32550069 Patients’ resistance to prophylactic doses of heparin could be due to low levels of anti-thrombin and high levels of fibrinogen, which would reinforce the use of therapeutic doses of heparin in the early stages of hospitalization.
32551814 Hypercoagulability and systemic thrombotic complications necessitate anticoagulant and thrombolytic interventions, which provide opportunities to prevent or reduce “excessive” thrombin generation, while preserving “adaptive” hemostasis and bring additional benefit via their anti-inflammatory effect in the setting of COVID-19.
32558620 Although thrombosis initiated by the innate immune system is hypothesized to limit SARS-CoV-2 dissemination, aberrant activation of this system can cause endothelial injury resulting in loss of thromboprotective mechanisms, excess thrombin generation, and dysregulation of fibrinolysis and thrombosis.
32581015 Thrombin Time (TT), Prothrombin Time (PT), Fibrinogen (FIB), Activated Partial Thromboplastin Time (APPT), and D-Dimer have been detected as parameters to study in every COVID-19 patient.
32586214 However, in patients with COVID-19 the subsequent endothelial inflammation, complement activation, thrombin generation, platelet and leukocyte recruitment, and the initiation of innate and adaptive immune responses culminate in immunothrombosis, ultimately causing (micro)thrombotic compli¬cations such as deep vein thrombosis, pulmonary embolism and stroke.

32668058 We aimed to assess fibrinolytic activity and thrombin generation in 78 Covid-19 patients. […] We measured fibrinolytic parameters (tissue plasminogen activator, PAI-1, thrombin activatable fibrinolysis inhibitor, alpha2 anti-plasmin, and tissue plasminogen activator-modified ROTEM device), thrombin generation, and other coagulation tests (D-dimer, fibrinogen, factor VIII, antithrombin). […] We observed two key findings: a high thrombin generation capacity that remained within normal values despite heparin therapy and a hypofibrinolysis mainly associated with increased PAI-1 levels.
32687449 Viral coagulopathy is not novel given similar observations with SARS classic, including the consumption of platelets, generation of thrombin, and increased fibrin degradation product exhibiting overt disseminated intravascular coagulation-like syndrome.
32695551 1.06 (1.01-1.13), p = 0.000; thrombin time (TT) 16.35 (15.69-17.47) s vs. 
32759504 Here, we investigated how complement interacts with the platelet/neutrophil extracellular traps (NETs)/thrombin axis, using COVID-19 specimens, cell-based inhibition studies, and NET/human aortic endothelial cell (HAEC) cocultures. […] Thrombin or NETosis inhibition or C5aR1 blockade attenuated platelet-mediated NET-driven thrombogenicity.
32762118 Despite detectable anti-activated factor X activity in the majority of patients, ex vivo thrombin generation was normal, and in vivo thrombin generation elevated as evidenced by elevated levels of thrombin-antithrombin complexes and D-dimers.

