Elevated serum MMP3 levels as a potential biomarker of disease activity in primary Sjögren's syndrome: a prospective observational study

Puntos clave

• Elevated serum MMP3 levels correlate with increased disease activity in Sjögren's syndrome.
• A notable correlation was found, with mean serum MMP3 levels in patients being 150 ng/mL.
• This was a prospective observational study assessing biomarker relevance in disease activity.
• Further studies are needed to confirm MMP3's role as a reliable disease activity marker.
