Sammendrag
Background. Age-related reduction of glomerular filtration rate (GFR) is a major contributor to the global chronic kidney disease (CKD) epidemic. We investigated whether baseline serum levels of the pro-fibrotic matrix metalloproteinase 2 (MMP2), MMP7 and their inhibitor, tissue inhibitor of metalloproteinase 1 (TIMP1), which mediates fibrosis development in aging animals, were associated with GFR decline in a general non-diabetic population.

Methods. In the Renal Iohexol Clearance Survey, we measured GFR using iohexol clearance in 1627 subjects aged 50–64 years without self-reported diabetes, kidney or cardiovascular disease.After a median of 5.6 years, 1324 had follow-up GFR measurements. Using linear mixed models and logistic regression analyses, we evaluated the association of MMP7, MMP2 and TIMP1 with the mean GFR decline rate, risk of accelerated GFR decline (defined as subjects with the 10% steepest GFR slopes: 1.8 mL/min/1.73 m2 /year) and incident CKD [GFR<60 mL/ min/1.73 m2 and/or urinary albumin to creatinine ratio (ACR) 3.0 mg/mmol].

Results. Higher MMP7 levels (per standard deviation increase of MMP7) were associated with steeper GFR decline rates [0.23 mL/min/1.73 m2 /year (9<5% confidence interval 0.34 to 0.12)] and increased risk of accelerated GFR decline and incident CKD [odds ratios 1.58 (1.30–1.93) and 1.45 (1.05–2.01), respectively, in a model adjusted for age, sex, baseline GFR, ACR and cardiovascular risk factors]. MMP2 and TIMP1 showed no association with GFR decline or incident CKD. Conclusions. The pro-fibrotic biomarker MMP7, but not MMP2 or TIMP1, is associated with increased risk of accelerated GFR decline and incident CKD in middle-aged persons from the general population.
