Abstract Background: Human herpesviruses (HHVs) are responsible for a significant number of clinical manifestations in systemic lupus erythematous (SLE) patients. The aim of this study was to determine the frequency of active HHV infections in SLE patients and correlating them with disease activity. Methods: Serum samples were collected from 71 SLE patients and their DNAs were extracted and analyzed to detect HHV-DNA viruses using the nucleic acid amplification technique. Results: Fifteen out of the 71 (21.1%) patients tested positive for the HHV-DNA virus. Of them, 11/15 HHV-DNA-positive patients (73.3%) had SLE activity index (SLEDAI - Systemic Lupus Erythematosus Disease Activity Index) ≥8 (p = 0.0001). Active HCMV infection was the mostly frequently observed infection, occurring in 6/15 patients (40%). The frequencies of other active viral infections were 22% for HSV-1, 16.7% for HHV-7, and 5.5% for HSV-2. Viral coinfection (two or more viruses detected in the same sample) occurred in three patients (16.7%). Active HHV infections in SLE patients are more frequent in those with active SLE (≥8), who is at high risk of HHV reactivation and HCMV disease. Conclusion: Viral surveillance is important to identify active HHV infections that can cause clinical symptoms and other complication in SLE patients.

Resumo Objetivo Avaliar os efeitos da gravidez em pacientes com lúpus eritematoso sistêmico (LES). Métodos Estudo de coorte retrospectivo. Os dados foram coletados de prontuários de mulheres com LES que engravidaram de janeiro de 2002 a dezembro de 2012 na Universidade Estadual de Campinas, São Paulo, Brasil. Lúpus eritematoso sistêmico e atividade da doença foram definidos segundo o American College of Rheumatology e os critérios doÍndice deAtividadedaDoença de Lúpus Eritematoso (SLEDAI, nasigla eminglês), respectivamente. As médias, os desvios-padrão (DP), as porcentagens e as correlações foram realizados utilizando o software SAS, versão 9.4 (SAS Institute Inc., Cary, NC, US). Resultados Obtivemos dados de 69 gestações em58mulheres. Durante a gravidez, a reatividade da doença foi observada em 39.2% (n = 27). As manifestações mais comuns foram em pacientes com doença renal prévia, e ocorreram principalmente no terceiro trimestre e no puerpério. Atividade renal ocorreu em 24,6% (n = 17), e atividade grave, em 16% (n = 11). De todos os partos, 75% (n = 48) foram por cesariana. Dois óbitos maternos ocorreram (3%). A prematuridade foi a principal complicação nos recém-nascidos. A taxa de aborto foi de 8,7%. O índice SLEDAI grave durante a gestação foi associado à prematuridade (100%) e à morte perinatal (54%). Conclusão O resultado materno-fetal é pior no LES quando as mulheres sofrem crise de reativação durante a gravidez. Os melhores desfechos materno-fetais ocorrem quando a doença está em remissão por pelo menos 6 meses anteriores à gestação.

Abstract Objective To evaluate the effects of pregnancy in systemic lupus erythematosus (SLE) patients. Methods The present article is a retrospective cohort study. Datawere collected from medical records of pregnant women with SLE from January 2002 to December 2012 at Universidade Estadual de Campinas, in the city of Campinas, state of São Paulo, Brazil. Systemic lupus erythematosus and disease activity were defined according to the American College of Rheumatology and the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) criteria respectively. The means, standard deviations (SDs), percentages and correlations were performed using the SAS software, version 9.4 (SAS Institute Inc., Cary, NC, US). Results We obtained data from 69 pregnancies in 58 women. During pregnancy, a new flare was observed in 39.2% (n = 27). The manifestations were most common in patients with prior kidney disease, and mainly occurred during the third quarter and the puerperium. Renal activity occurred in 24.6% (n = 17), and serious activity, in 16% (n = 11). Of all deliveries, 75% (n = 48) were by cesarean section. Twomaternal deaths occurred (3%). Preterm birth was themain complication in the newborns. The abortion rate was 8.7%. Severe SLEDAI during pregnancy was associated with prematurity (100%) and perinatal death (54%). Conclusion Thematernal-fetal outcome is worse in SLE when thewomen experience a flare during pregnancy. The best maternal-fetal outcomes occur when the disease is in remission for at least 6 months before the pregnancy.

