Adjunctive GnRH-a treatment attenuates depletion of ovarian reserve associated with cyclophosphamide therapy in premenopausal SLE patients

A Comprehensive Literature Review on Managing Systemic Lupus Erythematosus: Addressing Cardiovascular Disease Risk in Females and Its Autoimmune Disease Associations

This review aimed to evaluate the mechanism of premature cardiovascular disease (CVD) in systemic lupus erythematosus (SLE) patients, particularly in the female population, and emphasize the need for early management interventions; explore the association between SLE and two autoimmune diseases, myasthenia gravis (MG) and antiphospholipid antibody syndrome (APS), and their management strategies; and evaluate the effectiveness of pharmacological and non-pharmacological interventions in managing SLE, focusing on premenopausal females, females of childbearing age, and pregnant patients. We conducted a comprehensive literature review to achieve these objectives using various databases, including PubMed, Google Scholar, and Cochrane. The collected data were analyzed and synthesized to provide an evidence-based overview of SLE, its management strategies as an independent disease, and some disease associations. The treatment should be focused on remission, preventing organ damage, and improving the overall quality of life (QOL). Extensive emphasis should also be focused on diagnosing SLE and concurrent underlying secondary diseases timely and managing them appropriately.

Factors associated with fertility abnormalities in women with systemic lupus erythematosus: a systematic review and meta-analysis

BACKGROUND

Fertility is thought to be not affected in women with systemic lupus erythematosus (SLE), however disease-related factors, psychosocial effects of chronic disease, as well as medications exposure might impair gonadal function.

OBJECTIVE

This systematic literature review (SLR) aimed to explore clinical, hormonal, serological and treatment factors associated with fertility outcomes in women of childbearing age with SLE.

METHODS

This SLR was conducted following the Preferred Reporting Items for systematic reviews and Meta-analysis (PRISMA) statement. All articles available in English (1972 - 30th April 2021) in Pubmed, EMBASE, Scopus and Cochrane Library were screened. Study selection and data collection were performed by two independent reviewers. All data were extracted using a standardized template. The risk of bias of the included studies was assessed using the NIH risk-of-bias tool.

RESULTS

Of 789 abstracts evaluated, we included in this review 46 studies, of which 1 SLR, 16 cross-sectional studies, 18 cohort studies, 10 observational studies and 1 case-series, with data pertaining to 4704 patients (mean age 31.5 ± 3.7 years, disease duration 83.27 ± 38.3 months). Definitions of premature ovarian failure (POF) adopted in the studies varied in terms of the number of months of amenorrhea considered and the age of onset of amenorrhea. Clinical factors associated with the development of POF were older age at the time of initiation of therapy, and older age at the onset of SLE disease. Cyclophosphamide exposure (CYC) and its cumulative dose influenced gonadal function in SLE women, leading to amenorrhoea and POF, as reported in 19 studies. Mycophenolate, azathioprine, calcineurin inhibitors and steroids associated with a lower risk of POF compared to CYC. POF was less frequent in patients co-treated with CYC and gonadotropin-releasing hormone analogues (GnRH-a) compared with patients not receiving GnRH-a (risk ratio 0.798, 95%-CI [0.1417; 0.5525]). 11 studies evaluated the impact of damage accrual and disease activity on ovarian reserve with conflicting evidence. Finally, 18 studies investigated exposure to hormonal and serological factors and, among others, neither Anti-Müllerian Hormone nor anti-corpus luteum antibodies were associated with POF.

CONCLUSION

The strongest evidence regarding management factors associated with fertility in SLE women of childbearing age remains the treatment with CYC, as well as its cumulative dosage. Hormonal and serological factors appeared not to impact fertility outcomes, but they might be used as a surrogate of fertility, especially during the treatment with disease-specific drugs.

Pregnancy in patients with systemic lupus erythematosus after cyclophosphamide therapy

