    Efficacy and safety of antifibrinolytic drugs in liver transplantation: a systematic review and meta-analysis. Molenaar I Q,Warnaar N,Groen H,Tenvergert E M,Slooff M J H,Porte R J American journal of transplantation : official journal of the American Society of Transplantation and the American Society of Transplant Surgeons Although several randomized controlled trials (RCTs) have shown the efficacy of antifibrinolytic drugs in liver transplantation, their use remains debated due to concern for thromboembolic complications. None of the reported RCTs has shown a higher incidence of these complications in treated patients; however, none of the individual studies has been large enough to elucidate this issue completely. We therefore performed a systematic review and meta-analysis of efficacy and safety endpoints in all published controlled clinical trials on the use of antifibrinolytic drugs in liver transplantation. Studies were included if antifibrinolytic drugs (epsilon-aminocaproic acid, tranexamic acid (TA) or aprotinin) were compared with each other or with controls/placebo. Intraoperative red blood cell and fresh frozen plasma requirements, the perioperative incidence of hepatic artery thrombosis, venous thromboembolic events and mortality were analyzed. We identified 23 studies with a total of 1407 patients which met the inclusion criteria. Aprotinin and TA both reduced transfusion requirements compared with controls. No increased risk for hepatic artery thrombosis, venous thromboembolic events or perioperative mortality was observed for any of the investigated drugs. This systematic review and meta-analysis does not provide evidence for an increased risk of thromboembolic events associated with antifibrinolytic drugs in liver transplantation. 10.1111/j.1600-6143.2006.01591.x
    The Safety and Efficacy of Lysine Analogues in Cancer Patients: A Systematic Review and Meta-Analysis. Montroy Joshua,Fergusson Nicholas A,Hutton Brian,Lavallée Luke T,Morash Chris,Cagiannos Ilias,Cnossen Sonya,Fergusson Dean A,Breau Rodney H Transfusion medicine reviews Lysine analogues are effective agents used for the reduction of blood loss and transfusion. However, the safety of lysine analogues in cancer patients remains in question due to a potential risk of venous thromboembolism (VTE). The objective of our review is to investigate safety and efficacy of lysine analogue administration in the patients with cancer. Medline, Embase, and The Cochrane Library were searched from inception to June, 2016. Reference lists of retrieved studies were searched to identify additional publications. We included randomized clinical trials in adult cancer patients for which a lysine analogue was administered for the purpose of blood loss reduction. Abstract and full-text selection as well as data extraction and risk of bias assessment was done by 2 independent reviewers. The primary outcome was venous thromboembolic events. Secondary outcomes were other adverse events, blood transfusion, and blood loss. Overall, 11studies involving 1177 patients evaluated at least one of the primary or secondary outcomes. Nine studies evaluated the effects of tranexamic acid, one study evaluated the effects of aminocaproic acid and one study examined both agents. No increased risk of venous thromboembolism was observed for patients who received lysine analogues compared to control (Peto OR 0.58; 95% CI 0.26-1.28). The administration of a lysine analogue significantly decreased both transfusion risk (pooled RR 0.52, 95% CI 0.34-0.80) and blood loss (SMD -1.57, 95% CI -2.21 to -0.92). Among 3 eligible studies, no increased risk was observed for mortality (Peto OR 1.01; 95% CI 0.14-7.18) or infection (OR 0.58; 95% CI 0.27-1.27). The safety of lysine analogues in cancer patients has not been extensively studied. Based on the available literature, lysine analogue use has not been associated with increased risk of venous thromboembolism or other adverse events, while being effective in reducing blood loss and subsequent transfusion. 10.1016/j.tmrv.2017.03.002
    Epsilon-Aminocaproic Acid Has No Association With Thromboembolic Complications, Renal Failure, or Mortality After Liver Transplantation. Nicolau-Raducu Ramona,Ku Timothy C,Ganier Donald R,Evans Brian M,Koveleskie Joseph,Daly William J,Fish Brian,Cohen Ari J,Reichman Trevor W,Bohorquez Humberto E,Bruce David S,Carmody Ian C,Loss George E,Gitman Marina,Marshall Thomas,Nossaman Bobby D Journal of cardiothoracic and vascular anesthesia OBJECTIVES:To examine the role of epsilon-aminocaproic acid (EACA) administered after reperfusion of the donor liver in the incidences of thromboembolic events and acute kidney injury within 30 days after orthotopic liver transplantation. One-year survival rates between the EACA-treated and EACA-nontreated groups also were examined. DESIGN:Retrospective, observational, cohort study design. SETTING:Single-center, university hospital. PARTICIPANTS:The study included 708 adult liver transplantations performed from 2008 to 2013. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:EACA administration was not associated with incidences of intracardiac thrombosis/pulmonary embolism (1.3%) or intraoperative death (0.6%). Logistic regression (n = 708) revealed 2 independent risk factors associated with myocardial ischemia (age and pre-transplant vasopressor use) and 8 risk factors associated with the need for post-transplant dialysis (age, female sex, redo orthotopic liver transplantation, preoperative sodium level, pre-transplant acute kidney injury or dialysis, platelet transfusion, and re-exploration within the first week after transplant); EACA was not identified as a risk factor for either outcome. One-year survival rates were similar between groups: 92% in EACA-treated group versus 93% in the EACA-nontreated group. CONCLUSIONS:The antifibrinolytic, EACA, was not associated with an increased incidence of thromboembolic complications or postoperative acute kidney injury, and it did not alter 1-year survival after liver transplantation. 10.1053/j.jvca.2015.12.003
