The Relationship Between Serum Vitamin D Level and Severity of Bronchiolitis in Infants Being Referred to in Bandar Abbas Children’s Hospital, Iran

Background: The present study aimed to investigate the relationship between the serum vitamin D level and the severity of bronchiolitis in infants.Materials and Methods: The population of this descriptive-analytical study included all infants within the age range of ۱ month to ۲۴ months old with bronchiolitis hospitalized in Bandar Abbas children’s hospital in ۲۰۱۸-۲۰۱۹. According to the exclusion and inclusion criteria, patients were entered in the study and diagnosed with bronchiolitis by a pediatric infectious disease specialist. Then, their serum levels of vitamin D were measured as well.Results: Of the ۸۵ patients, ۶۲.۴% and ۳۷.۶% were males and females, respectively. The mean serum level of vitamin D was ۲۹.۷۴ ± ۱۳.۴۴ ng/mL. In addition, the mean age in groups with mild-, moderate-, and severe-intensity was ۹.۲۷ ± ۴.۵۲ months, ۵.۱۲ ± ۳.۹۵ months, and ۳.۱۶ ± ۱.۱۶ months (P < ۰.۰۰۱), respectively. Further, the Spearman’s correlation between age and serum vitamin D levels was r = ۰.۰۵ (P < ۰.۰۰۱). Based on the results, there was a statistically significant difference between the mean age in the two study groups (P < ۰.۰۰۱). Finally, a statistically significant association was found between the severity of bronchiolitis and vitamin D status (P = ۰.۰۰۷).Conclusion: According to the results of the present study, more than half of the infants admitted to the diagnosis of bronchiolitis had insufficient serum levels of vitamin D. There was also a significant association between the severity of bronchiolitis and serum vitamin D levels.
