In nephrotic syndrome, the kidneys leak too much protein into urine, leading to a drop in the levels of protein in the blood. This causing swelling in the body, especially in the face, legs and feet. Children usually need to stay in hospital for monitoring and treatment the first time this happens. In a few children, the nephrotic syndrome does not get better with steroids, or keeps coming back (relapsing). If your doctor has told you that your child has a different type of nephrotic syndrome. Analysis was performed to identify children with new-onset nephrotic syndrome. The children were admitted to the Division of Pediatric Nephrology, Zabrze, during two periods: 1986-1995 (76 patients) and 1996-2005 (102 patients).
The main symptom of nephrotic syndrome is swelling in the body – this is called oedema. In children, the swelling is mainly around the eyes and in the legs and feet. The swelling happens because the kidneys leak a lot of protein in the urine . You cannot usually see the protein, though it can be found a simple urine test. Nephrotic syndrome is rare – about 1 in 50,000 children get nephrotic syndrome each year. It affects more boys than girls. It can happen in people of all ages, though often starts when a child is between 2 and 5 years old.
