Recent outcomes of liver transplantation for Budd-Chiari syndrome: A study of the European Liver Transplant Registry (ELTR) and affiliated centers.

BACKGROUND AND AIMS: Management of Budd-Chiari syndrome (BCS) has improved over the last decades. The main aim was to evaluate the contemporary post-liver transplant (post-LT) outcomes in Europe. APPROACH AND RESULTS: Data from all patients who underwent transplantation from 1976 to 2020 was obtained from the European Liver Transplant Registry (ELTR). Patients < 16 years, with secondary BCS or HCC were excluded. Patient survival (PS) and graft survival (GS) before and after 2000 were compared. Multivariate Cox regression analysis identified predictors of PS and GS after 2000. Supplemental data was requested from all ELTR-affiliated centers and received from 44. In all, 808 patients underwent transplantation between 2000 and 2020. One-, 5- and 10-year PS was 84%, 77%, and 68%, and GS was 79%, 70%, and 62%, respectively. Both significantly improved compared to outcomes before 2000 ( p < 0.001). Median follow-up was 50 months and retransplantation rate was 12%. Recipient age (aHR:1.04,95%CI:1.02-1.06) and MELD score (aHR:1.04,95%CI:1.01-1.06), especially above 30, were associated with worse PS, while male sex had better outcomes (aHR:0.63,95%CI:0.41-0.96). Donor age was associated with worse PS (aHR:1.01,95%CI:1.00-1.03) and GS (aHR:1.02,95%CI:1.01-1.03). In 353 patients (44%) with supplemental data, 33% had myeloproliferative neoplasm, 20% underwent TIPS pre-LT, and 85% used anticoagulation post-LT. Post-LT anticoagulation was associated with improved PS (aHR:0.29,95%CI:0.16-0.54) and GS (aHR:0.48,95%CI:0.29-0.81). Hepatic artery thrombosis and portal vein thrombosis (PVT) occurred in 9% and 7%, while recurrent BCS was rare (3%). CONCLUSIONS: LT for BCS results in excellent patient- and graft-survival. Older recipient or donor age and higher MELD are associated with poorer outcomes, while long-term anticoagulation improves both patient and graft outcomes.

International multicenter study of ultralow graft-to-recipient weight ratio grafts in adult living donor liver transplantation.

Decreasing the graft size in living donor liver transplantation (LDLT) increases the risk of early allograft dysfunction. Graft-to-recipient weight ratio (GRWR) of 0.8 is considered the threshold. There is evidence that smaller volume grafts may also provide equally good outcomes, the cut-off of which remains unknown. In this retrospective multicenter study, 92 adult LDLTs with a final GRWR ≤0.6 performed at 12 international liver transplant centers over a 3-year period were included. Perioperative data including preoperative status, portal flow hemodynamics (PFH) and portal flow modulation, development of small for size syndrome (SFSS), morbidity, and mortality was collated and analyzed. Thirty-two (36.7%) patients developed SFSS and this was associated with increased 30-day, 90-day, and 1-year mortality. The preoperative model for end-stage liver disease and inpatient status were independent predictors for SFSS (P < .05). Pre-liver transplant renal dysfunction was an independent predictor of survival (hazard ratio 3.1; 95% confidence intervals 1.1, 8.9, P = .035). PFH or portal flow modulation were not predictive of SFSS or survival. We report the largest ever multicenter study of LDLT outcomes using ultralow GRWR grafts and for the first time validate the International Liver Transplantation Society-International Living donor liver transplantation study group-Liver Transplantation Society of India consensus definition and grading of SFSS. Preoperative recipient condition rather than GRWR and PFH were independent predictors of SFSS. Algorithms to predict SFSS and LT outcomes should incorporate recipient factors along with GRWR.

Development of a model to predict the risk of early graft failure after adult-to-adult living donor liver transplantation: An ELTR study.

