Glomerular Diseases Topics [General] Nephritic Syndrome Nephrotic Syndrome Nephrotic Syndrome A predictable complex that results from a severe, prolonged increase in glomerular permeability for protein. Etiology and Classification Nephrotic syndrome (NS) occurs at any age but is more prevalent in children than in adults; in children, it is most common between ages 1 1/2 and 4 yr. There is a predilection for young males, but the sex distribution in older patients is more equal. Proteinuria is thought to occur through functional derangement of two mechanisms: the size-selective barrier leaks large protein molecules, and the charge-selective barrier fails to retain lower mol wt proteins. Diseases causing NS are listed in Table 224-7. Primary causes include minimal change disease, focal segmental glomerulosclerosis (FSGS), membranous glomerulonephritis (MGN), membranoproliferative glomerulonephritis (MPGN), and mesangial proliferative glomerulonephritis (GN). NS can also be due to secondary causes. Symptoms and Signs An early sign of NS is frothy urine due to protein. Other features include anorexia, malaise, puffy eyelids, retinal sheen, abdominal pain, and wasting of muscles. Anasarca with ascites and pleural effusions may occur.

Extractions: lipoid nephrosis Minimal change nephropathy is responsible for 90% of the cases of nephrotic syndrome in children less than 5 years of age. It also occurs in adults - approx 20%. The name is derived from the fact that the only detectable abnormality histologically is fusion and deformity of the foot processes under the electron microscope. Both light microscopy and immunofluorescence are unremarkable. The condition is most frequent in children aged between two and four years. It has been suggested that MCD is more common in atopic patients, especially those posessing HLA-DR7. However, a direct link between allergic sensitisation and the onset of MCD is yet to be established. MCD is steroid-responsive and, in general, does not lead to chronic renal failure.

Each kidney is made of more than a million units called nephrons. Each nephron has a tuft of blood vessels called a glomerulus, which is surrounded by a Bowman's Capsule. Together, these structures filter blood and form urine. Minimal change disease is one cause of nephrotic syndrome . It is named "minimal change" because the nephrons appear totally normal under a light microscope. The condition is only seen using an electron microscope, which reveals changes in the Bowman's Capsule in the nephrons. Urine tests also show high protein levels.
