The importance of pregnancy planning in lupus pregnancies

Issues with pregnancy in systemic lupus

Systemic lupus erythematosus is a disease that affects a large number of young women of childbearing age. Today, pregnancy is considered safe in almost all women with lupus, especially when the disease is under control. However, pregnancies in this population have a higher risk of maternal complications than in the general population. It is therefore important to plan pregnancies as effectively as possible, using effective contraception and pre-pregnancy counselling. In fact, effective, well-tolerated contraception is essential for patients for whom pregnancy cannot be safely envisaged, particularly in the setting of teratogenic treatment or significant disease activity. Preconception counselling is essential and helps to anticipate several aspects of a future pregnancy. Several recent prospective studies have clearly identified risk factors for obstetric complications and disease flare. High level of lupus activity, low complement, primigravida and a history of lupus nephritis are predictive factors of disease flare when antiphospholipid syndrome or antiphospholipid antibodies (specifically for lupus anticoagulant), damage, activity of lupus are predictive for obstetric events. Appropriate therapeutic management is essential, based primarily on the continuation of hydroxychloroquine, although some recent warnings about its use in pregnancy have been discussed controversially. Corticosteroid therapy can be continued at the lowest possible dose, as can certain immunosuppressive drugs. In the case of a history of lupus nephritis, low-dose aspirin is also prescribed. Although still exceptional, the risk of neonatal lupus is also higher, in patients with anti-SSA and anti-SSB antibodies. The aim of this review is to summarise the risk factors for adverse obstetric outcomes and to improve medical and obstetric management in this population of pregnant women with lupus.

Pregnancy planning may impact maternal and neonatal outcomes in people with myasthenia gravis

INTRODUCTION

Myasthenia Gravis (MG) is an acquired autoimmune condition commonly diagnosed in young people of reproductive age resulting in neuromuscular junction dysfunction. The course of MG during pregnancy and its impact on maternal and neonatal outcomes is vary in the literature. Pregnancy planning is a known strategy and modifiable risk factor in obstetric practice to decrease maternal and neonatal morbidity. We aim to assess if planning a pregnancy impacts maternal and neonatal outcomes, MG exacerbation, and pregnancy-related complications.

METHODS

This study utilized data from an online, North American survey entitled "A Patient Centered study on Pregnancy in People with Myasthenia Gravis", distributed with the assistance of MG advocacy groups in the United States and Canada. It included individuals with MG who had at least one pregnancy in the last 10-years. Key maternal and neonatal outcomes were compared between planned and unplanned pregnancies.

RESULTS

Out of 156 survey participants, 58 had a pregnancy following MG diagnosis, totaling 90 reported pregnancies. Of these, 56 (62.2%) were planned and 34 (37.8%) were unplanned pregnancies. The unplanned pregnancies were associated with more MG exacerbations, hospitalizations, and intensive care unit admission (37.7% vs. 13.7%, 26.5% vs. 11%, and 17.6% vs. 8.9%, respectively, p ≤ .05). The neonatal outcomes did not significantly differ between the groups.

DISCUSSION

Planned pregnancies in people with MG may be associated with a reduced gestational and post-partum risk of MG exacerbation, hospitalizations, and ICU admissions. Larger studies are required to confirm this association and account for potential contributing variables.

Pre-pregnancy planning for female patients seen at a pregnancy and rheumatic diseases clinic: a retrospective analysis of patients with rheumatic diseases seeking pregnancy-related care

