[Fertility disorders in 49 hyperandrogenic women desiring pregnancy. Treatment results aimed at obtaining a pregnancy in 40 hyperandrogenic infertile women and in 9 hyperandrogenic women desiring pregnancy].

The clinical and therapeutic aspects of fertility due to hyperandrogenism were studied in 49 women (40 presenting with sterility and 9 for another reason but seeking to become pregnant). Patients were divided into three main etiological groups on the basis of hormonal findings: ovarian (15 cases), adrenal (16 cases) and mixed (11 cases) hyperandrogenism. This study highlighted several points. 22% of infertile women had no cutaneous signs of hyperandrogenism and menstrual disturbances were missing in 46% of cases of adrenal hyperandrogenism. Primary infertility was seen more often in all types of hyperandrogenism (28 cases) than secondary infertility (12 cases). Secondary infertility was explained by a high early spontaneous abortion rate in hyperandrogenism (40%). This was much commoner in adrenal hyperandrogenism than in ovarian or mixed hyperandrogenism. Inducing treatment based upon a combination of dexamethasone and clomiphene citrate proved to be the most effective in these infertile women (86% pregnancy rate). The frequency of spontaneous abortions in infertility due to ovarian or mixed hyperandrogenism treated by clomiphene citrate alone can probably be explained by the persistence of hyperandrogenism.

The risk of functional ovarian hyperandrogenism and polycystic ovary syndrome in patients with hyperandrogenism.

To describe the presence of dysregulations in steroid biosynthesis and the risk of functional ovarian hyperandrogenism (FOH) and polycystic ovary syndrome (PCOS)-like development in children with hyperandrogenism, 28 girls were studied. Adrenal steroidogenic profile was defined by basal and ACTH-stimulated levels of 17OHP, cortisol, DHEAS and androstenedione, and delta precursor/delta product ratios. Ovarian hyperandrogenism was defined by 17OHP response to LHRH stimulation, and pelvic ultrasonography (US) was performed to evaluate ovarian morphology. Basal and ACTH-stimulated hormonal results revealed non-classical 21-hydroxylase deficiency-like status in one patient (3.6%), and 21-hydroxylase deficiency heterozygote carrier-like state in four patients (14.3%), while the other 23 patients (82.1%) had functional adrenal hyperandrogenism (FAH). Among these patients with FAH, 47.83% had FOH; when these patients were evaluated by pelvic US, 30.4% had morphological changes which were not concordant with their age. We suggest that even mild forms of hyperandrogenism must be considered seriously and dysregulations of the steroidogenic pathway and ovarian abnormalities must be evaluated carefully to determine the risk of FOH/PCOS.

Diagnosis of hyperandrogenism: clinical criteria.

Hyperandrogenism or androgen excess is a common endocrine disorder of women of reproductive-age, with a prevalence of 5-10%. The majority of patients with hyperandrogenism will have polycystic ovary syndrome. Hyperandrogenism presents a complex diagnostic challenge for both the practicing physician and the clinical investigator. Clinical manifestations of hyperandrogenism include hirsutism, acne, androgenic alopecia, and virilization. Hirsutism, defined as excessive growth of terminal hair in women in a male-like pattern, is the most commonly used clinical diagnostic criterion of hyperandrogenism. The presence of hirsutism is usually determined by using a standardized scoring system of hair growth. Depending on the definition, hirsutism is present in up to 80% of patients with hyperandrogenism. Acne and androgenic alopecia are other common androgenic skin changes, and might be observed without hirsutism in some hyperandrogenic women. However, isolated presence of any of these manifestations is not used as a diagnostic criterion for hyperandrogenism. Virilization is a relatively uncommon feature of hyperandrogenism, and its presence often suggests an androgen-producing tumor. A thorough history and a focused clinical examination are extremely helpful in diagnostic evaluation of patients with suspected hyperandrogenism.

Comment: the methionine 196 arginine polymorphism in exon 6 of the TNF receptor 2 gene (TNFRSF1B) is associated with the polycystic ovary syndrome and hyperandrogenism.

