Clinical practice guidelines for the care of girls and women with Turner syndrome. Eur J Endocrinol 2024; 190:G53-G151. [PMID: 38748847 DOI: 10.1093/ejendo/lvae050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Accepted: 04/19/2024] [Indexed: 06/16/2024]
Abstract
Turner syndrome (TS) affects 50 per 100 000 females. TS affects multiple organs through all stages of life, necessitating multidisciplinary care. This guideline extends previous ones and includes important new advances, within diagnostics and genetics, estrogen treatment, fertility, co-morbidities, and neurocognition and neuropsychology. Exploratory meetings were held in 2021 in Europe and United States culminating with a consensus meeting in Aarhus, Denmark in June 2023. Prior to this, eight groups addressed important areas in TS care: (1) diagnosis and genetics, (2) growth, (3) puberty and estrogen treatment, (4) cardiovascular health, (5) transition, (6) fertility assessment, monitoring, and counselling, (7) health surveillance for comorbidities throughout the lifespan, and (8) neurocognition and its implications for mental health and well-being. Each group produced proposals for the present guidelines, which were meticulously discussed by the entire group. Four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with systematic review of the literature. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with members from the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology, the European Reference Network on Rare Endocrine Conditions, the Society for Endocrinology, and the European Society of Cardiology, Japanese Society for Pediatric Endocrinology, Australia and New Zealand Society for Pediatric Endocrinology and Diabetes, Latin American Society for Pediatric Endocrinology, Arab Society for Pediatric Endocrinology and Diabetes, and the Asia Pacific Pediatric Endocrine Society. Advocacy groups appointed representatives for pre-meeting discussions and the consensus meeting.

Abstract
Context Liver function abnormalities have been reported in patients with Turner syndrome (TS); however, the pathophysiological mechanisms have not been well elucidated. Low-grade inflammation has been associated with metabolic dysfunction-associated steatotic liver disease. Objective We studied systemic inflammatory indices [aspartate transaminase to lymphocyte ratio index (ALRI), aspartate transaminase to platelet ratio index (APRI), gamma-glutamyl transferase to platelet ratio (GPR), neutrophil-lymphocyte-ratio (NLR), and platelet lymphocyte ratio and examined their associations with the hepatic abnormalities observed in these subjects. Methods We performed a retrospective analysis of the medical records of 79 patients with TS (mean age 32.5 ± 9.2 SD years) who were treated at the University Hospital of Nancy. Using matched-pair analyses based on age and body mass index (BMI), we compared 66 patients with TS (25.6 ± 7.3 years; BMI 25.9 ± 6.3 kg/m2) to 66 healthy control participants (24.7 ± 6.8 years; BMI 26 ± 6.7 kg/m2). Results Liver function abnormalities were present in 57% of the patients with TS. The ALRI, APRI, GPR, and NLR were significantly greater in patients with TS who presented with liver dysfunction than in patients with TS who had normal liver function. According to the matched-pair analyses, the ALRI, APRI, and GPR were greater in patients with TS than in healthy control participants. Logistic regression revealed that a diagnosis of TS was significantly associated with ALRI, APRI, and GPR and liver dysfunction. Conclusion Noninvasive inflammatory indices (ALRI, APRI, and GPR) might be a promising indicators of liver dysfunction in patients with TS. Future prospective studies are needed to confirm our findings and to explore the clinical significance and prognostic value of systemic inflammatory indices in Turner syndrome.

Abstract
Nonalcoholic fatty liver disease (NAFLD), recently proposed to be renamed to metabolic dysfunction-associated steatotic liver disease (MASLD), is a major global public health concern, affecting approximately 25-30% of the adult population and possibly leading to cirrhosis, hepatocellular carcinoma, and liver transplantation. The liver is involved in the actions of sex steroids via their hepatic metabolism and production of the sex hormone-binding globulin (SHBG). Liver disease, including NAFLD, is associated with reproductive dysfunction in men and women, and the prevalence of NAFLD in patients with hypogonadism is considerable. A wide spectrum of possible pathophysiological mechanisms linking NAFLD and male/female hypogonadism has been investigated. As therapies targeting NAFLD may impact hypogonadism in men and women, and vice versa, treatments of the latter may affect NAFLD, and an insight into their pathophysiological pathways is imperative. This paper aims to elucidate the complex association between NAFLD and hypogonadism in men and women and discuss the therapeutic options and their impact on both conditions.

Abstract
While the association of metabolic dysfunction-associated steatotic liver disease (MASLD) with obesity and insulin resistance is widely appreciated, there are a host of complex interactions between the liver and other endocrine axes. While it can be difficult to definitively distinguish direct causal relationships and those attributable to increased adipocyte mass, there is substantial evidence of the direct and indirect effects of endocrine dysregulation on the severity of MASLD, with strong evidence that low levels of growth hormone, sex hormones, and thyroid hormone promote the development and progression of disease. The impact of steroid hormones, e.g. cortisol and dehydroepiandrosterone, and adipokines is much more divergent. Thoughtful assessment, based on individual risk factors and findings, and management of non-insulin endocrine axes is essential in the evaluation and management of MASLD. Multiple therapeutic options have emerged that leverage various endocrine axes to reduce the fibroinflammatory cascade in MASH.

Abstract
Context Turner syndrome (TS) is a rare genetic syndrome with an increased mortality, mainly attributed to cardiovascular disease. Objective This work aimed to investigate and correlate the lipid profile in adult women with TS to clinical characteristics. Methods A 12-year prospective cohort study, including 4 study visits, was conducted at a specialist hospital. A total of 102 women with TS qualified for inclusion. Excluding missing variables and participants lost to follow-up, 86 women (mean age 38.1 years; range, 18.4-62.1 years) were included in this study. Fifty-three women completed the study. Repeated-measurement analysis was performed, using total cholesterol (Total-C), low-density lipoprotein (LDL), triglycerides (TGs), and high-density lipoprotein (HDL) as outcome variables and age, karyotype, body mass index (BMI), treatment with statins, antidiabetics, and hormone replacement therapy as explanatory variables. Principal component analysis (PCA) and partial least squares (PLS) analysis were performed at the first study visit. Results Hyperlipidemia was present in 30% of the TS cohort. Total-C increased with age (0.12 mmol/L/y; P = .016). LDL (P = .08), TGs (P = .14), and HDL (P = .24) were not associated with age. BMI significantly increased total-C (0.19 mmol/L/kg/m2; P = .006), LDL (0.63 mmol/L/kg/m2; P < .001), and TGs (0.80 mmol/L/kg/m2; P < .001) and decreased HDL (-0.59 mmol/L/kg/m2; P < .001). PCA and PLS analysis found correlations between weight and BMI and total-C, LDL, and TGs. Conclusion Hyperlipidemia is more prevalent in adult women with TS across adulthood compared to the background population. Total-C, LDL, TGs, and HDL were significantly associated with BMI characterizing the atherogenic profile in adult women with TS.

