[PMID: 39261262 DOI: 10.1016/j.clinthera.2024.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 08/13/2024] [Accepted: 08/19/2024] [Indexed: 09/13/2024]
Abstract
PURPOSE Infections caused by Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp (ESKAPE) plus Escherichia coli (E2SKAPE), in particular multidrug-resistant (MDR) E2SKAPE infections, occur frequently and pose a life-threatening to liver transplant (LT) recipients. To prevent E2SKAPE infections and improve the prognosis of LT recipients, the identification of risk factors for E2SKAPE infections and mortality is necessary. METHODS E2SKAPE pathogens were isolated and identified from clinical samples following standard microbiological procedures. All episodes of E2SKAPE infections and mortality documented among LT recipients were analyzed. FINDINGS A total of 83 episodes of E2SKAPE infections, including 75 (90.4%) episodes of MDR-E2SKAPE infections, occurred in 23.1% (53/229) of LT recipients. E. faecium was the dominant causative bacterium (37/83; 44.6%). The most common site of infections was the urinary tract (14/53; 26.4%). Sixteen (7%) patients died within 2 months after LT, and 7 deaths were E2SKAPE infections-related. Multivariate logistic regression analysis revealed that female sex [odds ratio (OR) = 3.665, 95% confidence interval (CI): 1.614-8.321, P = 0.002], duration of surgery ≥ 400 min [OR = 2.328, 95%CI: 1.151-4.707, P = 0.019], intraoperative red blood cell (RBC) transfusion ≥ 12U [OR = 2.542, 95%CI: 1.218-5.306, P = 0.013] and indwelling urethral catheter use ≥ 3 days [OR = 3.96, 95%CI: 1.309-11.981, P = 0.015] were independent risk factors for E2SKAPE infections after LT, and that only exposure to more than 2 intravenous antibiotics post-LT [OR = 0.318, 95%CI: 0.15-0.674, P = 0.003] was negatively associated with acquisition of E2SKAPE infections. The predictors of crude mortality included female sex [OR = 4.822, 95%CI: 1.299-17.904, P = 0.019], creatinine on day 3 post-LT > 1.5 mg/dL [OR = 11.014, 95%CI: 2.985-40.637, P < 0.001], mechanical ventilation post-LT [OR = 10.724, 95%CI: 2.695-42.676, P = 0.001] and recipients with E2SKAPE infections [OR = 4.112, 95%CI: 1.169-14.47, P = 0.028]. IMPLICATIONS A high incidence of E2SKAPE infections was noted in the early post-LT period. The most common infection site was the urinary tract, and the dominant pathogenic bacterium was E. faecium. Female sex, prolonged surgery time, massive RBC transfusion, or delayed urethral catheter removal were associated with E2SKAPE infections. Only exposure to more than 2 intravenous antibiotics post-LT was negatively related to the acquisition of E2SKAPE infections. The predictors of mortality included female sex, creatinine on day 3 post-LT>1.5 mg/dL, mechanical ventilation post-LT, and recipients with E2SKAPE infections.

Anouti A, Al Hariri M, VanWagner LB, Lee WM, Mufti A, Pedersen M, Shah J, Hanish S, Vagefi PA, Cotter TG, Patel MS. Early Graft Failure After Living-Donor Liver Transplant. Dig Dis Sci 2024; 69:1488-1495. [PMID: 38381224 DOI: 10.1007/s10620-024-08280-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 01/04/2024] [Indexed: 02/22/2024]
Abstract
BACKGROUND Living-donor liver transplantation (LDLT) has been increasing in the USA. While data exist on longer-term patient and graft outcomes, a contemporary analysis of short-term outcomes is needed. AIM Evaluate short-term (30-day) graft failure rates and identify predictors associated with these outcomes. METHODS Adult (≥ 18) LDLT recipients from 01/2004 to 12/2021 were analyzed from the United States Scientific Registry of Transplant Recipients. Graft status at 30 days was assessed with graft failure defined as retransplantation or death. Comparison of continuous and categorical variables was performed and a multivariable logistic regression was used to identify risk factors of early graft failure. RESULTS During the study period, 4544 LDLTs were performed with a graft failure rate of 3.4% (155) at 30 days. Grafts from male donors (aOR: 0.63, CI 0.44-0.89), right lobe grafts (aOR: 0.40, CI 0.27-0.61), recipients aged > 60 years (aOR: 0.52, CI 0.32-0.86), and higher recipient albumin (aOR: 0.73, CI 0.57-0.93) were associated with superior early graft outcomes, whereas Asian recipient race (vs. White; aOR: 3.75, CI 1.98-7.10) and a history of recipient PVT (aOR: 2.7, CI 1.52-4.78) were associated with inferior outcomes. LDLTs performed during the most recent 2016-2021 period (compared to 2004-2009 and 2010-2015) resulted in significantly superior outcomes (aOR: 0.45, p < 0.001). CONCLUSION Our study demonstrates that while short-term adult LDLT graft failure is uncommon, there are opportunities for optimizing outcomes by prioritizing right lobe donation, improving candidate nutritional status, and careful pre-transplant risk assessment of candidates with known PVT. Notably, a period effect exists whereby increased LDLT experience in the most recent era correlated with improved outcomes.

