Abstract
Patients with myelodysplastic syndrome (MDS) often need platelet transfusions to address thrombocytopenia. The risk of alloimmunization, particularly in Rhesus (Rh) incompatibility between donors and recipients during platelet transfusions, is heightened, especially with whole blood-derived pooled platelets as opposed to apheresis platelets. Although the occurrence of alloimmunization from platelet transfusions is minimal, there is an ongoing debate about whether Rh immune globulin (RhIg) should be administered to Rhesus D (RhD)-negative recipients of RhD-positive platelet units. We present a unique case of anti-D alloimmunization in a 56-year-old patient with underlying MDS following multiple platelet transfusions but never received packed cell transfusion or anti-D immunoglobulin. Some studies advocate for RhIg administration in specific scenarios and for certain patient populations. This case underscores the importance of considering Rhesus compatibility or administering anti-D immunoglobulin in cases where frequent platelet transfusions are required.

Abstract
Endoscopic procedures are essential in gastroenterology but pose significant risks for thrombocytopenic patients who have lower platelet counts, increasing the likelihood of bleeding complications. This systematic review and meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to assess bleeding risks in thrombocytopenic patients undergoing various endoscopic procedures. A comprehensive search was conducted across databases like PubMed, MEDLINE, and EBSCO, using stringent criteria for inclusion and exclusion, with study quality assessed via the Newcastle-Ottawa Scale and thrombocytopenia severity classified by Common Terminology Criteria for Adverse Events (CTCAE) criteria. Statistical analysis focused on bleeding event incidence rates at different platelet count thresholds, utilizing RevMan Web (Cochrane, London, UK) and Excel (Microsoft® Corp., Redmond, WA). The search yielded 1,675 potential articles, but only three retrospective cohort studies were selected. Results showed a significant increase in bleeding risk for patients with platelet counts below 50,000/mm3, particularly under 25,000/mm3, with a 5.5% prevalence of post-procedure bleeding in moderate to severe thrombocytopenic patients versus 4.0% in those with higher counts, and a threefold higher risk in severe thrombocytopenia. The study highlights the need for meticulous pre-procedure assessments in thrombocytopenic patients and points out disparities in guideline recommendations, suggesting personalized approaches based on patient-specific risks. It underscores balancing diagnostic yield against bleeding risks, especially in severe thrombocytopenia, and discusses the controversial role of prophylactic platelet transfusions, advocating for a nuanced approach. In conclusion, this meta-analysis provides critical insights into managing thrombocytopenia in endoscopic procedures, emphasizing the importance of individualized patient assessment and adherence to evolving guidelines, and underlining the necessity of further research to refine these guidelines and improve patient safety and outcomes in this challenging clinical scenario.

Abstract
ABSTRACT Myelodysplastic syndromes are a heterogeneous group of bone marrow disorders characterized by ineffective hematopoiesis, progressive cytopenias, and an innate capability of progressing to acute myeloid leukemia. The most common causes of morbidity and mortality are complications related to myelodysplastic syndromes rather than progression to acute myeloid leukemia. Although supportive care measures are applicable to all patients with myelodysplastic syndromes, they are especially essential in patients with lower-risk disease who have a better prognosis compared with their higher-risk counterparts and require longer-term monitoring of disease and treatment-related complications. In this review, we will address the most frequent complications and supportive care interventions used in patients with myelodysplastic syndromes, including transfusion support, management of iron overload, antimicrobial prophylaxis, important considerations in the era of COVID-19 (coronavirus infectious disease 2019), role of routine immunizations, and palliative care in the myelodysplastic syndrome population.

Abstract
INTRODUCTION Platelet products are scarce and expensive resources to be used judiciously. However, inappropriate usage is common. Lack of physician awareness is an important issue. We implemented a physician education program (PEP) along with repeated WhatsApp reminders at our centre. We audited the platelet usage practise before and after the intervention. METHODS Charts of patients with acute myeloid leukaemia (AML) treated between January 2020 and August 2020 was reviewed, and the mean platelet usage per patient per day was calculated. Physician education was implemented between September 2020 and December 2020 (2 PowerPoint lectures of 20 min each and weekly WhatsApp messages containing the guidelines). Data of patients treated between Jan 2021 and August 2021 was prospectively audited to understand platelet usage and the indications for transfusions. The British Committee for the Standards in Haematology (BCSH) platelet transfusion guidelines were used as the adjudication tool to evaluate compliance. The mean platelet usage per day per kg body weight of a patient before and after the PEP was compared using the t-test. RESULTS Group A (before physician education) consisted of 22 patients, and group B (after physician education) consisted of 23 patients. The mean number of platelet transfusions for each patient in a day per kg body weight was 125.7 × 108 in group A whereas, after the PEP, it had reduced to 73.9 × 108 amounting to an absolute reduction of 51 × 108 (58.8%) from the baseline with a statistical significance of P = 0.001. After implementing the PEP, the mean number of random donor platelets used reduced by 10.25 units (34% reduction), and the mean single donor platelets used reduced by 0.83 units (19% reduction). The 190 requests for platelet transfusion received during this period were classified as appropriate (157/190), which constituted 82.63% of the requests, or inappropriate (33/190), which accounted for 17.36%. CONCLUSIONS A short-duration education programme supplemented with weekly WhatsApp messages and an active feedback mechanism on the rationale of platelet transfusion by the treating physician and transfusion specialist could significantly reduce platelet consumption during the therapy of acute myeloid leukaemia patients. This is a measure that can be considered by all high-volume haematology centres, which can improve patient safety and reduce costs.

Abstract
Objective Transfusion of HLA-matched platelets can reduce the effect of alloimmune responses on platelet transfusion efficacy; however, finding HLA-matched platelets in the population is nearly impossible. Almost all HLA-matched platelets from related are half-matched, but the hemostatic efficacy of related donor platelets is unclear. Our goal was to compare the hemostatic effect of related donated platelets and unrelated donors platelets. Methods In this retrospective cohort study, we included acute leukemia and myelodysplastic syndrome patients with thrombocytopenia after chemotherapy. These patients were all transfused with platelets. This study excluded patients younger than 16 years and older than 65 years, or patients with abnormal coagulation parameters during platelet transfusion. We compared the hemostatic effect of related donated platelets and unrelated donors platelet. The primary outcome was transfusion efficacy after platelet transfusion, and the number of platelet counts and corrected count increments at 24 h after platelet transfusion. Result We analyzed 31 patients who received platelet transfusions from related donors (Treatment group) and 35 patients who received platelet transfusions from unrelated donors (Comparator group). Except for the relatively small proportion of patients with myelodysplastic syndrome in the treatment group, baseline clinical and laboratory characteristics were similar between the two groups. Hemostasis and prevention of bleeding in the treatment group showed significant superiority; the number of platelets increased 24 h after platelet transfusion in the treatment group was significantly higher than that in the comparator group. After 24 h, the corrected count increments treatment group was also higher than the comparator group; in the treatment group, the transfusion effect was better when the three sites of HLA-A, B, and C were identical, and the different blood types of platelet donors and recipients did not affect the transfusion effect. Conclusion Related donated platelets have better hemostasis and prevention effects, and no increase in adverse blood transfusion reactions. It may be a better transfusion strategy for platelet refractoriness patients in emergency situations.

