The aim of this study was to determine if sodium-citrate plasma is a suitable substitute for serum for cardiac troponin I (cTnI) measurement using the Beckman ACCESS 2 immunoassay. Linear regression analysis of cTnI levels in paired serum and sodium-citrate plasma samples from 80 patients provided a y-intercept of -0.0193 and a slope of 1.044. The correlation was good [r=0.995; 95% confidence interval 1.017 to 1.068, p <0.0001]. The paired results were not significantly different by Student's t-test. Serum and sodium-citrate plasma appear to be interchangeable as samples for cTnI measurement using the ACCESS 2 assay. Furthermore, the use of plasma reduces the turnaround time and may avoid false positive cTnI results due to residual fibrin.

Aortic valve calcification results from degenerative processes associated with several pathologies. These processes are influenced by age, chronic inflammation, and high concentrations of phosphate ions in the plasma, which contribute to induce mineralization in the aortic valve and deterioration of cardiovascular health. Environmental factors, such as wood smoke that emits harmful and carcinogenic pollutants, carbon monoxide (CO), and nitrogen oxide (NO), as well as other reactive compounds may also be implicated.

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) influenced by multiple factors. Berberine, an isoquinoline alkaloid derived from the root and bark of Franch., has shown promise in managing UC, but its underlying mechanisms remain unclear.

Hemophilia A (HA) patients under emicizumab prophylaxis may require the concomitant use of procoagulant factors for breakthrough bleedings or immune tolerance induction (ITI). The aim of this study is to evaluate the ex vivo procoagulant effect of plasma-derived FVIII concentrates containing von Willebrand factor (pdFVIII/VWF) in samples from patients with severe HA without inhibitors on emicizumab prophylaxis. Samples from healthy controls (HC) and HA patients were drawn in sodium citrate plus corn trypsin inhibitor tubes and spiked with increasing concentrations of pdFVIII/VWF concentrates (10-400 IU/dL) (Fanhdi/Alphanate, Grifols), activated prothrombin complex concentrate (aPCC, 0.

Enhanced fibrinolysis or hyperfibrinolysis may lead to life-threatening blood loss, while reduced activity may contribute to thrombosis. Euglobulin clot lysis time (ECLT) is a manual method that measures plasma fibrinolytic activity and is considered the gold standard. However, the data on reference interval is scarce and outdated.

Background: Therapeutic plasma exchange (TPE) is an important blood purification technology and most patients require multiple consecutive TPEs. Regional citrate anticoagulation (RCA) could be used for membrane therapeutic plasma exchange (mTPE). However, there is no research on the metabolic complications of the RCA for patients receiving multiple consecutive mTPEs with fresh frozen plasma (FFP) as a replacement solution.