Inflammatory cytokines such as TNF alpha may play a role in the pathogenesis of common metabolic disorders, including hyperandrogenism and the polycystic ovary syndrome (PCOS). The TNF receptor 2 mediates most of the metabolic effects of TNF alpha. In the present study, we have evaluated serum soluble TNF receptor 2 levels, and several common polymorphisms in the TNF receptor 2 gene (TNFRSF1B), in women presenting with PCOS or hyperandrogenic disorders. Initial studies included 103 hyperandrogenic patients (42 presenting with PCOS) and 36 controls from Spain. The 196R alleles of the M196R (676 T-->G) variant in exon 6 of TNFRSF1B, which is in linkage disequilibrium with a CA-repeat microsatellite polymorphism in intron 4 of TNFRSF1B, tended to be more frequent in hyperandrogenic patients than in controls (P = 0.056), reaching statistical significance when the analysis was restricted to include only PCOS patients (P < 0.03). Extended analysis including another 11 hyperandrogenic patients from Spain and 64 patients and 29 controls from Italy confirmed the association between 196R alleles of the M196R variant and hyperandrogenic disorders (P < 0.05), which was maintained when restricting the analysis to PCOS patients (P < 0.02). On the contrary, the 3'-untranslated region (exon 10) variants 1663 G-->A, 1668 T-->G, and 1690 T-->C were not associated with hyperandrogenism. The soluble TNF receptor 2 levels were not different between patients and controls but were increased in obese subjects, compared with lean individuals, and were affected by the interaction between the 1663 G-->A and 1668 T-->G variants in the 3'-untranslated region of TNFRSF1B. The TNFRSF1B genotype did not influence any clinical or biochemical variable related to hyperandrogenism or insulin sensitivity and was not associated with obesity, both in hyperandrogenic patients and healthy controls considered separately. In conclusion, the M196R (676 T-->G) variant in exon 6 of TNFRSF1B is associated with hyperandrogenism and PCOS, further suggesting a role for inflammatory cytokines in the pathogenesis of these disorders.

Lack of an ovarian function influence on the increased adrenal androgen secretion present in women with functional ovarian hyperandrogenism.

OBJECTIVE: To evaluate whether ovarian function might have an influence on the adrenal hyperandrogenism present in patients with functional ovarian hyperandrogenism. DESIGN: Controlled clinical study. SETTING: Tertiary institutional hospital. PATIENT(S): Twenty-nine hirsute women with functional ovarian hyperandrogenism and 12 normal controls. INTERVENTION(S): The ACTH and GnRH tests were performed before and during triptorelin-induced ovarian suppression in patients. The normal women served as controls for the ACTH test. MAIN OUTCOME MEASURE(S): Basal and ACTH-stimulated steroid values. RESULT(S): All patients presented elevated T and free androgen index, which normalized after triptorelin. Patients with functional ovarian hyperandrogenism and adrenal hyperandrogenism, defined by elevated basal DHEAS (n = 10), presented enhanced delta 4-17, 20-lyase activity, which persisted during ovarian suppression. delta 4-17,20-lyase activity was normal in the functional ovarian hyperandrogenism patients without adrenal hyperandrogenism (n = 19). No correlation was observed between the any of the indexes of the adrenal enzymatic activities evaluated and plasma E2 or T. CONCLUSION(S): Increased adrenal delta 4-17,20-lyase activity is present in functional ovarian hyperandrogenism women with adrenal hyperandrogenism. No influence of the excess ovarian androgens or estrogens was found on any of the adrenal enzymatic pathways explored.

Insulin stimulates androgen accumulation in incubations of ovarian stroma obtained from women with hyperandrogenism.

The effects of insulin and insulin-like growth factors (IGFs) on ovarian androgen production were examined in ovarian stroma obtained from four women with hyperandrogenism and three women without hyperandrogenism. In incubations of stroma obtained from all four hyperandrogenic patients, insulin alone (500 ng/ml) significantly stimulated androstenedione and testosterone release. LH alone (25 ng/ml) significantly stimulated androstenedione release in incubations of stroma obtained from three of the four hyperandrogenic patients and testosterone release in incubations of stroma obtained from one of the four hyperandrogenic patients. In stromal incubations from three of the four hyperandrogenic patients, insulin alone (500 ng/ml) resulted in a significantly greater release of androstenedione and testosterone than did LH alone (25 ng/ml). Dihydrotestosterone was released in measurable quantities in incubations of stromal tissue obtained from three of the four hyperandrogenic women. In all three instances in which dihydrotestosterone was detectable, insulin alone (500 ng/ml), but not LH alone (25 ng/ml), significantly stimulated dihydrostestosterone release. Incubations of stroma obtained from three nonhyperandrogenic, normally cycling women demonstrated low levels of androstenedione release and negligible testosterone and dihydrotestosterone release. Insulin alone (500 ng/ml) and LH alone (25 ng/ml) produced no significant increase in androstenedione release. Insulin (500 ng/ml) plus LH (25 ng/ml) significantly stimulated androstenedione accumulation in stroma obtained from two of the nonhyperandrogenic women. One insulin dose-response experiment was performed using stromal tissue obtained from a hyperandrogenic woman. In this experiment, insulin, at a dose of 50 ng/ml, was as effective as insulin at a dose of 500 ng/ml in stimulating androstenedione and testosterone release. In addition to insulin, IGF-I/somatomedin C (50 ng/ml) stimulated androstenedione and testosterone release. Relaxin (1 microgram/ml) and multiplication-stimulating activity (50 ng/ml) did not stimulate androstenedione and testosterone release. These studies suggest that human ovarian stroma may be a target tissue for insulin and IGF-I, and that hyperinsulinemia may be an important factor contributing to ovarian hyperandrogenism.

