ABSTRACT

La bronquiolitis obliterante (BO) es un síndrome clínico poco frecuente en niños, caracterizado por la obstrucción crónica al flujo de aire asociado a cambios inflamatorios y distintos grados de fibrosis en la vía aérea pequeña. Si bien existen muchas etiologías, la causa mas frecuente se asocia a infeccionesrespiratorias virales, principalmente adenovirus. No existe un consenso para establecer su diagnóstico; sin embargo, se considera un espectro de síntomas persistentes asociados a un patrón en mosaico, bronquiectasias y atelectasias persistentes. El rol de la biopsia pulmonar ha sido cuestionado por subajo rendimiento, invasividad y complicaciones. No existe un tratamiento específico por lo que elmanejo es soporte. Probablemente la mejor estrategia constituya el empleo de antibióticos en forma agresiva, soporte kinésico y nutricional constante y una precoz rehabilitación pulmonar. Estas guías clínicas representan un esfuerzo multidisciplinario, basado en evidencias actuales para brindarherramientas prácticas para el diagnóstico y cuidado de niños y adolescentes con BO post infecciosa.

ABSTRACT

OBJECTIVE: Undernutrition is a frequent complication in patients with cystic fibrosis (CF). Elevated energy requirements have been found to be 4% to 33% higher than in controls in some studies. Whether or not this is caused by a primary defect or energy metabolism is still a matter of controversy. To this end, we assessed energy expenditure, nutrition status, and body composition of clinically stable CF outpatients. METHODS: Fifteen clinically stable CF patients, ages 2 to 15 y, were paired with 15 healthy control children. Measurements consisted of anthropometry and body composition. Plasma tocopherol, retinol, and hair zinc content were measured. Resting energy expenditure was determined by indirect calorimetry. Physical activity and dietary intake were recorded by recall methods. RESULTS: Two children were nutritionally at risk according to the weight/height index, eight were normal, three were overweight, and two were obese. Body composition was similar in both groups. Zinc, tocopherol, and retinol levels were low in three, two, and three patients, respectively. Resting energy expenditures were 4.7 MJ/d (1127 +/- 220 kcal/d) in CF children and 4.63 MJ/d (1108 +/- 191 kcal/d) in control children (P = not significant). Physical activity level was sedentary in 86.6% of CF patients; the rest had a light physical activity pattern. Energy intake represented 141% of the estimated daily energy expenditure. CONCLUSIONS: Non-oxygen-dependent CF children, without acute respiratory infection, had resting energy expenditures comparable to those of matched controls. Total energy expenditure was similar to or slightly lower than that in healthy children. Dietary recommendations for CF patients need to be reassessed.
