RESUMO

OBJECTIVE: Hydroxychloroquine (HCQ) and chloroquine (CQ) are key drugs in systemic lupus (SLE) and related diseases. Retinal toxicity remains the most concerning complication. We studied factors potentially associated with retinal toxicity, using case-control analyses. METHODS: Within our lupus clinic cohort, we identified patients with retinal changes using the SLICC Damage Index. We confirmed HCQ/CQ retinopathy with chart review, and selected up to three SLE controls for each case, matched on age at SLE diagnosis and SLE duration. RESULTS: Over an average 12.8 years of follow-up, within 326 patients exposed to antimalarial drugs, 18(5.5%) developed retinal toxicity. The minimum number of years of HCQ/CQ exposure before retinopathy developed was 8 years (maximum 33 years). Mean HCQ/CQ duration was similar in cases (18.5 years, 95% CI 15.2, 21.7) and controls (16.7 years, 95% CI 14.3, 19.0) likely due to our matching on SLE duration. Versus controls, cases tended to have more renal disease (cases 22.2%, controls 14.8%) and were slightly less likely to be Caucasian (cases 61.1%, controls 74.1%), but neither variables reached statistical significance. Among patients with retinal toxicity, the number previously exposed to CQ was more than three times that in controls. CONCLUSION: Just over 5% of patients developed anti-malarial retinal complications, over an average of 12.8 years. No cases were detected in the first 5 years of therapy. Past CQ use was more common in cases versus controls. Future studies using larger cohorts are underway to better define the roles of therapy duration, race/ethnicity, and other factors.

RESUMO

Objectives: Chronic rheumatic diseases can challenge social and family relationships. We compared marital status in patients with systemic lupus erythematous (SLE) with their general population counterparts, stratified by sex and age of SLE onset. Methods: We performed a cross-sectional analysis of a cohort of 382 patients with SLE at our centre (349 females, 33 males). We determined how many were married or living common-law at the time of last study visit. Patients were then divided into: SLE diagnosis before 18, between 18 and 30, between 31 and 44 and after 45 years of age. We then compared marital status among male and female patients with SLE, to Quebec age-specific marital statistics. Results: Of 382 patients with SLE, 202 (52.9%) were married or living common-law, which was 9% lower than general population rates (95% CI 2% to 16%). One-third of women with paediatric-onset SLE were married or living common-law, which was 28% lower than their general population counterparts (95% CI 6% to 46%). Half of women diagnosed between age 18 and 30 were married or living common law, which was 14% less than general population rates (95% CI 4% to 25%). We could not establish significant differences for women diagnosed after age 30, or for males, versus their general population counterparts. Conclusions: Women diagnosed with SLE before age 30 were less likely to be married/living common-law, versus general population rates. This was not apparent for those diagnosed later in life. We did not clearly establish this effect in males, possibly due to power issues (vs a true effect of sex/gender). Additional studies (eg, focus groups) could elucidate reasons for our findings.

RESUMO

OBJECTIVES: To assess the prevalence of combined hormonal contraceptives (CHCs) in reproductive-age women with SLE with and without possible contraindications and to determine factors associated with their use in the presence of possible contraindications. METHODS: This observational cohort study included premenopausal women ages 18-45 years enrolled in the SLICC Registry ⩽15 months after SLE onset, with annual assessments spanning 2000-2017. World Health Organization Category 3 or 4 contraindications to CHCs (e.g. hypertension, aPL) were assessed at each study visit. High disease activity (SLEDAI score >12 or use of >0.5 mg/kg/day of prednisone) was considered a relative contraindication. RESULTS: A total of 927 SLE women contributed 6315 visits, of which 3811 (60%) occurred in the presence of one or more possible contraindication to CHCs. Women used CHCs during 512 (8%) visits, of which 281 (55%) took place in the setting of one or more possible contraindication. The most frequently observed contraindications were aPL (52%), hypertension (34%) and migraine with aura (22%). Women with one or more contraindication were slightly less likely to be taking CHCs [7% of visits (95% CI 7, 8)] than women with no contraindications [9% (95% CI 8, 10)]. CONCLUSION: CHC use was low compared with general population estimates (>35%) and more than half of CHC users had at least one possible contraindication. Many yet unmeasured factors, including patient preferences, may have contributed to these observations. Further work should also aim to clarify outcomes associated with this exposure.

