RESUMO

BACKGROUND AND AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD) recurrence after liver transplantation (LT) seems unavoidable and gradual. We aimed to evaluate the diagnostic accuracy in the post-LT setting of patients transplanted for metabolic dysfunction-associated steatohepatitis (MASH) of recurrent hepatic steatosis and fibrosis identified with FibroScan, compared to biopsy findings. METHODS: This prospective cohort study included adults transplanted for MASH between 2010 and 2022 in three LT centres in Spain who underwent FibroScan and biopsy at least 1-year after LT. RESULTS: In total, 44 patients transplanted for MASH after LT were included. The median time from LT to biopsy and FibroScan was 24.5 (interquartile range [IQR]:16-46) and 26.0 (IQR: 16.8-41.5) months, respectively. The median time between biopsy and FibroScan was 2.0 (IQR: 0-5) months. On FibroScan, significant steatosis was diagnosed in about half of the patients (n = 21, 47.7%), yet advanced fibrosis in only two cases (4.6%). On biopsy, a quarter of biopsied patients (n = 11, 25%) had a MASH diagnosis, two (4.6%) with significant fibrosis and one (2.3%) with cirrhosis. All patients with liver stiffness measurement (LSM) values <8 kPa (n = 35, 79.5%) had a fibrosis stage ≤F1 (negative predictive value = 100%). The combination of post-LT hypertension (odds ratio [OR]: 12.0, 95% confidence interval [CI]: 1.8-80.4, p = .010) and post-LT dyslipidaemia (OR: 7.9, 95% CI: 1.3-47.1, p = .024) with LSM (OR: 1.7, 95% CI: 1.1-2.8, p = .030) was independently associated with MASLD. CONCLUSIONS: Although biopsy remains the gold standard for detecting fibrosis, our results suggest that LSM values <8 kPa after LT for MASH are strongly correlated with absence of significant/advanced fibrosis.

RESUMO

INTRODUCTION: The multiparametric nature of recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) still leads to uncertainty with its practical management. This study aims to characterize the main posttransplant recurrence patterns of HCC and to explore the therapeutic modalities targeting recurrence. METHODS: Consecutive patients who underwent LT for HCC at a single tertiary center were analyzed. The time from first recurrence to death was investigated for each site of presentation. The impact of each recurrence-targeted treatment on survival was studied. RESULTS: Of 660 patients with HCC, any recurrence occurred in 96 (15.4%) patients with a median time to recurrence of 20.0 months (95% CI: 15.6-23.8). Patients recurred across different patters including solitary distant locations (30.8%, n = 28), liver only (24.2%, n = 22), lung (18.7%, n = 17), multi-organ disease (17.6%, n = 16), and bone (8.8%, n = 8). Multi-organ and bone recurrences had the poorest survival, while solitary distant lesions and pulmonary recurrences had the best outcomes. Each treatment modality carried a distinctive survival. CONCLUSIONS: Patients recurred across 3 patterns with different prognostic implications. The benefit of each treatment option on distinct recurrence patterns appears to be influenced by the biological behavior inherent in the recurrence pattern itself.

RESUMO

The gap between organ supply and demand in liver transplantation remains large in most parts of the world. One strategy to increase the donor pool is to use grafts infected with HCV, HBV, and/or HIV viruses. We aimed to explore the current use of HBsAg-positive liver grafts worldwide. A prospective cross-sectional web-based survey was designed, with a total of 28 queries, assessing national and local regulations, center experience, and center-specific experience related to the topic, and sent to all members of International Liver Transplantation Society, European Association for the Study of the Liver, and American Association for the Study of the Liver, and promoted on social media. A total of 135 liver transplant centers answered the survey: 38% from WHO European Regions, 39% from American regions, and 9.7% from South-East Asian regions. Most of the participating centers (67.3%) had been performing liver transplantation for over 15 years, with a mean of 66.5 liver transplants per year, and 54% also performed living-donor liver transplants. HBV-related disease was the indication for liver transplantation in an average of 15% of all liver transplantation cases. Regarding national and/or regional regulations, 40% of the centers reported that the use of HBsAg-positive donors was permitted, and an additional 20% could use them under special circumstances. Thirty-two centers (31%) had previously used HBsAg-positive donors. Among these centers, 62.5% conducted living-donor liver transplants and showed an increased inclination toward the use of HBsAg-positive grafts in centers with elevated waitlist mortality. HBsAg-positive donors are underutilized worldwide. The use of HBsAg-positive liver grafts could help to increase the donor pool, particularly in highly endemic areas.

