No. of bitstreams: 0 Previous issue date: 2021-01-01 Objective: To evaluate if the 2019-European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) criteria at diagnosis of childhood-onset systemic lupus erythematosus (cSLE) are associated with higher rates of early damage scored by Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (SDI). Methods: This retrospective multicenter study included 670 cSLE patients with ≤5 years of disease duration. All patients fulfilled both 2019-EULAR/ACR and 1997-ACR classification criteria. Total score of 2019-EULAR/ACR criteria and each of its specific domains were assessed at diagnosis as predictors of damage accrual at the last visit, according to the presence of any organ damage (defined by SDI ≥ 1). Results: Median disease duration was 2.8 (IQR 1.8–3.8) years and 200 (29.9%) patients had at least one organ damage (SDI ≥ 1). The most frequent domains were neuropsychiatric (12%), renal (7%), and musculoskeletal (6%). There was a higher frequency of renal (58% vs 43%, p = 0.0004) and neuropsychiatric domain (21% vs 7%, p < 0.0001) of 2019-EULAR/ACR criteria in patients with damage (SDI ≥ 1) compared to those without damage (SDI = 0). Patients scoring renal or neuropsychiatric domains of the 2019-EULAR/ACR criteria at diagnosis were associated with renal damage (odds ratio 9.701, 95% confidence interval 3.773–24.941, p < 0.001) or neuropsychiatric damage (OR 9.480, 95% CI 5.481–16.399, p25 was associated with more overall (SDI ≥ 1) (38% vs 25%, p = 0.0002) and renal damage (11% vs 5%, p = 0.023). Conclusions: The 2019-EULAR/ACR criteria at diagnosis were associated with a higher rate of early damage in cSLE patients, especially for renal and neuropsychiatric damage. Of note, damage was particularly associated with high disease activity at diagnosis and 2019-EULAR/ACR score >25.

Made available in DSpace on 2021-06-25T12:24:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-11-11 Background: Concerns about the safety and efficacy of vaccines in patients with autoimmune diseases (AID) have led to contradictions and low vaccination coverage in this population, who are at a higher risk of infections, including by human papillomavirus (HPV). Although HPV vaccines have been recommended for immunocompromised patients, there is still a lack of data to support its use for AID patients, such as juvenile dermatomyositis (JDM) patients. The aim of this study was to assess the safety and immunogenicity of the quadrivalent HPV (qHPV) vaccine in a cohort of JDM patients. Methods: JDM patients aged from 9 to 20 years and healthy controls (HC) were enrolled to receive a 3-dose schedule of qHPV vaccine from March/2014 to March/2016. Study visits were performed before the first dose, 1 month after the second and third doses, and 6 months after the third dose. Participants completed a diary of possible adverse events for 14 days following each dose of vaccination (AEFV). Disease activity and current therapy were analyzed at each visit for JDM patients. In addition, serum samples from all participants were collected to test antibody concentrations against HPV16 and 18 at each visit. Participant recruitment was conducted in ten Brazilian centres. From 47 eligible JDM patients and 41 HC, 42 and 35, respectively, completed the 3-dose schedule of the vaccine, given that five JDM patients and two HC had received doses prior to their inclusion in the study. Results: The AEFVs presented by the participants were mild and in general did not differ between JDM and HC groups. No severe AEFVs were related to the vaccination. Disease activity was stable, or even improved during the follow-up. One month after the third dose of the vaccine the JDM group presented seropositivity of 100% for HPV16 and 97% for HPV18, similarly to the HC group, who presented 100% for both serotypes (p = 1.000). Six months after the third dose the seropositivity for the patient group was 94% for both HPV types. Conclusions: The HPV vaccination in this cohort of JDM patients was safe and immunogenic. Since the seropositivity against HPV16 and 18 was very high after the 3-dose schedule, this regimen should be recommended for JDM patients.