Graft survival is a critical end point in adult-to-adult living donor liver transplantation (ALDLT), where graft procurement endangers the lives of healthy individuals. Therefore, ALDLT must be responsibly performed in the perspective of a positive harm-to-benefit ratio. This study aimed to develop a risk prediction model for early (3 months) graft failure (EGF) following ALDLT. Donor and recipient factors associated with EGF in ALDLT were studied using data from the European Liver Transplant Registry. An artificial neural network classification algorithm was trained on a set of 2073 ALDLTs, validated using cross-validation, tested on an independent random-split sample (n=518), and externally validated on United Network for Organ Sharing Standard Transplant Analysis and Research data. Model performance was assessed using the AUC, calibration plots, and decision curve analysis. Graft type, graft weight, level of hospitalization, and the severity of liver disease were associated with EGF. The model ( http://ldlt.shinyapps.io/eltr_app ) presented AUC values at cross-validation, in the independent test set, and at external validation of 0.69, 0.70, and 0.68, respectively. Model calibration was fair. The decision curve analysis indicated a positive net benefit of the model, with an estimated net reduction of 5-15 EGF per 100 ALDLTs. Estimated risks>40% and<5% had a specificity of 0.96 and sensitivity of 0.99 in predicting and excluding EGF, respectively. The model also stratified long-term graft survival ( p <0.001), which ranged from 87% in the low-risk group to 60% in the high-risk group. In conclusion, based on a panel of donor and recipient variables, an artificial neural network can contribute to decision-making in ALDLT by predicting EGF risk.

Epidemiology, management, and burden of cytomegalovirus in solid organ transplant recipients in selected countries outside of Europe and North America: A systematic review.

BACKGROUND: Cytomegalovirus (CMV) is a frequent infectious complication following solid organ transplantation (SOT). Considering significant differences in healthcare systems, a systematic review was conducted to describe the epidemiology, management, and burden of CMV post-SOT in selected countries outside of Europe and North America. METHODS: MEDLINE, Embase, and Cochrane databases were searched for observational studies in SOT recipients across 15 countries in the regions of Asia, Pacific, and Latin America (search period: January 1, 2011 to September 17, 2021). Outcomes included incidence of CMV infection/disease, recurrence, risk factors, CMV-related mortality, treatment patterns and guidelines, refractory and/or resistant CMV, patient-reported outcomes, and economic burden. RESULTS: Of 2708 studies identified, 49 were eligible (n = 43/49; 87.8% in adults; n = 34/49, 69.4% in kidney recipients). Across studies, selection of CMV preventive strategy was based on CMV serostatus. Overall, rates of CMV infection (within 1 year) and CMV disease post-SOT were respectively, 10.3%-63.2% (9 studies) and 0%-19.0% (17 studies). Recurrence occurred in 35.4%-41.0% cases (3 studies) and up to 5.3% recipients died of CMV-associated causes (11 studies). Conventional treatments for CMV infection/disease included ganciclovir (GCV) or valganciclovir. Up to 4.4% patients were resistant to treatment (3 studies); no studies reported on refractory CMV. Treatment-related adverse events with GCV included neutropenia (2%-29%), anemia (13%-48%), leukopenia (11%-37%), and thrombocytopenia (13%-24%). Data on economic burden were scarce. CONCLUSION: Outside of North America and Europe, rates of CMV infection/disease post-SOT are highly variable and CMV recurrence is frequent. CMV resistance and treatment-associated adverse events, including myelosuppression, highlight unmet needs with conventional therapy.

Long-term outcome after living donor liver transplantation compared to donation after brain death in autoimmune liver diseases: Experience from the European Liver Transplant Registry.

Knowledge of living donor liver transplantation (LDLT) for autoimmune liver diseases (AILDs) is scarce. This study analyzed survival in LDLT recipients registered in the European Liver Transplant Registry with autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis (PSC) and the non-autoimmune disorder alcohol-related cirrhosis. In total, 29 902 individuals enrolled between 1998 and 2017 were analyzed, including 1003 with LDLT. Survival from >90 days after LDLT for AILDs in adults was 85.5%, 74.2%, and 58.0% after 5, 10, and 15 years. Adjusted for recipient age, sex, and liver transplantation era, adult PSC patients receiving LDLT showed increased mortality compared to donation after brain death (DBD) (hazard ratio [HR] = 1.95, 95% confidence interval [CI] = 1.36-2.80, p < .001). Pediatric PSC patients showed also increased mortality >90 days after LDLT compared to DBD (HR = 3.00, 95% CI 1.04-8.70, p = .043). Multivariate analysis identified several risk factors for death in adult PSC patients receiving LDLT including a male donor (HR = 2.49, p = .025). Adult PSC patients with LDLT versus DBD conferred increased mortality from disease recurrence (subdistribution hazard ratio [subHR] = 5.36, p = .001) and biliary complications (subHR = 4.40, p = .006) in multivariate analysis. While long-term outcome following LDLT for AILD is generally favorable, PSC patients with LDLT compared to DBD might be at increased risk of death.

