RESUMO

Premature ovarian insufficiency (POI), previously known as premature ovarian failure or premature menopause, is defined as loss of ovarian function before the age of 40 years. The risk of POI before the age of 40 is 1%. Clinical symptoms develop as a result of estrogen deficiency and may include amenorrhea, oligomenorrhea, vasomotor instability (hot flushes, night sweats), sleep disturbances, vulvovaginal atrophy, altered urinary frequency, dyspareunia, low libido, and lack of energy. Most causes of POI remain undefined, however, it is estimated that anywhere from 4-30% of cases are autoimmune in origin. As the ovaries are a common target for autoimmune attacks, an autoimmune etiology of POI should always be considered, especially in the presence of anti-oocyte antibodies (AOAs), autoimmune diseases, or lymphocytic oophoritis in biopsy. POI can occur in isolation, but is often associated with other autoimmune conditions. Concordant thyroid disorders such as hypothyroidism, Hashimoto thyroiditis, and Grave's disease are most commonly seen. Adrenal autoimmune disorders are the second most common disorders associated with POI. Among women with diabetes mellitus, POI develops in roughly 2.5%. Additionally, autoimmune-related POI can also present as part of autoimmune polyglandular syndrome (APS), a condition in which autoimmune activity causes specific endocrine organ damage. In its most common presentation (type-3), APS is associated with Hashomoto's type thyroid antibodies and has a prevalence of 10-40%. 21OH-Antibodies in Addison's disease (AD) can develop in association to APS-2.

RESUMO

Congenital anomalies of the female reproductive tract that present with primary amenorrhea involve Müllerian aplasia, also known as Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS), and cervical and vaginal anomalies that completely obstruct the reproductive tract. Karyotype abnormalities do not exclude the diagnosis of MRKHS. Familial cases of Müllerian anomalies and associated malformations of the urinary and skeletal systems strongly suggest a complex genetic etiology, but so far, the molecular mechanism in the vast majority of cases remains unknown. Primary amenorrhea may also be the first presentation of complete androgen insensitivity syndrome, steroid 5α-reductase type 2 deficiency, 17ß-hydroxysteroid dehydrogenase type 3 deficiency, and Leydig cells hypoplasia type 1; therefore, these disorders should be considered in the differential diagnosis of the congenital absence of the uterus and vagina. The molecular diagnosis in the majority of these cases can be established.

RESUMO

Primary ovarian insufficiency (POI) is characterized by amenorrhea and loss or dysfunction of ovarian follicles prior to the age of 40. POI has been associated with autosomal recessive mutations in genes involving hormonal signaling and folliculogenesis, however, the genetic etiology of POI most often remains unknown. Here we report MRPS22 homozygous missense variants c.404G>A (p.R135Q) and c.605G>A (p.R202H) identified in four females from two independent consanguineous families as a novel genetic cause of POI in adolescents. Both missense mutations identified in MRPS22 are rare, occurred in highly evolutionarily conserved residues, and are predicted to be deleterious to protein function. In contrast to prior reports of mutations in MRPS22 associated with severe mitochondrial disease, the POI phenotype is far less severe. Consistent with this genotype-phenotype correlation, mitochondrial defects in oxidative phosphorylation or rRNA levels were not detected in fibroblasts derived from the POI patients, suggesting a non-bioenergetic or tissue-specific mitochondrial defect. Furthermore, we demonstrate in a Drosophila model that mRpS22 deficiency specifically in somatic cells of the ovary had no effect on fertility, whereas flies with mRpS22 deficiency specifically in germ cells were infertile and agametic, demonstrating a cell autonomous requirement for mRpS22 in germ cell development. These findings collectively identify that MRPS22, a component of the small mitochondrial ribosome subunit, is critical for ovarian development and may therefore provide insight into the pathophysiology and treatment of ovarian dysfunction.

