Update on renal blood oxygenation level-dependent MRI to assess intrarenal oxygenation in chronic kidney disease.

abstract：BACKGROUND:The use of renal Kt/V (r-Kt/V) as an indicator for the need of dialysis initiation has been recommended in the NKF-DOQI guidelines. In analogy to clinical practice in peritoneal dialysis, a fall of r-Kt/V below a threshold of 2.0 per week may indicate inadequate renal toxin elimination. However, there are no...

abstract：:We have previously suggested that albumin in tubule fluid at concentrations found in the nephrotic syndrome (NS) binds furosemide, thereby diminishing diuretic effect. This mechanism may contribute to diuretic resistance in NS. If this hypothesis is correct, displacement of albumin from furosemide should restore diure...

Increased FGF23 activity results in hypophosphatemic disorders, while reduced activity is linked to hyperphosphatemic disorders.
