ABSTRACT

PURPOSE OF REVIEW: To define recent changes and future directions in the practice of pancreas transplantation (PT). Two major events have occurred in the past 18 months: COVID-19 pandemic, and the first world consensus conference on PT. Several innovative studies were published after the consensus conference. RECENT FINDINGS: During COVID-19 pandemic PT activity decreased. COVID-19 in transplant recipients increases mortality rates, but data from kidney transplantation show that mortality might be higher in waitlisted patients.The world consensus conference provided 49 jury deliberations on the impact of PT on management of diabetic patients and 110 practice recommendations.Recent evidence demonstrates that PT alone is safe and effective, that results of simultaneous pancreas and kidney (SPK) remain excellent despite older recipient age and higher prevalence of type 2 diabetes, that use of hepatitis C virus (HCV)-positive donors into HCV-negative recipients is associated with good outcomes, and that use of sirolimus as primary immunosuppressant and costimulation blockade does not improve results of SPK. SUMMARY: COVID-19 pandemic and the first world consensus conference on PT were major events. Although COVID-19 pandemic should not reduce PT activity in the future, a major positive impact on both volume and outcomes of PT is awaited from the proceedings of the world consensus conference.

ABSTRACT

PURPOSE: The feasibility of pancreas transplantation (PT) in older recipients remains a matter of debate. We examined the influence of recipient age on PT outcomes and identified the prognostic factors for older recipients. METHODS: We compared the outcomes of PT in recipients aged < 50 years (younger group; n = 285) with those in recipients aged ≥ 50 years (older group; n = 94). Prognostic factors in the older group were analyzed by a logistic regression model and the influence of recipient age on survival outcomes were analyzed using propensity score matching. RESULTS: The patient survival rate was significantly worse in the older group (P < 0.001). Patient death from infection or/and multiple organ failure or cardiac/cerebrovascular events was also more frequent in the older group than in the younger group (P = 0.012 and P = 0.045, respectively). A longer duration of diabetes was an independent risk factor of 1-year mortality in the older group. In a propensity score-matched comparison, the older recipients (n = 77) had significantly poorer survival than the younger recipients (n = 77) (P = 0.026). CONCLUSIONS: PT should be considered with appropriate caution, especially for older recipients with a long duration of diabetes.

ABSTRACT

BACKGROUND: In many transplant centers, a recipient body mass index (BMI) >30 kg/m2 would be considered a contraindication for pancreas transplantation. This study aims to investigate the impact of recipient BMI on graft outcomes after pancreas transplantation. METHODS: Retrospective data on all UK solid organ pancreas transplants from 1994 to 2016 were obtained from the National Health Service Blood and Transplant UK Transplant Registry, n = 2618. Cases missing BMI data were excluded, resulting in a final cohort of n = 1452. Graft and patient survival analysis were conducted using Kaplan-Meier plots and Cox regression models. RESULTS: The mean recipient BMI was 24.8 kg/m2 (±2.4). There were 507 overweight (BMI 25-29.9) and 146 obese (>30) recipients receiving pancreas transplants. Univariate analysis showed no statistically significant difference between overweight BMI categories compared with normal BMI (18.5-24.9 kg/m2). Multivariate analysis revealed increasing recipient BMI had a significant impact on graft survival (P = 0.03, hazard ratio 1.04, 95% confidence interval, 1.00-1.08). Receiver operating characteristic curve analyses revealed no value of BMI that provided both specific and sensitive discrimination between death and survival of both grafts or patients. Recipients on dialysis with a BMI >30 kg/m2 had a statistically significant decrease in both graft (P = 0.002) and patient survival (P = 0.015). CONCLUSIONS: Analysis of available UK Pancreas data has shown recipient BMI is an independent risk factor for patient survival after transplantation. However, we have been unable to define a specific cutoff value above which patients have poorer outcomes. Obese patients on hemodialysis had the poorest graft survival, and preemptive transplantation may be beneficial in this cohort.

