Abstract
BACKGROUND Liver transplantation is increasing worldwide with underlying pathologies dominated by metabolic and alcoholic diseases in developed countries. METHODS We provide a narrative review of invasive aspergillosis (IA) in liver transplant (LT) recipients. We searched PubMed and Google Scholar for references without language and time restrictions. RESULTS The incidence of IA in LT recipients is low (1.8%), while mortality is high (∼50%). It occurs mainly early (<3 months) after LT. Some risk factors have been identified before (corticosteroid, renal, and liver failure), during (massive transfusion and duration of surgical procedure), and after transplantation (intensive care unit stay, re-transplantation, re-operation). Diagnosis can be difficult and therefore requires full radiological and clinicobiological collaboration. Accurate identification of Aspergillus species is recommended due to the cryptic species, and susceptibility testing is crucial given the increasing resistance of Aspergillus fumigatus to azoles. It is recommended to reduce the dose of tacrolimus (50%) and to closely monitor the trough level when introducing voriconazole, isavuconazole, and posaconazole. Surgery should be discussed on a case-by-case basis. Antifungal prophylaxis is recommended in high-risk patients. Environmental preventative measures should be implemented to prevent outbreaks of nosocomial aspergillosis in LT recipient units. CONCLUSION IA remains a very serious disease in LT patients and should be promptly sought and, if possible, prevented by clinicians when risk factors are identified.

Invasive pulmonary aspergillosis after liver transplantation: lessons from successfully treated cases and review of the literature. Surg Today 2021; 51:1361-1370. [PMID: 33738584 DOI: 10.1007/s00595-021-02263-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Accepted: 12/26/2020] [Indexed: 12/17/2022]
Abstract
PURPOSE Invasive pulmonary aspergillosis (IPA) after liver transplantation (LT) is most often fatal. We analyzed the outcomes of IPA in a single center. METHODS We reviewed, retrospectively, the medical records of recipients of living donor LT (LDLT) or deceased donor LT (DDLT) performed between 1995 and 2019 at our institute. We analyzed the incidence of IPA and assessed the treatment courses of patients treated successfully and those not treatment successfully. RESULTS Among 326 recipients, IPA was diagnosed in 6 (1.8%). The incidence of IPA was significantly higher in patients with acute liver failure (ALF, 9.8%) than in those without ALF (0.4%), after DDLT (8.8%) than after LDLT (1.0%), and in recipients who received preoperative steroid pulse therapy (16.0%) than in those who did not (0.7%). Complete cure of IPA was achieved in the most recent three patients, by administering voriconazole immediately after the diagnosis of IPA and performing lung resection, while the IPA lesion was single and localized. CONCLUSIONS Patients with risk factors for IPA must be monitored closely. Our three successfully treated cases demonstrate that initiating immediate voriconazole treatment and making a calculated decision about lung resection can contribute to a favorable outcome.

Targeted caspofungin prophylaxis for invasive aspergillosis in high-risk liver transplant recipients, a single-center experience. Transpl Infect Dis 2021; 23:e13568. [PMID: 33450126 DOI: 10.1111/tid.13568] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 11/04/2020] [Accepted: 01/03/2021] [Indexed: 01/18/2023]
Abstract
BACKGROUND Invasive aspergillosis (IA) is a rare but highly lethal complication after orthotopic liver transplantation (OLT). Targeted antifungal prophylaxis has been proposed as a strategy to prevent IA among orthotopic liver transplant recipient (OLTr), but limited data are available to support its efficacy. METHOD We conducted a single-center, retrospective, before and after cohort study, comparing IA incidences among OLTr who did not receive antifungal prophylaxis after transplantation (cohort 1) to OLTr who received targeted antifungal prophylaxis after liver transplantation (cohort 2). Patients in cohort 2 received caspofungin prophylaxis if they presented one of the following risk factors: retransplantation, acute liver failure, dialysis, or Aspergillus colonization prior to transplantation. The primary outcome was IA at 90 days after transplantation. RESULTS A total of 391 OLTr were included in the study; 181 patients in the cohort 1 (no prophylaxis) and 210 patients in the cohort 2 (targeted prophylaxis). Among patients in cohort 2, 19% (40/ 210) were considered at high risk for IA and 85% (34/40) of those received caspofungin prophylaxis. The incidence of IA at 90 days was 3.3% (6/ 181) and 0.5% (1/ 210), in cohort 1 and 2, respectively (OR 0.14; 95%CI 0.01-0.83; P = .03). Ninety-day mortality was similar among the two cohorts (3.9% (7/181) and 2.4% (5/210) in cohort 1 and 2, respectively (OR 0.61; 95% 0.18-1.93; P = .40)). The 90-day mortality among the OLTs with IA was 71% (5/7). CONCLUSION Targeted caspofungin prophylaxis was associated with lower rate of IA.