Systemic lupus erythematosus (SLE) often affects females of reproductive age and Cyclophosphamide, an alkylating agent leading to premature ovarian insufficiency (POF) and labelled category D for pregnancy is used as induction therapy for severe manifestations of lupus. There have been multiple case series reflecting variable outcomes of pregnancies after cyclophosphamide use for cancers and autoimmune diseases. With increasing maternal age, we have an increasing population of lupus patients who may wish to conceive after having received cyclophosphamide therapy. The objective of our study was to improve our understanding of the impact of cyclophosphamide exposure on fertility and pregnancy outcomes in patients with SLE.We retrospectively reviewed the charts of all patients who had received intravenous cyclophosphamide at our academic institute in the time period from 2000-2018 and identified 440 patients which included 157 female patients of reproductive age. There were 37 documented pregnancies after the cyclophosphamide infusion, of which 23 patients had successful outcomes; 4 elective abortion and 10 miscarriages. There were 17 patients who developed POF, of which 7 also had end stage renal disease. The average cumulative dose of cyclophosphamide in the patients who had successful pregnancy was 4080.37 mg compared to 2806.25 mg in those who had a miscarriage (p 0.164) and 5526.47 mg in those who developed POF (p 0.046). Using multiple regressions to evaluate risk factors impacting pregnancy outcomes, when taken as a set, the predictors including race, serological profile, exposure to steroids and Mycophenolate mofetil, age at cyclophosphamide infusion, age at pregnancy, and cumulative cyclophosphamide dose accounted for 46.29% of the variance in outcome of pregnancy (p 0.23) and 39.58% of the variance in development of premature ovarian failure (p 0.008). We noted statistical significance in the impact of maternal age at time of pregnancy (p 0.04) and duration of time between the last infusions to subsequent pregnancy (p 0.02) to pregnancy outcome.Our findings suggest that a longer time interval between the last cyclophosphamide infusion and subsequent pregnancy was favorable for a successful outcome and higher cumulative cyclophosphamide dose is more likely to be associated with premature ovarian failure.

2020 Chinese Guidelines for the Diagnosis and Treatment of Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that represents a prodigious challenge of diagnosis and treatment. In 2019, under the leadership of the Chinese Rheumatology Association, a multidisciplinary guideline development group was established to develop an evidence-based diagnosis and treatment guideline for patients with SLE in PR China. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence and the strength of recommendations. The guideline was reported following the Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist. In this guideline, we provided recommendations for SLE classification criteria, disease activity monitoring and assessment, medication administration and considerations for SLE patients with organs and systems involved, and management of special populations such as SLE patients in the setting of pregnancy. This guideline serves as an evidence-based tool for Chinese clinicians to diagnose and treat patients with SLE.

ESHRE guideline: female fertility preservation

STUDY QUESTION

What is the recommended management for women and transgender men with regards to fertility preservation (FP), based on the best available evidence in the literature?

SUMMARY ANSWER

The ESHRE Guideline on Female Fertility Preservation makes 78 recommendations on organization of care, information provision and support, pre-FP assessment, FP interventions and after treatment care. Ongoing developments in FP are also discussed.

WHAT IS KNOWN ALREADY

The field of FP has grown hugely in the last two decades, driven by the increasing recognition of the importance of potential loss of fertility as a significant effect of the treatment of cancer and other serious diseases, and the development of the enabling technologies of oocyte vitrification and ovarian tissue cryopreservation (OTC) for subsequent autografting. This has led to the widespread, though uneven, provision of FP for young women.

STUDY DESIGN SIZE DURATION

The guideline was developed according to the structured methodology for development of ESHRE guidelines. After formulation of key questions by a group of experts, literature searches and assessments were performed. Papers published up to 1 November 2019 and written in English were included in the review.

PARTICIPANTS/MATERIALS SETTING METHODS

Based on the collected evidence, recommendations were formulated and discussed until consensus was reached within the guideline group. A stakeholder review was organized after finalization of the draft. The final version was approved by the guideline group and the ESHRE Executive Committee.

MAIN RESULTS AND THE ROLE OF CHANCE

This guideline aims to help providers meet a growing demand for FP options by diverse groups of patients, including those diagnosed with cancer undergoing gonadotoxic treatments, with benign diseases undergoing gonadotoxic treatments or those with a genetic condition predisposing to premature ovarian insufficiency, transgender men (assigned female at birth), and women requesting oocyte cryopreservation for age-related fertility loss.The guideline makes 78 recommendations on information provision and support, pre-FP assessment, FP interventions and after treatment care, including 50 evidence-based recommendations-of which 31 were formulated as strong recommendations and 19 as weak-25 good practice points and 3 research only recommendations. Of the evidence-based recommendations, 1 was supported by high-quality evidence, 3 by moderate-quality evidence, 17 by low-quality evidence and 29 by very low-quality evidence. To support future research in the field of female FP, a list of research recommendations is provided.

LIMITATIONS REASONS FOR CAUTION

Most interventions included are not well studied in FP patients. As some interventions, e.g. oocyte and embryo cryopreservation, are well established for treatment of infertility, technical aspects, feasibility and outcomes can be extrapolated. For other interventions, such as OTC and IVM, more evidence is required, specifically pregnancy outcomes after applying these techniques for FP patients. Such future studies may require the current recommendations to be revised.

