U.S. physicians found many micro clots in capillaries of patients who died with coronavirus

In the capillaries of patients who died with coronavirus, American doctors found many micro clots, which resulted in insufficient oxygenation of the brain, reported in the scientific journal JAMA Neurology.

It is noted that these were five elderly patients who suffered from impaired consciousness, loss of consciousness, and other negative effects of COVID-19 on the brain. “Their capillaries showed signs of chronic oxygen deficiency and many megakaryocytes – cells that are responsible for producing ‘building materials’ for blood clots,” the article says.

Scientists have not yet been able to answer where these cells come from in the blood vessels. According to the researchers, the penetration of megakaryocytes into the capillaries of the brain is linked specifically to the coronavirus.

Associate Professor of Johns Hopkins University (USA), David Nauen, and his colleagues believe that the infection affects the work of the cells in the blood vessels, due to which they begin production of signaling substances that provoke the formation of blood clots. To confirm this hypothesis, scientists will analyze new samples of vascular and brain tissue.

Earlier it was reported that researchers found a link between incurable Alzheimer’s disease and the severe course of COVID-19. It turned out that the ApoE4 gene, which increases the risk of bluetongue dementia, also increases a person’s susceptibility to the coronavirus.
