Meta-Analysis
BACKGROUND
There is currently no concise systematic review or meta-analysis addressing cardio-metabolic risk factors in women experiencing infertility.
OBJECTIVES
To determine whether infertile women have higher levels of cardiovascular risk factors compared with fertile women.
SEARCH STRATEGY
We performed a systematic literature search using PubMed, Embase and CINAHL, Scopus and additional manual and bibliographic searches for relevant articles (end search date 6 November 2019).
SELECTION CRITERIA
We selected studies that compared cardio-metabolic risk factors in fertile and infertile women of reproductive age.
DATA COLLECTION AND ANALYSIS
At least two authors independently screened potentially eligible studies.
MAIN RESULTS
There was an increased presence of several cardio-metabolic risk factors in infertile women compared with fertile women. Infertile women had statistically significant higher body mass index (BMI), increased total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG) compared with fertile women. Fasting glucose, fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR) and mean arterial pressure were not found to be different between fertile and infertile women. A subgroup analysis revealed that TC, fasting glucose and fasting insulin were increased, and high-density lipoprotein was decreased only in women with polycystic ovarian syndrome compared with fertile women, whereas BMI, TG and LDL-C were statistically significantly increased in women with any indication of infertility compared with fertile women.
CONCLUSIONS
Infertile women have a higher level of cardio-metabolic risk factors compared with fertile women. This finding has clinical implications for infertile women in general, and those attempting to conceive through medically assisted reproduction.
TWEETABLE ABSTRACT
Infertile women appear to have a higher level of cardio-metabolic risk factors compared with fertile women.

Meta-Analysis
Association between hyperandrogenism and adverse pregnancy outcomes in patients with different polycystic ovary syndrome phenotypes undergoing fertilization/intracytoplasmic sperm injection: a systematic review and meta-analysis.
OBJECTIVE
To study the association between hyperandrogenism (HA) and adverse pregnancy outcomes in patients with different polycystic ovary syndrome phenotypes undergoing fertilization (IVF)/intracytoplasmic sperm injection (ICSI).
METHODS
We reviewed all eligible articles published up to October 2020 after searching in PubMed, Embase, Cochrane Library, Web of Science, Wanfang Data, and CNKI databases. The primary outcomes were the clinical pregnancy rate (CPR), miscarriage rate (MR), and live birth rate (LBR), whereas the secondary outcomes were the number of retrieved oocytes and endometrial thickness. Risk ratios (RRs) or mean differences with 95% confidence intervals (CIs) were calculated to estimate the HA impact on IVF/ICSI outcomes in patients with polycystic ovary syndrome (PCOS) phenotypes.
RESULTS
Of the 789 trials identified, nine retrospective studies involving 3037 patients with PCOS were included. Compared to the PCOS group with normal androgen levels, the PCOS group with HA exhibited increased MR (RR: 1.56, 95% CI: 1.13, 2.16); the CPR (RR: 0.88, 95% CI: 0.77, 1.01) and LBR (RR: 0.79, 95% CI: 0.55, 1.11) were not significantly different between these groups. Subgroup analysis revealed that the CPR was lower in the polycystic ovarian (PCO)-morphology + HA + oligo-anovulation (AO) group than in the PCO + AO group (RR: 0.81, 95% CI: 0.67, 0.99). Among Asians, the PCOS/HA group had increased MR (RR: 1.56, 95% CI: 1.06, 2.31) and showed thinner endometrial thickness. However, among Caucasians, no differences were observed between the two groups.
CONCLUSIONS
HA may have adverse effects on clinical pregnancy and miscarriage outcomes in different PCOS phenotypes, particularly among Asians.

Meta-Analysis
OBJECTIVE
To conduct a systematic review (SR) and meta-analysis (MA) on health-related quality-of-life (QoL) and associated factors among children/adolescents with congenital adrenal hyperplasia (CAH).
METHOD
Following registration in the PROSPERO International Prospective Register of Systematic Reviews(reg no: CRD42022313389), Google Scholar, PubMed, LILACS, Cochrane, and Scopus databases were searched up to March 5, 2022, using predefined search strategy/MESH terms to identify original studies describing/assessing self-reported/parent-reported health-related QoL in patients with CAH ≤21 years. Methodological quality was assessed by Newcastle-Ottawa Quality Assessment Scale (NOS), and heterogeneity by I2 statistics. MA assessed mean difference (MD) in QoL between children/adolescents with CAH and healthy children/adolescents.
RESULTS
Among 1308 publications, the 12 studies eligible for the SR (CAH n = 781) showed NOS scales of 3 to 7/9, and the 6 eligible for MA (CAH n = 227) showed moderate-considerable heterogeneity. MA showed that parent-reported psychosocial QoL (MD 9.9 [-12.6,7.3], P ≤ .001) {consisting of school (MD 7.4[-12.2, -2.5], P = .003), emotional (MD 5.6 [-10.2, -0.9], P = .02) and social domains (MD 4.3 [-8.1, -0.5], P = .03), and self-reported school domain QoL (MD 8.5 [-15.9, -1.2], P = .02) was lower in children/adolescents with CAH while parent-reported and self-reported physical QoL were similar to controls.Factors associated with lower QoL among children/ adolescents with CAH included poor disease control, poor medication compliance, and complications including hyperpigmentation, virilization, hypertension, hospital admission, and urinary incontinence.
CONCLUSION
Based on available data, children/adolescents with CAH had preserved physical QoL but impaired psychosocial QoL, especially in the school domain. Factors associated with lower QoL included poor disease control and disease/treatment-related complications. There is a need for further high-quality research that investigates the relationship between disease control, provision of psychosocial support, and improvement in QoL in children/adolescents with CAH.

