Maternal and fetal outcomes in pregnant women with rheumatoid arthritis: a systematic review and meta-analysis

Management of pregnant with rheumatoid arthritis: Preconception care, pregnancy and lactation strategies, and maternal-fetal outcomes

Rheumatoid arthritis (RA) is a chronic inflammatory disorder that can affect women of reproductive age. In recent decades, significant advances have been made in the development of new medications, including biologic disease-modifying anti-rheumatic drugs (DMARDs) and Janus kinase (JAK) inhibitors. Women with RA are prone to infertility, with 42% experiencing a time to pregnancy exceeding 12 months. High disease activity, as well as the use of high-dose glucocorticoids and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), are associated with infertility and adverse pregnancy outcomes. Additionally, some medications, such as methotrexate, are linked to teratogenicity, highlighting the importance of providing preconception care in everyday practice. Recent advancements in reproductive care have improved our ability to manage RA during pregnancy, leading to better pregnancy outcomes. In this review, we summarize key aspects of fertility care, pregnancy and lactation management, including medication strategies, neonatal vaccination, and long-term outcomes for offspring born to mothers with RA.

Trajectories of biologic drug use before, during and after pregnancy: an Italian cohort study from the VALORE project

BACKGROUND

Monitoring biologic drug therapy during pregnancy in women with immune-mediated inflammatory diseases (IMIDs) is crucial to ensure treatments align with evidence-based practices.

RESEARCH DESIGN AND METHODS

A retrospective cohort study based on healthcare claims data from eight Italian regions was conducted, analyzing deliveries between 2009 and 2021. The study included women receiving biologic drugs within nine months before their last menstruation. Exposures to biologics, conventional disease-modifying anti-rheumatic drugs (DMARDs) and symptom-relieving medications were assessed in the trimesters (T) before, during and after pregnancy. Factors influencing biologic treatment persistence during pregnancy were analyzed.

RESULTS

A cohort of 1,763 deliveries was considered. Biologic drugs were prescribed for rheumatic (33.6%), dermatological (32.6%), and gastrointestinal diseases (28.4%). Biologic use declined during pregnancy (TI = 37.3%; TII = 17.6%; TIII = 11.3%), increasing again postpartum. During pregnancy, there was increased use of symptom-relieving medications for rheumatic diseases and DMARDs for gastrointestinal diseases. Factors associated with continued biologic treatment included being older than 35 years and the region of delivery.

CONCLUSIONS

This study found a decrease in biologics drug use during pregnancy and highlights the necessity for personalized therapeutic approaches. Geographic variations in biologic drug use emphasize the need for educational initiatives about the risk-benefit profiles of these therapies during pregnancy.

Pregnancy Outcomes from a Multidisciplinary Obstetric-Medicine/Rheumatology Clinic in the United States: A Five-Year Retrospective Analysis

OBJECTIVE

At Women & Infants Hospital in Providence, Rhode Island, the Specialty Care in Pregnancy clinic combines obstetric-medicine internists with rheumatologists to care for pregnant patients with rheumatologic conditions. These clinics are scarce, with only three known similar clinics in the United States. This study aims to characterize the population cared for in this clinic, identify interventions, and analyze pregnancy outcomes for the birthing parents and newborns.

METHODS

A five-year retrospective chart review was performed from January 1st, 2016, through December 31st, 2021.

RESULTS

Of 81 patients, 62% had a clinically diagnosed rheumatic disorder. Of 87 patient visits, which included preconception, prenatal, and postpartum encounters, 54% of patients were taking conventional synthetic disease modifying antirheumatic drugs, and 17% were taking biologic disease modifying antirheumatic drugs. New medications were started in 52% of patients. A total of 52% of pregnancies resulted in live births, with 2% resulting in miscarriages. Prematurity occurred in 19% of newborns, and 9% had intrauterine growth restriction.

