RATIONALE: Ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia (EDTA-PTCP) is a rare phenomenon characterized by spuriously low platelet counts when EDTA reacts with harvested blood. However, to the best of our knowledge, only two cases involving EDTA-PTCP in postoperative patients with sepsis have been reported. Here, we describe a case of EDTA-PTCP that appeared transiently in a postoperative patient with sepsis. PATIENT CONCERNS: A 68-year-old female patient underwent laparoscopic tension-free hernioplasty for incisional hernia...

BACKGROUND: The optimal management of anticoagulation in hemodialyzed patients with a high risk of bleeding is controversial. METHODS: We compared premature termination of dialysis caused by clotting events between AN69ST membranes (G1) and 0.8 mmol/L citrate-enriched dialysate (G2). The number of sessions that had increased venous pressure (VP) and variations in urea-reduction ratio (URR) were analyzed. RESULTS: Six hundred and two sessions were analyzed in 259 patients: 22...

BACKGROUND: In regenerative therapy, self-clotted platelet concentrates, such as platelet-rich fibrin (PRF), are generally prepared on-site and are immediately used for treatment. If blood samples or prepared clots can be preserved for several days, their clinical applicability will expand. Here, we prepared PRF from stored whole-blood samples and examined their characteristics. METHODS: Blood samples were collected from non-smoking, healthy male donors (aged 27-67 years, N = 6), and PRF clots were prepared immediately or after storage for 1-2 days...

BACKGROUND: Regional citrate anticoagulation (RCA) is proposed for various extracorporeal purification techniques to overcome the risk of bleeding that might result from systemic anticoagulation. Yet, no individualized treatment protocol has been proposed for therapeutic plasma exchange (TPE) so far. The objective of this study was to assess the determinants of blood citrate concentration needed and to develop an individualized RCA protocol useful for clinical practice. METHODS: The study population included 14 patients who underwent a total of 47 TPE sessions...

BACKGROUND: Clotting of continuous renal replacement therapy (CRRT) circuits leads to inadequate clearance, decreased ultrafiltration, and increased resource use. We identified factors associated with premature clotting of circuits during CRRT in children. METHODS: In a retrospective cohort of 26 children (median age 11.8 years) receiving 79 CRRT circuits (51 heparin, 22 citrate, 6 using no anticoagulation), we captured hourly pressure, flow, and fluid removal rates along with all activated clotting time (ACT) and circuit ionized calcium measurements...

AIMS: To evaluate the efficacy and safety of a commercially available phosphate-containing solution for continuous renal replacement therapy (CRRT) in preventing CRRT-related hypophosphatemia. METHODS: In heart surgery patients undergoing continuous veno-venous haemodiafiltration (CVVHDF) with regional citrate anticoagulation (RCA), we combined an 18 mmol/l citrate solution with a phosphate-containing (1.2 mmol/l) dialysate/replacement fluid evaluating the incidence of hypophosphatemia and the need for parenteral phosphorus supplementation...

INTRODUCTION: Regional anticoagulation with citrate has been found to be superior to heparin in terms of biocompatibility, and numerous protocols for regional citrate anticoagulation have been published, while a consensus on the target concentration of ionized calcium (Ca2+) in the extracorporeal circuit has not been reached so far. METHODS: The aim of this in vitro study was to assess the impact of different citrate concentrations on coagulation as well as on complement activation and cytokine secretion and to investigate the impact of ionized magnesium (Mg2+) on these parameters...

Staphylococcal superantigen-like proteins (SSLs) are a family of exoproteins of Staphylococcus aureus. We have shown that SSL10 binds to vitamin K-dependent coagulation factors and inhibits blood coagulation induced by recalcification of citrated plasma. SSL10 was revealed to bind to coagulation factors via their γ-carboxyglutamic acid (Gla) domain. In this study we attempted to identify the responsible sequence of SSL10 for the interaction with coagulation factors. We prepared a series of domain swap mutants between SSL10 and its paralog SSL7 that does not interact with coagulation factors, and examined their binding activity to immobilized prothrombin using ELISA-like binding assay...

The knowledge of pseudothrombocytopenia (PTCP) is important for the accuracy of a clinical assessment and for avoiding unnecessary treatment. An elderly patient was hospitalized with left lung pneumonia. Severe thrombocytopenia [platelet (PLT) number: 18 × 10(9)/L] without any clinical bleeding was found in ethylenediaminetetraacetic acid blood collection tube. PLT measurement was repeated in various anticoagulant [sodium citrate, lithium heparin, disodium oxalate, hirudin, and magnesium sulfate (Mg-sulfate)] sample collection tubes and all of them showed thrombocytopenia except with Mg-sulfate...

