Serious Infections in Offspring Exposed in Utero to Vedolizumab.

Controlling IBD during pregnancy is important for maternal and fetal outcomes. We created a cohort of children born to mothers with IBD, comparing the risk of infections in those exposed to vedolizumab vs unexposed. We detected no increased risk.

N-Terminal pro-Brain Natriuretic Peptide is a biomarker for cardiovascular damage in systemic lupus erythematous: a cross-sectional study.

OBJECTIVES: Prediction models based on traditional risk factors underestimate cardiovascular (CV) risk in systemic lupus erythematosus (SLE). In a large sample of unselected SLE patients, we investigated cross-sectional associations of NT-proBNP with cardiovascular damage (CVD). METHODS: Serum NT-proBNP was measured in SLE patients enrolled in the MUHC Lupus Clinic registry. Serum were collected between March 2022 and April 2023 at annual research visits. The primary outcome was CVD identified on the SLICC Damage Index. Factors associated with CVD and NT-proBNP levels were determined. RESULTS: Overall, 270 SLE patients (female 91%, median age 50.7 [1st quartile- 3rd quartile : 39.6-62.1] years) were analyzed for the primary outcome. Among them, 33 (12%) had CVD. The ROC curve for NT-proBNP demonstrated strong associations with CVD (AUC 0.78, 95% CI 0.69-0.87) with a threshold of 133 pg/ml providing the best discrimination for those with/without CVD. Hypertension (OR 3.3, 95% CI 1.2-9.0), dyslipidaemia (OR 3.6, 95% CI 1.3-9.6) and NT-proBNP > 133 pg/ml (OR 7.0, 95% CI, 2.6-19.1) were associated with CVD in the multivariable logistic regression model. Increased NT-proBNP levels were associated with age (OR 4.2, 95% CI 2.2-8.3), ever smoking (OR 1.9, 95% CI 1.0-3.5), reduced eGFR (4.1, 95% CI 1.3-13.1), prior pericarditis/pleuritis (OR 2.5, 95% CI 1.4-4.5) and aPL antibodies (OR 2.6, 95% CI 1.4-4.9). CONCLUSION: NT-proBNP is a biomarker for CV damage in SLE. The novel associations of NT-proBNP levels with prior pericarditis/pleuritis and aPL antibodies suggest new avenues for research to better understand what drives CV risk in SLE.

Assessing Serious Infections in Children Exposed In Utero to Ustekinumab.

Chronic inflammatory conditions, including inflammatory bowel disease (IBD), psoriasis (PsO), and psoriatic arthritis (PsA), have a high burden among women of reproductive age. There has been significant interest in finding safe ways of controlling disease activity during pregnancy without adversely affecting the pregnancy or offspring.

Trimethoprim-sulfamethoxazole prophylaxis during treatment of granulomatosis with polyangiitis with rituximab in the United States of America: a retrospective cohort study.

BACKGROUND: Antibiotic prophylaxis is recommended during ANCA-associated vasculitis (AAV) induction. We aimed to describe the frequency, persistence, and factors associated with trimethoprim-sulfamethoxazole (TMP-SMX) use in an adult population sample with granulomatosis with polyangiitis (GPA) treated with rituximab (RTX). METHODS: We identified adults with GPA treated with RTX within the Merative™ Marketscan® Research Databases (2011-2020). TMP-SMX prophylaxis was defined as a [Formula: see text] 28-day prescription dispensed within a month of starting RTX. We estimated TMP-SMX persistence, allowing prescription refill gaps of 30 days. Multivariable logistic regression and Cox proportional hazards regression assessed the factors associated with baseline TMP-SMX use and persistence, respectively. Covariates included age, sex, calendar year, insurance type, immunosuppressant use, hospitalization, and co-morbidities. RESULTS: Among 1877 RTX-treated GPA patients, the mean age was 50.9, and 54% were female. A minority (n = 426, 23%) received TMP-SMX with a median persistence of 141 (IQR 83-248) days. In multivariable analyses, prophylaxis was associated with prednisone use in the month prior to RTX ([Formula: see text] 20 mg/day vs none, OR 3.96; 95% CI 3.0-5.2; 1-19 mg/day vs none, OR 2.63; 95% CI 1.8-3.8), and methotrexate use (OR 1.48, 95% CI 1.04-2.1), intensive care (OR 1.95; 95% CI 1.4-2.7), and non-intensive care hospitalization (OR 1.56; 95% CI 1.2-2.1) in the 6 months prior to RTX. Female sex (OR 0.63; 95% CI 0.5-0.8) was negatively associated with TMP-SMX use. CONCLUSIONS: TMP-SMX was dispensed to a minority of RTX-treated GPA patients, more often to those on glucocorticoids and with recent hospitalization. Further research is needed to determine the optimal use and duration of TMP-SMX prophylaxis following RTX in AAV.

