Systemic Lupus Erythematosus: A Review.

Importance: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by inflammation and immune-mediated injury to multiple organ systems, including the mucocutaneous, musculoskeletal, hematologic, and kidney systems. Approximately 3.4 million people worldwide have received a diagnosis of SLE. Observations: Approximately 90% of people with SLE are female. Although there are no uniformly accepted diagnostic criteria for SLE, the 2019 European Alliance of Associations for Rheumatology (formerly the European League Against Rheumatism)/American College of Rheumatology classification criteria developed for scientific study are an estimated 96.1% sensitive and 93.4% specific for SLE. These classification criteria include both clinical factors, such as fever, cytopenia, rash, arthritis, and proteinuria, which may be indicative of lupus nephritis; and immunologic measures, such as SLE-specific autoantibodies and low complement levels. Approximately 40% of people with SLE develop lupus nephritis, and an estimated 10% of people with lupus nephritis develop end-stage kidney disease after 10 years. The primary goal of treatment is to achieve disease remission or quiescence, defined by minimal symptoms, low levels of autoimmune inflammatory markers, and minimal systemic glucocorticoid requirement while the patient is treated with maintenance doses of immunomodulatory or immunosuppressive medications. Treatment goals include reducing disease exacerbations, hospitalizations, and organ damage due to the disease or treatment toxicity. Hydroxychloroquine is standard of care for SLE and has been associated with a significant reduction in mortality. Treatments in addition to hydroxychloroquine are individualized, with immunosuppressive agents, such as azathioprine, mycophenolate mofetil, and cyclophosphamide, typically used for treating moderate to severe disease. Three SLE medications were recently approved by the Food and Drug Administration: belimumab (for active SLE in 2011 and for lupus nephritis in 2020), voclosporin (for lupus nephritis), and anifrolumab (for active SLE). Conclusions and Relevance: Systemic lupus erythematosus is associated with immune-mediated damage to multiple organs and increased mortality. Hydroxychloroquine is first-line therapy and reduces disease activity, morbidity, and mortality. When needed, additional immunosuppressive and biologic therapies include azathioprine, mycophenolate mofetil, cyclophosphamide, belimumab, voclosporin, and anifrolumab.

The Psychosocial Impact of Undifferentiated Connective Tissue Disease on Patient Health and Well-Being: A Qualitative Study.

METHODS: We identified 20 adult patients with UCTD enrolled in the UCTD and Overlap Registry at our tertiary care level hospital. A licensed clinical social worker administered a 30-minute semistructured interview by telephone. The standardized questionnaire consisted of 14 open-ended questions on UCTD. A team of physicians, research coordinators, and a social worker used grounded theory to analyze the qualitative data and identify themes. RESULTS: Among 14/20 study participants (100% female; mean age, 53.6 ± 13.2 years [range, 27-74 years]), all had at least an associate's/bachelor's degree; 9 (64%) were White. The mean disease duration was 14.5 ± 13.5 years (range, 0.5-44 years). Nine study participants (64%) were engaged in counseling or mindfulness training. Ten specific psychosocial themes and categories emerged, including the need for professional guidance and peer and family support to increase awareness, reduce isolation, and promote self-efficacy. CONCLUSIONS: Emerging themes from semistructured interviews of women with UCTD at a major academic center suggest the need for psychosocial interventions (e.g., patient support groups, educational materials, peer counselors) to help UCTD patients manage and cope with their illness. Future studies evaluating the psychosocial impact of UCTD diagnosis on diverse cohorts are needed.

Which Hormones and Contraception for Women with APS? Exogenous Hormone Use in Women with APS.

PURPOSE OF REVIEW: Use of exogenous estrogen carries significant risk for patients with prothrombotic disorders including those with antiphospholipid antibody (aPL) and antiphospholipid syndrome (APS). This review summarizes current knowledge of contraceptive and other hormone therapies for aPL-positive and APS women and highlights knowledge gaps to guide future research. RECENT FINDINGS: Studies support very low risk for most progestin-only contraceptives in patients with increased thrombotic risk, but suggest increased VTE risk with depot-medroxyprogesterone acetate. Highest efficacy contraceptives are intrauterine devices and subdermal implants, and these are recommended for women with aPL/APS. Progestin-only pills are effective and low risk. Perimenopausal symptoms may be treated with nonhormone therapies in aPL/APS patients: vasomotor symptoms can improve with nonhormonal medications and cognitive behavioral therapy, and genitourinary symptoms often improve with intravaginal estrogen that has limited systemic absorption.