Platelet-rich plasma has been studied extensively in dogs, but validation of enzyme-linked immunosorbent assays (ELISAs) for quantifying anabolic growth factors and inflammatory cytokines in canine plasma prepared with citrate-based anticoagulants is not available. We performed a validation of commercial ELISAs for transforming growth factor-beta 1 (TGF-β1), platelet-derived growth factor-BB (PDGF-BB), vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-α), and interleukin-1 beta (IL-1β) for use with canine plasma prepared with acid-citrate-dextrose, solution A (ACD-A)...

BACKGROUND: The aim of this study is to determine whether and how the anticoagulant agents EDTA, sodium citrate, and heparin present in vacutainers and CPDA located in transfusion bags modify peripheral blood cell behavior. METHODS: We compared the effect of four anticoagulants within an expression study quantifying mRNA by realtime PCR in 60 blood samples. RESULTS: We observed a significant increase of TNFα and CCL2 mRNA expression in leukocytes placed in EDTA anticoagulant compared to leukocytes collected with citrate or heparin (p ≤ 0...

BACKGROUND: During the course of acute kidney injury (AKI) patients may require renal replacement therapy (RRT). The preferred therapeutic measure for such patients is continuous RRT (CRRT). Anticoagulation is required to prevent clotting of the extracorporeal circuit. The actual KDIGO guidelines recommend citrate as the first line anticoagulant. METHODS: Citrate dose infused into the extracorporeal circuit should achieve an extracorporeal calcium concentration of 0...

BACKGROUND AND AIM: The potential of microRNAs (miRNA) as non-invasive diagnostic, prognostic, and predictive biomarkers, as well as therapeutic targets, has recently been recognized. Previous studies have highlighted the importance of consistency in the methodology used, but to our knowledge, no study has described the methodology of sample preparation and storage systematically with respect to miRNAs as blood biomarkers. The aim of this study was to investigate the stability of miRNAs in blood under various relevant clinical and research conditions: different collection tubes, storage at different temperatures, physical disturbance, as well as serial freeze-thaw cycles...

In this study, the binding of a glycosylated serine protease (EuP-82) with human fibrinogen was investigated by the isothermal titration calorimetry (ITC). The ITC analysis indicated that the binding of EuP-82 to fibrinogen in the conditions with or without the activator (Ca(2+) ) was an exothermic reaction (dominant negative enthalpy), which tended to be driven by hydrogen bonding and van der Waals interactions. In contrast, the binding of fibrinogen-EuP-82 in the condition with the inhibitor (Zn(2+) ) was an unfavorable endothermic reaction...

BACKGROUND: Platelet clumping is a common occurrence during peripheral blood hematopoietic stem cell (HSC) collection using the Spectra Optia mononuclear cell (MNC) protocol. If clumping persists, it may prevent continuation of the collection and interfere with proper MNC separation. This study is the first to report the incidence of clumping, identify precollection factors associated with platelet clumping, and describe the degree to which platelet clumping interferes with HSC product yield...

Acute kidney injury (AKI) is a common complication in the critically ill. Current standard of care mainly relies on identification of patients at risk, haemodynamic optimization, avoidance of nephrotoxicity and the use of renal replacement therapy (RRT) in established AKI. The detection of early biomarkers of renal tissue damage is a recent development that allows amending the late and insensitive diagnosis with current AKI criteria. Increasing evidence suggests that the consequences of an episode of AKI extend long beyond the acute hospitalization...

The anticoagulant mostly employed for platelet count is EDTA. The Francophone Group of Cellular Hematology recommends checking of blood smear stained with May-Grünwald Giemsa any thrombocytopenia less than 100 G/L without medical history or whether an alarm is generated by the cell counter. The pseudo-thrombocytopenia (PTP) with EDTA is the best known artifact in platelet count. A sample of blood on citrated tube is necessary to get rid of the interference. The objective of this study was to compare the platelet counts obtained on EDTA (numEDTA) and citrate (numCTAD) tubes and to define, then validate a factor of conversion between both methods...

Effective delivery of continuous renal replacement therapy (CRRT) depends on the longevity of the filter and circuit used in the CRRT machine. Safe and effective anticoagulation is crucial for maintaining the patency of these circuits. In children, heparin and citrate are the commonly used anticoagulants but they are limited by serious side effects and thus calls for meticulous monitoring. In conditions where neither of these can be used, prostacyclin can be an effective alternative. Prostacyclin is a platelet inhibitor that can be safely used as an efficient anticoagulant in CRRT...
