Reproductive health in women with systemic lupus erythematosus compared to population controls

Sex hormones affect the pathogenesis and clinical characteristics of systemic lupus erythematosus

Systemic lupus erythematosus (SLE) affects women more frequently than men, similar to the female predilection for other autoimmune diseases. Moreover, male patients with SLE exhibit different clinical features than female patients. Sex-associated differences in SLE required special considerations for disease management such as during pregnancy or hormone replacement therapy (HRT). Sex hormones, namely, estrogen and testosterone, are known to affect immune responses and autoimmunity. While estrogen and progesterone promote type I immune response, and testosterone enhances T-helper 1 response. Sex hormones also influence Toll-like receptor pathways, and estrogen receptor signaling is involved in the activation and tolerance of immune cells. Further, the clinical features of SLE vary according to hormonal changes in female patients. Alterations in sex hormones during pregnancy can alter the disease activity of SLE, which is associated with pregnancy outcomes. Additionally, HRT may change SLE status. Sex hormones affect the pathogenesis, clinical features, and management of SLE; thus, understanding the occurrence and exacerbation of disease caused by sex hormones is necessary to improve its management.

Improved pregnancy outcomes in systemic lupus erythematosus: A retrospective study of pregnancies from a single centre in Denmark from 2010-2020 compared with the period 1990-2010

OBJECTIVES

Over the past decades new international guidelines recommend that pregnant Systemic lupus erythematosus (SLE) patients are monitored closely in a multi-professional team throughout pregnancy. The importance of low disease activity before pregnancy and continued treatment during pregnancy has been established. However, there is still a high risk of adverse pregnancy outcome (APO).The APO in a Danish SLE cohort was evaluated and compared with the results in a previous study cohort from the same centre and referral area.

METHODS

This retrospective cohort study used the local patient registry to identify pregnancies in SLE patients followed at the Department of Rheumatology, Aarhus University Hospital, Denmark, from January 2010 to October 2020. In total, 66 pregnancies were registered in 41 women. Data were compared with a previous retrospective study (1990-2010) from the same hospital.

RESULTS

Adverse pregnancy outcome occurred in 65% of pregnancies. Forty-seven pregnancies resulted in a live birth, while 15 ended in miscarriages. Compared to the 1990-2010 cohort, a numerical reduction in preterm deliveries (7.58% vs. 17.9%) and emergent caesarean (6.1% vs. 15.5%) was observed, although not reaching statistical significance (p = .07 in both cases). Further, a higher average birth weight (3045 g vs. 2870 g) as well as a higher number of pregnancies and live births per year were observed. Gestational hypertension was significantly reduced from 23.8% to 13.6% (p = .05). Significantly more patients were treated with prednisolone (66.7% vs 35.7%, p = .0002), hydroxychloroquine (6% vs. 73.4%, p < .0001) and acetylsalicylic acid (39.3% vs. 73.1%, p = .0001) in 2010-2020 compared to the 1990-2010.

CONCLUSION

We observed significant improvements in the frequency of some APOs in the recent 2010-2020 cohort compared with the previous cohort followed from 1990 to 2010. However, even though a specialized multi-professional team closely follows SLE patients through their pregnancies, pregnancy in SLE still carries a high risk of APO.

Pregnancy and Management in Women with Rheumatoid Arthritis, Systemic Lupus Erythematosus, and Obstetric Antiphospholipid Syndrome

Management of women with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and obstetric antiphospholipid syndrome (APS) during pregnancy presents unique clinical challenges. Women with both RA and SLE can have disease flares during pregnancy, leading to pregnancy complications, such as preeclampsia, small-for-gestational-age infants, and preterm delivery. Disease should be under control prior to conception. Women with obstetric APS need to be anticoagulated during pregnancy. Many but not all antirheumatic medications can be used during pregnancy and lactation.

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.

Racial Differences in Contraception Encounters and Dispensing Among Female Medicaid Beneficiaries With Systemic Lupus Erythematosus

OBJECTIVE

African American and Hispanic women with systemic lupus erythematosus (SLE) have the highest rates of potentially avoidable pregnancy complications, yet racial disparities in family planning among reproductive-age women with SLE have not been well-studied. Our objective was to examine whether there are racial differences in contraception encounters and dispensing among US Medicaid-insured women with SLE.

METHODS

Using Medicaid claims data from 2000-2010, we identified women ages 18-50 years with SLE. We examined contraception encounters and uptake over 24 months. We used multivariable logistic regression to estimate the odds ratio and 95% confidence interval by race/ethnicity of contraception encounters, any contraception dispensing, and highly effective contraception (HEC) use, adjusted for age, region, year, SLE severity, and contraindication to estrogen. We also compared contraception encounters and dispensing among women with SLE to the general population and women with diabetes mellitus.