CONCLUSION

Our study illustrates the benefits of multidisciplinary care in patients with rheumatologic disorders during their prenatal and perinatal periods. The expertise from both the obstetric-medicine internists and rheumatologists was critical in making complex decisions that weighed the benefits of therapy against potential risks for the fetus. Our multidisciplinary approach resulted in doubling of the number of patients initiating disease modifying therapy and increased prophylaxis with hydroxychloroquine and/or aspirin therapy, as recommended by current guidelines. Additional multidisciplinary clinics of this type would help coordinate care among physicians who frequently treat these high-risk, unique patients and open the door for more research of this understudied population.

Updating on pregnancy in rheumatoid arthritis

INTRODUCTION

Rheumatoid arthritis (RA), the most prevalent autoimmune disease in reproductive years, exhibits a higher incidence in females, suggesting involvement of estrogens, genetics and environmental factors in disease onset. Literature shows smaller families in RA patients, driving increased interest in Assisted Reproductive Techniques.

AREAS COVERED

This review elucidates how immunotolerance mechanisms contribute to favorable pregnancy outcomes in RA, emphasizing the need for a careful pregnancy planning to mitigate fetal complications and postnatal flares, which surpass those in the general population. A thorough medication evaluation, orchestrated by a multidisciplinary team, is imperative during pregnancy, weighing potential teratogenic effects against safer alternatives to balance medication safety with disease control. A systematic literature search on PubMed and MEDLINE, using specific terms, covered relevant academic journals up to the latest date.

EXPERT OPINION

This narrative review comprehensively addresses pregnancy-related considerations in RA patients, prioritizing meticulous disease management with pregnancy and breastfeeding-compatible drugs in line with the latest recommendations and registry data. The focus remains on evaluating glucocorticoids, conventional, and biological disease-modifying drugs for compatibility during pregnancy and breastfeeding. Additionally, the evolving landscape of targeted synthetic drugs during pregnancy is explored, providing insights into the latest developments in rheumatological care.

The time of equipoise on the use of biological DMARDs in for inflammatory arthritis during pregnancy is finally over: a reappraisal of evidence to optimise pregnancy management

Active inflammatory arthritis in pregnancy is associated with an increased risk of adverse pregnancy outcomes. Treatment of active inflammation and maintenance of low disease activity with medication reduces these risks. Therapeutic decisions on disease-modifying antirheumatic drugs (DMARDs) in pregnancy are complicated by safety concerns, which have led to inappropriate withdrawal of treatment and consequential harm to mother and fetus. Studies of inflammatory arthritis in pregnancy have consistently shown minimal safety concerns with the use of biological DMARDs and an increased risk of disease flare with discontinuation of biological DMARDs. It is our opinion that during pregnancy, the benefits of disease control with biological DMARDs, when required in addition to conventional synthetic DMARDs, outweigh the risks. In this Series paper, we review the reasons for reconsideration of equipoise and propose an agenda for future research to optimise the use of biological DMARDs in inflammatory arthritis during pregnancy.

Rheumatoid arthritis and adverse pregnancy outcomes: a bidirectional two-sample mendelian randomization study

BACKGROUND

There is growing evidence of bidirectional associations between rheumatoid arthritis and adverse pregnancy outcomes (APOs) in observational studies, but little is known about the causal direction of these associations. Therefore, we explored the potential causal relationships between rheumatoid arthritis and APOs using a bidirectional two-sample Mendelian randomization (MR) in European and Asian populations.

METHODS

We conducted a bidirectional two-sample Mendelian randomization analysis using available summary statistics from released genome-wide association studies. Summary statistics for instrument-outcome associations were retrieved from two separate databases for rheumatoid arthritis and adverse pregnancy outcomes, respectively. The inverse-variance weighted method was used as the primary MR analysis, and cML-MA-BIC was used as the supplementary analysis. MR-Egger, MR pleiotropy residual sum and outlier (MR-PRESSO), and Cochran Q statistic method were implemented as sensitivity analyses approach to ensure the robustness of the results.

RESULTS

Our study showed that a higher risk of rheumatoid arthritis in the European population was associated with gestational hypertension (OR: 1.04, 95%CI: 1.02-1.06), pre-eclampsia (OR: 1.06, 95%CI: 1.01-1.11), fetal growth restriction (OR: 1.08, 95%CI: 1.04-1.12), preterm delivery (OR:1.04, 95%CI: 1.01-1.07). Furthermore, we found no evidence that APOs had causal effects on rheumatoid arthritis in the reverse MR analysis. No association between rheumatoid arthritis and APOs was found in East Asian population. There was no heterogeneity or horizontal pleiotropy.

