Abstract
OBJECTIVE: To investigate the effects of vitamin D drops on immune function in children with recurrent respiratory tract infections (RRTI). METHODS: The clinical data of 119 children with RRTI in our hospital were retrospectively retrieved, and they were divided into group A (n=59, receiving routine treatment) and group B (n=60, receiving vitamin D drops) based on their treatment modality. The clinical efficacy, symptom disappearance time, immune function index, insulin-like growth factor (IGF-1), 25-hydroxyvitamin D3 [25-(OH)D3], serum y-interferon (INF-y), and the number of episodes of respiratory tract infections were compared between the two groups. RESULTS: The total effective rate of treatment in group B was 96.67%, which was significantly higher than 71.19% in group A (P<0.05). Children in group B had shorter time to disappearance of lung rales, cough, and fever than group A (P<0.05). Group B had higher IgA, IgG, and IgM levels, higher CD4+, CD3+ levels and lower CD8+ levels as well as higher IGF-1, 25-(OH)D3, INF-y levels, and fewer respiratory infections after treatment than group A (P<0.05). CONCLUSION: Vitamin D drops are effective in the treatment of children with RRTI, which is beneficial to the improvement of clinical symptoms and immune function. AJTR
