Dexamethasone is used in gynecology for treatment of some types of menstrual disorders and related infertility. In most cases, these violations are innate and begins in utero. However, they are amenable to correction.
What is congenital adrenal hyperplasia
Adrenogenital syndrome - a disease caused by increased function of the adrenal cortex with the secretion of a large number of male sex hormones androgens, which inhibit the secretion of pituitary gonadotropins, which leads to disruption of the menstrual cycle and infertility.
Most often, the disease is hereditary and occurs in several children in the family since the birth. However, congenital adrenal hyperplasia may also occur in tumors of the adrenal cortex, in which case his symptoms appear at any age.
The development of this disease in congenital hyperplasia
Hyperplasia - do not be afraid
adrenal cortex caused by inherited disorders of the adrenal hormone synthesis due to deficiency of certain enzymes. In fact, congenital adrenal hyperplasia is the result of dysfunction of the adrenal cortex, at which there is increased formation of some steroid hormones (androgens) and a decrease in the formation of other (glucocorticosteroid hormone cortisol).
The deficit of cortisol
Cortisol - the hormone of the adrenal cortex
It leads to an increased release of pituitary adrenocorticotrophic hormone (ACTH), whose function is to stimulate adrenocortical secretion of cortisol for the purpose. This leads to the fact that the production of male sex hormones is further enhanced, and the urine, a large amount of 17-ketosteroids (the figure shows the high level of androgens in the blood).
How does congenital adrenal hyperplasia in women
The disease can manifest itself in several forms, but the main feature of all forms is the emergence of women of secondary male sexual characteristics: low voice, too expressed muscle development, body hair pubic hair of male type, with the advent of increased body hair mustache and beard. Often there is an increase of the clitoris and the cessation of menstruation.
If the disease girl begins in utero, that she often found anatomical changes of the external genitalia. This sometimes causes difficulty in determining the sex of the newborn. In the future, these girls quickly grow to approximately twelve years, after which growth is stopped due to the early closure of growth zones in the tubular bones.
Menstruation in these girls start late (15-16 years). The menstrual cycle is characterized by cyclic, long intervals between periods, the paucity of menstruation.
Based on what the diagnosis
Diagnosis is based on clinical examination and laboratory tests. The main laboratory test confirms the diagnosis of a urine sample for the presence of 17-ketosteroids. We investigate the number of levels of biologically active substances - precursor of androgens (17 UNP, T, DHEA, DHEA-S).
In order to distinguish the tumor from the adrenal cortex hyperplasia, patients underwent a test with dexamethasone. When tumor dexamethasone
Dexamethasone - one of the most effective glucocorticosteroids
It does not cause a decrease in the amount of urinary 17-ketosteroids, whereas hyperplasia this figure sharply reduced.
Ultrasound examination indicated the presence of ovarian follicles in the ovaries of varying degrees of maturity, which does not end with the maturation of ovulation
Ovulation - How to determine as accurately as possible?
. The dimensions of the ovaries may be somewhat larger than the norm.
Treatment adrenogenitelnogo syndrome using deksometazona
Today, congenital adrenal hyperplasia often treated using deksometazona that performs in this case replacement function. Assigned daily administration of dexamethasone in a small dose. The effectiveness of the treatment is carried out using urine 17-ketosteroids. The use of dexamethasone contributes to the normalization of the menstrual cycle, ovulation and normal appearance corresponding menstrual cycle, changes in the mucous membrane of the uterus (by ultrasound). It is also possible pregnancy, in which case the hormonal support of pregnancy continues to term the formation of the placenta (up to 13-16 weeks), which then takes over all functions to support pregnancy.
Women on treatment with dexamethasone are all male secondary sex characteristics.
Dexamethasone treatment of adrenogenital syndrome in women's effective and time-tested.
