However, the safety of hepatitis B virus core antibody positive(HBcAb+) donors has been controversial. Initial studies were mainly conducted overseas with relatively small numbers of HBcAb+ liver recipients, and there are few relevant reports in the population of China's Mainland. We hypothesized that the safety of HBcAb+ liver grafts is not suboptimal.AIM To evaluate the safety of using hepatitis B virus(HBV) core antibody-positive donors for liver transplantation in Chinese patients.METHODS We conducted a retrospective study enrolling 1071 patients who underwent liver transplantation consecutively from 2005 to 2016 at West China Hospital Liver Transplantation Center. Given the imbalance in several baseline variables, propensity score matching was used, and the outcomes of all recipients were reviewed in this study.RESULTS In the whole population, 230 patients received HBcAb+ and 841 patients received HBcAb negative(HBcAb-) liver grafts. The 1-, 3-and 5-year survival rates in patients and grafts between the two groups were similar(patient survival: 85.8% vs 87.2%, 77.4% vs 81.1%, 72.4% vs 76.7%, log-rank test, P = 0.16; graft survival: 83.2% vs 83.6%, 73.8% vs 75.9%, 70.8% vs 74.4%, log-rank test, P = 0.19). After propensity score matching, 210 pairs of patients were generated. The corresponding 1-, 3-and 5-year patient and graft survival rates showed no significant differences. Further studies illustrated that the post-transplant major complication rates and liver function recovery after surgery were also similar. In addition, multivariate regression analysis in the original cohort and propensity score-matched Cox analysis demonstrated that receiving HBcA b+ liver grafts was not a significant risk factor for long-term survival. These findings were consistent in both HBV surface antigen-positive(HBsAg+) and HBsA g negative(HBsAg-) patients.Newly diagnosed HBV infection had a relatively higher incidence in HBsAg-patients with HBcAb+ liver grafts(13.23%), in which HBV naive recipients suffered most(31.82%), although this difference did not affect patient and graft survival(P = 0.50 and P = 0.49, respectively). Recipients with a high HBV surface antibody(anti-HBs) titer(more than 100 IU/L) before transplantation and antiviral prophylaxis with nucleos(t)ide antiviral agents post-operation, such as nucleos(t)ide antiviral agents, had lower de novo HBV infection risks. CONCLUSION HBcA b+ liver grafts do not affect the long-term outcome of the recipients. Combined with proper postoperative antiviral prophylaxis, utilization of HBcAb+ grafts is rational and feasible.展开更多

METHODS： Between January 1995 and March 2006, 50 patients with end-stage liver disease received LDLT in our department. Donors （at the age of 27-58 years） were healthy and antibody （ABO）-compatible. The protocol of evaluation and selection of donors, choice of surgical methods and strategy applied in the safety evaluation of donors were analyzed. RESULTS： A total of 115 candidate donors were evaluated for LDLT at our center. Of these, 50 underwent successful hepatectomy for living donation. The elimination rate for donors was 43.5%. Positive hepatitis serology and ABO incompatibility were the main factors for excluding candidates. All donors recovered uneventfully. The follow-up time ranged from 3 to 135 too. The incidence of major and minor medical complications was 12.0% and 28.0%, respectively. CONCLUSION： LDLT provides an excellent approach to the problem of donor shortage in China. With a thorough and complete preoperative workup and meticulous intra-and postoperative management, LDLT can be performed with minimal donor morbidity.展开更多

High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.展开更多

