ABSTRACT

Objective:To explore the outcome of kidney transplantation from donation after cadaveric death(DCD)with high pathological Remuzzi score.Methods:From January, 2019 to December, 2019, 31 recipients of kidney allograft transplantation from marginal donors with Remuzzi score≥4 in preimplantation biopsy were retrospectively enrolled. They were divided into two groups of dual kidney transplantation(DKT, 14 cases)and single kidney transplantation(SKT, 17 cases). Median Remuzzi score of left kidney(5.05 in DKT group vs 4.92 in SKT group)or right kidney(5.26 vs. 4.58)was comparable. Dual donor kidneys were implanted into ipsilateral iliac fossa. Survival outcomes, kidney function, acute rejection episodes, incidence of delayed graft function(DGF)and proteinuria were recorded within Year 1 post-operation.Results:Proportion of male(92.9% vs. 52.9%, P<0.05)and recipient's body mass index(BMI, 23.93 vs. 21.09)were significant higher in DKT group than those in SKT group. One graft failure occurred in DKT group at Month 11 post-operation. The 1-year graft survival rate was 92.9% in DKT group and 1-year recipient survival rate both 100% in two groups. Mean 12-month serum creatinine[SCr, (164±37.7)μmol/L vs. (154.92±96.2)μmol/L]and estimated glomerular filtration rate[eGFR, (41.84±9.01) vs. (44.8±18.16)ml/(min·1.73m 2)]were comparable between two groups(both P>0.05). There was no occurrence of thrombosis resulting in graft loss. One-year incidence of acute rejection, rate of DGF(42.9% vs 41.2%)and proteinuria(57.1% vs. 41.2%)were comparable between two groups(both P>0.05). Conclusions:Through donor-recipient matching and dual kidney transplant allocation, short-term survival outcome of kidney allograft from marginal donors with high Remuzzi score≥4 is encouraging. However, long-term outcomes should be further examined.

ABSTRACT

Objective:To summarize the clinical outcomes of en-bloc kidney transplantation from small infant donors to adult recipients at a single center.Methods:A total of 22 en-bloc transplantations from pediatric donors to adult recipients were performed from July 2013 to October 2017 in Institute of Organ Transplantation Affiliated Tongji Hospital Tongji Medical College Huazhong University of Science. Clinical data were retrospectively analyzed. The average age of 22 donors was (2.9±1.7) months with an average weight of (4.9±1.4) kg and 15 of them were aged under 3 months. The average weight of 22 adult recipients was (46.3±5.6) kg and most recipients were female. The causes of early graft failure and recipient death were examined during follow-ups. The recipients with functioning grafts post-transplantation were divided into single kidney survival group and en-bloc kidney survival group based upon the occurrence of unilateral vascular thrombosis. Medium/long-term renal graft function was compared between two groups.Results:Early graft failure occurred in 4 recipients. The causes were bilateral renal vascular thrombosis ( n=2), renal rupture ( n=1) and multiple organ failure followed by death ( n=1). Eighteen recipients were discharged after a recovery of renal graft function. One case had a removal of bilateral renal grafts due to new-onset graft tumor and another two died from interstitial pneumonia and complicate systematic disorder respectively during follow-ups. Among the remaining 15 recipients, 10 achieved bilateral renal survival (median follow-up: 59 months) and 5 unilateral renal survival (median follow-up: 48 months). The average eGFR of bilateral renal survival group was significantly higher than that of unilateral renal survival group at Year 1 post-transplantation (95±27 vs 61±24 ml/min/1.73 m 2, P<0.05) while the gap narrowed at Year 3 and there was no statistical significance (95±21 vs 69±31 ml/min/1.73 m 2, P=0.12). Conclusions:Although en-bloc kidney transplantation from infant donors can expand organ donor pool, there is a higher risk of early graft failure and unilateral renal vascular thrombosis. Nevertheless, satisfactory renal transplant outcomes may be achieved in patients with unilateral renal graft survival.

