A recent discovery made by researchers at Imperial College London could mark a significant step forward in treating long Covid, thanks to findings which show noticeable traces of ongoing inflammation in the blood of patients with persistent symptoms. Published in Nature Immunology, the research analyzed blood samples from over 650 hospitalised cases and identified that long Covid may be characterized by immune system activation. This breakthrough suggests that drugs aimed at modulating the immune response could potentially help treat the condition, which is estimated to affect around 65 million people globally.

The study’s scope includes findings that inflammation caused by myeloid cells and complement system proteins could be crucial in understanding and managing long Covid. Led by Professor Peter Openshaw and Dr. Felicity Liew, the research team highlighted the necessity for further exploration into the condition, with particular attention on the inflammation’s role in causing persistent long Covid symptoms such as fatigue and brain fog.

Funded by UK Research and Innovation and the National Institute for Health and Care Research, the research was a collaborative effort across several UK universities. It points towards a more nuanced understanding of long Covid, emphasizing the potential for existing anti-inflammatory drugs to target the condition effectively.

Notably, the study offers a glimpse into the mechanisms driving long Covid, revealing that specific blood proteins linked to inflammation could be directly related to the diverse symptoms experienced by patients. This finding not only paves the way for more personalized treatment options by categorizing patients into sub-groups based on their symptoms but also provides hope for future clinical trials focused on utilizing anti-inflammatory drugs to mitigate the condition.

This research aligns with the growing need for a deeper understanding of long Covid, aiming to improve care and treatment for those affected by its long-lasting impacts.
