The prospective association of albuminuria, a marker of endothelial dysfunction, with interstitial lung abnormalities (ILA) and high-attenuation areas (HAA) remains unexplored.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The study included participants with available spot urinary albumin-creatinine ratio (UACR) and CT data for ILA and HAA enrolled in two independent cohorts, MESA (Multi-Ethnic Study of Atherosclerosis; n=2\u2009248) and AGES-Reykjavik (Age, Gene\/Environment Susceptibility-Reykjavik; n=3509). HAA were defined as the percentage of imaged lungs with attenuation between \u2212600 and \u2212250 Hounsfield units (MESA only). Regression modeling was performed to assess the associations of UACR with ILA and HAA, adjusted for anthropometric and demographic variables and kidney function. Cox proportional-hazard models were used to examine whether ILA modified the association between albuminuria and all-cause mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Log-transformed UACR was significantly associated with ILA, with an odds ratio (OR) of 1.21 (95% CI, 1.12\u20131.30) in MESA and OR 1.13 (95% CI, 1.06\u20131.21) in AGES-Reykjavik. In multivariable-adjusted models incorporating age, albuminuria was no longer associated with ILA, nor with ILA progression in AGES-Reykjavik. In MESA, higher levels of albuminuria were associated with greater HAA (mean increase of 1.02% per 1-unit increment in log-transformed UACR, 95% CI, 1.01\u20131.02%), even after adjusting for covariates including age.
