RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Klebsiella pneumoniae New Delhi metallo-beta-lactamase-1 (NDM-1) strains have recently become a new threat in kidney transplant recipients due to the strains' resistance to almost all antibiotics, including carbapenems. METHODS: We present a case series of 3 patients with urinary tract infections (UTIs) caused by multiresistant K pneumoniae NDM-1 strains who were treated with the same protocol. Genotyping sequencing with pulsed-field gel electrophoresis was performed in all cases. RESULTS: All patients were male and had undergone kidney transplantation 4, 7, and 8 months, respectively, before the admission. Combined antibiotic therapy consisting of imipenem/cilastatin in maximal doses, gentamicin and/or colistin for 21 to 27 days, followed by oral fosfomycin, was used in all cases. There were no further UTI episodes in 2 patients at the 12-month visit. Three months after initial treatment, the third patient presented with leukocyturia with no clinical symptoms and a urine culture positive for K pneumonia NDM-1 strain. Interestingly, the strain was susceptible to trimethoprim/sulfamethoxazole despite resistance in previous urine culture samples. The patient was successfully treated with trimethoprim/sulfamethoxazole 2 × 960 mg/d for 3 weeks followed by 480 mg/d and 3 doses of fosfomycin. Genotyping sequencing revealed identical DNA restriction fragments in bacterial strains from 2 patients. In the third case, although a difference in 2 restriction fragments was observed, the strain was considered related to the others. CONCLUSIONS: In cases of UTI caused by K pneumoniae NDM-1 strains, prolong combined treatment followed by oral fosfomycin prophylaxis can be successful. Strain genotyping should be performed to optimize further treatment protocols in such cases.

RESUMO

OBJECTIVE: Simultaneous pancreas and kidney transplantation (spktx) is the multiorgan transplantation. Thus various complications originated from transplanted organs and the complications that are not directly related to pancreatic or renal grafts could be developed at the same recipient. AIM: The aim of this study is to explore whether there is a correlation between the severity of complications originated from transplanted pancreas, transplanted kidney and general surgical complication developed at the same spktx recipient. METHODS: Complications which developed among 112 spktx recipients were divided into three groups: related to the pancreatic graft (PTXc), to the renal graft (KTXc) and the general surgical complication (GNc). Severity of postoperative complications using modified Dindo-Clavien scale recipients was evaluated for each group. The correlation of severity of coexisting complications from different complication groups was analyzed. RESULTS: There were 22 recipients who developed the coexistence of complication between different complication groups. Complication originated from two and three complication groups developed 15 (68.2%) and 7 (31.8%) patients, respectively. There was not found correlation of the complication severity between: KTXc and GNc group, GNc and PTXc group, KTXc and PTXc group. The correlation (r = 0.84) of complication severity in recipients who developed concurrently complication from transplanted kidney, transplanted pancreas and general surgery complication was found. CONCLUSION: The modified Dindo-Clavien scale is an useful methodology for the correlation description of complication severity in complex multiorgan transplantation such is spktx, especially when the complications originated from different, potentially independent from the pathophysiological point of view, sources.

RESUMO

BACKGROUND: Simultaneous pancreas and kidney transplantation (SPKTx) is the most commonly performed multiorgan transplantation procedure worldwide. Transplanted organs are the main source of complication; however, some postoperative complications are not directly related to the pancreatic or renal grafts. The goal of this study was to evaluate the prevalence, type, and severity of postoperative complications not related to transplanted kidney or pancreas among SPKTx recipients. METHODS: Complications unrelated to transplanted pancreas and kidneys among 112 SPKTx recipients were analyzed. The cumulative freedom from general surgical complications was assessed, and it was compared with cumulative freedom from complications related to kidney and pancreatic grafts. Severity of complications was classified according to a modified Clavien-Dindo scale. RESULTS: The general surgery complication rate was 22.2%. Cumulative freedom from general surgical complications at days 60 and 90 after transplantation was 0.89 and 0.87, respectively. Cumulative freedom from general surgical complications was comparable with cumulative freedom from complications related to kidney grafts but significantly higher than cumulative freedom from complications related to pancreatic grafts (log-rank test, P < .001). The rates for grades of severity II, IIIa, IIIb, and IVb were 19.4%, 9.7%, 64.5%, and 6.4%, respectively. The most frequent cause of complications was intra-abdominal hematoma or abscess (25.8%). CONCLUSIONS: The general surgical complication rate was comparable to the rate of complications originating from the renal grafts but significantly lower than the complication rate related to the transplanted pancreas. The incidence of general surgical complications could be defined as moderate, and the severity of this type of complication was low.

