Obstetric and neonatal complications among women with autoimmune disease

Systemic lupus erythematosus is associated with an increased frequency of spontaneous preterm births: systematic review and meta-analysis

OBJECTIVE

Preterm birth is one of the most frequent complications of pregnancy in women with systemic lupus erythematosus. The high indicated preterm birth proportion due to hypertensive disorders of pregnancy and/or fetal growth restriction is well known, and preventive measures and screening for early detection are performed. The risk of spontaneous preterm birth is less well recognized. This study aimed to determine the proportions of spontaneous and indicated preterm birth in pregnancies of women with systemic lupus erythematosus.

DATA SOURCES

A systematic literature search using Pubmed, Embase, Web of Science, and Google Scholar was performed in June 2021.

STUDY ELIGIBILITY CRITERIA

Studies in pregnant women with systemic lupus erythematosus reporting spontaneous and indicated preterm birth rates were selected. Original research articles published from 1995 to June 2021 were included.

METHODS

Quality and risk of bias of the included studies were assessed using the Newcastle-Ottawa quality assessment scale. To estimate the pooled event rates and 95% confidence intervals, meta-analysis of single proportions with a random-effects model was performed.

RESULTS

We included 21 articles, containing data of 8157 pregnancies in women with systemic lupus erythematosus. On average, 31% (95% prediction interval, 0.14-0.50) of the pregnancies resulted in preterm birth, including 14% (95% prediction interval, 0.04-0.27) spontaneous and 16% (95% prediction interval, 0.03-0.35) indicated preterm birth.

CONCLUSION

In pregnant women with systemic lupus erythematosus, spontaneous and indicated preterm birth proportions are high. This information should be applied in (prepregnancy) counseling and management in pregnancy. The knowledge obtained by this meta-analysis paves the way for further research of associated risk factors and development of interventions to reduce spontaneous preterm birth in systemic lupus erythematosus pregnancies.

Female fertility preservation for family planning: a position statement of the Italian Society of Fertility and Sterility and Reproductive Medicine (SIFES-MR)

PURPOSE

This position statement by the Italian Society of Fertility and Sterility and Reproductive Medicine (SIFES-MR) aims to establish an optimal framework for fertility preservation outside the standard before oncological therapies. Key topics include the role of fertility units in comprehensive fertility assessment, factors impacting ovarian potential, available preservation methods, and appropriate criteria for offering such interventions.

METHODS

The SIFES-MR writing group comprises Italian reproductive physicians, embryologists, and scientists. The consensus emerged after a six-month period of meetings, including extensive literature review, dialogue among authors and input from society members. Final approval was granted by the SIFES-MR governing council.

RESULTS

Fertility counselling transitions from urgent to long-term care, emphasizing family planning. Age, along with ovarian reserve markers, is the primary predictor of female fertility. Various factors, including gynecological conditions, autoimmune disorders, and prior gonadotoxic therapies, may impact ovarian reserve. Oocyte cryopreservation should be the preferred method. Women 30-34 years old and 35-39 years old, without known pathologies impacting the ovarian reserve, should cryopreserve at least 12-13 and 15-20 oocytes to achieve the same chance of a spontaneous live birth they would have if they tried to conceive at the age of cryopreservation (63% and 52%, respectively in the two age groups).

CONCLUSIONS

Optimal fertility counselling necessitates a long-term approach, that nurtures an understanding of fertility, facilitates timely evaluation of factors that may affect fertility, and explores fertility preservation choices at opportune intervals.

Pregnancies in patients with systemic lupus erythematosus during 2000-2018 in Finland: a case-control study

OBJECTIVES

The aim was to investigate, how pregnancies proceed in patients with systemic lupus erythematosus (SLE) compared to their individually matched population controls.

MATERIAL AND METHODS

Adult incident SLE patients were identified from the register of new special reimbursement decisions for SLE drugs in 2000-2014. For each patient, 1-3 randomly selected controls from the Population Register Centre were matched. Data regarding pregnancies were obtained from the Finnish Medical Birth Register, Care Register and Register of Congenital Malformations until 2018. The study utilized data from the Drug Purchase Register and educational information from Statistic Finland.