RESUMO

OBJECTIVE: To characterize the clinical features of a female patient with isolated follicle-stimulating hormone (FSH) deficiency and to investigate the underlying mechanisms of FSH inactivation. METHODS: The proband was a 29-year-old woman with primary amenorrhea, impaired pubertal development, and infertility. Subsequently, reproductive endocrine was screened. DNA sequencing was conducted for the identification of FSHß mutation. RT-PCR, western blots, in vitro immunometric assay, and bioassay were performed to confirm the impact of the mutation on FSH expression and biological activity. Molecular model consisting of FSHα and mutant FSHß subunit was built for the structural analysis of FSH protein. RESULTS: The evaluation of reproductive endocrine revealed undetectable basal and GnRH-stimulated serum FSH. Sequencing of the FSHß gene identified a homozygous nonsense mutation at codon 97 (Arg97X). RT-PCR and western blot analysis revealed the mutation Arg97X did not affect FSHß mRNA and protein expression. But in vitro immunometric assay and bioassay demonstrated the production of normal bioactive FSH protein was disturbed by the mutation Arg97X. Structural analysis showed the surface structure of the resulting mutant FSH presented with lock-and-key, mosaic binding pattern, while the native structure was an encircling binding mode. CONCLUSION: The mutation Arg97X could disturb structural stability of the resulting FSH protein consisting of FSHα and mutant FSHß subunit, which may lead to FSH deficiency.

RESUMO

The aim of the present study was to determine the frequency and nature of chromosomal abnormalities involved in patients with the clinical spectrum of ambiguous genitalia (AG), amenorrhea, and Turner phenotype, in order to compare them with those reported elsewhere. The study was conducted in the Cytogenetic Department of Pasteur Institute of Morocco, and it reports on the patients who were recruited between 1996 and 2016. Cytogenetic analysis was performed according to the standard method. Among 1,415 patients, chromosomal abnormalities were identified in 7.13% (48/673) of patients with AG, 17.39% (28/161) of patients with primary amenorrhea (PA), 4% (1/25) of patients with secondary amenorrhea, and 23.20% (129/556) of patients with Turner phenotype. However, Turner syndrome was diagnosed in 0.89% (6/673) of patients with AG, 10.56% (17/161) of patients with PA, and 19.78% (110/556) of patients with Turner phenotype. In addition, Klinefelter syndrome and mixed gonadal dysgenesis were confirmed in 2.97% and 1.93% of patients, respectively, with AG, while, chimerism, trisomy 8, and trisomy 13 were confirmed only in 0.15% each. Trisomy 21 was confirmed in patients with AG and Turner phenotype (0.15% and 0.36%, respectively). Moreover, 5.60% (9/161) of patients with PA have been diagnosed as having sex reversal. Thus, the frequency of chromosomal abnormalities observed in Moroccan patients with PA is comparable to that reported in Tunisia, Turkey, Iran, and Hong Kong. However, the frequency is significantly less than that identified in India, Malaysia, Italy, and Romania.

RESUMO

OBJECTIVE: To establish reference ranges for uterine vein (UtV) diameters in non-pregnant women with normal pelvic organs. METHODS: This was a prospective study of all women attending the general gynecological clinic of a university teaching hospital in the UK, between August 2015 and December 2016. All women aged ≥ 18 years underwent a transvaginal ultrasound examination in accordance with the study protocol. In women with normal pelvic organs, the largest trunk of the uterine venous plexus was identified in the transverse plane on each side. The maximum anteroposterior vessel diameter was measured by placing the calipers on the inner walls of the vein, and the mean of three measurements was used as the representative value. Inter- and intraobserver variability was assessed in a subgroup of 30 women. Maximum UtV diameter was compared between right and left UtVs and between pre- and postmenopausal women. Factors associated with UtV diameter were assessed and reference ranges were constructed. RESULTS: Of 1500 women examined, 486 (32%) had normal pelvic organs on ultrasound scan and were included in the final analysis. In all women, the uterine venous trunk was clearly visualized and there was no significant difference between the maximum median left and right UtV diameters (P = 0.37). UtV diameters were generally lower in postmenopausal, compared with premenopausal, women, with the difference being statistically significant for the right UtV and the average of left and right UtVs. There was a gradual increase in UtV diameter with advancing age, with a peak observed in women aged 41-50 years and decreasing values in older age groups. Univariable analysis showed that parity, menopausal status and age were associated significantly with UtV diameters (P < 0.01). On multivariable analysis, only higher parity was significantly associated with increasing venous size in both pre- and postmenopausal women. Reference ranges were constructed separately for nulliparous and parous premenopausal women aged between 18 and 45 years. CONCLUSION: UtVs can be identified and measured consistently in all women with normal pelvic organs using transvaginal ultrasound. Parity was the main factor influencing the maximum mean UtV diameter, which had to be taken into account when constructing reference ranges. Copyright © 2019 ISUOG.

