Abstract
Background and aim The global burden of invasive fungal infections (IFIs) is emerging in immunologic deficiency status from various disease. Patients with acute-on-chronic hepatitis B liver failure (ACHBLF) are prone to IFI and their conditions are commonly exacerbated by IFI. However, little is known about the characteristics and risk factors for IFI in hospitalized ACHBLF patients. Methods A total of 243 hospitalized ACHBLF patients were retrospectively enrolled from January 2010 to July 2023. We performed restricted cubic spline analysis to determine the non-linear associations between independent variables and IFI. The risk factors for IFI were identified using logistic regression and the extreme gradient boosting (XGBoost) algorithm. The effect values of the risk factors were determined by the SHapley Additive exPlanations (SHAP) method. Results There were 24 ACHBLF patients (9.84%) who developed IFI on average 17.5 (13.50, 23.00) days after admission. The serum creatinine level showed a non-linear association with the possibility of IFI. Multiple logistic regression revealed that length of hospitalization (OR = 1.05, 95% CI: 1.02-1.08, P = 0.002) and neutrophilic granulocyte percentage (OR = 1.04, 95% CI: 1.00-1.09, P = 0.042) were independent risk factors for IFI. The XGBoost algorithm showed that the use of antibiotics (SHAP value = 0.446), length of hospitalization (SHAP value = 0.406) and log (qHBV DNA) (SHAP value = 0.206) were the top three independent risk factors for IFI. Furthermore, interaction analysis revealed no multiplicative effects between the use of antibiotics and the use of glucocorticoids (P = 0.990). Conclusion IFI is a rare complication that leads to high mortality in hospitalized ACHBLF patients, and a high neutrophilic granulocyte percentage and length of hospitalization are independent risk factors for the occurrence of IFI.

Invasive Fungal Breakthrough Infections under Targeted Echinocandin Prophylaxis in High-Risk Liver Transplant Recipients. J Fungi (Basel) 2023; 9:jof9020272. [PMID: 36836384 PMCID: PMC9961099 DOI: 10.3390/jof9020272] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 02/15/2023] [Accepted: 02/17/2023] [Indexed: 02/22/2023] Open
Abstract
Invasive fungal infections (IFIs) are frequent and outcome-relevant complications in the early postoperative period after orthotopic liver transplantation (OLT). Recent guidelines recommend targeted antimycotic prophylaxis (TAP) for high-risk liver transplant recipients (HR-LTRs). However, the choice of antimycotic agent is still a subject of discussion. Echinocandins are increasingly being used due to their advantageous safety profile and the increasing number of non-albicans Candida infections. However, the evidence justifying their use remains rather sparse. Recently published data on breakthrough IFI (b-IFI) raise concerns about echinocandin efficacy, especially in the case of intra-abdominal candidiasis (IAC), which is the most common infection site after OLT. In this retrospective study, we analyzed 100 adult HR-LTRs undergoing first-time OLT and receiving echinocandin prophylaxis between 2017 and 2020 in a tertiary university hospital. We found a breakthrough incidence of 16%, having a significant impact on postoperative complications, graft survival, and mortality. The reasons for this may be multifactorial. Among the pathogen-related factors, we identified the breakthrough of Candida parapsilosis in 11% of patients and one case of persistent IFI due to the development of a secondary echinocandin resistance of an IAC caused by Candida glabrata. Consequently, the efficacy of echinocandin prophylaxis in liver transplantation should be questioned. Further studies are necessary to clarify the matter of breakthrough infections under echinocandin prophylaxis.