CONCLUSIONS

This MR analysis provides the positive causal association from rheumatoid arthritis to gestational hypertension, pre-eclampsia, fetal growth restriction and preterm delivery genetically. It highlights the importance of more intensive prenatal care and early intervention among pregnant women with rheumatoid arthritis to prevent potential adverse obstetric outcomes.

Machine learning techniques for prediction in pregnancy complicated by autoimmune rheumatic diseases: Applications and challenges

Autoimmune rheumatic diseases are chronic conditions affecting multiple systems and often occurring in young women of childbearing age. The diseases and the physiological characteristics of pregnancy significantly impact maternal-fetal health and pregnancy outcomes. Currently, the integration of big data with healthcare has led to the increasing popularity of using machine learning (ML) to mine clinical data for studying pregnancy complications. In this review, we introduce the basics of ML and the recent advances and trends of ML in different prediction applications for common pregnancy complications by autoimmune rheumatic diseases. Finally, the challenges and future for enhancing the accuracy, reliability, and clinical applicability of ML in prediction have been discussed. This review will provide insights into the utilization of ML in identifying and assisting clinical decision-making for pregnancy complications, while also establishing a foundation for exploring comprehensive management strategies for pregnancy and enhancing maternal and child health.

Impact of Sjögren's syndrome on maternal and fetal outcomes following pregnancy: a systematic review and meta-analysis of studies published between years 2007-2022

OBJECTIVE

To show the impact of Sjögren's syndrome (SS) on maternal and fetal outcomes following pregnancy.

METHODS

We performed a literature search based on PubMed, Web of science, Wan fang, China National Knowledge Infrastructure and ProQuest databases from 1 January 2007 to 6 November 2022. Grading of Recommendations, Assessment, Development, and Evaluations approach was used to assess the certainty of the evidence. Systematic reviews and meta-analyses were performed using RevMan 5.3 software. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method of DerSimonian and Laird. Trial sequential analyses were performed by TSA 0.9.

RESULTS

Nine studies with 2341 patients and 2472 pregnancies with SS were included in our analysis. This current analysis showed pregnancy hypertension and preeclampsia/eclampsia to be significantly higher in pregnant women with SS compared to pregnant women without SS (OR: 1.65, 95% CI: 1.04-2.63; P = 0.03), (OR: 2.06, 95% CI: 1.16-3.65; P = 0.01) respectively. Cesarean section, thromboembolic disease, premature rupture of membranes, and spontaneous abortion were also significantly higher in the SS women with OR: 2.07, 95% CI: 1.48-2.88; P < 0.0001, OR: 9.45, 95% CI: 1.99-44.87; P = 0.005, OR: 1.36, 95% CI: 1.13-1.64; P = 0.001, OR: 9.30, 95% CI: 4.13-20.93; P < 0.00001, respectively. Significantly higher premature births were observed with infants who were born from SS mothers (OR: 2.19, 95% CI: 1.54-3.12; P < 0.0001). Infants defined as 'small for gestational age/intrauterine growth restriction' and 'weighing < 2500 g' were also significantly higher in patients suffering from SS (OR: 2.26, 95% CI: 1.38-3.70; P = 0.001), (OR: 3.84, 95% CI: 1.39-10.61; P = 0.009) respectively. In addition, live birth significantly favored infants who were born from mothers without SS (OR: 21.53, 95% CI: 8.36-55.44; P < 0.00001). Subgroup analysis by sample size revealed that pregnancy hypertension risk has significantly increased in small cohort (OR: 2.74, 95%CI: 1.45-5.18), and a slight increase was found in population-based studies (OR: 1.14, 95%CI: 0.91-1.43). In both small cohorts and population-based researches, cesarean section was significantly higher in SS (OR: 2.13, 95% CI: 1.29, 3.52; OR: 1.85, 95% CI: 1.29-2.64, respectively). The number of infants with intrauterine growth restriction did not grow in the population-based researches (OR: 2.07, 95%CI: 0.92-4.66) although there has been an increase in small reports (OR: 2.53, 95%CI: 1.16-5.51). Subgroup analysis was conducted on the basis of study location (not Asian vs. Asian countries) indicated that cesarean section was significantly higher in SS in both countries (OR: 1.69, 95% CI: 1.31-2.18; OR: 3.37, 95% CI: 2.39-4.77, respectively).

