RESUMO

Gonadal dysfunction and reduced fertility are clinical manifestations well described in patients with Fanconi anemia (FA) and following hematopoietic stem cell transplantation (HSCT). It is difficult to differentiate gonadal dysfunction from the primary disease itself or from HSCT procedures. Therefore, it is important to manage expectations about gonadal failure and infertility for all patients with FA, regardless of the HSCT status. We performed a retrospective analysis of 98 pediatric patients with FA who were transplanted between July 1990 and June 2020 to evaluate the incidence of gonadal dysfunction in female and male patients with FA. New-onset premature ovarian insufficiency (POI) was diagnosed in a total of 30 (52.6%) patients. Follicle-stimulating hormone and luteinizing hormone levels were increased in patients diagnosed with POI. Anti- Mullerian hormone levels declined in POI patients after HSCT (r2=0.21; P=0.001). Twenty (48.8%) male patients were diagnosed with testicular failure. Follicle-stimulating hormone levels increased after HSCT even in patients without testicular failure (r2=0.17; P=0.005). Inhibin B levels decreased over time after HSCT in patients with testicular failure (r2=0.14; P=0.001). These data indicate brisk decline in already impaired gonadal function in transplanted children with FA.

RESUMO

OBJECTIVE: To determine the patient characteristics associated with pursuing fertility preservation (FP) before gonadotoxic therapy in a pediatric, adolescent and young adult patient population. METHODS: This is a retrospective cohort study of patient data at Cincinnati Children's Hospital Medical Center. Demographics, clinical diagnoses, and treatment characteristics were compared between participants that selected FP versus those that declined. Variables were analyzed separately for males and females by logistic regression. RESULTS: Patients with a hematologic cancer were less likely to be eligible for preservation: 53.9% of ineligible males, P <0.001, and 51.8% of ineligible females, P <0.0001. Among patients who were candidates for FP, those receiving high-risk therapy were more likely to elect for FP (65.3% males, P <0.0001, and 87.5% of females, P <0.0001). Pubertal males were more likely to undergo preservation than prepubertal males (70.5% vs. 29.5%, P <0.0001; however, this trend was not demonstrated among female patients. In both males and females, race, ethnicity, religion, primary language, and insurance status were not shown to be statistically significant factors in predicting utilization of FP. CONCLUSION: Risk of infertility, type of cancer, and developmental status influenced decisions on pursuing FP in pediatric, adolescent and young adult patients facing iatrogenic infertility.

RESUMO

There is a critical need to engage adolescents and young adults (AYAs) with cancer in conversations regarding "safer" sexual activity during treatment. Many providers, however, report lacking the knowledge and/or tools to engage in these discussions. This article describes the experience of one pediatric institution in assessing and addressing provider barriers to safer sexual activity discussions among AYAs with cancer. Feedback from patients and providers resulted in an educational handout detailing recommendations regarding safer sex practices for AYAs with cancer. Handout adoption, acceptability, appropriateness, and feasibility are described alongside barriers to assist other institutions seeking to develop similar interventions.

RESUMO

CONTEXT: Controversy exists regarding if and how body mass index (BMI) impacts antimüllerian hormone (AMH) in women with and without polycystic ovary syndrome (PCOS). Understanding the BMI-AMH relationship has critical implications for clinical interpretation of laboratory values and could illuminate underlying ovarian physiology. OBJECTIVE: To test the hypotheses that (1) BMI is associated with reduced AMH in PCOS and ovulatory controls (OVAs) and (2) the reduction in AMH is not accounted for by dilutional effects. DESIGN/SETTING: Multicenter cohort. PARTICIPANTS: Women aged 25 to 40 years from 2 clinical populations: 640 with PCOS, 921 women as OVAs. MAIN OUTCOME MEASURES: Ovarian reserve indices: AMH, antral follicle count (AFC), and AMH to AFC ratio (AMH/AFC) as a marker of per-follicle AMH production. RESULTS: In both cohorts, increasing BMI and waist circumference were associated with reductions in AMH and AMH/AFC, after adjusting for age, race, smoking, and site in multivariate regression models. Increasing BMI was associated with reduced AFC in PCOS but not OVAs. Body surface area (BSA), which unlike BMI is strongly proportional to plasma volume, was added to investigate a potential dilutive effect of body size on AMH concentrations. After controlling for BSA, BMI retained independent associations with AMH in both cohorts; BSA no longer associated with AMH. CONCLUSIONS: In an adjusted analysis, BMI, but not BSA, was associated with reduced AMH; these data do not support a role for hemodilution in mediating the relationship between increased body size and reduced AMH. Decreased AMH production by the follicle unit may be responsible for reduced AMH with increasing BMI.

