Abstract
Thrombosis is a multifaceted process involving various molecular components, including the coagulation cascade, platelet activation, platelet-endothelial interaction, anticoagulant signaling pathways, inflammatory mediators, genetic factors and the involvement of various cells such as endothelial cells, platelets and leukocytes. A comprehensive understanding of the molecular signaling pathways and cell interactions that play a role in thrombosis is essential for the development of precise therapeutic strategies for the treatment and prevention of thrombotic diseases. Ongoing research in this field is constantly uncovering new molecular players and pathways that offer opportunities for more precise interventions in the clinical setting. These molecular insights into thrombosis form the basis for the development of targeted therapeutic approaches for the treatment and prevention of thrombotic disease. The aim of this review is to provide an overview of the pathogenesis of thrombosis and to explore new therapeutic options.

Rosuvastatin treatment decreases plasma procoagulant phospholipid activity after a VTE: A randomized controlled trial. J Thromb Haemost 2022; 20:877-887.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a frequent cardiovascular disease with severe complications, including recurrence and death. There is a great need for alternative prophylactic treatment options as anticoagulation is accompanied by increased bleeding risk. Statins are reported to reduce the risk of incident and recurrent VTE, but the mechanisms are elusive. Procoagulant phospholipids (PPL), and phosphatidylserine in particular, are crucial for efficient coagulation activation, but no studies have investigated the effect of statin treatment on plasma PPL activity. OBJECTIVES To investigate the impact of rosuvastatin treatment on plasma PPL activity and levels of extracellular vesicles (EVs). PATIENTS/METHODS Patients with a history of VTE (≥18 years) allowed to stop anticoagulant treatment were randomized to either 20 mg/day of rosuvastatin treatment or no treatment for 28 days in the Statins Reduce Thrombophilia (NCT01613794) trial. Plasma samples were collected at baseline and study end. PPL activity was measured in samples from 245 participants using a factor Xa-dependent clotting assay and EV levels by flow cytometry. RESULTS Rosuvastatin treatment yielded an overall 22% (95% confidence interval [CI] -38.2 to -5.8) reduction in PPL activity, and 37% (95% CI -62.9 to -11.2) reduction in PPL activity in participants with a history of pulmonary embolism. The effect of rosuvastatin on plasma PPL activity was not explained by changes in total cholesterol nor change in levels of total- or platelet-derived EVs. CONCLUSIONS Rosuvastatin treatment caused a substantial decrease in plasma PPL activity, suggesting that a PPL-dependent attenuation of coagulation activation may contribute to a reduced VTE risk following statin treatment.

Abstract
BACKGROUND Negatively charged procoagulant phospholipids, phosphatidylserine (PS) in particular, are vital to coagulation and expressed on the surface membrane of extracellular vesicles. No previous study has investigated the association between plasma procoagulant phospholipid clotting time (PPLCT) and future risk of venous thromboembolism (VTE). OBJECTIVES To investigate the association between plasma PPLCT and the risk of incident VTE in a nested case-control study. METHODS We conducted a nested case-control study in 296 VTE patients and 674 age- and sex-matched controls derived from a general population cohort (The Tromsø Study 1994-2007). PPLCT was measured in platelet-free plasma using a modified factor Xa-dependent clotting assay. Logistic regression was used to estimate odds ratio (OR) with 95% confidence intervals (CI) for VTE with PPLCT modelled as a continuous variable across quartiles and in dichotomized analyses. RESULTS There was a weak inverse association between plasma PPLCT and risk of VTE per 1 standard deviation increase of PPLCT (OR 0.93, 95% CI 0.80-1.07) and when comparing those with PPLCT in the highest quartile (OR 0.89, 95% CI 0.60-1.30) with those in the lowest quartile. Subjects with PPLCT >95th percentile had substantially lowered OR for VTE (OR 0.35, 95% CI 0.13-0.81). The inverse association was stronger when the analyses were restricted to samples taken shortly before the event. The risk estimates by categories of plasma PPLCT were similar for deep vein thrombosis and pulmonary embolism. CONCLUSION Our findings suggest that high plasma PPLCT is associated with reduced risk of VTE.