BACKGROUND
Polycystic ovarian syndrome (PCOS) is one of the most prevalent endocrine disorders of women of reproductive age. Treatment plans for this chronic condition frequently include long-term use of a combination of medication and lifestyle interventions. However, treatment outcomes are dependent on adherence to treatment regimens. This study aimed to systematically review the literature for reported adherence to treatments for PCOS.
METHODS
A systematic search of Embase, Cochrane, PubMed, CINAHL, PsychINFO, SCOPUS, and International Pharmaceutical Abstracts from inception until January 2019 utilizing the terms PCOS, adherence, and patient compliance was conducted. A total of 179 possible articles were identified.
RESULTS
Fourteen articles reporting adherence data were included in the review. Self-report was the most commonly reported method of measuring adherence. Adherence to lifestyle interventions, such as prescribed diets and physical activity, was reported in ten studies and adherence to medications was reported in seven studies, with some reporting both.
CONCLUSIONS
Minimal data are available regarding factors associated with adherence in patients with PCOS. Diverse methods of adherence assessment are utilized. Future studies of PCOS treatments should effectively assess and report adherence data as it is essential to evaluating the effectiveness of PCOS treatments and is critically needed to guide clinician efforts to facilitate optimal outcomes for patients.

Polycystic ovary syndrome (PCOS) is a risk factor for dysglycemia, insulin resistance, and type 2 Diabetes Mellitus (T2DM). Inefficient energy oxidation, metabolic inflexibility, is a marker of blunted metabolism. We conducted a systematic review on metabolic inflexibility in women with PCOS. We searched MEDLINE, EMBASE and Cochrane central (inception-October 2018) for studies evaluating metabolic inflexibility and reporting on changes in Respiratory Quotient (ΔRQ). We extracted data and assessed quality using The Newcastle-Ottawa Scale. We included five prospective cohort studies (461 women). Three compared PCOS women to unaffected subjects, one to women with obesity or T2DM, and one to adolescent girls; all had medium quality. Three studies showed higher metabolic inflexibility in women with PCOS (ΔRQ range 0.05-0.098) compared to unaffected subjects. Women with PCOS had similar metabolic inflexibility compared to those with T2DM (ΔRQ 0.05 ± 0.03 vs 0.06 ± 0.04, = .98) and obesity ( = .06). Inflexibility was higher in hyperandrogenemic women with PCOS (ΔRQ 0.091 ± 0.060 vs 0.120 ± 0.010, = .014). ΔRQ was lower in PCOS women with insulin resistance vs those with normal insulin sensitivity (0.04 ± 0.02 vs. 0.07 ± 0.04, = .007). In conclusion, women with polycystic ovary syndrome appear to have higher metabolic inflexibility associated with hyperandrogenemia and insulin resistance.

Meta-Analysis
Polycystic ovary syndrome (PCOS) is an endocrine disorder that causes menstrual cycle irregularities and infertility. PCOS is diagnosed based on hyperandrogenism, polycystic ovarian morphology (PCOM), and an-/oligo-ovulation. Upregulation of anti-Müllerian hormone (AMH) in the serum of women with PCOS may be another suitable alternative diagnostic criterion for PCOM. However, previous meta-analyses have reported conflicting results due to the age-dependent decline in serum AMH levels. Therefore, we performed a meta-analysis to evaluate the threshold of AMH for the diagnosis of PCOS in adolescents and women in their early twenties. Fifteen trials were included in this meta-analysis. PCOS is diagnosed with either Rotterdam criteria, NIH, or AE-PCOS. AMH levels were significantly higher in adolescents with PCOS (weighted mean difference, 3.05; 95% confidence interval: 2.09-4.01) than in the control group. The cutoff values of AMH for the diagnosis of adolescent PCOS were 6.1, 6.26, 7.03, 7.11, 7.2, and 7.25 ng/mL in the studies that reported the usefulness of AMH levels. The summary receiver operating characteristic analysis of the diagnostic accuracy demonstrated that the specificity and sensitivity were 81% and 66.3%, respectively. Our meta-analysis demonstrates that AMH may be a useful diagnostic test for adolescent PCOS and, based on the previous studies included in the meta-analysis, its cutoff value was estimated to be 6-7 ng/mL.

