    Publication . Neto, A; Mourão, AF; Oliveira-Ramos, F; Campanilho-Marques, R; Estanqueiro, P; Salgado, M; Guedes, M; Piotto, D; Emi Aikawa, N; Melo Gomes, J; Cabral, M; Conde, M; Figueira, R; Santos, MJ; Fonseca, JE; Terreri, MT; Canhão, H
    Objective: To investigate the relationship between body mass index (BMI) and disease activity in patients with Juvenile Idiopathic Arthritis (JIA). Methods: Patients with JIA, aged ≤18 years, registered at the Rheumatic Diseases Portuguese Register (Reuma.pt) in Portugal and Brazil were included. Ageand sex-specific BMI percentiles were calculated based on WHO growth standard charts and categorized into underweight (P<3), normal weight (3≤P≤85), overweight (8597). Disease activity was assessed by Juvenile Arthritis Disease Activity Score (JADAS-27). Uni- and multivariable analyses were performed. Results: A total of 275 patients were included. The prevalence of underweight, normal weight, overweight and obesity was 6.9%, 67.3%, 15.3% and 10.5%, respectively. Underweight patients had significantly higher number of active joints (p<0.001), patient’s/parent’s global assessment of disease activity (PGA) (p=0.020), physician’s global assessment of disease activity (PhGA) (p<0.001), erythrocyte sedimentation rate (ESR) (p=0.032) and overall higher JADAS-27 (p<0.001), compared to patients with normal weight, overweight and obesity. In the multivariable regression, normal weight (B=-9.43, p<0.01), overweight (B=-9.30, p=0.01) and obesity (B=-9.12, p=0.01) were significantly associated with lower disease activity compared to underweight, when adjusted for age, gender, country, ethnicity, JIA category and therapies used. The diagnosis of RF- (B=3.65, p=0.006) or RF+ polyarticular JIA (B=5.29, p=0.024), the absence of DMARD therapy (B=5.54, p<0.001) and the use of oral GC (B=4.98, p=0.002) were also associated with higher JADAS-27. Conclusion: We found an independent association between underweight and higher disease activity in patients with JIA. Further studies are needed to understand the underlying mechanisms of this association.

  • Intoxicação por Monóxido de Carbono
    Publication . Conde, A; Alegria, A; Neto, A
    O monóxido de carbono é uma das principais causas de intoxicação, podendo ser letal ou levar a sequelas neuropsicológicas tardias. A intoxicação manifesta-se por sintomas pouco especificos, pelo que o seu diagnóstico exige um elevado índice de suspeição. 0 doseamento de carboxihemoglobina e útil, mas apresenta uma fraca correlação quer com a clínica, quer com o prognóstico. O tratamento baseia-se na oxigenação adequada dos tecidos, não sendo ainda consensuais os critérios para a administração de oxigenoterapia hiperbárica. Fundamental continua a ser o esforço na prevenção desta intoxicação.

  • Morbilidade Respiratória e Exposição a Partículas Inaláveis na Cidade de Lisboa
    Publication . Moreira, S; Silva Santos, C; Tente, H; Nogueira, L; Ferreira, F; Neto, A
    Introdução: Os efeitos adversos das partículas em suspensão na saúde humana expressam-se sob efeitos agudos e crónicos, não existindo nenhum limiar abaixo do qual se considere que a exposição a partículas não origine efeitos na saúde da população. À semelhança de outras capitais europeias, a cidade de Lisboa apresenta elevados níveis de partículas, principalmente nas áreas de maior tráfego. Objectivo: Neste estudo procurou-se analisar os efeitos na saúde humana decorrentes da exposição ambiental a partículas em suspensão na atmosfera (PM10 e PM2.5). Metodologia: O estudo centrou-se nos efeitos das partículas inaláveis na saúde respiratória da população infanto-juvenil residente em Lisboa. Para o efeito, foram caracterizados os níveis de partículas (PM10 e PM2.5) em Lisboa e procedeu-se a uma avaliação da morbilidade respiratória, utilizando métodos indirectos relacionados com a procura e utilização dos serviços de saúde em situação de urgência, tendo como base os atendimentos da Urgência Pediátrica de um Hospital de Lisboa. Resultados: Verificou-se que um terço das urgências pediátricas hospitalares é de natureza respiratória, destacando-se quatro principais patologias: infecção aguda das vias aéreas superiores, infecção aguda das vias aéreas inferiores, asma e pneumonia. Os modelos estatísticos explicativos foram desenvolvidos com vista a aferir as variáveis ambientais mais relevantes para avaliar os impactes da poluição atmosférica por PM na saúde respiratória infantil, identificando-se um desfasamento temporal, de poucos dias, entre as ocorrências de elevadas concentrações de partículas e os efeitos respiratórios. Conclusão: Nestes modelos a temperatura mínima surge como importante variável explicativa, assim como as concentrações de partículas medidas em estações de fundo (mais representativas dos níveis de concentrações de PM de zonas residenciais) em detrimento das estações de tráfego. Foi evidente uma relação entre a zona de residência das crianças com problemas respiratórios atendidas na urgência e as áreas da cidade com maiores níveis de partículas.

