Objectives To identify associations between mortality in cSLE patients and their characteristics: clinical and laboratory features, disease activity and damage scores, and treatment; to evaluate risk factors associated with mortality in cSLE; and to determine the most frequent causes of death in this group of patients. Methods We performed a multicenter retrospective cohort using data from 1,528 cSLE patients followed in 27 pediatric rheumatology tertiary centers in Brazil. Patients’ medical records were reviewed according to a standardized protocol, in which information regarding demographic and clinical features, disease activity and damage scores, and treatment were collected and compared between deceased cSLE patients and survivors. Univariate and multivariate analyses by Cox regression model were used to calculate risk factors for mortality, whereas survival rates were analyzed by Kaplan–Meier plots. Results A total of 63/1,528 (4.1%) patients deceased, 53/63 were female (84.1%), median age at death was 11.9 (9.4–13.1) years and median time interval between cSLE diagnosis and death was 3.2 (0.5–5.3) years. Sepsis was the main cause of death in 27/63 (42.8%) patients, followed by opportunistic infections in 7/63 (11.1%), and alveolar hemorrhage in 6/63 (9.5%) patients. The regression models resulted in neuropsychiatric lupus (NP-SLE) (HR = 2.56, 95% CI = 1.48–4.42) and chronic kidney disease (CKD) (HR = 4.33, 95% CI = 2.33–4.72), as risk factors significantly associated with mortality. Overall patient survival after cSLE diagnosis at 5, 10, and 15 years were 97%, 95.4%, and 93.8%, respectively. Conclusions This study confirmed that the recent mortality rate in cSLE in Brazil is low, but still of concern. NP-SLE and CKD were the main risk factors for mortality, indicating that the magnitude of these manifestations was significantly high.

Lupus nephritis (LN) is a frequent manifestation of childhood-onset systemic lupus erythematosus (cSLE) with a potential risk for kidney failure and poor outcomes. This study aimed to evaluate stages III, IV, and V of chronic kidney disease (CKD) and investigate risk factors for CKD in cSLE patients.We performed a nationwide observational cohort study in 27 pediatric rheumatology centers, including medical charts of 1528 cSLE patients. Data were collected at cSLE diagnosis, during follow-up, and at last visit or death, between September 2016 and May 2019.Of 1077 patients with LN, 59 (5.4%) presented with CKD, 36/59 (61%) needed dialysis, and 7/59 (11.8%) were submitted for kidney transplantation. After Bonferroni's correction for multiple comparisons (p 0.0013), determinants associated with CKD were higher age at last visit, urinary biomarker abnormalities, neuropsychiatric involvement, higher scores of disease activity at last visit and damage index, and more frequent use of methylprednisolone, cyclosporine, cyclophosphamide, and rituximab. In the regression model analysis, arterial hypertension (HR = 15.42, 95% CI = 6.12-38.83, p ≤ 0.001) and biopsy-proven proliferative nephritis (HR = 2.83, 95%CI = 1.70-4.72, p ≤ 0.001) increased the risk of CKD, while children using antimalarials had 71.0% lower CKD risk ((1.00-0.29) × 100%) than children not using them. The Kaplan-Meier comparison showed lower survival in cSLE patients with biopsy-proven proliferative nephritis (p = 0.02) and CKD (p ≤ 0.001).A small number of patients manifested CKD; however, frequencies of dialysis and kidney transplantation were relevant. This study reveals that patients with cSLE with hypertension, proliferative nephritis, and absence of use of antimalarials exhibited higher hazard rates of progression to CKD.

