Background: Childhood-onset systemic lupus erythematosus (cSLE) is a chronic autoimmune disease with the course often more severe than in adults, and the activity of the disease widely being evaluated by SLE Disease Activity Index (SLEDAI 2K) and damage by the SLICC/ACR damage index (SDI). Objectives: To explore the correlation between the SLEDAI-2K disease activity index at the time of diagnosis and the SLICC/ACR damage index of patients at their last follow up and to predict the risk of organ damage occurrence in time. Methods: The retrospective study included children treated for cSLE from January 1991 to September 2017 at Department of Pediatrics, UHC Zagreb. All children were diagnosed according to the ACR 1997 and SLICC 2012 criteria. Results: The disease development of 93 children (74 females) with cSLE was examined in this study. The median (range) follow up time was 7 (0.5–24) years and the median (range) age at diagnosis was 13 (5–19) years. Mean (SD) SLEDAI-2K was 18.3 (9.0) at the disease onset. 35 children (38 %) had organ damage at the last follow up with the median (range) SDI 0 (0–7). Th e first organ systems damaged in affected patients were renal (28%), musculoskeletal (22%), ocular (19%), neuropsychiatric (17%), cardiovascular (11%) and peripheral vascular (2.8%). A statistically signifi cant positive correlation was found between SLEDAI-2K at the disease onset and SDI (τb = 0.252, p = 0.003). No significant correlation was determined between the duration of the disease (τb = 0.042, p = 0.628) or follow up period (τb = 0.111, p = 0.191) and SDI, nor in SDI in regard to gender (p= 0.574). Using Kaplan-Meier method we estimated the decrease in ratio of patients without organ damage since diagnosis or the occurrence of the first symptoms. Since the estimated ratio of patients with organ damage at the endpoint was less than 50%, we could not estimate the time required for damage development in 50% of patients. However, we are 95% sure that the damage is not happening in the first 9 years aft er diagnosis. Conclusions: The high correlation detected between SLEDAI-2K and SDI indicated that the presentation of the cSLE at onset can be prognostic of the course and long-term prognosis of lupus. Our findings suggest that it is unlikely that organ damage will occur in 50% of patients in the first nine years of the disease course. References: 1. Gladman DD, Ibanez D, Urowitz MB.

No. of bitstreams: 0 Previous issue date: 2017-11-01 Objectives To assess clinical digital vasculitis (DV) as an initial manifestation of childhood‐onset systemic lupus erythematosus (cSLE) within a large population. Methods Multicenter cross‐sectional study including 852 cSLE patients (ACR criteria) followed in ten Pediatric Rheumatology centers in São Paulo State, Brazil. Results DV was observed in 25/852 (3%) cSLE patients. Periungual hemorrhage was diagnosed in 12 (48%), periungual infarction in 7 (28%), tip finger ulceration in 4 (16%), painful nodules in 1 (4%) and gangrene in 1 (4%). A poor outcome, with digital resorption, occurred in 5 (20%). Comparison of patients with and without DV revealed higher frequency of malar rash (80% vs. 53%, p = 0.008), discoid rash (16% vs. 4%, p = 0.017), photosensitivity (76% vs. 45%, p = 0.002) and other cutaneous vasculitides (80% vs. 19%, p < 0.0001), whereas the frequency of overall constitutional features (32% vs. 61%, p = 0.003), fever (32% vs. 56%, p = 0.020) and hepatomegaly (4% vs. 23%, p = 0.026) were lower in these patients. Frequency of female gender, severe multi‐organ involvement, autoantibodies profile and low complement were alike in both groups (p > 0.05). SLEDAI‐2 K median, DV descriptor excluded, was significantly lower in patients with DV compared to those without this manifestation [10(0‐28) vs. 14(0‐58), p = 0.004]. Visceral vasculitis or death were not observed in this cSLE cohort. The frequency of cyclophosphamide use (0% vs. 18%, p = 0.014) was significantly lower in the DV group. Conclusion Our large multicenter study identified clinical DV as one of the rare initial manifestation of active cSLE associated with a mild multisystemic disease, in spite of digital resorption in some of these patients.

