Abstract
Objective To study the relationship between vitamin D deficiency rickets and recurrent respiratory tract infection in infants. Methods Totally 236 cases of recurrent respiratory tract infection were chosen in observation group, and 108 infants receiving physical examination were randomly selected in control group.The incidence of vitamin D deficiency rickets was observed in two groups, and serum 25 (OH)D3 and alkaline phosphatase (AKP) concentrations were compared between two groups.Results In the observation group rickets were found in 69 cases (29.2%) and vitamin D sub clinical state in 48 cases (20.3%), while in the control group there were 16 cases (14.8%) and 29 cases (27.4%), respectively.The incidence in two groups was significantly different (χ2 =11.22,P <0.05). Compared with the control group, serum 25 ( OH) D3 , AKP, IgG and IgA concentrations in the observation group were lower but AKP concentration was higher with significant difference (t value was 14.18, 8.74, 16.73, 1.67 and 4.11, respectively, all P<0.05). Conclusion Infants vitamin D deficiency rickets is closely related with recurrent respiratory tract infection.Preventive supplementation of vitamin D is an effective way to improve infant immune function and prevent recurrent respiratory tract infection.关键词