RESULTS

We identified 24,693 reproductive-age women with SLE; 43% were African American, 35% White, 15% Hispanic, 4% Asian, 2% other race, and 1% American Indian/Alaska Native. Nine percent had a contraceptive visit, 10% received any contraception, and 2% received HEC. Compared to White women, African American and Asian women had lower odds of contraception dispensing, and African American women had lower odds of HEC use. Women with SLE were more likely to receive HEC than the general population and women with diabetes mellitus.

CONCLUSION

In this study of reproductive-age women with SLE, African American and Asian women had lower odds of contraception dispensing and African American women had lower odds of HEC use. Further study is needed to understand the factors driving these racial disparities among this population.

Evaluation of the Ovarian Reserve in Women With Systemic Lupus Erythematosus

Objective: Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disorder where the disease activity itself and the medications used for its treatment, may have adverse effects on ovarian function. This study aimed to assess the ovarian reserve (OR) in SLE patients.

Materials and methods: The anti-müllerian hormone (AMH) and the antral follicle count (AFC), two markers to evaluate the OR was assessed in 64 SLE patients and compared to normal individuals. Additionally, we assessed whether the disease per se or the pharmacological treatments affect the OR.

Results: Patients with SLE displayed alterations in the OR regardless of the presence of alterations of the menstrual cycle. The AFC and AMH were significantly lower in SLE patients with and without menstrual alterations when compared to control individuals (p<0.0001). However, the AFC and AMH levels were significantly correlated (p=0.006) in the SLE patients with menstrual alterations. Except for hydroxychloroquine that was statistically higher in SLE patients with menstrual alterations (p=0.04), the cumulative dose for cyclophosphamide, corticosteroid, and methotrexate was similar in SLE patients regardless of the occurrence of menstrual alterations.

Conclusion: The monitoring of AMH and AFC in SLE patients should be used to detect the rapid and irreversible decline of the OR to provide a possibility of pregnancy to the SLE patients.

Desire to have children and preferences regarding to pre-pregnancy counselling in women with SLE

OBJECTIVES

Pre-pregnancy counselling in women with systemic lupus erythematosus (SLE) is important in order to improve knowledge on the risks of pregnancy and to optimize pregnancy outcomes. Knowledge on the preferences of women with SLE regarding pre-pregnancy counselling have not yet been studied. In a closely monitored cohort of women with SLE we enquired about the present status of their wish to have children, and wish for and experiences with pre-pregnancy counselling.

METHODS

A questionnaire developed by physicians in collaboration with two women with SLE was sent to all (n = 177) women participating in the Amsterdam SLE cohort. The questionnaire comprised 32 items, of which 15 focused on the above-mentioned three themes.

RESULTS

A total of 124 women (70%) returned the questionnaire. The median disease duration was 13 years (interquartile range 9-19). Childlessness occurred in 51 women and 31% declared this was due to SLE [conscious decision (21%), stringent medical advice (6%), infertility due to medication (4%)]. Half of the women preferred the first pre-pregnancy counselling immediately after the SLE diagnosis (53%), together with their partner (69%). Information given by healthcare providers (81%) was preferred over information provided via brochures (35%) or the internet (26%). Pre-pregnancy face-to-face counselling from a rheumatologist and/or gynaecologist separately was preferred in 54%.

CONCLUSION

One-third of women attributed their childlessness to SLE-related reasons. Pre-pregnancy counselling was preferred shortly after the onset of the disease in a non-multidisciplinary setting. The results of this study underline the importance of timely pre-conceptional counselling by healthcare providers on fertility, risks and pregnancy outcomes in women with SLE.

Pregnancy and Management in Women with Rheumatoid Arthritis, Systemic Lupus Erythematosus, and Obstetric Antiphospholipid Syndrome

Management of women with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and obstetric antiphospholipid syndrome (APS) during pregnancy presents unique clinical challenges. Women with both RA and SLE can have disease flares during pregnancy, leading to pregnancy complications, such as preeclampsia, small-for-gestational-age infants, and preterm delivery. Disease should be under control prior to conception. Women with obstetric APS need to be anticoagulated during pregnancy. Many but not all antirheumatic medications can be used during pregnancy and lactation.

Breastfeeding in women affected by systemic lupus erythematosus: Rate, duration and associated factors

OBJECTIVE

Breastfeeding is a crucial moment for both mothers and child, providing a beneficial effect on child survival, nutrition, development and on maternal health. Despite the prevalent involvement of childbearing women in systemic lupus erythematosus (SLE), breastfeeding is still a neglected topic. The objective of this study was to evaluate breastfeeding frequency, duration and associated factors in SLE women.

METHODS

We consecutively enrolled SLE pregnant women reporting demographic, clinical, serological, gynaecological and obstetric data. Breastfeeding experience was evaluated by using a specific questionnaire. Disease activity was assessed before and during pregnancy as well as during postpartum.