On the origin of the elevated 17-hydroxyprogesterone levels after adrenal stimulation in hyperandrogenism.

Hyperandrogenic women appear to demonstrate an exaggerated 17-hydroxyprogesterone (17-HP) response to adrenal stimulation which is not due to the marked 21-hydroxylase deficiency of late-onset adrenal hyperplasia (LOAH). Furthermore, in hyperandrogenism the ovary also appears to secrete excessive amounts of 17-HP. It is not clear to what extent the elevated 17-HP levels after ACTH stimulation are due to extraadrenal production of the steroid. This investigation was undertaken to assess the adrenal contribution to the elevated 17-HP levels after ACTH stimulation observed in non-LOAH hyperandrogenism. One hundred and sixty consecutive unselected women with hirsutism and/or hyperandrogenic oligomenorrhea formed the clinical population. Excluded were 4 women with LOAH and all patients with hyperprolactinemia. For the purpose of investigating the relationship between adrenal response and clinical symptoms, hyperandrogenic patients were divided into 3 subgroups: hirsute only (n = 23), hirsute oligomenorrheic (n = 84), and oligomenorrheic only (n = 24). Subclassification for an additional 29 patients (18%) with hyperandrogenemia was not possible, since their symptomatology was not clearly stated in the record. However, these individuals were included in the patient group as a whole. Controls consisted of 21 healthy, regularly menstruating, nonhirsute female volunteers. Both patients and controls underwent acute adrenal stimulation with 1 mg ACTH-(1-24), and serum was obtained before and 30 min after ACTH administration. Hyperandrogenic patients had higher mean basal total testosterone (T), androstenedione (A), dehydroepiandrosterone sulfate (DHS), 17-HP, and LH/FSH levels, but not cortisol (F), compared to normal subjects (P less than 0.02). Oligomenorrheic only women had higher mean A and progesterone (P) levels than other hyperandrogenic patients (P less than 0.02). No correlation was noted between body mass index (BMI) and the levels of DHS, P, or A, while a weak positive association was noted between the BMI and the mean T (r = 0.31; P less than 0.002) and a weak negative correlation between the mean F and BMI (r = -0.21; P less than 0.05). The mean 17-HP level 30 min after ACTH administration (17-HP30) was significantly higher in hyperandrogenic women than in normal subjects whether analyzed in separate subgroups or together and was due to the higher basal 17-HP levels. Basal 17-HP correlated with the circulating levels of T, A, and P, steroids largely of ovarian origin. Alternatively, the net increment in 17-HP from 0-30 min after ACTH (delta 17-HP30) was not significantly higher in hyperandrogenic women than normal subjects and did not correlate with the basal levels of T, A, and P. Neither the basal level of 17-HP nor its response to ACTH correlated with circulating DHS levels.(ABSTRACT TRUNCATED AT 400 WORDS)

A pilot study of the human chorionic gonadotrophin test for ovarian hyperandrogenism.