RESUMO

Impairment of fertility and sexual/reproductive health are common after oncologic therapy, and are known to have negative impacts on romantic relationships and psychosocial well-being among childhood cancer survivors. The Pediatric Initiative Network (PIN) is an international, multidisciplinary group of providers within the Oncofertility Consortium dedicated to preserving and protecting the fertility of children and adolescents at risk for infertility due to medical conditions or treatments. The PIN and its Best Practices and Research committees meet virtually throughout the year, with one annual in-person meeting. The purpose of this "proceedings" is to highlight key discussion points from the annual PIN meeting which took place on November 11, 2019, to 1) provide a context for pediatric groups across the country on what oncofertility programs are currently doing and why, and 2) inform stakeholders of past, present and future initiatives that may be of value to them and the patient populations they serve.

RESUMO

CONTEXT: The relationship between reproductive and cardiometabolic aging is unclear. It is unknown if the relationship differs across different clinical populations. OBJECTIVE: To determine whether markers of ovarian reserve are associated with cardiometabolic risk in reproductive aged women with unexplained infertility (UI), polycystic ovary syndrome (PCOS), and regularly cycling women (OVA). DESIGN AND SETTING: Cross-sectional data from 8 US-based academic centers. PARTICIPANTS: Women aged 25-40 from 3 clinical populations: 870 with UI, 640 with PCOS, and 921 community-based OVA. MAIN OUTCOME MEASURES: Multivariable linear regression models were used to relate anti-mullerian hormone (AMH) and antral follicle count with cardiometabolic parameters including body mass index (BMI), waist circumference (WC), fasting glucose and insulin, homeostasis model assessment-insulin resistance (HOMA-IR), lipids, and C-reactive protein. RESULTS: In age and study site-adjusted models, AMH inversely related to BMI in the UI and OVA groups (P = 0.02 and P < 0.001). Among women with PCOS, AMH inversely related to BMI (P < 0.001), and also to WC (P < 0.001), fasting insulin (P < 0.01), HOMA-IR (P < 0.01), triglycerides (P = 0.04), and C-reactive protein (P < 0.001) and directly related to higher total (P = 0.02), low-density lipoprotein (P < 0.01), and high-density lipoprotein cholesterol (P < 0.01). In OVA, AMH also varied inversely with WC (P < 0.001), fasting insulin (P = 0.02), and HOMA-IR (P = 0.02). Adjustment for BMI eliminated associations in the OVA group but in PCOS, the relationship of AMH to total (P = 0.03) and low-density lipoprotein cholesterol (P = 0.003) remained. CONCLUSION: Associations observed between AMH and cardiometabolic indices are largely explained by BMI in women with and without PCOS. (J Clin Endocrinol Metab XX: 0-0, 2019).

RESUMO

Endometriosis currently affects ~5.5 million reproductive-aged women in the U.S. with symptoms such as painful periods (dysmenorrhea), chronic pelvic pain, pain with intercourse (dyspareunia), and infertility. It is defined as the presence of endometrial tissue outside the uterine cavity and is found predominately attached to sites within the peritoneal cavity. Diagnosis for endometriosis is solely made through surgery as no consistent biomarkers for disease diagnosis exist. There is no cure for endometriosis and treatments only target symptoms and not the underlying mechanism(s) of disease. The nature of individual predisposing factors or inherent defects in the endometrium, immune system, and/or peritoneal cavity of women with endometriosis remains unclear. The literature over the last 5 years (2010-2015) has advanced our critical knowledge related to hormones, hormone receptors, immune dysregulation, hormonal treatments, and the transformation of endometriosis to ovarian cancer. In this review, we cover the aforementioned topics with the goal of providing the reader an overview and related references for further study to highlight the progress made in endometriosis research, while concluding with critical areas of endometriosis research that are urgently needed.
