Abstract

Background: In cystic fibrosis (CF), cross-sectional studies have reported sputum matrix metalloproteinase (MMP)-9 to be elevated and negatively
correlated with FEV1. This longitudinal study examined the association between MMP-9 and tissue inhibitors of metalloproteinases (TIMPs) to
prognostic parameters in CF.
Method: A cross-sectional survey of CF and control subjects; CF patients were followed up for a median of 49 months. MMP-9 and TIMP-1 and
TIMP-2 were quantified in sputum and plasma.
Results: Seventy-three patients with CF, median age 22 years, and 40 controls were recruited. Fifty-three of these CF patients were followed up.
Prospectively, in CF subjects, plasma MMP-9 activity was adversely associated with FEV1 (β −1.15 (95% CI −2.10, −0.20), p = 0.019) and rate
of FEV1 decline, and plasma TIMP-1 was adversely associated with mortality: hazard ratio 3.66 (1.91–7.04), p b 0.001.
Conclusions: These associations further justify investigation of MMP-9 and TIMP-1 as biomarkers for short- to medium-term FEV1 decline and
mortality in patients with CF.
