Androgen sulfate and glucuronide conjugates in nonhirsute and hirsute women with polycystic ovarian syndrome.

Peripheral androgen action largely determines the occurrence of hirsutism in women. Although serum 5 alpha-androstane-3 alpha, 17 beta-diol (3 alpha-diol) glucuronide signifies skin 5 alpha-reductase activity and has been used as a marker of hirsutism and peripheral androgen metabolism, other C19 androgen conjugates have recently been measured and may also be useful markers of hirsutism in women. In addition to normal controls we studied both hirsute and nonhirsute patients with polycystic ovarian syndrome who had similar levels of circulating androgen precursors. In these three groups we measured various C19 sulfates and glucuronides including serum 3 alpha-diol glucuronide. Serum androgen precursors were elevated, but were equal in the hirsute and nonhirsute patients. Serum androsterone sulfate and glucuronide, and 3 alpha-diol sulfate and glucuronide clearly differentiated the hirsute from the nonhirsute group. Among the conjugates, androsterone glucuronide was most reflective of the difference between the two groups (100.3 +/- 28.0 versus 42.9 +/- 4.0 ng/ml, p less than 0.05). In hirsute compared with nonhirsute patients with polycystic ovarian syndrome, serum 3 alpha-diol glucuronide was increased by the smallest amount (32%), followed by androsterone sulfate (38%), 3 alpha-diol sulfate (59%), and androsterone glucuronide with the largest increase (134%). Serum androsterone glucuronide and 3 alpha-diol glucuronide both correlated with androstenedione and dehydroepiandrosterone sulfate in hirsute women but not in nonhirsute women. These data suggest that besides serum 3 alpha-diol glucuronide, other C19 sulfate and glucuronide conjugates may reflect peripheral androgen action.

Comparison of Diane 35 and Diane 35 plus finasteride in the treatment of hirsutism.

OBJECTIVE: To compare the clinical efficacy and safety of the combination of Diane 35 (2 mg of cyproterone acetate, and 35 microg of ethinyl estradiol) plus finasteride (5 mg), and Diane 35 alone in the treatment of hirsutism. DESIGN: Prospective randomized clinical study. SETTING: Outpatients in Erciyes University Medical School. PATIENT(S): Forty women with hirsutism were selected. INTERVENTION(S): For 1 year, group 1 patients (n = 20) were treated with Diane 35 alone (2 mg of cyproterone acetate and 35 microg of ethinyl estradiol) daily on days 5 to 25 of the menstrual cycle and group 2 patients (n = 20) with Diane 35 plus finasteride (5 mg daily). MAIN OUTCOME MEASURE(S): Hirsutism was graded at 6-month intervals using the Ferriman-Gallwey method. The basal hormone levels of total and free testosterone (T), androstenedione, DHEAS, and sex-hormone-binding globulin (SHBG) were measured by radioimmunoassay before the study. Total T, free T, SHBG, and DHEAS were also measured at 6-month intervals for 1 year. Multiscreen blood chemistry and side effects were evaluated during the treatment. RESULT(S): Thirty-four patients completed the 12-month study period. A significant decrease in the hirsutism score as compared to baseline was observed after 12 months with both Diane 35 treatment (mean +/- SD, 15.62 +/- 4.89 vs. 9.75 +/- 3.97) and Diane 35 plus finasteride treatment (16.27 +/- 6.90 vs. 8.38 +/- 4.44). The percentage decreases in the hirsutism score (mean percent +/- SD) were 30.26 +/- 14.56 vs. 34.70 +/- 11.60 at 6 months, 38.09 +/- 11.46 vs. 48.14 +/- 14.27 at 12 months in the Diane 35 and the Diane 35 plus finasteride groups, respectively. The percentage reduction in the hirsutism score in the Diane 35 plus finasteride group at 12 months was greater than in the Diane 35 group (P <.05). CONCLUSION(S): The percentage decrease in the hirsutism score at 12 months was higher in the Diane 35 plus finasteride group than in the Diane 35 group. We believe that Diane 35 plus finasteride is an effective and safe combination for the treatment of hirsutism.