A controlled clinical study was designed to investigate the value of human chorionic gonadotrophin (HCG) challenge as a test for functional ovarian hyperandrogenism. Dexamethasone administration was followed by 5000 IU HCG and blood samples for steroid hormone assay were obtained 0, 8, 16, and 24 h thereafter. Study subjects were normal women (n = 13); women with functional ovarian hyperandrogenism, defined by androgen excess, amenorrhoea and an increased 17-hydroxyprogesterone response to nafarelin (n = 6); and normal men (n = 4). The responses of 17-hydroxyprogesterone, androstenedione and testosterone to HCG in women with functional ovarian hyperandrogenism were significantly greater than in normal women. However, the 17-hydroxyprogesterone response to HCG in functional ovarian hyperandrogenism was significantly lower after HCG than after nafarelin. The oestradiol response was also significantly lower after HCG than nafarelin, although oestradiol concentration more than doubled in normal women as well as in women with functional ovarian hyperandrogenism. The responses to HCG confirm that functional ovarian hyperandrogenism abnormalities are luteinizing hormone (LH)-dependent. Therefore, the 17-hydroxyprogesterone response to HCG could represent a useful test for the diagnosis of ovarian hyperandrogenism. The lower 17-hydroxyprogesterone response to HCG than to nafarelin in functional ovarian hyperandrogenism suggests that a follicle-stimulating hormone (FSH)-responsive factor modulates thecal 17-hydroxyprogesterone secretion. The oestradiol response to HCG is consistent with HCG directly stimulating the oestradiol secretion by thecal cells.

Dexamethasone suppression test in the management of hyperandrogenized patients.

The authors evaluated 86 hyperandrogenized women with measurements of serum cortisol, dehydroepiandrosterone sulfate, testosterone, and dihydrotestosterone in pooled sera before and after a dexamethasone suppression test. According to strict criteria, 70 (81%) of 86 women demonstrated a major glucocorticoid-suppressible component to their hyperandrogenism. Endocrine therapy was dictated by the results of the dexamethasone suppression test. To assess the predictive value of this test, we evaluated the clinical responses of the subgroup of 55 women who received appropriate endocrine suppression therapy for 6 to 15 months. Of this subgroup, 38 were identified as having adrenal hyperandrogenism; 3 had ovarian hyperandrogenism; and 14 had mixed hyperandrogenism. Of the 55 patients, 49 received dexamethasone alone; 3 received dexamethasone plus Ovral (an oral contraceptive containing the synthetic progestogen norgestrel 0.5 mg and ethinyl estradiol 0.05 mg); and 3, all with ovarian hyperandrogenism, received depomedroxyprogesterone acetate (Depo-Provera). Clinical response was assessed in terms of improvement or no improvement in menstrual status, acne, and hirsutism. Of 29 patients with adrenal or mixed hyperandrogenism associated with abnormal menses, the menstrual status of 17 (59%) improved after dexamethasone therapy. Acne improved in 39 (100%) of 39 subjects. Hirsutism showed moderate to marked improvement in 40 (73%) of 55 women after 6 to 15 months of endocrine suppression therapy. These results indicate the endocrine suppression therapy, particularly with repeated low-dose dexamethasone, prescribed on the basis of a dexamethasone suppression test, is an effective means of managing hyperandrogenism.

Two hyperandrogenic adolescent girls with congenital portosystemic shunt.

UNLABELLED: We describe two adolescent girls with a congenital portosystemic shunt who exhibited hyperandrogenism in addition to insulin resistant hyperinsulinaemia. Case 1 was referred to our clinic to undergo a routine clinical work-up prior to tonsillectomy at 14 years of age. Mild liver dysfunction was identified and hypogenesis of the portal vein with a congenital portosystemic shunt diagnosed. Primary amenorrhoea and virilization were evident and an endocrinological evaluation revealed hyperandrogenism and insulin resistant hyperinsulinaemia. Case 2 was referred at 15 years of age because of cardiomegaly. Mild liver dysfunction and hyperbilirubinaemia led to a diagnosis of agenesis of the portal vein with a congenital portosystemic shunt. Virilization was evident and an endocrinological evaluation revealed hyperandrogenism and insulin resistant hyperinsulinaemia. The haemodynamics of these patients were similar to those of secondary portosystemic shunt due to liver cirrhosis, which is often associated with hyperinsulinaemia and/or non-insulin dependent diabetes mellitus. On the other hand, hyperandrogenism is associated with certain insulin-resistant conditions with hyperinsulinaemia, including the polycystic ovary syndrome (PCO). Hyperinsulinaemia is believed to cause hyperandrogenism in patients with PCO by stimulating androgen production in both the ovary and adrenal gland. Therefore, in congenital portosystemic shunts, hyperinsulinaemia is also thought to cause hyperandrogenism due to the same mechanism. CONCLUSION: A certain percentage of female patients with hyperandrogenism, likely including those with polycystic ovary syndrome may also have congenital portosystemic shunts. Our results indicate that serum levels of total bile acids and ammonia are prognostic indicators of this hepatic vascular anomaly.