RESUMO

BACKGROUND & AIMS: Several hepatocellular carcinoma (HCC) risk-models have been developed to individualise patient surveillance following sustained viral response (SVR) in Hepatitis C Virus patients. Validation of these models in different cohorts is an important step to incorporate a more personalised risk assessment in clinical practice. We aimed at applying these models to stratify the risk in our patients and potentially determine cost-saving associated with individualised HCC risk-stratification screening strategy. METHODS: Patients with baseline F3-4 fibrosis treated with new oral direct-acting antivirals who had reached a SVR were regularly followed as part of the HCC surveillance strategy. Six models were applied: Pons, aMAP, Ioannou, HCC risk, Alonso and Semmler. Validation of the models was performed based on sensitivity and the proportion of patients labelled as "high risk". RESULTS: After excluding 557 with less than 3 fibrosis, 12 without SVR, 18 with a follow up (FU) <1 year, 17 transplant recipients, 16 lost to FU and 31 with HCC at time of antiviral therapy, our cohort consisted of 349 F3-4 SVR patients. Twenty-three patients (6.6%) developed HCC after a median FU of 5.12 years. The sensitivity of the different models varied between 0.17 (Semmler7noalcohol) and 1 (Alonso A and aMAP). The lowest proportion of high-risk patients corresponded to the Semmler-noalcohol model (5%). Sixty-three and 90% of the Alonso A and aMAP patients, respectively were labelled as high risk. The most reliable HCC risk-model applied to our cohort to predict HCC development is the Alonso model (based on fibrosis stage assessed by liver stiffness measurements or Fibrosis-4 index (FIB-4) at baseline and after 1 year, and albumin levels at 1 year) with a-100% sensitivity in detecting HCC among those at high risk and 63% labelled as high risk. The application of the model would have saved the cost of 1290 ultrasound no longer being performed in the 37% low-risk group. CONCLUSION: In our cohort, the Alonso A model allows the most reliable reduction in HCC screening resulting in safely stopping life-long monitoring in about a third of F3-F4 patients achieving SVR with DAAs.

RESUMO

Recommended post-liver transplant (LT) prophylaxis in patients with hepatitis delta includes a nucleos(t)ide analogue (NA) and anti-hepatitis B immunoglobulin (HBIG) indefinitely. We analysed the use of HBIG in real-life clinical practice and its impact on HBV/HDV recurrence in 174 HDV-related LT patients from 10 Spanish liver transplant centres (1988-2018). Median post-LT follow-up was 7.8 (2.3-15.1) years and patient survival at 5 years was 90%. Most patients (97%) received HBIG in the immediate post-LT, but only 42% were on HBIG at the last control. Among those discontinuing HBIG, the median time on treatment was 18 (7-52) months. Post-LT HBsAg+ was detected in 16 (9%) patients and HBV-DNA in 12 (7%). Despite HBsAg positivity, HDV recurrence was reported only in three patients (1.7%), all of whom were not receiving NA and had discontinued HBIG. Our data suggest that a finite HBIG prophylaxis in HDV-LT is feasible, especially if high-barrier NAs are used.