CONCLUSION

This meta-analysis has shown SS to have a high impact on maternal and fetal outcomes following pregnancy.

Maternal-fetal outcomes in patients with immune-mediated inflammatory diseases, with consideration of comorbidities: a retrospective cohort study in a large U.S. healthcare system

Background

Immune-mediated inflammatory diseases (IMIDs) are likely to complicate maternal health. However, literature on patients with IMIDs undergoing pregnancy is scarce and often overlooks the presence of comorbidities. We aimed to evaluate the impact of IMIDs on adverse pregnancy outcomes after assessing and addressing any discrepancies in the distribution of covariates associated with adverse pregnancy outcomes between patients with and without IMIDs.

Methods

We conducted a retrospective cohort study using data from an integrated U.S. community healthcare system that provides care across Alaska, California, Montana, Oregon, New Mexico, Texas, and Washington. We used a database containing all structured data from electronic health record (EHRs) and analyzed the cohort of pregnant people who had live births from January 1, 2013, through December 31, 2022. We investigated 12 selected IMIDs: psoriasis, inflammatory bowel disease, rheumatoid arthritis, spondyloarthritis, multiple sclerosis, systemic lupus erythematosus, psoriatic arthritis, antiphospholipid syndrome, Sjögren's syndrome, vasculitides, sarcoidosis, and systemic sclerosis. We characterized patients with IMIDs prior to pregnancy (IMIDs group) based on pregnancy/maternal characteristics, comorbidities, and pre-pregnancy/prenatal immunomodulatory medications (IMMs) prescription patterns. We 1:1 propensity score matched the IMIDs cohort with people who had no IMID diagnoses prior to pregnancy (non-IMIDs cohort). Outcome measures were preterm birth (PTB), low birth weight (LBW), small for gestational age (SGA), and caesarean section.

Findings

Our analytic cohort had 365,075 people, of which 5784 were in the IMIDs group and 359,291 were in the non-IMIDs group. The prevalence rate of pregnancy of at least 20 weeks duration in people with a previous IMID diagnosis has doubled in the past ten years. 17% of the IMIDs group had at least one prenatal IMM prescription. Depending on the type of IMM, 48%-70% of the patients taking IMMs before pregnancy continued them throughout pregnancy. Overall, patients with one or more of these 12 IMIDs had increased risk of PTB (Relative risk (RR) = 1.1 [1.0, 1.3]; p = 0.08), LBW (RR = 1.2 [1.0, 1.4]; p = 0.02), SGA (RR = 1.1 [1.0, 1.2]; p = 0.03), and caesarean section (RR = 1.1 [1.1, 1.2], p < 0.0001) compared to a matched cohort of people without IMIDs. When adjusted for comorbidities, patients with rheumatoid arthritis (PTB RR = 1.2, p = 0.5; LBW RR = 1.1, p = 0.6) and/or inflammatory bowel disease (PTB RR = 1.2, p = 0.3; LBW RR = 1.0, p = 0.8) did not have significantly increased risk for PTB and LBW.

Interpretation

For patients who have been pregnant for 20 weeks or greater, the association between IMIDs and adverse pregnancy outcomes depends on both the nature of the IMID and the presence of comorbidities. Because this study was limited to pregnancies resulting in live births, results must be interpreted together with other studies on early pregnancy loss and stillbirth in patient with IMIDs.

Pregnancy outcomes in women with rheumatoid arthritis: an 11-year French nationwide study

BACKGROUND

Rheumatoid arthritis (RA) can affect women of childbearing age. The management of patients with RA during pregnancy has evolved over the past decades, especially with the availability of new therapeutic molecules.