BACKGROUND AND OBJECTIVES: Juvenile idiopathic arthritis (JIA) is a chronic rheumatic disease which may persist into adulthood. Pain and joint deformities affect quality of life (QoL). The objective was to study the influence of JIA in QoL of children and adults, comparing the two groups. METHODS: Cross-sectional study of 47 JIA patients (20 children and 27 adults) using the following questionnaires: Juvenile Arthritis Multidimensional Assessment Report (JAMAR), Health Assessment Questionnaire (HAQ) in adults and Childhood Health Assessment Questionnaire CHAQ) in children. Epidemiological, clinical and treatment data was collected. RESULTS: No differences were found in gender, arthritis subset, presence of uveitis and fever, visual analog scale for pain and duration of morning stiffness. Adult patients required more biologics in the treatment (p=0.02) and had higher age at disease onset than children (p=0.001). About 45% of children and 51.8% of adults complained having pain and 40% of children and 48% of adults were not satisfied with the current status of their disease. CONCLUSION: Children and adult patients with JIA had similar degree of pain, morning stiffness and functional impairment. Functional impairment was considered mild but the level of pain found was higher than in other studies. Almost half of patients were not satisfied with the treatment.

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.

Background To our knowledge the influence of ethnic background in childhood-onset SLE (cSLE) presentation was not evaluated in a large population of Latin American country. Objectives To assess demographic data, clinical manifestations, laboratory abnormalities and disease activity score in cSLE patients according to ethnic groups at diagnosis Methods This multicenter study included cSLE patients(ACR 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 Results According to ethnic groups, 1,537 cSLE patients were classified in: Caucasian (n=786), African-Latin American(n=526), Asian(n=8) and others/unknown(n=217). Comparisons between 1,312 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 Conclusion Our study demonstrated that disease presentation severity of African-Latin American cSLE patients is comparable to 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. Disclosure of Interests None declared

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.

OBJETIVO: Avaliar o estresse psicológico do cuidador do paciente pediátrico com artrite idiopática juvenil (AIJ). MÉTODOS: Estudo observacional analítico transversal não controlado de 40 cuidadores de pacientes com AIJ, que foram avaliados pelo questionário Caregiver Burden Scale. Esta escala analisa cinco domínios do estresse: tensão geral, isolamento, decepção, envolvimento emocional e estresse causado por barreiras impostas pelo meio ambiente, graduando-os de 1 a 4. Os dados obtidos foram submetidos a análise estatística. RESULTADOS: Os cuidadores de pacientes com AIJ são principalmente do sexo feminino (87,5%), casados (92,1%) e com parentesco direto com o paciente (90%). O grau de estresse é maior nos cuidadores de pacientes com AIJ forma poliarticular (p = 0,006), nos solteiros (p = 0,019) e naqueles do sexo feminino (p = 0,017). A dimensão analisada na qual se observou maior nível de estresse foi a de dificuldades relacionadas com o meio ambiente. CONCLUSÃO: Mulheres casadas e com parentesco direto com o paciente são os maiores cuidadores do paciente de AIJ. Cuidado com pacientes de forma poliarticular causa mais estresse do que o de pacientes de forma oligoarticular. Barreiras impostas pelo meio ambiente são responsáveis pelo maior índice de estresse nestes cuidadores. OBJECTIVE: To assess psychological stress in primary caregivers of juvenile idiopathic arthritis (JIA) pediatric patients. METHODS: Uncontrolled cross-sectional analytical study of 40 caregivers of JIA patients. Caregivers were evaluated using the Caregiver Burden Scale, which analyzes five domains of stress on a scale of 1 to 4: general strain, isolation, disappointment, emotional involvement and strain caused by environmental barriers. The data were subjected to statistical analysis. RESULTS: Caregivers of JIA patients were mainly female (87.5%), married (92.1%) and close relatives (90%). Stress levels were higher in caregivers of polyarticular JIA patients (p = 0.006), single caregivers (p = 0.019) and female caregivers (p = 0.017). Environment-related difficulties were reported as the most stressful category by caregivers. CONCLUSION: Caregivers of JIA patients are usually married female relatives. Caring for polyarticular JIA patients is more stressful than caring for oligoarticular JIA patients. Strain caused by environmental barriers accounts for the highest levels of stress among the caregivers included in this study.
