Abstract
AIM Infection is a major cause of increased mortality after a liver transplant (LT). This study sought to identify the incidence, prevalence and risk factors of microbial infection for recipients who underwent LT using grafts from donors after cardiac death (DCD). METHODS We retrospectively analysed the frequency and characteristics of post-transplantation infections in 236 recipients who underwent DCD LT between 1 January 2010 and 31 December 2014 in our centre and evaluated the risk factors of post-transplantation infection. RESULTS Overall, 162 recipients acquired at least one type of infection during hospitalisation after LT, and the morbidity rate was 68.6%. Moreover, 19 of the 236 recipients died, with an overall mortality rate of 8.1%. In total, 752 pathogens were isolated. Gram-positive bacteria, Gram-negative bacteria and fungi accounted for 26.1% (196), 58.2% (438) and 15.7% (118) of the pathogens, respectively. Kaplan-Meier curves of 1-year survival showed that recipients with infection had a significantly lower cumulative survival rate compared with those without infection (83.2% vs. 90.6%, p < 0.05). Multivariate analysis revealed that age > 60 years (p = 0.010) and severe hepatitis (p = 0.036) were independent risk factors for infection during hospitalisation after LT. CONCLUSION Infection is a common complication after a DCD-LT that could impair 1-year survival. We suggest physicians pay more attention to the infection of recipients post-LT, especially those recipients greater than 60 years of age and those who suffered from severe hepatitis.

Abstract
OBJECTIVE To access the incidence of infectious problems after liver transplantation (LT). DESIGN A retrospective, single-center study. MATERIALS AND METHODS Patients undergoing LT from January 2008 to December 2011 were considered. Exclusion criterion was death occurring in the first 48 hours after LT. We determined the site of infection and the bacterial isolates and collected and compared recipient's variables, graft variables, surgical data, post-LT clinical data. RESULTS Of the 492 patients who underwent LT and the 463 considered for this study, 190 (Group 1, 41%) developed at least 1 infection, with 298 infections detected. Of these, 189 microorganisms were isolated, 81 (51%) gram-positive bacteria (most frequently Staphylococcus spp). Biliary infections were more frequent (mean time of 160.4 ± 167.7 days after LT); from 3 months after LT, gram-negative bacteria were observed (57%). Patients with infections after LT presented lower aminotransferase levels, but higher requirements in blood transfusions, intraoperative vasopressors, hemodialysis, and hospital stay. Operative and cold ischemia times were similar. CONCLUSION We found a 41% incidence of all infections in a 2-year follow-up after LT. Gram-positive bacteria were more frequent isolated; however, negative bacteria were commonly isolated later. Clinical data after LT were more relevant for the development of infections. Donors' variables should be considered in future analyses.

Abstract
BACKGROUND Liver transplantation is a complex surgery associated with high rates of postoperative complications. While national outcomes data are available, national rates of most complications are unknown. DATA SOURCES A systematic review of the literature reporting rates of postoperative complications between 2002 and 2012 was performed. A cohort of 29,227 deceased donor liver transplant recipients from 74 studies was used to calculate pooled incidences for 17 major postoperative complications. CONCLUSIONS This is the first comprehensive review of postoperative complications after liver transplantation and can serve as a guide for transplant and nontransplant clinicians. Efforts to collect national data on complications, such as through the National Surgical Quality Improvement Program, would improve the ability to provide patients with informed consent, serve as a tool for individual center performance monitoring, and provide a central source against which to measure interventions aimed at improving patient care.

Abstract
OBJECTIVE To explore the risk factors of intra-abdominal bacterial infection (IAI) after liver transplantation (LT) in patients with hepatocellular carcinoma (HCC). METHODS A series of 82 HCC patients who received LT surgeries in our department between March 2004 and April 2010 was recruited in this study. Then we collected and analyzed the clinical data retrospectively. Statistical analysis system (SPSS) software was adopted to perform statistical analysis. Chi-square test, t-test and Wilcoxon rank sum test were used to analyze the clinical data and compute the significance of the incidences of early-stage IAI after LT for HCC patients. Binary logistic regression was performed to screen out the risk factors, and multiple logistic regression analyses were performed to compute the independent risk factors. RESULTS A series of 13 patients (13/82, 15.9%) had postoperative IAI. The independent risk factors of postoperative intra-abdominal bacterial infections after LT for HCC patients were preoperative anemia [Hemoglobin (HGB) <90 g/L] and postoperative abdominal hemorrhage (72 hours >400 mL), with the odds ratios at 8.121 (95% CI, 1.417 to 46.550, P=0.019) and 5.911 (95% CI, 1.112 to 31.432, P=0.037). CONCLUSIONS Postoperative IAI after LT in patients with HCC was a common complication. Preoperative moderate to severe anemia, as well as postoperative intra-abdominal hemorrhage more than 400 mL within the first 72 hours might independently indicate high risk of IAI for these patients.