Predictors of clinical response in hirsute women treated with spironolactone.

OBJECTIVE: To examine the clinical efficacy of low dose spironolactone in hirsute women. DESIGN: Retrospective. SETTING: Outpatient endocrinology clinic. PATIENTS: One hundred nine consecutive women prescribed 75 to 100 mg/d spironolactone for at least 4 months in whom adequate follow-up data were available. RESULTS: Hirsutism improved in 72% of the women. Women with regular menses, whether or not they used oral contraceptives (OCs), had the highest response rate to spironolactone (78%), whereas women with irregular menses who did not use an OC had the lowest response rate (55%). Favorable responses were associated with increased severity of hirsutism (P = 0.04) and lower serum dehydroepiandrosterone sulfate levels (P = 0.05). Responders and nonresponders did not differ significantly in age (P = 0.10), duration of hirsutism (P = 0.14), pretreatment serum testosterone (T) (P = 0.48), or body mass index (P = 0.11). However, when each parameter was divided into subsets, trends toward decreasing response were observed with increasing age, duration of hirsutism over 15 years, and increasing serum T level. CONCLUSION: Low-dose spironolactone improves hirsutism in a majority of hirsute women, irrespective of age, severity or duration of hirsutism, menstrual status, or serum hormone levels.

Finasteride in the treatment of hirsutism: new therapeutic perspectives.

OBJECTIVE: To determine of the clinical and hormonal effects of finasteride (Proscar; Merck, Sharp, and Dohme, Rahway, NJ) in the treatment of idiopathic hirsutism and hirsutism in patients with polycystic ovary syndrome (PCOS). DESIGN: Controlled clinical study. SETTING: Istitute of Obstetrics and Gynecology, University of Naples "Federico II." PATIENTS: Ten women affected by idiopathic hirsutism and 15 women with PCOS. INTERVENTIONS: Finasteride was administered orally at a daily dose of 5 mg for a period of 6 months. MAIN OUTCOME MEASURES: Rating of hirsutism with the Ferriman-Gallwey method; serum androgen assays. RESULTS: Finasteride produced a reduction in the average hirsutism scores ( > 50% in all patients), whereas no change was observed in serum T, androstenedione, and DHEAS levels. A significant reduction was measured in serum dihydrotestosterone and 3 alpha, 17 beta-androstenediol glucuronide levels. CONCLUSIONS: This study demonstrates that symptomatic hirsutism has to be considered as a skin disease associated with the increased activity of the 5 alpha-reductase. It also indicates that the selective 5 alpha-reductase inhibitor, finasteride, is very effective and well tolerated in the treatment of both idiopathic hirsutism and of hirsutism in patients with PCOS.

Comparison of Diane 35 and Diane 35 plus spironolactone in the treatment of hirsutism.

OBJECTIVE: To compare the clinical efficacy and safety of Diane 35 (cyproterone acetate [2] mg and ethinyl estradiol [35 microg]) plus spironolactone [100 mg] combination and Diane 35 alone in the treatment of hirsutism. DESIGN: Prospective clinical study. SETTING: Outpatients in Erciyes University Medical School. PATIENT(S): Fifty women with hirsutism. INTERVENTION(S): Group I patients (n = 22) were treated with Diane 35 alone and group II patients (n = 28) with Diane 35 plus spironolactone [100 mg]. MAIN OUTCOME MEASURE(S): The basal hormone levels total and free T, androstenedione, DHEAS, sex hormone-binding globulin (SHBG), and prolactin (PRL) were measured by RIA before the study. Free T, SHBG, and DHEAS were also measured at 6-month intervals for 12 months. Hirsutism was graded at 6-month intervals. RESULT(S): The basal hormone levels were similar between the groups. Hirsutism score significantly decreased at the end of the therapy in both groups. The reduction in hirsutism score in group II at 12 months was greater than in group I. But the scores before the treatment, at 6 and 12 months were similar between the groups. CONCLUSION(S): Although the actual hirsutism score and free T concentration are not significantly different between the two groups at 12 months, percentage change in the hirsutism score at 12 months was higher in the Diane 35 plus spironolactone group. Therefore, the addition of spironolactone to Diane 35 may have a synergistic effect on hirsutism score.

