The new coronavirus is so sophisticated that it can lead to a series of unexpected symptoms and complications that can be fatal,media BGR reported. A few weeks ago, neurologists observed that some of their patients showed symptoms consistent with neurological disorders, including confusion, seizures, and so on, while some of their patients were infected with SARS-CoV-2. Doctors at Mount Sinai Health System have previously noticed an increase in the number of young patients with stroke symptoms. All of them tested positive for COVID-19, suggesting that the virus may be the cause of blood clots that can reach the brain and then clog local arteries.
It turns out that the disease does cause blood clotting to increase, with tiny blood clots forming in the lungs. Now, researchers are finally figuring out how it all happened. Doctors from the Irish Vascular Biology Centre (RCSI) and St James’s Hospital in Dublin published a study in the British Journal of Haematology saying abnormal blood clotting was one of the causes of death in patients with COVID-19. After infection, microclots form inside the lungs, and the higher the amount of clotting, the worse the prognosis.
“Our new findings suggest that COVID-19 is associated with a unique blood clotting disorder, which is concentrated in the lungs, which is undoubtedly the cause of the high mortality rate in patients with COVID-19,” said Professor James O’Donnell, Director of the Irish Centre for Vascular Biology.
The team referred to the disease as pulmonary intravascular coagulation (PIC), which is different from the diffuse intravascular coagulation disease (DIC) observed in other conditions. The disease may be the cause of blood clots entering the brain or heart, where they can lead to a stroke or heart attack. It can also explain oxygenation problems that occur in severe COVID-19 cases, leading to the need for oxygen therapy and ventilation.
“In addition to pneumonia, which affects small air bags in the lungs, we also found hundreds of small blood clots throughout the lungs. This condition is not visible in other types of lung infections, which explains why blood oxygen levels in severe COVID-19 infections drop sharply,” the doctor said. “Further research is needed to see whether different blood thinning therapies are useful for selected high-risk patients to reduce the risk of thrombosis.” “
The team also found that patients with high thrombosis were more likely to need intensive care. The new study also suggests that race and ethnicity may have a significant impact on blood clot risk, with Caucasian and African-American patients more likely than Chinese patients to have COVID-19-related thrombosis. White sons are three to four times more likely to develop this complication than those in China, the study said. African-American patients were significantly at higher risk, the paper said.
