RESUMO
Objective:To explore the clinical efficacy of treating external iliac artery dissection in renal transplantation by artificial vascular replacement.Methods:Four sudden intraoperative cases of external iliac artery dissection were selected.After removing vascular sutures, intimal arterial peeling blocked external iliac artery( n=3)and transplanted renal artery( n=1). Artificial vascular replacement of external iliac artery was performed using artificial vessels made from puffed polytetrafluoride ethylene(ePTFE). Secondary perfusion was performed in four transplanted kidneys for anastomosing with internal iliac artery. Results:One patient regained normal renal function within 1 week post-operation.Two cases had delayed graft function.Another case had delayed graft function plus acute rejection.After hemodialysis, renal function normalized at 2-3 weeks post-operation.During a follow-up period of(0.5-5.0)years, transplanted kidney function remained stable, blood supply, skin temperature and movement of operated lower extremities normalized.Conclusions:The incidence of vascular dissection of external iliac artery is not high during renal transplantation.However, the disease has a rapid and dangerous progression.The consequences of delayed intervention are quite serious.Treating external iliac artery dissection with renal transplantation may achieve satisfactory clinical outcomes.
RESUMO
Objective:To establish risk stratifying criteria for acute rejection(AR)after kidney transplantation(KT)through analyzing the preoperative risk factors of KT recipients from deceased donor(DD).Methods:A retrospective study is conducted for 1 382 KT recipients of DD kidney at First Affiliated Hospital of Xi'an Jiaotong University from January 2015 to December 2020.According to the presence or absence of AR within 1 year post-KT, they are divided into two groups of acute rejection(group AR, 115 cases)and non-rejection(group non-AR, 1 267 cases). Clinical data of two groups are examined by univariate and multivariate analyses for determining the risk factors of AR and a scoring standard is established on the basis of regression coefficients.They are divided into three groups of low-risk(907 cases), middle-risk(450 cases)and high-risk(25 cases)according to the scoring results and the incidence of AR is compared among different scoring groups.Results:Univariate analysis indicates that donor age(AR, 793 cases; non-AR, 474 cases, P=0.033), age difference between recipients and donors≥25 years(AR, 63 cases; non-AR; 315 cases; P<0.001), recipient panel-reactive antibodies(PRA)plus donor-specific antibody(DSA)(+ )(AR, 96 cases; non-AR, 1 169 cases, P=0.002), donor kidney cold ischemic time≥12h(AR, 81 cases; non-AR, 1 064 cases, P<0.001), donor/recipient HLA mismatch≥3(AR, 70 cases; non-AR, 984 cases, P<0.001)and expanded criteria donor(ECD)(AR, 50 cases; non-AR, 790 cases, P<0.001)are high risk factors for AR(all P<0.05). Variables with statistical significance during univariate analysis are included for multivariate analysis.Five variables are finally determined, including age difference between recipients and donors≥25 years(β=0.61, P=0.006), PRA+ DSA(+ )(β=0.74, P=0.008), donor kidney cold ischemic time≥12 h(β=0.74, P<0.001), HLA mismatch(≥3)(β=0.81, P<0.001)and ECD(β=0.82, P<0.001). Score for each risk factor is calculated according to the relevant regression coefficient and scoring standard formulate on the basis of the above five risk factors with a total score of 36.With an overall incidence of AR at 8.32%(115/1 382), the incidence of AR is 4.3%, 14.7% and 40.0% in low/middle/high-risk group and the difference is statistically significant.It hints that immune risk stratification can effectively determine the risk of postoperative AR for KT recipients.The incidence of AR is significantly higher in middle/high-risk group than that in low-risk group ( P<0.001). Conclusions:For recipients with middle/high immune risk, intensity and dose of immunosuppressants should be appropriately boosted during preoperative induction and maintenance period.And the occurrences of AR and infection should be dynamically monitored.