WIDER IMPLICATIONS OF THE FINDINGS

The guideline provides clinicians with clear advice on best practice in female FP, based on the best evidence currently available. In addition, a list of research recommendations is provided to stimulate further studies in FP.

STUDY FUNDING/COMPETING INTERESTS

The guideline was developed and funded by ESHRE, covering expenses associated with the guideline meetings, with the literature searches and with the dissemination of the guideline. The guideline group members did not receive payment.

Anti-Müllerian hormone in African-American women with systemic lupus erythematosus

OBJECTIVE

Women with SLE may experience ovarian insufficiency or dysfunction due to treatment or disease effects. Anti-Müllerian hormone (AMH), a marker of ovarian reserve, has been examined in small populations of women with SLE with conflicting results. To date, these studies have included very few African-American women, the racial/ethnic group at greatest risk of SLE.

METHODS

We enrolled African-American women aged 22-40 years diagnosed with SLE after age 17 from the Atlanta Metropolitan area. Women without SLE from the same area were recruited from a marketing list for comparison. AMH was measured in serum using the Ansh Labs assay (Webster, Texas, USA). We considered AMH levels <1.0 ng/mL and AMH <25th percentile of comparison women as separate dichotomous outcomes. Log-binomial regression models estimating prevalence ratios were adjusted for age, body mass index and hormonal contraception use in the previous year.

RESULTS

Our sample included 83 comparison women without SLE, 68 women with SLE and no history of cyclophosphamide (SLE/CYC-) and 11 women with SLE and a history of cyclophosphamide treatment (SLE/CYC+). SLE/CYC+ women had a greater prevalence of AMH <1.0 ng/mL compared with women without SLE (prevalence ratio (PR): 2.90, 95% CI: 1.29 to 6.51). SLE/CYC- women were also slightly more likely to have AMH <1.0 ng/mL (PR: 1.62, 95% CI: 0.93 to 2.82) than comparison women. Results were similar when considering AMH <25th percentile by age of comparison women.

CONCLUSIONS

Treatment with CYC is associated with low AMH in African-American women with SLE. SLE itself may also be associated with reduced AMH, but to a lesser extent.

A systematic review and meta-analysis of the gonadotoxic effects of cyclophosphamide and benefits of gonadotropin releasing hormone agonists (GnRHa) in women of child-bearing age with autoimmune rheumatic disease

Objectives: To systematically review risk of sustained amenorrhea with intravenous (IV) cyclophosphamide in autoimmune rheumatic disease (ARD), and evaluate efficacy of gonadotropin-releasing hormone agonists (GnRHa) to reduce this risk.Methods: Systematic search for papers reporting incidence of sustained amenorrhea ≥12 months in ARD following: IV cyclophosphamide; or GnRHa and IV cyclophosphamide compared to IV cyclophosphamide alone.Results: From 31 articles and 1388 patients (mean age 27.7 years) sustained amenorrhea occurred in 273 patients (19.7%). Of 56 patients (mean age range 23.9-25.6 years) receiving GnRHa and IV cyclophosphamide, and 37 controls (mean age range 25-30.1 years) given IV cyclophosphamide only, sustained amenorrhea occurred in 2/56 (3.6%) patients treated with GnRHa, compared to 15/37 (40.5%) controls. Pooled odds ratio of sustained amenorrhea with GnRHa and cyclophosphamide versus cyclophosphamide alone was 0.054 (95% CI 0.0115-0.2576 p < 0.001), corresponding to a number needed to treat of 2.7 (95% CI 1.955-4.388) and absolute risk reduction of 36.95% (95% CI 35.6-38.4%).Conclusion: Sustained amenorrhea with IV cyclophosphamide was observed in patients with ARD, especially with increasing age and cumulative doses >5 g. GnRHa reduced this risk and should be considered with IV cyclophosphamide in women of childbearing age with ARD.

Pregnancy and autoimmune diseases

Autoimmune diseases (AID) are more prevalent in women than in men, and pregnancy-related factors such as hormonal modulation and fetal microchimerism may influence the future risk of maternal AID. For women with AID, optimizing reproductive health requires a continuum of multidisciplinary care that initiates well before the desire for pregnancy is articulated. Family planning is essential so that pregnancy can be timed when disease is stable and to allow for appropriate medication adjustments. When contraception is used, the choice of method needs to take into consideration underlying disease and laboratory features. For females undergoing gonadotoxic therapy, options for preserving ovarian health and fertility warrant consideration, even among those who are not contemplating future pregnancy. Both maternal and fetal outcomes are optimized with multispecialty care as well as close monitoring during pregnancy and the postpartum period and when treatment regimens compatible with pregnancy are maintained to control underlying disease activity.

