The delayed platelet engraftment associated with allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a common complication and often results in increased transplant-related complications...
Platelet transfusions are used across multiple patient populations to prevent and correct bleeding. This scoping review aimed to map the currently available systematic reviews (SRs) and evidence-based...
A systematic literature search was conducted in seven databases for SRs on effectiveness (including dose and timing, transfusion trigger and ratio to other blood products), production modalities and d...
We identified 110 SRs. The majority focused on clinical effectiveness, including prophylactic or therapeutic transfusions compared to no platelet transfusion (34 SRs), prophylactic compared to therape...
An interactive evidence map of SRs and evidence-based guidelines in the field of platelet transfusion has been developed and identified multiple reviews. This work serves as a tool for researchers loo...
Administering platelets through a rapid infuser is proven to be safe. However, the clinical significance of infusing ABO-incompatible platelets with red blood cells (RBCs) in a rapid infuser remains u...
Seven in vitro studies were performed including five cases (type A RBCs and type O platelets) and two controls (type A RBCs and platelets). Anti-A titers were measured in platelet units. An RBC unit a...
The post-mix DAT was positive for IgG in all test samples (5/5), and weakly positive for complement in 3/5. The changes in free Hb in test cases between measured and calculated post-mix spanned -2.2 t...
Our study suggested that mixing ABO-incompatible platelets with RBCs in a rapid infuser does not induce in vitro hemolysis. These findings support the use of rapid infusers regardless of platelet comp...
The aims of this study were to observe the therapeutic effect of platelet (PLT) transfusion and to analyze influencing factors for the sake of providing useful clues for improving the efficacy of PLT ...
Included in this study were patients who received PLT transfusion in the affiliated hospital of Nantong University. Patients' sex, age, height, weight, PLT transfusion status, and 20-24-h PLT count be...
A total of 364 patients received 1,060 PLT transfusions, including 728 successful transfusions and 332 unsuccessful transfusions. When the patients were grouped according to different etiologies, sign...
To reduce PTR, multiple factors should be considered comprehensively when PLT transfusion therapy is to be implemented in clinical practice. PLT antibody is the main immune factor causing PTR....
Following the results of the PlaNeT-2 randomized controlled trial showing decreased morbidity and mortality in neonates transfused at a threshold of 25 versus 50 × 10...
Prospective observational cohort chart-review study comparing all neonates consecutively admitted to the NICU during two 5-months periods: 2013 (before; N = 401) versus 2021 (after; N = 402). Possible...
Mean (± standard deviation) gestational age and birth weight were 34.9 ± 4.2 weeks and 2.5 ± 1.0 kg, respectively. In 2021, 5.0% were platelet-transfused versus 9.2% in 2013 (p = .027). Platelet trans...
Restrictive local transfusion thresholds in a NICU decreased the proportion of platelet-transfused neonates by 46% and reduced donor exposure in transfused patients....
Platelet transfusion refractoriness due to HLA alloimmunization presents a significant medical problem, particularly among multiply transfused patients with hematologic malignancies and those undergoi...
Assess mortality and neurodevelopmental outcomes at 2 years of corrected age in children who participated in the PlaNeT-2/MATISSE (Platelets for Neonatal Transfusion - 2/Management of Thrombocytopenia...
Randomised clinical trial, enrolling from June 2011 to August 2017. Follow-up was complete by January 2020. Caregivers were not blinded; however, outcome assessors were blinded to treatment group....
43 level II/III/IV neonatal intensive care units (NICUs) across UK, Netherlands and Ireland....
660 infants born at less than 34 weeks' gestation with platelet counts less than 50×10...
Infants were randomised to undergo a platelet transfusion at platelet count thresholds of 50×10...
Our prespecified long-term follow-up outcome was a composite of death or neurodevelopmental impairment (developmental delay, cerebral palsy, seizure disorder, profound hearing or vision loss) at 2 yea...
Follow-up data were available for 601 of 653 (92%) eligible participants. Of the 296 infants assigned to the higher threshold group, 147 (50%) died or survived with neurodevelopmental impairment, as c...
Infants randomised to a higher platelet transfusion threshold of 50×10...

Transfusion-related acute lung injury (TRALI) is a severe complication of blood transfusion that is thought of as a two-hit event: first the underlying patient condition (e.g., sepsis), and then the t...
In a randomized controlled trial, 18 healthy male volunteers received a first hit of experimental endotoxemia (2 ng/kg lipopolysaccharide), and a second hit of fresh (2-day old) or aged (7-day old) au...
All subjects reacted adequately to lipopolysaccharide infusion and satisfied SIRS criteria (increased pulse [>90/min] and temperature [>38°C]). There were no differences between the saline, fresh, and...
In a human endotoxemia model of autologous platelet transfusion, with an adequate first hit and platelet storage lesion, transfusion of 7-day-old PC does not increase pulmonary inflammation compared w...
The short shelf-life of liquid-stored platelets (LP) at 20-24°C poses shortage and wastage challenges. Cryopreserved platelets have significantly extended shelf-life, and were safe and efficacious for...
We performed a phase 1b/2a randomized cross-over study comparing the safety and efficacy of cryopreserved buffy coat-derived pooled platelets (CP) to LP in the prophylactic transfusions of thrombocyto...
A total of 18 adults were randomly assigned 1:1 to CP and LP for their first thrombocytopenic period (TP) of up to 28-days. A total of 14 crossed over to the other platelet-arm for the second TP. Over...
During shortages, CP may supplement LP in prophylactic transfusions of thrombocytopenic patients....
We report Listeria monocytogenes infection in a patient in Italy who was transfused with pooled platelet concentrate. Genomic analysis revealed that L. monocytogenes isolates from the donor blood unit...