Ann Epidemiol 2024; 89:21-28. [PMID: 38042439 DOI: 10.1016/j.annepidem.2023.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/24/2023] [Accepted: 11/27/2023] [Indexed: 12/04/2023]
Abstract
BACKGROUND Herpes simplex virus (HSV) is an opportunistic infection antigen in solid organ transplant (SOT) recipients. However, this phenomenon has received limited attention from epidemiologists. Our study aims to determine the HSV infection risk in SOT recipients. METHODS This was a nationwide population-based cross-sectional study based on the National Health Insurance Research Database from 2002 to 2015. We used propensity score matching to avoid selection bias and analyzed the association between HSV infection and SOT recipients with multiple logistic regression analysis. RESULTS At a 3-year follow-up, SOT recipients had a higher risk of developing HSV, with an adjusted odds ratio (aOR) of 3.28 (95% confidence interval (CI), 2.51-4.29). Moreover, at 6-month, 1-year, and 2-year follow-ups, SOT recipients also had an increased risk of HSV than general patients with aORs of 3.85 (95% CI, 2.29-6.49), 4.27 (95% CI, 2.86-6.36), and 3.73 (95% CI, 2.74-5.08), respectively. In the subgroup analysis, lung transplant recipients (aOR = 8.01; 95% CI, 2.39-26.88) exhibited a significantly higher chance of HSV among SOT recipients, followed by kidney transplant recipients (aOR = 3.33; 95% CI, 2.11-5.25) and liver transplant recipients (aOR = 3.15; 95% CI, 2.28-4.34). CONCLUSION HSV can develop at any time after organ transplantation. SOT recipients had a higher risk of HSV infection than the general population at 6 months, 1 year, 2 years, and 3 years after transplantation, with the highest chance at 1 year after. In addition, the patients who underwent lung transplantion were at higher risk for HSV infection than liver or kidney transplant recipients.

Abstract
Introduction and objectives Liver transplantation and its indications represent an increased burden on patients' health. This can be represented in a variety of ways, such as in emergency visits, unscheduled clinic visits, and unanticipated admissions. This study aims to analyze emergency department (ED) visits, the most common presenting complaints, and the outcomes of those visits. Methods A retrospective observational study was performed in which electronic medical records were reviewed for all patients who underwent liver transplantation and presented to the emergency department between October 2011 and October 2021. The following data were collected: demographics, comorbidities, liver transplant features, and emergency department visit data and outcomes. Recurrent visits were assessed and labeled as first, second, third, fourth, and fifth or more. Results A total of 699 patients and 5,225 visits were included in the analysis. Living donors accounted for 80% of all transplants. The mean post-operative length of stay was 22.6 ± 17.8. The majority of patients (74%) had at least one comorbidity, with diabetes (47%), hypertension (31%), and chronic kidney disease (CKD) (16%) being the commonest comorbidities; however, comorbidities were not associated with an increased risk of emergency department visits. Out of the 5,225 visits to the emergency department, 2,265 (41%) were within the first year. Emergency department visits in the first seven days after discharge amounted to 22% of total first visits. By 30 days, six months, and one year, they increased to 46%, 83%, and 91%, respectively. Living donor recipients had an average of 7.3 ED visits as compared to deceased donor recipients, who had an average of 8.4 ED visits. The most common presenting complaints were gastrointestinal (GI) symptoms (18%), infectious disease symptoms (9%), and respiratory symptoms (8%). There were a total of 296 patients who were readmitted at least once since discharge after liver transplantation. Conclusion The majority of first-time presentations to ED occurred in the first year post-transplant, marking this time period as critical for liver transplant patients. Our study also highlighted the continual presentations of liver transplant patients to the ED a few years post-transplant. This requires close scrutiny of the main causes of such presentations as well as comparison with other transplant cases to identify whether they are specific to liver transplants or not.

