It is unknown whether this is due to a generalized humoral prothrombotic state or endothelial factors such as inflammation and dysfunction. The aim was to further characterize thrombin generation using a novel analyser (ST Genesia, Diagnostica Stago, Asnières, France) and a panel of haematological analytes in patients with COVID-19. Platelet poor plasma of 34 patients with noncritical COVID-19 was compared with 75 patients with critical COVID-19 (as defined by WHO criteria) in a retrospective study by calibrated automated thrombography and ELISA. Patients were matched for baseline characteristics of age and gender. Critical patients had significantly increased fibrinogen, CRP, interleukin-6 and D-dimer compared to noncritical patients. Thrombin generation, in critical patients, was right shifted without significant differences in peak, velocity index or endogenous thrombin potential. Tissue plasminogen activator (tPA), tissuomplexes and prothrombin fragment 1 + 2) when comparing both cohorts; counter-intuitively critical patients were hypocoaguable. tPA, TFPI and VEGF were increased in critical patients, which are hypothesized to reflect endothelial dysfunction and/or contribution of heparin (which may cause endothelial TFPI/tPA release).We read with great interest the recently published 2020 American College of Rheumatology guideline for the management of gout. Switching to an alternative oral urate-lowering therapy (ULT) agent is conditionally recommended for patients taking febuxostat with a history of cardiovascular disease (CVD) or a new CVD-related event. The limitation of underlying evidence based on FDA-mandated CARES trial was addressed, i.e. a high dropout rate with a majority of deaths occurring after ULT discontinuation. Deficiency of adenosine deaminase 2 (DADA2) is a potentially fatal monogenic syndrome characterized by vari
