Diagnosis and treatment of thrombotic microangiopathy.

Thrombotic microangiopathy (TMA) is characterized by thrombocytopenia, microangiopathic haemolytic anaemia and end organ damage. TMAs have varying underlying pathophysiology and can therefore present with an array of clinical presentations. Renal involvement is common as the kidney is particularly susceptible to the endothelial damage and microvascular occlusion. TMAs require rapid assessment, diagnosis, and commencement of appropriate treatment due to the high morbidity and mortality associated with them. Ground-breaking research into the pathogenesis of TMAs over the past 20 years has driven the successful development of targeted therapeutics revolutionizing patient outcomes. This review outlines the clinical presentations, pathogenesis, diagnostic tests and treatments for TMAs.

EFSA and ECDC publishes EU One Health 2020 zoonoses report

The European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC) have published the EU One Health 2020 Zoonoses Report. Campylobacteriosis was the most reported zoonosis in the EU in 2020, with 120,946 cases compared to more than 220,000 the previous year. This was followed by salmonellosis, which affected 52,702 people, compared to 88,000 in 2019. The number of reported foodborne outbreaks fell by 47%, with the report acknowledging the impact of the COVID-19 pandemic in the drop in reported zoonotic diseases in humans. The next most commonly reported diseases were yersiniosis, with 5,668 cases, and infections caused by Shiga toxin-producing Escherichia coli, with 4,446 cases. Listeriosis was the fifth most reported zoonosis, mainly affecting people over the age of 64. Listeriosis and West Nile virus (WNV) infections were the diseases with the highest case fatality and hospitalisation rates, with most locally acquired human infections of WNV reported in Greece, Spain and Italy. The report also monitors foodborne outbreaks in the EU, events during which at least two people contract the same illness from the same contaminated food. A total of 3,086 foodborne outbreaks were reported in 2020, with Salmonella remaining the most frequently detected agent, causing around 23% of outbreaks. The most common sources of salmonellosis outbreaks were eggs, egg products and pig meat. The report also includes data on Mycobacterium bovis, Mycobacterium caprae, Brucella, Trichinella, Echinococcus, Toxoplasma gondii, rabies, Q fever and tularaemia.
