Venous thromboembolism secondary prophylaxis in elderly people (over 75-year-old) with low-dose direct oral anticoagulants: single-center Italian experience.

Nowadays, direct oral anticoagulants (DOACs) represent the gold standard for venous thromboembolism (VTE) treatment and VTE secondary prophylaxis; nevertheless, the percentage of elderly patients in major trials and literature data about DOACs usage for VTE secondary prophylaxis in the elderly are scant. Our retrospective study tried to evaluate low-dose DOACs efficacy and safety for elderly VTE secondary prophylaxis in a real-life setting. A cohort of 73 patients (≥ 75 years) considered at high risk of VTE recurrence was treated with apixaban 2.

Secondary prophylaxis of venous thromboembolism (VTE) with low dose apixaban or rivaroxaban in major-thrombophilia carriers.

Direct oral anticoagulants (DOACs) are widely used for treatment and secondary prophylaxis of venous thromboembolism (VTE) and represent the gold standard for VTE secondary prophylaxis, with low-intensity DOACs administration becoming increasingly used worldwide in such scenario. Albeit widespread DOACs usage there are few literature data regarding their efficacy and safety in major thrombophilia carriers and almost no data is available for low intensity apixaban and rivaroxaban as secondary VTE prophylaxis in such patients. The aim of our study is to evaluate and confront the efficacy and safety of low-dose DOACs for VTE secondary prophylaxis, in major thrombophilia carriers vs patients at high risk of VTE recurrence for other reasons.

More early bleeds associated with high baseline direct oral anticoagulant levels in atrial fibrillation: the MAS study.

Treatment with direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF) is effective and safe. However, bleeding complications still occur. Whether DOAC level measurement may further improve treatment efficacy and safety is still an open issue.

Inappropriate Underdosing of Direct Oral Anticoagulants in Atrial Fibrillation Patients: Results from the START2-AF Registry.

Direct oral anticoagulants (DOACs) are recommended for stroke prevention in non-valvular atrial fibrillation (NVAF) patients. We aimed to describe the prevalence of inappropriate DOACs dose prescription in the START2-AF Registry, the outcomes according to the appropriateness of the dosage, and the factors associated with inappropriate dose prescription. Patients' demographics and clinical data were prospectively collected as electronic files in an anonymous form on the website of the START2-Registry; DOACs dosage was determined to be appropriate when prescribed according to the European Heart Rhythm Association Guidelines.

Long-Term Outcomes in Two-Year Follow-Up after Primary Treatment in Patients with a Prior Venous Thromboembolic Event: A Prospective, Observational, Real-Life Study.

Background: Patients with acute venous thromboembolism (VTE) need anticoagulation (AC) therapy for at least 3/6 months (primary treatment); after that period, they should receive a decision on the duration of therapy.

Methods: This study examined the complications occurring during two years of follow-up (FU) in patients with a first VTE who were recruited in 20 clinical centers and had discontinued or prolonged AC. They were included in the START2-POST-VTE prospective observational study.

Secondary Prophylaxis of Venous Thromboembolism (VTE) with Low Dose Apixaban or Rivaroxaban: Results from a Patient Population with More than 2 Years of Median Follow-up.

Background: Direct oral anticoagulants (DOACs) are widely used for the treatment and secondary prophylaxis of venous thromboembolism (VTE). Nowadays, DOACs represent the gold standard for long-term anticoagulation, with low-intensity DOACs administration becoming increasingly used worldwide in such scenario. Albeit low-intensity apixaban and rivaroxaban are approved for clinical usage as secondary VTE prophylaxis, there are few literature data regarding their efficacy and safety with a long follow-up.

Thrombotic events associated with low baseline direct oral anticoagulant levels in atrial fibrillation: the MAS study.

Although effective and safe, treatment with direct oral anticoagulants (DOAC) in atrial fibrillation (AF) is still associated with thrombotic complications. Whether the measurement of DOAC levels may improve treatment efficacy is an open issue. We carried out the observational, prospective, multicenter Measure and See (MAS) study.

Antithrombotic secondary prophylaxis with low dose of apixaban or rivaroxaban in the onco-hematologic patients: comparison with non-neoplastic patients.

Management of cancer-associated thrombosis (CAT) is usually performed employing low molecular weight heparin (LMWH) or direct oral anticoagulants (DOACs). Low-intensity DOACs are the mainstay for extended duration therapy for VTE in non-oncologic patients. The aim of our study was to evaluate the efficacy and the safety of low doses of apixaban or rivaroxaban as secondary prophylaxis in patients affected by hematological malignancies with follow-up > 12 months.

Peripherally inserted central venous catheter for pediatric acute leukemia: A retrospective 11-year single-center experience.

