Post-Covid research: The quest for a common origin

Could persistent inflammation in the brain be a common cause behind the symptoms experienced by many post-Covid patients? Under the coordination of Maastricht University, scientists from across the Netherlands are joining forces to uncover the underlying causes of symptoms such as fatigue, post-exertional malaise, and concentration issues.

Inflammation

Why do people with post-Covid experience symptoms that seem to suggest a neurological origin? There is some evidence indicating brain involvement; researchers have observed inflammatory processes in both brain tissue and blood. Therefore, an interdisciplinary team of researchers from Maastricht University, Utrecht UMC, Radboud UMC, Erasmus MC, and Amsterdam UMC is given the chance to further investigate the matter. They received a grant of nearly 800 thousand euros from ZonMw, and can now further study the role of persistent brain inflammation and disruption of the brain’s control over immune, autonomic, and hormonal functions.

“Our approach is designed to integrate extensive biological measurements on different levels, spanning from molecular profiling of the blood to brain imaging, within the same individual. Thereby, we pursue a comprehensive understanding of the interconnected biological systems affected by post-Covid,” explains project leader Martina Summer-Kutmon from the Maastricht Centre for Systems Biology.

The team is building their research on existing data from three ongoing clinical studies and will do extensive follow-up measurements in a subgroup of patients. “Colleagues in university hospitals in Amsterdam and Utrecht are performing advanced brain scans, while the team at Radboud University Medical Centre will examine the immune system, and the Erasmus Medical Centre will investigate immune cells and viral persistence. Here in Maastricht, we are bringing all the data together in a post-Covid disease map,” says Summer-Kutmon.

This research, titled “The quest for a common origin: how neuroinflammation in post-Covid dysregulates brain function,” was developed in close consultation with patient representatives who will be involved in the research process. Through the collaboration with the Post-Covid Network Nederland (PCNN), the team will connect with a broader community of patients, researchers, and clinicians to enhance the insights and impact of the study.

The whole team is eager to start our work on this project to better understand and address the challenges faced by many post-Covid patients.
