ABSTRACT

ABSTRACT Objective: To evaluate exercise capacity in children and adolescents with post-infectious bronchiolitis obliterans. Data source: This is a systematic review based on data from PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO), and Physiotherapy Evidence Database (PEDro). We used the following search strategy: "Exercise capacity OR Exercise Test OR Physical fitness OR Functional capacity OR Six-minute walk test OR Shuttle walk test OR Cardiopulmonary exercise test AND Bronchiolitis obliterans." We selected studies that evaluated exercise capacity through maximal/submaximal testing in children and adolescents with post-infectious bronchiolitis obliterans, and no other associated disease. We searched articles in English, Portuguese, and Spanish, without restrictions regarding the period of publication. The methodological quality was assessed by the Agency for Healthcare Research and Quality (AHRQ) protocol. Data synthesis: Out of the 81 articles found, only 4 were included in this review. The studies totaled 135 participants (121 with post-infectious bronchiolitis obliterans and 14 healthy), with sample sizes between 14 and 58 subjects. All patients underwent spirometry to evaluate pulmonary function, indicating an obstructive ventilatory pattern. Among them, 3/4 had their physical performance assessed by the six-minute walk test and 2/4 by the cardiopulmonary exercise testing. These test results were compared to those of a control group (1/4) and presented as percentage of predicted and/or in meters (3/4). Lastly, 3/4 of the studies showed reduced exercise capacity in this population. The studies included were classified as having high methodological quality. Conclusions: Findings of the study demonstrate that children and adolescents with post-infectious bronchiolitis obliterans have reduced exercise capacity.


RESUMO Objetivo: Avaliar a capacidade de exercício em crianças e adolescentes com bronquiolite obliterante pós-infeciosa. Fonte de dados: Trata-se de uma revisão sistemática por meio das bases de dados PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO) e Physiotherapy Evidence Database (PEDro). Utilizou-se a seguinte estratégia de busca: "Exercise capacity OR Exercise Test OR Physical fitness OR Functional capacity OR Six minute walk test OR Shuttle walk test OR Cardiopulmonary exercise test AND Bronchiolitis obliterans". Foram selecionados estudos que avaliaram a capacidade de exercício por meio de testes máximos/submáximos em crianças e adolescentes com bronquiolite obliterante pós-infeciosa, sem qualquer outra doença associada. Buscaram-se artigos nos idiomas inglês, português e espanhol e sem restrições quanto ao período de publicação. A qualidade metodológica foi avaliada pelo protocolo da Agency for Health Care Research and Quality (AHRQ). Síntese dos dados: De um total de 81 artigos, apenas 4 foram incluídos nesta revisão. Os estudos totalizaram 135 participantes (121 com bronquiolite obliterante pós-infeciosa e 14 saudáveis), com tamanho amostral entre 14 e 58 sujeitos. Todos avaliaram a função pulmonar por meio da espirometria, observando um padrão ventilatório obstrutivo. Desses, 3/4 avaliaram o desempenho físico pelo teste de caminhada de seis minutos e 2/4 pelo teste de exercício cardiopulmonar. Os resultados desses testes foram comparados a um grupo controle (1/4), bem como apresentados em percentual do previsto e/ou em metros (3/4). Por fim, 3/4 dos estudos demostraram que a capacidade de exercício se encontra reduzida nessa população. Os estudos incluídos foram classificados com alta qualidade metodológica. Conclusões: Os achados do estudo demonstram que crianças e adolescentes com bronquiolite obliterante pós-infeciosa apresentam redução da capacidade de exercício.

ABSTRACT

Summary Swyer-James syndrome is a complication of post-infectious bronchiolitis obliterans that causes inflammation and fibrosis of the bronchial walls. There are two types: asymptomatic, with most cases diagnosed in adults during routine radiological examinations; and symptomatic, most commonly found in children. Here, we report the case of a 6-year-old child with recurrent dyspnea since the age of 3, who showed signs and symptoms of bronchiolitis obliterans and radiological signs of bronchial wall thickening and air trapping. The clinical and radiological findings led to the diagnosis of Swyer-James syndrome. Treatment of this syndrome is intended to reduce the pulmonary lesions and improve the patient's quality of life.