Outcomes of right lobe donors with BMI≥30 for living donor liver transplantation.

BACKGROUND: Donor BMI above 30 is generally considered contraindication for donor hepatectomy. We compared the donor outcomes based on BMI threshold and weight loss. PATIENTS AND METHODS: All potential donors were identified and data were collected retrospectively. Steatosis was assessed based on liver-spleen Hounsfield unit difference and absolute liver intensity values. We compared BMI≥30 (n = 53) and BMI < 30 (n = 64) donor outcomes. Donors with weight loss (WL) prior to surgery were also analyzed separately. Complications were graded by Clavien-Dindo classification. RESULTS: All donors underwent open right donor hepatectomy. There was no difference between BMI≥30 and < 30 groups except female predominance in BMI≥30 group (P = .006). Both groups had similar rates of complication rates in all categories, similar remnant volume, operative time, length of stay and similar postoperative liver function recovery (all P > .05). On the other hand, donors with WL were more commonly male, had smaller graft size, and higher biliary complications rates compared to no-WL donors (all P < .05). Multivariate binary logistics regression analysis revealed no association between BMI or WL and outcomes. CONCLUSION: We demonstrate that donors with BMI≥30 have similar outcomes compared to BMI < 30 donors with our defined selection criterion, therefore BMI≥30 is not an absolute contraindication to donate right liver, provided that there is no significant steatosis and remnant liver is satisfactory. For potential overweight donors, WL down to BMI < 30 is a reasonable target. Higher biliary complication rates after WL should be investigated further.

Early removal of drains and lines after liver transplantation to reduce the length of hospital stay and enhance recovery - A systematic review of the literature and expert panel recommendations.

BACKGROUND: The timing of removing abdominal drains, central venous catheters (CVC), and urinary catheters (UC) on post liver transplantation (LT) outcomes is not well elucidated. OBJECTIVES: To provide international expert panel recommendations and guidelines on time of drain and catheter removal as a part of an ERAS protocol to reduce the length of hospital stay and enhance recovery. METHODS: Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. Papers considered were those reporting one or more outcomes of interest related to drainage and line removal in the setting of LT. POSPERO Protocol ID: CRD42021238349 RESULTS: On analyzing five relevant studies pertaining to drains in patients undergoing LT (four retrospectives and one prospective), the length of hospital and/or ICU stay was similar or shorter, and postoperative morbidity and mortality were lower in those without drains. No studies pertaining specifically to the time of removal of drains, CVC's, or UC's in LT were found. Studies in patients undergoing major abdominal surgery or hepatectomies recommend early removal of CVC and UC to reduce catheter-associated infections. CONCLUSIONS: Based more on expert recommendation, we propose that abdominal drains, if placed during LT, should be removed by postoperative day 5 after LT, based on quantity and fluid characteristics (Quality of Evidence; Low to Moderate | Grade of Recommendation; Strong). Larger studies are needed to more reliably determine indications for early drain and line removal in an ERAS protocol setting.

Multi-center living liver donor quality of life survey up to 20 years after donor hepatectomy and association with surgical outcomes.

BACKGROUND: We implemented a multicenter interview with the donors to investigate Quality of Life (QoL) up to 20 years following donation. METHODS: Data were collected retrospectively. Complications were graded by Dindo-Clavien classification. RESULTS: Median follow-up was 16.1 years. Out of 485 donors, 272 responded (56.1%). The majority (>90%) reported they are in excellent/good overall health and positive or no impact of donation on professional life. Length of stay (LOS) was associated with impact on professional life and return to baseline functionality (both p = 0.046). Major complication was not associated with current physical condition or return to baseline normalcy (p = 0.06). Seventy-five (27.5%) reported unsure or no to donate again. None of the parameters were associated with donation again response. Faster return to baseline functionality, and more positive impact on professional life were reported in the last decade, likely secondary to less complication rates (all p < 0.001). CONCLUSION: This the longest follow up reports after living liver donation among German and Turkish populations. Although subject to recall bias, LOS was associated with negative impact on professional life and return to baseline functionality. Regret feelings were higher than literature. These long-term effects should be incorporated into donor discussions.