RESUMO

OBJECTIVE: Identification of factors that have an impact on postoperative complications after simultaneous pancreas and kidney transplantation (SPKTx) could help overcome limitations of this kind of treatment. METHODS: Postoperative complications among 112 SPKTx recipients were divided into 3 groups: related to transplanted pancreas (n = 66), related to transplanted kidney (n = 23) and general surgical complications (n = 31) 120 refers to complications among 112 recipients. According to the modified Clavien-Dindo scale, complications were classified according to their severity for each group. Risk factors for complication development related to donor, recipient, surgical technique, and immunosuppression were included to establish the multivariable model using logistic regression. RESULTS: Multiple regression analysis showed the following independent factors influenced mortal complications due to transplanted pancreas: age of donor (OR, 1.07; P < .04), duration of vascular pancreas anastomosis above 35 minutes (OR, 3.94; P < .04) and duration of recipient dialysis above 24 months before transplantation (OR, 0.14; P < .01). Area under receiver operating characteristic curve for this model was 0.8. CONCLUSION: To improve results, the following modification of identified risk factors should be assumed: selection of donor in term of age, shortening of the second warm ischemia time, and adjustment of the waiting list to avoid prolongation of recipient dialysis before SPKTx.

RESUMO

BACKGROUND: The high rate of complication after pancreas transplantation not only had an impact on recipient quality of life and survival but also had significant financial implications. Thus, monitoring transplant center performance was crucial to indentifying changes in clinical practice that result in quality deterioration. OBJECTIVE: To evaluate retrospectively the quality of the single, small pancreatic transplant program and to establish prospective monitoring of the center using risk-adjusted cumulative sum (CUSUM). METHODOLOGY: From 1988 to 2014, 119 simultaneous pancreas and the kidney transplantations (SPKTx) were performed. The program was divided into 3 eras, based on surgical technique and immunosuppression. Analyses of the 15 fatal outcomes due to complication from pancreatic graft were performed. The risk model was developed using multivariable logistic regression analysis based on retrospective data of 112 SPKTx recipients. The risk-adjusted 1-sided CUSUM chart was plotted for retrospective and prospective events. The upper control limit was set to 2. RESULTS: There were 2 main causes of death: multiorgan failure (73.3%; 11/15) and septic hemorrhage (26.7%; 4/15). Quality analysis using the CUSUM chart revealed that the process was not homogeneous; however, no significant signal of program deterioration was obtained and the performance of the whole program was within the settled control limit. CONCLUSION: For a single pancreatic transplant center. The risk-adjusted CUSUM chart was a useful tool for quality program assessment. It could support decision making during traditional surgical morbidity and mortality conferences. For small transplant centers, increasing the sensitivity of the CUSUM method by lowering the upper control limit should be considered. However, an individual assessment approach of the for particular centers is recommended.