No. of bitstreams: 0 Previous issue date: 2017-08-01 Objective The objective of this study was to assess outcomes of childhood systemic lupus erythematosus (cSLE) in three different age groups evaluated at last visit: group A early-onset disease ( 0.05). Mortality rate was significantly higher in group A compared to groups B and C (15% vs 10% vs 6%, p = 0.028). Out of 69 deaths, 33/69 (48%) occurred within the first two years after diagnosis. Infections accounted for 54/69 (78%) of the deaths and 38/54 (70%) had concomitant disease activity. Conclusions This large multicenter study provided evidence that early-onset cSLE group had distinct outcomes. This group was characterized by higher mortality rate and neuropsychiatric/vascular/skin organ damage in spite of comparable frequencies of severe cumulative lupus manifestations. We also identified that overall death in cSLE patients was an early event mainly attributed to infection associated with disease activity.

ResumoGengivite e periodontite são doenças periodontais imunoinflamatórias caracterizadas por infecções localizadas crônicas geralmente associadas a uma inflamação insidiosa. Essa revisão narrativa discute doenças periodontais e mecanismos que influenciam a resposta imune e a autoimunidade na área das doenças reumáticas pediátricas (DRP), particularmente a artrite idiopática juvenil (AIJ), lúpus eritematoso sistêmico juvenil (LESJ) e dermatomiosite juvenil (DMJ). Foi notada maior frequência de gengivite nessas doenças em comparação com controles sadios, enquanto casos de periodontite foram achados raros. Em pacientes com AIJ, a gengivite e a periodontite estavam relacionadas a fatores mecânicos, artrite crônica com incapacitação funcional, desregulação da resposta imunoinflamatória, dieta e medicamentos, principalmente corticosteroides e ciclosporina. Em pacientes com LESJ, a gengivite estava associada a períodos mais longos da doença, doses elevadas de corticosteroides, hiperativação dos linfócitos B e elevação da imunoglobulina G. São escassos os dados sobre doenças periodontais na população com DMJ; nos pacientes ativos, foi observado um padrão gengival singular, caracterizado por eritema gengival, dilatação dos capilares e formação arbustiforme. Em conclusão, gengivite foi a doença periodontal mais comum em pacientes com DRP. A associação observada com a atividade da doença reforça a necessidade de futuros estudos, com o intuito de determinar se a resolução dessa complicação irá influenciar o curso ou a gravidade da doença.AbstractGingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood‐onset systemic lupus erythematosus (C‐SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C‐SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B‐cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush‐loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

A retrospective multicenter cohort study including 852 cSLE patients was performed in ten pediatric rheumatology centers (Brazilian cSLE group). An investigator meeting was held and all participants received database training. Uveitis was diagnosed through clinical assessment by the uveitis expert ophthalmologist of each center. Patients with and without uveitis were assessed for lupus clinical/laboratory features and treatments. Uveitis was observed in 7/852 cSLE patients (0.8%). Two of them had ocular complications: cataract and irreversible blindness in one patient and retinal ischemia with subsequent neovascularization and unilateral blindness in another. Uveitis was identified within the first 6 months of cSLE diagnosis in 6/7 patients (86%). Comparison of a subgroup of cSLE patients with (n = 7) and without uveitis (n = 73) and similar length of disease duration showed that patients with uveitis had increased SLEDAI-2K score (19 vs. 6; p

Orientador: Simone Appenzeller Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: O lúpus eritematoso sistêmico (LES) é uma doença autoimune de amplo espectro de sinais e sintomas. O cérebro dos pacientes com LES tem alterações estruturais e funcionais independente da ocorrência de manifestações neuropsiquiátricas (NP). Nosso principal objetivo foi analisar as alterações estruturais no LES juvenil (LESj) em um período de aproximadamente 23 meses e determinar se os níveis séricos do S100? e NF-H estariam associados com as alterações estruturais. Foram incluídos 86 pacientes com LESj [77 (89,5%) mulheres; com média de idade de 15,6±4,1 anos]. O grupo controle foi constituido por 95 voluntários saudáveis [75 (78,9%) mulheres; com média de idade de 16,4±3,4 anos]. Os pacientes foram avaliados quanto à presença de atividade da doença (SLEDAI) e dano cumulativo (SLICC). Todos os pacientes realizaram dois exames de ressonância magnética (RM) durante o período de 22,5±17,2 meses. Os volumes cerebrais, corpo caloso e de ventrículo foram determinados pelo programa semiautomático Neuroline®. A espessura cortical foi determinada pelo programa automático FreeSurfer®. Todos os pacientes completaram a avaliação cognitiva Montreal (MoCA), o Inventário de Depressão Beck (BDI) e o Inventário de Ansiedade Beck (BAI). Foram utilizados kits comercialmente para a análise dos níveis séricos de S100? e neurofilamento H (NF-H). A análise estatística foi realizada através de testes não-paramétricos. A média de progressão de perda de volume cerebral nos pacientes com LESj foi de 1,67±2,71% e observada em 44 (51,16%) pacientes. Vinte e três (26,7%) pacientes com LESj apresentaram redução de 2,31±5,48% do volume do corpo caloso. A média de progressão de aumento de ventrículo foi 5,03±9,81% e observada em 33 (38,37%) pacientes com LESj. Observamos 24 (25,35%; p

