Inflammation markers in saliva of Long COVID patients linked to body weight and illness severity

This study evaluated oral inflammatory biomarkers in patients with Long COVID, focusing on matrix metalloproteinase (MMP) -8 and -9.

• Long COVID is associated with ongoing systemic symptoms that may involve oral inflammation.
• Matrix metalloproteinases (MMP) -8 and -9, which are linked to inflammation, were specifically analyzed in this context.
• The oral rinse samples were used to assess the levels of these inflammatory biomarkers in Long COVID patients.
• The inflammatory profile in the oral environment of Long COVID patients remains unclear and warrants further investigation.
