ABSTRACT
Coagulopathy and thrombosis associated with coronavirus disease 2019 (COVID-19) represent a major issue in the management of this disease. In the past months, clinical studies have demonstrated that COVID-19 patients present with a particular hypercoagulable state, in which a markedly increased D-dimer concomitant with increased levels of fibrinogen are observed. This hypercoagulable state leads to an increased risk of thrombosis, which seems to be higher among those patients with critical symptoms of COVID-19. The best therapeutic approach to prevent thrombotic events in COVID-19 has not been determined yet and several questions regarding thromboprophylaxis therapy, such as the time to initiate anticoagulation, type of anticoagulant and dose regimen, have emerged among physicians. To address these concerns, several medical societies have published position papers to provide the opinion of thrombosis experts on the management of coagulopathy and thrombosis associated with COVID-19. In line with this, the Latin America Cooperative Group of Hemostasis and Thrombosis (Grupo CLAHT) has constituted a panel of experts in thrombosis and hemostasis to discuss the available data on this topic. The aim of this review is to summarize the current evidence regarding hemostatic impairment and thrombotic risk in COVID-19 and to provide a carefully revised opinion of Latin American experts on the thromboprophylaxis and management of thrombotic events and coagulopathy in patients with suspected COVID-19.
La coagulopatía y la trombosis asociadas a la enfermedad por coronavirus 2019 (COVID-19) representan un problema importante en el manejo de esta enfermedad. Los estudios clínicos de los últimos meses han demostrado que los pacientes con COVID-19 presentan un estado de hipercoagulabilidad particular, en el que se observa un aumento notable del dímero D concomitante con niveles elevados de fibrinógeno. El estado de hipercoagulabilidad conduce a un mayor riesgo de trombosis, que parece ser mayor entre aquellos pacientes con síntomas críticos de COVID-19. El mejor enfoque terapéutico para prevenir los eventos trombóticos en esta nueva enfermedad aún no se ha determinado y han surgido varias preguntas con respecto a la tromboprofilaxia, como el momento adecuado para iniciar la anticoagulación, el tipo de anticoagulante y el régimen de dosis. Para abordar estas preocupaciones, varias sociedades médicas han publicado artículos de posición para brindar la opinión de expertos en trombosis sobre el manejo de la coagulopatía y trombosis asociadas a COVID-19. Grupo Cooperativo Latinoamericano de Hemostasia y Trombosis (Grupo CLAHT) ha convocado a un panel de expertos en trombosis y hemostasia para discutir los datos disponibles sobre este tema. El objetivo de esta revisión es resumir la evidencia actual con respecto al deterioro hemostático y el riesgo trombótico en el COVID-19 y proporcionar una opinión cuidadosamente revisada de los expertos latinoamericanos sobre la tromboprofilaxis y el manejo de eventos trombóticos y coagulopatía en pacientes con sospecha de COVID-19.

Pulmonary embolism response teams (PERTs) have emerged as a multidisciplinary, multispecialty team of experts in the care of highly complex symptomatic acute pulmonary embolism (PE), with a centralized unique activation process, providing rapid multimodality assessment and risk stratification, formulating the best individualized diagnostic and therapeutic approach, streamlining the care in challenging clinical case scenarios (e.g., intermediate-high risk and high-risk PE), and facilitating the implementation of the recommended therapeutic strategies on time. PERTs are currently changing how complex acute PE cases are approached. The structure, organization, and function of a given PERT may vary from hospital to hospital, depending on local expertise, specific resources, and infrastructure for a given academic hospital center. Current emerging data demonstrate the value of PERTs in improving time to PE diagnosis; shorter time to initiation of anticoagulation reducing hospital length of stay; increasing use of advanced therapies without an increase in bleeding; and in some reports, decreasing mortality. Importantly, PERTs are positively impacting outcomes by changing the paradigm of care for acute PE through global adoption by the health-care community.

Novel coronavirus 2019 (COVID-19) represents a significant risk factor for the development of venous thromboembolism (VTE) in hospitalized with both moderate and severe/critical COVID-19. Herein, we present a brief updated review on emerging robust data on diverse thromboprophylaxis strategies used to mitigate VTE complications, as well as a personal point of view of current controversies in regards the use of therapeutic and prophylactic anticoagulation strategies, particularly in the moderately-ill subgroup of patients with COVID-19.