ABSTRACT

BACKGROUND: The risk of COVID-19 infection in transplant recipients (TRs) is unknown. Patients on dialysis may be exposed to greater risk of infection due to an inability to isolate. Consideration of these competing risks is important before restarting suspended transplant programs. This study compared outcomes in kidney and kidney/pancreas TRs with those on the waiting list, following admission with COVID-19 in a high-prevalence region. METHODS: Audit data from all 6 London transplant centers were amalgamated. Demographic and laboratory data were collected and outcomes included mortality, intensive care (ITU) admission, and ventilation. Adult patients who had undergone a kidney or kidney/pancreas transplant, and those active on the transplant waiting list at the start of the pandemic were included. RESULTS: One hundred twenty-one TRs and 52 waiting list patients (WL) were admitted to hospital with COVID-19. Thirty-six TR died (30%), while 14 WL patients died (27% P = 0.71). There was no difference in rates of admission to ITU or ventilation. Twenty-four percent of TR required renal replacement therapy, and 12% lost their grafts. Lymphocyte nadir and D-dimer peak showed no difference in those who did and did not die. No other comorbidities or demographic factors were associated with mortality, except for age (odds ratio of 4.3 [95% CI 1.8-10.2] for mortality if aged over 60 y) in TR. CONCLUSIONS: TRs and waiting list patients have similar mortality rates after hospital admission with COVID-19. Mortality was higher in older TRs. These data should inform decisions about transplantation in the COVID era.

ABSTRACT

BACKGROUND: Simultaneous pancreas-kidney transplantation (SPKT) profoundly improves the health-related quality of life (HRQoL) of recipients. However, the influence of the pre-transplant dialysis modality on the success of the SPKT and post-transplant HRQoL remains unknown. METHODS: We analyzed the surgical outcome, long-term survival, as well as HRQoL of 83 SPKTs that were performed in our hospital between 2000 and 2016. Prior to transplant, 64 patients received hemodialysis (HD) and nineteen patients received peritoneal dialysis (PD). Physical and mental quality of life results from eight basic scales and the physical and mental component summaries (PCS and MCS) were measured using the Short Form 36 (SF-36) survey. RESULTS: Peri- and postoperative complications, as well as patient and graft survival were similar between the two groups. Both groups showed an improvement of HRQoL in all SF-36 domains after transplantation. Compared with patients who received HD before transplantation, PD patients showed significantly better results in four of the eight SF-36 domains: physical functioning (mean difference HD - PD: - 12.4 ± 4.9, P = < 0.01), bodily pain (- 14.2 ± 6.3, P < 0.01), general health (- 6.3 ± 2.8, P = 0.04), vitality (- 6.8 ± 2.6, P = 0.04), and PCS (- 5.2 ± 1.5, P < 0.01) after SPKT. In the overall study population, graft loss was associated with significant worsening of the HRQoL in all physical components (each P < 0.01). CONCLUSIONS: The results of this analysis show that pre-transplant dialysis modality has no influence on the outcome and survival rate after SPKT. Regarding HRQoL, patients receiving PD prior to SPKT seem to have a slight advantage compared with patients with HD before transplantation.

ABSTRACT

BACKGROUND: In contrast to insulin-dependent type 1 diabetes mellitus (T1DM), the indication for Simultaneous pancreas-kidney transplantation (SPK) in patients with type 2 diabetes mellitus (T2DM) is still ambiguous and wisely Eurotransplant (ET) only granted transplant-permission in a selected group of patients. However, with regard to improvement of metabolic conditions SPK might still be a considerable treatment option for lean insulin dependent type 2 diabetics suffering from renal disease. METHODS: Medical data (2001-2013) from all consecutive T1DM and T2DM patients who received a SPK or kidney transplant alone (KTA) at the University Hospital of Leipzig were analyzed. Donor, recipients and long-term endocrine, metabolic and graft outcomes were investigated for T1DM and T2DM-SPK recipients (transplanted upon a special request allocation by ET) and T2DM patients who received a KTA during the same period. RESULTS: Eighty nine T1DM and 12 T2DM patients received a SPK and 26 T2DM patients received a KTA. Patient survival at 1 and 5 years was 89.9 and 88.8% for the T1DM group, 91.7 and 83.3% for the T2DM group, and 92.3 and 69.2% for the T2DM KTA group, respectively (p < 0.01). Actuarial pancreas graft survival for SPK recipients at 1 and 5 years was 83.1 and 78.7% for the T1DM group and 91.7 and 83.3% for the T2DM group, respectively (p = 0.71). Kidney allograft survival at 5 years was 79.8% for T1DM, 83.3% for T2DM, and 65.4% for T2DM KTA (p < 0.01). Delayed graft function (DGF) rate was significantly higher in type 2 diabetics received a KTA. Surgical, immunological and infectious complications showed similar results for T1DM and T2DM recipients after SPK transplant and KTA, respectively. With regard to the lipid profile, the mean high-density lipoprotein (HDL)- cholesterol levels were significantly higher in T1DM recipients compared to T2DM patients before transplantation (p = 0.02) and remained significantly during follow up period. CONCLUSION: Our data demonstrate that with regard to metabolic function a selected group of patients with T2DM benefit from SPK transplantation. Consensus guidelines and further studies for SPK transplant indications in T2DM patients are still warranted.