Recurrence rate of hirsutism after 3 different antiandrogen therapies.

BACKGROUND: Although antiandrogens are frequently and successfully used to treat hirsutism, little attention has been paid to optimal duration of treatment and recurrence rate after cessation of therapy. OBJECTIVE: Our purpose was to determine the recurrence rate of hirsutism after 3 different antiandrogen therapies. METHODS: Eighty-one hirsute women referred to a tertiary hirsutism clinic were assigned to one of three regimens: spironolactone 100 mg/day with an oral contraceptive, cyproterone acetate 50 mg/day on days 1 to 10 with an oral contraceptive, or flutamide 250 mg twice a day. Hirsutism scores according to the Ferriman-Gallwey scoring system and endocrine parameters were evaluated before, during, and 1 year after withdrawal of treatment regimens. RESULTS: Hirsutism scores decreased significantly and similarly in spironolactone, flutamide, and cyproterone acetate treatment groups. However, 1 year after withdrawal of treatment in all antiandrogen therapy groups, hirsutism returned. CONCLUSION: Antiandrogens are effective in the treatment of hirsutism. However, cessation of antiandrogen therapy is followed by recurrence.

Spironolactone as a single agent for long-term therapy of hirsute patients.

OBJECTIVE: To assess the androgen-suppressing effect of spironolactone, and the use of this drug as a single agent in the long-term therapy of hirsute patients with either polycystic ovary syndrome (PCOS) or idiopathic hirsutism (IH). Standard cyproterone acetate (CPA) treatment was used to evaluate the results obtained with spironolactone. DESIGN: Prospective randomized study. PATIENTS: Forty-six hirsute women were separated randomly into two groups, stratified for polycystic ovary syndrome. For 12 months, Group 1 (21 patients, 10 PCOS) received spironolactone only (200 mg/day). Group 2 (23 patients, nine PCOS) received CPA (50 mg/day) with ethinyl oestradiol (35 microgram/day). MEASUREMENTS: Ferriman-Gallwey clinical score for hirsutism and serum testosterone, androstenedione, and LH levels. RESULTS: In IH patients, hirsutism regressed equally with spironolactone (21 +/- 2-14.5 +/- 2) and CPA (23 +/- 2-13 +/- 2). In PCOS patients, the mean score for hirsutism after 12 months was significantly lower with CPA (12 +/- 1) than with spironolactone (16 +/- 1). Testosterone levels did not change with spironolactone; with CPA there was a decrease from baseline in PCOS (47% and 51%, 6 and 12 months) and IH patients (31% and 30%). Androstenedione levels also declined from baseline in CPA-treated PCOS patients (38% and 39%, 6 and 12 months). Androgen levels were significantly different between the groups after 6 and 12 months. LH levels decreased with CPA (72%) but not with spironolactone. CONCLUSION: Our results suggest that spironolactone used as a single agent is as effective as cyproterone acetate combined with oestradiol for long-term treatment of patients with idiopathic hirsutism. In PCOS patients, spironolactone is still effective for reducing hirsutism; however, for treatment of the hormonal or metabolic manifestations associated with PCOS, it may be necessary to combine spironolactone with either an antigonadotrophic agent or a drug that improves peripheral insulin sensitivity.

Steroid hormones in the adrenal venous effluents in idiopathic hirsutism under basal and stimulated conditions.

