Reproductive outcome of women with 21-hydroxylase-deficient nonclassic adrenal hyperplasia.

CONTEXT: Because many women with 21-hydroxylase (21-OH)-deficient nonclassic adrenal hyperplasia (NCAH) carry at least one allele affected by a severe mutation of CYP21, they are at risk for giving birth to infants with classic adrenal hyperplasia (CAH). OBJECTIVE: Our objective was to determine the frequency of CAH and NCAH infants born to mothers with 21-OH-deficient NCAH. DESIGN AND SETTING: We conducted an international multicenter retrospective/prospective study. PATIENTS AND METHODS: The outcome of 203 pregnancies among 101 women with 21-OH-deficient NCAH was reviewed. The diagnosis of 21-OH-deficient NCAH was established by a basal or post-ACTH-stimulation 17-hydroxyprogesterone level of more than 10 ng/ml (30.3 nmol/liter). When possible, genotype analyses were performed to confirm CAH or NCAH in the offspring. RESULTS: Of the 203 pregnancies, 138 (68%) occurred before the mother's diagnosis of NCAH and 65 (32%) after the diagnosis. Spontaneous miscarriages occurred in 35 of 138 pregnancies (25.4%) before the maternal diagnosis of NCAH, and in only four of 65 pregnancies (6.2%) after the diagnosis (P < 0.002). Four (2.5%; 95% confidence interval, 0.7-6.2%) of the 162 live births were diagnosed with CAH. To date, 24 (14.8%; 95% confidence interval, 9.0-20.6%) children, 13 girls and 11 boys, have been diagnosed with NCAH. The distribution of NCAH children and their mothers varied significantly by ethnicity (P < 0.0001, for both). CONCLUSIONS: The risk of a mother with 21-OH-deficient NCAH for giving birth to a child affected with CAH is 2.5%; at least 14.8% of children born to these mothers have NCAH.

Adiponectin and resistin in PCOS: a clinical, biochemical and molecular genetic study.

BACKGROUND: We conducted a cross-sectional case-control study to evaluate the possible involvement of adiponectin and resistin in the pathogenesis of polycystic ovary syndrome (PCOS). METHODS: Seventy-six PCOS patients and 40 non-hyperandrogenic women matched for BMI and degree of obesity were included. Serum adiponectin and resistin levels, anthropometrical and hormonal variables, the 45 T-->G and 276 G-->T polymorphisms in the adiponectin gene, and the -420 C-->G variant in the resistin gene, were analysed. RESULTS: Serum adiponectin concentrations were reduced in PCOS patients compared with controls (P = 0.038) irrespective of the degree of obesity, whereas serum resistin levels were increased in overweight and obese women compared with lean subjects (P = 0.016), irrespective of their PCOS or controls status. The adiponectin and resistin polymorphisms were not associated with PCOS and did not influence serum levels of adiponectin, resistin and other clinical and hormonal variables. In a multiple regression model, the waist-to-hip ratio, free testosterone levels and age, but not insulin resistance, were the major determinants of hypoadiponectinaemia. CONCLUSIONS: PCOS patients present with hypoadiponectinaemia, in relation with abdominal adiposity and hyperandrogenism. Our present results suggest that hyperandrogenism and abdominal obesity, by reducing the serum levels of the insulin sensitizer adipokine adiponectin, might contribute to the insulin resistance of PCOS.

Weight gain and cardiovascular risk factors during smoking cessation with bupropion or nicotine.

