OBJECTIVE: To investigate the correlation of serum vitamin A, D, and E levels with a recurrent respiratory infection (RRI) in children.
PATIENTS AND METHODS: The medical records of 422 children with RRI (a study group) in Cangzhou Central Hospital from January 2015 to December 2018 were retrospectively analyzed (the study group was divided into an active group and a stable group). Further 100 healthy children who underwent physical examination at the same time were enrolled as a control group. High-performance liquid chromatography (HPLC) was used to determine vitamin A, D, and E levels, so as to analyze their differences between the groups.
RESULTS: Vitamin A, D, and E in the active and stable groups were significantly lower than those in the control group (p < 0.001); in the active group they were significantly lower than those in the stable group (p < 0.001). According to partial correlation analysis, in children with active RRI, vitamin A was respectively positively correlated with vitamin D (r=0.945, p < 0.001), and vitamin E (r=0.988, p < 0.001). Moreover, vitamin E was positively correlated with vitamin D (r=0.959, p < 0.001).
CONCLUSIONS: The deficiency of vitamin A, D, and E is positively correlated with the disease activity of children with RRI. Therefore, the supplement of vitamin A, D, and E through dietary adjustment is beneficial to the rehabilitation of the children.