Steroid hormone concentrations in the peripheral blood and the adrenal veins were measured in the basal state and after ACTH stimulation in 5 patients with idiopathic hirsutism. The basal concentrations of the steroids in the adrenal veins of the patients with idiopathic hirsutism were not significantly different from a control group of 5 patients catheterized for investigation of pheochromocytoma. Following ACTH stimulation, the concentrations of the steroids in the adrenal veins were also not significantly different in the hirsute and the control groups except for the concentrations of DHA and DHAS which were higher in the patients with idiopathic hirsutism. 17-hydroxyprogesterone (17-OHP) concentrations after ACTH stimulation were lower in the hirsute group compared to the control population. It is concluded that patients with idiopathic hirsutism have a defect in the biosynthesis of cortisol proximal to the action of the 11 beta- and 21-hydroxylase enzymes, deficiencies of which have been previously considered to be the usual causes of hirsutism due to an adrenocortical abnormality. The lower 17-OHP concentrations in the hirsute group can be explained on the basis of deficiency of substrate for the action of the 17-hydroxylating enzyme, consequent to the postulated deficiency of 3 beta-hydroxysteroid dehydrogenase.

Two different pathogenetic mechanisms may play a role in acne and in hirsutism.

OBJECTIVE: Acne is one of the most common skin disorders. Androgens are known to play an important and possibly central role. Androgens secreted from ovaries and adrenal glands (androstenedione, dehydroepiandrosterone and its sulphate, testosterone) and target tissue-produced androgens (testosterone and its 5 alpha-reduced metabolite, dihydrotestosterone) have been implicated. Although the sebaceous gland and the hair follicle form a single morphological entity, the pilosebaceous unit, acne and hirsutism do not always appear concomitantly, thus leading to the supposition that these two structures may have different degrees of sensitivity to similar androgenic stimulation. DESIGN AND PATIENTS: To determine whether acne and hirsutism are the clinical expression of a different androgen metabolism at target tissue levels we studied 90 randomly selected patients who came to our Out-patient Department for diagnosis and treatment during the last 2 years with isolated acne of mild to severe degree and 52 patients with idiopathic hirsutism without acne or history of acne. Twenty-four women without acne or hirsutism and without a history of endocrine disease were studied as controls. MEASUREMENTS: In both groups of patients, plasma levels of sex hormone binding globulin, of dihydrotestosterone, and of 3 alpha-androstanediol and of its glucuronide were evaluated. In all patients the percentage of free testosterone and the testosterone/sex hormone binding globulin ratio were also calculated. RESULTS: Patients with acne and those with isolated hirsutism showed significantly decreased sex hormone binding globulin plasma levels. The values of the percentage free testosterone and those of the testosterone/sex hormone binding globulin ratio were, on the contrary, higher with respect to the controls, although there were no statistically significant differences between the two groups. Significantly increased plasma levels of dihydrotestosterone with respect to the controls were observed in patients with acne or in those with hirsutism. However, while all patients with hirsutism showed increased plasma values of 3 alpha-androstanediol and its glucuronide, all patients with acne showed plasma levels within the normal range, independently of the precursor plasma levels. CONCLUSIONS: Our results demonstrate that dihydrotestosterone is further reduced to 3 alpha-androstanediol and its glucuronide only in hirsute patients but not in acne patients. These results suggest that dihydrotestosterone may undergo different metabolic pathways at skin levels and support the hypothesis that the two clinical manifestations may be the expression of the different metabolic fate of dihydrotestosterone itself. Moreover, our results demonstrate that 3 alpha-androstanediol and its glucuronide cannot be used as plasma markers of target-tissue produced androgens in all hyperandrogenic conditions.

Clinical efficacy and safety of low-dose flutamide alone and combined with an oral contraceptive for the treatment of idiopathic hirsutism.

