Idiopathic intracranial hypertension and obstetric and neonatal outcomes: A 1:20 matched study from a population database

OBJECTIVE

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a common pathology in reproductive-aged women, although data regarding pregnancy outcomes are scarce. In the present study, we aimed to compare pregnancy and perinatal outcomes between women who suffered from IIH to those who did not.

METHODS

A retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample. All pregnant women who delivered or had a maternal death in the US (2004-2014) were included. Women with an ICD-9 diagnosis of IIH before or during pregnancy were matched to controls without IIH according to age, race, insurance type, and income quartile, in a 1:20 ratio. Pregnancy, delivery, and neonatal outcomes were compared between the two groups.

RESULTS

Overall, 9 096 788 deliveries were identified. Of these, 1454 women (0.016%) had a diagnosis of IIH (study group) and were compared to 29 080 women without IIH (control group). Women with IIH, compared to those without, were more likely to be obese (body mass index >30 kg/m2) and suffer from pregestational diabetes mellitus and chronic hypertension (P < 0.001, all). After adjusting for confounders, patients in the IIH group, compared to those without, had a higher rate of pregnancy-induced hypertension (aOR 1.82, 95% CI: 1.57-2.1, P < 0.001), pre-eclampsia (aOR 1.98, 95% CI: 1.61-2.45, P < 0.001), preterm delivery (aOR 1.88, 95% CI: 1.59-2.23, P < 0.001), CD (aOR 2.41, 95% CI: 2.12-2.73, P < 0.001), wound complications (aOR 3.2, 95% CI: 1.89-5.42, P < 0.001), and congenital anomalies (aOR 2.18, 95% CI: 1.4-3.4, P < 0.001).

CONCLUSION

Women with IIH had a higher incidence of obstetrical complications, including preterm deliveries, hypertensive disorders of pregnancy, and congenital anomalies.

Roles of IRF4 in various immune cells in systemic lupus erythematosus

Interferon regulatory factor 4 (IRF4) is a member of IRF family of transcription factors which mainly regulates the transcription of IFN. IRF4 is restrictively expressed in immune cells such as T and B cells, macrophages, as well as DC. It is essential for the development and function of these cells. Since these cells take part in the homeostasis of the immune system and dysfunction of them contributes to the initiation and progress of systemic lupus erythematosus (SLE), the roles of IRF4 in the SLE development becomes an important topic. Here we systemically discuss the biological characteristics of IRF4 in various immune cells and analyze the pathologic effects of IRF4 alteration in SLE and the potential targeting therapeutics of SLE.

In Vitro Fertilisation and Systemic Lupus Erythematosus: Making The Correct Choice

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that increases the risk of complications in pregnancy. SLE flares during pregnancy are attributed to higher levels of estrogen and other cytokines. A 34-year-old woman with SLE, who had undergone in vitro fertilization (IVF), was diagnosed with a lupus flare at 14 weeks of gestation. Prior to conception, it is essential to evaluate disease activity, major organ complications, hypercoagulability, and any other medical conditions that could affect pregnancy outcomes in women with SLE in order to prevent adverse results. Additionally, the presence of anti-phospholipid antibodies (APLA) should be ruled out before considering assisted reproductive techniques (ART). After conception, optimal and vigilant monitoring is essential. A multidisciplinary team and approach should be employed throughout pregnancy to manage disease progression and identify any further complications. In conclusion, effective counseling and clear explanations of risks and benefits are pivotal in empowering the patient to make an informed decision.

Adverse Impact of Systemic Lupus Erythematosus on Pregnancy Outcomes: A Saudi Arabia Retrospective Multi-Center Study

Objective

The current study aimed to determine the pregnancy outcomes complications in patients with SLE and its association with clinical, laboratory variables, disease activity, and medication use in the Saudi population, as well as pregnancy effect on disease activity.

Methods

A multicenter study included pregnant female patients with Systemic Lupus Erythematosus (SLE) from three tertiary centers in Saudi Arabia. The demographics, clinical, and laboratory variables, SLE disease activity index (SLEDAI), medication before, during, and after pregnancy, planned pregnancy, pregnancy-related outcomes, and complications in comparison to age-matched healthy female controls were noted.

Results

A total of 66 pregnant patients with SLE and 93 healthy age-matched pregnant controls were included in the study. A total of 77.3% had SLEDAI-2K ≤ 4 before conception, and 84.85% of pregnancies were planned. Age of conception, cesarean section, miscarriage, and low birth weight were statistically significant (p <0.05) higher in SLE patients than in healthy controls. Among all clinical and laboratory variables, SLEDAI-2K > 4 and active lupus nephritis during pregnancy were statistically associated with adverse outcomes (p <0.05), history of lupus nephritis was not associated with statistically adverse pregnancy outcomes. Higher SLEDAI-2K > 4 was an independent risk at least 4.87 times higher association with adverse pregnancy outcomes. (p <0.05).

Conclusion

SLE is intricately connected with unfavorable pregnancy outcomes. The preconception of high disease activity stands as a pivotal risk factor for adverse outcomes. Despite the disease remission and meticulous planning, SLE patients frequently grapple with disease exacerbations during pregnancy, culminating in unexpected and unfavorable pregnancy-related outcomes. This underscores the intricate and multifaceted nature of managing SLE during gestation.

Maternal risk factors for preterm birth in Taiwan, a nationwide population-based cohort study

BACKGROUND

The rate of preterm birth is increasing globally. It causes significant short-term and long-term health care burdens. A comprehensive recognition of the risk factors related to preterm births is important in the prevention of preterm birth. Our study is to investigate the incidence and maternal risk factors of preterm birth from a nationwide population-based perspective.

METHODS

This is a retrospective cohort study. All live births from 2004 to 2014 in Taiwan enrolled. The main data source was Taiwan's Birth Certificate Application (BCA) database. The BCA database was linked with the National Health Insurance Research Database (NHIRD) to establish any links between information on newborns and maternal underlying disease.

RESULTS

A total of 1,385,979 births were included in the analysis. The incidence of preterm birth increased gradually in Taiwan from 8.85% in 2004 to 10.73% in 2014. Maternal age, socioeconomic status, maternal allergy and autoimmune diseases, gynecological diseases, and pregnancy-related complications were significant risk factors for preterm birth.

CONCLUSION

The overall incidence of preterm births has gradually increased in Taiwan. Maternal age, socioeconomic status, certain underlying diseases, and pregnancy-related complications were risk factors for preterm birth.

The risk of pediatric cardiovascular diseases in offspring born to mothers with systemic lupus erythematosus: a nationwide study

Background

Systemic lupus erythematosus (SLE), a common autoimmune disease predominantly affecting women, has been linked to various complications during pregnancy. The transfer of anti-Ro/SSA antibodies from SLE-affected mothers to their offspring can lead to neonatal lupus and cardiac issues. This study investigated the association between maternal SLE and the risk of pediatric cardiovascular disorders.

Methods

The study utilized South Korea's National Health Insurance Service (NHIS) database, covering 3,505,737 children born between 2007 and 2017 and tracked until 2020. Maternal SLE cases were identified using the World Health Organization's International Classification of Diseases Tenth revision (ICD-10) codes and linked with delivery records. Cardiologic disorders were categorized into congenital heart disease (CHD), arrhythmic disorders, and acquired heart disease. Propensity score matching with 1:4 ratios was applied to the set control group.

Results

Among 3,505,737 children, 0.7% (n = 23,330) were born to mothers with SLE. The incidence of preterm birth was significantly higher in the maternal SLE group (5.9% vs. 3.0%). Compared with the control group, children born to mothers with SLE exhibited a significantly elevated risk of overall CHDs (5.5%, adjusted odds ratio [aOR] 1.21; 95% confidence interval [CI] 1.14-1.29), including atrial septal defect (1.18; 1.09-1.28) and patent ductus arteriosus (1.15; 1.03-1.30). In addition, a notably higher risk was observed in arrhythmic disorders (complete atrioventricular block 7.20; 2.41-21.49) and acquired cardiac disorders, including cardiomyopathy (1.40; 1.17-1.68) and mucocutaneous lymph node syndrome (MCLS) (1.27; 1.15-1.43).

Conclusions

Maternal SLE is associated with congenital and acquired cardiac disorders in offspring, including structural, arrhythmic, and MCLS. This study highlights the need for continuous cardiovascular monitoring from the prenatal stage to preadolescence in these children due to multifactorial influences involving maternal autoantibodies, genetic predisposition, and environmental factors.

Maternal and fetal outcomes of SLE in pregnancy: a literature review

Systemic Lupus Erythematosus (SLE) is an auto-immune disease in which the immune system assaults its tissues. We aimed to analyse the maternal and foetal outcomes during pregnancy in SLE mothers. A literature search was conducted by two investigators to assess SLE's outcomes on maternal and foetal during pregnancies. We searched PubMed/Medline, Embase, and Google scholar to collect evidence from different research studies, draw the conclusion, and report it. In our investigation, we found out that SLE could cause a spectrum of complications during pregnancy, not only for the mother but also for the foetus. It could affect fertility and cause difficult pregnancies for the couple as well which includes certain complications such as: preterm labour and delivery, high blood pressure (preeclampsia), placental insufficiency, miscarriage or stillbirth, whereas in the foetus SLE can cause mortality, preterm birth, and neonatal lupus (a temporary condition in the baby caused by SLE-related antibodies) and structural abnormalities. The literature suggests that SLE could prove fatal for the foetus and induce many complications in the mother. However, this could be avoided if pregnancy is planned right from the start and proper management is provided to the mother during pregnancy and delivery.p.