RESULTS

A total of 57 pregnancies in 43 SLE women were included in the present study. In almost all the pregnancies, mothers planned to breastfeed their child (96.5%) and forty-one (71.9%) actually did breastfeed. The median time of breastfeeding was 3 months (IQR 7). Non-breastfeeding women showed a more frequent caesarean section (p = 0.0001), IUGR occurrence (p = 0.004) and disease relapse (p = 0.0001) after pregnancy. When comparing patients according with breastfeeding duration (cut-off 6 months), we found a significant more frequent smoking habitus (p = 0.02), caesarean section (p = 0.009), and joint involvement during postpartum (p = 0.0001) in women breastfeeding for less than or equal to 6 months, together with higher median BMI (p = 0.0001). Moreover, breastfeeding duration was positively associated with disease duration and hydroxychloroquine (HCQ) treatment during disease history, pregnancy and postpartum.

CONCLUSIONS

SLE women didn't show lower breastfeeding rate in comparison with general population but they presented higher prevalence of early discontinuation within three months. Early interruption was positively associated with smoking, BMI, joint involvement; meanwhile disease duration and HCQ treatment during postpartum were positively associated with a longer breastfeeding duration.

Maternal and Fetal Outcomes in Systemic Lupus Erythematosus Pregnancies

Abstract Introduction: To describe the maternal and fetal outcomes in systemic lupus erythematosus (SLE) pregnancies followed-up in a single tertiary referral centre. Methods: We performed a retrospective cohort study of 75 SLE pregnancies who were followed up in Singapore General Hospital over a 16-year period from 2000 to 2016. Adverse fetal and maternal outcomes including preterm delivery, miscarriages, fetal growth restriction, congenital heart block, neonatal lupus, pre-eclampsia and SLE flares were obtained from the medical records. Results: The mean age at conception was 32 years old (SD 3.8). The mean SLE disease duration was 5.9 years (SD 5.2). The majority (88%) had quiescent SLE disease activity at baseline. Most pregnancies resulted in a live birth (74.7%). The mean gestational age at birth was 37.4 weeks (SD 3.4). Adverse fetal outcomes occurred in 53.3%. Preterm delivery (33.9%), miscarriages (20%) and fetal growth restriction (17.3%) were the most frequent adverse fetal outcomes. There was 1 neonatal death and SLE flares occurred in a third (33%). In the subgroup of SLE pregnancies with antiphospholipid syndrome, there were higher SLE flare rates (40%) and adverse fetal outcomes occurred in 8 pregnancies (80%). There were no predictive factors identified for all adverse fetal and maternal outcomes. In the subgroup analysis of preterm delivery, anti-Ro (SS-A) antibody positivity and hydroxychloroquine treatment were associated with a lower risk of preterm delivery. Conclusion: Although the majority had quiescent SLE disease activity at baseline, SLE pregnancies were associated with high rates of adverse fetal and maternal outcomes. Keywords: Antiphospholipid syndrome, anti-La (SS-B) antibody, anti-Ro (SS-A) antibody, lupus nephritis

Pregnancy in systemic lupus erythematosus

OBJECTIVES

Systemic lupus erythematosus (SLE) is a chronic illness that often affects women of reproductive age. The objectives of this article are to review the impact of SLE on pregnancy and current management strategies, including commonly used therapies.

METHODS

We conducted a review of available literature on the clinical course of SLE, diagnosis, management and pregnancy complications.

RESULTS

SLE has a variable clinical course characterized by flares and periods of remission and can present unique challenges in the management of obstetric patients. Pregnancy in patients with SLE is associated with multiple risks, including fetal loss, preterm birth, fetal growth restriction, and hypertensive disease. With advancements in disease treatment, many women have favorable pregnancy outcomes, but appropriate preconception counseling and disease management remain important tools in reducing complications.

CONCLUSION

Given the implications SLE can have on women of reproductive age and in pregnancy, understanding the disease course and management is important in order to optimize pregnancy outcomes.

Sex Differences in Systemic Lupus Erythematosus: Epidemiology, Clinical Considerations, and Disease Pathogenesis

Systemic lupus erythematosus (SLE) is a chronic, multiorgan, systemic autoimmune disease that is more common in women than men and is typically diagnosed during reproductive age, necessitating sex-specific considerations in care. In women there is no substantive evidence to suggest that SLE reduces fertility, but subfertility may occur as a result of active disease, immunosuppressive drugs, and age-related declines in fertility related to delays in childbearing. Although pregnancy outcomes have improved, SLE still poses risks in pregnancy that contribute to poorer maternal and fetal outcomes. Cyclophosphamide, an important agent for the treatment of severe or life-threatening lupus, may adversely affect fertility, particularly with increases in dose and patient age. Fertility preservation techniques are therefore an important consideration for women and men before cytotoxic treatment. There is mixed evidence as to whether exogenous estrogen in the form of oral contraceptive pills or hormone replacement therapy may increase the risk for the development of SLE, but among women with SLE already diagnosed, combined oral contraceptive pills and hormone replacement therapy do not confer risk for severe flare and remain important in reproductive care. The higher incidence of SLE in women may nonetheless be attributable to effects of endogenous estrogen, as well as failures in X chromosome inactivation, increased Toll-like receptor gene products, and changes in microRNA function. A greater appreciation of the biological underpinnings and consequences of sex differences in SLE may lead to more targeted treatments and improved outcomes for patients with SLE.

