Abstract：Objective To investigate the difference in serum 25(OH)D level between children with bloodstream infection and healthy children. Methods A case-control study was conducted among 60 children with bloodstream infection who were hospitalized between January 2010 and December 2013 and had positive results of two blood cultures. Meanwhile, 60 aged-matched healthy children who underwent physical examination during the same period of time were enrolled as the healthy control group. Chemiluminescence was applied to measure the serum 25(OH)D level, and the constituent ratios of children with different serum 25(OH)D levels were compared between the two groups. Results The bloodstream infection group had a significantly lower serum 25(OH)D level than the healthy control group (PPPConclusions Vitamin D insufficiency prevails among children, and children with bloodstream infection have a significantly lower serum 25(OH) D level than healthy children.
