OBJECTIVES:Our aim is to add to the limited existing prospective data on IL-1 inhibitor use in pregnancy. METHODS:Data were obtained from the Organization of Teratology Information Specialists Autoimmune Disease in Pregnancy Project, a prospective cohort study of pregnancy outcomes in the USA and Canada. Eligible women were enrolled prior to 19 weeks' gestation between 2004 and 2017. Outcomes were obtained by maternal interview and medical record abstraction. RESULTS:Five pregnancies with anakinra exposure were identified, all resulting in full-term singleton live births with no major or long-term complications. Three maternal subjects used anakinra for adult-onset Still's disease and two for systemic JIA. For all individuals who discontinued anakinra, some amount of steroid medication was necessary for treatment of disease flare. Two maternal subjects developed oligohydramnios, one also with pregnancy-induced hypertension. Two women had Caesarian sections, one medically indicated and one scheduled. One infant had low birth weight, but follow-up records indicated normal adjusted weight at 1 year. Three women successfully breastfed their infants, at least two of whom continued anakinra while breastfeeding. CONCLUSION:Anakinra was used successfully in five full-term pregnancies; however, two subjects developed oligohydramnios, a process that can be linked to fetal renal anomalies. Given previously reported cases of congenital renal anomalies associated with both antenatal anakinra use and maternal hyperthermia, the relationship between maternal IL-1 inhibitor use, uncontrolled maternal febrile disease and fetal outcomes should be further explored.

OBJECTIVE:Pregnant women with inflammatory arthritis may be at increased risk for preterm delivery (PTD), yet it is unclear what drives this risk. This aim of this prospective cohort study of pregnant women with rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), or healthier comparison women was to analyze the independent effects of maternal disease activity, medication use, and comorbid pregnancy conditions on PTD risk. METHODS:Women were enrolled before 19 weeks completed gestation as part of the Organization of Teratology Information Specialists (OTIS) Autoimmune Disease in Pregnancy Project. Data on pregnancy events, medications, disease activity, and outcomes were obtained by maternal report and validated by medical records. Poisson regression with robust standard errors estimated risk ratios (RR), multivariable adjusted risk ratios (ARRs), and 95% confidence intervals (95% CIs). RESULTS:A total of 657 women with RA, 170 with JIA, and 564 comparison women without autoimmune disease who delivered live born infants, from 2004 to 2017 were included for analysis. Both the RA and JIA groups had an increased risk of PTD versus the comparison group (RR 2.09 [95% CI 1.50-2.91] and RR 1.81 [95% CI 1.14-2.89], respectively). Active RA at enrollment (ARR 1.58 [95% CI 1.10-2.27]) and any time during pregnancy (ARR 1.52 [95% CI 1.06-2.18]) was associated with PTD. Corticosteroid use in every trimester was associated with an approximate 2- to 5-fold increased risk for PTD for both arthritis groups, independent of disease activity. CONCLUSION:Women with RA and women with JIA are at increased risk for PTD. Maternal disease activity and corticosteroid use may contribute to some of this excess risk.

OBJECTIVE: To add to data on adverse birth outcomes accounting for disease activity in women with psoriatic arthritis (PsA) and ankylosing spondylitis (AS). METHODS: Data were analyzed from women enrolled in the Organization of Teratology Information Specialists Autoimmune Disease Project from 2004 to 2018. Disease activity was measured according to the Health Assessment Questionnaire (HAQ) or Routine Assessment of Patient Index Data 3 (RAPID3) scores. Poisson regression was used to estimate adjusted risk ratios (ARRs) with 95% confidence intervals (95% CIs) for selected adverse pregnancy outcomes. RESULTS: Compared to healthy controls (n = 717), women with PsA (n = 117) were at increased risk for moderate preterm delivery (32-36 weeks gestation) (ARR 1.81, 95% CI 1.01-3.26), oligohydramnios (ARR 3.79, 95% CI 1.34-10.74), and cesarean delivery (ARR 1.63, 95% CI 1.26-2.12). Women with AS (n = 129) had an increased risk of delivering infants requiring intensive care (ARR 1.67, 95% CI 1.05-2.67). A high HAQ score at 32 weeks was associated with preterm delivery in women with PsA (ARR 3.82, 95% CI 1.51-9.67). In women with AS, a high RAPID3 score was associated with cesarean delivery (ARR 5.82, 95% 1.06-31.78), and second trimester glucocorticoid use was associated with preterm delivery (ARR 4.41, 95% CI 1.57-12.41). CONCLUSION: Women with PsA and AS have increased risk for selected adverse pregnancy outcomes. Active disease and use of glucocorticoids may increase the risk for some adverse pregnancy outcomes in women with these conditions.

Objectives

Most women may have temporary pain for which they use analgesics, but those with autoimmune disorders have chronic pain that may be exacerbated for some during pregnancy. This study aimed to determine whether prenatal acetaminophen use was associated with an increased risk of adverse pregnancy and birth outcomes in women with autoimmune disorders.

Methods

Participants were enrolled between 2004 and 2018 in the MotherToBaby cohort study and limited to women with an autoimmune disorder (n = 1821). Self-reported acetaminophen use was characterized over gestation for indication, timing of use and duration. Cumulative acetaminophen use through 20 and 32 weeks was categorized into quintiles, with no acetaminophen use as the reference category. The association between acetaminophen quintile and preeclampsia or pregnancy-induced hypertension, small for gestational age and preterm birth was examined using adjusted multiple log-linear regression.