OBJECTIVES

To describe pregnancy in women with RA, to compare pregnancy outcomes with those of women in the general population and to compare pregnancy outcomes in women with active and inactive RA.

METHODS

Using the French National Health Data System, we identified all pregnancies ending between 2010 and 2020 in patients with and without RA. Characteristics were described. Active RA was defined by conventional synthetic/biological/targeted synthetic disease-modifying antirheumatic drug initiation, systemic or intra-articular corticosteroid administration and/or RA-related hospitalisation. Pregnancy outcomes were compared computing multivariable logistic marginal regression model using generalised estimating equation (GEE).

RESULTS

We included 11 792 RA and 10 413 681 non-RA pregnancies. Among RA pregnancies, 74.5% ended in live births and 0.4% in stillbirths. RA pregnancies resulted more frequently in preterm births (adjusted OR (ORa) 1.84; 95% CI 1.69 to 2.00) and very preterm births (ORa 1.43; 95% CI 1.20 to 1.71), low birth weight (ORa 1.65; 95% CI: 1.52 to 1.90), caesarean section (ORa 1.46; 95% CI 1.38 to 1.55) and pregnancy-related hospitalisation (ORa 1.30; 95% CI 1.22 to 1.39). Disease activity decreased during pregnancy. Active RA had higher rates of prematurity (ORa 2.02; 95% CI 1.71 to 2.38), small for gestational age (ORa 1.53; 95% CI 1.28 to 1.83) and caesarean section (ORa 1.25; 95% CI 1.11 to 1.40) than non-active RA.

CONCLUSION

Pregnancies in women with RA were associated with more adverse outcomes, especially if the disease was active. These findings should encourage physicians to closely monitor RA during this crucial period.

Causal association between rheumatoid arthritis and pregnancy loss and intrauterine growth retardation: A bidirectional two-sample Mendelian randomization study

OBJECTIVE

To investigate the causal relationship between rheumatoid arthritis (RA) and pregnancy loss and intrauterine growth retardation (IUGR) using Mendelian randomization (MR).

METHODS

Genetic variants associated with RA (12,555 cases and 240,862 controls), miscarriage (1475 cases and 149,622 controls), and IUGR (3558 cases and 207,312 controls) were obtained from the FinnGen consortium, and supplementary data on RA (5201 cases and 457,732 controls) and miscarriage (7069 cases and 250,492 controls) were obtained from the Medical Research Council Integrated Epidemiology Unit (MRC-IEU). 47 Single nucleotide polymorphisms (SNPs) associated with RA were screened as instrumental variables (IV). The causal relationship between RA and pregnancy loss and IUGR were assessed by 5 MR methods, mainly inverse variance weighting (IVW). Sensitivity analyses were also performed to test the stability of the results.

RESULTS

Bidirectional MR showed that genetically predicted RA was causally associated with pregnancy loss and IUGR in forward MR analyses, and that RA significantly increased pregnancy loss [odds ratio (OR) = 1.13, 95% confidence interval (CI): 1.00-1.33, P = .03] and IUGR (OR = 1.08, 95% CI: 1.01-1.15, P = .019). In the reverse MR, there was no causal association between pregnancy loss (P = .15) and IUGR (P = .87) and RA.

CONCLUSION

This study found a significant genetic association between RA and pregnancy loss and IUGR. RA is considered to be a high-risk factor for adverse maternal outcomes. Pre-pregnancy prophylaxis and intra-pregnancy control of patients should be emphasized to reduce the incidence of adverse pregnancy outcomes such as pregnancy loss and IUGR.

Global, regional and national temporal trends in prevalence for musculoskeletal disorders in women of childbearing age, 1990-2019: an age-period-cohort analysis based on the Global Burden of Disease Study 2019

OBJECTIVES

To provide an overview and in-depth analysis of temporal trends in prevalence of musculoskeletal (MSK) disorders in women of childbearing age (WCBA) at global, regional and national levels over the last 30 years, with a special focus on their associations with age, period and birth cohort.

