RESUMO
Autoimmune hepatitis (AIH) may recur after liver transplantation (LT). The aims of this study were to evaluate the incidence and risk factors for recurrent autoimmune hepatitis (rAIH). A multicenter retrospective French nationwide study, including all patients aged ≥16 transplanted for AIH, with at least 1 liver biopsy 1 year after LT, was conducted between 1985 and 2018. Risk factors for rAIH were identified using a multivariate Cox regression model. Three hundred and forty-four patients were included (78.8% women) with a median age at LT of 43.6 years. Seventy-six patients (22.1%) developed recurrence in a median time of 53.6 months (IQR, 14.1-93.2). Actuarial risk for developing rAIH was 41.3% 20 years after LT. In multivariate analysis, the strongest risk factor for rAIH was cytomegalovirus D+/R- mismatch status (HR=2.0; 95% CI: 1.1-3.6; p =0.03), followed by associated autoimmune condition. Twenty-one patients (27.6% of rAIH patients) developed liver graft cirrhosis after rAIH. Independent risk factors for these severe forms of rAIH were young age at LT, IgG levels >20.7 g/L, and LT in the context of (sub)fulminant hepatitis. Immunosuppression, especially long-term maintenance of corticosteroid therapy, was not significantly associated with rAIH. Recurrence of AIH after LT is frequent and may lead to graft loss. Recurrence is more frequent in young patients with active disease at the time of LT, yet systematic corticosteroid therapy does not prevent it.

BACKGROUND & AIMS: If alcohol-related liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) are now the two main indications for liver transplantation (LT), it has been recognized that both conditions can coexist in varying degrees and the concept of dual-aetiology fatty liver disease (DAFLD) has been proposed. This retrospective study aimed to evaluate, in a cohort of patients transplanted for ALD and NAFLD, the prevalence of DAFLD before LT and the impact on liver graft outcome. METHODS: From 1990 to 2010, all patients who underwent LT for the so-called ALD or NAFLD in our centre were included. Before LT, DAFLD was defined as patients with a history of excessive alcohol consumption and obesity associated with either diabetes or hypertension. Before LT, patients were separated into three groups: DAFLD, ALD, and NAFLD. Fatty liver graft disease was classified according to the FLIP algorithm. RESULTS: Out of 907, adult LT recipients were identified: 33 DAFLD patients, 333 ALD patients, and 24 NAFLD patients. After LT, ALD patients experienced significantly more alcohol relapse than DAFLD patients, who had twice more post-LT metabolic syndrome. Out of 926, post-LT biopsies, DAFLD patients had significantly more fatty liver graft disease due to metabolic syndrome features than ALD patients. CONCLUSION: Our results support that DAFLD recently emerged as an indication of LT. In the future, this particular population needs to be identified as a specific entity since post-LT outcome on the graft is different from ALD and more similar to NAFLD patients.

BACKGROUND: Wilson's disease (WD) is usually diagnosed in children and young adults; limited data exist on late-onset forms. OBJECTIVE: The aim was to characterize the clinical and paraclinical presentations, therapeutic management, and outcomes in patients with late-onset WD. METHODS: Patients diagnosed with WD after age 40 years were identified from the French Wilson's Disease Registry (FWDR). Clinical, laboratory, and imaging findings and treatment were reported at diagnosis and last follow-up. RESULTS: Forty-five patients were identified (median age: 49, range: 40-64) and placed in three groups according to their clinical presentation: neurological (n = 20, median diagnostic delay: 20 months), hepatic (n = 13, diagnostic delay: 12 months), and family screening (n = 12), all confirmed genetically. Six neurological patients had an atypical presentation (1 torticollis, 2 writer's cramps, 2 functional movement disorders, and 1 isolated dysarthria), without T2/fluid-attenuated inversion recovery brain magnetic resonance imaging (MRI) hyperintensities; 5 of 6 had no Kayser-Fleischer ring (KFR); 5 of 6 had liver involvement. In the neurological group, 84% of patients improved clinically, and 1 developed copper deficiency. In the hepatic group, 77% had cirrhosis; 6 patients required liver transplantation. In the screened group, 43% had mild liver involvement; 3 were not treated and remained stable; 24-h urinary copper excretion was normal in 33% of patients at diagnosis. CONCLUSIONS: In the FWDR, late-onset forms of WD affect 8% of patients, mostly with neurological presentations. Thirty percent of the neurological forms were atypical (isolated long-lasting symptoms, inconspicuous brain MRI, no KFR). With personalized treatment, prognosis was good. This study emphasized that WD should be suspected at any age and even in cases of atypical presentation. © 2022 The Authors.