To assess the clinical utility of pre-pregnancy planning among female patients with rheumatic diseases attending a targeted pregnancy and rheumatic diseases clinic. We conducted a retrospective review using data collected via chart review of female patients with rheumatic diseases seen at the Pregnancy and Rheumatic Diseases Clinic at the Mary Pack Arthritis Centre in Vancouver, Canada, between January 2017 and July 2020. Patients were categorized according to an initial presentation at the clinic as (1) pregnant without pre-pregnancy planning; and (2) not pregnant with pre-pregnancy planning. The latter group was further categorized according to whether they had contraindications to pregnancy. Pregnancy outcomes were extracted from electronic medical records and analyzed using descriptive statistics. Our study included 230 female patients with rheumatic diseases. At the initial clinical presentation, 86 were pregnant and 144 were planning to become pregnant and presenting for pre-pregnancy planning. Compared to patients without pre-pregnancy planning, patients who received pregnancy planning experienced fewer prenatal disease flares (61.3% [38/62] vs. 22.6% [7/31]; p < 0.001), fewer medication changes during pregnancy (46.4% [39/84] vs. 18.9% [10/53]; p = 0.002), and improved disease control in the first trimester of pregnancy (p = 0.018). There were no statistically significant differences in the frequency of adverse pregnancy or fetal outcomes between patients with and without pre-pregnancy planning. Evaluation of patient outcomes suggests that pre-pregnancy planning may support early assessment of high-risk pregnancy status; therein, allowing healthcare providers to identify and manage risk factors for adverse pregnancy outcomes among patients living with rheumatic diseases.

Identifying pregnancy episodes and estimating the last menstrual period using an administrative database in Korea: an application to patients with systemic lupus erythematosus

OBJECTIVES

This study developed an algorithm for identifying pregnancy episodes and estimating the last menstrual period (LMP) in an administrative claims database and applied it to investigate the use of pregnancy-incompatible immunosuppressants among pregnant women with systemic lupus erythematosus (SLE).

METHODS

An algorithm was developed and applied to a nationwide claims database in Korea. Pregnancy episodes were identified using a hierarchy of pregnancy outcomes and clinically plausible periods for subsequent episodes. The LMP was estimated using preterm delivery, sonography, and abortion procedure codes. Otherwise, outcome-specific estimates were applied, assigning a fixed gestational age to the corresponding pregnancy outcome. The algorithm was used to examine the prevalence of pregnancies and utilization of pregnancy-incompatible immunosuppressants (cyclophosphamide [CYC]/mycophenolate mofetil [MMF]/methotrexate [MTX]) and non-steroidal anti-inflammatory drugs (NSAIDs) during pregnancy in SLE patients.

RESULTS

The pregnancy outcomes identified in SLE patients included live births (67%), stillbirths (2%), and abortions (31%). The LMP was mostly estimated with outcome-specific estimates for full-term births (92.3%) and using sonography procedure codes (54.7%) and preterm delivery diagnosis codes (37.9%) for preterm births. The use of CYC/MMF/MTX decreased from 7.6% during preconception to 0.2% at the end of pregnancy. CYC/MMF/MTX use was observed in 3.6% of women within 3 months preconception and 2.5% during 0-7 weeks of pregnancy.

CONCLUSIONS

This study presents the first pregnancy algorithm using a Korean administrative claims database. Although further validation is necessary, this study provides a foundation for evaluating the safety of medications during pregnancy using secondary databases in Korea, especially for rare diseases.

The impact of pregnancy planning and medical readiness on reproductive outcomes in women with systemic lupus erythematosus

Women with systemic lupus erythematosus (SLE) who get pregnant while SLE is active or while on teratogens have higher risk of poor pregnancy outcomes. The American College of Rheumatology (ACR) Reproductive Health Guidelines recommend women conceive when SLE is well controlled and treated with pregnancy-compatible medications. The Healthy Outcomes in Pregnancy with SLE Through Education of Providers (HOP-STEP) Intervention was created to ascertain pregnancy interest and contraceptive use followed by a personalized pregnancy prevention and/or planning discussion (https://www.LupusPregnancy.org). All study participants were adult females enrolled in a prospective registry who met ACR or SLICC criteria. Women were defined as "not medically ready for pregnancy" if they were currently prescribed a teratogen, had proteinuria ≥500 mg, or had elevated SLE activity according to the physician's global assessment. Two time periods were assessed: 2/2018-12/2019 and 10/2020-4/2021 to evaluate pre- and post-pandemic periods, with some post-pandemic visits taking place via telehealth. The interest in pregnancy was similar between the first time period (17%) and the second time period, whether in-person (18%) or virtual (18%). Pregnancy interest was assessed significantly more frequently during in-person visits (90%) compared to virtual encounters (67%) (p = .02). Contraceptive use was not significantly different during either time period with use of a teratogen or increased SLE activity. Of the 52 women in both time periods who were not medically ready for pregnancy and were not on effective contraception, three women (5.8%) conceived. None of the women who were using moderate or highly effective contraception became pregnant. Pregnancy outcomes were similar between unintended or high-risk and well-timed pregnancies. The HOP-STEP Intervention effectively identified pregnancy interest, giving rheumatologists the opportunity to address patient reproductive goals, optimize disease activity, and adjust medication regimens prior to conception.

