So what is albuminuria?

An elevated urinary albumin excretion is a marker

  • f endothelial dysfunction; it symbolizes the kidney’s way
  • f translating the existence of vascular damage.

Prevalence of Albuminuria in the General Population

Low-Normal Albuminuria

0-10mg/24h 75%

Macroalbuminuria

>300 mg/24h 0.7%

Microalbuminuria

30-300 mg/24h 7.2%

High-Normal Albuminuria

11-29 mg/24h 16.6%

N = 40,856

The Significance of Albuminuria

  • Results from injury to systemic and glomerular

circulation (loss of glycocalyx)

  • When increased, associated with progressive

decline in renal function

  • Predicts new onset diabetes risk
  • When increased, associated with greater risk of

cardiovascular, cerebrovascular, and peripheral vascular disease
