC translocation is not significantly associated with poor clinical outcomes...

Treatment of Persons with Multiple Myeloma in Underprivileged Circumstances: Real-World Data from a Single Institution.

The treatment of patients with multiple myeloma (MM) has evolved in recent years, and the disease-associated prognosis has improved substantially. This improvement has been driven largely by the approval of novel agents, many of which are expensive and not universally available. Less expensive but effective approaches would be of value globally.

Combined Congenital Hypodysfibrinogemia and Factor XI Deficiency in a Chinese Family.

Both congenital hypodysfibrinogenemia and factor XI deficiency are rare coagulopathies caused by mutations within the fibrinogen and F11 genes, respectively. To investigate the pathogenesis of combined congenital hypodysfibrinogenemia with factor XI (FXI) deficiency in a Chinese family, coagulation assays, FXI activity (the 1-stage method), fibrinogen activity (the Clauss method), and antigen (prothrombin time [PT]-derived method) were performed. The sequences of fibrinogen genes and F11 were amplified by P...

Coexistence of Pure Red Cell Aplasia and Autoimmune Haemolytic Anaemia Associated with Thymoma.

Thymoma is an uncommon neoplasia derived from the epithelial cells of the thymus, which leads to immune dysregulation and is associated with a series of autoimmune diseases. However, the concurrence of these disease entities is rare, and the exact mechanisms of these diseases are still unclear. We have admitted several cases who were diagnosed with thymoma, autoimmune haemolytic anaemia, and pure red cell aplasia. These cases were the first to report the concurrence of these three disorders. After thymectom...

Alpha-Thalassemia Carrier due to -α3.7 Deletion: Not So Silent.

Alpha-thalassemia is one of the most prevalent genetic diseases, with the -α3.7 deletion being the most common mutation. Molecular studies have suggested mechanisms to explain the mild phenotype of "silent carrier" heterozygotes. However, the correlation between the clinical laboratory picture and the -α3.7 heterozygous state remains unclear, thus we chose to investigate.

Impact of Platelet Counts, Surgical Methods, and Preoperative Platelet Transfusion on the Outcome of Splenectomy for Immune Thrombocytopenia.

Splenectomy is an important and potentially curative treatment for immune thrombocytopenia (ITP). Laparoscopic splenectomy (LS) has replaced open splenectomy (OS) as the standard approach. The prognostic role of platelet count and the clinical indication of preoperative platelet transfusion are not entirely clear.

Rapid Complete Response to Single-Agent Bcl-2 Inhibitor Venetoclax in a Heart-Transplanted Patient with Triple Refractory Immunoglobulin Light-Chain Amyloidosis.

Immunoglobulin light-chain amyloidosis (AL) is a disease with limited treatment options due to the frailty of patients caused by organ damage. Since the clonal plasma cells often contain the cytogenetic aberration t(11;14), the Bcl-2 inhibitor venetoclax is suggested to have a role in the treatment of AL. Here, we report of a heart-transplanted patient, refractory to multiple therapies, reaching a rapid complete response with single-agent venetoclax.

Avoiding the Thorns of the Gifted Red Rose: Case Report of Late Diagnosis of Polycythemia Rubra Vera in a Sibling Bone Marrow Transplantation Donor for a Patient with Chronic Myeloid Leukemia.

Hemophilia A in Females: Considerations for Clinical Management.

Approximately 50% of female carriers of hemophilia A have factor VIII (FVIII) levels below 0.5 IU/dL and may be categorized as having mild hemophilia. Females with hemophilia may go undiagnosed for years because the most common symptoms - menorrhagia and bleeding after childbirth - also occur in females without hemophilia. Females with hemophilia can exhibit increased bleeding tendencies despite current guidelines of expected, adequate FVIII levels. The cases described illustrate the clinical variability an...

Risk Factors for Acute Kidney Injury and Chronic Kidney Disease following Allogeneic Hematopoietic Stem Cell Transplantation for Hematopoietic Malignancies.

Acute kidney injury (AKI) and chronic kidney disease (CKD) are considered common complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Extended Follow-up of an Educational Intervention Encouraging Appropriate Use of Blood Transfusions.

A restrictive transfusion strategy of packed red blood cells (PRBCs) has been associated with at least non-inferior patient outcomes in a variety of clinical settings. In December 2014, we conducted an educational intervention which consisted of an oral presentation and computerized notifications at a single tertiary medical center.

