WebApr 27, 2024 · Circulating permeability factors As mentioned above, several forms of INS, and in particular those resulting in non-genetic forms of FSGS, are characterized by the presence of circulating factors causing proteinuria. WebWhere capillary permeability is increased locally, either by damage to the vessel wall or by the action of histamine, a local swelling known as a weal is produced. If the hydrostatic pressure is increased, as in muscle tissue during exercise, the rate of formation of tissue fluid will be increased. Changes in the plasma content of less permeant ...

Pre- and post-exposure blood samples were assessed for circulating markers of intestinal barrier injury and inflammation. WebApr 21, 2024 · Several molecules (including soluble urokinase-type plasminogen activator receptor, cardiotrophin-like cytokine factor 1, and anti-CD40 antibody) have been proposed as the circulating factor that causes podocyte injury, but we still do not have a convincing candidate that can be measured and followed up in clinical practice.
WebOct 1, 2010 · Circulating permeability factors may be important in idiopathic nephrotic syndrome (INS) including focal segmental glomerulosclerosis (FSGS) and in recurrence after renal transplantation. WebMar 30, 2016 · Another circulating factor disease is focal segmental glomerulosclerosis (FSGS), and it is not clear if this is a distinct entity, or on the same spectrum, implicating the same circulating factor(s). These patients are mostly steroid resistant and often have a rapid relapse after transplantation.
WebThe term ‘permeability’ refers to the increased leakiness of the glomerular filtration barrier, leading to proteinuria. The evidence for a ‘circulating’ component of permeability factor in FSGS includes the following: (1) Primary FSGS can recur very rapidly after kidney transplantation (∼30% of cases in adults, >50% in children). WebMar 23, 2024 · Several circulating factors have been proposed and studied, broadly grouped into protease components such as soluble urokinase-type plasminogen activator (suPAR), hemopexin (Hx) and calcium/calmodulin-serine protease kinase (CASK), and other circulating proteases, and immune components such as TNF-α, CD40 and …