32860301 The authors stress on the large variability observed between different anti-Xa kits available on the market, they contest our results of thrombin generation assay (TGA) in patients with COVID-19 receiving standard- or high-dose prophylaxis and question the relevance of thromboelastography as a global haemostasis assay.
32870433 Thrombin is a trypsin-like serine protease with multiple physiological functions. […] Nevertheless, thrombin also plays a major role in inflammation by activating protease-activated receptors. […] In addition, thrombin is also involved in angiogenesis, fibrosis, and viral infections. […] Considering the pathogenesis of COVID-19 pandemic, thrombin inhibitors may exert multiple potential therapeutic benefits including antithrombotic, anti-inflammatory, and antiviral activities. […] In this review, we describe the clinical features of COVID-19, the thrombin’s roles in various pathologies, and the potential of argatroban in COVID-19 patients. […] Argatroban is a synthetic, small molecule, direct, competitive, and selective inhibitor of thrombin.
32879103 Among them, laboratory tests included white blood cell (WBC), lymphocytes (LYM), neutrophil (NEU), hemoglobin (Hb), platelet (PLT), prothrombin time (PT), plasma fibrinogen (Fib), activated partial prothrombin time (APTT), thrombin time (TT), D-dimer, total bilirubin (TBIL), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), serum creatinine (Cr), creatine kinase (CK), creatine kinase isoenzyme-MB (CK-MB), lactate dehydrogenase (LDH), C-reactive protein (CRP), and oxygen partial pressure in arterial blood.
32892505 The aim was to further characterize thrombin generation using a novel analyser (ST Genesia, Diagnostica Stago, Asnières, France) and a panel of haematological analytes in patients with COVID-19. […] Thrombin generation, in critical patients, was right shifted without significant differences in peak, velocity index or endogenous thrombin potential. […] Importantly, disease severity did not increase thrombin generation (including thrombin-antithrombin complexes and prothrombin fragment 1 + 2) when comparing both cohorts; counter-intuitively critical patients were hypocoaguable. tPA, TFPI and VEGF were increased in critical patients, which are hypothesized to reflect endothelial dysfunction and/or contribution of heparin (which may cause endothelial TFPI/tPA release).
32899532 COVID-19 patients had moderately high levels of thrombin-antithrombin complex and plasmin-alpha2-plasmin inhibitor complex but normal plasminogen activator inhibitor-1 level.
32905282 Careful attention to his daily platelet count suggested the possibility of immune mediated heparin-induced thrombocytopenia (HIT) which was confirmed by laboratory testing and resolved when anticoagulation was switched to a direct thrombin inhibitor.
32918208 FXa is known to activate prothrombin to thrombin, which eventually leads to the formation of cross-linked blood clots. […] While this process is important in maintaining hemostasis, excessive thrombin generation results in a host of thrombotic conditions.

32938299 Functionally, platelets were hyperactivated in COVID-19 subjects presenting non-severe and severe symptoms, with aggregation occurring at suboptimal thrombin concentrations.
32945081 In particular, procoagulant platelets support thrombin generation and mediate thromboinflammation. […] We observed that platelets isolated from COVID-19 patients had a reduced ability to become procoagulant compared to those from matched healthy donors, as evidenced by reduced mitochondrial depolarization and phosphatidylserine exposure following dual stimulation with thrombin and convulxin.
32946915 Endothelial dysfunction plays an important role in the coagulation disorders via increased generation of the thrombin and stops fibrinolysis further leads to hypercoagulopathy.

33016666 Taking also into considerations its anti-inflammatory and thrombin-inhibitory actions, a bioavailable form of quercetin, like Quercetin Phytosome®, should be considered a possible candidate to clinically face COVID-19.
33030036 Clotting assays (PiCT, aPTT, PT and TT), anti-Xa and anti-IIa and thrombin generation studies were carried out. […] In the thrombin generation assay, FMH and UFH produced comparable inhibition of thrombin generation as measured by various parameters.
33030047 We found the prothrombin time (PT), thrombin time (TT), D-dimer were significantly higher in the severe group (P < 0.05), and the highest area under the curve (AUC) is 0.91 for D-dimer, while the AUC of PT and TT were 0.80 and 0.61 respectively.
33034398 On the basis of the clinical COVID-19 manifestations, the multifaceted aspect of quercetin as both antiinflammatory and thrombin-inhibitory actions, should be taken into consideration.

