RESUMEN

Takayasu's arteritis (TA) and rheumatic fever are diseases that can start with cardiac features, making the diagnosis difficult. There are reports of association of RF with Takayasu's arteritis beginning with cardiac involvement in pediatric patients. The aim of this study is to report the possible association of RF and TA in patients with cardiac abnormalities. We describe the case of an adolescent initially diagnosed with RF who progressed with changes that allowed making the diagnosis of TA. TA and RF are two important causes of valve involvement that may have systemic manifestations.

RESUMEN

OBJECTIVE: To describe the clinical and angiographic characteristics of Takayasu's arteritis in Brazilian children and adolescents. METHODS: A retrospective data collection was performed in 71 children and adolescents followed in 10 Brazilian reference centers in Pediatric Rheumatology. The evaluation was carried out in three different time points: from onset of symptoms to diagnosis, from the 6th to 12th month of diagnosis, and in the last visit. RESULTS: Of 71 selected patients, 51 (71.8%) were girls. The mean age of onset of symptoms and of time to diagnosis was 9.2 (±4.2) years and 1.2 (±1.4) years, respectively. At the end of the study, 20 patients were in a state of disease activity, 39 in remission and 5 had evolved to death. The most common symptoms in baseline assessment, second evaluation, and final evaluation were, respectively: constitutional, musculoskeletal, and neurological symptoms. A decrease in peripheral pulses was the most frequent cardiovascular signal, and an increase in erythrocyte sedimentation rate was the most frequent laboratory finding in all three evaluation periods. The tuberculin test was positive in 41% of those tested. Stenosis was the most frequent angiographic lesion, abdominal artery was the most affected segment, and angiographic type IV the most frequent. Most (90%) participants were treated with glucocorticoids, 85.9% required another immunosuppressive drug, and 29.6% underwent angioplasty. CONCLUSION: This is the largest study on juvenile-onset Takayasu arteritis, and a high number of patients under the age of 10 years, with predominance of constitutional symptoms early in the disease, was observed.

RESUMO Objetivo: Descrever as características clínicas e angiográficas da arterite de Takayasu em crianças e adolescentes brasileiros. Métodos: Foi feita coleta retrospectiva de dados de 71 crianças e adolescentes acompanhados em 10 centros brasileiros de referência em reumatologia pediátrica. A avaliação foi feita em três tempos: início dos sintomas até o diagnóstico, do 6º ao 12º mês de diagnóstico e última consulta. Resultados: Dos 71 pacientes selecionados, 51 (71,8%) eram meninas. As médias de idade de início dos sintomas e de tempo até diagnóstico foram 9,2 anos (± 4,2) e 1,2 anos (± 1,4), respectivamente. No fim do estudo, 20 pacientes estavam em atividade de doença, 39 em remissão e cinco haviam evoluído a óbito. Os sintomas mais frequentes nas avaliação inicial, segunda avaliação e avaliação final foram, respectivamente, os constitucionais, os musculoesqueléticos e os neurológicos. A redução de pulsos periféricos foi o sinal cardiovascular mais frequente e a elevação da velocidade de hemossedimentação foi o achado laboratorial mais frequente nos três períodos de avaliação. O teste tuberculínico foi reagente em 41%. A estenose foi a lesão angiográfica mais encontrada, a artéria abdominal foi o segmento mais afetado e tipo angiográfico IV o mais frequente. A maioria (90%) fez terapia com glicocorticoides, 85,9% necessitaram de outro imunossupressor e 29,6% foram submetidos à angioplastia. Conclusão: Este é o maior estudo de arterite de Takayasu juvenil e nós observar elevado número de pacientes com idade inferior a 10 anos e a predominância de sintomas constitucionais no início da doença.