RESUMO

OBJECTIVE: To determine whether offspring from mothers with systemic lupus erythematosus (SLE), exposed in utero to antimalarials, have an increased risk of ocular anomalies during childhood versus unexposed SLE offspring. METHODS: We systematically performed searches of PubMed, Embase, and Web of Science databases for original human data on fetal and/or child ocular outcomes following exposure to antimalarials during pregnancy and/or lactation, from their inception until March 2017. RESULTS: A total of 10 cohort studies and 2 randomized controlled trials, ranging in size from 6 to 444 exposed infants studied, and 3 case reports met the inclusion criteria for our systematic review. Collectively, 1,477 infants were studied, 789 of which were exposed to hydroxychloroquine or chloroquine. In all, 563 exposed infants had follow-up visits after delivery (ranging from <3 months to 19 years), and 331 of these exposed infants underwent ophthalmologic examinations during the follow-up period. Our review of the literature suggests a low-to-nonexistent risk of visual abnormalities in offspring exposed to antimalarials. CONCLUSION: In children exposed to appropriate doses of antimalarials antenatally, the risk of ocular toxicity appears low to nonexistent. The potential benefits and risks of antimalarials should be discussed in all SLE pregnancies, and high dosages should continue to be avoided.

RESUMO

OBJECTIVE: To evaluate the risk of serious infections in rheumatoid arthritis (RA) offspring exposed to tumor necrosis factor inhibitors (TNFi) in the gestational period compared to unexposed RA offspring, as well as to children from the general population. METHODS: We used US claim data (2011-2015) to identify 2,989 offspring born to women who have RA and a randomly selected group of 14,596 control children, matched ≥4:1 for maternal age, year of delivery, and state of residence. We defined TNFi exposure based on ≥1 filled prescription during pregnancy. We ascertained serious infections based on ≥1 hospitalization, with infection as a primary diagnosis, at ≤12 months of life. We performed multivariable analyses, adjusting for maternal demographics, comorbidities, pregnancy complications, and drugs. RESULTS: Among RA offspring, 380 (12.7%) were exposed to TNFi during pregnancy. The percentage of serious infections in RA offspring with no TNFi exposure (2.0%; 95% confidence interval [95% CI] 1.5, 2.6) was similar to that in non-RA offspring (1.9%; 95% CI 1.9, 2.2), while the percentage of serious infections in RA offspring with TNFi exposure was 3.2% (95% CI 1.5, 5.6). In multivariable analyses, we were unable to establish an increased risk of serious infections in RA offspring exposed to TNFi versus both non-RA offspring (odds ratio [OR] 1.7, 95% CI 0.8, 3.7) and RA offspring unexposed to TNFi (OR 1.4, 95% CI 0.7, 2.8). CONCLUSION: We did not demonstrate a marked excess risk for serious infections in RA offspring exposed to TNFi during pregnancy versus unexposed RA offspring or general population controls.

RESUMO

OBJECTIVE: Several autoimmune diseases have familial aggregation and, possibly, common genetic predispositions. In a large population-based study, we evaluated whether children born to mothers with systemic lupus erythematosus (SLE) have an increased risk of rheumatic and nonrheumatic autoimmune diseases versus children born to mothers without SLE. METHODS: Using the Offspring of SLE Mothers Registry, we identified children born live to SLE mothers and their matched controls, and ascertained autoimmune diseases based on ≥1 hospitalization or ≥2 physician visits with a relevant diagnostic code. We adjusted for maternal age, education, race/ethnicity, obstetric complications, calendar birth year, and sex of child. RESULTS: A total of 509 women with SLE had 719 children, while 5,824 matched controls had 8,493 children. The mean ± SD follow-up period was 9.1 ± 5.8 years. Children born to mothers with SLE had a similar frequency of rheumatic autoimmune diagnoses (0.14%; 95% confidence interval [95% CI] 0.01-0.90) versus controls (0.19% [95% CI 0.11-0.32]). There was a trend toward more nonrheumatic autoimmune diseases in SLE offspring (1.11% [95% CI 0.52-2.27]) versus controls (0.48% [95% CI 0.35-0.66]). In multivariate analyses, we did not see a clear increase in rheumatic autoimmune disease (odds ratio [OR] 0.71 [95% CI 0.11-4.82]), but children born to mothers with SLE had a substantially increased risk of nonrheumatic autoimmune disease versus controls (OR 2.30 [95% CI 1.06-5.03]). CONCLUSION: Although the vast majority of offspring have no autoimmune disease, children born to women with SLE may have an increased risk of nonrheumatic autoimmune diseases versus controls. Additional studies assessing offspring through to adulthood would be additionally enlightening.