RESUMO
BACKGROUND@#Delayed graft function (DGF) is the main cause of renal function failure after kidney transplantation. This study aims at investigating the value of hypothermic machine perfusion (HMP) parameters combined with perfusate biomarkers on predicting DGF and the time of renal function recovery after deceased donor (DD) kidney transplantation.@*METHODS@#HMP parameters, perfusate biomarkers and baseline characteristics of 113 DD kidney transplantations from January 1, 2019 to August 31, 2019 in the First Affiliated Hospital of Xi'an Jiaotong University were retrospectively analyzed using univariate and multivariate logistic regression analysis.@*RESULTS@#In this study, the DGF incidence was 17.7% (20/113); The multivariate logistic regression results showed that terminal resistance (OR: 1.879, 95% CI 1.145-3.56) and glutathione S-transferase (GST)(OR = 1.62, 95% CI 1.23-2.46) were risk factors for DGF; The Cox model analysis indicated that terminal resistance was an independent hazard factor for renal function recovery time (HR = 0.823, 95% CI 0.735-0.981). The model combining terminal resistance and GST (AUC = 0.888, 95% CI: 0.842-0.933) significantly improved the DGF predictability compared with the use of terminal resistance (AUC = 0.756, 95% CI 0.693-0.818) or GST alone (AUC = 0.729, 95% CI 0.591-0.806).@*CONCLUSION@#According to the factors analyzed in this study, the combination of HMP parameters and perfusate biomarkers displays a potent DGF predictive value.

Objective:To explore the clinical data of acute rejection in kidney transplant recipients of different ages with elderly donor kidneys.Methods:During January 2012 and June 2020, a retrospective review was conducted for clinical data of 298 recipients undergoing kidney transplantation from elderly donors aged ≥60 years after citizen's death.According to the age, recipients were divided into group A(age<30 yr, 59 cases), group B(30~39 yr, 125 cases), group C(40~49 yr, 83 cases)and group D(age≥50 yr, 31 cases). The incidence of acute rejection(AR)was analyzed.Also based upon age difference between donors and recipients, they were divided into two groups of(30~39 yr)and (40~49 yr)and the occurrence of AR was recorded.Results:The incidence of AR within 1 year post-transplantation in groups A, B, C, and D were 15.3%(9/59), 8.8%(11/125), 7.2%(6/83) and 3.2%(1/31)respectively.The incidence of AR in age difference≥25 yr group(12.5%)and age difference <25 yr group(5.3%) had significant difference( P<0.05). The proportion and absolute value of peripheral blood lymphocytes in each group at 1 week/month post-transplantation had significant difference( P<0.05). No significant difference was observed in serum level of creatinine(SCr), the incidence of pulmonary infection and urinary tract infection or the survival rate of recipients and transplanted kidneys in each group within 1 year post-transplantation among four groups( P>0.05). Conclusions:Elderly donor kidneys can obtain better transplant outcomes in kidney transplant recipients of different ages.As the age of recipients decreases, AR shows an upward trend.Clinicians should pay more attention to the prevention and treatment of AR in recipients with large age difference between donors and recipients.
RESUMO
Objective:To explore the prognostic utility of LifePort perfusion parameters plus perfusate biomarkers for predicting delayed graft function(DGF)and recovery time during deceased donor kidney transplantation(KT).Methods:From January 1, 2019 to August 31, 2019, retrospective analysis was performed for clinical data of 113 KT recipients. Based upon whether or not DGF occurred within 3 months, they were divided into two groups of DGF group(20 cases)and non-DGF (93 cases). Two groups were compared using LifePort perfusion parameters, biomarker concentrations, incidence of DGF and kidney recovery time. Statistical analysis was performed.Results:The incidence of DGF was 17.7%(20/113); Multivariate Logistic regression results indicated that terminal resistance(OR 1.879, 95% CI 1.145~3.56)and glutathione S-transferase(GST)(OR 1.62, 95% CI 1.23~2.46)were independent risk factors for DGF; Cox hazard model revealed that terminal resistance was a risk factor for recovery time of renal function(HR=0.823, 95% CI 0.735~0.981). The model combining terminal resistance and GST(AUC=0.888, 95% CI 0.842~0.933)significantly improved the predictive efficacy for DGF as compared with using terminal resistance(AUC=0.756, 95% CI 0.693~0.818)or GST alone(AUC=0.729, 95% CI 0.591~0.806).Conclusions:Combining LifePort perfusion parameters and fluid biomarkers can improve the predictive utility of DGF.