Abstract
Background Reports suggest that the rate of adverse events (AEs) post-endoscopic sphincterotomy (ES) to be as high as 10%, with gastrointestinal bleeding being most common after post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Objective The aim of this study was to characterize the incidence of bleeding in patients with thrombocytopenia following ES. Design Retrospective observational cohort study. Methods Patients with thrombocytopenia (defined as <150,000 platelets/μL) who underwent ES between May 2017 and December 2020 were identified at a tertiary care medical center. The incidence of immediate (intraprocedural oozing >5 min or requiring intervention) or delayed (clinical bleeding with associated hemoglobin drop within 14 days) post-ES bleeding was determined via manual chart review. Results A total of 221 patients with a mean platelet count of 108,000 ± 13,000 platelets/μL underwent ERCP with ES. Immediate bleeding occurred in 11 (5%) patients with no significant drop in hemoglobin or transfusion requirement. Two patients (0.9%), both of whom were noted to have immediate bleeding, also developed delayed bleeding. Presence of malignancy was associated with an increased risk of bleeding (36.4% versus 11.4%, p = 0.037) while platelet count was not. Conclusion In a cohort of patients with thrombocytopenia, rates of immediate and delayed bleeding are similar to previously reported AE rates of ES in the general patient population. Careful attention should be given to patients with a history of active malignancy as well as those who develop immediate bleeding as they appear to be at increased risk for bleeding complications.

Abstract
Introduction Lusutrombopag is an oral thrombopoietin receptor agonist (TPO-RA). Clinical trials have shown lusutrombopag’s efficacy in reducing need for preoperative platelet transfusion in patients with chronic liver disease (CLD) and severe thrombocytopenia. This analysis assessed efficacy and safety of lusutrombopag in patients with severe thrombocytopenia and CLD undergoing planned invasive procedures. Methods An electronic database search (through 1 December 2020) identified three randomised, placebo-controlled, double-blind clinical trials comparing lusutrombopag with placebo in patients with CLD and platelet count below 50 × 109/L scheduled to undergo a procedure with a perioperative bleeding risk. A random-effects meta-analysis examined treatment effect, with Cochrane Collaboration’s tool assessing risk of bias. Results The meta-analysis included 343 (lusutrombopag 3 mg, n = 173; placebo, n = 170) patients. More patients met the criteria for treatment response (platelet count at least 50 × 109/L and increase of at least 20 × 109/L from baseline anytime during the study) with lusutrombopag versus placebo (risk ratio [RR] 6.39; 95% confidence interval [CI] 3.69, 11.07; p < 0.0001). The primary efficacy outcome, proportion of patients requiring no platelet transfusion and no rescue therapy for bleeding for at least 7 days post procedure, was achieved by more patients treated with lusutrombopag versus placebo (RR 3.42; 95% CI 1.86, 6.26; p = 0.0001). The risk of any bleeding event was significantly lower with lusutrombopag compared to placebo (RR 0.55; 95% CI 0.32, 0.95; p = 0.03); conversely, thrombosis event rates were similar between lusutrombopag and placebo (RR 0.79; 95% CI 0.19, 3.24; p = 0.74). Conclusion This meta-analysis showed that treatment of severe thrombocytopenia with lusutrombopag in patients with CLD prior to a planned invasive procedure was efficacious and safe in increasing platelet counts, avoiding the need for platelet transfusions, and reducing risk of bleeding, thereby enhancing the certainty of evidence supporting the efficacy and safety of lusutrombopag.

Abstract
Abstract
Background
Fiberoptic bronchoscopy (FOB) is a very important procedure in hematology clinics. Clinicians often worry about thrombocytopenia before performing FOB because hemorrhagic complications may occur during and after FOB. We have planned a retrospective study about hemorrhagic complications in thrombocytopenic patients who underwent FOB and treated for hematological malignancy. In this study, we have analyzed hemorrhagic complications, which are related to thrombocytopenia, in 114 adult patients who have hematologic malignancy and underwent FOB between January 1, 2005 and October 20, 2015. The platelet counts of all the patients were below 100 × 109/L.
Results
The complications related to FOB were observed in 4 (3.5%) out of 114 patient. Three out of 4 the complications were related to hemorrhage. One out of these 3 patients who occured hemorrhage was in “no bleeding group” according to BTS classification. The other 1 out of these 3 patients was in “mild bleeding” group. No bleeding was observed during FOB in the third patient. Hemoptysis was observed after FOB in the third patient, it was not required replacement and hemoptysis regressed spontaneously.
In this study, we categorized all the patients into three groups. The first group was comprised of 32 patients whose platelet counts were between 0 and 30 × 109/L. The second group was comprised of 47 patients whose platelets counts were between 30 and 50 × 109/L and lastly, the third group was comprised of 35 patients whose platelets counts were between 50 and 100 × 109/L. When we compared the groups to each other, there was no significant difference between these three groups in regards to occurrence of hemorrhagic complications. We observed that there was no significant relationship between thrombocytopenia level and risk of hemorrhagic complications in thrombocytopenic patients who underwent FOB.
Conclusions
In conclusion, this study demonstrated that FOB is safe procedures in thrombocytopenic patients if it is performed in multidisciplinary centers by experienced pulmonologists.

Abstract
OBJECTIVE Lusutrombopag is a thrombopoietin receptor agonist approved to treat thrombocytopenia in patients with chronic liver disease (CLD). This post hoc analysis of the Japanese L-PLUS 1 and global L-PLUS 2 trials aimed to clarify factors related to platelet count increase after lusutrombopag treatment. METHODS In L-PLUS 1, Pearson's correlation coefficients were used to evaluate correlations between platelet count and spleen index, thrombopoietin concentration, white blood cell (WBC) counts, and red blood cell counts (intent-to-treat [ITT] population). Associations between platelet count increase after lusutrombopag treatment and each parameter were assessed by regression analysis and mixed-effect model for repeated measures (MMRM). Associations between time-dependent changes in platelet count increase and each parameter were also examined in the L-PLUS 2 lusutrombopag ITT population by MMRM. RESULTS In L-PLUS 1, the baseline platelet count was correlated with pretreatment spleen index (r = -0.23, 95% confidence interval [CI] -0.41 to -0.03) and WBC count (r = 0.26, 95% CI 0.06 to 0.43). No selected parameters were associated with the maximum platelet count increase from baseline. Patients with WBC counts below the normal range showed smaller platelet count increases after lusutrombopag treatment than patients with WBC counts within the normal range (p = .0028). In L-PLUS 2 (p = .0533), findings were similar and confirmed by larger pooled data of L-PLUS 1/L-PLUS 2 (p = .0021). CONCLUSIONS This post hoc analysis revealed a possible association between baseline WBC count and platelet count increase after lusutrombopag treatment. WBC count could be a relevant factor for lusutrombopag efficacy.