RESUMEN

INTRODUCTION: Paediatric rheumatology (PR) is an emerging specialty, practised by a limited number of specialists. Currently, there is neither a record of the profile of rheumatology patients being treated in Brazil nor data on the training of qualified rheumatology professionals in the country. OBJECTIVE: To investigate the profile of PR specialists and services, as well as the characteristics of paediatric patients with rheumatic diseases, for estimating the current state of rheumatology in the state of São Paulo. PATIENTS AND METHODS: In 2010, the scientific department of PR of the Paediatric Society of São Paulo administered a questionnaire that was answered by 24/31 accredited specialists in PR practising in state of São Paulo and by 8/21 institutions that provide PR care. RESULTS: Most (91%) of the surveyed professionals practise in public institutions. Private clinics (28.6%) and public institutions (37.5%) reported not having access to nailfold capillaroscopy, and 50% of the private clinics reported not having access to acupuncture. The average duration of professional practise in PR was 9.4 years, and 67% of the physicians had attended postgraduate programmes. Seven (87.5%) public institutions perform teaching activities, in which new paediatric rheumatologists are trained, and five (62.5%) offer postgraduate programmes. Two-thirds of the surveyed specialists use immunosuppressants and biological agents classified as "restricted use" by the Health Secretariat. The disease most frequently reported was juvenile idiopathic arthritis (29.1-34.5%), followed by juvenile systemic lupus erythematosus (JSLE) (11.6-12.3%) and rheumatic fever (9.1-15.9%). The incidence of vasculitis (including Henoch-Schönlein purpura, Wegener's granulomatosis, and Takayasu's arteritis) and autoinflammatory syndromes was higher in public institutions compared to other institutions (P = 0.03, P = 0.04, P = 0.002, and P < 0.0001, respectively). Patients with JSLE had the highest mortality rate (68% of deaths), mainly due to infection. CONCLUSION: The field of PR in the state of São Paulo has a significant number of specialists with postgraduate degrees who mostly practise at teaching institutions with infrastructures appropriate for the care of high-complexity patients.

RESUMEN

INTRODUÇÃO: A reumatologia pediátrica (RP) é uma especialidade emergente, com número restrito de especialistas, e ainda não conta com uma casuística brasileira sobre o perfil dos pacientes atendidos e as informações sobre a formação de profissionais capacitados. OBJETIVO: Estudar o perfil dos especialistas e dos serviços em RP e as características dos pacientes com doenças reumáticas nessa faixa etária a fim de estimar a situação atual no estado de São Paulo (ESP). PACIENTES E MÉTODOS: No ano de 2010 o departamento científico de RP da Sociedade de Pediatria de São Paulo encaminhou um questionário respondido por 24/31 especialistas com título de especialização em RP que atuam no ESP e por 8/12 instituições com atendimento nesta especialidade. RESULTADOS: A maioria (91%) dos profissionais exerce suas atividades em instituições públicas. Clínicas privadas (28,6%) e instituições (37,5%) relataram não ter acesso ao exame de capilaroscopia e 50% das clínicas privadas não tem acesso à acupuntura. A média de tempo de prática profissional na especialidade foi de 9,4 anos, sendo 67% deles pós-graduados. Sete (87,5%) instituições públicas atuam na área de ensino, formando novos reumatologistas pediátricos. Cinco (62,5%) delas têm pós-graduação. Dois terços dos especialistas utilizam imunossupressores e agentes biológicos de uso restrito pela Secretaria da Saúde. A doença mais atendida foi artrite idiopática juvenil (29,1%-34,5%), seguida de lúpus eritematoso sistêmico juvenil (LESJ) (11,6%-12,3%) e febre reumática (9,1%-15,9%). Vasculites (púrpura de Henoch Schönlein, Wegener, Takayasu) e síndromes autoinflamatórias foram mais incidentes nas instituições públicas (P = 0,03; P = 0,04; P = 0,002 e P < 0,0001, respectivamente). O LESJ foi a doença com maior mortalidade (68% dos óbitos), principalmente por infecção. CONCLUSÃO: A RP no ESP conta com um número expressivo de especialistas pós-graduados, que atuam especialmente em instituições de ensino, com infraestrutura adequada ao atendimento de pacientes de alta complexidade.

RESUMEN

INTRODUÇÃO/OBJETIVOS: Avaliar a prática clínica com relação à verificação do cartão vacinal e à indicação de vacinas específicas em pacientes com doenças reumáticas pediátricas em uso de diferentes drogas, e evidenciar a possível associação entre frequência de vacinação e tempo de prática clínica dos reumatologistas pediátricos do estado de São Paulo. MATERIAL E MÉTODOS: Um questionário foi enviado para os reumatologistas pediátricos do Departamento de Reumatologia da Sociedade de Pediatra de São Paulo. Esse instrumento incluiu questões sobre tempo de prática em Reumatologia Pediátrica, vacinação de pacientes com Lúpus Eritematoso Sistêmico Juvenil (LESJ), artrite idiopática juvenil (AIJ), dermatomiosite juvenil (DMJ) e imunização de acordo com os tratamentos utilizados. RESULTADOS: Cartão de vacinação foi visto por 100 por cento dos profissionais na primeira consulta e por 36 por cento anualmente. Vacinas de agentes vivos não foram recomendadas para pacientes com LESJ, AIJ e DMJ em 44 por cento, 64 por cento e 48 por cento, respectivamente. Os profissionais foram divididos em dois grupos: A (< 15 anos de prática, n = 12) e B (> 16 anos, n = 13). Nenhuma diferença estatística foi observada no uso de vacinas de agentes vivos e vacinas de agentes inativos ou componentes proteicos em relação ao tratamento nos dois grupos (P > 0,05). Além disso, os grupos foram similares em relação à opinião sobre a gravidade de imunossupressão em pacientes com LESJ, AIJ e DMJ com ou sem atividade e a terapêutica utilizada (P > 0,05). CONCLUSÕES: A frequência de vacinação por reumatologistas pediátricos de São Paulo é baixa, especialmente após a primeira consulta, e não é influenciada pelo tempo de prática profissional.

