The role of Mycoplasma pneumoniae in children with community-acquired pneumonia / 中国医师进修杂志

ABSTRACT

Objective:To explore the role of Mycoplasma pneumoniae (MP) in hospitalized children with community-acquired pneumonia (CAP) in Suzhou.Methods:Pathogen data of 2 367 patients with bronchiolitis, bronchopneumonia, lobar pneumonia, and interstitial pneumonia were retrospectively analyzed from January 2017 to December 2018 in Children′s Hospital of Soochow University. The detected pathogens were MP, respiratory syncytial virus (RSV), adenovirus (Adv), influenza A, B, parainfluenza virus (PIV) 1, 2 and 3, human metapneumovirus (hMPV), boca virus (HBoV) and bacteria.Results:The most common pathogen of bronchiolitis was RSV (34.9%, 249/713), followed by MP (15.8%, 113/713) and hMPV (11.4%, 85/713). The most common pathogen of bronchial pneumonia was Streptococcus pneumoniae (Sp, 14.8%, 180/1 220), followed by RSV (13.1%, 160/1 220) and MP (10.2%, 124/1 220). The most common pathogen of lobar pneumonia was MP (47.8%, 141/295), followed by Sp(12.9%, 38/295). The most common pathogen of interstitial pneumonia was MP (35.3%, 49/139), followed by RSV (23.0%, 32/139) and Adv (6.5%, 9/139). Compared with non-MP infections, children with MP infections were older, and had higher percentage of fever and less shortness of breath. The adjusted OR(95% CI) was 2.4 (1.1-3.5), 5.1 (3.2-10.4) and 0.2 (0.0-0.4), respectively. Conclusions:MP is the most common pathogen of lobar pneumonia and interstitial pneumonia and the second most common cause of bronchiolitis. MP infections are usually associated with older age, higher percentage of fever and less shortness of breath.