The potential way to relieve this issue is to expand the donor pool via extending the donor criteria and make full use of all available grafts. The concept of “no-donor” liver transplantation allows grafts to be recovered from other liver recipients. This review summarizes the current clinical practice of “no-donor” liver transplantation, focusing on the experiences of Chinese transplant teams. Domino liver transplantation was introduced by Furtado in 1995 and implemented later in 2013 in China, and novel donor indications including some essential-to-treat inherited metabolic liver-based diseases have emerged. The concept of cross-auxiliary domino liver transplantation brings a further expansion of the domino liver graft pool, and the first pair of liver transplantation performed “rigorously without donation” was accomplished in our center in 2018. Our experience with this original transplantation procedure is hereby reviewed. In order to further promote and make successful “no-donor” liver transplantation, close co-operation between researchers, surgeons, physicians, organ procurement organizations, as well as ethical committees is required.展开更多

While liver transplantation (LT) provides the best long-term survival, it is constrained by organ scarcity and strict criteria. Liver resection (LR) is often the initial treatment for patients with solitary tumors and preserved liver function. The high recurrence rates associated with LR has prompted the exploration of sequential living donor liver transplantation (seq LDLT) after LR as a strategy for HCC patients with high-risk of recurrence.Methods:We analyzed data from 27 adult patients who underwent seq LDLT after LR for HCC at Kaohsiung Chang Gung Memorial Hospital (KCGMH) between June 1994 and December 2023. Patients were selected based on high-risk histopathological features post-LR or as part of downstaging strategy. Outcomes measured included overall survival (OS) and disease-free survival (DFS).Results:Among 765 HCC patients who underwent LDLT, 204 received LR before LDLT, and 27 underwent seqL DLT. Five patients (19%) underwent living donor liver transplantation (LDLT) following LR as a downstaging strategy while the rest received seqL DLT as a preemptive strategy. The median age was 53.5 years with 85%males. Chronic hepatitis B was the predominant underlying disease (74%). The 1-, 3-, and 5-year OS and DFS rates were 100%, 96.0%, 96.0%and 100%, 96.2%, 96.2%, respectively, with two patients experiencing HCC recurrence. One patient died from HCC recurrence. High-risk histopathological features included microvascular invasion (52%), satellite nodules (15%), multiple tumors (26%), tumors> 5 cm(19%), and a total tumor diameter> 10 cm (7%).Conclusions:Seq LDLT offers a promising, tailored approach for managing HCC with adverse histopathologic features. Combining seq LDLT, downstaging strategies, and multidisciplinary treatments can achieve satisfactory OS and DFS in carefully selected patients, highlighting the need for refined criteria to identify the best candidates.展开更多

文摘To establish practical,evidence-based strategies for noninvasive assessment and referral of patients with metabolic dysfunction-associated steatotic liver disease(MASLD)in Japan,we must address the urgent clinical need for accurate risk stratification and timely specialist intervention.A panel of 11 Japanese hepatology experts conducted a modified Delphi process to evaluate consensus recommendations regarding the use of noninvasive tests(NITs),including the fibrosis-4 index,enhanced liver fibrosis test,Mac-2-binding protein glycosylation isomer,type IV collagen 7S,cytokeratin-18 fragments,and imaging modalities such as ultrasound elastography and magnetic resonance elastography,for MASLD assessment and clinical referral.Practical algorithms were developed based on current Japanese data and panel consensus.The expert panel validated the utility of NITs as reliable tools for identifying patients with MASLD at risk for advanced fibrosis.Sequential use of NITs improved diagnostic accuracy and referral appropriateness while minimizing unnecessary specialist consultations.The proposed algorithms offer stepwise guidance for primary care physicians,supporting efficient,evidence-based decisionmaking.However,prospective longitudinal studies remain necessary for full prognostic validation of NITs in MASLD management.Noninvasive testing algorithms enable effective risk stratification and referral for MASLD in real-world Japanese practice with anticipated benefit for patient outcomes and healthcare systems.Broader adoption and further validation are warranted.