Abstract
CONTEXT Liver function abnormalities (LFAs) have been described in patients with Turner syndrome (TS). Although a high risk of cirrhosis has been reported, there is a need to assess the severity of liver damage in a large cohort of adult patients with TS. OBJECTIVE Evaluate the types of LFAs and their respective prevalence, search for their risk factors, and evaluate the severity of liver impairment by using a noninvasive fibrosis marker. METHODS This was a monocentric retrospective cross-sectional study. Data were collected during a day hospital visit. The main outcome measures were liver enzymes (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase), FIB-4 score, liver ultrasound imaging, elastography, and liver biopsies, when available. RESULTS 264 patients with TS were evaluated at a mean age of 31.15 ± 11.48 years. The overall prevalence of LFAs was 42.8%. The risk factors were age, body mass index, insulin resistance, and an X isochromosome (Xq). The mean FIB-4 sore of the entire cohort was 0.67 ± 0.41. Less than 10% of patients were at risk of developing fibrosis. Cirrhosis was observed in 2/19 liver biopsies. There was no significant difference in the prevalence of LFAs between premenopausal patients with natural cycles and those receiving hormone replacement therapy (P = .063). A multivariate analysis adjusted for age showed no statistically significant correlation between hormone replacement therapy and abnormal gamma-glutamyl transferase levels (P = .12). CONCLUSION Patients with TS have a high prevalence of LFA. However, 10% are at high risk of developing fibrosis. The FIB-4 score is useful and should be part of the routine screening strategy. Longitudinal studies and better interactions with hepatologists should improve our knowledge of liver disease in patients with TS.

Abstract
Turner syndrome (TS) is a condition in females missing the second sex chromosome (45,X) or parts thereof. It is considered a rare genetic condition and is associated with a wide range of clinical stigmata, such as short stature, ovarian dysgenesis, delayed puberty and infertility, congenital malformations, endocrine disorders, including a range of autoimmune conditions and type 2 diabetes, and neurocognitive deficits. Morbidity and mortality are clearly increased compared with the general population and the average age at diagnosis is quite delayed. During recent years it has become clear that a multidisciplinary approach is necessary toward the patient with TS. A number of clinical advances has been implemented, and these are reviewed. Our understanding of the genomic architecture of TS is advancing rapidly, and these latest developments are reviewed and discussed. Several candidate genes, genomic pathways and mechanisms, including an altered transcriptome and epigenome, are also presented.

Abstract
BACKGROUND & AIMS Liver disease in children with Turner Syndrome (TS) is poorly understood relative to associated growth, cardiac and reproductive complications. This study sought to better characterize hepatic abnormalities in a large national cohort of youth with TS. METHODS Using electronic health record data from PEDSnet institutions, 2145 females with TS were matched to 8580 females without TS on eight demographic variables. Outcomes included liver enzymes (AST and ALT) stratified as normal, 1-2 times above the upper limit of normal (ULN), 2-3 times ULN and >3 times ULN, as well as specific liver disease diagnoses. RESULTS Fifty-eight percent of youth with TS had elevated liver enzymes. Patients with TS had higher odds of enzymes 1-2 times ULN (OR: 1.7, 95% CI: 1.4-1.9), 2-3 times ULN (OR: 2.7, 95% CI: 1.7-3.3) and >3 times ULN (OR: 1.7, 95% CI: 1.3-2.2). They also had higher odds of any liver diagnosis (OR: 2.4, 95% CI: 1.7-3.3), fatty liver disease (OR: 1.9, 95% CI: 1.1-3.2), hepatitis (OR: 3.7, 95% CI: 1.9-7.1), cirrhosis/fibrosis (OR: 5.8, 95% CI: 1.3-25.0) and liver tumour/malignancy (OR: 4.8, 95% CI: 1.4-17.0). In a multinomial model, age, BMI and presence of cardiovascular disease or diabetes significantly increased the odds of elevated liver enzymes in girls with TS. CONCLUSIONS Youth with TS have higher odds for elevated liver enzymes and clinically significant liver disease compared with matched controls. These results emphasize the need for clinical screening and additional research into the aetiology and treatment of liver disease in TS. LAY SUMMARY Turner Syndrome, a chromosomal condition in which females are missing the second sex chromosome, is often associated with short stature, infertility and cardiac complications. Liver abnormalities are less well described in the literature. In this study, nearly 60% of youth with TS have elevated liver enzymes. Furthermore, patients with TS had a diagnosis of liver disease more often than patients without TS. Our results support the importance of early and consistent liver function screening and of additional research to define mechanisms that disrupt liver function in paediatric TS females.

Abstract
Turner syndrome is the most common sex chromosome abnormality in women. Infertility and short stature are the most striking findings seen in these patients. Unfortunately, many girls are still being diagnosed too late and therefore early diagnosis and treatment key. Turner syndrome affects many systems of the body; therefore, a comprehensive approach is key for therapeutic intervention.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease. NAFLD often occurs associated with endocrinopathies. Evidence suggests that endocrine dysfunction may play an important role in NAFLD development, progression, and severity. Our work aimed to explore and summarize the crosstalk between the liver and different endocrine organs, their hormones, and dysfunctions. For instance, our results show that hyperprolactinemia, hypercortisolemia, and polycystic ovary syndrome seem to worsen NAFLD’s pathway. Hypothyroidism and low growth hormone levels also may contribute to NAFLD’s progression, and a bidirectional association between hypercortisolism and hypogonadism and the NAFLD pathway looks likely, given the current evidence. Therefore, we concluded that it appears likely that there is a link between several endocrine disorders and NAFLD other than the typically known type 2 diabetes mellitus and metabolic syndrome (MS). Nevertheless, there is controversial and insufficient evidence in this area of knowledge.

Abstract
The liver is often thought of as a single functional unit, but both its structural and functional architecture make it highly multivalent and adaptable. In any given physiological situation, the liver can maintain metabolic homeostasis, conduct appropriate inflammatory responses, carry out endobiotic and xenobiotic transformation and synthesis reactions, as well as store and release multiple bioactive molecules. Moreover, the liver is a very resilient organ. This resilience means that chronic liver diseases can go unnoticed for decades, yet culminate in life-threatening clinical complications once the adaptive capacity of the liver is overwhelmed. Non-alcoholic fatty liver disease (NAFLD) predisposes individuals to cirrhosis and increases liver-related and cardiovascular disease-related mortality. This Review discusses the accumulating evidence of sexual dimorphism in NAFLD, which is currently rarely considered in preclinical and clinical studies. Increased awareness of the mechanistic causes of hepatic sexual dimorphism could lead to improved understanding of the biological processes that are dysregulated in NAFLD, to the identification of relevant therapeutic targets and to improved risk stratification of patients with NAFLD undergoing therapeutic intervention.

