Childhood-onset nephrotic syndrome is a kidney disorder characterized by severe proteinuria (excess proteins in the urine), hypoalbuminemia (low albumin levels in the blood), and edema (swelling) that affects approximately 2-7 per 100,000 children under 18 years of age annually.
In nephrotic syndrome, protein loss can be as great as 3.5 grams over 24 hours, much of which is albumin, itself leading to hypoalbuminemia. [3] In children, nephrotic syndrome is commonly a primary disease process that is largely idiopathic, although more genetic causes are being identified with the cost and accessibility of whole exome ...
Minimal change disease (MCD), also known as lipoid nephrosis or nil disease, among others, is a disease affecting the kidneys which causes nephrotic syndrome. [1] Nephrotic syndrome leads to the loss of significant amounts of protein to the urine (proteinuria), which causes the widespread edema (soft tissue swelling) and impaired kidney function commonly experienced by those affected by the ...
Primary causes of nephrotic syndrome are usually described by their histology: [21] Minimal change disease (MCD): is the most common cause of nephrotic syndrome in children. It owes its name to the fact that the nephrons appear normal when viewed with an optical microscope as the lesions are only visible using an electron microscope .
MPGN accounts for approximately 4% of primary renal causes of nephrotic syndrome in children and 7% in adults. [3] It should not be confused with membranous glomerulonephritis, a condition in which the basement membrane is thickened, but the mesangium is not.
Glomerulonephrosis is a non-inflammatory disease of the kidney presenting primarily in the glomerulus (a glomerulopathy) as nephrotic syndrome.The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids.
By contrast, nephrotic syndrome is characterized by proteinuria and a constellation of other symptoms that specifically do not include hematuria. [6] Nephritic syndrome, like nephrotic syndrome, may involve low level of albumin in the blood due to the protein albumin moving from the blood to the urine. [7]
Kidney disease usually causes a loss of kidney function to some degree and can result in kidney failure, the complete loss of kidney function. Kidney failure is known as the end-stage of kidney disease, where dialysis or a kidney transplant is the only treatment option.