METHODS

Estimates and 95% uncertainty intervals (UIs) for MSK disorders prevalence in WCBA were extracted from the Global Burden of Diseases, Injuries and Risk Factors Study 2019. An age-period-cohort model was adopted to estimate the overall annual percentage change of prevalence (net drift, % per year), annual percentage change of prevalence within each age group (local drift, % per year), fitted longitudinal age-specific rates adjusted for period deviations (age effects) and period/cohort relative risks (period/cohort effects) from 1990 to 2019.

RESULTS

In 2019, the global number of MSK disorders prevalence in WCBA was 354.57 million (95% UI: 322.64 to 387.68). Fifty countries had at least one million prevalence, with India, China, the USA, Indonesia and Brazil being the highest accounting for 51.03% of global prevalence. From 1990 to 2019, a global net drift of MSK disorders prevalence in WCBA was -0.06% (95% CI: -0.07% to -0.05%) per year, ranging from -0.09% (95% CI: -0.10% to -0.07%) in low-middle sociodemographic index (SDI) region to 0.10% (95% CI: 0.08% to 0.12%) in high-middle SDI region, with 138 countries presenting increasing trends, 24 presenting decreasing trends and 42 presenting relatively flat trends. As reflected by local drift, higher SDI regions had more age groups showing rising prevalence whereas lower SDI regions had more declining prevalence. Globally, an increasing occurrence of MSK disorders prevalence in WCBA beyond adolescent and towards the adult stage has been prominent. Age effects illustrated similar patterns across different SDI regions, with risk increasing with age. High SDI region showed generally lower period risks over time, whereas others showed more unfavourable period risks. High, high-middle and middle SDI regions presented unfavourable prevalence deteriorations, whereas others presented favourable prevalence improvements in successively birth cohorts.

CONCLUSIONS

Although a favourable overall temporal trend (net drift) of MSK disorders prevalence in WCBA was observed over the last 30 years globally, there were 138 countries showing unfavourable rising trends, coupled with deteriorations in period/cohort risks in many countries, collectively raising concerns about timely realisation of the Targets of Sustainable Development Goal. Improvements in the MSK disorders-related prevention, management and treatment programmes in WCBA could decline the relative risk for successively younger birth cohorts and for all age groups over period progressing.

Sexual health in women with Sjogren's syndrome: A review

BACKGROUND

Rheumatic diseases, mainly affecting women, including rheumatoid arthritis, Sjogren's syndrome, systemic lupus erythematosus, etc., are chronic, inflammatory, autoimmune disorders that may involve multiple organs or systems and are closely related to sexual health, which is an important aspect of human physical and mental health. Sjogren's syndrome (SS) is the second most common rheumatic illnesses after rheumatoid arthritis with a female predominance. At present, the research on sexual health of female SS patients is still scarce and difficult to summarize.

OBJECTIVES

The objective of our study was to systematically review the literature for the influence of maternal SS on sexual health, such as sexual function, sex hormones, fertility, and pregnancy outcomes.

METHODS

We performed a comprehensive literature search based on PubMed and Web of science databases from inception to 1 November 2022. Outcomes were divided into 4 categories: sex hormones, sexual function, fertility, and pregnancy and offspring outcomes.

RESULTS

A total of 756 potentially eligible papers were retrieved. After eliminating duplicate articles and reviewing the titles and abstracts to exclude records, we read the remaining 92 articles in full for further evaluation, and selected 42 studies. Results on sex hormones, sexual function, fertility and pregnancy and offspring outcomes were reported in 13, 12, 3 and 14 SS-related articles, respectively. The levels of some sex hormones in SS patients may have undergone changes. Female patients with SS have a high prevalence of sexual dysfunction compared with controls. Most studies suggested SS had an adverse impact on maternal and fetal outcomes following pregnancy. However, there is insufficient evidence that directly indicating the fertility of SS women is diminished.

CONCLUSIONS

In summary, certain aspects of sexual health (sexual function, sex hormones and pregnancy outcomes) are impaired in SS women. Screening for sexual health problems in SS female should become an integral part of medical clinical practice. Rheumatologists should be aware of this association and collaborate with gynecologists, obstetricians, psychologists, and other experts on this issue to determine appropriate therapeutic approaches.

