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

NSAID exposure delays time-to-pregnancy in patients with spondyloarthritis: an analysis of the GR2 prospective cohort

BACKGROUND

The impact of disease activity and treatment on fertility outcomes in patients with spondyloarthritis (SpA) has been little explored. This study aimed to describe median time to pregnancy (TTP) in women with SpA and the factors influencing TTP in this population.

METHODS

This prospective observational multicentre (63 centres) French cohort (GR2 study-NCT02450396) included consecutive women with a diagnosis of SpA (according to their rheumatologist) who wanted to become pregnant between 2015 and 2021. TTP (in months) was the main outcome criterion, prospectively calculated from the date of study inclusion to the date of conception. Data on demographics, disease characteristics, disease activity, severity and treatment were prospectively collected at inclusion and each year thereafter until pregnancy occurred. TTP and its associated factors were estimated by survival analysis (Shared Frailty Cox models), with a random centre effect and multiple imputation to address missing data.

RESULTS

We analysed 88 women included before conception. Among them, 56 (63.6%) became pregnant during follow-up. Median TTP was 16.1 (95% CI (12.2 to 25.3)) months. Mean preconceptional Bath Ankylosing Spondylitis Disease Activity Index at inclusion was 2.9 (±SD 2.1). Patients were treated with TNF inhibitors, non-steroidal anti-inflammatory drugs (NSAIDs), conventional synthetic disease-modifying antirheumatic drugs and glucocorticoids in 61 (69.3%), 23 (26.1%), 12 (13.6%) and 8 (9.1%) cases, respectively. The multivariate model found a significant association between TTP and age (HR) (per year) 1.22 95% CI (1.08 to 1.40); p<0.001) and the use of NSAIDs during preconception (HR 3.01 95% CI (2.15 to 3.85); p=0.01).

CONCLUSION

Age and NSAID use during preconception were significantly associated with a longer TTP, after adjustment for other confounding factors. These findings warrant caution in the use of NSAIDs in SpA patients trying to conceive.

Impact of menopause on women with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by chronic and systemic inflammation affecting multiple organ systems, including an increased risk of cardiovascular disease due to the SLE-associated hyperinflammatory state. SLE shows a strong female predominance, suggesting a potential role of sex hormones in the pathogenesis of the disease. Evidence suggests an earlier age of menopause among women with SLE, despite mixed findings regarding other markers of ovarian aging. In healthy populations, the menopausal transition is associated with important physiologic changes resulting in increased cardiometabolic risk and risk of osteoporosis. Thus, women with SLE who experience the inflammatory effects of the autoimmune condition combined with the (potentially earlier) menopausal transition may represent a particularly vulnerable group of individuals during a particular window of time. Little is known, however, about strategies for cardiovascular risk or bone loss mitigation in women with SLE during the menopausal transition. Further, despite lack of knowledge regarding the burden of menopausal symptoms in women with SLE, existing recommendations provide only cautionary guidance for the use of hormone replacement therapy to address menopausal symptoms in this population. Importantly, the data regarding both SLE and menopause-associated cardiovascular and osteoporotic risk demonstrate the critical need for additional research to identify the type and timing of treatments or interventions needed to best mitigate this increased risk.

Systemic lupus erythematosus and menopause

Estrogen has been known for a long time to be a trigger on auto-immunity and may influence the course of lupus. Women experiencing systemic lupus are at high risk for premature ovarian insufficiency if using cyclophosphamide, of osteoporosis, arterial ischemic diseases and venous thrombosis at young age. In about 30% of them, an antiphospholipid/anticoagulant antibody can occur which is associated with very high risk of thrombosis. However, the severity of the disease may vary and some women with lupus could benefit from a menopausal hormone therapy (MHT). As a consequence, management of menopause symptoms needs to evaluate carefully the condition of the patient, her lupus history and cardiovascular risk. We will describe the effect of lupus on menopause, of menopause on lupus and report in detail the literature available on MHT and the risk of lupus or the risk of flares in women with lupus. Some other options than MHT for the management of climacteric symptoms will be discussed.

Preliminary study on the changes of ovarian reserve, menstruation, and lymphocyte subpopulation in systemic lupus erythematosus (SLE) patients of childbearing age

Objective

The main aim of this study was to investigate the ovarian reserve, menstruation, and lymphocyte subpopulation in systemic lupus erythematosus (SLE) patients of childbearing age.

Methods

We enrolled 40 SLE patients of childbearing age and 40 age-matched healthy controls. Anti-Müllerian hormone (AMH) was tested by electrochemiluminescence, and lymphocyte subsets were tested by flow cytometry. Menstruation situation was obtained by interview.

Results

The AMH level of the SLE group was significantly lower than that of the control group ( p < 0.001), which was negatively correlated with erythrocyte sedimentation rate (ESR ( r = −0.316, p = 0.047)) and disease activity (SLEDAI ( r = −0.338, p = 0.033)). The AMH concentration of SLE patients with normal menstruation was higher than those with abnormal menstruation ( p < 0.001). The percentages of CD4+ T lymphocytes and NK (natural killer) cells in the SLE group were significantly lower than those in the control group ( p < 0.001). However, the percentages of B cells and CD8+ T lymphocytes in the SLE group were higher than those in the control group ( p < 0.05).

