Abstract in Portuguese
Introdução: Estudos avaliando a prevalência de urticária crônica espontânea (UCE) no lúpus eritematoso sistêmico juvenil (LESJ), assim como possíveis fatores associados são restritos a poucos relatos de caso. Objetivos: Avaliar a prevalência de UCE em uma população expressiva de LESJ, assim como sua possível associação com dados demográficos, manifestações clínicas, alterações laboratoriais, atividade/dano cumulativo da doença e tratamento. Métodos: Um estudo de coorte multicêntrico retrospectivo foi realizado em 10 serviços de Reumatologia Pediátrica provenientes do Grupo Brasileiro de Lúpus e incluiu 852 pacientes com LESJ. UCE foi diagnosticada de acordo com o guideline do EAACI/GA2LEN/EDF/WAO. Os pacientes foram divididos em dois grupos para a avaliação das manifestações clínicas atuais, assim como parâmetros laboratoriais e tratamento: pacientes que tiveram UCE (avaliados durante o diagnóstico da urticária) e pacientes sem UCE (avaliados na última consulta). Resultados: A presença de urticária foi observada em 10/852 (1,17%) pacientes com LESJ. A comparação entre os pacientes com LESJ com e sem UCE revelou uma maior frequência de sintomas constitucionais (40% vs. 8%, p=0,005), envolvimento do sistema reticuloendotelial (30% vs. 3%, p=0,003), sintomas mucocutâneos (90% vs. 28%, p < 0,0001), manifestações musculoesqueléticas (50% vs. 6%, p < 0,0001) e necessidade de pulso de metilprednisolona (60% vs. 8%, p < 0,0001) no grupo com UCE. A frequência do uso de imunossupressor foi menor nos pacientes com UCE (20% vs. 61%, p=0,017). As medianas do SLEDAI-2K (12 vs. 2, p < 0,0001) e do VHS (40 vs. 19 mm/1a hora, p=0,024), foram maiores nos pacientes com UCE. Conclusões: Este foi o primeiro estudo que evidenciou a possível relação da UCE com LESJ. A UCE aconteceu predominantemente no início do curso do LESJ e esteve associada com uma atividade de doença moderada/alta e sem envolvimento de órgãos nobres

Abstract in English
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 few case reports. The objectives of the present study were to assess CSU in a large cSLE population evaluating 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 including 852 cSLE patients. CSU was diagnosed according to EAACI/GA2LEN/EDF/WAO Guidelines. Patients with CSU (evaluated at urticaria diagnosis) and patients without CSU (evaluated at last visit) were assessed for lupus clinical/laboratory features and treatment. Results: CSU was observed in 10/852 (1.17%) cSLE patients. Comparison of cSLE patients with and without CSU revealed a higher frequency of constitutional (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. 8%, p < 0.0001) in the former group. The frequency of immunosuppressive treatment was lower in patients with CSU(p=0.017). The median SLEDAI-2K (12 vs. 2, p < 0.0001) and ESR (40 vs. 19 mm/1sthour, p=0.024), was higher in patients with CSU. Conclusions: To our knowledge this was the first study that evidenced that CSU may be linked to cSLE. We also demonstrated that this particular skin manifestation occurs predominantly at disease onset and it was associated with lupus moderate/high disease activity without major organ involvement
