Abstract :

Background: Pneumonia accounts for 10% of all hospitalizations for children less than 5 years old, increasing healthcare costs, morbidity (30-35%), and mortality (7-13%). Recurrent pneumonia occurs in 7-15% of children with pneumonia. Immunodeficiency may contribute to recurrent pneumonia in children. There has been no prior research about the prevalence of immunodeficiency in Vietnamese children with recurrent pneumonia. Methods: Descriptive study of 80 children aged 6 months to <5 years with recurrent pneumonia (>2 episodes in a single year or >3 episodes ever, with radiographic clearing between occurrences) admitted to the VNCH Emergency Department from 9/2015-8/2017. Children with known immunodeficiency, immunosuppressive therapy, asthma, chronic lung disease or congenital heart disease were excluded. Patients with radiographic and clinically diagnosed recurrent pneumonia had quantitative assays of serum immunoglobulins, IgG subclasses, and T, B and NK lymphocytes. Results: Mean chronologic age of 12.8+8.3 SD months; 60% were male; 11.2% were premature. Mean number of prior pneumonia episodes was 3.4+1.7 SD. On admission, medians for weight and height were 8+2.2kgs. Of the 80 patients, the following immunoglobulin deficiencies were noted: (3.8%), IgM (3.8%), IgG (2.5%) IgG1 (5%), IgG2 (1.2%), IgG3 (7.5%), IgG4 (11.2%). Other causes of recurrent pneumonia were airway abnormalities (6.2%), aspiration syndromes (11.2%) and gastroesophageal reflux (7.5%). Conclusion: Immunodeficiency is an important cause of recurrent pneumonia in Vietnamese children. Assessment of children with recurrent pneumonia can facilitate diagnosing underlying primary immunodeficiency, thereby decreasing mortality and morbidity
