Evaluation of the effects of n-acetylcysteine treatment in adult liver transplant recipients
Background: N-acetylcysteine (NAC) has been used in post-orthotopic liver transplant (OLT) patients for the proposed mechanism of preventing tissue damage of the newly transplanted organ from reactive oxygen species. This in turn may reduce cytokines and inflammation making oxygen delivery to the newly transplanted organ easier, which can lead to decreased reperfusion injury.
Objective: To evaluate the efficacy and safety of NAC use in patients post-OLT. Graft survival was examined as the primary outcome with post-operative bleeding requiring an exploratory laparotomy, biliary complications, and length of hospitalization.
Methods: The study is a retrospective review of the impact of NAC on solitary livers transplanted between January 2010 and June 2014. Student\u27s t-test was used to compare continuous variables and Chi-Square test was used to compare categorical variables. Kaplan-Meier Method and Cox Proportional Hazards model were used to analyze outcomes post-OLT.
Results:118 solitary livers were included with 50 (42%) receiving NAC post-OLT and 68 (58%) not receiving NAC. Those who received NAC had similar MELD at transplant, weight, age, and gender compared to those who did not. The average length of hospitalization post-OLT in the NAC group was 19.5 +/- 26.4 days vs. 14.1 +/- 11.0 days in the no NAC group (p=0.13.) Post-operative bleeding was similar between groups. A higher percent of those who received NAC had a DCD organ (32% vs. 15%, p=0.02). NAC patients had higher initial post-OLT AST and ALT compared to those who did not receive NAC (2604 +/- 1761 vs. 1192 +/- 1026, p
Conclusion: Further examination of association between biliary outcomes and NAC in a multivariable model also did not reach statistical significance. This could be due to our limited sample size, or overshadowed by more important variables like year of transplant or donor status. These results support the further need for research to fully understand the role of NAC use in post-operative liver transplant patients
En bloc Liver kidney transplantation using donor splenic artery as inflow to the kidney. Report of two cases
The number of simultaneous liver kidney transplant has been increasing. This surgery is associated with an increased risk of complications, longer duration of surgery and longer ischemia time to the renal allograft. Two patients listed for liver-kidney transplant at our center underwent en bloc combined liver kidney transplantation using donor splenic artery as inflow. Patient 1 previously underwent cardiac catheterization which was complicated by a bleeding pseudo-aneurysm of the right external iliac artery, which required endovascular stenting of the external iliac artery and embolization of the inferior epigastric artery. Patient 2 was on vasopressor support and continuous renal replacement therapy at the time of transplant. We describe a novel technique of en bloc liver-kidney transplant with simultaneous reperfusion of both allografts using the donor splenic artery for renal inflow. This technique is useful in decreasing cold ischemia time and total operative time by simultaneous reperfusion of both allografts. It is a useful technical variant which can be used in patients with severe disease of the iliac arteries. This article is protected by copyright. All rights reserved
Evaluation of vancomycin-resistant enterococci colonization and infection rates in adult liver transplant patients
Extracorpeal albumin dialysis with molecular adsorbent recirculating systems (MARS) and the effect on antimicrobial removal
Conclusion: Our recommendations for empiric antimicrobial dosing in MARS patients achieved adequate concentrations for the drugs sampled in our small patient population. Due to the observational study design, the potential impact on antimicrobial pharmacokinetics was not evaluated. Our investigation is ongoing in order to evaluate additional antimicrobials and the impact of more prolonged MARS runs. Additional data will be shared at Aurora Scientific Day
Evaluation of Preoperative Anemia and Transfusion Requirements in Adult Liver Transplant Recipients
Conclusion: Lower preoperative hemoglobin was associated with increased preoperative and intraoperative transfusion requirements as well as increased postoperative infection. More preoperative cryoprecipitate units, fewer postoperative cryoprecipitate units, and more FFP units were independent predictors of infection