The correlation between pregnancy, disease activity and adverse pregnancy outcomes in patients with systemic lupus erythematosus

OBJECTIVE

In this study, our pregnant systemic lupus erythematosus (SLE) cohort, which was under medical surveillance of both our Rheumatology and Obstetrics departments, was analyzed. We intended to determine the effects of pregnancy on disease activity and the correlation between disease flares and adverse pregnancy outcomes.

METHODS

One hundred sixty eight pregnancy data involving 136 patients with SLE were examined. Cumulative clinical, laboratory, and serological parameters were described. Disease activity and flares were calculated using the systemic lupus erythematosus disease activity index 2000 (SLEDAI-2K) in the pre/postpartum periods and the SLEPDAI in the three trimesters of pregnancy. Patients with a SLEDAI-2K or SLEPDAI ≥ 4 were classified as "active." Patients with lupus low disease activity state (LLDAS) during each of these periods were identified.Fetal/neonatal death, premature birth due to pre-eclampsia, eclampsia or hemolysis, elevated Liver enzymes (HELLP) syndrome, and neonates small for gestational age were determined as adverse pregnancy outcomes (APO).

RESULTS

Out of 168 pregnancies, there were 60 (35.7%) pregnancies with flares covering the pregnancy and 6 months of postpartum period. The mean SLEDAI in the 6 months postpartum period was significantly higher compared to mean disease activity during pregnancy (p < .05). Of all pregnancies, 132 (78.6%) were in LLDAS during pregnancy. Comparison of the frequency of severe postpartum flares in patients who were in LLDAS during pregnancy revealed a lower percentage of flares compared to those who were not in the LLDAS group (11 vs 29%, p < .05). APO was observed in 33.9% of 168 pregnancies. The mean SLEPDAI score was significantly higher in APO+ pregnancies than in APO- pregnancies (4.9 ± 6.1 vs 2.8 ± 4.9, p = .002). Comparison of SLICC damage score between APO - and + pregnancies revealed a significantly higher score in APO+ pregnancies (1.8 ± 2.1 vs 0.8 ± 1.3, p = .001).

CONCLUSION

Postpartum six-month period appears to have the highest risk for disease flares during SLE pregnancies. Disease activity during pregnancy increases the risk of APO. In order to achieve a positive pregnancy outcome and lower maternal morbidity, regular follow-up of patients is necessary.

Pregnancy and Inflammatory Rheumatological Diseases: A Single-Center Retrospective Cohort Study

Background Rheumatic diseases pose risks to pregnant women, leading to complications like preterm birth, congenital heart block, and pregnancy loss. These diseases are expected to deteriorate during pregnancy and further in the postpartum period. The impact of these diseases on the pregnancy will add further burden on the patient, fetus, physician, and healthcare system. Advances in diagnosis and treatment have improved outcomes making them similar to that of healthy women, but close follow-up in a multidisciplinary clinic is essential. The objective of this study is to study the outcome of pregnancy in women with rheumatological disease and the behavior of the disease during pregnancy. Methods A retrospective cohort study was conducted in King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia, to compare the outcomes of pregnancy across three rheumatological diseases: Sjogren syndrome (SS), systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA) from 2016 to 2021. A total of 128 pregnancies in 107 women with rheumatological diseases were included in this study. Pregnancy measures and outcomes were investigated by assessing maternal health, fetal health, and pregnancy complications, specifically maternal disease activity, medications to control the disease, infection, preterm birth, birth weight, abortions/stillbirths, mode of delivery, bleeding, preeclampsia, congenital heart block, and neonatal lupus. Results There were 55 patients with RA (63 RA pregnancies), 44 with SLE (54 SLE pregnancies), and eight with primary SS (11 SS pregnancies). In most of the pregnancies (n= 108; 95.58%), the patients were in clinical remission before pregnancy. Lupus nephritis, which was in remission before pregnancy, has been reported in nine (16.67%) out of 54 SLE pregnancies. Vaginal delivery was the most common mode of delivery (n=87; 67.97%). On the other hand, there were 38 cesarean sections (29.69%). Rheumatological disease flares occurred in 10 pregnancies (7.87%). One hundred and twenty-two live births were delivered. Preterm infants were born in 25 pregnancies (20.16%), and 16 (13.22%) of the newborns needed neonatal intensive care unit (NICU) care. Interestingly, congenital heart block (CHB) was found in five (12.2%) neonates out of 41 anti-SS-related antigen A (anti-SSA) positive mothers; one of those five died from heart block. Eleven neonates were delivered with positive serology, and five were diagnosed with neonatal lupus. Conclusion The outcome of pregnancy in patients with rheumatological disease is favorable. A multidisciplinary team approach and close clinical follow-up are the cornerstone for such success. A small dose of prednisolone (5 mg or less) is safe and will not have a negative impact on maternal or fetal health. CHB is a concern for pregnant women with positive anti-SSA.

Immunobiology of pregnancy: from basic science to translational medicine

Embryo implantation failure and spontaneous abortions represent the main causes of infertility in developed countries. Unfortunately, incomplete knowledge of the multiple factors involved in implantation and fetal development keeps the success rate of medically assisted procreation techniques relatively low. According to recent literature, cellular and molecular mechanisms of 'immunogenic tolerance' towards the embryo are crucial to establish an 'anti-inflammatory' state permissive of a healthy pregnancy. In this review we dissect the role played by the immune system in the endometrial-embryo crosstalk, with a particular emphasis towards the fork-head-box-p3 (Foxp3+) CD4+CD25+ regulatory T (Treg) cells and discuss the most recent therapeutic advances in the context of early immune-mediated pregnancy loss.

Feto-maternal outcomes of pregnancies in women with SLE: Experience from a tertiary care center of Asia

OBJECTIVE

We aim to quantify the risk of maternal and fetal complications in patients with SLE in order to identify the impact of SLE on pregnancy and of pregnancy on SLE.

METHODS

This retrospective record review study was conducted in Aga khan university hospital, Karachi, from Jan 1998 to Dec 2019. All pregnant patients with SLE diagnosed and delivered during this time were included in the study. Categorical variables were analyzed by using chi-square test and fisher exact test. Whereas quantitative point estimate was estimated as mean and SD. We matched the data and computed crude odds ratio of pre-eclamptic patients with respect to age of conception, gravida, and body mass index in both case and control group.

RESULTS

The SLE disease activity was monitored during pregnancy under SLEDAI-2K Scoring system. The patients with mild (25.6%) and moderate (25.6%) disease activity were prevalent and most antenatal patients (51.7%) had flare up in third trimester. Adverse maternal outcomes include pre-eclampsia (28.8%), eclampsia (3.2%), cesarean section (57.6%), and thrombocytopenia (9.6%), whereas perinatal outcomes includes intrauterine growth retardation (24%), preterm birth <34 weeks (19.2%) and <37 weeks (63.2%), APGAR Score < 7 at 1 min (5.6%), and neonatal death (5.6%) found to be statistically significant in between two groups There were more high-risk patients (42) with positive IgG (88%), IgM (83.3%), and lupus anticoagulant (33.3%) as compared to low-risk APS group.

CONCLUSION

Planned pregnancy and less severe disease flares during pregnancy is associated with more favorable feto-maternal outcomes.

The Role of the Interleukin-1 Family in Complications of Prematurity

Preterm birth is a major contributor to neonatal morbidity and mortality. Complications of prematurity such as bronchopulmonary dysplasia (BPD, affecting the lung), pulmonary hypertension associated with BPD (BPD-PH, heart), white matter injury (WMI, brain), retinopathy of prematurity (ROP, eyes), necrotizing enterocolitis (NEC, gut) and sepsis are among the major causes of long-term morbidity in infants born prematurely. Though the origins are multifactorial, inflammation and in particular the imbalance of pro- and anti-inflammatory mediators is now recognized as a key driver of the pathophysiology underlying these illnesses. Here, we review the involvement of the interleukin (IL)-1 family in perinatal inflammation and its clinical implications, with a focus on the potential of these cytokines as therapeutic targets for the development of safe and effective treatments for early life inflammatory diseases.

Maternal Near Miss in Patients with Systemic Lupus Erythematosus

OBJECTIVE

 Systemic lupus erythematosus (SLE) may cause irreversible organ damage. Pregnancy with SLE may have severe life-threatening risks. The present study aimed to determine the prevalence of severe maternal morbidity (SMM) in patients with SLE and analyze the parameters that contributed to cases of greater severity.

METHODS

This is a cross-sectional retrospective study from analysis of data retrieved from medical records of pregnant women with SLE treated at a University Hospital in Brazil. The pregnant women were divided in a control group without complications, a group with potentially life-threatening conditions (PLTC), and a group with maternal near miss (MNM).

