London: Scientists in Ireland have identified how and why some COVID-19 patients can develop life-threatening clots, which could lead to targeted therapies that prevent this from happening. The study, led by researchers from Royal College of Surgeons in Ireland (RCSI) University of Medicine and Health Sciences and published in the ‘Journal of Thrombosis and Haemostasis’, found that the balance between a molecule that causes clotting, called von Willebrand Factor (VWF), and its regulator called ADAMTS13, is severely disrupted in patients with severe COVID-19. Previous research has established that blood clotting is a significant cause of death in patients with COVID-19.

“Our research helps provide insights into the mechanisms that cause severe blood clots in patients with COVID-19, which is critical to developing more effective treatments,” said Dr Jamie O’Sullivan, the study’s corresponding author and research lecturer within the Irish Centre for Vascular Biology at RCSI.
While more research is needed to determine whether targets aimed at correcting the levels of ADAMTS13 and VWF may be a successful therapeutic intervention, it is important that we continue to develop therapies for patients with COVID-19. COVID-19 vaccines will continue to be unavailable to many people throughout the world, and it is important that we provide effective treatments to them and to those with breakthrough infections, he said.
To understand why that clotting happens, the researchers analysed blood samples that were taken from patients with COVID-19 in the Beaumont Hospital Intensive Care Unit in Dublin. When compared to control groups, the blood of COVID-19 patients had higher levels of the pro-clotting VWF molecules and lower levels of the anti-clotting ADAMTS13.
Furthermore, the researchers identified other changes in proteins that caused the reduction of ADAMTS13. The study was funded by Irish COVID-19 Vasculopathy Study (ICVS) through the Health Research Board COVID-19 Rapid Response award as well as a philanthropic grant from the 3M Foundation to RCSI University of Medicine and Health Sciences in support of COVID-19 research.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene.