BACKGROUND AND OBJECTIVE: High doses of flutamide, which is the only antiandrogen that specifically blocks the androgen receptor, have recently been used with good clinical results in women with hirsutism. Since regression of hair growth requires long-term therapy, clinical and economic considerations are important. The use of the lowest efficacious dosage could reduce costs. This study was undertaken to compare safety and efficacy of a low dose of flutamide (125 mg twice daily) alone and in combination with a triphasic oral contraceptive (OC) in women with idiopathic hirsutism. PATIENTS: Flutamide was administered orally in a low dose of 125 mg twice daily for 12 months alone in women with no risk of pregnancy or during the use of an oral contraceptive. MEASUREMENTS: Women were seen every 3 months and were evaluated for hirsutism score, hormone and lipid measurements. DESIGN: The study, which was conducted as a prospective open trial, was proposed to patients with idiopathic hirsutism, that is, with serum androgen levels in normal range and LH/FSH ratio less than 2. RESULTS: A statistically significant decrease in hirsutism score as compared to baseline was observed after only 3 months with either treatment, flutamide alone (16.9 +/- 1.6 vs 14.2 +/- 1.7, P < 0.0001) or the combination of flutamide with OC (15.6 +/- 0.8 vs 11.9 +/- 0.8, P < 0.001). Three months after cessation of treatment a statistically significant decrease from baseline was observed in the two groups. Nevertheless, at 6 months post-treatment this decrease was still significant only in the group who took flutamide in combination with an oral contraceptive. Flutamide alone does not appear to modify the levels of lipoproteins. The association of flutamide with a triphasic formulation significantly increased the HDL-C levels. CONCLUSIONS: This study shows beneficial effects of a low dose of flutamide in women with idiopathic hirsutism. The addition of an oral contraceptive is judicious to prevent pregnancy and reduce recurrence of hirsutism after cessation of flutamide. Peripheral androgenic blockage does not modify lipid profiles and it might reduce the negative effect of oral contraceptive on HDL-C levels. The addition of electrolysis delays the recurrence of hirsutism after cessation of flutamide.

Idiopathic hirsutism or polycystic ovary syndrome?

Polycystic ovaries (PCO) were detected using ultrasound imaging in a series of 173 women who presented with significant hirsutism and in some cases with irregular menstruation. Patients were divided into 3 groups. Those with hirsutism and regular menstruation (cycles > 8 per year, Group 1, n = 96); those with hirsutism and oligomenorrhoea (cycles < 8 per year, Group 2, n = 44) and those with hirsutism and amenorrhoea (cycles < 2 per year, group 3, n = 33). These 3 groups were compared with subjects with normal ovaries and regular cycles of 26-34 days and without hirsutism (n = 29) and also with a group of women with PCO and regular cycles who had no sign of hirsutism (n = 90). PCO were found in 86% of Group 1, 97% of Group 2 and 94% of women within Group 3. The results suggest that the term 'idiopathic hirsutism' may not be appropriate. An abnormal biochemical test consisting of a luteinizing hormone level > 9 U/L, testosterone level > 2.2 nmol/L, sex hormone binding globulin < 32 nmol/L or free androgen index > 4.5 was 100%, 91% and 76% sensitive for detecting PCO amongst women with amenorrhoea, oligomenorrhoea and idiopathic hirsutism respectively.

Increase in H-Y antigen-positive lymphocytes in hirsute women: effects of cyproterone acetate and estradiol treatment.

To investigate a possible relationship between lymphocyte H-Y antigen expression and plasma androgen concentrations in hirsute women, 27 hirsute women were studied. A significant increase in the percentage of H-Y-positive lymphocytes was found in both hirsute women with idiopathic hirsutism [13.4 +/- 2.9% (+/- SD); n = 15] and hirsute women with the polycystic ovary syndrome (13.0 +/- 2.8%; n = 12) compared to that in normal women (10.0 +/- 1.9%; n = 30; P less than 0.0005). Plasma testosterone and androstenedione concentrations, % H-Y+ lymphocytes, and hirsutism scores diminished during oral cyproterone acetate (50 mg/day) and percutaneous estradiol (3 mg/day) treatment. Significant correlations between % H-Y+ lymphocytes and hirsutism scores (P less than 0.001), % H-Y+ lymphocytes and plasma T concentrations (P less than 0.01) were found. We conclude that 1) women can produce H-Y antigen in the same way as men; 2) hirsutism is associated with an increase in H-Y antigen; and 3) the antiandrogen cyproterone acetate reduces H-Y antigen expression on lymphocytes.

