BACKGROUND: The primary biomarkers used to define CKD are serum creatinine and
albuminuria. These biomarkers have directed focus on the filtration and barrier
functions of the kidney glomerulus even though albuminuria results from tubule
dysfunction as well. Given that proximal tubules make up ?90% of kidney cortical
mass, we evaluated whether a sensitive and specific marker of proximal tubule
injury, urinary kidney injury molecule-1 (KIM-1), is elevated in individuals with
CKD or with risk factors for CKD. METHODS: We measured urinary KIM-1 in
participants of five cohort studies from the USA and Sweden. Participants had a
wide range of kidney function and were racially and ethnically diverse.
Multivariable linear regression models were used to test the association of
urinary KIM-1 with demographic, clinical and laboratory values. RESULTS: In
pooled, multivariable-adjusted analyses, log-transformed, creatinine-normalized
urinary KIM-1 levels were higher in those with lower eGFR {? = -0.03 per 10
mL/min/1.73 m(2) [95% confidence interval (CI) -0.05 to -0.02]} and greater
albuminuria [? = 0.16 per unit of log albumin:creatinine ratio (95% CI
0.15-0.17)]. Urinary KIM-1 levels were higher in current smokers, lower in blacks
than nonblacks and lower in users versus nonusers of angiotensin-converting
enzyme inhibitors and angiotensin receptor blockers. CONCLUSION: Proximal tubule
injury appears to be an integral and measurable element of multiple stages of
CKD.
