Hormonal Profile in Women with Polycystic Ovarian Syndrome with or without Type 1 Diabetes Mellitus

Anti-Müllerian hormone (AMH) levels are increased in polycystic ovarian syndrome (PCOS), but it is not known whether other forms of hyperandrogenism, such as PCOS observed in women with type 1 diabetes mellitus (DM1), are also associated with elevated AMH levels. Our objective was to compare AMH and steroid levels in women with PCOS with and without DM1. We compared the clinical, hormonal, and ultrasonographic characteristics of 17 women with PCOS and DM1 (DM1+PCOS), 20 women with PCOS without DM1 (PCOS), and 35 normal women (control) in a cross-sectional study. The Ferriman-Gallwey score, serum testosterone, free androgen index, 17OH-progesterone, and ovarian volume were elevated in both groups of PCOS women compared with controls. Serum androstenedione, LH/FSH ratio, and follicle number, however, were higher and SHBG was lower in PCOS compared with DM1+PCOS and controls. AMH levels were higher in PCOS (76.0 +/- 36.3 pmol/liter) than in DM1+PCOS (18.8 +/- 7.4 pmol/liter) and controls (13.9 +/- 8.3 pmol/liter). AMH levels correlated with follicle number in the three groups. Serum AMH/follicle number ratio was higher in PCOS than in DM1+PCOS and controls. Women with DM1+PCOS have normal levels of AMH, inhibin B, estradiol, SHBG, and LH/FSH, suggesting that the pathophysiology of hyperandrogenism in PCOS patients with DM1 appears to be different from that in PCOS without DM1. However, hirsutism score and androgen levels were similar in both groups of women with PCOS. We postulate that insulin treatment acts as a co-gonadotropin increasing follicle recruitment, hence not increasing AMH levels.

In vitro responsiveness of human post-menopausal myometrium to endothelin-1 and ovarian steroids

It has been shown in vitro that endothelin 1 (ET1) differentially affects the human myometrial contractility according to the hormonal profile of women. Our purpose was to test the hypothesis that ovarian steroids influence the ET1 induced myometrial contractility. We performed three types of experiments. Myometrial tissues were exposed to 17beta-oestradiol (E), progesterone (P), E plus P (E+P) in concentrations 10(-10)M, 10(-8)M, 10(-7)M, 10(-6)M and 10(-4)M (Type I), ET1 in concentrations 10(-10)M, 10(-9)M, 10(-8)M, 10(-7)M and 10(-6)M (Type II) and E+ET1, P+ET1 and E+P+ET1 in concentrations ranging from 10(-10)M to 10(-6)M (Type III). Tissue exposure to E, P and E+P did not significantly alter the pattern of spontaneous myometrial motility. ET1 (10(-6)M) induced a sustained long-lasting contraction, the initial part of which lasted 34 +/- 4 min, elevating the initial baseline by 190 +/- 20%. This was followed by ripples of gradually increasing amplitude with no regular contractions up to the end of the period of observation (120 min). Addition of P or E+P to ET1 markedly restricted (p<0.05) the elevation of initial baseline (P+ET1: 68 +/- 8%, P+E+ET1: 67 +/- 8%), and significantly shortened (p<0.01) the duration of the alterations (P+ET1: 21 +/- 3 min, P+E+ET1: 26 +/- 3 min). These results demonstrate the lack of any significant effect of E and P or their combinations on the pattern of spontaneous myometrial motility in post-menopausal women. However, P alone or in combination with E exerted an inhibitory action on ET1 -induced contractility on human post-menopausal myometrium. The physiological significance of these findings remains to be clarified.

Hormonal profile of women with self-reported symptoms of oligomenorrhea and/or hirsutism: Northern Finland birth cohort 1966 study.