Resumo Objetivo Descrever características clínicas, laboratoriais, radiológicas e evolutivas de mielopatia no lúpus eritematoso sistêmico (LES). Pacientes e métodos Foi feita análise retrospectiva de uma coorte de 1.193 pacientes com LES (critérios ACR) para identificar os pacientes com mielopatia (ACR neuropsiquiátrico). A atividade de doença foi analisada pelo Índice de Atividade do LES (Sledai) na data do evento e a capacidade funcional pela Escala Expandida do Estado de Incapacidade (EDSS) na última consulta. Resultados Foram identificados 14 (1,2%) pacientes com mielopatia. Todas eram mulheres com média de 30 anos (DP ± 11,5 anos). A mielopatia ocorreu no diagnóstico do LES em quatro (28%) e em nove (64%) havia outro tipo de manifestação neuropsiquiátrica associada. Recorrência do quadro neurológico foi observado em uma (7%) paciente. Atividade de doença foi observada em dois (14%) pacientes. O líquido cefalorraquidiano apresentava pleocitose em sete (53%) pacientes anticorpos antifosfolípides eram positivos em cinco (45%). A ressonância magnética (RM) demonstrou hipersinal em T2 com predomínio do comprometimento longitudinal em seis (86%) pacientes. A maioria foi tratada com corticosteroides e ciclofosfamida endovenosos. Nenhuma paciente teve completa recuperação e quatro (36%) tinham escores altos da EDSS. Óbito foi observado em três (21%) durante episódio de mielopatia, por septicemia durante ou após terapia imunossupressora. Conclusões A mielopatia ocorreu em 14 (1,2%) dos pacientes da nossa coorte e pode ser a primeira manifestação da doença e ocorrer independentemente de atividade sistêmica da doença. Embora rara, é de grande morbimortalidade, pode ser recorrente e a RM é fundamental para o diagnóstico.

Abstract Objective To describe clinical, laboratory, radiological and progression characteristics of myelopathy in systemic lupus erythematosus (SLE). Patients and methods A retrospective analysis was performed on a cohort of 1193 patients with SLE (ACR criteria) in order to identify patients with myelopathy (neuropsychiatric ACR). Disease activity was assessed by the SLE activity index (SLEDAI) on the date of the event and functional capacity was assessed by the Expanded Disability Status Scale (EDSS) at the last visit. Results We identified 14 (1.2%) patients with myelopathy. All were women with a mean age of 30 ± 11.5 years. Myelopathy occurred at the diagnosis of SLE in four (28%) patients; and nine (64%) patients had another type of neuropsychiatric manifestation associated. Neurological recurrence was observed in one (7%) patient. Disease activity was observed in 2 (14%) patients. Cerebrospinal fluid presented pleocytosis on 7 (53%) patients; antiphospholipid antibodies were positive in 5 (45%). Magnetic resonance imaging (MRI) showed T2 hyperintensity with a predominance of longitudinal involvement in 6 (86%) patients. Most were treated with intravenous corticosteroids and cyclophosphamide. No patient had full recovery and four (36%) had high EDSS scores. Three (21%) patients died from sepsis early in the course of their myelopathy, during or after immunosuppressive therapy. Conclusions Myelopathy occurred in 14 (1.2%) of the patients in our cohort and this may be the first manifestation of the disease occurring independently of systemic disease activity. Although rare, myelopathy shows great morbidity and mortality, can be recurrent and MRI is critical for diagnosis.

Resumo O lúpus eritematoso sistêmico é uma doença autoimune, que provoca diversas repercussões psicológicas que têm sido estudadas por meio de pesquisas qualitativas. Essas são consideradas relevantes, uma vez que reveladoras da amplitude vivenciada pelos pacientes. Face a essa relevância, este artigo buscou mapear a produção qualitativa na temática, oriunda de estudos de vivências de pacientes adultos de ambos os gêneros e que tivessem usado como instrumento a entrevista semiestruturada e/ou a observação de campo, além do critério de amostragem por saturação na definição do número de participantes de cada estudo. O levantamento foi feito nas bases de dados Pubmed, Lilacs, Psycinfo e Cochrane em busca de produções em língua inglesa e portuguesa publicadas entre janeiro de 2005 e junho de 2012. Os 19 artigos revisados que se ocuparam com pacientes em fase aguda da doença revelaram temas categorizados em oito tópicos que contemplaram o processo vivenciado nas diversas etapas, desde o desencadeamento da doença, passando pelo conhecimento do diagnóstico pela e compreensão das manifestações da doença, até o tratamento medicamentoso e os cuidados gerais, a evolução e o prognóstico. Apontam também a difícil compreensão pelos pacientes do que consiste a chamada fase de remissão, bem como nos revela que se trata de uma fase clínica pouco explorada pelos estudos psicológicos.

