Abstract
Las enfermedades glomerulares y otras nefropatías proteinúricas han sido abordadas generalmente desde un punto de vista centrado exclusivamente en el compartimento glomerular. Sin embargo, la proteinuria no es únicamente una expresión de daño renal y un marcador de mayor riesgo cardiovascular, sino que interviene activamente en la progresión de la enfermedad renal crónica (ERC). La filtración excesiva de proteínas plasmáticas a través de la barrera de filtración glomerular ejerce un efecto tóxico sobre las células tubulares, promoviendo la activación de múltiples vías que, en última instancia, conducen a atrofia y fibrosis tubulointersticial. En los últimos años se han evaluado múltiples biomarcadores como predictores de progresión de ERC y eventos cardiovasculares en diferentes cohortes de población. No obstante, en la mayoría de los trabajos, los marcadores tubulares no han sido evaluados específicamente en pacientes con enfermedades glomerulares, sin disponibilidad de correlación histológica y limitando el estudio a un solo marcador tubular...
Glomerular and proteinuric kidney diseases have traditionally been approached exclusively from a glomerular perspective. However, proteinuria is not only an expression of kidney damage, increased cardiovascular events and adverse outcomes, but also a driver of chronic kidney disease (CKD) progression. Excessive filtration of plasma proteins across the glomerular filtration barrier exerts a toxic effect on tubular cells, promoting the activation of multiple pathways that ultimately lead to tubular atrophy and fibrosis and end-stage kidney disease (ESKD).Numerous biomarkers of tubular health and disease are currently been evaluated to provide a comprehensive assessment of kidney health and disease in CKD population. However, most tubular markers have not been specifically evaluated in patients with glomerular diseases, often lacking histological correlation, and limiting the evaluation to a single tubular marker...