RESUMO

OBJECTIVE: Limited evidence suggests a potentially increased risk of allergic conditions in offspring born to women with systemic lupus erythematosus (SLE). In a large population-based study, we aimed to determine if children born to mothers with SLE have an increased risk of allergic conditions compared to children born to mothers without SLE. METHODS: Using the Offspring of SLE Mothers Registry, we identified children born live to mothers with SLE and their matched controls, and ascertained the number of allergic conditions (asthma, allergic rhinitis, eczema, urticaria, angioedema, and anaphylaxis) based on ≥1 hospitalization or ≥1 or 2 physician(s) visit(s) with a relevant diagnostic code. We adjusted for maternal age, education, race/ethnicity, obstetrics complications, calendar year of birth, sex of the child, and maternal medication. RESULTS: There were 509 women with SLE who had 719 children, while 5,824 matched controls had 8,493 children. The mean ± SD followup period was 9.1 ± 5.8 years. Compared to controls, more children born to mothers with SLE had evidence of allergic conditions (43.9% [95% confidence interval (95% CI) 40.4-47.6] versus 38.1% [95% CI 37.0-39.1]). In multivariate analysis (n = 9,212), children born to mothers with SLE had an increased risk of allergic conditions versus control children (odds ratio 1.35 [95% CI 1.13-1.61]). CONCLUSION: Compared to children from the general population, children born to women with SLE may have an increased risk of allergic conditions. Genetics, shared environmental exposures, as well as in utero exposure to maternal autoantibodies and cytokines may mediate this increased risk.

RESUMO

OBJECTIVES: To compare physical and mental health-related quality of life (HRQoL) across four systemic autoimmune rheumatic diseases (SARD). METHODS: Incident subjects enrolled in four SARD cohorts, namely systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA) and idiopathic inflammatory myopathies (IIM) were studied. The outcomes of interest were baseline Short Form Health Survey physical (PCS) and mental (MCS) component summary scores. Multivariate analysis was conducted to determine whether PCS and MCS scores differed across SARD type. RESULTS: The study included 118 SLE (93% women, mean age 36 years), 108 SSc (79% women, mean age 55), 64 RA (63% women, mean age 58) and 25 IIM (68% women, mean age 49) subjects. Mean PCS scores were 38.9 ± 12.2 in SLE, 37.1 ± 13.3 in RA, 35.0 ± 13.6 in SSc and 28.0 ± 15.4 in IIM. Mean MCS scores were 45.0 ± 13.3 in RA, 44.4 ± 14.7 in SSc, 40.1 ± 14.3 in SLE and 33.6 ± 18.7 in IIM. SARD type was an independent predictor of HRQoL with, in some cases, the magnitude of the differences reaching one standard deviation (IIM worse PCS scores compared to SLE (ß -12.23 [95% CI -18.11, -6.36; p<0.001]); IIM worse MCS scores compared to SSc (ß -11.05 [95% CI -17.53, -4.58; p = 0.001]) and RA (ß -11.72 [95% CI -18.62, -4.81; p = 0.001]). CONCLUSIONS: Cross-SARD research provides a novel approach to gain greater understanding of commonalities and differences across rheumatic diseases. The differences observed warrant further research into correlates and trajectories over time.