Chronic hyperinsulinemia and the adrenal androgen response to acute corticotropin-(1-24) stimulation in hyperandrogenic women.

OBJECTIVE: Many women with androgen excess demonstrate elevated circulating insulin levels independent of obesity. In addition, in these women some investigators have demonstrated a negative correlation between the circulating levels of the adrenal androgens, dehydroepiandrosterone or dehydroepiandrosterone sulfate and insulin. The mechanism by which insulin decreases adrenal androgens is unclear. The objective of this study was to determine whether chronic hyperinsulinemia in hyperandrogenic women results in an alteration in the adrenocortical response to corticotropin, resulting in decreased androgen secretion. STUDY DESIGN: We studied seven hyperandrogenic women with severe chronic hyperinsulinemia and eight hyperandrogenic normoinsulinemic patients. Nine healthy women served as controls for the basal hormonal levels and the response to a 3-hour, 100 gm oral glucose tolerance test. In all subjects insulin and glucose were measured hourly during the oral glucose tolerance test and the baseline sample was assayed for total testosterone, dehydroepiandrosterone sulfate, dehydroepiandrosterone, androstenedione, sex hormone-binding globulin, and free testosterone. In hyperandrogenic women cortisol, dehydroepiandrosterone, and androstenedione were also measured, before and 60 minutes, after acute intravenous administration of 0.25 mg corticotropin (1-24). RESULTS: There was no difference in the response of cortisol, dehydroepiandrosterone, or androstenedione to corticotropin-(1-24) stimulation between normoinsulinemic and hyperinsulinemic hyperandrogenic patients. As defined, the hyperinsulinemic patients had higher basal and peak insulin levels and areas under the insulin response curve compared with the normoinsulinemic patients or controls. Total testosterone and dehydroepiandrosterone did not differ among study groups. As expected, hyperandrogenic patients demonstrated lower sex hormone-binding globulin activity and higher free testosterone, androstenedione, and dehydroepiandrosterone sulfate basal levels compared with controls. CONCLUSIONS: The results of this study do not support the hypothesis that chronic hyperinsulinemia in hyperandrogenic patients significantly inhibits the andrenocortical secretion of dehydroepiandrosterone or androstenedione in response to corticotropin stimulation or the basal circulating adrenal androgen levels. Additional studies, including a greater number of patients, may be needed to fully establish these conclusions.

Abnormalities in the serum insulin-like growth factor-1 axis in women with hyperandrogenism.

OBJECTIVE: To study the insulin-like growth factor-1 (IGF-1) axis in hirsute women. DESIGN: Controlled clinical study. SETTING: Tertiary care institutional hospital. PATIENT(S): Forty hirsute women and 17 women with normal menstrual cycles. INTERVENTION(S): Basal and ACTH-stimulated samples were obtained, and sampling was repeated 1 (gonadal stimulation) and 21 (gonadal suppression) days after a single 3.75-mg IM dose of triptorelin. Controls did not receive triptorelin for ethical reasons. MAIN OUTCOME MEASURE(S): Serum GH, IGF-1, IGF-binding protein-3 (IGFBP-3), insulin, glucose, total testosterone, sex hormone-binding globulin, E2, and gonadotropin levels. Basal and ACTH-stimulated steroid precursors were measured. RESULT(S): Patients with idiopathic hirsutism were identified by normal serum androgen levels (n=17). Those with functional ovarian hyperandrogenism (n=15) were identified by an increase in the serum testosterone level that normalized during gonadal suppression, whereas those with functional adrenal hyperandrogenism (n=8) were identified by an initial increase in the testosterone level that persisted during gonadal suppression. The adrenal hyperandrogenism group had increased IGF-1 levels compared with the control, idiopathic hirsutism, and ovarian hyperandrogenism groups. Patients with ovarian hyperandrogenism had normal TGF-1 concentrations, but their IGFBP-3 concentrations were lower than those of controls. No differences were observed in GH levels between any of the groups. These results persisted when the influence of age was corrected for. CONCLUSION(S): The IGF-1 axis appears to be involved in the pathogenesis of hyperandrogenism, especially in patients with adrenal hyperandrogenism, who have a clear increase in IGF-1 levels. Moreover, patients with ovarian hirsutism have decreased IGFBP-3 concentrations, which might enhance IGF-1 bioavailability.