Abstract
BACKGROUND Using Antimicrobial stewardship programs (ASP) to monitor the use of antibiotics can lead to improved antibiotic use and reduced costs. METHODS This retrospective cohort study was done at Shiraz Organ Transplant Center, the largest transplant center in Asia. Antimicrobial use, cost, clinical outcomes, and antibiotic resistance pattern were evaluated before and after ASP. RESULTS This study included 2791 patients, 1154 of whom were related to the time before ASP and 1637 to the time after ASP. During the period of the research, a total of 4051 interventions were done. The use of all classes of antibiotics was significantly reduced by ASP, with 329 DDD/100PD before the intervention compared to 201 DDD/100PD after it (p = 0.04). In addition, the overall cost of antibiotics purchased was much lower after the ASP measures were implemented ($43.10 per PD) than before implementation of the ASP measures ($60.60 per PD) (p = 0.03). After the implementation of ASP, the number of MDR isolates was significantly reduced. CONCLUSION The results of our study showed that the implementation of ASP significantly reduced the number and costs of antibiotics and also the number of resistant pathogens, but did not affect the patients' length of stay.

A Reduction of Calcineurin Inhibitors May Improve Survival in Patients with De Novo Colorectal Cancer after Liver Transplantation. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58121755. [PMID: 36556957 PMCID: PMC9785597 DOI: 10.3390/medicina58121755] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 11/25/2022] [Accepted: 11/28/2022] [Indexed: 12/04/2022]
Abstract
Background and Objectives: After liver transplantation (LT), long-term immunosuppression (IS) is essential. IS is associated with de novo malignancies, and the incidence of colorectal cancer (CRC) is increased in LT patients. We assessed course of disease in patients with de novo CRC after LT with focus of IS and impact on survival in a retrospective, single-center study. Materials and Methods: All patients diagnosed with CRC after LT between 1988 and 2019 were included. The management of IS regimen following diagnosis and the oncological treatment approach were analyzed: Kaplan−Meier analysis as well as univariate and multivariate analysis were performed. Results: A total of 33 out of 2744 patients were diagnosed with CRC after LT. Two groups were identified: patients with restrictive IS management undergoing dose reduction (RIM group, n = 20) and those with unaltered regimen (maintenance group, n = 13). The groups did not differ in clinical and oncological characteristics. Statistically significant improved survival was found in Kaplan−Meier analysis for patients in the RIM group with 83.46 (8.4−193.1) months in RIM and 24.8 (0.5−298.9) months in the maintenance group (log rank = 0.02) and showed a trend in multivariate cox regression (p = 0.054, HR = 14.3, CI = 0.96−213.67). Conclusions: Immunosuppressive therapy should be reduced further in patients suffering from CRC after LT in an individualized manner to enable optimal oncological therapy and enable improved survival.

Abstract
OBJECTIVES Patients with acute-on-chronic liver failure (ACLF) have a high risk of infection after liver transplantation (LT). In this study, we aimed to evaluate the prevalence of early post-LT infection (within one month after LT) in recipients with ACLF, and to compare the survival rate between patients with or without post-LT infection. METHODS Patients with ACLF who underwent LT between January 2015 and December 2017 were retrospectively included. Characteristics of the patients, prevalence, site and pathogen of post-LT infection, and its risk factors were evaluated. RESULTS A total of 62 patients with ACLF developed bacterial or fungal infection after LT. The 30-day, 90-day, and 1-year survival rates in the infected group were found to be significantly lower than those in the non-infected group (67.7% vs 98.5%, 64.5% vs 97.7%, and 48.4% vs 95.4%; all P < 0.001). The most common pathogens involved were carbapenem-resistant gram-negative organisms, including Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter lwoffi. Multivariate analysis demonstrated that reoperation and length of intensive care unit stay were independently associated with post-LT infection. In addition, living donor LT and early allograft dysfunction were independently associated with 30-day all-cause mortality, whereas red blood cell transfusion and post-LT infection were independently associated with all-cause 30-day and 90-day mortality after LT. CONCLUSIONS Early infection after LT is a major prognostic factor in patients with ACLF. Constant vigilance for the risk factors of early infection after LT is needed for timely diagnosis and prompt intervention.