2022 Chinese guideline for the management of pregnancy and reproduction in systemic lupus erythematosus

Systemic lupus erythematosus (SLE), a prevalent autoimmune disease predominantly affecting women of childbearing age, presents ongoing challenges despite notable advances in diagnosis and treatment. Although survival rates for SLE patients have significantly improved, pregnancy continues to pose a considerable obstacle. Addressing this critical need for enhanced reproductive and prenatal care, there is a pressing imperative to establish standardized protocols for peri-gestational monitoring and treatment in SLE patients. This guideline is jointly sponsored by the National Clinical Research Center for Dermatologic and Immunologic Diseases (NCRC-DID), the Chinese Systemic Lupus Erythematosus Treatment and Research Group (CSTAR), and the Chinese Research Committee of Pregnancy and Reproduction in Autoimmune Rheumatic Diseases (CHOPARD). Thirteen pertinent clinical questions have been generated through several rounds of rigorous clinical and methodological expert discussions and selections for a comprehensive understanding of key aspects in this domain. Guided by thorough examination of research evidence and expert perspectives, the formulated recommendations aim to optimize pregnancy success rates, reduce maternal and infant mortality rates, and ultimately enhance the overall well-being of SLE patients.

Immunological disease activity parameters at conception are risk factors for preterm birth and low birth weight in patients with systemic lupus erythematosus

OBJECTIVE

This study aimed to identify which disease activity parameters may be risk factors for preterm birth (PB) and low birth weight (LBW) in patients with systemic lupus erythematosus (SLE). We also analyzed the extent to which these parameters affected PB and LBW.

METHODS

We collected the SLE Disease Activity Index (SLEDAI), the rate of lupus low disease activity state (LLDAS) attainment, complement levels, and the titer of anti-double stranded DNA (dsDNA) antibody as disease activity parameters. We retrospectively analyzed the associations of these parameters with PB and LBW.

RESULTS

Sixty pregnancies were included in this study. C3 levels and anti-dsDNA antibody titers at conception were strongly associated with PB (p = 0.03 and p = 0.01, respectively), whereas C3 and CH50 levels were associated with LBW (p = 0.02 and p = 0.03, respectively). A logistic regression analysis showed that the cutoff values of C3 and anti-dsDNA antibody for PB were 62.0 mg/dl and 5.4 IU/ml, respectively. The cutoff values of C3 and CH50 for LBW were 87.0 mg/dl and 41.8 U/ml, respectively. The risk of PB or LBW was increased when divided by the cutoff value, and the combination of these cutoff values showed a significantly higher risk of PB and LBW (p = 0.01 and p < 0.01, respectively).

CONCLUSIONS

PB and LBW are strongly associated with disease activity parameters in patients with SLE. Therefore, strictly monitoring and controlling these disease activity parameters, with or without clinical manifestation, is important for women who want to become mothers.

Pregnancy Outcomes in Patients With Interstitial Lung Disease

OBJECTIVE

Women with interstitial lung disease (ILD) are recommended to avoid pregnancy based on limited data. This study seeks to determine maternal and pregnancy outcomes in the largest-to-date cohort of patients with ILD.

METHODS

Medical records in the Duke University Health System were reviewed for pregnancies in patients with a diagnosis of ILD with underlying autoimmune disease. Pregnancies were classified as having very severe, severe, mild-moderate, or normal lung function based on pulmonary function tests (PFTs). Adverse pregnancy outcomes (APOs) were defined using the Predictors of Pregnancy Outcome in Systemic Lupus Erythematosus and Antiphospholipid Syndrome APO (PROMISSE-APO) and Severe PROMISSE-APO criteria.

