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.

Determine disease activity in a low income juvenile idiopathic arthritis (JIA) cohort. 164 JIA patients from families with less than US$ 4500.00/capita mean annual income followed in Fortaleza-CE, Brazil, were cross-sectionally evaluated between May 2015-April 2016. Mean age was 14 ± 5.1 years (95 female) with 10.31 ± 3.7 years disease duration. Polyarticular category predominated, with 63 (38.4%) patients, followed by 40 (24%) enthesitis-related (ERA), and 36 (22%) oligoarticular. All but 1 out of 84 parents declared less than US$ 10,000.00 annual family income. Eighty-eight (60.7%) were receiving methotrexate and 19 (13%) leflunomide including 12 (63%) using both; 46 (28%) were on biologic DMARD including 20 (43.5%) adalimumab, 17 (41.5) etanercept, 5 (10.8%) tocilizumab, 2 (4.2%) abatacept, and 1 (2.1%) each on infliximab and canakinumab. Mean CHAQ and JADAS27 were 0.36 ± 0.55 and 5.31 ± 8.5, respectively. Thirty-two (20%) out of 159 patients had deformities. A bivariate analysis revealed that polyarticular had more deformities than oligoarticular patients (p = 0.002; OR = 2.389; 95% CI 1.37-4.14). Logistic regression showed no association between high JADAS and family income (p = 0.339; OR = 1.45; 95% CI 0.67-3.31). A general linear model showed significantly lower CHAQ score in patients from families earning more as compared to those earning less than 300.00 US$ monthly (p = 0.002). This study reports JIA disease activity in a low income population. Low income apparently did not influence prognosis given the low mean JADAS27 and CHAQ scores vis-à-vis data from other cohorts.

We aimed to describe the serum levels of 25-hydroxyvitamin D (25OHD) in juvenile idiopathic arthritis (JIA) patients living in a low-latitude (3°43′S) region. Fifty JIA patients, 31 (62 %) female, seen between May 2012 and April 2013 in the northeast of Brazil had clinical data and serum collected for determination of 25OHD and parathyroid hormone (PTH) using a chemiluminescent ELISA; 20 age- and sex-matched controls were used for comparison. Mean age was 13.4 ± 4 years. Twenty-five (50 %), 15 (30 %), 4 (8 %), 4 (8 %), and 2 (4 %) patients were of the polyarticular, oligoarticular, systemic, enthesitis-related, and undifferentiated categories, respectively. Mean 25OHD was 31.6 ± 10 and 30.4 ± 5.7 ng/mL in patients and controls (P > 0.05), respectively; PTH was normal in JIA and controls; 25OHD was similar regardless of JIA category, disease activity, or severity measured by JADAS-27, CHAQ, or presence of joint deformities. Twenty-six (52 %), 20 (40 %), and 4 (8 %) patients were considered to have optimal, sufficient, and deficient 25OHD levels, respectively, whereas 11 (52 %) and 10 (48 %) controls had optimal and sufficient 25OHD. Ethnicity, body mass index, seasonal variation, and use of steroids did not influence 25OHD levels. This is the first study on 25OHD levels in JIA patients living in a low-latitude region, showing the lowest prevalence of vitamin D deficiency ever reported. Serum 25OHD was similar in JIA and controls and did not vary regardless of JIA category or severity.

Juvenile dermatomyositis (JDM) is a rare idiopathic chronic inflammatory disease that affects mainly muscle and skin. Cutaneous lesions may persist despite successful treatment of myositis. Of note, topical tacrolimus is a new immunosuppressive agent that has been used to treat atopic dermatitis with few reports in pediatric inflammatory myopathies. Three JDM patients (two males) were described, current age from 5.7 to 10.6 years. The initial therapy administered for these patients were: corticosteroid (oral in three and topical in one), antimalarial in three and methotrexate in two. All of them had refractory skin lesions (malar rash, extensive rash and/or cutaneous vasculitis) after significant improvement of muscle weakness. Topical tacrolimus 0.03% was used twice daily after failure of previous treatment. The features of lesions were evaluated according to extension and severity at start of drug and after 8 and 16 weeks. At the second evaluation (8 weeks), remarkably one patient had complete improvement of malar rash and extensive rash in limbs and trunk, and two had partial improvement of malar rash and cutaneous vasculitis. At the third evaluation (16 weeks), two patients had complete resolution of lesions and one had persistent malar rash and moderate lumbar and gluteus rash. In the last patient, the improvement of skin lesions was reached only after 16 weeks of cyclosporine use. None of them had adverse effects. Topical tacrolimus could be considered in JDM patients with refractory cutaneous manifestations. Further randomized controlled trials with this agent should be performed in this inflammatory disease.