Outcomes associated with antiphospholipid antibodies in COVID-19: A prospective cohort study.

Background: The significance of antiphospholipid antibodies (aPL) in COVID-19 remains uncertain. Objectives: We determined whether aPL are associated with COVID-19 and/or thrombosis or adverse outcomes during hospitalization for COVID-19. Methods: Symptomatic adults tested for SARS-CoV-2 for clinical reasons (March-July 2020) with either ≥1 positive polymerase chain reaction (COVID-19+) or all negative (non-COVID-19) results were recruited to a biobank collecting plasma, clinical data, and outcomes. We tested baseline plasma samples (days 0-7) of all subjects (and day-30 samples in the COVID-19+ subjects, when available) for aPL (anticardiolipin immunoglobulin [Ig]M/IgG, anti-ß2-glycoprotein I IgM/IgG, antiphosphatidylserine/prothrombin IgM/IgG, and lupus anticoagulant). We compared the baseline prevalence of aPL between the COVID-19+ and non-COVID-19 subjects. Among hospitalized COVID-19+ subjects, multivariable logistic regression was used to evaluate the association of aPL (and their subtypes) with arterial or venous thromboembolic events, acute kidney injury, intensive care unit admission, mechanical ventilation, and death after adjusting for potential confounders. Results: At baseline, 123 of 289 (43%) COVID+ subjects had ≥1 aPL versus 116 of 261 (32%) non-COVID-19 subjects (difference, 10%; 95% CI, 3%-18%). Among 89 COVID+ subjects with repeated samples, aPL persisted on day 30 in 15 of 34 (44%) subjects with baseline aPL positivity, and half of those without aPL at baseline developed one or more new aPL. In hospitalized COVID-19 subjects (n = 241), baseline aPL positivity was associated with acute kidney injury (odds ratio [OR], 1.8; 95% CI, 1.1-3.2) and mechanical ventilation (OR, 3.2; 95% CI, 1.5-6.8) but not death (OR, 1.2; 95% CI, 0.6-2.5). In secondary analyses, medium-to-high titers of anticardiolipin IgG (>40) were associated with thromboembolic events (OR, 7.3; 95% CI, 1.8-30.1). Conclusion: In patients with COVID-19, aPL may help identify an increased risk of thrombosis and other adverse outcomes.

Ustekinumab Safety in Pregnancy: A Comprehensive Review.

Chronic inflammatory conditions, including inflammatory bowel diseases (IBD), psoriasis, and psoriatic arthritis, are prevalent among women of reproductive age; patients with active disease during pregnancy may be at an increased risk of adverse birth outcomes. For this reason, physicians are focused on approaches to controlling disease activity prior to and during pregnancy. The safety profile of many therapies used for these conditions has been relatively well established, though evidence on newer therapies is lacking. Ustekinumab is a relatively new interleukin-12/23 inhibitor approved for IBD, psoriasis, and psoriatic arthritis, whose safety in pregnancy is not yet fully understood. In this comprehensive review, we critically assess the available evidence on ustekinumab in pregnancy across animal studies and human case reports, case series, observational studies, and clinical practice guidelines. We show that, to date, studies have not identified an excess risk of adverse pregnancy outcomes among women exposed to ustekinumab in pregnancy, with few exposed pregnancies and potential for some bias. Clinical guidelines are conflicted regarding whether they recommend continuing or discontinuing ustekinumab, highlighting the paucity of data and need for more research on this issue.