INTRODUCTION/OBJECTIVES: Evaluate clinical practice through assessment of vaccination card and recommendation of specific vaccines in pediatric patients with rheumatic diseases in use of different drugs and reveal the possible association between vaccination frequency and time of the clinical practice of pediatric rheumatologists in the state of São Paulo. MATERIAL AND METHODS: A questionnaire was sent to pediatric rheumatologists of the Departamento de Reumatologia da Sociedade de Pediatria de São Paulo. This instrument included questions about practice time on Pediatric Rheumatology, vaccination of patients with juvenile systemic lupus erythematosus (JSLE), juvenile idiopathic arthritis (JIA), juvenile dermatomyositis (JDM), and immunization according to the treatments used. RESULTS: Vaccination card was seen by 100 percent of the professionals at the first visit and by 36 percent annually. Vaccines of live agents were not recommended for patients with JSLE, JIA, and JDM in 44 percent, 64 percent, and 48 percent, respectively. The professionals were divided into two groups: Group A (< 15 years of practice, n = 12) and B (> 16 years, n = 13). No statistical difference was observed in the use of live agent vaccine and vaccines with inactivated agents or protein components in the two treatment groups (P > 0.05). Moreover, the groups had similar opinion regarding severity of immunosuppression in patients with JSLE, JIA, and JDM (with or without activity) and treatment used (P > 0.05). CONCLUSIONS: The frequency of immunization by pediatric rheumatologists in São Paulo is low, especially after the first visit, and not influenced by time of professional practice.

RESUMEN

INTRODUÇÃO/OBJETIVO: Avaliar a frequência do comprometimento da habilidade verbal e possíveis fatores associados em pacientes portadores de Lúpus Eritematoso Sistêmico Juvenil (LESJ). PACIENTES E MÉTODOS: Estudo transversal de 36 crianças e adolescentes com LESJ, de um grupo de 57 pacientes, do Ambulatório de Reumatologia do Departamento de Pediatria e Clínica Médica da Santa Casa de Misericórdia de São Paulo. Por ocasião do diagnóstico e do estudo, foram analisados aspectos epidemiológicos, clínicos, socioeconômicos e de escolaridade. Os pacientes foram submetidos a testes cognitivos e exames laboratoriais, e foram avaliadas medidas de atividade da doença (SLEDAI) e do dano cumulativo (SLICC-DI) e o tratamento com corticoesteroide. Os pacientes foram submetidos a testes cognitivos (escalas Weschler de inteligência: WISC III e WAISS III), e os resultados foram avaliados de acordo com os aspectos epidemiológicos, clínicos, laboratoriais e terapêuticos. RESULTADOS: A média de idade ao diagnóstico foi de 11,2 ± 2 anos, a idade na época do estudo de 15,4 ± 4,7 anos, com 89 por cento do sexo feminino. Houve predomínio de pacientes da classe socioeconômica C (61,1 por cento). O comprometimento cognitivo detectado nesses pacientes foi frequente (58,3 por cento), sendo o comprometimento da habilidade verbal um dos domínios cognitivos mais constantes. Encontrou-se associação do comprometimento da habilidade verbal com baixa condição socioeconômica e dano cumulativo (P < 0,05), mas não com atividade da doença, presença de autoanticorpos e dose de corticoesteroide (P > 0,05). CONCLUSÕES: Alteração da habilidade verbal é frequente no LESJ e está associada à condição socioeconômica e ao dano cumulativo, devendo ser suspeitada e investigada, principalmente por se tratar de pacientes pediátricos, para que não haja comprometimento da qualidade de vida na fase adulta. Como não está relacionado à atividade da doença ou à presença de autoanticorpos, deve ser sempre avaliado na presença ou não desses fatores. Da mesma forma, deve-se avaliar independentemente das doses de corticoesteroide por não haver associação.