RESUMO

OBJECTIVE: Simultaneous pancreas and kidney transplantation (SPKTx) is the most often performed multiorgan transplantation. The main source of complication is transplanted pancreas; as a result, early complications related to kidney transplant are rarely assessed. The aim of this study was to evaluate prevalence, types, and severity of postoperative complications due to kidney graft among the simultaneous pancreas and kidney recipients. METHODS: Complications related to transplanted kidney among 112 SPKTx recipients were analyzed. The indication for SPKTx was end-stage diabetic nephropathy due to long-lasting diabetes type 1. The cumulative survival rates for kidney graft function and cumulative freedom from complication on days 60 and 90 after transplantation were assessed. Severity of complications was classified according to the modified Dindo-Clavien scale. RESULTS: The 12-month cumulative survival rate for kidney graft was 0.91. Cumulative freedom from complication on the 60th day after transplantation was 0.84. The rates for II, IIIA, IIIB, IVA, and IVB severity grades were: 34.9%, 4.3%, 26.1%, 26.1%, and 8.6%, respectively. Acute tubular necrosis and rejection were the most frequent (43.4%) cause of complication. The most frequent reasons for graft nephrectomy were infections (2/7; 28.6%) and vascular thrombosis due to atherosclerosis of recipient iliac arteries (2/7; 28.6%). The most severe (IVB) complications were caused by fungal infection. CONCLUSION: Rate and severity of complications due to renal graft after SPKTx was low; however, to prevent the most serious ones reduction of fungal infection was necessary.

RESUMO

OBJECTIVE: Simultaneous pancreas and kidney transplantation (SPTKx) is characterized by the high rate and variability of postoperative complications, which could be a limitation of this treatment. The aim of this study was to evaluate prevalence, types, and severity of postoperative complications due to pancreas graft among the simultaneous pancreas and kidney recipients. METHODS: Postoperative complications related to transplanted pancreas among 112 SPTKx recipients were analyzed. The cumulative survival rates for pancreas graft function and cumulative freedom from complication on day 60 after transplantation were assessed. Severity of complications was classified according to a modified Clavien-Dindo scale. RESULTS: The 12-month cumulative survival rate for pancreatic graft was 0.74. Cumulative freedom from complication on the 60th day after transplantation was 0.57. The rates for II, IIIA, IIIB, IVA, and IVB severity grades were 10,6%, 4,5%, 19,7%, 44%, and 21,2%, respectively. The most severe (IVB) transplanted pancreas complications were due to graft inflammation, infection, pancreatic abscess, and local or diffuse necrosis. The most frequent reason for graft pancreatectomy was vascular thrombosis 35.9% (14/39). The mortality rate after graft pancreatectomy was significantly lower for vascular thrombosis than for infection (0/14 vs 11/25; P < .05). CONCLUSION: Reducing vascular thrombosis could preserve graft function rate. Preventing graft inflammation and infection would reduce mortality.

RESUMO

BACKGROUND: Thrombosis of the pancreatic graft vessels is a common complication in patients after pancreas transplantation. The aim of this study was to evaluate the usefulness of 16-multidetector computerized tomography (16-MDCT) with volume rendering (VR) and maximum intensity projection (MIP) reconstruction as a predicting method of pancreatic graft loss after simultaneous pancreas and kidney transplantation. METHODS: Within 6-8 days after combined kidney-pancreas transplantation, MDCT was performed in 60 patients. Secondary reconstructions were obtained with the application of VR and MIP algorithms. Vessel anastomosis, extra- and intrapancreatic arteries, venous morphology, and enhancement of graft's parenchyma were evaluated. The stenosis grade of pancreatic graft vessels and the areas of graft parenchyma malperfusion were evaluated. RESULTS: Thrombosis of pancreatic graft vessels was recognized in 26 patients (43%), however only one-half of them required graftectomy. There were 17 cases of large vessel thrombosis and 9 cases of small intragraft vessel thrombosis. In 13 (86.6%) out of 15 recipients parenchymal malperfusion resulted in graft lost. It appeared that vessel narrowing >40% was a threshold for pancreatic graft loss with sensitivity and false positive values of 100% and 9%, respectively. For parenchyma nonenhancement >60% the sensitivity and false positive values of 100% and 0% were significantly associated with pancreatic graft loss (P < .0001). CONCLUSIONS: Vascular occlusion of >40% and necrosis >60% of parenchymal volume correspond with pancreatic graft loss.

