Pregnancy Outcomes in Patients Treated with Upadacitinib: Analysis of Data from Clinical Trials and Postmarketing Reports.

BACKGROUND AND OBJECTIVE: Upadacitinib is indicated for diseases affecting persons of childbearing potential including rheumatoid arthritis, psoriatic arthritis, axial spondyloarthritis, atopic dermatitis, Crohn's disease, and ulcerative colitis; however, teratogenicity was observed in animal studies. Given the potential for human fetal risk, pregnancy avoidance measures were required during clinical trials. This analysis describes pregnancy outcomes in patients exposed to upadacitinib during pregnancy. METHODS: Clinical trial and postmarketing cases of in utero exposure to upadacitinib were identified in AbbVie's safety database through 25 April, 2023. Analysis of clinical trial cases and postmarketing reports are presented separately; prospective and retrospectively reported pregnancy outcomes are integrated for each. Descriptive rates are presented to summarize outcomes. RESULTS: There were 128 maternal upadacitinib-exposed pregnancies with known outcomes identified; 80 and 48 pregnancies were reported in clinical trials and the postmarketing setting, respectively. In clinical trials (mean in utero exposure of 5 weeks, 3 days), live births (54%), spontaneous abortions (24%), elective terminations (21%), and ectopic pregnancy (1%) were reported. There was one report of a congenital malformation: a 35-week infant with an atrial septal defect. In postmarketing cases, live births (46%), spontaneous abortions (38%), elective terminations (15%), and ectopic pregnancy (2%) were reported. CONCLUSIONS: As the data are limited for in utero exposure to upadacitinib, definitive conclusions cannot be drawn regarding the effect of upadacitinib on pregnancy outcomes. Rates of adverse pregnancy outcomes with upadacitinib exposure were comparable to rates observed in the general population or patients with autoimmune inflammatory diseases. To date, no apparent evidence of teratogenicity exists in the analyses of human pregnancies exposed to upadacitinib during the first trimester.

Exploring Reproductive Experiences With Women Enrolled in the International Vasculitis Pregnancy Registry.

OBJECTIVE: This study explored the reproductive journeys of women with vasculitis, including their conversations with healthcare providers, disease activity, medication changes, and delivery experiences. METHODS: Interviews were conducted with women registered in the Vasculitis Pregnancy Registry (VPREG), an online patient-reported registry of pregnant women with vasculitis. A team of physicians, patients, and qualitative researchers developed a qualitative interview guide. Participant responses were evaluated using thematic analysis. RESULTS: Eighteen patients with vasculitis who had experienced pregnancy were interviewed (10 antineutrophil cytoplasmic antibody-associated vasculitis, 4 Takayasu arteritis, 2 Behçet disease, 1 IgA vasculitis, 1 relapsing polychondritis). Thematic analysis revealed common experiences in the decision-making process during pregnancy planning, including accessing information from multiple sources, communicating with medical professionals, and changing treatment for vasculitis. Women sought information about vasculitis and pregnancy from various sources, including social media; however, opinions from their physicians and family members were most influential. Patients were more likely than providers to initiate conversations regarding family planning. Balancing differing opinions from subspecialists was challenging as many patients recalled acting as a liaison between multiple physicians during pregnancy. The need for self-advocacy was a common experience among patients. Most women had pregnancies that resulted in live births with delivery at term. CONCLUSION: When making decisions about pregnancy, women of reproductive age with vasculitis used multiple resources. Patients consistently valued their medical provider's opinion over alternative sources of information. To ensure comprehensive medical care, half of women relied on self-advocacy to coordinate communication among subspecialists. Most women had pregnancies that resulted in live births with delivery at term.

Reproductive Outcomes for Women With Vasculitis.

