Hepatokine Profile in Adolescents with Polycystic Ovary Syndrome: A Case-Control Study. J Clin Med 2023; 12:5744. [PMID: 37685811 PMCID: PMC10489115 DOI: 10.3390/jcm12175744] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 08/29/2023] [Accepted: 08/30/2023] [Indexed: 09/10/2023] Open
Abstract
The current guidelines suggest routine screening for non-alcoholic fatty liver disease (NAFLD) in patients with polycystic ovary syndrome (PCOS). Hepatokines seem to be promising surrogate endpoints for the diagnosis and severity of NAFLD. PCOS has its onset in adolescence and its metabolic sequalae begin during the same period. There are scarce data on the hepatokine profile of adolescent PCOS patients. This case-control study examined the serum profile of the hepatokines sex hormone-binding globulin (SHBG), selenoprotein P, fibroblast growth factor 21 (FGF21), and fetuin A in a sample of adolescent PCOS patients, and their association to metabolic and hormonal parameters. The selenoprotein P and SHBG serum concentrations were significantly decreased in PCOS patients vs. the controls (median (IQR), 2.47 (0.40) vs. 2.66 (0.36) μg/mL, p = 0.025; mean ± SD, 41.71 ± 19.41 vs. 54.94 ± 22.12 nmol/L, p = 0.011, respectively), whereas selenoprotein P was significantly and positively associated with testosterone (r = 0.325, p = 0.007) and the free androgen index (r = 0.361, p = 0.002). The SHBG demonstrated multiple significant negative correlations with adverse metabolic parameters. Among the PCOS patients, the FGF21 concentrations were significantly higher in those with NAFLD, whereas a 1 pg/mL increase in the FGF21 concentration increased the odds of NAFLD diagnosis by liver ultrasound by 1%, suggesting FGF21 as a potential biomarker for hepatic disease in females with PCOS in adolescence. Fetuin A was the least differentiated hepatokine between the PCOS patients and controls with the least associations with metabolic and hormonal parameters.

The Burden of Non-Alcoholic Fatty Liver Disease in Adolescents with Polycystic Ovary Syndrome: A Case-Control Study. J Clin Med 2023; 12:jcm12020557. [PMID: 36675485 PMCID: PMC9860755 DOI: 10.3390/jcm12020557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Revised: 12/30/2022] [Accepted: 01/06/2023] [Indexed: 01/12/2023] Open
Abstract
The aim of this case-control study was to assess the burden of non-alcoholic fatty liver disease (NAFLD) in adolescents with polycystic ovary syndrome (PCOS) and its associations with insulin resistance, hyperandrogenism, and other metabolic characteristics of the syndrome. A total of 87 Caucasian adolescent girls (47 with PCOS and 40 controls), aged 12.3-20.4 years, underwent blood sampling for glucose metabolism, hormonal and lipid profile, gynecological and liver ultrasound, and liver elastography. Indices of insulin resistance, liver steatosis, and liver fibrosis were calculated. NAFLD diagnosed by ultrasound was more prevalent in adolescents with PCOS than controls (22.7% vs. 6.1%, p = 0.046), and was also verified by liver steatosis indices. The latter was not apparent for hepatic fibrosis, as assessed by Fibroscan® and calculated indices. The homeostatic model assessment for insulin resistance (HOMA-IR) was found to predict NAFLD diagnosis by the liver fat score (LFS) index (β = 0.709, p = 0.002). Adolescents with PCOS and high free androgen index (FAI) presented worse NAFLD than those adolescents with PCOS and lower FAI. In addition, adolescents with PCOS and concurrent NAFLD had worse insulin sensitivity indices (HOMA-IR, QUICKI, and glucose to insulin ratio) than adolescents with PCOS alone. Adolescent insulin resistance could be considered a confounder of the association between PCOS and NAFLD.

Abstract
Nonalcoholic fatty liver disease (NAFLD) has emerged as the most frequent chronic liver disease globally. NAFLD is strongly associated with metabolic syndrome and it has been recently suggested that to rename NAFLD as metabolic dysfunction-associated fatty liver disease (MAFLD). NAFLD has been studied in different endocrine axes and accumulating body of clinical and experimental studies have suggested that NAFLD is associated with polycystic ovarian syndrome (PCOS), hypopituitarism, growth hormone deficiency (GHD), hypogonadism and other endocrine disorders. In fact, endocrine dysfunction may be considered as the major contributor for the development, progression, and severity of NAFLD. In the present comprehensive review, we discussed the epidemiological and clinical evidence on the epidemiology, pathophysiology, and management of NAFLD in endocrine disorders, with an emphasis on the effects of sex-specific hormones/conditions as well as molecular basis of NAFLD development in these endocrine diseases.