RESULTS

 The maternal near miss rate was 112.9 per 1,000 live births. The majority of PLTC (83.9%) and MNM (92.9%) cases had preterm deliveries with statistically significant increased risk compared with the control group (p = 0.0042; odds ratio [OR]: 12.05; 95% confidence interval [CI]: 1.5-96.6 for the MNM group and p = 0.0001; OR: 4.84; 95%CI: 2.2-10.8 for the PLTC group). Severe maternal morbidity increases the risk of longer hospitalization (p < 0.0001; OR: 18.8; 95%CI: 7.0-50.6 and p < 0.0001; OR: 158.17; 95%CI: 17.6-1424,2 for the PLTC and MNM groups, respectively), newborns with low birthweight (p = 0.0006; OR: 3.67; 95%CI: 1.7-7.9 and p = 0.0009; OR: 17.68; 95%CI: 2-153.6) for the PLTC and MNM groups, respectively] as well as renal diseases (PLTC [8.9%; 33/56; p = 0.0069] and MNM [78.6%; 11/14; p = 0.0026]). Maternal near miss cases presented increased risk for neonatal death (p = 0.0128; OR: 38.4; 95%CI: 3.3-440.3]), and stillbirth and miscarriage (p = 0.0011; OR: 7.68; 95%CI: 2.2-26.3]).

CONCLUSION

 Systemic lupus erythematosus was significantly associated with severe maternal morbidity, longer hospitalizations, and increased risk of poor obstetric and neonatal outcomes.

Pregnancy in lupus: an updated consensus to guide best practice strategies

Background

Systemic lupus erythematosus is a multifaceted chronic relapsing autoimmune disease of unknown etiology. The disease has always been a serious diagnosis in women being a multisystem pathology that is classically encountered during the childbearing age posing serious systemic comorbidities with a potential impact on the functional performance, psychosocial status, and survival. In this article, we review critical issues related to the decision to conceive in female with lupus highlighting the impact of the diagnosis and disease activity status on the mother and the fetus, attempting to suggest a consensus to guide safe decision making for pregnancy with SLE.

Main body

The pleomorphic dysregulated immune nature of lupus in the presence of uncontrolled disease carries a higher risk of complicated pregnancy. Therefore, SLE pregnancies should be well planned and are usually encouraged if the disease is inactive (at least 6 months prior to conception) to ensure immune quiescence towards a safer outcome.

Conclusion

With the proper implementation of preconception counseling strategy, choice of the correct timing of conception, close monitoring of SLE flares with tight control, and the appreciation of the value of multidisciplinary management to best practice most young women with SLE can carry on successful pregnancies with favorable outcome.

Pregnancy Outcomes in Undifferentiated Connective Tissue Disease Compared to Systemic Lupus Erythematosus: A Single Academic Center's Experience

OBJECTIVE

Systemic lupus erythematosus (SLE) patients have more pregnancy complications than healthy patients. Data regarding pregnancy outcomes in women with undifferentiated connective tissue disease (UCTD) are more limited, and existing studies are concentrated in Italy and predominantly in patients with a new diagnosis. Our objective was to compare pregnancy outcomes for UCTD and SLE patients with established disease.

METHODS

Between 2008 and 2017, patients with UCTD and SLE at an academic medical center were recruited to a prospective pregnancy registry. UCTD was defined as a positive autoantibody plus connective tissue disease symptoms not meeting criteria for another rheumatic diagnosis. SLE was defined by American College of Rheumatology or Systemic Lupus International Collaborating Clinics classification criteria or by physician diagnosis. Data were collected throughout pregnancy and postpartum. Comparator groups included UCTD, low-activity SLE, and high-activity SLE.

RESULTS

A total of 150 SLE and 51 UCTD pregnancies were analyzed. Disease activity was low in most patients, although more patients with SLE had severe activity during pregnancy (12% versus 2%; P = 0.05). The frequencies of prematurity and preeclampsia were significantly lower in UCTD than in high-activity SLE patients (preterm 17% versus 45% [P = 0.004] and preeclampsia 6% versus 34% [P = 0.0008]), although similar to low-activity SLE patients. More infants who were small for gestational age were born to SLE than UCTD patients (33% versus 7% [P = 0.0005]), regardless of disease activity level.

CONCLUSION

Pregnancies in women with UCTD managed by a rheumatologist have a high rate of pregnancy success and fewer risks than those in women with active SLE.

Pre-eclampsia: a Scoping Review of Risk Factors and Suggestions for Future Research Direction

Abstract

Most of maternal deaths are preventable, and one-quarter of maternal deaths are due to pre-eclampsia and eclampsia. Prenatal screening is essential for detecting and managing pre-eclampsia. However, pre-eclampsia screening is solely based on maternal risk factors and has low (< 5% in the USA) detection rates. This review looks at pre-eclampsia from engineering, public health, and medical points of view. First, pre-eclampsia is defined clinically, and the biological basis of established risk factors is described. The multiple theories behind pre-eclampsia etiology should serve as the scientific basis behind established risk factors for pre-eclampsia; however, African American race does not have sufficient evidence as a risk factor. We then briefly describe predictive statistical models that have been created to improve screening detection rates, which use a combination of biophysical and biochemical biomarkers, as well as aspects of patient medical history as inputs. Lastly, technologies that aid in advancing pre-eclampsia screening worldwide are explored. The review concludes with suggestions for more robust pre-eclampsia research, which includes diversifying study sites, improving biomarker analytical tools, and for researchers to consider studying patients before they become pregnant to improve pre-eclampsia detection rates. Additionally, researchers must acknowledge the systemic racism involved in using race as a risk factor and include qualitative measures in study designs to capture the effects of racism on patients.

Lay Summary

Pre-eclampsia is a pregnancy-specific hypertensive disorder that can affect almost every organ system and complicates 2-8% of pregnancies globally. Here, we focus on the biological basis of the risk factors that have been identified for the condition. African American race currently does not have sufficient evidence as a risk factor and has been poorly studied. Current clinical methods poorly predict a patient's likelihood of developing pre-eclampsia; thus, researchers have made statistical models that are briefly described in this review. Then, low-cost technologies that aid in advancing pre-eclampsia screening are discussed. The review ends with suggestions for research direction to improve pre-eclampsia screening in all settings.Overall, we suggest that the future of pre-eclampsia screening should aim to identify those at risk before they become pregnant. We also suggest that the clinical standard of assessing patient risk solely on patient characteristics needs to be reevaluated, that study locations of pre-eclampsia research need to be expanded beyond a few high-income countries, and that low-cost technologies should be developed to increase access to prenatal screening.

Maternal disease activity and serological activity as predictors of adverse pregnancy outcomes in women with systemic lupus erythematosus: a retrospective chart review

PURPOSE

To evaluate the association between disease activity, serological activity, and adverse pregnancy outcomes (APOs) in women with systemic lupus erythematosus (SLE) and determine the cut-off values of complements to predict APOs in live birth cases.

METHODS

This retrospective chart review included pregnant women with SLE who had singleton live births after 22 weeks between 2006 and 2020. First trimester maternal disease activity was assessed for SLE onset during pregnancy, antiphospholipid syndrome, SLE pregnancy disease activity index (SLEPDAI), disease flare-ups, lupus nephritis, pancytopenia, and daily prednisolone dosage. Serological activity was assessed for autoantibodies and complements. APOs included preterm birth (PTB), low birth weight infants, small-for-gestational age infants, preterm premature rupture of membranes, and preeclampsia (PE). Chi-square and Fisher's exact tests were used to compare categorical variables; a receiver-operating characteristic analysis was performed to calculate the cut-off values of complements to predict APOs.

RESULTS

Fifty-two participants met the inclusion criteria. The incidence of PTB and PE was associated with a high SLEPDAI (p < 0.001, p = 0.001), disease flare-ups (p = 0.007, p < 0.001), lupus nephritis (p = 0.020, p = 0.012), anti-dsDNA antibodies (p = 0.047, p = 0.016), anti-SSA antibodies (p = 0.003, p = 0.004), low CH 50 (p < 0.001, p < 0.001), low C3 (p < 0.001, p < 0.001), and low C4 (p < 0.001, p = 0.001), respectively. The cut-off values of C4 to predict PTB and PE were 13.0 mg/dL (higher than the normal lowest limit).

CONCLUSION

High maternal disease activity and high serological activity in the first trimester in women with SLE are significantly associated with APOs. Proper disease control and close management for hypocomplementemia are required for better perinatal outcomes.

Disease Activity and Rate and Severity of Flares During Peripartum Period in Thai Patients With Systemic Lupus Erythematosus: An Age at Diagnosis and Disease Duration Matched Controlled Study

BACKGROUND/OBJECTIVE

The aim of this study was to compare disease activity and rate and severity of flares between pregnant and nonpregnant systemic lupus erythematosus (SLE) patients.

METHODS

Medical records of pregnant SLE patients seen between January 1993 and June 2017 were reviewed. Nonpregnant SLE controls were matched by age at diagnosis and disease duration before pregnancy. Systemic lupus erythematosus disease activity and flares were determined by the cSLEDAI (clinical Systemic Lupus Erythematosus Disease Activity Index) and Safety of Estrogens in Lupus Erythematosus National Assessment-SLEDAI Flare Index, respectively. Disease activity was measured from 6 months before conception (-6 months) until the postpartum period. The repeated measures mixed model, Cox regression, and cumulative hazard plots were used for statistical analysis.