Management of Systemic Lupus Erythematosus During Pregnancy.

Reproductive issues including contraception, fertility, and pregnancy are important components of the comprehensive care of women with systemic lupus erythematosus (SLE). SLE pregnancies are complicated due to risk for maternal disease exacerbation and potential for fetal and neonatal complications. Pre-pregnancy assessment is important to identify patients with severe disease-related damage who should avoid pregnancy, counsel patients to conceive when disease has been stable and inactive on appropriate medications, and assess relevant risk factors including renal disease, antiphospholipid antibody, and anti-Ro/SS-A and anti-La/SS-B antibodies. With careful planning, monitoring, and care, most women with SLE can anticipate a successful pregnancy.

Complement activation predicts adverse pregnancy outcome in patients with systemic lupus erythematosus and/or antiphospholipid antibodies.

OBJECTIVE: Studies in mouse models implicate complement activation as a causative factor in adverse pregnancy outcomes (APOs). We investigated whether activation of complement early in pregnancy predicts APOs in women with systemic lupus erythematosus (SLE) and/or antiphospholipid (aPL) antibodies. METHODS: The PROMISSE Study enrolled pregnant women with SLE and/or aPL antibodies (n=487) and pregnant healthy controls (n=204) at <12 weeks gestation and evaluated them monthly. APOs were: fetal/neonatal death, preterm delivery <36 weeks because of placental insufficiency or preeclampsia and/or growth restriction <5th percentile. Complement activation products were measured on serial blood samples obtained at each monthly visit. RESULTS: APO occurred in 20.5% of SLE and/or aPL pregnancies. As early as 12-15 weeks, levels of Bb and sC5b-9 were significantly higher in patients with APOs and remained elevated through 31 weeks compared with those with normal outcomes. Moreover, Bb and sC5b-9 were significantly higher in patients with SLE and/or aPL without APOs compared with healthy controls. In logistic regression analyses, Bb and sC5b-9 at 12-15 weeks remained significantly associated with APO (ORadj=1.41 per SD increase; 95% CI 1.06 to 1.89; P=0.019 and ORadj=1.37 per SD increase; 95% CI 1.05 to 1.80; P=0.022, respectively) after controlling for demographic and clinical risk factors for APOs in PROMISSE. When analyses were restricted to patients with aPL (n=161), associations between Bb at 12-15 weeks and APOs became stronger (ORadj=2.01 per SD increase; 95% CI 1.16 to 3.49; P=0.013). CONCLUSION: In pregnant patients with SLE and/or aPL, increased Bb and sC5b-9 detectable early in pregnancy are strongly predictive of APOs and support activation of complement, particularly the alternative pathway, as a contributor to APOs.

The prevention, screening and treatment of congenital heart block from neonatal lupus: a survey of provider practices.

Objective: To survey an international sample of providers to determine their current practices for the prevention, screening, and treatment of congenital heart block (CHB) due to maternal Ro/SSA antibodies. Methods: A survey was designed by the organizing committee of the 9th International Conference of Reproduction, Pregnancy and Rheumatic Diseases. It was sent to attendants of the conference and authors of recent publications or abstracts at ACR 2012, 2013 or 2014 on rheumatic diseases and pregnancy. Results: In anti-Ro/SSA positive women, 80% of 49 respondents recommended screening by serial fetal echocardiogram (ECHO), with most starting at week 16 (59%) and stopping at week 28 (25%), although the time to stop varied widely. For women without a prior infant with neonatal lupus, respondents recommend every other week (44%) or weekly (28%) fetal ECHOs. For women with a prior infant with neonatal lupus, 80% recommend weekly fetal ECHOs. To prevent CHB, HCQ was recommended by 67% of respondents and most would start pre-pregnancy (62%). Respondents were asked about medications to treat varying degrees of CHB in a 20-week pregnant, anti-Ro and La positive SLE patient. For first degree, respondents recommended starting dexamethasone (53%) or HCQ (43%). For second degree, respondents recommended starting dexamethasone (88%). For third degree, respondents recommended starting dexamethasone (55%) or IVIg (33%), although 27% would not start treatment. Conclusion: Despite the absence of official guidelines, many physicians with a focus on pregnancy and rheumatic disease have developed similar patterns in the screening, prevention and treatment of CHB.

Angiogenic factor imbalance early in pregnancy predicts adverse outcomes in patients with lupus and antiphospholipid antibodies: results of the PROMISSE study.

