What is the protein selectivity index?

What is the protein selectivity index?

The proteinuria selectivity index (SI) describes changes of the glomerular permeability for macromolecules. In the present study, we examine the implications of SI as a diagnostic (199 patients) and a prognostic (49 patients) marker in glomerular diseases.

What is selective glomerular proteinuria?

Glomerular proteinuria This is a sensitive marker for the presence of glomerular disease. Glomerular proteinuria can be subclassified as: selective (albumin and transferrin in urine) and nonselective (all proteins are present). In glomerular proteinuria, the major protein present is always albumin.

What is the first indication of nephrotic syndrome in children?

You may see swelling around your child’s eyes in the morning. Often, that’s the first sign. As time passes, the swelling may last all day, and you may see swelling in your child’s ankles, feet or belly.

Is nephrotic syndrome selective proteinuria?

Selective albuminuria is usually found in patients with minimal change nephrotic syndrome, nonselective proteinuria without hematuria associated with podocyte detachment (yellow arrows) is found in patients with membranous nephropathy, focal segmental glomerulosclerosis, and diabetic nephropathy, and nonselective …

How do you calculate selectivity index?

The tumor-selectivity index (TS) was calculated by the following equation: TS = mean CC50 against normal cells/mean CC50 against tumor cells.

What is nephrotic-range proteinuria?

Nephrotic-range proteinuria is typically defined as greater than 3 to 3.5 g of protein in a 24-hour urine collection; however, not all persons with this range of proteinuria have nephrotic syndrome.

How do you calculate nephrotic proteinuria?

A spot protein or albumin–to-creatinine ratio of > 3-3.5 mg protein/mg creatnine or a 24-hour urine collection showing > 3-3.5 g of protein is nephrotic-range proteinuria. Screening for proteinuria can be done using a urine dipstick or early-morning spot protein or albumin–to-creatinine ratio.

What findings are consistent with a child who has nephrotic syndrome?

A child with nephrotic syndrome may have:

  • Very high levels of protein (albumin) in the urine.
  • Low levels of protein in the blood.
  • Tissue swelling all over the body (edema), especially in the belly (ascites)
  • Weight gain from excess fluid.
  • High cholesterol levels in the blood.
  • Less urine.