RESULTS

Ninety pregnancies occurred in 77 patients. The cSLEDAI scores from -6 months to the postpartum period were comparable between the pregnancy and control group, but slightly yet significantly higher in the controls at conception (mean ± SEM, 3.57 ± 0.45 vs 1.90 ± 0.36; p = 0.019). When compared with the controls, during the pregnancy and postpartum period, the pregnancy group did not have significantly higher incidence of flare (41.11% vs 28.89%, p = 0.086 and 7.78% vs 11.11%, p = 0.445, respectively) or flare category (severe flare) (75.68% vs 53.85%, p = 0.070 and 85.71% vs 70.00%, p = 0.603, respectively). The flare incidence rate (95% confidence interval)/100 patient-months in the pregnancy and control group was 6.75 (4.89-9.32) and 4.34 (2.96-6.38), respectively, giving the adjusted hazards for flare (95% confidence interval) of 1.54 (0.91-2.61) (p = 0.110).

CONCLUSIONS

There was no overall significant increase in SLE disease activity, flare incidence, and flare severity in pregnant SLE patients when compared with their properly matched nonpregnant SLE controls.

Quality of Life of Pregnant Women with Systemic Lupus Erythematosus

OBJECTIVE

 To assess the quality of life (QoL) of pregnant women with systemic lupus erythematosus (SLE) treated at a high-risk prenatal outpatient clinic during the third trimester of gestation.

METHODS

 An observational descriptive study was performed in a high-risk prenatal outpatient clinic. Women in the third trimester of pregnancy and undergoing antenatal care between July 2017 and July 2019 answered the abbreviated World Health Organization Quality of Life (WHOQOL-BREF) questionnaire, consisting of 26 questions divided into 4 domains (physical, psychological, social and environmental).

RESULTS

 We interviewed 50 pregnant women with a mean gestational age of 30 weeks (standard deviation [SD]: 10 weeks) who were diagnosed with SLE. The average age of the participants was 30 years (SD: 14.85), and the average time since the diagnosis of SLE was of 9.06 years (SD: 6.8 years). Most participants had a partner, did not plan their pregnancy (76%), and did not use contraception prior to pregnancy (80%). The score of each domain ranges from 0 (the worst score) to 100 (the best score). The means ±  SDs of the scores of the participants on each domain were: physical - 52.21 ±  18.44); psychological - 64.17 ±  18.56); social - 66.33 ±  27.09); and environmental - 64.56 (18.53). The means ±  SDs of the general QoL, and health-related QoL items were of 70.50 ±  24.06 and 70.00 ±  30.72 respectively.

CONCLUSION

 The physical domain presented the lowest scores compared with the other three domains. Pregnant women with SLE had high overall QoL scores, and their health-related QoL scores were also relatively high.

Catch-up growth of infants born to mothers with autoimmune rheumatic disorders

BACKGROUND

In women with autoimmune rheumatic disorders (ARD), pregnancy complications or postpartum events are more frequent compared to the general population. Transplacental autoantibodies or cytokines influence various fetal and neonatal outcomes. We compared the growth patterns of babies born to mothers with ARD versus healthy mothers to assess the long-term growth outcomes of children born to women with ARD.

METHODS

This was a retrospective age-matched cohort analyses of babies born to mothers with ARD from the hospitals belonging to the Catholic University of Korea between 2010 and 2017. Demographic and autoimmune laboratory test data of the mothers and newborns were assessed. Neonatal growth was measured in terms of height and weight, measured at birth and follow-up examinations.

RESULTS

We enrolled 142 infants from mothers with ARD and 149 infants from healthy mothers. There was no significant difference between mothers with ARD and healthy mothers in terms of delivery age, parity, abortion, and premature delivery history. The mothers with ARD were diagnosed with systemic lupus erythematosus (81%), Sjogren syndrome (6%), and other autoimmune phenomena (11%). The groups were significantly different in terms of neonatal characteristics such as prematurity, gestational age, birth weight, and height, but not in Apgar score and delivery type. For most neonates, autoimmune laboratory results were normalized within 1 year, except for anti-La/SSB antibody, which remained high in some. The height and weight for age z-score were lower than the normal age groups at birth but showed catch-up growth by 2 years of age.

CONCLUSIONS

Low birthweight and prematurity at birth for neonates born to mothers with ARD could be caught up by 2 years of age, and maternal ARD does not affect the growth of their offspring.

Pregnancy and systemic lupus erythematosus in Spain: Has anything changed in the 21st century?

OBJECTIVE

To analyse a cohort of pregnant patients with systemic lupus erythematosus and compare the outcomes of both the disease and pregnancy with the results of previous studies conducted in the same geographical area.

PATIENTS AND METHODS

Retrospective cohort study of 37 women with systemic lupus erythematosus (64 pregnancies) followed in a multidisciplinary unit. Comparative study with similar Spanish studies identified after literature search.

RESULTS

Our cohort was characterized by an older age and by the presence of non-Caucasian patients. Although we found no clinical differences, from the serological point of view our cohort presented a higher frequency of antiphospholipid antibodies. Patients included in this study were treated more frequently with antimalarials and low-dose aspirin. Systemic lupus erythematosus flare frequency was very similar between the different studies, and we did not identify clear predictors for them. Although the rate of live births was similar among studies, the obstetric outcome of our series was better with a very low rate of preeclampsia, preterm birth and low birth weight newborn. The only predictor of adverse obstetric event was age.

CONCLUSIONS

Although changes in the therapeutic attitude and planning of pregnancy in recent years have not had a direct impact on the rate of systemic lupus erythematosus flares during pregnancy, they have meant an improvement in the obstetric results. The introduction of new variables independent of the disease such as age at conception, socio-cultural origin, or the availability of multidisciplinary units should be considered in the results of future studies.

Pregnancy outcomes between pregnant systemic lupus erythematosus patients with clinical remission and those with low disease activity: A comparative study

Objectives

This study aims to compare pregnancy outcomes between systemic lupus erythematosus (SLE) patients who attained clinical remission based on the Definition of Remission in SLE (DORIS) and those with lupus low disease activity based on Low Lupus Disease Activity State (LLDAS).

Patients and methods

Between January 1993 and June 2017, a total of 90 pregnancies (one twin pregnancy) from 77 patients (mean age: 26.9±4.8 years; range, 17.9 to 37.3 years) were included in the study. The clinical remission and the LLDAS groups were modified into modified clinical remission and LLDAS groups, respectively by omitting Physician Global Assessment (PGA). The clinical SLE disease activity index (cSLEDAI) score was used for LLDAS.

Results

Pregnancies in 49 patients occurred, when they were in modified clinical remission and in 57 in modified LLDAS. There was no significant difference in demographic characteristics, disease activity, or medication received at conception between the two groups. Pregnancy outcomes were similar between the modified clinical remission and the modified LLDAS groups in terms of successful pregnancy (83.67% vs. 84.21%), full-term births (38.78% vs. 38.60%), fetal losses (16.33% vs. 15.79%), spontaneous abortions (14.29% vs. 14.04%), small for gestational age infants (18.37% vs. 19.30%), low birth weight infants (42.86% vs. 40.35%), maternal complications (46.94% vs. 49.12%), and maternal flares (36.73% vs. 40.35%). The agreement of pregnancy outcomes was very high between the two groups (91.11% agreement).

Conclusion

Pregnancy outcomes in SLE patients who achieved modified clinical remission and modified LLDAS were comparable.

High-risk factors for adverse pregnancy outcomes in systemic lupus erythaematosus: a retrospective study of a Chinese population

OBJECTIVE

To clarify high-risk factors for adverse pregnancy outcomes (APOs) in systemic lupus erythaematosus (SLE).

DESIGN

A retrospective chart review study.

SETTING

Data were collected in a tertiary medical centre, Shanghai, China, from November 2010 to December 2018.

PARTICIPANTS

A total of 513 pregnancies with SLE were retrospectively analysed. Twenty-seven patients who underwent artificial abortions due to personal reasons were excluded.

PRIMARY OUTCOME MEASURES

APOs were primary outcomes, including foetal loss, premature birth, small for gestational age (SGA), asphyxia neonatorum, composite foetal APOs and hypertensive disorders of pregnancy (HDP). Multivariable logistic regression and Spearman correlation analysis were performed to determine the risk factors for APOs in SLE.

RESULTS

Risk factors for foetal loss included prepregnancy hypertension, hypocomplementaemia-C3, anticardiolipin antibodies-IgM positivity and disease flares during pregnancy. Risk factors for premature birth included disease flares, use of immunosuppressive agents and HDP. Moreover, twin pregnancy, disease flares and HDP were risk factors for SGA, and prepregnancy hypertension was an independent risk factor for asphyxia neonatorum. Independent risk factors for composite foetal APOs included twin pregnancy, prepregnancy hypertension, disease flares during pregnancy, HDP, hypocomplementaemia-C3 and the use of immunosuppressive agents. Risk factors for SLE complicated with HDP included prepregnancy hypertension, renal disorders and thrombocytopaenia. Conversely, the use of aspirin was a protective factor against foetal loss and premature birth. The ds-DNA value had a low diagnostic value for APOs, whereas the extent of complement reduction may predict the incidence of composite foetal APOs and foetal loss. Proteinuria occurring in the first 20 gestational weeks may lead to APOs.