文摘AIM:To detect whether the up-to-seven should be used as inclusion criteria for liver transplantation for hepatocellular carcinoma.METHODS:Between April 2002 and July 2008,220hepatocellular carcinoma(HCC)patients who were diagnosed with HCC and underwent liver transplantation(LT)at our liver transplantation center were included.These patients were divided into three groups according to the characteristics of their tumors(tumor diameter,tumor number):the Milan criteria group(Group 1),the in up-to-seven group(Group 2)and the out up-toseven group(Group 3).Then,we compared long-term survival and tumor recurrence of these three groups.RESULTS:The baseline characteristics of transplant recipients were comparable among these three groups,except for the type of liver graft(deceased donor liver transplant or live donor liver transplantation).There were also no significant differences in the pre-operativeα-fetoprotein level.The 1-,3-,and 5-year overall survival and tumor-free survival rate for the Milan criteriagroup were 94.8%,91.4%,89.7%and 91.4%,86.2%,and 86.2%respectively;in the up-to-seven criteria group,these rates were 87.8%,77.8%,and 76.6%and 85.6%,75.6%,and 75.6%respectively(P<0.05).However,the advanced HCC patients’(in the group out of up-to-seven criteria)overall and tumor-free survival rates were much lower,at 75%,53.3%,and 50%and65.8%,42.5%,and 41.7%,respectively(P<0.01).CONCLUSION:Considering that patients in the up-toseven criteria group exhibited a considerable but lower survival rate compared with the Milan criteria group,the up-to-seven criteria should be used carefully and selectively.
文摘AIM:To validate the"Metroticket"predictor using a large cohort of liver transplantation(LT)patients with hepatocellular carcinoma(HCC)in China.METHODS:In total,230 cases of LT for HCC treatment at our center,from July 2000 to August 2008,were included in the present study.The predicted 1-,3-and 5-year post-LT survival rates were calculated using the Metroticket model(http://89.96.76.14/metroticket/calculator/).The predicted and observed long-term survival rates were then compared and analyzed.RESULTS:The predicted survival rates for all 230cases,as calculated by the Metroticket model,were64.7%and 56.2%at 3 and 5 years,respectively,and the observed survival rates for these patients were71.3%and 57.8%,respectively.For the 23 cases with macrovascular invasion,the predicted 5-year survival rate was 43.5%,whereas the observed 5-year survival rate was only 8.7%.For the 42 cases with microvascular invasion but an absence of macrovascular invasion,the predicted 5-year survival rate was 44.9%,and the observed 5-year survival rate was 50%.For the remaining 165 patients without any vascular invasion,the predicted 5-year survival rate was 65.8%,and the observed 5-year survival rate was 66.7%.CONCLUSION:The Metroticket model can be used to accurately predict survival in HCC-related LT cases with an absence of macrovascular invasion.
文摘BACKGROUND Given the shortage of suitable liver grafts for liver transplantation, proper use of hepatitis B core antibody-positive livers might be a possible way to enlarge the donor pool and to save patients with end-stage liver diseases. However, the safety of hepatitis B virus core antibody positive(HBcAb+) donors has been controversial. Initial studies were mainly conducted overseas with relatively small numbers of HBcAb+ liver recipients, and there are few relevant reports in the population of China's Mainland. We hypothesized that the safety of HBcAb+ liver grafts is not suboptimal.AIM To evaluate the safety of using hepatitis B virus(HBV) core antibody-positive donors for liver transplantation in Chinese patients.METHODS We conducted a retrospective study enrolling 1071 patients who underwent liver transplantation consecutively from 2005 to 2016 at West China Hospital Liver Transplantation Center. Given the imbalance in several baseline variables, propensity score matching was used, and the outcomes of all recipients were reviewed in this study.RESULTS In the whole population, 230 patients received HBcAb+ and 841 patients received HBcAb negative(HBcAb-) liver grafts. The 1-, 3-and 5-year survival rates in patients and grafts between the two groups were similar(patient survival: 85.8% vs 