Matrix metalloproteinases levels in induced sputum in IPF and CTD-ILD

Key Points

• Increased levels of matrix metalloproteinases in induced sputum are observed in patients with connective tissue disease-associated interstitial lung disease.
• The study finds significant differences in matrix metalloproteinases levels between idiopathic pulmonary fibrosis and connective tissue disease patients.
• Assessment using induced sputum analysis shows distinct profiles of matrix metalloproteinases in different interstitial lung diseases.
• Findings highlight the potential of matrix metalloproteinases as biomarkers for differentiating between types of interstitial lung disease.