Treatment of hirsutism, hyperandrogenism, oligomenorrhea, dyslipidemia, and hyperinsulinism in nonobese, adolescent girls: effect of flutamide.

Functional ovarian hyperandrogenism, a variant of polycystic ovary syndrome, is often associated with hyperinsulinism and dyslipidemia. The mechanisms interlinking this triad are poorly understood; both hyperandrogenism and hyperinsulinism have been proposed as factors involved in the pathogenesis of the dyslipidemia. Precocious pubarche (PP) in girls is a risk factor for subsequent anovulation, ovarian and adrenal hyperandrogenism, hyperinsulinism and dyslipidemia. Flutamide, a nonsteroidal antiandrogen, is known to be effective in reducing hirsutism in patients with ovarian hyperandrogenism. However, the effects of flutamide on the endocrine-metabolic correlates of hyperandrogenism are uncertain. We assessed the effects of low dose flutamide treatment (250 mg daily for 18 months) on hormonal and metabolic variables in 18 nonobese adolescent girls (age, 16.8 +/- 0.3 yr) with functional ovarian hyperandrogenism (diagnosis by GnRH agonist test) after PP. Flutamide treatment was accompanied by a marked decrease in the hirsutism score, free androgen index, and testosterone, androstenedione, and dehydroepiandrosterone levels and by an increase in sex hormone-binding globulin concentrations. However, there were no substantial changes in the pattern of menstrual cycles, gonadotropin, estradiol, or dehydroepiandrosterone sulfate concentrations, and there was no detectable effect on the 17-hydroxyprogesterone response to GnRH agonist. Serum triglycerides, total cholesterol, and low-density lipoprotein cholesterol levels decreased markedly during flutamide therapy, whereas high-density lipoprotein cholesterol, fasting glycemia/insulinemia, and the insulin response to a glucose load remained unchanged. Flutamide was well tolerated. In conclusion, low dose flutamide treatment was found to be an effective and safe approach to reduce hirsutism and circulating androgen, low-density lipoprotein cholesterol, and triglyceride levels in girls with functional ovarian hyperandrogenism after PP. However, flutamide failed to increase high-density lipoprotein cholesterol levels or decrease hyperinsulinemia, i.e. to affect two major risk factors for subsequent cardiovascular disease.

Growth hormone, insulin-like growth factor-I axis, and insulin secretion in hyperandrogenic adolescents.

OBJECTIVE: To assess GH and insulin-like growth factor I (IGF-I) axis variability in hyperandrogenic adolescents with different sources of androgen excess and their relationship with insulin resistance. DESIGN: Baseline IGF-I, insulin-like growth factor binding protein-1 (IGFBP-1), IGFBP-3, GH response to the exercise-propranolol test, and insulin responses to a standard oral glucose tolerance test were compared among patients with functional ovarian hyperandrogenism, hyperandrogenic nonfunctional ovarian hyperandrogenism patients, and age-matched controls. SETTING: Outpatient clinic in a medical center. PATIENTS: Twenty-one adolescents with ovarian (group A) and 17 with nonovarian (group B) hyperandrogenism, and 20 controls. RESULTS: Serum IGF-I and poststimulated GH levels were similar among groups, whereas serum IGFBP-3 levels were significantly lower in group A than in controls. Mean serum insulin levels were significantly higher in patients than in controls, whereas 24% of patients had abnormal insulin responses to glucose and/or insulin sensitivity indexes. Serum IGFBP-3 levels correlated negatively with the free androgen index (free androgen index = T/sex hormone-binding globulin [SHBG] x 100), whereas mean serum insulin levels correlated positively with the free androgen index and negatively with SHBG levels in all subjects. CONCLUSIONS: Hyperinsulinemia is common in hyperandrogenic adolescents and correlates with the degree of hyperandrogenism and not with the androgen source. Hyperinsulinemia and decreased IGFBP-3 levels may enhance IGF-I bioavailability, which in turn may both decrease SHBG levels and increase androgen production.

[Acne, hyperandrogenism and oral isotretinoin resistance. 23 cases. Therapeutic implications].

