Abstract:
Objective To investigate the distribution characteristics of pathogenic bacteria in infectious donors from organ donation after citizen's death and preventive strategies for renal transplant recipients. Methods Clinical data of 412 donors and 803 recipients from organ donation after citizen's death were retrospectively analyzed. All donors underwent culture of airway secretions, urine, blood and renal lavage fluid. The incidence rate of infection, distribution and composition ratio of pathogenic bacteria of donors from organ donation after citizen's death were observed. The scores of all donors were evaluated according to the length of intensive care unit (ICU) stay for donors, the situation of abdominal trauma and the results of body fluid culture, etc. According to the score, the recipients received different infection prevention regimes. The incidence rate of donor-derived infection (DDI) and clinical prognosis of the recipients were analyzed. Results A total of 243 donors were diagnosed with infection in 412 donors from organ donation after citizen's death with an infection rate of 59.0%. In total, 456 strains of pathogenic bacteria were isolated, mainly derived from the airway secretions (71.7%). Gram-negative bacteria dominantly consisted of Klebsiella pneumoniae and acinetobacter baumannii. Gram-positive bacteria mainly included staphylococcus aureus and fungus mainly included yeast-type fungus. Three recipients (kidneys from 2 donors respectively) developed DDI with an incidence rate of 0.4%. Conclusions The infection rate of donors from organ donation after citizen's death is relatively high. It is effective to prevent the incidence of DDI by grading the risk of infection of donors and adopting rational preventive plan according to the score.