ABSTRACT

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

ABSTRACT

Objective:To summarize the transplant outcomes of pediatric kidney transplantation at a single center and discuss probable measures of improving the outcomes.Methods:A total of 111 pediatric renal transplantation were performed from September 2002 to September 2019. They were divided into adult-donor group ( n=41) and pediatric-donor group ( n=70). Adult-donor group consisted of two subgroups based upon donor sources: living-donor group ( n=19) and deceased-donor group ( n=22). Pediatric-donor group consisted of two subgroups based upon surgical types: single kidney group ( n=48) and en bloc kidney group ( n=22). Clinical data and outcomes of grafts and recipients were retrospectively analyzed. Results:The average age of recipients was (15.6±1.9) years in adult-donor group. None developed delayed graft function (DGF) in living-donor group whereas 6 patients (27.3%) had DGF in deceased-donor group ( P<0.05). During a follow-up period of 22-181 months, 1-year and 5-year graft survivals were 100% vs 94.1% and 93.8% vs 94.1% in living-donor and deceased-donor groups respectively. There were no statistical differences. In pediatric-donor group, the age of donors was significantly lower in en bloc subgroup than that in single kidney subgroup (median: 0.5 vs 6 months, P<0.05). The age of recipients was similar between two subgroups: (9.5±5.3) years in single kidney group vs. 11.5± 1.8 years in en bloc kidney group. In addition, 7 cases of single kidney were transplanted for infant recipients aged under 1 year. Vascular thrombosis occurred in 3 patients (6.3%) of single kidney group, less than that in 5 patients (22.7%) of en bloc kidney group ( P=0.06). During a follow-up period of 4-54 months, 1-year and 2-year graft survivals were 85% and 80% in single kidney group whereas 75% and 70% in en bloc kidney group. However, there was no statistically significant difference. One-year survival was 98% in single kidney group and 95% in en bloc kidney group. Conclusions:For elder pediatric recipients, excellent kidney transplant outcomes may be achieved with grafts from adult donors. For pediatric kidney recipients, transplant outcomes can be further improved with careful assessments and cautious usage of small grafts, particularly those form neonatal donors.

ABSTRACT

Objective To investigate the feasibility and safety of the single kidney transplantation from pediatric donors to adult recipients.Methods From May 2013 to January 2017,a total of 50 single kidney transplants from pediatric donation after citizen death (DCD) donors of age between 3 to 12 years to adult recipients were performed and the data were summarized.Results The average age of donors was 6.4 ± 2.5 years with an average donor weight of 19.1 ± 5.9 kg,and the average kidney length was 6.3 ± 0.6 cm.For the 50 adult recipients,the average age was 38.5 ± 12.1 years,the average body weight was 56.1 ± 13.1 kg,and the number of female patients was 26 (52%).All except 3 of these patients were transplanted for the first time.Delayed graft function (DGF) was observed in 15 patients (30%).The average value of eGFR among all the patients was rapidly increased in the first 3 months after transplantation and then steadily increased to (82.3 ± 13.4) mL· min-1·1.73 m-2 at 1 st year,followed by (83.8 ± 22.5) mL· min-1·1.73 m-2 at 2nd year.Four renal grafts developed acute rejection (8%),and 3 of them were successfully reversed by the treatment.Pulmonary infection occurred in 4 recipients,and 2 died.During a follow-up period of 19 months,uncensored grafts survival was 94%,and patients survival was 96%.Conclusion Excellent intermediate-term transplant outcome can be achieved by using single kidneys from pediatric donors elder than 3 years,which may shorten the waiting time in adult recipients and alleviate the contradictions in the absence of suitable pediatric recipients.

ABSTRACT

Objective To analyze the safety of renal transplant from donors with primary central nervous system (CNS) tumors.Methods We retrospectively analyzed the clinical data of 33 donors with primary CNS tumors and the 63 corresponding renal recipients between January 2013 and December 2016 in Tongji Hospital.Results The mean period from diagnosis as primary CNS tumor to donation was about (21.8± 46.4) months (range:0.5 to 192.0 months).The pathological classification of these tumors included gliomas,meningioma,medulloblastoma,etc.Besides,there were 10 donors with high-grade CNS malignancies.Eleven donors have ever been through at least one of the four treatments (craniotomy,V-P/V-A shunt,radiotherapy and chemotherapy),14 donors have undergone none,and the clinical data of rest were unavailable.All the 63 recipients got well renal function after transplant.During an average follow-up of (15.9 ± 8.2) months (range:2.7 to 35.5 months),one recipient got donor-derived rhabdoid tumor 4 months posttransplant,underwent comprehensive treatments,including allograft nephrectomy,radiotherapy,chemotherpy and returned to hemodialysis,while the 62 cases got no donor-derived tumors.Conclusion Tumor transmission of renal allograft from donors with primary CNS tumors is inevitable but with low risk,which means this kind of donors can be used with careful assessment,full informed consent and good balance between wait-list death and tumor transmission.

ABSTRACT

Objective To summarize the effect of en bloc kidney transplantation (EBKT) from cardiac deceased infant donors into adult recipients and to share a new simplified EBKT technique.Methods Fourteen dual kidneys from infant donors (9 males,and 5 females) were transplanted into adult recipients (3 males,and 11 females).The donor ages ranged from 17 days to 8 months,and the recipient ages ranged from 19 years to 61 years.The recipients were categorized into 2 groups in terms of the microvascular surgical techniques.Case 1 to case 9 was given traditional techniques and case 10 to case 14 simplified techniques.In detail,the dual kidneys were recovered en bloc with the aorta and inferior vena cava.After splitting the rear wall of the donor aorta and inferior vena cava,suitable size of patches were made by cutting along the vascular openings of renal arteries and renal veins.We anastomosed the aorta patch to the external iliac artery in an end-to-side fashion.The donor inferior vena cava patch was anastomosed to the external iliac vein in an end-to-side fashion.The distal ends of ureters were implanted into the bladder separately.Results In traditional group,two cases underwent peri-operative graft loss because of renal artery thrombosis,and one patient died of pneumonia 16 days post-operation.During the follow-up period,graft loss was seen in 2 patients caused by irreversible drug-induced nephrotoxicity and donor-derived malignant tumor respectively.The mean serum creatinine level was 81.7 ± 27.4 μmol/L and eGFR level was 82.5 ± 22.2 mL/min/1.73 m2 in the other EBKT recipients at 24th week post-operation.In simplified group,no vascular complications post-operation occurred.Conclusion En bloc infant kidneys could be transplanted into adult recipients successfully with excellent graft function and survival outcome while censored perioperative patient death and surgical failure.Instead of traditional EBKT technique,simplified EBKT technique could decrease the incidence of surgical vascular complications and should be applied to more recipients.

