Abstract
INTRODUCTION Peripheral blood stem cell (PBSC) collection via apheresis requires the administration of granulocyte colony-stimulating factor (filgrastim) to stem cell donors. Several reports have shown that filgrastim administration and apheresis procedure induce a hypercoagulable state across PBSC collection, which might predispose certain donors to thrombotic complications. METHODS We evaluated the hemostatic functions of healthy allogeneic stem cell donors by rotational thromboelastometry (ROTEM). Blood samples from healthy donors (n = 30) were collected at defined time points: before filgrastim (baseline), on the day of apheresis before and after the procedure, and 1 week after apheresis. RESULTS The results indicated that hemostatic changes are temporary since all parameters in both EXTEM and INTEM assays are restored to their initial values 1 week after the apheresis. CONCLUSION We concluded that stem cell apheresis does not induce a hypercoagulable state in healthy donors. This is the first study evaluating the hemostatic functions of stem cell donors by ROTEM.

Abstract
BACKGROUND Although plateletpheresis donation is commonly accepted as a safe procedure, its influence on platelet function, coagulation system and fibrinolysis is not completely elucidated. OBJECTIVES In this study, we tried to assess the effects of plateletpheresis on donor's hemostasis system by measuring platelet activation, development of platelet-leukocyte aggregates, and coagulation activation. STUDY DESIGN Prospective observational study. METHODS We used flow cytometry to determine the levels of platelet-monocyte complexes (PMC) and platelet-neutrophil complexes (PNC). sP-selectin and prothrombin fragment (PF) 1 + 2 values were determined by ELISA. RESULTS The PMC levels increased significantly seven days after apheresis in comparison with just after apheresis and 24 h after apheresis (p < 0.05). The PNC levels increased significantly seven days after apheresis compared to immediately after apheresis (p < 0.05). sP-selectin values decreased significantly immediately after apheresis (p < 0.05). While sP-selectin values increased seven days after apheresis in comparison with immediately after apheresis and 24 h after apheresis, but there were not statistically significant differences for sP-selectin levels (p > 0.05). PF1 + 2 levels decreased significantly immediately after apheresis compared to pre-apheresis (p < 0.05) and increased 24 h after apheresis and seven days after apheresis, but these differences were not statistically significant. CONCLUSION We concluded that plateletpheresis affects platelet activation but does not cause any change in coagulation activation.

Abstract
BACKGROUND Essential thrombocythemia is one of the chronic myeloproliferative neoplasms characterized by clonal proliferation of myeloid cells with variable morphological maturation and hematopoietic activity.It is characterized by excessive clonal platelet production with a tendency to thrombosis and bleeding. Thrombocytapheresıs is the removal of platelets by apheresis techniques. Thrombocytapheresıs is generally recommended in patients with essential thrombocythemia with acute, severe thrombotic or hemorrhagic events. METHODS The study included 39 patients who were diagnosed with essential thrombocythemia, started cytoreductive and aspirin therapy, and underwent thrombocytapheresıs due to the development of acute severe thrombotic or hemorrhagic events, diagnosed in the adult hematology clinic of İnönü University Turgut Ozal Medical Center. Hemogram and biochemistry values of the patients were scanned retrospectively. RESULTS After thrombocytapheresıs, a statistically significant difference was found between the first and last measurements of hemoglobin, mean platelet volume, White blood cell, neutrophil, platelet, platelet distribution width, creatine, lactate dehydrogenase, fibronogen and calcium levels of the patients. CONCLUSION The use of thrombocytapheresıs in patients with essential thrombocytosis causes a rapid decrease in platelet values as well as an effect on hemogram and biochemistry parameters. Other hemogram and biochemistry parameters such as platelet value should be monitored in patients.

Abstract
INTRODUCTION The aim of this study was to evaluate and compare two different apheresis and changes in some immunological factors in donors. MATERIAL AND METHODS The cross-sectional study was performed from January 2017 to September 2018. Fifty six male blood donors were randomly divided into two groups. CD4, CD8, and CD25 markers by flow cytometry, and TGFBeta by real-time polymerase chain reaction (RT-PCR) method were done before and 7 days after the apheresis procedure. Independent Sample t-test, Mann-Whitney U Test, Wilcoxon signed ranked test, and Fisher exact test were used. RESULTS WBC in MCS+ group after donation is significantly higher than before donation (P < 0.05) but no significant difference was seen between MCS+ and Trima groups in these two indicators. But in CD4, CD25, and TGFBeta, there was no significant difference between the two groups. CONCLUSION There was no significant difference on CD4, CD25, and TGFBeta gene 7 days after donation.