RESULTS

A total of 163 deliveries for 103 mothers with SLE and 580 deliveries for 371 population controls were identified. The duration of pregnancies in SLE women was significantly shorter compared to controls (38.9 versus 39.6 weeks). There were more urgent Caesarean Sections. (15% versus 9%) and need for care at neonatal intensive care unit (NICU) (21% versus 11%) among deliveries in SLE mothers. No statistical difference was observed between SLE and control groups in the occurrence of preeclampsia or major congenital malformations. Gestational age was 2.5 weeks shorter when the mother experienced pre-eclampsia. Hydroxychloroquine was purchased by 30% of SLE mothers during pregnancy.

CONCLUSION

The course of pregnancies in Finnish SLE patients seems to be quite moderate compared to controls, and no new safety issues were detected. The low utilization of hydroxychloroquine indicates that the benefits of the drug to pregnancy and disease course are not optimally recognized by specialists treating SLE mothers.

Abnormal neutrophil-to-lymphocyte ratio in children with autism spectrum disorder and history of maternal immune activation

Maternal immune activation (MIA), related to autoimmune/inflammatory diseases or acute infections, during the two first trimesters of pregnancy is a risk factor for autism spectrum disorders (ASD) in offspring. In mice, MIA has a long-term impact on offspring's immune equilibrium resulting in a pro-inflammatory phenotype. We therefore hypothesized that children with ASD and a history of MIA could display a similar phenotype specifically assessed by a higher neutrophil to lymphocyte ratio (NLR). In this study, we used a retrospective sample of 231 dyads involving children with ASD and their mothers. Among ASD patients, 12% had a history of MIA. The multivariate analysis revealed a significant association between NLR in children with ASD and maternal history of MIA (F = 2.27, p = 0.03). Using a categorical approach, we observed an abnormal NLR (over 3) in 7.4% of children with ASD MIA+ compared to 1.9% for MIA-. Our study supports the hypothesis suggesting an impact of MIA on the risk of ASD. Further studies could contribute to the development of biomarkers in MIA+ ASD and enable the development of targeted immunomodulatory therapies.

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

OBJECTIVE

Rheumatoid arthritis (RA) is a common chronic systemic autoimmune disease affecting women of childbearing age. We aimed to conduct a meta-analysis of published observational studies to systematically evaluate the association between RA and adverse pregnancy outcomes.

METHODS

Medline (PubMed), EMBASE, and Web of Science were searched for keywords from the date of inception to December 28, 2021, to identify relevant studies reporting adverse maternal and/or fetal outcomes in RA pregnancies. Data from individual studies were pooled using random-effects models and presented as odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS

Eighteen studies with a total number of over 50 million participants were eligible for inclusion. This current analysis showed that in pregnant women with RA, there was a significantly increased risk of adverse maternal outcomes, including caesarean section (OR, 1.39; 95% CI 1.24-1.55), pre-eclampsia (OR, 1.48; 95% CI 1.19-1.83), gestational hypertension (OR, 1.34; 95% CI 1.07-1.68) and spontaneous abortion (OR, 1.16; 95% CI 1.04-1.29). Similarly, maternal RA during pregnancy was also associated with a significantly increased risk of adverse fetal outcomes, including preterm birth (OR, 1.58; 95% CI 1.44-1.74), small for gestational age (OR, 1.49; 95% CI 1.22-1.82), low birth weight (OR, 1.45; 95% CI 1.30-1.63), congenital anomalies (OR, 1.36; 95% CI 1.01-1.83) and stillborn (OR, 1.38; 95% CI 1.09-1.74).

CONCLUSION

Maternal RA is significantly associated with an increased risk of adverse maternal and fetal outcomes. Close monitoring of the clinical status of RA patients before and during pregnancy is essential in clinical practice. Key Points • Pregnant women with rheumatoid arthritis (RA) are at significantly increased risk for adverse maternal and fetal outcomes. • The increased risk of adverse pregnancy outcomes in women with RA may be closely related to medication use and disease activity. • Close monitoring of the clinical status of RA patients before and during pregnancy is essential in clinical practice.