OBJECTIVE: There are limited data on the reproductive health of women with vasculitis. This study used a prospective, international vasculitis pregnancy registry to survey women during and after pregnancy. METHODS: The Vasculitis Pregnancy Registry (VPREG) is imbedded within the Vasculitis Patient-Powered Research Network, an international online research infrastructure. Any pregnant woman with a diagnosis of vasculitis can self-enroll. After enrollment, women are invited to complete online surveys at study entry, once per trimester, and postpartum. Descriptive statistics are reported here. RESULTS: Between 2015 and 2022, 147 women with 149 pregnancies enrolled in VPREG from 16 countries. Data on 78 pregnancies with known outcomes were included in this analysis. During pregnancy, women on average experienced low levels of pain related to vasculitis (scale 0-10, median 2 [IQR 1-5]) and preserved feelings of wellness (scale 0-10, median 3 [IQR 1-5]). Thirty-six percent of women reported their vasculitis was active during pregnancy. Of the 14 women requiring hospitalization during pregnancy outside of delivery, 4 cited active vasculitis as the indication. Most women (54/73, 74%) were prescribed medications for vasculitis during pregnancy. Seventy-six (97%) pregnancies resulted in live births, with 64% delivering vaginally and 21% experiencing a preterm delivery. CONCLUSION: These results demonstrate that most women with vasculitis can experience pregnancies that result in live births delivered at term. During pregnancy, a minority of women reported flares of vasculitis or the need for hospitalization due to vasculitis. These data are useful to rheumatologists and patients to inform and facilitate discussions about reproductive health and vasculitis.

Implementation of a Clinician-led Medication Adherence Intervention Among Patients With Systemic Lupus Erythematosus.

OBJECTIVE: Medication nonadherence in systemic lupus erythematosus (SLE) leads to poor clinical outcomes. We developed a clinician-led adherence intervention that involves reviewing real-time pharmacy refill data and using effective communication to address nonadherence. Prior pilot testing showed promising effects on medication adherence. Here, we describe further evaluation of how clinicians implemented the intervention and identify areas for improvement. METHODS: We audio recorded encounters of clinicians with patients who were nonadherent (90-day proportion of days covered [PDC] < 80% for SLE medications). We coded recordings for intervention components performed, communication quality, and time spent discussing adherence. We also conducted semistructured interviews with patients and clinicians on their experiences and suggestions for improving the intervention. We assessed change in 90-day PDC post intervention. RESULTS: We included 25 encounters with patients (median age 39, 100% female, 72% Black) delivered by 6 clinicians. Clinicians performed most intervention components consistently and exhibited excellent communication, as coded by objective coders. Adherence discussions took an average of 3.8 minutes, and 44% of patients had ≥ 20% increase in PDC post intervention. In structured interviews, many patients felt heard and valued and described being more honest about nonadherence and more motivated to take SLE medications. Patients emphasized patient-clinician communication and financial and logistical assistance as areas for improvement. Some clinicians wanted additional resources and training to improve adherence conversations. CONCLUSION: We provide further evidence to support the feasibility, acceptability, and fidelity of the adherence intervention. Future work will optimize clinician training and evaluate the intervention's effectiveness in a large, randomized trial.

The time of equipoise on the use of biological DMARDs in for inflammatory arthritis during pregnancy is finally over: a reappraisal of evidence to optimise pregnancy management.

Active inflammatory arthritis in pregnancy is associated with an increased risk of adverse pregnancy outcomes. Treatment of active inflammation and maintenance of low disease activity with medication reduces these risks. Therapeutic decisions on disease-modifying antirheumatic drugs (DMARDs) in pregnancy are complicated by safety concerns, which have led to inappropriate withdrawal of treatment and consequential harm to mother and fetus. Studies of inflammatory arthritis in pregnancy have consistently shown minimal safety concerns with the use of biological DMARDs and an increased risk of disease flare with discontinuation of biological DMARDs. It is our opinion that during pregnancy, the benefits of disease control with biological DMARDs, when required in addition to conventional synthetic DMARDs, outweigh the risks. In this Series paper, we review the reasons for reconsideration of equipoise and propose an agenda for future research to optimise the use of biological DMARDs in inflammatory arthritis during pregnancy.

Evaluating Factors Associated With Telehealth Appropriateness in Outpatient Rheumatoid Arthritis Encounters Using the Encounter Appropriateness Score for You (EASY).