The risk of venous thromboembolism (VTE) in COVID-19 patients is a growing problem. Thromboembolic complications are associated with the infection by SARSCoV-2, with an estimated incidence up to 25%-30% of VTE in patients with severe COVID-19 pneumonia. Here in, we present a case of a patient with severe pneumonia due to COVID-19 who is admitted with mild pneumothorax secondary to COVID-19 and high-intermediate-risk pulmonary embolism (PE), who underwent successfully a highflow nasal cannula (HFNC) oxygenation bridge with subsequent successful half-doses of systemic thrombolysis with intravenous alteplase. Prospective studies are warranted in this subset of patients with intermediate-high and high-risk PE, to further explore HFNC oxygenation with or without diverse reperfusion strategies, with the aim to identify the best individualized therapeutic approach in each patient with significant COVID-19 associated VTE and optimize outcomes.

Venous thromboembolism associated with COVID-19, particularly acute pulmonary embolism, may represent a challenging and complex clinical scenario. The benefits of having a multidisciplinary pulmonary embolism response team (PERT) can be important during such a pandemic. The aim of PERT in the care of such patients is to provide fast, appropriate, multidisciplinary, team-based approach, with the common goal to tailor the best therapeutic decision making, prioritizing always optimal patient care, especially given lack of evidence-based clinical practice guidelines in the setting of COVID-19, which potentially confers a significant prothrombotic state. Herein, we would like to briefly emphasize the importance and potential critical role of PERT in the care of patients in which these two devastating illnesses are present together.

The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus (SARS- CoV-2) is our latest pandemic and has turned out to be a global public health crisis. One of the special characteristics of this disease is that it may predispose patients to thrombotic disease both in the venous and arterial circulation. We review arterial and venous thromboembolic complications in patients with COVID-19, epidemiology, pathogenesis, hematologic biomarkers, and current antithrombotic strategies. Future perspectives and clinical trials are ongoing to determine the best thromboprophylaxis strategies in the hospitalized patients with severe COVID-19.

La enfermedad grave por coronavirus 2019 (COVID-19) está causada por el Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) y predispone a complicaciones trombóticas. En esta revisión se aborda de manera práctica la estrecha relación entre la tromboembolia venosa y la COVID-19, enfatizando aspectos epidemiológicos, factores de riesgo y tromboprofilaxis, así como potenciales opciones de anticoagulación. Actualmente la evidencia científica es muy escasa, pero día a día seguimos aprendiendo, estando atentos a cambios novedosos y dinámicos en esta enfermedad infecciosa e inmunotrombótica emergente.
ABSTRACT
The disease caused by a new coronavirus, which started in 2019, was named COVID-19 and declared a pandemic on March 11, 2020 by the World Health Organization. Although it is true that the first reports emphasized the respiratory manifestations of this disease as an initial clinical presentation, little by little cases with different initial manifestations began to appear, involving other systems. In cases where central nervous system involvement was identified, the most frequent findings were dizziness, headache, and alteration of alertness. Regarding the cardiovascular system, elevation of cardiac biomarkers and myocarditis are one of the most frequent findings. The main gastrointestinal symptoms described so far are: anorexia, nausea, vomiting, diarrhea, abdominal pain and/or discomfort. Venous thromboembolism is a frequent complication and a public health problem. Skin manifestations remain a field of investigation. Maculopapular rashes, reticular livedo, acral gangrene, among others, have been identified. Health personnel must be updated on new clinical findings and the forms of presentation of this partially known disease, which will make it possible to make more accurate and timely diagnoses, thus impacting the prognosis of these patients.
La enfermedad causada por un nuevo coronavirus, que inició en 2019, fue denominada COVID-19 y declarada pandemia el 11 de marzo de 2020 por la Organización Mundial de la Salud. Si bien es cierto que los primeros reportes enfatizaron las manifestaciones respiratorias de esta enfermedad como presentación clínica inicial, poco a poco empezaron a aparecer casos con manifestaciones iniciales distintas, involucrando otros sistemas. En los casos en los que se identificó afectación del sistema nervioso central, los hallazgos más frecuentes fueron mareo, cefalea y alteración del estado de alerta. Respecto al sistema cardiovascular, la elevación de biomarcadores cardiacos y la miocarditis son unos de los hallazgos más frecuentes. Los principales síntomas gastrointestinales descritos hasta el momento son anorexia, náuseas, vómitos, diarrea y dolor o disconfort abdominal. La tromboembolia venosa es una complicación frecuente y un problema de salud pública. Las manifestaciones cutáneas siguen siendo un campo de investigación. Se han identificado exantemas maculopapulares, livedo reticular y gangrena acral, entre otros. El personal sanitario debe estar actualizado sobre los nuevos hallazgos clínicos y las formas de presentación de esta enfermedad solo parcialmente conocida, lo que permitirá hacer diagnósticos más precisos y oportunos, y así impactar en el pronóstico de estos enfermos.