87.2%, 77.4% vs 81.1%, 72.4% vs 76.7%, log-rank test, P = 0.16; graft survival: 83.2% vs 83.6%, 73.8% vs 75.9%, 70.8% vs 74.4%, log-rank test, P = 0.19). After propensity score matching, 210 pairs of patients were generated. The corresponding 1-, 3-and 5-year patient and graft survival rates showed no significant differences. Further studies illustrated that the post-transplant major complication rates and liver function recovery after surgery were also similar. In addition, multivariate regression analysis in the original cohort and propensity score-matched Cox analysis demonstrated that receiving HBcA b+ liver grafts was not a significant risk factor for long-term survival. These findings were consistent in both HBV surface antigen-positive(HBsAg+) and HBsA g negative(HBsAg-) patients.Newly diagnosed HBV infection had a relatively higher incidence in HBsAg-patients with HBcAb+ liver grafts(13.23%), in which HBV naive recipients suffered most(31.82%), although this difference did not affect patient and graft survival(P = 0.50 and P = 0.49, respectively). Recipients with a high HBV surface antibody(anti-HBs) titer(more than 100 IU/L) before transplantation and antiviral prophylaxis with nucleos(t)ide antiviral agents post-operation, such as nucleos(t)ide antiviral agents, had lower de novo HBV infection risks. CONCLUSION HBcA b+ liver grafts do not affect the long-term outcome of the recipients. Combined with proper postoperative antiviral prophylaxis, utilization of HBcAb+ grafts is rational and feasible.

文摘BACKGROUND:Few studies have been performed to assess health-related quality of life(HRQOL)in liver transplantation(LT)patients in the mainland of China.This study aimed to investigate the HRQOL of post-LT patients in a single center.METHODS:HRQOL was evaluated by the SF-36(Chinese version)questionnaire in 60 patients(LT group)who had received LT for benign end-stage liver disease(BELD).Fifty-five patients with BELD(BELD group)and 50 healthy volunteers from the general population(GP group)were also evaluated,and the results were compared among the three groups.RESULTS:There was a significant difference among the three groups in terms of the scores of eight domains in the SF-36(P<0.01).Patients in the BELD group had lower scores in each domain of the SF-36 in comparison with those in the GP group(P<0.025).The LT group had mental health scores equivalent to those of the BELD group(P>0.025),but higher scores for the remaining seven domains(P<0.025).Compared with the GP group,the LT group scored equivalently for role physical,body pain,vitality,social function and role emotion(P>0.025),but had lower scores for the remaining three domains(P<0.025).Lower family income was found to be associated with reduced physical function and mental health scores(P<0.05).Better education was associated with increased mental health scores(P<0.05).CONCLUSIONS:LT patients generally have a good HRQOL although some respects of their HRQOL remains to be improved.Lower family income and poor education are important factors relating to the poor HRQOL of LT patients.
文摘AIM： To discuss the safety of donors during living donor liver transplantation （LDLT） and the authors＇ experience with 50 cases. METHODS： Between January 1995 and March 2006, 50 patients with end-stage liver disease received LDLT in our department. Donors （at the age of 27-58 years） were healthy and antibody （ABO）-compatible. The protocol of evaluation and selection of donors, choice of surgical methods and strategy applied in the safety evaluation of donors were analyzed. RESULTS： A total of 115 candidate donors were evaluated for LDLT at our center. Of these, 50 underwent successful hepatectomy for living donation. The elimination rate for donors was 43.5%. Positive hepatitis serology and ABO incompatibility were the main factors for excluding candidates. All donors recovered uneventfully. The follow-up time ranged from 3 to 135 too. The incidence of major and minor medical complications was 12.0% and 28.0%, respectively. CONCLUSION： LDLT provides an excellent approach to the problem of donor shortage in China. With a thorough and complete preoperative workup and meticulous intra-and postoperative management, LDLT can be performed with minimal donor morbidity.
