Item Donor Simvastatin Treatment Is Safe and Might Improve Outcomes After Liver Transplantation: A Randomized Clinical Trial(Wolters Kluwer, 2022) Pagano, Duilio; Bosch, Jaime; Tuzzolino, Fabio; Oliva, Elisabetta; Ekser, Burcin; Zito, Giovanni; Cintorino, Davide; di Francesco, Fabrizio; Petri, Sergio Li; Ricotta, Calogero; Bonsignore, Pasquale; Calamia, Sergio; Magro, Bianca; Trifirò, Gianluca; Alduino, Rossella; Barbara, Marco; Conaldi, Pier Giulio; Gallo, Alessia; Venuti, Francesca; Luca, Angelo; Gruttadauria, Salvatore; Surgery, School of MedicineBackground: The current curative approaches for ischemia/reperfusion injury on liver transplantation are still under debate for their safety and efficacy in patients with end-stage liver disease. We present the SIMVA statin donor treatment before Liver Transplants study. Methods: SIMVA statin donor treatment before Liver Transplants is a monocentric, double-blind, randomized, prospective trial aiming to compare the safety and efficacy of preoperative brain-dead donors' treatment with the intragastric administration of 80 mg of simvastatin on liver transplant recipient outcomes in a real-life setting. Primary aim was incidence of patient and graft survival at 90 and 180 d posttransplant; secondary end-points were severe complications. Results: The trial enrolled 58 adult patients (18-65 y old). The minimum follow-up was 6 mo. No patient or graft was lost at 90 or 180 d in the experimental group (n = 28), whereas patient/graft survival were 93.1% ( P = 0.016) and 89.66% ( P = 0.080) at 90 d and 86.21% ( P = 0.041) and 86.2% ( P = 0.041) at 180 d in the control group (n = 29). The percentage of patients with severe complications (Clavien-Dindo ≥IIIb) was higher in the control group, 55.2% versus 25.0% in the experimental group ( P = 0.0307). The only significant difference in liver tests was a significantly higher gamma-glutamyl transferase and alkaline phosphatase at 15 d ( P = 0.017), ( P = 0.015) in the simvastatin group. Conclusions: Donor simvastatin treatment is safe, and may significantly improve early graft and patient survival after liver transplantation, although further research is mandatory.Item Vasopressin for Post-kidney Transplant Hypotension(Elsevier, 2022-04-07) Jan, Muhammad Y.; Moe, Sharon M.; Adebiyi, Oluwafisayo; Chen, Jeannie; Powelson, John; Burney, Heather N.; Yaqub, Muhammad S.; Mishler, Dennis P.; Moorthi, Ranjani N.; Taber, Tim E.; Anderson, Melissa D.; Li, Yang; Li, Xiaochun; Fridell, Jonathan A.; Goggins, William C.; Sharfuddin, Asif A.; Medicine, School of MedicineIntroduction: Hypotension after deceased donor kidney transplant (DDKT) is a risk factor for delayed graft function (DGF) and poor graft survival (GS). We hypothesize that vasopressin use in hypotensive DDKT recipients (DDKTRs) to increase blood pressure (BP) reduces DGF rates and is safe without increasing mortality. Methods: Group with vasopressin "study group" (n = 45) was defined as DDKTRs between 2012 and 2017 who required vasopressin for hypotension systolic BP (SBP) <120 mm Hg or diastolic BP (DBP) <60 mm Hg. DDKTRs with no-vasopressin "comparison group" (n = 90) were propensity score-matched DDKTRs between 2012 and 2017 without vasopressin use. Primary outcomes were GS, creatinine and allograft biopsy rate at 1 year, DGF rate, and death during transplant hospitalization. Results: Vasopressin group had lower mean maximum and minimum SBP and DBP in the operating room (OR). Median vasopressin start time post-DDKT was 2 hours (interquartile range [IQR] 1-6), and duration of use was 42 hours (IQR 24-63). DGF, creatinine at 1 year, and allograft biopsy rates were comparable. No deaths occurred during transplant hospitalization. Multivariable analysis did not find an effect of vasopressin use on GS. Conclusion: Treatment of hypotensive DDKTRs with vasopressin is safe and facilitated similar graft function and survival with that of nonhypotensive patients. In the absence of a randomized control trial, our study supports the safety of vasopressin therapy to prevent the adverse effects of hypotension.
