Special Issue Information

Dear Colleagues,

In recent years, many advances have been made in the understanding of the pathophysiology behind various hematological disorders. A better understanding of the molecular biology of both benign, such as hemoglobinopathies and congenital bleeding disorders, and malignant hematological diseases has led to the development of targeted therapeutics. For example, since the discovery of the Philadelphia chromosome in patients with chronic myelogenous leukemia and the development and approval of Imatinib, a tyrosine kinase inhibitor (TKI), the management of this clinical entity has been revolutionized. Moreover, the involvement of the immune system has been recognized in the pathogenesis of many hematological diseases. Specifically, complement system activation has been described as pathogenic in various disorders, such as paroxysmal nocturnal hemoglobinuria (PNH). Immune dysregulation is also prevalent in hematological malignancies, while immune therapeutics, including chimeric antigen receptor-T (CAR-T) cells and bispecific antibodies, constitute nowadays a standard of care for patients with refractory/relapsed B-cell lymphoproliferative neoplasms and multiple myeloma. The interaction between coagulation, immunity, and vascular endothelium is an emerging issue, concerning not only hematological disorders but also the complications of hematopoietic stem cell transplantation and novel immune therapeutics. This Special Issue aims to publish cutting-edge communication, research, and review articles concerning the pathophysiology, molecular biology, and novel therapeutics about, but not limited to, the following clinical entities: acute leukemia; myeloproliferative neoplasms; lymphoma; multiple myeloma; hemoglobinopathies; and hemophilia.

Notably, we also want to thank the journal’s Topical Advisory Panel Member, Dr. Nikolaos Kotsiou, for his contribution and support to the concept proposal, collaboration promotion, Special Issue operation, and development of this Special Issue.

Methotrexate (MTX) is an anti-folate chemotherapeutic agent that is considered to be a gold standard in Acute Lymphoblastic Leukemia (ALL) therapy. Nevertheless, toxicities induced mainly due to high doses of MTX are still a challenge for clinical practice. MTX pharmacogenetics implicate various genes as predictors of MTX toxicity, especially those that participate in MTX intake like solute carrier family 19 member 1 (SLC19A1). The aim of the present study was to evaluate the association between SLC19A1 polymorphisms and its regulatory miRNAs with MTX toxicity in children with ALL. A total of 86 children with ALL were included in this study and were all genotyped for rs2838958, rs1051266 and rs1131596 SLC19A1 polymorphisms as well as the rs56292801 polymorphism of miR-5189. Patients were followed up (48, 72 and 96 h) after treatment with MTX in order to evaluate the presence of MTX-associated adverse events. Our results indicate that there is a statistically significant correlation between the rs1131596 SLC19A1 polymorphism and the development of MTX-induced hepatotoxicity (p = 0.03), but there is no significant association between any of the studied polymorphisms and mucositis or other side effects, such as nausea, emesis, diarrhea, neutropenia, skin rash and infections. In addition, when genotype TT of rs1131596 and genotype AA of rs56292801 are both present in a patient then there is a higher risk of developing severe hepatotoxicity (p = 0.0104). Full article
