ABSTRACT

Objective:To explore the risk factors of paralytic ileus (PI) after simultaneous pancreas-kidney (SPK) transplantation.Methods:From January 2017 to December 2019, clinical data were reviewed retrospectively for 115 cases of SPK transplantation. The risk factors of PI after SPK were analyzed. According to the occurrence of PI, they were divided into two groups of occurrence and non-occurrence. One-way analysis of variance was utilized for analyzing such influencing factors as gender, age, body mass index (BMI), diabetic type, duration of diabetes, mode of dialysis, duration of dialysis, diabetic gastroenterology, history of open surgery, bowel preparation, operative duration, hemorrhagic volume, immunosuppressant and hypoproteinemia. Multivariate Logistic regression analysis was performed for screening the suspected risk factors.Results:Among them, 19 patients (16.5%) had PI. Univariate analysis showed that PI was associated with diabetic gastroenterology, operative duration, history of open surgery, no bowel preparation and hypoproteinemia ( P<0.05). Multivariate Logistic regression analysis revealed that the risk factors of PI after SPK included diabetic gastroenterology, operative duration time, history of open surgery and no bowel preparation ( P<0.05). Conclusions:Diabetic gastroenterology, operative duration, history of open surgery and no bowel preparation are risk factors for PI after SPK. Clinical interventions for the above factors are necessary.

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

To summarize the clinical experience regarding a patient with early recurrence of atypical hemolytic uremic syndrome (aHUS) after renal transplantation. AHUS is a rare disease with high recurrence rate and poor prognosis. Although the patient was treated with plasma exchange, intravenous gamma globulin, rituximab block B lymphocyte, hormone shock and so on, he still suffered renal transplantation failure. The risk of aHUS recurrence after renal transplantation should be fully evaluated.

ABSTRACT

Objective@#To investigate the effect factors of liver enzymes elevation by monitoring the liver function changes before and after intraportal islet transplantation.@*Methods@#16 diabetic patients who received intraportal islet transplantation in our hospital were analyzed. The levels of aspartic aminotransferase (AST), alanine aminotransferase (ALT)and total bilirubin (TBil)were monitored after islet transplantation.@*Results@#Among those 16 diabetic patients who received intraportal islet transplantation, 11 patients showed an increased AST and 8 patients showed an increased ALT, among which a 2.5-fold increase in AST was observed in 4 patients and over 1.5-fold elevation of ALT was observed in 3 patients. The level of TBil were in the normal range before and after transplantation in all patients. Transplanted tissue volume of islet was the main factor for significantly increased AST (P<0.05) in this study. It is also shown that the change in portal pressure is related to the AST elevation after islet transplantation.@*Conclusions@#The amount of transplanted islet tissue volume is related to the liver enzymes elevation after intraportal islet transplantation. Therefore, the improvement of the purity of islet to reduce the amount of transplanted tissue could be benefit to prevent the liver injury after islet transplantation. Meanwhile, the purified islets should be injected as slowly as possible to maintain a stable portal pressure.

ABSTRACT

Objective To retrospectively compare the efficacy of Serva NB1 collagenase with Vitacyte GOLD collagenase on islet isolation of pancreas.Methods All the human pancreata were obtained from Chinese organ donors.In GMP laboratory,the pancreata were trimmed and distended with Serva NB1 collagenase (Serva NB1,n =12) or Vitacyte GOLD collagenase (Vitacyte GOLD,n =5) and digested according to a modified Ricordi semi-automatic protocol,and the digestion duration was recorded.The digested islets were then collected and washed,followed by the continuous density purification in a Cobe 2991 cell separator.The islet yield,purity,viability and glucose-stimulated insulin release (GSI) were determined each time after purification.Quantity and quality of isolated islets were determined by digestion efficacy.Results The digestion duration in Vitacyte GOLD collagenase group was significantly shorter than in Serva NB1 collagenase group to achieve the same digestion endpoint (P< 0.05).The islets yields of different sizes were variable between the two groups.The Vitacyte GOLD collagenase digestion produced more islets with a diameter range of 50-100 μm than the ServaNB1 collagenase digestion (P<0.05),but the latter yielded more islets with a diameter range of 251-300 μm and 301-350μm (P<0.05).There was no significant difference in total islets yields,viability,and GSI between two collagenase digestions (P>0.05).Conclusion Both Vitacyte GOLD collagenase and Serva NB1 collagenase can be used for the clinical islet isolation in China.

