Objectives: The study aim was to describe clinical and paraclinical characteristics of Chlamydia trachomatis pneumonia in children under 6 months of age at Vietnam National Children’s Hospital.
Methods: This cross-sectional study included 71 cases of C. trachomatis pneumonia in Respiratory Department, Vietnam National Children’s Hospital between 1 September 2017 and 31 August 2018.
Results: Important features of C. trachomatis pneumonia in children under 6 months of age include persistent cough, nasopharyngitis, conjunctivitis, history of vaginal birth, mother’s history of vaginosis during pregnancy. Absolute eosinophil counts greater than 300/mm3 may suggest C. trachomatis pneumonia.
Conclusion: Clinical manifestations of pneumonia due to C. trachomatis pneumonia are persistent cough, nasopharyngitis, conjunctivitis, mother’s history of vaginosis during pregnancy. A higher than 300 eosinophils/mm3 is strongly associated with C. trachomatis pneumonia.
