macroalbuminuria

macroalbuminuria

(mak´rōalbū´-mənur´ēə),
n a type of albuminaria that is characterized by especially high levels of albumin in the urine (more than 300 mg in 1 day). This condition can be a symptom of many kidney diseases and disorders because its presence indicates that the kidney is leaking albumin (a protein found in blood). Also known as
proteinuria.

The disease is mainly characterized by macroalbuminuria, where in a single day presence of albumin in the urine increases over 300 milligrams.
In addition, angiotensin receptor blockers have been found to reduce macroalbuminuria.

Studies suggest that reducing A1C to less than 7% may reduce macroalbuminuria and that optimal control of hyperglycemia may help preserve renal function.
Both microalbuminuria and macroalbuminuria in individuals with DM are associated with increased risk of cardiovascular disease.
Microalbuminuria was defined as an albumin/creatinine ratio (ACR) of 22 to 220 mg/g in men and 31 to 220 mg/g in women, and macroalbuminuria was defined as an ACR[greater than or equal to]220 mg/g.

60) A seven-year, multicenter (N = 192), prospective study has shown that diabetic nephropathy regression (reversal of microalbuminuria to normoalbuminuria, or macroalbuminuria to micro- or normoalbuminuria) is associated with a higher polyunsaturated fatty acid to saturated fatty acid ratio, while nephropathy progression (normoalbuminuria becoming micro- or macroalbuminuria or microalbuminuria becoming macroalbuminuria) is associated with a reversal of that same ratio.
4) Approximately 25% of patients with type 2 diabetes show either microalbuminuria or macroalbuminuria 10 years after diagnosis.
