Advances in chronic kidney disease
The pathologic consequences of sodium retention in the CKD population can lead to hypertension, edema, and progressive disease. Sodium excess is responsible for increases in oxidative stress, which alters kidney vasculature. As progression of CKD occurs, hyperfiltration by remaining nephrons compensates for an overall decrease in the filtered load of sodium. In the later stages of CKD, compensatory mechanisms are overcome and volume overload ensues. Nephrotic syndrome as it relates to sodium handling involves a different pathophysiology despite a common phenotype. Extrarenal sodium buffering is also examined as it has significant implications in the setting of advanced CKD.