RESUMO
【Objective】 To establish an effective method for acquiring bone marrow-derived dendritic cells (DCs) from BALB/C mice in vitro and to establish a reservoir of DC precursor cells. 【Methods】 CD117+ hematopoietic stem cells (HSCs) were isolated and purified from bone marrow of BALB/C mice by immunomagnetic beads separation system (MACS), and then amplified in vitro with mouse stem cell factor (SCF) and interleukin-3 (IL-3). HSC was induced to differentiate into DCs by adding granulocyte-macrophage colony-stimulating factor (rmGM-CSF) and IL-4. Different cytokines (tumor necrosis factor-alpha or IL-10) were added to control the maturity of dendritic cells. Then the morphology (electron microscopy), surface molecular markers (FACS method) and cytokine secretion level (ELISA method) were identified. 【Results】 ① The purity of CD117 + HSC isolated and purified by MACS system was over 95%. ② SCF plus IL-3 could effectively stimulate HSC amplification. ③ The morphology of mature DC (mDC) and immature DC (imDC) was significantly different under light and scanning electron microscopy. ④ In the expressions of surface markers CD40, CD80, CD86, I-A/I-E, there were significant differences between imDC group and mDC group (P<0.01). ⑤ After LPS stimulation, the secretion of IL-12 in imDC group did not change significantly (P=0.064), while the secretion of IL-12 in mDC group increased significantly (P=0.009). LPS and TNF-α had a synergistic effect in stimulating DC maturation. 【Conclusion】 Specific combinations of cytokines can effectively induce the differentiation of bone marrow HSCs into DCs in BALB/C mice, and can control the maturity of DCs. This study makes it possible to use gene modified dendritic cells in GD immunotherapy.
RESUMO
Objective:To explore the efficacy and safety of low-dose valganciclovir for preventing CMV infection after renal transplantation.Methods:Patients undergoing the first renal transplantation from January 2015 to January 2017 were selected. Recipients were divided into two groups according to anti-CMV prophylactic strategy. Recipients in test group (valganciclovir group, n=85) received oral valganciclovir 450 mg once daily and those in control group (ganciclovir group, n=81) had oral ganciclovir 1g thrice daily. Both drugs were prescribed within 10 days after transplantation and maintained for 3 months. Dose adjustments were based upon renal function. All recipients were followed up for 12 months posttransplantation. CMV-DNA, renal function, blood routine and liver function were regularly monitored. The incidence of CMV infection/disease, the median time to CMV infection onset, the incidence of opportunistic infections (OI) and acute rejection, graft or recipient survival and drug safety were evaluated.Results:A total of 166 renal recipients were admitted. Fewer recipients in test group (12, 14.1 %) than in control group (26, 32.1 %) had CMV infection ( P=0.006). The median time to CMV infection onset was longer in test group than in control group: 140.5 days (interquartile range [IQR]: 77.3-198.5 days) versus 47.5 days (IQR: 36.8-67.8 days) respectively ( P=0.014). The CMV disease rate was lower in test group ( P=0.080). The incidence of OI decreased significantly in test group (10.6 % vs 21.0 %, P=0.037). No patients in test group suffered allograft loss while 6 recipients (7.4 %) in control group ( P=0.032). Other adverse and side effects of both regimens were comparable. Conclusions:Low-dose valganciclovir regimen is both safe and efficacious in preventing CMV infection among kidney transplant recipients during the first year posttransplantation.
RESUMO
Objective To analyze the prediction efficiency of scoring models at home and abroad on delayed graft function (DGF) after renal transplantation in China. Methods The clinical data of 112 donors and 220 recipients undergoing renal transplantation were prospectively analyzed. The DGF predicted by KDRI model, Jeldres model, and model of our center was compared with actual DGF incidence of renal transplant recipients. The prediction efficiency of each model was analyzed. The predictive accuracy was compared by the area under curve (AUC) of receiver operating characteristic (ROC) curve. Results The DGF incidence of 220 renal transplant recipients was 14.1% (31/220). DGF prediction using KDRI model showed that 41 cases were high risk donors, the AUC was 0.57, the sensitivity was 0.37, the specificity was 0.66, and the positive predictive value was 22%. DGF prediction using Jedres model showed that 22 cases were high risk recipients, the AUC was 0.56, the sensitivity was 0.13, the specificity was 0.92 and the positive predictive value was 20%. DGF prediction using the model of our center showed that 25 cases were high risk donors, the AUC was 0.80, the sensitivity was 0.53, the specificity was 0.84, the positive predictive value was 40%. Conclusions Compared with the KDRI and Jedres models, the prediction model of our center has higher AUC and sensitivity with a better prediction efficiency on DGF. Therefore, it is a suitable evaluation system of donors from donation after citizen's death in Chinese.