Use of combined hormonal contraceptives among women with systemic lupus erythematosus with and without medical contraindications to oestrogen

OBJECTIVES

To assess the prevalence of combined hormonal contraceptives (CHCs) in reproductive-age women with SLE with and without possible contraindications and to determine factors associated with their use in the presence of possible contraindications.

METHODS

This observational cohort study included premenopausal women ages 18-45 years enrolled in the SLICC Registry ⩽15 months after SLE onset, with annual assessments spanning 2000-2017. World Health Organization Category 3 or 4 contraindications to CHCs (e.g. hypertension, aPL) were assessed at each study visit. High disease activity (SLEDAI score >12 or use of >0.5 mg/kg/day of prednisone) was considered a relative contraindication.

RESULTS

A total of 927 SLE women contributed 6315 visits, of which 3811 (60%) occurred in the presence of one or more possible contraindication to CHCs. Women used CHCs during 512 (8%) visits, of which 281 (55%) took place in the setting of one or more possible contraindication. The most frequently observed contraindications were aPL (52%), hypertension (34%) and migraine with aura (22%). Women with one or more contraindication were slightly less likely to be taking CHCs [7% of visits (95% CI 7, 8)] than women with no contraindications [9% (95% CI 8, 10)].

CONCLUSION

CHC use was low compared with general population estimates (>35%) and more than half of CHC users had at least one possible contraindication. Many yet unmeasured factors, including patient preferences, may have contributed to these observations. Further work should also aim to clarify outcomes associated with this exposure.

Mechanisms of Sex Disparities in Cardiovascular Function and Remodeling

Epidemiological studies demonstrate disparities between men and women in cardiovascular disease prevalence, clinical symptoms, treatments, and outcomes. Enrollment of women in clinical trials is lower than men, and experimental studies investigating molecular mechanisms and efficacy of certain therapeutics in cardiovascular disease have been primarily conducted in male animals. These practices bias data interpretation and limit the implication of research findings in female clinical populations. This review will focus on the biological origins of sex differences in cardiovascular physiology, health, and disease, with an emphasis on the sex hormones, estrogen and testosterone. First, we will briefly discuss epidemiological evidence of sex disparities in cardiovascular disease prevalence and clinical manifestation. Second, we will describe studies suggesting sexual dimorphism in normal cardiovascular function from fetal life to older age. Third, we will summarize and critically discuss the current literature regarding the molecular mechanisms underlying the effects of estrogens and androgens on cardiac and vascular physiology and the contribution of these hormones to sex differences in cardiovascular disease. Fourth, we will present cardiovascular disease risk factors that are positively associated with the female sex, and thus, contributing to increased cardiovascular risk in women. We conclude that inclusion of both men and women in the investigation of the role of estrogens and androgens in cardiovascular physiology will advance our understanding of the mechanisms underlying sex differences in cardiovascular disease. In addition, investigating the role of sex-specific factors in the development of cardiovascular disease will reduce sex and gender disparities in the treatment and diagnosis of cardiovascular disease. © 2019 American Physiological Society.

Anti-müllerian hormone and ovarian reserve in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic immune-mediated inflammatory disease that affects predominantly females during childbearing age (Lateef and Petri Best Pract Res Clin Rheumatol 27(3):435-447, 2013). Fertility in SLE patients is considered to be normal (Clowse et al. Arthritis Care Res (Hoboken) 64(5):668-674, 2012; Ekblom-Kullberg et al. Scand J Rheumatol 38:375-380, 2009) but several known factors may negatively influence fertility. Immune mechanisms are also thought to be an important cause of premature ovarian senescence, characterized by reduced ovarian reserve markers such as anti-Müllerian hormone (AMH) (Oktem et al. Obstet Gynecol Surv 70(3):196-210, 2015; Bermas and Sammaritano Fertil Res Pract 1:13, 2015; Østensen Int J Clin Rheumtol 8(1):27-37, 2013; Ulug et al. Am J Reprod Immunol 72(1):85-88, 2014; Lawrenz et al. Lupus 20(11):1193-1197, 2011). We evaluated the ovarian reserve of women in reproductive age with SLE, by measuring AMH levels and we compared it to that of non-SLE women. We also analyzed the association of SLE disease characteristics with AMH levels. AMH levels were decreased in this population of SLE women, accounting for a high proportion of women with criteria for low ovarian reserve. Age and SLE damage were associated with abnormally lower AMH levels in our SLE patients. In this way, SLE may have a negative influence on the ovarian reserve.

