RESUMEN

OBJETIVOS: Quantificar o gasto e estimar a ingestão energética de crianças e adolescentes com bronquiolite obliterante pós-infecciosa e comparar com crianças e adolescentes hígidos. MÉTODOS: Estudo transversal com 72 crianças e adolescentes de 8 a 18 anos. Compararam-se dois grupos de 36 indivíduos - um com diagnóstico de bronquiolite obliterante e outro hígido -, os quais foram pareados pelo sexo, idade e classificação do índice de massa corporal. Para avaliação nutricional, utilizaram-se a antropometria e a composição corporal. O gasto energético foi medido pela calorimetria indireta; o fator atividade, pelo recordatório 24h de atividades físicas, e a ingestão energética, pelos inquéritos alimentares. RESULTADOS: O grupo com bronquiolite obliterante e o grupo-controle apresentaram respectivamente: índice de massa corporal de M=18,9, DP=4,0kg/m² e M=18,8, DP=3,4kg/m²; gasto energético de repouso de M=1717,6, DP=781,5 e M=2019,9, DP=819; gasto energético total de M=2677,5, DP=1514,0kcal/dia e M=3396,1, DP=1557,9kcal/dia; estimativa da ingestão energética de M=2294,1, DP=746,7kcal/dia e M=2116,5, DP=612,1kcal/dia. O gasto energético de repouso (p=0,102) e o gasto energético total (p=0,051) não foram diferentes entre os grupos, mesmo quando ajustados pela massa magra. Não houve diferenças estatisticamente significativas entre o o gasto energético total e o consumo energético no grupo com bronquiolite obliterante (p=0,202). O grupo-controle consumiu menos calorias do que o previsto pelo gasto energético total (p<0,001). CONCLUSÃO: O gasto energético de repouso e o gasto energético total foram semelhantes entre os grupos. A estimativa da ingestão energética dos hígidos foi menor que o gasto energético total. O grupo com bronquiolite obliterante apresentava um balanço energético adequado.


OBJECTIVE: The aim of the study was to determine the energy expenditure and estimate the energy intake of children and adolescents with post-infectious bronchiolitis obliterans and compare them with those of healthy children and adolescents. METHODS: This cross-sectional study included 36 children and adolescents with bronchiolitis obliterans aged 8 to 18 years, and a control group with 36 healthy individuals matched for sex, age and body mass index. Anthropometric data were collected from all individuals. Energy expenditure was determined by indirect calorimetry, activity factor was estimated by a 24-hour record of physical activities, and energy intake was estimated by the 24-hour food recall. RESULTS: Data for the bronchiolitis obliterans and control groups are, respectively: body mass index of M=18.9, SD=4.0kg/m² and M=18.8, SD=3.4kg/m²; resting energy expenditure of M=1717.6, SD=781.5kcal/day and M=2019.9, SD=819kcal/day; total energy expenditure of M=2677.5, SD=1514.0kcal/day and M=3396.1, SD=1557.9kcal/day; estimated energy intake of M=2294.1, SD=746.7kcal/day and M=2116.5, SD=612.1kcal/day. Resting energy expenditure (p=0.102) and total energy expenditure (p=0.051) did not differ between the groups, even when adjusted for lean mass. Total energy expenditure and intake of the bronchiolitis obliterans group did not differ significantly (p=0.202). Energy intake by the control group was lower than expected according to their total energy expenditure (p<0.001). CONCLUSION: The resting energy expenditure and total energy expenditure of the two groups were similar. The estimated energy intake of the control group was lower than their total energy expenditure. The bronchiolitis obliterans group had an appropriate energy balance.

RESUMEN

Introduction: Adenovirus infection is an important cause of pneumonia in Chilean children. Postinfectious Bronchiolitis Obliterans (PIBO) is the most important complication. There are few studies assessing pulmonary function and quality of life in PIBO patients. Objective: The aim of this study is to assess the pulmonary function and the quality of life of patients with PIBO and the correlation between both variables. Methods: 14 children with PIBO in follow up at the pediatric pulmonology outpatient clinic of a public children hospital were included in this study. Study period: April 2009 - April 2010. Pulmonary function was assessed in a medical visit by spirometry, flow/volume curve and intrathoracic gas volume measurement. The following indices were analyzed FVC, FEV1, FEV25-75, FEV1/FVC, RV, TLC, RV and RV/TLC. A survey of a self-administered Quality of Life (PedsQL, version 4.0, Spanish for Chile) was applied at the visit to investigate their global, physical and psychosocial quality of life. The Pearson linear correlation between quality of life and the pulmonary function test parameters was assessed, in the statistical analysis ap value < 0.05 was considered significant. Results: The mean age of our patients was 12.4 (range: 9-19 years-old). The functional alterations were characteristics of an obstructive respiratory disorder in 64.3 percent of the patients. Average pulmonary function test indices showed decreases in FEV1 (75 percent), FEV25-75 (48.8 percent), FEV1/FVC (67.6 percent) with normal value of FVC (93,7 percent) as well as pronounced increases in RV (333.5 percent), TLC (156 percent) and RV/TLC (51.8 percent). Mean change of FEV1 and FEV25-75post-bronchodilator was 11.3 percent and 26.4 percent respectively. Only 14.3 percent of our patients showed normal pulmonary function. The quality of life parameters were in average 58.2 percent of overall quality of life, 58.6 percent of physical quality of life and 57.9 percent of psychosocial ...


Introducción: La infección por adenovirus es una causa importante de neumonía en niños chilenos. La bronquiolitis obliterante (BOPI) es la complicación más importante. Existen pocos estudios donde evalúen la función pulmonar y la calidad de vida de los pacientes con BOPI. Objetivo: Evaluar la función pulmonar y la calidad de vida de los pacientes con BOPI y la correlación entre ambas variables. Métodos: Se incluyeron 14 niños con BOPI en el policlínico de la unidad de broncopulmonar de un hospital público de niños. Período de estudio: abril de 2009-abril de 2010. La función pulmonar se evaluó en una visita médica por espirometría, curva flujo / volumen y la determinación de volumen de gas intratorácico. Los índices analizados fueron los siguientes CVF, VEF1, FEV25-75, VEF1/CVF, VR,CPT, VR y VR / CPT. En la misma visita se realizó una encuesta auto-administrada de Calidad de Vida (PedsQL, versión 4.0, español de Chile) para investigar la calidad de vida global, física y psi-cosocial. Se aplicó la correlación lineal de Pearson entre calidad de vida y los parámetros de función pulmonar. Se consideró estadísticamente significativo unp <0,05. Resultados: La edad media de nuestros pacientes fue de 12,4 (rango: 9-19 años). La alteración funcional característica fue la obstructiva en el 64,3 por ciento de los pacientes. El promedio de los índices de pruebas de función pulmonar mostraron una disminución en VEF1 (75 por ciento), FEV25-75 (48,8 por ciento), VEF1/CVF (67,6 por ciento) con un valor normal de la CVF (93,7 por ciento), así como aumentos pronunciados en VR (333,5 por ciento), CPT (156 por ciento) y VR/CPT (51,8 por ciento). La media del cambio del VEF1 y FEV25-75post-broncodilatador fue 11,3 por ciento y 26,4 por ciento respectivamente. Sólo el 14,3 por ciento mostró una función pulmonar normal. Los parámetros de calidad de vida fueron en promedio 58,2 por ciento de calidad de vida general, 58,6 por ciento de calidad de vida física y el 57,9 por ciento...