Weight gain is frequent after smoking cessation, and may limit patient's will to quit and long-term success. Nicotine and bupropion are effective drugs for smoking withdrawal. However, their influence on weight gain, insulin resistance and other cardiovascular risk factors, as well as possible differences in obese and lean subjects, have not been fully evaluated. We randomised 25 lean and 25 obese smokers to receive either bupropion or nicotine patches. Clinical evaluation and lipid profile were performed at baseline and after treatment. Insulin resistance was also assessed at the end. Weight, BMI, waist-to-hip ratio, and diastolic blood pressure increased (p < 0.005), whereas lipid profile improved (p < 0.001) after smoking cessation independently of obesity at baseline or drug used. Obese patients had higher insulin resistance at the end (p < 0.05) regardless of drug used. Weight gain was inversely related to age (beta= - 0.125, R = 0.38, p = 0.046), and insulin resistance was related to obesity at baseline (beta = 0.85, R = 0.46, p = 0.02). In conclusion, weight gain after smoking cessation is not dependent on obesity or drug taken. A beneficial lipid profile is achieved after quitting smoking with either bupropion or nicotine patch in both obese and lean subjects.

Obesity, and not insulin resistance, is the major determinant of serum inflammatory cardiovascular risk markers in pre-menopausal women.

AIMS/HYPOTHESIS: Increased serum inflammatory markers have been found in obesity and insulin-resistant states, and could play a causative role in insulin resistance, atherosclerosis and cardiovascular disease. The polycystic ovary syndrome represents a human model of insulin resistance because both lean and obese polycystic ovary syndrome patients are insulin-resistant compared with non-hyperandrogenic women. We evaluated whether obesity, insulin resistance, or both, are related to the increased concentrations of inflammatory markers in pre-menopausal women. METHODS: We compared 35 patients with polycystic ovary syndrome and 28 healthy women, paired for BMI, prevalence of obesity and smoking. Measurements included serum inflammatory markers, BMI, waist-to-hip ratio, blood pressure, serum glucose, insulin, lipid and hormone concentrations, and insulin sensitivity index. RESULTS: The insulin sensitivity index was reduced in polycystic ovary syndrome patients compared with controls. However, no differences were observed between both groups in C-reactive protein, interleukin 6, tumour necrosis factor-alpha, soluble type 2 tumour necrosis factor receptor, and soluble intercellular cell adhesion molecule-1. When considering patients and controls as a whole, C-reactive protein and interleukin 6, were increased in obese subjects compared with lean women. Inverse correlations existed between insulin sensitivity index and C-reactive protein, interleukin 6, tumour necrosis factor-alpha, soluble type 2 tumour necrosis factor receptor, and soluble intercellular cell adhesion molecule-1. Only the weak correlation with C-reactive protein persisted after controlling for BMI. CONCLUSION/INTERPRETATION: Obesity, and not insulin resistance, is the major determinant of serum inflammatory cardiovascular risk markers in pre-menopausal women.

Quality of life and psychometric functionality in patients with differentiated thyroid carcinoma.

We studied the psychological performance and the quality of life in patients with differentiated thyroid carcinoma, either during treatment with chronic suppressive doses of levothyroxine, or during the withdrawal of levothyroxine needed to perform whole-body scanning with radioactive iodine, with those of appropriate healthy controls. Eighteen women with differentiated thyroid carcinoma and 18 euthyroid age-matched healthy women were recruited. Patients were studied the day before levothyroxine withdrawal (when in chronic mild or subclinical hyperthyroidism), 4-7 days later (when most patients had normal serum free thyroxine and free triiodothyronine levels), and the day before scanning (when in profound hypothyroidism). Controls were studied at one time point. When compared with controls, patients presented with impairment of several indexes during chronic suppressive levothyroxine therapy (total score, emotional, sleep, energy and social of the Nottingham Health Profile; mental health, general health and social function of the SF-36, and total score on Wais Digit Span; P<0.05 for all comparisons). Also, quality of life indexes (19 of 21 scores), cognitive tests (6 of 12 scores), and affective and physical symptoms visual mental scales (18 of 19) worsened during profound hypothyroidism (P<0.05 for all comparisons). Quality of life and cognitive performance were almost comparable with those of euthyroid controls when most patients had normal free thyroxine and triiodothyronine levels. In conclusion, quality of life and psychometric functionality in patients with differentiated thyroid carcinoma is not only affected by withdrawal of levothyroxine but also by long-term treatment with supraphysiological doses of levothyroxine.