Abstract
Background Gastrointestinal cancer demands a high frequency of transfusions, and the high availability of blood products. We aimed to determine the frequency of blood transfusions and the most used blood products according to the type of gastrointestinal cancer. Methods A cross-sectional study was conducted in a Peruvian Type I Hemotherapy and Blood Bank Service of a Private Oncological Clinic during 2016–2018. We included patients with gastrointestinal cancer using the International Code of Diseases. The donations were made in compliance with the requirements of the Programa Nacional de Hemoterapía y Banco de Sangre and in accordance with the Standardised Operational Procedure of the clinic. Results We analysed 3,022 patients, of which 163 (5.4%) had gastrointestinal cancer (67.1 ± 12 years). The 80 (49.1%) men did not show significant differences with the 83 (50.9%) women (p = 0.178). The most frequent neoplasia was the colon (41.7%) and pancreas (37.4%). Three hundred and four blood products were transfused (average 1.8 ± 2.5 units (range: 1–30 units/patient)), of which 81.3% (247 units) were red blood cells concentrated, 8.6% (26 units) were fresh-frozen-plasma (FFP) and 6.6% (20 units) were cryoprecipitate. The type of cancer that most blood products demanded was colon neoplasia (41.8%), followed by pancreatic cancer (26.3%) and liver cancer (10.9%). We determined that ~55% of patients were O Rh(D)+ and in five patients we were poly-transfused. Conclusion Our findings suggested that patients with gastrointestinal cancer require large numbers of transfusions of blood cell concentrate and FFP. Also, we showed that cancer of the colon, pancreas and liver demanded more than 75% of blood products.

Abstract
PURPOSE OF REVIEW In this review, we discuss current clinical guidelines and potential underlying mechanisms regarding platelet transfusion therapy in patients at risk of bleeding, comparing management of patients with thrombocytopenia versus those with qualitative platelet disorders. RECENT FINDINGS Platelet transfusion therapy is highly effective in managing bleeding in patients with hypoproliferative thrombocytopenia. Clinical trials have demonstrated that platelet transfusion can be used at a lower trigger threshold and reduced platelet doses, and may be used therapeutically rather than prophylactically in some situations, although additional data are needed. In patients with inherited platelet disorders such as Glanzmann's Thrombasthenia or those with RASGRP2 mutations, platelet transfusion may be ineffective because of competition between transfused and endogenous platelets at the site of vascular injury. Successful management of these patients may require transfusion of additional platelet units, or mechanism-driven combination therapy with other pro-hemostatic agents. In patients on antiplatelet therapy, timing of transfusion and inhibitor mechanism-of-action are key in determining therapeutic success. SUMMARY Expanding our understanding of the mechanisms by which transfused platelets exert their pro-hemostatic function in various bleeding disorders will improve the appropriate use of platelet transfusion.

An epitope-based approach of HLA-matched platelets for transfusion: a noninferiority crossover randomized trial. Blood 2021; 137:310-322. [PMID: 33475737 DOI: 10.1182/blood.2020007199] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 09/21/2020] [Indexed: 11/20/2022] Open
Abstract
Platelet transfusion refractoriness results in adverse outcomes and increased health care costs. Managing refractoriness resulting from HLA alloimmunization necessitates the use of HLA antigen-matched platelets but requires a large platelet donor pool and does not guarantee full matching. We report the first randomized, double-blind, noninferiority, crossover trial comparing HLA epitope-matched (HEM) platelets with HLA standard antigen-matched (HSM) platelet transfusions. Alloimmunized, platelet-refractory, thrombocytopenic patients with aplastic anemia, myelodysplastic syndrome, or acute myeloid leukemia were eligible. HEM platelets were selected using HLAMatchMaker epitope (specifically eplet) matching. Patients received up to 8 prophylactic HEM and HSM transfusions provided in random order. The primary outcome was 1-hour posttransfusion platelet count increment (PCI). Forty-nine patients were randomized at 14 UK hospitals. For intention to treat, numbers of evaluable transfusions were 107 and 112 for HEM and HSM methods, respectively. Unadjusted mean PCIs for HEM and HSM methods were 23.9 (standard deviation [SD], 15) and 23.5 (SD, 14.1), respectively (adjusted mean difference, -0.1; 95% confidence interval [CI], -2.9 to 2.8). Because the lower limit of the 95% CI was not greater than the predefined noninferiority limit, the HEM approach was declared noninferior to the HSM approach. There were no differences in secondary outcomes of platelet counts, transfusion requirements, and bleeding events. Adequate 1-hour PCI was more frequently observed, with a mean number of 3.2 epitope mismatches, compared with 5.5 epitope mismatches for inadequate 1-hour increments. For every additional epitope mismatch, the likelihood of an adequate PCI decreased by 15%. Epitope-matched platelets should be considered to support HLA alloimmunized patients. This trial was registered at www.isrctn.com as #ISRCTN23996532.

Abstract
PURPOSE To assess the safety of fluoroscopically guided drill-assisted bone marrow aspirate and biopsy in severely thrombocytopenic patients. MATERIALS AND METHODS The study was approved by the IRB with waiver of informed consent. Retrospective review of 111 bone marrow aspirate and biopsies (BMAB) performed in 94 patients who received a CT scan which included the pelvis and biopsy site within the 7 days following the BMAB. The 94 patients were subdivided based on their platelet count: severe thrombocytopenia (< 20 platelets × 109/L), thrombocytopenia (20-50 platelets × 109/L), and control (> 50 platelets × 109/L). The procedure report was reviewed for sedation time, aspirate volume, and aggregate size of core biopsy specimens. The electronic medical record was reviewed for specimen adequacy; pathologic diagnosis; body mass index; pre- and post-procedure labs including platelet count, hemoglobin (HGB), hematocrit (HCT), prothrombin time (PT), and international normalized ratio (INR) levels; post-procedural transfusion; and complications including mortality at 30 and 90 days. CT scans were independently reviewed by 2 fellowship-trained radiologists for the presence of post-procedural hemorrhage. RESULTS There was no significant difference in CT-identified post-procedural hematoma, or change in the hemoglobin and hematocrit levels pre- and post-procedure between the three groups. There was no significant difference in complication rate or all-cause mortality. There was a significant difference in transfusion at 30 days with thrombocytopenic and severely thrombocytopenic patients more likely to receive transfusion within the 30 days post-procedure. CONCLUSION Fluoroscopically guided BMAB can be safely performed in patients with severe thrombocytopenia.