CONCLUSION

Established risk factors for each APO were identified in this study. Indicators with more predictive significance have been screened out from conventional indicators, which may help clinicians predict the pregnancy outcome of patients with SLE more accurately and minimise the incidence of APOs.

Systemic lupus erythematosus and pregnancy: A retrospective single-center study of 215 pregnancies from Portugal

OBJECTIVE

Systemic lupus erythematosus (SLE) is a life-threatening disorder that affects women at reproductive age. We evaluate the clinical impact of pregnancy in a cohort of Portuguese SLE patients and the risk factors associated with maternal and fetal adverse outcomes.

METHODS

A retrospective observational study that included all pregnant women with SLE managed at a Portuguese tertiary hospital, between January 1993 and December 2019. Baseline maternal information was collected, and maternal-fetal and neonatal outcomes were evaluated. Disease activity before and during pregnancy was assessed.

RESULTS

We included 215 pregnancies from 143 patients. Lupus nephritis was present in 20.0% and antiphospholipid syndrome (APS) in 21.9% of the cases. Preconception consultation was performed in 86.9% of the pregnancies, and 92.5% of the patients had no or low disease activity at conception. During gestation, 79.6% of the patients were under treatment, and hydroxychloroquine (HCQ) was the most commonly used drug (63.7%). Low-dose acetylsalicylic acid (ASA) was prescribed at conception in 87.9% of the patients. The live birth rate was 84.2%. An adverse pregnancy outcome (APO) occurred in 41.4% of the pregnancies. A miscarriage rate of 15.3% and a preterm delivery rate of 15.4% were found. Preeclampsia and fetal growth restriction complicated 13.1% and 14.0% of the gestations, respectively. Neonatal lupus occurred in 7.1% of the newborns, and there were 2 cases of congenital heart block. Significant risk factors for the development of AOP were disease activity at conception, lupus flare, hypocomplementemia, positivity for lupus anticoagulant, and APS. The use of ASA was significantly associated with a reduced incidence of miscarriage. An SLE flare was diagnosed in 16.3% of the cases. We identified as risk factors for lupus flares the presence of active disease at conception, a previous history of lupus nephritis, and the use of chronic medication. HCQ use during pregnancy was associated with a significant reduction of flare incidence during pregnancy and postpartum.

CONCLUSIONS

Pregnancy in an SLE patient is associated with an increased incidence of adverse obstetric outcomes. Good disease control before pregnancy and adequate treatment, especially with HCQ, is crucial to achieving the best obstetric results.

Pregnancy Outcomes in Systemic Lupus Erythematosus Women: A single tertiary centre experience

Objectives

This study was conducted to assess pregnancy outcomes in women with systemic lupus erythematosus (SLE) in Oman.

Methods

A retrospective cohort study of 149 pregnancies in 98 women with SLE was conducted over 10 years to evaluate the impact of clinical and laboratory parameters in predicting adverse pregnancy outcomes.

Results

Mean maternal age was 30.6 ± 5 years ranging from 20–44 years, and the mean disease duration was 10 ± 5 years, ranging from 2–27 years. The most common maternal manifestations were joint pain in 36 (24.2%), lupus nephritis (LN) in 18 (12.08%), preeclampsia in 11 (7.4%), eclampsia in three (2%) and lupus flare in one pregnancy. The live birth rate was 139 (93.3%) with a mean gestational age of 36 ± 2 weeks ranging from 26–40 weeks. In total, 55 (39.6%) were preterm deliveries, six (4%) pregnancies ended in miscarriage, and four (2.7%) resulted in intrauterine fetal death. Intrauterine growth restriction was observed in 49 babies (35%). A significant association was found between hypertension (HTN) and miscarriage (P = 0.024) and preterm birth (P = 0.019). In addition, HTN was positively associated with preeclampsia (P = 0.004) and LN (P = 0.048). Antiphospholipid syndrome impacted preterm birth (P = 0.013) and postpartem haemorrhage (PPH) (P = 0.027) and was found to be a significant predictor for women developing deep vein thrombosis and pulmonary embolism (P <0.001 for both).

Conclusion

Despite potential complications, most pregnancies complicated by SLE in Oman result in good outcomes. Adverse pregnancy outcomes, however, may still occur in women with SLE. In women with SLE, pregnancy planning, careful antenatal monitoring and efficient SLE treatment need to be undertaken for successful pregnancy outcomes.

Outcomes of pregnancy and childbirth in women with hidradenitis suppurativa

BACKGROUND

Many women affected by hidradenitis suppurativa (HS) are of childbearing age. To date, the literature is limited on pregnancy-related outcomes for women with HS.

OBJECTIVE

To investigate maternal and obstetric outcomes and treatment utilization among women with HS.

METHODS

This retrospective analysis used the IBM MarketScan Commercial Claims Database. Pregnant women with HS (n = 998) and 5:1 age-matched pregnant women without HS (n = 5065) were identified and information on claims related to diagnoses, procedures, and medications were analyzed.

RESULTS

Compared to women without HS, pregnant women with HS had significantly lower odds of having a live birth (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.39-0.51) and significantly higher odds of having elective terminations (OR, 2.51; 95% CI, 2.13-2.96), gestational hypertension (OR, 1.44; 95% CI, 1.12-1.84), and cesarean deliveries (OR, 1.28; 95% CI, 1.06-1.55), and of receiving HS designated treatment during pregnancy (OR, 4.41; 95% CI, 3.56-5.46).

LIMITATIONS

Retrospective and convenience sampling and absence of clinical information to correlate HS severity and outcomes.

CONCLUSION

Pregnant women with HS have an increased probability of select complicated maternal and obstetric outcomes. Women planning for pregnancy or who are currently pregnant may benefit from coordinated care by dermatologists and obstetric providers.

Management of Pregnancy in Lupus

Systemic lupus erythematosus (SLE) is an autoimmune disease that primarily affects women of childbearing age. Pregnancy-related morbidity and mortality are well described in SLE; however, better management of disease activity throughout the disease course have minimized periods of disease activity and damage accrual, making pregnancy more feasible and desirable. A growing body of literature has defined risk factors for adverse pregnancy outcomes in patients with SLE, and coordinated medical and obstetric management has allowed most patients with SLE to safely achieve full-term pregnancies by timing pregnancy to maximal disease quiescence and use of pregnancy-compatible medications from preconception through lactation.

Outcomes of pregnancy and associated factors in sub-Saharan African women with systemic lupus erythematosus: a scoping review

Objective

To scope and summarise available literature on the outcomes of pregnancy and associated factors in sub-Saharan African women with SLE.

Methods

Electronic databases and reference lists of retrieved articles were searched to identify relevant studies published from 1 January 2000 to 28 October 2019. Data were combined through narrative synthesis.

Results

We included four studies retrospectively reporting a total of 137 pregnancies in 102 women over a 26-year period. Mean age at conception ranged from 27.2 to 39.9 years. Kidney damage, the predominant organ manifestation before conception, was reported in 43 (42.2%) patients. Ninety-seven (70.8%) pregnancies resulted in 98 live births. SLE flares occurred in 44 (32.2%) pregnancies, mainly skin (20.4%) and renal (18.2%) flares. Major adverse pregnancy outcomes (APOs) were preterm birth 38.8%, low birth weight 29.8%, pregnancy loss 29.2% and pre-eclampsia 24.8%. The main factors associated with APOs were nephritis and SLE flares.

Conclusion

Over two-thirds of pregnancies resulted in live birth in this cohort of sub-Saharan African women with SLE. The main APOs and associated factors described in other parts of the world are also seen in this region, but with high rates of APOs. A large prospective multinational study is warranted for more compelling evidence.

Soluble Flt-1, Placental Growth Factor, and Vascular Endothelial Growth Factor Serum Levels to Differentiate Between Active Lupus Nephritis During Pregnancy and Preeclampsia

OBJECTIVE

To evaluate mean serum levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), and soluble Flt-1 (sFlt-1) in pregnant patients with systemic lupus erythematosus (SLE) with inactive disease, active lupus nephritis, and preeclampsia for differential diagnosis between these conditions.

METHODS

Pregnant women with SLE, with singleton pregnancies and no other autoimmune diseases, were classified according to disease activity (inactive SLE and active lupus nephritis) and the presence of preeclampsia. Serum samples were collected within 3 weeks of delivery and frozen for subsequent blinded analysis through the enzyme-linked immunosorbent assay method.

RESULTS

A total of 71 women were included, with 41 classified as having inactive SLE (group 1; Systemic Lupus Erythematosus Pregnancy Disease Activity Index [SLEPDAI] score <4), 15 with a diagnosis of active lupus nephritis (group 2, SLEPDAI score ≥4, including renal criteria), and 15 with a diagnosis of preeclampsia (group 3). Patients in group 3 had higher mean levels of sFlt-1 and lower mean levels of PlGF compared to groups 1 and 2, both findings with statistical significance. The sFlt-1:PlGF ratio was also significantly higher in patients with preeclampsia, while mean VEGF levels were higher in pregnant woman with active lupus nephritis compared to patients with preeclampsia or inactive SLE.

