Item Acute Inpatient Rehabilitation Functional Outcomes and Disposition After Liver Transplant(Elsevier, 2024-03-16) Willoughby, Meghan E.; Ramsey-Morrow, Jacob L.; Littell, Kyle A.; Hammond, Flora M.; Physical Medicine and Rehabilitation, School of MedicineObjective: To describe the outcomes (change in functional independence and discharge disposition) of patients who after liver transplantation received acute inpatient rehabilitation in a freestanding rehabilitation hospital. Design: A retrospective chart review was conducted of patients admitted to an acute inpatient rehabilitation hospital within 6 months of undergoing liver transplantation between January 2014 and December 2018. Change in function from rehabilitation admission to discharge was measured using FIM Change and FIM Efficiency. Setting: A freestanding rehabilitation hospital. Participants: 107 patients who underwent acute inpatient rehabilitation at a freestanding rehabilitation hospital within 6 months after liver transplantation who met inclusion criteria (N=107). Most were men (71.96%), and the mean age of the patient population was 62.15 years. Interventions: Acute inpatient rehabilitation consisting of at least 3 hours of therapy 5 days a week split between physical therapy, occupational therapy, and speech language pathology services. Main outcome measure: FIM Change, FIM Efficiency, Discharge Disposition. Results: Participants were found to have statistically significant positive FIM Change (P<.00001) and FIM Efficiency (P<.00001). The mean FIM Change and Efficiency were 35.7±11.8 and 2.4±1.0, respectively. 83.2% (n = 89) were ultimately discharged to the community. Conclusion: Acute inpatient rehabilitation provides patients who have received a liver transplant with the opportunity to measurably improve their function and independence, with most patients being able to return home.Item Acute pancreatitis in liver transplant hospitalizations: Identifying national trends, clinical outcomes and healthcare burden in the United States(Baishideng Publishing Group, 2023) Dahiya, Dushyant Singh; Jahagirdar, Vinay; Chandan, Saurabh; Gangwani, Manesh Kumar; Merza, Nooraldin; Ali, Hassam; Deliwala, Smit; Aziz, Muhammad; Ramai, Daryl; Pinnam, Bhanu Siva Mohan; Bapaye, Jay; Cheng, Chin-I; Inamdar, Sumant; Sharma, Neil R.; Al-Haddad, Mohammad; Medicine, School of MedicineBackground: Acute pancreatitis (AP) in liver transplant (LT) recipients may lead to poor clinical outcomes and development of severe complications. Aim: We aimed to assess national trends, clinical outcomes, and the healthcare burden of LT hospitalizations with AP in the United States (US). Methods: The National Inpatient Sample was utilized to identify all adult (≥ 18 years old) LT hospitalizations with AP in the US from 2007-2019. Non-LT AP hospitalizations served as controls for comparative analysis. National trends of hospitalization characteristics, clinical outcomes, complications, and healthcare burden for LT hospitalizations with AP were highlighted. Hospitalization characteristics, clinical outcomes, complications, and healthcare burden were also compared between the LT and non-LT cohorts. Furthermore, predictors of inpatient mortality for LT hospitalizations with AP were identified. All P values ≤ 0.05 were considered statistically significant. Results: The total number of LT hospitalizations with AP increased from 305 in 2007 to 610 in 2019. There was a rising trend of Hispanic (16.5% in 2007 to 21.1% in 2018, P-trend = 0.0009) and Asian (4.3% in 2007 to 7.4% in 2019, p-trend = 0.0002) LT hospitalizations with AP, while a decline was noted for Blacks (11% in 2007 to 8.3% in 2019, P-trend = 0.0004). Furthermore, LT hospitalizations with AP had an increasing comorbidity burden as the Charlson Comorbidity Index (CCI) score ≥ 3 increased from 41.64% in 2007 to 62.30% in 2019 (P-trend < 0.0001). We did not find statistically significant trends in inpatient mortality, mean length of stay (LOS), and mean total healthcare charge (THC) for LT hospitalizations with AP despite rising trends of complications such as sepsis, acute kidney failure (AKF), acute respiratory failure (ARF), abdominal abscesses, portal vein thrombosis (PVT), and venous thromboembolism (VTE). Between 2007-2019, 6863 LT hospitalizations with AP were compared to 5649980 non-LT AP hospitalizations. LT hospitalizations with AP were slightly older (53.5 vs 52.6 years, P = 0.017) and had a higher proportion of patients with CCI ≥ 3 (51.5% vs 19.8%, P < 0.0001) compared to the non-LT cohort. Additionally, LT hospitalizations with AP had a higher proportion