Treatment patterns and outcomes in patients with chronic urticaria during pregnancy: Results of PREG-CU, a UCARE study

BACKGROUND

Although chronic urticaria (CU) is a common and primarily affects females, there is little data on how pregnancy interacts with the disease.

OBJECTIVE

To analyse the treatment use by CU patients before, during and after pregnancy as well as outcomes of pregnancy.

METHODS

PREG-CU is an international, multicentre study of the Urticaria Centers of Reference and Excellence network. Data were collected via a 47-item-questionnaire completed by CU patients who became pregnant during their disease course.

RESULTS

Questionnaires from 288 CU patients from 13 countries were analysed. During pregnancy, most patients (60%) used urticaria medication including standard-dose second generation H1-antihistamines (35.1%), first generation H1-antihistamines (7.6%), high-dose second-generation H1-antihistamines (5.6%) and omalizumab (5.6%). The preterm birth rate was 10.2%; rates were similar between patients who did and did not receive treatment during pregnancy (11.6% vs. 8.7%, respectively). Emergency referrals for CU and twin birth were risk factors for preterm birth. The caesarean delivery rate was 51.3%. More than 90% of new-borns were healthy at birth. There was no link between any patient or disease characteristics or treatments and medical problems at birth.

CONCLUSION

Most CU patients used treatment during pregnancy especially second-generation antihistamines which seem to be safe during pregnancy regardless of the trimester. The rates of preterm births and medical problems of new-borns in CU patients were similar to population norms and not linked to treatment used during pregnancy. Emergency referrals for CU increased the risk of preterm birth and emphasize the importance of sufficient treatment to keep urticaria under control during pregnancy.

Thymic and extrathymic Aire-expressing cells in maternal-fetal tolerance

Healthy pregnancy requires maternal immune tolerance to both fetal and placental tissues which contain a range of self- and non-self-antigens. While many of the components and mechanisms of maternal-fetal tolerance have been investigated in detail and previously and thoroughly reviewed (Erlebacher A. Annu Rev Immunol. 2013;31:387-411), the role of autoimmune regulator (Aire), a critical regulator of central tolerance expressed by medullary thymic epithelial cells (mTECs), has been less explored. Aire is known to facilitate the expression of a range of otherwise tissue-specific antigens (TSAs) in mTECs, and here we highlight recent work showing a role for mTEC-mediated thymic selection in maintaining maternal-fetal tolerance. Recently, however, our group and others have identified additional populations of extrathymic Aire-expressing cells (eTACs) in the secondary lymphoid organs. These hematopoietic antigen-presenting cells possess the ability to induce functional inactivation and/or deletion of cognate T cells, and deletion of maternal eTACs during pregnancy increases T-cell activation in the lymph nodes and lymphocytic infiltration of the uterus, leading to pregnancy complications including intrauterine growth restriction (IUGR) and fetal resorption. In this review, we briefly summarize findings related to essential Aire biology, discuss the known roles of Aire-deficiency related to pregnancy complications and infertility, review the newly discovered role for eTACs in the maintenance of maternal-fetal tolerance-as well as recent work defining eTACs at the single-cell level-and postulate potential mechanisms by which eTACs may regulate this process.

Pregnancy Outcome in Women With APECED (APS-1): A Multicenter Study on 43 Females With 83 Pregnancies

CONTEXT

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; also known as autoimmune polyendocrine syndrome type 1) has a severe, unpredictable course. Autoimmunity and disease components may affect fertility and predispose to maternal and fetal complications, but pregnancy outcomes remain unknown.

OBJECTIVE

To assess fetal and maternal outcomes and course of clinical APECED manifestations during pregnancy in women with APECED.

DESIGN AND SETTING

A multicenter registry-based study including 5 national patient cohorts.