BACKGROUND AND AIMS: Autoimmune hepatitis (AIH) is a rare indication (<5%) for liver transplantation (LT). The aim of this study was to describe the early outcome after LT for AIH. METHODS: A multicenter retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Occurrences of biliary and vascular complications, rejection, sepsis, retransplantation and death were collected during the first year after LT. RESULTS: A total of 344 patients (78.8% of women, 17.0% of (sub)fulminant hepatitis and 19.2% of chronic liver diseases transplanted in the context of acute-on-chronic liver failure [ACLF]) were included, with a median age at LT of 43.6 years. Acute rejection, sepsis, biliary and vascular complications occurred in respectively 23.5%, 44.2%, 25.3% and 17.4% of patients during the first year after LT. One-year graft and patient survivals were 84.3% and 88.0% respectively. The main cause of early death was sepsis. Pre-LT immunosuppression was not associated with an increased risk for early infections or surgical complications. Significant risk factors for septic events were LT in the context of (sub)fulminant hepatitis or ACLF, acute kidney injury at the time of LT (AKI) and occurrence of biliary complications after LT. AKI was the only independent factor associated with graft (HR = 2.5; 95% CI: 1.1-5.4; p = .02) and patient survivals (HR = 2.6; 95% CI: 1.0-6.5; p = .04). CONCLUSION: Early prognosis is good after LT for AIH and is not impacted by pre-LT immunosuppression but by the presence of AKI at the time of LT.

BACKGROUND & AIMS: Autoimmune hepatitis (AIH) is a rare indication for liver transplantation (LT). The aims of this study were to evaluate long-term survival after LT for AIH and prognostic factors, especially the impact of recurrent AIH (rAIH). METHODS: A multicentre retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Early deaths and retransplantations (≤6 months) were excluded. RESULTS: The study population consisted of 301 patients transplanted from 1987 to 2018. Median age at LT was 43 years (IQR, 29.4-53.8). Median follow-up was 87.0 months (IQR, 43.5-168.0). Seventy-four patients (24.6%) developed rAIH. Graft survival was 91%, 79%, 65% at 1, 10 and 20 years respectively. Patient survival was 94%, 84% and 74% at 1, 10 and 20 years respectively. From multivariate Cox regression, factors significantly associated with poorer patient survival were patient age ≥58 years (HR = 2.9; 95% CI, 1.4-6.2; p = 0.005) and occurrence of an infectious episode within the first year after LT (HR = 2.5; 95% CI, 1.2-5.1; p = 0.018). Risk factors for impaired graft survival were: occurrence of rAIH (HR = 2.7; 95% CI, 1.5-5.0; p = 0.001), chronic rejection (HR = 2.9; 95% CI, 1.4-6.1; p = 0.005), biliary (HR = 2.0; 95% CI, 1.2-3.4; p = 0.009), vascular (HR = 1.8; 95% CI, 1.0-3.1; p = 0.044) and early septic (HR = 2.1; 95% CI, 1.2-3.5; p = 0.006) complications. CONCLUSION: Our results confirm that survival after LT for AIH is excellent. Disease recurrence and chronic rejection reduce graft survival. The occurrence of an infectious complication during the first year post-LT identifies at-risk patients for graft loss and death.

BACKGROUND: Malignancies are a major cause of late death after liver transplantation (LT). In LT recipients presenting a malignancy, antineoplastic chemotherapy is central part of the therapeutic arsenal, but management of both immunosuppressive and antineoplastic chemotherapy can be very challenging. The aim of the present retrospective study was to describe a recent single center cohort of LT recipients treated with antineoplastic cytotoxic chemotherapy. METHODS: All LT recipients who received antineoplastic chemotherapy in our center between 2005 and 2021 were included. RESULTS: The study population included 72 antineoplastic chemotherapy courses in 69 patients. There was a majority of men (81.9%); median age at LT was 54.9 (range 1-68) and was 63.0 (18-79) at the diagnosis of malignancy. Lung carcinomas (23.6%), head and neck carcinomas (20.8%), lymphomas (16.7%), and recurrent hepatocellular carcinoma (HCC) (8.3%) were the most frequent malignancies. Neoadjuvant (30.6%), adjuvant (12.5%) or palliative (54.2%) chemotherapy was performed. Immunosuppressive regimen was modified from a calcineurin inhibitor (CNI)-based to an everolimus-based regimen (63.5% of CNI discontinuation). Median survival after diagnosis of malignancy was 22.5 months and 5-year survival was 30.1%. Chemotherapy regimen was considered optimal in 81.9% of the cases. Multivariate analysis disclosed that non-PTLD N+ stage malignancy (HR = 5.52 95%CI [1.40;21.69], p = .014), non-PTLD M+ stage malignancy (HR = 10.55 95%CI [3.20;34.73], p = .0001), and suboptimal chemotherapy (HR = 2.73 95%CI [1.34;5.56], p = .005) were significantly associated with poorer prognosis. No rejection episode occurred during chemotherapy. CONCLUSIONS: The present study is the first one focused on antineoplastic chemotherapy in LT recipients. Our results suggest that immunosuppressive drugs and antineoplastic chemotherapy can be managed satisfactorily in most cases but this needs confirmation from larger cohorts.