RESUMO

BACKGROUND: Functional hypothalamic amenorrhea (FHA) is a form of chronic anovulation not due to identifiable organic causes and with adverse health consequences. The identification of women with this disorder or the precocious identification of women at risk is based on the knowledge of lifestyle risk factors or behaviors such as stress, weight loss, and excessive physical exercise that are known to negatively impact gonadal axis activity. METHODS: In this overview, we described the most common forms of FHA, in particular stress-induced amenorrhea and overtraining-induced amenorrhea. In addition, although its mechanisms can differ from those involved in FHA, we reviewed the available literature on drug-induced amenorrhea, highlighting the clear connection between this condition and psychoactive drugs such as antipsychotics, antidepressants and anti-epilectics thus raising concern about the role that the abuse of substances such as opioids or alcohol can possibly have on the growing unexplained infertility of the female population.

RESUMO

BACKGROUND: Endocrine abnormalities are well-recognized consequences of intracranial pathology such as pituitary tumours. Less commonly, hydrocephalus may lead to dysfunction of the endocrine system, presenting as amenorrhoea or precocious puberty. We present a case report and literature review of hydrocephalus causing endocrine abnormalities including reversible infertility. CASE DESCRIPTION: A 34 year-old female presented with amenorrhoea and infertility. MRI showed a third ventricular mass and hydrocephalus. The amenorrhoea resolved within weeks of endoscopic third ventriculostomy and tumour biopsy; pregnancy ensued within 6 months. Thirty-two cases of hydrocephalus-related amenorrhoea were reported between 1915 and 2007. All patients who underwent modern hydrocephalus treatment experienced partial or complete resolution of endocrine dysfunction. Successful pregnancy was reported in three patients, as in our case presentation. While mechanisms of dysfunction have not been completely elucidated, studies point toward loss of GnRH pulsatility due to compression of the medio-basal hypothalamic structures. CONCLUSION: Hydrocephalus can cause endocrine dysfunction, including amenorrhoea, which may reverse with CSF diversion. Therefore, cranial imaging is an important component in the evaluation of such endocrine abnormalities.

RESUMO

Primary ovarian insufficiency (POI) is characterized by a loss of ovarian function before the age of 40 and account for one major cause of female infertility. POI relevance is continuously growing because of the increasing number of women desiring conception beyond 30 years of age, when POI prevalence is >1%. POI is highly heterogeneous and can present with ovarian dysgenesis and primary amenorrhea, or with secondary amenorrhea, and it can be associated with other congenital or acquired abnormalities. In most cases POI remains classified as idiopathic. However, the age of menopause is an inheritable trait and POI has a strong genetic component. This is confirmed by the existence of several candidate genes, experimental and natural models. The variable expressivity of POI defect may indicate that, this disease may frequently be considered as a multifactorial or oligogenic defect. The most common genetic contributors to POI are the X chromosome-linked defects. Here, we review the principal X-linked and autosomal genes involved in syndromic and non-syndromic forms of POI with the expectation that this list will soon be upgraded, thus allowing the possibility to predict the risk of an early age at menopause in families with POI.