Abstract Systemic lupus erythematosus is an autoimmune disease that causes many psychological repercussions that have been studied through qualitative research. These are considered relevant, since they reveal the amplitude experienced by patients. Given this importance, this study aims to map the qualitative production in this theme, derived from studies of experiences of adult patients of both genders and that had used as a tool a semi-structured interview and/or field observations, and had made use of a sampling by a saturation criterion to determine the number of participants in each study. The survey was conducted in Pubmed, Lilacs, Psycinfo e Cochrane databases, searching productions in English and Portuguese idioms published between January 2005 and June 2012. The 19 revised papers that have dealt with patients in the acute phase of the disease showed themes that were categorized into eight topics that contemplated the experienced process at various stages, from the onset of the disease, extending through the knowledge of the diagnosis and the understanding of the manifestations of the disease, drug treatment and general care, evolution and prognosis. The collected papers also point to the difficulty of understanding, of the patients, on what consists the remission phase, revealing also that this is a clinical stage underexplored by psychological studies.

OBJECTIVES: To determine the serum interleukin-17 (IL-17) levels in childhood-onset systemic lupus erythematosus patients and to evaluate the association between IL-17 and clinical manifestations, disease activity, laboratory findings and treatment. METHODS: We included 67 consecutive childhood-onset systemic lupus erythematosus patients [61 women; median age 18 years (range 11-31)], 55 first-degree relatives [50 women; median age 40 years (range 29-52)] and 47 age- and sex-matched healthy controls [42 women; median age 19 years (range 6-30)]. The childhood-onset systemic lupus erythematosus patients were assessed for clinical and laboratory systemic lupus erythematosus manifestations, disease activity [Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)], cumulative damage [Systemic Lupus International Collaborating Clinics/American College of Rheumatology (ACR) Damage Index] and current drug use. Serum IL-17 levels were measured by an enzyme-linked immunosorbent assay using commercial kits. RESULTS: The median serum IL-17 level was 36.3 (range 17.36-105.92) pg/mL in childhood-onset systemic lupus erythematosus patients and 29.47 (15.16-62.17) pg/mL in healthy controls (p=0.009). We observed an association between serum IL-17 levels and active nephritis (p=0.01) and migraines (p=0.03). Serum IL-17 levels were not associated with disease activity (p=0.32), cumulative damage (p=0.34), or medication use (p=0.63). CONCLUSION: IL-17 is increased in childhood-onset systemic lupus erythematosus and may play a role in the pathogenesis of neuropsychiatric and renal manifestations. Longitudinal studies are necessary to determine the role of IL-17 in childhood-onset systemic lupus erythematosus.

Objetivo Elaborar recomendações para o diagnóstico, manejo e tratamento da nefrite lúpica no Brasil. Método Revisão extensa da literatura com seleção dos artigos com base na força de evidência científica e opinião dos membros da Comissão de Lúpus Eritematoso Sistêmico da Sociedade Brasileira de Reumatologia. Resultados e conclusões 1) A biópsia renal deve ser feita sempre que possível e houver indicação e quando não for possível, o tratamento deve ser orientado com base na inferência da clase histológica. 2) Devem ser implementados medidas e cuidados idealmente antes do início do tratamento, com ênfase na atenção ao risco de infecção. 3) Devem-se compartilhar riscos e benefícios do tratamento com pacientes e familiares. 4) O uso da hidroxicloroquina (preferencialmente) ou difosfato de cloroquina é recomendado para todos os pacientes (exceto contraindicação) durante as fases de indução e manutenção. 5) A avaliação da eficácia do tratamento deve ser feita com critérios objetivos de resposta (remissão completa/remissão parcial/refratariedade). 6) Os IECA e/ou BRA são recomendados como antiproteinúricos para todos os pacientes (exceto contraindicação). 7) A identificação de sinais clínicos e/ou laboratoriais sugestivos de GN laboratoriais sugestivos de glomerulonefrite proliferativa ou membranosa deve indicar início imediato de terapia específica incluindo corticosteroides e agente imunossupressor, mesmo que não seja possível comprovação histológica. 8) O tempo de uso dos imunossupressores deve ser no mínimo de 36 meses, mas eles podem ser mantidos por períodos mais longos. A sua suspensão só deve ser feita quando o paciente atingir e mantiver remissão completa sustentada. 9) Deve-se considerar nefrite lúpica refratária quando a remissão completa ou parcial não for alcançada após 12 meses de tratamento adequado, quando uma nova biópsia renal deve ser considerada para auxiliar na identificação da causa da refratariedade e decisão terapêutica.