RESUMO

Background: Despite the WHO's report of 24 available SARS-CoV-2 vaccines, limited data exist regarding vaccination policies for liver transplant (LT) patients. To address this, we conducted a global multi-society survey (EASL-ESOT-ELITA-ILTS) in LT centers. Methods: A digital questionnaire assessing vaccine policies, safety, efficacy, and center data was administered online to LT centers. Results: Out of 168 responding centers, 46.4%, 28%, 13.1%, 10.7%, and 1.8% were from European, American, Western Pacific, Southeast Asian, and Eastern Mediterranean Regions. Most LT centers prioritized COVID-19 vaccine access for LT patients (76%) and healthcare workers (86%), while other categories had lower priority (30%). One-third of responders recommended mRNA vaccine exclusively, while booster doses were widely recommended (81%). One-third conducted post-vaccine liver function tests post COVID-19 vaccine. Only 16% of centers modified immunosuppression, and mycophenolate discontinuation or modification was the main approach. Side effects were seen in 1 in 1,000 vaccinated patients, with thromboembolism, acute rejection, and allergic reaction being the most severe. mRNA showed fewer side effects (-3.1, p = 0.002). Conclusion: COVID-19 vaccines and booster doses were widely used among LT recipients and healthcare workers, without a specific vaccine preference. Preventative immunosuppression adjustment post-vaccination was uncommon. mRNA vaccines demonstrated a favorable safety profile in this population.

RESUMO

After a 1-y absence due to the coronavirus disease 2019 pandemic, the 26th Annual Congress of the International Liver Transplantation Society was held from May 15 to 18, 2021, in a virtual format. Clinicians and researchers from all over the world came together to share their knowledge on all the aspects of liver transplantation (LT). Apart from a focus on LT in times of coronavirus disease 2019, featured topics of this year's conference included infectious diseases in LT, living donation, machine perfusion, oncology, predictive scoring systems and updates in anesthesia/critical care, immunology, radiology, pathology, and pediatrics. This report presents highlights from invited lectures and a review of the select abstracts. The aim of this report, generated by the Vanguard Committee of International Liver Transplantation Society, is to provide a summary of the most recent developments in clinical practice and research in LT.

RESUMO

BACKGROUND: Prehabilitation programs as part of ERAS protocols are being increasingly used in multiple surgeries, improving postoperative outcomes. Data regarding prehabilitation programs in patients awaiting liver transplantation and their outcomes is scarce. OBJECTIVES: To identify whether prehabilitation programs based on exercise training conducted prior to liver transplantation improve short-term postoperative outcomes, and to provide expert panel recommendations. DATA SOURCES: Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS: Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. Studies included those evaluating postoperative outcomes, as well as those evaluating functional outcomes. PROSPERO ID: CRD42021236305. RESULTS: Of the 170 studies screened, only one assessed the primary objective. Most studies focus on the preoperative impact of exercise training on aerobic capacity, muscle mass and/or strength, showing positive effects and no significant adverse events, but are underpowered and with heterogenous designs and interventions. The non-randomized observational study which assessed relevant postoperative outcomes, showed a non-significant trend towards reduced 90-day readmission rate and shorter length of stay in the prehabilitation group. CONCLUSIONS: Prehabilitation prior to liver transplantation is unlikely to be harmful, and likely to have short term benefits on functional status. We cautiously recommend prehabilitation on the basis of absence of harm and possibility of benefit (Quality of Evidence; Very Low | Grade of Recommendation; Low).

RESUMO

Liver transplant in patients with prior nonhepatic cancer is a matter of concern, needing further research, development, and consensus guidelines. This International Liver Transplantation Society/Sociedad Española De Trasplante Hepático consensus conference document focuses on the role of liver transplantation in patients with a prior history of nonhepatic cancer. This document addresses (1) the evaluation of transplant candidates with prior cancers based on the assessment of prognosis, the natural history of individual cancers, and the emerging role for circulating DNA and minimal residual disease in these patients; (2) the impact of prior treatments, including immunotherapy for prior malignancies; and (3) the surveillance of posttransplant cancer recurrence. The consensus statement is based on previously published guidelines, as well as a review of the current, relevant, published literature.