Role of the pentanucleotide (tttta)(n) polymorphism in the promoter of the CYP11a gene in the pathogenesis of hirsutism.

OBJECTIVE: To determine if the (tttta)(n) repeat polymorphism in the promoter region of CYP11a gene is associated with hirsutism and hyperandrogenism in women from Spain. DESIGN: Controlled clinical study. SETTING: Tertiary-care institutional hospital. PATIENT(S): Ninety-two hirsute women and 33 healthy control women. INTERVENTION(S): Basal and adrenocorticotropin-stimulated serum samples and genomic DNA extracted and purified from whole-blood samples were obtained during the follicular phase of the menstrual cycle. MAIN OUTCOME MEASURE(S): CYP11a (tttta)(n) repeat-polymorphism genotype and serum ovarian and adrenal androgen levels. RESULT(S): None of the CYP11a (tttta)(n) polymorphic alleles was associated with hirsutism. The absence of the four-repeat-units allele (4R-- genotype), which has been reported by other authors to be associated with polycystic ovary syndrome (PCOS), was found in 22.4% of the women studied here and was equally distributed among patients and controls, independently of the presence of PCOS and/or ovarian or adrenal hyperandrogenism. No differences were observed in serum hormone concentrations in 4R-- individuals as compared with subjects with at least one four-repeat-units allele. CONCLUSION(S): The (tttta)(n) repeat polymorphism in the promoter region of CYP11a does not appear to play any significant role in the pathogenesis of hirsutism and hyperandrogenism in women from Spain.

Role of the follistatin gene in women with polycystic ovary syndrome.

OBJECTIVE: To search for mutations in the coding exons of the follistatin gene of women diagnosed with polycystic ovary syndrome (PCOS). DESIGN: Controlled clinical study. SETTING: Tertiary institutional hospital. PATIENT(S): Thirty-four women diagnosed with PCOS and 15 healthy control women. INTERVENTION(S): Whole blood and serum samples were collected during the follicular phase of the menstrual cycle. MAIN OUTCOME MEASURE(S): Circulating total testosterone (T), sex hormone-binding globulin (SHBG), calculated free T (FT), androstenedione (A), dehydroepiandrosterone-sulfate (DHEAS), LH, FSH, E2, and basal and adenocorticotropic hormone (ACTH)-stimulated 17-hydroxyprogesterone (17-OHP) were determined. Insulin resistance was estimated from fasting glucose and insulin levels, using the homeostasis model assessment. The coding regions of the follistatin gene were studied by heteroduplex analysis after polymerase chain reaction amplification. RESULT(S): Women with PCOS presented with higher body-mass index, insulin resistance, T, FT, A, and ACTH-stimulated 17-OHP serum concentrations and lower SHBG serum levels, as compared with controls. No differences were observed among the groups in serum DHEAS, basal 17-OHP, E(2), LH, and FSH. No mutations were found in coding regions of the follistatin gene, with the exception of a G to A change at cDNA position 951, resulting in a silent mutation. This change was present in 2 (5.9%) of 34 patients and 1 (6.7%) of 15 controls. CONCLUSION(S): Mutations in the coding regions of the follistatin gene do not appear to be related to PCOS.

Screening for mutations in the steroidogenic acute regulatory protein and steroidogenic factor-1 genes, and in CYP11A and dosage-sensitive sex reversal-adrenal hypoplasia gene on the X chromosome, gene-1 (DAX-1), in hyperandrogenic hirsute women.