Association between disease activity of rheumatoid arthritis and maternal and fetal outcomes in pregnant women: a systematic review and meta-analysis

BACKGROUND

A meta-analysis has compared the pregnancy outcomes between women with and without RA, while the effect of disease severity on pregnancy outcomes within women with RA has not been explored. Therefore, we performed a systematic review and meta-analysis to assess the association between disease activity of RA and pregnancy outcomes.

METHODS

Four English databases (Pubmed, Embase, Cochrane Library, and Web of Science) and three Chinese databases (China National Knowledge Infrastructure [CNKI], VIP, and Wan Fang) was searched for eligible studies up to August 13, 2023. Cochran's Q test and the I2 statistic were used to assess the heterogeneity of the included studies. The odds ratio (OR) (for counting data) and weighted mean difference (WMD) (for measurement data) were calculated with 95% confidence intervals (95%CIs) using random-effect model (I2 ≥ 50%) or fixed-effect model (I2 < 50%). Subgroup analysis based on study design and regions was used to explore the sources of heterogeneity. Sensitivity analysis was performed for all outcomes and the publication bias was assessed using Begg's test.

RESULTS

A total of 41 eligible articles were finally included. RA women had higher odds to suffer from preeclampsia, gestational diabetes, spontaneous abortion, and cesarean delivery (all P < 0.05). The infants born from RA mother showed the higher risk of stillbirth, SGA, LBW, congenital abnormalities, diabetes type 1, and asthma (all P < 0.05). The high disease activity of RA was significantly associated with the higher risk of cesarean delivery (OR: 2.29, 95%CI: 1.02-5.15) and premature delivery (OR: 5.61, 95%CI: 2.20-14.30).

CONCLUSIONS

High disease activity of RA was associated with the high risk of adverse pregnancy outcomes, suggesting that it was important to control disease for RA women with high disease activity who prepared for pregnancy.

The dichotomy of glucocorticosteroid treatment in immune-inflammatory rheumatic diseases: an evidence-based perspective and insights from clinical practice

Objectives

Glucocorticosteroids (GCs) are the most used anti-inflammatory and immunosuppressive drugs due to their effectiveness in managing pain and disease modification in many immune-inflammatory rheumatic diseases (IRDs). However, their use is limited because of adverse effects (AEs).

Material and methods

The authors analyzed recent studies, including randomized controlled trials (RCTs), observational, translational studies and systematic reviews, providing an in-depth viewpoint on the benefits and drawbacks of GC use in rheumatology.

Results

Glucocorticosteroids are essential in managing life-threatening autoimmune diseases and a cornerstone in many IRDs given their swift onset of action, necessary in flares. Several RCTs and meta-analyses have demonstrated that when administered over a long time and on a low-dose basis, GC can slow the radiographic progression in early rheumatoid arthritis (RA) patients by at least 50%, satisfying the conventional definition of a disease-modifying anti-rheumatic drug (DMARD). In the context of RA treatment, the use of modified-release prednisone formulations at night may offer the option of respecting circadian rhythms of both inflammatory response and HPA activation, thereby enabling low-dose GC administration to mitigate nocturnal inflammation and prolonged morning fatigue and joint stiffness. Long-term GC use should be individualized based on patient characteristics and minimized due to their potential AEs. Their chronic use, especially at medium/high dosages, might cause irreversible organ damage due to the burden of metabolic systemic effects and increased risk of infections. Many international guidelines recommend tapering/withdrawal of GCs in sustained remission. Treat-to-target (T2T) strategies are critical in setting targets for disease activity and reducing/discontinuing GCs once control is achieved.

Conclusions

Glucocorticosteroids' use in treating IRDs should be judicious, focused on minimizing use, tapering and discontinuing treatment, when possible, to improve long-term safety. Glucocorticosteroids remain part of many therapeutic regimens, particularly at low doses, and elderly RA patients, especially with associated chronic comorbidities, may benefit from long-term low-dose GC treatment. A personalized GC therapy is essential for optimal long-term outcomes.