Objective To develop recommendations for the diagnosis, management and treatment of lupus nephritis in Brazil. Method Extensive literature review with a selection of papers based on the strength of scientific evidence and opinion of the Commission on Systemic Lupus Erythematosus members, Brazilian Society of Rheumatology. Results and conclusions (1) Renal biopsy should be performed whenever possible and if this procedure is indicated; and, when the procedure is not possible, the treatment should be guided with the inference of histologic class. (2) Ideally, measures and precautions should be implemented before starting treatment, with emphasis on attention to the risk of infection. (3) Risks and benefits of treatment should be shared with the patient and his/her family. (4) The use of hydroxychloroquine (preferably) or chloroquine diphosphate is recommended for all patients (unless contraindicated) during induction and maintenance phases. (5) The evaluation of the effectiveness of treatment should be made with objective criteria of response (complete remission/partial remission/refractoriness). (6) Angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers are recommended as antiproteinuric agents for all patients (unless contraindicated). (7) The identification of clinical and/or laboratory signs suggestive of proliferative or membranous glomerulonephritis should indicate an immediate implementation of specific therapy, including corticosteroids and an immunosuppressive agent, even though histological confirmation is not possible. (8) Immunosuppressives must be used during at least 36 months, but these medications can be kept for longer periods. Its discontinuation should only be done when the patient could achieve and maintain a sustained and complete remission. (9) Lupus nephritis should be considered as refractory when a full or partial remission is not achieved after 12 months of an appropriate treatment, when a new renal biopsy should be considered to assist in identifying the cause of refractoriness and in the therapeutic decision.

Objetivo: Avaliar pacientes com LES estável, sem comprometimento respiratório evidente, por meio do TC6M. Casuística e métodos: Foram recrutados 45 pacientes com LES estável. Foi utilizado o protocolo ATS/ERS para TC6M, tendo sido escolhidos dois parâmetros com pontos de corte. Resultados: Quarenta e dois dos pacientes eram mulheres.A média de idade foi 39 ± 11,4 anos; a duração média da doença, 121 ± 93,1 meses; valor médio de MRC 2 ± 0; CVF média 85,9 ± 34,2%; VEF1 médio 67,5 ± 21,6%; PIM média 82 ± 58,4%; PEM média 78 ± 37,3%; frequência cardíaca média em repouso 75 ± 12,8 bpm; frequência respiratória média em repouso 19 ± 5,3 bpm; distância média no TC6M 478 ± 82 m; SpO2 média em repouso 98 ± 0,8%; queda média em SpO2 4 ± 6 pontos. Quando a população em estudo foi dividida de acordo com o valor de corte de 400 m de distância caminhada, a frequência cardíaca imediatamente antes do teste foi significativamente menor naqueles participantes que caminharam menos de 400 m (p = 0,0043), da mesma forma que o valor da escala de Borg (p = 0,0036). De acordo com a presença de saturação ≥ 4, a frequência cardíaca ao final do teste estava significativamente mais elevada naqueles participantes exibindo dessaturação (p = 0,0170); PEM (p = 0,0282) e TC6M (p = 0,0291) estavam significativamente menores e PIM revelou uma tendência para diminuir (p = 0,0504). CVF < limite inferior do normal foi achado significativamente associado com o grupo com dessaturação (p = 0,0274). Conclusão: Comparado com TC6M, a dessaturação foi o indicador mais apropriado para localizar os pacientes com os índices mais comprometidos nos testes de função respiratória.