Abstract
BACKGROUND Aspergillosis is a frequent invasive fungal infection in liver recipients (affecting 1%-9.2% of all patients), second only to candidiasis. Significant risk factors for invasive aspergillosis in liver recipients include corticosteroid therapy, neutropenia, T-cell dysfunction, renal failure and requirement for renal replacement therapy. Aspergillus infection usually affects the lungs of liver recipients, with hematogenous dissemination occurring in 50%-60% of cases. Renal involvement is rare and is considered to occur in 0.4% of all cases of invasive aspergillosis.
CASE SUMMARY This paper describes a case of a liver recipient presenting with a newly formed renal mass a year after liver transplantation. The patient underwent liver transplantation due to alcoholic liver cirrhosis, with preoperative corticosteroid therapy and postoperative immunosuppressants (tacrolimus and mycophenolate mofetil). His 1-year follow-up was uneventful, with a satisfying graft function and lack of any symptoms. During a routine follow-up abdominal ultrasound, he was diagnosed with a renal tumor. The renal imaging findings were inconclusive (with a differential diagnosis to renal cell carcinoma), while the computed tomography (CT) of the chest showed scar tissue in the lungs suggestive of previous inflammation. The patient underwent radical nephrectomy, with histopathological analysis showing renal aspergilloma, yielding postoperative treatment with voriconazole. His follow up was uneventful, and the chest CT did not show any change in pulmonary lesions. This case illustrates the possibility of aspergillosis affecting the lungs of liver recipients, subsequently affecting the kidney and forming an aspergilloma.
CONCLUSION Clinicians should be aware of aspergilloma mimicking solid organ tumors in organ recipients.

Abstract
Invasive fungal infections (IFIs) postliver transplantation are a frequent cause of morbidity and mortality; however, studies reporting on these infections in the paediatric population are scarce. To investigate the incidence and risk factors of IFIs in paediatric liver transplant recipients during the early posttransplantation period (≤3 months). Data were collected for all paediatric liver transplant recipients registered in a national transplantation center from 2004 to 2014. Using a stepwise logistic regression to identify independent risk factors for IFIs, a predictive model was formulated. Ten IFIs were identified in 81 liver transplant recipients (12.3%) all occurring during the first month posttransplantation. Candida species were responsible for nine cases (90%), of which four were non-albicans Candida (44%). Significant risk factors were identified; recipient of multiple blood product transfusions during transplantation, prolonged use of indwelling intravenous catheter, prolonged IV antibiotic treatment, surgical complications, pulse steroid treatment and living donor liver transplantation. The predictive model used two clinical parameters to define high-risk patients: a living donor transplantation and duration of IV antibiotic treatment (area under the ROC curve 0.918). IFIs are a significant complication occurring in the first month posttransplantation. Future studies are required to assess efficacy of targeted antifungal prophylaxis in high risk patients.

Abstract
Candida species remains one of the most important causes of opportunistic infections worldwide. Invasive candidiasis (IC) is associated with considerable morbidity and mortality in liver disease (LD) patients if not treated promptly. Echinocandins are often recommended as a first-line empirical treatment for managing IC and can especially play a critical role in managing IC in LD patients. However, advanced LD patients are often immunocompromised and critically ill. Hence altered pharmacokinetics, drug interactions as well as tolerance issues of antifungal treatments are a concern in these patients. This comprehensive review examines the epidemiology, risk factors and diagnosis of IC in patients with LD and evaluates differences between three available echinocandins for treating this group of patients.

Abstract
Infections are the leading cause of morbidity and mortality in liver transplant (LT) recipients. We studied timeline, spectrum of infection, system involved, and antimicrobial resistance in 64 patients undergoing live donor LT with 6-month follow-up. Of 64 patients, 38 (59.5%) patients had 103 infectious episodes, 10 patients had single infectious episode and 28 patients had two or more infectious episodes. 96 (93.2%) were bacterial and Candida infections were in 7 (6.8%). Early phase had 30 (29.1%) episodes; intermediate phase 25 (24.2%) and late phase 48 (46.6%). Mortality was 11/64 (17.1%). Knowledge of timeline, aetiological agent and antimicrobial resistance is useful to guide empirical therapy and infection prevention.