Abstract
Significance: Nonalcoholic fatty liver disease (NAFLD) is a hepatic and systemic disorder with a complex multifactorial pathogenesis. Owing to the rising incidence of obesity and diabetes mellitus, the prevalence of NAFLD and its impact on global health care are expected to increase in the future. Differences in NAFLD exist between males and females, and among females depending on their reproductive status. Clinical and preclinical data show that females in the fertile age are more protected against NAFLD, and studies in postmenopausal women and ovariectomized animal models support a protective role for estrogens. Recent Advances: An efficient crosstalk between the liver and adipose tissue is necessary to regulate lipid and glucose metabolism, protecting the liver from steatosis and insulin resistance contributing to NALFD. New advances in the knowledge of sexual dimorphism in liver and adipose tissue are providing interesting clues about the sex differences in NAFLD pathogenesis that could inspire new therapeutic strategies. Critical Issues: Sex hormones influence key master regulators of lipid metabolism and oxidative stress in liver and adipose tissue. All these sex-biased metabolic adjustments shape the crosstalk between liver and adipose tissue, contributing to the higher protection of females to NAFLD. Future Directions: The development of novel drugs based on the protective action of estrogens, but without its feminizing or undesired side effects, might provide new therapeutic strategies for the management of NAFLD.

Abstract
The hypoestrogenic period after menopause and associated metabolic imbalance might facilitate the onset of non-alcoholic fatty liver disease (NAFLD) and its progression. The prevalence of NAFLD increases in patients experiencing premature ovarian insufficiency, as well as surgical or natural menopause. The postmenopausal period is characterized by dyslipidemia and insulin resistance associated with an increased influx of free fatty acids to the liver with consequent steatosis and further progression of NAFLD. More than half of postmenopausal women with diabetes mellitus type 2 suffer from NAFLD. It is suggested that estrogens slow the progression of chronic liver diseases by suppression of inflammation, improvement of mitochondrial function, alleviation of oxidative stress, insulin resistance, and fibrogenesis. The hyperandrogenic state of polycystic ovary syndrome (PCOS) is associated with the development of NAFLD in women of reproductive age, but it is difficult to extend these findings to menopause due to inappropriate diagnosis of PCOS after menopause. Lifestyle intervention, including physical activity and dietary regimens, remains the first-line preventive and therapeutic option for NAFLD. There are contradictory reports on the use of menopausal hormonal therapy (MHT) and NAFLD. It is necessary to investigate the potential effects of estradiol dose, progesterone type, selective estrogen receptor modulators and tissue-selective estrogen complex compounds on NAFLD development and progression in postmenopausal women. The present review aims to explore the pathophysiological and clinical aspects of liver metabolic disturbances in women after menopause, focusing on the possible preventive and therapeutic strategies in NAFLD, including the potential role of MHT.

Abstract
BACKGROUND Nonalcoholic fatty liver disease is common and is associated with rising morbidity and mortality in the UK. Cardiovascular disease is the main cause of death in people with nonalcoholic fatty liver disease. AIMS To determine the association between baseline cardiovascular risk factors with fatty liver index, and to investigate the association between fatty liver index and the incidence of cardiovascular disease in the UK. METHODS This study is a population-based retrospective cohort study using the UK Biobank database. RESULTS The mean fatty liver index in the study cohort was 44.9, and 33.7% met the criteria for nonalcoholic fatty liver disease. Fatty liver index was significantly associated with a wide range of cardiovascular risk factors at baseline. During a mean follow-up of 7.86 years, the combined incidence of cardiovascular disease was 6.92 per 1000-person years at risk. We found significant association between fatty liver index and incident cardiovascular disease in the fully adjusted model. We found significant association between fatty liver index and incident cardiovascular disease in subgroups stratified by BMI as well as subgroups with fatty liver index < 30, < 60, and ≥ 60. CONCLUSIONS Fatty liver index not only predicts NAFLD diagnosis, but also indicates baseline and future development of cardiovascular disease on long-term follow-up across weight categories and fatty liver index spectrum. These findings can inform clinicians and other stakeholders on cardiovascular disease management and preventive efforts. Patients with high fatty liver index should be counseled on the increased future risk of developing cardiovascular disease.

Abstract
Turner Syndrome (TS) is the most common female sex chromosome aneuploidy in females, and patients may present with hypergonadotropic hypogonadism due to gonadal dysgenesis. Timing and modalities of pubertal induction in these patients is still a matter of debate. Aim of this review was to focus on the latest update on pubertal induction in TS. Based on literature data, the following practical approach to this issue is recommended. Pubertal induction should begin between 11 and 12 years of age, starting with low doses of estradiol to preserve height potential. Transdermal 17β-Estradiol (17β-E2) could represent the first-choice induction regimen as it is more physiologic compared to an oral regimen and avoids the first-pass mechanism in the liver. In the case of poor compliance, administration of oral 17β-E2 or ethinyl estradiol could be offered. Incremental dose increases, approximately every 6 months, can contribute to mimic normal pubertal progression until adult dosing is reached over a 2- to 3-year period. Progestin should be added once breakthrough bleeding occurs or after 2 to 3 years of estrogen therapy or if ultrasound shows a mature uterus with thick endometrium. Treatment needs to be individualized and monitored by clinical assessment in relation to patient compliance and satisfaction. Well-designed prospective randomized clinical trials aimed to identify the best estrogen regimen for pubertal induction in TS girls are needed.

Abstract
Short stature, ovarian dysgenesis, infertility, and cardiovascular malformations are classic features in Turner syndrome (TS), but the phenotypical spectrum is wide. Through early diagnosis and appropriate treatment, TS patients have a chance to achieve satisfactory adult height and sexual development. The doses of recombinant growth hormone (rGH) used are usually higher than the substitution dose. The safety aspects of this therapy are very important, especially in terms of the cardiovascular system. The presented study aimed to analyze how the rGH therapy may influence the cardiovascular system in TS based on current literature data. We conducted a systematic search for studies related to TS, cardiovascular system, and rGH therapy. The results show that rGH seems to have a positive effect on lipid parameters, reducing the risk of ischemic disease. It is additionally optimized by estradiol therapy. Although rGH may increase insulin resistance, the metabolic derangement is rare, probably due to lower fat content and an increase in lean body mass. Several studies showed that rGH treatment could cause aorta widening or increase the aorta growth rate. IGF-1 can be independently associated with increased aortic diameters. The studies analyzing the impact of GH on blood pressure show conflicting data. The proper cardiovascular imaging before and during rGH treatment and detecting the known risk factors for aorta dissection in every individual is very important. The long-term effects of growth hormone treatment on the heart and arteries are still not available and clearly estimated and have to be monitored in the future.

