Adverse Impact of Rheumatoid Arthritis on Pregnancy Outcomes: A Saudi Arabia Prospective Multicenter Study

Rheumatoid arthritis-associated complications during pregnancy and its effect on offspring: comprehensive review

This study comprehensively explores the complexities of rheumatoid arthritis during pregnancy and its impact on offspring. Through an extensive review of existing literature, we investigate maternal and fetal risks, including adverse pregnancy outcomes and developmental issues in offspring. Utilizing reputable databases such as PubMed, Google Scholar, and Science Direct, we meticulously examined studies exploring the connection between rheumatoid arthritis and pregnancy complications, with a focus on outcomes for offspring. We excluded studies lacking sufficient data or peer review. Synthesizing findings from selected studies, we identified common themes and patterns, presenting results in a clear, organized manner. Our examination reveals a heightened likelihood of preterm birth and preeclampsia among pregnant individuals with rheumatoid arthritis, often correlated with disease activity. Furthermore, we highlight the impact on fetal and neonatal outcomes, such as low birth weight, underscoring the importance of meticulous disease management throughout pregnancy. Balancing the necessity of disease-modifying agents with potential risks, and consideration of medication safety is paramount. A multidisciplinary approach involving rheumatologists and obstetricians is crucial for optimizing outcomes. In conclusion, this synthesis underscores the nuanced challenges of rheumatoid arthritis in pregnancy. A comprehensive understanding and personalized, multidisciplinary approach to an organization is essential for informed decision-making in clinical practice. Our review contributes to ongoing discourse, providing insights for enhanced patient care and guiding future research endeavors.

Patients with autoimmune skin diseases are at increased risk of adverse pregnancy outcomes

BACKGROUND

Increased rates of adverse pregnancy outcomes have been reported in association with rheumatologic diseases such as systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis. However, little is known about pregnancy outcomes in patients with autoimmune skin diseases.

OBJECTIVE

This study aimed to determine the frequency of adverse pregnancy outcomes in patients with autoimmune skin diseases. We hypothesized that similar to rheumatic diseases, the rate of adverse pregnancy outcomes in patients with autoimmune skin diseases would be higher than the general population.

STUDY DESIGN

This is a case control study using the TriNetX US Collaborative Network, which is a database of electronic medical records of >95 million patients seen at 57 healthcare organizations in the United States. All pregnant women between the ages of 15 and 44 years who were seen at a healthcare organization between January 1, 2016 and December 31, 2021 were included. Participants with autoimmune skin disease were matched to healthy controls and controls with systemic rheumatologic conditions (systemic lupus erythematosus or rheumatoid arthritis). For both the autoimmune skin disease and healthy control groups, those with systemic rheumatologic condition or hidradenitis suppurativa were excluded. The primary outcomes were adverse pregnancy outcomes defined as spontaneous abortion, gestational hypertension, preeclampsia or eclampsia, gestational diabetes mellitus, intrauterine growth restriction, preterm premature rupture of membranes, preterm birth, and stillbirth. Patients with autoimmune skin diseases and controls were 1:1 propensity score-matched by age, race, ethnicity, comorbidities, obesity, and substance use. For each outcome, odds ratio with a 95% confidence interval was calculated.

RESULTS

A total of 2788 patients with autoimmune skin diseases were matched to 2788 healthy controls. Patients with autoimmune skin diseases were at a higher risk of spontaneous abortions than controls (odds ratio, 1.54; 95% confidence interval, 1.36-1.75; P<.001). Compared with patients with systemic lupus erythematosus, patients with autoimmune skin diseases were at lower risk of having infants with intrauterine growth restriction (odds ratio, 0.59; 95% confidence interval, 0.4-0.87; P=.01), preterm birth (odds ratio, 0.68; 95% confidence interval, 0.47-0.98; P=.04), and stillbirth (odds ratio, 0.50; 95% confidence interval, 0.25-0.97; P=.04). The differences in adverse pregnancy outcomes between patients with autoimmune skin diseases and those with rheumatoid arthritis were not statistically significant.

CONCLUSION

Patients with autoimmune skin diseases are at a higher risk of spontaneous abortions than patients without autoimmune skin diseases. When analyzed by each autoimmune skin disease, patients with cutaneous lupus erythematosus or vitiligo remained at increased risk of spontaneous abortions compared with patients without autoimmune skin diseases. Patients with autoimmune skin diseases have similar risks of adverse pregnancy outcomes as patients with rheumatoid arthritis, but lower risks than patients with systemic lupus erythematosus.

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.

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.

Rheumatoid arthritis and the risk of preterm birth

During pregnancy, many diseases are correlated with different adverse outcomes. In turn, pregnancy affects the body, leading to increased disease susceptibility. This interplay between diseased states and pregnancy outcomes is illustrated in the effect of the chronic autoimmune disorder, rheumatoid arthritis (RA), and the adverse outcome, preterm birth (PTB). RA is a systemic disorder characterized by inflammation of the joints and other body organs. Joint pain and swelling are the most prominent manifestations of RA during pregnancy. However, the exact role of RA on PTB among pregnant women has yet to be established. This review highlighted the immunologic mechanisms involved in PTB in pregnant patients with RA. The immune cell population in pregnant women with RA exhibited higher activity of macrophages, dendritic cells, neutrophils, helper T (Th) 1 cells, and Vδ1 cells, but lower activity of CD4 + CD25^high T regulatory (CD24 + CD25^high T_reg ), Th2, and Vδ2 cells. Increased pro-inflammatory cytokines IL-6, TNF-α, and IFN-γ and decreased anti-inflammatory cytokines IL-12 and IL-10 are also exhibited by pregnant patients with RA. This review also discussed factors that may predict the risk of PTB in RA. These include disease activity and severity of RA, laboratory parameters (cytokines and immune cell population), and sociodemographic factors such as ethnicity, smoking, alcohol intake, and the level of education. Current findings on the underlying immunological mechanisms of RA can help identify possible strategies to prevent PTB.