Childhood-onset systemic lupus erythematosus (cSLE) exhibits an aggressive clinical phenotype and severe complications. This could be due to a pro-inflammatory cytokine milieu. Therefore, we determined plasma levels of Th1 (IL-2, IFN-γ, TNF), Th2 (IL-4), Th17 (IL-17A, IL-6), and Treg (IL-10) cytokines in a cohort of cSLE patients and healthy controls, and we evaluated the association between these cytokines and disease activity. We conducted a cross-sectional study with 51 cSLE patients from two pediatric rheumatology services. Ten cSLE patients participated in a longitudinal follow-up study. Blood samples were collected from the same patient during active and inactive disease. Disease activity was evaluated according to SLE Disease Activity Index 2000 (SLEDAI-2K). Cytokines levels were measured by cytometric bead array technique. cSLE patients had higher IL-6 (P

No. of bitstreams: 0 Previous issue date: 2016-11-01 Objective The objective of this study was to assess Modified Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and European Consensus Lupus Activity Measurement (ECLAM) disease activity correlation in addition to their respective correlation to Pediatric Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (Ped-SDI), in juvenile systemic lupus erythematosus (JSLE). Methods The activity indices were scored retrospectively and summarized by adjusted means during follow-up. The Ped-SDI was scored during the last visit for those with more than six months follow-up. Pearson correlation between the Modified SLEDAI-2K and ECLAM, as well as Spearman correlations between the Modified SLEDAI-2K, ECLAM, and Ped-SDI were calculated. The receiver operating characteristic (ROC) curve was calculated for both activity indices discriminating damage measured by Ped-SDI. Results Thirty-seven patients with mean age at diagnosis 11 ± 2.9 years and mean follow-up time 3.2 ± 2.4 years were studied. The Modified SLEDAI-2K and ECLAM adjusted means were highly correlated (r = 0.78, p < 0.001). Similarly, Spearman correlation between the activity indices was also high (rs > 0.7, p < 0.001), but Modified SLEDAI-2K and ECLAM correlation with Ped-SDI was only moderate. ROC analysis discriminant performance for both activity indices resulted in area under curve (AUC) of 0.74 and 0.73 for Modified SLEDAI-2K and ECLAM, respectively. Conclusion The high correlation found between the Modified SLEDAI-2K and ECLAM adjusted means indicated that both tools can be equally useful for longitudinal estimates of JSLE activity.

No. of bitstreams: 0 Previous issue date: 2016-12-01 Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Chronic arthritis (CA) is an unusual condition in childhood-onset systemic lupus erythematosus (cSLE) and data in children is very limited. The aim of the study is to assess CA in a large population of cSLE patients, in a multicenter cross-sectional study including 852 cSLE patients followed in ten Pediatric Rheumatology referral services in state of São Paulo, Brazil. CA was observed in 32/852 (3.7 %) cSLE patients mostly in hands and ankles. Chronic monoarthritis was diagnosed in four cSLE patients, oligoarthritis in nine and polyarthritis in 19. In the latter group, six had rhupus syndrome. Two oligoarticular patients had Jaccoud’s arthropathy. CA was an isolated manifestation observed at disease onset in 13/32 (41 %) cSLE patients, and juvenile idiopathic arthritis (JIA) was the first diagnosis in 18/32 (56 %). The comparison of last visit of patients with CA and without this manifestation revealed higher frequency of splenomegaly (28 vs. 11 %, p = 0.002). The median of SLICC/ACR-DI score [1(0–9) vs. 0(0–7), p = 0.003] was significantly higher in CA patients compared to patients without this manifestation, likewise the frequency of musculoskeletal damage (31 vs. 9 % p = 0.001).