Abstract Abnormalities in adrenal and/or ovarian steroidogenesis are found in most patients with hirsutism. The rate-limiting step in the synthesis of steroids in the ovary and the adrenal is the conversion of cholesterol into pregnenolone by cholesterol side-chain cleavage enzyme (P450scc), encoded by the gene CYP11A, after cholesterol is introduced into the mitochondria by the steroidogenic acute regulatory protein (StAR). DAX-1 is a repressor of StAR gene expression, and steroidogenic factor-1 (SF-1) is a regulator of CYP11A, DAX-1, and StAR gene. Mutations in any of these factors resulting in gain of function, or loss of repression, of StAR or P450scc might contribute to the steroidogenic abnormalities present in hirsute patients. In the present study we have screened, using heteroduplex analysis, the genes encoding StAR and SF-1 as well as DAX-1 and CYP11A for mutations in genomic DNA from 19 women presenting with hirsutism and increased serum androgen levels. When variants were found, analysis was extended to a larger group of hyperandrogenic patients and nonaffected women. Two variants were identified in the SF-1 gene. A G-->C change in exon 6, resulting in an Arg(365)Pro mutation, was found in 1 of 45 patients, but not in controls. Also, a Gly(146)Ala missense mutation, resulting from a G-->C change in exon 4, was found in 2 of 48 patients and in 2 of 50 nonaffected individuals. We identified a C-->T base pair change at position -33 of the StAR gene. Three of 48 patients and 3 of 43 controls presented this variant. No mutations were found in coding regions of the StAR gene. Analysis of CYP11A-coding regions identified a G-->A change in exon 3, resulting in a Val(179)Ile missense mutation. This mutation was found in 1 of 29 patients studied and was not present in 50 controls. Finally, analysis of DAX-1 showed no variant in any of the women studied. In conclusion, mutations in StAR, SF-1, CYP11A, and DAX-1 are seldom found in hirsute patients and do not explain the steroidogenic abnormalities found in these women.

TNF-alpha and hyperandrogenism: a clinical, biochemical, and molecular genetic study.

To evaluate the role of TNF-alpha in the pathogenesis of hyperandrogenism, we have evaluated the serum TNF-alpha levels, as well as several polymorphisms in the promoter region of the TNF-alpha gene, in a group of 60 hyperandrogenic patients and 27 healthy controls matched for body mass index. Hyperandrogenic patients presented with mildly increased serum TNF-alpha levels as compared with controls (mean[median] +/- SD: 7.2[7.0] +/- 3.3 pg/ml vs. 5.6[4.4] +/- 4.0 pg/ml, P < 0.02). Although no differences in body mass index and insulin resistance indexes were observed between patients and controls, when subjects were classified by body weight, serum TNF-alpha was increased only in lean patients as compared with lean controls, but this difference was not statistically significant when comparing obese patients with obese controls. The TNF-alpha gene polymorphisms studied here (-1196C/T, -1125G/C, -1031T/C, -863C/A, -857C/T, -316G/A, -308G/A, -238G/A, and -163G/A) were equally distributed in hyperandrogenic patients and controls. However, carriers of the -308A variant presented with increased basal and leuprolide-stimulated serum androgens and 17-hydroxyprogesterone levels when considering patients and controls as a group. No differences were observed in serum TNF-alpha levels, body mass index, and insulin resistance indexes, depending on the presence or absence of these variants. In conclusion, our present results suggest that the TNF-alpha system might contribute to the pathogenesis of hyperandrogenism, independent of obesity and insulin resistance. However, elucidation of the precise mechanisms underlying the relationship between the TNF-alpha system and androgen excess is needed before considering TNF-alpha as a significant contributing factor to the development of hyperandrogenism.

Receiver operating characteristic analysis of the performance of basal serum hormone profiles for the diagnosis of polycystic ovary syndrome in epidemiological studies.

