The prognosis for nephrotic syndrome under treatment is generally good although this depends on the underlying cause, the age of the person and their response to treatment. It is usually good in children, because minimal change disease responds very well to steroids and does not cause chronic kidney failure. Any relapses that occur become less frequent over time; the opposite occurs with mesangiocapillary glomerulonephritis, in which the kidney fails within three years of the disease developing, making dialysis necessary and subsequent kidney transplant. In addition children under the age of 5 generally have a poorer prognosis than prepubescents, as do adults older than 30 years of age as they have a greater risk of kidney failure.
