Abstract
ABSTRACT Autoimmune rheumatic diseases (ARDs) often affect women during their reproductive years, and early studies of pregnancy in these patients reported high rates of adverse outcomes. Continuation or initiation of safe and effective medications in the preconception period is beneficial for maintaining or achieving disease quiescence throughout pregnancy thereby improving both maternal and pregnancy outcomes. The European Alliance of Associations for Rheumatology, the American College of Rheumatology, and the British Society for Rheumatology have published recommendations and guidelines regarding management of ARDs during pregnancy. The American College of Obstetricians and Gynecologists and the American Gastroenterological Association have also provided guidance statements with relevant recommendations. This review provides an overview of available recommendations for medication use in ARD pregnancy, with discussion of safety considerations for maternal and fetal well-being. Medications considered compatible with pregnancy include hydroxychloroquine, sulfasalazine, azathioprine, cyclosporine, tacrolimus, and TNF inhibitors. Methotrexate, mycophenolate, leflunomide, and cyclophosphamide should be avoided before and during pregnancy. Other medications, most of them newer, are largely discouraged for use in pregnancy due to inadequate data or concerns for neonatal immunosuppression, including non-TNF biologics and small molecule therapies. Further investigation is needed regarding effects of non-TNF biologics, biosimilars, and small molecules in pregnancy. Important efforts for the future will include improved methodologies to gather critical safety data, with consideration of inclusion of pregnant women in clinical trials, a complex and controversial issue. Long-term information on outcomes in offspring of treated women is lacking for many of these medications.

J Clin Med 2024; 13:3454. [PMID: 38929983 PMCID: PMC11204490 DOI: 10.3390/jcm13123454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2024] [Revised: 06/05/2024] [Accepted: 06/12/2024] [Indexed: 06/28/2024] Open
Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that predominantly affects women of childbearing age. Pregnancy in SLE patients poses unique challenges due to the potential impact on maternal and fetal outcomes. We provide an overview of the management of SLE during pregnancy, including preconception risk stratification and counseling, treatment, and disease activity monitoring. These assessments are critical to minimize maternal and fetal adverse events in pregnant patients with SLE. Disease flares, preeclampsia, antiphospholipid syndrome complications, and maternal mortality are the major risks for a woman with SLE during gestation. Timely treatment of SLE relapse, differentiation of preeclampsia from lupus nephritis, and tailored management for antiphospholipid syndrome are essential for a successful pregnancy. Fetal outcomes include neonatal lupus (NL), preterm birth, cesarean delivery, fetal growth restriction (FGR), and small-for-gestational-age (SGA) infants. We focused on NL, linked to maternal anti-Ro/SS-A and anti-La/SS-B antibodies, which can lead to various manifestations, particularly cardiac abnormalities, in newborns. While there is a common consensus regarding the preventive effect of hydroxychloroquine, the role of echocardiographic monitoring and fluorinated steroid treatment is still debated. Finally, close postpartum monitoring and counseling for subsequent pregnancies are crucial aspects of care.

Abstract
OBJECTIVE To share our experience with belimumab in lupus pregnant women and to review the relevant published literature on its use in this scenario. METHODS A prospective observational study of pregnant patients with lupus was conducted. Additionally, MEDLINE and EMBASE databases were searched, and a secondary hand search of the literature was performed. Studies were evaluated and visualised descriptively. RESULTS Sixteen pregnancies of 12 lupus women were included, six (involving eight pregnancies) received belimumab throughout their illness, five of them during some period of gestation. In this group, there was one miscarriage, one elective termination and seven live foetuses (including two live twins). There was one type I intrauterine growth retardation, and a preterm pregnancy due to premature rupture of membranes (PPROM). One mild lupus flare was detected. There were no cases of pre-eclampsia, gestational diabetes mellitus or hypertension. All neonates had normal Apgar scores at birth, none needed critical care. There were no congenital anomalies. After the search, we identified 10 case reports and case series, and five registries. Among the 39 reported cases (41 pregnancies), there were 5 PPROM, 4 pre-eclampsia, and 1 eclampsia. All women made full recoveries. Nineteen new-borns had low birth weight. There were no malformations. While registries did not indicate an increased risk of birth defects or pregnancy loss, there was a higher risk of neonatal infections. CONCLUSIONS Belimumab may be an option for pregnant women with difficult-to-control lupus. Further research is needed to confirm the absence of association between belimumab and foetal harm.