OBJECTIVE: Telehealth has been proposed as a safe and effective alternative to in-person care for rheumatoid arthritis (RA). The purpose of this study was to evaluate factors associated with telehealth appropriateness in outpatient RA encounters. METHODS: A prospective cohort study (January 1, 2021, to August 31, 2021) was conducted using electronic health record data from outpatient RA encounters in a single academic rheumatology practice. Rheumatology providers rated the telehealth appropriateness of their own encounters using the Encounter Appropriateness Score for You (EASY) immediately following each encounter. Robust Poisson regression with generalized estimating equations modeling was used to evaluate the association of telehealth appropriateness with patient demographics, RA clinical characteristics, comorbid noninflammatory causes of joint pain, previous and current encounter characteristics, and provider characteristics. RESULTS: During the study period, 1823 outpatient encounters with 1177 unique patients with RA received an EASY score from 25 rheumatology providers. In the final multivariate model, factors associated with increased telehealth appropriateness included higher average provider preference for telehealth in prior encounters (relative risk [RR] 1.26, 95% CI 1.21-1.31), telehealth as the current encounter modality (RR 2.27, 95% CI 1.95-2.64), and increased patient age (RR 1.05, 95% CI 1.01-1.09). Factors associated with decreased telehealth appropriateness included moderate (RR 0.81, 95% CI 0.68-0.96) and high (RR 0.57, 95% CI 0.46-0.70) RA disease activity and if the previous encounters were conducted by telehealth (RR 0.83, 95% CI 0.73-0.95). CONCLUSION: In this study, telehealth appropriateness was most associated with provider preference, the current and previous encounter modality, and RA disease activity. Other factors like patient demographics, RA medications, and comorbid noninflammatory causes of joint pain were not associated with telehealth appropriateness.

Evaluation of Type 2 SLE symptoms in patients with a range of lupus nephritis activity.

BACKGROUND: Type 2 systemic lupus erythematosus (SLE) symptoms, including fatigue, fibromyalgia, and brain fog, contribute to poor health-related quality of life (HRQoL) in patients with lupus. To test the hypothesis that Type 1 (classical inflammatory lupus) activity is associated with Type 2 SLE activity, we characterized the features of Type 2 SLE in patients with a range of lupus nephritis (LN) activity. METHODS: This was a cross-sectional study of SLE patients [American College of Rheumatology (ACR) 1997 or Systemic Lupus International Collaborating Clinics (SLICC) 2012 classification criteria] from June 2018 to March 2020. Patients completed the Systemic Lupus Activity Questionnaire (SLAQ) and the Polysymptomatic Distress Scale. Patients were divided into groups based on their renal status. Active nephritis was defined using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) lupus nephritis parameter. Differences across groups were analyzed by Fisher's exact test and ANOVA. RESULTS: In this cohort of 244 patients (93% female, mean age 43 years, 58% Black), 10% had active nephritis, 35% had historical nephritis, and 55% never had nephritis (non-nephritis). Active nephritis and non-nephritis patients had a similar burden of Type 2 SLE symptoms, despite a difference in Type 1 SLE activity. Patients with active nephritis had higher Type 2 PGA (Physician Global Assessment) scores and reported more Type 2 SLE symptoms than inactive nephritis patients. Patients with inactive nephritis had the lowest Type 2 SLE activity. CONCLUSIONS: While Type 2 SLE symptoms are common in SLE, our findings suggest that patients with active nephritis experience significant Type 2 SLE symptoms that may be ameliorated as nephritis improves. We also observed that non-nephritis patients had a similar burden of Type 2 SLE symptoms as patients with active nephritis, despite having on average lower Type 1 SLE activity. Therefore, the etiology of Type 2 SLE symptoms is likely multifactorial and may be driven by inflammatory and non-inflammatory biopsychosocial factors. Key Points • Patients with active nephritis experienced significant Type 2 symptoms that may be ameliorated as nephritis improves. • Non-nephritis patients had a similar burden of Type 2 SLE symptoms as patients with active nephritis, despite having on average lower Type 1 SLE activity. • Because etiology of Type 2 SLE symptoms is likely multifactorial and may be driven by inflammatory and non-inflammatory biopsychosocial factors.

Mycophenolate mofetil withdrawal in patients with systemic lupus erythematosus: a multicentre, open-label, randomised controlled trial.