Abstract
CONTEXT Nonalcoholic fatty liver disease (NAFLD) describes a spectrum of liver damage due to excessive hepatic lipid accumulation. Recent research has demonstrated a high prevalence of NAFLD in women with polycystic ovary syndrome (PCOS). RESULTS Strong associations independent of body mass index (BMI) have been found between high androgen levels characteristic of PCOS, as well as insulin resistance, and the presence of NAFLD in these women, suggesting that these factors contribute to liver injury more significantly than obesity. Current studies indicate the occurrence of NAFLD in normal weight women with PCOS in addition to the commonly researched women who are overweight and obese. While the majority of studies address NAFLD in adult, premenopausal women (ages 25-40 years), the occurrence of NAFLD in young and adolescent women has gone largely unaddressed. Research in this field lacks diversity; a majority of studies either focus on populations of White women or are missing demographic information entirely. CONCLUSIONS Future studies should include larger, more racially and ethnically inclusive populations and particular attention should be paid to how excess androgens and insulin resistance contribute to the increased risk of NAFLD seen in women with PCOS of varying weights, ages, and ethnicities. OBJECTIVE AND METHODS Here, we review NAFLD in women with PCOS with subsections focused on the impact of hyperandrogenism, BMI, insulin resistance and age. Most notably, we present the most up-to-date racially and ethnically diverse worldwide prevalence of NAFLD in women with PCOS compared with women without PCOS (51.56% vs 29.64%, P < .001, respectively).

Effect of DHT-Induced Hyperandrogenism on the Pro-Inflammatory Cytokines in a Rat Model of Polycystic Ovary Morphology. ACTA ACUST UNITED AC 2020; 56:medicina56030100. [PMID: 32120970 PMCID: PMC7142739 DOI: 10.3390/medicina56030100] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2020] [Revised: 02/19/2020] [Accepted: 02/20/2020] [Indexed: 02/07/2023]
Abstract
Background and Objectives: Polycystic ovary syndrome (PCOS) is one of the most prevalent disorders among women of reproductive age. It is considered as a pro-inflammatory state with chronic low-grade inflammation, one of the key factors contributing to the pathogenesis of this disorder. Polycystic ovary is a well-established criterion for PCOS. The present investigation aimed at finding the role of hyperandrogenism, the most important feature of PCOS, in the development of this inflammatory state. To address this problem, we adopted a model system that developed polycystic ovary morphology (PCOM), which could be most effectively used in order to study the role of non-aromatizable androgen in inflammation in PCOS. Materials and Methods: Six rats were used to induce PCOM in 21-days-old female Wistar albino rats by using a pre-determined release of dihydrotestosterone (DHT), a potent non-aromatizable androgen, achieved by implanting a DHT osmotic pump, which is designed to release a daily dose of 83 μg. Results: After 90 days, the rats displayed irregular estrous cycles and multiple ovarian cysts similar to human PCOS. Elevated serum inflammatory markers such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), and the presence of a necrotic lesion in the liver, osteoclast in the femur, multinucleated giant cells and lymphocytes in the ovary based on histopathological observation of DHT-treated rats clearly indicated the onset of inflammation in the hyperandrogenic state. Our results show no significant alterations in serum hormones such as luteinizing hormone (LH), follicle stimulating hormone (FSH), insulin, and cortisol between control and hyperandrogenised rats. DHT was significantly elevated as compared to control. mRNA studies showed an increased expression level of TNF-α and IL-1β, further, the mRNA expression of urocortin 1 (Ucn-1) was stupendously elevated in the liver of hyperandrogenised rats. Conclusions: Thus, results from this study provide: (1) a good PCOM model system in order to study the inflammatory changes in PCOS aspects, (2) alteration of inflammatory markers in PCOM rats that could be either due to its direct effect or by the regulation of various inflammatory genes and markers in the liver of hyperandrogenic state suggesting the regulatory role of DHT, and (3) alteration in stress-related protein in the liver of PCOM rats.