2019 update of the EULAR recommendations for the management of systemic lupus erythematosus

Our objective was to update the EULAR recommendations for the management of systemic lupus erythematosus (SLE), based on emerging new evidence. We performed a systematic literature review (01/2007–12/2017), followed by modified Delphi method, to form questions, elicit expert opinions and reach consensus. Treatment in SLE aims at remission or low disease activity and prevention of flares. Hydroxychloroquine is recommended in all patients with lupus, at a dose not exceeding 5 mg/kg real body weight. During chronic maintenance treatment, glucocorticoids (GC) should be minimised to less than 7.5 mg/day (prednisone equivalent) and, when possible, withdrawn. Appropriate initiation of immunomodulatory agents (methotrexate, azathioprine, mycophenolate) can expedite the tapering/discontinuation of GC. In persistently active or flaring extrarenal disease, add-on belimumab should be considered; rituximab (RTX) may be considered in organ-threatening, refractory disease. Updated specific recommendations are also provided for cutaneous, neuropsychiatric, haematological and renal disease. Patients with SLE should be assessed for their antiphospholipid antibody status, infectious and cardiovascular diseases risk profile and preventative strategies be tailored accordingly. The updated recommendations provide physicians and patients with updated consensus guidance on the management of SLE, combining evidence-base and expert-opinion.

Challenges of fertility preservation in non-oncological diseases

Clinicians should provide fertility counseling to all patients receiving gonadotoxic treatment. International scientific societies have mainly focused on oncological patients, and fewer efforts have been made to apply these recommendations to women diagnosed with benign disease (eg benign hematological diseases, autoimmune diseases, and gynecological or genetic disorders). However, these indications account for 8%-13% of the demand for fertility preservation. The risk of premature ovarian failure due to treatment, or to the disease itself, can be considered fairly high for many young women. Counseling and adequate management of these women require particular attention due to the severe health conditions that are associated with some of these diseases. In this review, we address specific issues related to providing adequate fertility counseling and management for women who have been diagnosed with the major non-oncological indications, based on the literature and on our clinical experience.

Fertility and reproductive care in chronic kidney disease

In both women and men, chronic kidney disease (CKD) is associated with decreased fertility. Though a multitude of factors contribute to the reduction in fertility in this population, progressively impaired function of the hypothalamic-pituitary-gonadal axis appears to play a key role in the pathophysiology. There is limited research on strategies to manage infertility in the CKD population, but intensive hemodialysis, kidney transplantation, medication management and assisted reproductive technologies (ART) have all been proposed. Though fertility and reproductive care are reported as important elements of care by CKD patients themselves, few nephrology clinicians routinely address fertility and reproductive care in clinical interactions. Globally, the average age of parenthood is increasing, with concurrent growth and expansion in the use of ART. Coupled with an increasing prevalence of CKD in women and men of reproductive age, the importance of understanding fertility and reproductive technologies in this population is highlighted. This review endeavors to explore the female and male factors that affect fertility in the CKD population, as well as the evidence supporting strategies for reproductive care.

Gonadotropin-Releasing Hormone Analogs for Gonadal Protection During Gonadotoxic Chemotherapy: A Systematic Review and Meta-Analysis

OBJECTIVE

A systematic review and meta-analysis was conducted to investigate whether gonadotropin-releasing hormone analogs (GnRHa) have a protective role in women treated with alkylating agents.

DATA SOURCES

Major databases (PubMED, EMBASE, Cochrane Central Register of Controlled Trials), systematic snowballing, and trial registries were screened from the inception dates until September 2017.

METHODS AND STUDY SELECTION

Comparative studies involving reproductive-aged women undergoing chemotherapy with or without coadministration of GnRHa were included. Spontaneous menstrual resumption was assessed as a main outcome. Statistical analyses were performed with STATA 14.2 statistical software. Effect estimates were presented as risk ratios (RR) with 95% confidence intervals (CIs).

RESULTS

The literature search yielded 25 436 citations and 84 papers were assessed in full text. Eighteen studies (11 randomized controlled trials [RCTs] and 7 cohort studies) published between 1987 and 2015 were included in the analysis, revealing a significant protective effect of GnRHa (n = 1043; RR:1.38; 95% CI: 1.18-1.63) although with high heterogeneity (I² = 83.3%). Subgroup analyses revealed a significant benefit of GnRHa cotreatment both in RCTs and in cohort studies. Statistical significance was found in all subgroups by the underlying disease, that is, hematological malignancies, autoimmune diseases, and breast cancer. Sensitivity analyses in GnRH agonist-treated patients, in patients younger than 40 years old, and in patients without supradiaphragmatic radiotherapy also revealed a significant benefit of GnRHa cotreatment.