BACKGROUND: Mycophenolate mofetil is an immunosuppressant commonly used to treat systemic lupus erythematosus (SLE) and lupus nephritis. It is a known teratogen associated with significant toxicities, including an increased risk of infections and malignancies. Mycophenolate mofetil withdrawal is desirable once disease quiescence is reached, but the timing of when to do so and whether it provides a benefit has not been well-studied. We aimed to determine the effects of mycophenolate mofetil withdrawal on the risk of clinically significant disease reactivation in patients with quiescent SLE on long-term mycophenolate mofetil therapy. METHODS: This multicenter, open-label, randomised trial was conducted in 19 centres in the USA. Eligible patients were aged between 18 and 70 years old, met the American College of Rheumatology (ACR) 1997 SLE criteria, and had a clinical SLEDAI score of less than 4 at screening. Mycophenolate mofetil therapy was required to be stable or decreasing for 2 years or more if initiated for renal indications, or for 1 year or more for non-renal indications. Participants were randomly allocated in a 1:1 ratio to a withdrawal group, who tapered off mycophenolate mofetil over 12 weeks, or a maintenance group who maintained their baseline dose (1-3g per day) for 60 weeks. Adaptive random allocation ensured groups were balanced for study site, renal versus non-renal disease, and baseline mycophenolate mofetil dose (≥2 g per day vs <2 g per day). Clinically significant disease reactivation by week 60 following random allocation, requiring increased doses or new immunosuppressive therapy was the primary endpoint, in the modified intention-to-treat population (all randomly allocated participants who began study-provided mycophenolate mofetil). Non-inferiority was evaluated using an estimation-based approach. The trial was registered at ClinicalTrials.gov (NCT01946880) and is completed. FINDINGS: Between Nov 6, 2013, and April 27, 2018, 123 participants were screened, of whom 102 were randomly allocated to the maintenance group (n=50) or the withdrawal group (n=52). Of the 100 participants included in the modified intention-to-treat analysis (49 maintenance, 51 withdrawal), 84 (84%) were women, 16 (16%) were men, 40 (40%) were White, 41 (41%) were Black, and 76 (76%) had a history of lupus nephritis. The average age was 42 (SD 12·7). By week 60, nine (18%) of 51 participants in the withdrawal group had clinically significant disease reactivation, compared to five (10%) of 49 participants in the maintenance group. The risk of clinically significant disease reactivation was 11% (95% CI 5-24) in the maintenance group and 18% (10-32) in the withdrawal group. The estimated increase in the risk of clinically significant disease reactivation with mycophenolate mofetil withdrawal was 7% (one-sided upper 85% confidence limit 15%). Similar rates of adverse events were observed in the maintenance group (45 [90%] of 50 participants) and the withdrawal group (46 [88%] of 52 participants). Infections were more frequent in the mycophenolate mofetil maintenance group (32 [64%]) compared with the withdrawal group (24 [46%]). INTERPRETATIONS: Mycophenolate mofetil withdrawal is not significantly inferior to mycophenolate mofetil maintenance. Estimates for the rates of disease reactivation and increases in risk with withdrawal can assist clinicians in making informed decisions on withdrawing mycophenolate mofetil in patients with stable SLE.

Evaluating Provider Perceptions of Telehealth Utility in Outpatient Rheumatology Telehealth Encounters.

OBJECTIVE: This study aims to explore the factors associated with rheumatology providers' perceptions of telehealth utility in real-world telehealth encounters. METHODS: From September 14, 2020 to January 31, 2021, 6 providers at an academic medical center rated their telehealth visits according to perceived utility in making treatment decisions using the following Telehealth Utility Score (TUS) (1 = very low utility to 5 = very high utility). Modified Poisson regression models were used to assess the association between TUS scores and encounter diagnoses, disease activity measures, and immunomodulatory therapy changes during the encounter. RESULTS: A total of 481 telehealth encounters were examined, of which 191 (39.7%) were rated as "low telehealth utility" (TUS 1-3) and 290 (60.3%) were rated as "high telehealth utility" (TUS 4-5). Encounters with a diagnosis of inflammatory arthritis were significantly less likely to be rated as high telehealth utility (adjusted relative risk [aRR], 0.8061; p = 0.004), especially in those with a concurrent noninflammatory musculoskeletal diagnosis (aRR, 0.54; p = 0.006). Other factors significantly associated with low telehealth utility included higher disease activity according to current and prior RAPID3 scores (aRR, 0.87 and aRR, 0.89, respectively; p < 0.001) and provider global scores (aRR, 0.83; p < 0.001), as well as an increase in immunomodulatory therapy (aRR, 0.70; p = 0.015). CONCLUSIONS: Provider perceptions of telehealth utility in real-world encounters are significantly associated with patient diagnoses, current and prior disease activity, and the need for changes in immunomodulatory therapy. These findings inform efforts to optimize the appropriate utilization of telehealth in rheumatology.