CONCLUSION

Evaluation of serum VEGF, PlGF, and sFlt-1 levels can differentiate between preeclampsia, inactive SLE, and active lupus nephritis during pregnancy.

Shedding light on the pathophysiology of preeclampsia-syndrome in the era of Cardio-Obstetrics: Role of inflammation and endothelial dysfunction

:

Preeclampsia (PE) is a worldwide pregnancy complication with serious maternal and neonatal consequences. Our understanding of PE pathophysiology has significantly evolved over the last decades by recognizing that endothelial dysfunction and systemic inflammation, with an associated angiogenic imbalance, are key pieces of this still incomplete puzzle. In the present era, where no single treatment to cure or treat this obstetric condition has been developed so far, PE prevention and early prediction poses the most useful clinical approach to reduce the PE burden. Although most PE episodes occur in healthy nulliparous women, the identification of specific clinical conditions that increase dramatically the risk of PE provides a critical opportunity to improve outcomes by acting on potential reversible factors, and also contribute to better understand this pathophysiologic enigma. In this review, we highlight major clinical contributors of PE and shed light about their potential link with endothelial dysfunction and inflammation.

Predicting factors of adverse pregnancy outcomes in Thai patients with systemic lupus erythematosus: A STROBE-compliant study

Studies on predicting factors for adverse pregnancy outcomes (APOs) in Thai patients with systemic lupus erythematosus (SLE) are limited. This retrospective observation study determined APOs and their predictors in Thai patients with SLE.Medical records of pregnant SLE patients in a lupus cohort, seen from January 1993 to June 2017, were reviewed.Ninety pregnancies (1 twin pregnancy) from 77 patients were identified. The mean age at conception was 26.94 ± 4.80 years. At conception, 33 patients (36.67%) had active disease, 23 (25.56%) hypertension, 20 (22.22%) renal involvement, and 6 of 43 (13.95%) positive anti-cardiolipin antibodies or lupus anti-coagulants, and 37 (41.11%) received hydroxychloroquine. Nineteen patients (21.11%) had pregnancy loss. Of 71 successful pregnancies, 28 (31.11%) infants were full-term, 42 (46.67%) pre-term and 1 (11.11%) post-term; 19 (26.39%) were small for gestational age (SGA), and 38 (52.58%) had low birth weight (LBW). Maternal complications occurred in 21 (23.33%) pregnancies [10 (11.11%) premature rupture of membrane (PROM), 8 (8.89%) pregnancy induced hypertension (PIH), 4 (4.44%) oligohydramnios, 2 (2.22%) post-partum hemorrhage, and 1 (1.11%) eclampsia]. Patients aged ≥ 25 years at pregnancy and those ever having renal involvement had predicted pregnancy loss with adjusted odds ratio (AOR) [95% CI] of 4.15 [1.10-15.72], P = .036 and 9.21 [1.03-82.51], P = .047, respectively. Renal involvement predicted prematurity (6.02 [1.77-20.52, P = .004), SGA (4.46 [1.44-13.78], P = .009), and LBW in infants (10.01 [3.07-32.62], P < .001). Prednisolone (>10 mg/day) and immunosuppressive drugs used at conception protected against prematurity (0.11 [0.02-0.85], P = .034). Flares and hematologic involvement predicted PROM (8.45 [1.58-45.30], P = .013) and PIH (9.24 [1.70-50.24], P = .010), respectively. Cutaneous vasculitis (33.87 [1.05-1,094.65], P = .047), and renal (31.89 [6.66-152.69], P < .001), mucocutaneous (9.17 [1.83-45.90], P = .007) and hematologic involvement (128.00 [4.60-3,564.46], P = .004) during pregnancy predicted flare; while prednisolone (>10 mg/day) and immunosuppressive drug use at conception reduced that risk (0.08 [0.01-0.68, P = .021).APOs remain a problem in Thai pregnant SLE patients. Renal involvement and SLE flares were associated with the risk of APOs.

Preeclampsia Risk Prediction Model for Chinese Pregnant Patients With Systemic Lupus Erythematosus

OBJECTIVE

To screen for a high risk of preeclampsia in women with systemic lupus erythematosus (SLE).

METHODS

A total of 513 antenatal care records of pregnant patients with SLE were obtained, and the data were randomly assigned to either a development set (n = 342) or a validation set (n = 171). Preeclampsia predictors were identified with stepwise regression, and a coefficient B of each variable was used to establish a prediction model and risk scoring system. Goodness-of-fit was assessed by the Hosmer-Lemeshow and Omnibus tests, and the area under the receiver operating characteristic curve (area under the curve) was used to assess discrimination. Validation was performed using the validation set.

RESULTS

The preeclampsia incidence was 14.4% in the pregnant patients with SLE. A mean arterial pressure (MAP) ≥96.5 mm Hg (odds ratio [OR] 213.15 [95% confidence interval (95% CI) 24.39-999.99]), prepregnancy hypertension (OR 18.19 [95% CI 2.67-125.01]), a hematologic disorder (OR 4.13 [95% CI 1.03-16.67]), positive IgM anticardiolipin antibodies (aCLs) (OR 19.85 [95% CI 1.11-333.33]), serum albumin <31.5 grams/liter (OR 9.88 [95% CI 2.07-47.62]), serum uric acid ≥303 μmoles/liter (OR 5.58 [95% CI 1.40-22.22]), and 24-hour urinary protein ≥0.286 grams (OR 14.39 [95% CI 2.43-83.33]) were selected for the preeclampsia prediction model. The area under the curve was 0.975. Preeclampsia prediction model scores >4 indicated a high risk of preeclampsia. For the validation set, the preeclampsia prediction accuracy was 93.6% (sensitivity 88.5%, specificity 94.5%).

CONCLUSION

A model for predicting the risk of preeclampsia in pregnant patients with SLE was established on the basis of MAP, prepregnancy hypertension, hematologic disorders, IgM aCLs, albumin, uric acid, and 24-hour urinary protein. The model had good predictive efficiency and can help clinicians improve pregnancy outcomes in high-risk women with early interventions.

Pregnancy and Systemic Lupus Erythematosus in Spain: Has Anything Changed in the 21st Century?

OBJECTIVE

To analyse a cohort of pregnant patients with systemic lupus erythematosus and compare the outcomes of both the disease and pregnancy with the results of previous studies conducted in the same geographical area.

PATIENTS AND METHODS

Retrospective cohort study of 37 women with systemic lupus erythematosus (64 pregnancies) followed in a multidisciplinary unit. Comparative study with similar Spanish studies identified after literature search.

RESULTS

Our cohort was characterized by an older age and by the presence of non-Caucasian patients. Although we found no clinical differences, from the serological point of view our cohort presented a higher frequency of antiphospholipid antibodies. Patients included in this study were treated more frequently with antimalarials and low-dose aspirin. Systemic lupus erythematosus flare frequency was very similar between the different studies, and we did not identify clear predictors for them. Although the rate of live births was similar among studies, the obstetric outcome of our series was better with a very low rate of preeclampsia, preterm birth and low birth weight newborn. The only predictor of adverse obstetric event was age.

CONCLUSIONS

Although changes in the therapeutic attitude and planning of pregnancy in recent years have not had a direct impact on the rate of systemic lupus erythematosus flares during pregnancy, they have meant an improvement in the obstetric results. The introduction of new variables independent of the disease such as age at conception, socio-cultural origin, or the availability of multidisciplinary units should be considered in the results of future studies.

Clinical features of new-onset systemic lupus erythematosus during pregnancy in Central China: a retrospective study of 68 pregnancies

The aim of this study is to explore the clinical features and pregnancy outcomes of Chinese patients with new-onset systemic lupus erythematosus (SLE) during pregnancy or puerperium. We retrospectively evaluated the data of all pregnant women with SLE managed at the First Affiliated Hospital of Zhengzhou University between April 2013 and March 2017. Clinical characteristics, laboratory features, medication use, and pregnancy outcomes were compared between pregnant women with new-onset SLE and pregnant women with pre-existing SLE. Risk factors for adverse pregnancy outcomes were determined using binary regression analyses. Overall, 223 pregnancies in 216 patients were included; 148 (69.6%) patients had a history of SLE, and 68 (30.4%) were diagnosed with SLE during pregnancy or puerperium. Most cases of new-onset SLE (72.1%) occurred during the first and second trimesters. Thrombocytopaenia (especially severe thrombocytopaenia) (76.5% vs 54.2%, P = 0.008; 39.7% vs 15.5%, P = 0.001) and anaemia (especially moderate anaemia) (73.5% vs 56.9%, P = 0.007; 52.9% vs 35.2%, P = 0.035) were more common in women with new-onset SLE than in women with pre-existing SLE and active disease during pregnancy. Additionally, patients with new-onset SLE experienced higher rates of moderate-to-severe disease activity than patients with pre-existing SLE (P < 0.01); disease activity occurred mostly during the first and second trimesters (75.4%). Compared with pre-existing SLE patients, disease activity in new-onset SLE patients occurred mostly in the first trimester (33.3% vs 15.3%, P = 0.043) and less in the third trimester (21.1% vs 47.2%, P < 0.001). Pregnancy loss was significantly higher in patients with new-onset SLE than in patients with pre-existing SLE (62.4% vs 27.1%, P < 0.001), with most cases occurring during the first and second trimesters (95.3%). However, there were no significant differences in neonatal outcomes between new-onset and pre-existing SLE patients with active disease. Within the new-onset SLE group, active disease was an independent risk factor for pregnancy loss (odds ratio [OR] = 16.185, confidence interval [CI] = 1.895-138.232, P = 0.011), whereas disease onset at late gestation was a protective factor against pregnancy loss (OR = 0.589, CI = 0.435-0.796, P = 0.013). Patients with new-onset SLE suffered greater haematological involvement (mainly thrombocytopaenia and anaemia) and higher rates of moderate-to-severe disease activity and pregnancy loss than patients with pre-existing SLE. Controlling disease activity and extending gestational age may improve pregnancy outcomes in women with new-onset SLE. Key Points • The clinical features of new-onset SLE during pregnancy and its impact on pregnancy outcomes have rarely been reported, especially in Chinese patients. • New-onset SLE during pregnancy in Chinese women occurred primarily during the first and second trimesters and was characterised by haematological disorders, including thrombocytopaenia and anaemia. • Women with new-onset SLE during pregnancy had significantly higher disease activity scores and pregnancy loss rates than women with pre-existing SLE, especially during the first and second trimesters; controlling disease activity and prolonging gestational age may improve pregnancy outcomes in this setting.

