The urine may also contain fat, which can be seen under the microscope. Alternative Names Nephrosis Causes, incidence, and risk factors Nephrotic syndrome is caused by various disorders that damage the kidneys, particularly the basement membrane of the glomerulus. This immediately causes abnormal excretion of protein in the urine. The most common cause in children is minimal change disease, while membranous glomerulonephritis is the most common cause in adults. This condition can also occur as a result of infection, use of certain drugs, cancer, genetic disorders, immune disorders, or diseases that affect multiple body systems including diabetes, systemic lupus erythematosus, multiple myeloma, and amyloidosis. It can accompany kidney disorders such as glomerulonephritis, focal and segmental glomerulosclerosis, and mesangiocapillary glomerulonephritis. Nephrotic syndrome can affect all age groups. In children, it is most common from age 2 to 6. This disorder occurs slightly more often in males than females. Symptoms Swelling (edema ) general around the eyes in the extremities, especially the feet and ankles Swollen abdomen Facial swelling Foamy appearance of the urine Weight gain (unintentional) from fluid retention Poor appetite High blood pressure Signs and tests Physical examination can detect some symptoms. Other symptoms and signs of causative disorders can also be found with examination. Urinalysis reveals large amounts of urine protein. Fats are often also present in the urine. Tests to rule out various causes may include the following: Glucose tolerance test Antinuclear antibody Rheumatoid factor Cryoglobulins Complement levels Hepatitis B and C antibodies VDRL serology Serum protein electrophoresis Kidney biopsy This disease may also alter the results of the following tests: Urinary casts Triglyceride Protein electrophoresis - urine Serum iron Cholesterol Albumin Treatment The goals of treatment are to relieve symptoms, prevent complications and delay progressive kidney damage.

Minimal change disease (1 image) (Doctor-Reviewed information)
Minimal change disease is a kidney disorder. 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 structure called the¿Bowman's Capsule. Together, these structures filter blood and¿produce urine. Minimal change disease is one cause of nephrotic syndrome. It is named "minimal change" because the nephrons appear totally normal under a light (regular)¿microscope. The condition is only seen using an electron microscope, which reveals changes in the glomeruli. Urine tests also show high protein levels. Reviewer: Colm C.
