Health-related quality of life in patients with bronchiolitis obliterans / Qualidade de vida relacionada à saúde em pacientes com bronquiolite obliterante

Abstract Objective: To evaluate the overall health-related quality of life in patients with bronchiolitis obliterans. Methods: Participants with a diagnosis of post-infectious bronchiolitis obliterans, who were being followed-up at two specialized outpatient clinics of Pediatric Pulmonology in Porto Alegre, Brazil, and controls aged between 8 and 17 years, of both genders, were included in the study. Controls were paired by gender, age, and socioeconomic level in relation to the group of participants with post-infectious bronchiolitis obliterans. The version of the Pediatric Quality of Life Inventory (PedsQ) tool validated for Brazil was applied for the assessment of Health-related Quality of Life, through an interview. The comparison of the Health-related Quality of Life means between the groups was performed using Student's t-test for independent samples and the chi-squared test, for categorical variables. Results: 34 patients diagnosed with post-infectious bronchiolitis obliterans and 34 controls participated in the study. The mean age of the children included in the study was 11.2 ± 2.5 years, and 49 (72%) of them were males. The groups showed no significant differences in relation to these variables. The quality of life score was significantly and clinically lower in the post-infectious bronchiolitis obliterans group when compared with controls in the health (72.36 ± 15.6, 81.06 ± 16.4, p = 0.031) and school domains (62.34 ± 20.7, 72.94 ± 21.3, p = 0.043), as well as in the total score (69.53 ± 14.9, 78.02 ± 14.8, p = 0.024), respectively. Conclusion: Patients with post-infectious bronchiolitis obliterans presented lower health-related quality of life scores when compared with healthy individuals in the total score and in the health and school domains.

Resumo Objetivo: Avaliar a qualidade de vida relacionada à saúde geral em participantes com bronquiolite obliterante. Métodos: Foram incluídos no estudo participantes com diagnóstico de bronquiolite obliterante pós-infecciosa que estavam em acompanhamento em dois ambulatórios especializados de pneumologia pediátrica em Porto Alegre, Brasil e controles, entre 8 e 17 anos, de ambos os sexos. Os controles foram pareados por sexo, idade e nível socioeconômico em relação ao grupo de participantes com bronquiolite obliterante pós-infecciosa. Para avaliação da Qualidade de Vida Relacionada à Saúde geral foi aplicado a versão validada para o Brasil do instrumento PedsQL (Pediatric Quality of Life Inventory), por meio de entrevista. A comparação entre as médias da Qualidade de Vida Relacionada à Saúde entre os grupos foi realizada mediante o teste t para amostras independentes e para as variáveis categóricas por teste qui-quadrado. Resultados: Participaram do estudo 34 pacientes com diagnóstico de bronquiolite obliterante pós-infecciosa e 34 controles. A média da idade das crianças incluídas foi de 11,2 ± 2,5 anos e 49 (72%) deles eram do sexo masculino. Os grupos não apresentaram diferenças significativas em relação a essas variáveis. O escore de qualidade de vida foi significativamente e clinicamente menor no grupo bronquiolite obliterante pós-infecciosa em comparação com o controle nos domínios saúde: (72,36 ± 15,6; 81,06 ± 16,4; p = 0,031); escolar: (62,34 ± 20,7; 72,94 ± 21,3; p = 0,043) e no escore total (69,53 ± 14,9; 78,02 ± 14,8, p = 0,024), respectivamente. Conclusão: Os pacientes com bronquiolite obliterante pós-infecciosa apresentam escores de qualidade de vida relacionados à saúde menor do que indivíduos saudáveis no escore total e nos domínios saúde e escolares.