BACKGROUND: Over 20% of pregnancies in patients with systemic lupus erythematosus (SLE) and/or antiphospholipid antibodies (APL) result in an adverse pregnancy outcome (APO) related to abnormal placentation. The ability to identify, early in pregnancy, patients who are destined for poor outcomes would significantly impact care of this high-risk population. In nonautoimmune patients, circulating angiogenic factors are dysregulated in disorders of placentation, such as preeclampsia (PE) and fetal growth restriction. OBJECTIVE: We sought to determine whether early dysregulation of circulating angiogenic factors can predict APO in high-risk SLE and/or APL pregnancies. STUDY DESIGN: We used data and samples from the Predictors of Pregnancy Outcome: Biomarkers in APL Syndrome and SLE (PROMISSE), a multicenter prospective study that enrolled 492 pregnant women with SLE and/or APL from September 2003 through August 2013. Patients were followed through pregnancy from <12 weeks gestation. Circulating levels of soluble fms-like tyrosine kinase-1 (sFlt1), placental growth factor (PlGF), and soluble endoglin were measured monthly and subjects followed up for APO, classified as severe (PE <34 weeks, fetal/neonatal death, indicated preterm delivery <30 weeks) or moderate (PE ≥34 weeks, indicated preterm delivery 30-36 weeks, growth restriction without PE). RESULTS: Severe APOs occurred in 12% and moderate APOs in 10% of patients. By 12-15 weeks, sFlt1, PlGF, and soluble endoglin levels were markedly altered in women who developed severe APO. After adjusting for clinical risk factors, sFlt1 was the strongest predictor of severe APO among 12-15 week measures (odds ratio, 17.3 comparing highest and lowest quartiles; 95% confidence interval [CI], 3.5-84.8; positive predictive value [PPV], 61%; negative predictive value [NPV], 93%). At 16-19 weeks, the combination of sFlt1 and PlGF was most predictive of severe APO, with risk greatest for subjects with both PlGF in lowest quartile (<70.3 pg/mL) and sFlt1 in highest quartile (>1872 pg/mL; odds ratio, 31.1; 95% CI, 8.0-121.9; PPV, 58%; NPV, 95%). Severe APO rate in this high-risk subgroup was 94% (95% CI, 70-99.8%), if lupus anticoagulant or history of high blood pressure was additionally present. In contrast, among patients with both sFlt1 <1872 pg/mL and PlGF >70.3 pg/mL, rate of severe APO was only 4.6% (95% CI, 2.1-8.6%). CONCLUSION: Circulating angiogenic factors measured during early gestation have a high NPV in ruling out the development of severe adverse outcomes among patients with SLE and/or APL syndrome. Timely risk stratification of patients is important for effective clinical care and optimal allocation of health care resources.

Rheumatoid arthritis medications and lactation.

PURPOSE OF REVIEW: In contrast to the disease remission enjoyed by a majority of rheumatoid arthritis (RA) patients during pregnancy, the immediate postpartum period is generally characterized by flare. Managing symptoms during this time is challenging because the potential transfer of medication into the breast milk of nursing mothers may limit which antirheumatic drugs can be safely used. The benefits of breastfeeding are significant, however, so an understanding of how to adjust medications to permit lactation and nursing is important for rheumatologists. RECENT FINDINGS: Although nonsteroidal antiinflammatory drugs (NSAIDs) in general are passed into milk in low doses, shorter acting NSAIDs are preferred, with caution for premature infants. Prednisone can be taken by nursing mothers, although when used at doses higher than 20 mg/day an interval of 4 h after dosing and prior to breastfeeding is recommended. Hydroxychloroquine and sulfasalazine are compatible with nursing. Cyclosporine is generally allowed in lactating women, although a single infant was reported to develop therapeutic drug levels. Azathioprine (AZA) and tissue necrosis factor-α-inhibitors have little to no transfer into breast milk, with negligible levels measured in infant sera, and thus may be considered for use in lactating mothers. Methotrexate and leflunomide should not be used. Other biological RA medications have not been evaluated, and are, therefore, best avoided by breastfeeding patients. SUMMARY: Many but not all RA medications may be used during lactation with low risk to the nursing infant; this review summarizes the available data for commonly used medications in order to help guide therapy during the postpartum period.

Fetal and maternal morbidity in pregnant patients with Lupus: a 10-year US nationwide analysis.