Implications of the accuracy of diagnostic algorithms for systemic lupus on our understanding of racial disparities in pregnancy outcomes.

OBJECTIVE: Disparities in pregnancy outcomes among women with SLE remain understudied, with few available racially diverse datasets. We sought to identify disparities between Black and White women in pregnancy outcomes within academic institutions in the United States. METHODS: Using the Common Data Model electronic medical record (EMR)-based datasets within the Carolinas Collaborative, we identified women with pregnancy delivery data (2014-2019) and ≥1 SLE International Classification of Diseases 9 or 10 code (ICD9/10) code. From this dataset, we identified four cohorts of SLE pregnancies, three based on EMR-based algorithms and one confirmed with chart review. We compared the pregnancy outcomes identified in each of these cohorts for Black and White women. RESULTS: Of 172 pregnancies in women with ≥1 SLE ICD9/10 code, 49% had confirmed SLE. Adverse pregnancy outcomes occurred in 40% of pregnancies in women with ≥1 ICD9/10 SLE code and 52% of pregnancies with confirmed SLE. SLE was frequently over-diagnosed in women who were White, resulting in 40-75% lower rates of adverse pregnancy outcomes in EMR-derived vs confirmed SLE cohorts. Over-diagnosis was less common for Black women with pregnancy outcomes 12-20% lower in EMR-derived vs confirmed SLE cohorts. Black women had higher rates of adverse pregnancy outcomes than White women in the EMR-derived, but not the confirmed cohorts. CONCLUSION: EMR-derived cohorts of pregnancies in women who are Black, but not White, provided accurate estimations of pregnancy outcomes. The data from the confirmed SLE pregnancies suggest that all women with SLE, regardless of race, referred to academic centres remain at very high risk for adverse pregnancy outcome.

Patient and Physician Perspectives of Systemic Lupus Erythematosus Flare: A Qualitative Study.

OBJECTIVE: Systemic lupus erythematosus (SLE) flares are associated with increased damage and decreased health-related quality of life. We hypothesized that there is discordance between physicians' and patients' views of SLE flare. In this study, we aimed to explore patient and physician descriptions of SLE flares. METHODS: We conducted a qualitative descriptive study using in-depth interviews with a purposeful sample of patients with SLE (who met 1997 American College of Rheumatology or Systemic Lupus International Collaborating Clinics criteria) and practicing rheumatologists. Interviews were audio-recorded, transcribed, and analyzed using applied thematic analysis. RESULTS: Forty-two patient participants with SLE, representing a range of SLE activity, completed interviews. The majority described flare symptoms as joint pain, fatigue, and skin issues lasting several days. Few included objective signs or laboratory measures, when available, as features of flare. We interviewed 13 rheumatologists from 10 academic and 3 community settings. The majority defined flare as increased or worsening SLE disease activity, with slightly more than half requiring objective findings. Around half of the rheumatologists included fatigue, pain, or other patient-reported symptoms. CONCLUSION: Patients and physicians described flare differently. Participants with SLE perceived flares as several days of fatigue, pain, and skin issues. Providers defined flares as periods of increased clinical SLE activity. Our findings suggest the current definition of flare may be insufficient to integrate both perceptions. Further study is needed to understand the pathophysiology of patient flares and the best way to incorporate patients' perspectives into clinical assessments.

Development and psychometric evaluation of a physician global assessment for type 2 systemic lupus erythematosus symptoms.