Objective: Evaluate SLE stable patients, without overt respiratory compromise, by means of 6MWT. Casuistic and methods: Forty-five stable SLE patients were enrolled. The ATS/ERS protocol for 6MWT, was used and two parameters with cut-off points were chosen. Results: Forty-two patients were women. The mean age was 39 ± 11.4 years; mean duration of disease, 121 ± 93.1 months; mean value of MRC, 2 ± 0; mean FVC, 85.9 ± 34.2%; mean FEV1, 67.5 ± 21.6%; mean MIP, 82 ± 58.4%; mean MEP, 78 ± 37.3%; mean heart rate at rest, 75 ± 12.8 bpm; mean respiratory rate at rest, 19 ± 5.3 bpm; mean 6MWD, 478 ± 82 m; mean SpO2 at rest was 98 ± 0.8%; mean fall in SpO2, 4 ± 6 points. When the study population was divided according to the 400-m walk distance cut-off value, the heart rate immediately before the test was significant lower in those participants who walked less than 400 m (p = 0.0043), just like the value of Borg scale (p = 0.0036); according to the presence of saturation ≥ 4, heart rate at the end of the test was significantly higher in those participants who were showing desaturation (p = 0.0170); MEP (p = 0.0282) and 6MWD (p = 0.0291) were significantly lower, and MIP showed a tendency towards being smaller (p = 0.0504). FVC < normal inferior limit was significantly associated with the group with desaturation (p = 0.0274). Conclusion: Compared to 6MWD, desaturation was better suited to find the patients with the most compromised indexes in respiratory function tests.

OBJETIVO: Avaliar a frequência do HLA classes I e II e sua associação com a manifestação cutânea da vasculite reumatoide (VR) em pacientes brasileiros. PACIENTES E MÉTODOS: Durante um ano foram selecionados 130 pacientes com artrite reumatoide (AR), classificados de acordo com os critérios do American College of Rheumatology de 1987. Os pacientes foram submetidos a um questionário clínico e laboratorial para exclusão de outras causas de vasculopatia cutânea (neoplasia, infecções, uso de drogas ilícitas, diabetes mellitus e tabagismo). Setenta e três foram excluídos por apresentarem algum fator de risco para outras causas de vasculopatias. Cinquenta e sete foram incluídos no estudo sem fator de risco para outras causas de vasculopatia, dos quais 17 apresentavam VR de acordo com os critérios de 1984 de Scott e Bacon. Foram analisados dados demográficos, tempo de diagnóstico de AR, atividade da doença (DAS28) e presença de fator reumatoide e de anticorpos antipeptídeo citrulinado cíclico. Alelos HLA foram tipificados usando-se a reação em cadeia da polimerase-DNA amplificada por hibridização de baixa resolução com sequências específicas de sondas. RESULTADOS: A comparação entre os 40 pacientes sem VR e os 17 pacientes com VR demonstrou uma frequência aumentada do HLA-B*14 (Pc = 0,168) e do HLA-Cw*08 (Pc = 0,084) em pacientes com VR, e uma frequência aumentada do HLA-DRB5*01 (Pc = 0,048) em pacientes sem VR. CONCLUSÃO: O HLA-DRB5*01 pode conferir proteção contra essa manifestação extra-articular da AR.

OBJECTIVE: To evaluate the frequency of HLA classes I and II and their association with the cutaneous manifestation of rheumatoid vasculitis (RV) in Brazilian patients. PATIENTS AND METHODS: During one year we selected 130 patients with rheumatoid arthritis (RA) classified according to the American College of Rheumatology, 1987. All patients underwent a clinical and laboratory questionnaire to exclude other causes of cutaneous vasculopathy (neoplasia, infections, illicit drug use, diabetes mellitus, and tobaccoism). Seventy-three patients with any risk factor for other causes of vasculopathy were excluded. Fifty-seven without risk factors for other causes of vasculopathy were included in the study, 17 with RV according to Scott and Bacon's criteria, 1984. Demographic data, time of RA diagnosis, disease activity (DAS28), presence of rheumatoid factor, and anti-cyclic citrullinated peptide antibodies were analyzed. The HLA alleles were typed using the DNA-amplified polymerase chain reaction with low-resolution hybridization and sequence-specific primers. RESULTS: The comparison between the 40 patients without RV and the 17 patients with RV showed an increased frequency of HLA-B*14 (Pc = 0.168) and HLA-Cw*08 (Pc = 0.084) in patients with RV and an increased frequency of HLA-DRB5*01 (Pc = 0.048) in patients without RV. CONCLUSION: The HLA-DRB5*01 may confer protection against that extra-articular manifestation of RA.