OBJECTIVE: We have used receiver operating characteristic (ROC) analysis to determine the diagnostic performance of several serum parameters, in order to evaluate their potential usefulness in establishing the diagnosis of polycystic ovary syndrome (PCOS) in epidemiological studies. DESIGN: Prospective study. METHODS: One hundred and fourteen women reporting spontaneously for blood donation were included in the study. Menopausal and oral contraceptive-treated women were excluded. Serum samples were obtained at the moment of donation, independently of fasting, time of day or day of menstrual cycle. Measurements included total testosterone, sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), LH, FSH and estradiol. The free testosterone (FT) concentration and the free androgen index (FAI) were calculated from testosterone and SHBG levels. ROC curves were calculated for all these serum determinations. RESULTS: Eight patients were diagnosed with PCOS, according to the presence of oligomenorrhea, hirsutism, acne and/or hyperandrogenemia, and exclusion of non-classic congenital adrenal hyperplasia, hypothyroidism and hyperprolactinemia. Of the parameters studied SHBG, FAI, FT and DHEAS were considered adequate measures for the diagnosis of PCOS. For example, serum SHBG levels showed an area under the ROC curve of 0.875+/-(S.E.(w))0.045 (95% confidence interval 0.800-0.929). A SHBG decision threshold <37 nmol/l had a sensitivity of 87.5%, a specificity of 86.8%, a positive likelihood ratio of 6.63, and a negative likelihood ratio of 0.14, for the diagnosis of PCOS. CONCLUSIONS: Our present results strongly suggest that decreased SHBG levels, and increased FAI, free testosterone concentration and DHEAS concentrations, are highly effective as single analytical procedures in epidemiological studies for the detection of PCOS in women of reproductive age.

Treatment of hirsutism with ethinyl estradiol-desogestrel contraceptive pills has beneficial effects on the lipid profile and improves insulin sensitivity.

OBJECTIVE: To evaluate the effects on the lipid pattern and insulin sensitivity of hirsute women of an oral contraceptive pill containing 30 microg of ethinyl estradiol and 150 microg of desogestrel. DESIGN: Prospective clinical study. SETTING: Tertiary care institutional hospital. PATIENT(S): 16 hirsute women. INTERVENTION(S): Women were evaluated at baseline and after receiving six cycles of oral contraceptive therapy. MAIN OUTCOME MEASURE(S): Body mass index (BMI); hirsutism score (nine body areas); serum levels of total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, apolipoprotein B, lipoprotein(a), and serum adrenal and ovarian androgens; and fasting glucose and insulin concentrations. RESULT(S): The mean serum total, HDL, and LDL cholesterol levels increased after six cycles of oral contraceptive therapy. Levels of HDL cholesterol were < 50 mg/dL in 7 of the 16 patients at baseline; these levels normalized in 4 patients after treatment. Serum total and LDL cholesterol remained within the normal range in all patients before and after therapy. No significant changes were observed in serum triglyceride, apolipoprotein B and lipoprotein(a) concentrations. Fasting insulin levels and insulin resistance as analyzed by homeostasis model assessment were reduced significantly after therapy. No changes in BMI were observed. Administration of oral contraceptive pills signifiCantly reduced the hirsutism score and hyperandrogenemia. CONCLUSION(S): Oral contraceptive pills containing low-dose ethinyl estradiol and desogestrel are effective in controlling hyperandrogenism and hirsutism and ameliorate the abnormal metabolic profile of women with hirsutism.

Effects of normalization of GH hypersecretion on lipoprotein(a) and other lipoprotein serum levels in acromegaly.