The role of the CAG repeat polymorphism in the androgen receptor gene and of skewed X-chromosome inactivation, in the pathogenesis of hirsutism.

The human androgen receptor (AR) gene contains a variable number of CAG repeats within exon 1. Shorter AR alleles, by increasing transactivation, may result in augmented AR-mediated sensitivity of the hair follicle. We have evaluated whether the number of CAG repeats, or if skewed inactivation of X-chromosome, favoring the presence of shorter AR alleles, influence hirsutism in women with and without hyperandrogenemia. Twenty-eight women with idiopathic hirsutism (normal serum androgens), 34 women with hyperandrogenic hirsutism (increased serum androgens), and 15 healthy control women were analyzed by evaluating the number of CAG repeats in genomic DNA, as well as the methylation pattern (after DNA digestion with HpaII), which allows identification of which allele is inactive. Despite marked differences among the groups in serum androgens, which were markedly increased in women with hyperandrogenic hirsutism as compared with women with idiopathic hirsutism and to controls, there were no significant differences among the groups in the number of CAG repeats. Moreover, skewed X-chromosome inactivation was found in 10 subjects (3 with idiopathic hirsutism, 5 with hyperandrogenic hirsutism, and 2 controls; P = 0.746) of the 67 women (14.9%) who were heterozygous for the AR gene. In several of these subjects, it was the shorter allele that was preferentially inactivated. In conclusion, neither the CAG repeat polymorphism in the AR gene, nor skewed X-chromosome inactivation, seem to play a significant role in the pathogenesis of hirsutism.

The prevalence of late onset congenital adrenal hyperplasia in hirsute women from Central Anatolia.

Late onset congenital adrenal hyperplasia (LO CAH) can be seen in association with polycystic ovary syndrome (PCOS) or idiopathic hirsutism (IH). The study aimed to find out the prevalence of LO CAH in Central Anatolia among hirsute women. Sixty-three patients with hirsutism were evaluated to determine the frequency of LO CAH by comparing them with their age and body mass index matched 28 healthy controls. Of those 63 hirsute women, 43 were diagnosed as PCOS, and 20 were diagnosed as IH. Following basal hormonal evaluation, all subjects underwent ACTH stimulation test and ACTH stimulated 17-hydroxyprogesterone (17-OH P), 11-desoxycortisol (11-DOC), cortisol (F), and dehydroepiandrosterone sulfate (DHEA-S) levels were determined in all subjects. ACTH stimulated 17-OH P, 11-DOC, and DHEA-S levels did not differ between groups. However, stimulated F levels were found to be higher in hirsute women (p<0.001). Six out of 63 (9.52%) patients with hirsutism met the criterion for 21 hydroxylase deficiency. We found no subject presumed to have 11-beta hydroxylase deficiency, but one subject in control group (3.57%) and two patients among PCOS subjects (4.65%) had exaggerated DHEA-S response which was suggestive of mild 3-beta hydroxysteroid dehydrogenase deficiency. In conclusion, the most frequent form of LO CAH seems to be due to 21 OH deficiency among women with PCOS and IH in Central Anatolia. Mild 3-beta HSD deficiency may also be an underlying cause for hirsutism and it may be seen without any clinical presentation. Adrenal hyperactivity is likely to be the main reason of hyperandrogenemia in women with hirsutism.

Plasma sex hormone-binding globulin and androgen levels in the management of hirsute patients.