PATIENTS

321 females with APECED.

MAIN OUTCOME MEASURE

Number of pregnancies, miscarriages, and deliveries.

RESULTS

Forty-three patients had altogether 83 pregnancies at median age of 27 years (range, 17-39). Sixty (72%) pregnancies led to a delivery, including 2 stillbirths (2.4%) and 5 (6.0%) preterm livebirths. Miscarriages, induced abortions, and ectopic pregnancies were observed in 14 (17%), 8 (10%), and 1 (1.2%) pregnancies, respectively. Ovum donation resulted in 5 (6.0%) pregnancies. High maternal age, premature ovarian insufficiency, primary adrenal insufficiency, or hypoparathyroidism did not associate with miscarriages. Women with livebirth had, on average, 4 APECED manifestations (range 0-10); 78% had hypoparathyroidism, and 36% had primary adrenal insufficiency. APECED manifestations remained mostly stable during pregnancy, but in 1 case, development of primary adrenal insufficiency led to adrenal crisis and stillbirth. Birth weights were normal in >80% and apart from 1 neonatal death of a preterm baby, no serious perinatal complications occurred.

CONCLUSIONS

Outcome of pregnancy in women with APECED was generally favorable. However, APECED warrants careful maternal multidisciplinary follow-up from preconceptual care until puerperium.

Adverse Perinatal Outcomes Before and After Diagnosis with Systemic Lupus Erythematosus Among African American Women

OBJECTIVE

Women with systemic lupus erythematosus (SLE) may experience adverse perinatal outcomes in the years before an SLE diagnosis. Overall, there is limited research on perinatal outcomes among African American women with SLE.

METHODS

Women with SLE identified from the Georgia Lupus Registry and the Georgians Organized Against Lupus Cohort were linked with birth certificates by the Georgia Department of Public Health. Births were categorized into occurring more than 3 years before SLE diagnosis, 0-3 years before SLE diagnosis, 0-3 years after SLE diagnosis or more than 3 years after SLE diagnosis. Comparison births certificates to African American women in the same geographic area were obtained from the National Center for Health Statistics. We used log-risk models to compare the risk of preterm birth or small-for-gestational age among SLE births in each diagnosis timing category to the general population, adjusting for maternal age and education and parity.

RESULTS

Births to women with SLE were more likely to occur preterm 0-3 years before SLE diagnosis (risk ratio [RR]: 1.71, 95% confidence interval [CI]: 1.24, 2.35), 0-3 years after SLE diagnosis (RR: 2.29, 95% CI: 1.70, 3.09) and 3 or more years after diagnosis (RR: 2.83, 95% CI: 2.36, 3.38), but not 3 or more years before SLE diagnosis compared to the general population (RR: 1.03, 95% CI: 0.77, 1.38). Similar results were observed for small-for-gestational age births.

CONCLUSION

Our analysis, conducted among African American women, demonstrates an increased risk of adverse perinatal outcomes even before a clinical diagnosis of SLE.

World Prematurity Day: it takes an NIH village to prevent preterm birth and improve treatments for preterm infants

Prematurity remains a major cause of morbidity and mortality. Research to prevent preterm birth and improve treatments for preterm infants involves both intramural and extramural research, not just at the National Institute of Child Health and Human Development, but across many institutes and centers at the National Institutes of Health.

Prevalence of autoimmune conditions in pregnant women in a tertiary maternity hospital: A cross-sectional survey and maternity database review

Background

Autoimmune conditions are associated with adverse pregnancy and offspring outcomes; however, the prevalence in pregnant women is not well understood. Estimates based on administrative data alone may underestimate prevalence.

Methods

A cross-sectional survey of women attending a tertiary referral hospital for antenatal care in December 2018-February 2019 and review of the hospital's maternity database of women giving birth from October 2017-June 2018 to estimate autoimmune disease prevalence.