CONCLUSION

Our results indicate that concurrent GnRHa administration is an effective method to decrease gonadotoxicity of alkylating agents. The presence of low-quality evidence favoring gonadoprotective effect requires a strong recommendation for offering GnRHa coadministration to young women who are to undergo gonadotoxic chemotherapy.

CAPSULE

The present systematic review and meta-analysis shows a significant gonadoprotective effect of gonadotropin-releasing hormone analogs in women treated with alkylating agents.

Fertility, Contraception, and Novel Reproductive Technologies in Chronic Kidney Disease

Chronic kidney disease (CKD) affects hypothalamic-pituitary-gonadal axis function, leading to menstrual abnormalities, sexual dysfunction, functional menopause, and loss of fertility. Pregnancy in a patient with CKD is associated with a higher risk of complications to both the mother and the fetus, highlighting the importance of contraceptive counseling at all stages of CKD. There has been limited research on the safety and efficacy of different contraceptive methods in the CKD population, and it is important to tailor the choice of contraception to the patient's lifestyle and comorbidity status. Cyclophosphamide is a commonly used immunosuppressive agent that impairs fertility in a dose-dependent fashion, with greater impact in older women of child-bearing age. Strategies to reduce the impact of cyclophosphamide on ovarian reserve as well as fertility preservation technologies are options to consider when treating immune-mediated CKD. A multidisciplinary approach in counseling the woman with CKD who wishes to contemplate or avoid pregnancy is necessary to optimize outcomes. Further research in this important area is required.

Practical recommendations for fertility preservation in women by the FertiPROTEKT network. Part I: Indications for fertility preservation

Purpose

Most guidelines about fertility preservation are predominantly focused on scientific evidence, but are less practically orientated. Therefore, practically oriented recommendations are needed to support the clinician in daily practice.

Methods

A selective literature search was performed based on the clinical and scientific experience of the authors, focussing on the most relevant diseases and gynaecological cancers. This article (Part I) provides information on topics that are essential for the fertility preservation indication, such as disease prognosis, disease therapy and its associated risks to fertility, recommending disease-specific fertility preservation measures. Part II specifically focusses on fertility preservation techniques.

Results

In breast cancer patients, fertility preservation such as ovarian tissue and oocyte cryopreservation is especially recommended in low-stage cancer and in women < 35 years of age. In Hodgkin’s lymphoma, the indication is mainly based on the chemotherapy regime as some therapies have very low, others very high gonadotoxicity. In borderline ovarian tumours, preservation of fertility usually is achieved through fertility sparing surgery, ovarian stimulation may also be considered. In cervical cancer, endometrial cancer, rheumatic diseases and other malignancies such as Ewing sarcoma, colorectal carcinoma, non-Hodgkin lymphoma, leukaemia etc., several other factors must be considered to enable an individual, stage-dependent decision.

Conclusion

The decision for or against fertility preservation depends on the prognosis, the risks to fertility and individual factors such as prospective family planning.

Menopause and Rheumatic Disease

Menopause occurs naturally in women at about 50 years of age. There is a wealth of data concerning the relationship of menopause to systemic lupus erythematosus, rheumatoid arthritis, and osteoarthritis; there are limited data concerning other rheumatic diseases. Age at menopause may affect the risk and course of rheumatic diseases. Osteoporosis, an integral part of inflammatory rheumatic diseases, is made worse by menopause. Hormone replacement therapy has been studied; its effects vary depending on the disease and even different manifestations within the same disease. Cyclophosphamide can induce early menopause, but there is underlying decreased ovarian reserve in rheumatic diseases.

Infertility - Prevention and Management

Infertility and subfertility, menstrual irregularities, and decreased parity may occur in women with autoimmune diseases due to multiple factors, including underlying inflammatory disease, gonadotoxic medications, and psychosocial issues related to living with chronic disease. Awareness of these factors, as well as validation and support of patients confronting reproductive challenges, is important for providing comprehensive care to these women. An understanding of the expanding options for fertility preservation strategies during gonadotoxic medications is essential. Referral to a reproductive endocrinology clinic is indicated in this patient population.

Pregnancy and autoimmune connective tissue diseases

Autoimmune connective tissue diseases predominantly affect women and often occur during the reproductive years. Thus, specialized issues in pregnancy planning and management are commonly encountered in this patient population. This chapter provides a current overview of pregnancy as a risk factor for onset of autoimmune disease, considerations related to the course of pregnancy in several autoimmune connective tissue diseases, and disease management and medication issues before pregnancy, during pregnancy, and in the postpartum period. A major theme that has emerged across these inflammatory diseases is that active maternal disease during pregnancy is associated with adverse pregnancy outcomes, and that maternal and fetal health can be optimized when conception is planned during times of inactive disease and through maintaining treatment regimens compatible with pregnancy.

