Study finds immune system breakdown causing persistent Covid

Analysis of blood samples from patients with persistent Covid-19 – a disease of unknown causes, incurable and causing, among other symptoms, persistent fatigue and cognitive decline – showed that these people are suffering changes in the protein network

and points to this is an immune failure as the most likely cause of the disease. The discovery opens the door to improving the diagnosis and treatment of persistent Covid disease, which affects approximately 5% of people infected with SARS-CoV-2.

This study was published in a prestigious journal The sciencea team from the University of Zurich (Switzerland) monitored 113 patients for more than a year, of whom 40 had persistent Covid, and compared blood test results

from both.

According to the results, patients with persistent covid had more protein who belong to complement system. This system is associated with the inflammatory and immune response.

“In patients with persistent Covid, the complement system no longer returns to its original state, but remains activated and therefore also “damages healthy cells in the body”– explained scientist Onur Boyman in a statement from the University of Zurich.

Study results identify potential biomarkers of persistent Covid-19 and open the door to new strategies care and his diagnosis.