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.

Systemic lupus erythematosus and malignancies risk

OBJECTIVE

To evaluate the risk of site-specific and overall malignancies after SLE and explore the potential influencing factors.

METHODS

We searched electronic databases for articles that assessed the risk of malignancies after SLE through February 2015. We extracted the incidence rates (IRs) and corresponding 95 % confidence intervals (CIs). We used random effects models to calculate the pooled IRs and assessed the impact of study designs, region, gender, age and duration of follow-up.

RESULTS

Eighteen studies were included, giving a pooled IR of 1.44 (95 % CI 1.23-1.69). Europeans, Americans and Asians showed a IR of 1.56 (95 % CI 1.07-2.28), 1.18 (95 % CI 1.01-1.39) and 1.62 (95 % CI 1.38-1.89), respectively. Males and females (eight studies) demonstrated a IR of 1.34 (95 % CI 1.07-1.67) and 1.51 (95 % CI 1.20-1.90), respectively. Prospective and retrospective studies showed a IR of 1.55 (95 % CI 0.97-2.47) and 1.44 (95 % CI 1.21-1.73), respectively. An increment of 10 years of age conferred a decrease in IR of 0.6. An increment of 5 years of SLE duration conferred a decrease in IR of 2.5. An increased IR of malignancies was observed in NHL, vagina/vulva, hematology, head/neck, leukemia, thyroid, liver/gallbladder, kidney, anal, cervix, esophagus, lung and pancreas. A decreased IR of malignancies was observed in ovary and colon/rectum.

CONCLUSIONS

SLE patients had an increased risk of developing overall malignancies, particularly among Asians and females. Age and SLE duration are inversely associated with the risk of overall malignancies. SLE patients showed a different role in the onset of various site-specific malignancies.

Regular menstrual cycles do not rule out ovarian damage in adult women with systemic lupus erythematosus

The aim of this study was to evaluate ovarian reserve markers in women with systemic lupus erythematosus (SLE) and regular menstrual cycles, and explore the relationship of such markers with clinical and treatment features. This was a case-control study including 27 women with SLE and 27 controls. All participants were aged 18-40 years, were eumenorrheic and had not used hormone therapy or hormone contraceptives in the past six months. Clinical manifestations of SLE, past and current use of immunosuppressive therapy and organ damage index were assessed at a regular follow-up visit, while antral follicle count (AFC), serum anti-Mullerian hormone (AMH) and follicle-stimulating hormone (FSH) were assessed at early follicular phase of menstrual cycle. AFC was significantly reduced in SLE women [median (interquartile interval) 7 (5-11) versus 11 (7-12), p = 0.029]. AMH levels were more heterogeneous in SLE patients compared to the control group [1.23 (0.24-4.63) ng/ml versus 1.52 (1.33-1.88) ng/ml]. The SLE and control groups had similar serum FSH levels [6.44 (4.19-7.69) versus 7.5 (6.03-8.09) IU/L, p = 0.135]. AFC was inversely correlated with organ damage index (p = 0.046) and cumulative dose of cyclophosphamide (p = 0.028), while AMH levels were negatively correlated with the maximal dose of corticosteroid ever used (p = 0.003). These findings suggest that ovarian reserve may be decreased in women with SLE despite regular menstrual cycles.

Estrogen in cardiovascular disease during systemic lupus erythematosus

PURPOSE

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that disproportionately affects women during their childbearing years. Cardiovascular disease is the leading cause of mortality in this patient population at an age when women often have low cardiovascular risk. Hypertension is a major cardiovascular disease risk factor, and its prevalence is markedly increased in women with SLE. Estrogen has traditionally been implicated in SLE disease progression because of the prevalence of the disease in women; however, its role in cardiovascular risk factors such as hypertension is unclear. The objective of this review is to discuss evidence for the role of estrogen in both human and murine SLE with emphasis on the effect of estrogen on cardiovascular risk factors, including hypertension.

METHODS

PubMed was used to search for articles with terms related to estradiol and SLE. The references of retrieved publications were also reviewed.

FINDINGS

The potential permissive role of estrogen in SLE development is supported by studies from experimental animal models of lupus in which early removal of estrogen or its effects leads to attenuation of SLE disease parameters, including autoantibody production and renal injury. However, data about the role of estrogens in human SLE are much less clear, with most studies not reaching firm conclusions about positive or negative outcomes after hormonal manipulations involving estrogen during SLE (ie, oral contraceptives, hormone therapy). Significant gaps in knowledge remain about the effect of estrogen on cardiovascular risk factors during SLE. Studies in women with SLE were not designed to determine the effect of estrogen or hormone therapy on blood pressure even though hypertension is highly prevalent, and risk of premature ovarian failure could necessitate use of hormone therapy in women with SLE. Recent evidence from an experimental animal model of lupus found that estrogen may protect against cardiovascular risk factors in adulthood. In addition, increasing evidence suggests that estrogen may have distinct temporal effects on cardiovascular risk factors during SLE.