Abstract
Polycystic ovary syndrome (PCOS) affects 6-15% of women of reproductive age. Nonalcoholic fatty liver disease (NAFLD) affects 25-30% of the general population and its prevalence increases in parallel with the epidemics of obesity and type 2 diabetes mellitus. A growing body of evidence suggests that NAFLD and PCOS quite often co-exist. The aim of this article is to summarize and critically appraise the literature regarding: (1) the rates of co-existence of the two entities, (2) the possible pathophysiological links, (3) the proper diagnostic assessment and (4) the appropriate management of women with NAFLD and PCOS. Data from clinical studies and meta-analyses indicate a higher prevalence of NAFLD in women with PCOS ranging from 34% to 70% compared with 14% to 34% in healthy women. Inversely, women with NAFLD are more often diagnosed with PCOS. Insulin resistance (IR) and hyperandrogenism are two main potential pathophysiological links between the two entities. In this regard, IR seems to interplay with obesity and hyperandrogenism, thus affecting NAFLD and PCOS and being affected by them. Women with PCOS, particularly those with IR and/or hyperandrogenism, are suggested to be screened for NAFLD, while premenopausal women with NAFLD is suggested to be screened for PCOS. Lifestyle recommendations with a change in dietary habits, weight loss and exercise, constitute currently the cornerstone of the management of both NAFLD and PCOS. Insulin sensitizers maybe used for the treatment of these women, while there are limited promising data for the use of liraglutide.

Abstract
Background: There is growing evidence that non-alcoholic fatty liver disease (NAFLD) is a disease affecting not only the liver but also extrahepatic organs. Aim: To investigate whether in youths NAFLD is associated with extrahepatic complications such as subclinical atherosclerosis, cardiac abnormalities, hypertension, type 2 diabetes, decreased bone mineral density, renal dysfunction, obstructive sleep apnea, and polycystic ovary syndrome. Methods: We systematically reviewed PubMed; Scopus; Embase; and the Cochrane Library databases up to 28 February 2019 and assessed the quality of studies using the Newcastle-Ottawa Scale. Results: Thirty-five articles were selected for this systematic review: fifteen (4627 participants) evaluated the association of NAFLD with subclinical atherosclerosis; four (969 participants) with cardiac abnormalities; two (550 participants) with hypertension; four (1328 participants) with diabetes; six (523 participants) with low bone mineral density; two (865 participants) with renal dysfunction; one with obstructive sleep apnea; and one with polycystic ovary syndrome. Most studies found that youths with NAFLD have increased features of subclinical atherosclerosis; as well as of cardiac alterations. Limited data were available to endorse a solid estimate of the prevalence of diabetes; low mineral density and renal dysfunction in the pediatric NAFLD population. Conclusion: NAFLD-related intermediate CVD outcomes can occur and be detected early in young populations.

Abstract
Background Polycystic ovary syndrome (PCOS) is a common endocrine disorder among reproductive-aged women. While PCOS is associated with an increased risk of obesity and insulin resistance, little is known regarding the prevalence of and risk factors for nonalcoholic fatty liver disease (NAFLD) among Japanese women with PCOS. We estimated the prevalence of and risk factors for elevated liver enzymes, as the index of NAFLD, in Japanese women with PCOS. Methods We retrospectively reviewed 102 reproductive-aged women who visited the Department of Gynecology, Kyoto Medical Center in Japan from January 2000 to September 2016. Inclusion criterion was confirmed diagnosis of PCOS using International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10) codes. Exclusion criteria were women with a history of liver diseases, missing body mass index (BMI) and serum alanine aminotransferase (ALT) data, and pregnancy. Data regarding age; BMI; and levels of blood glucose, serum lipid, liver enzymes, and sex hormones were obtained from medical records. Elevated liver enzymes was defined as ALT > 19 IU/L. Optimal cutoffs for risk factors for elevated liver enzymes were calculated to determine predictors of elevated liver enzymes using area under the curve (AUC) by receiver-operating characteristics (ROC). Results The prevalence of elevated liver enzymes was 33.3%. BMI was significantly higher in PCOS patients than in those without elevated liver enzymes (25.3 vs. 20.7 kg/m2, P < 0.05). ROC analyses were performed using BMI and blood glucose and testosterone levels because BMI and blood glucose showed differences between the groups and testosterone is related to fatty liver. AUC of the model including BMI and blood glucose and testosterone levels was 0.861 (sensitivity, 66.7%; specificity, 100%). Conclusions These findings suggest that elevated liver enzymes are common in women with PCOS. An algorism using BMI and blood glucose and testosterone levels might be useful to determine elevated liver enzymes in women with PCOS. Our finding may be useful for the study of NAFLD among Japanese women with PCOS since several previous studies have indicated elevated liver enzymes to be related to the potential presence of NAFLD. Further examination, including abdominal ultrasonography and/or liver biopsy data, is required to confirm these results.