Comparison of intraoperative biliary anastomosis stenting technique in living-donor liver transplantation: Review of 41 patients.

BACKGROUND: Biliary fistula is one of the most important complications in liver transplantation. Complications can vary from simple local peritonitis to death, and various techniques have been described to prevent them. In this study, we compared two different stenting methods used in biliary tract anastomosis in living-donor liver transplantation. METHODS: We retrospectively analyzed data from 41 living-donor liver transplantations that were performed due to endstage liver failure between August 2019 and November 2020. Patients were grouped according to the stenting technique used in biliary anastomosis. Postoperative biliary tract complications were investigated. RESULTS: Biliary fistulas were observed in 2 (7.4%) patients in the internal stent group, while 4 (28.5) fistulas were observed in the external stent group. Biliary tract stricture was observed in 2 (7.4%) patients in the internal stent group, but there was no statistical difference in complications. The preoperative MELD score (p = 0.038*) was found to be statistically significant in regard to developing complications. DISCUSSION: Our study did not show the effect of stenting methods used during biliary anastomosis on the development of complications. However, larger randomized controlled studies are needed.

A Review on the Concepts for Initially Unresectable Liver Tumors - Bridge to Surgery.

Surgical treatments of advanced tumors have expanded in the last two decades as a result of ad-vances in surgical techniques, advanced interventional radiology methods, improved intensive care unit settings and increased overall life expectancy. Advanced liver tumors represent a broad category from various malignancies such as liver metastasis or native liver tumors. Not uncom-monly these tumors are not amenable to curative treatment and require down-staging, or local control at the initial diagnosis. Herein we discuss the portal vein embolization (PVE), transarterial radioembolization (TARE) with Yttrium-90 (Y-90), and surgical options namely, two-staged hepatectomy (TSH), and associating liver partition and portal vein ligation for staged hepatecto-my (ALPPS) as bridging strategies for definitive surgical treatment.

Living Donor Liver Transplantation: The Optimal Curative Treatment for Hepatocellular Carcinoma Even Beyond Milan Criteria.

INTRODUCTION: Liver transplantation offers the most reasonable expectation for curative treatment for hepatocellular carcinoma. Living-donor liver transplantation represents a treatment option, even in patients with extended Milan criteria. This study aimed to evaluate the outcomes of hepatocellular carcinoma patients, particularly those extended Milan criteria. MATERIALS AND PATIENTS: All HCC patients who received liver transplant for HCC were included in this retrospective study. Clinical characteristics including perioperative data and survival data (graft and patient) were extracted from records. Univariate and multivariate analyses was performed to identify significant prognostic factors for survival, postoperative complications and recurrence. RESULTS: Two-hundred and two patients were included. The median age was 54.8 years (IQR 53-61). Fifty-one patients (25.3%) underwent deceased donors liver transplantation and 151 patients (74.7%) underwent living donor liver transplantation. Perioperative mortality rate was 5.9% (12 patients). Recurrent disease occurred in 43 patients (21.2%). The overall 1-year and 5-year survival rates were 90.7% and 75.6%, respectively. Significant differences between patients beyond Milan criteria compared to those within Milan criteria were not found. Alpha-fetoprotein level >300 ng/mL, vascular invasion, and bilobar tumor lesions were independent negative prognostic factors for survival. CONCLUSION: Liver transplantation is the preferred treatment for hepatocellular carcinoma and it has demonstrated an excellent potential to cure even in patients with beyond Milan criteria. This study shows that the Milan criteria alone are not sufficient to predict survival after transplantation. The independent parameters for survival prediction are Alpha-Fetoprotein-value and status of vascular invasion.

