[Distribution and drug resistance of pathogens in infected organ donors from donation after the citizen death].
Zhonghua Yi Xue za Zhi [Chinese medical journal] 2018 January 17
Objective: To investigate the distribution and drug resistance of pathogens in infected organ donors from donation after the citizen death (DCD). Methods: Clinical data of 217 DCD donors from January 2013 to June 2017 were retrospectively analyzed.The phlegm, urine, blood and drainage fluid from all of the donors were routinely cultured.The infection rate of the donors, the composition ratio of pathogens and the distribution of specimen sources were observed and the drug resistance was analyzed. Results: Of all the 217 donors, 128 were infected and the infection rate was 59%.A total of 218 pathogens were isolated from these infected donors, including 55.5% (121/218) of gram-negative pathogens, 33.5% (73/218) of gram-positive pathogens followed by 11.0% (24/218) of fungi.The pathogenic specimens were mainly derived from sputum samples (72.5%), followed by urine (15.6%). The mainly two gram-negative pathogens were Klebsiella pneumonia and Acinetobacter baumannii . Klebsiella pneumonia exhibited varying degree of resistance to commonly used antibiotics, whereas susceptible to imipenem and meropenem. Acine - tobacterbaumannii was highly resistant to most of the antibiotics, and the drug resistance rate of imipenem and meropenem was over 60%, displaying a tendency of multi-drug resistance. Staphylococcus aureus, as the mainly gram-positive pathogen, was generally resistant to penicillin and clindamycin, but still sensitive to tovancomycin, teicoplanin and linezolid. Conclusions: DCD donors have a high infection rate, and respiratory infection is most common. Gram-negative pathogens are the primary pathogens causing infection in DCD donors. Klebsiella pneumonia maintain susceptible to imipenem and meropenem, while Acinetobacter baumannii reveals a tendency of multi-drug resistance.Gram-positive pathogens are still sensitive to vancomycin, teicoplanin and linezolid.