Abstract
End-stage liver disease patients undergoing liver transplantation are prone to develop numerous infectious complications because of immunosuppression, surgical interventions, and malnutrition. Infections in transplant recipients account for the main cause of mortality and morbidity with rates of up to 80%. The challenges faced in the early post-transplant period tend to be linked to transplant procedures and nosocomial infections commonly in bloodstream, surgical, and intra-abdominal sites. Viral infections represent an additional complication of immunosuppression; they can be donor-derived, reactivated from a latent virus, nosocomial or community-acquired. Bacterial and viral infections in solid organ transplantation are managed by prophylaxis, multi-drug resistant screening, risk assessment, vaccination, infection control and antimicrobial stewardship. The aim of this review was to discuss the epidemiology of bacterial and viral infections in liver transplants, infection control issues, as well as surgical frontiers of ex situ liver perfusion.

Abstract
BACKGROUND Early bacterial infection is a major and severe complication after liver transplantation (LT). The rise of antimicrobial resistance, especially extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE), is a growing concern for these patients. This study aimed to assess the epidemiology of early bacterial infections in a pediatric population, including those caused by multidrug-resistant (MDR) pathogens, and to identify risk factors for infection. METHODS We conducted a monocentric retrospective study including 142 consecutive LTs performed in 137 children between 2009 and 2017. RESULTS Ninety-three bacterial infections occurred after 67 (47%) LTs. Among the 82 isolated pathogens, the most common was Klebsiella pneumoniae (n = 19, 23%). Independent risk factors for early bacterial infection were low weight [odds ratio (OR) = 0.96; 95% confidence interval (CI): 0.9-0.99; P = 0.03] and the presence of a prosthetic mesh (OR = 2.4; 95% CI: 1.1-5.4; P = 0.046). Sixty-one children (45%) carried MDR bacteria and 16 infections were caused by MDR pathogens, especially ESBL-producing K. pneumoniae (n = 12). ESBL-PE stool carriage was associated with ESBL-PE infection (OR = 4.5; 95% CI: 1.4-17.4; P = 0.02). Four children died from an infection, three due to ESBL-producing K. pneumoniae. CONCLUSIONS This study confirmed a shift toward a predominance of Gram-negative early bacterial infections after pediatric LT. The risk factors for infection were low weight and the presence of a prosthetic mesh. ESBL-PE stool carriage was associated with ESBL-PE infection. Adapted antimicrobial prophylaxis and personalized antibiotherapy are mandatory to reduce infection prevalence and mortality.

Abstract
OBJECTIVE Solitary pulmonary nodules after liver transplantation are challenging clinical problems. Herein, we report the causes and clinical courses of resected solitary pulmonary nodules in patients who underwent liver transplantation. METHODS We retrospectively obtained medical records of 68 patients who underwent liver transplantation between March 2009 and June 2016. This study mainly focused on patients with solitary pulmonary nodules observed on computed tomography scans during follow-ups that were conducted until their deaths or February 2019. RESULTS Computed tomography scans revealed solitary pulmonary nodules in 7 of the 68 patients. Definitive diagnoses were obtained using video-assisted lung resection in all seven patients. None experienced major postoperative complications. The final pathologic diagnoses were primary lung cancer in three patients, pulmonary metastases from hepatocellular carcinoma in one patient, invasive pulmonary aspergillosis in one patient, post-transplant lymphoproliferative disorder in one patient, and hemorrhagic infarction in one patient. The three patients with lung cancer were subsequently treated with standard curative resection. CONCLUSIONS Solitary pulmonary nodules present in several serious but potentially curable diseases, such as early-stage lung cancer. Patients who present with solitary pulmonary nodules after liver transplantation should be evaluated by standard diagnostic procedures, including surgical biopsy if necessary.

