Long-term Outcomes in Simultaneous Pancreas-Kidney Transplant Recipients: Single-center Experience From Poland.

BACKGROUND: Simultaneous pancreas-kidney transplantation (SPKT) is the treatment of choice for patients with end-stage renal disease (ESRD) due to type 1 diabetes mellitus (DM1). Since the 1980s, pancreas transplantation has become the most effective strategy to restore normoglycemia in patients with DM1. The aim of this study was to present long-term outcomes data for SPKT. METHODS: We performed a retrospective analysis of 73 SPKT recipients followed in our outpatient center who underwent transplantation between 1988 and 2015. RESULTS: A total of 50.7% of the patients were male. At the time of surgery, patients' mean age was 37.38 ± 7.44 years. Patients were diagnosed with DM1 at an average of 25 ± 6.08 years before SPKT. For 21.9% of patients, the transplant was done preemptively. Most (91.8%) had enteric drainage. All patients received induction of immunosuppression (either polyclonal immunoglobulins anti-thymocyte globulin or thymoglobulin [64.4%] or monoclonal globulins daclizumab or basiliximab [35.6%]). Patient survival at 1, 5, 10, 15 years was 99%, 97%, 89%, and 75%; kidney survival was 99%, 96%, 84%, and 67%; and pancreas survival was 95%, 92%, 84%, and 64%, respectively. There was a notable tendency toward increased creatinine level (from 1.18 at 1 year to 1.78 at 15 years) and decreased hemoglobin level (from 13.84 at 1 year to 12.65 at 15 years). CONCLUSION: Diabetic patients with ESRD have a poor prognosis without transplantation. SPKT provides marked prolongation of the patient's life and freedom from insulin injections. Enteric drainage is currently the surgical technique of choice. SPKT should remain as the treatment of choice in this patient population.

Analysis of Hospitalizations in Simultaneous Pancreas-Kidney Transplant Recipients: A Single-center Experience in Poland.

BACKGROUND: End-stage renal disease due to type 1 diabetes mellitus appears to be a regular indication for simultaneous pancreas and kidney transplantation (SPKT). Although transplantation improves a patient's health condition, it does not mean that all complications will be eliminated. METHODS: We performed a retrospective analysis of 73 patients who underwent SPKT and follow-up between 1988 and 2015 at our institute. The number, duration, and reasons for hospitalization at 1, 5, 10, and 15 years after SPKT were analyzed. RESULTS: The average number of hospitalizations at 1, 5, 10, 15 years after SPKT were 1.66, 0.39, 0.36, and 0.33, respectively. The main reason for hospitalization over the 15-year period was infections, at 32.4% (SD, 6.8%). Within the first year after SPKT, 6.8% of hospital admissions were caused by cytomegalovirus (CMV) infection. Over time, the percentage of hospitalizations for cardiovascular complications increased from 0.6% at 1 year to 29% at 12-15 years. Incidence of hospitalization due to cardiovascular complications correlated with a longer period of dialysis and a diagnosis of ischemic heart disease before transplant (r = 0.56, P = .004; r = 0.54, P < .0001, respectively). At 12-15 years after transplantation, 18.2% of hospitalizations were caused by secondary complications of diabetes. CONCLUSION: The most common reason for hospitalization after SPKT is infectious complications. In the first year posttransplant, there is a high percentage of CMV infections. Hospitalization associated with cardiovascular complications was found to be most common in the latter follow-up period and showed a correlation with longer dialysis period.

Analysis of Distribution of Expanded- and Standard-Criteria Donors and Complications Among Polish Recipients by Kidney Donor Risk Index Value.

INTRODUCTION: The approach toward transplanting kidneys from expanded-criteria donors (ECDs) in Poland is largely site-dependent. The Kidney Donor Risk Index (KDRI) allows for obtaining a more precise characteristic of ECDs and further stratification into "better" and "worse" quality grafts. METHODS: Comparison of the incidence of delayed graft function (DGF) and biopsy-proven acute rejection (BPAR), median of hospitalization time and median of estimated glomerular filtration rate (eGFR) at 1 year after transplantation among kidney graft recipients (n = 468), divided by donor status (ECD/standard-criteria donor [SCD]) and KDRI value (I: 0.67-1.2, II: 1.21-1.6, III: 1.61-2.0, IV: 2.01-3.48). RESULTS: ECD kidneys have been transplanted to 32.47% of recipients. There were no ECD recipients in KDRI compartment I, 16.55% in compartment II, 79.22% in compartment III, and 100% in IV. In KDRI compartment II, DGF was diagnosed in 34.9% of SCDs and 56% of ECDs (P = .003), BPAR occurred in 7.8% of SCDs and 16% of ECDs (P = .073), median hospital stay was 12 days for SCDs and ECDs (P = 1), and eGFR was 50.7 mL/min for SCDs and 49.4 mL/min for ECDs (P = .734). In KDRI compartment III, DGF was diagnosed in 43.8% of SCDs and 49.2% of ECDs (P = .139), BPAR occurred in 6.3% of SCDs and 31.7% of ECDs (P = .001), median hospital stay was 10 days for SCDs and 12 days for ECDs (P = .634), and eGFR was 49.5 mL/min for SCDs and 45.2 mL/min for ECDs (P = .382). Among ECD recipients, DGF was diagnosed in 56.0%, 49.2%, and 47.7% of patients for KDRI compartments II, III, and IV respectively (P = .776); BPAR occurred in 16% (compartment II), 31.7% (compartment III), and 23.1% (compartment IV) (P = .273); the median hospital stay was 12 days (compartment II), 12 days (compartment III), and 12.5 days (compartment IV) (P = 1); and eGFR was 49.5 mL/min (compartment II), 45.4 mL/min (compartment III), and 36.1 mL/min (compartment IV) (P = .002). CONCLUSION: Assessment using both the ECD and KDRI systems allows for a more precise evaluation of prognosis and predicting complications among recipients.