Resumo A síndrome de Swyer-James-Macleod é uma complicação da bronquiolite pós-infecciosa, ocasionando inflamação e fibrose das paredes dos bronquíolos. Pode se manifestar de duas formas: assintomática, sendo a maioria diagnosticada na fase adulta, quando o paciente se submete a exames radiológicos de rotina, e a forma sintomática, que é mais encontrada em crianças. Relatamos um caso de uma criança de 6 anos de idade com crises de dispneia de repetição desde os 3 anos, apresentando sinais e sintomas de bronquiolite obliterante e sinais radiológicos de espessamento brônquico e aprisionamento aéreo. Por meio da clínica e achados radiológicos, foi feito o diagnóstico de síndrome de Swyer-James-Macleod. O tratamento dessa síndrome visa a reduzir as lesões pulmonares e a melhorar a qualidade de vida do paciente.

ABSTRACT

Relata-se o caso de paciente octogenária, com infarto agudo do miocárdio (IAM) em evolução, que desenvolveu quadro inflamatório pulmonar agudo, compatível com diagnóstico de pneumonia em organização secundária ao uso de abciximab intracoronariano, em angioplastia percutânea coronariana (APC). Esse diagnóstico foi firmado por meio de alterações clínicas, radiográficas e tomográficas típicas e pela regressão dessas alterações após terapia com corticosteroide.


This report presents the case of an octogenarian female patient with acute myocardial infarction who developed an acute inflammatory pulmonary condition compatible with a diagnosis of secondary organizing pneumonia after intracoronary abciximab during percutaneous coronary angioplasty. This diagnosis was grounded on typical clinical, radiographic and tomographic alterations and the regression of these alterations after corticoid treatment.

ABSTRACT

OBJETIVO: Descrever a função pulmonar de crianças e adolescentes com bronquiolite obliterante pós-infecciosa (BOPI) e avaliar potenciais fatores de risco para pior função pulmonar. MÉTODOS: A função pulmonar de 77 participantes, com idades de 8-18 anos, foi avaliada por meio de espirometria e pletismografia. Os seguintes parâmetros foram analisados: CVF, VEF1, FEF25-75 por cento, VEF1/CVF, VR, CPT, VR/CPT, volume de gás intratorácico e specific airway resistance (sRaw, resistência específica das vias aéreas). Foi utilizada a regressão de Poisson para investigar os seguintes potenciais fatores de risco para pior função pulmonar: sexo, idade do primeiro sibilo, idade ao diagnóstico, história familiar de asma, exposição ao tabaco, tempo de hospitalização e tempo de ventilação mecânica. RESULTADOS: A idade média foi de 13,5 anos. Houve uma diminuição importante de VEF1 e FEF25-75 por cento, assim como um aumento de VR e sRaw, característicos de doença obstrutiva das vias aéreas. Os parâmetros mais afetados e as médias percentuais dos valores previstos foram VEF1 = 45,9 por cento; FEF25-75 por cento = 21,5 por cento; VR = 281,1 por cento; VR/CPT = 236,2 por cento; e sRaw = 665,3 por cento. Nenhum dos potenciais fatores de risco avaliados apresentou uma associação significativa com pior função pulmonar. CONCLUSÕES: As crianças com BOPI apresentaram um padrão comum de comprometimento grave da função pulmonar, caracterizado por uma obstrução importante das vias aéreas e um expressivo aumento de VR e sRaw. A combinação de medidas espirométricas e pletismográficas pode ser mais útil na avaliação do dano funcional, assim como no acompanhamento desses pacientes. Fatores de riscos conhecidos para doenças respiratórias não parecem estar associados a pior função pulmonar em BOPI.