RESULTS

Among 86 pregnancies in 60 women, 85% women were Black, 71% had sarcoidosis, and 29% had connective tissue disease (CTD)-associated ILD (CTD-ILD). Of the pregnancies with available PFTs (n = 59), 12% had very severe ILD, 25% had severe ILD, 51% had mild-moderate ILD, and 12% had normal lung function. PROMISSE-APOs occurred in 32% of pregnancies, including all pregnancies with very severe ILD (P = 0.02 across severity groups), 56% of pregnancies with CTD-ILD, and 23% with sarcoidosis (P = 0.02). Severe PROMISSE-APOs occurred in 15% of pregnancies, including 60% with very severe ILD and 28% with CTD-ILD. There were no maternal deaths. One woman required an intensive care hospital stay during pregnancy. Three women had volume overload after delivery that resolved with medical management. Seven women received oxygen during delivery, although none were intubated.

CONCLUSION

Although APOs were common in women with very severe ILD and underlying CTD, overall maternal morbidity and mortality were low. These data suggest women with ILD may be able to safely attempt pregnancy.

Pregnancy outcomes among Egyptian women with systemic lupus erythematosus: A prospective cohort study

Pregnant patients with systemic lupus erythematosus (SLE) represent a high-risk group. The aim of this study is to describe the pregnancy outcomes among SLE patients who were followed prospectively at a conjoint high-risk pregnancy/rheumatology clinic from 2007 to 2021 and to identify predictors of adverse maternal and fetal outcomes. This study included 201 singleton pregnancies of 123 women with SLE. Their mean age was 27.16 ± 4.80 years, and their mean disease duration was 7.35 ± 5.46 years. Secondary antiphospholipid syndrome (APS) was diagnosed in 77 (38.3%) pregnancies. The pregnancy was planned in 104 (51.7%) pregnancies. Flares occurred in 83 (41.3%) and pre-eclampsia in 15 (7.5%) pregnancies. Full-term pregnancy occurred in 93 (46.3%), fetal loss (miscarriage and intra-uterine fetal death) in 41 (20.4%), and prematurity in 67 (33.3%) of the pregnancies, respectively. Seven neonates died from complications of prematurity, and another one died from cardiac congenital anomalies. In the multivariate analyses, unplanned pregnancy was associated with eight times higher risk of disease flare OR = 7.92 (p < 0.001), lupus nephritis flare during pregnancy increased the odds of pre-eclampsia occurrence four times OR = 3.98 (p = 0.02), while disease flares during pregnancy predicted prematurity OR = 2.49, p = 0.049. Patients with secondary APS had three times increased risk of fetal loss OR = 2.97, p = 0.049. To conclude, unplanned pregnancy, disease flares, and APS have been identified as predictors for adverse maternal and/or fetal outcomes. Pregnancy planning is necessary to reduce maternal and fetal complications.

Frequency of Contraception Documentation in Women With Systemic Lupus Erythematosus and Rheumatoid Arthritis Within the Rheumatology Informatics System for Effectiveness Registry

OBJECTIVE

We sought to understand the frequency of contraception documentation for women with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) in a large US electronic health record (EHR)-based registry and to identify disparities by teratogen prescription and patient race and ethnicity.

METHODS

Contraception documentation from structured data fields within the Rheumatology Informatics System for Effectiveness (RISE) registry was collected for women of childbearing age (18-45 years) in 2018 who had at least 2 visits with International Classification of Diseases, Ninth Revision or Tenth Revision, diagnosis codes for SLE or RA (at any time). Univariate and multivariate analyses compared the frequency of contraception documentation based on patient characteristics including diagnosis, age, race, and teratogenicity of prescribed antirheumatic medications.

RESULTS

In 2018, there were 9,826 women of childbearing age with SLE and 19,009 with RA, of whom 9.1% had any contraception documented. Rates of contraceptive documentation were significantly lower for women with SLE (adjusted odds ratio [OR] 0.84 [95% confidence interval (95% CI) 0.76-0.92]). Women of Hispanic ethnicity and Black and Asian race were all less likely than White women to have contraception documentation. Teratogen prescription was associated with higher rates of contraception documentation for women with RA but not SLE (RA adjusted OR 1.31 [95% CI 1.16-1.47]; SLE adjusted OR 1.08 [95% CI 0.91-1.28]).