Abstract
Background Novel coronavirus disease 2019 (COVID-19) is known to lead not only to severe acute respiratory syndrome, but also can result in thromboembolic events in both the venous and the arterial circulation by inducing coagulation disorders. The potential causes of coagulopathy are inflammation, platelet activation, endothelial dysfunction, and stasis. The thrombotic events including pulmonary embolism, deep venous thrombosis as well as intracatheter thrombosis are more likely to develop in patients infected with severe form of SARS-CoV-2 who are admitted to ICU. Furthermore, these events contribute to multi-organ failure. Case presentation Herein, we report a case of an immunocompromised COVID-19 elderly patient with acute lymphocytic leukemia who developed myocardial infarction with ST elevation in the setting of acute pulmonary thromboembolism in the presence of zero platelet count. Despite successful urgent coronary revascularization and platelet transfusion, the patient eventually died after failed resuscitation efforts. Conclusion Patients with COVID-19 infection are at a greater risk of developing cardiovascular complications, but their appropriate management can decrease the risk of fatal events. Coronary thrombosis associated with pulmonary thromboembolism in the setting of thrombocytopenia is a rare and a complex to manage condition. Significance of single antiplatelet agent in STEMI with thrombocytopenia merits further studies. According to expert opinions and literature reviews, we must avoid dual antiplatelet therapy in these patients and keep platelet transfusion as a standard therapy to avoid drastic bleeding complications.

Abstract
BACKGROUND Clinical laboratories have traditionally used a single critical value for thrombocytopenic events. This system, however, could lead to inaccuracies and inefficiencies, causing alarm fatigue and compromised patient safety. OBJECTIVES This study shows how machine learning (ML) models can provide auxiliary information for more accurate identification of critical thrombocytopenic patients when compared with the traditional notification system. RESEARCH DESIGN A total of 50,505 patients' platelet count and other 26 additional laboratory datasets of each thrombocytopenic event were used to build prediction models. Conventional logistic regression and ML methods, including random forest (RF), artificial neural network, stochastic gradient descent (SGD), naive Bayes, support vector machine, and decision tree, were applied to build different models and evaluated. RESULTS Models using logistic regression [area under the curve (AUC)=0.842], RF (AUC=0.859), artificial neural network (AUC=0.867), or SGD (AUC=0.826) achieved the desired average AUC>0.80. The highest positive predictive value was obtained by the SGD model in the testing data (72.2%), whereas overall, the RF model showed higher sensitivity and total positive predictions in both the training and testing data and outperformed other models. The positive 2-day mortality predictive rate of RF methods is as high as 46.1%-significantly higher than using the traditional notification system at only 14.8% [χ2(1)=81.66, P<0.001]. CONCLUSIONS This study demonstrates a data-driven ML approach showing a significantly more accurate 2-day mortality prediction after a critical thrombocytopenic event, which can reinforce the accuracy of the traditional notification system.

Abstract
BACKGROUND In the ENGAGE AF-TIMI 48 (Effective Anticoagulation with Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis In Myocardial Infarction 48) trial, the lower dose edoxaban regimen (LDER) and the higher dose edoxaban regimen (HDER) were noninferior to well-managed warfarin for stroke prevention in atrial fibrillation. OBJECTIVES The objective of the present analysis of the ENGAGE AF TIMI-48 trial was to comprehensively compare the net clinical outcome (NCO) of LDER (30 mg once daily, dose reduced to 15 mg in selective patients) versus HDER (60 mg once daily, dose reduced to 30 mg in selective patients). METHODS This study performed a pre-specified analysis of the ENGAGE AF-TIMI 48 trial, comparing patients on LDER versus HDER. RESULTS The pre-defined primary NCO (stroke/systemic embolism [SEE], major bleeding, death) was less frequent with LDER (7.26% vs. 8.01%; hazard ratio: 0.90; 95% confidence interval: 0.84 to 0.98; p = 0.014). The secondary (disabling stroke, life-threatening bleeding, or all-cause mortality) and tertiary pre-defined NCOs (stroke, SEE, life-threatening bleeding, or all-cause mortality) were similar between the 2 dosing regimens. Patients randomized to LDER versus HDER had a significantly higher risk of stroke/SEE (2.04% vs. 1.56%; hazard ratio: 1.31; 95% confidence interval: 1.12 to 1.52; p < 0.001). Conversely, major bleeding, intracranial hemorrhage, major gastrointestinal bleeding, and life-threatening bleeding occurred significantly less frequently with LDER compared with those of HDER. These findings were supported by multiple pharmacokinetic findings. CONCLUSIONS In the ENGAGE AF-TIMI 48 trial, the primary NCO was reduced with LDER versus HDER, whereas the secondary and tertiary NCOs were similar between the 2 dosing regimens. These results may aid physicians in evidence-based individualization of edoxaban dosing. However, the approved HDER remains the standard therapy among the available edoxaban dosing regimens for stroke prevention in atrial fibrillation.

Abstract
BACKGROUND Platelet transfusion refractoriness (PTR) secondary to human leukocyte antigen (HLA) alloimmunization is a challenge in the treatment of hematology-oncologypatients and increases the risk of morbidity and mortality from bleeding events. Guidelines for treating PTR have not been clearly described in literature. We aim to describe the practice patterns for the management of PTR secondary to HLA alloimmunization, and to assess the mortality, thrombosis and bleeding-related clinical outcomes at 30 days from diagnosis. METHODS A retrospective review of 51 cases of PTR secondary to HLA alloimmunization were analyzed. RESULTS The majority of patients (98 %) had a diagnosis of hematological malignancy of which 88.2 % were undergoing active chemotherapy. Clinically relevant bleeding, by ISTH criteria, was observed in 33.3 %; hemorrhagic shock was diagnosed in 7%. The rate of bleeding-related mortality was estimated at 7.8 %. The use of antifibrinolytics and plasma products (including intravenous immunoglobulin) was more common in cases with major versus non-major bleeding. Grade A or B1U HLA matched products were available in less than half of cases. CONCLUSIONS There is heterogeneity in the management of the bleeding risk and bleeding events during PTR, with antifibrinolytics more commonly used in patients who suffered severe bleeding. Grade A and B1U HLA-matched platelets are not always readily available, and HLA-typing and HLA-antibody testing are not always performed prior to PTR. Prospective randomized control trials may help to determine the safety and efficacy of antifibrinolytics and other supportive measures in the management of PTR.

Abstract
Chemoradiotherapy and autoimmune disorder often lead to secondary thrombocytopenia in cancer patients, and thus, platelet transfusion is needed to stop or prevent bleeding. However, the effect of platelet transfusion remains controversial for the lack of agreement on transfusion strategies. Before being transfused, platelets are stored in blood banks, and their activation is usually stimulated. Increasing evidence shows activated platelets may promote metastasis and the proliferation of cancer cells, while cancer cells also induce platelet activation. Such a vicious cycle of interaction between activated platelets and cancer cells is harmful for the prognosis of cancer patients, which results in an increased tumor recurrence rate and decreased five-year survival rate. Therefore, it is important to explore platelet transfusion strategies, summarize mechanisms of interaction between platelets and tumor cells, and carefully evaluate the pros and cons of platelet transfusion for better treatment and prognosis for patients with cancer with secondary thrombocytopenia.