Abstract
BACKGROUND Liver function test (LFT) abnormalities, which may reflect underlying pathophysiology, are a well-known feature of Turner syndrome. Less frequently, liver findings may include vascular changes and, rarely, severe liver disease. Although previous studies on children and adolescents suggest a frequency of LFT abnormalities of up to 60%, less is known about the age at onset and natural history. METHODS We report a now 19-year-old young woman with Turner syndrome mosaicism with elevated transaminase levels first detected at the age of 2 years. We also present a retrospective analysis of 179 girls and women followed in the MassGeneral Hospital Turner Syndrome Clinic. RESULTS In the index case, the severity of liver function test abnormalities fluctuated without complete resolution from 2 to 18 years of age. In the full cohort of 179 patients, when lab results were available, elevated ALT levels occurred in 16 (11%) subjects of all ages, and in 5 (10%) patients ≤18 years of age. Significant and persistent ALT elevations occurred in 2 patients <10 years of age. CONCLUSION The updated Clinical Practice Guidelines for the care of girls and women with Turner syndrome recommend annual liver function tests throughout the lifespan, starting at the age of 10 years. Based on our data showing persistent elevation of at least one liver enzyme, we recommend a prospective and more comprehensive study of liver function in younger patients with Turner syndrome. An improved estimate of prevalence could better inform age-adjusted guidelines.

Abstract
Turner's or Turner syndrome (TS) is the most prevalent chromosomal abnormality in live female births. Patients with TS are predisposed to an increased risk of cardiovascular diseases (CVD), mainly due to the frequently observed congenital structural cardiovascular defects, such as valvular and aortic abnormalities (coarctation, dilatation, and dissection). The increased prevalence of cardiometabolic risk factors, such as arterial hypertension, insulin resistance, diabetes mellitus, dyslipidaemia, central obesity, and increased carotid intima-media thickness, also contribute to increased morbidity and mortality in TS patients. Menopausal hormone therapy (MHT) is the treatment of choice, combined with growth hormone (GH). Although MHT may, in general, ameliorate CVD risk factors, its effect on CVD mortality in TS has not yet been established. The exact effect of GH on these parameters has not been clarified. Specific considerations should be provided in TS cases during pregnancy, due to the higher risk of CVD complications, such as aortic dissection. Optimal cardiovascular monitoring, including physical examination, electrocardiogram, CVD risk factor assessment, and transthoracic echocardiography, is recommended. Moreover, the cardiac magnetic resonance from the age of 12 years is recommended due to the high risk of aortic aneurysm and other anatomical vascular complications.

Abstract
OBJECTIVE Elevated liver function tests (LFTs) are common in adult Turner syndrome (TS) patients. Data regarding children and adolescents are lacking. To investigate the prevalence of abnormal LFTs in children and adolescents with TS during several years of observation; to evaluate the potential impact of increased body mass index (BMI) and sex hormone replacement therapy (HRT) on LFTs. METHODS The analysis included 100 girls with TS, aged 4-16 years, all of whom were receiving recombinant human growth hormone therapy. A longitudinal study was conducted which included 81 patients. RESULTS Mean BMI-standard deviation (SD) score of the subjects was 0.63 (SD: 1.53). Forty-four were being treated with HRT. Elevated LFTs were found in 34% of the patients overall (32% not receiving HRT vs 36% on HRT). The relative risk of increased LFTs was not higher in obese vs normal weight [odds ratio (OR): 0.2; 95% confidence interval (CI): 0.1-0.36, p=0.38 vs OR: 0.16; 95% CI: 0.08-0.3, p=0.1]. HRT did not increase the risk of abnormal LFTs activity (OR: 0.8; 95% CI: 0.5-1.2, p=0.37 vs OR: 0.7; 95% CI: 0.4-1.1, p=0.27). During the follow-up period (mean±SD=4.31±0.82 years), no patient developed overt liver disease. There was no significant increase nor decrease of abnormal LFT frequency in the subsequent years of follow up. CONCLUSION Constantly elevated LFTs in TS are common in children and adolescents with TS. However the causes and clinical significance remain unclear. This study suggests that obesity and HRT do not increase the risk of elevated LFTs.

Abstract
OBJECTIVE Turner syndrome (TS) is characterized by the complete or partial loss of the second sex chromosome and associated with a wide range of clinical manifestations. We aimed to assess the medical care of adult patients with TS in Germany. DESIGN Retrospective multicenter observational study. METHODS Data were collected from medical records of 258 women with TS treated between 2001 and 2017 in five non-university endocrinologic centers in Germany. RESULTS Mean age was 29.8 ± 11.6 years, mean height 152 ± 7.7 cm, and mean BMI 26.6 ± 6.3 kg/m2. The karyotype was known in 50% of patients. Information on cholesterol state, liver enzymes, and thyroid status was available in 81-98% of women with TS; autoimmune thyroiditis was diagnosed in 37%. Echocardiography was performed in 42% and cardiac MRI in 8.5%, resulting in a diagnosis of cardiovascular disorder in 28%. Data on growth hormone therapy were available for 40 patients (15%) and data concerning menarche in 157 patients (61%). CONCLUSION In 258 women with TS, retrospective analysis of healthcare data indicated that medical management was focused on endocrine manifestations. Further significant clinical features including cardiovascular disease, renal malformation, liver involvement, autoimmune diseases, hearing loss, and osteoporosis were only marginally if at all considered. Based on this evaluation and in accordance with recent guidelines, we compiled a documentation form facilitating the transition from pediatric to adult care and further medical management of TS patients. The foundation of Turner Centers in March 2019 will improve the treatment of TS women in Germany.

Potential Therapeutic Application of Estrogen in Gender Disparity of Nonalcoholic Fatty Liver Disease/Nonalcoholic Steatohepatitis. Cells 2019; 8:cells8101259.

Abstract
Nonalcoholic fatty liver disease (NAFLD) caused by fat accumulation in the liver is globally the most common cause of chronic liver disease. Simple steatosis can progress to nonalcoholic steatohepatitis (NASH), a more severe form of NAFLD. The most potent driver for NASH is hepatocyte death induced by lipotoxicity, which triggers inflammation and fibrosis, leading to cirrhosis and/or liver cancer. Despite the significant burden of NAFLD, there is no therapy for NAFLD/NASH. Accumulating evidence indicates gender-related NAFLD progression. A higher incidence of NAFLD is found in men and postmenopausal women than premenopausal women, and the experimental results, showing protective actions of estradiol in liver diseases, suggest that estrogen, as the main female hormone, is associated with the progression of NAFLD/NASH. However, the mechanism explaining the functions of estrogen in NAFLD remains unclear because of the lack of reliable animal models for NASH, the imbalance between the sexes in animal experiments, and subsequent insufficient results. Herein, we reviewed the pathogenesis of NAFLD/NASH focused on gender and proposed a feasible association of estradiol with NAFLD/NASH based on the findings reported thus far. This review would help to expand our knowledge of the gender differences in NAFLD and for developing gender-based treatment strategies for NAFLD/NASH.

