Community-Acquired Pneumonia in Children
Abstract
BACKGROUND
Community-acquired pneumonia is an important cause of morbidity in developed countries and an important cause of morbidity and mortality in developing countries. Prompt diagnosis and appropriate treatment are very important.
OBJECTIVE
To provide an update on the evaluation, diagnosis, and treatment of community-acquired pneumonia in children.
METHODS
A PubMed search was completed in Clinical Queries using the key term "communityacquired pneumonia". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. Patents were searched using the key term "community-acquired pneumonia" from www.google.com/patents, http://espacenet.com, and www. freepatentsonline.com.
RESULTS
Generally, viruses, notably respiratory syncytial virus, are the most common cause of community- acquired pneumonia in children younger than 5 years. Streptococcus pneumoniae is the most common bacterial cause across all age groups. Other important bacterial causes in children younger than 5 years include Haemophilus influenzae, Streptococcus pyogenes, Staphylococcus aureus, and Moraxella catarrhalis. In children 5 years or older, in addition to S. pneumoniae, other important bacterial causes include Mycoplasma pneumoniae and Chlamydophila pneumonia. In the majority of cases, bacterial and viral pneumonia cannot be reliably distinguished from each other on clinical grounds. In practice, most children with pneumonia are treated…
