The Leydig Steroid Cell Tumor in a Postmenopausal Woman with Clinical and Biochemical Hyperandrogenism: A Case Report.

Leydig cell tumors (LCTs) refer to tumors of the stroma of the genital strand, which are found mainly in postmenopausal women. The diagnosis of LCTs in postmenopausal women is associated with specific difficulties and is based on the identification of hyperandrogenism with clinical manifestations of virilization, which has an erased picture in postmenopausal women. LCTs require differential diagnosis with other causes of hyperandrogenism. We present the clinical case of a 55-year-old Russian postmenopausal patient with LCTs of the right ovary, significantly increased levels of androgens, and rapidly progressive clinical signs of hyperandrogenism. The patient underwent laparoscopic bilateral salpingo-oophorectomy, and the androgen indices reached average values by the first and third month after surgery. This case demonstrates that LCTs are often benign with a good prognosis and normalization of the clinical and laboratory manifestations of hyperandrogenism after surgical treatment. The type of surgery performed (bilateral salpingo-oophorectomy rather than unilateral) is recommended as the treatment of choice for LCTs in postmenopausal patients.

PCOS Phenotype in Unselected Populations Study (P-PUP): Protocol for a Systematic Review and Defining PCOS Diagnostic Features with Pooled Individual Participant Data.

The diagnosis of polycystic ovary syndrome (PCOS) remains challenging due to limited data regarding normative cut-offs for the diagnostic features in different subpopulations. We aim to conduct a systematic review, build a comprehensive repository of de-identified individual participant data (IPD), and define normative ranges and diagnostic cut-offs for all PCOS diagnostic features. We will conduct a systematic search of MEDLINE and EMBASE databases for studies that assessed PCOS diagnostic features in unselected women. Two reviewers will assess eligibility and perform quality appraisal. Authors of included studies will be invited to contribute IPD. Primary variables include directly assessed modified Ferriman Gallwey (mFG) scores; menstrual cycle lengths; follicle number per ovary (FNPO), ovarian volume (OV), anti-Müllerian hormone (AMH); circulating androgens, including total testosterone (TT), free testosterone, bioavailable testosterone, free androgen index (FAI), androstenedione (A4), and dehydroepiandrosterone sulphate (DHEAS). Normative ranges and cut-offs will be defined using cluster analysis. Monash University Human Research Ethics Committee granted ethical approval (26938/0 1/12/2020), all IPD will be de-identified and primary studies have ethical approval from their institutional ethics committees. Findings will clarify distinction between PCOS and non-PCOS populations, and inform the update of the international evidence-based guidelines for the assessment and management of PCOS.

Comparison of two levonorgestrel-releasing intrauterine systems for the treatment of heavy menstrual bleeding: a randomised, controlled, phase 3 trial.

PURPOSE: To evaluate the levonorgestrel-releasing intrauterine system Donasert® (also known as Levosert®) compared with the reference product Mirena® for the alleviation of heavy menstrual bleeding (HMB). MATERIALS AND METHODS: A phase 3 multicentre, non-inferiority, active-controlled study in non-menopausal women with HMB (menstrual blood loss [MBL] ≥ 80 mL) as the primary symptom randomised to either Donasert® or Mirena® and followed for 6 months. MBL was evaluated using a validated, modified version of the Wyatt pictogram. RESULTS: Overall, 312 were randomised (158 to Donasert® and 154 to Mirena®). The mean (standard deviation) absolute change in MBL from baseline to 6 months in the per-protocol population (N = 300) was -130 (71.8) mL and -127 (67.3) mL in the Donasert® and Mirena® groups, respectively; non-inferiority of Donasert® was confirmed (p-value <0.0001). Successful treatment of HMB (MBL <80 mL) and a decrease to ≤50% of baseline MBL was achieved in 139/154 (90.3%) and 126/146 (86.3%) participants in the Donasert® and Mirena® groups, respectively and the between-treatment difference was non-significant. Most adverse events were mild in severity. Only two device expulsions occurred in the study and there were no uterine perforations. CONCLUSIONS: Donasert® has equivalent efficacy and safety during the first 6 months foralleviation of HMB compared to the reference device, Mirena®.

Criteria, phenotypes and prevalence of polycystic ovary syndrome.

Polycystic ovarian syndrome (PCOS) is known as one of the most frequent endocrine diseases in women worldwide. However, this term does not completely capture the diversity of clinical signs associated with this syndrome e.g., menstrual irregularity and clinical features of androgen excess, which are though commonplace in women with PCOS, they are not included under the definition of PCOS, limited to polycystic ovarian morphology (PCOM). Utilizing the most globally accepted criterion used today in the diagnosis of PCOS, the authors of this article review and discuss the historical and current context of evidence as well as their limitations. This review addresses the phenotypic approach and age-dependent aspects of PCOS in adolescents, adult and peri/postmenopausal women, as presented in the NIH (1990, 2012), Rotterdam (2003), AE-PCOS Society (2006) consensuses and in the latest evidence-based international guideline (2018). Global data on the epidemiology of PCOS, including prevalence and distribution of polycystic ovarian syndrome phenotypes, is also analyzed in the article. Lastly, the authors discuss the importance and current need to perform more epidemiological studies focused on PCOS.

Lipid peroxidation and antioxidant protection in girls with type 1 diabetes mellitus during reproductive system development.

BACKGROUND AND OBJECTIVE: Type 1 diabetes mellitus (T1D) is found worldwide and is regarded as one of the main risks to human health. The objective of this study was to determine the state of lipid peroxidation (LPO) and antioxidant protection in girls with T1D type considering the stages of reproductive system development. MATERIALS AND METHODS: This study enrolled 56 young girls with T1D and 60 healthy girls (control) matched by age. The study population was divided into 3 age groups: prepubertal, adolescent, and juvenile. The state of LPO and antioxidant system was assessed using the coefficient of oxidative stress that represented the ratio of LPO products to general antioxidative blood activity. Spectrophotometric and fluorometric methods were applied. RESULTS: The results of our study showed increased conjugated diene (CD) and thiobarbituric acid reactant (TBAR) concentrations as well as a decreased reduced glutathione level in prepubertal girls with T1D. Adolescent girls with T1D had a significantly greater CD level and juvenile girls with T1D had a significantly greater TBAR level and lower α-tocopherol concentration than girls in the control group. The greatest coefficient of oxidative stress (1.16) was observed in the prepubertal period. CONCLUSIONS: The prepubertal period is characterized by the most severe state of lipid peroxidation process-antioxidant protection.