The hormonal profiles of nested female patients (n = 500) with self-reported symptoms typical of polycystic ovary syndrome (PCOS), oligomenorrhea, and/or hirsutism and their randomly selected controls (n = 1026) at the age of 31 yr were analyzed in a general population-based Northern Finland birth cohort 1966 to find out whether the symptomatic women also have the endocrine characteristics of PCOS and could be detected in a general population using simple questions. Higher medians of serum testosterone (T) (2.10 vs. 1.90 nmol/liter, P < 0.001), LH (5.40 vs. 4.85 U/liter, P = 0.005), insulin (53.8 vs. 51.66 pmol/liter, P = 0.040), and free androgen index (FAI) (4.01 vs. 3.03, P < 0.001) and lower glucose/insulin ratio (91.1 x 10(8) vs. 94.9 x 10(8), P = 0.048) and SHBG (52.4 vs. 60.7 nmol/liter, P < 0.001) were observed among the cases, but no difference was observed in cortisol and glucose levels between the cases and controls. Of all the women in the cohort, 10.2% reported only oligomenorrhea and had biochemical findings similar to the whole case group. Those who reported only hirsutism (10.4%) were in between the case and control groups according to biochemical findings. The subjects who reported both oligomenorrhea and hirsutism (3.4%) had the highest T, LH, FAI, insulin, and glucose and the lowest SHBG and glucose/insulin ratio, compared with the case group and the groups with either symptom only indicating a dose-response manner in typical endocrine profile of PCOS by adding up symptoms. The levels of T and FAI were higher and SHBG lower in groups with overweight or obesity both at 14 and 31 yr, compared with groups with normal weight at 14 yr and overweight or obesity at 31 yr. In the group with normal weight at 14 and 31 yr and the group with overweight or obesity at 14 yr but normal weight at 31 yr, the levels of T and FAI were lowest and SHBG highest. T and FAI were higher and SHBG lower among the cases than the controls in groups stratified by weight development from adolescence to adulthood. In conclusion, this longitudinal study of a large, stable population indicates that women with self-reported symptoms of hirsutism and/or oligomenorrhea show endocrine characteristics of PCOS and can be detected in a general population using simple questions. These symptoms are markers of the underlying metabolic alterations possibly associated with increased health risks in later life.

Asthma and sex hormones.

A chronic in ammatory state of the airways is considered the hallmark of asthma (1). However, the incidence, severity, and prognosis of asthma can be affected by a number of factors, including the patient's sex and age. The sex of the fetus seems to in uence the development of the respiratory apparatus. In fact, between weeks 28 and 40 of gestation, the lungs are in a more advanced state in females than in males (2), a fact which could explain, at least in part, the higher incidence of respiratory distress in male infants (3). Clinical observations and epidemiologic studies agree that childhood asthma is more frequent in boys than in girls (4). Moreover, in some children, usually boys, asthmatic symptoms that started in infancy disappear around puberty (5), while many girls have the disease only during adolescence (6). Age has been implicated in the severity of asthma. Asthma beginning during adulthood is generally more severe than childhood-onset asthma (7). Asthma that starts around the menopause or in old age is generally quite severe (5). According to two recent epidemiologic investigations, the patient's sex and age affect the hospitalization rate for asthma (8, 9), which is a marker of severity. In the ®rst study (a retrospective study of 33 269 patients), the admission rate of boys in the 0±10-year age group was almost twice that of girls. In the next decade, sex differences in the hospitalization rate were irrelevant, although there was a small, but signi®cant prevalence of females. At all ages above 20 years, hospital admission rates were higher in women than men, with a female/ male ratio ranging from 3:1 in subjects aged 20±50 years to 2.5:1 in those over 50 years of age (8). Similar data were reported by Elliasson (9). Both studies found a relationship between the age and sex of the patient and the severity of the asthma attack as indicated by duration of hospitalization. In fact, the duration of hospitalization increased with age in both sexes; moreover, hospital stays were longer in women over 30 years of age than in men of the same age (8, 9). Abbreviations.

The hormonal profile of women with acne and polycystic ovaries

Most women with acne are found to have polycystic ovaries on high resolution pelvic ultrasonography, but most of these women do not manifest the other classical clinical characteristics of the polycystic ovary syndrome. We have compared the endocrinological profile of women with acne who were found to have polycystic ovaries with that of women with polycystic ovaries who presented to an endocrine clinic with hirsutes or non-dermatological manifestations of the polycystic-ovary syndrome. The group of women with acne had normal serum hormonal concentrations. Unlike other women with polycystic ovaries, they did not have significantly elevated serum concentrations of luteinizing hormone or testosterone. By clinical and endocrinological criteria, patients with acne who have polycystic ovaries appear to be a distinct sub-population of women with polycystic ovaries.

Subtle abnormalities in follicular development and hormonal profile in women with unexplained infertility

A prospective study of six unselected couples diagnosed as having unexplained infertility was done. In three of six patients, subtle abnormalities in follicular development were detected. In the first case poor follicular growth was observed. There was a premature small rise of luteinizing hormone (LH) with subsequent low levels of estradiol (E 2 ) in the late follicular phase and unusual wide LH peak. This was followed by low progesterone levels in the luteal phase. In the second case follicular growth was abrupted by premature LH surge. This surge was triggered by early rise of E 2 level while the follicle was still small in size. In the third case luteinized unruptured follicle syndrome was diagnosed, on ultrasound examination. All of the abnormalities were repetitive.