RESUMO

OBJECTIVE: To estimate the incidence rate of clinically apparent arterial thrombotic events and associated comorbidities in patients with primary systemic vasculitis. METHODS: Using large cohort administrative data from Quebec, Canada, we identified patients with vasculitis, including polyarteritis nodosa (PAN) and granulomatosis with polyangiitis (GPA). Incident acute myocardial infarctions (AMIs) and cerebrovascular accidents (CVAs) after the diagnosis of vasculitis were ascertained in the PAN and GPA group via billing and hospitalization data. These were compared to rates of a general population comparator group. The incidences of comorbidities (type 2 diabetes mellitus, dyslipidemia, and hypertension) were also collected. RESULTS: Among the 626 patients identified with vasculitis, 19.7% had PAN, 2.9% had Kawasaki disease, 23.8% had GPA, 52.4% had GCA, and 1.3% had Takayasu arteritis. The AMI rate was substantially higher in males aged 18-44 with PAN, with rates up to 268.1 events per 10,000 patient years [95% CI 67.1-1070.2], approximately 30 times that in the age- and sex-matched control group. The CVA rate was also substantially higher, particularly in adults aged 45-65. Patients with vasculitis had elevated incidences of diabetes, dyslipidemia, and hypertension versus the general population. CONCLUSION: Atherothrombotic rates were elevated in patients identified as having primary systemic vasculitis. While incident rates of cardiovascular comorbidities were also increased, the substantial elevation in AMIs seen in young adults suggests a disease-specific component which requires further investigation.

RESUMO

To describe the characteristics of patients receiving belimumab, overall patterns of systemic lupus erythematosus (SLE) care, clinical outcomes, and changes in glucocorticoid dose following 6 months of therapy with belimumab, and healthcare resource utilization in belimumab users in Canadian clinical practice settings. Retrospective multicenter medical chart review study of adult patients with SLE who were prescribed belimumab as part of usual care and who received ≥8 infusions or 6 months of treatment. Primary endpoints included physician-determined overall clinical improvement from baseline, glucocorticoid use, and physician-determined SLE disease severity at Month 6. In total, 52 patients were included in the study. At belimumab initiation, 5.8/76.9/17.3% of patients had mild/moderate/severe SLE, respectively. Oral glucocorticoids were discontinued in 11.4% of patients and 59.1% received a lower dose at Month 6. At Month 6, 80.8/57.7/17.3% of patients had a physician-determined clinical improvement of ≥20/≥50/≥80%, respectively. Sixteen patients had a SLE Disease Activity Index-2K score at both baseline and Month 6, with a mean improvement of 2.6 ± 5.3 from 8.1 ± 3.2 at baseline. No formal disease assessment tool was utilized for 42.3% of study patients at baseline. This study provides the first real-world insights into belimumab use in Canada. It demonstrates significant reduction or discontinuation of glucocorticoid dose in 70.5% of patients and clinically significant improvement following 6 months' belimumab therapy. The high number of patients with no formal disease activity assessments highlights a key care gap in SLE treatment in the real-world setting.

RESUMO

OBJECTIVE: There is recent evidence to suggest that in utero exposure to maternal antibodies and cytokines is an important risk factor for autism spectrum disorders (ASDs). We aimed to systematically review the risk of ASDs in children born to mothers with rheumatoid arthritis (RA) compared to children born to mothers without RA. METHODS: We conducted a systematic review of original articles using the electronic databases PubMed, Embase, and Web of Science. RESULTS: Our literature search yielded a total of 70 articles. Of the potentially relevant studies retrieved, 67 were excluded for lack of relevance and/or because they did not report original data. Three studies were included in the final analysis. A case-control study found no difference in the prevalence of RA in mothers of children with ASDs versus control mothers. Another case-control study showed a statistically significant 8-fold increase in autoimmune disorders, including RA, in mothers of offspring with ASDs compared to controls. Forty-six percent of offspring with ASDs had a first-degree relative with RA, compared to 26% of controls. And in a population-based cohort study, investigators observed an increased risk of ASDs in children with a maternal history of RA compared to children born to unaffected mothers. These studies had methodologic limitations: none controlled for medication exposures, only 1 controlled for obstetric complications and considered the timing of RA diagnosis in relation to pregnancy, and all but 1 used a case-control study design. CONCLUSION: Observational studies suggest a potentially increased risk of ASDs in children born to mothers with RA compared to children born to mothers without RA, although data are limited.

