Childhood-onset nephrotic syndrome differs from the adult nephrotic syndrome in that the former often has a single common cause that typically responds well to steroid treatment. In adults, there are numerous potential causes, which makes an early kidney biopsy necessary to determine the correct diagnosis and treatment plan. [ 4 ]
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 ...
Similar to other causes of nephrotic syndrome (e.g., focal segmental glomerulosclerosis or minimal change disease), membranous nephropathy is known to predispose affected individuals to develop blood clots such as pulmonary emboli. Membranous nephropathy in particular is known to increase this risk more than other causes of nephrotic syndrome ...
[12] [13] [6] Other causes of edema that can promote a volume-overloaded state and predispose individuals to TACO include: heart failure, renal insufficiency, nephrotic syndrome, cirrhosis, and chronic venous insufficiency.

Nephrotic syndrome edema initially appears in parts of the lower body (such as the legs) and in the eyelids. In the advanced stages it also extends to the pleural cavity and peritoneum (ascites) and can even develop into a generalized anasarca. Hyperlipidaemia in nephrotic syndrome is typically caused by two mechanisms. [12]
[8] [9] If the condition is allowed to progress without treatment, it can eventually lead to azotemia and uremic symptoms. [9] This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia ...
Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [4] [5] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [5] with glomerular crescent formation seen in at least 50% [5] or 75% [4] of glomeruli seen on kidney biopsies.
The nephrotic syndrome is characterised by the finding of edema in a person with increased protein in the urine and decreased protein in the blood, with increased fat in the blood. Inflammation that affects the cells surrounding the glomerulus, podocytes , increases the permeability to proteins , resulting in an increase in excreted proteins.