Abstract
OBJECTIVES Infection is the most severe complication after an organ transplant. Blood cell transfusion is an independent risk factor for adverse events, including infection in the recipient. This study sought to evaluate the effect of blood product transfusions on nosocomial infections in liver transplant patients. MATERIALS AND METHODS Patients who underwent a liver transplant at our hospital between 2003 and 2010 were recruited for this study. Exclusion criteria were incomplete records, patients who were hospitalized for more than 48 hours during the 4 weeks before transplant, and pediatric transplants. Incidence of nosocomial infections, which were defined as infections occurring within 30 days after transplant was the primary endpoint. RESULTS The incidence of nosocomial infections was 28.7%. The number of transfusions of packed red blood cells and fresh frozen plasma was significantly higher in patients with nosocomial infection compared with patients without nosocomial infection (P = .018 and P = .039). Blood products dose-dependently contributed to nosocomial infections. Transfusions of ≥ 7.5 units of red blood cells (odds ratio: 2.8) or ≥ 12.5 units of fresh frozen plasma (odds ratio: 3.27) were associated with nosocomial infections (P = .042 and P = .015). The infection-related mortality rate was 10.3%. CONCLUSIONS Blood product transfusions are associated with an increased rate of nosocomial infections, which contributes to higher morbidity and mortality.

Abstract
PURPOSE The purpose of the study was to assess the characteristics and risk factors of infections in the early period after orthopic liver transplantation (OLT) among adult patients. MATERIAL AND METHODS We studied 75 patients who underwent OLT over 3 years from 2008 to 2010. We recorded all infections that developed during hospitalization in the intensive care unit (ICU) their outcomes, and the possible risk factors. RESULTS During the study period in 80 OLT we recorded 19 bloodstream infections (47.5%), 7 ventilator-associated pneumonias (VAP; 17.5%), and 14 intra-abdominal infections (35%). Among the 40 isolated microbes, 72.5% were Gram negative, 25% were Gram positive, and 2.5% were fungi. The median time to developing the infection was 4.95 days (range 2-10). Patients with infections showed longer durations of mechanical ventilation, longer lengths of ICU stay, and lower 1-year survivals.

Abstract
INTRODUCTION We studied the influence of a broad range of genetic variants in recipient and donor innate immunity receptors on bacterial and fungal infections and acute rejection after liver transplantation (LT). METHODS Seventy-six polymorphisms in TLR 1-10, NOD2, LBP, CD14, MD2, SIGIRR, Ficolins 1, -2, and -3, MASP 1, -2, and -3, and the complement receptor C1qR1 were determined in 188 LT recipients and 135 of their donors. Associations with clinically significant infections and acute rejection were analyzed for 50 polymorphisms. Significant associations were validated in an independent cohort of 181 recipients and 167 donors. RESULTS Three recipient polymorphisms and 3 donor polymorphisms were associated with infections in the identification cohort, but none of these associations were confirmed in the validation cohort. Three donor polymorphisms were associated with acute rejection in the identification cohort, but not in the validation cohort. CONCLUSION In contrast to their effect in the general population, 50 common genetic variations in innate immunity receptors do not influence susceptibility to bacterial/fungal infections after LT. In addition, no reproducible associations with acute rejection after LT were observed. Likely, transplant-related factors play a superior role as risk factors for bacterial/fungal infections and acute rejection after LT.

Abstract
OBJECTIVE The high rate of early major infections in liver transplantation recipients is due to their compromised immune-system. We examined the risk factors of early major infection in living donor liver transplantation (LDLT). MATERIALS AND METHODS From January 2004 to December 2010, 242 patients undergoing LDLT were enrolled in the prospective cohort. We prospectively collected their clinical and demographic variables, operative details, and posttransplant complications. RESULT One hundred thirty-nine patients (57.7%) experienced 252 episodes of early infection posttransplantation: bloodstream septicemia (n = 46, 18.3%), urinary tract (n = 34; 14.1%), pneumonia (n = 64; 25.4%), peritonitis (n = 62; 25.7%), and catheter related (n = 46; 19%). The most frequent Gram-positive bacteria were coagulase-negative staphylococci (n = 52; 16.9%), followed by Staphylococcus aureus (n = 32; 10.4%). The most common Gram-negative bacteria were Escherichia coli (n = 27; 8.8%); Acinetobacter baumannii (n = 29; 9.4%), Pseudomonas aureos (n = 18; 5.8%), and Sternotrophomonas maltophilia (n = 18; 5.8%). Upon multivariate logistic regression analysis, the risk factors for early major infection were a high creatinine level (odds ratio = 1.481), a long anhepatic arterial phase (1.01), a reoperation (6.417), young age (1.040), and non-hepatocellular carcinoma recipient (2.141). CONCLUSION Early major infection after LDLT was high with Gram-positive bacteria, the most common etiologies. Prolonged anhepatic arterial phase, renal insufficiency, and reoperation were risk factors for an early major infection.