CONCLUSION

There are large gaps in contraception documentation within the RISE registry that are particularly stark among women of color. Although these data likely underestimate contraception use, they highlight that most rheumatologists do not have a systematic approach to collecting and recording this information in the EHR.

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.

Teratogenic medication use associated with favourable odds of contraception counselling in a cohort of women with systemic lupus erythematosus at a large tertiary academic medical centre

OBJECTIVE

SLE primarily affects women of childbearing age, who have an increased risk of pregnancy complications, especially in the setting of active disease. Contraception counselling is particularly important given the teratogenicity of some medications used for SLE treatment. Our study describes the frequency of contraception counselling provided by multiple subspecialties to women with SLE and investigates associations between teratogenic medication use and receiving contraception counselling.

METHODS

This was a cross-sectional retrospective study of women (aged 15-46 years) diagnosed with SLE who were seen in various outpatient clinics at a large tertiary academic medical centre over a 2-year period. Demographic data were retrieved via the university-affiliated central data repository, and additional data, including documentation of contraception counselling, were obtained via manual chart abstraction. Univariable associations between variables and contraception counselling were assessed to produce unadjusted ORs and 95% CIs. Multivariable models were generated to evaluate independent associations between variables and contraception counselling.

RESULTS

Data from 478 women (52% African American, 25% Caucasian) with SLE were included. Rheumatology was the subspecialty to document contraception counselling most frequently (57%). Nearly 80% of women received counselling from at least one subspecialty, 44% from at least two. Factors associated with having lower odds of receiving contraception counselling were older age and Caucasian race. Women on teratogenic medications (methotrexate, mycophenolate mofetil/mycophenolic acid, cyclophosphamide) had higher odds of receiving contraception counselling from at least one subspecialty (OR 2.01; 95% CI 1.23 to 3.26), from two or more subspecialties (OR 2.18; 95% CI 1.50 to 3.17), and from rheumatology (OR 1.86; 95% CI 1.27 to 2.73).

CONCLUSIONS

In this study, women with SLE on teratogenic medications had higher odds of receiving contraception counselling from rheumatology and from at least two subspecialties. Multidisciplinary approaches to enhance contraception counselling should be encouraged.

Preparing for Pregnancy in Women with Systemic Lupus Erythematosus—A Multidisciplinary Approach

Pregnancy is one of the most challenging processes the human body is exposed to: the healthy mother can carry to term a genetically different new-born, while her immune system adapts to tolerate this new status and avoids rejection. In autoimmune disorders, motherhood is even more challenging, with additional medical counselling, mother care, and foetus development checks being necessary. While the aspects of supplementary mother care and pregnancy progress tracking are associated with well-established medical procedures and protocols, counselling, be it pre- or post-conception, is still underestimated and scarcely applied. Indeed, over the past decades, medical counselling for this particular population has changed significantly, but from a healthcare’s provider point of view, more is required to ensure a smooth, controllable pregnancy evolution. One of the most frequent autoimmune diseases affecting young females during their fertile years is Systemic Lupus Erythematosus (SLE). Like other heterogenous diseases, it exposes the mother to severe, organ-threatening complications and unpredictable evolution. Both the disease and its treatment can significantly affect the mother’s willingness to engage in a potentially risky pregnancy, as well as the likeliness to carry it to term without any impairments. A good collaboration between the patient’s rheumatologist and obstetrician is therefore mandatory in order to: (a) allow the mother to make an informed decision on pursuing with the pregnancy; (b) ensure a perfect synchronization between pregnancy terms and treatment; and (c) avoid or minimize potential complications. The best approach to achieve these outcomes is pregnancy planning. Moreover, knowing one desired prerequisite for a successful pregnancy evolution in SLE mothers is a stable, inactive, quiescent disease for at least six months prior to conception, planning becomes more than a recommended procedure. One particular aspect that requires attention before conception is the treatment scheme applied before delivery as autoantibodies can influence significantly the course of pregnancy. In this view, future SLE mothers should ideally benefit from preconception counselling within their agreed care pathway. A multidisciplinary team including at least the rheumatologist and obstetrician should be employed throughout the pregnancy, to decide on the appropriate timing of conception and compatible medication with respect to disease activity, as well as to monitor organ involvement and foetus development progress.

