Glomerular endothelial cell (GEC) dysfunction due to oxidative stress and enhanced proinflammatory cytokines plays an important role in inducing proteinuria and procoagulant activity, namely blood hypercoagulability, hyperviscosity and local intravascular coagulation and altered hemorheology in NS. A dysfunctioning GEC releases fewer endothelium-dependent vasodilators but produces more vasoconstrictors. Severe intrarenal hemodynamic alteration associated with hemodynamic maladjustment with preferential constriction at the efferent arteriole has been uniquely implicated in severe GN and NS-FSGS. Such a constriction exerts three significant hemodynamic impacts. Proximal to the efferent arteriolar constriction, it induces (i) an overestimated GFR due to hyperfiltration and (ii) an elevated intraglomerular hydrostatic pressure. Distal to the efferent arteriolar constriction, it (iii) exaggeratedly reduces PTCF which correlates with the TIF.