Background: Peripherally inserted central catheters (PICCs) are successfully increasingly used in children in onco-hematologic setting. PICC insertion, especially in oncologic patients, can be associated with adverse events (thrombosis, mechanical complications, and infections). Data regarding the use of PICC, as long-term access in pediatric patients with severe hematologic diseases, are still limited.

Low-dose apixaban or rivaroxaban as secondary prophylaxis of upper extremity deep vein thrombosis.

Upper extremity deep vein thrombosis (UEDVT) may occur without inciting factor or may be secondary to malignancy, surgery, trauma, central venous catheter or related to thoracic outlet syndrome (TOS). International guidelines recommend anticoagulant treatment for at least three months, in particular the use of vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs). No data on extended anticoagulant therapy and reduced dose of DOACs have been reported in patients affected by UEDVT with persistent thrombotic risk (active cancer, major congenital thrombophilia) or without affected vein recanalization.

SARS-CoV-2 infection predicts larger infarct volume in patients with acute ischemic stroke.

Background And Purpose: Acute ischemic stroke (AIS) is a fearful complication of Coronavirus Disease-2019 (COVID-19). Aims of this study were to compare clinical/radiological characteristics, endothelial and coagulation dysfunction between acute ischemic stroke (AIS) patients with and without COVID-19 and to investigate if and how the SARS-CoV-2 spike protein (SP) was implicated in triggering platelet activation.

Methods: We enrolled AIS patients with COVID-19 within 12 h from onset and compared them with an age- and sex-matched cohort of AIS controls without COVID-19.

Thromboembolic Complications in COVID-19 Patients Hospitalized in Italian Ordinary Wards: Data from the Multicenter Observational START-COVID Register.

 Coronavirus disease 2019 (COVID-19) infection causes acute respiratory insufficiency with severe interstitial pneumonia and extrapulmonary complications; in particular, it may predispose to thromboembolic disease. The reported incidence of thromboembolic complications varies from 5 to 30% of cases.  We conducted a multicenter, Italian, retrospective, observational study on COVID-19 patients admitted to ordinary wards, to describe the clinical characteristics of patients at admission and bleeding and thrombotic events occurring during the hospital stay.

Direct oral anticoagulants for the treatment of atrial fibrillation in patients with hematologic malignancies.

Atrial fibrillation (AF) is common in patients with cancer due to both the proinflammatory effect of neoplastic cells and to cardiotoxicity of anti-tumor therapies. Anticoagulation is still challenging in cancer patients due to increased bleeding risk related to specific neoplasms such us hematologic malignancies. The aim of this retrospective study was to evaluate the safety and the efficacy of direct oral anticoagulants (DOACs) in AF patients affected by hematologic neoplasms.

Development of Systemic Autoimmune Diseases in Healthy Subjects Persistently Positive for Antiphospholipid Antibodies: Long-Term Follow-Up Study.

We longitudinally followed a single-center cohort of anti-phospholipid (aPL) positive healthy subjects to evaluate the evolution to systemic autoimmune diseases (sAD) and to describe clinical and serological associated features. Since 2010, we have consecutively screened healthy subjects who were positive, in at least two consecutive determinations, for one or more aPL [anti-Cardiolipin (aCL) IgM/IgG, anti-Beta2Glycoprotein I (aB2GPI) IgM/IgG, Lupus Anticoagulant (LA)]. All subjects were evaluated every six months, or in accordance with the patient's clinical course, in order to record the development of clinical and laboratory features suggestive for sAD.

D-dimer and reduced-dose apixaban for extended treatment after unprovoked venous thromboembolism: the Apidulcis study.

D-dimer assay is used to stratify patients with unprovoked venous thromboembolism (VTE) for the risk of recurrence. However, this approach was never evaluated since direct oral anticoagulants are available. With this multicenter, prospective cohort study, we aimed to assess the value of an algorithm incorporating serial D-dimer testing and administration of reduced-dose apixaban (2.

Immune thrombocytopenia management during COVID-19 pandemic: An Italian monocentric experience.

Over the last 2 years, different cases of immune thrombocytopenia (ITP) in patients affected by SARS-CoV2 have been reported. The management of SARS-CoV2 in subjects with simultaneous or previous ITP can be challenging because of the great involvement of the haemostatic system in this viral infection. In this report, we describe the management and outcome of patients with newly diagnosed (ND), chronic and previous ITP, infected by COVID-19, referred to the Haematology Institute of University Hospital Policlinico Umberto I in Rome.

Secondary prophylaxis of venous thromboembolism with direct oral anticoagulants: comparison between patients with major congenital thrombophilia versus non-thrombophilic patients.

Direct oral anticoagulants (DOACs) are widely used for the treatment and secondary prophylaxis of venous thromboembolism (VTE). Congenital thrombophilia is a condition that predisposes to a higher incidence of VTE and often requires long-term anticoagulation for secondary prophylaxis. It is less clear the efficacy of DOACs in patients with major thrombophilia.