Effect of remission, clinical remission with active serology, and glucocorticoid dosage on the pregnancy outcome of pregnant patients with systemic lupus erythematosus. Arthritis Res Ther 2024; 26:63. [PMID: 38459603 PMCID: PMC10924338 DOI: 10.1186/s13075-024-03298-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 02/29/2024] [Indexed: 03/10/2024] Open
Abstract
BACKGROUND Remission is a key treatment target in systemic lupus erythematosus (SLE) management. Given the direct correlation between lupus flares and elevated risks of adverse pregnancy outcomes (APOs), securing remission before conception becomes crucial. However, the association between clinical remission with active serology, and the risk of APOs is not thoroughly understood. Additionally, determining the optimal glucocorticoid dosage during pregnancy to mitigate APO risks remains under-researched. This study investigated the risk of APOs in relation to remission/serological activity status in patients in clinical remission/glucocorticoid dosage. METHODS Pregnant patients with SLE, who were followed up at two Japanese tertiary referral centers, and had their remission status assessed at conception, were included in this study. We categorized the patients into two groups based on whether they achieved Zen/Doria remission at conception and analyzed the APO ratio. We also examined the influence of serological activity in pregnant patients with clinical remission and analyzed the optimal glucocorticoid dosage to minimize the APO ratio. RESULTS Of the 96 pregnancies included, 59 achieved remission at conception. Pregnant patients who achieved remission showed a significant decrease in the APO ratio compared with those who did not. (overall APO: odds ratio (OR) 0.27, 95% confidence interval (CI) 0.11-0.65, p < 0.01, maternal APO: OR 0.34, 95%CI 0.13-0.85, p = 0.021, neonatal APO: OR 0.39, 95%CI 0.17-0.90, p = 0.028). Conversely, no statistical difference was observed in the APO ratio based on serological activity in pregnant patients with clinical remission. (overall APO: OR 0.62, 95%CI 0.21-1.79, p = 0.37, maternal APO: OR 1.25, 95%CI 0.32-4.85, p = 0.75, neonatal APO: OR 0.83, 95%CI 0.29-2.39, p = 0.73). A glucocorticoid dose of prednisolone equivalent ≥ 7.5 mg/day at conception correlated with increased APO. (overall APO: OR 3.01, 95%CI 1.23-7.39, p = 0.016, neonatal APO: OR 2.98, 95% CI:1.23-7.22, p = 0.016). CONCLUSIONS Even with active serology, achieving clinical remission can be a clinical target for reducing APOs in patients who wish to conceive. In addition, if clinically feasible, reducing the glucocorticoid dosage to < 7.5 mg/day before conception could be another predictive factor.

Nakai T, Honda N, Soga E, Fukui S, Kitada A, Yokogawa N, Okada M. A retrospective analysis of the safety of tacrolimus use and its optimal cut-off concentration during pregnancy in women with systemic lupus erythematosus: study from two Japanese tertiary referral centers. Arthritis Res Ther 2024; 26:15. [PMID: 38178242 PMCID: PMC10765865 DOI: 10.1186/s13075-023-03256-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 12/27/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND Tacrolimus is one of the major treatment options for systemic lupus erythematosus (SLE) and is considered to be a pregnancy-compatible medication. Since little is known about tacrolimus safety during pregnancy complicated by SLE, this study was designed. METHODS We included SLE pregnant patients who were followed up at two Japanese tertiary referral centers. We performed multivariate logistic regression analysis to assess each adverse pregnancy outcome (APO) risk. Moreover, we assessed the influence of tacrolimus on the APO ratio in pregnant patients with lupus nephritis, and the impact of combined tacrolimus-aspirin therapy on the APO ratio relative to patients exclusively administered tacrolimus. RESULTS Of the 124 pregnancies, 29 were exposed to tacrolimus. Multivariate analysis showed no statistical difference in APO ratio. (overall APO: adjusted odds ratio [aOR], 0.69; 95% confidence interval [CI], 0.23-2.03; p = 0.50; maternal APO: aOR, 1.17; 95% CI, 0.36-3.83; p = 0.80; neonatal APO: aOR, 1.10; 95% CI, 0.38-3.21; p = 0.86; PROMISSE APO: aOR, 0.50; 95% CI, 0.14-1.74; p = 0.27). Blood pressure and estimated