Prevalence of premature ovarian failure in patients with systemic lupus erythematosus

OBJECTIVE

To estimate the prevalence of premature ovarian failure (POF) and its associated factors in patients with systemic lupus erythematosus (SLE).

METHODS

Cross-sectional study including consecutive SLE women <60 years of age attending a rheumatology clinic. A face-to-face interview was undertaken to obtain demographic, gynaecological and lupus characteristics. Additional rheumatologic and endocrine data were retrieved from patients' medical records. POF prevalence was estimated in the study sample and in a subgroup of patients aged <40 years at interview. Associations between POF and selected variables were assessed by logistic regression analyses.

RESULTS

A total of 961 patients were analysed. Prevalence of POF, secondary amenorrhea of known cause, menopause and hysterectomy were 5.4%, 0.8%, 7.8% and 4.4%, respectively. In 674 (70%) patients who had not been exposed to cyclophosphamide (CYC) the prevalence of POF was 0.6%. Disease activity over time (OR 1.4 (CI 95% 1.0-1.8, p < 0.05)) and CYC treatment (OR 5.9 (CI 95% 1.8-18.8, p < 0.01)) were associated with higher prevalence. Association between POF and endocrine autoimmune diseases was not found.

CONCLUSIONS

In the absence of CYC treatment, the prevalence of POF in lupus patients is consistent with that reported in the general population. The existence of autoimmune processes at the ovary seems unlikely in most lupus patients.

Are sirtuins markers of ovarian aging?

Sirtuins, a family of nicotinamide adenine dinucleotide (NAD)-dependent deacetylases that play diverse roles in regulating metabolism, cell proliferation, and genome stability, have been implicated in mammalian aging and age-related diseases, including cancers, metabolic disorders, and neurodegenerative diseases. Ovarian aging is thought to be characterized by a gradual decrease in both the number of follicles and the quality of oocytes. Ovarian reserve is indicated by the number of primordial follicles. In this study, ovarian reserve was assessed in mice of different ages and mice subjected to caloric restriction (CR) and chemotherapy (2 commonly used models for ovarian aging research) by counting primordial follicles and determining the expression levels of SIRT1, SIRT3, and SIRT6 to explore the relationship between ovarian function and sirtuin expression. A gradual decline in the number of follicles (especially primordial follicles) was observed in aging mice and mice subjected to chemotherapy. Histological analysis showed that CR mice displayed a significantly greater number of primordial follicles and less atretic follicles. Western blot analysis indicated that expression levels of SIRT1, SIRT3, and SIRT6 were significantly decreased in the ovaries of aged mice and mice treated with chemotherapy, but increased in CR mice. SIRT1, SIRT3, and SIRT6 all showed a significantly positive correlation with the numbers of primordial follicles (r(2)=0.6399, P<0.0001; r(2)=0.5445, P<0.001; and r(2)=0.4956, P<0.0001, respectively). These results indicate that SIRT1, SIRT3 and SIRT6 are closely related to ovarian reserve, and suggest that these sirtuins may be markers of ovarian aging.

Adjuvant hormonal therapy and fertility preservation in premenopausal breast cancer: a survey among Italian oncologists

BACKGROUND

Increasing age of first pregnancy among Italian women with premenopausal breast cancer makes adjuvant hormonal therapy a hot topic, justifying a survey on the therapeutic approach of Italian oncologists.

MATERIALS & METHODS

From April to July 2012, an 11-item electronic questionnaire was submitted to Italian oncologists and 611 out of 974 invited filled questionnaires were collected from all over Italy.

RESULTS

In total, 97.7% of patients aged <40 years needing only hormonal therapy would receive both tamoxifen and luteinizing hormone-releasing hormone agonists (LHRHa); 2.3% tamoxifen or LHRHa alone. For the majority of oncologists LHRHa was also the preferred choice to preserving fertility.

CONCLUSION

Results are rather consistent with major guidelines but with a greater use of LHRHa and aromatase inhibitor.