OBJECTIVE: To evaluate and quantify the indicators of fetal and maternal morbidity in deliveries for patients with systemic lupus erythematosus (SLE) compared with deliveries in patients without SLE. METHODS: We used retrospective data from the National Inpatient Sample (NIS) to identify all delivery related hospital admissions of patients with and without SLE from 2008 to 2017 using ICD-9/10 codes. Fetal morbidity indicators included pre-term delivery and intrauterine growth restriction (IUGR). 21 indicators of severe maternal morbidity were identified using standard Centers for Disease Control and Prevention (CDC) definitions. Descriptive statistics, including 95% confidence intervals, were calculated using sample weights from the NIS dataset. RESULTS: Among the 40 million delivery-related admissions, 51 161 patients were reported to have SLE. Patients with SLE had a higher risk of fetal morbidity, including IUGR (8.0% vs 2.7%) and pre-term delivery (14.5% vs 7.3%), than patients without SLE. During delivery, mothers with SLE were nearly four times as likely to require a blood transfusion or develop a cerebrovascular disorder, and 15 times as likely to develop acute renal failure than those without SLE. CONCLUSION: Our study demonstrates that fetal morbidity and severe maternal morbidity occur at a higher rate in patients with SLE compared with those without. This quantitative work can help inform and counsel patients with SLE during pregnancy and planning.

Evaluation of a Patient-reported Frailty Tool in Women With Systemic Lupus Erythematosus.

OBJECTIVE: Frailty is associated with mortality in systemic lupus erythematosus (SLE), but how best to measure frailty is unclear. We aimed to compare 2 frailty metrics, the self-reported Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight (FRAIL) scale (FS) and the Fried phenotype (FP), in SLE to evaluate differences between frail and nonfrail women and whether frailty is associated with self-reported disability. METHODS: Adult women aged < 70 years with validated SLE and mild/moderate disease enrolled in this cross-sectional study between August 2018 and October 2019. Correlation and agreement between the FS and the FP were determined. Differences in sociodemographic and disease characteristics, patient-reported outcome measures (PROMs), and biomarkers between frail and nonfrail participants were evaluated, as well as the association of frailty with Valued Life Activities disability. RESULTS: Of 67 participants, 27% and 18% were frail according to the FS and the FP, respectively. Correlation (r = 0.51; P < 0.0001) and agreement (κ = 0.46; P = 0.0004) between the FS and the FP were significant. Frail women had greater disease damage, high-sensitivity C-reactive protein, and interleukin 6, and worse PROMs according to both frailty definitions. Both frailty measures were associated with self-reported disability after adjustment for age, comorbidity, and disease activity and damage; this relationship was attenuated for the FP. CONCLUSION: Frailty prevalence was high in this cohort of women with SLE using both frailty definitions, suggesting that frailty may be accelerated in women with SLE, particularly when based exclusively on self-report. Frailty remained associated with self-reported disability in adjusted analyses. The FS may be an informative point-of-care tool to identify frail women with SLE.

Contraception and preconception counseling in women with autoimmune disease.

Appropriate contraception and preconception counseling are critical for women of reproductive age with systemic autoimmune diseases (AIDs) because clinical diagnosis, rheumatology medications, and disease activity may impact the safety or efficacy of certain contraceptives as well as the risk of adverse pregnancy outcomes. The presence of antiphospholipid (aPL) antibodies (anticardiolipin, anti-ß2 glycoprotein I, and lupus anticoagulant) is the most important determinant of contraception choice, as women with these antibodies should not receive estrogen-containing contraceptives because of the increased risk of thrombosis. Prepregnancy counseling generally includes the assessment of preexisting disease-related organ damage, current disease activity, aPL antibodies, anti-Ro/SS-A and anti-La/SS-B antibodies, and medication safety in pregnancy. Quiescent AID for six months on pregnancy-compatible medications optimizes maternal and fetal/neonatal outcomes for most patients.

Antiphospholipid syndrome.