Measuring the Impact of MyLupusGuide in Canada: Results of a Randomized Controlled Study.

OBJECTIVE: This study was undertaken to assess the effects of a web-based program, MyLupusGuide, developed to facilitate self-management in systemic lupus erythematosus (SLE). METHODS: In this randomized controlled online study, participants received either immediate access to the MyLupusGuide site or delayed access starting on month 3. The primary outcome was the patient activation measure (PAM) score. Secondary outcomes included measurements of health status, self-efficacy, coping, perceived patient-physician relationship, and medication adherence. Outcomes were measured at the baseline visit and at the 3-month and 6-month follow-up visits. We used linear mixed modeling to compare PAM scores between the 2 groups at months 3 and 6. RESULTS: There were 541 participants included in this study. The mean ± SE age was 50 ± 14 years; 93% were female and 74% were White. The mean ± SE disease duration was 17 ± 12 years, and 56% visited MyLupusGuide at least once. The baseline mean ± SE PAM score was 61.2 ± 13, with 36% scoring low for perceived self-management skills. After 3 months of exposure to MyLupusGuide, there were no differences in terms of PAM scores between groups. In exploratory analyses, we found significant improvement in PAM scores in those who had low PAM scores at baseline and in male individuals. We observed significant improvements in self-efficacy before and after access to MyLupusGuide and delayed improvements at month 6 compared to month 3 in terms of mental health and emotional coping. CONCLUSION: MyLupusGuide increases self-efficacy but not patient activation. A total of 56% of participants visited the MyLupusGuide site during the study period. Individuals with lupus need support to become activated toward self-management behaviors.

Evaluating the Construct of Damage in Systemic Lupus Erythematosus.

OBJECTIVE: The Systemic Lupus International Collaborating Clinics (SLICC), American College of Rheumatology (ACR), and the Lupus Foundation of America are developing a revised systemic lupus erythematosus (SLE) damage index (the SLICC/ACR Damage Index [SDI]). Shifts in the concept of damage in SLE have occurred with new insights into disease manifestations, diagnostics, and therapy. We evaluated contemporary constructs in SLE damage to inform development of the revised SDI. METHODS: We conducted a 3-part qualitative study of international SLE experts. Facilitated small groups evaluated the construct underlying the concept of damage in SLE. A consensus meeting using nominal group technique was conducted to achieve agreement on aspects of the conceptual framework and scope of the revised damage index. The framework was finally reviewed and agreed upon by the entire group. RESULTS: Fifty participants from 13 countries were included. The 8 thematic clusters underlying the construct of SLE damage were purpose, items, weighting, reversibility, impact, time frame, attribution, and perspective. The revised SDI will be a discriminative index to measure morbidity in SLE, independent of activity or impact on the patient, and should be related to mortality. The SDI is primarily intended for research purposes and should take a life-course approach. Damage can occur before a diagnosis of SLE but should be attributable to SLE. Damage to an organ is irreversible, but the functional consequences on that organ may improve over time through physiological adaptation or treatment. CONCLUSION: We identified shifts in the paradigm of SLE damage and developed a unifying conceptual framework. These data form the groundwork for the next phases of SDI development.

More than a 'Hundred Days War': Persistent SARS-CoV-2 infection in a patient with ANCA-associated vasculitis.

BACKGROUND: Few reports exist on the characteristics and outcomes of persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in immunocompromised hosts. METHODS: A 49-year-old patient with granulomatosis with polyangiitis (GPA) and a renal transplant experienced multiple hospitalizations for coronavirus disease 2019 (COVID-19) pneumonia and relapses between October 2020 and February 2021. Careful chart review of medical history, hospitalizations, and microbiological testing including SARS-CoV-2 cycle threshold values, therapies, and imaging was undertaken. SARS-CoV-2 genome sequencing was performed in five viral samples to distinguish persistent infection from re-infection with a different strain. RESULTS: Sequencing confirmed that all samples tested were from the same viral lineage, indicating a long-term, persistent infection rather than re-infection with a new strain. The patient ultimately stabilized after two courses of remdesivir plus dexamethasone, replacement intravenous immunoglobulin, and bamlanivimab. Rituximab maintenance therapy for vasculitis remains on hold. CONCLUSIONS: SARS-CoV-2 may persist for several months in immunocompromised hosts and may go unrecognized as an ongoing active infection. More studies are needed to determine how to optimize COVID-19 treatment in this vulnerable population.