ABSTRACT

Objective To evaluate the role of native ureter for the management of renal transplantation urological complications retrospectively.Method Twenty-six renal transplant recipients (18 males and 8 females) experienced the following urological complications:upper ureter injury,urinary leaks and moderate or severe ureteric obstructions secondary to ureterovesical anastomotic stricture.These complications have been managed with minimally invasive endourologic techniques or percutaneous nephrostomy as the first-line intervention.While endourologic treatment did not succeed,and the recipients have been treated with intraperitoneal open surgical correction.Urinary continuity was established by pyeloureterostomy or ureteroureterostomy using recipient native ureter.A pigtail ureteral stent was placed with the tip positioned in the pelvis of the graft and native bladder and removed after 4 to 6 weeks.Result The recipients were managed successfully during a follow-up period of 6 months to 6 years without occurrence of urological complications.One case underwent graft loss due to chronic rejection 5 years later postoperation,and the rest developed stable renal function with baseline serum creatinine.Conclusion Excellent outcomes have been achieved by the use of recipient native ureter for the management of urological transplant complications.This simple and efficient procedure should be considered as the superior choice for the recipients who experienced urological complications while less invasive endourologic techniques failed.

ABSTRACT

Objective To determine the long-term results after combined pancreas-kidney transplantation at a single-center institution.Methods Fifty-three consecutive patients with insulin-dependent diabetes mellitus and end-stage nephropathy were followed up for more than three years after combined pancreas-kidney transplantation. Immunosuppressive protocol consisted of tacrolimus ( TAC ),mycophenolate mofetil (MMF),and steroids,and antithymocyte globulin or anti-CD25 receptor mAb.The impact of different risk factors was analyzed on long term patient and graft survival.Results The 3-,5- and 8-year survival rate in recipients was 90.1%,89.1 % and 80.0%,respectively.The 3-,5- and 8-year survival rate of pancreas grafts was 84.9%,84.8% and 60.0%,and that of kidney grafts was 83.0%,82.6% and 53.3%,respectively.Principal causes of death were Infection (n =4),renal failure (n =2),cardiovascular events (n =1 ),and cerebrovascular accident (n =1 ).Graft failure for the pancreas was caused by death with a functioning graft (n =6),rejection (n =2),thrombosis (n =1 ) and pancreatitis (n =1 ).Graft failure for the kidney was due to rejection (n =9),and death with a functioning graft (n =9).Conclusion This series representing the largest experience with long-term follow up in China confirms an excellent long-term survival.Infection,rejection and surgical complication were the major risk factors leading to deaths and graft loss.

Objective To evaluate the common causes of chronic cough and the diagnostic value of clinical symptoms,and provide evidences for empirical treatment.Methods The causes of patients with chronic cough were evaluated by a validated systematic diagnostic protocol.The characteristics of the cough timing,characters,incentives and associated manifestations of chronic cough with different causes were compared.Results A total of 160 patients with at least 8 weeks of chronic cough and normal chest radiographswere recruited from the Department of respiratory diseases of Yichang Central Hospital between Jan.to Dec.2009.The most common causes of chronic cough were cough variant asthma (CVA,n =72,45% ),upper airway cough syndrome ( UACS,n =54,33.75% ),eosinophilic bronchitis ( EB,n =14,8.75% ),gastroesophageal reflux-related chronic cough ( GERC,n =9,5.63% ),other etiologies ( n =11,6.87% ).Significant differences were observed in different etiological subtypes.The incidence of nocturnal cough in CVA was 52.8% ( 38/72 ),significantly higher than others types ; URCS patients manifested more day coughs,with 70.2% postnasal drip syndrome and significantly more cases had the history of nasal diseases compared with other types.The specificity of cough associated with meals in GERC were 66.7%,and the regurgitation associated symptom in GERC were77.8%,significantly higher than other types.However no special syndromes were observed in EB patients.Conclusion All kinds of chronic coughs have specific symptoms.The spectrum of causes and clinical features of chronic cough are important in the diagnostic procedure of chronic cough.