Hirsutism in women is a manifestation of excessive androgen action. This may be due to excessive exposure, or to increased sensitivity, of peripheral tissues to androgens. The present study was undertaken to estimate the percentage of hirsute patients with hyperandrogenaemia and to examine the effect of correction of hyperandrogenaemia on the clinical presentation. Plasma testosterone, dihydrotestosterone, sex hormone-binding globulin (SHBG) and androstenedione were determined in 58 hirsute patients before and following 3 months therapy with dexamethasone, 0.5 mg nocte. Testosterone expressed as a function of SHBG (testosterone/SHBG) provides an index of the non-protein bound testosterone fraction. Plasma levels of androstenedione were significantly elevated in 28% of hirsute patients, testosterone in 31% and testosterone/SHBG was elevated in 52%. Five per cent of patients had an elevated androstenedione value together with a normal testosterone/SHBG value. A subgroup of 13 hirsute patients with oligomenorrhoea had significantly higher values for androstenedione and testosterone/SHBG than eumenorrhoeic hirsute patients, and plasma testosterone, androstenedione and testosterone/SHBG values were more frequently elevated. In hirsute patients dexamethasone therapy resulted in suppression of plasma testosterone and androstenedione values, a significant increase in plasma SHBG and a marked fall in testosterone/SHBG. Following treatment with dexamethasone hyperandrogenaemia was corrected in 64% of hirsute patients, a decrease in the rate of hair growth or a resumption of a normal menstrual pattern occurred in 70% and concordant hormonal and clinical changes occurred in 79% of patients. These observations indicate that the testosterone/SHBG ratio is a sensitive index of hyperandrogenaemia, the correction of which is associated with clinical improvement.

[Effectiveness of flutamide alone or combined with oral contraceptives in the treatment of hirsutism in women].

BACKGROUND: Flutamide is an antiandrogen devoid of other hormonal effects, except for a decrease in the secretion of adrenal androgens such as dehydroepidandrosterone sulphate (DHEA-s) and androstenedione. AIM: To assess the effectiveness of flutamide in the treatment of hirsutism, used as monotherapy or combined with oral contraceptives (OC). PATIENTS AND METHODS: Women with peripheral hirsutism (defined as the presence of normal serum androgen levels and normal ovulatory menstrual cycles) were assigned to receive flutamide alone (500 mg/day) or flutamide plus an OC (ethynylestradiol 0.03 mg and desogestrel 150 microg). Hirsute with hyperandrogenism (polycystic ovary syndrome) were assigned to receive flutamide plus an OC. The degree of hirsutism was assessed using a clinical score (Moncada) at three, six and twelve months of therapy. RESULTS: Twenty five women with peripheral hirsutism received flutamide alone and 18 receive flutamide plus the contraceptive. Eighteen women with polycystic ovary syndrome were studied. At three months, the reduction in hirsutism was 11.2, 15.9 and 24.7% in women with peripheral hirsutism receiving flutamide alone or flutamide plus OC and in hyperandrogenic women receiving flutamide plus OC, respectively. At twelve months, the figures were 57.2, 57.3 and 52.5% respectively. In hyperandrogenic women, at baseline and three months, serum testosterone levels were 0.96 and 0.42 ng/nl and serum DHEA-s levels were 2,980 and 1,490 ng/ml respectively. No collateral effects of treatment or elevations in serum transaminase levels were observed. CONCLUSIONS: Flutamide is effective in the treatment of hirsutism in women with normal or elevated androgen levels. Adding OC did not improve the efficacy of the drug.

Results of the ACTH stimulation test in hirsute women.