Abstract
The aim of this study was to investigate the variability of the voriconazole plasma level and its relationships with clinical outcomes and adverse events among liver transplant recipients to optimize the efficacy and safety of their treatment. Liver transplant recipients treated with voriconazole were included, and voriconazole trough levels were quantified by a validated high-performance liquid chromatography method. Cytochrome P450 genotypes for CYP2C19 were evaluated in allograft liver tissues. A total of 832 voriconazole trough levels from 104 patients were measured. Proven, probable, and possible invasive fungal infections were reported for 8/104 (7.7%), 42/104 (40.4%), and 54/104 (51.9%) patients, respectively. Receiver operating characteristic (ROC) curve analysis indicated that trough concentrations of ≥1.3 μg/ml minimized the incidence of treatment failure (95% confidence interval [CI], 0.68 to 0.91 μg/ml) (P < 0.001) and that those of <5.3 μg/ml minimized the incidence of any adverse events (95% CI, 0.83 to 0.97 μg/ml) (P < 0.001). Voriconazole trough levels were significantly higher for heterozygous extensive metabolizers, poor metabolizers, and individuals receiving coadministration with proton pump inhibitors. For ultrarapid metabolizers, oral administration of voriconazole, and concomitant use of glucocorticoids, voriconazole blood concentrations were significantly reduced. Furthermore, there was no statistically significant association of patient age, weight, or gender or coadministration of tacrolimus and cyclosporine with the voriconazole trough level. In conclusion, the results of our analysis indicate large inter- and intraindividual variabilities of voriconazole concentrations in liver transplant recipients. Voriconazole trough concentrations of ≥1.3 μg/ml and <5.3 μg/ml are optimal for treatment and for minimization of adverse events. Optimization of drug efficacy and safety requires the use of rational doses for voriconazole therapy.

Abstract
In solid organ transplant (SOT) recipients, invasive fungal infections (IFIs) are associated with significant morbidity and mortality. Detection of IFIs can be difficult because the signs and symptoms are similar to those of viral or bacterial infections, and diagnostic techniques have limited sensitivity and specificity. Clinicians must rely on knowledge of the patient's risk factors for fungal infection to make a diagnosis. The authors describe their approach to the SOT recipient with suspected fungal infection. The epidemiology of IFIs in the SOT population is reviewed, and a syndromic approach to suspected IFI in SOT recipients is described.

Abstract
Fungal invasive infections are rare in general population but are an emergent cause of infection in the immunocompromized population, especially in the solid organ transplant recipients. Herein the authors report a clinical case of a liver transplanted patient suffering a cutaneous co-existent infection with A. alternata as well as A. infectoria. To our knowledge this is the first case of cutaneous concomitant infection due to those two species reported not only in Portugal but also worldwide. The patient was treated with surgical excision of the lesions and oral itraconazol without relapse.

Abstract
In this randomized clinical trial comparing micafungin 100 mg with standard-care antifungal prophylaxis (fluconazole, liposomal amphotericin B, or caspofungin) in high-risk liver transplant patients, micafungin 100 mg was noninferior and had a better kidney safety profile. Background. Invasive fungal infection (IFI) following liver transplant is associated with significant morbidity and mortality. Antifungal prophylaxis is rational for liver transplant patients at high IFI risk. Methods. In this open-label, noninferiority study, patients were randomized 1:1 to receive intravenous micafungin 100 mg or center-specific standard care (fluconazole, liposomal amphotericin B, or caspofungin) posttransplant. The primary endpoint was clinical success (absence of a proven/probable IFI and no need for additional antifungals) at end of prophylaxis (EOP). Noninferiority (10% margin) of micafungin vs standard care was assessed in the per protocol and full analysis sets. Safety assessments included adverse events and liver and kidney function tests. Results. The full analysis set comprised 344 patients (172 micafungin; 172 standard care). Mean age was 51.2 years; 48.0% had a Model for End-Stage Liver Disease score ≥20. At EOP (mean treatment duration, 17 days), clinical success was 98.6% for micafungin and 99.3% for standard care (Δ standard care – micafungin [95% confidence interval], 0.7% [−2.7% to 4.4%]) in the per protocol set and 96.5% and 93.6%, respectively (−2.9% [−8.0% to 1.9%]), in the full analysis set. Incidences of drug-related adverse events for micafungin and standard care were 11.6% and 16.3%, leading to discontinuation in 6.4% and 11.6% of cases, respectively. At EOP, liver function tests were similar but creatinine clearance was higher in micafungin- vs standard care–treated patients. Conclusions. Micafungin was noninferior to standard care as antifungal prophylaxis in liver transplant patients at high risk for IFI. Adverse event profiles and liver function at EOP were similar, although kidney function was better with micafungin. Clinical Trials Registration. NCT01058174.