Abstract
Girls with either hypo- or hypergonadotropic hypogonadism need treatment with estrogens to initiate puberty and maintain a normal hormonal milieu. The focus of this review is hormone replacement treatment in girls with hypogonadism, to initiate and progress through puberty, and to maintain a healthy hormonal milieu in women. It also addresses what is known in the literature regarding estrogen levels in girls and women, instructive cases, practical tables for reference and application, and thoughts on future directions in this area. It represents a thorough literature review with author opinions and recommendations. Girls with normal ovarian function begin puberty on average at 10.5 years old, although there is variation according to ethnicity and degree of excess weight gain. The aim of estrogen therapy to initiate puberty is to mimic normal onset and rate of progression. On the basis of the currently available literature, when a diagnosis of hypogonadism is established, we recommend initiating treatment between age 11 and 12 years of age, with dose increases approximately every 6 months until adult levels are reached. In some situations, treatment may be delayed to allow time for diagnosis or permit more time for linear growth, or address unique risks found in girls treated for various cancers or blood disorders. When adult dosing is reached, progestins are also used to protect uterine health. This can be combined sequentially, allowing regular menstruation, or combined continuously when menstrual bleeding is not preferred. Treatment is continued until the average age of menopause, again with various considerations for longer or shorter duration on the basis of risk-benefit ratios. Transdermal estrogens are considered the most physiologic replacement and theoretically might have fewer associated risks. We review what is known about risks and outcomes and areas for future research.

Abstract
Turner syndrome is a rare condition in women that is associated with either complete or partial loss of one X chromosome, often in mosaic karyotypes. Turner syndrome is associated with short stature, delayed puberty, ovarian dysgenesis, hypergonadotropic hypogonadism, infertility, congenital malformations of the heart, endocrine disorders such as type 1 and type 2 diabetes mellitus, osteoporosis and autoimmune disorders. Morbidity and mortality are increased in women with Turner syndrome compared with the general population and the involvement of multiple organs through all stages of life necessitates a multidisciplinary approach to care. Despite an often conspicuous phenotype, the diagnostic delay can be substantial and the average age at diagnosis is around 15 years of age. However, numerous important clinical advances have been achieved, covering all specialty fields involved in the care of girls and women with Turner syndrome. Here, we present an updated Review of Turner syndrome, covering advances in genetic and genomic mechanisms of disease, associated disorders and multidisciplinary approaches to patient management, including growth hormone therapy and hormone replacement therapy.

Abstract
Turner syndrome is recognized now as a syndrome familiar not only to pediatricians and pediatric specialists, medical geneticists, adult endocrinologists, and cardiologists, but also increasingly to primary care providers, internal medicine specialists, obstetricians, and reproductive medicine specialists. In addition, the care of women with Turner syndrome may involve social services, and various educational and neuropsychologic therapies. This article focuses on the recognition and management of Turner syndrome from adolescents in transition, through adulthood, and into another transition as older women. It can be viewed as an interpretation of recent international guidelines, complementary to those recommendations, and in some instances, an update. An attempt was made to provide an international perspective. Finally, the women and families who live with Turner syndrome and who inspired several sections, are themselves part of the broad readership that may benefit from this review.

Effects of Estrogen Therapies on Outcomes in Turner Syndrome: Assessment of Induction of Puberty and Adult Estrogen Use. J Clin Endocrinol Metab 2019; 104:2820-2826.

Abstract
CONTEXT Turner syndrome (TS) is often associated with delayed puberty. To induce puberty, estrogen is administered in incremental doses at an age determined by age of presentation. After puberty, various types of maintenance estrogen replacement therapy (ERT) are used. OBJECTIVE We sought associations between age of induction of puberty and type of ERT on adult health outcomes. DESIGN Health surveillance data included blood profiles, bone density, and blood pressure. We assessed interactions between these data and age at first estrogen exposure in women with primary amenorrhea. We also assessed these data according to ERT subgroups [combined oral contraceptive pill (OCP), oral estrogen (OE), and transdermal estradiol (TE)] using data from each of 6679 clinic visits, controlling for age, body mass index, and height. SETTING Adult TS clinic at University College London Hospital. PATIENTS Of 799 women with TS, 624 had primary amenorrhea and 599 had accurate maintenance ERT data. MAIN OUTCOME MEASURES Parameters of health surveillance derived from clinical guidelines. RESULTS Estrogen start age was negatively correlated with adult bone density (spine: r = -0.20 and hip: r = -0.022; P ≤ 0.001). OCP users had higher blood pressure and an adverse lipid profile compared with other ERT subgroups. TE was associated with elevated liver enzymes and hemoglobin A1c compared with OE (P ≤ 0.01). CONCLUSIONS An earlier age of induction of puberty may be beneficial for adult bone density. Given the high prevalence of hypertension in TS, the use of OCP for ERT should be limited. OE may be a benefit for steatohepatitis.

Abstract
Secondary nonalcoholic fatty liver disease (NAFLD) defines those complex pathophysiological and clinical consequences that ensue when the liver becomes an ectopic site of lipid storage owing to reasons other than its mutual association with the metabolic syndrome. Disorders affecting gonadal hormones, thyroid hormones, or growth hormones (GH) may cause secondary forms of NAFLD, which exhibit specific pathophysiologic features and, in theory, the possibility to receive an effective treatment. Here, we critically discuss epidemiological and pathophysiological features, as well as principles of diagnosis and management of some common endocrine diseases, such as polycystic ovary syndrome (PCOS), hypothyroidism, hypogonadism, and GH deficiency. Collectively, these forms of NAFLD secondary to specific endocrine derangements may be envisaged as a naturally occurring disease model of NAFLD in humans. Improved understanding of such endocrine secondary forms of NAFLD promises to disclose novel clinical associations and innovative therapeutic approaches, which may potentially be applied also to selected cases of primary NAFLD.

Abstract
INTRODUCTION Hepatocellular adenoma (HCA) is a rare benign tumor and is related to the use of an oral contraceptive pill. Turner's syndrome requires various hormone replacement therapies, including the pill which is used as a female hormone replacement therapy. Herein we report a case of Turner's syndrome with HCA treated by liver segmentectomy. PRESENTATION OF CASE A 36-year-old woman with Turner's syndrome was treated with oral contraceptive pills as a female hormone replacement therapy for 20 years. She presented with fatigue and liver tumor. Liver tumors in the posterior lobe measuring 60 mm and 10 mm in diameter were detected on CT; hence, she was referred to our department. Both the tumors showed high intensity in the arterial phase, iso-intensity in the portal and late phases, and low intensity in the hepatobiliary phase on Gb-EOB-MRI. She was diagnosed with multiple HCAs and underwent segmentectomy Section 7. Pathologically, both the tumors were diagnosed as HCAs, and inflammatory markers were detected by immunohistochemistry. Thirteen months postoperatively, she was doing well and there was no evidence of recurrence of HCA without the pill. DISCUSSION There is only one report of HCA in patients with TS (Espat et al., 2000). We reported a case of multiple HCAs in a patient with TS underwent hepatectomy. CONCLUSION With the use of the contraceptive pill as a long-term female hormone replacement therapy for Turner's syndrome, careful attention is required for HCA.