Abstract
In the past few decades, there has been an overwhelming increase in childhood and adolescent obesity worldwide. Besides the well recognized cardiometabolic complications and other physical conditions associated with obesity, during adolescence, it causes psychological and social distress in a period of life that is already sensitive for a girl. This in turn increases their risk of low self-esteem and depression. Furthermore, obesity diminishes health-related quality of life and years of life. Overweight and obese teenagers are more likely to have gynecologic and obstetric complications, during adolescence and also later in life. Consequences of obese and overweight childhood and adolescence include sexual maturation and reproductive dysfunction, alterations in menstruation, dysmenorrhea, risky sexual behavior, and inefficient use of contraception, polycystic ovary syndrome, bone density abnormalities, macromastia, and an increased risk of breast and endometrial cancer. Obese adolescents are at greater risk of pregnancy and perinatal complications, such as preeclampsia, gestational hypertension and preeclampsia, gestational diabetes mellitus, primary cesarean delivery, and induction of labor, to mention a few. Evidence shows that infants born to obese teenagers are also more likely to have complications including preterm or post-term delivery, small-for-gestational age newborns, macrosomia, meconium aspiration, respiratory distress, and even stillbirth, among others. This comprehensive review focuses on the gynecological and obstetric consequences of obesity in adolescent girls.

Abstract
Previous studies suggested that elevated liver enzymes could be used as potential novel biomarkers of Metabolic syndrome (MetS) and its clinical outcomes, although the results were inconsistent and the conclusions were underpowered. A case-control study with 6,268 MetS subjects and 6,330 frequency-matched healthy controls was conducted to systematically evaluated levels of four liver enzymes (ALT, AST, GGT and ALP), both in overall populations and in subjects with normal liver enzymes, with MetS risk using both quartiles and continuous unit of liver enzymes. We found significant associations were detected for all above analyses. Compared with quartile 1 (Q1), other quartiles have significant higher MetS risk, with ORs ranging from 1.15 to 18.15. The highest effected was detected for GGT, for which the OR value for the highest versus lowest quartile was 18.15 (95% CI: 15.7-20.9). Mutual adjustment proved the independence of the relations for all four liver enzymes. Sensitivity analyses didn’t materially changed the trend. To the best of our knowledge, this study should be the largest, which aimed at evaluating the association between liver enzymes measures and MetS risk. The results can better support that liver enzyme levels could be used as clinical predictors of MetS.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women. Women with PCOS frequently have metabolic complications including insulin resistance (IR), early diabetes, hypertension and dyslipidemia. Recent studies have demonstrated an association between PCOS and another metabolic complication: nonalcoholic fatty liver disease (NAFLD). NAFLD occurs as a result of abnormal lipid handling by the liver, which sensitizes the liver to injury and inflammation. It can progress to nonalcoholic steatohepatitis (NASH), which is characterized by hepatocyte injury and apoptosis. With time and further inflammation, NASH can progress to cirrhosis. Thus, given the young age at which NAFLD may occur in PCOS, these women may be at significant risk for progressive hepatic injury over the course of their lives. Many potential links between PCOS and NAFLD have been proposed, most notably IR and hyperandrogenemia. Further studies are needed to clarify the association between PCOS and NAFLD. In the interim, clinicians should be aware of this connection and consider screening for NAFLD in PCOS patients who have other metabolic risk factors. The optimal method of screening is unknown. However, measuring alanine aminotransferase and/or obtaining ultrasound on high-risk patients can be considered. First line treatment consists of lifestyle interventions and weight loss, with possible pharmacologic interventions in some cases.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the Western world comprising a spectrum of liver damage from fatty liver infiltration to end-stage liver disease, in patients without significant alcohol consumption. Increased prevalence of NAFLD has been reported in patients with polycystic ovary syndrome (PCOS), one of the most common endocrinopathies in premenopausal women, which has been redefined as a reproductive and metabolic disorder after the recognition of the important role of insulin resistance in the pathophysiology of the syndrome. Obesity, in particular central adiposity and insulin resistance are considered as the main factors related to NAFLD in PCOS. Moreover, existing data support that androgen excess, which is the main feature of PCOS and is interrelated to insulin resistance, may be an additional contributing factor to the development of NAFLD. Although the natural history of NAFLD remains unclear and hepatic steatosis seems to be a relatively benign condition in most patients, limited data imply that advanced stage of liver disease is possibly more frequent in obese PCOS patients with NAFLD. PCOS patients, particularly obese patients with features of the metabolic syndrome, should be submitted to screening for NAFLD comprising assessment of serum aminotransferase levels and of hepatic steatosis by abdominal ultrasound. Lifestyle modifications including diet, weight loss and exercise are the most appropriate initial therapeutic interventions for PCOS patients with NAFLD. When pharmacologic therapy is considered, metformin may be used, although currently there is no medical therapy of proven benefit for NAFLD. Long-term follow up studies are needed to clarify clinical implications and guide appropriate diagnostic evaluation, follow-up protocol and optimal treatment for PCOS patients with NAFLD.