RESUMO
Objective To compare the clinical efficacy of different T lymphocyte polyclonal antibodies in renal transplantation from donor kidney of organ donation after citizen's death. Methods Clinical data of 691 donors and recipients undergoing renal transplantation from donor kidney of organ donation after citizen's death were retrospectively analyzed. According to different T lymphocyte polyclonal antibodies used for induction, all recipients were divided into the rabbit anti human T lymphocyte immunoglobulin (rALG) group (n=414) and rabbit anti human thymocyte immunoglobulin (rATG) group (n=277). The recovery of renal graft function in recipients of the two groups were collected, including the incidence of delayed graft function (DGF) and acute rejection (AR), and the changes of serum creatinine level after renal transplantation. The 1-year survival rate of the recipients and renal grafts was collected. The incidence of adverse effects within 1 year after operation was calculated. According to the DGF risk score of donors, all recipients were divided into 5 groups. The use proportion of rALG and rATG in the recipients of each group was calculated. Results The incidence of DGF in the recipients of rALG and rATG groups was 14.5% (60/414) and 11.9% (33/277), respectively. The duration of DGF in the recipients of rALG and rATG groups was (7±4) d and (12±7) d respectively, with no statistically significant difference between two groups (P > 0.05). The incidence of AR in the rALG group was 7.5% (31/414), significantly higher than 4.0% (11/277) in the rATG group (P < 0.05). The serum creatinine levels of recipients within 6 months after renal transplantation tended to gradually decline in both groups. In renal transplantation for donor kidney with a DGF risk score of 0-15, the use proportion of rALG was significantly higher than that of rATG. However, the use proportion of rATG was significantly higher than that of rALG in renal transplantation for donor kidney with a DGF risk score over 16 (P < 0.05). The 1-year survival rates of the recipients and renal grafts in the rALG and rATG groups were 99.8% and 99.6%, 98.1% and 98.2%, respectively. There was no significant difference between two groups (both P > 0.05). The incidence of acute pulmonary edema and leukopenia in the recipients of rATG group was significantly higher than that in the rALG group (both P < 0.05). Conclusions Both rALG and rATG can effectively reduce the incidence of DGF and AR and achieve good clinical efficacy after renal transplantation from donor kidney of organ donation after citizen's death. The incidence of leukopenia and acute pulmonary edema induced by rATG is higher than that by rALG in the renal transplant recipients.
RESUMO
Acute kidney injury (AKI) is often associated with organ donation and renal transplantation, which leads to an increase of fatality rate, hospitalization time and hospitalization costs. In recent years, studies have shown that ferroptosis is closely related to AKI, but the exact molecular biological mechanism has not been clarified, which need more research. In this article, the role of ferroptosis in AKI was reviewed from the aspects of ferroptosis related biomarkers and biological reactions, in order to find a new possible direction for the prevention and treatmentof AKI.
RESUMO
Objective To evaluate the clinical effect of hypothermic machine perfusion (HMP) in the storage of renal grafts from deceased donor (DD) with high-risk delayed graft function (DGF). Methods Clinical data of 52 donors with high-risk DGF were collected in this prospective randomized controlled study. Two renal grafts from each donor were randomly divided into the HMP group (n=52) and static cold storage (SCS) group (n=52). In the HMP group, the renal grafts were stored by LifePort under HMP, whereas the renal grafts in the SCS group were preserved in University of Wisconsin solution (UW solution). The incidence of DGF and primary nonfunction (PNF) after renal transplantation was statistically compared between two groups. The recovery of renal graft function, the survival rates of the recipients and renal grafts within postoperative 1 year were observed in two groups. Results The incidence of DGF in the HMP group was 4%(2/52), significantly lower than 17% (9/52) in the SCS group (P < 0.05). No PNF was reported in the HMP group and 1 case of PND was noted in the SCS group, the difference was not statistically significant (P > 0.05). The recovery time of graft function of the recipients in the HMP and SCS groups were (7.2±0.6) d and (7.7±1.0) d with no statistical significance (P > 0.05). In the HMP group, the urine volume of the recipients on the day of operation, postoperative 1 and2 d was significantly larger than that in the SCS group (all P < 0.05). In the HMP group, the levels of serum creatinine at each time point after operation were significantly lower than those in the SCS group (all P < 0.05). The 1-year survival rates of the recipient and kidney were 98.1%, 92.3% and 100%, 96.2% in the HMP and SCS groups with no statistical significance (all P > 0.05). Conclusions HMP can significantly reduce the incidence of DGF after renal transplantation from DD with high-risk DGF and promote the early recovery of graft function.