Abstract
Clinically significant infections (CSIs) are life-threatening but difficult to diagnose after liver transplantation (LTx). This study investigates the value of procalcitonin (PCT) in addition to c-reactive protein (CRP) and the leukocyte count (LC) as a prognostic marker for CSIs in LTx recipients. The clinical course of 135 LTx recipients was prospectively studied. CSIs were defined as pulmonary, bloodstream, or intra-abdominal infections. Independent risk factors for CSIs were determined by Cox proportional hazard analysis. The concordance statistics (c-statistics) were used to assess the discrimination effect of PCT. Thirty recipients (22%) experienced a CSI. They had significantly higher peak PCT (27.2 versus 12.7 ng/mL, P = 0.014) and peak CRP (13.7 versus 9.9 mg/dL, P < 0.001) and a tendency toward a higher peak LC (19.3 versus 14.2 cells/nL, P = 0.051) in comparison with recipients without CSIs. Independent risk factors for CSIs were male sex [hazard ratio (HR) = 6.4], a body mass index (BMI) < 20 kg/m(2) (versus a BMI > 25 kg/m(2), HR = 13.8), acute liver failure as an indication for LTx (HR = 7.1), a cold ischemic time > 420 minutes (HR = 3.5), and peak CRP (HR = 1.1) but not peak PCT. The addition of peak PCT marginally improved the c-statistic from 0.815 to 0.827. In conclusion, although peak PCT differed significantly between recipients with and without CSIs, it was not an independent risk factor for CSIs and added little prognostic accuracy. Interestingly, the parameters peak CRP, male sex, low BMI, acute liver failure, and long cold ischemic time were independent risk factors for CSIs. They could serve as risk stratifiers directing medical therapy in clinical practice.

Abstract
AIM: To evaluate the efficacy of granulocyte colony stimulating factors (G-CSF) in liver transplanted patients with hepatitis C (HCV) recurrence and Pegylated-IFN α-2b induced neutropenia, and to evaluate the impact of G-CSF administration on virological response.
METHODS: Sixty-eight patients undergoing antiviral treatment for post-liver transplantation (OLT) HCV recurrence were enrolled. All patients developing neutropenia received G-CSF.
RESULTS: Twenty three (34%) received G-CSF. Mean neutrophil count at the onset of neutropenia was 700/mmc (range 400-750/mmc); after 1 mo of G-CSF it increased to 1210/mmc (range 300-5590/mmc) (P < 0.0001). Three patients did not respond to G-CSF. Treatment duration was similar in neutropenic and non-neutropenic patients. No differences in the rate of discontinuation, infections or virological response were observed between the two groups. G-CSF was protective for the onset of de novo autoimmune hepatitis (P < 0.003).
CONCLUSION: G-CSF administration is effective in the case of Peg-IFN induced neutropenia increasing neutrophil count, prolonging treatment and leading to sustained virological response (SVR) rates comparable to non-neutropenic patients. It prevents the occurrence of de novo autoimmune hepatitis.

Abstract
BACKGROUND Primary opportunistic deep cutaneous fungal infections may cause significant morbidity and mortality in solid organ transplant recipients (OTR), but no data exist about their incidence, timing, and clinical predictors in a long-term follow-up. PATIENTS AND METHODS A series of 3293 consecutive OTR including 1991 kidney, 929 heart, and 373 liver transplant recipients were enrolled. Patients were regularly followed up since time at transplantation (mean 5.5 yr +/-5.9 SD) and primary opportunistic fungal infections registered. Persons-year at risk (PYs), incidence rates (IR), incidence rate ratios (IRR), and 95% confidence intervals were computed. RESULTS Twenty-two cases of deep cutaneous mycoses were detected, (IR 1.2 cases per 1000 PYs) after a mean follow-up time since transplantation of 2.5 yr +/- 2.0 SD (median 1.8 yr). Six patients had subsequent systemic involvement and three patients died of systemic dissemination. A higher risk for mycoses was observed in the first two yr after transplantation, (IRR 35.9, p < 0.0001), in renal transplant recipients (IRR 5.1 p = 0.030), and in patients transplanted after the age of 50 (IRR 11.5 p = 0.020). CONCLUSIONS Primary deep cutaneous opportunistic mycoses in OTR occur mainly in the first two yr after transplantation, in renal transplant recipients, and in older patients.