RESUMO

BACKGROUND & AIMS: The incidence and outcomes of coronavirus disease 2019 (COVID-19) in immunocompromised patients are a matter of debate. METHODS: We performed a prospective nationwide study including a consecutive cohort of liver transplant patients with COVID-19 recruited during the Spanish outbreak from 28 February to 7 April, 2020. The primary outcome was severe COVID-19, defined as the need for mechanical ventilation, intensive care, and/or death. Age- and gender-standardised incidence and mortality ratios (SIR and SMR) were calculated using data from the Ministry of Health and the Spanish liver transplant registry. Independent predictors of severe COVID-19 among hospitalised patients were analysed using multivariate Cox regression. RESULTS: A total of 111 liver transplant patients were diagnosed with COVID-19 (SIR = 191.2 [95% CI 190.3-192.2]). The epidemiological curve and geographic distribution overlapped widely between the liver transplant and general populations. After a median follow-up of 23 days, 96 patients (86.5%) were admitted to hospital and 22 patients (19.8%) required respiratory support. A total of 12 patients were admitted to the ICU (10.8%). The mortality rate was 18%, which was lower than in the matched general population (SMR = 95.5 [95% CI 94.2-96.8]). Overall, 35 patients (31.5%) met criteria of severe COVID-19. Baseline immunosuppression containing mycophenolate was an independent predictor of severe COVID-19 (relative risk = 3.94; 95% CI 1.59-9.74; p = 0.003), particularly at doses higher than 1,000 mg/day (p = 0.003). This deleterious effect was not observed with calcineurin inhibitors or everolimus and complete immunosuppression withdrawal showed no benefit. CONCLUSIONS: Being chronically immunosuppressed, liver transplant patients have an increased risk of acquiring COVID-19 but their mortality rates are lower than the matched general population. Upon hospital admission, mycophenolate dose reduction or withdrawal could help in preventing severe COVID-19. However, complete immunosuppression withdrawal should be discouraged. LAY SUMMARY: In liver transplant patients, chronic immunosuppression increases the risk of acquiring COVID-19 but it could reduce disease severity. Complete immunosuppression withdrawal may not be justified. However, mycophenolate withdrawal or temporary conversion to calcineurin inhibitors or everolimus until disease resolution could be beneficial in hospitalised patients.

RESUMO

The 25th Annual Congress of the International Liver Transplantation Society was held in Toronto, Canada, from May 15 to 18, 2019. Surgeons, hepatologists, anesthesiologists, critical care intensivists, radiologists, pathologists, and research scientists from all over the world came together with the common aim of improving care and outcomes for liver transplant recipients and living donors. Some of the featured topics at this year's conference included multidisciplinary perioperative care in liver transplantation, worldwide approaches to organ allocation, donor steatosis, and updates in pediatrics, immunology, and radiology. This report presents excerpts and highlights from invited lectures and select abstracts, reviewed and compiled by the Vanguard Committee of International Liver Transplantation Society. This will hopefully contribute to further advances in clinical practice and research in liver transplantation.

RESUMO

BACKGROUND: There is a lack of data on the use of direct-acting antivirals (DAA) on the risk of death and tumoral recurrence in patients with hepatitis C virus (HCV) and hepatocellular carcinoma (HCC) listed for liver transplantation (LT). We aimed to assess the impact of antiviral treatment on mortality and HCC recurrence patients with HCC-HCV. METHODS: This was a retrospective multicenter study of patients with HCC-HCV listed for LT from 2005 to 2015. Patients were divided according to the antiviral treatment received after HCC diagnosis: DAA, interferon (IFN), or no antiviral. Intention-to-treat overall survival and HCC recurrence incidence were compared by the Kaplan-Meier method. Multivariable regression analysis was performed to identify risk factors for outcomes. RESULTS: A total of 1012 HCV-HCC patients were listed for LT during the study period. The median follow-up was 4.0 (interquartile range = 2.3-6.7) years. Mortality was 5.6 (95% confidence interval [CI], 4.3-7.2), 13.1 (95% CI, 11.0-15.7), and 6.2 (95% CI, 5.4-7.2) deaths per 100 person-year among patients treated with DAA, IFN, and antiviral naïve, respectively (P < 0.001). Of the 875 HCV-HCC transplant recipients, the 5-year recurrence-free survival was 93.4%, 84.8%, 73.9% for the pre-LT DAA, pre-LT IFN, and antiviral naïve groups, respectively (P < 0.001). After multivariable regression, the use of pre-LT DAA was not associated to risk of recurrence (hazard ratio = 0.44 [95% CI, 0.19-1.00]). Post-LT DAA was not related to increased risk of recurrence (hazard ratio = 0.62 [95% CI, 0.33-1.16]). CONCLUSIONS: In this multicenter intent-to-treat study, DAA therapy was not found to be a risk factor for mortality or HCC recurrence after adjusting for potential confounders.

