ABSTRACT
Objective To compare the early clinical efficacy of renal transplantation between extended criteria donor (ECD) and standard criteria donor (SCD). Methods Clinical data of 85 recipients undergoing renal transplantation from donation after cardiac death (DCD) were retrospectively analyzed. According to the types of donors, all recipients were divided into the ECD group (n=31) and SCD group (n=54). The level of serum creatinine (Scr), incidence of early complications and clinical prognosis within 3 months after renal transplantation were compared between 2 groups. Results No statistical significance was observed in the levels of Scr within 1 month after renal transplantation between the ECD group and SCD group (all P>0.05). At postoperative 60 and 90 d, the level of Scr in the ECD group was (189±97) and (175± 69) μmol/L respectively, significantly higher than (142±49) and (135±41) μmol/L in the SCD group (P=0.005 and 0.002). In the ECD group and SCD group, the incidence of acute rejection (AR) was 6% and 15%, the incidence of delayed graft function (DGF) was 23% and 19%, the incidence of pulmonary infection was 10% and 6%, the incidence of other early complications was 32% and 15%, respectively, no statistical significance was identified (all P>0.05). In the ECD group and SCD group, the survival rate of the recipient was 97% and 94%, the survival rate of the renal was 84% and 91%, no statistical significance was identified (all P>0.05). Conclusions Compared with the SCD, renal transplantation from ECD can achieve equivalent early clinical efficacy. In the present condition of serious deficiency of donor kidney, the application of ECD can enlarge the supply of the donor kidney.
ABSTRACT
Objective To investigate the clinical characteristics, prevention and treatment of multi-drug resistant organisms (MDROs) infection early after renal transplantation from donation after citizen's death. Methods Clinical data of 166 patients undergoing allogeneic renal transplantation and regular follow-up in Xijing Hospital from November 2011 to September 2016 were retrospectively analyzed. General conditions were statistically compared between the recipients undergoing renal transplantation from donation after cardiac death (DCD) and their counterparts receiving living related donor renal transplantation. The incidence of MDROs infection, onset time, course of diseases, complications, infection site and etiological type were observed. The therapeutic methods and clinical prognosis were summarized. Results The incidence of MDROs infection early after renal transplantation in the recipients undergoing DCD renal transplantation was 14%, significantly higher than 2% in those receiving living related donor renal transplantation, and 13% and 2% for the incidence of delayed graft function with statistical significance (both P<0.05). The incidence of renal graft loss was 8%and 2%, and 5% and 1% for the mortality rate without statistical significance between two groups (both P>0.05). MDROs infection occurred in 11 patients after DCD renal transplantation. The most common infection site was urinary system(n=6) and the most prevalent pathogenic bacterium was Escherichia coli (n=4). All patients infected with MDROs were treated with a sufficient dosage of effective antibiotics according to the outcomes of bacterial culture and drug sensitivity test. Eight patients obtained favorable clinical prognosis, one underwent nephrectomy and two died. Conclusions The incidence of MDROs infection early after DCD renal transplantation is higher than that after living related-donor renal transplantation. Strict donor screening, early detection, intimate monitoring and timely treatment can effectively reduce the risk of MDROs and enhance clinical prognosis.
ABSTRACT
Objective To evaluate the effect of hypothermia status in the donors upon the renal graft function after renal transplantation from donation after citizen's death. Methods Thirty-six eligible donors were randomly divided into the normal temperature (body temperature 36.5-37.5 ℃ , n=19) and hypothermia groups (body temperature 34.0-35.0 ℃ , n=17). The matched recipients undergoing renal transplantation were also assigned into the normal temperature (n=38) and hypothermia groups (n=34). Perioperative conditions of the donors and recipients were compared between two groups. And postoperative renal graft function of the recipients were statistically compared between two groups, including the incidence of delayed graft function (DGF) and primary nonfunction (PNF). Results No statistical significance was identified in the perioperative amount of urine volume, serum creatinine (Scr), systolic blood pressure, saturation oxygen, warm ischemia time and cold ischemia time of the donors between two groups (all P>0.05). No statistical significance was noted in terms of the operation time, intraoperative mean blood glucose and intraoperative mean arterial pressure of the recipients between two groups (all P>0.05). Postoperative incidence of DGF of the recipients in the hypothermia group was 6%, significantly lower than that in the normal temperature group (24%) (χ2=4.393, P=0.036). Postoperative incidence of PNF of the recipients was 3% in both the hypothermia and normal temperature groups with no statistical significance (χ2=0.000, P=1). Conclusions The hypothermia status of the donors can significantly reduce the incidence of DGF, whereas exerts no evident effect upon the incidence of PNF in the recipients.
