Overview
The prognosis of congenital adrenal hyperplasia due to 21-hydroxylase deficiency is generally good with treatment. Common complications of 21-hydroxylase deficient congenital adrenal hyperplasia include Adrenal crisis, Infertility, and precocious puberty.
Natural History
While a child with simple virilizing congenital adrenal hyperplasia is taller than peers at that point, he/she will have far fewer years remaining to grow, and may go from being a very tall 7-year-old to a 62-inch 13-year-old who has completed growth.
Complications
Complications associated with 21-hydroxylase deficient congenital adrenal hyperplasia include:
Prognosis
Even after diagnosis and initiation of treatment, a small percentage of children and adults with infancy or childhood onset congenital adrenal hyperplasia die of adrenal crisis. Deaths from this are entirely avoidable if the child and his family understand that the daily glucocorticoids cannot be allowed to be interrupted by an illness. When a person is well, missing a dose, or even several doses, may produce little in the way of immediate symptoms. However, glucocorticoid needs are increased during illness and stress, and missed doses during time of illness can lead within hours to hypotension, shock, and death.