RESUMO

BACKGROUND: Atherosclerosis is common in end-stage renal disease patients on dialysis. However, it has previously been considered to be a relative contraindication to kidney transplantation. Currently, patients with extended indications are accepted onto the waiting list, including those with severe atherosclerosis. These patients require vascular procedures before or during kidney transplantation. The aim of this study was to present our experience with vascular reconstruction before kidney transplantation. MATERIAL AND METHODS: Twelve atherosclerotic, uremic patients referred to be candidates for kidney transplantation were refused because of occlusive lesions of the iliac arteries or the distal aorta. The 10 males and 2 females had an age range of 45 to 68 years. Preoperative assessments consisted of a Doppler ultrasound and an angio computed tomography scan. The reconstructions were performed with aorto-biliac, aorto-bifemoral, or ilio-femoral dacron grafts in 7, 4, and 1 patient, respectively, under general anesthesia. RESULTS: There were no major postoperative complications; the patients were discharged and placed on a special waiting list. Eight patients received kidney allografts, including one living-related transplantation. All procedures were performed with arterial anastomosis of the transplanted kidney to the side of the prosthesis. No patient developed signs of arterial graft infection. In the postoperative period, there were no arterial or transplanted kidney-related complications, except for delayed graft function in four cases. The remaining four patients are still on the waiting list. CONCLUSION: In end-stage renal disease patients with severe atherosclerosis in the aortoiliac region, vascular reconstruction allows kidney transplantation.

RESUMO

BACKGROUND: Simultaneous pancreas and preemptive kidney transplantation (SPpreKT) seems to be the optimal treatment for the patients with diabetes type 1 who are progressing to end-stage renal disease. On the other hand, surgical complications with a high rate of relaparatomy are a limiting factor in pancreas transplantation. OBJECTIVE: Comparison of severity of surgical complications was performed between a group of preemptive (SPpreKT group) and nonpreemptive recipients of SPKT (SPKT group). METHODS: Between 1988 and 2010, we performed 112 SPKTs including 25 preemptive recipients (22.3%). The SPKT Group included 87 recipients (77.7%). The severity of complications was classified according to a modified Clavien scale: grade I, no complication; grade II, drug therapy; grade IIIA, invasive intervention not requiring general anesthesia; grade IIIB, invasive intervention requiring general anesthesia; grade IVA, graft failure; and grade IVB, death. RESULTS: Among the SPpreKT group, 64% of recipients were free from postoperative complications compared with 40.3% of the SPKT group (P<.01). Among the SPKT group, 52 recipients (59.7%) developed 58 postoperative complications, including 15 (17.3%) deaths due to graft pancreatitis (80%) or pancreatic fistula (20%). Among the SPpreKT group, 9 recipients developed 9 complications. None of the preemptively transplanted group subjects experienced a lethal complication. Among the SPpreKT group, the most severe complication was graft pancreatitis leading to graft removal in 2 recipients. CONCLUSIONS: Recipients of preemptive SPKT developed significantly fewer postoperative complications, especially deaths. However the rates of mild (II, IIIA) and moderate (IIIB) complications as well as graft failures (IVA) were similar to the nonpreemptive group.

RESUMO

OBJECTIVES: Dialysis-dependent patients often have central venous drainage complications. In patients with functioning arm arteriovenous fistula, this may result in venous hypertension, arm oedema and vascular access failure. Percutaneous angioplasty and stent implantation might be inadequate to resolve these issues. In these cases, new access can potentially be created with anastomosis to the subclavian vein, iliac vein or vena cava or by making a veno-venous graft to bypass the thrombosis. The aim of this study was to assess the utility of unusual bypasses in vascular access in patients with the central vein thrombosis. MATERIALS: A total of 49 patients were treated. The mean number of previous vascular access surgery procedures was 7.6 (3-17). We performed 19 axillo-iliac, 14 axillo-axillary bypasses and 16 conduits from the arm fistula to the jugular (nine conduits) or subclavian (seven conduits) vein for haemodialysis purposes. RESULTS: All fistulas except one were used for haemodialysis. One patient died before the first use of the fistula. At 12 months, the primary, primary assisted and secondary patency rates were 85.4%, 89.6% and 95.8%, respectively. The follow-up period ranged from 1 to 84 months. CONCLUSION: Unusual grafts are an efficient option as a permanent vascular access for haemodialysis purposes in patients with central vein occlusion.