Systemic lupus erythematosus: an expert insight into emerging therapy agents in preclinical and early clinical development

INTRODUCTION

Systemic lupus erythematosus (SLE) is a chronic disease that is potentially fatal. There is no cure for SLE and the medications used are associated with toxic side effects. In the era of revolutionary emerging novel biologic agents, the design and investigation of targeted therapy for these patients is necessary. Novel therapies under investigation in phase II-III clinical trials showed promising results. Therapies can target various pathways involved in SLE including cytokines, signal transduction inhibitors, B-cell depletion and interference with co-stimulation. Of interest is the proof of concept of sequential therapy.

AREAS COVERED

We performed an extensive literature search via PubMed, Medline, Elsevier Science and Springer Link databases between the years 2014-2020 using the following terms: SLE, novel treatments. We have reviewed 232 articles and selected those articles that (i) focus on phase II-III emerging therapies and (ii) offer new findings from existing therapies, which reveal breakthrough concepts in SLE treatment.

EXPERT OPINION

It is still difficult to crack the puzzle of a successful SLE treatment approach. New strategies with potential may encompass the targeting of more than one protein. Another way forward is to identify each SLE patient and personalize therapy by clinical manifestations, disease activity, serology and activated protein.

Adverse Pregnancy Outcomes after Multi-Professional Follow-Up of Women with Systemic Lupus Erythematosus: An Observational Study from a Single Centre in Sweden

While the management of pregnant patients with systemic lupus erythematosus (SLE) has improved over the last decades, the risk of maternal, foetal, and neonatal complications is still substantial. We evaluated the occurrence of adverse pregnancy outcomes (APO) occurring in 2002–2018 among patients with SLE from the catchment area of the Department of Rheumatology in Lund, Sweden. Longitudinal clinical and laboratory data were collected and analysed. Results were stratified according to the sequence of conception. We investigated a total of 59 pregnancies in 28 patients. Prior lupus nephritis was the clinical feature that, in a multivariable regression analysis, displayed the strongest association with APO overall (OR 6.0, p = 0.02). SLE combined with antiphospholipid syndrome (APS) was associated with the risk of miscarriage (OR 3.3, p = 0.04). The positivity of multiple antiphospholipid antibodies (aPL) was associated with APO overall (OR 3.3, p = 0.05). IgG anti-cardiolipin during pregnancy resulted in a higher risk of preterm delivery (OR 6.8, p = 0.03). Hypocomplementaemia was associated with several APO, but only in the first pregnancies. We conclude that, despite the close follow-up provided, a majority of pregnancies resulted in ≥1 APO, but a few of them were severe. Our study confirms the importance of previous lupus nephritis as a main risk factor for APO in patients with SLE.

Risk of adverse obstetric outcomes in Japanese women with systemic lupus erythematosus: The Japan Environment and Children's Study

Systemic lupus erythematosus, simply known as lupus, is associated with adverse obstetric outcomes. This study evaluated the incidence of preterm births (before 37 and 34 weeks), low birthweight infants (<2500 g and <1500 g), small-for-gestational age infants, preterm premature rupture of membranes, and gestational hypertension in mothers with lupus and compared them with those of the Japanese general population. Data from participants in the Japan Environment and Children's Study who gave birth between 2011 and 2014 were collected. Only participants with singleton pregnancies were included. Adjusted odds ratios for the variables were calculated using a logistic regression model, with a general population as the reference. In total, 88,017 participants were included in the analysis, and 63 of them had lupus. The adjusted odds ratios of preterm births before 37 and 34 weeks, low birthweight infants <2500 g and <1500 g, small-for-gestational age infants, and preterm premature rupture of membranes in the systemic lupus erythematosus group were 8.1 (95% CI, 4.7-14.1), 5.2 (1.6-16.5), 6.5 (3.9-10.8), 5.4 (1.3-22.4), 2.9 (1.4-5.9), and 12.1 (5.7-25.5), respectively. The adjusted odds ratio of gestational hypertension was 1.4 (0.4-4.5). This study revealed increased risk of preterm births, low birthweight infants, small-for-gestational age infants, and preterm premature rupture of membranes in patients with lupus when compared with those in the general population.

Perceptions of women with systemic lupus erythematosus undergoing high-risk prenatal care: A qualitative study

BACKGROUND

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that often leads to situations of harm to the mother-fetus binomial. Given the potential for complications and morbidities in these pregnant women, it is essential that a multidisciplinary team be involved in pregnancy planning, as well as monitoring the course of the pregnancy and the postpartum period. Owing to the imminent risks of disease worsening along with consequent disabilities, these women may experience psychological and psychosocial impacts conflicting with the psychological demands of pregnancy.

OBJECTIVE

To understand the meanings attributed to pregnancy by women with SLE.

DESIGN

A qualitative design with face-to-face interview following a semi-structured script of open-ended questions.

SETTING

A specialized outpatient clinic where during prenatal care, women with stable disease undergo scheduled appointments.

PARTICIPANTS

The sample was intentionally composed of women visiting a specialized outpatient clinic from July 2017 to July 2018. The participants (N = 26) were interviewed in depth, with no refusal. Thematic analysis according to the 7 steps of qualitative analysis was conducted using NVivo 11.

FINDINGS

Four categories were identified: (1) unplanned pregnancy and nonuse of contraception, (2) feeling healthy despite a doctor's warning of the disease worsening because of pregnancy, (3) joy coupled with fear of the future and pregnancy, and (4) self-perception and straight perception.

CONCLUSIONS

The experiences of pregnant women with SLE are permeated by ambiguous feelings. These women feel healthy because they can bear a child despite the chronic disease diagnosis and, at the same time, experience fear and insecurity owing to the imminent possibility of disease-related disabilities and limitations. They especially wish to experience motherhood, and they strive for safety and support.

IMPLICATIONS FOR PRACTICE

Health teams must be structured to welcome and advise these women in planning relationships and pregnancy, as well as choosing the best contraceptive methods and making optimal reproductive decisions. The development of strategies to deal with changes in the perinatal period may be helpful, as these women are willing to take care of themselves.

Systemic lupus erythematosus in pregnancy: high risk, high reward

PURPOSE OF REVIEW

The aim of this study was to describe risks of systemic lupus erythematosus (SLE) in pregnancy and the importance of preconception counselling, medication optimization and close surveillance.

RECENT FINDINGS

Advances in care for pregnant patients with SLE have led to improved obstetric outcomes, but maternal and foetal risks continue to be elevated. Conception during periods of disease quiescence and continuation of most medications decrease adverse pregnancy outcomes. Hydroxychloroquine (HCQ) appears protective against flares in pregnancy, neonatal congenital heart block and preterm birth.

SUMMARY

SLE in pregnancy confers increased maternal and foetal risks, including disease flares, preeclampsia, preterm birth, foetal growth restriction, neonatal lupus erythematosus (NLE) and congenital heart block. Disease control on an effective medication regimen mitigates many of these risks, but pregnancy in women with SLE remains a high-risk condition requiring multidisciplinary care and an individualized approach to each patient.

Neuromyelitis optica spectrum disorders and pregnancy: therapeutic considerations

Neuromyelitis optica spectrum disorders (NMOSD) are a type of neurological autoimmune disease characterized by attacks of CNS inflammation that are often severe and predominantly affect the spinal cord and optic nerve. The majority of individuals with NMOSD are women, many of whom are of childbearing age. Although NMOSD are rare, several small retrospective studies and case reports have indicated that pregnancy can worsen disease activity and might contribute to disease onset. NMOSD disease activity seems to negatively affect pregnancy outcomes. Moreover, some of the current NMOSD treatments are known to pose risks to the developing fetus and only limited safety data are available for others. Here, we review published studies regarding the relationship between pregnancy outcomes and NMOSD disease activity. We also assess the risks associated with using disease-modifying therapies for NMOSD during the course of pregnancy and breastfeeding. On the basis of the available evidence, we offer recommendations regarding the use of these therapies in the course of pregnancy planning in individuals with NMOSD.