Antiphospholipid syndrome is an autoimmune systemic disorder characterized by arterial, venous, or small vessel thrombosis and/or recurrent early pregnancy loss, fetal loss, or pregnancy morbidity in the setting of documented persistent antiphospholipid antibodies that include the lupus anticoagulant, or moderate-high titer anticardiolipin, or anti-ß2Glycoprotein I antibodies. Associated clinical manifestations include livedo reticularis, cutaneous ulcerations, thrombocytopenia, hemolytic anemia, valvular heart disease, and nephropathy. The degree of risk associated with antiphospholipid antibody depends on the characteristics of the antiphospholipid antibody profile and on the presence of additional thrombotic risk factors. Current standard treatment for unprovoked thrombosis is long-term warfarin or other vitamin K antagonist therapy. Treatment to prevent recurrent obstetric complications is low-dose aspirin and prophylactic heparin, usually low-molecular-weight heparin. Optimal treatment for standard therapy failures or for certain nonthrombotic manifestations is uncertain, although nonanticoagulation therapies that address multiple demonstrated mechanisms of disease are being explored.

Responsiveness of the Patient-Reported Outcomes Measurement Information System Global Health Short Form in Outpatients With Systemic Lupus Erythematosus.

OBJECTIVE: To evaluate the longitudinal responsiveness (sensitivity to change) of the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Short Form (PROMIS10) in outpatients with systemic lupus erythematosus (SLE). METHODS: Outpatients with SLE who were receiving care at an academic medical center completed the PROMIS10 at 2 visits that were a minimum of 1 month apart. Responsiveness of the PROMIS10 global physical and mental health domains to Patient-Reported improvement or deterioration of health status was evaluated, as measured by standard validated instruments. Effect sizes of changes in PROMIS10 scores between visits were evaluated using Kruskal-Wallis testing. RESULTS: A total of 223 SLE patients enrolled and completed baseline surveys, with 186 (83.4%) completing a second set of questionnaires. The PROMIS10 demonstrated mild-to-moderate responsiveness to Patient-Reported improvement (effect size 0.29) and worsening (effect sizes -0.27 and -0.54) of health status for both global physical health and global mental health. Changes in the PROMIS10 correlated poorly with changes in physician-reported measures of disease activity. CONCLUSION: The PROMIS10 showed responsiveness over time to Patient-Reported changes in SLE health status, but not physician-assessed changes. These data suggest that the PROMIS10 can be used to efficiently measure and monitor important aspects of the SLE patient experience that are not captured by standard physician-derived metrics. Further studies are needed to evaluate the role of the PROMIS10 in optimizing longitudinal disease management in SLE and to determine its responsiveness in other chronic health conditions.

Low frequency of flares during pregnancy and post-partum in stable lupus patients.

BACKGROUND: Lupus patients are at risk for pregnancy loss, and it has been generally accepted that women with SLE should have low disease activity prior to conception. However, there are conflicting results regarding the effect of pregnancy on SLE flares. This study aims to identify predictors of flares during and after pregnancy in SLE patients with inactive or stable disease activity during the first trimester and to characterize and estimate the frequency of post-partum flares in these patients. METHODS: SLE patients in the multicenter, prospective PROMISSE (Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Antibody Syndrome and Systemic Lupus Erythematosus) study were evaluated for flares during and after pregnancy using the SELENA-SLEDAI Flare Index. Flares during pregnancy were assessed in all 384 patients and post-partum flares in 234 patients with study visits 2-6 months post-partum. Logistic regression models were fit to the data to identify independent risk factors for flare. RESULTS: During pregnancy, 20.8% of patients had mild/moderate flares and 6.25% had severe. Post-partum, 27.7% of patients had mild/moderate flares and 1.7% had severe. The mild flares rarely required treatment. Younger age, low C4 and higher PGA at baseline were independently associated with higher risk of having at least one mild/moderate or severe flare during pregnancy. Older patients were at decreased risk of flare, as well as those with quiescent disease at baseline. No variables evaluated at baseline or the visit most proximal to delivery was significantly associated with risk of flare post-partum. Medications were not associated with flare during or after pregnancy. CONCLUSION: In patients with inactive or stable mild disease activity at the time of conception, lupus disease flares during and after pregnancy are typically mild and occur at similar rates. Flares during pregnancy are predicted by the patients' age and clinical and serological activity at baseline.

2020 American College of Rheumatology Guideline for the Management of Reproductive Health in Rheumatic and Musculoskeletal Diseases.