Meta-Analysis
Several clinical studies showed that statins were potential to treat polycystic ovary syndrome (PCOS). Through comprehensive search PubMed, EMBASE, the Web of Science, BIOSIS, the ClinialTrails.gov, and the Cochrane Library database up to 14 Feb 2020, we identified the randomized controlled trials about the treatment of statins on hyperandrogenism in PCOS women, and performed a systematic review and meta-analysis. The quality of the included studies was assessed by the Cochrane risk of bias tool and the Jadda score. Subgroup analysis and sensitivity analysis were conducted to analyze the pooled results. Nine trials included 682 PCOS patients were identified. Statins showed a significant potential to reduce testosterone (SMD = -0.47; 95% CI, - 0.76-- 0.18; P = 0.002) and dehydroepiandrosterone (SMD = -0.51; 95% CI, - 0.97-- 0.05; P = 0.03) levels, compared to the control treatments. The cutaneous symptoms hirsutism (SMD = -0.61; 95% CI, - 1.13-- 0.10; P = 0.02) and acne (SMD = -0.92; 95% CI, - 1.49-- 0.34; P = 0.002) were significantly improved by statins in PCOS women. Subgroup analysis showed that the two types of statins, and the different control treatments as well, presented no significantly different effect on testosterone and dehydroepiandrosterone. Sensitivity analysis confirmed the stability of the findings from the meta-analysis. In conclusion, statin treatment could significantly reduce androgen levels and improve cutaneous manifestations of hyperandrogenism of PCOS.

OBJECTIVE
Lipoid congenital adrenal hyperplasia (LCAH) is caused by mutations in STAR. A systematic review of phenotype-genotype correlation and data on testicular histology in LCAH patients is unavailable. We aim to describe our experience and provide phenotype-genotype correlation. DESIGN, PATIENTS AND MEASUREMENTS: Retrospective review of three genetically proven LCAH patients from our centre and per-patient data analysis from a systematic review of 292 probands. The phenotypic subgroups of 46,XY were Group A (typical female genitalia), Group B (atypical genitalia) and Group C (typical male genitalia).
RESULTS
We report three new LCAH probands from India, all diagnosed post-infancy with preserved gonadal function and one novel variant. The systematic review reports 46,XY to 46,XX LCAH ratio of 1.1 (155:140). Patients with 46,XY LCAH in Group A were diagnosed in infancy (116/117) and had higher mineralocorticoid involvement than Group C (96.4% vs. 75%, p = 0.035), whereas Group C had preserved gonadal function. Hyperplastic adrenals are noted in ~60% of LCAH diagnosed with primary adrenal insufficiency in infancy. There was no report of gonadal germ cell cancer and rare reports of germ cell neoplasia in situ in adolescents, especially with intraabdominal gonads. Two-thirds of LCAH probands were East-Asian and 11/16 regional recurrent variants were from East Asia. There was minimal overlap between variants in Groups A (n = 55), B (n = 9) and C (n = 8). All nonsense and frameshift and most of the splice-site variants and deletion/insertions were present in Group A.
CONCLUSIONS
We report three new cases of LCAH from India. We propose a phenotype-derived genotypic classification of reported STAR variants in 46,XY LCAH.

Meta-Analysis
There is increasing evidence that steroid hormone levels and, especially, androgen levels are elevated in autism. An overactivity of 17, 20-lyase with a higher production of the testosterone precursors dehydroepiandrosterone (DHEA) and androstenedione/androstenediol seems especially present in autism. An encompassing literature analysis was performed, searching for altered androgens in children with autism and using preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Included were all studies published before 31 March 2021 found using the following electronic databases: PubMed, Google Scholar, Cochrane Library, Scopus, and TRIP. Eight studies with boys and three studies with girls where steroid hormone measurements were performed from either plasma, urine, or saliva were found and analyzed. Analyses were performed for DHEA(-S/-C), androstenedione/androstenediol, and testosterone. Effect sizes were calculated for each parameter between mean concentrations for children with autism versus healthy controls. Higher levels of androgens in autism were detected, with the majority of calculated effect sizes being larger than one. We found higher levels of the main testosterone precursors DHEA, androstenedione, and androstenediol, likely causing an additionally higher level of testosterone, and an increased 17, 20-lyase activity is therefore implied. Medications already used in PCOS such as metformin might be considered to treat hyperandrogenism in autism following further research.