IMPLICATIONS

Data from experimental models of lupus suggest that estrogens may have an important permissive role for developing SLE early in life. However, their role in adulthood remains unclear, particularly for the effect on cardiovascular disease and its risk factors. Additional work is needed to understand the effect of estrogens in human SLE, and preclinical studies in experimental models of SLE may contribute important mechanistic insight to further advance the field.

Side effects unrelated to disease activity and acceptability of highly effective contraceptive methods in women with systemic lupus erythematosus: a randomized, clinical trial

OBJECTIVES

To assess the side effects unrelated to disease activity and the acceptability of combined oral contraceptives (COCs), progestin-only pills (POPs) and copper-releasing intrauterine devices (IUDs) in women with systemic lupus erythematosus (SLE).

STUDY DESIGN

A randomized clinical trial including 162 women with SLE, assigned to COC (n=54), POP (n=54) or IUD (n=54). Follow-up visits were conducted after 1, 2, 3, 6, 9 and 12 months of treatment to monitor the presence of symptoms, changes in body weight and blood pressure as well as the development of health problems other than those relating to lupus. Reasons for discontinuation and satisfaction with the use of the assigned method were recorded at the end of treatment. Statistical analysis included descriptive statistics, repeated measure analyses and Kaplan-Meier curves.

RESULTS

Significantly different discontinuation rates due to any reason [35%, 55%, 29% (p<0.01)] or nonmedical reasons [(11%, 31%, 4% (p<0.05)] were observed among the COC, POP and IUD groups. Nausea was most frequent among COC users, dysmenorrhea among IUD users and acne and hirsutism among POP users. Mean blood pressures remained unchanged. Mild increases in body weight were observed over time in all treatment groups. Most women were satisfied with the use of the assigned contraceptive method.

CONCLUSIONS

Oral contraceptives and IUD are acceptable birth control methods for patients with lupus, when counseling and specialized health attention are provided; however, the acceptability of POP appears to be inferior. Side effects unrelated to lupus disease activity are not frequent reasons to discontinue the contraceptive methods.

IMPLICATIONS

This study delves into an area that has not been explored among patients with lupus. Our findings on the associated side effects and reasons for discontinuing COCs, POPs or copper-bearing IUDs may be useful in improving contraceptive counseling for women with lupus. Furthermore, they also heighten our knowledge on the reasons that may preclude the widespread use of effective contraceptives among lupus patients.

Comparing female-based contraceptive methods in patients with systemic lupus erythematosus, rheumatoid arthritis and a healthy population

AIM

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that is 10 times more prevalent in women, particularly those of reproductive age. The varying effects of pregnancy on SLE and the differences between available SLE treatments make pregnancy timing and contraceptive methods significant. We aimed to determine the contraceptive methods used by SLE patients in the north-west part of Turkey, and compared them with those used by rheumatoid arthritis (RA) patients and healthy controls.

METHOD

The study was comprised of 113 SLE patients, and 84 RA patients at the Rheumatology Outpatient Clinic of Uludag University Medical Faculty.

RESULTS

Twenty-three (20.3%) out of 113 SLE patients, 18 (21.4%) out of 84 RA patients and 17 (18.6%) out of 92 healthy controls did not use any contraceptive methods. Use of the withdrawal and condom methods was more common among SLE patients, accounting for 61% (withdrawal 32.7%, condom 28.3%). Moreover, 52% of SLE and 50% of RA patients were neither given information about contraceptive methods nor offered a suggested method, compared to 34% in the health control group.

CONCLUSIONS

The prevalence of oral contraceptive use is low in Turkey; notwithstanding the withdrawal and condom methods, which are frequently used despite their high failure risk. Although pregnancy timing is of great importance for SLE patients, necessary information and recommendations concerning contraceptive methods have been ignored and the use of effective methods is not a priority.