glomerular filtration rate (eGFR) during pregnancy and after delivery did not differ between the two groups. Receiver operating characteristic (ROC) curve showed that tacrolimus concentration > 2.6 ng/ml was related to reduced preterm birth rate. (AUC = 0.85, 95% CI: 0.61-1.00, sensitivity: 93% and specificity: 75%). Regarding effect of tacrolimus on lupus nephritis during pregnancy, tacrolimus showed no increased risk of APO, blood pressure or eGFR during pregnancy and after delivery. (overall APO: OR, 1.00; 95% CI, 0.25-4.08; p = 0.98; maternal APO: OR 1.60, 95% CI, 0.39-6.64; p = 0.51; neonatal APO: OR, 0.71; 95% CI, 0.17-3.03; p = 0.65, PROMISSE APO: OR, 0.50; 95% CI, 0.08-3.22; p = 0.47). Tacrolimus-aspirin combination therapy showed a protective tendency against hypertensive disorders during pregnancy, preeclampsia and low birth weight. CONCLUSIONS Tacrolimus use during pregnancy with SLE and lupus nephritis showed no significant influence on APO, blood pressure, or renal function; therefore tacrolimus may be suitable for controlling lupus activity during pregnancy. In addition, when using tacrolimus during pregnancy, we should aim its trough concentration ≥ 2.6 ng/ml while paying careful attention to possible maternal side effects of tacrolimus. TRIAL REGISTRATION Retrospectively registered.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease which frequently affects women of childbearing age. Nowadays, pregnancy is not contraindicated in cases of well-controlled disease activity, but pregnancies are still at higher risk of maternal and fetal complications compared to the general population. During pregnancy and puerperium patients are at risk of disease flare, and obstetric complications are more frequent in cases of active disease at conception/beginning of pregnancy, a history of lupus nephritis, and concomitant presence of antiphospholipid syndrome. To improve pregnancy outcomes in SLE patients, appropriate preconception counseling with changes in medication, if necessary, and close rheumatological and obstetrical monitoring are fundamental. This review aims to summarize the risk factors for adverse pregnancy outcomes and provide an update on developments in medical care for pregnancy in SLE patients.

Abstract
Systemic lupus erythematosus (SLE) is a chronic, multisystem, inflammatory autoimmune disease characterized by relapses (commonly called "flares") and remission. Many organs may be involved, and although the manifestations are highly variable, the kidneys, joints, and skin are commonly affected. Immunologic abnormalities, including the production of antinuclear antibodies, are also characteristic of the disease. Maternal morbidity and mortality are substantially increased in patients with systemic lupus erythematosus, and an initial diagnosis of systemic lupus erythematosus during pregnancy is associated with increased morbidity. Common complications of systemic lupus erythematosus include nephritis, hematologic complications such as thrombocytopenia, and a variety of neurologic abnormalities. The purpose of this document is to examine potential pregnancy complications and to provide recommendations on treatment and management of systemic lupus erythematosus during pregnancy. The following are the Society for Maternal-Fetal Medicine recommendations: (1) we recommend low-dose aspirin beginning at 12 weeks of gestation until delivery in patients with systemic lupus erythematosus to decrease the occurrence of preeclampsia (GRADE 1B); (2) we recommend that all patients with systemic lupus erythematosus, other than those with quiescent disease, either continue or initiate hydroxychloroquine (HCQ) in pregnancy (GRADE 1B); (3) we suggest that for all other patients with quiescent disease activity who are not taking HCQ or other medications, it is reasonable to engage in shared decision-making regarding whether to initiate new therapy with this medication in consultation with the patient's rheumatologist (GRADE 2B); (4) we recommend that prolonged use (>48 hours) of nonsteroidal antiinflammatory drugs (NSAIDs) generally be avoided during pregnancy (GRADE 1A); (5) we recommend that COX-2 inhibitors and full-dose aspirin be avoided during pregnancy (GRADE 1B); (6) we recommend discontinuing methotrexate 1-3 months and