[In vitro fertilization and systemic lupus erythematosus or antiphospholipid syndrome: An update]

Fertility is not impaired in systemic lupus erythematosus or antiphospholipid syndrome, but, similarly to the general population, these patients may undergo in vitro fertilization. This type of treatment increases the risk of lupus flare, thrombosis, and ovarian hyperstimulation syndrome. This review will focus on in vitro fertilization in systemic lupus erythematosus or antiphospholipid syndrome. Literature data are relatively scant with only 3 reported studies. The first one included 17 patients and 63 cycles of induction ovulation/in vitro fertilization leading to 25 % of lupus flare, no thrombosis, and 3 % of ovarian hyperstimulation syndrome. The second study included 10 patients and 40 cycles of in vitro fertilization showing 31 % of lupus flare, no thrombosis and no ovarian hyperstimulation syndrome. The last one included 34 patients and 83 procedures of in vitro fertilization leading to 8 % of flares, 5 % of thrombosis and no ovarian hyperstimulation syndrome. Interestingly, in this last study, half of the complications were explained by poor adherence to treatment. These data are reassuring but it is important to remember that in vitro fertilization should be scheduled and carefully supervised in the same way as the high-risk pregnancies occurring in these patients.

Anti-Müllerian hormone in reproductive age women with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune systemic and chronic disease. Fertility in SLE patients is considered normal; factors that have been associated in these patients with ovarian failure are: disease activity, autoantibodies, and the use of cytotoxic agents. The anti-Müllerian hormone (AMH) is a marker that helps to determine the follicular reserve.

OBJECTIVE

Determinate the objective was to determine AMH levels in women of reproductive age with SLE.

MATERIAL AND METHODS

We included 65 women with SLE classified according to the 1997 ACR criteria, 18- to 40-years old. We obtained demographic, clinical, obstetric, and gynecological characteristics as well as serum levels of AMH. We performed a bivariate analysis among patients with low ovarian reserve and those with normal ovarian reserve. We also performed a correlation analysis between activity and damage index and between the cumulative cyclophosphamide dose and AMH levels.

RESULTS

We found a median of serum AMH in SLE patients of .61 ng/mL. The prevalence of low ovarian reserve in our study was 3.07%. We found a median MEX-SLEDAI score of 1 point and the median SLICC score was 2 points. Twenty-five patients (38.4%) had used cyclophosphamide and their cumulative average dose was 7.5 grams.

CONCLUSIONS

We found a median of AMH of .61 ng/mL in our population. The prevalence of low ovarian reserve in SLE patients was 3.07%. We did not find a correlation between AMH levels, the use of cyclophosphamide, and disease activity.

Study of anti-Müllerian hormone and its relation to the subsequent probability of pregnancy in 112 patients with systemic lupus erythematosus, exposed or not to cyclophosphamide

CONTEXT

Cyclophosphamide is used for renal and major extrarenal involvement in systemic lupus erythematosus (SLE) and is associated with a risk of premature ovarian failure. There are no data available about the relation between anti-Müllerian hormone (AMH) serum levels and the probability of subsequent pregnancy in SLE patients.

OBJECTIVE

We analyzed AMH levels and the probability of pregnancy in SLE women exposed to cyclophosphamide.

DESIGN AND SETTING

We conducted a matched cohort study in referral centers for SLE.

PATIENTS

Fifty-six cyclophosphamide-exposed SLE women younger than 40 years of age and 56 control SLE women matched for age within 6 months participated in the study.

MAIN OUTCOME MEASURES

AMH was measured in samples from the PLUS study (ClinicalTrials.gov no. NCT00413361). All patients were interviewed in May 2012 regarding their obstetric status.

RESULTS

The mean age ± SD of the 112 patients was 31.6 ± 5.8 years. The mean AMH level was low (1.21 ± 1.01 ng/mL) and was significantly lower in patients exposed to cyclophosphamide (P = .03) and in patients older than 30 years (P = .02). During a median follow-up (interval between sampling and the interview) period of 4.2 (range, 2.5-4.8) years, 38 patients sought to become pregnant, and 32 (84.2%) succeeded. In the univariate analysis, the risk of failure was associated with cumulative cyclophosphamide dose (P = .007) and older age (P = .02), but not with AMH.

CONCLUSION

We confirmed that AMH levels are low in SLE patients and decrease significantly with age and cyclophosphamide exposure. Nonetheless, the risk of failure to conceive was low and was predicted by cyclophosphamide exposure and age, but not by AMH levels.

Fertility preservation in gynecological cancers

For cancers of reproductive system in women, fertility preservation is complex. Fertility is also affected by therapies, however prevention is possible. Radiotherapy affects gonads, uterus, and subsequent pregnancy outcomes in all ages. However, degree and damage depend on dose, irradiation field, and age at the time of exposure. Ovarian transposition is considered if ovarian involvement is unlikely. Gonadotoxic effects of chemotherapy are related to agent's type, cumulative doses, age, and ovarian reserve. Some agents are highly toxic. Rendering follicular development quiescent by suppression of gonadotropins does reduce the ovarian damage. Simple or radical trachelectomy can be used in early cervical cancer. Fertility saving surgery is possible only in early stage low grade epithelial cancers of the ovary, however, in germ cell tumors even in advanced stages it may be possible to preserve fertility. There are no standard recommendations for endometrial cancer. Embryo, oocyte, and ovarian tissue cryopreservation are possible. The human embryo is very resistant to damage. In view of these possibilities, it is advocated that attention to long term health and quality of life in gonadotoxic therapy must be incorporated into plans as early as possible.