Abstract
Extracellular vesicles (EVs) compose a heterogenous group of membrane-derived particles, including exosomes, microvesicles and apoptotic bodies, which are released into the extracellular environment in response to proinflammatory or proapoptotic stimuli. From earlier studies suggesting that EV shedding constitutes a cellular clearance mechanism, it has become evident that EV formation, secretion and uptake represent important mechanisms of intercellular communication and exchange of a wide variety of molecules, with relevance in both physiological and pathological situations. The putative role of EVs in hemostasis and thrombosis is supported by clinical and experimental studies unraveling how these cell-derived structures affect clot formation (and resolution). From those studies, it has become clear that the prothrombotic effects of EVs are not restricted to the exposure of tissue factor (TF) and phosphatidylserines (PS), but also involve multiplication of procoagulant surfaces, cross-linking of different cellular players at the site of injury and transfer of activation signals to other cell types. Here, we summarize the existing and novel clinical and experimental evidence on the role and function of EVs during arterial and venous thrombus formation and how they may be used as biomarkers as well as therapeutic vectors.

Abstract
Hypoxic hypoxia, including abnormally low partial pressure of inhaled oxygen, external respiratory dysfunction-induced respiratory hypoxia and venous blood flow into the arterial blood, is characterized by decreased arterial oxygen partial pressure, resulting in tissue oxygen deficiency. The specific characteristics include reduced arterial oxygen partial pressure and oxygen content. Hypoxic hypoxia diseases (HHDs) have attracted increased attention due to their high morbidity and mortality and mounting evidence showing that hypoxia-induced oxidative stress, coagulation, inflammation and angiogenesis play extremely important roles in the physiological and pathological processes of HHDs-related vascular endothelial injury. Interestingly, endothelial microvesicles (EMVs), which can be induced by hypoxia, hypoxia-induced oxidative stress, coagulation and inflammation in HHDs, have emerged as key mediators of intercellular communication and cellular functions. EMVs shed from activated or apoptotic endothelial cells (ECs) reflect the degree of ECs damage, and elevated EMVs levels are present in several HHDs, including obstructive sleep apnoea syndrome and chronic obstructive pulmonary disease. Furthermore, EMVs have procoagulant, proinflammatory and angiogenic functions that affect the pathological processes of HHDs. This review summarizes the emerging roles of EMVs in the diagnosis, staging, treatment and clinical prognosis of HHDs.

Abstract
Essentials PSGL-1+ microvesicles (MVs) may be important in venous thromboembolism (VTE). We measured plasma levels and parental origin of PSGL-1+ MVs in patients with unprovoked VTE. VTE patients had higher plasma levels of PSGL-1+ MVs than healthy controls. The PSGL-1+ MVs originated mainly from monocytes and endothelial cells. SUMMARY Background Microvesicles (MVs) express antigens from their parental cells and have a highly procoagulant surface. Animal studies suggest that P-selectin glycoprotein ligand-1-positive (PSGL-1+ ) MVs play a role in the pathogenesis of venous thromboembolism (VTE). Objective The aim of this study was to determine plasma levels, the cellular origin and the morphological characteristics of PSGL-1+ MVs in patients with unprovoked VTE. Methods We conducted a population-based case-control study in 20 patients with a history of unprovoked VTE and 20 age- and sex-matched healthy controls recruited from the general population. Plasma levels, the cellular origin and the morphological characteristics of PSGL-1+ MVs were evaluated using flow cytometry, electron microscopy and confocal microscopy. Results Plasma levels of PSGL-1+ MVs were associated with increased risk of VTE. The odds ratio per one standard deviation increase in PSGL-1+ MVs was 3.11 (95% confidence interval [CI], 1.41-6.88) after adjustment for age and sex, and 2.88 (95% CI, 1.29-6.41) after further adjustment for body mass index. The PSGL-1+ MVs originated mainly from monocytes and endothelial cells determined by double staining with markers of parental cells using flow cytometry and transmission electron microscopy. Scanning electron microscopy of PSGL-1-labeled plasma-derived MVs displayed dominantly spherical vesicles that varied between 50 and 300 nm in diameter. Conclusions Increased plasma levels of PSGL-1+ MVs are associated with the risk of unprovoked VTE. Large population-based prospective studies are required to validate our findings.