Abstract
OBJECTIVE Abnormal liver function tests (LFTs) are frequent in Turner syndrome (TS). The causes and clinical significance are unclear. AIMS To investigate the prevalence of elevated LFTs in adult TS; secondly, to analyse the associations between elevated LFTs, TS-karyotypes and TS-related conditions; and thirdly, to evaluate liver stiffness and histological assessment. METHODS A total of 125 TS women were retrospectively studied. Karyotypes, clinical and biochemical details and aortic measurements were recorded. Fibroscan and liver biopsy results were noted. RESULTS Elevated LFTs were found in 49.6%: gamma-glutamyltransferase (GGT) in 88.7%, ALK in 45.2%, ALT in 40.3% and AST in 29%. A FIB-4 index >1.3 was found in 11.8%. Women with isochromosome of the X long arm, iso[X](q), had a higher prevalence of elevated LFTs. A lower prevalence of abnormal GGT was found in patients with 45,X/46,XX, 45,X/47,XXX or 45,X/46,XX/47,XXX. Subjects with raised GGT were older, shorter and more likely to have higher triglyceride levels. There was no association with HRT duration after adjusting for age. Among patients with elevated aminotransferases, no differences were noted, except for higher HDL-cholesterol levels. The sinuses and ascending aorta diameter were greater in the elevated LFTs group. Fibroscan was suggestive of significant liver fibrosis in 38.1%. Among 11 biopsies, liver architectural changes were reported in 45.4%, including two with cirrhosis. CONCLUSIONS Elevated LFTs in TS are common and important to detect given the possible progression towards severe liver disease. An association between raised LFTs and karyotype iso[X]q was demonstrated. We have also shown a new association between abnormal LFTs and aortic dilatation.

Abstract
Transition from pediatric to adult care for young women with Turner Syndrome (TS) is characterized by high drop-out rates and inadequate follow-up, leading to increased morbidity and mortality. The complexity of the health issues young women with TS face or new problems that may arise warrants a well-structured and efficiently coordinated gradual transition plan, which is adapted to the individual needs of the emerging young adult and is based on interdisciplinary communication between physicians. In order to achieve a high level of care, it is important for the patient to be sincerely informed about her condition but also supported throughout this critical period of rising responsibility and autonomy by an experienced, multidisciplinary team. In this review, we present the basic concepts that should characterize transition and the major health issues that should be thoroughly addressed, including growth, Hormone Replacement Treatment and fertility options, cardiovascular disease, bone health, gastrointestinal disorders, autoimmunity, orthopaedic and ENT issues, as well as the overall psychological well-being of the young adult with TS.

Abstract
CONTEXT Most girls with Turner syndrome (TS) have hypergonadotropic hypogonadism and need hormonal replacement for induction of puberty and then for maintaining secondary sex characteristics, attaining peak bone mass, and uterine growth. The optimal estrogen replacement regimen is still being studied. EVIDENCE ACQUISITION We conducted a systematic search of PubMed for studies related to TS and puberty. EVIDENCE SYNTHESIS The goals of replacement are to mimic normal timing and progression of physical and social development while minimizing risks. Treatment should begin at age 11 to 12 years, with dose increases over 2 to 3 years. Initiation with low-dose estradiol (E2) is crucial to preserve growth potential. Delaying estrogen replacement may be deleterious to bone and uterine health. For adults who have undergone pubertal development, we suggest transdermal estrogen and oral progestin and discuss other approaches. We discuss linear growth, lipids, liver function, blood pressure, neurocognition, socialization, and bone and uterine health as related to hormonal replacement. CONCLUSION Evidence supports the effectiveness of starting pubertal estrogen replacement with low-dose transdermal E2. When transdermal E2 is unavailable or the patient prefers, evidence supports use of oral micronized E2 or an intramuscular preparation. Only when these are unavailable should ethinyl E2 be prescribed. We recommend against the use of conjugated estrogens. Once progestin is added, many women prefer the ease of use of a pill containing both an estrogen and a progestin. The risks and benefits of different types of preparations, with examples, are discussed.

Abstract
Turner syndrome affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating multidisciplinary approach to care. Previous guidelines have highlighted this, but numerous important advances have been noted recently. These advances cover all specialty fields involved in the care of girls and women with TS. This paper is based on an international effort that started with exploratory meetings in 2014 in both Europe and the USA, and culminated with a Consensus Meeting held in Cincinnati, Ohio, USA in July 2016. Prior to this meeting, five groups each addressed important areas in TS care: 1) diagnostic and genetic issues, 2) growth and development during childhood and adolescence, 3) congenital and acquired cardiovascular disease, 4) transition and adult care, and 5) other comorbidities and neurocognitive issues. These groups produced proposals for the present guidelines. Additionally, four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with a separate systematic review of the literature. These four questions related to the efficacy and most optimal treatment of short stature, infertility, hypertension, and hormonal replacement therapy. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with The European Society for Pediatric Endocrinology, The Endocrine Society, European Society of Human Reproduction and Embryology, The American Heart Association, The Society for Endocrinology, and the European Society of Cardiology. The guideline has been formally endorsed by the European Society for Endocrinology, the Pediatric Endocrine Society, the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology and the Endocrine Society. Advocacy groups appointed representatives who participated in pre-meeting discussions and in the consensus meeting.

Hormone signaling and fatty liver in females: analysis of estrogen receptor α mutant mice. Int J Obes (Lond) 2017; 41:945-954. [PMID: 28220039 PMCID: PMC5735425 DOI: 10.1038/ijo.2017.50] [Citation(s) in RCA: 56] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2016] [Revised: 01/11/2017] [Accepted: 02/10/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND Treatment with estrogen in early menopausal women protects against development of hepatic steatosis and nonalcoholic fatty liver disease but estrogen has undesirable side effects, which negate its beneficial effects in premenopausal and postmenopausal women. Targeted therapies require better understanding of the target sites and mechanisms by which estrogen signaling exerts its protective effects in women. Estrogen receptor α (ERα) is thought to be the primary mediator for estrogen signaling to protect against hepatic steatosis. ERα has several mechanisms for signal transduction: (1) inducing gene transcription by direct binding to specific DNA sequences, (2) inducing tethered transcription with other DNA-binding factors, and (3) stimulating nongenomic action through membrane-associated ERα. However, it is still unclear which mechanisms mediate ERα-dependent protection against hepatic steatosis. METHODS To understand the mechanisms of estrogen signaling for protection against hepatic steatosis in females, we analyzed the global ERα knockout mouse (αERKO), ERα DNA-binding domain mutant mouse (KIKO) and liver-specific ERα knockout mouse (LERKO) fed high-fat diets (HFD). The KIKO mouse disrupts the direct DNA-binding transcription activity but retains tethered transcription regulation and nongenomic action. Hepatic steatosis was evaluated by scoring the macrovesicular and microvesicular steatosis as well as serum alanine aminotransferase (ALT) levels. We analyzed serum testosterone to assess its correlation with hepatic steatosis. RESULTS Liver fat accumulation was far greater in HFD-fed αERKO and KIKO females than in HFD-fed wild-type (WT) controls. Conversely, HFD-fed LERKO females did not accumulate excess liver fat. HFD-fed αERKO and KIKO females showed higher microvesicular steatosis and ALT levels than WT controls that correlated with increased serum testosterone levels. CONCLUSIONS ERα-mediated direct transcription in non-hepatic tissues is essential for estrogen-mediated protection against hepatic steatosis in HFD-fed females. The balance between non-hepatic estrogen signaling and hepatic or non-hepatic testosterone action may control hepatic steatosis.