of Whites (67.9% vs 64.6%, P < 0.0001) and Asians (4% vs 2.3%, P < 0.0001), while the non-LT cohort had a higher proportion of Blacks and Hispanics. Interestingly, LT hospitalizations with AP had lower inpatient mortality (1.37% vs 2.16%, P = 0.0479) compared to the non-LT cohort despite having a higher mean age, CCI scores, and complications such as AKF, PVT, VTE, and the need for blood transfusion. However, LT hospitalizations with AP had a higher mean THC ($59596 vs $50466, P = 0.0429) than the non-LT cohort. Conclusion: In the US, LT hospitalizations with AP were on the rise, particularly for Hispanics and Asians. However, LT hospitalizations with AP had lower inpatient mortality compared to non-LT AP hospitalizations.Item Admission Factor V Predicts Transplant-Free Survival in Acute Liver Failure(Springer, 2021) Patidar, Kavish R.; Davis, Brian C.; Slaven, James E.; Ghabril, Marwan S.; Kubal, Chandrashekhar A.; Lee, William M.; Stravitz, Richard T.; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public HealthBackground and aims: Traditional laboratory markers are insensitive in distinguishing between patients with acute liver failure (ALF) who will require urgent liver transplantation (LT) from those who will recover spontaneously, particularly within 24 h of presentation. Coagulation factor-V (FV) may improve the accuracy of outcome prediction in ALF due to its predominant synthesis in the liver and short half-life in plasma. Methods: Patients enrolled in the ALF Study Group Registry from a single site had FV determined within 24 h of presentation (Derivation-Cohort). Area under the receiver operating characteristic curves (AUROC) dichotomized by ALF etiology [acetaminophen (APAP) or non-APAP] were constructed to evaluate the diagnostic performance of FV for transplant-free-survival (TFS). Multivariate logistic regression modeling was performed using FV and other clinical variables to predict TFS. Accuracy of FV and multivariable model were performed in a Validation-Cohort from a different site. Results: 90-patients (56% with APAP) were included in the Derivation-Cohort. Median FV was significantly higher in TFS versus those who died/LT (31% vs. 15%, respectively; p = 0.001). When dichotomized by etiology, AUROC for FV was 0.77 for APAP (cutoff, sensitivity, specificity 10.5%, 79%, 69%, respectively) and 0.77 for non-APAP (22%, 85%, 67%, respectively). When the optimal cutoffs for FV in the Derivation-Cohort were applied to the Validation-Cohort (N = 51; 59% with APAP), AUROC for FV was 0.75 for APAP (sensitivity/specificity 81/44) and 0.95 for non-APAP (sensitivity/specificity 90/73). In multivariate analyses, AUROC for FV model was 0.86 in the Derivation-Cohort and 0.90 in the Validation-Cohort. Conclusion: Admission FV may improve selection of patients who are likely to improve without LT.Item Assessment of morbidity and mortality after liver transplantation for primary sclerosing cholangitis(AME, 2024) Ekser, Burcin; Mihaylov, Plamen; Mangus, Richard S.; Surgery, School of MedicineItem Attacking Alcohol-Related Liver Disease by Taxing Alcohol Sales(Wiley, 2021) Tapper, Elliot B.; Parikh, Neehar D.; Liangpunsakul, Suthat; Medicine, School of MedicineItem Bridging to Allotransplantation-Is Pig Liver Xenotransplantation the Best Option?(Wolters Kluwer, 2022) Lamm, Vladimir; Ekser, Burcin; Vagefi, Parsia A.; Cooper, David K. C.; Surgery, School of MedicineIn the past 20 y, the number of patients in the United States who died while waiting for a human donor liver totaled >52 000. The median national wait time for patients with acute liver failure and the most urgent liver transplant listing was 7 d in 2018. The need for a clinical "bridge" to allotransplantation is clear. Current options for supporting patients with acute liver failure include artificial liver support devices, extracorporeal liver perfusion, and hepatocyte transplantation, all of which have shown mixed results with regard to survival benefit and are largely experimental. Progress in the transplantation of genetically engineered pig liver grafts in nonhuman primates has grown steadily, with survival of the pig graft extended to almost 1 mo in 2017. Further advances may justify consideration of a pig liver transplant as a clinical bridge to allotransplantation. We provide a brief history of pig liver xenotransplantation, summarize the most recent progress in pig-to-nonhuman primate liver transplantation models, and suggest criteria that may be considered for patient selection for a clinical trial of bridging by genetically engineered pig liver xenotransplantation to liver