Abstract
These updated AST-IDCOP guidelines provide information on epidemiology, diagnosis, and management of Aspergillus after organ transplantation. Aspergillus is the most common invasive mold infection in solid-organ transplant (SOT) recipients, and it is the most common invasive fungal infection among lung transplant recipients. Time from transplant to diagnosis of invasive aspergillosis (IA) is variable, but most cases present within the first year post-transplant, with shortest time to onset among liver and heart transplant recipients. The overall 12-week mortality of IA in SOT exceeds 20%; prognosis is worse among those with central nervous system involvement or disseminated disease. Bronchoalveolar lavage galactomannan is preferred for the diagnosis of IA in lung and non-lung transplant recipients, in combination with other diagnostic modalities (eg, chest CT scan, culture). Voriconazole remains the drug of choice to treat IA, with isavuconazole and lipid formulations of amphotericin B regarded as alternative agents. The role of combination antifungals for primary therapy of IA remains controversial. Either universal prophylaxis or preemptive therapy is recommended in lung transplant recipients, whereas targeted prophylaxis is favored in liver and heart transplant recipients. In these guidelines, we also discuss newer antifungals and diagnostic tests, antifungal susceptibility testing, and special patient populations.

Caspofungin versus fluconazole as prophylaxis of invasive fungal infection in high-risk liver transplantation recipients: A propensity score analysis. Liver Transpl 2016; 22:427-35.

Abstract
Targeted prophylaxis has proven to be an efficient strategy in liver transplantation recipients (LTRs). The aim of this study was to compare the effectiveness and safety of caspofungin with that of fluconazole in high-risk (HR) LTRs. Caspofungin and fluconazole were compared in a multicenter, retrospective, cohort study in HR-LTRs in Spain. Outcomes were assessed at 180 days after transplantation. A propensity score approach was applied. During the study period (2005-2012), we analyzed 195 HR-LTRs from 9 hospitals. By type of prophylaxis, 97 patients received caspofungin and 98 received fluconazole. Of a total of 17 (8.7%) global invasive fungal infections (IFIs), breakthrough IFIs accounted for 11 (5.6%) and invasive aspergillosis (IA) accounted for 6 (3.1%). By univariate analysis, no differences were observed in the prevention of global IFIs. However, caspofungin was associated with a significant reduction in the rate of breakthrough IFIs (2.1% versus 9.2%, P = 0.04). In patients requiring dialysis (n = 62), caspofungin significantly reduced the frequency of breakthrough IFIs (P = 0.03). The propensity score analysis confirmed a significant reduction in the frequency of IA in patients receiving caspofungin (absolute risk reduction, 0.06; 95% confidence interval [CI], 0.001-0.11; P = 0.044). Linear regression analysis revealed a significant decrease in blood alanine aminotransferase levels and a significant increase in bilirubin levels after administration of caspofungin. Caspofungin and fluconazole have similar efficacy for the prevention of global IFIs in HR-LTRs in this observational, multicenter cohort study. However, caspofungin was associated with a significant reduction of breakthrough IFIs and, after adjusting for confounders, caspofungin was associated with a lower rate of IA. This benefit is probably more favorable in patients on dialysis. Caspofungin is safe in HR-LTRs, although bilirubin levels may be increased.

