Fahal, Peter McClelland, Charles R.M. Hay' and Gordon M. Bell The Regional Renal Unit and 'Department ofHaematology, Royal Liverpool University Hospital, Prescot Street, Liverpool L7 8XP, UK Summary: Thrombosis is a frequent cause of morbidity and mortality in patients with the nephrotic syndrome. Venous thrombotic complications are well recognized but arterial complications are rare. Thrombosis is multifactorial, and has been attributed to a hypercoaguable state due to alterations in blood levels of the various factors involved in the coagulation and fibrinolytic systems, alterations in platelet function, venous stasis, haemoconcentration, increased blood viscosity and possibly the administration of steroids. Thrombosis in general and arterial thrombosis in particular is a significant and potentially serious problem in nephrotic patients. Awareness of the condition and its pathogenesis is needed. Assessment for the risk factors is required to allow appropriate prophylactic measures to be taken. Introduction Thrombotic complications are common in the 135% (75-125), fibrinogen 13.1 g/l (1.5-4 g/l) and nephrotic syndrome.

Conflicts of Interests: The authors declare there are no competing interests. This article is licensed under a Commons Attribution Non-Commercial 4.0 License ABSTRACT The Medicines and Healthcare products Regulatory Agency (MHRA) of the UK has approved the use of three vaccines to combat COVID-19 (SARS-CoV-2). There have been rare reports of thrombosis after vaccination with the AstraZeneca vaccine. We present three cases of vaccine-induced thrombotic thrombocytopenia (VITT) in one UK district general hospital following administration of this vaccine. Two of the patients had asymptomatic pulmonary emboli, while the other is the first known case of both renal vein thrombosis and pulmonary embolism. LEARNING POINTS • Vaccine-induced thrombotic thrombocytopenia (VITT) can be associated with unusual and multiple sites of thrombosis. • Clinicians should have a low threshold for requesting anti-PF4 antibody tests and imaging (especially pulmonary imaging) in thrombocytopenic patients after administration of the AstraZeneca vaccine. • We describe a localised cluster of VITT despite its rarity according to current statistics, highlighting the need for an efficient data collection system to ensure the incidence of VITT is accurately reported.
