As suas manifestações clínicas principais são denominadas sinais maiores, incluindo a artrite, cardite, coréia, nódulos subcutâneos e eritema marginado. Entre as manifestações denominadas sinais menores estão o aumento do intervalo P-R no eletrocardiograma, febre, provas de fase aguda positivas, como a VHS e a proteína C reativa. A comprovação de infecção recente pelo estreptococo é considerada um critério essencial. A FR é ainda prevalente nos países em desenvolvimento e emergentes, tendo como complicações crônica o dano valvular causado pela cardite. A sua prevenção é realizada com a erradicação do estreptococo na orofaringe, por meio da profilaxia primária com penicilina benzatina e a profilaxia secundária com a manutenção da penicilina benzatina em intervalos de 21 dias, de acordo com a recomendação da OMS. Como a FR pode apresentar seqüelas, impacto social e na qualidade de vida, justifica-se a avaliação do desfecho clínico e as suas manifestações em longo prazo. Examinar a epidemiologia, as características clínicas e o desfecho da FR em uma série de casos, nos últimos 20 anos em uma unidade acadêmica dedicada à reumatologia pediátrica (HC-FMB-UNESP). 178 casos foram identificados no período de 1986 a 2007 e destes, 134 foram revisados de acordo com um protocolo listando as manifestações clínicas e laboratoriais, o uso de medicação, o período de acompanhamento e os episódios de recorrência durante o seguimento para vigilância da profilaxia secundária. Os dados demográficos, assim como as manifestações clínicas, laboratoriais e de desfecho são apresentados por meio de freqüência para os dados categóricos e pela estatística descritiva para variáveis contínuas.

The main clinical features are named major signs as arthritis, carditis, chorea, subcutaneous nodules and erythema marginatum. Among other features, there are the minor signs as increased P-R interval on electrocardiogram (ECG), fever and acute phase reaction measured by erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP). Evidence of previous streptococcal infection is considered a core criteria. RF is highly prevalent in developing countries, where the main complication is damaged heart valves due to carditis. Prophylaxis is called primary when long-acting benzyl penicilin is administered for the first time after diagnosis and it is called secondary prophylaxis for maintenance treatment with long-acting benzyl penicilin every 3 weeks, according to the WHO guidelines. As RF may result in heart damage with both quality of life and social impact, it is valuable to assess its long term outcome. To examine epidemiology , clinical features and outcome of RF in a paediatric case series, seen in an academic unit dedicated to paediatric rheumatology (HC-FMB-UNESP) during the last 20 years. 178 cases were identified from 1986 to 2007, of those 134 were fully revised according to a standardized protocol checking for clinical and laboratorial features, treatment, follow up and acute RF relapse during follow up for prophylaxis surveillance. Demographics, clinical and laboratorial features as well as outcome data are reported by frequency for categorical variables. Continuous variables are presented by descriptive statistics. The probability of carditis, valve damage and RF relapses were examined by survival analysis with actuarial survival plots. Of 134 revised cases, age at onset was from 4 to 13.8 years, follow up duration was from 1.1 to 16.9 years mean 6.8 SD (3.6) and median... (Complete abstract click electronic access below)

Rheumatic heart disease is an inflammatory heart disease that affects millions of people around the world. Especially high rates of the disease can be found in Oceania, including the island nation of Samoa. Genetic studies of immune response genes have provided insight into a possible genetic link to increased susceptibility to rheumatic heart disease, including the genes that code for the toll-like receptor (TLR) protein family. One of the functions of TLR proteins is to recognize the presence of bacteria via identification of bacterial flagella. My evaluation of a Samoan family identified a variant in the TLR-5 gene that would inhibit this ability. However, further study showed this variant to not be statistically significant in relation to rheumatic heart disease susceptibility. My contribution to a regional genome-wide association study of Oceania resulted in the discovery of a variant in the IGHV4-61 gene affecting the ability of antibodies to properly bind to bacterial antigens. This variant was associated with a 1.4-fold increased risk of rheumatic heart disease development. The success of this study warrants further investigation of the IGHV4-61 variant in other populations and illustrates the benefits of utilizing a genome-wide association study to study rheumatic heart disease.

Métodos: Os itens e escalas do Childhood Health Assessment Questionnaire (CHAQ) e Child Health Questionnaire (CHQ-PF-50) foram compilados em um estudo transversal, durante a fase ativa ou inativa da FR; comparados com valores normativos populacionais, e de acordo com o estado de atividade ou inatividade da doença. Resultados: Cento e sete questionários foram analisados. Dezessete casos foram avaliados durante a fase aguda, seja durante o primeiro surto ou recorrência, e 90 em inatividade. A média de idade e duração média de doença na avaliação foram de 14,4 l 3,9 e 0,7l1,7 anos para casos em atividade e 12, 5l 4,3 e 5,5l4,1 anos para casos em inatividade, respectivamente. Todos os domínios e o índice de incapacidade física do CHAQ, os índices Físico e o Psico-social do CHQ-PF-50, assim como as escalas de dor e bem-estar global, apresentaram diferença significante na pontuação quando comparados com a da população de referência. A comparação destes índices e escalas, entre os casos de FR em atividade e inatividade, também apresentou diferença significante, resultando em maior incapacidade e pior avaliação do estado de saúde, com exceção da escala de dor e do Indice Psicosocial. Conclusões: A FR tem impacto nos índices de saúde física e psico-social, comparados com a população saudável. As propriedades psicométricas de ambos os instrumentos, CHAQ e CHQ-PF50, foram consideradas adequadas revelando validade de face e discriminativa. / Abstract: Objetive: The purpose of this study was to assess self-reported measures of physical and psychosocial well-being in Rheumatic Fever patients (RF). Methods: The Childhood Health Assessment Questionnaire (CHAQ) and the Child Health Questionnaire (CHQ-PF-50) itens and scales were compiled in clinic for a cross sectional study, during RF active and inactive phases, and compared to population normative values, as well as according to disease activity status. Results: One hundred and seven questionnaires were analysed. Seventeen cases were assessed during active phase, either during the first attack or relapse, and 90 during inactive phase. Mean age and mean disease duration at completion was 14,4 l 3,9 and 0,7l1,7 years for active cases and 12, 5l 4,3 and 5,5+4,1 years for inactive cases, respectively. The CHAQ and CHQ domains scoring, CHAQ-Disability Index, CHQPhysical - Psychosocial scores, and both pain and overall well-being scales, presented significant difference in patients with rheumatic fever compared to population normative values. The active and inactive RF cases values were compared as well, resulting in worse function and health, during active phase compared to inactive, except for pain-VAS and CHQ- Psychosocial Scores. Conclusions: RF causes impact on physical and psychosocial health scoring compared to the general population. Both tools, CHAQ and CHQ-PF50 have shown good psychometric properties with proper face and discriminant validity. / Mestre
