Abstract

Post-infectious bronchiolitis obliterans (PIBO) is a small airways disease characterized by fixed airflow limitation. Therefore, inhaled bronchodilators and corticosteroids are not recommended as maintenance therapy options. The management of PIBO currently consists only of close monitoring of affected patients, aimed at the prevention and early treatment of pulmonary infections. In recent years, there has been an increase in the incidence of PIBO in the pediatric population. Patients with PIBO are characterized by a progressive decline in lung function, accompanied by a decrease in overall functional capacity. Here, we report the case of a relatively young man diagnosed with PIBO and followed for three years. After short- and long-term therapy with an inhaled corticosteroid/long-acting 2 agonist combination, together with an inhaled long-acting antimuscarinic, the patient showed relevant improvement of airway obstruction that had been irreversible at the time of the bronchodilator test. The lung function of the patient worsened when he interrupted the triple inhaled therapy. In addition, a 3-week pulmonary rehabilitation program markedly improved his physical performance. RESUMO A bronquiolite obliterante pós-infecciosa (BOPI) é uma doença das pequenas vias aéreas caracterizada por limitação fixa do fluxo aéreo. Portanto, os broncodilatadores e os corticosteroides inalatórios não são recomendados como opções de terapia de manutenção. Atualmente, o manejo da BOPI consiste apenas de um acompanhamento rigoroso dos pacientes afetados, visando à prevenção e ao tratamento precoce de infecções pulmonares. A incidência de BOPI tem aumentado na população pediátrica nos últimos anos. Os pacientes com BOPI caracterizam-se por um declínio progressivo da função pulmonar, associado a uma diminuição da capacidade funcional global. Relatamos aqui o caso de um homem relativamente jovem diagnosticado com BOPI, acompanhado por três anos. Após terapia de curto e de longo prazo com uma combinação de corticosteroide/2-agonista de longa duração inalatórios, associada a um agente antimuscarínico de longa duração inalatório, o paciente apresentou uma melhora relevante da obstrução das vias aéreas, a qual fora irreversível durante o teste de broncodilatação. A função pulmonar do paciente piorou quando ele interrompeu a terapia inalatória tripla. Além disso, um programa de reabilitação pulmonar de três semanas significativamente melhorou seu desempenho físico.