BACKGROUND & AIMS: Lipoprotein(a) has been recognized as an important risk factor for cardiovascular disease. Lipoprotein(a) has been found to be elevated in sera of acromegalic patients, possibly contributing to the increased incidence of coronary heart disease found in these patients. In the present study we sought to determine the effects of GH hormonal status on lipoprotein(a) and other lipid parameters, including lipoprotein lipase (LPL) activity. DESIGN: Cross-sectional study. PATIENTS: Twenty acromegalic patients, with either active (n = 12) or controlled (n = 8) acromegaly, were studied. Twenty-nine healthy subjects served as control group for serum lipid measurements. MEASUREMENTS: Serum GH, IGF-1, IGF binding protein-3 (IGFBP-3) and insulin levels were measured in patients. Insulin resistance was measured by the homeostatic model assessment (HOMA). Plasma total cholesterol, triglycerides, HDL-lipids, apolipoproteins A-I and B, lipoprotein(a) and lipoprotein lipase activity were also measured. RESULTS: The highest lipoprotein(a) levels were observed in patients with active acromegaly, followed by patients with controlled acromegaly, whose lipoprotein(a) concentrations were still significantly higher than those of the control group (means +/- SEM: active acromegaly, 0.67+/-0.13 g/l; controlled acromegaly, 0.41+/-0.12 g/l; controls 0.17+/-0.02 g/l; P<0.05). There were no differences in other lipid and lipoprotein values among the groups. In patients, significant correlations were observed between lipoprotein(a) and basal GH levels (r = 0.56, P<0.02), mean GH levels (r = 0.48, P<0.05) and with insulin resistance estimated by HOMA (r = 0.62, P<0.01). No correlations were found between lipoprotein(a) and IGF-1 or IGFBP-3 levels. CONCLUSIONS: Our present results demonstrate that both active acromegalic patients and those with controlled disease have elevated serum lipoprotein(a) concentrations. The findings might suggest that the present biochemical criteria for cure of acromegaly are not strict enough to result in the normalization of all the undesirable metabolic changes found in this disease, and also that significant cardiovascular risk may persist despite successful treatment of acromegaly.

High prevalence of the polycystic ovary syndrome and hirsutism in women with type 1 diabetes mellitus.

The current recommendation for strict metabolic control of type 1 diabetes mellitus requires the administration of supraphysiological doses of insulin, which might result in insulin-mediated stimulation of androgen synthesis, as occurs in insulin-resistant states. At present, the prevalence of hyperandrogenic disorders in women with type 1 diabetes mellitus is unknown. Eighty-five women with type 1 diabetes mellitus were evaluated for symptoms and signs of hyperandrogenism. In 68 of the patients, several serum androgen and hormone concentrations were measured. The polycystic ovary syndrome (PCOS) was defined by the presence of menstrual dysfunction, together with clinical and/or biochemical evidence of hyperandrogenism, and exclusion of other etiologies. Eighteen healthy women, menstruating regularly, served as controls for the androgenic profiles. Thirty-three patients (38.8%) presented hyperandrogenic disorders (16 had PCOS, and 17 had hirsutism without menstrual dysfunction). Type 1 diabetic patients with PCOS presented increased serum total and free testosterone concentrations, and serum androstenedione levels, but had normal serum sex hormone-binding globulin and dehydroepiandrosterone-sulfate levels. Hirsute type 1 diabetic women without menstrual dysfunction presented normal serum androgen levels. There were no significant differences between hyperandrogenic and nonhyperandrogenic type 1 diabetes mellitus women in clinical variables such as the duration of diabetes, age at diagnosis of diabetes, conventional or intensive insulin therapy, mean daily insulin dosage, or metabolic control. In conclusion, women with type 1 diabetes mellitus have a high prevalence of hyperandrogenic disorders, including PCOS and hirsutism.

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.

Serum prostate-specific antigen concentrations are not useful for monitoring the treatment of hirsutism with oral contraceptive pills.

Prostate-specific antigen (PSA) is produced in several female tissues, under the regulation of steroid hormones. Serum PSA levels are increased in women with hirsutism, and they correlate with serum androgen levels. Therefore, as a marker of androgen excess, measurement of serum PSA may play a role in monitoring the treatment of hirsutism with contraceptive pills. Sixteen hirsute patients were included in the study. Clinical and biochemical variables, including serum PSA (using an ultrasensitive chemiluminescent immunoassay), total testosterone, sex hormone-binding globulin, androstenedione, dehydroepiandrosterone-sulfate, estradiol, and gonadotropin concentrations were recorded at baseline and after 3 and 6 cycles of treatment with a monophasic contraceptive pill containing ethynylestradiol and desogestrel. Twenty-seven healthy women served as controls for serum PSA level and for the serum androgen profile. Serum PSA levels were higher in hirsute patients, as compared with healthy women (mean +/- SEM: 0.014 +/- 0.003 vs. 0.006 +/- 0.001 microg/L, P < 0.02). Despite a marked decrease in serum androgens (total testosterone and androstenedione, calculated free testosterone and free androgen index; and dehydroepiandrosterone-sulfate) and in the hirsutism score, and a marked increase in sex hormone-binding globulin levels, serum PSA levels did not change and remained detectable in all the hirsute patients after 3 and 6 cycles of treatment with contraceptive pills. In conclusion, the increased serum PSA levels present in hirsute patients do not change during treatment with contraceptive pills and do not parallel the amelioration in hirsutism and the decrease in serum androgen concentrations that occur during this treatment. Thus, serum PSA measurements have no apparent role in the management of hirsute patients on oral contraceptive treatment, at least with the ultrasensitive assays currently available.

