Covid-19 Infection: Even today the world has not completely recovered from the Covid pandemic. Now a big revelation has come regarding this. In fact, scientists have found small clots and immune system-related changes in the blood of long Covid patients, which can cause this long-term condition and can also open the way for future treatment. This is because most people recover completely from Covid-19 infection after a few days of cold, sore throat, cough or fever. But there are many patients who suffer from problems like fatigue, brain fog, body ache and breathlessness for a long time. This is called Long Covid. The reason behind these symptoms was not yet clear. Let us tell you what the scientists have found regarding this.

What came out in the research?

Now scientists have identified two important changes in long Covid patients, microclots present in the blood and changes in the immune cells neutrophils. Microclots are unusual clusters of clotting proteins circulating in the blood, which were first seen in samples from Covid patients.

Research also found that in long Covid patients, white blood cells called neutrophils undergo a special change. This change helps them to expel their DNA and move them forward to form thread-like structures. These are called neutrophil extracellular traps, which help detect and destroy infection.

What do experts say?

Scientists believe that in some Covid patients, this interaction between microclots and NETs starts a series of reactions in the body, which can ultimately lead to Long Covid. Microclots are thought to encourage NETs to form excessively, which increases inflammation and blood clot-related problems and prolongs Covid-like symptoms.

In structural examination of plasma of long Covid patients, the amount of microclots and NETs was found to be much higher than that of healthy people. The study also revealed that the patients’ microclots were larger in size.

According to study author Alain Thierry, “This discovery suggests that some physical processes are going on between microclots and NETs, ​​which can go out of control and cause disease.”

Researcher Risia Pretorius said that this interaction could protect microclots from the body’s natural clot breaking process, causing them to remain in the blood for a long time and cause problems related to blood vessels.

In a study published in the Journal of Medical Virology, scientists said that excessive formation of NETs makes microclots more stable, which may contribute to the symptoms of Long Covid. The research team says that this discovery is going to provide an opportunity to understand Long Covid.