Abstract
Background It is well known that fibrin network binds a large variety of proteins, including inhibitors and activators of fibrinolysis, which may affect clot properties, such as stability and susceptibility to fibrinolysis. Specific plasma clot composition differs between individuals and may change in disease states. However, the plasma clot proteome has not yet been in-depth analyzed, mainly due to technical difficulty related to the presence of a highly abundant protein—fibrinogen and fibrin that forms a plasma clot. Methods The aim of our study was to optimize quantitative proteomic analysis of fibrin clots prepared ex vivo from citrated plasma of the peripheral blood drawn from patients with prior venous thromboembolism (VTE). We used a multiple enzyme digestion filter aided sample preparation, a multienzyme digestion (MED) FASP method combined with LC–MS/MS analysis performed on a Proxeon Easy-nLC System coupled to the Q Exactive HF mass spectrometer. We also evaluated the impact of peptide fractionation with pipet-tip strong anion exchange (SAX) method on the obtained results. Results Our proteomic approach revealed 476 proteins repeatedly identified in the plasma fibrin clots from patients with VTE including extracellular vesicle-derived proteins, lipoproteins, fibrinolysis inhibitors, and proteins involved in immune responses. The MED FASP method using three different enzymes: LysC, trypsin and chymotrypsin increased the number of identified peptides and proteins and their sequence coverage as compared to a single step digestion. Peptide fractionation with a pipet-tip strong anion exchange (SAX) protocol increased the depth of proteomic analyses, but also extended the time needed for sample analysis with LC–MS/MS. Conclusions The MED FASP method combined with a label-free quantification is an excellent proteomic approach for the analysis of fibrin clots prepared ex vivo from citrated plasma of patients with prior VTE.

Abstract
SummaryMany subjects carrying inherited thrombophilic defects will never experience venous thromboembolism (VTE) while other individuals developed recurrent VTE with no known additional risk factors. High levels of circulating microparticles (MP) have been associated with increased risk of VTE in patients with factor V Leiden and prothrombin G20210A mutation, suggesting a possible contribution of MP in the hypercoagulability of mild genetic thrombophilia. The role of MP as additional risk factor of VTE in carriers of natural clotting inhibitors defects (severe thrombophilia) has never been assessed. Plasma levels of annexin V-MP, endothelial-derived MP (EMP), platelet-derived MP (PMP), tissue factor-bearing MP (TF+) and the MP procoagulant activity (PPL) were measured in 132 carriers of natural anticoagulant deficiencies (25 antithrombin, 63 protein C and 64 protein S defect) and in 132 age and gender-matched healthy controls. Carriers of natural anticoagulant deficiencies, overall and separately considered, presented with higher median levels of annexin V-MP, EMP, PMP, TF+MP and PPL activity than healthy controls (p< 0.001, < 0.001, < 0.01, 0.025 and 0.03, respectively). Symptomatic carriers with a previous episode of VTE had significantly higher median levels of annexin-V MP than those without VTE (p=0.027). Carriers with high levels of annexin V-MP, EMP and PMP had an adjusted OR for VTE of 3.36 (95 % CI, 1.59 to 7.11), 9.26 (95 % CI, 3.55 to 24.1) and 2.72 (95 %CI, 1.16 to 6.38), respectively. Elevated levels of circulating MP can play a role in carriers of mild and severe inherited thrombophilia. The clinical implications of this association remain to be defined.

