    Objectives: We describe a case of systemic sclerosis (SS) with acro-osteolysis associated with cutaneous mucinosis, usually characterized by mucin deposition in the skin. The main differential diagnosis was multicentric reticulohistiocytosis due to the presentation of papulonodular skin lesions. Materials and methods: A physical examination, imaging studies and laboratory tests were performed.Results: Distal bone resorption was evident on plain radiographs, and skin biopsy confirmed mucinosis. The SS diagnosis was based on the clinical features, high levels of antinucleolar antibodies and typical nailfold capillaroscopy findings.Conclusion: To the best of our knowledge, this is the first description of cutaneous mucinosis accompanying SS with acro-osteolysi

    We investigated in Brazilian women with SLE the prevalence and levels of high avidity (HA) dsDNA antibodies and tested their correlation with lupus activity and biomarkers of renal disease. We also compared these correlations to those observed with total dsDNA antibodies and antibodies against nucleosome (ANuA). Autoantibodies were detected by ELISA, while C3 and C4 levels were determined by nephelometry. Urine protein/creatinine ratio was determined, and lupus activity was measured by SLEDAI-2K. The prevalence of total and HA dsDNA antibodies was similar to but lower than that verified for ANuA. The levels of the three types of antibodies were correlated, but the correlation was more significant between HA dsDNA antibodies and ANuA. High avidity dsDNA antibodies correlated positively with ESR and SLEDAI and inversely with C3 and C4. Similar correlations were observed for ANuA levels, whereas total dsDNA antibodies only correlated with SLEDAI and C3. The levels of HA dsDNA antibodies were higher in patients with proteinuria, but their levels of total dsDNA antibodies and ANuA were unaltered. High avidity dsDNA antibodies can be found in high prevalence in Brazilian women with SLE and are important biomarkers of active disease and kidney dysfunction

    OBJECTIVE: To describe the extra-articular manifestations (cardiac, renal, pulmonary, and neurological), usually not related to spondyloarthritis (SpA), in a large cohort of Brazilian patients. MATERIALS AND METHODS: This retrospective study analyzed 1,472 patients diagnosed with SpA and cared for at 29 health care centers distributed in the five major geographic regions in the country, participating in the Brazilian Registry of Spondyloarthritis (BRS). All patients were assessed for the prevalence of major extra-articular manifestations (cardiac, renal, pulmonary, and neurological), classified according to the diagnosis [ankylosing spondylitis (AS), psoriatic arthritis (PsA), reactive arthritis (ReA), arthritis associated with inflammatory bowel disease (IBD), undifferentiated spondyloarthritis (uSpA), and juvenile SpA], and according to the clinical presentation (axial, peripheral, mixed, and enthesitis). RESULTS: Of the patients with SpA assessed, 963 had AS, 271 PsA, 49 ReA, 48 arthritis associated with IBD, 98 uSpA, and 43 juvenile SpA. Cardiac involvement was reported in 44 patients (3.0%), pulmonary involvement in 19 (1.3%), renal involvement in 17 (1.2%), and neurological involvement in 13 patients (0.9%). Most patients with visceral involvement had AS or PsA, and the mixed (axial + peripheral) and/or predominantly axial clinical form. CONCLUSION: Cardiac, renal, pulmonary, and neurological extra-articular manifestations are quite infrequent in SpA, ranging from 0.9% to 3% in this large Brazilian cohort, and affected predominantly patients with AS and PsA.OBJETIVO: Descrever as manifestações extra-articulares (cardíacas, renais, pulmonares e neurológicas) geralmente não relacionadas às espondiloartrites (EpA) em uma grande coorte de pacientes brasileiros. MÉTODOS: Este estudo retrospectivo analisou 1.472 pacientes com o diagnóstico de EpA atendidos em 29 centros distribuídos pelas cinco principais regiões geográficas do Brasil, integrantes do Registro Brasileiro de Espondiloartrites. Todos os pacientes foram avaliados para a prevalência das principais manifestações extra-articulares (cardíacas, renais, pulmonares e neurológicas), divididas por diagnóstico [espondilite anquilosante (EA), artrite psoriásica (AP), artrite reativa (ARe), artrite associada a doença inflamatória intestinal (DII), EpA indiferenciada (EI) e EpA juvenil] e por forma clínica (axial, periférica, mista e entesítica). RESULTADOS: Dentre os pacientes avaliados com EpA, 963 apresentavam EA, 271 AP, 49 ARe, 48 artrite associada a DII, 98 EI e 43 EpA juvenil. Acometimento cardíaco foi observado em 44 pacientes (3,0%), seguido por acometimento pulmonar em 19 (1,3%), renal em 17 (1,2%) e neurológico em 13 pacientes (0,9%). A maioria dos casos de acometimento visceral ocorreu nos pacientes com EA ou AP e naqueles com forma clínica mista (axial e periférica) e/ou predominantemente axial. CONCLUSÃO: As manifestações extra-articulares cardíacas, renais, pulmonares e neurológicas são muito pouco frequentes nas EpA, variando de 0,9%-3% nesta grande coorte brasileira, estando mais associadas a EA e AP.37938

