Aging with a Liver Graft: Analysis of Very Long-Term Survivors after Liver Transplantation.

BACKGROUND: In Italy, data on long-term survivors after liver transplantation are lacking. MATERIALS AND METHODS: We conducted a hybrid design study on a cohort of 359 adult recipients who received transplants between 1996 and 2002 to identify predictors of survival and the prevalence of co-morbidities among long-term survivors. RESULTS: The actuarial (95% CI) patient survival was 96% (94.6-98.3%), 69% (64.2-73.6%), 55% (49.8-59.9%), 42.8% (37.6-47.8%), and 34% (29.2-38.9%) at 1, 5, 10, 15, and 20 years, respectively. The leading causes of death were hepatitis C virus recurrence (24.6%), extrahepatic malignancies (16.9%), infection (14.4%), and hepatocellular carcinoma recurrence (14.4%). The factors associated with the survival probability were younger donor and recipient ages (p = 0.001 and 0.004, respectively), female recipient sex (p < 0.001), absence of HCV (p < 0.01), absence of HCC (p = 0.001), and absence of diabetes mellitus at one year (p < 0.01). At the latest follow-up, the leading comorbidities were hypertension (53.6%), obesity (18.7%), diabetes mellitus (17.1%), hyperlipidemia (14.7%), chronic kidney dysfunction (14.7%), and extrahepatic malignancies (13.8%), with 73.9% of patients having more than one complication. CONCLUSIONS: Aging with a liver graft is associated with an increased risk of complications and requires ongoing care to reduce the long-term attrition rate resulting from chronic immunosuppression.

First-in-human liver transplantation from a centenarian deceased donor after brain death.

Liver transplantation from elderly donors is expanding due to demand for liver grafts, aging of recipients and donors, and introduction of machine perfusion. We report on a liver transplant from a 100-year-old deceased donor after brain death. The liver was transplanted after the use of hypothermic machine perfusion to a 60-year-old recipient with advanced hepatocellular carcinoma undergoing neoadjuvant immunotherapy. Nine months after the transplant, the patient is alive with a functioning graft and no evidence of acute rejection or tumor recurrence.

Additional modifications to the Blumgart pancreaticojejunostomy: Results of a propensity score-matched analysis versus Cattel-Warren pancreaticojejunostomy.

BACKGROUND: Postoperative pancreatic fistula continues to occur frequently after pancreatoduodenectomy. METHODS: We have described a modification of the Blumgart pancreaticojejunostomy. The modification of the Blumgart pancreaticojejunostomy was compared to the Cattel-Warren pancreaticojejunostomy in cohorts of patients matched by propensity scores based on factors predictive of clinically relevant postoperative pancreatic fistula, which was the primary endpoint of this study. Based on a noninferiority study design, 95 open pancreatoduodenectomies per group were needed. Feasibility of the modification of the Blumgart pancreaticojejunostomy in robotic pancreatoduodenectomy was also shown. All pancreaticojejunostomies were performed by a single surgeon. RESULTS: Between October 2011 and May 2019, there were 415 pancreatoduodenectomies with either a Cattel-Warren pancreaticojejunostomy (n = 225) or a modification of the Blumgart pancreaticojejunostomy (n = 190). There was 1 grade C postoperative pancreatic fistula in 190 consecutive modification of the Blumgart pancreaticojejunostomies (0.5%). Logistic regression analysis showed that the rate of clinically relevant postoperative pancreatic fistula was not affected by consecutive case number. After exclusion of robotic pancreatoduodenectomies (the Cattel-Warren pancreaticojejunostomy: 82; modification of the Blumgart pancreaticojejunostomy: 66), 267 open pancreatoduodenectomies were left, among which the matching process identified 109 pairs. The modification of the Blumgart pancreaticojejunostomy was shown to be noninferior to the Cattel-Warren pancreaticojejunostomy with respect to clinically relevant postoperative pancreatic fistula (11.9% vs 22.9%; odds ratio: 0.46 [0.21-0.93]; P = .03), grade B postoperative pancreatic fistula (11.9% vs 18.3%; P = .18), and grade C postoperative pancreatic fistula (0 vs 4.6%; P = .05) as well as to all secondary study endpoints. The modification of the Blumgart pancreaticojejunostomy was feasible in 66 robotic pancreatoduodenectomies. In this subgroup with 1 conversion to open surgery (1.5%), a clinically relevant postoperative pancreatic fistula occurred after 9 procedures (13.6%) with no case of grade C postoperative pancreatic fistula and a 90-day mortality of 3%. CONCLUSION: The modification of the Blumgart pancreaticojejunostomy described herein is noninferior to the Cattel-Warren pancreaticojejunostomy in open pancreatoduodenectomy. This technique is also feasible in robotic pancreatoduodenectomy.

Viremia Negativization After BK Virus Infection in Kidney Transplantation: A National Bicentric Study.

BACKGROUND: BK virus (BKV) infection represents a potentially dreadful complication after kidney transplantation (KT). When BK viremia is detected, the best therapeutic approach remains not entirely clarified. Critical elements of BK viremia treatment are immunosuppression minimization and introduction of drugs like leflunomide, everolimus, and fluoroquinolones. The study aimed to analyze the results of the BK viremia management in 2 collaborative Italian centers. METHODS: Ten patients undergoing KT in the 2 collaborative Italian centers of Sapienza University of Rome and University of L'Aquila from January 2013 to December 2017 and showing a post-KT diagnosis of BK viremia were retrospectively investigated. RESULTS: Mean time from KT to BKV positivity was 7 months (range: 1-19 months). At diagnosis, the mean viral load was 683,842 copies/mL (range: 5800-4,052,415 copies/mL), with an average zenith of 2,428,410 copies/mL (range: 6762-18,022,500 copies/mL). In the 5 patients with BKV nephropathy, we observed a switch from antimetabolite to leflunomide (n = 5), a switch from tacrolimus to everolimus (n = 3), or an introduction of fluoroquinolones (n = 3). BKV clearance was achieved in 3 patients. CONCLUSIONS: Early BKV diagnosis and stepwise minimization of immunosuppression remain the first-line approach in patients with BK viremia. In the presence of BKV nephropathy, a combination of antiviral drugs like leflunomide and fluoroquinolones/everolimus should favor viremia clearance.