HISTORIQUE: Il existe peu de rapports sur les caractéristiques et les issues de l'infection par le coronavirus 2 du syndrome respiratoire aigu sévère (SRAS-CoV-2) chez les hôtes immunodéprimés. MÉTHODOLOGIE: UNE PATIENTE de 49 ans receveuse d'une transplantation rénale atteinte d'une granulomatose avec polyangéite a été hospitalisée à de multiples reprises à cause d'une pneumonie à maladie à coronavirus 2019 (COVID-19) et de récidives entre octobre 2020 et février 2021. Les chercheurs ont exécuté une analyse attentive du dossier pour connaître l'histoire médicale de la patiente, les hospitalisations et les tests microbiologiques effectués, y compris les valeurs seuils du cycle du SRAS-CoV-2, les traitements et les techniques d'imagerie. Ils ont procédé au séquençage du génome du SRAS-CoV-2 dans cinq prélèvements viraux pour distinguer l'infection persistante de la réinfection par une souche différente. RÉSULTATS : Le séquençage a confirmé que tous les prélèvements effectués provenaient de la même lignée virale, ce qui détermine une infection persistante prolongée plutôt qu'une réinfection par une nouvelle souche. L'état de la patiente a fini par se stabiliser après deux traitements au remdésivir combiné à de la dexaméthasone, une thérapie de substitution par immunoglobuline intraveineuse et du bamlanivimab. Un traitement d'entretien de la vasculite au rituximab demeure en suspens. CONCLUSIONS: Le SRAS-CoV-2 peut persister plusieurs mois chez les hôtes immunodéprimés, et un état d'infection active continue peut passer inaperçu. Plus d'études devront être réalisées pour déterminer le moyen d'optimiser le traitement de la COVID-19 dans cette population vulnérable.

The Impact of COVID-19 on Maternal Mental Health during Pregnancy: A Comparison between Canada and China within the CONCEPTION Cohort.

The effect of the COVID-19 pandemic on maternal mental health has been described in Canada and China but no study has compared the two countries using the same standardized and validated instruments. In this study, we aimed to evaluate and compare the impact of COVID-19 public health policies on maternal mental health between Canada and China, as we hypothesize that geographical factors and different COVID-19 policies are likely to influence maternal mental health. Pregnant persons >18 years old were recruited in Canada and China using a web-based strategy. All participants recruited between 26 June 2020 and 16 February 2021 were analyzed. Self-reported data included sociodemographic variables, COVID-19 experience and maternal mental health assessments (Edinburgh Perinatal Depression Scale (EPDS), Generalized Anxiety Disorders (GAD-7) scale, stress and satisfaction with life). Analyses were stratified by recruitment cohort, namely: Canada 1 (26 June 2020-10 October 2020), Canada 2 and China (11 October 2020-16 February 2021). Overall, 2423 participants were recruited, with 1804 participants within Canada 1, 135 within Canada 2 and 484 in China. The mean EDPS scores were 8.1 (SD, 5.1) in Canada 1, 8.1 (SD, 5.2) in Canada 2 and 7.7 (SD, 4.9) in China (p-value Canada 2/China: p = 0.005). The mean GAD-7 scores were 2.6 (SD, 2.9) in China, 4.3 (SD, 3.8) in Canada 1 (p < 0.001) and 5.8 (SD, 5.2) in Canada 2 (p < 0.001). When adjusting for stress and anxiety, being part of the Chinese cohort significantly increased the chances of having maternal depression by over threefold (adjusted OR 3.20, 95%CI 1.77-5.78). Canadian and Chinese participants reported depressive scores nearly double those of other crises and non-pandemic periods. Lockdowns and reopening periods have an important impact on levels of depression and anxiety among pregnant persons.

