OBJECTIVETo evaluate the incidence of surgical-site infections (SSIs) in a cohort of liver transplant recipients and to assess risk factors predisposing patients to these infections.DESIGNProspective observational cohort study.SETTINGSingle transplant center in Canada.PATIENTSPatients who underwent liver transplantation between February 2011 and August 2014.METHODSMultivariate logistic regression was used to identify independent risk factors for SSIs in liver transplant patients.RESULTSWe enrolled 250 liver transplant recipients. The recipients’ median age at the time of transplantation was 56 years (range, 19–70 years), and 166 patients (66.4%) were male. Moreover, 47 SSIs were documented in 43 patients (17.2%). Organ-space, superficial, and deep SSIs were noted in 29, 7, and 3 patients, respectively. In addition, 2 patients developed superficial and organ-space SSIs, and another 2 patients were found to have deep as well as organ-space infections. In total, we identified 33 organ-space SSIs (70.2%), 9 superficial SSIs (19.1%), and 5 deep SSIs (10.6%). Factors predictive of SSIs by multivariate analysis were duct-to-duct anastomosis (odds ratio [OR], 3.88; 95% CI, 1.85–8.13; P<.001) and dialysis (OR, 3.57; 95% CI, 1.02–12.50; P=.046). Of the 66 organisms isolated in both deep and organ-space SSIs, 55 (83%) were resistant to cefazolin.CONCLUSIONSOrgan-space SSIs are a common complication after liver transplantation. Duct-to-duct anastomosis and dialysis were independent risk factors associated with SSIs. Appropriate perioperative prophylaxis targeting patients with duct-to-duct anastomosis and dialysis while simultaneously providing optimum coverage for the potential pathogens causing SSIs is warranted.Infect Control Hosp Epidemiol 2017;38:1084–1090

Abstract Background Liver transplantation is considered to be the only curative treatment for patients with end stage liver disease. Postoperative infection remains to be one of the most common causes of morbidity and mortality throughout the past years. Cytomegalovirus (CMV) infection although considered to be a weak viral infection that usually passes asymptomatic in immunocompetent patients, however, it is considered one of the most common pathogens causing morbidities and mortality in liver transplant recipients. Multiple studies have been done to assess the risk factors for developing CMV infection. Objective Identification of risk factors predicting Cytomegalovirus infection in liver transplant recipients following transplantation. Methods This retrospective study was conducted on 194 patients and their donors who underwent living donor liver transplantation operation at Ain Shams centre for organ transplantation (ASCOT) at Ain Shams specialized hospital in the period between January 2010 and December 2016 with at least one year follow up period after operation for the recipient group. Results In our study, 194 patients undergoing liver transplantation at Ain shams centre for organ transplantation over seven years from January 2010 to December 2016 have been followed to assess risk factors affecting CMV infection development. Chronic rejection was found to be the most common factor associated with CMV infection followed by Cyclosporin (Neoral) as main postoperative immunosuppressant following liver transplantation. Other factors that were found to carry risk for CMV infection included younger age, advanced MELD score, positive CMV IgM status of the donors and recipients. Conclusion Differentiation of Cytomegalovirus disease from Cytomegalovirus infection isn’t always available as it requires tissue invasive techniques. Multiple risk factors have been attributed to cause Cytomegalovirus infection (viremia) . In our study, rejection (chronic rejection) was the factor that carries highest risk for Cytomegalovirus infection development followed by Cyclosporin .

Introduction: This was a single-center retrospective study to evaluate incidence, prognosis, and risk factors in patients with postoperative pleural effusions, a common pulmonary complication following liver transplantation. Methods: A retrospective review was performed on 374 liver transplantation cases through a database within the timeframe of January 1, 2009 through December 31, 2015. Demographics, pulmonary and cardiac function testing, laboratory studies, intraoperative transfusion/infusion volumes, postoperative management, and outcomes were analyzed. Results: In the immediate postoperative period, 189 (50.5%) developed pleural effusions following liver transplantation of which 145 (76.7%) resolved within 3 months. Those who developed pleural effusions demonstrated a lower fibrinogen (149.6 ± 66.3 mg/dL vs 178.4 ± 87.3 mg/dL; P = .009), total protein (5.8 ± 1.0 mg/dL vs 6.1 ± 1.2 mg/dL; P = .04), and hemoglobin (9.8 ± 1.8 mg/dL vs 10.3 ± 1.9 mg/dL; P = .004). There was not a statistically significant difference in 1-year all-cause mortality and in-hospital mortality between liver transplant recipients with and without pleural effusions. Liver transplant recipients who developed pleural effusions had a longer hospital length of stay (16.4 ± 10.9 days vs 14.0 ± 16.5 days; P = .1), but the differences were not statistically significant. However, there was a significant difference in tracheostomy rates (11.6% vs 5.4%; P = .03) in recipients who developed pleural effusions compared to recipients who did not. Conclusions: In summary, pleural effusions are common after liver transplantation and are associated with increased morbidity. Pre- and intraoperative risk factors can offer both predictive and prognostic value for post-transplantation pleural effusions. Further prospective studies will be needed to further evaluate the relevance of these findings to limit instances of postoperative pleural effusions.