文摘Biliary complications have always been a dreaded cause of morbidity after living donor liver transplantation.While intrinsic variations in both graft and recipient biliary anatomy remain a significant factor to the difficulty of biliary reconstruction,our institution has taken advantage of its high volume of cases to critically review and evaluate modifiable operative risk factors,in particular,our surgical protocols.We present herein,the evolution of our reconstructive biliary technique from conventional methods to our current standard of microsurgical biliary reconstruction for both graft and recipient ducts.Over this period of transition,our center has created a classification system for biliary reconstruction that decreased the biliary complication rates from 40.0%to 10.2%.

文摘BACKGROUND:Donor safety has always been a major concern and potential risk to the donor must be balanced against recipient benefit.However,lack of a standardized and uniform evaluation of perioperative complications is a serious limitation of the evaluation of donor morbidity.This study was designed to evaluate the outcomes of donors in adult living donor liver transplantation(LDLT)using the newer Clavien classification system in a single center in China.METHODS:We prospectively analyzed the outcomes of 132 consecutive living liver donors from 2005 to 2008 using the newer Clavien classification system.The preoperative,intraoperative and postoperative data of the donors were collected and analyzed Ordinal regression was used to analyze the ordered grades of complications.RESULTS:Ninety-four(71.2%)of the donors developed postoperative complications of grade I(n=45,34.1%),grade II(n=39,29.5%)and grade III(n=10,7.6%).There was no death or grade IV morbidity.Hepatic functional impairment and pleural effusion were the most frequent morbidities for living donors.Fifty-three donors(40.1%)developed hepatic functional impairment of grade I(n=40,31.1%)and grade II(n=13,10.0%).The ICU stay(7.8±1.8 days)and length of hospital stay(17.7±4.6 days)were significantly longer in donors with grade III than others.Furthermore,ordinal logistic regression revealed that donor’s older age(>40 years)and right hepatectomy were associated with morbidity.In addition,only preoperative total bilirubin(within the normal range)and postoperative nadir serum phosphorus were independently associated with hepatic functional impairment.The receiveroperator characteristic curve revealed that preoperative total bilirubin>18.0μmol/L and postoperative nadir of serum phosphorus<1 mg/dL may lead to more severe hepatic functional impairment.CONCLUSIONS:Despite the fact that donors are relatively safe to undergo hepatectomy,many living donors still experience postoperative morbidity.Meticulous technical and preoperative donor evaluation and treatment are sure to reduce the incidence of complications.

文摘Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.
文摘BACKGROUND Hydatid cyst disease(HCD)is common in certain locations.Surgery is associated with postoperative biliary fistula(POBF)and recurrence.The primary aim of this study was to identify whether occult cysto-biliary communication(CBC)can predict recurrent HCD.The secondary aim was to assess the role of cystic fluid bilirubin and alkaline phosphatase(ALP)levels in predicting POBF and recurrent HCD.AIM To identify whether occult CBC can predict recurrent HCD.The secondary aim was to assess the role of cystic fluid bilirubin and ALP levels in predicting POBF and recurrent HCD.METHODS From September 2010 to September 2016,a prospective multicenter study was undertaken involving 244 patients with solitary primary superficial stage cystic echinococcosis 2 and cystic echinococcosis 3b HCD who underwent laparoscopic partial cystectomy with omentoplasty.Univariable logistic regression analysis assessed independent factors determining biliary complications and recurrence.RESULTS There was a highly statistically significant association(P≤0.001)between cystic fluid biochemical indices and the development of biliary complications(of 16 patients with POBF,15 patients had high cyst fluid bilirubin and ALP levels),where patients with high bilirubin-ALP levels were 3405 times more likely to have biliary complications.There was a highly statistically significant association(P≤0.001)between biliary complications,biochemical indices,and the occurrence of recurrent HCD(of 30 patients with recurrent HCD,15 patients had high cyst fluid bilirubin and ALP;all 16 patients who had POBF later developed recurrent HCD),where patients who developed biliary complications and high bilirubin-ALP were 244.6 and 214 times more likely to have recurrent hydatid cysts,respectively.CONCLUSION Occult CBC can predict recurrent HCD.Elevated cyst fluid bilirubin and ALP levels predicted POBF and recurrent HCD.
