Another proposed hypothesis for the collapsing variant of FSGS is aberrant repair with proinflammatory hyperplasia, which leads to fibrosis and atrophy of the injured parenchyma and impairs the glomerular capillary structure, thereby altering glomerular filtration (ll).
GFR, SNGFR, glomerular capillary pressure (PGd, single nephron plasma flow (Qa), single nephron filtration fraction (SNFF), afferent (AR) and efferent (ER) resistances, afferent (7A) and efferent (7rE) oncotic pressure and ultrafiltration coefficient (Kf) were calculated.
During plasma filtration in the glomeruli, the glomerular capillary wall discriminates among molecules of different size, charge, and configuration.
Glomerular proteinuria results from increased filtration of macromolecules such as albumin across the glomerular capillary barrier.
The obstruction also increases pressure on the system, decreasing GFR and contributing to afferent arteriole constriction via tubuloglomerular feedback, which results in decreased glomerular capillary filtration pressure (Porth, 2007).
These studies, among dozens of other similar studies in a large variety of models for hypertension, diabetes and kidney disease, illustrate that in a diseased animal (including humans) or an animal where there is already one existing factor, increasing glomerular capillary pressure with a reduction in renal mass is accompanied by an acceleration of renal disease.
Exercise increases glomerular permeability by influencing renal hemodynamic and by depleting negative charges on the glomerular capillary wall (Ala-Houhala, 1990).
The actions of ANP include vasodilation, increasing glomerular capillary pressure without altering blood flow (Porth, 2004).
WHO class III, or focal proliferative glomerulonephritis, is defined by the presence of proliferating endocapillary cells within the glomerular capillary loops.
1-5) Our patient suffered from both diseases, as evidenced by histological analyses: cortical necrosis and signs of thrombotic microangiopathy (fibrin-platelet thrombus material within the glomerular capillary lumina) and abnormal clotting parameters with low fibrinogen, high D-dimer levels and low platelet counts.
Because RAS blockers are designed to reduce glomerular capillary pressure, there will be a functional increase in serum creatinine or a decrease in estimated GFR.
The filtration barrier of the glomerular capillary bed consists of three layers, with the first being fenestrated endothelium.
