A clinical analysis on strengthening prevention strategies for DCD donor fungal infection / 中华器官移植杂志

ABSTRACT

Objective To analyze the clinical effects of the diverse prevention strategies on donation after citizen's death (DCD) donor fungal infection.Methods A retrospective study was performed on the clinical data of the antifungal preventive scheme to 261 DCD donors from January 2015 to August 2015 (the first period) and September 2015 to December 2016 (the second period) in Tongji Hospital.During the first period,the donors were administrated by ICU doctors and the antifungal agents were not applied as routine.The processes of organ procurement and trim were in accordance with the past experience.During the second period,the donor maintenance was reinforced,including antifungal preventive scheme,aseptic manipulation of organ procurement and rinsing and immersing allografts with broad-spectrum antibiotics or diluting povidone-iodine solutions during organ trim.Microbial culture specimens were performed in 1 574 samples including blood samples,perfusion fluids and arterial tissues and the pathogen distribution at the different periods was identified.Result In the microbial culture specimens of 1 574 samples,907 strains of pathogens were detected,including 799 strains of bacteria and 108 strains of fungi.The positive rate of fungi was 12.0％ (108/907) of all pathogens,and 17.3％ (108/626) of fungal cultures specimens.The fungi positive rate in the second period (13.6％,59/433) was significantly lower than that in the first period (25.4％,49/193,P＜ 0.05).Conclusion It is essential to reduce the incidence of donor fungal infection by increasing the microbial cultures and antifungal preventive scheme.And it is necessary that the organ procurement organization team enhances the risk awareness of donor-derived fungal infection and improves the aseptic manipulation of organ procurement.Additionally,rinsing and immersing allografts with broad-spectrum antibiotics or diluting povidone-iodine solutions may be a better option for preventing the donor-derived fungal infection during the allograft trim.