RESUMO

OBJECTIVE: 17α-hydroxylase/17, 20-lyase deficiency (17OHD) is caused by mutations in the cytochrome P450 17A1 (CYP17A1) gene. To better understand 17OHD, a rare disease, we described the clinical features and performed CYP17A1 gene analysis in 8 affected Chinese patients. METHODS: Patients with complete (7/8) or partial (1/8) 17OHD were derived from 6 families. The diagnosis was established according to their clinical, biochemical, hormonal, and radiological characteristics. Long-term follow-up of some patients was also designed. RESULTS: Patients with 17OHD suffered from varying degrees of hypokalemia and hypertension. Symptoms in female patients with partial 17OHD manifested as secondary amenorrhea, recurrent ovarian cysts, elevated estradiol level, and lower follicle-stimulating hormone and luteinizing hormone levels; primary amenorrhea was typical in patients with complete 17OHD. Adrenal masses and decreased bone mineral density (BMD) were discovered in 2 patients, respectively. During long-term follow-up, 4 patients developed low BMD, while 3 individuals underwent respiratory infections and recurrent urinary tract infections. CYP17A1 gene analysis revealed 7 different kinds of mutation, including 1 novel mutation, L266V. CONCLUSION: The clinical characteristics of partial 17OHD were different from those of complete 17OHD. Low BMD and infections were common in patients with 17OHD on long-term steroid treatment. Seven mutations were identified in the CYP17A1 gene, and 1 was novel. ABBREVIATIONS: ACTH = adrenocorticotropic hormone BMD = bone mineral density CAH = congenital adrenal hyperplasia CT = computed tomography DEXA = dual-energy X-ray absorptiometry DEX = dexamethasone 17OHD = 17α-hydroxylase/17, 20-lyase deficiency.

RESUMO

We examined 11 women aged 19-26 years (mean age 22.5±3.5 years) with secondary amenorrhea complaining frequent urination over 1.5 years and repeatedly, but unsuccessful treated for overactive bladder and chronic cystitis. The rare cause of sustained urination disorders in young female patients of reproductive age was established: development of secondary amenorrhea caused by weight loss ("cosmetic" amenorrhea) with subsequent estrogene deficit and urogenital atrophy. Morphological examination of the bladder mucosa, an important clue to the diagnosis, helps to identify the true cause of dysuria, urogenital atrophy of the bladder mucosa, in secondary ("cosmetic") amenorrhea, and determine future course of etiopathogenic treatment of sustained dysuria in young women. The treatment is often effective in case of proper and timely diagnosis and the absence of irreversible changes.

RESUMO

Osteoporosis (OP) is a major public health concern that affects millions of women around the world. For many years, OP are among the most common diseases occurring inthe elderly. However, certain parts in the age structure of the disease are persons younger. The rising prevalence of OP is huge damage to human health due to an increase in morbidity and mortality associated with fractures. In this article are discussed OP risk factors, the most frequently detected in young women, knowledge of which will enable patients and training activities on preventing the development of OP.

RESUMO

Some features of the chromosome apparatus status were studied in 25 adolescent girls, aged 14-18, with secondary amenorrhea and in 29 girls of the same age with a regular menstrual cycle. Materials for cytogenetic analysis were preparations of chromosomes at the stage of metaphase obtained from the culture of the peripheral blood lymphocytes. The technique of the culture preparation was carried out according to the standard method. 2225 metaphase plates were analyzed in girls with secondary amenorrhea, and 2603 plates were tested in their healthy age-mates. An increased total level of chromosomal aberrations and a rise in the frequency of disorders in the chromatid, chromosome and genome types of peripheral blood lymphocytes have been registered in the examined persons as compared with their healthy age-mates. We have shown, that polyploid cell registered in 15 times oftener in adolescent girls with SA as compared with healthy girls. It can be assumed that some marked changes in the frequency of chromosomal aberrations in patients with secondary amenorrhea and in their healthy age-mates may arise both as a result of exposure to the multiple environmental factors and disorders of rather complicated processes of DNA damages reparation.

