ABSTRACT
Objective To explore the efficacy and safety of two antibody induction therapies during donor after cardiac death (DCD) kidney transplantation .Methods Retrospective analysis was performed for the clinical data of DCD kidney patients in 2016 .Patients using basiliximab monoclonal or thymoglobulin (ATG ) polyclonal antibody were divided into two groups . Early postoperative biopsy proven ,acute rejection rate ,creatinine level and patient/graft survival rate were compared between two groups at 1 ,3 or 6 month post-operation .Results Basiliximab (n=44) and ATG (n=60) was used as induction .No significant inter-group difference existed in donor age ,primary disease , creatinine pre-donation , recipient age or cause of renal failure . And recipient male ratio and body weight were greater in ATG group than those in basiliximab group [87％ vs .55％ ;(70 ± 13) vs .(64 ± 12) kg] .Outcomes of basiliximab group showed acute rejection rate was 9％ ,average creatinine 112 .4 at 1 month ,127 .0 at 3 months and 107 .8 at 6 months and total infection rate 16％ .Graft/patient 6-month survival rates were 95％ (42/44)and 98％ (43/44) .Outcomes of ATG group showed that acute rejection rate was 3％ ,average creatinine 135 .6 at 1 month ,119 .0 at 3 months and 118 .0 at 6 months and total infection rate 22％ .Graft/patient 6-month survival rates were both 100％ (60/60) .Conclusions During DCD kidney transplantation ,both induction therapies may prevent acute rejection immediately post-operation .No difference exists in acute rejection rate ,infection rate ,graft/recipient 6-month survival rate or graft function . These two inductions have an excellent early prognosis .
ABSTRACT
Objective To investigate the clinical effect of donor kidneys in rhabdomyolysis(RM) combined with acute kidney injury(AKI).Methods A retrospective analysis was made on the clinical data of 10 donors with RM and 14 cases of renal transplantation from March 2017 to May 2018.Results AKI was caused by RM in 10 donors.Before harvesting the donor kidneys,blood creatine kinase (CK) level was (14 005.19 ± 11 894.27) U/L in 10 donors,plasma myoglobin level was ＞3 000 μg/L in 7 cases,and that was (2 288 ± 680) μg/L in 3 cases.LDH level was 883 ± 453 IU/L and serum creatinine (Cr) value was (216.55 ± 125) μmol/L.6 donors received continuous renal replacement therapy.Six patients with delayed renal function recovery (DGF) were treated with CRRT.The duration of GDF was 3-20 days,with an average of 10 ± 6.6 days.All the patients were followed up for 3-15 months.The glomerular filtration rate was (40.19 ± 19.55) ml·min· 1.73 m-2 and (55.01 ± 15.94) ml · min· 1.73 m-2 at 1st and 3rd month after operation,respectively.Conclusion The incidence of DGF in donor kidneys with RM and AKI is high,and the short-term effect is satisfactory.The long-term effect needs to be further observed.
ABSTRACT
Objective To compare the impact of the sirolimus and tacrolimus on the tumor recurrence after liver transplantation due to HCC beyond Milan criteria.Method Sixty-one liver transplantation recipients due to HCC beyond Milan criteria,between Jan.2008 and Apri.2012,were randomized,with the informed consent,into two different immunosuppression groups: sirolimus group (n=30) and tacrolimus group (n=31).In tacrolimus group,tacrolimus was used as the basic immunosuppressant,methylprednisolone was discontinued within one month postoperatively,and mycophenolate mofetil was used within the dosage of 1.5 g/d accordingly.In sirolimus group,the immunosuppresive scheme was the same as that of the tacrolimus group within postoperative one month,and from that,tacrolimus was transferred to sirolimus.No antineoplastic agents were given before tumor recurrence.The tumor recurrence rate and the survival rate of the recipients were compared between the two groups.Result The median follow-up duration was 35.2 months (10.3～ 60.2).The tumor recurrence rate at postoperative year 1,2,3 and 4 in the sirolimus group (13.3％,36.7％,43.3％ and 53.3％) was significantly lower than that in the tacrolimus group (38.7％,67.7％,74.2％ and 77.4％),P ＜ 0.05 for all.The one-year survival rate in the recipients postoperation had no significant difference between sirolimus group and tacrolimus group (90.0％ vs.87.1％,P=0.438).The 2-,3-and 4-year survival rate in the recipients was significantly higher in the sirolimus group (53.3％,33.3％ and 20.0％) than that in the tacrolimus group (41.9％,22.6％ and 9.7％),P ＜ 0.05 for all.The liver function and renal function of the recipients at the postoperative year 1,2,3 and 4 showed no significant difference between the two groups,P＞0.05.Conclusion In comparison with tacrolimus,sirolimus could significantly reduce the tumor recurrence rate and increase the survival rate for the liver transplant recipients due to HCC beyond Milan criteria.
ABSTRACT
Objective To explore the treatment of ABO-incompatible orthotopic liver transplantation. Methods Nine cases of ABO-incompatible liver transplantation performed in our hospital were analyzed retrospectively. Plasma exchange was done before the operation in 1 case. Hepatic artery and biliary duct anastomosis were performed by the microvascular technique. Splenectomy was done during operation in 5 cases. The immunosuppressive protocol included a quadruple drug therapy. Blood oxygen saturation was maintained above 95% and anticoagulant therapy was performed after operation.Results Four patients recovered smoothly without complications. Postoperative complications included acute rejection in 3 patients and biliary nonanastomotic stricture in 4. Three patients died. Conclusion ABO-incompatible orthotopic liver transplantation can be used when the graft is scarce, and should manage to decrease the complications.
ABSTRACT
Objective To probe into the value of micro-perfusion examination at the early stage after right lobe living donor liver transplantation by contrast-enhanced ultrasound(CEUS). Methods Twenty-six recipients of right lobe living donor liver transplantation received CEUS examination at 1,7,15 and 30 days respectively after operation using contrast medium SonoVue. Perfusion patterns were observed and analyzed considering operation method. Results Of 26 recipients, 15 cases showed normal perfusion patterns with normal hemodynamics; 11 cases showed abnormal perfusion patterns with abnormal hemodynamics:8 had conduit venous obstruction,4 high portal vein blood flow. The abnormal patterns was in the early arterial phase of enhancement process at the first day examination, showing hyper- and hypo- enhancement area compared with normal liver parenchyma. And the difference gradually disappeared in the subsequent examination. Conclusions Abnormal micro-perfusion patterns are highly related to abnormal inflow and outflow in the early post operation stage. The main reasons are conduit venous obstruction and excessive perfusion of portal vein. CEUS can be used as an effective method in evaluating the graft micro-perfusion.
ABSTRACT
25 ?g/L) before transplantation were followed-up following liver transplantation. Patients were divided into three groups according to the postoperative time of serum AFP below 25 ?g/L, group A (within 1 month ),group B (within 2 months ) and group C(no decreasing or rising after decreasing). Results:The average half-life time of serum AFP of recurrence group was obvious longer than that of the non-recurrence group (P
