 [hi″per-fil-tra´shun]

reported that, after three years of treatment with hydroxyurea, there was a decrease in hyperfiltration, and the GFR dropped from 167 to 145ml/min; however, there was no change in urine microalbumin excretion [25].
The first occurs in childhood and adolescence, and it is distinguished by glomerular hyperfiltration. The second clinical phase is characterized by renal involvement with proteinuria, lipiduria, Malta crosses cristals in the urine sediment examined by polarized microscopy, impairment in the urine concentrating or diluting ability, and other renal dysfunctions.
Urine IgG and transferrin excretion has been previously observed in normoalbuminuric patients with diabetes and has been associated with hypertension and hyperfiltration [24, 25].
There is a spectrum of changes in CKD (Chronic Kidney Disease), which progress from hyperfiltration to micro to macroalbuminuria and finally renal failure.[20]
Nephron dose concept conveys that any reduction in nephron mass causes hyperfiltration and hemodynamically mediated glomerular injury [6].
The risk increases substantially with a lower eGFR, but also increases with eGFR >105 mL/min/[m.sup.2], likely representing the hyperfiltration seen with early diabetic nephropathy.
Unlike animal proteins, vegetable proteins do not induce renal vasodilation or glomerular hyperfiltration. In healthy subjects, the ingestion of animal protein induces kidney vasodilation and an increase in RPF and GFR, which is reversed by the sequential consumption of vegetable protein by the same individuals, who display a consistent rise in kidney vascular resistance during vegetable protein intake compared to animal protein ingestion."
The mechanism suggested for this, although not yet fully understood, involves systemic hypertension and intra-renal glomerular hyperfiltration, hypertrophy and/or tubular atrophy of cells (KHAN et al., 2015).
There are many methods for the removal of dyes such as coagulation, activated carbon absorption, electrochemical technique, electrochemical treatment, hyperfiltration, membrane separation, reverse osmosis, etc.