Abstract
Abstract
Background
Bone marrow transplantation (BMT) is a therapeutic procedure for the management of several hematological diseases and malignancies in pediatric population. Central venous catheters (CVCs) play a pivotal role during the process of BMT. The aim of this study was to compare the complications of CVCs placements in children undergoing BMT with platelet levels above and below 50,000/μL and also to detect if there is a platelet count for a safe insertion. This prospective study included all children who had placements of tunneled CVCs during BMT at our hospital between March 2017 and March 2020. Procedures were divided into two groups accordingly to preoperative platelet counts (above and below 50,000/μL). Data were compared between both groups regarding postoperative complications including bleeding or catheter-related blood stream infections (CRBSIs).
Results
Forty-six CVC insertions were performed in 40 patients. There were 20 procedures below 50,000/μL (median 27,500; range 5000–42,000) inserted with perioperative platelet transfusions, and their postoperative levels were median 59,500/μL, range 18,000–88,000. Allogeneic BMT was adopted in 39 patients (97.5%). Beta thalassemia major was the commonest indication (21/40, 52.5%), followed by acute lymphocytic leukemia in six patients (15%). There were nine postoperative complications (bleeding n = 2 and CRBSIs n = 7) encountered in all placements. Four of them occurred in insertions below 50,000/μL (two bleeding complications that managed conservatively, and two CRBSIs). Post-procedural morbidities regarding bleeding or CRBSIs did not differ significantly between both groups (p value = 0.099 and 0.695, respectively).
Conclusions
Postponement of CVC insertions in thrombocytopenic children due to the fear of potential complications seems unwarranted, as it has no significant impact on the morbidity. Placements of such catheters can be safe under cover of perioperative platelet transfusions irrespective of the preoperative platelet count.

Abstract
Patients with cancer are at increased risk of cardiovascular disease, with a reported prevalence of acute coronary syndrome (ACS) ranging from 3% to 17%. The increased risk of ACS in these patients seems to be due to the complex interaction of shared cardiovascular risk factors, cancer type and stage, and chemotherapeutic and radiotherapy regimens. The management of ACS in patients with cancer is a clinical challenge, particularly due to cancer’s unique pathophysiology, which makes it difficult to balance thrombotic and bleeding risks in this specific patient population. In addition, patients with cancer have largely been excluded from ACS trials. Hence, an evidence-based treatment for ACS in this group of patients is unknown and only a limited proportion of them is treated with antiplatelets or invasive revascularization, despite initial reports suggesting their beneficial prognostic effects in cancer patients. Finally, cancer patients experiencing ACS are also at higher risk of in-hospital and long-term mortality as compared to non-cancer patients. In this review, we will provide an overview on the available evidence of the relationship between ACS and cancer, in terms of clinical manifestations, possible underlying mechanisms, and therapeutic and prognostic implications.

Abstract
BACKGROUND In the intensive care unit (ICU), patients with thrombocytopenia are at high risk for bleeding and should be assessed for their thrombogenic potential. However, the analytical conditions of conventional hemostatic tests are unsuitable for the evaluation of low-platelet samples. Here we aimed to establish suitable analytical conditions with the Total Thrombus-formation Analysis System (T-TAS) for quantitative assessment of thrombogenic potential in patients with thrombocytopenia and to investigate how T-TAS values relate to bleeding symptoms and the effects of platelet transfusion. METHODS Modified chips with a different chamber depth were developed for the analysis of low-platelet samples in the T-TAS. We included 10 adult patients admitted to the ICU of Kagoshima University Hospital who required platelet transfusion. Patients were divided into major and minor bleeding groups according to their bleeding scale before platelet transfusion. The thrombogenic potential of these patients before and after platelet transfusion was assessed with hemostatic function tests, including rotational thromboelastometry, multiplate aggregometry, and the T-TAS. RESULTS Analysis of low-platelet samples revealed that, compared with the conventional chip (80-μm-deep chamber), the modified chip (50-μm-deep chamber) achieved higher sensitivity in detecting elevation of flow pressure caused by growth of an occlusive thrombus in the T-TAS analytical chamber. All patients in the minor bleeding group retained thrombogenic potential that occluded the modified chip (occlusion time 16.3 ± 3.3 min), whereas most patients in the major bleeding group were unable to occlude the modified chip during the 30-min measurement (P < 0.01). The recovery of thrombogenic potential after platelet transfusion was confirmed with the T-TAS and correlated with the function, rather than the count, of transfused platelets. Among all evaluated parameters in hemostatic function tests, only the T-TAS showed significant differences in occlusion time and area under the curve both between the minor and major bleeding groups and between pre- and post-platelet transfusion. CONCLUSIONS We developed a modified microchip-based flow chamber system that reflects the hemostatic function of patients with thrombocytopenia.

Comparison of the platelet activation status of single-donor platelets obtained with two different cell separator technologies. Transfusion 2020; 60:2067-2078. [PMID: 32729161 DOI: 10.1111/trf.15934] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Revised: 05/06/2020] [Accepted: 05/24/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND The microparticle content (MP%) of apheresis platelets-a marker of platelet activation-is influenced by donor factors and by external stressors during collection and storage. This study assessed the impact of apheresis technology and other factors on the activation status (MP%) of single-donor apheresis platelets. STUDY DESIGN AND METHODS Data from six US hospitals that screened platelets by measuring MP% through dynamic light scattering (ThromboLUX) were retrospectively analyzed. Relative risks (RRs) were derived from univariate and multivariable regression models, with activation rate (MP% ≥15% for plasma-stored platelets; ≥10% for platelet additive solution [PAS]-stored platelets) and MP% as outcomes. Apheresis platform (Trima Accel vs Amicus), storage medium (plasma vs PAS), pathogen reduction, storage time, and testing location were used as predictors. RESULTS Data were obtained from 7511 platelet units collected using Trima (from 16 suppliers, all stored in plasma, 20.0% were pathogen-reduced) and 2456 collected using Amicus (from four different collection facilities of one supplier, 65.0% plasma-stored, 35.0% PAS-stored, none pathogen-reduced). Overall, 30.0% of Trima platelets were activated compared to 45.6% of Amicus platelets (P < .0001). Multivariable analysis identified apheresis platform as significantly associated with platelet activation, with a lower activation rate for Trima than Amicus (RR: 0.641, 95% confidence interval [CI]: 0.578; 0.711, P < .0001) and a 6.901% (95% CI: 5.926; 7.876, P < .0001) absolute reduction in MP%, when adjusting for the other variables. CONCLUSION Trima-collected platelets were significantly less likely to be activated than Amicus-collected platelets, irrespective of the storage medium, the use of pathogen reduction, storage time, and testing site.