Abstract
BACKGROUND Aspergillus infection was mostly reported with high mortality rates and a bad prognosis in immunocompromised patients, but data were lacking on the clinical characteristics of aspergillus infection in liver cirrhosis. The aim of this study was to retrospectively assess the morbidity and mortality rate, clinical manifestation, risk factors, and medication of invasive pulmonary aspergillosis (IPA) in liver cirrhosis in The First Affiliated Hospital, College of Medicine, Zhejiang University. METHODS Patients with liver cirrhosis who had been diagnosed with proven or probable IPA by clinical and laboratory parameters from 1st December 2008 to 1st May2012 were retrospectively evaluated for predisposing factors for IPA and clinical outcome. The follow up ended on 30th July2012. IPA was defined according to European Organization for Research and Treatment of Cancer/Mysoses Study group criteria. RESULTS In total, 6,600 patients with liver cirrhosis were enrolled, and 19 out of these developed IPA. Seventeen out of 19 patients died. Imaging findings such as the halo sign and lower respiratory tract infection symptoms contributed to the early diagnosis of IPA. Possible risk factors for IPA included a high Child-Turcotte-Pugh (CTP) score, broad antibiotic usage and steroid exposure. The use of antifungal compounds may prolong a patient's life. CONCLUSIONS The mortality of liver cirrhosis with IPA is high. Liver cirrhosis should be considered a risk factor of IPA. Once patients with high CTP scores and steroid and broad spectrum antibiotics exposure present cough and fever, IPA should be taken into consideration and antifungal agents should be used as soon as possible.

Abstract
BACKGROUND Invasive pulmonary aspergillosis (IPA) in acute-on-chronic liver failure (ACLF) patients is associated with a high mortality. But the clinical characteristics of and the risk factors for IPA among patients with ACLF remains unclear. This study was aimed at assessing clinical manifestation, the risk factors and antifungal medications for as well as the mortality due to IPA in ACLF patients at the First Affiliated Hospital, College of Medicine, Zhejiang University. PATIENTS AND METHODS Patients with ACLF who were diagnosed with proven or probable IPA by clinical and laboratory parameters from 1 December 2008 to 1 May 2012 were retrospectively evaluated to determine the risk factors for IPA and the clinical outcomes. The follow-up ended on 30 July 2012. Multivariate analysis was performed to identify the risk factors for mortality and the development of IPA. RESULTS In total, 787 patients with ACLF were enrolled, and 39 of these patients developed IPA. Thirty seven of these 39 patients died in spite of treatment with antifungal drugs. Controls included 48 patients who did not have a pulmonary infection. The survival rate of patients with IPA was significantly lower than that of those without IPA. IPA was found to be independently associated with age (p = 0.021), encephalopathy (p = 0.002), and steroid use (p = 0.000). There was significant difference in the prognosis between the patients treated with either voriconazole or itraconazole and those without antifungal treatment. CONCLUSIONS Patients with ACLF and IPA have a high mortality rate. Patients with ACLF who present with encephalopathy should avoid steroids, as they increase the mortality rate. Azoles may prolong the survival time.

[PMID: 22563180 PMCID: PMC3337575 DOI: 10.3748/wjg.v18.i16.1975] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2011] [Revised: 12/02/2011] [Accepted: 03/10/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To identify factors related to serious postoperative bacterial and fungal infections in the first 3 mo after living donor liver transplantation (LDLT).
METHODS: In the present study, the data of 207 patients from 2004 to 2011 were reviewed. The pre-, intra- and post-operative factors were statistically analyzed. All transplantations were approved by the ethics committee of West China Hospital, Sichuan University. Patients with definitely preoperative infections and infections within 48 h after transplantation were excluded from current study. All potential risk factors were analyzed using univariate analyses. Factors significant at a P < 0.10 in the univariate analyses were involved in the multivariate analyses. The diagnostic accuracy of the identified risk factors was evaluated using receiver operating curve.
RESULTS: The serious bacterial and fungal infection rates were 14.01% and 4.35% respectively. Enterococcus faecium was the predominant bacterial pathogen, whereas Candida albicans was the most common fungal pathogen. Lung was the most common infection site for both bacterial and fungal infections. Recipient age older than 45 years, preoperative hyponatremia, intensive care unit stay longer than 9 d, postoperative bile leak and severe hyperglycemia were independent risk factors for postoperative bacterial infection. Massive red blood cells transfusion and postoperative bacterial infection may be related to postoperative fungal infection.
CONCLUSION: Predictive risk factors for bacterial and fungal infections were indentified in current study. Pre-, intra- and post-operative factors can cause postoperative bacterial and fungal infections after LDLT.