OBJECTIVE: To determine the serum levels of interferon alpha in childhood-onset systemic lupus erythematosus patients, their first-degree relatives and healthy controls and to evaluate the associations between serum interferon alpha and disease activity, laboratory findings and treatment features. METHODS: We screened consecutive childhood-onset systemic lupus erythematosus patients in a longitudinal cohort at the pediatric rheumatology unit of the State University of Campinas between 2009 and 2010. All patients demonstrated disease onset before the age of 16. Disease status was assessed according to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). Interferon alpha levels were measured using an enzyme-linked immunoabsorbent assay. RESULTS: We included 57 childhood-onset systemic lupus erythematosus patients (mean age 17.33±4.50), 64 firstdegree relatives (mean age 39.95±5.66), and 57 healthy (mean age 19.30±4.97) controls. Serum interferon alpha levels were significantly increased in childhood-onset systemic lupus erythematosus patients compared to their firstdegree relatives and healthy controls. Interferon alpha levels were significantly increased in patients with positive dsDNA antibodies, patients with cutaneous vasculitis, patients with new malar rash and patients who were not receiving medication. Interferon alpha levels correlated with C3 levels and systemic lupus erythematosus Disease Activity Index scores. In addition, we observed an inverse correlation between patient age and interferon alpha levels. CONCLUSION: Interferon alpha may play a role in the pathogenesis of childhood-onset systemic lupus erythematosus, especially in cutaneous manifestations and dsDNA antibody formation. The observation that interferon alpha levels are increased in patients who are not taking medication should be investigated in longitudinal studies to determine whether elevated interferon alpha levels may predict systemic lupus erythematosus flares.

INTRODUCTION: Epstein-Barr virus exposure appears to be an environmental trigger for rheumatoid arthritis that interacts with other risk factors. Relationships among anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status have been observed in patients with rheumatoid arthritis from different populations. OBJECTIVE: To perform an association analysis of anti-Epstein-Barr nuclear antigen-1 antibodies, anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status in Brazilian patients with rheumatoid arthritis. METHODS: In a case-control study, 140 rheumatoid arthritis patients and 143 healthy volunteers who were matched for age, sex, and ethnicity were recruited. Anti-Epstein-Barr nuclear antigen-1 antibodies and anti-cyclic citrullinated peptide antibodies were examined using an enzyme-linked immunosorbent assay, and shared epitope alleles were identified by genotyping. Smoking information was collected from all subjects. A comparative analysis of anti-Epstein-Barr nuclear antigen-1 antibodies, anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status was performed in the patient group. Logistic regression analysis models were used to analyze the risk of rheumatoid arthritis. RESULTS: Anti-Epstein-Barr nuclear antigen-1 antibodies were not associated with anti-cyclic citrullinated peptide antibodies, shared epitope alleles, or smoking status. Anti-cyclic citrullinated peptide antibody positivity was significantly higher in smoking patients with shared epitope alleles (OR = 3.82). In a multivariate logistic regression analysis using stepwise selection, only anti-cyclic citrullinated peptide antibodies were found to be independently associated with rheumatoid arthritis (OR = 247.9). CONCLUSION: Anti-Epstein-Barr nuclear antigen-1 antibodies did not increase the risk of rheumatoid arthritis and were not associated with the rheumatoid arthritis risk factors studied. Smoking and shared epitope alleles were correlated with anti-cyclic citrullinated peptide-antibody-positive rheumatoid arthritis. Of the risk factors, only anticyclic citrullinated peptides antibodies were independently associated with rheumatoid arthritis susceptibility.