ABSTRACT

Cardiovascular events are among the most common causes of late death in the transplant recipient (Tx) population. Moreover, major cardiac surgical procedures are more challenging and risky due to immunosuppression and the potential impact on the transplanted organ's functional capacity. We aimed to assess open cardiac surgery safety in abdominal solid organ transplant recipients, comparing the postoperative outcomes with those of nontransplant (N-Tx) patients. Electronic databases of PubMed, EMBASE, and SCOPUS were searched. The endpoints were: overall rate of infectious complications (wound infection, septicemia, pneumonia), cardiovascular and renal events (stroke, cardiac tamponade, acute kidney failure), 30-days, 5-years, and 10-years mortality post-cardiac surgery interventions in patients with and without prior solid organ transplantation. This meta-analysis included five studies. Higher rates of wound infection (Tx vs. N-Tx: OR: 2.03, 95% CI: 1.54 to 2.67, I2 = 0%), septicemia (OR: 3.91, 95% CI: 1.40 to 10.92, I2 = 0%), cardiac tamponade (OR: 1.83, 95% CI: 1.28 to 2.62, I2 = 0%) and kidney failure (OR: 1.70, 95 %CI: 1.44 to 2.02, I2 = 89%) in transplant recipients were reported. No significant differences in pneumonia occurrence (OR: 0.95, 95% CI: 0.71 to 1.27, I2 = 0%) stroke (OR: 0.89, 95% CI: 0.54 to 1.48, I2 = 78%) and 30-day mortality (OR: 1.92, 95% CI: 0.97 to 3.80, I2 = 0%) were observed. Surprisingly, 5-years (OR: 3.74, 95% CI: 2.54 to 5.49, I2 = 0%) and 10-years mortality rates were significantly lower in the N-Tx group (OR: 3.32, 95% CI: 2.35 to 4.69, I2 = 0%). Our study reveals that open cardiac surgery in transplant recipients is associated with worse postoperative outcomes and higher long-term mortality rates.

ABSTRACT

OBJECTIVE: In patients with type 1 diabetes and end-stage renal disease, it is controversial whether a simultaneous pancreas-kidney (SPK) transplantation improves survival compared with kidney transplantation alone. We compared long-term survival in SPK and living- or deceased-donor kidney transplant recipients. RESEARCH DESIGN AND METHODS: We included all 2,796 patients with type 1 diabetes in the Netherlands who started renal replacement therapy between 1986 and 2016. We used multivariable Cox regression analyses adjusted for recipient age and sex, dialysis modality and vintage, transplantation era, and donor age to compare all-cause mortality between deceased- or living-donor kidney and SPK transplant recipients. Separately, we analyzed mortality between regions where SPK transplant was the preferred intervention (80% SPK) versus regions where a kidney transplant alone was favored (30% SPK). RESULTS: Of 996 transplanted patients, 42%, 16%, and 42% received a deceased- or living-donor kidney or SPK transplant, respectively. Mean (SD) age at transplantation was 50 (11), 48 (11), and 42 (8) years, respectively. Median (95% CI) survival time was 7.3 (6.2; 8.3), 10.5 (7.2; 13.7), and 16.5 (15.1; 17.9) years, respectively. SPK recipients with a functioning pancreas graft at 1 year (91%) had the highest survival (median 17.4 years). Compared with deceased-donor kidney transplant recipients, adjusted hazard ratios (95% CI) for 10- and 20-year all-cause mortality were 0.79 (0.49; 1.29) and 0.98 (0.69; 1.39) for living-donor kidney and 0.67 (0.46; 0.98) and 0.79 (0.60; 1.05) for SPK recipients, respectively. A treatment strategy favoring SPK over kidney transplantation alone showed 10- and 20-year mortality hazard ratios of 0.56 (0.40; 0.78) and 0.69 (0.52; 0.90), respectively. CONCLUSIONS: Compared with living- or deceased-donor kidney transplantation, SPK transplant was associated with improved patient survival, especially in recipients with a long-term functioning pancreatic graft, and resulted in an almost twofold lower 10-year mortality rate.