Abstract
Aspergillus infection remains a significant and deadly complication after liver transplantation (LT). We sought to determine whether the antifungal prophylactic use of voriconazole reduces the incidence of invasive aspergillosis (IA) in high-risk LT recipients without prohibitively increasing cost. During the study era (April 2008 to April 2014), 339 deceased donor LTs were performed. Of those patients, 174 high-risk recipients were administered antifungal prophylaxis with voriconazole. The median biological Model for End-Stage Liver Disease score at the time of LT was 33 (range, 18-49) with 56% requiring continuous renal replacement therapy and 50% requiring ventilatory support immediately before transplantation. Diagnosis of IA was stratified as proven, probable, or possible according to previously published definitions. No IA was documented in patients receiving voriconazole prophylaxis. At 90 days after LT, the institutional cost of prophylaxis was $5324 or 5.6% of the predicted cost associated with post-LT aspergillosis. There was no documentation of resistant strains isolated from any recipient who received voriconazole. In conclusion, these data suggest that voriconazole prophylaxis is safe, clinically effective, and cost-effective in high-risk LT recipients.

Prophylactic use of liposomal amphotericin B in preventing fungal infections early after liver transplantation: a retrospective, single-center study. Transplant Proc 2015; 46:3554-9.

Abstract
In this study the authors evaluated the efficacy of prophylaxis with liposomal amphotericin B (L-AmB) in the incidence of fungal infections (FI) during the first 3 months after liver transplant (LT). The study was retrospective and accessed a 4-year period from 2008 to 2011. All patients who died in the first 48 hours after LT were excluded. Patients were divided by the risk groups for FI: Group 1, high-risk (at least 1 of the following conditions: urgent LT; serum creatinine >2 mg/dL; early acute kidney injury [AKI] after LT; retransplantation; surgical exploration early post-LT; transfused cellular blood components [>40 U]); and Group 2, low-risk patients. Group 1 patients were further separated into those who received antifungal prophylaxis with L-AmB and those who did not. Prophylaxis with L-AmB consisted of intravenous administration of L-AmB, 100 mg daily for 14 days. Four hundred ninety-two patients underwent LT; 31 died in the first 48 hours after LT. From the remaining 461 patients, 104 presented with high-risk factors for FI (Group 1); of these, 66 patients received antifungal prophylaxis and 38 did not. In this group 8 FI were observed, 5 in patients without antifungal prophylaxis (P = .011). Three more FI were identified in Group 2. By logistic regression analysis, the categorical variable high-risk group was independently related to the occurrence of invasive FI (P = .006). We conclude that prophylaxis with L-AmB after LT was effective in reducing the incidence of FI. No influence on mortality was detected.

Abstract
Invasive fungal infections (IFIs) are a common complication in liver transplant recipients. There are no previous randomized trials of an echinocandin for the prevention of IFIs in solid organ transplant recipients. In a randomized, double-blind trial conducted at University-affiliated transplant centers, 200 high-risk liver transplant recipients (100 patients per group) received either anidulafungin or fluconazole for antifungal prophylaxis. Randomization was stratified by Model for End-Stage Liver Disease score ≥30 and receipt of a pretransplant antifungal agent. The primary end point was IFI in a modified intent-to-treat analysis. The overall incidence of IFI was similar for the anidulafungin (5.1%) and the fluconazole groups (8.0%) (OR 0.61, 95% CI 0.19-1.94, p = 0.40). However, anidulafungin prophylaxis was associated with less Aspergillus colonization or infection (3% vs. 9%, p = 0.08), lower breakthrough IFIs among patients who had received pretransplant fluconazole (0% vs. 27%, p = 0.07), and fewer cases of antifungal resistance (no cases vs. 5 cases). Both drugs were well-tolerated. Graft rejection, fungal-free survival, and mortality were similar for both groups. Thus, anidulafungin and fluconazole have similar efficacy for antifungal prophylaxis in most liver transplant recipients. Anidulafungin may be beneficial if the patient has an increased risk for Aspergillus infection or received fluconazole before transplantation.