Results

A total of 400 women completed surveys (78% response rate) and 41 (10.3%) reported an autoimmune disease, most commonly Hashimoto's thyroiditis (2.8%) and psoriasis (2.5%). From the maternity database, 112 of 2756 women giving birth (4.1%) had a recorded autoimmune disease, most commonly Hashimoto's thyroiditis (1.3%) followed by coeliac disease, Graves' disease, and immune thrombocytopenic purpura (all 0.4%).

Conclusion

Autoimmune disease prevalence in pregnant women is higher when self-reported and may be more common than previously reported using administrative data.

Air pollution exposure and risk of adverse obstetric and neonatal outcomes among women with type 1 diabetes

AIMS/HYPOTHESIS

Women with type 1 diabetes have increased risk for poor obstetric outcomes. Prenatal air pollution exposure is also associated with adverse outcomes for women and infants. We examined whether women with type 1 diabetes are more vulnerable than other women to pollution-associated risks during pregnancy.

METHODS

In singleton deliveries from the Consortium on Safe Labor (2002-2008), obstetric and neonatal outcomes were compared for women with type 1 diabetes (n = 507) and women without autoimmune disease (n = 204,384). Preconception, trimester, and whole pregnancy average air pollutant exposure (ozone (O₃), carbon monoxide (CO), particulate matter >10 μm (PM₁₀), PM > 2.5 μm (PM_2.5), sulfur dioxide (SO₂), nitrogen oxides (NO_x)) were estimated using modified Community Multiscale Air Quality models. Poisson regression models with diabetes*pollutant interaction terms estimated relative risks and 95% confidence intervals for adverse outcomes, adjusted for maternal characteristics and geographic region.

RESULTS

For whole pregnancy exposure to SO₂, women with type 1 diabetes had 15% increased risk (RR:1.15 95%CI:1.01,1.31) and women without autoimmune disease had 5% increased risk (RR:1.05 95%CI:1.05,1.06) for small for gestational age birth (p_interaction = 0.09). Additionally, whole pregnancy O₃ exposure was associated with 10% increased risk (RR:1.10 95%CI:1.02,1.17) among women with type 1 diabetes and 2% increased risk (RR:1.02 95%CI:1.00,1.04) among women without autoimmune disease for perinatal mortality (p_interaction = 0.08). Similar patterns were observed between PM_2.5 exposure and spontaneous preterm birth.

CONCLUSIONS

Pregnant women with type 1 diabetes may be at greater risk for adverse outcomes when exposed to air pollution than women without autoimmune disease.

Risk of adverse pregnancy outcomes in Japanese systemic lupus erythematosus patients with prior severe organ manifestations: A single-center retrospective analysis

BACKGROUND

Systemic lupus erythematosus (SLE) increases the incidence of adverse pregnancy outcomes (APOs). Nevertheless, most of the data on SLE pregnancies were derived from database studies in which details of the pregnancies were unavailable, and no consensus exists on the risk of APO in patients with prior severe organ manifestations.

METHODS

SLE patients followed by rheumatologists and gynecologists throughout pregnancy at our institute were retrospectively identified, and their data between April 2003 and December 2020 were reviewed from electronic records. We assigned patients based on the presence of prior severe organ manifestation (renal/neurological manifestation, prior treatment with methylprednisolone pulse therapy/prednisolone 1 mg/kg/day/biological or cytotoxic therapy) and compared the incidence of overall and serious APO (maternal death, pregnancy loss, preterm birth <32 weeks, birthweight <1500 g, Apgar score <7 at 5 min and birth defect).

RESULTS

This study included 34 pregnancies in 32 patients; 23 pregnancies in 22 patients were classified as SLE with prior severe organ manifestation. There was no statistical difference in the incidence of overall APO between the two groups (52.2% vs 45.5%, P = 1). Among patients with prior severe organ manifestation, 17.4% had serious APO. A detailed electronic health record search revealed specific causes of APO in all pregnancies with serious APO, except the presence of prior severe organ manifestation.

