Abstract

Objective: To describe the clinical and laboratory characteristics and to identify factors associated with the duration of hospitalization among children with Haemophilus influenzae pneumonia treated at the Department of Pediatric Respiratory Medicine, Xanh Pon General Hospital, from 2025 to 2026.

Methods: A cross-sectional descriptive study was conducted.

Participants: A total of 86 children diagnosed with community-acquired pneumonia caused by Haemophilus influenzae who were treated at the Department of Pediatric Respiratory Medicine, Xanh Pon General Hospital, from December 2025 to April 2026.

Results: The mean age was 16.2 ± 10.2 months, with a male-to-female ratio of approximately 4:3. Among the study participants, 52.3% had received Hib vaccination. The most common clinical finding was abnormal breath sounds on lung auscultation, observed in 98.8% of children. Respiratory distress was observed in 12.8% of cases. Diffuse nodular opacities were the predominant radiographic finding, accounting for 74.4% of cases. Laboratory investigations showed elevated C-reactive protein (CRP) levels in 60.5% of children and leukocytosis in 73.2%. The mean length of hospital stay was 7.7 ± 2.0 days.

Conclusion: Haemophilus influenzae pneumonia in children occurred predominantly in those older than 12 months. The most prominent clinical manifestations were productive cough and abnormal breath sounds on lung auscultation, while diffuse pulmonary lesions were the predominant radiographic finding. Treatment outcomes were favorable, with 100% of children showing clinical improvement or recovery.
