Epidemiology, diagnosis and management of hirsutism: a consensus statement by the Androgen Excess and Polycystic Ovary Syndrome Society

BACKGROUND Hirsutism, defined by the presence of excessive terminal hair in androgen-sensitive areas of the female body, is one of the most common disorders in women during reproductive age. METHODS We conducted a systematic review and critical assessment of the available evidence pertaining to the epidemiology, pathophysiology, diagnosis and management of hirsutism. RESULTS The prevalence of hirsutism is ~10% in most populations, with the important exception of Far-East Asian women who present hirsutism less frequently. Although usually caused by relatively benign functional conditions, with the polycystic ovary syndrome leading the list of the most frequent etiologies, hirsutism may be the presenting symptom of a life-threatening tumor requiring immediate intervention. CONCLUSIONS Following evidence-based diagnostic and treatment strategies that address not only the amelioration of hirsutism but also the treatment of the underlying etiology is essential for the proper management of affected women, especially considering that hirsutism is, in most cases, a chronic disorder needing long-term follow-up. Accordingly, we provide evidence-based guidelines for the etiological diagnosis and for the management of this frequent medical complaint.

The polycystic ovary syndrome: a position statement from the European Society of Endocrinology.

Polycystic ovary syndrome (PCOS) is the most common ovarian disorder associated with androgen excess in women, which justifies the growing interest of endocrinologists. Great efforts have been made in the last 2 decades to define the syndrome. The presence of three different definitions for the diagnosis of PCOS reflects the phenotypic heterogeneity of the syndrome. Major criteria are required for the diagnosis, which in turn identifies different phenotypes according to the combination of different criteria. In addition, the relevant impact of metabolic issues, specifically insulin resistance and obesity, on the pathogenesis of PCOS, and the susceptibility to develop earlier than expected glucose intolerance states, including type 2 diabetes, has supported the notion that these aspects should be considered when defining the PCOS phenotype and planning potential therapeutic strategies in an affected subject. This paper offers a critical endocrine and European perspective on the debate on the definition of PCOS and summarises all major aspects related to aetiological factors, including early life events, potentially involved in the development of the disorder. Diagnostic tools of PCOS are also discussed, with emphasis on the laboratory evaluation of androgens and other potential biomarkers of ovarian and metabolic dysfunctions. We have also paid specific attention to the role of obesity, sleep disorders and neuropsychological aspects of PCOS and on the relevant pathogenetic aspects of cardiovascular risk factors. In addition, we have discussed how to target treatment choices based according to the phenotype and individual patients needs. Finally, we have suggested potential areas of translational and clinical research for the future with specific emphasis on hormonal and metabolic aspects of PCOS.

Sheehan's Syndrome

Sheehans syndrome occurs as a result of ischemic pituitary necrosis due to severe postpartum hemorrhage. It may be rarely seen without massive bleeding or after normal delivery. Improvement in obstetric care and availability of rapid blood transfusion coincided with a remarkable reduction in the frequency of Sheehans syndrome particularly in western society. But it has recently been reported more often from well-developed countries. It is one of the most common causes of hypopituitarism in underdeveloped or developing countries. Enlargement of pituitary gland, small sella size, disseminated intravascular coagulation and autoimmunity have been suggested to play a role in the pathogenesis of Sheehans syndrome in women who suffer from severe postpartum hemorrhage. The patients may seek medical advice because of various presentations ranging from non-specific symptoms to coma and the clinical manifestation may change from one patient to another. Failure of postpartum lactation and failure to resume menses after delivery are the most common presenting symptoms. Although a small percentage of patients with Sheehans syndrome may cause abrupt onset severe hypopituitarism immediately after delivery, most patients have a mild disease and go undiagnosed and untreated for a long time. It may result in partial or panhypopituitarism and GH is one of the hormones lost earliest. The great majority of the patients has empty sella on CT or MRI. Lymphocytic hypophysitis should be kept in mind in differential diagnosis. In this review, the old and recent data regarding Sheehans syndrome are presented.

Physiological-dose steroid therapy in sepsis [ISRCTN36253388].

IntroductionThe aim of the study was to assess the prognostic importance of basal cortisol concentrations and cortisol response to corticotropin, and to determine the effects of physiological dose steroid therapy on mortality in patients with sepsis.MethodsBasal cortisol level and corticotropin stimulation test were performed within 24 hours in all patients. One group (20 patients) received standard therapy for sepsis and physiological-dose steroid therapy for 10 days; the other group (20 patients) received only standard therapy for sepsis. Basal cortisol level was measured on the 14th day in patients who recovered. The outcome of sepsis was compared.ResultsOnly Sequential Organ Failure Assessment (SOFA) score was found related to mortality, independent from other factors in multivariate analysis. No significant difference was found between the changes in the percentage of SOFA scores of the steroid therapy group and the standard therapy group in survivors, nor between the groups in basal and peak cortisol levels, cortisol response to corticotropin test and mortality. The mortality rates among patients with occult adrenal insufficiencies were 40% in the steroid therapy group and 55.6% in the standard therapy group.DiscussionThere was a trend towards a decrease in the mortality rates of the patients with sepsis who received physiological-dose steroid therapy. In the advancing process from sepsis to septic shock, adrenal insufficiency was not frequent as supposed. There was a trend (that did not reach significance) towards a decrease in the mortality rates of the patients with sepsis who received physiological-dose steroid therapy.

The hypothalamo–pituitary–adrenal axis in chronic fatigue syndrome and fibromyalgia syndrome

The hypothalamo–pituitary–adrenal (HPA) axis plays a major role in the regulation of responses to stress. Human stress-related disorders such as chronic fatigue syndrome (CFS), fibromyalgia syndrome (FMS), chronic pelvic pain and post-traumatic stress disorder are characterized by alterations in HPA axis activity. However, the role of the HPA axis alterations in these stress-related disorders is not clear. Most studies have shown that the HPA axis is underactive in the stress-related disorders, but contradictory results have also been reported, which may be due to the patients selected for the study, the methods used for the investigation of the HPA axis, the stage of the syndrome when the tests have been done and the interpretation of the results. There is no structural abnormality in the endocrine organs which comprise the HPA axis, thus it seems that hypocortisolemia found in the patients with stress-related disorder is functional. It may be also an adaptive response of the body to chronic stress. In this review, tests used in the assessment of HPA axis function and the HPA axis alterations found in CFS and FMS are discussed in detail.

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.