The impact of preconception counselling on maternal and fetal outcomes in women with chronic medical conditions: A systematic review

BACKGROUND

Beyond diabetes mellitus little data reports outcomes of women with chronic medical conditions who have received pre-conception counselling (PCC). This study aimed to perform a systematic review of the literature to evaluate evidence regarding the impact of PCC on maternal and fetal outcomes in women with chronic medical conditions aside from diabetes mellitus.

METHODS

A systematic review was conducted in accordance with PRISMA. PubMed, Cochrane, Ovid Medline and Web of Science were searched. Two reviewers screened abstracts and full texts. Inclusion criteria included studies relating to chronic medical disorders of interest published between database inception and 21^st May 2022, reporting outcomes relating to disease activity and perinatal outcomes.

RESULTS

The search yielded 11,814 results of which six met criteria for inclusion. Two papers describe the demographics of women more likely to receive PCC which included younger age, shorter disease duration, nulliparity, IVF pregnancy and higher education/job security. Two reported the effects of PCC on women's behaviour with improvements demonstrated in correct medication adherence, folic acid intake and smoking cessation. Five studies reported outcomes related to disease activity; those receiving PCC were more likely to have quiescent disease during pregnancy. Improvements in pregnancy outcomes were described including reduced rates of small for gestational age, low birth weight, preterm birth, congenital abnormality and obstetric complications.

DISCUSSION

A paucity of data exists relating to pregnancy outcomes in women with chronic medical conditions receiving PCC. Reported outcomes are favorable, supporting the routine inclusion of PCC in preparation for pregnancy in such patients.

Pregnancy Outcomes in Women With Rheumatoid Arthritis: A Systematic Review and Meta-analysis

ABSTRACT

Rheumatoid arthritis (RA) is a chronic inflammatory rheumatic disease affecting multiple joints and can also be a systemic widespread, affecting major organs. Rheumatoid arthritis is associated with greater adverse maternal and neonatal outcomes in comparison to the general obstetric population. This systematic review and meta-analysis aims to investigate the pregnancy outcomes in RA patients in comparison to the general pregnant population.Nine studies involving 11,999 RA patients met the eligibility criteria with 9,921,808 controls. Rheumatoid arthritis patients were compared with their control counterparts according to random-effects model statistical analysis.We searched databases from inception to September 8, 2021. Eligible studies reported maternal outcomes (preeclampsia, cesarean delivery, and preterm delivery) and/or neonatal outcomes. Data were pooled across using random-effects model. Subgroup analysis was conducted on RA patients alone. The review was registered prospectively with PROSPERO (CRD42021250521).In terms of maternal outcomes, there was an increased rate of cesarean delivery (odds ratio [OR], 1.55), preeclampsia (OR, 1.61), and preterm delivery (OR, 1.83) in RA patients compared with their control counterparts. In terms of neonatal outcomes, a higher rate of lower gestational weight (mean difference [MD], -0.19 kg), requirement for neonate intensive care unit admission (OR, 1.34), and stillbirths (OR, 1.99) were observed in RA patients compared with the controls. A subgroup analysis of 4 studies involving only RA patients (n = 3761) was conducted. A total of 33.2% of patients had a cesarean delivery, 7.3% had preeclampsia, 14.8% had a preterm delivery, and 9.5% of neonates had low birth weight.Compared with the general pregnant population, women with RA tend to have a higher risk of maternal and neonatal complications. As a result, this study hopes to increase awareness into the importance of counseling and managing RA patients.

Risk factors for adverse pregnancy outcomes in women with rheumatoid arthritis and follow-up of their offspring

OBJECTIVE

To explore the risk factors for adverse pregnancy outcomes (APOs) in women with rheumatoid arthritis (RA) and the influence on their offspring health.

METHODS

Pregnant women with RA (n = 67) who were hospitalized in the Department of Obstetrics, Peking University People's Hospital between January 2007 and September 2021 were included in this study. Participants were evaluated at least once in each trimester and postpartum. Fetal outcomes and RA disease activity were extracted from medical records, and the offspring of enrolled patients were followed up. Associations between RA disease activity, medication use, and pregnancy outcomes were analyzed.

RESULTS

The incidence of APOs in our cohort was 43.3%. Postpartum hemorrhage (20.9%) was the commonest complication, followed by premature delivery (11.9%). Previous miscarriages [odds ratio (OR): 1.869, 95% confidence interval (CI): 1.053-3.318, P = 0.033] and antinuclear antibody (ANA) positivity (OR:3.168, 95% CI: 1.068-9.768, P = 0.045) were risk factors for APOs. Compared to patients with APOs, the remission rate of disease activity during pregnancy was higher in patients without APOs (P = 0.027). There were no significant differences between patients with and without APOs with respect to daily and cumulative doses of prednisone (P > 0.05). The average age of the offspring was 4.9 years (range 0.3-14 years). Long-term follow-up showed no significant differences in offspring health between the two groups (P > 0.05).

CONCLUSION

Previous miscarriages and ANA positivity are independent risk factors for APOs in RA patients, while adverse pregnancy outcomes and low-dose prednisone have no effect on offspring health. Key points • Previous miscarriages and ANA positivity are risk factors for APOs in RA patients. • Adverse pregnancy outcomes and low-dose prednisone during pregnancy have no effect on offspring health.