Em quadros de monoartrite crônica devem ser investigadas doenças inflamatórias como a artrite reumatoide (AR), doenças infecciosas como a tuberculose e outras doenças que causem espessamento sinovial e derrame articular como sinovite vilonodular pigmentada (SVNP), hemangioma sinovial, osteocondromatose sinovial e lipoma arborescente sinovial. Relatamos o caso de uma jovem paciente com quadro de monoartrite em ombro, cujo exame por imagem mostrou sinovite e cujo exame histopatológico obtido através de artroscopia com biópsia revelou tratar-se de SVNP. RELATO DO CASO: J C M, 15 anos, sexo feminino, branca, estudante, foi encaminhada ao reumatologista com hipótese diagnóstica de artrite idiopática juvenil (AIJ) pauciarticular. Apresentava, há um ano, dor no ombro D, que melhorava com o uso de anti-inflamatório não-esteroidal (AINE) em dois dias. Teve nesse período de cinco a seis destes episódios que duravam poucos dias. Negava outras queixas articulares ou sistêmicas. Trazia exames normais ou negativos: hemograma, VHS, proteína C reativa, fator reumatoide, sedimento de urina. O FAN era positivo 1/80, pontilhado fino. Trazia Ressonância Magnética do ombro indicativa de sinovite glenoumeral com derrame articular com conteúdo expansivo de tecidos moles na bursa subescapular, segundo o laudo, podendo corresponder a pannus. Como história e exame físico não eram compatíveis com AIJ, foi realizada outra RM que mostrou aumento da lesão já descrita. Foi então encaminhada à artroscopia para biópsia, que revelou SVNP. Durante o procedimento, foi realizada sinovectomia, e uma nova RM feita após nove meses mostrou ausência de sinovite. A SVNP do ombro é incomum e a sinovectomia foi curativa nesse caso.

Chronic monoarthritis demand an investigation of inflammatory diseases, such as rheumatoid arthritis (RA), infectious diseases like tuberculosis; and other diseases that cause synovitis and joint effusion, such as pigmented villonodular synovitis (PVNS), synovial hemangioma, synovial osteochondromatosis and arborescence lipoma. We report the case of a young patient with chronic right shoulder monoarthritis, who's magnetic resonance imaging (MRI) showed synovitis. Arthroscopy was performed and the biopsy revealed PVNS. CASE REPORT: J C M, 15 years-old, female, Caucasian, student. She was sent to a Rheumatologist along with a diagnosis of juvenile idiopathic arthritis (JIA). The patient presented, for one year, a mild pain of insidious onset in her right shoulder, with relief of the symptoms in two days under nonsteroidal anti-inflammatory therapy (NSAIDs). During this year, the patient presented five or six episodes of pain with the same characteristics. No other signs and symptoms were related. The following tests showed normal or negative results:complete blood count, ESR, C-reactive protein, rheumatoid factor and urinalysis. The antinuclear antibody (ANA) was 1/80 speckled pattern. The MRI of the shoulder showed glenohumeral synovitis with joint effusion and soft tissue swelling in the subscapular bursa, which could correspond to pannus. As the medical history and physical examination were not compatible to JIA, a second MRI was performed, which showed an increase of the synovitis. The patient was submitted to an arthroscopy with biopsy and the histopathological examination showed PVNS. A complete synovectomy was performed and a new MRI, nine months later, showed no synovitis. PVNS of the shoulder is uncommon, and synovectomy was curative in this case.

OBJETIVO: analisar as curvas de sobrevida em uma amostra de lúpus eritematoso sistêmico (LES) infanto-juvenil, as variáveis clínicas e laboratoriais e o tipo de tratamento associado ao óbito. MÉTODOS: de uma coorte de 519 pacientes seguidos prospectivamente, 55 foram identificados como tendo LES infanto-juvenil. Análise univariada e regressão de Cox foram utilizadas para determinar as variáveis associadas com a sobrevida nesta coorte. RESULTADOS: o óbito foi identificado em 12 dos pacientes (21,8%) com LES infanto-juvenil. A causa de óbito em freqüência decrescente foi septicemia em 6 (50%), acidente vascular cerebral (AVC) em 4 (33.3%) e insuficiência renal em 2 (16,7%) pacientes. Na análise univariada o sexo masculino, a presença de infecções e o uso de ciclofosfamida oral estiveram associados ao óbito. Na regressão multivariada, somente o sexo masculino influenciou negativamente o tempo de sobrevida (odds ratio 5,8). CONCLUSÕES: em um período de 27 anos o óbito foi observado em 21,8% dos pacientes. Embora infecções tenham sido causa de morte em metade desses pacientes, a sobrevida não estava associada à presença de infecções ou à insuficiência renal, mas ao fato de o paciente ser do sexo masculino. Prestar maior atenção aos meninos com LES, com diagnóstico, tratamento e seguimento adequados pode influenciar o prognóstico nesses casos.