RESUMO

BACKGROUND: Functional hypothalamic amenorrhea (FHA) refers to a functional menstrual disorder with various causes and presentations. Recovery of menstrual cyclicity is common in long-term follow-up but the affecting factors remain unknown. AIM: To explore factors affecting the menstrual resumption and to evaluate the pituitary response to gonadotropin-releasing hormone (GnRH) in FHA. MATERIALS AND METHODS: Thirty cases with FHA were recruited. All subjects were put on continuous 1 mg/day estradiol valerate orally and followed up monthly. Recovery was defined as the occurrence of at least three consecutive regular cycles. Responder referred to those who recovered within two years of therapy. Gonadotropin response to the 50 µg GnRH challenge was tested every three months. RESULTS: Nineteen (63.3%) subjects recovered with a mean time to recovery of 26.8 months. Time to recovery was negatively correlated with body mass index (BMI) before and by amenorrhea. Twentyone cases had undertaken therapy for more than two years and 10 of them recovered. BMI before and by amenorrhea were negatively correlated with the recovery. Significant increase of serum luteinizing hormone (LH) and LH response to GnRH were noted after recovery. CONCLUSIONS: Menstrual resumption was common in FHA undertaking estrogen replacement therapy (ERT). The likelihood of recovery was affected by their BMI before and by amenorrhea but not by the weight gain during therapy. Low serum LH and attenuated LH response to GnRH were the main features of pituitary deficiency in FHA. The menstrual resumption in FHA was accompanied by the recovery of serum LH and the LH response to GnRH.

RESUMO

Obesity has a deteriorating impact on women with PCOS, although prevalence and the impact of specific traits of PCOS remain inconstant in different populations. Therefore, the aim of this study was to explore the differences in clinical, hormonal and metabolic features between obese and nonobese Croatian women diagnosed as having PCOS according to Rotterdam consensus criteria. The study included 74 obese and 208 nonobese women with PCOS. Clinical, biochemical and metabolic variables were compared among those PCOS subgroups. Obese subjects with PCOS had a higher risk of developing oligo-amenorrhea (OR 3.7; 95% CI, 1.1-12.5) and lower risk for developing hirsutism and acne (OR 0.2; 95% CI, 0.1-0.3 and OR 0.8; 95% CI 0.5-1.4, respectively). Obese PCOS subjects also had a higher risk of developing hyperandrogenemia (OR 2.5; CI 95% 0.9-6.7), insulin resistance (OR 4.5; CI 95%, 2.6-7.9), hypercholesterolemia (OR 5.0, CI 95% 2.5-10.2), hypertriglyceridemia (OR 5.2; 95% CI, 2.9-9.2) as well as elevated serum CRP levels (OR 4.1; 95% CI 1.4-12.2) compared to nonobese PCOS women. In conclusion, nonobese Croatian women with PCOS are more inclined to cosmetic problems associated with PCOS then metabolic ones. This is the first study to report the impact of obesity on acne and irregular menses as a study outcome. Obesity deteriorates menstrual regularity, insulin sensitivity and lipid profile in Croatian women with PCOS; therefore one of the fundamental treatment strategies of PCOS should be obesity prevention.