INTRODUCTION/OBJECTIVE: Evaluate the frequency of verbal ability impairment and associated factors in patients with juvenile systemic lupus erythematosus (JSLE). PATIENTS AND METHODS: Cross sectional study of 36 children and adolescents with JSLE of a group of 57 patients at the Clinic of Rheumatology, Department of Pediatrics and Medical Clinic of Santa Casa de Misericórdia de São Paulo. At the time of diagnosis and study, we analyzed the following epidemiological features: clinical, socioeconomic, and educational level. Patients underwent cognitive and laboratory tests and we assessed disease activity (SLEDAI), cumulative damage (SLICC-DI), and treatment with corticosteroids. The patients underwent cognitive tests (Wechsler Intelligence Scales: WISC III and Waiss III), and the results were evaluated according to epidemiological, clinical, laboratory and treatment features. RESULTS: The mean age at diagnosis was 11.2 ± 2 years and at the time of the study the mean age was 15.4 ± 4.7 years. There was predominance of women (89 percent) and of socioeconomic class C patients (61.1 percent). The cognitive impairment found in these patients was frequent (58.3 percent), affecting more often the verbal ability. We found association of verbal ability impairment with low socioeconomic status and cumulative damage (P < 0.05), but not with disease activity, presence of autoantibodies, and dose of corticosteroids (P > 0.05). CONCLUSIONS: Change in verbal ability is frequent in JSLE and is associated with socioeconomic status and cumulative damage, and should be suspected and investigated, particularly in pediatric patients to avoid quality of life impairment in adulthood. As it is not related with disease activity or presence of autoantibodies, it should always be assessed in the presence or absence of these factors. Likewise, the doses of corticosteroids should be independently evaluated.

RESUMEN

Crianças e adolescentes com doenças reumatológicas apresentam maior prevalência de doenças infecciosas quando comparados com a população em geral, em decorrência de atividade da doença, possível deficiência imunológica secundária à própria doença, ou uso de terapia imunossupressora. A vacinação é uma medida eficaz para a redução da morbidade e mortalidade nesses pacientes. O objetivo deste artigo foi realizar um consenso de eficácia e segurança das vacinas em crianças e adolescentes com doenças reumatológicas infantis baseadas em níveis de evidência científica. Imunização passiva para os pacientes e orientações para as pessoas que convivem com doentes imunodeprimidos também foram incluídas. Os 32 pediatras reumatologistas membros do Departamento de Reumatologia da Sociedade de Pediatria de São Paulo (SPSP) e/ou da Comissão de Reumatologia Pediátrica da Sociedade Brasileira de Reumatologia elaboraram o consenso, sendo que alguns desses profissionais estão envolvidos em pesquisas e publicações científicas nesta área. A pesquisa dos termos eficácia e/ou segurança das diferentes vacinas em crianças e adolescentes com doenças reumatológicas foi realizada nas bases de Medline e Scielo, de 1966 até março de 2009, incluindo revisões, estudos controlados e relatos de casos. O grau de recomendação e o nível científico de evidências dos estudos foram classificados em quatro níveis para cada vacina. De um modo geral, as vacinas inativadas e de componentes são seguras nos pacientes com doenças reumatológicas, mesmo em uso de terapias imunossupressoras. Entretanto, vacinas com agentes vivos atenuados são, em geral, contraindicadas para os pacientes imunossuprimidos.

Incidence of infectious diseases is higher in children and adolescents with rheumatic diseases than in the general population due to disease activity, possible immune deficiency secondary to the disease itself, or the use of immunosuppressive drugs. Vaccination is effective in reducing morbidity and mortality in those patients. The objective of this study was to establish an evidence-based consensus on the efficacy and safety of vaccination in children and adolescents with rheumatic diseases. Passive immunization of patients and guidelines for people who live with immunosuppressed patients were also included. The 32 pediatric rheumatologists of the Rheumatology Department of the Pediatrics Society of São Paulo, (SPSP, from the Portuguese), São Paulo, SP, Brazil, and/or the Commission on Pediatrics Rheumatology of the Brazilian Society of Rheumatology are responsible for this consensus; some of those professionals are involved on research and scientific publications in this field. The words efficacy and/or safety of different vaccines in children and adolescents with rheumatologic diseases were searched in Medline and Scielo data bases from 1966 to March 2009, including reviews, controlled studies, and case reports. The degree of recommendation and the scientific evidence of the studies were classified in four levels for each vaccine. As a rule, inactive and protein components vaccines are safe for patients with rheumatologic diseases, even in the presence of immunosuppressive therapy. However, live attenuated vaccines are, in general, contraindicated for immunosuppressed patients.