Abstract Background and aims: Tenofovir disoproxil fumarate (TDF) and entecavir (ETV) have been recommended after liver transplantation to prevent recurrence of hepatitis B virus infection. Despite its proven efficacy, the renal safety of TDF has not been established in liver transplant recipients. We aimed to compare the effects of TDF and ETV on renal function in liver transplant recipients and to evaluate risk factors for renal dysfunction after liver transplantation. Methods: This is a retrospective, observational multicenter study of data from the Korean Organ Transplantation Registry. We included adults who underwent liver transplantation for hepatitis B virus-related complications from April 2014 to December 2017 and received TDF or ETV post-transplantation. Renal dysfunction was defined as an estimated glomerular filtration rate decline by at least 20% from baseline (1 month post-transplantation). Median duration of follow-up was 29 months (interquartile range 19–42).Results: A total of 804 liver transplant patients were included. The cumulative probability of renal dysfunction was significantly higher in the TDF group than in the ETV group. Multivariable analysis confirmed that TDF was independently associated with an increased risk of renal dysfunction (hazard ratio = 1.47, 95% confidence interval 1.12-1.92; P = 0.005). Independent risk factors for renal dysfunction included older age, worse baseline renal function, and low body mass index. Renal dysfunction after liver transplantation was independently associated with increased mortality.Conclusions: In this nationwide study, use of TDF was associated with an increased risk of renal dysfunction, when compared with ETV.

Introduction: The 2012 AHA/ACCF expert consensus statement regarding cardiac evaluation of liver transplant candidates specifies 7 risk factors for identifying candidates for cardiac evaluation prior to liver transplantation. These include age > 60 yrs, hypertension, diabetes, smoking, dyslipidemia, prior cardiovascular disease, and left ventricular hypertrophy. The prognostic value of these risk factors in predicting major adverse cardiac events (MACE) has not been established. Furthermore, the optimal threshold of the sum of risk factors to predict MACE has not been determined. Hypothesis: Risk factors set forth by the AHA/ACCF can predict MACE in liver transplant candidates. We sought to identify an optimal threshold sum of risk factors to predict MACE. Methods: We conducted a retrospective cohort study of consecutive liver transplant recipients who were followed for MACE, defined as a composite of cardiac death, myocardial infarction, or coronary revascularization. Kaplan-Meier plots, log-rank test, and Cox regression models were used in outcome analyses. Results: We retrospectively followed 193 consecutive liver transplant recipients (40% female, mean age 55±10 yrs) for a mean of 51±29 months, during which 24 MACE were observed. Having ≥2 AHA/ACCF risk factors was associated with increased MACE risk (HR, 2.75, P=0.02), whereas having ≥3 risk factors was associated with greater MACE risk (HR, 4.14, P<0.001), Figure 1. Using ≥1 risk factor threshold provided insignificant predictive value of event-free survival (P=0.29). Conclusion: This study provides prognostic validation of risk factors set forth by the AHA/ACCF consensus statement for cardiac evaluation in liver transplant candidates. Having ≥2 risk factors is most sensitive for predicting MACE and seems optimal for triggering CAD surveillance in asymptomatic liver transplant candidates.

Background: Surgical site infection is an important complication in the postoperative period among liver transplant recipients. However, little is known about the risk factors in this patient group. Therefore, the objective of this study was to analyze the incidence and risk factors for surgical site infections among adult liver transplant recipients. Methods: Medical records of adult liver transplant recipients from January 1, 2009, to December 31, 2015, were analyzed in this retrospective cohort study. Results: We enrolled 156 recipients’ medical records. Forty-two (26.9%) cases of surgical site infections were identified. The main isolated microorganisms were methicillin-resistant Staphylococcus species, extended spectrum β-lactamase-producing Klebsiella species, carbapenem-resistant Pseudomonas aeruginosa, carbapenem-resistant Acinetobacter baumannii, and vancomycin-susceptible Enterococcus faecalis. We found that long operative times (≥487 minutes) and differences in body mass index between donor and recipient (≥1.3 kg/m2) increased the risk for surgical site infections by approximately 5 times (odds ratio [OR], 5.5; 95% confidence interval [CI], 2.5-11.8), and capillary glycemia ≥175 mg/dL in the first 96 postoperative hours increased the risk by approximately 3 times (OR, 2.97; 95% CI, 1.43-6.17). Conclusions: There was a high incidence of surgical site infections among the studied population and that some risk factors identified differ from those reported in the scientific literature.
