Contribution of the von Willebrand factor/ADAMTS13 imbalance to COVID-19 coagulopathy

American Journal of Physiology. Heart and Circulatory Physiology, 2021
The 2019 coronavirus disease (COVID-19) is the disease caused by SARS-CoV-2 infection. Although this infection has been shown to affect the respiratory system, a high incidence of thrombotic events has been observed in severe cases of COVID-19 and in a ...

A conformation-sensitive monoclonal antibody against the A2 domain of von Willebrand factor reduces its proteolysis by ADAMTS13. [PDF]

PLoS ONE, 2011
The size of von Willebrand factor (VWF), controlled by ADAMTS13-dependent proteolysis, is associated with its hemostatic activity. Many factors regulate ADAMTS13-dependent VWF proteolysis through their interaction with VWF.

Burden of acquired thrombotic thrombocytopenic purpura: KSA and UAE expert consensus for improved disease management

Journal of Applied Hematology, 2022
BACKGROUND: In Saudi Arabia (KSA) and the United Arab Emirates (UAE), only limited epidemiological data and treatment guidance exist for acquired thrombotic thrombocytopenic purpura (aTTP), a rare, life-threatening blood disorder.

ADAMTS13 activity to von Willebrand factor antigen ratio predicts acute kidney injury in patients with COVID‐19: Evidence of SARS‐CoV‐2 induced secondary thrombotic microangiopathy

International Journal of Laboratory Hematology, 2020
Severe COVID‐19 is often compounded by a prothrombotic state that is associated with poor outcomes. In this investigation, we aimed to evaluate ADAMTS13 activity, von Willebrand factor level (VWF:Ag), and the corresponding ADAMTS13 activity/VWF:Ag ratio,

Anti-ADAMTS13 Antibodies and a Novel Heterozygous p.R1177Q Mutation in a Case of Pregnancy-Onset Immune-Mediated Thrombotic Thrombocytopenic Purpura

TH Open, 2018
In this study, we investigated a case of pregnancy-onset thrombotic thrombocytopenic purpura (TTP). The patient had severely decreased ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 motif, member 13) activity levels during acute ...

Diagnosis and follow‐up of thrombotic thrombocytopenic purpura with an automated chemiluminescent ADAMTS13 activity immunoassay

Research and Practice in Thrombosis and Haemostasis, 2021
Background Thrombotic thrombocytopenic purpura (TTP) is a life‐threatening thrombotic microangiopathy (TMA) caused by a severe functional deficiency in ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type I repeats‐13), the specific von ...

Plasma and rhADAMTS13 reduce trauma-induced organ failure by restoring the ADAMTS13-VWF axis.

Blood Advances, 2021
Trauma-induced organ failure is characterized by endothelial dysfunction. The aim of this study was to investigate the role of von Willebrand factor (VWF) and its cleaving enzyme, ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 ...

Use of PopPK and E‐R Analyses toward Explaining Causal Link Between ADAMTS13 in Recombinant vs. Plasma‐Based Therapies and Clinical Effects in cTTP

Clinical Pharmacology &Therapeutics, EarlyView.
Congenital thrombotic thrombocytopenic purpura (cTTP) is an ultra‐rare, potentially life‐threatening condition caused by a deficiency of the blood enzyme ADAMTS13. Until now, ADAMTS13 replacement has been achieved with infusions of plasma or plasma‐based therapies (PBT).

Glycans of plasma ADAMTS13 [PDF]

Blood, 2016
In this issue of Blood , [Verbij et al][1] identified the sites of glycosylation in plasma ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) and determined the composition of the glycan structures at these sites.[1][2] ADAMTS13 is a blood enzyme ...
