Aim of the work: The purpose of this study was to assess vitamin D concentrations in children with lower respiratory tract infections.
Patients and Methods:After obtaining approval of the ethics committee, a prospective case control study was conducted in pediatric department, Damietta Faculty of Medicine, Al-Azhar University Hospital on children with lower respiratory tract infections and comparing 25-hydroxyvitamin D level between them and normal matched control from December 2018 to September 2019 include 140 children, Group A: 70 cases children had lower respiratory tract infections [LRTIs] either isolated pneumonia or associated with sepsis. Group B: matched with 70 healthy subjects.
Results: There was significant reduction of vitamin D among study group children when compared to control group [13.68±5.50 s 40.64±4.76 ng/dl respectively]. There was no significant association between type of infection and vitamin D levels. However, all children with bronchitis had sufficient vitamin D levels.