ABSTRACT

OBJECTIVES: The influence of peritoneal dialysis on outcomes after simultaneous pancreas and kidney transplant is still vague. In addition, whether peritoneal dialysis leads to a higher risk of infectious complications and higher mortality rates in these transplant patients has not been unambiguously confirmed. In this study, our aim was to verify whether dialysis type determined outcomes on the pancreas graft and whether dialysis type was a risk factor for graftectomy or recipient death. MATERIALS AND METHODS: Our study group included 44 simultaneous pancreas and kidney transplant patients. Analyzed parameters included type and duration of dialysis treatment, age, sex, long-term pancreas graft survival and patient survival, overall mortality, and number of graftectomies. RESULTS: Of 44 patients, 3 (7%) required a graftectomy. Mortality rate of the group was 5%. Of 44 patients, 33 had hemodialysis and 11 had peritoneal dialysis. In those who had hemodialysis, the mean duration of renal replacement therapy was 30.5 months, which was significantly longer than duration for those who had peritoneal dialysis (20.4 mo; P < .01). There were 3 graftectomies and 1 death in the hemodialysis group. In the peritoneal dialysis group, there were no graftectomies and 1 death, with no significant differences in the number of graftectomies and mortality rates between the groups. Long-term survival also did not differ between the groups. CONCLUSIONS: We found that type of dialysis did not affect outcomes in our group of simultaneous pancreas and kidney transplant patients. Before transplant, each patient requires an individual approach to treatment. The type of dialysis performed should not be viewed as a contradiction for transplant.

ABSTRACT

BACKGROUND: The effects of Simultaneous Pancreas Kidney Transplantation (SPKT) on Peripheral Vascular Disease (PVD) warrants additional study and more target focus, since little is known about the mid- and long-term effects on the progression of PVD after transplantation. METHODS: 101 SPKT and 26 Kidney Transplantation Alone (KTA) recipients with insulin-dependent diabetes mellitus (IDDM) were retrospectively evaluated with regard to graft and metabolic outcome. Special subgroup analysis was directed towards the development and progression of peripheral vascular complications (PVC) (amputation, ischemic ulceration, lower extremity angioplasty/ bypass surgery) after transplantation. RESULTS: The 10-year patient survival was significantly higher in the SPKT group (SPKT: 82% versus KTA 40%; P < 0.001). KTA recipients had a higher prevalence of atherosclerotic risk factors, including coronary artery disease (P < 0.001), higher serum triglyceride levels (P = 0.049), higher systolic (P = 0.03) and diastolic (P = 0.02) blood pressure levels. The incidence of PVD before transplantation was comparable between both groups (P = 0.114). Risk factor adjusted multivariate analysis revealed that patients with SPKT had a significant lower amount (32%) of PVCs (32 PVCs in 21 out of 101 SPKT; P < 0.001) when compared to the KTA patients who developed a significant increase in PVCs to 69% of cases (18 PVCs in 11 out of 26 KTA; P < 0.001). In line mean values of HbA1c (P < 0.01) and serum triglycerides (P < 0.01) were significantly lower in patients with SPKT > 8 years after transplantation. CONCLUSION: SPKT favorably slows down development and progression of PVD by maintaining a superior metabolic vascular risk profile in patients with IDDM1.

ABSTRACT

BACKGROUND: Total pancreatectomy for chronic pancreatitis leads to brittle diabetes and challenging glycemic control with half of all patients experiencing severe hypoglycemia, many requiring medical intervention or hospitalization. Pancreas transplantation has the potential to manage both the endocrine and the exocrine insufficiency in this patient population. METHODS: Between June 1, 2005, and July 1, 2016, 8 patients with brittle diabetes following total pancreatectomy underwent pancreas transplantation. All grafts had systemic venous and enteric exocrine drainage. Data included demographics, graft and patient survival, pre- and post-transplant supplementation with pancreatic enzymes, and narcotic usage. RESULTS: Patient survival rate at 1 and 3 years was 88%. Pancreas graft survival rate of those alive at 1 year was 100% and 86%, respectively. About 75% of these patients remained insulin-free until their time of death, loss of follow-up, or present day. Of the patients with maintained graft function at 3 years, none required further hospitalization for glycemic control. About 75% of these patients have also maintained exocrine function without pancreatic enzyme supplementation. CONCLUSIONS: Pancreas transplant can treat both exocrine and endocrine insufficiency and give long-term insulin-free survival and should be considered as a viable treatment option for patients who have undergone total pancreatectomy for chronic pancreatitis.