17β-Estradiol protects against the progression of hypertension during adulthood in a mouse model of systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disorder with a high prevalence of hypertension and cardiovascular disease. Because SLE predominantly affects women, estrogen is commonly implicated as a contributor to SLE disease progression. Using an established mouse model of SLE (female NZBWF1), we tested whether estrogen has a causal role in the development of hypertension in adulthood. Thirty-week-old SLE and control mice (NZW/LacJ) underwent either a sham or ovariectomy (OVX) procedure. 17β-Estradiol (E2; 5 μg/mouse, twice/week, subcutaneously) was administered to a subset of OVX mice. Mean arterial pressure (in mm Hg) was increased in SLE mice (134±4 versus 119±3 in controls). Contrary to our hypothesis, OVX exacerbated the hypertension in female SLE mice (153±3; P<0.05 versus SLE sham), and repletion of E2 prevented the OVX-induced increase in blood pressure (132±2). The prevalence of albuminuria was increased in SLE mice compared with controls (37% versus 0%). OVX increased the prevalence in SLE mice (70% versus 37% in SLE shams). Repletion of E2 completely prevented albuminuria in OVX SLE mice. Renal cortical tumor necrosis factor α was increased in SLE mice compared with controls and was further increased in OVX SLE. The OVX-induced increase in renal tumor necrosis factor α expression was prevented by repletion of E2. Treatment of OVX SLE mice with the tumor necrosis factor α inhibitor, etanercept, blunted the OVX-induced increase in blood pressure (140±2) and prevalence of albuminuria (22%). These data suggest that 17β-estradiol protects against the progression of hypertension during adulthood in SLE, in part, by reducing tumor necrosis factor α.

Ethnic differences in the number of miscarriages, number of children, perceived family support and the impact of the disease on daily living in patients with systemic lupus erythematosus

Our aim was to test for ethnic differences in the number of children, number of miscarriages, family support and the impact of the disease on daily living among patients with systemic lupus erythematosus (SLE). Patients with SLE (n = 54) who attended two hospitals in Essex, UK, were asked to complete a semi-structured, validated questionnaire. The number of children and the number of miscarriages were reported numerically. The level of family support and the impact of the disease on daily living were reported using 10 cm visual analogue scales (VAS) in which 10 cm represented the maximum support and worst effect on daily living, respectively. There were 20 Caucasian, 22 Asian and 12 African/Afro-Caribbean patients. There were 50 females and four males. The mean ± standard deviation (SD) age was 45.9 ± 12.2 years, and the mean ± SD age at disease onset was 35.6 ± 11.1 years. Overall, 34/50 female patients (68 %) reported having children of their own, while 17/50 female patients (34 %) reported one or more miscarriages. The miscarriages were mostly reported by Caucasian patients (45 % versus 18.1 % for Asian and 33.3 % for African/Afro-Caribbean patients; P < 0.05). All of the groups received support from their families (90.7 % overall), but the level of support was greater for Caucasian (mean ± SD VAS, 6.6 ± 3.4 cm) than for Asian (5.4 ± 3.9 cm) and African/Afro-Caribbean (5.4 ± 4.9 cm) patients (P = 0.06). More than half of the patients (53.7 %) reported a severe impact of SLE on daily living, while 13 % reported a moderate impact, 22.2 % reported a mild impact and 11.1 % reported no impact. The impact of SLE on daily living was significantly worse for African/Afro-Caribbean patients compared with Asian patients (P < 0.05). Overall, one in two patients with SLE reported having children of their own, while one in three patients reported having at least one miscarriage. Ninety percent of the patients received family support for their disease. Miscarriages and family support were more frequently reported by Caucasian patients. Asian patients had more children and experienced fewer miscarriages, while African/Afro-Caribbean patients reported a worse impact of the disease on daily living compared with the other ethnic groups.

Excess female siblings and male fetal loss in families with systemic lupus erythematosus

OBJECTIVE

Systemic lupus erythematosus (SLE) occurs more frequently among women than men. We aimed to determine whether the male-female ratio in SLE families is different from what would be expected by chance, and whether excess male fetal loss is found.

METHODS

All patients with SLE met the revised American College of Rheumatology classification criteria, while unaffected subjects were shown not to satisfy these same criteria. Putative family relationships were confirmed by genetic testing. Pregnancy history was obtained from all subjects, including unrelated control women. Adjusted Wald binomial confidence intervals were calculated for ratio of boys to girls in families and compared to the expected ratio of 1.06.

RESULTS

There were 2579 subjects with SLE, with 6056 siblings. Considering all subjects, we found 3201 boys and 5434 girls (ratio 0.59, of 95% CI 0.576-0.602). Considering only the SLE-unaffected siblings, there were 2919 boys and 3137 girls (ratio 0.93, 95% CI 0.92-0.94). In both cases, the ratio of males to females was statistically different from the known birth rate. Among patients with SLE as well as among their sisters and mothers, there was an excess of male fetal loss compared to the controls.

CONCLUSION

Siblings of patients with SLE are more likely than expected to be girls. This finding may be in part explained by excess male fetal loss, which is found among patients with SLE and their first-degree relatives.