RESUMO
Objective To analyze the relationship of donor kidney histopathology scores with Lifeport parameters and donor grades before kidney transplantation.Methods Retrospective analysis was including 25 cases of organ donation (DCD) donor kidney transplantation from January 2017 to May 2018.The correlation analysis was performed on histopathological data of donor kidney,Lifeport parameters,and donor grades.Histopathological examination was carried out by rapid paraffin method,and the scores were graded according to the Remuzzi standard and acute tubular injury (ATI) degree.The donor grades were based on the standard score of our center.Data were analyzed by SPSS(R) 17.0 software.Results Remuzzi scores were positively correlated with protopathy scores (r =0.546,P =0.005) and hypertension scores of donor scores (r =0.500,P =0.011).Remuzzi scores and Lifeport parameters flow (Flow) and resistance index (RI) were found to be correlated.Remuzzi scores of glomeruli sclerosis (GS),tubule atrophy (TA),interstitial fibrosis (IF),arterial narrow (AN) and Lifeport parameters were also correlated,among which the correlation of AN scores were strongest correlated with Lifeport parameters (Flow:r =0.539,P＜0.001;RI:r =0.497,P =0.001).ATI had a correlation with Lifeport parameters (Flow:r =0.368,P =0.016;RI:r =0.456,P =0.002),which is most relevant to the RI.However,there was no correlation of the donor grades with Lifeport parameters,and ATI (Flow:r=0.216,P =0.169;RI:r=0.06,P =0.707;ATI:r =0.005,P =0.977).Of 50 cases of kidney transplantation,recover time of DGF group was significantly higer than that of nomal recovery group F =14.729,P =0.001);Lifeport flow parameters of normal recovery group were statistically higher than those of other groups (F =3.612,P =0.020).Conclusion Histopathology scores of donors kidney are correlated with protopathy scores,hypertension scores,and Lifeport parameters,and could be used to evaluate the renal quality effectively.In the clinical work,the donor grades,histopathology scores and Lifeport parameters should be combined to evaluate the kidney quality.

RESUMO
Objective Hypothermic machine perfusion may improve the outcome after transplantation of kidney donated after citizen's death (DCD),but few powered prospective studies have been reported,especially in China.The aim is to compare hypothermic machine perfusion (HMP) with simple cold storage (SCS) in Chinese DCD kidney transplantation,which can offer an optimal method for graft storage with better graft function and survival.Methods 54 kidney pairs from DCD donors were included in this controlled trial in one single center from December 2015 to March 2017.Every two kidneys from each DCD donor wavs randomly assigned to HMP and SCS group.One-year recipient and graft survival rate and endpoints containing the incidence of DGF,the duration of DGF,creatinine reduction ratio (CRR),estimated glomerular filtration rate (Egfr),primary non-function (PNF),acute rejection (AR),toxicity of the immunosuppressive drugs,nosocomial infections and the length of hospital stay were compared between HMP and SCS group.Results One-year recipient survival rate was 98.15 ％ and 96.23％ after DCD transplant in HMP and SCS group,and one-year graft survival rate was 90.74％ and 88.68％,respectively.DGF incidence was 9.62％ in total DCD kidney transplant,8.00％ in HMP group and 11.11％ in SCS group,which was no difference in two groups.22 DCD was from expanded criteria donor (ECD) donation,DGF happened in 15.91％ ECD kidney transplant.However,HMP reduced the incidence of DGF from 27.27％ to 4.55％ after ECD kidney transplant,which was significantly different (x2 =4.247,P =0.039).HMP group acquired significantly lower creatinine level (130.95 ± 46.60) μmol/L than SCS group (181.64 ± 72.94) μmol/L on day 14 after ECD transplant (t =-2.686,P =0.011).Conclusion There was a higher recipient and graft survival rate after DCD and ECD kidney transplant,which would be an effective method to expand donor pool for kidney transplant.HMP was not associated with lower DGF rate in DCD kidney transplant and more rapid recovery in early graft function.However,HMP preservation not only made renal function recover more rapidly but reduced the risk of DGF after ECD kidney transplant.