Abstract
Platelet-rich-plasma (PRP) is an autologous human platelet concentrate extracted from plasma. PRP has been investigated in order to be used in many fields, with emphasis on the musculoskeletal field applied to sports injuries, as well as on other medical fields such as cardiac surgery, gynecology, pediatric surgery, urology, ophthalmology and plastic surgery. Cancer treatment is another important field where PRP should be investigated; thus, it is important validating PRP preparation protocols to be used in clinical research. Many protocols should be revised since, overall, most studies do not provide necessary information to allow them to be multiplied or replicated. The current review focuses on several topics about cancer, mainly on innovative studies about PRP use as a feasible therapeutic alternative to treat bladder cancer - a field where it could play a key role. Relevant aspects such as platelets' contribution to immune regulation and the supportive role they play in innate and adaptive immune functions are also addressed. Another important topic reviewed in the current study refers to inflammatory process regulation associated with cancer and thrombosis sites, which indicated that tumor-induced platelet activation could be used as an important therapeutic target in the future. New aspects concerning nitric oxide's ability to restrain platelet adhesion and aggregation in order to slow metastasis progress in cancer patients provide an important advantage in cancer treatment. Finally, the current review has pointed out perspectives and the main concerns about, and possibilities of, PRP use in cancer treatment.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Current meta-analysis was conducted aiming to assess the efficacy and safety of recombinant human interleukin-11 (rhIL-11) in the treatment of acute leukaemia (AL) patients with chemotherapy-induced thrombocytopenia (CIT). METHODS We searched PubMed, Embase, Chinese National Knowledge Infrastructure database (CNKI), Cochrane Library, and Wan Fang Database on 4 July 2018. RESULTS Ten randomized controlled trials (RCTs) and two observational studies were included, which involved 754 AL patients with CIT. Pooled analysis demonstrated that rhIL-11 was beneficial on CIT: recovery time of platelet count to 50 × 109 /L [weight mean difference (WMD) = -4.19 days; 95% CI: -5.01, -3.37], recovery time of platelet count to 100 × 109 /L (WMD = -4.45 days; 95% CI: -4.85, -4.06), platelet transfusion volume (WMD = -6.14 U; 95% CI: -9.20, -3.09), and the rate of haemorrhage (RR = 0.46; 95% CI: 0.36 to 0.61). Most adverse events associated with rhIL-11 were mild to moderate. CONCLUSION Our findings suggest that rhIL-11 is effective and safe in the treatment of CIT in patients with AL.

Abstract
A 45-year-old man with idiopathic aplastic anemia required renal replacement therapy (RRT) due to end-stage renal disease (ESRD). We succeeded in inserting the peritoneal dialysis (PD) catheter under cover of frequent red blood cell and platelet infusions because of severe pancytopenia. During the one-year period after starting PD using an ultraviolet-ray sterilization device, he developed severe leukopenia but no PD-related peritonitis or exit site/tunnel infection until he died of pneumonia. This case suggests that PD might be a suitable choice as RRT in ESRD patients with aplastic anemia, even in those with severe pancytopenia.

Abstract
Pediatric oncology patients will likely require numerous transfusions of blood products, including red blood cell, platelet, and plasma transfusions, during the course of their treatment. Although strong evidence-based guidelines for these products in this patient population do not exist, given the morbidities associated with the receipt of blood products, practitioners should attempt to use restrictive transfusion strategies.

Abstract
OBJECTIVES To describe the epidemiology of platelet transfusions in critically ill children with an underlying oncologic diagnosis and to examine effects of prophylactic versus therapeutic transfusions. DESIGN Subgroup analysis of a prospective, observational study. SETTING Eighty-two PICUs in 16 countries. PATIENTS All children (3 d to 16 yr old) who received a platelet transfusion during one of the six predefined screening weeks and had received chemotherapy in the previous 6 months or had undergone hematopoietic stem cell transplantation in the last year. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of the 548 patients enrolled in the parent study, 237 (43%) had an underlying oncologic diagnosis. In this population, 71% (168/237) of transfusions were given prophylactically, and 59% (139/237) of transfusions were given at a total platelet count greater than 20 × 10/L, higher than the current recommendations. Those with an underlying oncologic diagnosis were significantly older, and received less support including less mechanical ventilation, fewer medications that affect platelet function, and less use of extracorporeal life support than those without an underlying oncologic diagnosis. In this subpopulation, there were no statistically significant differences in median (interquartile range) platelet transfusion thresholds when comparing bleeding or nonbleeding patients (50 × 10/L [10-50 × 10/L] and 30 × 10/L [10-50 × 10/L], respectively [p = 0.166]). The median (interquartile range) interval transfusion increment in children with an underlying oncologic diagnosis was 17 × 10/L (6-52 × 10/L). The presence of an underlying oncologic diagnosis was associated with a poor platelet increment response to platelet transfusion in this cohort (adjusted odds ratio, 0.46; 95% CI, 0.22-0.95; p = 0.035). CONCLUSIONS Children with an underlying oncologic diagnosis receive nearly half of platelet transfusions prescribed by pediatric intensivists. Over half of these transfusions are prescribed at total platelet count greater than current recommendations. Studies must be done to clarify appropriate indications for platelet transfusions in this vulnerable population.

How low can you go: What is the safe threshold for platelet transfusions in patients with hematologic malignancy in sub-Saharan Africa. PLoS One 2019; 14:e0211648.

Abstract
Background Despite the importance of platelet transfusions in treatment of hematologic cancer patients, the optimal platelet count threshold for prophylactic transfusion is unknown in sub-Saharan Africa. Methods We followed patients admitted to the Uganda Cancer Institute with a hematological malignancy in 3 sequential 4-month time-periods using incrementally lower thresholds for prophylactic platelet transfusion: platelet counts ≤ 30 x 109/L in period 1, ≤ 20 x 109/L in period 2, and ≤ 10 x 109/L in period 3. Clinically significant bleeding was defined as WHO grade ≥ 2 bleeding. We used generalized estimating equations (GEE) to compare the frequency of clinically significant bleeding and platelet transfusions by study period, adjusting for age, sex, cancer type, chemotherapy, baseline platelet count, and baseline hemoglobin. Results Overall, 188 patients were enrolled. The median age was 22 years (range 1–80). Platelet transfusions were given to 42% of patients in period 1, 55% in period 2, and 45% in period 3. These transfusions occurred on 8% of days in period 1, 12% in period 2, and 8% in period 3. In adjusted models, period 3 had significantly fewer transfusions than period 1 (RR = 0.6, 95% CI 0.4–0.9; p = 0.01) and period 2 (RR = 0.5, 95% CI 0.4–0.7; p<0.001). Eighteen patients (30%) had clinically significant bleeding on at least one day in period 1, 23 (30%) in period 2, and 15 (23%) in period 3. Clinically significant bleeding occurred on 8% of patient-days in period 1, 9% in period 2, and 5% in period 3 (adjusted p = 0.41). Thirteen (21%) patients died in period 1, 15 (22%) in period 2, and 11 (19%) in period 3 (adjusted p = 0.96). Conclusion Lowering the threshold for platelet transfusion led to fewer transfusions and did not change the incidence of clinically significant bleeding or mortality, suggesting that a threshold of 10 x 109/L platelets, used in resource-rich countries, may be implemented as a safe level for transfusions in sub-Saharan Africa.