ABSTRACT

The percutaneous transhepatic portal approach is the most commonly used technique for islet transplantation, largely owing to its safety and minimally invasive characteristic. Bleeding complications after islet transplantation are rare. A case of type 1 diabetes mellitus (T1DM) was treated in Tianjin First Center Hospital, who had a massive intra-abdominal hemorrhage after percutaneous transhepatic portal vein catheterization for islet transplantation. Through the review of the overall development of the case, we aim to improve the awareness of the complications of islet transplantation, to reduce the incidence of complications after percutaneous transhepatic portal vein transplantation, and to provide experience.

ABSTRACT

Objective To investigate the value of Cytochrome P450 (CYP3A5) * 3 gene polymorphism in providing individualized administration for the use of tacrolimus (Tac) in renal transplantation recipients.Method Pyrophosphate sequencing method was used to determine the CYP3A5 * 3 genotype of renal transplant patients in the first day after surgery.Sixty recipients were divided into experiment group and control group.Both groups of patients were routinely given the initial dose of Tac-4.0 mg/day in the first day after surgery.The experiment group of patients were given different doses of Tac based on the different CYP3A5 * 3 genotypes at the third day after surgery [for AA:0.12 mg/(kg· day),and for GG:0.06 mg/(kg· day)],and the control group of patients were given different dosages of Tac according to drug concentration.Different parameters were compared between two groups of patients:percentage of patients reaching the target concentration (3-8 μg/L) at the fifth day after surgery,days required to reach the target concentration level,times needed to adjust the dosage of Tac within two weeks.Result The percentage of patients reaching the target concentration in experiment group and control group was 90% and 46.67%,respectively (P< 0.05).Days required to reach the target concentration were (3.67 ± 1.32) and (7.57 ± 3.42) on average,respectively (P < 0.05).Times of adjusting the Tac dose in experiment group was significantly less than those in the control group (P<0.05).In the experiment group,the target concentration was obtained even without dosage adjustment (70%).Conclusion Individualized adjustment of Tac doses for patients according to recipients' different CYP3A5 * 3 genotypes is beneficial for reaching target concentration as soon as possible,which is superior to traditional dosage regimen.

ABSTRACT

Objective To improve the awareness,diagnosis and treatment of pneumocystis carinii pneumonia (PCP) after renal transplantation.Methods A retrospective review was performed in 28 patients who underwent renal transplantation and developed PCP afterwards.The main clinical manifestations were fever(28 cases),nonproductive cough(28 cases),chest distress (12 cases).Occurrences of PCP were described 1.5 to 7 months after the renal transplantation.There were 10 patients treated with tacrolimus (FK506 2-6 rag/d,FK506 concentration 4-10 ng/ml) and 18 patients treated with cyclosporine (CsA 200-500 mg/d,CsA trough level:150-250 ng/ml) based immunosuppressive regimen.Anti-CD_(25)~+ monoclonal antibody (anti-CDCD_(25)~+mAb) was used in 10 cases for immune induction before operation while single steroid in 18 cases.Creatinine of patients with PCP was 70 to 106 μmol/L.CD_4~+ lymphocyte counts of the peripheral blood were 245±32/μl before PCP treatment and 536±25/μl after recovery.The most abnormal chest radiological findings were bilateral patchy ground-glass opacity.All the patients were diagnosed with PCP by bronchoalveolar lavage.Treatment was performed by reducing immunosuppressive agents and giving SMZco.Nineteen patients who had a PaP2 less than 70 mm Hg were given intravenous small-dose steroid.Results All the patients recovered from PCP 2 to 3 weeks after treatment.One patient experienced recurrence half year later.Five patients with higher creatinine after treatment recovered to normal levels after stopping the treatment of SMZco.No significant differences were seen in PCP patients treated with CsA and FK506,P>0.05.The similar results were observed in use of anti-CDCD_(25)~+ mAb and single steroid,P>0.05.Significant differences were observed in PCP patient peripheral blood CD_4~+ lymphocyte counts before and after treatment (P=0.001).Conclusions Patients who have fever,cough and hypoxia,chest imaging showing bilateral lung interstitial inflammation,might be PCP patients in the early post-renal transplantation period.Effective treatment should be performed by reducing immunosuppressive agents and giving SMZco.