CONCLUSION

The incidence of overall APO in SLE patients was not affected by prior severe organ manifestation. Although the incidence of serious APOs increased in patients with previous severe organ manifestation, there were other risk factors for poor pregnancy outcomes besides prior lupus severity. Therefore, proper management by rheumatologists and gynecologists may enable patients with prior severe organ manifestation to safely deliver healthy babies.

Maternal autoimmunity and inflammation are associated with childhood tics and obsessive-compulsive disorder: Transcriptomic data show common enriched innate immune pathways

Although genetic variation is a major risk factor of neurodevelopmental disorders, environmental factors during pregnancy and early life are also important in disease expression. Animal models demonstrate that maternal inflammation causes fetal neuroinflammation and neurodevelopmental deficits, and brain transcriptomics of neurodevelopmental disorders in humans show upregulated differentially expressed genes are enriched in immune pathways. We prospectively recruited 200 sequentially referred children with tic disorders/obsessive-compulsive disorder (OCD), 100 autoimmune neurological controls, and 100 age-matched healthy controls. A structured interview captured the maternal and family history of autoimmune disease and other pro-inflammatory states. Maternal blood and published Tourette brain transcriptomes were analysed for overlapping enriched pathways. Mothers of children with tics/OCD had a higher rate of autoimmune disease compared with mothers of children with autoimmune neurological conditions (p = 0.054), and mothers of healthy controls (p = 0.0004). Autoimmunity was similarly elevated in first- and second-degree maternal relatives of children with tics/OCD (p < 0.0001 and p = 0.014 respectively). Other pro-inflammatory states were also more common in mothers of children with tics/OCD than controls (p < 0.0001). Upregulated differentially expressed genes in maternal autoimmune disease and Tourette brain transcriptomes were commonly enriched in innate immune processes. Pro-inflammatory states, including autoimmune disease, are more common in the mothers and families of children with tics/OCD. Exploratory transcriptome analysis indicates innate immune signalling may link maternal inflammation and childhood tics/OCD. Targeting inflammation may represent preventative strategies in pregnancy and treatment opportunities for children with neurodevelopmental disorders.

Maternal Morbidity and Mortality: Are We Getting to the "Heart" of the Matter?

Cardiovascular disease (CVD), including hypertensive disorders of pregnancy (HDP) and peripartum cardiomyopathy, is a leading cause of pregnancy-related death in the United States. Women who are African American or American Indian/Alaskan Native, have HDP, are medically underserved, are older, or are obese have a major risk for the onset and/or progression of CVD during and after pregnancy. Paradoxically, women with no preexisting chronic conditions or risk factors also experience significant pregnancy-related cardiovascular (CV) complications. The question remains whether substantial physiologic stress on the CV system during pregnancy reflected in hemodynamic, hematological, and metabolic changes uncovers subclinical prepregnancy CVD in these otherwise healthy women. Equally important and similarly understudied is the concept that women's long-term CV health could be detrimentally affected by adverse pregnancy outcomes, such as preeclampsia, gestational hypertension, and diabetes, and preterm birth. Thus, a critical life span perspective in the assessment of women's CV risk factors is needed to help women and health care providers recognize and appreciate not only optimal CV health but also risk factors present before, during, and after pregnancy. In this review article, we highlight new advancements in understanding adverse, pregnancy-related CV conditions and will discuss promising strategies or interventions for their prevention, diagnosis, and treatment.

Developing and Validating Methods to Assemble Systemic Lupus Erythematosus Births in the Electronic Health Record

OBJECTIVE

Electronic health records (EHRs) represent powerful tools to study rare diseases. We developed and validated EHR algorithms to identify SLE births across centers.

METHODS

We developed algorithms in a training set using an EHR with over 3 million subjects and validated algorithms at two other centers. Subjects at all 3 centers were selected using ≥ 1 SLE ICD-9 or SLE ICD-10-CM codes and ≥ 1 ICD-9 or ICD-10-CM delivery code. A subject was a case if diagnosed with SLE by a rheumatologist and had a birth documented. We tested algorithms using SLE ICD-9 or ICD-10-CM codes, antimalarial use, a positive antinuclear antibody ≥ 1:160, and ever checked dsDNA or complements using both rule-based and machine learning methods. Positive predictive values (PPVs) and sensitivities were calculated. We assessed the impact of case definition, coding provider, and subject race on algorithm performance.

