Abstract:
Late-onset adrenal hyperplasia (LOAH) is the most common autosomal recessive disorder in the human. Partial 21-hydroxylase deficiency accounts for the vast majority of LOAH, but deficiencies in 11 β-hydroxylase and 3 β -hydroxysteroid dehydrogenase may also result in the disorder. These forms exhibit a great polymorphism in their clinical expression (variation in age at appearance and in degree of hyperandrogenism, and an association with abnormalities of the menstrual cycle). The incidence among women with clinical signs of hyperandrogenism varies from 1% to 35%. At present the only standard diagnostic criterion for LOAH with 21-hydroxylase deficiency is the level of 17-hydroxy progesterone after acute ACTH-stimulation. HLA-typing and purposeful genetic analysis advance the diagnosis. There is not any generally accepted approach for the diagnosis of the other two deffects. The correct diagnose of LOAH determines the therapeutical measures and follow-up of the patients.
Keywords: hyperandrogenism, congenital adrenal hyperplasia, late-onset adrenal hyperplasia, ACTH-test.