The Canadian Mother-Child Cohort Active Surveillance Initiative (CAMCCO): Comparisons between Quebec, Manitoba, Saskatchewan, and Alberta.

BACKGROUND: Given that pregnant women taking medications are excluded from clinical trials, real-world evidence is essential. We aimed to build a Canadian Mother-Child Cohort Active Surveillance Initiative (CAMCCO) and compare frequency of prematurity, low-birth-weight (LBW), major malformations, multiplicity, and gestational medication use across four provinces. METHODS: CAMCCO is a collaborative research infrastructure that uses real-world data from large provincial health care databases in Canada; developed with standardized methods to similarly construct population-based pregnancy/child cohorts with longitudinal follow-up by linking administrative/hospital/birth databases. CAMCCO also includes a common repository to i) share algorithms and case definitions based on diagnostic and procedural codes for research/training purpose, and ii) download aggregate data relevant to primary care providers, researchers, and decision makers. For this study, data from Quebec (1998-2015), Manitoba (1995-2019), Saskatchewan (1996-2020), and Alberta (2005-2018) are compared (Chi-square tests, p-values), and trends are calculated using Cochran-Armitage trend tests. RESULTS: Almost two-thirds (61%) of women took medications during pregnancy, mostly antibiotics (26%), asthma drugs (8%), and antidepressants (4%). Differences in the prevalence of prematurity (5.9-6.8%), LBW (4.0-5.2%), and multiplicity (1.0-2.5%) were statistically significant between provinces (p<0.001). Frequency of major malformations increased over time in Quebec (7-11%; p<0.001), Saskatchewan (5-11%; p<0.001), and Alberta (from 7-8%; p<0.001), and decreased in Manitoba (5-3%; p<0.001). Cardiovascular and musculoskeletal malformations were the most prevalent. INTERPRETATION: Medications are often used among Canadian pregnancies but adverse pregnancy outcomes vary across provinces. Digitized health data may help researchers and care providers understand the risk-benefit ratios related to gestational medication use, as well as province-specific trends.

The COVID-19 Pandemic Impacted Maternal Mental Health Differently Depending on Pregnancy Status and Trimester of Gestation.

Introduction: We aimed to measure the impact of the COVID-19 pandemic on maternal mental health, stratifying on pregnancy status, trimester of gestation, and pandemic period/wave. Methods: Pregnant persons and persons who delivered in Canada during the pandemic, >18 years, were recruited, and data were collected using a web-based strategy. The current analysis includes data on persons enrolled between 06/2020−08/2021. Maternal sociodemographic indicators, mental health measures (Edinburgh Perinatal Depression Scale (EPDS), Generalized Anxiety Disorders (GAD-7), stress) were self-reported. Maternal mental health in pregnant women (stratified by trimester, and pandemic period/wave at recruitment) was compared with the mental health of women who had delivered; determinants of severe depression were identified with multivariate logistic regression models. Results: 2574 persons were pregnant and 626 had already delivered at recruitment. Participants who had delivered had significantly higher mean depressive symptom scores compared to those pregnant at recruitment (9.1 (SD, 5.7) vs. 8.4 (SD, 5.3), p = 0.009). Maternal anxiety (aOR 1.51; 95%CI 1.44−1.59) and stress (aOR 1.35; 95%CI 1.24−1.48) were the most significant predictors of severe maternal depression (EDPS ˃ 13) in pregnancy. Conclusion: The COVID-19 pandemic had a significant impact on maternal depression during pregnancy and in the post-partum period. Given that gestational depression/anxiety/stress has been associated with preterm birth and childhood cognitive problems, it is essential to continue following women/children, and develop strategies to reduce COVID-19's longer-term impact.

Clinical Significance of Raynaud Phenomenon in Systemic Lupus Erythematosus.