Maternal-fetal outcomes in patients with immune mediated inflammatory diseases, with consideration of comorbidities: a retrospective cohort study in a large U.S. healthcare system

Background

Immune-mediated inflammatory diseases (IMIDs) are likely to complicate maternal health. However, literature data on patients with IMIDs undergoing pregnancy is scarce and often overlooks the impact of comorbidities.

Methods

We investigated 12 selected IMIDs: psoriasis, inflammatory bowel disease, rheumatoid arthritis, spondyloarthritis, multiple sclerosis, systemic lupus erythematosus, psoriatic arthritis, antiphospholipid syndrome, Sjögren's syndrome, vasculitis, sarcoidosis, systemic sclerosis. We characterized patients with IMIDs prior to pregnancy (IMIDs group) based on pregnancy/maternal characteristics, comorbidities, and pre-pregnancy/prenatal immunomodulatory medications (IMMs) prescription patterns. We 1:1 propensity score matched the IMIDs cohort with people who had no IMID diagnoses prior to pregnancy (non-IMIDs cohort). Outcome measures were preterm birth (PTB), low birth weight (LBW), small for gestational age (SGA), and cesarean section.

Findings

The prevalence rate of pregnancy occurring with people with a previous IMID diagnosis has doubled in the past ten years. We identified 5,784 patients with IMIDs. 17% of the IMIDs group had at least one prenatal IMM prescription. Depending on the type of IMM, from 48% to 70% of the patients taking IMMs before pregnancy continued them throughout pregnancy. Patients with IMIDs had similar but slightly increased risks of PTB (Relative risk (RR)=1·1[1·0, 1·3]), LBW (RR=1·2 [1·0,1·4]), SGA (RR=1·1 [1·0,1·2]), and cesarean section (RR=1·1 [1·1,1·2]) compared to a matched cohort of people without IMIDs. Out of the 12 selected IMIDs, three for PTB, one for LBW, two for SGA, and six for cesarean section had results supporting increased risk.

Interpretation

The association between IMIDs and the increased risk of adverse pregnancy outcomes depend on both the nature of the IMID and the presence of comorbidities.

How Much Is an Abortion Worth? Was a Human "Not Formed"? An Italian Proposal

INTRODUCTION

"Human capital" is defined as an integration of innate skills and knowledge acquired by investing in the formation of an individual; it is a real "capital" that pays off in the long term. In the Italian legal system, a human being is recognised as a "person" from the moment of birth. This determines the acquisition of the personal rights of an individual. Necessarily, therefore, by law, a fetus does not own such rights; nevertheless, it has an innate "potential" to acquire such rights after birth.

OBJECTIVE

In Italian jurisprudence, in general, the damage from a loss of a parental relationship is justified by the condition of existential emptiness caused in the family by the loss of a child. Compensation for this damage in the event of abortion due to third-party responsibility presents a non-uniform recognition in the judgements of the Italian courts, but in any case, it is almost always recognised with limitations since the emotional relationship with the lost individual is defined only in terms of "potential". Consequently, in this matter, at least two questions can be raised: (i) Is the economic estimate of abortion based on objective and standardised criteria, or is it heavily influenced by subjective evaluation?

Literature Review: The sFlt1/PlGF Ratio and Pregestational Maternal Comorbidities: New Risk Factors to Predict Pre-Eclampsia

One of the main causes of maternal and neonatal morbidity and mortality is pre-eclampsia. It is characterized by a high sFlt1/PlGF ratio, according to prior research. Pregestational diseases in mothers may increase the risk of developing pre-eclampsia. Only a few studies have looked at the connection between maternal comorbidities before conception and the sFlt1/PlGF ratio. The most recent information regarding the association between maternal pregestational diseases and the ratio of sFlt1/PlGF is described in this review. The paper also examines current research suggesting that changes in pregnancy hormones and metabolites are related to a high sFlt1/PlGF ratio. Certain maternal disorders have been found to dramatically raise sFlt-1 and sFlt1/PlGF levels, according to an analysis of the literature. There is still debate about the data on the association between the sFlt1/PlGF ratio and maternal disorders such as HIV, acute coronary syndromes, cardiovascular function in the mother between 19 and 23 weeks of pregnancy, thyroid hormones, diabetes, and cancer. Additional research is needed to confirm these findings.
