Insights
COVID-19 is linked to a unique coagulopathy, increasing venous thromboembolism (VTE) risk. This review examines VTE incidence, guideline discrepancies, and ongoing trials for anticoagulation strategies in COVID-19 patients.
Area of Science:
- * Internal Medicine
- * Hematology
- * Critical Care Medicine
Background:
- * The novel coronavirus disease 2019 (COVID-19) presents a significant risk of venous thromboembolism (VTE).
- * COVID-19 is associated with a distinct coagulopathy requiring careful management.
- * Guidance from major societies on managing this coagulopathy has emerged.
Purpose of the Study:
- * To provide an updated focus on thromboprophylaxis in COVID-19 patients.
- * To compare current VTE incidence in intensive care unit (ICU) and non-ICU patients.
- * To highlight discrepancies between International Society on Thrombosis and Haemostasis (ISTH) and American College of Chest Physicians (CHEST) guidelines and discuss ongoing trials.
Main Methods:
- * Review of recent published studies on VTE incidence in COVID-19 patients.
- * Analysis of current guidelines from ISTH and CHEST regarding thromboprophylaxis.
- * Summary of key ongoing randomized controlled trials (RCTs) investigating anticoagulation strategies.
Main Results:
- * Significant VTE incidence reported in both ICU and non-ICU COVID-19 patients.
- * Identified discrepancies in thromboprophylaxis recommendations between ISTH and CHEST guidelines.
- * Several RCTs are underway to evaluate optimal anticoagulation in COVID-19.
Conclusions:
- * COVID-19 coagulopathy necessitates specific attention to VTE risk and management.
- * Further research and clarification of guidelines are crucial for effective thromboprophylaxis.
- * Ongoing trials are expected to refine anticoagulation strategies for COVID-19 patients.
Abstract:
A common and potent consideration has recently entered the landscape of the novel coronavirus disease of 2019 (COVID-19): venous thromboembolism (VTE). COVID-19 has been associated to a distinctive related coagulopathy that shows unique characteristics. The research community has risen to the challenges posed by this « evolving COVID-19 coagulopathy » and has made unprecedented efforts to promptly address its distinct characteristics. In such difficult time, both national and international societies of thrombosis and hemostasis released prompt and timely responses to guide recognition and management of COVID-19-related coagulopathy. However, latest guidelines released by the international Society on Thrombosis and Haemostasis (ISTH) on May 27, 2020, followed the American College of Chest Physicians (CHEST) on June 2, 2020 showed some discrepancies regarding thromboprophylaxis use. In this forum article, we would like to offer an updated focus on thromboprophylaxis with current incidence of VTE in ICU and non-ICU patients according to recent published studies; highlight the main differences regarding ISTH and CHEST guidelines; summarize and describe which are the key ongoing RCTs testing different anticoagulation strategies in patients with COVID-19; and finally set a proposal for COVID-19 coagulopathy specific risk factors and dedicated trials.