RESUMO
Objective To investigate the effects of IL-10/TGF-β-modified macrophages on renal ischemia reperfusion injury (IRI).Methods Bone marrow-derived macrophages were modified ex vivo by IL-10/TGF-β to acquire M2c (a subset of activated macrophages).M2c were transferred into treated C57BL/6 mice by a single tail-vein injection at 6 h after renal IRI.Mice were killed on the day 3 after renal IRI.Blood samples were collected to check renal function.Kidneys were harvested to determine tubular necrosis and apoptosis by H&E staining and TUNEL assay.Immunofluorescence was performed to analyze the proliferating tubular cell nuclear antigen.Meanwhile,proinflammatory cytokines and regulatory T cells in renal tissues were analyzed with real-time PCR and flow cytometry.Results In comparison with M1,M2c expressed lower levels of MHC Ⅱ (P＜0.01),CD86 (P＜ 0.01),TNFα (P＜0.01) and IL-1β (P＜0.01) and higher level of IL-10 (P＜0.01).M2c significantly attenuated renal functional decline (P＜0.01 or 0.05),structural injury (P＜0.05),apoptosis of tubular cells (P＜0.01) and inflammation factors infiltration (P＜0.01 or 0.05).What's more,the cells could promote tubular cells proliferation (P＜0.05) and regulatory T cells expression (P＜0.01).Conclusion Our results demonstrated that M2c macrophages effectively protect against renal IRI and may become a therapeutic strategy for renal IRI.

RESUMO
<p><b>BACKGROUND</b>People's attitude toward organ donation after cardiac death (DCD) has not come to an agreement in different countries and regions. Influenced by the local culture in China for thousands of years, the general public has different ideas about this issue. The purpose of this study was to investigate the current attitudes trend and characteristics of transplantation with organs donated after cardiac death in northwest China.</p><p><b>METHODS</b>This largest single-center cohort study was performed by an interview or by telephone using a questionnaire. The family members of potential DCD donors were recruited from the First Affiliated Hospital, medical college of Xi'an Jiaotong University located in a metropolitan area of northwest China. The 12-item attitude questionnaire was specifically developed from the literature review with coordinator, physician, and donor's family feedback. The participants were asked to rate the queries on a 5-point Likert intensity scale.</p><p><b>RESULTS</b>The 174 participants included 56 (32.2%) women and 118 (67.8%) men. Most people were aged between 41 and 50 years (n = 63, 36.2%), 31 and 40 years (n = 59, 33.9%), and less than 30 years (n = 36, 20.7%). The top five attitudes of participants were the best person to suggest organ donation to a family was ranked as the DCD coordinator of Red Cross Organization (RCO, n = 160, 92%), donor is a hero (n = 143, 82.2%), honor to be a donor's family member (n = 136, 78.2%), improved relationship with colleagues (n = 124, 71.3%), and with recipient after donation (n = 123, 70.7%). The best person to suggest organ donation to a family was ranked as the coordinator of RCO (n = 160, 92%), doctor unrelated to transplantation (n = 104, 59.8%), social worker (n = 36, 20.7%), and doctor related to transplantation (n = 25, 14.4%). The top two reasons for non-consent to donation were that the family insisted on intact body after patient death and did not want to have surgery again (n = 51, 41.5%), and feared that they would be misunderstood by neighbors, relatives, and friends about donation (n = 28, 22.8%).</p><p><b>CONCLUSIONS</b>This study revealed initial attitudes toward DCD in China. Some data afford insight into the decision-making procedure. The concerns of potential DCD donors and their families may help professionals provide better interventions in the future.</p>