Conclusion

Decreased AMH and high incidence of abnormal menstruation indicated that autoimmunity activities of SLE can impair the ovarian reserve of female patients. Lymphocytes in SLE patients were in a state of disorder.

EULAR recommendations for women's health and the management of family planning, assisted reproduction, pregnancy and menopause in patients with systemic lupus erythematosus and/or antiphospholipid syndrome

OBJECTIVES

Develop recommendations for women's health issues and family planning in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS).

METHODS

Systematic review of evidence followed by modified Delphi method to compile questions, elicit expert opinions and reach consensus.

RESULTS

Family planning should be discussed as early as possible after diagnosis. Most women can have successful pregnancies and measures can be taken to reduce the risks of adverse maternal or fetal outcomes. Risk stratification includes disease activity, autoantibody profile, previous vascular and pregnancy morbidity, hypertension and the use of drugs (emphasis on benefits from hydroxychloroquine and antiplatelets/anticoagulants). Hormonal contraception and menopause replacement therapy can be used in patients with stable/inactive disease and low risk of thrombosis. Fertility preservation with gonadotropin-releasing hormone analogues should be considered prior to the use of alkylating agents. Assisted reproduction techniques can be safely used in patients with stable/inactive disease; patients with positive antiphospholipid antibodies/APS should receive anticoagulation and/or low-dose aspirin. Assessment of disease activity, renal function and serological markers is important for diagnosing disease flares and monitoring for obstetrical adverse outcomes. Fetal monitoring includes Doppler ultrasonography and fetal biometry, particularly in the third trimester, to screen for placental insufficiency and small for gestational age fetuses. Screening for gynaecological malignancies is similar to the general population, with increased vigilance for cervical premalignant lesions if exposed to immunosuppressive drugs. Human papillomavirus immunisation can be used in women with stable/inactive disease.

CONCLUSIONS

Recommendations for women's health issues in SLE and/or APS were developed using an evidence-based approach followed by expert consensus.

Evaluation of ovarian reserve using anti-müllerian hormone and antral follicle count in Sjögren's syndrome: Preliminary study

AIM

The aim of this study was to determine ovarian reserve status using anti-müllerian hormone (AMH) level and antral follicle count (AFC) in patients with Sjögren's syndrome (SS).

METHODS

Twenty-four women with SS diagnosed according to the classification criteria proposed by the American-European Consensus Group and 25 healthy women as controls were enrolled in this study. Ovarian reserve was assessed on clinical findings, AFC, and serum AMH and reproductive hormone levels.

RESULTS

Compared with the healthy controls, in the SS patients, the duration of menstrual cycle was significantly shorter (P = 0.043); serum AMH (P = 0.001) and AFC (P = 0.001) were significantly lower, and serum luteinizing hormone (LH) was significantly higher (P = 0.019). The right (P = 0.555) and left ovarian (P = 0.386) volumes were also lower but this did not reach statistical significance. Serum follicle-stimulating hormone (P = 0.327), estradiol (P = 0.241), and prolactin (P = 0.55) were similar between the two groups.

CONCLUSIONS

Ovarian reserve may be reduced in SS patients. For the assessment of ovarian reserve, serum AMH and ovarian AFC with serum LH may be useful. Further studies with long-term follow-up are required to determine the course of ovarian reserve abnormalities and best possible biomarkers of reduced ovarian reserve in SS patients.

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.

Assessment of anti-Müllerian hormone levels in premenopausal patients with systemic lupus erythematosus

OBJECTIVE

The ovarian reserve of patients with systemic lupus erythematosus (SLE) may be affected by disease activity and medication use. Studies have found that patients with SLE have similar fertility rates as healthy women of the same age. The goal of the present study was to investigate the ovarian reserve of patients with SLE by measuring anti-Müllerian hormone (AMH) levels, and compare it to that of healthy controls.

METHOD

This was a case-control study performed on 80 premenopausal women, of whom 40 fulfilled the 1997 American College of Rheumatology (ACR) criteria for SLE and 40 healthy controls paired by oral contraceptive use. Serum concentrations of AMH in peripheral venous blood were measured using a human AMH ELISA kit (CUSABIO, Wuhan, China).

RESULTS

AMH serum levels did not differ between patients with SLE and controls (22.79 ± 17.32 ng/ml versus 21.41 ± 16.22 ng/ml, respectively, p = 0.7), even after adjusting for age (21.03 ± 2.074 ng/ml versus 23.97 ± 2.71 ng/ml; p = 0.5). AHM levels were not significantly correlated with disease duration (r = 0.2; p = 0.3), body mass index (r = 0.2; p = 0.2) and disease activity (SLEDAI (r = 0.1; p = 0.7)) and damage indices (SLICC (r = 0.1; p = 0.7)). No associations were found between AMH and ethnicity, current smoking, as well as current or prior use of cyclophosphamide and other immunosuppressants.

CONCLUSION

In this cross-sectional study, women with SLE demonstrated similar AMH levels as healthy controls, suggesting preserved ovarian reserve in this population.