RESUMO

BACKGROUND: Glucose-induced kinetics of bone marrow-derived stem cells in healthy females is presently unknown. The objectives of this study were to determine whether circulating levels of CD133(+), CD34(+) and CD133(+)CD34(+) cells increase in response to glucose load in healthy females and whether the kinetics is altered in amenorrhoeic women. The other objective of the work was to compare the endothelial differentiation potential of peripheral blood-derived endothelial progenitor cells (EPCs) from healthy versus amenorrhoeic women. METHODS: In this case-control study, 44 amenorrhoeic subjects and 36 age-matched females with no menstrual disturbance were recruited at Apollo Hospitals, a Tertiary health care center in Chennai, India. Circulating bone marrow-derived stem cells were measured by two color direct flow cytometry. Cultured progenitor cells were characterized at Day 7 and 14 for expression of endothelial markers and production of nitric oxide (NO) via immunofluoroscence. RESULTS: The amenorrhoeic subjects were insulin resistant with homeostatic model of assessment of insulin resistance values of 3.33 ± 0.3 versus 1.75 ± 0.148 observed for controls (P< 0.0001). Among the amenorrhoeic subjects, 38 subjects had polycystic ovaries with no signs of hyperandrogenism. Fasting levels of CD133(+), CD34(+) and CD133(+)CD34(+) cells were reduced in amenorrhoeic subjects (P< 0.001). There was a 1.5 to 2-fold increase in the circulating levels of these cells in response to 75 g oral glucose challenge at 1 and 2 h post-load conditions in controls, which was significantly blunted for CD133(+) (P< 0.001) and CD133(+)CD34(+) (P< 0.001) cells in amenorrhoeic subjects. A positive correlation was observed between estrogen and fasting CD133(+) (r= 0.205, P= 0.070), CD34(+) (r= 0.249, P= 0.027) and CD133(+)CD34(+) (r= 0.217, P= 0.055) cell counts. Additionally, fasting counts for CD34(+) and CD133(+)CD34(+) cells positively correlated with FSH and inversely correlated with LH and C-peptide in the polycystic group. Cultured cells from polycystic subjects exhibited reduced adherence to fibronectin and expressed lower levels of endothelial nitric-oxide synthase and NO. CONCLUSIONS: Oral glucose-induced increase in circulating numbers of CD133(+) and CD133(+)CD34(+) cells and endothelial differentiation potential of peripheral blood-derived EPCs is attenuated in insulin resistant amenorrhoeic subjects.

RESUMO

PURPOSE: To report the long-term management of a case of premature ovarian insufficiency of unknown origin in a young woman with Crohn's disease. METHOD: Here is reported the case of a 20 years old woman with Crohn's disease presenting with two years amenorrhea and FSH and LH levels of 255 mIU/ml and 182 mIU/ml respectively, who received 10 months corticosteroid treatment followed by 7 years of estro-progestin treatment. RESULTS: Corticosteroid treatment was ineffective in restoring patients gonadotropin levels as well as ovarian volume, while estro-progestins promoted a prompt reduction in gonadotrophin levels, which returned in the normal range after two years of treatment, as well as restoration of ovarian function, which occurred after four years of estrogens administration, as demonstrated by normal ovarian volume and ovulatory follicles at ultrasound, and by the re-establishment of regular menses after estroprogestin discontinuation. CONCLUSIONS: Long-term suppression of the endogenous gonadotropins using estroprogestins may be suggested as a treatment able to restore ovarian responsiveness even in patients with premature ovarian insufficiency showing highly elevated gonadotropin levels.

RESUMO

Virilization in an adolescent patient can occur for multiple reasons (ovarian, suprarenal or exogenous reasons). We describe a 14-year-old patient with 1-year secondary amenorrhea, who had an ovarian mature teratoma as a cause of her clinical history.

RESUMO

OBJECTIVE: To analyze the relationship between karyotypes and clinic features of patients with primary amenorrhea. METHODS: G banding was done for 340 patients with primary amenorrhea to facilitate individual chromosome identification, and if specific staining for certain portions of the chromosome was necessary, C banding was used. The clinical data were recorded by physical examination and ultrasound scanning. RESULTS: Karyotype analysis of the 340 patients revealed that 180 (52.94%) patients had normal female karyotypes and 160 (47.06%) patients had abnormal karyotypes. The abnormal karyotypes included abnormal X chromosome (150 patients), mosaic X-Y chromosome (4 patients), abnormal autosome (5 patients), and X-autosome translocation (1 patient). The main clinical manifestations in patients with primary amenorrhea were primordial or absent uterus (95.9%), invisible secondary sex features (68.8%), little or absent ovary (62.6%), and short stature (30.0%). The incidence of short stature in patients with X chromosome aberration (46%, 69/150) was significangly higher that in patients with 46, XX (9.44%, 17/180) as well as 46, XY (6.67%, 3/45; Chi square = 146.25, P=0.000). All primary amenorrhea patients with deletion or break-point at Xp1 1.1-11.4 were short statures. CONCLUSIONS: One of the main reasons of primary amenorrhea is choromosome abnormality, especially heterosome abnormality. It implies the need to routinely screen chromosomal anomalies for such patients. There might be relationship between Xp1 1.1-11.4 integrity and height improvement.