OBJECTIVE: To develop an evidence-based guideline on contraception, assisted reproductive technologies (ART), fertility preservation with gonadotoxic therapy, use of menopausal hormone replacement therapy (HRT), pregnancy assessment and management, and medication use in patients with rheumatic and musculoskeletal disease (RMD). METHODS: We conducted a systematic review of evidence relating to contraception, ART, fertility preservation, HRT, pregnancy and lactation, and medication use in RMD populations, using Grading of Recommendations Assessment, Development and Evaluation methodology to rate the quality of evidence and a group consensus process to determine final recommendations and grade their strength (conditional or strong). Good practice statements were agreed upon when indirect evidence was sufficiently compelling that a formal vote was unnecessary. RESULTS: This American College of Rheumatology guideline provides 12 ungraded good practice statements and 131 graded recommendations for reproductive health care in RMD patients. These recommendations are intended to guide care for all patients with RMD, except where indicated as being specific for patients with systemic lupus erythematosus, those positive for antiphospholipid antibody, and/or those positive for anti-Ro/SSA and/or anti-La/SSB antibodies. Recommendations and good practice statements support several guiding principles: use of safe and effective contraception to prevent unplanned pregnancy, pre-pregnancy counseling to encourage conception during periods of disease quiescence and while receiving pregnancy-compatible medications, and ongoing physician-patient discussion with obstetrics/gynecology collaboration for all reproductive health issues, given the overall low level of available evidence that relates specifically to RMD. CONCLUSION: This guideline provides evidence-based recommendations developed and reviewed by panels of experts and RMD patients. Many recommendations are conditional, reflecting a lack of data or low-level data. We intend that this guideline be used to inform a shared decision-making process between patients and their physicians on issues related to reproductive health that incorporates patients' values, preferences, and comorbidities.

Longitudinal profiling of human blood transcriptome in healthy and lupus pregnancy.

Systemic lupus erythematosus carries an increased risk of pregnancy complications, including preeclampsia and fetal adverse outcomes. To identify the underlying molecular mechanisms, we longitudinally profiled the blood transcriptome of 92 lupus patients and 43 healthy women during pregnancy and postpartum and performed multicolor flow cytometry in a subset of them. We also profiled 25 healthy women undergoing assisted reproductive technology to monitor transcriptional changes around embryo implantation. Sustained down-regulation of multiple immune signatures, including interferon and plasma cells, was observed during healthy pregnancy. These changes appeared early after embryo implantation and were mirrored in uncomplicated lupus pregnancies. Patients with preeclampsia displayed early up-regulation of neutrophil signatures that correlated with expansion of immature neutrophils. Lupus pregnancies with fetal complications carried the highest interferon and plasma cell signatures as well as activated CD4+ T cell counts. Thus, blood immunomonitoring reveals that both healthy and uncomplicated lupus pregnancies exhibit early and sustained transcriptional modulation of lupus-related signatures, and a lack thereof associates with adverse outcomes.

Combined oral contraceptives in women with systemic lupus erythematosus.

BACKGROUND: Oral contraceptives are rarely prescribed for women with systemic lupus erythematosus, because of concern about potential negative side effects. In this double-blind, randomized, noninferiority trial, we prospectively evaluated the effect of oral contraceptives on lupus activity in premenopausal women with systemic lupus erythematosus. METHODS: A total of 183 women with inactive (76 percent) or stable active (24 percent) systemic lupus erythematosus at 15 U.S. sites were randomly assigned to receive either oral contraceptives (triphasic ethinyl estradiol at a dose of 35 microg plus norethindrone at a dose of 0.5 to 1 mg for 12 cycles of 28 days each; 91 women) or placebo (92 women) and were evaluated at months 1, 2, 3, 6, 9, and 12. Subjects were excluded if they had moderate or high levels of anticardiolipin antibodies, lupus anticoagulant, or a history of thrombosis. RESULTS: The primary end point, a severe lupus flare, occurred in 7 of 91 subjects receiving oral contraceptives (7.7 percent) as compared with 7 of 92 subjects receiving placebo (7.6 percent). The 12-month rates of severe flare were similar: 0.084 for the group receiving oral contraceptives and 0.087 for the placebo group (P=0.95; upper limit of the one-sided 95 percent confidence interval for this difference, 0.069, which is within the prespecified 9 percent margin for noninferiority). Rates of mild or moderate flares were 1.40 flares per person-year for subjects receiving oral contraceptives and 1.44 flares per person-year for subjects receiving placebo (relative risk, 0.98; P=0.86). In the group that was randomized to receive oral contraceptives, there was one deep venous thrombosis and one clotted graft; in the placebo group, there was one deep venous thrombosis, one ocular thrombosis, one superficial thrombophlebitis, and one death (after cessation of the trial). CONCLUSIONS: Our study indicates that oral contraceptives do not increase the risk of flare among women with systemic lupus erythematosus whose disease is stable.