Abstract
Turner syndrome is the most common example of hypergonadotropic hypogonadism resulting from gonadal dysgenesis. Most patients present delayed, or even absent, puberty. Premature ovarian failure can be expected even if spontaneous menarche occurs. Laboratory markers of gonadal dysgenesis are well known. The choice of optimal hormone replacement therapy in children and adolescents remains controversial, particularly regarding the age at which therapy should be initiated, and the dose and route of estrogen administration. On the basis of a review of the literature, we present the most acceptable schedule of sex steroid replacement therapy in younger patients with Turner syndrome.

Abstract
CONTEXT Paucisymptomatic forms of Turner's syndrome (TS), in which short stature is the predominant clinical abnormality, remain underdiagnosed. Abnormal liver tests are extremely frequent in adult TS patients reflecting various types of hepatic lesions. OBJECTIVE The objective of the study was to investigate whether unexplained elevated liver enzymes in women with short stature could reveal X chromosome abnormalities of undiagnosed TS. DESIGN AND PARTICIPANTS Thirty-one consecutive short stature women displaying elevated liver enzymes and no previous diagnosis of TS were compared with 31 age-matched controls in a prospective study. Liver biopsy was performed in 26 patients. MAIN OUTCOME MEASURES Systematic karyotype analysis and fluorescence in situ hybridization. RESULTS X chromosome abnormalities were found in 27 patients and one control (87.0% vs 3.2%, P < .0001), including a 45,X/46,XX mosaicism in 24 patients and isochromosome of the long arm in three. Liver histological analysis showed architectural changes in 17 patients with nodular regenerative hyperplasia in 12. Biliary lesions were present in 13 patients and liver steatosis in 20. CONCLUSIONS X chromosome abnormalities indicative of cryptic TS are extremely frequent in short-stature women with unexplained elevated liver enzymes. In short-stature women, abnormal liver tests should lead to systematic karyotype analysis.

Abstract
Transition in health care for young patients with Turner's syndrome (TS) should be perceived as a staged but uninterrupted process starting in adolescence and moving into adulthood. As a condition associated with high risk of short stature, cardiovascular diseases, ovarian failure, hearing loss and hypothyroidism, TS requires the attention of a multidisciplinary team. In this review paper, we systematically searched the relevant literature from the last decade to discuss the array of problems faced by TS patients and to outline their optimal management during the time of transfer to adult service. The literature search identified 233 potentially relevant articles of which 114 were analysed. The analysis confirmed that all medical problems present during childhood should also be followed in adult life. Additionally, screening for hypertension, diabetes mellitus, dyslipidaemia, and osteoporosis is needed. After discharge from the paediatric clinic, there is still a long way to go.

Abstract
BACKGROUND An increased relative risk of diabetes, ischemic heart disease, atherosclerosis, and hypertension have been reported in Turner syndrome (TS) patients. No data are currently available on the prevalence of metabolic syndrome in TS subjects. We evaluated the frequency of metabolic syndrome in obese and nonobese patients with TS. PATIENTS AND METHODS We evaluated 85 TS patients (27.05 ± 11.17 years). Obesity was defined as standard deviation score body mass index (SDS-BMI) ≥ 2 or BMI ≥ 30 kg/m(2) in adult patients. We classified metabolic syndrome according to the International Diabetes Federation (IDF). Hepatic ultrasound was performed in all girls. RESULTS The prevalence of metabolic syndrome was 4.7% (12.5% obese and 4.3% nonobese, P=0.16) and associated with visceral adiposity (P=0.008). Abnormalities in glucose metabolism and hypertension were not associated with genetic or therapeutic factors. The karyotype 45,X was associated with atherogenic profile. Pathological waist circumference was more frequent in girls treated with estro-progestin (P=0.03). Evidence of fatty liver was associated with metabolic syndrome (P=0.03) and insulin resistance (P=0.05). Elevated liver enzymes were found in 15 subjects and were not related to treatment or ultrasound abnormalities. CONCLUSIONS Prevalence of each component of metabolic syndrome in TS patients is partially influenced by genetic makeup and treatment. Hepatosteatosis was associated with metabolic syndrome and insulin resistance, but not to elevated liver enzymes.

Abstract
In female animals, energy metabolism and fertility are tightly connected, and reciprocally regulated. However, the relative contributions of metabolic and reproductive pathways have changed over the course of evolution. In oviparous animals, metabolic factors take precedence over fertility, enabling egg production to be inhibited in a nutritionally poor environment. By contrast, in placental mammals, the opposite occurs: the need to feed a developing embryo and neonate forces metabolic pathways to adapt to these reproductive needs. This physiological necessity explains why in female mammals alterations of gonadal activity, including age-dependent cessation of ovarian functions, are associated with a disruption of metabolic homeostasis and consequent inflammatory reactions that trigger the onset of metabolic, cardiovascular, skeletal and neural pathologies. This Review discusses how metabolic homeostasis and reproductive functions interact to optimize female fertility and explains the pathogenic mechanisms underlying the disordered energy metabolism associated with human ovarian dysfunction owing to menopause, polycystic ovary syndrome and Turner syndrome. Finally, this article highlights how hormone replacement therapy might aid the restoration of metabolic homeostasis in women with ovarian dysfunction.

Abstract
Liver test abnormalities are frequent in adult patients with Turner syndrome, corresponding to various pathophysiological mechanisms. Steatosis, steatofibrosis and steatohepatitis are the most frequently reported lesions, caused by metabolic disorders, which are commonly related to overweight. Marked architectural changes, including nodular regenerative hyperplasia, multiple focal nodular hyperplasia and cirrhosis, found in some patients, are associated with a risk of severe liver-related complications. Architectural changes are often observed and are associated with vascular disorders caused by congenitally abnormal vessels. Finally, small bile duct alterations resembling sclerosing cholangitis occur in several patients. Oestrogen replacement therapy does not cause liver toxicity in patients with Turner syndrome and is not contraindicated in case of elevated liver enzymes. Moreover, in recent studies, oestrogen therapy was reported to improve liver function tests. Because of the wide spectrum of potential liver injuries that may occur in Turner syndrome patients, a regular screening of liver enzymes is recommended for early detection and treatment.

