Transfusion in Transplantation

Hematopoietic stem cell transplantation is increasingly performed in several diseases; majority of them are hematologic malignancies. Hematopoietic stem cell transplantation is not an instant procedure; contrarily, its unique clinical and laboratorial consequences may take life‐long time. Blood product transfusion is an inevitable and critical component for the management. Hematopoietic stem cell transplant patients have different requirements regarding blood products transfusion because of their immune status, long‐term cytopenias and especially HLA and ABO incompatibilities. Health‐care staff who take a part in the management of those patients should be aware of specific and specialized transfusion requirements

Consolidation: Autologous Stem Cell Transplantation in Acute Leukemia

The goal of complete remission (CR) in acute leukemias could be achieved with intensive induction chemotherapy however patients need post remission consolidation strategies such as high-dose chemotherapy, or autologous (ASCT) or allogeneic (allo-SCT) hematopoetic stem cell transplantation for durable response. However, Allo-SCT is getting more attention in last decades because of improvements of conditioning regimens and graft versus host disease (GVHD) prohylaxis strategies and alternatively available donor sources, it is not suitable for all leukemia patients. The patients who would benefit from Allo-SCT or ASCT could be defined more easily by using risk stratification systems and minimal residual disease (MRD) monitoring. ASCT is considered a treatment option even if its use is declining in the world. Herein, we tried to summarize the studies that report the outcomes of ASCT in acute myeloid leukemia (AML) and acute, lymphoblastic leukemia and describe the patients who would be good candidate for ASCT

A comparison of ESHAP with R-ESHAP chemotherapy regimen as mobilizing regimen in Hodgkin lymphoma and non-Hodgkin lymphoma patients

AMAÇ: Geçtiğimiz yıllarda lenfomaların tedavisinde büyük ilerleme gerçekleştirilmiştir. CD20 pozitif non-Hodgkin lenfomaların tedavisinde Rituksimab altın standart olmuştur. Mobilizasyon üzerine olan etkileri üzerine yeterli çalışma yapılmamıştır. YÖNTEMLER: 11 yıllık sürede ESHAP veya R-ESHAP ile mobilize edilmiş 84 Hodgkin lenfoma ve non-Hodgkin lenfoma hastasını değerlendirdik. BULGULAR: R-ESHAP rejiminin istatistiksel olarak ESHAP rejiminden daha az etkili olmadığını bulduk. SONUÇ: Aferez öncesi düşük trombosit sayısının oluşturduğu olumsuz etkiyi ESHAP rejimine rituksimab eklenmesi ortadan kaldırabilir. OBJECTIVE: In recent years great advance has been succeeded in therapy of lymphomas. Rituximab has become a gold standard of CD20 positive non-Hodgkin lymphomas. Its effects on mobilization have not been studied sufficiently. METHODS: We evaluated 84 Hodgkin lymphoma and non-Hodgkin lymphoma patients who were mobilized with ESHAP or R-ESHAP chemotherapy regimens in 11 years. RESULTS: We found out that R-ESHAP regimen was not significantly inferior to ESHAP regimen. CONCLUSION: Rituximab addition to ESHAP regimen may overcome negative effects of low platelet counts before aphaeresi

A case series of CML patients who were presented with isolated thrombocytosis

Per WHO 2016 and 2022 (5th ed.) myeloproliferative disease guidelines, Chronic Myeloid Leukemia (CML) is classified under two major groups according to the presence of bcr-abl translocation; these groups require different treatment approaches and show clinical presentation heterogeneity. Treatment agents such as tyrosine kinase inhibitors (Imatinib, Dasatinib, Nilotinib, Bosutinib, Ponatinib, Radotinib), Omacetaxine and Asciminib have been used in the treatment of Bcr abl positive CML according to the patient's clinic and mutation status. According to the IRIS study, a study evaluating CML patients treatment response to imatinib, the major molecular response was 33.3% at 3 months, the major molecular response was 48% at 6 months, and the major molecular response was 62.1% at 12 months; furthermore, the rate of achieving a complete molecular response at 12 months was 94.9% (4). In patients who was treated with imatinib as first line therapy, the rate of transformation to accelerated or blastic phase at 18 months was 0.9% in the MMR group and 9.9% in the non-MMR group. In "conventional" CML patients, high leukocyte counts may be accompanied by thrombocytosis; though presentation with only thrombocytosis without leukocytosis is hardly described so far. In this poster presentation, we introduced 7 cases who initially presented with isolated thrombocytosis and then diagnosed with Ph(+) CML. This study was conducted in three adult hematology centers from Antalya, Izmir and Istanbul. 400 patients followed in these centers were reviewed retrospectively; seven patients presented with isolated thrombocytosis were identified. Demographic characteristics, diagnostic findings, and risk scores of these patients were evaluated (Tablo 1). Eln 2013 response criteria were used for evaluation of response for 3rd, 6th, 12th. monthly responses (Figure 1). Here we present 7 CML patients without leukocytosis who were diagnosed with marked thrombocytosis. The patients had similar symptoms and physical examination with no obvious splenomegaly or thrombosis. All of the patients had minimal basophilia and normal peripheral smear findings. All patients responded well to imatinib therapy. During follow up patients who maintained their MMR achieve had a better clinical course and prognosis compared to other CML patients