Abstract
Surgical site infections (SSIs) after liver transplantation (LT) are associated with an increased risk of graft loss and death. The incidence of SSIs after LT and their risk factors have been determined for first LT but not for second LT. The importance of reporting the incidence of SSIs risk-stratified by first LT versus second LT is not known. All patients undergoing second LT at a single institution between 2003 and 2011 (n = 152) were reviewed. The Kaplan-Meier method was used to estimate the cumulative SSI incidence. Relative risks (RRs) and 95% confidence intervals (CIs) from Cox proportional hazards regression models were used to evaluate associations of potential risk factors with SSIs after second LT. Thirty-one patients developed SSIs (6 superficial SSIs, 1 deep SSI, and 24 organ/space SSIs). The cumulative incidence of SSIs 30 days after LT was 20.8% (95% CI = 14%-27%), which was slightly but not significantly higher than the previously reported incidence of SSIs after first LT at our institution between 2003 and 2008 (16%, RR = 1.32, 95% CI = 0.90-1.93, P = .16). Units of transfused red blood cells [RR (doubling) = 1.38, 95% CI = 1.02-1.86, P = .04] and hepaticojejunostomy (RR = 2.22, 95% CI = 1.05-4.72, P = .04) were the only factors associated with SSIs after second LT in single-variable analysis. The associations weakened in a multivariate analysis (P = .07 and P = .07, respectively), potentially because of the correlation of red blood cell transfusions and hepaticojejunostomy (P = .08). In conclusion, the incidence of SSIs after second LT was slightly higher but not significantly different than the published incidence of SSIs (16%) after first LT at the same institution. Significant independent risk factors for SSIs after second LT were not identified. Risk stratification for retransplantation may not be necessary when the incidence of SSIs after LT is being reported.

Abstract
BACKGROUND Limited data exist regarding echinocandins as antifungal prophylaxis in liver transplant recipients. METHODS The efficacy and safety of targeted prophylaxis with micafungin or amphotericin B lipid complex (ABLC) was assessed in a sequential cohort of high-risk patients (posttransplantation dialysis, retransplantation, or reoperation) and compared with those without high risk who did not receive prophylaxis. Outcomes were assessed at 90 days. RESULTS Micafungin versus ABLC recipients were older (P=0.0065) and more likely to have hepatocellular carcinoma (P=0.025). High-risks, that is, dialysis (55.6% vs. 79.2%), retransplantation (5.6% vs. 12.5%), and reoperation (38.9% vs. 20.8%) did not differ between the two groups. Invasive fungal infections developed in 11.1% (2 of 18) of micafungin recipients, 8.3% (2 of 24) of ABLC recipients, and 3% (7 of 234) of patients without high risks (P=0.12). In nondialyzed patients, ABLC versus micafungin recipients had significantly higher serum creatinine on day 14 (P=0.04). However, renal and hepatic function, rejection, graft loss, and mortality did not differ for the two groups on day 90. CONCLUSIONS Targeted prophylaxis with micafungin or ABLC decreased the risk of mycoses in high-risk recipients compared with that in low-risk recipients. Compared with ABLC, however, micafungin appeared to be associated with lower early-renal dysfunction and no additional risk of hepatic dysfunction.