The impact of cyclophosphamide on menstruation and pregnancy in women with rheumatologic disease

Background

While cyclophosphamide (CYC) can save the life of a young woman with severe rheumatologic disease, it may lead to the long-term side-effects of infertility and premature menopause. We compared the reproductive health histories of young women with rheumatologic disease with and without prior CYC exposure to identify the impact of this medication on this important component of health.

Methods

This research includes a case-series study of women diagnosed with SLE, vasculitis, and scleroderma prior to age 35. Each patient completed a questionnaire about desired childbearing, menstrual regularity, infertility, and pregnancy history. Women with prior CYC therapy were queried about the use of gonadotropin-releasing hormone agonists (GnRH-a) for fertility preservation. The responses to this questionnaire were compared for women with and without CYC exposure.

Results

Of the 43 participants, 23 had prior CYC exposure and 20 were CYC naïve. The current age of these groups was similar (average age 32), but women with prior CYC were four years younger at diagnosis than women without CYC. More women with prior CYC had cessation of menses in the year prior to the study (30.4% vs 0%, p < 0.05). Of the women with prior CYC exposure, those with loss of menses were older at study enrollment, older at CYC treatment, and had a higher cumulative CYC dose than those with preserved menstruation. While more women with GnRH-a co-therapy during CYC had maintained menses, this difference did not reach statistical significance. Women with prior CYC without GnRH-a co-therapy had a higher frequency of nulliparity and had greater trouble conceiving than women with GnRH-a co-therapy. Few pregnancies were conceived following CYC exposure and all resulted in elective termination, miscarriage, or preterm birth.

Conclusion

In this cohort of young women with rheumatologic disease, more women with prior CYC than without had amenorrhea, nulliparity, and infertility. GnRH-a co-therapy may prevent these adverse effects of CYC.

Ovarian Damage During chemotherapy in Autoimmune Diseases: Broad Health Implications beyond Fertility

Women with autoimmune diseases such as lupus, scleroderma, and vasculitis receiving cyclophosphamide for severe disease manifestations risk primary ovarian insufficiency(POI) due to gonadotoxicity of this therapy. In addition to loss of reproductive potential, POI is associated with increased risk of morbidity and mortality. Practitioners caring for women requiring gonadotoxic therapies should be familiar with long-term health implications of POI and strategies for ovarian preservation. Accumulating evidence supports the effectiveness of adjunctive gonadotropin releasing hormone analog (GnRH-a) for ovarian protection during gonadotoxic therapy in cancer and autoimmune populations. GnRH-a is less costly and invasive than assisted reproductive technologies used for achievement of future pregnancies, but is not Food and Drug Administration approved for ovarian preservation. This review focuses on POI comorbidities and strategies for mitigation of related sequelae, which can accumulate over decades of hypoesteogenism. These issues are arguably more pronounced for women with chronic autoimmune diseases, in whom superimposed POI further heightens risks of cardiovascular disease and osteoporosis. Therefore, even if future pregnancy is not desired, ovarian protection during gonadotoxic therapy should be a major goal of disease management.

Preservation of ovarian function and fertility despite gonadotoxic chemotherapy

The author aims to review the various strategies and avenues for fertility preservation despite gonadotoxic chemotherapy in young women. The recent increase in the survival of young patients has increased the worldwide attempts toward fertility preservation. The currently utilized methods are sperm cryopreservation and banking in male patients, and cryopreservation of embryos, unfertilized oocytes and ovarian tissue, as well as administration of gonadotropin-releasing hormone agonists (GnRH-a) before and during the gonadotoxic chemotherapy in young female patients. For those patients in whom pelvic irradiation is planned, ovariopexy is suggested. Since none of the suggested methods are ideal and none guarantees future fertility, a combination of several methods may optimize patients' chance of fertility preservation. GnRH-a co-treatment may reduce ovarian damage significantly in female patients treated with gonadotoxic chemotherapy. GnRH-a should be considered for women of reproductive age receiving gonadotoxic chemotherapy in addition to assisted reproduction and cryopreservation of embryos, oocytes and ovarian tissue.