OBJECTIVE: To describe the pulmonary function in children and adolescents with postinfectious bronchiolitis obliterans (PIBO), as well as to evaluate potential risk factors for severe impairment of pulmonary function. METHODS: The pulmonary function of 77 participants, aged 8-18 years, was assessed by spirometry and plethysmography. The following parameters were analyzed: FVC; FEV1; FEF25-75 percent; FEV1/FVC; RV; TLC; RV/TLC; intrathoracic gas volume; and specific airway resistance (sRaw). We used Poisson regression to investigate the following potential risk factors for severe impairment of pulmonary function: gender; age at first wheeze; age at diagnosis; family history of asthma; tobacco smoke exposure; length of hospital stay; and duration of mechanical ventilation. RESULTS: The mean age was 13.5 years. There were pronounced decreases in FEV1 and FEF25-75 percent, as well as increases in RV and sRaw. These alterations are characteristic of obstructive airway disease. For the parameters that were the most affected, the mean values (percentage of predicted) were as follows: FEV1 = 45.9 percent; FEF25-75 percent = 21.5 percent; RV = 281.1 percent; RV/TLC = 236.2 percent; and sRaw = 665.3 percent. None of the potential risk factors studied showed a significant association with severely impaired pulmonary function. CONCLUSIONS: The patients with PIBO had a common pattern of severe pulmonary function impairment, characterized by marked airway obstruction and pronounced increases in RV and sRaw. The combination of spirometric and plethysmographic measurements can be more useful for assessing functional damage, as well as in the follow-up of these patients, than are either of these techniques used in isolation. Known risk factors for respiratory diseases do not seem to be associated with severely impaired pulmonary function in PIBO.

ABSTRACT

Descreve-se uma apresentação rara de bronquiolite obliterante associada a hemossiderose pulmonar, em paciente de nove anos com sintomas respiratórios persistentes iniciados após episódio de bronquiolite aguda grave aos sete meses. Após o episódio agudo, apresentou sintomas respiratórios persistentes, piorando significativamente aos sete anos, quando começou a apresentar dificuldade respiratória em pequenos esforços. A tomografia computadorizada de tórax demonstrou achados compatíveis com bronquiolite obliterante. A biópsia pulmonar a céu aberto demonstrou numerosos macrófagos corados com hemossiderina, além dos achados compatíveis com bronquiolite obliterante. O diagnóstico de hemossiderose pulmonar pode estar ocasionalmente associado a bronquiolite obliterante em crianças com seqüela pós-viral grave.


In the present report, we describe an unusual presentation of post-infectious bronchiolitis obliterans accompanied by pulmonary hemosiderosis in a nine-year-old boy with persistent respiratory symptoms subsequent to an episode of acute bronchiolitis occurring at the age of seven months. After the episode, the persistent respiratory symptoms worsened significantly, and, by the age of seven, the patient began to have difficulty breathing after minimal exertion. Computed tomography of the chest presented findings consistent with bronchiolitis obliterans. Open lung biopsy revealed numerous hemosiderin-laden macrophages, as well as other findings consistent with bronchiolitis obliterans. Pulmonary hemosiderosis can occasionally be accompanied by bronchiolitis obliterans in children with severe sequelae after an episode of viral infection.

ABSTRACT

A case of inflammatory pseudotumor of the lung occurring in a six-year-old boy is reported with clinicopathologic findings, including its ultrastructure. The patient had had frequent upper respiratory tract infections, and one and half year before the discovery of the lung mass, he suffered from pneumonia of the right lung, which was serologically proven to be a mycoplasma pneumoniae infection. Exploratory thoracotomy revealed a large mediastinal mass that was removed together with the right middle and lower lobes of the lung. The mass arose from the lung with an endobronchial element. Microscopically, the mass was composed of a variety of inflammatory and mesenchymal cells, including plasma cells, histiocytes, lymphocytes, and fibroblast-like spindle cells. Ultrastructurally, the spindle-shaped mesenchymal cells were either fibroblasts or myofibroblasts. At the time of diagnosis of the inflammatory pseudotumor of the lung, the serum titer of antimycoplasma antibody rose again, and the lung parenchyma adjacent to the mass showed interstitial pneumonia with features of bronchiolitis obliterans. The present case suggests that the inflammatory pseudotumor of the lung could be a postinflammatory lesion associated with mycoplasma pneumoniae infection.
