Abstract Objective To explore the effect of vitamin A (VitA) supplementation on T lymphocytes levels in peripheral blood of children with iron deficiency anemia and repeated lower respiratory infection. Methods A total of 116 patients with iron deficiency anemia and repeated lower respiratory infection who admitted to Hebei Children’s Hospital from January 2017 to June 2019 were enrolled. They were divided into the observation group and the control group by random number table method, with 58 cases in each group. The control group was given routine anti-infection treatment. On this basis, the observation group was given VitA supplementation treatment. The changes in levels of anemia status indexes, T lymphocyte subsets and immunoglobulins before and after treatment were compared between the two groups. The effective rate, cough time, white blood cell count recovery normal time and hospital stay time were recorded and compared between the two groups. Results The effective rate in the observation group was higher than that in the control group (P < 0.05). After 6 months of treatment, the levels of hemoglobin, mean corpuscular volume, content of mean corpuscular hemoglobin and mean corpuscular-hemoglobin concentration in both groups were higher than those before treatment, and the observation group was higher than the control group (P < 0.05). After 6 months of treatment, the levels of CD3+, CD4+ and CD4+/CD8+ in the two groups were higher than those before treatment, while the levels of CD8+ were lower than those before treatment. The levels of CD3+, CD4+ and CD4+/CD8+ in the observation group were higher than those in the control group, while the levels of CD8+ were lower than those in the control group (P < 0.05). After 6 months of treatment, IgM, IgA and IgG levels in the two groups were higher than those before treatment and the observation group was higher than the control group (P < 0.05). The duration of cough, the time of white blood cell count recovery normal and hospital stay time in the observation group were shorter than those in the control group (all P < 0.05). Conclusion Anti-infection treatment assisted by VitA can effectively improve anemia and low immune function in children with iron deficiency anemia and repeated lower respiratory infection, shorten treatment process and accelerate their recovery.
