Minimal change disease
is a kidney disorder that can lead to nephrotic syndrome, although the nephrons of the kidney look normal under a regular microscope. The most common symptom is swelling around the eyes, face, abdomen, and legs. Other features include poor appetite, weight gain, and a foamy appearance of the urine. The cause of minimal change disease is unknown, but it may occur following an allergic reaction, immunization, or viral infection. Treatment may involve the use of steroids such as prednisone. Children often respond better to this therapy than adults. Those who experience repeated relapses may benefit from the use of cytotoxic therapy, including cyclophosphamide, cyclosporine or chlorambucil.