OBJECTIVE: To determine the incidence of late-onset congenital adrenal hyperplasia (LOCAH) due to 21-hydroxylase deficiency among hirsute women and to evaluate the results of the ACTH stimulation test with the clinical characteristics. STUDY DESIGN: Prospective, controlled study. One hundred women with hirsutism and 14 normally cycling women without hirsutism were included in this study at the Division of Reproductive Endocrinology, Department of Obstetrics and Gynecology, Cerrahpasa School of Medicine, Istanbul University. After basal serum progesterone (P) and 17 hydroxyprogesterone (17OHP) levels were determined, an ACTH stimulation test was performed on cycle day 3-5. The same parameters were checked 30 minutes later. We estimated the 21 hydroxylase activity by calculating the change in 17OHP (17OHP 30-0) and the summed rate of the change in P and 17OHP ([P30-0] + [17OHP30-01/30 minutes). The 95th percentile for these estimates in normal women were calculated, and values above three times the 95th percentile were considered to distinguish women with LOCAH due to 21-hydroxylase deficiency. RESULTS: The 95th percentile for 17OHP 30-0 and (P30-0) + (17OHP30-0)/30 minutes in normal women was 1.6 and 8.9 ng/dL/min, respectively. Regarding 17OHP 30-0 values, three women with hirsutism had levels above three times the 95th percentile of these estimates, and 28 women had estimates of more than the 95th percentile but less than threefold. Seventeen of 28 women had oligomenorrhea, and all had severe hirsutism. The women with severe hirsutism and oligomenorrhea had significantly higher ACTH-stimulated serum 17OHP levels and values for 17OHP 30-0 and (P30-0 + (17OHP30-0)/30 min) than did normally cycling women. CONCLUSION: The incidence of LOCAH due to 21-hydroxylase deficiency and mild 21-hydroxylase deficiency is 3% and 28%, respectively, in women with hirsutism. Clinical characteristics are not helpful in determining 21-hydroxylase deficiency. However, the incidence of 21-hydroxylase deficiency is more common among women with severe hirsutism and oligomenorrhea. The change in serum 17OHP 30-0 seems to be greater than the summed rate of change in serum 17OHP and P in the detection of 21-hydroxylase enzyme deficiency.

[Hirsutism and hypertrichosis in adults: investigations and treatment].

Hypertrichosis, characterized by increased hair growth located in non-androgen-dependent areas, does not justify the monitoring of hormone levels, conversely to hirsutism, with increased hair growth in androgen-dependent areas of the female genitals. Adult hypertrichosis is iatrogenic (minoxidil, ciclosporine, diazoxide or glucocorticosteroids), of metabolic origin (porphyria), nutritional (anorexia) or paraneoplastic (hypertrichosis lanuoginosa). Metabolic or general assessment can help clinical diagnosis. In non-iatrogenic hirsutism the following must be eliminated: 1) a virilizing tumor (ovarian, adrenal) when confronted with rapid progression or recent hirsutism, plasma testosterone (T)>1.5ng/ml and/or (adrenal tumor) DHEA-sulfate (DHEAS)>700 microgram/dl and associated with hypertension; 2) when confronted with characteristic signs of hirsutism, Cushing's syndrome (post-dexamethasone cortisol), hyperprolactinemia (pooled PRL), or acromegalia (IGF1). Measurement of 17-OH-progesterone at 8 am on the 4th day of the cycle detects the late manifestation homozygous forms of a 21-hydroxylase (21OHD) block. The more frequent forms are: 1) ovarian polymicrocystic or hirsutism-anovulation syndromes without other causes (LH/FSH, T, hyperinsulinemia, sonography); 2) functional adrenal hyperandrogenia (increased DHEAS without organic cause); 3) idiopathic hirsutism. Treatment can be local (discoloration, depilation, diathermo-coagulation, laser). Treatment of hirsutism of organic origin is etiologic. The inhibitory effects of glucocorticosteroids are mediated by 21OHD. The most effective treatments are anti-androgenic: cyproterone acetate, progesterone-like and anti-gonadotropic (contraceptive) agents; and the only product in France officially indicated in hirsutism , spironolactone (anti-mineralocorticosteroid); and flutamide, pure anti-androgen (probably hepatoxic). Finasteride (type II 5 alpha-reductase inhibitor) appears less effective. Estrogen-progestagen-like agents can be associated with anti-androgens. We should also mention the GnRH-agonists, and finally, dietetics and metformine (in cases of insulin-resistance).