Abstract
Antifungal prophylaxis is recommended in high-risk patients, but risk criteria remain unclear and the predictive value of Model of End-Stage Liver Disease (MELD) score is unknown. In a retrospective, single-center analysis of 667 liver transplants, potential risk factors for fungal infection were assessed, including MELD score. Antifungal prophylaxis was administered in 198 patients (29.4%). During follow-up (mean 43.6 ± 29.6 months), 263 patients (39.4%) developed ≥ 1 episode of fungal infection, and 187 (28.0%) patients developed a probable or proven invasive fungal infection requiring systemic antifungal treatment. Patients receiving antifungal prophylaxis had a lower incidence of fungal infection (29.8% vs. 43.5% without prophylaxis, p < 0.001) and invasive fungal infection (17.7% vs. 32.4%, p < 0.001). One-yr patient survival was 91%, 85% and 69%, respectively, in patients with no fungal infection, fungal colonization and treated invasive fungal infection (p < 0.001); graft survival was 88%, 85% and 66% (p < 0.001). Multivariate analysis indicated that MELD score of 20-30 or ≥ 30 was associated with a 2.0-fold or 4.3-fold increase in relative risk of fungal infection, respectively, and a 2.1-fold or 3.1-fold increase in relative risk of invasive fungal infection. In conclusion, liver transplant patients with a MELD score ≥ 20, and particularly patients with a score ≥ 30, are candidates for antifungal prophylaxis.

Abstract
The high morbidity, mortality, and health care costs associated with invasive fungal infections, especially in the critical care setting and immunocompromised host, have made it an excellent target for prophylactic, empiric, and preemptive therapy interventions principally based on early identification of risk factors. Early diagnosis and treatment are associated with a better prognosis. In the last years there have been important developments in antifungal pharmacotherapy. An approach to the new diagnosis tools in the clinical mycology laboratory and an analysis of the use new antifungal agents and its application in different clinical situations has been made. Furthermore, an attempt of developing a state of the art in each clinical scenario (critically ill, hematological, and solid organ transplant patients) has been performed, trying to choose the best strategy for each clinical situation (prophylaxis, pre-emptive, empirical, or targeted therapy). The high mortality rates in these settings make mandatory the application of early de-escalation therapy in critically ill patients with fungal infection. In addition, the possibility of antifungal combination therapy might be considered in solid organ transplant and hematological patients.

Abstract
Systemic fungal infections remain a significant cause of mortality in neutropenic and immunocompromised patients, despite advances in their diagnosis and treatment. The incidence of such infections is rising due to the use of intensive chemotherapy regimens in patients with solid tumours or haematological cancers, the increasing numbers of allogeneic haematopoietic stem cell and solid organ transplants, and the use of potent immunosuppressive therapy in patients with autoimmune disorders. In addition, the epidemiology of systemic fungal infections is changing, with atypical species such as Aspergillus terreus and zygomycetes becoming more common. Treatment has traditionally focused on empirical therapy, but targeted pre-emptive therapy in high-risk patients and prophylactic antifungal treatment are increasingly being adopted. New treatments, including lipid formulations of amphotericin B, second-generation broad-spectrum azoles, and echinocandins, offer effective antifungal activity with improved tolerability compared with older agents; the potential impact of these treatments is reflected in their inclusion in current treatment and prophylaxis guidelines. New treatment strategies, such as aerosolized lipid formulations of amphotericin B, may also reduce the burden of mortality associated with systemic fungal infections. The challenge is to identify ways of coupling potentially effective treatments with early and reliable identification of patients at highest risk of infection.

Abstract
Although the overall incidence of fungal infections in liver transplant recipients has declined, these infections still contribute significantly to the morbidity and mortality of patients with risk factors for infection. Although antifungal prophylaxis has been widely studied and practiced, no consensus exists on which patients should receive prophylaxis, with which agent, and for what duration. Numerous studies have attempted to ascertain independent risk factors for invasive fungal infections in liver transplant patients, and these data, in addition to clinical trials, identify several patient groups at exceedingly high risk of fungal infection. These include retransplant patients, patients with renal failure requiring hemodialysis or renal replacement therapy, and those requiring reoperations after transplant. Because the majority of infections occur in the first month after transplantation, prophylaxis should be continued for 4-6 weeks. However, local epidemiology and research should guide decisions regarding choice of agent as well as overall development of interinstitutional guidelines, because the incidence and spectrum of infection may differ dramatically among institutions.