Abstract
Hemostasis is a complex dynamic process involving bleeding and thrombosis as two end-points. Conventional coagulation tests which are measured in plasma examine only isolated portions of the coagulation cascade, thereby giving no information on important interactions essential to the clinical evaluation of hemostatic function. Thromboelastography (TEG), originally described in 1948 has improved over the decades and become a valuable tool of coagulation testing because of the limitations of standard coagulation tests. TEG is a technique that provides data about the entire coagulation system, from the beginning of clot formation to fibrinolysis, involving both cellular and plasma components of hemostasis. Rotational thromboelastometry (ROTEM) which evolved from TEG technology overcome several limitations of classical TEG while maintaining a good correlation with conventional TEG determination. ROTEM analyses are useful for rapid assessment of global clotting function in various clinical situations including liver transplantation, cardiac surgery, obstetrics, trauma, hemophilia and idiopathic thrombocytopenic purpura. ROTEM has been also reported to be useful in identifying various hypercoagulable conditions including major surgery, malignancy, Behcet’s disease and apheresis. Further developments in ROTEM based transfusion strategies may also reduce transfusion requirements and improve clinical outcomes by optimizing the administration of blood components. This is a literature review of ROTEM including its technique, interpretation and specially clinical applications in different scenarios of bleeding and thrombotic disorders.

Abstract
Extreme thrombocytosis induces an acquired thrombotic-hemorrhagic diathesis, and left uncontrolled is a harbinger of potentially fatal vascular complications. Currently, cytoreduction with medical therapy remains the mainstay of hyperthrombocytosis management. However, it offers a less-than-ideal option in situations where a rapid reduction in platelets is urgently needed, as in the presence of vital end-organ ischemia or to ameliorate of life-threatening hemorrhage. The role of thrombocytapheresis, or plateletpheresis, in hyperthrombocytosis has become increasingly obsolete given the proactive titration of cytoreductive therapies and early identification and correction of reversible causes of reactive thrombocytosis. Despite its narrowed indications, plateletpheresis continues to offer a valuable temporizing measure in platelet count reduction before cytoreductive agents exert their maximal effect. In this context, it is important for the treating physician to be aware of the symptoms and risks associated with hyperthrombocytosis to inform best clinical practices. In this review, we discuss the role of plateletpheresis in the modern-day management of hyperthrombocytosis in patients with myeloproliferative neoplasms through a case based review of the literature. It becomes apparent throughout the discussion that the decision to perform plateletpheresis should be individualized based upon the clinical scenario, degree of thrombocytosis, available infrastructure and every patient's risk profile.

Abstract
BACKGROUND We explored the effects of repeated plateletpheresis on the platelet P-selectin expression and soluble P-selectin (sP-selectin) concentrations in platelet donors. METHODS Totally 289 platelet donors and 97 first-time whole blood (WB) donors were enrolled from the blood donor registry at the Fujian provincial blood center, China. The accumulative numbers of plateletpheresis in the last 2 y for participants were recorded, and the basal concentrations of platelet count, sP-selectin and total platelet P-selectin (pP-selectin) were determined. RESULTS Platelet donors had significantly higher basal concentrations of sP-selectin compared to WB donors (24.12±7.33ng/mL vs. 20.74±5.44ng/mL, P<0.0001), with no difference in platelet count and pP-selectin concentrations. Increased numbers of platelet donation were correlated with a steady increase of sP-selectin (r=0.18, P=0.002). Multivariate regression analysis identified that the frequency of plateletpheresis is an independent factor for the rise of the sP-selectin concentration (t=2.64, P=0.009) while no association was found for pP-selectin and platelet count. CONCLUSIONS Repeated plateletpheresis could result in an increased basal concentration of sP-selectin in blood donors whereas not an alteration in the concentrations of total platelet P-selectin. It remains to be determined whether this might be a consequence of endothelial activation or platelet activation or some other phenomenon.

Abstract
Rotation thrombelastogram (ROTEM®/TEG®) assays allow rapid global assessment of hemostatic function using whole blood. Since published data about the effects of automated red cell collection on coagulation system are scarce, we aimed to investigate the effects of 2-RBC apheresis on donor's coagulation system using ROTEM® assays. In INTEM assay, CFT was significantly shortened 24h after apheresis compared with baseline value (p<0.05) and MCF was significantly prolonged immediately after apheresis and 24h after apheresis compared with baseline value (p<0.05 and p<0.01, respectively). In EXTEM assay, CFT was significantly prolonged immediately after apheresis and 24h after apheresis compared with baseline value (p=0.001 and p<0.001, respectively) and MCF was significantly prolonged 24h after apheresis compared with baseline value (p<0,001). Our results demonstrate thromboelastographic signs of hypercoagulability in donors undergoing 2-RBC apheresis.