OBJECTIVE: Manifestations of SLE can be categorised as type 1 (classic signs and symptoms of SLE) or type 2 (fatigue, widespread pain and brain fog with an unclear relationship to inflammation). While measures of type 1 SLE activity exist, most current physician-reported measures do not encompass type 2 SLE manifestations. To better evaluate type 2 SLE symptoms, we developed and psychometrically evaluated a physician-reported measure of type 2 symptoms, the Type 2 Physician Global Assessment ('Type 2 PGA'). METHODS AND ANALYSIS: The Type 2 PGA was developed and evaluated by six rheumatologists practising in the same academic lupus clinic. The study began with a roundtable discussion to establish consensus guidelines for scoring the Type 2 PGA. Following the roundtable, the Type 2 PGA was psychometrically evaluated using data prospectively collected from 263 patients with SLE enrolled in the Duke Lupus Registry. RESULTS: There was strong intra-rater and inter-rater reliability (intraclass correlation coefficient=0.83), indicating the Type 2 PGA scores were consistent within a rheumatologist and across rheumatologists. The Type 2 PGA was correlated with patient-reported symptoms of polysymptomatic distress (r=0.76), fatigue (r=0.68), cognitive dysfunction (r=0.63), waking unrefreshed (r=0.62) and forgetfulness (r=0.60), and weakly correlated with the Type 1 PGA and the Systemic Lupus Erythematosus Disease Activity Index. CONCLUSION: The Type 2 PGA performed well as a physician-reported measure of type 2 SLE symptoms. The incorporation of the Type 2 PGA into a routine rheumatology visit may improve patient care by bringing the provider's attention to certain symptoms not well represented in conventional measures of disease activity.

Using PROMIS-29 to determine symptom burdens in the context of the Type 1 and 2 systemic lupus erythematosus (SLE) model: a cross sectional study.

OBJECTIVE: To account for heterogeneity in systemic lupus erythematosus (SLE) and bridge discrepancies between patient- and physician-perceived SLE activity, we developed the Type 1 and 2 SLE model. We examined PROMIS-29 scores, a composite patient-reported outcome (PRO) measure, through the lens of the model. METHODS: Patients completed PROMIS-29 and the polysymptomatic distress scale (PSD). Rheumatologists completed the SLE disease activity index (SLEDAI), and physician's global assessments (PGAs) for Type 1 and 2 SLE. We defined Type 1 SLE using SLEDAI, Type 1 PGA, and active nephritis, and Type 2 SLE using PSD and Type 2 PGA. We compared PROMIS-29 T-scores among Type 1 and 2 SLE groups and explored whether PROMIS-29 can predict Type 1 and 2 SLE activity. RESULTS: Compared to the general population, patients with isolated Type 1 SLE reported greater pain and physical dysfunction but less depression and improved social functions; patients with high Type 2 SLE (irrespective of Type 1 activity) reported high levels of pain, fatigue, and social and physical limitations. Patients with minimal Type 1 and 2 SLE had less depression and greater physical functioning with other domains similar to national norms. PROMIS-29 predicted Type 2 but not Type 1 SLE activity. CONCLUSION: PROMIS-29 similarities in patients with high Type 2 SLE, with and without active Type 1 SLE, demonstrate the challenges of using PROs to assess SLE inflammation. In conjunction with the Type 1 and 2 SLE model, however, PROMIS-29 identified distinct symptom patterns, suggesting that the model may help clinicians interpret PROs.

Bringing Reproductive Health Guidelines Into Fellowship Training: A National Survey of Adult and Pediatric Rheumatology Fellows and Program Directors.

OBJECTIVE: This study seeks to assess rheumatology fellows' (RFs') and program directors' (PDs') interests in different educational tools and methods and to facilitate curriculum development for reproductive health related to rheumatic disease. METHODS: Constructs were conceptualized in four dimensions: 1) RF and PD confidence in their current curriculum relating to the American College of Rheumatology (ACR) Reproductive Health Guidelines (RHGs), 2) personal interest in this topic, 3) opinions of the importance of this topic, and 4) interest in a range of learning materials and educational experiences. The final survey was distributed to 753 RFs and 179 PDs in the United States using the ACR Committee on Training and Workforce email list. RESULTS: Response rates were 13% (n = 98) for RFs and 25% (n = 44) for PDs. Both groups indicated more interest in the topic than confidence in their curriculum and rated summary sheets, question banks, didactics, and online modules higher than nine other educational tools or methods. Despite interest in the topic, 38% of RF respondents and 24% of PD respondents were unaware of the recently published ACR RHGs. CONCLUSION: RFs and PDs consider reproductive health very important and report high personal interest in this topic. In contrast, both groups indicated lower confidence in current curricula, and substantial proportions of both groups were unaware of recently published guidelines. RFs' and PDs' interests in specific educational modalities are aligned. Curriculum development efforts should prioritize summary sheets, question banks, didactics, and online modules. Efforts are needed to address the educational needs of practicing rheumatologists and other professionals caring for patients with rheumatic disease.