ABSTRACT

Simultaneous pancreas and kidney (SPK) and pancreas after kidney (PAK) transplant are both potential options for diabetic ESRD patients. Historically, PAK pancreas graft outcomes were felt to be inferior to SPK pancreas graft outcomes. Little is known about outcomes in the modern era of transplantation. We analyzed our SPK and PAK recipients transplanted between 01/2000 and 12/2016. There were a total of 635 pancreas and kidney transplant recipients during the study period, 611 SPK and 24 PAK. Twelve of the PAK patients received a living donor kidney. There were no significant differences between the two groups in kidney or pancreas graft rejection at 1 year. Similarly, 1-year graft survival for both organs was not different. At last follow-up, uncensored and death-censored graft survival was not statistically different for kidney or pancreas grafts. In addition, in Cox regression analysis SPK and PAK were associated with similar graft survival. Although the majority of pancreas transplants are in the form of SPK, PAK is an acceptable alternative. Simultaneous pancreas and kidney avoids donor risks associated with live donation, so may be preferable in regions with short wait times, but PAK with a living donor kidney may be the best alternative in regions with long SPK wait times.

ABSTRACT

BACKGROUND: Several studies in solid organ transplantation have shown a correlation between donor and recipient sex mismatch and risk of graft loss. In this study, we aimed to analyze the impact of donor and recipient sex matching on patient and pancreas graft survival in a large single-center cohort. METHODS: We retrospectively analyzed all first simultaneous pancreas-kidney transplants performed between 1979 and 2017 at the Medical University of Innsbruck. RESULTS: Of 452 patients, 54.6% (247) received a sex-matched transplant. Patient survival (P = .86), death-censored pancreas graft survival (dcPGS, P = .26), and death-censored kidney graft survival (dcKGS, P = .24) were similar between the sex-matched and sex-mismatched groups. Patient survival and dcPGS at 1, 5, and 15 years were 95.9%, 90.0%, and 62.1% and 86.1%, 77.1%, and 56.7% in the sex-matched group and 93.6%, 86.2%, and 62.4% and 83.1%, 73.3%, and 54.3% in the sex-mismatched group. Sex matching led to a lower odds of severe postoperative complications (41.2% vs 49.0%; OR 0.57, 95%CI 0.33-0.97; P = .038); however, no increased odds of other adverse postoperative outcomes was detected. CONCLUSION: Our study demonstrates that sex matching reduced the odds of postoperative complications but did not impact other early and late outcome parameters in our cohort.

ABSTRACT

BACKGROUND: Cardiovascular (CV) disease is the leading cause of death in kidney and simultaneous pancreas-kidney (SPK) transplant recipients. Assessing abdominal aortic calcification (AAC), using lateral spine x-rays and the Kaupilla 24-point AAC (0-24) score, may identify transplant recipients at higher CV risk. METHODS: Between the years 2000 and 2015, 413 kidney and 213 SPK first transplant recipients were scored for AAC at time of transplant and then followed for CV events (coronary heart, cerebrovascular, or peripheral vascular disease), graft-loss, and all-cause mortality. RESULTS: The mean age was 44 ± 12 years (SD) with 275 (44%) having AAC (26% moderate: 1-7 and 18% high: ≥8). After a median of 65 months (IQR 29-107 months), 46 recipients experienced CV events, 59 died, and 80 suffered graft loss. For each point increase in AAC, the unadjusted hazard ratios (HR) for CV events and mortality were 1.11 (95% CI 1.07-1.15) and 1.11 (1.08-1.15). These were similar after adjusting for age, gender, smoking, transplant type, dialysis vintage, and diabetes: aHR 1.07 (95% CI 1.02-1.12) and 1.09 (1.04-1.13). For recipients with high versus no AAC, the unadjusted and fully-adjusted HRs for CV events were 5.90 (2.90-12.02) and 3.51 (1.54-8.00), for deaths 5.39 (3.00-9.68) and 3.38 (1.71-6.70), and for graft loss 1.30 (0.75-2.28) and 1.94 (1.04-3.27) in age and smoking history-adjusted analyses. CONCLUSION: Kidney and SPK transplant recipients with high AAC have 3-fold higher CV and mortality risk and poorer graft outcomes than recipients without AAC. AAC scoring may be useful in assessing and targeted risk-lowering strategies.