Abstract
BACKGROUND Candida krusei (Ck) may cause severe infections in immunocompromised hosts and is innately resistant to fluconazole. PATIENTS AND METHODS During an 18-month period, seven patients with Ck infection were identified at our center. All were treated in the transplant intensive care unit. Candida isolates were grown on Sabouraud agar, and chromosomal DNA was extracted; clonality was investigated using random amplified polymorphic DNA-polymerase chain reaction with primers M13, OPA-18, and OPE-18. RESULTS Among the patients with Ck infection, there were three pancreas recipients with intra-abdominal infection, one liver recipient with cholangitis, one lung recipient with pleural empyema, one patient with pleural empyema after esophageal perforation, and one case of pneumonia in a patient with a ventricular assist device. Treatment consisted of caspofungin (n = 3), voriconazole (n = 1), or a combination of the two (n = 2) together with surgery (n = 3) or pigtail catheter drainage (n = 3). One patient underwent drainage without antifungal treatment, and one patient did not have drainage. The infection was controlled in all cases. The patient with the assist device died from multiple organ dysfunction, the lung recipient died after four months from graft failure, and one pancreas graft was lost. Four patients (57%) harbored the same Ck strain. CONCLUSION Solid organ recipients seem to be at particular risk for Ck infections; clonal outbreaks may occur in intensive care units.

Abstract
There is a rapidly growing population of immunocompromised organ transplant recipients. These patients are at risk of a large variety of infections that have significant consequences on mortality, graft dysfunction, and graft loss. The diagnosis and treatment of these infections are facilitated by an understanding of the preoperative, perioperative, and postoperative risk factors; the typical pathogens; and their characteristic time of presentation. On the basis of these factors, we put forth an algorithm for diagnosing and treating suspected infections in solid organ transplant recipients.

Abstract
We sought to determine the approach to antifungal prophylaxis, and diagnostic and therapeutic practices for the management of invasive aspergillosis in liver transplant recipients. Data were collected by an electronic survey questionnaire sent to all active liver transplant programs in North America; 63% (67/106) of the sites completed the survey. Overall, 91% of the sites employed antifungal prophylaxis; 28% used universal prophylaxis and 72% targeted it toward high-risk patients. Fluconazole was the most commonly used agent for universal and targeted prophylaxis. The leading choice for mold-active agents for antifungal prophylaxis was the echinocandins. Combination therapy was used as primary therapy for invasive aspergillosis in 47%, and as salvage in 80%. Thus, a vast majority of the surveyed programs employ antifungal prophylaxis and most use targeted prophylaxis. Consideration of these practices could guide clinical trial design to optimize antifungal prophylaxis in these patients. Our findings also merit investigations to better define the role of diagnostic assays and combination therapeutic strategies for invasive aspergillosis in liver transplant recipients.

Abstract
Clostridium difficile colitis (CDC) remains a serious and common complication after liver transplantation (LT). Four hundred and sixty-seven consecutive LTs in 402 individuals were performed between 1998 and 2001 at our center. Standard immunosuppression consisted of tacrolimus, mycophenolate, and steroids. CD toxins A and B were detected by using a rapid immunoassay or enzyme immunoassay. CDC was diagnosed in 32 patients (5-1999 days post-LT), with 93.8% (30/32) of patients developing CDC during the first year post-LT; three individuals had CDC more than 3 years post-LT, one of which also had early CDC. All patients presented with abdominal pain and watery diarrhea. Patients who developed CDC within 1-year post-LT were significantly more likely to have a hemorrhagic, biliary, or infectious complication. Patients who developed CDC within 28 days post-LT had a significantly higher model end-stage liver disease score. Treatment consisted of fluid and electrolyte replacement and metronidazole and no patients developed toxic megacolon, required colonic resection, or died from CDC. CDC represents a potentially severe complication following LT. Most cases occur early post-LT. Development of a hemorrhagic, biliary, or infectious complication is associated with the development of CDC.

