What causes nephrotic range of proteinuria?
Nephrotic-range proteinuria may occur in other kidney diseases, such as IgA nephropathy. In that common glomerular disease, one third of patients may have nephrotic-range proteinuria. Nephrotic syndrome may occur in persons with sickle cell disease and evolve to renal failure.
How is nephrotic range of proteinuria diagnosed?
Proteinuria should be documented by a quantitative measurement e.g. urine protein: creatinine ratio (PCR) or albumin: creatinine ratio (ACR). PCR > 300-350 mg/mmol indicates nephrotic range proteinuria. Urgent referral to a nephrologist (ideally within 2 weeks) is necessary and a renal biopsy is usually performed.
What does nephrotic range mean?
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.
What is elevated in nephrotic syndrome?
Signs and symptoms of nephrotic syndrome include: Severe swelling (edema), particularly around your eyes and in your ankles and feet. Foamy urine, a result of excess protein in your urine. Weight gain due to fluid retention.
How much proteinuria is normal?
Normally, you should have less than 150 milligrams (about 3 percent of a teaspoon) of protein in the urine per day. Having more than 150 milligrams per day is called proteinuria.
What is a bad level of protein in urine?
There is a lot of protein in the urine (more than 1 gm/day). The higher the proteinuria, the greater the risk of kidney failure. People with proteinuria are also at risk of cardiovascular disease.
Can drinking more water reduce protein in urine?
Drinking water will not treat the cause of protein in your urine unless you are dehydrated. Drinking water will dilute your urine (water down the amount of protein and everything else in your urine), but will not stop the cause of your kidneys leaking protein.