Managing pregnancy in inflammatory rheumatological diseases

Historically, pregnancy in women with many inflammatory rheumatic diseases was not considered safe and was discouraged. Combined care allows these pregnancies to be managed optimally, with the majority of outcomes being favorable. Disease activity at the time of conception and anti-phospholipid antibodies are responsible for most complications. Disease flares, pre-eclampsia, and thrombosis are the main maternal complications, whereas fetal loss and intrauterine growth restriction are the main fetal complications. Antirheumatic drugs used during pregnancy and lactation to control disease activity are corticosteroids, hydroxychloroquine, sulphasalzine, and azathioprine. Vaginal delivery is possible in most circumstances, with cesarean section being reserved for complications.

Rheumatic diseases and pregnancy

PURPOSE OF REVIEW

This review discusses how inflammatory rheumatic diseases [rheumatoid arthritis, ankylosing spondylitis, systemic lupus erythematosus (SLE)] of the mother can influence the course of pregnancy and the development of the fetus. Antirheumatic drug therapy of the mother and strategies to prevent fetal complications namely in SLE must be considered with care.

RECENT FINDINGS

The current literature is presented discussing hypotheses about the immunologic mechanisms leading to amelioration or exacerbation of the rheumatic symptoms in rheumatoid arthritis and ankylosing spondylitis during pregnancy. In SLE, several recent studies have been published concerning fetal complications in the antiphospholipid syndrome and in Ro/SSA-positive and La/SSB-positive mothers and how to diagnose, treat, or prevent these.

SUMMARY

Today, women with inflammatory rheumatic diseases are normally fertile and can be encouraged to become pregnant, when there is a stable and quiescent phase of the disease. This is in particular important for patients with SLE, although pregnancy outcome in SLE has improved over the last decades. Pregnancy in SLE is still a high-risk period during the disease course with the highest risk in women with active lupus nephritis. In contrast, women with rheumatoid arthritis develop amelioration of the rheumatic symptoms during the course of pregnancy in most cases; female ankylosing spondylitis patients are likely to show unaltered or aggravated symptoms of back pain and impaired function.

Contraceptive counseling and use among women with systemic lupus erythematosus: a gap in health care quality?

OBJECTIVE

Disease activity and medication use can complicate pregnancies in patients with systemic lupus erythematosus (SLE). We therefore examined contraceptive counseling and use among women in the University of California, San Francisco Lupus Outcomes Study.

METHODS

In 2008, we queried participants regarding their pregnancy intentions, contraceptive use, and receipt of contraceptive counseling. Premenopausal women age <45 years who were sexually active with men were considered at risk of pregnancy. We compared self-reported rates of contraceptive counseling and use stratified by treatment with teratogenic medications and by history of thrombosis or antiphospholipid antibodies (aPL), using chi-square tests. We used logistic regression models to examine predictors of contraceptive counseling and use.

RESULTS

Among 206 women, 86 were at risk for unplanned pregnancy. Most (59%) had not received contraceptive counseling in the last year, 22% reported inconsistent contraceptive use, and 53% depended solely on barrier methods. Intrauterine device contraceptives (IUDs) were used by 13%. Women using potentially teratogenic medications were no more likely to have received contraceptive counseling, to have used contraception consistently, or to have used more effective contraceptives. A history of thrombosis or aPL did not account for low rates of hormonal methods. Four women with a history of thrombosis or aPL were using estrogen-containing contraceptives.

CONCLUSION

Most women at risk for unplanned pregnancy reported no contraceptive counseling in the past year, despite common use of potentially teratogenic medications. Many relied upon contraceptive methods with high failure rates; few used IUDs. Some were inappropriately using estrogen-containing contraceptives. These findings suggest the need to improve the provision of contraceptive services to women with SLE.

Management of rheumatic diseases during pregnancy

Systemic rheumatic diseases commonly affect women during the childbearing years. Many women with these diseases may be contemplating pregnancy or discover an inadvertent pregnancy, leading to concerns regarding medication use, changes in disease activity during pregnancy, safety of lactation, and future ability to care for a child given the presence of chronic illnesses. There are outstanding reviews that summarize the safety and use of immunosuppressive medications during pregnancy. However, in addition to medication use, providers need to be aware of the available data regarding fertility, pregnancy outcomes, delivery, and lactation issues that may be specific to individual diseases. Optimally, women should plan pregnancies to occur around times of disease quiescence, several months after potentially teratogenic medications have been discontinued. The course of the underlying rheumatic disease during pregnancy is variable, and there are no specific clinical or laboratory variables that consistently predict disease improvement or worsening during pregnancy. Recent data suggest that increased disease activity in women with most autoimmune diseases during pregnancy may lead to increased risk of premature delivery, low-birth-weight infants, and other adverse pregnancy outcomes. Arthritis involving the cervical spine and hips may impact delivery and must be considered by both obstetricians and obstetric anesthesiologists. Data are mixed regarding the impact of breastfeeding on underlying autoimmune diseases; the choice to continue breastfeeding is a personal decision.
