Cost effectiveness of routine gonadotropin and androgen measurements in hirsute women.

Many physicians routinely measure the gonadotropins PRL, LH, and FSH and the androgens dehydroepiandrosterone (DHEA), androstenedione (ADIONE), and testosterone, as well as testosterone's biologically active fractions in the evaluation of hirsute women. Is this cost effective? To answer this question, 38 consecutive premenopausal hirsute women were evaluated. Two women each had minor elevations in PRL and FSH, and 11 had minor elevations in LH. Three women had minor elevations in the LH/FSH ratio, and only one was above a ratio of 3, believed to be indicative of polycystic ovarian syndrome. Because these gonadotropin elevations did not correlate with the androgens measured and were of no value in the diagnosis or management of these women, they were not believed to be cost effective. Their routine measurements should be abandoned.

Corticosteroids and adrenal suppression. Characterising and avoiding the problem.

Glucocorticoids are used for a variety of illnesses. One of their major complications is suppression of the hypothalamic-pituitary-adrenal axis, rendering a patient unable to respond to stress. The risk of this suppression may be minimised by the use of short-acting glucocorticoid preparations, administration of the entire daily dose in the early morning, use of topical and intra-articular preparations where appropriate, and the use of alternate-day therapy where appropriate. Most importantly, glucocorticoids should be used cautiously when indicated, and the duration of therapy limited as much as possible.

Side-effects of spironolactone therapy in the hirsute woman.

Spironolactone, an aldosterone antagonist with antiandrogenic activities, is often used to treat hirsute women. Several investigators have reported beneficial effects of such treatment, but the dosages used and side-effects encountered differ in their reports. To clarify this issue, 26 consecutive premenopausal women with idiopathic hirsutism were prospectively evaluated during spironolactone treatment. Sixteen women initially received 100 mg spironolactone twice daily on days 4-21 of their menstrual cycles. In 11 women (68%), the dosage had to be decreased or the medication discontinued due to side-effects. The major side-effect, metrorrhagia with 14-day cycles, occurred in 9 women (56%). This side-effect, while not dangerous, was intolerable to these women. In one woman, spironolactone was discontinued because of urticaria and in another because of scalp hair loss. Ten women initially received 50 mg spironolactone twice daily on days 4-21 of their menstrual cycles. Two developed metrorrhagia, but no other side-effects were noted. Because of the incidence of metrorrhagia at higher dosages, we recommend that spironolactone be administered cyclically at a starting dosage of 50 mg twice daily on days 4-21 of the menstrual cycle. Alternatively, one may consider adding cyclical estrogen/progesterone therapy to continuous spironolactone therapy.