BACKGROUND: We earlier demonstrated that oral isotretinoin can be associated with hyperandrogenism in women with acne. The aim of this study was to evaluate the causal relationships of the different etiologies in case of unsuccessful treatment. PATIENTS AND METHODS: The study group included 120 patients with late-onset acne resistant to different treatment and signs of hyperandrogenism. A complete hormone work-up was obtained in all patients. There was a group of 23 patients who failed to respond to isotretinoin and 97 patients in the control group. Unsuccessful treatment was defined as persistance of grade 2 lesions after a mean cumulative dose of 166 mg/kg isotretinoin. RESULTS: In the non-responders to isotretinoin, hyperandrogenism was observed in 22 out of 23 cases: pituitary (n = 2), adrenal (n = 5), ovarian (n = 13), peripheral (n = 2). In the control group, hyperandrogenism was found in 89 out of 97 patients: pituitary (n = 6), adrenal (n = 45), ovarian (n = 33), peripheral (n = 5). The distribution of two etiologies, ovary and adrenal, demonstrated a significant difference between isotretinoin non-responders and controls, the former having a higher frequency of ovarian hyperandrogenism. DISCUSSION: These findings confirm that untreated hyperandrogenism, particularly ovarian hyperandrogenism, is a source of unsuccessful treatment with oral isotretinoin.

Hyperandrogenism, insulin resistance, and acanthosis nigricans syndrome: a common endocrinopathy with distinct pathophysiologic features.

The HAIR-AN syndrome that consists of hyperandrogenism (HA), insulin resistance (IR), and acanthosis nigricans (AN) is an underdiagnosed endocrinopathy, because hyperandrogenic women are not commonly screened for insulin resistance or acanthosis nigricans. The distinct pathophysiologic features of the HAIR-AN syndrome are discussed in detail. In this syndrome, the primary pathophysiologic derangements are the insulin resistance and the hyperandrogenism. The acanthosis nigricans is an epiphenomenon of these primary processes. In patients with the HAIR-AN syndrome, the degree of severity of the insulin resistance is positively correlated with the degree of severity of the hyperandrogenism. In patients with adequate pancreatic beta-islet cell reserve, insulin resistance results in a long-term increase in circulating insulin levels. The hyperinsulinemia probably directly stimulates ovarian androgen production. In turn, hyperandrogenism itself produces insulin resistance. This positive feedback loop between insulin resistance and hyperandrogenism propagates the disease, and increases its severity over time. The relationship between insulin resistance and hyperandrogenism may explain the hyperandrogenemia seen in the following disease processes: obesity, acromegaly, lipoatrophic diabetes, leprechaunism, and Kahn types A and B insulin resistance.

11 beta-hydroxylase deficiency in hyperandrogenism.

OBJECTIVE: to determine the 11-deoxycortisol (S) response and incidence of 11 beta-hydroxylase deficiency in hyperandrogenism. DESIGN: Hyperandrogenic women prospectively and consecutively underwent acute adrenal stimulation studies. SETTING: Tertiary institution. PATIENTS: Two hundred sixty women complaining of hirsutism and/or hyperandrogenic oligomenorrhea were studied, excluding five unrelated families (1.9% of total) suffering from 21-hydroxylase deficient late-onset adrenal hyperplasia. Forty-one healthy premenopausal eumenorrheic women served as controls. MAIN OUTCOME MEASURES: Only two unrelated women (0.8%) had a poststimulation or net increment S level value greater than or equal to threefold the upper 95th percentile of controls and were presumed to suffer from 11 beta-hydroxylase deficient late-onset adrenal hyperplasia. One hundred nine (42%) of hyperandrogenic women had at least one S value above the 95th percentile of controls. These women also demonstrated higher basal (F0) and stimulated cortisol levels, but a similar increment compared with controls. RESULTS: Patients with high S measures had higher testosterone, dehydroepiandrosterone sulfate, and androstenedione levels, but similar luteinizing hormone/follicle-stimulating hormone ratios, than hyperandrogenic cohorts with no abnormal S measures. Basal values of S (S0), F0, or S0/F0 were not useful to predict an abnormal S response to stimulation. CONCLUSIONS: Although adrenocortical hyperactivity was present in 42% of our hyperandrogenic patients, only 0.8% were presumed to suffer from 11 beta-hydroxylase deficient late-onset adrenal hyperplasia. A systemic search for this deficiency in hyperandrogenism is probably unwarranted.