Predictors Associated with Adverse Pregnancy Outcomes in a Cohort of Women with Systematic Lupus Erythematosus from Romania-An Observational Study (Stage 2)

Background: Pregnancy in women with systemic lupus erythematosus (SLE) is accompanied by adverse pregnancy outcomes (APOs). We aimed to investigate the association between clinical, sonographic, and laboratory parameters and APOs (preeclampsia, intrauterine growth restriction, premature birth, and maternal mortality). Methods: This observational retrospective study included all pregnancies in women with SLE who attended two tertiary maternity hospitals from Romania between January 2013 and December 2020. Clinical, sonographic, and laboratory variables were examined. Bivariate associations of APO status and each predictor variable were evaluated, and significant predictors were further included in a classification model based on discriminant analysis. Results: Predictors of APOs included BMI > 25 kg/m2, personal history of lupus nephritis or chronic hypertension, proteinuria, low C3, SLE Disease Activity Index 2000 (SLEDAI-2k score ≥ 4 and physician’s global-assessment (PGA) score ≥ 1 throughout pregnancy, increased mean uterine arteries pulsatility index in the first and second trimesters, cerebroplacental ratio < 1 in the second and third trimesters, and small fetal abdominal circumference in the third trimester. Glucocorticoids, methyldopa, and aspirin use appeared to be protective against APOs. Conclusions: This study provides a comprehensive analysis of the most important predictors for APOs in pregnant patients with SLE, which could constitute a basis for further research.

A glimpse into the future of systemic lupus erythematosus

This viewpoint article on a forecast of clinically meaningful changes in the management of systemic lupus erythematosus (SLE) in the next 10 years is based on a review of the current state of the art. The groundwork has been laid by a robust series of classification criteria and treatment recommendations that have all been published since 2019. Building on this strong foundation, SLE management predictably will take significant steps forward. Assessment for lupus arthritis will presumably include musculoskeletal sonography. Large-scale polyomics studies are likely to unravel more of the central immune mechanisms of the disease. Biomarkers predictive of therapeutic success may enter the field; the type I interferon signature, as a companion for use of anifrolumab, an antibody against the common type I interferon receptor, is one serious candidate. Besides anifrolumab for nonrenal SLE and the new calcineurin inhibitor voclosporin in lupus nephritis, both of which are already approved in the United States and likely to become available in the European Union in 2022, several other approaches are in advanced clinical trials. These include advanced B cell depletion, inhibition of costimulation via CD40 and CD40 ligand (CD40L), and Janus kinase 1 (Jak1) and Tyrosine kinase 2 (Tyk2) inhibition. At the same time, essentially all of our conventional therapeutic armamentarium will continue to be used. The ability of patients to have successful SLE pregnancies, which has become much better in the last decades, should further improve, with approaches including tumor necrosis factor blockade and self-monitoring of fetal heart rates. While we hope that the COVID-19 pandemic will soon be controlled, it has highlighted the risk of severe viral infections in SLE, with increased risk tied to certain therapies. Although there are some data that a cure might be achievable, this likely will remain a challenge beyond 10 years from now.

Mobile Responsive App-A Useful Additional Tool for Data Collection in the German Pregnancy Register Rhekiss?

Background: The German pregnancy register Rhekiss is designed as a nationwide, web-based longitudinal observational cohort established in 2015. The register follows women with inflammatory rheumatic disease prospectively from child wish or early pregnancy until 2 years post-partum. Information on clinical and laboratory parameters, drug treatment, and (adverse) pregnancy outcomes are documented in pre-specified intervals. Physicians and patients report data for the same time periods via separated accounts and forms into a web-based application (app). As data entry on mobile devices might improve response rates of patients, a responsive app as a further convenient documentation option was developed.