Abstract
This manuscript will review the risk factors, prevalence, clinical presentation, and management of invasive fungal infections (IFIs) in solid organ transplant (SOT) recipients. Primary literature was obtained via MEDLINE (1966-April 2007) and EMBASE. Abstracts were obtained from scientific meetings or pharmaceutical manufacturers and included in the analysis. All studies and abstracts evaluating IFIs and/or antifungal therapies, with a primary focus on solid organ transplantation, were considered for inclusion. English-language literature was selected for inclusion, but was limited to those consisting of human subjects. Infectious complications following SOT are common. IFIs are associated with high morbidity and mortality rates in this patient population. Determining the best course of therapy is difficult due to the limited availability of data in SOT recipients. Well-designed clinical studies are infrequent and much of the available information is often based on case-reports or retrospective analyses. Transplant practitioners must remain aware of their therapeutic options and the advantages and disadvantages associated with the available treatment alternatives.

Abstract
Invasive aspergillosis (IA) is a severe complication of liver transplantation. Risk factors for IA after deceased donor liver transplantation (DDLT) have been presented in several reports, but are not well established for living donor liver transplant recipients. Here, a retrospective case-control study was performed. Five cases with IA were investigated after living donor liver transplantation (LDLT) between January 1999 and December 2002 at Kyoto University Hospital. For comparison, living donor liver transplant recipients without IA were taken as controls. These patients had undergone LDLT 1 month before or after each IA case and had the same survival times as the latter. We evaluated the clinical and laboratory findings for both groups up until their demise. Patients with IA after LDLT had a very poor prognosis. By univariate analysis, risk factors for IA were preoperative intensive care unit stay (P = 0.02) and preoperative steroid administration (P = 0.02). Preoperative steroid administration for fulminant hepatitis possibly predisposed to the development of IA after LDLT.

Abstract
PURPOSE OF REVIEW New broader spectrum antifungal agents with favorable safety profiles have been available for the last 15 years making prophylaxis feasible. The purpose of this article is to review recent studies in patient populations at high risk for invasive fungal infections. RECENT FINDINGS Itraconazole, lipid formulations of amphotericin B, posaconazole, caspofungin and micafungin have been utilized for prophylaxis in different immunocompromised host settings. Itraconazole and caspofungin remain an option especially in patients with hematological diseases. Low dose liposomal amphotericin B shows a lower morbidity rate in patients treated for acute myeloid leukemia. Posaconazole demonstrated survival benefits in this setting although data have only been presented at an international meeting. In the transplantation setting, micafungin was superior to fluconazole during the early neutropenic phase and posaconazole was superior to fluconazole in preventing invasive aspergillosis in hematopoietic transplant recipients treated for graft-versus-host disease. Results from the latter study have thus far only been presented in abstract form. SUMMARY Prophylaxis should only be given to a high-risk population. Results of studies should demonstrate morbidity and mortality advantages. The new generation of azoles and echinocandins have a favorable safety and drug interaction profile and appear advantageous in specific settings of immunosuppression. Pending full publication, posaconazole appears to be an appropriate agent for prophylaxis in acute myeloid leukemia patients or patients treated for graft-versus-host disease. Micafungin is superior to fluconazole in the neutropenic phase of hematopoietic transplantation.