Abstract
OBJECTIVE The increased standardized mortality ratio (SMR) from cardiovascular disease (CVD) in women with bipolar disorder (BD), relative to men with BD and individuals of both sexes in the general population, provides the impetus to identify factors that contribute to the differential association of obesity with BD in women. METHODS We conducted a selective PubMed search of English-language articles published from September 1990 to June 2012. The key search terms were bipolar disorder and metabolic syndrome cross-referenced with gender, sex, obesity, diabetes mellitus, hypertension, and dyslipidemia. The search was supplemented with a manual review of relevant article reference lists. Articles selected for review were based on author consensus, the use of a standardized experimental procedure, validated assessment measures, and overall manuscript quality. RESULTS It is amply documented that adults with BD are affected by the metabolic syndrome at a rate higher than the general population. Women with BD, when compared to men with BD and individuals of both sexes in the general population, have higher rates of abdominal obesity. The course and clinical presentation of BD manifest differently in men and women, wherein women exhibit a higher frequency of depression predominant illness, a later onset of BD, more seasonal variations in mood disturbance, and increased susceptibility to relapse. Phenomenological factors can be expanded to include differences in patterns of comorbidity between the sexes among patients with BD. Other factors that contribute to the increased risk for abdominal obesity in female individuals with BD include reproductive life events, anamnestic (e.g., sexual and/or physical abuse), lifestyle, and iatrogenic. CONCLUSIONS A confluence of factors broadly categorized as broad- and sex-based subserve the increased rate of obesity in women with BD. It remains a testable hypothesis that the increased abdominal obesity in women with BD mediates the increased SMR from CVD. A clinical recommendation that emerges from this review is amplified attention to the appearance, or history, of factors that conspire to increase obesity in female patients with BD.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age and is associated with various metabolic perturbations, in addition to chronic anovulation and factors related to androgen excess. In general, women live longer than men and develop cardiovascular disease at an older age. However, women with PCOS, as compared with age- and body mass index-matched women without the syndrome, appear to have a higher risk of insulin resistance, hyperinsulinemia, glucose intolerance, dyslipidemia, and an increased prothrombotic state, possibly resulting in a higher rate of type 2 diabetes mellitus, fatty liver disease, subclinical atherosclerosis, vascular dysfunction, and finally cardiovascular disease and mortality. Further alterations in PCOS include an increased prevalence of sleep apnea, as well as various changes in the secretion and/or function of adipokines, adipose tissue-derived proinflammatory factors and gut hormones, all of them with direct or indirect influences on the complex signaling network that regulates metabolism, insulin sensitivity, and energy homeostasis. Reviews on the cardiometabolic aspects of PCOS are rare, and our knowledge from recent studies is expanding rapidly. Therefore, it is the aim of the present review to discuss and to summarize the current knowledge, focusing on the alterations of cardiometabolic factors in women with PCOS. Further insight into this network of factors may facilitate finding therapeutic targets that should ameliorate not only ovarian dysfunction but also the various cardiometabolic alterations related to the syndrome.

Abstract
The aim of the presented study is to evaluate metabolic features in adolescents with polycystic ovary syndrome (PCOS) in comparison with age- and BMI-matched subjects. Forty-three adolescents with PCOS according to ESHRE criteria were prospectively evaluated and compared with 48 control subjects. Blood sampling was done in the early follicular phase of menstrual cycle, between 1st and 5th day, for plasma glucose, total and high-density lipoprotein (HDL)-cholesterol, triglycerides, insulin and C peptide. The diagnosis of metabolic syndrome was done according to IDF adolescent criteria. Adolescents with PCOS have increased low-density lipoprotein (LDL)-cholesterol (p < 0.002), decreased HDL-cholesterol (p <0.0007) and increased C peptide levels (p < 0.02) in comparison with healthy adolescents. Total cholesterol, triglycerides, fasting blood glucose, fasting insulin, HOMA-IR, waist-to-hip ratio, systolic and diastolic blood pressure did not differ between the groups. There was no difference when we compared the prevalence of adolescents with at least one feature of metabolic syndrome between PCOS (17 from 43) and healthy controls (27 from 48). In conclusion, adolescents with PCOS have less favourable blood lipid profiles with higher LDL-cholesterol and lower levels of HDL-cholesterol and are more insulin resistant than their healthy counterparts having higher fasting C peptide levels.