OBJECTIVE: There are limited reports of the clinical significance of Raynaud phenomenon (RP) in systemic lupus erythematosus (SLE), with some suggesting RP is associated with less severe lupus. Since most prior studies were small and/or focused on a specific race/ethnic demographic, it is unclear if those results are generalizable. We evaluated whether RP was associated with demographic and clinical factors in a large multiethnic SLE cohort. METHODS: We studied Montreal General Hospital SLE cohort patients who are followed with standardized annual assessments. We included patients with at least 1 visit across 2011-2018 and assessed demographic and clinical variables (using the 1997 American College of Rheumatology criteria and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index) at their first visit. We present multivariate logistics regression analyses of cross-sectional associations between these variables and RP in SLE. RESULTS: Of 489 SLE patients, most were female (n = 445, 91%). Mean age at SLE diagnosis was 31.5 (standard deviation, 13.5) years, and 169 (34.6%) had RP. In our fully adjusted model, female sex (odds ratio [OR], 2.43; 95% confidence interval [CI], 1.07-6.03), White race/ethnicity (OR, 1.85; 95% CI, 1.10-3.17), neurological/neuropsychiatric manifestations (OR, 1.98; 95% CI, 1.10-3.56), and anti-RNP antibodies (OR, 3.03; 95% CI, 1.73-5.38) were positively associated with RP, whereas hemolytic anemia and cellular casts were negatively associated. CONCLUSIONS/DISCUSSION: Over one third of our large multiethnic North American SLE cohort had RP. This study confirmed associations between RP and a specific SLE phenotype.

Association between chronic obstructive pulmonary disease, smoking, and interstitial lung disease onset in rheumatoid arthritis.

OBJECTIVES: In rheumatoid arthritis (RA), respiratory manifestations include chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). We assessed whether baseline COPD and smoking were associated with RA-ILD onset. METHODS: We identified new-onset ILD in incident RA subjects within the MarketScan Commercial Claims database, using physician and/or hospitalisation diagnostic codes. Smoking data (current, past, never) were available for a subset via a health questionnaire. Kaplan-Meier analyses assessed time to ILD onset, stratified by prior COPD and smoking. Multivariate Cox regression models were adjusted for age, sex, and (in the subset) smoking. Sensitivity analyses adjusted for past RA drugs. RESULTS: Among 373,940 new RA subjects, 6343 (1.7%) developed ILD (8.1 events per 1000 person-year, 95% CI 7.9, 8.3). ILD was more common among subjects with baseline COPD. Adjusting for age and sex, the hazard ratio (HR) between baseline COPD and incident ILD was 2.15, 95% CI 1.93, 2.39. We could not establish a clear relationship between current smoking and ILD; in the subset with smoking data, the HR point estimate for COPD was similar but the 95% CI was wider (due to fewer subjects) and included the null value. Adjusting for baseline RA drugs did not change results. CONCLUSIONS: Pre-existing COPD in incident RA subjects was associated with higher risk of future ILD. While a trend persisted after adjusting for smoking, we were limited by reduced sample size. Our study highlights the importance of ongoing assessments of potentially complicated relationships between smoking, COPD, and other factors in RA-associated ILD.

Challenges of Perceived Self-Management in Lupus.

OBJECTIVE: Systemic lupus erythematosus is a chronic autoimmune disease with varied and unpredictable levels of disease activity. The ability to self-manage lupus is important in controlling disease activity. Our objective was to determine levels of patient activation toward self-management in lupus. METHODS: We used baseline results from the MyLupusGuide study, which had recruited 541 lupus patients from 10 lupus centers. We used the Patient Activation Measure (PAM), a validated self-reported tool designed to measure activation toward self-management ability, as our primary variable and examined its association with demographic, disease-related, patient-provider communication and psychosocial variables captured in our study protocol. Univariable and multivariable linear regressions were performed using linear mixed models, with a random effect for centers. RESULTS: The mean ± SD age of participants was 50 ± 14 years, 93% were female, 74% were White, and the mean ± SD disease duration was 17 ± 12 years. The mean ± SD PAM score was 61.2 ± 13.5, with 36% of participants scoring in the 2 lower levels, indicating low activation. Variables associated with low activation included being single, having lower physical health status, lower self-reported disease activity, lower self-efficacy, use of more emotional coping and fewer distraction and instrumental coping strategies, and a perceived lack of clarity in patient-doctor communication. CONCLUSION: Low patient activation was observed in more than one-third of lupus patients, indicating that a large proportion of patients perceived that they are lacking in lupus self-management skills. These results highlight a modifiable gap in perceived self-management ability among patients with lupus.