RESUMO

Milan criteria are widely used for liver transplantation selection in hepatocellular carcinoma but have been recognized to be too restrictive. Milan-out criteria are increasingly being adopted. Our aim was to analyze if liver transplantation waitlisted Milan-out hepatocellular carcinoma patients have different outcome than Milan patients. METHODS: Retrospective study including all consecutive patients with hepatocellular carcinoma admitted in the waiting list for liver transplantation between January 2012 and January 2015. We included 177 patients, 146 of which eventually transplanted. Downstaging was achieved in the Milan-out cases (n = 29) before waitlisting. RESULTS: From diagnosis to last follow-up, 29% patients died. Survival at 1 and 5 years from diagnosis was 93% and 75%, respectively in the within Milan group compared with 91% and 61% in the Milan-out group (P = 0.03). Treatment failure occurred in 20% of cases due to tumor progression in the waiting list (44%), death on the waiting list (20%), and hepatocellular carcinoma recurrence postliver transplantation (9%). Milan-out criteria was the only variable predictive of treatment failure remaining in the multivariate analysis with a hazard ratio (HR) of 1.7 (HR, 1.7; 95% confidence interval, 1.34-4.55; P = 0.010) and HR of 1.43 (1.23-6.5) in the hepatocellular carcinoma recurrence. CONCLUSIONS: Milan-out criteria are associated with a higher intention-to-treat liver transplantation failure from time of inclusion in the waiting list. However, survival rates are still >50% at 5 years of follow-up.

RESUMO

INTRODUCTION AND OBJECTIVES: Non-alcoholic steatohepatitis (NASH) indication of liver transplant (LT) has increased recently, whereas alcoholic cirrhosis remains a major indication for LT. To characterize NASH-related cases and to compare the post-transplant outcome of these two conditions represents our major objective. MATERIAL AND METHODS: Patients undergoing LT for NASH between 1997 and 2016 were retrieved. Those transplanted between 1997 and 2006 were compared to an "age and LT date" matched group of patients transplanted for alcoholic cirrhosis (ratio 1:2). Baseline features and medium-term outcome measures were compared. RESULTS: Of 1986 LT performed between 1997 and 2016, 40 (2%) were labeled as NASH-related indications. NASH-related cases increased initially (from 0.8% in 1997-2001 to 2.7% in 2002-2006) but remained stable in subsequent years (2.3%). Hepatocellular carcinoma (HCC) prevalence was greater in NASH-vs alcohol-related cirrhosis (40% vs 3%, p=0.001). The incidence of overweight, obesity, arterial hypertension, dyslipidemia, diabetes, hyperuricemia, renal insufficiency and cardiovascular (CV) disease was similar in both groups at 5 years post-LT. Five-year survival was higher in NASH but without reaching statistical significance (83% vs 72%, p=0.21). The main cause of mortality in NASH-LT patients was HCC recurrence. CONCLUSION: Most previously considered cryptogenic cases are actually NASH-cirrhosis. While the incidence of this indication is increasing in many countries, it has remained relatively stable in our Unit, the largest LT center in Spain. HCC is common in these patients and represents a main cause of post-transplant mortality. Metabolic complications, CV-related disease and 5-yr survival do not differ in patients transplanted for NASH vs alcohol.