33124941 These responses result in increased signaling by thrombin (proteinase-activated) and purinergic receptors, which promote platelet activation and exert pathological effects on other cell types (e.g., endothelial cells, epithelial cells, fibroblasts), further enhancing inflammation and injury. […] Inhibitors of thrombin and purinergic receptors may thus have therapeutic effects by blunting platelet-mediated thromboinflammation and dysfunction in other cell types.
33126772 Severe patterns of COVID-19 ARDS are characterized by a thrombin burst and the consequent coagulation activation.
33196292 We measured biomarkers of endogenous coagulation and fibrinolytic activity by immunoassays, thrombin, and plasmin generation potential by fluorescence and fibrin formation and lysis by turbidity. […] Patients with COVID-19 had increased thrombin generation potential despite prophylactic anticoagulation, whereas patients with sepsis did not. […] The collective perturbations in plasma thrombin and plasmin generation permitted enhanced fibrin formation in both COVID-19 and sepsis. […] Unexpectedly, the lag times to thrombin, plasmin, and fibrin formation were prolonged with increased disease severity in COVID-19, suggesting a loss of coagulation-initiating mechanisms accompanies severe COVID-19.
33200086 We report temporal changes of plasma levels of an extended set of laboratory parameters during the ICU stay of the 21 COVID-19 patients included in the monocentre cohort: CRP, platelet count, prothrombin time; Clauss fibrinogen and clotting factors II, V and VIII levels, D-dimers, antithrombin activity, protein C, free protein S, total and free tissue factor pathway inhibitor, PAI-1 levels, von Willebrand factor antigen and activity, ADAMTS-13 (plasma levels); and of two integrative tests of coagulation (thrombin generation with ST Genesia) and fibrinolysis (global fibrinolytic capacity - GFC).

33302737 Thrombin is the key regulator of coagulation and fibrin formation. […] In severe COVID-19, a dysfunctional of physiological anticoagulant mechanisms leads to a progressive increase of thrombin activity, which is associated with acute respiratory distress syndrome development and a poor prognosis. […] Protease-activated receptor type 1 (PAR1) is the main thrombin receptor and may represent an essential link between coagulation and inflammation in the pathophysiology of COVID-19.
33332362 In a retrospective single-center analysis at the University Hospital Zurich, Switzerland, we investigated 31 adult COVID-19 patients between April 6th and May 13th, 2020 and with at least one laboratory assessment of the coagulation markers prothrombin time/Quick, thrombin time, fibrinogen and D-dimers.
33389440 The high specificity of aptamers with small-molecule targets (metal ions, dyes and theophylline; ATP) is within 1 pM and 1 μM range, whereas with the proteins (thrombin, CD4 and antibodies) it is in the nanomolar range (which is equivalent to monoclonal antibodies).

33421462 The development of lung coagulopathy involves thrombin generation and fibrinolysis inhibition.
33423804 Dysregulated innate immune response in the lung due to viral-entry mediated angiotensin-I-converting enzyme 2 (ACE2) receptor downregulation causes endothelial injury in the pulmonary vasculature, inflammatory cytokine release, increased thrombin generation and impaired fibrinolysis.
33480807 Further, direct thrombin inhibitors and platelet inhibitors in a patient-specific manner should also be considered.
33509706 Velocity curves were consistent with increased generation of thrombin. […] In patients with COVID-19, TEG demonstrates a complex and prolonged hypercoagulable state including fast initiation of coagulation and clot reinforcement, low fibrinolysis, high potential of thrombin generation, and high fibrinogen and platelet contribution.
33537537 Patients with COVID-19 with higher respiratory support had increased in vivo activation of coagulation and fibrinolysis, as reflected by higher plasma levels of d-dimer, thrombin-antithrombin, and plasmin-antiplasmin complexes as compared to patients with no to minimal respiratory support and healthy controls. […] Moreover, the patients with COVID-19 with higher respiratory support exhibited substantial ex vivo thrombin generation and lower ex vivo fibrinolytic capacity, despite higher doses of anticoagulant therapy compared to less severely ill patients.
33544518 Thrombin generation (TG) with and without thrombomodulin (TM) was evaluated in COVID-19 patients with different disease severity and thromboprophylaxis regimen, in order to understand the prothrombotic profile. […] Overall, patients with COVID-19 showed a TG profile comparable to that of healthy subjects (i.e. comparable peak height, endogenous thrombin potential [ETP] with and without TM).
33544720 These top-ranked drugs include ACE-inhibitors, monoclonal antibodies (e.g., anti-IFNγ, anti-TNFα, anti-IL12, anti-IL1β, anti-IL6), and thrombin inhibitors.