Preterm birth phenotypes in women with autoimmune rheumatic diseases: a population-based cohort study

OBJECTIVE

To investigate preterm birth (PTB) phenotypes in women with different autoimmune rheumatic diseases in a large population-based cohort.

DESIGN

Retrospective cohort study.

SETTING

California, USA.

POPULATION

All live singleton births in California between 2007 and 2011 were analysed. Patients with autoimmune disease at delivery were identified by International Classification of Diseases, Ninth Revision , Clinical Modification (ICD-9-CM), codes for systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA), polymyositis/dermatomyositis (DM/PM), and juvenile idiopathic arthritis (JIA).

METHODS

Maternally linked hospital and birth certificate records of 2 481 516 deliveries were assessed (SLE n = 2272, RA n = 1501, SSc n = 88, JIA n = 187, DM/PM n = 38). Multivariable Poisson regression models estimated the risk ratios (RRs) for different PTB phenotypes (relative to term deliveries) for each autoimmune disease compared with the general obstetric population, adjusting for maternal age, race/ethnicity, body mass index, smoking, education, payer, parity, and prenatal care.

MAIN OUTCOME MEASURES

Preterm birth (PTB) was assessed overall (20-36 weeks of gestation) and by subphenotype: preterm prelabour rupture of membranes (PPROM), spontaneous birth, or medically indicated PTB. The risk of PTB overall and for each phenotype was partitioned by gestational age: early (20-31 weeks of gestation) and late (32-36 weeks of gestation).

RESULTS

Risks for PTB were elevated for each autoimmune disease evaluated: SLE (RR 3.27, 95% CI 3.01-3.56), RA (RR 2.04, 95% CI 1.79-2.33), SSc (RR 3.74, 95% CI 2.51-5.58), JIA (RR 2.23, 95% CI 1.54-3.23), and DM/PM (RR 5.26, 95% CI 3.12-8.89). These elevated risks were observed for the majority of PTB phenotypes as well.

CONCLUSIONS

Women with systemic autoimmune diseases appear to have an elevated risk of various PTB phenotypes. Therefore, preconception counselling and close monitoring during pregnancy is crucial.

TWEETABLE ABSTRACT

This study found that women with systemic autoimmune diseases have an elevated risk of preterm birth phenotypes.

Systemic lupus erythematosus and pregnancy: the challenge of improving antenatal care and outcomes

OBJECTIVES

The objective of this article is to describe maternal and perinatal outcomes in women with systemic lupus erythematosus (SLE) followed in a high-risk prenatal outpatient clinic at a referral center.

METHODS

This observational study included pregnant women with SLE who underwent prenatal follow-up and childbirth at the Women's Hospital, University of Campinas, from January 2012 to January 2018. All women were followed according to the institution's protocol for pregnant women with SLE. They were subdivided into two groups according to the presence of disease activity during the preconception and gestation periods, and evaluated according to the Systemic Lupus Erythematosus Disease Activity Index and Systemic Lupus Erythematosus Pregnancy Disease Activity Index scales. Data were retrieved from patients' medical records. Chi-square, Fisher exact and Mann-Whitney tests and multivariable analyses were performed. Statistical significance level was 5% (p < .05).

RESULTS

A total of 125 cases were initially included; those who were lost to follow-up or gave birth at another hospital were further excluded, with 102 pregnancies (of 95 women) remaining. The mean age of the women was 27.7 years (SD 5.44), and 48% were in their first gestation. The average duration of disease was 6.79 years (SD 5.38), with 92.1% receiving SLE-specific therapy. SLE flare occurred in 8.9% during the preconception period and 23.5% during gestation. Preterm premature rupture of membranes (16.6%), preeclampsia or eclampsia (15.6%) and preterm labor (12.7%) were the most frequent complications. The mean gestational age at birth was 34.4 weeks (SD 5.9); the preterm birth rate was 46.8%, the low birth weight rate was 35.1%, and intensive neonatal care admission was 40.4%. Four fetal deaths and one maternal death occurred, all of them in the group with SLE flares. Multivariable logistic regression analysis showed that preconception lupus activity had a six-fold increased rate of gestational loss (odds ratio (OR): 6.14 (95% confidence interval (CI) 1.26-29.99)), and lupus activity during pregnancy had a five-fold increased rate of prematurity at less than 34 weeks (OR: 5.02 (95% CI: 1.90-13.30)).

CONCLUSIONS

Despite the low percentages of women with pregestational and pregnancy-active disease, we found high incidences of maternal and perinatal complications. Preconception SLE activity increased gestational loss, and SLE activity during pregnancy increased prematurity. Effective immunosuppressive therapy was able to decrease clinical and laboratory activity of SLE; however, unfavorable perinatal outcomes still occurred, even when lupus activity was under control. Pregnancy in women with SLE is always a challenge.

Maternal and fetal outcomes in pregnancies with long-term corticosteroid use

PURPOSE

Long-term corticosteroids are administered in pregnant patients with an array of autoimmune and inflammatory disorders. Our objective is to determine whether long-term corticosteroid use is associated with increased maternal and neonatal adverse outcomes.

MATERIALS AND METHODS

We performed a retrospective cohort study using the Healthcare Cost and Utilization Project-national Inpatient Sample from the USA. All pregnant patients on long-term corticosteroids were identified using International Classification of Disease-9 coding from 2003 to 2015. The effect of long-term corticosteroid use on maternal and neonatal outcomes was evaluated using multivariate logistic regression.

RESULTS

Out of the 10,491,798 births included in our study, 3999 were among women with long-term use of steroids, for an overall prevalence of 38 per 100,000 births. There was a steady increase in chronic steroid use from 2 to 81 per 100,000 births over the 13-year study period (p < .0001). Women on long-term steroids were more likely to have pregnancies complicated by preeclampsia, 1.72 (1.30-2.29) and were at greater risk of preterm premature rupture of membranes, 1.63 (1.01-2.44), pyelonephritis, 4.81 (1.18-19.61), and venous thromboembolisms, 2.50 (1.32-4.73). Neonates born from mothers on long-term steroids were more likely to suffer from prematurity, 1.51 (1.13-2.05), and lower weight for gestational age, 2.10 (1.34-3.30).

CONCLUSION

Long-term corticosteroids use in pregnancy is associated with maternal and fetal adverse outcomes. These patients would benefit from close follow-up throughout their pregnancy to minimize complications.

Safety of fertility treatments in women with systemic autoimmune diseases (SADs)

Introduction: Systemic Autoimmune Diseases (SADs) include systemic lupus erythematosus, antiphospholipid antibody syndrome, rheumatoid arthritis, systemic sclerosis, Sjogren's syndrome, mixed connective tissue disease, idiopathic inflammatory myopathies and vasculitis. SADs often occur in women of childbearing age and can affect fertility. Both infertility treatments and fertility preservation techniques are thus often indicated. Areas covered: The literature regarding the safety of fertility-related drugs for both fertility preservation and infertility treatment in patients affected by SADs was reviewed. Based on current knowledge, all the options for fertility preservation should be contemplated in patients with SADs who are at risk for fertility loss, including GnRH analogue administration, oocyte/embryo vitrification and ovarian tissue cryopreservation. Similarly, if pregnancy is not contraindicated in a patient with a SAD, neither should be any fertility treatment. Expert opinion: Women with SADs should postpone conception until a stable disease has been achieved for at least 6 months. When infertility treatments are needed, women with antiphospholipid antibodies should receive concomitant anticoagulation. If in vitro fertilization/intra-cytoplasmic sperm injection and embryo transfer is required, ovarian hyperstimulation and the inherent risk of thrombosis should be eliminated by GnRH-agonist trigger and cycle segmentation. Counselling about adherence to anti-rheumatic therapy to prevent disease exacerbations is also critical.

Clinical outcomes and predictors of maternal and fetal complications in pregnancies of patients with systemic lupus erythematosus

INTRODUCTION

Systemic Lupus Erythematosus (SLE) mostly affects women during their childbearing years. Fertility is preserved in SLE patients, but pregnancy is often characterized by a high number of maternal and fetal complications. Adverse pregnancy outcomes (APO) have been widely studied over the last decades and several investigators have focused on the potential clinical and serological predictors of maternal and fetal complications. Areas covered: In this review, we analyzed maternal and fetal complications in SLE patients and predictors of APO. Active disease in the 6 months before conception, lupus nephritis, anti-phospholipid (aPL), anti-SSA/Ro and/or anti-SSB/La antibodies have been identified as the most consistent predictors of maternal and fetal complications to date. However, molecular mechanisms and underlying immunological pathways involved in APO still remain elusive. Expert opinion: Difficulties in assessing prevalence and predictors of APO in SLE patients are due to lack of uniformity in the definitions and methods used in the different studies. In addition, some maternal and fetal complications are difficult to diagnose and to differentiate from each other. Preconception counseling is paramount to prevent APO, and it should consider four main factors: disease activity/lupus nephritis, safety of drugs, aPL, anti-SSA/Ro, and/or anti-SSB/La antibodies.