Introdução: As infecções são importantes causas de morbidade e mortalidade em pacientes com lúpus eritematoso sistêmico juvenil (LESJ). No entanto, estudos avaliando somente infecções fúngicas invasivas (IFI) em pacientes com LESJ são restritos a relatos de casos ou série de casos, sem qualquer avaliação sistemática dos possíveis fatores de risco ou desfechos associados. A escassez de dados referentes às IFI em pacientes com LESJ e seu impacto sobre as características da doença em uma grande população levou ao desenvolvimento deste estudo multicêntrico. Objetivos: Estudar a prevalência, fatores de risco e mortalidade de IFI em pacientes com LESJ. Método: Um estudo de coorte multicêntrico retrospectivo foi realizado com 852 pacientes com LESJ de 10 Serviços de Reumatologia Pediátrica do Estado de São Paulo. Uma reunião foi realizada e todos os pesquisadores foram treinados para o preenchimento do banco de dados. As IFI foram diagnosticadas de acordo com as definições revisadas pelo grupo de consenso EORTC/MSG (comprovadas, prováveis ou possíveis). Foram coletados dados acerca de dados demográficos, características clínico-laboratoriais, atividade da doença (SLEDAI-2K), dano cumulativo (SLICC/ACR-DI) e tratamento, além de características e complicações das IFI. Resultados: IFI foram diagnosticadas em 33/852 (3,9%) pacientes com LESJ. IFI comprovadas foram diagnosticadas em 22 pacientes, IFI prováveis em 5 e IFI possíveis em 6. Os tipos de IFI encontradas foram: candidíase em 20 pacientes, aspergilose em 9, criptococose em 2, histoplasmose disseminada em um e paracoccidioidomicose em um. A mediana de duração da doença foi menor (1,0 vs. 4,7 anos, p < 0,0001), com maiores escores de SLEDAI-2K atual [19,5 (0-44) vs. 2 (0-45), p < 0,0001] e dose atual de prednisona [50 (10-60) vs. 10 (2-90) mg/dia, p < 0,0001] em pacientes com IFI em comparação com os pacientes sem IFI. A frequência de óbito foi maior no grupo com IFI (51% vs. 6%, p < 0,0001). A análise de regressão logística revelou que SLEDAI-2K atual (OR=1,108, IC 95%=1,057- 1,163, p < 0,0001), dose atual de prednisona (OR=1,046, IC 95%=1,021-1,071; p < 0,0001) e duração da doença (OR=0,984, IC 95%=0,969-0,998, p=0,030) foram fatores de risco independentes para IFI (R2 Nagelkerke 0,425). Conclusão: Este foi o primeiro estudo que caracterizou IFI em pacientes com LESJ. Identificou-se que a atividade da doença e uso de glicocorticoides foram os principais fatores de risco para estas infecções potencialmente graves, principalmente nos primeiros anos de curso da doença e com uma elevada taxa mortalidade Introduction: Infections are an important cause of morbidity and mortality in childhoodonset systemic lupus erythematosus (cSLE) patients. However, studies evaluating solely invasive fungal infections (IFI) in cSLE patients are restricted to case reports or case series without any systematic evaluation of the possible associated risk factors and outcome in pediatric lupus population. The scarcity of data regarding IFI in cSLE patients and its impact on disease characteristics in a large population led to the development of this multicenter study. Objective: To study the prevalence, risk factors and mortality of IFI in cSLE patients. Methods: A retrospective multicenter cohort study was performed in 852 cSLE patients from 10 Pediatric Rheumatology services. An investigator meeting was held and all participants received database training. IFI were diagnosed according to EORTC/MSG Consensus Group criteria (proven, probable and possible). Demographic data, clinical, laboratorial, disease activity (SLEDAI-2K), cumulative damage (SLICC/ACR-DI) and treatment were collected. IFI were characterized and its outcome were also evaluated. Results: IFI were observed in 33/852 (3.9%) cSLE patients. Proven IFI was diagnosed in 22 cSLE patients, probable IFI in 5 and possible IFI in 6. Types of IFI were: 20 candidiasis, 9 aspergillosis, 2 cryptococcosis, one disseminated histoplasmosis and one paracoccidioidomycosis. The median of disease duration was lower (1.0 vs. 4.7 years, p < 0.0001), with a higher current SLEDAI-2K [19.5 (0-44) vs. 2 (0-45), p < 0.0001] and current prednisone dose [50 (10-60) vs. 10 (2-90) mg/day, p < 0.0001] in patients with IFI compared to those without IFI. The frequency of death was higher in the former group (51% vs. 6%, p < 0.0001). Logistic regression analysis revealed that current SLEDAI-2K (OR=1.108; 95%CI=1.057-1.163; p < 0.0001), prednisone current dose (OR=1.046; 95%CI=1.021-1.071; p < 0.0001) and disease duration (OR=0.984; 95%CI=0.969-0.998; p=0.03) were independent risk factors for IFI (R2 Nagelkerke 0.425). Conclusion: This was the first study that characterized IFI in cSLE patients. We identified that disease activity and glucocorticoid use were the main risk factors for these life-threatening infections, mainly in the first years of disease course and with a high rate of fatal outcome