Abstract
Invasive fungal infection is a serious complication of orthotopic liver transplantation, but its risk factors remain incompletely defined. Iron overload has already been associated with increased risk of fungal infections, but it has not yet been assessed as a risk factor in liver transplantation. We retrospectively studied a cohort of 153 consecutive patients who underwent their first liver transplantation at a single center and who survived at least 7 days after transplantation. The association between various pretransplant patient characteristics, including hepatic explant iron and risk of invasive fungal infections, was analyzed by univariate and multivariate models. Iron in the hepatic explant was assessed by Perl's Prussian blue stain by a pathologist blinded to clinical outcome. During the first year after transplantation, 28 of 153 patients developed a total of 31 invasive fungal infections, of which 21 (68%) were caused by Candida, 7 (23%) by Aspergillus, 2 (6%) by Cryptococcus, and 1 (3%) by Saccharomyces. Stainable iron in the hepatic explant was found in 48 patients (31%). Stainable iron in the hepatic explant was found to be strongly and independently associated with posttransplantation fungal infections in multivariate analysis (hazard ratio 3.09; 95% confidence interval 1.45-6.56; P = 0.003). Hepatic iron overload is strongly and independently associated with posttransplantation invasive fungal infections. Studies to confirm this finding in other centers and define the mechanism are warranted.

Abstract
Peritonitis occurring after liver transplantation (PLT) has been poorly characterized to date. The aims of this study were to define the incidence, risk factors, microbiology profiles, and outcome of nonlocalized PLT. This was a retrospective study of 950 cadaveric liver transplantation (LT) procedures in 837 patients, followed for a mean of 1,086 days (range, 104-2,483 days) after LT. PLT was defined as the presence of at least one positive ascitic fluid culture after LT. There were 108 PLT episodes in 91 patients occurring at a median of 14 days (range, 1-102 days) after LT. Significant risk factors associated with the development of PLT by multivariate analysis included pre-LT model for end-stage liver disease score, duration of LT surgery, Roux-en-Y biliary anastomosis, and renal replacement therapy after LT. Biliary complications, intra-abdominal bleeding, and bowel leak/perforation were associated with 34.3%, 26.9%, and 18.5% of episodes, respectively. Multiple organisms, gram-positive cocci, fungus, and multidrug-resistant bacteria were isolated in 61.1%, 92.6%, 25.9%, and 76.9% of ascitic fluid cultures, respectively. The 28 fungal PLT episodes were associated with bowel leak/perforation and polymicrobial peritonitis. Patients who developed PLT after their first LT had a significantly greater risk of graft loss or mortality compared to unaffected patients. Parameters significantly associated with these adverse outcomes by multivariate analysis were recipient age at LT and bowel leak or perforation after LT. In conclusion, PLT is a serious infectious complication of LT, associated with significant intra-abdominal pathology and reduced recipient and graft survival.

Abstract
Retransplantation is a major risk factor for invasive aspergillosis in liver transplant recipients. However, the risk for invasive aspergillosis with time elapsed since retransplantation, clinical characteristics, and outcome of patients who develop this infection after retransplantation of the liver has not been defined. Patients comprised 17 liver retransplant recipients with invasive aspergillosis between 1990 and 2004. Retransplantation was considered early if it was performed within 30 days and late if performed after 30 days of the first or primary transplant. Retransplant recipients comprised 25% of all cases of invasive aspergillosis after liver transplantation. Fifty-three percent of the Aspergillus infections occurred within 30 days, and 76% within 90 days of retransplantation. In all, 53% (9/17) of the patients were late retransplant recipients. Late compared to early retransplant recipients with invasive aspergillosis were more likely to have central nervous system involvement with invasive aspergillosis (56% vs. 0%, P = 0.03). Mortality rate was 100% for late and 63% for early retransplant recipients with Aspergillus infections. In conclusion, time-varying risk for invasive aspergillosis after retransplantation has implications relevant for guiding antifungal prophylaxis. Given a greater risk for disseminated infection and poor outcome in late retransplant recipients with aspergillosis, potent and aggressive antifungal therapy should be considered upfront in these patients.