Abstract
BACKGROUND Recent reports have indicated that the risk of anti-D alloimmunization following D-incompatible platelet (PLT) transfusion is low in hematology and oncology patients. We investigated the rate of anti-D alloimmunization in RhD-negative (D- ) patients with chronic liver disease transfused with D+ platelet concentrates (PCs) and the factors involved, at a liver transplant (LT) center. STUDY DESIGN AND METHODS We reviewed the blood bank database from January 2003 to October 2016. D- patients who had received D+ PLT transfusions were eligible if they had undergone antibody screening at least 28 days after the first D+ PC transfusion, had no previous or concomitant exposure to D+ blood products, and had not received anti-D immunoglobulins. RESULTS Six of the 56 eligible patients (10.7%) had anti-D antibodies. All had received whole blood-derived PCs. Four of 20 patients (20%) untransplanted or transfused before LT and only two of 36 patients (5.6%) transfused during or after LT produced anti-D antibodies. These two patients were on maintenance immunosuppression based on low-dose steroids and tacrolimus. The factors identified as significantly associated with anti-D immune response were the presence of red blood cell immune alloantibodies before D+ PLT transfusion (p = 0.003), and D+ PLT transfusion outside the operative and postoperative (5 days) periods for LT (p = 0.023). CONCLUSION D- patients with chronic liver disease transfused with D+ PLTs before LT are at high risk of developing anti-D antibodies. Preventive measures should be considered for these patients.

Abstract
Chemotherapy-induced thrombocytopenia (CIT) is a frequent complication of cancer therapy, leading to increased risk of bleeding, when the thrombocytopenia is severe (<10,000/mcL). However, the major clinical relevance of CIT is the subsequent delay or dose reduction in chemotherapy. CIT, therefore, leads to reduced relative dose intensity (RDI) of cancer therapy. Reduced RDI has been shown in several studies to impact progression-free survival and other cancer outcomes. While there are a number of factors leading to reduced RDI, CIT is a common cause. We review the causes and clinical manifestations of CIT, the current recommendations for management, and the status of research to develop targeted therapies to treat CIT.

[PMID: 30222860 DOI: 10.1111/trf.14886] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 05/01/2018] [Accepted: 06/06/2018] [Indexed: 12/01/2022]
Abstract
BACKGROUND Decisions on prophylactic platelet (PLT) transfusions are generally based on the recipient's PLT count, but few clinicians are aware of precision and accuracy of the PLT counting methods used by the clinical laboratory. Each PLT counting technology has its specific inaccuracy, especially in thrombocytopenic samples and therefore may impact decisions on PLT transfusions. STUDY DESIGN AND METHODS Five routine PLT counting methods available in two hematology analyzers (Sysmex XN-2000 and Abbott CELL-DYN Sapphire) were investigated (impedance and optical on both analyzers and fluorescent on XN-2000), using the CD61 immunologic PLT method as a reference. The impact of counting inaccuracy on imaginary transfusion decisions was examined at various common PLT thresholds. RESULTS In total 341 samples were analyzed, 178 of which had PLT counts of less than 35 × 109 /L. Despite excellent overall correlation with the reference method (r > 0.99), thrombocytopenic samples showed only modest correlation for impedance and XN-2000 optical methods. Sapphire optical and XN-2000 fluorescent methods correlated very well with the reference, albeit with bias in the very low range. We noticed potential risk of undertransfusion (ranging from 2% to 90%), depending on the threshold used. The risk of overtransfusion was small (<10%). CONCLUSIONS The XN-2000 fluorescent PLT counting method showed excellent correlation with the CD61 reference count, closely followed by the CELL-DYN Sapphire optical method. XN-2000 impedance and optical and Sapphire impedance methods are not accurate enough for basing transfusion decisions on. Only XN-2000 fluorescent, Sapphire optical, and CD61 methods are sufficiently accurate for making appropriate clinical decisions in patients with severe thrombocytopenia.

Abstract
BACKGROUND Fibrinogen concentrate can improve clot firmness and offers a better safety profile than platelet concentrates. Reduction or avoidance of blood transfusions represents a strategy to reduce associated risks. We investigated whether supplementation of fibrinogen concentrate ex vivo can compensate for clot strength as compared with platelet transfusion in vivo METHODS: One hundred patients in need of platelet transfusion (PT) were enrolled. Blood samples were collected immediately before PT and at 1 h and 24 h after PT. Fibrinogen concentrate was added to these citrated whole blood samples at concentrations of 50, 100, 200 and 400 mg kg-1 and the maximum clot firmness (MCF) was analysed using ROTEM thromboelastometry. RESULTS Fibrinogen supplementation increased MCF significantly and dose-dependently before and after PT. The effect of fibrinogen concentrate (equivalent to doses of 100 and 200 mg kg-1) ex vivo was comparable to that of PT in vivo, whereas 400 mg kg-1 fibrinogen significantly improved MCF compared with PT (P < 0.001). CONCLUSIONS Fibrinogen concentrate can match the effect of PT on MCF in thrombocytopenia. This potential alternative haemostatic intervention should be evaluated in clinical trials.

Abstract
Drug-induced hematological cytopenia is common in kidney transplantation. Various cytopenia including leucopenia (neutropenia), thrombocytopenia, and anemia can occur in kidney transplant recipients. Persistent severe leucopenia or neutropenia can lead to opportunistic infections of various etiologies. On the contrary, reducing or stopping immunosuppressive medications in these events can provoke a rejection. Transplant clinicians are often faced with the delicate dilemma of balancing cytopenia and rejection from adjustments of immunosuppressive regimen. Differentials of drug-induced cytopenia are wide. Identification of culprit medication and subsequent modification is also challenging. In this review, we will discuss individual drug implicated in causing cytopenia and correlate it with corresponding literature evidence.

Abstract
Multiple myeloma is a plasma cell neoplasm that has seen impressive improvements in outcomes in recent years with combination therapies, such as proteasome inhibitors and immunomodulatory drugs. Histone deacetylase inhibition is an additional unique mechanism of action with established biological relevance in multiple myeloma. Panobinostat is the first histone deacetylase inhibitor indicated for the treatment of relapsed/refractory multiple myeloma in patients who have received at least two prior regimens, including bortezomib and an immunomodulatory agent. While the addition of panobinostat to bortezomib and dexamethasone has demonstrated response and progression-free survival benefits, the incidence and severity of adverse events associated with it can create a challenge for clinicians and patients. Specifically, diarrhea, myelosuppression, an increased risk for infectious complications, cardiotoxicity, and nausea/vomiting may be seen with use. The frequency and grade of adverse event occurrence may differ between doses and schedule of panobinostat as well as with different companion therapies and routes. Herein we discuss the incidence, severity, and practical management of adverse events associated with panobinostat in the treatment of relapsed/refractory multiple myeloma.