mycophenolate mofetil/mycophenolic acid at least 6 weeks before attempting pregnancy (GRADE 1A); (7) we suggest the decision to initiate, continue, or discontinue biologics in pregnancy be made in collaboration with a rheumatologist and be individualized to the patient (GRADE 2C); (8) we suggest treatment with a combination of prophylactic unfractionated or low-molecular-weight heparin and low-dose aspirin for patients without a previous thrombotic event who meet obstetrical criteria for antiphospholipid syndrome (APS) (GRADE 2B); (9) we recommend therapeutic unfractionated or low-molecular-weight heparin for patients with a history of thrombosis and antiphospholipid (aPL) antibodies (GRADE 1B); (10) we suggest treatment with low-dose aspirin alone in patients with systemic lupus erythematosus and antiphospholipid antibodies without clinical events meeting criteria for antiphospholipid syndrome (GRADE 2C); (11) we recommend that steroids not be routinely used for the treatment of fetal heart block due to anti-Sjögren's-syndrome-related antigen A or B (anti-SSA/SSB) antibodies given their unproven benefit and the known risks for both the pregnant patient and fetus (GRADE 1C); (12) we recommend that serial fetal echocardiograms for assessment of the PR interval not be routinely performed in patients with anti-SSA/SSB antibodies outside of a clinical trial setting (GRADE 1B); (13) we recommend that patients with systemic lupus erythematosus undergo prepregnancy counseling with both maternal-fetal medicine and rheumatology specialists that includes a discussion regarding maternal and fetal risks (GRADE 1C); (14) we recommend that pregnancy be generally discouraged in patients with severe maternal risk, including patients with active nephritis; severe pulmonary, cardiac, renal, or neurologic disease; recent stroke; or pulmonary hypertension (GRADE 1C); (15) we recommend antenatal testing and serial growth scans in pregnant patients with systemic lupus erythematosus because of the increased risk of fetal growth restriction (FGR) and stillbirth (GRADE 1B); and (16) we recommend adherence to the Centers for Disease Control and Prevention medical eligibility criteria for contraceptive use in patients with systemic lupus erythematosus (GRADE 1B).

Abstract
INTRODUCTION Published data on the safety of biologics other than tumor necrosis factor (TNF) inhibitors during pregnancy are limited. OBJECTIVE The aim was to detect pharmacovigilance signals for fetal and neonatal adverse drug reactions (ADRs) to biologics taken by pregnant women with autoimmune diseases. METHODS We performed a disproportionality analysis of the World Health Organization's VigiBase® pharmacovigilance database from 1968 to June 1, 2021. Data were collected in June 2021. By using terms for different hierarchical levels of the Medical Dictionary for Regulatory Activities, we selected the following fetal or neonatal ADRs: stillbirth, premature birth, low birth weight, small for gestational age, and congenital malformations. The frequency of all identified ADRs for biologics of interest (adalimumab, infliximab, golimumab, certolizumab, etanercept, anakinra, canakinumab, tocilizumab, sarilumab, ustekinumab, guselkumab, secukinumab, ixekizumab, belimumab, abatacept, and rituximab) was compared with that of all other reports for all other drugs and quoted as the reporting odds ratio (ROR) [95% confidence interval]. Reports with known concomitant use of teratogenic drugs were excluded from the main analysis. Other analyses included ROR stratifications by therapeutic indication in the periods 1968-2021 and 2001-2021, and an analysis after excluding reports with steroids. RESULTS In the main analysis, the RORs were particularly high for musculoskeletal malformations with anakinra (7.18 [3.50-14.73]), canakinumab (19.54 [12.82-29.79]), and abatacept (5.09 [2.77-9.33]), and for immune system disorders with canakinumab (347.88 [217.9-555.50]) and rituximab (9.27 [2.95-29.15]). After the exclusion of reports with steroids, the ROR was significant for neonatal infections with belimumab (28.49 [5.75-141.25]). CONCLUSION We identified possible associations with some adverse fetal and neonatal outcomes, suggesting that vigilance is required when prescribing certain biologics during pregnancy.
