Distributions and drug resistance to bacterial pathogens in children with community acquired pneumonia in Shanghai

Abstract

Objective To investigate the distribution and drug resistance to pathogenic bacterial pathogen in children with community acquired pneumonia (CAP), so as to provide recommendations for clinical rational use of antibiotics. Methods A retrospective analysis was made on the distribution and drug resistance to bacteria in CAP children admitted to Department of Respiration, Shanghai Children′s Medical Center from January 2014 to December 2015. Results There were 463 patients with positive sputum culture, and a total of 496 strains of pathogens were found.There were 273 Galanz negative bacteria, 195 Galanz positive bacteria and 28 other rare bacteria, accounted for 55.04%, 39.31% and 5.65% of the total bacteria, respectively.The main pathogens were Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Klebsiella pneumoniae and Escherichia coli.The highest detection rate of bacteria in 1-12 months children with CAP was Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli; in >12 months children with CAP, the highest detection rate of bacteria was Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus.Both of Streptococcus pneumoniae and Staphylococcus aureus had a high resis-tance to Erythromycin, Clindamycin and Oxacillin.There were 11.00% Streptococcus pneumoniae and 94.74% taphylococcus aureus resistant to Penicillin, while they were not resistant to Vancomycin.Escherichia coli and Klebsiella pneumoniae both showed a high resistance to ampicillin, the second and third generation cephalosporins.Haemophilus influenzae were highly resistant to Compound sulfamethoxazole and Ampicillin.Galanz negative bacteria had the lowest resistance to Piperacillin/Tazobactam and Amikacin. Conclusions The main pathogens of CAP in children were G- bacteria.There were some differences among the isolates at different ages of CAP.Their resistance to very common anti-biotics was very high in children.