RESUMO

BACKGROUND: Systemic Lupus Erythematosus (SLE) is a serious, complex, and chronic illness. Similar to most other chronic illness states, there is great interest in helping persons with SLE engage in their disease management. OBJECTIVE: The objectives of this study were to (1) develop the Lupus Interactive Navigator (LIN), a web-based self-management program for persons with SLE, and (2) test the LIN for usability and acceptability. METHODS: The LIN development platform was based on the results of preliminary comprehensive needs assessments and adapted from the Oncology Interactive Navigator, a web-based tool developed for persons with cancer. Medical researchers, writers, designers, and programmers worked with clinical experts and persons with SLE to develop content for the LIN. Usability and acceptability of the LIN was tested on individuals with SLE meeting American College of Rheumatology criteria, who were recruited from five Canadian SLE clinics. Participants were provided with access to the LIN and were asked to use it over a two-week period. Following the testing period, participants were contacted for a 30-minute telephone interview to assess usability and acceptability. RESULTS: The content for the LIN was subdivided into six primary information topics with interview videos featuring rheumatologists, allied health professionals, and persons with SLE. Usability and acceptability of the LIN was tested on 43 females with SLE. Of these, 37 (86%) completed telephone interviews. The average age was 43.6 (SD 15.9) years and disease duration averaged 14.1 (SD 10.8) years. Median time spent on LIN was 16.3 (interquartile range [IQR]:13.7, 53.5) minutes and median number of sessions was 2 (IQR: 1, 3). Overall, Likert ratings (0=strongly disagree; 7=strongly agree) of website usability and content were very high, with 75% scoring >6 out of 7 on all items. All participants agreed that LIN was easy to use, would recommend it to others with SLE, and would refer to it for future questions about SLE. Very high ratings were also given to relevancy, credibility, and usefulness of the information provided. Overall, 73% of the participants rated all topics helpful to very helpful. Participants who reported more prior knowledge about SLE rated items regarding improvement in knowledge and helpfulness relatively lower than persons with less prior knowledge. Most participants commented that the LIN would be very useful to those newly diagnosed with SLE. Minor revisions were recommended. CONCLUSIONS: This study furthers the understanding of the needs in the SLE community and delivers a unique eHealth tool to promote self-management in persons with SLE. The LIN was found to be highly acceptable in content and usability. The information provided on LIN may be most helpful for individuals with less experience with the disease, such as those newly diagnosed, indicating the need to tailor the content for persons with more SLE experience.

RESUMO

OBJECTIVE: There are few precise or recent estimates of the risk or causes of stillbirths in women with systemic lupus erythematosus (SLE). Thus, we undertook the present study to examine causes of stillbirths in mothers with SLE versus those without SLE. METHODS: The Offspring of SLE Mothers Registry (OSLER) is a large population-based cohort, identified through Quebec's health care databases (1989-2009), including all women who had ≥1 hospitalization for delivery after SLE diagnosis, and a randomly selected control group of women matched for age and year of delivery. We identified stillbirths and ascertained the cause of death as indicated on death certificates. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated, and multivariate logistic regression analysis was performed to estimate the risk of stillbirth in women with SLE versus controls. RESULTS: In our cohort, 509 women with SLE had 729 births, including 9 stillbirths, while 5,829 matched controls had 8,541 births, including 47 stillbirths. We observed more stillbirths in mothers with SLE than in controls (1.24% versus 0.55%, difference 0.69% [95% CI 0.03, 1.88]). Women with SLE had an increased risk of stillbirth compared to controls (adjusted OR 2.13 [95% CI 1.02, 4.45]). We also observed a trend toward more stillbirths due to placenta-mediated pregnancy complications in mothers with SLE than in controls (44% [95% CI 14, 79] versus 15% [95% CI 6, 28]). CONCLUSION: Compared to women from the general population, women with SLE have an increased risk of stillbirth. Stillbirths in women with SLE might be more often caused by placenta-mediated pregnancy complications compared to stillbirths in mothers without SLE.