  • Portuguese Recommendations for the Use of Biological and Targeted Synthetic Disease-Modifying Antirheumatic Drugs in Patients with Rheumatoid Arthritis - 2020 Update
    Publication . Fernandes, BM; Guimarães, F; Almeida, DE; Neto, A; Tavares-Costa, J; Roxo Ribeiro, A; Quintal, A; Pereira, JP; Silva, L; Nóvoa, TS; Faustino, A; Vaz, C; Khmelinskii, N; Samões, B; Dourado, E; Silva, JL; Barcelos, A; Mariz, E; Guerra, M; Santos, MJ; Silvério-António, M; Teixeira, RL; Romão, VC; Santos, H; Santos-Faria, D; Azevedo, S; Rodrigues, A; Dias, JM; Lopes, C; Pinto, P; Couto, M; Miranda, LC; Bernardo, A; Cruz, M; Teixeira, F; Mourão, AF; Neto, A; Teixeira, V; Cordeiro, A; Barreira, S; Inês, LS; Capela, S; Sepriano, A; Canhão, H; Fonseca, JE; Duarte, C; Bernardes, M
    Objective: To update the recommendations for the treatment of rheumatoid arthritis (RA) with biological and targeted synthetic disease-modifying antirheumatic drugs (bDMARDs and tsDMARDs), endorsed by the Portuguese Society of Rheumatology (SPR). Methods: These treatment recommendations were formulated by Portuguese rheumatologists taking into account previous recommendations, new literature evidence and consensus opinion. At a national meeting, in a virtual format, three of the ten previous recommendations were re-addressed and discussed after a more focused literature review. A first draft of the updated recommendations was elaborated by a team of SPR rheumatologists from the SPR rheumatoid arthritis study group, GEAR. The resulting document circulated among all SPR rheumatologists for discussion and input. The level of agreement with each of all the recommendations was anonymously voted online by all SPR rheumatologists. Results: These recommendations cover general aspects such as shared decision, treatment objectives, systematic assessment of disease activity and burden and its registry in Reuma.pt. Consensus was also achieved regarding specific aspects such as initiation of bDMARDs and tsDMARDs, assessment of treatment response, switching and definition of persistent remission. Conclusion: These recommendations may be used for guidance of treatment with bDMARDs and tsDMARDs in patients with RA. As more evidence becomes available and more therapies are licensed, these recommendations will be updated.

  • Predictive Factors of Relapse After Methotrexate Discontinuation in Juvenile Idiopathic Arthritis Patients With Inactive Disease
    Publication . Azevedo, S; Tavares-Costa, J; Melo, AT; Freitas, R; Cabral, M; Conde, M; Aguiar, F; Neto, A; Mourão, AF; Oliveira-Ramos, F; Santos, MJ; Peixoto, D
    Objective: To identify predictive factors of relapse after discontinuation of Methotrexate (MTX) in Juvenile Idiopathic Arthritis (JIA) patients with inactive disease. Methods: We conducted a prospective multicenter cohort study of patients diagnosed with JIA using real world data from the Portuguese national register database, Reuma.pt. Patients with JIA who have reached JADAS27 inactive disease and discontinued MTX before the age of 18 were evaluated. Results: A total of 1470 patients with JIA were registered in Reuma.pt. Of the 119 bionaive patients who discontinued MTX due to inactive disease, 32.8% have relapsed. Median time of persistence (using the Kaplan-Meier method and log-rank tests) with inactive disease was significantly higher in patients with more than two years of remission before MTX discontinuation and in those who did not use NSAIDs at time of MTX discontinuation. In Cox regression analyses and after adjustment for age at diagnosis, MTX tapering and JIA category, the use of NSAIDs at the time of MTX discontinuation (HR, 1.98 95%CI 1.03-3.82) and remission time of less than two years before suspension (HR, 3.12 95%CI 1.35-7.13) remained associated with relapse. No association was found between JIA category or the regimen of MTX discontinuation and the risk of relapse. Conclusions: In this large cohort we found that the use of NSAIDs at the time of MTX discontinuation was associated with a two times higher likelihood of relapse. In addition, longer duration of remission before MTX withdrawal reduces the chance of relapse in bionaive JIA patients.