RESULTS

Algorithms performed similarly across all three centers. Increasing the number of SLE codes, adding clinical data, and having a rheumatologist use the SLE code all increased the likelihood of identifying true SLE patients. All the algorithms had higher PPVs in African American vs. Caucasian SLE births. Using machine learning methods, total number of SLE codes and a SLE code from a rheumatologist were the most important variables in the model for SLE case status.

CONCLUSION

We developed and validated algorithms that use multiple types of data to identify SLE births in the EHR. Algorithms performed better in African American mothers than Caucasian mothers.

Maternal and infant outcomes in sarcoidosis pregnancy: a Swedish population-based cohort study of first births

Background

It is unclear whether sarcoidosis, a multisystem inflammatory disease, is associated with adverse pregnancy outcomes. We aimed to assess the risk of adverse maternal and infant outcomes in sarcoidosis pregnancies, focused on first births.

Methods

Using a population-based cohort study design and Swedish national registers (2002–2013), we identified 182 singleton first pregnancies in the Medical Birth Register with at least two maternal ICD-coded sarcoidosis visits prior to pregnancy in the National Patient Register. Modified Poisson regression models estimated relative risks (RR) of adverse outcomes in sarcoidosis pregnancies compared to the general population adjusted for maternal age at delivery, calendar year and educational level. Some models were additionally adjusted for maternal body mass index and smoking status.

Results

The prevalence of pre-existing diabetes and hypertension was higher in mothers with sarcoidosis than those without sarcoidosis. Mothers with sarcoidosis had an increased risk of preeclampsia/eclampsia (RR 1.6; 95%CI 1.0, 2.6) and cesarean delivery (RR 1.3; 95%CI 1.0, 1.6). There were < 5 stillbirths and cases of infection and no cases of placental abruption, venous thromboembolism, cardiac arrest or maternal death. Newborns of first-time mothers with sarcoidosis had a 70% increased risk of preterm birth (RR 1.7; 95%CI 1.1, 2.5). There was an increased risk of birth defects (RR 1.6; 95%CI 0.9, 2.8) the majority of which were non-cardiac.

Conclusions

Sarcoidosis is associated with increased risks for preeclampsia/eclampsia, cesarean delivery, preterm birth and some birth defects. Awareness of these conditions may prevent possible pregnancy complications in mothers with sarcoidosis and their newborns.

Family history of autoimmune disease in relation to time-to-pregnancy, pregnancy loss, and live birth rate

Several autoimmune conditions have adverse effects on reproductive outcomes, but the relationship between family history of autoimmune disease in women without these conditions and pregnancy is uncertain. The objective of this study was to determine if there is an association between a family history of an autoimmune condition and time-to-pregnancy (TTP), pregnancy loss, and live birth. This was a prospective cohort study from a RCT of 1228 adult women ages 18-40, who were healthy, had no history of infertility, were actively attempting to conceive, and had one or two prior pregnancy losses. Of these, 1172 women had data available regarding family history of autoimmune conditions. Women with an affected first-degree relative had similar TTP when compared to those without a FHx (fecundability odds ratio 0.90, 95% confidence interval [CI] 0.70, 1.15). Women with an affected first-degree relative had a lower likelihood of live birth (relative risk [RR] 0.83, 95% CI 0.69, 0.99). Among women who achieved pregnancy, FHx of autoimmune disease was associated with a higher likelihood of pregnancy loss (RR 1.49, 95% CI 1.10, 2.03). Women who had a first-degree relative with an autoimmune disease had a similar TTP as unaffected women but a lower likelihood of live birth and higher risk of pregnancy loss. This information may encourage clinicians to evaluate women with a family history of autoimmune conditions prior to pregnancy and highlights the need for further studies to ascertain the effects of autoimmunity and pregnancy.

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.