OBJECTIVE: To analyze clinical, laboratory, serological and treatment factors associated with death in a childhood onset childhood systemic lupus erythematosus (SLE) population. METHODS: 55 patients out of 519 prospectively followed-up cohorts were identified as having childhood onset SLE in the State University of Campinas. Univariate analysis and Cox regression model were used to determinate the variables associated with death in this cohort. RESULTS: Death occurred in 12 patients (21.8%), caused by sepsis in 6 (50%), stroke in 4 (33.3%), and renal insufficiency in two (16.7%) cases. In the univariate analysis, male sex, infection and the use of cyclophosphamide were associated with death. In the multivariate regression, only male sex was related to death (odds ratio = 5.8). CONCLUSIONS: During a follow-up period of 27 years, death was observed in 21.8%. Although infection was directly responsible for half of the deaths, survival was not influenced by the presence of infection or renal insufficiency. Male sex was the only variable that influenced survival in this cohort. A greater attention should be given to boys with SLE in order to improve survival.

Estudos epidemiológicos com análise multivariada de fatores prognósticos em pacientes com lúpus eritematoso sistêmico (LES) são fundamentais para avaliar a sobrevida e demonstrar estratégias de diagnóstico e tratamento. OBJETIVO: analisar os fatores de risco para a mortalidade em uma coorte de 509 pacientes com LES. MÉTODOS: os pacientes foram acompanhados em um hospital terciário, por um período de 27 anos (1974-2001), de acordo com um protocolo previamente padronizado. Inicialmente, foi realizada a análise de sobrevida global até o óbito dos 509 pacientes e, posteriormente, foi verificada a diferença entre as probabilidades de sobrevida global para pacientes com início da doença antes dos 16 anos e após os 16 anos. RESULTADOS: a taxa de sobrevida para os 509 pacientes com LES após 1, 5, 10 e 20 anos foram respectivamente de 96%, 88%, 80% e 75%. Os fatores prognósticos para o óbito dos pacientes com LES foram a ausência de artrite ao diagnóstico (p=0,007; OR=0,45; 95%IC= 0,25-0,8), a ausência do uso de antimaláricos (p=0,0001; OR=0,3; 95%IC=0,2-0,5), a presença de hipertensão arterial (p=0,002; OR=2,2; 95%IC=1,1-4,5), a presença de infecções (p=0,003; OR=2,3; 95%IC=1,3-4,1) e a idade ao diagnóstico menor que 16 anos (p=0,004; OR=2,6; 95%IC=1,4-5,0). CONCLUSÕES: este trabalho mostra uma excelente taxa de sobrevida nesta casuística de 509 pacientes com LES, observando-se proporção de pacientes que sobreviveram após 1, 5, 10 e 20 anos de seguimento, respectivamente, de 96%, 88%, 80% e 75%, comparável às maiores séries que tratam de sobrevida.

Epidemiological studies using multivariate analysis of risk factors in Systemic Lupus Erythematosus (SLE) patients are essential to determinate survival and to demonstrate diagnosis and treatment strategies. OBJECTIVE: To analyse the risk factors of mortality in 509 SLE patients who were followed over a 27-year period (from 1974 to 2001) according to a standard protocol in a single centre. The first analysis consisted of the survival time from the date of diagnosis of SLE until the last contact or death. The second analysis consisted of the survival time from the date of diagnosis of SLE until the last contact or death of patients whose disease started before 16 years old compared to patients whose disease started after 16 years old. METHODS: The percentage of survival after 1, 5, 10 and 20 years were 96%, 88%, 80% and 75%. The risk factors for death in SLE patients were the absence of arthritis at diagnosis (p = 0.007; OR = 0.45; 95% IC = 0.25-0.8), the absence of chloroquine sulphate prescription (p = 0.0001; OR = 0.3; 95% CI = 0.2-0.5), the presence of hypertension (p = 0.002; OR = 2.2; 95% CI = 1.1-4.5), the presence of infections (p = 0.003; OR = 2.3; 95% CI = 1.3-4.1) and less than 16 years old at diagnosis (p = 0.004; OR = 2.6; 95% CI = 1.4-5.0). CONCLUSIONS: This paper presents an excellent survival in this cohort of 509 SLE patients. The percentage of survival after 1, 5, 10 and 20 years, respectively 96%, 88%, 80% and 75%, was similar to other studies.