ABSTRACT

BACKGROUND The pre-procurement pancreas suitability score (P-PASS) and the pancreas donor risk index (pDRI) are established predictive scores for graft survival and patient outcome following pancreatic transplantation. This retrospective study aimed to evaluate the predictive value of P-PASS and pDRI following simultaneous pancreas and kidney (SPK) transplantation, or pancreas after kidney (PAK) transplantation, and the clinical impact of donor-specific factors on the postoperative graft and recipient outcome at a single transplant center. MATERIAL AND METHODS The study included 105 patients who underwent SPK (n=104) or PAK (n=4) between 2000 and 2017. Donor-specific and recipient-specific parameters were recorded. Kaplan-Meier analysis and Cox regression analysis were used to assess the outcome after transplantation. RESULTS Overall, the mean 1-year and 5-year pancreas graft survival and patient survival rates were 78.7% and 93.2%, and 76.9% and 90.0%, respectively. The postoperative outcome in patients with a P-PASS score of <17 was not significantly different when compared with patients with a score of ≥17. A P-PASS score of ≥17 was significantly associated with early pancreas graft loss (p=0.04). There was no significant difference in postoperative outcome between patients with high pDRI and low pDRI. Smoking of donor (p=0.046) was a risk factor and coronary heart disease of recipient (p=0.003) had a significant effect on survival of pancreas graft. CONCLUSIONS This study showed that P-PASS and pDRI were not reliable predictors of outcome after pancreas transplantation and that specific characteristics of the donor and recipient must be evaluated when predicting the outcome of pancreas transplantation.

ABSTRACT

Transplant centers may decline an import pancreas offer based on demographics and laboratory test results, without information on actual gland quality. The relationship between position on the match run, indicative of the number of centers that chose not to use a pancreas, and patient and death-censored graft survival, is not known. We studied all 199 isolated pancreas grafts transplanted at the University of Wisconsin since July 2000 and compared overall patient and death-censored graft survival based on import vs local status. Of the 199 isolated pancreas transplants, 184 (92.5%) were imported from another donor service area with a median match rank of 49 (interquartile range 14-129). Median cold ischemia time was longer for imported pancreata (16.6 vs 13.4 hours, P = .02). In multivariate Cox modeling, there was no association with position on the rank list and patient (P = .44) or death-censored graft survival (P = .99). There was an overall rate of 6.5% of graft failure within 30 days; however, there was no association with position on the rank list and graft failure at 30 days (P = .33). Although the logistics may be challenging, sound judgment to accept offers independent of prior centers' decisions can result in quality utilization of imported pancreata.

ABSTRACT

Criteria for organ acceptance in brain-dead organ donors remain inconsistent, especially when concerning pancreatic transplants. We sought to examine donor-specific predictors of pancreatic graft use and survival to better guide the selection and management of potential donors. A prospective observational study of all donors from ten organ procurement organizations was conducted from March 2012 to January 2015. Critical care endpoints were collected at 4 standardized time points. Data associated with pancreatic transplantation and graft survival rates were first determined using univariate analyses, and then logistic regression was used to identify independent predictors of these two outcomes. From 1819 donors, 238 (13.1%) pancreata were transplanted, and at a mean follow-up of 192 days, 218 (91.6%) grafts had survived. After regression analysis, donor age (OR = 0.89), HgbA1C (OR = 0.07), and achieving the donor management goal (DMG) for ejection fraction at allocation of ≥50% (OR = 3.29) remained as independent predictors of pancreatic utilization. On regression analysis, graft survival was independently predicted by lower donor age (OR = 0.93) and achieving the DMGs for mean arterial pressure (60-110 mm Hg) and glucose (≤180 mg/dL) at separate time points. These results may help guide the management and selection of potential pancreatic donors after brain death.

ABSTRACT

BACKGROUND: Despite an increase in the number of pancreas transplants in the Scandiatransplant region in the last decade, there continues to be a gap between demand and supply of transplantable organs. This imbalance has encouraged the transplant community to consider new sources of grafts, such as the reintroduction of donors after circulatory death (DCD) who were the standard donors in our center before 1988. MATERIAL AND METHODS: In this long-term follow-up study, we compare 44 consecutive, simultaneous pancreas kidney transplants performed at Karolinska University Hospital between 1986 and 1991: 21 patients received DCD grafts and 23 received grafts from donors after brain death. RESULTS: Both groups had similar donor and recipient characteristics, but cold ischemia times were significantly shorter in the DCD group. Warm ischemia times were very short compared with other studies on DCDs. Patient and graft survival rates were similar in both groups. CONCLUSION: This study suggests that controlled DCD pancreas and kidney grafts transplanted simultaneously can be a feasible option for reducing organ shortage without any negative impact on the long-term results.
