Background There is still controversy about which preservation solution in pancreas transplantation could be the best. The aim of this study was to analyze our initial experience with Custodiol solution (CuS) compared with Viaspan solution (VS) and Celsior solution (CS) in pancreas transplantation. Methods A retrospective study included 94 consecutive pancreatic transplants, from 2007 until 2015. We compared 3 groups, depending on preservation solution: Viaspan (n = 41), Celsior (n = 40), or Custodiol (n = 13). The primary end point was patient and pancreas survival at 1 year after pancreas transplantation. Results The recipient and donor characteristics were similar except in cold ischemia time; it was higher with Celsior. No differences were found in postoperative complications and pancreas graft function at 3 months, 6 months, and 1 year (glucose, HbA1c, C-peptide, creatinine). The pancreas and patient survival at 1 year was comparable (pancreas survival: VS, 80%; CS, 90%; CuS, 92%; log-rank, 0.875; and patient survival: VS, 92%; CS, 97%; CuS, 100%; log-rank, 0.9). Conclusions In our institution, the Custodiol solution in pancreas transplantation presented similar outcomes in terms of postoperative complications, pancreas graft function, and 1-year survival.

Background C3 glomerulonephritis (C3GN) is an unusual entity that is caused by dysregulation and hyperactivity of the alternative complement pathway. Renal biopsy immunofluorescence study shows C3 deposits with absence of immunoglobulins and markers of the classical complement pathway. More than 50% of cases develop end-stage renal disease. Less well-known is the course of C3GN after kidney transplantation. Case Report We present the case of a 60-year-old woman with chronic kidney disease secondary to chronic glomerulonephritis of unknown origin who received a kidney transplant. Two years later, she presented worsening renal function with non-nephrotic proteinuria and microhematuria. Complement testing revealed low serum levels of C3. Kidney biopsy showed alterations compatible with C3GN that we interpreted as a relapse of the underlying disease.

Background Induction therapy for simultaneous pancreas-kidney (SPK) transplantation. Both thymoglobulin (ATG) and basiliximab are the most-used types of induction antibodies therapies in clinical practice. The aim of our report was to analyze our experience comparing 2 induction therapies, for SPK transplantation in terms of pancreas and patient survival, as well as rejection rate. Methods We reviewed retrospectively a total of 97 SPK transplantations in our institution. The cases were divided according to induction therapy in 2 groups, basiliximab (n = 38) and ATG (n = 59). Rejection, patient and graft survival, and postoperative complications were analyzed. Results Survival in the ATG group was better without statistical difference at 1-, 3-, and 5-year follow-up (97%, 95%, and 95% versus 92%, 90%, and 87%, respectively). No difference was detected in pancreas graft survival after 1-, 3-, and 5-year follow-up (basiliximab 85%, 80%, and 77% versus ATG 84%, 84%, and 81%, respectively; log-rank, 0.847). Overall cellular rejection and early rejection were more common in the basiliximab group (30 versus 14%, and 21% versus 6%). In the multivariate analysis considering human leukocyte antigen (HLA) mismatches, the ATG group was a protective factor for cellular rejection. Major complications (Grade III-IV) and median length of the hospital stay were higher in the basiliximab group (55% versus 34%, P = .057, and 21 versus 16 days, P = .056). Conclusions The pancreas graft survival was not affected by induction therapy. ATG induction therapy compared with basiliximab is associated with lower overall and early rejection rate. Over time this difference disappears.

Background Pancreas transplantation offers excellent outcomes today in patients who have type-1 diabetes mellitus (DM) with difficult control in terms of increasing patient and pancreatic graft survival. Different factors in donors, recipients, and the perioperative period have been associated with long-term graft survival. The aim of this study was to compare pancreatic graft survival in simultaneous pancreas-kidney transplantation (SPK) and the other two modalities, pancreas-alone and pancreas-after-kidney transplantation (non-SPK), at our institution. Methods This retrospective cohort study included 63 pancreas transplantation patients from January 2007 to May 2012 at our institution. The patients were divided into two groups: SPK and non-SPK transplantations. We excluded those patients who had transplants with vascular graft loss. The primary endpoint was 1-year and overall graft survival with consideration of multiple relevant variables. Non-parametric tests were calculated with the statistical package SPSS 20 (SPSS INC, Chicago, IL). Results The 1-year and overall graft survival in this period was 87.3% and 82.5%, respectively. The median follow-up was 963 days. The causes of graft loss were vascular (64%) and immunologic (34%). Finally, we included 56 pancreas transplantations, 46 (82%) were SPK and 10 (18%) non-SPK. The donor and recipient characteristics were similar in both groups, except for the duration of DM (SPK 22 years vs. non-SPK 29 years) and recipient body mass index (SPK 23 vs. non-SPK 28); P = .042 and P = .003, respectively. The cold ischemia time was 563 minutes (standard deviation, 145). Bivariate analysis showed that long-term graft loss was only influenced by matching for gender ( P = .023). Using the Kaplan-Meier method, the pancreas graft survival was better in SPK than in non-SPK transplants (log rank .038). Conclusions Patients who receive pancreas-alone or pancreas-after-kidney grafts have shorter long-term graft survival. Multiple strategies should be applied to improve immunologic surveillance and obtain an early diagnosis of graft rejection.

Background Vascular graft thrombosis (VGT) is still the achuilles heel in pancreas transplantation (PT); it is the main cause of nonimmunologic graft loss. Early diagnosis is essential to avoid transplantectomy. The aim of our study was to analyze the peak amylase during the first 3 days after PT as risk factor for VGT. Methods This retrospective study included 58 pancreas transplants in 55 patients from January 2007 to November 2011. They underwent an anticoagulation protocol based on unfractionated heparin and low-molecular-weight heparin. The technique consisted of enteric drainage and systemic venous drainage. The primary endpoint was VGT with consideration of multiple relevant variables. The maximum amylase level was determined during the first 3 days after transplantation. A receiver operating characteristic analysis was performed to establish a cutoff point as (mean plus one standard deviation; 745 mg/dL), calculating the sensitivity, specificity, and predictive values. Results Recipient characteristics were 71% males with an overall mean age of 39 years (range, 23–55) and body mass index 24 (range, 19–36). The donor sex was similar. Mean donor age was 32 years with occurrences of hypotension in 9%, cerebrovascular brain death in 46%. Mean ischemia time was 10 hours and 45 minutes. Mean blood amylase peak was 395 mg/dL. Seven VGT cases were diagnosed during the postoperative period including six with complete thrombosis requring transplantectomy. Bivariate analysis showed the group of subjects with amylase levels above 745 mg/dL to display on eight-fold greater risk for VGT (odds ratio = 8.6; P = .032). The area under the curve of blood amylase peak during the first 3 days to detect VGT was 0.630 (95% confidence interval 0.41–0.84). Conclusions A blood amylase peak above 745 mg/dL in the first 3 days after transplantation was associated with risk for VGT.
