Abstract
Introducción y objetivos: conocer la situación en la que
se encuentran los pacientes con fibrosis quística en relación con sus niveles de vitamina D y su asociación con las
colonizaciones pulmonares crónicas.
Material y métodos: estudio multicéntrico transversal.
Participaron 12 hospitales nacionales. De noviembre a
abril del 2012 al 2014 se incluyeron 377 pacientes con fibrosis quística. Se consideraron insuficientes niveles de
vitamina D < 30 ng/ml. Presentar al menos dos cultivos
positivos en el último año fue considerado un criterio de
colonización crónica.
Resultados: los pacientes tenían una mediana de edad
de 8,9 años (2 meses—20 años). Un 65% presentaban
niveles insuficientes de vitamina D. Se observó una correlación inversa entre edad y niveles de vitamina D
(r = -0,20 p < 0,001). Los diagnosticados por cribado eran
más jóvenes y tenían niveles de vitamina D más altos.
Los niveles de vitamina D presentaron una correlación
inversa con el número de colonizaciones pulmonares
(r = -0,16 p = 0,0015). Ajustando por edad, función pancreática y diagnóstico mediante cribado, la colonización
por S. Aureus en menores de seis años y por Pseudomonas
sp. en los mayores de esa edad, incrementaban el riesgo
de presentar niveles insuficientes de vitamina D: OR 3,17
(IC95% 1,32-7,61) (p=0,010) y OR 3,77 (IC95% 1,37-
10,37)(p = 0,010), respectivamente. Conclusiones: a pesar de una suplementación adecuada, más de la mitad de nuestros pacientes no alcanzan
niveles óptimos de vitamina D. La colonización crónica
por Pseudomonas sp. en escolares y adolescentes y por
S. Aureus en lactantes y preescolares se asocia de forma
independiente con la deficiencia de vitamina D.
Introduction and objectives: evaluate vitamin D status and its association with chronic lung colonisation in Cystic Fibrosis patients. Material and methods: descriptive cross-sectional multicenter study. From November 2012 to April 2014, at 12 national hospitals, 377 patients with Cystic Fibrosis were included. Vitamin D levels < 30 ng/ml were classified as insufficient. Chronic colonisation was considered if they had at least two positive cultures in the past year. Results: the median age was 8.9 years (2 months to 20 years). 65% had insufficient levels of vitamin D. There was an inverse correlation between age and vitamin D levels (r = -0.20 p < 0.001). Those diagnosed by screening, were younger and had higher levels of vitamin D. There was an inverse correlation between the number of colonisations and vitamin D levels (r = -0.16 p = 0.0015). Adjusting for age, pancreatic status and diagnosis by screening, colonization by S. aureus in <6 years and Pseudomonas sp. in > 6 years, increased the risk of insufficient levels of vitamin D: OR 3.17 (95% CI 1.32 to 7.61) (p = 0.010) and OR 3.77 (95% CI 1.37 to 10 , 37) (p = 0.010), respectively. Conclusions: despite adequate supplementation, more than half of our patients did not achieve optimal levels of vitamin D. Regardless of age, diagnosis by screening or pancreatic status, chronic colonization by Pseudomonas sp. in children and adolescents and S. Aureus in infants and preschoolars increases the risk of developing vitamin D deficiency in these patients.