文摘With the advances in transplant oncology in recent years, the role of liver transplantation has expanded to make curative treatment a possibility for a wider patient population. We highlight strategies in Hong Kong, China that have enabled preoperative prognostication for judicious patient selection, downstaging therapy to definitive treatment, and postoperative therapies that have provided a growing role for liver transplantation in patients with more advanced hepatocellular carcinoma.

文摘Liver transplantation is hindered by organ shortage. The potential way to relieve this issue is to expand the donor pool via extending the donor criteria and make full use of all available grafts. The concept of “no-donor” liver transplantation allows grafts to be recovered from other liver recipients. This review summarizes the current clinical practice of “no-donor” liver transplantation, focusing on the experiences of Chinese transplant teams. Domino liver transplantation was introduced by Furtado in 1995 and implemented later in 2013 in China, and novel donor indications including some essential-to-treat inherited metabolic liver-based diseases have emerged. The concept of cross-auxiliary domino liver transplantation brings a further expansion of the domino liver graft pool, and the first pair of liver transplantation performed “rigorously without donation” was accomplished in our center in 2018. Our experience with this original transplantation procedure is hereby reviewed. In order to further promote and make successful “no-donor” liver transplantation, close co-operation between researchers, surgeons, physicians, organ procurement organizations, as well as ethical committees is required.

文摘Objective:Sex-specific differences are observed in various liver diseases,but the influence of sex on the outcomes of hepatocellular carcinoma(HCC)after liver transplantation(LT)remains to be determined.This study is the first Chinese nationwide investigation of the role of sex in post-LT outcomes in patients with HCC.Methods:Data for recipients with HCC registered in the China Liver Transplant Registry between January 2015 and December 2020 were analyzed.The associations between donor,recipient,or donor-recipient transplant patterns by sex and the post-LT outcomes were studied with propensity score matching(PSM).The survival associated with different sex-based donor-recipient transplant patterns was further studied.Results:Among 3,769 patients enrolled in this study,the 1-,3-,and 5-year overall survival(OS)rates of patients with HCC after LT were 96.1%,86.4%,and 78.5%,respectively,in female recipients,and 95.8%,79.0%,and 70.7%,respectively,in male recipients after PSM(P=0.009).However,the OS was comparable between recipients with female donors and male donors.Multivariate analysis indicated that male recipient sex was a risk factor for post-LT survival(HR=1.381,P=0.046).Among the donor-recipient transplant patterns,the male-male donor-recipient transplant pattern was associated with the poorest post-LT survival(P<0.05).Conclusions:Our findings highlighted that the post-LT outcomes of female recipients were significantly superior to those of male recipients,and the male-male donor-recipient transplant pattern was associated with the poorest post-LT survival.Livers from male donors may provide the most benefit to female recipients.Our results indicate that sex should be considered as a critical factor in organ allocation.

文摘Background:Normal bile is sterile.Studies have shown that cholangitis after liver transplantation(LT)was associated with a relatively poor prognosis.It remains unclear whether the bacteriobilia or fungibilia impact the patient outcomes in LT recipients,especially with donation after circulatory death(DCD)allografts,which was correlated with a higher risk of allograft failure.Methods:This retrospective study included 139 LT recipients of DCD grafts from 2019 to 2021.All patients were divided into two groups according to the presence or absence of bacteriobilia or fungibilia.The prevalence and microbial spectrum of postoperative bacteriobilia or fungibilia and its possible association with outcomes,especially hospital stay were analyzed.Results:Totally 135 and 171 organisms were isolated at weeks 1 and 2,respectively.Among all patients included in this analysis,83(59.7%)developed bacteriobilia or fungibilia within 2 weeks posttransplantation.The occurrence of bacteriobilia or fungibilia[β=7.43,95%CI(confidence interval):0.02 to 14.82,P=0.049],particularly the detection of Pseudomonas(β=18.84,95%CI:6.51 to 31.07,P=0.003)within 2 weeks post-transplantation was associated with a longer hospital stay.However,it did not affect the graft and patient survival.Conclusions:The occurrence of bacteriobilia or fungibilia,particularly Pseudomonas within 2 weeks posttransplantation,could influence the recovery of liver function and was associated with prolonged hospital stay but not the graft and patient survival.