A Retrospective Study of the Combination of Rituximab, Cyclophosphamide and Dexamethasone for the Treatment of Relapsed/Refractory Warm Antibody Autoimmune Hemolytic Anemia.

The combination of rituximab, cyclophosphamide, and dexamethasone (RCD) is highly effective in the treatment of warm autoimmune hemolytic anemia (WAIHA) associated with chronic lymphocytic leukemia (CLL). We treated a cohort of patients with relapsed/refractory WAIHA, without CLL, with RCD. The primary objective was to evaluate the overall response (OR) of RCD therapy. Complete response (CR) was defined as a hemoglobin (Hgb) ≥12 g/dL. Partial response (PR) was defined as Hgb 10-11.9 g/dL or ≥2 g/dL incr...

Evaluation of N8-GP Activity Using a One-Stage Clotting Assay: A Single-Center Experience.

N8-GP (ESPEROCT®; turoctocog alfa pegol; Novo Nordisk A/S, Bagsvaerd, Denmark) is an extended half-life recombinant factor VIII (FVIII) molecule. FVIII-deficient plasma spiked with N8-GP can be accurately measured using many activated partial thromboplastin time (aPTT)-based one-stage clotting assay reagents with normal human plasma calibrators. To date, there are few data on the measurement accuracy of samples from patients treated with N8-GP. Here, we measure patient samples during routine treatment moni...

Prothrombin Complex Concentrate before Urgent Surgery in Patients Treated with Rivaroxaban and Apixaban.

Patients treated with direct Xa inhibitors may require urgent surgery. Administration of prothrombin complex concentrate (PCC) in this setting is common; however, it is based on limited experience in healthy volunteers.

Multi-Organ Failure as the Initial Presentation of Lymphocyte-Depleted Hodgkin Lymphoma in Two Patients with Human Immunodeficiency Virus.

Patients with HIV-associated lymphocyte-depleted Hodgkin lymphoma (HIV-HL) often present with advanced, extranodal disease and aggressive clinical features, limiting definitive therapeutic intervention. Here we report two patients with HIV-HL who presented with multi-organ dysfunction as an initial manifestation of their malignancy. Both were initially treated with brentuximab vedotin (BV), which led only to a temporary partial response, highlighting the challenges of treatment. One patient was eventually s...

Central Nervous System Complications after Allogeneic Hematopoietic Stem Cell Transplantation in Children.

Central nervous system complications (CNSCs) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are common and may be a significant source of morbidity and mortality. We performed a retrospective study of 153 pediatric patients who underwent allo-HSCT to determine CNSC type, incidence, and impact on survival. A total of 34 patients (22.2%) developed CNSCs. The cumulative incidence of CNSCs at 100 days and 3 years was 18.30 and 22.73%, respectively. The most common CNSC was calcineurin inhi...

Can Less Intensive Chemotherapy and an Autotransplant Cure Adult T-Cell Acute Lymphoblastic Leukemia?

T-cell acute lymphoblastic leukemia (T-ALL) is a rare disease usually treated with intensive, high-dose consolidation chemotherapy followed by an allotransplant in a substantial number of patients. The data of the RALL-2009 study on 125 adult T-ALL patients suggest that similar total chemotherapy doses given less intensively over a longer interval without interruptions and with an auto- rather than an allotransplant produce outcomes like current more intensive protocols and an allotransplant: 9-year cumulat...

High Expression Levels of Long Noncoding RNA Small Nucleolar RNA Host Gene 18 and Semaphorin 5A Indicate Poor Prognosis in Multiple Myeloma.

The aim of this study was to detect the expression of long noncoding RNA small nucleolar RNA host gene 18 (SNHG18) andsemaphorin 5A (SEMA5A) genes in multiple myeloma (MM) patients and to explore the correlation of the expression of these genes with the clinical characteristics and prognosis of MM patients.

Ponatinib in the Treatment of Chronic Myeloid Leukemia and Philadelphia Chromosome-Positive Acute Leukemia: Recommendations of a German Expert Consensus Panel with Focus on Cardiovascular Management.

Treatment of chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute leukemia (Ph+ ALL) has been revolutionized with the advent of tyrosine kinase inhibitors (TKIs). Most patients with CML achieve long-term survival similar to individuals without CML due to treatment with TKIs not only in frontline but also in further lines of therapy. The third-generation TKI ponatinib has demonstrated efficacy in patients with refractory CML and Ph+ ALL. Ponatinib is currently the most potent TKI in this...