RESUMO

OBJECTIVE: The Canadian Vasculitis research network (CanVasc) is composed of physicians from different medical specialties and researchers with expertise in vasculitis. One of its aims is to develop recommendations for the diagnosis and management of antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV) in Canada. METHODS: Diagnostic and therapeutic questions were developed based on the results of a national needs assessment survey. A systematic review of existing non-Canadian recommendations and guidelines for the diagnosis and management of AAV and studies of AAV published after the 2009 European League Against Rheumatism/European Vasculitis Society recommendations (publication date: January 2009) until November 2014 was performed in the Medline database, Cochrane library, and main vasculitis conference proceedings. Quality of supporting evidence for each therapeutic recommendation was graded. The full working group as well as additional reviewers, including patients, reviewed the developed therapeutic recommendations and nontherapeutic statements using a modified 2-step Delphi technique and through discussion to reach consensus. RESULTS: Nineteen recommendations and 17 statements addressing general AAV diagnosis and management were developed, as well as appendices for practical use, for rheumatologists, nephrologists, respirologists, general internists, and all other healthcare professionals more occasionally involved in the management of patients with AAV in community and academic practice settings. CONCLUSION: These recommendations were developed based on a synthesis of existing international guidelines, other published supporting evidence, and expert consensus considering the Canadian healthcare context, with the intention of promoting best practices and improving healthcare delivery for patients with AAV.

RESUMO

OBJECTIVE: In utero exposure to maternal antibodies and cytokines are potential risk factors for autism spectrum disorders (ASDs). The aim of this study was to determine whether children born to mothers with systemic lupus erythematosus (SLE) have an increased risk of ASD compared to children born to mothers without SLE. METHODS: The study population was derived from the Offspring of SLE Mothers Registry (OSLER), a large population-based cohort identified through healthcare databases in Quebec (1989-2009) comprising all women who had ≥1 hospitalization for a delivery (stillbirth or live birth) after SLE diagnosis. As general population controls, a randomly selected group of women without SLE was matched ≥4:1 to the mothers with SLE for age and year of delivery. Children born live to mothers with SLE and those born live to matched controls were identified, and a recorded diagnosis of ASD was ascertained for each child. Multivariate analyses were performed to adjust for parents' demographic characteristics, sex, birth order of the child, maternal comorbidities, and obstetric complications. RESULTS: In total, 509 women with SLE had 719 children, and 5,824 matched controls had 8,493 children. Children born to women with SLE were more frequently found to have a diagnosis of ASD compared to controls (frequency of recorded ASDs 1.4% [95% confidence interval (95% CI) 0.8-2.5] versus 0.6% [95% CI 0.5-0.8]), a difference of 0.8% (95% CI 0.1-1.9). The mean age at ASD diagnosis was younger in offspring of SLE mothers (mean 3.8 years, 95% CI 1.8-5.8) compared to offspring of controls (mean 5.7 years, 95% CI 4.9-6.5). In primary multivariate analysis, SLE offspring had a substantially increased risk of ASD compared to controls (odds ratio 2.19, 95% CI 1.09-4.39). CONCLUSION: Compared to children from the general population, children born to women with SLE have an increased risk of ASD, although, in absolute terms, it represents a rare outcome. These hypothesis-generating data provide direction for additional studies of maternal autoimmunity and ASD risk.

RESUMO

OBJECTIVE: Humor has neurophysiological effects influencing the release of cortisol, which may have a direct impact on the immune system. Laughter is associated with a decreased production of inflammatory cytokines both in the general population and in rheumatoid arthritis (RA). Our objective was to explore the effects of humor on serum cytokines [particularly interleukin-6 (IL-6)] and cortisol levels in systemic lupus erythematosus (SLE), after a standard intervention (120 min of visual comedy). MATERIAL AND METHODS: We enrolled 58 females with SLE from consecutive patients assessed in the Montreal General Hospital lupus clinic. The subjects who consented to participate were randomized in a 1:1 ratio to the intervention (watching 120 min of comedy) or control group (watching a 120 min documentary). Measurements of cytokine and serum cortisol levels as well as 24-h urine cortisol were taken before, during, and after the interventions. We compared serum cytokine levels and serum and 24-h urine cortisol levels in the humor and control groups and performed regression analyses of these outcomes, adjusting for demographics and the current use of prednisone. RESULTS: There were no significant differences between the control and humor groups in demographics or clinical variables. Baseline serum levels of IL-6, IL-10, tumor necrosis factor-alpha, and B-cell activating factor were also similar in both groups. There was no evidence of a humor effect in terms of decreasing cytokine levels, although there was some suggestion of lowered cortisol secretion in the humor group based the 24-h urinary cortisol levels in a subgroup. CONCLUSION: In contrast to what has been published for RA, we saw no clear effects of humor in altering cytokine levels in SLE, although interesting trends were seen for lower cortisol levels after humor intervention compared with the control group.