RESUMO

Nonalcoholic steatohepatitis (NASH), with or without hepatocellular carcinoma, is a growing indication for liver transplantation (LT) worldwide, particularly in the Western world. Patients with NASH typically combine features of metabolic syndrome with cardiovascular comorbidities, which challenge pre-LT evaluation, surgical approaches, post-LT management, and outcomes. Post-LT survival in NASH patients is excellent, similar to that achieved with other indications, particularly in the absence of cardiovascular comorbidities. Although disease recurrence on the liver allograft is common, progression to advanced disease is uncommon, at least in the short term. Whether this holds true with longer follow-up remains to be determined. Owing to the increased prevalence of nonalcoholic fatty liver disease worldwide, along with a shortened organ pool donation in many countries, utilization of donor grafts with hepatic steatosis is now more common. Understanding the limitations of these grafts as well as potential mechanisms to improve graft quality and/or transplant outcome is clue for transplant centers. In this review, we will summarize current data on evaluation of NASH patients and whether it differs from that applied to other candidates, the natural history of NASH both pre- and post-transplantation, emphasizing on waiting list management and recurrence of the original disease in the new graft as well as post-transplant outcome. Finally, we will discuss the current use of steatotic liver donors and strategies to improve outcome when using this type of grafts.

RESUMO

BACKGROUNDS & AIMS: Treating patients with decompensated cirrhosis with direct-acting antiviral (DAA) therapy while on the waiting list for liver transplantation results in substantial improvement of liver function allowing 1 in 4 patients to be removed from the waiting list or delisted, as reported in a previous study promoted by the European Liver and Intestine Transplant Association (ELITA). The aim of this study was to report on clinical outcomes of delisted patients, including mortality risk, hepatocellular carcinoma development and clinical decompensation requiring relisting. METHODS: One hundred and forty-two HCV-positive patients on the liver transplant waiting list for decompensated cirrhosis, negative for hepatocellular carcinoma, between February 2014 and June 2015 were treated with DAA therapy and were prospectively followed up. RESULTS: Forty-four patients (30.9%) were delisted following clinical improvement. This percentage was higher than in the original study because of a number of patients being delisted long after starting DAAs. The median Child-Pugh and MELD score of delisted patients was 5.5 and 9 respectively. Four patients were relisted, because of HCC diagnosis in 1 case and 3 patients developed ascites. One further patient died (2.4%) because of rapidly progressing hepatocellular carcinoma twenty-two months after delisting. Of the 70 patients who received a liver graft, 9 died (13%). CONCLUSIONS: Antiviral therapy allows for a long-term improvement of liver function and the delisting of one-third of treated patients with risk of liver-related complications after delisting being very low.

RESUMO

The association between cytomegalovirus (CMV) reactivation and cardiovascular risk has been reported in solid organ transplant populations; however, it has yet to be assessed in liver transplantation (LT). We aim to evaluate whether CMV reactivation is associated with cardiovascular events (CVE) in HCV-LT patients. LT patients (2010 and 2014) due to HCV cirrhosis were included. Clinically significant CMV (CS-CMV) was defined as viral load (VL) >5000 copies/ml, need of therapy or CMV disease. Baseline variables and endpoint measures (CVE, survival, severe recurrent hepatitis C, de novo tumors, and diabetes) were collected. One hundred and forty patients were included. At LT, a history of AHT was present in 23%, diabetes 22%, tobacco use 45%, obesity 20%, and renal impairment (eGFR < 60 ml/min) in 26.5%. CS-CMV reactivation occurred in 25% of patients. Twenty-six patients (18.5%) developed a CVE. Cox regression analysis revealed two factors significantly associated with CVE: Pre-LT DM [HR = 4.6 95% CI (1.6, 13), P = 0.004] and CS-CMV [HR = 4.7 95% CI (1.8, 12.5), P = 0.002]. CS-CMV was not independently associated with the remaining endpoints except for survival (P = 0.03). In our series, CS-CMV reactivation was associated with a greater risk of developing CVE, thus confirming data from other solid organ transplant populations and emphasizing the need for adequate CMV control.
