The epidemiology of venous thromboembolism

Abstract: Venous thromboembolism (VTE) is categorized by the U.S. Surgeon General as a major public health problem. VTE is relatively common and associated with reduced survival and substantial health-care costs, and recurs frequently. VTE is a complex (multifactorial) disease, involving interactions between acquired or inherited predispositions to thrombosis and VTE risk factors, including increasing patient age and obesity, hospitalization for surgery or acute illness, nursing-home confinement, active cancer, trauma or fracture, immobility or leg paresis, superficial vein thrombosis, and, in women, pregnancy and puerperium, oral contraception, and hormone therapy. Although independent VTE risk factors and predictors of VTE recurrence have been identified, and effective primary and secondary prophylaxis is available, the occurrence of VTE seems to be relatively constant, or even increasing.

COVID-19 update: Covid-19-associated coagulopathy.

Abstract: The Covid-19 pandemic has introduced an array of organspecific and systemic phenotypessome previously observed in viral infections, including severe acute respiratory syndrome (SARS) and others that appear to be unique to SARScoronavirus (CoV)-2. Rapidly emerging information from clinical observations, autopsy-based findings, extrapolations from in vitro and ex vivo studies and dynamic modeling are informing management guidelines; however, many questions remain unanswered and clinical trials that are required to provide evidence have not been completed in most areas. Among the many questions that require careful thought, reflection and investigation are the mechanism(s) underlying the development of a systemic coagulopathy and acquired thrombophilia characterized in a majority of cases by a proclivity for venous, arterial and microvascular thrombosis. The following review summarizes emerging insights into the pathobiology, mechanism(s), diagnosis, management, foundations for research and either planned or ongoing clinical trials for Covid-19-associated coagulopathy.

Streptokinase and Heparin versus Heparin Alone in Massive Pulmonary Embolism: A Randomized Controlled Trial.

Abstract: To test the efficacy of thrombolytic therapy in massive pulmonary embolism, we conducted a prospective randomized controlled trial. Eight patients were randomized to receive either 1,500,000 IU of streptokinase in 1 hour through a peripheral vein followed by heparin or heparin alone. All patients had major risk factors for deep vein thrombosis (DVT) and were considered to have high clinical suspicion for pulmonary embolism (PE). At baseline all patients had a similar degree of systemic arterial hypotension, pulmonary arterial hypertension, and right ventricular dysfunction. The time of onset of cardiogenic shock in both groups was comparable (2.25 +/- 0.5 hours in the streptokinase group and 1.75 +/- 0.96 hours in the heparin group). The four patients who were randomized to streptokinase improved in the first hour after treatment, survived, and in 2 years of follow-up are without pulmonary arterial hypertension. All four patients treated with heparin alone died from 1 to 3 hours after arrival at the emergency room (p = 0.02). Post-thrombolytic therapy the diagnosis of PE was sustained in the streptokinase group by high probability V/Q lung scans and proven DVT. A necropsy study performed in three patients in the heparin group showed massive pulmonary embolism and right ventricular myocardial infarction, without significant coronary arterial obstruction. The results indicate that thrombolytic therapy reduces the mortality rate of massive acute pulmonary embolism.

Difference of coagulation features between severe pneumonia induced by SARS-CoV2 and non-SARS-CoV2.

Abstract: Severe coronavirus disease 2019 (COVID-19) is commonly complicated with coagulopathy, the difference of coagulation features between severe pneumonia induced by SARS-CoV2 and non-SARS-CoV2 has not been analyzed. Coagulation results and clinical features of consecutive patients with severe pneumonia induced by SARS-CoV2 (COVID group) and non-SARS-CoV2 (non-COVID group) in Tongji hospital were retrospectively analyzed and compared. Whether patients with elevated D-dimer could benefit from anticoagulant treatment was evaluated. There were 449 COVID patients and 104 non-COVID patients enrolled into the study. The 28-day mortality in COVID group was approximately twofold of mortality in non-COVID group (29.8% vs. 15.4%, P = 0.003), COVID group were older (65.1 ± 12.0 vs. 58.4 ± 18.0, years, P 3.0 μg/mL (32.8% vs. 52.4%, P = 0.017). Patients with severe pneumonia induced by SARS-CoV2 had higher platelet count than those induced by non-SARS-CoV2, and only the former with markedly elevated D-dimer may benefit from anticoagulant treatment.