Results

Overall, 74% of women reported acetaminophen use during pregnancy. The most often reported indication for using acetaminophen was headache/migraines, followed by pain and injury. Risk of preeclampsia was 1.62 (95% CI: 1.10, 2.40) times greater for those in the fifth quintile of cumulative acetaminophen use through 20 weeks compared with those with no acetaminophen use. There were no associations with lower use quintiles, nor for the other outcomes.

Conclusion

The highest quintile of cumulative acetaminophen was associated with a modestly increased risk for preeclampsia. Some women with autoimmune conditions have pain throughout pregnancy; clinicians and patients should discuss approaches to best avoid high levels of acetaminophen in their pain management strategies.

Objective

Poisson regression was used to estimate adjusted risk ratios (ARRs) with 95% confidence intervals (95% CIs) for selected adverse pregnancy outcomes.

Results

Compared to healthy controls (n = 717), women with PsA (n = 117) were at increased risk for moderate preterm delivery (32-36 weeks' gestation) (ARR 1.81, 95% CI 1.01-3.26), oligohydramnios (ARR 3.79, 95% CI 1.34-10.74), and cesarean delivery (ARR 1.63, 95% CI 1.26-2.12). Women with AS (n = 129) had an increased risk of delivering infants requiring intensive care (ARR 1.67, 95% CI 1.05-2.67). A high HAQ score at 32 weeks was associated with preterm delivery in women with PsA (ARR 3.82, 95% CI 1.51-9.67).

Conclusion

Women with PsA and AS have increased risk for selected adverse pregnancy outcomes. Active disease and use of glucocorticoids may increase the risk for some adverse pregnancy outcomes in women with these conditions.

OBJECTIVES: Up to a quarter of pregnant individuals with SLE have small for gestational age (SGA) infants. We aimed to characterize placental pathology associated with SGA infants in SLE. METHODS: We retrospectively analysed SLE deliveries with placental analysis at UCSD from November 2018 to October 2023, comparing SLE pregnancies resulting in SGA to those that did not, and additionally, to matched pregnancies with SGA but without SLE. RESULTS: Placental analysis was available only for 28/70 (40%) SLE deliveries, which had high rates of adverse outcomes (75%). All exhibited at least one histopathologic abnormality. Key findings distinguishing 12 SLE placentas resulting in SGA infants (vs.16 without) included small placental disc for gestational age (100% vs 56%, P = 0.01), placental disc infarct (50% vs 6%, P = 0.02) and increased perivillous fibrin deposition (PVFD, 58% vs 0%, P = 0.001). All seven SLE placentas with increased PVFD resulted in SGA infants. Compared with matched non-SLE pregnancies with SGA (n = 36), the only distinguishing placental lesion was a higher prevalence of increased PVFD in SLE-associated SGA (58% vs 22%, P = 0.03). CONCLUSION: The higher prevalence of increased PVFD in placentas of SLE-associated SGA may indicate a specific mechanism of placental injury leading to SGA in this context. Thus, its presence, particularly in context of SGA, should prompt providers to screen for an underlying autoimmune disease, including SLE. Systematic placental examination in context of SLE and associated autoimmune diseases could help evaluate responses to existing therapies, comparative studies of novel therapies and correlation to adverse outcomes.

The evidence to date regarding corticosteroid exposure in pregnancy and select pregnancy and birth outcomes is limited and inconsistent. The authors provide a narrative review of published literature summarizing the findings for oral clefts, preterm birth, birth weight, preeclampsia, and gestational diabetes mellitus. Whenever possible, the results are limited to oral or systemic administration with a further focus on use in autoimmune disease. Although previous studies of corticosteroid exposure in pregnancy reported an increased risk of oral clefts in the offspring, more recent studies have not replicated these findings.

Infantile hemangiomas (IHs) are the most common vascular tumors in infants, appearing in early infancy and ultimately regressing with time. Clinical presentation may vary, with a minority of lesions causing impairment of vital function (e.g., respiratory or visual obstruction), permanent scarring, and/or disfigurement. The pathogenesis of IH is complex and poorly understood. Risk factors implicated in their development include preterm birth and placental anomalies. IH presents a myriad of clinical challenges, including correct diagnosis and whether or not to pursue treatment. This article is a review of the current literature regarding pathogenesis, clinical presentation, treatment, and prognosis of IH.

The purpose of this study was to analyze the risk of maternal autoimmune disease or associated treatments on infantile hemangiomas (IHs), a common benign vascular tumor in infants, and to better understand how maternal chronic inflammation may play a factor in the pathogenesis of these lesions. Eligible women from the United States and Canada who enrolled before 19 weeks' gestation and delivered at least one live born infant were recruited as part of the Organization of Teratology Information Specialists (OTIS) Autoimmune Disease in Pregnancy Project from 2004-2013. A total of 51/969 (5.3%) and 8/240 (3.3%) infants with IH were born to mothers with and without autoimmune disease, respectively (OR 1.61; 95%CI, 0.75-.44). The presence of ulcerative colitis (UC) in the mother was significantly associated with IH in the child (OR 3.46; 95%CI, 1.29-9.26). The five largest IH occurred within the autoimmune disease cohort and to women taking a biologic medication. These results imply that UC may be a risk factor for IH development, and that chronic inflammation may influence the development of these lesions. This potential link between IH and autoimmune disease warrants further investigation.
