COVID-19 e Estado de Hipercoagulabilidade: Uma Nova Perspectiva Terapêutica
Open accessAbstract
O novo coronavírus, designado como vírus da síndrome respiratória aguda grave (SARS-CoV-2, sigla em inglês), é o responsável pelo surto da pneumonia viral que foi identificada pela primeira vez na cidade chinesa de Wuhan ao final de 2019 e que rapidamente se espalhou acometendo 184 países.A experiência adquirida nos últimos meses descreve diferentes apresentações clínicas com gravidade variável, desde infecção assintomática até óbito por disfunção orgânica múltipla.Recentemente, a Organização Mundial de Saúde (OMS) definiu o complexo processo de adoecimento por esse vírus como doença causada pelo coronavírus 2019 (COVID-19, sigla em inglês).A COVID-19, cuja notificação é crescente em diferentes países, atualmente afeta mais de um milhão de pessoas, segundo a OMS, que a caracterizou como pandemia.1 No Brasil, até o dia 29 de abril de 2020, foram confirmados 73.235 casos da infecção e 5.083 óbitos, com taxa de letalidade de 6,9%. 2 A hospitalização é necessária em até 20% dos pacientes infectados por SARS-CoV-2, e 5% a 10% deles terão indicação de internação em terapia intensiva por necessidade de suporte hemodinâmico e/ou ventilatório.[3][4][5][6][7] A taxa de mortalidade varia de 0,8% a 12% de acordo com o país, possivelmente como consequência de múltiplos fatores, dos quais se destaca a estrutura do sistema de saúde.[8][9][10][11] Os pacientes que desenvolvem as formas moderada e grave da doença apresentam manifestações predominantemente decorrentes de acometimento do sistema respiratório, com quadro clínico variando de pneumonia leve a síndrome do desconforto respiratório agudo (SDRA).

Active inflammatory cells expressing specific protease activated receptors (PAR1-4) bind to thrombin, while Toll-like receptor 4 interacts with fibrin.
“In this scenario, active inflammatory cells expressing specific protease activated receptors (PAR1–4) bind to thrombin, while the Toll-like receptor 4 interacts with fibrin.”

SARS-CoV-2-induced systemic inflammatory responses may also result in endothelial damage and consequently increased production of thrombin by inflammatory cytokines during sepsis in a bidirectional way, because inflammation activates coagulation and coagulation augments inflammatory activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
