"Blood Biomarkers Uncover Mechanistic Subtypes of Long COVID"

A large UK study of over 650 patients has identified distinct inflammation patterns in the blood of long COVID sufferers, indicating ongoing immune system activation long after initial hospitalization and correlating with different symptom types. The findings suggest potential for targeting these immune responses with existing drugs, such as IL-1 antagonists and JAK inhibitors, offering hope for new treatments. The study highlights the complexity of long COVID and the need for personalized treatment approaches, emphasizing the importance of understanding its immune mechanisms and paving the way for future clinical trials.