A prospective study of the prevalence of the polycystic ovary syndrome in unselected Caucasian women from Spain.

We prospectively estimated the prevalence of the polycystic ovary syndrome (PCOS), as defined by the NIH/NICHHD 1990 endocrine criteria, in a population of 154 Caucasian women of reproductive age reporting spontaneously for blood donation. Anthropometric data; the presence of hirsutism, acne, and androgenic alopecia; and the menstrual history were recorded by a single investigator. In 145 women, blood samples were also obtained for measurement of serum androgen levels. PCOS was defined by the presence of 1) oligomenorrhea, 2) clinical and/or biochemical hyperandrogenism, and 3) exclusion of hyperprolactinemia, thyroid disorders, and nonclassic 21-hydroxylase deficiency. Hirsutism was defined by a modified Ferriman-Gallwey score of 8 or more, acne was considered as a sign of hyperandrogenism when persistent after the second decade of life, and hyperandrogenemia was defined by an increase in circulating testosterone or dehydroepiandrosterone sulfate or an increase in the free androgen index above the 95th percentile of the control values derived from the nonhirsute, nonacneic women having regular menses who were not receiving hormonal therapy. PCOS was present in 10(6.5%), hirsutism was present in 11 (7.1%), and acne was present in 19 (12.3%) of the 154 women. Our results demonstrate a 6.5% prevalence of PCOS, as defined, in a minimally biased population of Caucasian women from Spain. The polycystic ovary syndrome, hirsutism, and acne are common endocrine disorders in women.

Prospective randomized study comparing the long-acting gonadotropin-releasing hormone agonist triptorelin, flutamide, and cyproterone acetate, used in combination with an oral contraceptive, in the treatment of hirsutism.

OBJECTIVE: To compare triptorelin, cyproterone acetate (CPA), and flutamide, in combination with an oral contraceptive, in the treatment of hirsutism. DESIGN: Prospective randomized study. SETTING(S): Tertiary care hospital. PATIENT(S): Thirty-nine hirsute women with idiopathic or functional ovarian hyperandrogenism. INTERVENTION(S): Patients were randomly assigned to receive triptorelin (3.75 mg IM every 28 days), CPA (100 mg/d orally on days 1-10 of the menstrual cycle), or flutamide (250 mg orally twice daily). All the patients also received a triphasic oral contraceptive. MAIN OUTCOME MEASURE(S): Before and after 3 and 9 months of treatment, the Ferriman-Gallwey score, hepatic function, and gonadal and adrenal steroid profiles were evaluated. RESULTS: Thirty-three patients completed the 9-month study period. The Ferriman-Gallwey score decreased in all the groups. In the patients treated with CPA or flutamide, a decrease in the hirsutism score was noted as soon as after 3 months of treatment. This decrease was more pronounced after 9 months of treatment, especially in the patients who received flutamide, who had lower hirsutism scores compared with the other treatment groups. None of the patients had abnormal liver function test results. There was a mild increase in serum lipid concentrations, mostly in the group treated with triptorelin. CONCLUSION(S): Triptorelin, CPA, and flutamide are effective drugs for the treatment of hirsutism. Flutamide results in a greater reduction in the hirsutism score, but CPA also offers satisfactory results at a much lower cost. Triptorelin has no advantages over flutamide and CPA, and is the most expensive of the three drugs tested.