allotransplantation.Item The CYP3A5 genotypes of both liver transplant recipients and donors influence the time-dependent recovery of tacrolimus clearance during the early stage following transplantation(Wiley, 2021-10) Huang, Li; Assiri, Abdullah A.; Wen, Peihao; Zhang, Kun; Fan, Junwei; Xing, Tonghai; Liu, Yuan; Zhang, Jinyan; Wang, Zhaowen; Su, Zhaojie; Chen, Jiajia; Xiao, Yi; Wang, Rui; Na, Risi; Yuan, Liyun; Liu, Dehua; Xia, Junjie; Zhong, Lin; Liu, Wanqing; Guo, Wenzhi; Overholser, Brian R.; Peng, Zhihai; Medicine, School of MedicineItem De Novo Malignancy Post Liver Transplantation: A Single Center, Population Controlled Study(Wiley, 2013) Chatrath, Hemant; Berman, Kenneth; Vuppalanchi, Raj; Slaven, James; Kwo, Paul; Tector, A. Joseph; Chalasani, Naga; Ghabril, Marwan; Medicine, School of MedicineBackground: With the growing numbers of liver transplant recipients, it is increasingly important to understand the risks of de novo malignancy after liver transplantation. Aim: To characterize the incidence of de novo malignancy after liver transplantation compared with a control non-transplant population. Methods: We studied 534 Indiana state residents undergoing liver transplantation at our center between 1997 and 2004, followed through August 2010. The incidence and predictors of malignancy were determined. The standardized incidence ratio (SIR) of cancer in our cohort was compared with age-, gender-, and period-matched state population using the Indiana State Cancer Registry. Results: After a mean follow-up of 5.7 ± 3.2 yr, 73 patients (13.7%) developed 80 cancers, with five- and 10-yr incidence rates of 11.7% and 24.8%, respectively. These included 24 (30%) skin, 16 (20%) hematologic, and 40 (50%) solid tumors. The most common solid cancers were aerodigestive. Compared with matched state population, liver transplant recipients had significantly higher incidence of all cancers (SIR: 3.1, 95% CI [Confidence interval]: 2.9-3.2), skin (melanoma) (SIR: 5.8, 95% CI: 4.7-7.0), hematologic (SIR: 7.1, 95% CI: 6.3-8.0), and solid (SIR: 2.7, 95% CI: 2.5-2.8) tumors. Conclusion: There is a significantly increased risk of de novo malignancies after liver transplantation, highlighting the need for surveillance strategies in this population.Item Deep learning for 3D biliary anatomy for living liver donor hepatectomy planning(Wolters Kluwer, 2024-06-01) Ekser, Burcin; Tekin, Akin; Balci, Deniz; Surgery, School of MedicineItem Donor Simvastatin Treatment Is Safe and Might Improve Outcomes After Liver Transplantation: A Randomized Clinical Trial(Wolters Kluwer, 2022) Pagano, Duilio; Bosch, Jaime; Tuzzolino, Fabio; Oliva, Elisabetta; Ekser, Burcin; Zito, Giovanni; Cintorino, Davide; di Francesco, Fabrizio; Petri, Sergio Li; Ricotta, Calogero; Bonsignore, Pasquale; Calamia, Sergio; Magro, Bianca; Trifirò, Gianluca; Alduino, Rossella; Barbara, Marco; Conaldi, Pier Giulio; Gallo, Alessia; Venuti, Francesca; Luca, Angelo; Gruttadauria, Salvatore; Surgery, School of MedicineBackground: The current curative approaches for ischemia/reperfusion injury on liver transplantation are still under debate for their safety and efficacy in patients with end-stage liver disease. We present the SIMVA statin donor treatment before Liver Transplants study. Methods: SIMVA statin donor treatment before Liver Transplants is a monocentric, double-blind, randomized, prospective trial aiming to compare the safety and efficacy of preoperative brain-dead donors' treatment with the intragastric administration of 80 mg of simvastatin on liver transplant recipient outcomes in a real-life setting. Primary aim was incidence of patient and graft survival at 90 and 180 d posttransplant; secondary end-points were severe complications. Results: The trial enrolled 58 adult patients (18-65 y old). The minimum follow-up was 6 mo. No patient or graft was lost at 90 or 180 d in the experimental group (n = 28), whereas patient/graft survival were 93.1% ( P = 0.016) and 89.66% ( P = 0.080) at 90 d and 86.21% ( P = 0.041) and 86.2% ( P = 0.041) at 180 d in the control group (n = 29). The percentage of patients with severe complications (Clavien-Dindo ≥IIIb) was higher in the control group, 55.2% versus 25.0% in the experimental group ( P = 0.0307). The only significant difference in liver tests was a significantly higher gamma-glutamyl transferase and alkaline phosphatase at 15 d ( P = 0.017), ( P = 0.015) in the simvastatin group. Conclusions: Donor simvastatin treatment is safe, and may significantly improve early graft and patient survival after liver transplantation, although further research is mandatory.