Liver transplantation for combined hepatocellular-cholangiocarcinoma: Outcomes and prognostic factors for mortality. A multicenter analysis.

INTRODUCTION: Combined hepatocellular-cholangiocarcinoma is rare and comprises features of hepatocellular carcinoma and cholangiocarcinoma. The treatment of choice has not yet been defined. The aim of the study was to analyze outcomes of patients with combined hepatocellular-cholangiocarcinoma, who underwent liver transplantation. MATERIAL AND METHODS: All patients with combined hepatocellular-cholangiocarcinoma, who underwent liver transplantation, from January 2001 to August 2018 were identified. Pre-, intra- and postoperative data were retrospectively assessed. A univariate analysis was performed to identify prognostic factors. RESULTS: A total number of 19 patients were included to this study. Perioperative death was seen in two patients (10.5%). Recurrent disease was reported in 11 patients (64.7%) within the median time of 4 months. One and three years survival rates were 57.1% (CI 0.301-1) and 38.1% (CI 0.137-1). Factors associated mortality were tumor size >3 cm, presence of lymphatic invasion, and prolonged ICU stay. Patients with mixed HCC-CC lesions have significantly better survival compared to patients with separate lesions of HCC and CCC in one liver (p = .025). CONCLUSION: Although overall survival rates are clearly decreased compared to HCC patients, liver transplantation should be taken under consideration for selected patients with early stage and real mixed HCC-CC, who are likely to benefit from liver transplantation.

Adult living donor liver transplantation from donors with Gilbert's syndrome: Is it safe?

BACKGROUNDS: We evaluate whether it is safe to accept donors with Gilbert's syndrome (GS) for a living donor liver transplantation (LDLT) or not. This study is the first controlled study to be conducted. METHODS: Between January 2004 and May 2014, 600 LDLTs which used right lobe liver grafts were performed in our center. Forty-five of the 600 donors had a GS diagnosis. For a control group, 99 donors without GS who had completed 1 year or more of follow-up were selected retrospectively and consecutively. The clinical results of the donors and recipients were then analyzed. RESULTS: A total of 45 donors with GS and 99 donors without GS were included. There were no significant differences in patient demographics, actual graft weight, remnant ratio, portal and ductal variations, pre-peri-post-operative liver enzymes. The donors with GS had significantly higher bilirubin levels compared with the control group at first reading, at maximal peak, and post-operative 1-7 days, 1st and 6th months (P < .001 for all readings). Post-operative complication ratio was 40% in GS, 34.3% in non-GS group. In GS and non-GS group, hospitalization period was 10.2 and 9.2 days, respectively. The 1-year donor survival rate was 100% for both groups and 1-year recipient survival was similar who have donors with GS and non-GS (93.3%; 92.9%, P = .93). CONCLUSIONS: The use of right lobe grafts from donors with GS appears to be safe for donor health.

The prognostic relationship between histopathological and immunohistochemical features of hepatocellular carcinoma, intrahepatic cholangiocarcinoma and mixed type.

Hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and combined hepatocellular and cholangiocarcinoma are the most common cancers of the liver. In this study, our first aim is to evaluate the relationship between prognosis and clinicopathological parameters. The second aim involves investigating the need for immunohistochemical staining and patterns of tumours to differentiate between them. Sixty-one cases were included in this study. For IHC, we used Hep par-1, CK7, CK19, CD56 and p53 staining, and the patterns of tumours were evaluated in haematoyxylin-eosin sections. No significant differences were found in Kaplan-Meier life analysis between the tumour types and OS and DFS values, but these values were greater in HCC than in ICC. There were no relationships between clinicopathologic parameters and OS and DFS. Although the multifocality, stage and grade of tumour were higher in HCC than in ICC, the perineural invasion and lymph node metastasis were more common in ICC than in HCC. The diagnosis was changed in 4 cases, from HCC to ICC in one case and to combined type in 3 cases after IHC. Pathologist should be alert to mixed patterns in terms of diagnosis and IHC, because it helps differential diagnosis in these cases.

Outcomes of liver transplantation for non-alcoholic steatohepatitis: A European Liver Transplant Registry study.