Predictors of Unsuccessful Hydroxychloroquine Tapering and Discontinuation: Can We Personalize Decision-Making in Systemic Lupus Erythematosus Treatment?

OBJECTIVE: Hydroxychloroquine (HCQ) is a key systemic lupus erythematosus (SLE) drug, making concerns of drug shortages grave. Our objective was to evaluate factors associated with poor outcomes after HCQ taper or discontinuation in SLE. METHODS: We studied 5 Canadian SLE cohorts between 1999 and 2019, following patients from the date of HCQ tapering (cohort 1) or discontinuation (cohort 2). A composite outcome was defined as any of the following: a need for therapy augmentation, an increase (of at least 4 points) in the Systemic Lupus Erythematosus Disease Activity Index 2000 score, or hospitalization for SLE. In each cohort, multivariable Cox regression was used to identify demographic and clinical factors associated with time to the earliest of these events. A third cohort continuing to receive HCQ was also studied, to assess whether the same factors influenced the outcome even when the HCQ dose was unchanged. RESULTS: The poor outcome rate, per 100 person-years, was 35.7 (95% confidence interval [95% CI] 31.6-40.3) in the HCQ taper cohort (n = 398), 29.0 (95% CI 25.5-33.0) in the discontinuation cohort (n = 395), and 16.1 (95% CI 13.2-19.6) in the maintenance cohort (n = 395). In patients tapering HCQ, baseline prednisone use was independently associated with greater risk of poor outcomes. In the discontinuation cohort, the risk of poor outcomes was greater for Black patients and those diagnosed with SLE at age ≤25 years. Among those maintaining HCQ, baseline immunosuppressive use and First Nations ethnicity were associated with poor outcomes. CONCLUSION: We identified demographic and clinical factors associated with poor outcomes after HCQ taper/discontinuation. This information is critical in the current setting of potential shortages, but over the long term, such information could inform personalized therapies.

Pregnancy Termination in Patients With Rheumatic Diseases.

Rheumatic diseases affect women during their reproductive years. Many women with rheumatic diseases become pregnant; some undergo pregnancy termination. However, there are no official guidelines on pregnancy termination in patients with rheumatic diseases. This work provides an overview of factors that health care professionals must consider. We highlight areas that require further studies and the importance of pregnancy planning and contraception counseling. Patients with rheumatic diseases need to be informed of adverse maternal and fetal outcomes of pregnancy to make informed reproductive decisions and reduce the need for pregnancy terminations.

Impact of glucocorticoids on the incidence of lupus-related major organ damage: a systematic literature review and meta-regression analysis of longitudinal observational studies.

OBJECTIVE: In systemic lupus erythematosus (SLE), disease activity and glucocorticoid (GC) exposure are known to contribute to irreversible organ damage. We aimed to examine the association between GC exposure and organ damage occurrence. METHODS: We conducted a literature search (PubMed (Medline), Embase and Cochrane January 1966-October 2021). We identified original longitudinal observational studies reporting GC exposure as the proportion of users and/or GC use with dose information as well as the occurrence of new major organ damage as defined in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. Meta-regression analyses were performed. Reviews, case-reports and studies with <5 years of follow-up, <50 patients, different outcomes and special populations were excluded. RESULTS: We selected 49 articles including 16 224 patients, 14 755 (90.9%) female with a mean age and disease duration of 35.1 years and of 37.1 months. The mean follow-up time was 104.9 months. For individual damage items, the average daily GC dose was associated with the occurrence of overall cardiovascular events and with osteoporosis with fractures. A higher average cumulative dose adjusted (or not)/number of follow-up years and a higher proportion of patients on GC were associated with the occurrence of osteonecrosis. CONCLUSIONS: We confirm associations of GC use with three specific damage items. In treating patients with SLE, our aim should be to maximise the efficacy of GC and to minimise their harms.
