Background: To minimize adverse events of peripheral blood stem cell (PBSC) collection in healthy donors, it is reasonable to limit the total dose of granulocyte colony-stimulating factor (G-CSF) and/or the number of apheresis days without decreasing of PBSCs yield. Therefore, we have started to collect G-CSF induced PBSCs on day 4 instead of on day 5. So, we retrospectively aimed to investigate the results of this 4-day G-CSF administration.

Objective: In this study, we aimed to obtain real-life data on the use of antimyeloma agents, which significantly increase overall survival (OS) in multiple myeloma (MM) patients, in primary plasma cell leukemia (pPCL) patients with poor prognosis.

Materials And Methods: Data from 53 patients who were diagnosed with pPCL between 2011 and 2020 and who used at least one proteasome inhibitor (PI) and/or immunomodulatory (IMID) agent were analyzed retrospectively. Depending on the year of the pPCL diagnosis, 20% leukocytes or ≥2x10/L plasma cells in the peripheral blood was used as a diagnostic criterion.

Background: A promising recent strategy for haploidentical transplantation is the depletion of T lymphocytes based on the selective elimination of T cells by manipulation, which enables a very low incidence of nonrelapse mortality and graft-vs-host disease. It is more expensive than conventional unmanipulated methods and requires dedicated transplant centers and sufficient stem cell processing facilities. This retrospective study aimed to evaluate the relapse, survival, and clinical data of the patients and to analyze the outcomes of the technique.

TEMPI syndrome was first defined in 2011 and classified as a plasma cell neoplasm with associated paraneoplastic syndrome in 2016. The pathogenesis of the syndrome is not well understood. Recognition of a combination of telangiectasia, erythrocytosis with a high erythropoietin level, monoclonal gammopathy, perinephric fluid collection, and intrapulmonary shunt is the first step in managing the disease.

Introduction: Idiopathic intracranial hypertension (IIH) (pseudotumor cerebri) is a rare side effect of all-trans retinoic acid (ATRA). IIH cases have been observed after the concomitant use of ATRA with azole group antimicrobials such as fluconazole and voriconazole. Here, we discuss about the diagnosis and treatment process of the IIH emerging in a young acute promyelocytic leukemia (APL) case with the ATRA impact, which can be increased by posaconazole.

Background: The molecular mechanism underlying the mobilization and engraftment of CD34+ cells is poorly understood. The most relevant factors in the regulation of stem cell release and engraftment include chemokines, adhesion molecules, and chemokine receptors. Previously, it was suggested that the absence of CD56 expression could be used as a predictive factor for mobilization failure at the time of diagnosis.

Article Synopsis
  • Paroxysmal nocturnal hemoglobinuria (PNH) is a complex genetic disorder that can lead to serious complications like blood clots, and recent studies show positive results from a treatment called eculizumab.
  • In a study of 138 PNH patients treated with eculizumab in Turkey from 2008 to 2018, common symptoms included fatigue and hemoglobinuria, with significant improvements in hemoglobin and lactate dehydrogenase levels noted after seven months of therapy.
  • The findings suggest that eculizumab is effective and well-tolerated, with minimal serious adverse events reported among the patients.

The AETHERA trial reported an increased progression-free survival (PFS) when brentuximab vedotin (BV) was used as maintenance therapy in high-risk Hodgkin lymphoma (HL) after autologous stem cell transplantation (ASCT). Thus, we aimed to determine the impact and safety of BV as maintenance after ASCT in real-world patients. Seventy-five patients with relapsed/refractory HL started on BV consolidation therapy after ASCT due to high risk of relapse, between January 2016 and July 2019, from 25 institutions, were included in the study.