BACKGROUND & AIMS: Little is known about outcomes of liver transplantation for patients with non-alcoholic steatohepatitis (NASH). We aimed to determine the frequency and outcomes of liver transplantation for patients with NASH in Europe and identify prognostic factors. METHODS: We analysed data from patients transplanted for end-stage liver disease between January 2002 and December 2016 using the European Liver Transplant Registry database. We compared data between patients with NASH versus other aetiologies. The principle endpoints were patient and overall allograft survival. RESULTS: Among 68,950 adults undergoing first liver transplantation, 4.0% were transplanted for NASH - an increase from 1.2% in 2002 to 8.4% in 2016. A greater proportion of patients transplanted for NASH (39.1%) had hepatocellular carcinoma (HCC) than non-NASH patients (28.9%, p <0.001). NASH was not significantly associated with survival of patients (hazard ratio [HR] 1.02, p = 0.713) or grafts (HR 0.99; p = 0.815) after accounting for available recipient and donor variables. Infection (24.0%) and cardio/cerebrovascular complications (5.3%) were the commonest causes of death in patients with NASH without HCC. Increasing recipient age (61-65 years: HR 2.07, p <0.001; >65: HR 1.72, p = 0.017), elevated model for end-stage liver disease score (>23: HR 1.48, p = 0.048) and low (<18.5 kg/m2: HR 4.29, p = 0.048) or high (>40 kg/m2: HR 1.96, p = 0.012) recipient body mass index independently predicted death in patients transplanted for NASH without HCC. Data must be interpreted in the context of absent recognised confounders, such as pre-morbid metabolic risk factors. CONCLUSIONS: The number and proportion of liver transplants performed for NASH in Europe has increased from 2002 through 2016. HCC was more common in patients transplanted with NASH. Survival of patients and grafts in patients with NASH is comparable to that of other disease indications. LAY SUMMARY: The prevalence of non-alcoholic fatty liver disease has increased dramatically in parallel with the worldwide increase in obesity and diabetes. Its progressive form, non-alcoholic steatohepatitis, is a growing indication for liver transplantation in Europe, with good overall outcomes reported. However, careful risk factor assessment is required to maintain favourable post-transplant outcomes in patients with non-alcoholic steatohepatitis.

C-Reactive Protein and Platelet-Lymphocyte Ratio as Potential Tumor Markers in Low-Alpha-Fetoprotein Hepatocellular Carcinoma.

The hepatocellular carcinoma (HCC) tumor marker alpha-fetoprotein (AFP) is only elevated in about half of the HCC patients, limiting its usefulness in following the effects of therapy or screening. New markers are needed. It has been previously noted that the inflammation markers C-reactive protein (CRP) and platelet-lymphocyte ratio (PLR) are prognostically important and may reflect HCC aggressiveness. We therefore examined these 2 markers in a low-AFP HCC cohort and found that for HCCs > 2 cm, both markers significantly rise with an increasing maximum tumor diameter (MTD). We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Youden index value for each marker, and their area-under-the-curve values for each MTD group. Patients were dichotomized into 2 groups based on the CRP and PLR from the receiver-operating characteristic curve analysis. In the logistic regression models of the 4 different MTD patient groups, CRP and PLR levels were statistically significant to estimate MTD in univariate logistic regression models of MTD groups > 2 cm. CRP and PLR were then combined, and the combination was statistically significant to estimate MTD groups of 3-, 4-, and 5-cm cutoffs. CRP and PLR thus have potential as tumor markers for low-AFP HCC patients, and possibly for screening.

Living Donor Liver Transplantation.

In 50 years after the first liver transplantation, the medical world has witnessed the liver transplantation to become one of the widely recognized and leading branches of surgery. In this period, liver transplantation combined with surgical technique, patient selection, advancements in anesthesia and postoperative care and increased experience has become the most effective treatment option in treatment of several acute and chronic liver diseases. Yet, the worldwide organ restriction and associated high mortality rates in organ transplantation waiting list has compelled referring to living donors in order to expand the donor pool. This paper explains liver transplantation indications from living donors, the surgical technique involved, the complications of the procedure and the medical treatments used.

Graft-to-recipient weight ratio threshold adjusted to the model for end-stage liver disease score for living donor liver transplantation.