文摘Background:Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. While liver transplantation (LT) provides the best long-term survival, it is constrained by organ scarcity and strict criteria. Liver resection (LR) is often the initial treatment for patients with solitary tumors and preserved liver function. The high recurrence rates associated with LR has prompted the exploration of sequential living donor liver transplantation (seq LDLT) after LR as a strategy for HCC patients with high-risk of recurrence.Methods:We analyzed data from 27 adult patients who underwent seq LDLT after LR for HCC at Kaohsiung Chang Gung Memorial Hospital (KCGMH) between June 1994 and December 2023. Patients were selected based on high-risk histopathological features post-LR or as part of downstaging strategy. Outcomes measured included overall survival (OS) and disease-free survival (DFS).Results:Among 765 HCC patients who underwent LDLT, 204 received LR before LDLT, and 27 underwent seqL DLT. Five patients (19%) underwent living donor liver transplantation (LDLT) following LR as a downstaging strategy while the rest received seqL DLT as a preemptive strategy. The median age was 53.5 years with 85%males. Chronic hepatitis B was the predominant underlying disease (74%). The 1-, 3-, and 5-year OS and DFS rates were 100%, 96.0%, 96.0%and 100%, 96.2%, 96.2%, respectively, with two patients experiencing HCC recurrence. One patient died from HCC recurrence. High-risk histopathological features included microvascular invasion (52%), satellite nodules (15%), multiple tumors (26%), tumors> 5 cm(19%), and a total tumor diameter> 10 cm (7%).Conclusions:Seq LDLT offers a promising, tailored approach for managing HCC with adverse histopathologic features. Combining seq LDLT, downstaging strategies, and multidisciplinary treatments can achieve satisfactory OS and DFS in carefully selected patients, highlighting the need for refined criteria to identify the best candidates.
文摘BACKGROUND Acute liver failure(ALF)is a life-threatening multisystemic condition with high short-term mortality.With the growing prevalence of obesity and metabolic syndrome,it is important to investigate the clinical implications of high body mass index(BMI)on survival outcomes in ALF.AIM To explore the impact of overweight and obesity on the clinical outcomes of patients with ALF.METHODS A retrospective observational cohort study was conducted involving patients with ALF admitted to the Johns Hopkins Health System between January 1,2000 and May 1,2020.We performed Cox proportional hazards regression to identify outcomes,including the need for liver transplantation(LT)or all-cause mortality.RESULTS A total of 196 patients were included,the median age was 43.5 years,63.3%were female,and 59.7%were of Caucasian ethnicity.Acetaminophen-induced ALF was the most common etiology(45%).The mean BMI was significantly greater among patients who underwent LT or died(29.64 kg/m^(2)vs 26.59 kg/m^(2),P=0.008)than among survivors.Patients with overweight and obesity had a higher risk of all-cause mortality or need for LT by 2.22-fold(95%CI:1.30-3.78)and 2.04-fold(95%CI:1.29-3.39),respectively.Elevated BMI was associated with renal failure and higher grades of hepatic encephalopathy.Derangements in serologic markers,including alanine transaminase,lactate,and ammonia,were associated with a mortality risk or need for LT.CONCLUSION In this large,retrospective study,with a diverse cohort of United States patients,Overweight and obese were independently associated with an increased risk of all-cause mortality or need for LT.This work highlights the importance of closely monitoring ALF patients who are overweight or obese for adverse complications and measures to improve outcomes in this vulnerable patient population.