Methods: The Rhekiss-app is available for self-reported data retrieval since August 2017 from the App stores. For the current analysis, Rhekiss register data were used from the start of the register until 30 September 2020. The analyses were performed for forms containing information on devices. Outcome parameters were compared for mobile and desktop users for the quantity and quality of filled forms.

Results: In total, 5,048 forms were received and submitted by 966 patients. About 57% of forms were sent from mobile devices with the highest numbers in patients with child wishes (63%). Users of mobile devices were slightly younger and often had less high-education level (62 vs. 79%) compared with desktop users. The proportion of forms submitted via mobile devices increased steadily from 48% in the fourth quarter of 2018 to 64% in the third quarter of 2020. The proportion of forms received before and after the Rhekiss-app implementation increased with the highest increase of 12% for forms filled at time point 12 months post-partum. Mobile users submitted significantly more forms than desktop users (2.9 vs. 2.1), data sent via desktops were more often complete (88 vs. 86%).

Conclusion: The responsive app is a valuable additional tool for data collection and is well-accepted by patients as indicated by its increasing use in Rhekiss. Apart from desktop/browser developments, the technological adoptions within observational cohorts and registries should take smartphone requirements and developments into account, especially when patient-reported data in young, mobile patients are collected, bearing in mind that data quality could be compromised and concepts for improving data quality should be implemented.

Hydroxychloroquine PK and exposure-response in pregnancies with lupus: the importance of adherence for neonatal outcomes

OBJECTIVE

Evaluate the impact of pregnancy physiology and medication non-adherence on serum hydroxychloroquine (HCQ) pharmacokinetics (PK) and exposure-response in SLE.

METHODS

We conducted a PK analysis using data from two observational pregnancy registries. We enrolled pregnant women with SLE taking HCQ at least 3 months prior to, and throughout pregnancy, and excluded those with multiple gestations. Using the PK model, we conducted dosing simulations and imputed 0%/20%/40%/60% non-adherence to evaluate the impact of adherence versus physiological changes on HCQ concentrations. We compared the effect of pregnancy-average non-adherent concentrations (≤100 ng/mL vs >100 ng/mL) on preterm birth using adjusted logistic regression.

RESULTS

We enrolled 56 women who had 61 pregnancies. By the third trimester, mean apparent HCQ clearance increased by 59.6%. At a dosage of 400 mg/day, fully adherent patients are expected to have HCQ concentrations ≤100 ng/mL only 0.3% of the time, compared with 24.2% when 60% of doses are missed. Persistently low HCQ concentrations throughout pregnancy were associated with a significantly higher odds of preterm birth, controlling for lupus nephritis and race (OR 11.2; 95% CI 2.3 to 54.2; p=0.003).

CONCLUSIONS

We observed significant changes in HCQ PK during pregnancy, resulting in a shortening in the drug's half-life by 10 days; however, medication non-adherence had a more pronounced effect on HCQ exposure compared with physiological changes alone. Moreover, pregnant women with non-adherent HCQ concentrations had significantly higher rates of preterm birth. Accordingly, optimising adherence in pregnancy may be more clinically meaningful than adjusting HCQ dosage to account for physiological changes. PK modelling indicates that serum HCQ concentrations ≤100 ng/mL are suggestive of non-adherence regardless of trimester and may help identify pregnancies at risk for poor outcomes.

Optimizing reproductive health management in lupus and Sjogren's syndrome

PURPOSE OF REVIEW

People with childbearing capacity who are diagnosed with systemic lupus erythematosus (SLE) and Sjogren's syndrome (SS) have specific and important reproductive health considerations.

RECENT FINDINGS

Recommendations from the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR) provide rheumatologists and other clinicians with guidance for reproductive health management of patients with rheumatic diseases. Patient-centered reproductive health counseling can help clinicians to operationalize the EULAR and ACR guidelines and enhance patient care.

SUMMARY

Disease activity monitoring, risk factor stratification, and prescription of pregnancy-compatible medications during pregnancy help to anticipate complications and enhance pregnancy outcomes in SLE and SS. Assisted reproductive technologies are also safe among people with well-controlled disease. Safe and effective contraceptive methods are available for patients with SLE and SS, and pregnancy termination appears to be safe among these patients.
