-
- Ahumada-del Castillo Syndrome belongs to a group of disorders affecting
- women, characterized by abnormal lactation (milk production) and an absence
- of menstrual periods. Its causes are not well understood, but the syndrome
- seems to result from microscopic tumors in the region of the brain or
- pituitary gland responsible for the production of certain reproductive
- hormones. Ahumada-del Castillo Syndrome is not correlated with pregnancy.
- It responds to pharmacological treatment for variable periods of time.
-
- Symptoms
-
- Onset of Ahumada-del Castillo Syndrome may occur at any time. The symptoms
- consist of galactorrhea( abnormal secretion of a milky substance from the
- nipples) and the absence of menstrual periods (amenorrhea). The breasts and
- nipples are of normal size and appearance, and the secondary sexual
- characteristics, such as hair distribution, voice, etc., also remain normal.
-
- Laboratory tests reveal elevated levels of prolactin, the hormone
- responsible for lactation after childbirth. In addition, they indicate low
- levels of gonadotropins, hormones such as Follicle Stimulating Hormone (FSH)
- which regulate the monthly ovulatory cycle.
-
- Causes
-
- Ahumada-del Castillo Syndrome represents a dysfunction of the pituitary-
- hypothalamic axis. This entity, which consists of the region of the brain
- called the hypothalamus and the nearby endocrine gland called the pituitary,
- produces a number of important hormones, including many involved in
- reproduction and milk production.
-
- The exact abnormality is not understood, but evidence suggests that small
- tumors in the pituitary-hypothalamic region sometimes cause the syndrome.
- The tumors are frequently microscopic in size, so that they are not
- recognized easily.
-
- Other, rarer causes of galactorrhea-amenorrhea syndromes include
- underlying disorders such as hypothyroidism, chronic use of dopamine
- antagonistic drugs (e.g., thorazine), and discontinuation of oral
- contraceptive regimens.
-
- Related Disorders
-
- Galactorrhea-amenorrhea syndromes include Chiari-Frommel Syndrome which is
- associated with pregnancy and Forbes-Albright Syndrome which is associated
- with demonstrable tumors in the sella turcica, a structure in the skull where
- the pituitary gland is located.
-
- Therapies: Standard
-
- Treatment of Ahumada-del Castillo Syndrome with drugs such as bromocriptine
- and lergotrile mesilate lower prolactin levels, stopping the abnormal milk
- secretion, and often restoring menstrual function. Small tumors may in some
- cases be removed surgically. Others may respond to radiation treatment.
- When the syndrome results from other underlying disorders, it resolves with
- their successful treatment.
-
- Therapies: Investigational