RESUMO

Thrombosis of the pancreatic graft vessels is the most common complication after transplantation. It leads to loss of 5% to 8% of grafts during the early postoperative period. The aims of this study were to evaluate the usefulness of 16-row multidetector computed tomography (16-MDCT) with volume rendering (VR) and maximum intensity projection (MIP) reconstruction to monitor pancreatic graft vessel patency during the early postoperative period and the efficacy of a heparin infusion as a treatment for graft thrombosis. Among 40 consecutive simultaneous pancreas-kidney transplant recipients, 16-MDCT was performed at 6 to 8 days after the operation. Secondary reconstructions were obtained with VR and MIP algorithms to evaluate the morphology and patency of the extra- and intrapancreatic arteries and veins. In cases of thrombosis, every patient was treated with an infusion of unfractionated heparin. In 15 recipients, thrombosis of the large vessels was detected by 16-MDCT. Heparin infusions saved five pancreatic grafts (5/15; 33.3%), but the other 10 pancreatic grafts were removed. In another four recipients (4/40; 10%) the thrombi were localized only in small intrapancreatic vessels. Treatment with heparin infusion was successful in 3/4 (75%) cases with patent vessels upon control computed tomography examination. We compared the efficacy of heparin treatment depending on the diameter of the thrombosed vessel, observing a significant difference (5/15 vs 3/4; P < .01; chi-square). 16-MDCT with secondary reconstruction by application of VR and MIP algorithms was an efficient method to visualize not only large pancreatic graft arteries and veins but also intrapancreatic parenchymal vessels. In cases of thrombosis of small intrapancreatic vessels, unfractionated heparin infusion significantly decreased graft loss.

RESUMO

Carbon monoxide (CO), well known from clinical observation to be a deadly poisoning gas, in many animal experiments has revealed a beneficial effect to diminish ischemia/reperfusion injury and rejection of transplanted organs. Data on clinical transplantation of organs retrieved from poisoned persons are limited and discordant; some authors were reported good results, whereas others described high complication rates including death. We herein have described a case of organ transplantation retrieved from a CO-poisoned donor. Warm ischemia during the transplantation procedure was prolonged to 100 minutes, but no complications were observed in the posttransplant course. This report may represent CO preconditioning in clinical transplantation.

RESUMO

The aim of this study was to evaluate long-term survival after simultaneous pancreas and kidney (SPK) transplantation in relation to function of both grafts. Among 67 recipients who received SPK transplants between 1988 and 2004, 35 had follow-up longer than 18 months, and were divided into: group I (n = 20), recipients with good function of both grafts; group II (n = 7), patients who had lost transplanted pancreas but had still good kidney graft function; group III (n = 8), patients who had lost both grafts. Comparison of survival rates and analysis of the reason of mortality among groups was performed. The cumulative survival rate was significantly higher in group I than in group III (after 3, 5, 10 years: 100%, 100%, 80% vs 75%, 50%, 37%, respectively). Cumulative survival rate for group II after 3, 5, 10 years was 100%, 100%, 33%, respectively. There were no significant differences in survival rates between groups I and II and between groups II and III. In group I deaths for cardiovascular event and for leukemia were noted. In group II deaths due to cardiovascular event and sepsis were observed. In group III all patients died due to cardiovascular events and the mean time from loss of pancreas and kidney graft function to death was: 75 +/- 51 months (range from 19 to 142), and 49 +/- 26 months (range 19 to 99), respectively. Good pancreas and kidney graft functions prevent death due to cardiovascular event.

RESUMO

The aim of this study was to evaluate the usefulness of 16-row multidetector computed tomography (16-MDCT) in the assessment of the potency of arterial and venous vessels in combined kidney-pancreas transplant and detection of transplant-related complications. Fifteen patients underwent a combined kidney-pancreatic transplantation. On the seventh day after the operation, we performed 16-MDCT in arterial and portal venous phase to evaluate vessels, anastomotic sites, and pancreatic parenchymal vascularization as well as peripancreatic fluid collections. We visualized the pancreatic vessels and anastomosis sites in all cases. In 12 recipients, there were no abnormal findings as regards the patency of the arterial and venous vessels and the vascularization of the pancreatic parenchyma. In two patients, complete arterial thrombosis of the body and tail pancreatic graft vessels was recognized at 2 weeks after transplantation, resulting in graft removal. Thrombi were localized in the distal part of anastomoses. None of the patients had venous thrombosis. One recipient had stenosis of the venous anastomosis. Peripancreatic fluid collections were observed in seven patients. In conclusion, 16-MDCT is an efficient method to estimate pancreatic transplant vessels, localize thrombi, and detect other transplant-related complications.

