Mikroalbuminurie und Albuminurie: Differenzialdiagnose und therapeutische Konsequenzen

The occurrence of microalbuminuria or albuminuria indicates a disturbance of the barrier function of endothelial cells, basement membrane or of a structural-renal disease (including diseased podocytes). The prevalence of microalbuminuria in the general population is about 8 %, however, in high risk groups, prevalence rates of 50 % and more have been observed. Its incidence is strongly associated with increased cardiovascular morbidity and mortality. Blood pressure control and the blockade of the renin-angiotensin-aldosteron-system (RAAS), respectively, is the central mechanism to reduce cardio-vascular-renal end points as well as mortality.