Abstract
BACKGROUND Bone marrow disorders encompass a group of diseases characterised by reduced production of red cells, white cells, and platelets, or defects in their function, or both. The most common bone marrow disorder is myelodysplastic syndrome. Thrombocytopenia, a low platelet count, commonly occurs in people with bone marrow failure. Platetet transfusions are routinely used in people with thrombocytopenia secondary to bone marrow failure disorders to treat or prevent bleeding. Myelodysplastic syndrome is currently the most common reason for receiving a platelet transfusion in some Western countries. OBJECTIVES To determine whether a therapeutic-only platelet transfusion policy (transfusion given when patient is bleeding) is as effective and safe as a prophylactic platelet transfusion policy (transfusion given to prevent bleeding according to a prespecified platelet threshold) in people with congenital or acquired bone marrow failure disorders. SEARCH METHODS We searched for randomised controlled trials (RCTs), non-RCTs, and controlled before-after studies (CBAs) in the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2017, Issue 9), Ovid MEDLINE (from 1946), Ovid Embase (from 1974), PubMed (e-publications only), the Transfusion Evidence Library (from 1950), and ongoing trial databases to 12 October 2017. SELECTION CRITERIA We included RCTs, non-RCTs, and CBAs that involved the transfusion of platelet concentrates (prepared either from individual units of whole blood or by apheresis any dose, frequency, or transfusion trigger) and given to treat or prevent bleeding among people with congenital or acquired bone marrow failure disorders.We excluded uncontrolled studies, cross-sectional studies, and case-control studies. We excluded cluster-RCTs, non-randomised cluster trials, and CBAs with fewer than two intervention sites and two control sites due to the risk of confounding. We included all people with long-term bone marrow failure disorders that require platelet transfusions, including neonates. We excluded studies of alternatives to platelet transfusion, or studies of people receiving intensive chemotherapy or a stem cell transplant. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures outlined by Cochrane. Due to the absence of evidence we were unable to report on any of the review outcomes. MAIN RESULTS We identified one RCT that met the inclusion criteria for this review. The study enrolled only nine adults with MDS over a three-year study duration period. The trial was terminated due to poor recruitment rate (planned recruitment 60 participants over two years). Assessment of the risk of bias was not possible for all domains. The trial was a single-centre, single-blind trial. The clinical and demographic characteristics of the participants were never disclosed. The trial outcomes relevant to this review were bleeding assessments, mortality, quality of life, and length of hospital stay, but no data were available to report on any of these outcomes.We identified no completed non-RCTs or CBAs.We identified no ongoing RCTs, non-RCTs, or CBAs. AUTHORS' CONCLUSIONS We found no evidence to determine the safety and efficacy of therapeutic platelet transfusion compared with prophylactic platelet transfusion for people with long-term bone marrow failure disorders. This review underscores the urgency of prioritising research in this area. People with bone marrow failure depend on long-term platelet transfusion support, but the only trial that assessed a therapeutic strategy was halted. There is a need for good-quality studies comparing a therapeutic platelet transfusion strategy with a prophylactic platelet transfusion strategy; such trials should include outcomes that are important to patients, such as quality of life, length of hospital admission, and risk of bleeding.

Abstract
Background Anti-D alloimmunization can occur when platelets from RhD-positive donors are transfused to RhD-negative patients, due to red blood cell residues in the platelet concentrates. Methods Our objective was to analyze the anti-D alloimmunization rate in a selected group of women under 55 years of age diagnosed with acute leukemia over an 18-year period. We focused the analysis on RhD-negative patients who received RhD-positive platelet transfusions. Results From January 1998 to October 2016, 382 women under 55 years were diagnosed with acute leukemia. A total of 56 patients were RhD-negative, and 48 (85.7%) received RhD-positive platelets. The median number of platelet concentrates transfused per patient was 23, and 48% of all platelet transfusions were RhD-positive. The 48 RhD-negative patients received a total of 949 RhD-positive platelet concentrates. Two patients developed anti-D: a 36-year-old woman with M3 acute myeloblastic leukemia and a 52-year-old patient with a secondary acute myeloblastic leukemia. Conclusion We conclude that there is a need for agreement in the transfusion guidelines on the recommendation of anti-D alloimmunization prophylaxis. We suggest a possible benefit in favor of anti-D prophylaxis in childbearing women with acute leukemia.

Abstract
AIMS Avatrombopag, a thrombopoietin receptor agonist, is a substrate of cytochrome P450 (CYP) 2C9 and CYP3A. We assessed three drug-drug interactions of avatrombopag as a victim with dual or selective CYP2C9/3A inhibitors and inducers. METHODS This was a three-part, open-label study. Forty-eight healthy subjects received single 20 mg doses of avatrombopag alone or with one of 3 CYP2C9/3A inhibitors or inducers: fluconazole 400 mg once daily for 16 days, itraconazole 200 mg twice daily on Day 1 and 200 mg once daily on Days 2-16, or rifampicin 600 mg once daily for 16 days. Pharmacokinetics, pharmacodynamics (platelet count) and safety of avatrombopag were evaluated. RESULTS Coadministration of a single 20-mg dose of avatrombopag with fluconazole at steady-state resulted in 2.16-fold increase of AUC of avatrombopag, prolonged terminal elimination phase half-life (from 19.7 h to 39.9 h) and led to a clinically significant increase in maximum platelet count (1.66-fold). Itraconazole had a mild increase on both avatrombopag pharmacokinetics and pharmacodynamics compared to fluconazole. Coadministration of rifampicin caused a 0.5-fold decrease in AUC and shortened terminal elimination phase half-life (from 20.3 h to 9.84 h), but has no impact on maximum platelet count. Coadministration with interacting drugs was found to be generally safe and well-tolerated. CONCLUSIONS The results from coadministration of fluconazole or itraconazole suggest that CYP2C9 plays a more predominant role in metabolic clearance of avatrombopag than CYP3A. To achieve comparable platelet count increases when avatrombopag is coadministered with CYP3A and CYP2C9 inhibitors, an adjustment in the dose or duration of treatment is recommended, while coadministration with strong inducers is not currently recommended.

Abstract
Aminocaproic acid is frequently used in patients with hematologic malignancy that present with thrombocytopenia with or without hemorrhage. We conducted a retrospective study to evaluate the safety of aminocaproic acid in 109 patients with hematologic malignancies. Patients were included if aminocaproic acid had been administered for at least 24 hours for the prevention or treatment of thrombocytopenic hemorrhage. Our primary outcome was thromboembolic complications defined as arterial or venous thrombotic events objectively confirmed by imaging studies. Thromboembolic complications occurred in five patients (4.6%) and all were venous thromboses. Other than the underlying malignancy, these patients also had many concurrent risk factors including indwelling central venous catheters, which could have contributed to thromboses. In conclusion, in our population of patients with a variety of hematological malignancies, aminocaproic acid does not appear to be associated with a high incidence of thromboembolic complications.

Abstract
SummarySolving the riddle of a thrombocytopenic patient is a difficult and fascinating task. The spectrum of possible aetiologies is wide, ranging from an in vitro artefact to severe treatment-resistant thrombocytopenic bleeding conditions, or even life-threatening prothrombotic states. Moreover, thrombocytopenia by itself does not protect from thrombosis and sometimes a patient with a low platelet count requires concomitant antithrombotic treatment as well. In order to identify and treat the cause and the effects of the thrombocytopenia, you have to put together several pieces of information, solving a unique jig-jaw puzzle.The present work is not a textbook article about thrombocytopenia, rather a collection of differential diagnostic thoughts, treatment concepts, and some basic knowledge, that you can retrieve when facing your next thrombocytopenic patient. Enjoy reading it, but most importantly enjoy taking care of patients with a low platelet count. I bet the present work will assist you in this challenging and rewarding clinical task.