The graft-to-recipient weight ratio (GRWR) is an important selection criterion for living donor liver transplantation (LDLT). The generally accepted threshold is known to be 0.8%. We believe that this threshold can be reduced under certain conditions. The aim of this study was to evaluate the results of these patients with GRWR < 0.8%. Between 2004 and 2015, 649 patients underwent right lobe LDLT for end-stage liver disease in adult patients. All recipients who had GRWR < 0.8% were identified. The data of these patients were retrospectively analyzed and compared to patients with GRWR ≥ 0.8%. There were 43 patients with GRWR < 0.8%. Out of these patients, 7 (16%) had GRWR of 0.6%. The median Model for End-Stage Liver Disease (MELD) score was 15, and the median donor age was 30 years. Anterior segment drainage was ensured. Portal inflow modulation was performed by splenic artery ligation according to the portal flow. Postoperative complications were seen in 6 (14%) patients. Of all 43 patients, 3 (7%) died perioperatively within 1 month, and 1 (2%) patient underwent retransplantation due to graft failure. The mean hospital stay was 18 days. The 1-year survival rate was 93%. None of the patients had a laboratory MELD score above 20. The comparison of the results with the patients who had GRWR ≥ 0.8% has shown no significant difference, except MELD score, body mass index (BMI), and rate of anterior segment drainage. The GRWR can be decreased even to 0.6% if the MELD score is below 20, donor age is below 45 years, and there are no signs for any hepatosteatosis of the donor graft. In these patients, it is essential that the anterior segment drainage is secured and the portal inflow modulation is performed according to the portal flow.

The long-term efficacy of combining nucleos(t)ide analog and low-dose hepatitis B immunoglobulin on post-transplant hepatitis B virus recurrence.

BACKGROUND: The aim of this study was to determine the long-term efficacy of nucleos(t)ide analog (NA) and low-dose hepatitis B immunoglobulin (HBIG) combination treatment for preventing post-transplant hepatitis B virus (HBV) recurrence. METHODS: A total of 296 patients with HBV-associated liver disease who underwent liver transplantation (LT) were enrolled. A combination of a daily NA and low-dose HBIG was used after LT. RESULTS: The median follow-up period was 46 months. HBV recurrence occurred in eight patients. The cumulative probability of HBV recurrence at 1, 3, 5, and 7 years was 1%, 3%, 3%, and 4%, respectively. Seven were on lamivudine (LMV) or adefovir dipivoxil (ADV), or LMV and ADV and HBIG combination treatment and one entecavir (ETV) and HBIG. With Cox regression analysis, HBV recurrence was determined to be associated with the presence of hepatocellular cancer (HCC) prior to LT (HR: 12.3, P=.02). Overall, 44 patients died. Survival was significantly better in the ETV or tenofovir disoproxil fumarate (TDF) and HBIG group than the other group (P<.001). CONCLUSION: The combination of ETV or TDF and low-dose HBIG achieved a more favorable prophylaxis against HBV recurrence after LT. The presence of HCC prior to LT was associated with post-transplant HBV recurrence.

Liver transplantation for homozygote familial hypercholesterolemia: the only curative treatment.

FH is an autosomal dominant genetic disorder characterized by increased TC and LDL level, which leads to xanthomas, atherosclerosis, and cardiac complications even in childhood. The treatment options are diet, medical treatment, lipid apheresis, and LT. The aim of our study was to analyze our data of patients with FH. Between 2004 and 2015, there were 51 patients who underwent pediatric LT at our center. All patients with FH were identified, and the data were retrospectively analyzed. There were eight patients with homozygous FH in the median age of 10 years (IQR 6-12) who underwent LT. The median pre-operative TC and LDL levels were 611 mg/dL (IQR: 460-844) and 574 mg/dL (IQR: 398-728) and decreased to normal levels 1 week after LT (TC: 193 mg/dL and LDL: 141 mg/dL). Two patients died two and 18 months after LT due to sudden cardiac arrest. Both patients were diagnosed with cardiovascular disease pre-operatively. The LT is the only curative treatment for this disease. To achieve an excellent outcome, it should be performed before the development of cardiovascular disease, because the regression of severe cardiovascular disease after transplantation is limited.
