The normal range of GFR, adjusted for body surface area, is 100–130 average 125 mL/min/1.73m 2 in men and 90–120 ml/min/1.73m 2 in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 mL/min/1.73 m 2 until 2 years of age in both sexes, and then it progressively decreases. After age 40, GFR decreases ...
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m 2) in men and 90–120 (mL/min)/(1.73 m 2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2 ) until 2 years of age in both sexes, and then it progressively decreases.
The primary cause of the lack of clarity surrounding the GFR levels that indicate hyperfiltration is their strong reliance on age. [12] Glomerular hyperfiltration has traditionally been characterized as an elevated whole-kidney GFR, or a GFR greater than two standard deviations above the mean GFR of healthy individuals. [2]
A better estimate of kidney function is given by calculating the estimated glomerular filtration rate (eGFR). eGFR can be calculated without a 24-hour urine collection, using serum creatinine concentration and some or all of the following variables: sex, age, and weight, as suggested by the American Diabetes Association. [19]
Kidney dysfunction increases the risk of death and cardiovascular disease. [37] [38] Several studies have found that increased levels of cystatin C are associated with the risk of death, several types of cardiovascular disease (including myocardial infarction, stroke, heart failure, peripheral arterial disease and metabolic syndrome) and healthy aging.
In the United States, acute failure affects about 3 per 1,000 people a year. [8] Chronic failure affects about 1 in 1,000 people with 3 per 10,000 people newly developing the condition each year. [ 1 ] [ 10 ] In Canada, the lifetime risk of kidney failure or end-stage renal disease (ESRD) was estimated to be 2.66% for men and 1.76% for women ...
Infective endocarditis - Infection that affects the inner lining of the heart (endocardium) and can potentially cause a thrombus to form on one or more heart valves and, if left untreated, can cause septic emboli that can have many systemic effects, including deposition into the glomerulus, causing glomerulonephritis and nephritic syndrome. [25]
Hemoglobin-AGE levels are elevated in diabetic individuals [24] and other AGE proteins have been shown in experimental models to accumulate with time, increasing from 5-50 fold over periods of 5–20 weeks in the retina, lens and renal cortex of diabetic rats. The inhibition of AGE formation reduced the extent of nephropathy in diabetic rats. [25]