Abstract
BACKGROUND Health care-associated infection (HAI) represent a global health problem with an increase in hospital stays, deaths, and monetary costs. Recipients of solid organ transplants are a population at risk. The objectives of the study were to characterize the incidence of HAI in renal and hepatic transplant recipients as well as to compare them with the population without transplants in intensive care units (ICU). METHODS The data on the incidence of HAI, localization, microorganisms, and demographics were taken from the patients admitted between the years 2013 to 2018 (n = 4307) from the registration of the Project for the Reduction of Nosocomial Infection in Intensive Care Units. The variables were compared with those of renal transplant (n = 96) and liver transplants (n = 68) recipients. RESULTS Renal transplant recipients showed 26% incidence of HAI. The most frequent were surgical site infection (SSI), urinary tract infection, and primary bacteremia; the most frequent microorganism was Staphylococcus spp, mortality 3.8%. Liver transplant recipients showed 41% incidence of HAI. The most frequent were tracheobronchitis associated with mechanical ventilation, SSI, and primary bacteremia; the most frequent microorganism was Staphylococcus spp, mortality 37%. The population without transplants in the ICU showed 17% incidence of HAI. The most frequent were respiratory infections associated with mechanical ventilation, primary bacteremia, and SSI; the most frequent microorganism was Acinetobacter spp, mortality 21%. CONCLUSIONS HAI in recipients of solid organ transplants (renal and hepatic) have a higher incidence than in a population without transplants. The location and causal microorganisms have particularities that must be taken into account for the development of prevention protocols.

Abstract
Purpose In this study, we aimed to compare the efficacy of combined ceftizoxime with ampicillin-sulbactam versus combined gentamicin with ampicillin-sulbactam as prophylactic antibiotic regimen in preventing early bacterial PTIs in liver TX recipients at a referral center. Patients and methods All patients older than 18 years who had undergone liver TX at Abu-Ali Sina transplantation center in Shiraz, Iran from July 2018 to April 2019 were included in this study. In a single-blinded manner, the participants randomly received either combined intravenous ceftizoxime plus ampicillin-sulbactam (ceftizoxime group) or gentamicin plus ampicillin-sulbactam (gentamicin group) as prophylactic antibiotic regimen before the incision of the surgery, which was continued for 48 hrs after liver Tx. The rate and type of bacterial infections, length of hospital and intensive care unit (ICU) stay, mortality rate, and kidney function were assessed during 1 month following liver TX in the two groups. Results Two hundred and thirty patients were divided into two groups. One patient in the gentamicin group and five in the ceftizoxime group were excluded due to emergency exploratory laparotomy within the first 3 days after transplantation. The rate of bacterial infections during the first month after transplantation was 25.4%. This rate was significantly lower in the gentamicin group (13.16%) in comparison to the ceftizoxime group (38.18%) (P value<0.01), based on the univariate logistic regression analysis. Length of ICU and hospital stay and also mortality rate were significantly lower in the gentamicin group (P value <0.01). There was no significant difference regarding kidney function between the two groups (P value = 0.16). Conclusion Our results suggested that gentamicin can be considered as a promising agent in prophylactic antibiotic regimen for patients undergoing liver TX. Trial registration The study was registered at the Iranian Registry of Clinical Trials (IRCT20120731010453N2; http://www.irct.ir/).

Abstract
BACKGROUND The aim of this study was to classify ischemia-type biliary lesions after liver transplantation according to their imaging findings and severity of clinical manifestations and to analyze the relationship between such classification and prognosis. MATERIAL AND METHODS We collected clinical data of patients with ischemia-type biliary lesions (ITBL) after liver transplantation in the Organ Transplantation Center, the First Central Hospital of Tianjin, from August 2012 to July 2013; all patients were classified according to their imaging findings and relevant clinical data to analyze the relationship between their classification and prognosis. RESULTS The mean postoperative survival time, as well as the 1-, 3-, and 5-year survival rate, in Group ITBL showed statistical significance when compared with those in Group NITBL (log rank=12.13, P<0.001), but the mean postoperative survival times among the mild, moderate, and severe ITBL cases showed no statistical significance. The incidence rates of 1-, 3-, and 5-year adverse prognosis in Group ITBL showed statistical significance when compared with Group NITBL with <2% patients who had anastomotic biliary obstruction (log rank=277.06, P<0.001), among which the difference in the incidence rate of adverse prognosis between severe and moderate ITBL cases showed no statistical significance. The difference in the incidence rate of adverse prognosis between mild and moderate ITBL cases showed statistical significance (log rank=6.01, P=0.014), and the difference in the incidence rate of adverse prognosis between mild and severe ITBL cases showed statistical significance (log rank=10.98, P=0.001). CONCLUSIONS ITBL classification based on the severity of biliary imaging and bilirubin level can predict the prognosis of ITBL.