To assess childhood-onset systemic lupus erythematosus-related antiphospholipid syndrome(cSLE-APS) in a large Brazilian population.A retrospective observational cohort study was carried-out in 27 Pediatric Rheumatology university centers, including 1519 cSLE patients.cSLE-APS was observed in 67/1519 (4%) and was diagnosed at disease onset in 39/67 (58%). The median disease duration was 4.9 (0-17) years. Thrombosis recurrences were evidenced in 18/67 (27%) cSLE-APS patients. The most frequent thrombosis sites in cSLE-APS patients were: venous thrombosis in 40/67 (60%), especially deep vein thrombosis in 29/40 (72%); arterial thrombosis in 35/67 (52%), particularly stroke; small vessels thrombosis in 9/67 (13%) and mixed thrombosis in 3/67 (4%). Pregnancy morbidity was observed in 1/67 (1%). Non-thrombotic manifestation associated to cSLE-APS occurred in 21/67 (31%), mainly livedo reticularis in 14/67 (21%), valvar thickening in 4/67 (6%) and valvar vegetations not related to infections in 2/67 (3%). None of them had catastrophic APS. Further analysis demonstrated that the median of SLICC/ACR-DI [1(0-5) vs. 0(0-7),p 0.0001] was significantly higher in cSLE-APS patients compared to cSLE without APS. The frequencies of cerebrovascular disease (40% vs. 1%,p 0.0001), polyneuropathy (9% vs. 1%,p 0.0001), SLICC/ACR-DI ≥1 (57% vs. 27%, p 0.0001) and intravenous cyclophosphamide use (59% vs. 37%, p 0.0001) were significantly higher in the former group.Our large multicenter study demonstrated that cSLE-APS was a rare condition, occurring during disease course with a high accrual damage. Central and peripheral neuropsychiatric involvements were distinctive features of this autoimmune thrombosis.

No. of bitstreams: 0 Previous issue date: 2019-01-01 Objective: To evaluate the influence of ethnicity in presentation of childhood-onset systemic lupus erythematosus (cSLE) patients. Methods: This multicenter study included cSLE patients (American College of Rheumatology criteria) followed in 27 Pediatric Rheumatology services of Brazil. Ethnicities were classified in four groups according to the parents’ and all four grandparents’ self-reported ethnicity. The statistical analysis was performed using the Bonferroni’s correction (p < 0.0027). Results: According to ethnic groups, 1537 cSLE patients were classified in Caucasian (n = 786), African-Latin American (n = 526), Asian (n = 8), and others/unknown (n = 217). Comparisons between 1312 African-Latin American and Caucasian revealed similar median age at cSLE diagnosis [12.2(2.6–18) vs. 12.1(0.3–18) years, p = 0.234], time interval to diagnosis [0.25(0–12) vs. 0.3(0–10) years, p = 0.034], and SLEDAI-2K score [14(0–55) vs. 14(0–63), p = 0.781] in both groups. The mean number of diagnostic criteria according to SLICC (6.47 ± 1.911 vs. 5.81 ± 1.631, p < 0.0001) and frequencies of maculopapular lupus rash (8% vs. 3%, p < 0.0001), palate oral ulcers (17% vs. 11%, p = 0.001), tongue oral ulcers (4% vs. 1%, p = 0.001), and nonscarring alopecia (29% vs. 16%, p < 0.0001) were significantly higher in African-Latin American, whereas malar rash (45% vs. 58%, p < 0.0001) was more frequent in Caucasian. The presence of anti-phospholipid antibody (23% vs. 12%, p < 0.0001), low complement levels (58% vs. 41%, p < 0.0001), and isolated direct Coombs test (10% vs. 5%, p = 0.001) was also significantly higher in the former group. Conclusions: Our study demonstrated that disease presentation severity of African-Latin American cSLE patients is comparable with Caucasian. Mucocutaneous manifestations and autoantibodies profile were the only distinctive features of the former group. The unique mixed background of Brazilian patients probably minimized race diversity spectrum of these patients.Key Points• Our study demonstrated that disease presentation severity of African-Latin American cSLE patients is comparable with Caucasian.• Mucocutaneous manifestations and autoantibodies profile were the only distinctive features of African-Latin American cSLE patients.• African-Latin American cSLE patients had more often anti-phospholipid antibodies and hypocomplementemia.• The unique mixed background of Brazilian patients probably minimized race diversity spectrum of these patients.

No. of bitstreams: 0 Previous issue date: 2018-09-01 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Objective: The objective of this study was to compare demographic data, clinical/laboratorial features and disease activity at diagnosis in three different groups with distinct time intervals between onset of signs/symptoms and disease diagnosis. Methods: A multicenter study was performed in 1555 childhood-onset systemic lupus erythematosus (American College of Rheumatology criteria) patients from 27 pediatric rheumatology services. Patients were divided into three childhood-onset systemic lupus erythematosus groups: A: short time interval to diagnosis (500 mg/day (48% vs. 45% vs. 36%, P = 0.002) and low complement levels (81% vs. 81% vs. 71%, P < 0.0001) compared with groups A or B. Conclusions: Our large Brazilian multicenter study demonstrated that for most childhood-onset systemic lupus erythematosus patients, diagnosis is delayed probably due to mild disease onset. Conversely, the minority has a very short time interval to diagnosis and a presentation with a more severe and active multisystemic condition.