Abstract
Over the past decades, there have been great advances in the understanding of the pathogenesis of venous thromboembolism (VTE) in patients with inherited and acquired thrombophilia [mainly antiphospholipid antibody syndrome (APS)]. However, a number of questions remain unanswered. Prognostic markers capable of estimating the individual VTE risk would be of great use. Microparticles (MPs) are sub-micron membrane vesicles constitutively released from the surface of cells after cellular activation and apoptosis. The effects of MPs on thrombogenesis include the exposure of phopshatidylserine and the expression of tissue factor and MPs have been described in clinical studies as possible diagnostic and prognostic biomarkers for VTE. This review will provide a novel perspective on the current knowledge and research trends on the possible role of MPs in hereditary thrombophilia and APS. Basically, the published data show that circulating MPs may contribute to the development of VTE in thrombophilic carriers, both in mild and severe states. Moreover, the presence of endothelial-MPs and platelet-MPs has been described in antiphospholipid syndrome and seems to be directly linked to antiphospholipid antibodies and not to other underlying autoimmune disorders or the thrombotic event itself. In conclusion, circulating MPs may constitute an epiphenomenon of thrombophilia itself and could be up-regulated in acute particular conditions, promoting a global prothrombotic state up to the threshold of the clinical relevant thrombotic event.

Abstract
Microparticles (MPs) are small (0.1–1.0 μm) membrane vesicles constitutively released from the surface of cells after activation and apoptosis. The clinical research on MPs is hampered by the limitations of the currently available detection methods. A correlation between MPs and venous thromboembolism (VTE) has been observed. The effects of MPs on thrombogenesis involve the exposure of phosphatidylserine, the vehiculation of tissue factor, and MP-induced intercellular cross-talk between inflammation and coagulation. This review will focus on the potential role of plasma MPs as biomarkers in detecting acute unprovoked VTE, predicting VTE occurrence in high-risk situations (mainly cancer), and ultimately, we will discuss currently available studies on the prognostic role of MPs to guide primary and secondary VTE prevention protocols.

Abstract
Prothrombin mutation was usually associated with other well-established predisposing factors for venous thrombosis such as antiphospholipid antibodies. Recently, even isolated prothrombin gene mutation G20210A has been reported to present severe or unusual vein thrombosis. Less clear is the role of prothrombin mutation in the formation of arterial thrombosis. We present a case of a 15-year-old healthy White male with acute bilateral femoral artery thrombosis. The patient presented with increasing left leg pain for about 1 week. He was a physically very active teenager with a new onset of leg pain aggravated by exercise. Physical examination revealed a pale and cold left foot with dorsal foot necrosis (2 × 2 cm) that started 2 days ago. In addition, he complained of moderate rest pain. No symptoms were noticed on the right lower extremity. The ankle brachial index was 0.3 on the left and 0.6 on the right. Duplex sonography showed bilateral superficial femoral artery thrombosis, which was confirmed by angiography. Subsequently, he undergoes left superficial femoral and popliteal artery lysis with rt-PA (Actilyse boehringer ingelheim, Ingelheim am Rhein, Germany) and full heparinization. Treatment was discontinued after 24 hours with no significant improvement of symptoms. Full anticoagulation with Coumadin (Bristol-Myers Squibb Company, New York, NY) and alprostadil (Prostavasin UCB, Brussels, Belgium) infusion for 2 weeks was initiated and eventually patient's symptoms improved. Laboratory testing revealed a homozygous prothrombin G20210A mutation and antiphospholipid syndrome. Homozygous prothrombin G20210A mutation in conjunction with antiphospholipid syndrome is a rare combination of coagulation disorder. Early intervention with full anticoagulation and subsequent lifelong anticoagulation should be considered in treatment strategy.