    Objetivo: analisar as variáveis demográficas e clínicas associadas à diminuição da qualidade de vida em uma grande coorte brasileira de pacientes com espondiloartrite (EpA). Métodos: Foi aplicado um protocolo de pesquisa único a 1.465 pacientes brasileiros classificados como tendo EpA de acordo com os critérios do European Spondyloarthropaties Study Group (ESSG), atendidos em 29 centros de referência em reumatologia do Brasil. Foram registradas as variáveis clínicas e demográficas. A qualidade de vida foi analisada por meio do questionário Ankylosing Spondylitis Quality of Life (ASQoL). Resultados: A pontuação média do ASQoL foi de 7,74 (+ 5,39). Ao analisar doenças específicas no grupo de EpA, as pontuações do ASQoL não apresentaram diferença estatisticamente significativa. Os dados demográficos mostraram piores escores de ASQoL associados ao gênero feminino (p = 0,014) e etnia negra (p < 0,001). Quanto aos sintomas clínicos, a dor na região glútea (p = 0,032), a dor cervical (p < 0,001) e a dor no quadril (p = 0,001), estiveram estatisticamente associadas a piores escores no ASQoL. O uso contínuo de fármacos anti-inflamatórios não esteroides (p < 0,001) e agentes biológicos (p = 0,044) esteve associado a escores mais elevados de ASQoL, enquanto outros medicamentos não interferiram nos escores do ASQoL. Conclusão: Nesta grande série de pacientes com EpA, o sexo feminino e a etnia negra, bem como sintomas predominantemente axiais, estiveram associados a uma qualidade de vida reduzida.Objective: to analyze quality of life and demographic and clinical variables associated to its impairment in a large Brazilian cohort of patients with spondyloarthritis (SpA). Methods: A common protocol of investigation was applied to 1465 Brazilian patients classified as SpA according to the European Spondyloarthropaties Study Group (ESSG) criteria, attended at 29 reference centers for Rheumatology in Brazil. Clinical and demographic variables were recorded. Quality of life was analyzed through the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results: The mean ASQoL score was 7.74 (± 5.39). When analyzing the specific diseases in the SpA group, the ASQoL scores did not present statistical significance. Demographic data showed worse scores of ASQoL associated with female gender (p = 0.014) and African-Brazilian ethnicity (p < 0.001). Regarding clinical symptoms, buttock pain (p = 0.032), cervical pain (p < 0.001) and hip pain (p = 0.001), were statistically associated with worse scores of ASQoL. Continuous use of nonsteroidal anti-inflammatory drugs (p < 0.001) and biologic agents (p = 0.044) were associated with higher scores of ASQoL, while the other medications did not interfere with the ASQoL scores. Conclusion: In this large series of patients with SpA, female gender and African-Brazilian ethnicity, as well as predominant axial symptoms, were associated with impaired quality of life

    Uso do rituximabe para o tratamento da plaquetopenia do lúpus eritematoso sistêmico: eficácia clínica e efeito nas moléculas de co-estimulação

    No full text
    Plaquetopenia é uma complicação não raramente vista no contexto do lúpus eritematoso sistêmico (LES). O seu tratamento inclui o uso de corticosteróide, imunossupressores, imunoglobulina humana e, eventualmente, esplenectomia. Descreve-se um caso de LES com plaquetopenia persistente a despeito do uso de prednisona e azatioprina, que respondeu satisfatoriamente ao uso de rituximabe (RTX). O estudo de citometria de fluxo mostrou depleção dos linfócitos B do sangue periférico, assim como uma queda das moléculas de co-estimulação após o uso da medicação. Não foi observado efeito colateral relacionado à infusão da substância. Dessa forma, o RTX parece estar indicado para casos selecionados de LES com plaquetopenia de difícil controle
