Opis:
Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive hereditary diseases. The lack of cortisol synthesis leads to excessive stimulation of the adrenal glands by adrenocorticotropic hormone (ACTH). Moreover the impairment of cortisol synthesis results in adrenal hyperplasia and excessive androgen synthesis. Congenital adrenal hyperplasia is characterised by a considerable correlation between the genotype and the phenotype with the type of CYP21A2 gene mutation affecting the severity of 21-hydroxylase deficiency. The clinical manifestations of congenital adrenal hyperplasia in adults result from adrenocortical insufficiency, hyperandrogenism, and the adverse effects of glucocorticosteroids, which are used for the treatment of the syndrome. Non-classic congenital adrenal hyperplasia may sometimes have no clinical manifestation. Patients with classic congenital adrenal hyperplasia experience a wide variety of symptoms, including obesity, hypertension, hyperinsulinaemia, insulin resistance, and hyperleptinaemia. These abnormalities, the same as glucocorticosteroid treatment, promote the development of other diseases, such as metabolic syndrome, diabetes mellulitis, cardiovascular diseases and psychosocial problems. Moreover glucocorticosteroids treatment increases risk of osteoporosis and dermatological disorders. The maladies are more often seen in patients suffering from congenital adrenal hyperplasia syndrome than in the general population. Patients suffering from congenital adrenal hyperplasia require systematic evaluation of biochemical parameters (17-hydroxyprogesterone and androstendion) the same as clinical parameters (body mass index, waist circumference, glucose, lipids, blood pressure). Medical care for patients suffering from congenital adrenal hyperplasia should be provided by reference centres. Patients require cooperation between an endocrinologist, diabetologist, gynaecologist, andrologist, urologist, sexuologist and psychologist.

Opis:
The aim of this paper is a straightforward presentation of the steroidogenesis process and the most common type of congenital adrenal hyperplasia (CAH) - 21-hydroxylase deficiency - as well as the analytical diagnostic methods that are used to recognize this disease. CAH is a family of common autosomal recessive disorders characterized by impaired adrenal cortisol biosynthesis with associated androgen excess due to a deficiency of one or more enzymes in the steroidogenesis process within the adrenal cortex. The most common and prototypical example of the CAH disorders group (90-95%) is caused by 21-hydroxylase deficiency. Less frequent types of CAH are 11β-hydroxylase deficiency (up to 8% of cases), 17α-hydroxylase deficiency, 3β-hydroxysteroid dehydrogenase deficiency, P450 oxidoreductase deficiency and StAR deficiencies. In the 21-hydroxylase and 11β-hydroxylase deficiency, only adrenal steroidogenesis is affected, whereas a defect in 3β-hydroxysteroid dehydrogenase or 17α-hydroxylase also involves gonadal steroid biosynthesis. Many countries have introduced newborn screening programs based on immunoassays measuring 17-hydroxyprogesterone from blood spots used for other neonatal screening tests which enable faster diagnosis and treatment of CAH. Currently, chromatographic techniques coupled with mass spectrometry are gaining popularity due to an increase in the reliability of the test results.