No. of bitstreams: 0 Previous issue date: 2015-01-01 Background: Data regarding the prevalence of chronic spontaneous urticaria (CSU) in childhood-onset systemic lupus erythematosus (cSLE) patients and possible associated factors are limited to a few case reports. The objectives of this study were to assess CSU in a large cSLE population, in order to evaluate the demographic data, clinical manifestations, disease activity/damage, laboratory abnormalities and treatment. Methods: A retrospective multicenter cohort study (Brazilian cSLE group) was performed in 10 Pediatric Rheumatology services and included 852 cSLE patients. CSU was diagnosed according to the guidelines of the European Academy of Allergy and Clinical Immunology, the Global Allergy and Asthma European Network, the European Dermatology Forum and the World Allergy Organization. Patients with CSU (evaluated at urticaria diagnosis) and patients without CSU (evaluated at the last visit) were assessed for lupus clinical/laboratory features and treatment. Results: CSU was observed in 10/852 cSLE patients (1.17%). The median of cSLE duration at urticaria diagnosis was 0 (-3 to 5) years. Comparison of cSLE patients with and without CSU revealed a greater frequency of constitutional symptoms (40 vs. 8%, p = 0.006), reticuloendothelial system involvement (30 vs. 3%, p = 0.003), mucocutaneous (90 vs. 28%, p < 0.0001) and musculoskeletal manifestations (50 vs. 6%, p < 0.0001) and methylprednisolone pulse therapy use (60 vs. 9%, p < 0.0001) in the former group. The frequency of immunosuppressive treatment was lower in patients with CSU (p = 0.018). The median SLE Disease Activity Index 2000 (12 vs. 2, p < 0.0001) and erythrocyte sedimentation rate (40 vs. 19 mm/1st hour, p = 0.024), was higher in patients with CSU. Conclusions: To our knowledge, this is the first study with evidence that CSU may be linked to cSLE. We also demonstrated that this particular skin manifestation occurs predominantly at disease onset and is associated with lupus moderate/high disease activity without major organ involvement.

Objective To determine the serum levels of Th1 (IL-12, IFN-γ,TNF-α) and Th2 (IL-5, IL-6 and IL-10) cytokines in childhood-onset SLE, first-degree relatives and healthy controls. To elucidate their association with disease activity, laboratory and treatment features. Methods We included 60 consecutive childhood-onset SLE patients [median age 18 years (range 10–37)], 64 first-degree relatives [median 40 (range 28–52)] and 57 healthy [median age 19 years (range 6–30 years)] controls. Controls were age and sex-matched to SLE patients. SLE patients were assessed for clinical and laboratory SLE manifestations, disease activity (SLEDAI), damage (SDI) and current drug exposures. Mood and anxiety disorders were determined through Becks Depression (BDI) and Anxiety Inventory (BAI). Th1 (IL-12, IFN-γ,TNF-α) and Th2 (IL-5, IL-6 and IL-10) cytokines levels were measured by ELISA and compared by non-parametric tests. Results Serum TNF-α ( p = 0.004), IL-6 ( p = 0.007) and IL-10 ( p = 0.03) levels were increased in childhood-onset SLE patients when compared to first-degree relatives and healthy controls. TNF-α levels were significantly increased in patients with active disease ( p = 0.014) and correlated directly with SLEDAI scores ( r = 0.39; p = 0.002). IL-12 ( p = 0.042) and TNF-α ( p = 0.009) levels were significantly increased in patients with nephritis and TNF-α in patients with depression ( p = 0.001). No association between cytokine levels and SDI scores or medication was observed. Conclusion Th1 cytokines may play a role in the pathogenesis of neuropsychiatric and renal manifestations in childhood-onset SLE. The correlation with SLEDAI suggests that TNF-α may be a useful biomarker for disease activity in childhood-onset SLE, however longitudinal studies are necessary to determine if increase of this cytokine may predict flares in childhood-onset SLE.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease and occurs worldwide in both children and adults. The estimated annual incidence among children is 2.22/100,000 and among adults is 23.2/100,000 in the United States. There is increasing understanding about differences in disease manifestations, medication use, and disease severity between those with childhood-onset SLE as compared with adult-onset SLE. Children have a more fulminant disease onset and course than adults with SLE, resulting in two to three times higher mortality. In future years, we anticipate more insight into the genetics between childhood-onset SLE and adult-onset SLE to help delineate the best therapies for both subsets of patients.
