COVID-19, microangiopathy, hemostatic activation, and complement

Complement activation in thrombotic microangiopathy.

The endothelium lining the vascular lumen is continuously exposed to complement from the circulation. When erroneously activated on host cells, complement may generate a deleterious effect on the vascular wall leading to endothelial injury, exposure of the subendothelial matrix and platelet activation. In this review the contribution of complement activation to formation and maintenance of the ...

Complement, thrombotic microangiopathy and disseminated intravascular coagulation

In the blurring boundaries between clinical practice and scientific observations, it is increasingly attractive to propose shared disease mechanisms that could explain clinical experience. With the advent of available therapeutic options for complement inhibition, there is a push for more widespread application in patients, despite a lack of clinically relevant research. Patients with dissemina...

Murine Thrombotic Microangiopathy ADAMTS13 Deficiency in Human and Complement Activation Associated with

COVID-19 and dermatologists

Since the beginning of COVID-19 pandemic on December 2019, challenges on economic, political, social, hygiene- therapeutic and life style have emerged in many countries. Many researches are investigating on virus characteristics and its behavior and also preventive and therapeutic measures. Despite the virus not being dermatotropic, several skin manifestations have been observed. In this review...

Therapeutic Complement Targeting in ANCA-Associated Vasculitides and Thrombotic Microangiopathy

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) are a group of systemic autoimmune disorders characterized by necrotizing inflammation of medium-tosmall vessels, a relative paucity of immune deposits, and an association with detectable circulating ANCAs. AAVs include granulomatosis with polyangiitis (renamed from Wegener’s granulomatosis), microscopic polyangiitis, an...