RESUMO

Multiorgan harvesting (MOH) accounts for approximately 40% of all organ procurements in Poland. Simultaneous procurement of the pancreas and liver necessitates division of the vessels supplying both organs. Therefore, reconstruction of the pancreas vasculature is mandatory for proper function of the transplanted organ. The aim of this study was to present various methods of vascular reconstruction to prepare the pancreas for transplantation. Between January 1999 and April 2005, among 42 whole pancreas transplantations, 35 came from MOH necessitating arterial reconstruction. In 32 cases, the splenic artery (SA) and superior mesenteric artery (SMA) were sewn into a single trunk using the common iliac arterial bifurcation. Occasionally, the iliac Y-graft was unsuitable for vascular reconstruction due to atherosclerosis or iatrogenic injury. Therefore, the SA was anastomosed to the side of the SMA in two cases. In one case we utilized the brachiocephalic trunk bifurcation. Portal vein elongation employed an external iliac vein procured from the donor in all 35 cases. Good perfusion was achieved in all transplanted pancreata. During the early follow-up period, two venous and one arterial thromboses were noted. No negative effects of pancreatic vessel reconstruction were observed in postoperative graft function. Reconstruction of the pancreas vasculature did not affect the long-term function of the allograft while significantly increasing the available donor organ pool.

RESUMO

It is well known that the main decrease in graft and recipient survival rates is observed during the first 12 months after transplantation. Improving results during this period seems to be crucial for the late outcome. The aim of this study was to compare 1-year survival rates of dialyzed and preemptive pancreas and renal graft recipients and their graft function. From November 1999 to January 2005, 42 whole simultaneous pancreas and kidney transplantations (spktx) were stratified into group I (n = 13): recipients who received a preemptive pancreas and kidney transplant versus group II (n = 29): previously dialyzed spktx recipients. The mean time of dialysis for group II was 39 +/- 16.5 months. We assessed 1-year cumulative survival rates for recipients and grafts for each group. The 1-year cumulative survival rate for preemptive graft recipients was significantly higher than that for dialyzed patients before spktx (100% vs 69%; P = .05). For groups I and II 1-year cumulative graft survival rates for kidney grafts were 100% and 89%, respectively, and for pancreatic grafts 84% and 65.5%, respectively. There was a significant improvement in the 1-year survival rate of preemptive spktx recipients compared with patients dialyzed before spktx. However, 1-year pancreas and kidney graft function did not differ significantly between the groups.

RESUMO

We present our experience with recombinant human activated protein C (rhAPC) to treat a 40-year-old preemptive simultaneous pancreas-kidney transplant (spktx) recipient who developed septic shock due to graft pancreatitis. We diagnosed intra-abdominal septic complications with septicemia induced by multiple pathogens and cardiopulmonary insufficiency. Until the 59th posttransplant day, 21 peritoneal lavages were performed to treat peritonitis and intra-abdominal abscesses. On the 53rd day when septic shock was diagnosed, rhAPC was administered, after which the patient improved, vasoconstrictive agents were reduced, and respiratory insufficiency resolved. The Physiologic and Operative Severity Score for enumeration of Mortality and Morbidity (POSSUM) scale showed a decrease in predicted mortality from 93% to 17% on day 7 after rhAPC initiation. The patient was discharged at 128 days after spktx with good function of both grafts. Administration of rhAPC limited systemic inflammatory response syndrome (SIRS) and may be considered when faced with the dilemma of stopping immunosuppression to save a recipient's life but at the cost of rejection of a functioning graft.