Abstract
Cardiovascular disease is emerging as a cardinal trait of Turner syndrome, being responsible for half of the 3-fold excess mortality. Turner syndrome has been proposed as an independent risk marker for cardiovascular disease that manifests as congenital heart disease, aortic dilation and dissection, valvular heart disease, hypertension, thromboembolism, myocardial infarction, and stroke. Risk stratification is unfortunately not straightforward because risk markers derived from the general population inadequately identify the subset of females with Turner syndrome who will suffer events. A high prevalence of endocrine disorders adds to the complexity, exacerbating cardiovascular prognosis. Mounting knowledge about the prevalence and interplay of cardiovascular and endocrine disease in Turner syndrome is paralleled by improved understanding of the genetics of the X-chromosome in both normal health and disease. At present in Turner syndrome, this is most advanced for the SHOX gene, which partly explains the growth deficit. This review provides an up-to-date condensation of current state-of-the-art knowledge in Turner syndrome, the main focus being cardiovascular morbidity and mortality. The aim is to provide insight into pathogenesis of Turner syndrome with perspectives to advances in the understanding of genetics of the X-chromosome. The review also incorporates important endocrine features, in order to comprehensively explain the cardiovascular phenotype and to highlight how raised attention to endocrinology and genetics is important in the identification and modification of cardiovascular risk.

Abstract
The cardinal features of Turner syndrome (TS) are short stature, congenital abnormalities, infertility due to gonadal dysgenesis, with sex hormone insufficiency ensuing from premature ovarian failure, which is involved in lack of proper development of secondary sex characteristics and the frequent osteoporosis seen in Turner syndrome. But sex hormone insufficiency is also involved in the increased cardiovascular risk, state of physical fitness, insulin resistance, body composition, and may play a role in the increased incidence of autoimmunity. Severe morbidity and mortality affects females with Turner syndrome. Recent research emphasizes the need for proper sex hormone replacement therapy (HRT) during the entire lifespan of females with TS and new hypotheses concerning estrogen receptors, genetics and the timing of HRT offers valuable new information. In this review, we will discuss the effects of estrogen and androgen insufficiency as well as the effects of sex HRT on morbidity and mortality with special emphasis on evidence based research and areas needing further studies.

Abstract
AIM The aim of this study was to determine, in patients with Turner syndrome (TS), the prevalence of thrombophilic disorders correlating with a higher risk of venous thromboembolism (VTE), to evaluate if thrombophilia is associated with the genetic features of these patients and whether screening before hormone replacement therapy (HRT) is advisable. PATIENTS AND METHODS We examined 82 TS patients. In all patients we analyzed activated factor VIII:C, fibrinogen, antithrombin (AT), protein C (PC), protein S (PS), activated PC resistance, and homocysteine. For every patient, an investigation for mutations in prothrombin G20210A, factor V R506Q, methylenetetrahydropholate reductase (MTHFR) C 677T and A1298C was conducted. RESULTS Low values of PC in 3 patients (3.70%), low values of PS in 12 (14.81%), and hyperhomocysteinemia in 4 (4.87%) were found; 52 girls (64.2%) presented hyperfibrinogenemia. Three patients were heterozygous for the prothrombin G20210A allele mutation (3.66%) and the factor V mutation was present in 4 patients (4.88%). No TS patient had a homozygous mutation. Mutations in the MTHFR gene were present in 62 girls, in 17 patients (20.7%) they were homozygous and in 45 patients (54.88%) heterozygous. CONCLUSIONS Considering the increased risks with the association between VTE and the higher prevalence of PC and PS deficiencies, TT genotype mutations and high level of fibrinogen, it is advisable to perform a complete thrombophilia screening in TS patients before starting HRT.

Abstract
BACKGROUND Raised liver enzyme value is frequently detected in patients with Turner syndrome (TS), but its clinical importance is still unclear. OBJECTIVE To investigate the entity of liver involvement in TS and to avoid the invasiveness of liver biopsy, we planned to measure liver stiffness by transient elastography (TE). DESIGN Cross-sectional study. PATIENTS AND METHODS Twenty-five consecutive patients with TS and a chronological age ≥ 12·5 years (mean age = 21·7 years), full pubertal development and final height's achievement were enrolled and investigated by blood biochemical analyses [glucose, insulin, aspartate-aminotransferase (AST), alanine-aminotransferase (ALT), gamma-glutamil transferase (GGT), alkaline phosphatase, cholesterol, triglyceride, HDL-cholesterol], ultrasonography and TE of the liver. RESULTS Of 25, 7 subjects (28%) showed liver enzyme levels higher than the normal upper limit. Mean liver stiffness value in the entire study group was 4·5 ± 1·7 kPa, being significantly higher in patients with abnormal liver enzymes than in those with normal liver biochemistry (6·0 ± 2·9 vs. 4·0 ± 0·9, P < 0·05). Strong correlations were found between TE values and ALT (P < 0·005), GGT (P < 0·0001), Body mass index (P < 0·05), HOMA index (P < 0·05), HDL-cholesterol (P < 0·05) and triglycerides (P < 0·0001). CONCLUSIONS We can assert that (i) liver stiffness, measured by TE, strongly correlates with liver enzyme levels in patients with TS ; (ii) the increased liver stiffness in patients with TS with biochemical signs of liver dysfunction is significantly related to metabolic syndrome parameters; (iii) TE may be an useful tool to select among patients with TS with elevated liver enzymes or other metabolic risk factors, those who deserve more invasive diagnostic procedures, namely liver biopsy, for the best characterisation of liver damage.

Abstract
Acetaminophen overdose causes acute liver injury or even death in both humans and experimental animals. We investigated the effect of 17β-estradiol against acetaminophen-induced acute liver injury and mortality in mice. Male mice were given acetaminophen (p-acetamidophenol; 300 mg/kg; orally) to induce acute liver injury. Acetaminophen significantly increased the levels of aspartate transaminase, alanine transaminase, myeloperoxidase, lipid peroxidation, and glutathione reductase, but it decreased superoxide dismutase, catalase, and glutathione. In addition, acetaminophen-induced mortality began 4h post-treatment, and all mice died within 9h. 17β-Estradiol (200 μg/kg; i.p.) protected against acetaminophen-induced oxidative hepatic damage by inhibiting neutrophil infiltration and stimulating the antioxidant defense system. However, 17β-estradiol did not affect acetaminophen-induced glutathione depletion or increased glutathione reductase activity. We conclude that 17β-estradiol specifically attenuates acute hepatic damage and decreases mortality in acetaminophen-overdosed male mice.

Abstract
Within endocrinology, the long-term management of Turner syndrome (TS) in adults is fast becoming a specialist subject in its own right. The complications of TS can affect every system in the body, and the main reason why it falls to endocrinologists to coordinate health care is that many features are clearly within the endocrine remit: hypothyroidism, diabetes, hypertension, osteoporosis, hypogonadism. Endocrinologists as general physicians can often cover surveillance of problems in other areas such as congenital heart disease, inflammatory bowel disease and deafness, calling upon specialist input only if the need arises. In this way, a simple 'one stop shop' can offer a well-woman service for women with TS in a cost-effective manner. Such a service requires a multidisciplinary approach.