Vasculitis and Pregnancy: Disease State and Management.

Family planning in women with vasculitis requires an interdisciplinary approach. This article summarizes recommendations and guidance for each phase of family planning in persons with vasculitis including preconception counseling, birth control, pregnancy, and breastfeeding. Pregnancy complications are presented by category of vasculitis with accompanying diagnostic and therapeutic recommendations. Birth control and assisted reproductive technology options are reviewed with special considerations for women who are high risk or have a history of blood clots. This article can be used as a clinical reference for reproductive discussions in all patients with vasculitis.

Using pooled electronic health records data to conduct pharmacoepidemiology safety studies: Challenges and lessons learned.

PURPOSE: We assessed the suitability of pooled electronic health record (EHR) data from clinical research networks (CRNs) of the patient-centered outcomes research network to conduct studies of the association between tumor necrosis factor inhibitors (TNFi) and infections. METHODS: EHR data from patients with one of seven autoimmune diseases were obtained from three CRNs and pooled. Person-level linkage of CRN data and Centers for Medicare and Medicaid Services (CMS) fee-for-service claims data was performed where possible. Using filled prescriptions from CMS claims data as the gold standard, we assessed the misclassification of EHR-based new (incident) user definitions. Among new users of TNFi, we assessed subsequent rates of hospitalized infection in EHR and CMS data. RESULTS: The study included 45 483 new users of TNFi, of whom 1416 were successfully linked to their CMS claims. Overall, 44% of new EHR TNFi prescriptions were not associated with medication claims. Our most specific new user definition had a misclassification rate of 3.5%-16.4% for prevalent use, depending on the medication. Greater than 80% of CRN prescriptions had either zero refills or missing refill data. Compared to using EHR data alone, there was a 2- to 8-fold increase in hospitalized infection rates when CMS claims data were added to the analysis. CONCLUSIONS: EHR data substantially misclassified TNFi exposure and underestimated the incidence of hospitalized infections compared to claims data. EHR-based new user definitions were reasonably accurate. Overall, using CRN data for pharmacoepidemiology studies is challenging, especially for biologics, and would benefit from supplementation by other sources.

Hospital Admissions and Mortality in Patients With Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis.

BACKGROUND/OBJECTIVES: Anti-neutrophil cytoplasmic antibody-associated vasculitis has reported hospital mortality rates ranging between 10% and 20% with inadequate information regarding causes and outcomes of these hospitalizations. Characterization of outcomes in anti-neutrophil cytoplasmic antibody-associated vasculitis can improve patient care and prognostication following hospitalization. METHODS: A medical records review of all hospitalizations between October 1, 2015, and December 31, 2018, of adults with granulomatosis with polyangiitis or microscopic polyangiitis at a single academic medical center was performed. Chart review confirmed diagnoses in patients identified by International Classification of Diseases, Tenth Revision code. Vasculitis activity was determined based on clinical data and treatment during the hospitalization. Differences in outcome measures were analyzed using Fisher exact test, t test, and Wilcoxon signed-rank test. RESULTS: Of the 127 hospitalizations among 54 patients, active vasculitis was identified in 43 hospitalizations (33.9%). A total of 15 patients with active disease, including 10 patients with a new diagnosis, required intensive care unit (ICU)-level care. Of 84 hospitalizations when vasculitis was inactive, infection was diagnosed in 31 admissions (36.9%), with inactive disease representing 44% of all ICU admissions. Overall mortality was 7% for hospitalized patients and 15% for those admitted to the ICU. An additional 5 patients died within 28 days of discharge, for an overall mortality rate of 17%. All 4 hospital deaths and 3 of 5 postdischarge deaths were in the setting of known infection. CONCLUSION: Most hospitalizations and patient deaths were in the context of inactive vasculitis, with infection being the most common cause. Infection and ICU admission were associated with patient death.
