Abstract:
Objective To explore the clinical features of children with Burkholderia gladioli (B. gladioli) bloodstream infection and the drug susceptibility of B. gladioli. Methods The clinical data of 63 children with B. gladioli bloodstream infection admitted to Wuhan Children’s Hospital, Tongji Medical College of Huazhong University of Science and Technology from Jan. 2015 to Jan. 2016 were retrospectively analyzed, and 81 children with non-bacterial infectious diseases in the same period were enrolled as controls. The C-reactive protein (CRP) level, procalcitonin (PCT) level and white blood cell (WBC) counts of children were compared between the two groups. B. gladioli was isolated from the blood samples of children and cultured for preliminary identifying by Phoenixtm100 automatic microorganism identification instrument and confirming by MALDI-TOP MS mass spectrometer. The in vitro antimicrobial susceptibility testing of B. gladioli were performed by Kirby-Bauer method. Results The children infected with B. gladioli were mainly infants, with 52 cases (82.54%) being three years old or below. All cases had serious underlying diseases, including bronchitis, pneumonia and leukemia. Compared with the control group, the PCT level, CRP level, and WBC counts in the children of the B. gladioli group were significantly increased (all P<0.05). According to the drug susceptibility criteria of Pseudomonas aeruginosa, the isolated B. gladioli was highly sensitive to amikacin, gentamycin, tetracycline, minocycline, cotrimoxazole, ciprofloxacin, levofloxacin, imipenem, meropenem, cefepime, piperacillin, piperacillin/tazobactam and cefoperazone/sulbactam, but had low resistance to chloramphenicol and high resistance to ceftazidime and aztreonam. Conclusion Children infected with B. gladioli are mainly infants aged≤3 years old, with low immunity and poor resistance. Blood culture and CRP level, PCT level and WBC counts can be used as diagnostic indicators of disease outcomes. Piperacillin/tazobactam and cefoperazone/sulbactam should be the first selected drugs for the treatment of children with B. gladioli bloodstream infection.
