This study aimed to evaluate the efficacy and safety of tailored doses of vWF/FVIII concentrate according to intervention-associated bleeding risk in vWD patients undergoing surgery.Methods: This was a retrospective analysis of vWD patients who underwent surgical procedures at a haemophilia centre. Patients received vWF/FVIII concentrate with dosage and duration of treatment dependent on intervention type (dental, gynaecological, abdominal or orthopaedic/traumatic) and bleeding risk (moderate/high).Results: Eighty-three surgical procedures (42 patients) were included. Median preoperative loading doses of vWF/FVIII concentrate were 29.9 IU/kg and 35.7 IU/kg for interventions with moderate ( n = 16) or high ( n = 67) bleeding risk, respectively. The median perioperative dose was highest in orthopaedic or trauma-related surgery (140 IU/kg) and lowest in dental or gynaecological interventions (76.4 IU/kg and 80.0 IU/kg, respectively). During follow-up, no bleeding or other complications were observed in 95% of patients.Conclusions: Individually tailored doses of vWF/FVIII concentrate according to intervention-associated bleeding risk were effective in preventing postoperative bleeding, with few complications observed. These doses may be used as guidance in routine clinical care.","PeriodicalId":8992,"journal":{"name":"Blood Coagulation & Fibrinolysis","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139097152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included genetically confirmed congenital dysfibrinogenemia cases (n = 63) and healthy controls ( n = 50). EXTEM, INTEM, FIBTEM tests were used to measure ROTEM parameters, that is, clotting time (CT), clot formation time (CFT), maximal clot firmness (MCF) and amplitude 10 min after CT (A10). The ISTH bleeding assessment tool was used to determine bleeding episodes. CT (INTEM) was statistically significantly shorter in congenital dysfibrinogenemia patients compared to controls while CFT (EXTEM) was prolonged. Patients's MCF in EXTEM, INTEM, and FIBTEM were similar to controls while A10 (FIBTEM) was statistically significantly lower. Fibrinogen activity was positively correlated with fibrinogen antigen, A10 and MCF in all three assays. Bleeding phenotypes were observed in 23 (36.5%) patients. Only CFT in EXTEM and CT in INTEM were statistically different in patients with bleeding phenotype versus controls. Carriers of the FGA mutation p.Arg35His had a CT (EXTEM) slightly prolonged and a reduced A10 (FIBTEM) compared to controls. Some ROTEM parameters were able to distinguish congenital dysfibrinogenemia patients from controls, and patients with a bleeding phenotype. Prolonged CFT in EXTEM were associated with congenital dysfibrinogenemia and bleeding phenotype. Bleeding episodes in most patients were generally mild and prevalence of thrombosis was very low.","PeriodicalId":8992,"journal":{"name":"Blood Coagulation & Fibrinolysis","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10927300/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139511465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is synthesized by the liver and belongs to the serine protease inhibitors, which are commonly referred to as the SERPINS superfamily. The antithrombin molecule comprises 432 amino acids and has a molecular weight of approximately 58 200 D. It consists of three domains, including an amino-terminal domain, a carbohydrate-rich domain, and a carboxyl-terminal domain. The amino-terminal domain binds with heparin, whereas the carboxyl-terminal domain binds with serine protease. Antithrombin is a crucial natural anticoagulant that contributes approximately 60-80% of plasma anticoagulant activities in the human body. Moreover, antithrombin has anti-inflammatory effects that can be divided into coagulation-dependent and coagulation-independent effects. Furthermore, it exhibits antitumor activity and possesses a broad range of antiviral properties. Inherited type I antithrombin deficiency is a quantitative disorder that is characterized by low antithrombin activity due to low plasma levels. On the other hand, inherited type II antithrombin deficiency is a qualitative disorder that is characterized by defects in the antithrombin molecule. Acquired antithrombin deficiencies are more common than hereditary deficiencies and are associated with various clinical conditions due to reduced synthesis, increased loss, or enhanced consumption. The purpose of this review was to provide an update on the structure, functions, clinical implications, and methods of detection of antithrombin.","PeriodicalId":8992,"journal":{"name":"Blood Coagulation & Fibrinolysis","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139097240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mixing corrected most prolonged PT samples (93%), but 32 cases showed incomplete correction. Of these 32 cases, 18 were confounded by DOAC use, and 3 by factor V (FV) inhibitor. We observed an unusual pattern of prolongation of aPTT after incubation, which was previously considered a characteristic of specific factor inhibitors, most commonly FVIII inhibitor. However, we found that lupus anticoagulant (28%) and DOAC (25%) contributed to this pattern similarly as specific factor inhibitors (28%).

There was a strong and significant correlation between the DIC score and the parameters max1, max2 and max1' and a very strong and significant correlation between fibrinogen levels and max1, max2 and max1'. When comparing DIC patients with hypofibrinogenemia and DIC without hypofibrinogenemia, a significant difference was noted in max1, max2, Tmax1 and Tmax2.

However, a few studies evaluated the utility of ISTH-BAT in diagnosing patients with platelet function defects (PFDs). In this study, we evaluated the diagnostic utility of ISTH-BAT in predicting PFDs among patients suspected of PFDs. Forty patients suspected of PFDs and 21 normal healthy controls were evaluated by the ISTH-BAT scoring system, light transmission aggregometry (LTA), ATP-releasing assays (lumi-aggregometry), and expression of CD62P for diagnosis of PFDs. Among 40 patients suspected of PFDs, 10 were diagnosed as PFDs using lumiaggregometry and CD62P. The ISTH-BAT score in patients suspected of PFDs [(6, interquartile range (IQR) 1-8] and patients with PFDs was significantly higher than the control group (0; IQR 0-0) ( P < 0.001). Receiver operating characteristic curves indicate that ISTH-BAT is not able to discriminate patients with PFDs from those without PFDs (areas under the curve of 0.620 (95% confidence interval 0.415-0.825). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the ISTH-BAT in predicting the presence of PFDs, respectively, were 40, 73.3, 33.3, and 78.6% in the cut-off ISTH-BAT at least 4 in adult men, at least 6 in adult women, and at least 3 in children (age < 18).