RESUMO

BACKGROUND: In a large population-based study, we aimed to determine whether children born to women with systemic lupus erythematosus (SLE) have an increased risk of congenital heart defects (CHDs) in comparison with children born to women without SLE. METHODS AND RESULTS: The Offspring of SLE Mothers Registry (OSLER) includes all women who had ≥1 hospitalization for delivery after SLE diagnosis, identified through Quebec's healthcare databases (1989-2009), and a randomly selected control group of women, matched ≥4:1 for age and year of delivery. We identified children born live to SLE mothers and their matched controls, and ascertained CHD based on ≥1 hospitalization or physician visit with relevant diagnostic codes, within the first 12 months of life. We performed multivariable logistic regression analyses, using the generalized estimating equation method, to adjust for relevant covariates. Five hundred nine women with SLE had 719 children, whereas 5824 matched controls had 8493 children. In comparison with controls, children born to women with SLE experienced more CHD (5.2% [95% confidence interval (CI), 3.7-7.1] versus 1.9% [95% CI, 1.6-2.2], difference 3.3% [95% CI, 1.9-5.2]). In multivariable analyses, children born to women with SLE had a substantially increased risk of CHD (odds ratio, 2.62; 95% CI, 1.77-3.88) in comparison with controls. In addition, in comparison with controls, offspring of SLE mothers had a substantially increased risk of having a CHD repair procedure (odds ratio, 5.82; 95% CI, 1.77-19.09). CONCLUSIONS: In comparison with children from the general population, children born to women with SLE have an increased risk of CHD, and an increased risk of having a CHD repair procedure, as well.

RESUMO

OBJECTIVE: To estimate the early prevalence of various electrocardiographic (EKG) abnormalities in patients with systemic lupus erythematosus (SLE) and to evaluate possible associations between repolarization changes (increased corrected QT [QTc] and QT dispersion [QTd]) and clinical and laboratory variables, including the anti-Ro/SSA level and specificity (52 or 60 kd). METHODS: We studied adult SLE patients from 19 centers participating in the Systemic Lupus International Collaborating Clinics (SLICC) Inception Registry. Demographics, disease activity (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K]), disease damage (SLICC/American College of Rheumatology Damage Index [SDI]), and laboratory data from the baseline or first followup visit were assessed. Multivariate logistic and linear regression models were used to asses for any cross-sectional associations between anti-Ro/SSA and EKG repolarization abnormalities. RESULTS: For the 779 patients included, mean ± SD age was 35.2 ± 13.8 years, 88.4% were women, and mean ± SD disease duration was 10.5 ± 14.5 months. Mean ± SD SLEDAI-2K score was 5.4 ± 5.6 and mean ± SD SDI score was 0.5 ± 1.0. EKG abnormalities were frequent and included nonspecific ST-T changes (30.9%), possible left ventricular hypertrophy (5.4%), and supraventricular arrhythmias (1.3%). A QTc ≥440 msec was found in 15.3%, while a QTc ≥460 msec was found in 5.3%. Mean ± SD QTd was 34.2 ± 14.7 msec and QTd ≥40 msec was frequent (38.1%). Neither the specificity nor the level of anti-Ro/SSA was associated with QTc duration or QTd, although confidence intervals were wide. Total SDI was significantly associated with a QTc interval exceeding 440 msec (odds ratio 1.38 [95% confidence interval 1.06, 1.79]). CONCLUSION: A substantial proportion of patients with recent-onset SLE exhibited repolarization abnormalities, although severe abnormalities were rare.