OBJECTIVE: Liver stiffness measurement (LSM) is a tool used to screen for significant fibrosis and portal hypertension. The aim of this retrospective multicentre study was to develop an easy tool using LSM for clinical outcomes in advanced chronic liver disease (ACLD) patients. DESIGN: This international multicentre cohort study included a derivation ACLD patient cohort with valid two-dimensional shear wave elastography (2D-SWE) results. Clinical and laboratory parameters at baseline and during follow-up were recorded. LSM by transient elastography (TE) was also recorded if available. The primary outcome was overall mortality. The secondary outcome was the development of first/further decompensation. RESULTS: After screening 2148 patients (16 centres), 1827 patients (55 years, 62.4% men) were included in the 2D-SWE cohort, with median liver SWE (L-SWE) 11.8 kPa and a model for end stage liver disease (MELD) score of 8. Combination of MELD score and L-SWE predict independently of mortality (AUC 0.8). L-SWE cut-off at ≥20 kPa combined with MELD ≥10 could stratify the risk of mortality and first/further decompensation in ACLD patients. The 2-year mortality and decompensation rates were 36.9% and 61.8%, respectively, in the 305 (18.3%) high-risk patients (with L-SWE ≥20 kPa and MELD ≥10), while in the 944 (56.6%) low-risk patients, these were 1.1% and 3.5%, respectively. Importantly, this M10LS20 algorithm was validated by TE-based LSM and in an additional cohort of 119 patients with valid point shear SWE-LSM. CONCLUSION: The M10LS20 algorithm allows risk stratification of patients with ACLD. Patients with L-SWE ≥20 kPa and MELD ≥10 should be followed closely and receive intensified care, while patients with low risk may be managed at longer intervals.

OBJECTIVES: Determining 24-hour urinary copper excretion (UCE) levels is useful for diagnosing Wilson's disease (WD) and for treatment monitoring. Exchangeable copper (ExC) is a novel potential marker, but its long-term changes have never been described in patients under chelation therapy. Our aim was to describe the long-term changes in ExC levels compared to UCE levels in symptomatic WD pediatric patients under chelation therapy. METHODS: A retrospective, descriptive, and analytical study including all patients under 18 years of age, diagnosed between 2006 and 2020, and treated with chelation therapy was conducted at the National Reference Center for WD in Lyon. Ceruloplasmin levels, serum copper, 24 h-UCE, ExC, and liver enzymes at diagnosis and during follow-up were analyzed. RESULTS: Our study included 36 patients, predominantly with hepatic form of WD (n = 31). The median [interquartile range (IQR)] age at diagnosis was 10.5 (8.4-13.1) years, and the median (IQR) follow-up duration was 6.3 (3.3-8.8) years. At diagnosis, the median (IQR) ExC value was 1.01 (0.60-1.52) µmol/L. There was a significant decrease during the first year of chelation treatment ( P = 0.0008), then a stabilization. The median (IQR) ExC values was 0.38 (0.22-0.63) µmol/L at 12-18 months and 0.43 (0.31-0.54) µmol/L at 5 years of chelation treatment ( P = 0.4057). Similarly, there was a significant decrease in 24-hour UCE ( P < 0.001) during the first year of chelation treatment, then a stabilization. CONCLUSIONS: Our study showed a significant decrease in ExC and 24-hour UCE levels during the first year of follow-up; The dynamics of both biomarkers were similar along the follow-up, demonstrating their usefulness in clinical practice for monitoring WD.

OBJECTIVES: To describe a cohort of Wilson disease (WD) pediatric cases, and to point out the diagnostic particularities of this age group and the long-term outcome. METHODS: Clinical data of 182 pediatric patients included in the French WD national registry from 01/03/1995 to 01/06/2019 were gathered. RESULTS: Diagnosis of WD was made at a mean age of 10.7â±â4.2âyears (range 1-18âyears). At diagnosis, 154 patients (84.6%) had hepatic manifestations, 19 (10.4%) had neurological manifestations, and 9 patients (4.9%) were asymptomatic. The p.His1069Gln mutation was the most frequently encountered (14% of patients).Neurological patients were diagnosed at least 1 year after they presented their first symptoms. At diagnosis, the median urinary copper excretion (UCE) was 4.2âµmol/24âhours (0.2-253). The first-line treatment was d-penicillamine (DP) for 131 (72%) patients, zinc salts for 24 (13%) patients, and Trientine for 17 (9%) patients. Liver transplantation was performed in 39 (21.4%) patients, for hepatic indications in 33 of 39 patients or for neurological deterioration in 6 of 39 patients, mean Unified Wilson's Disease Rating Scale of the latter went from 90â±â23.1 before liver transplantation (LT) to 26.8â±â14.1 (Pâ<â0.01) after a mean follow-up of 4.3â±â2.5âyears. Overall survival rate at 20âyears of follow-up was 98%, patient and transplant-free combined survival was 84% at 20âyears. CONCLUSION: Diagnosis of WD can be challenging in children, particularly at the early stages of liver disease and in case of neurological presentation; hence the support of clinical scores and genetic testing is essential. Diagnosis at early stages and proper treatment ensure excellent outcomes, subject to good long-term treatment compliance. LT is a valid option for end-stage liver disease not responding to treatment and can be discussed for selected cases of neurological deterioration.

INTRODUCTION: Different treatments exist for Zenker diverticulum. We compared flexible endoscopic myotomy of the cricopharyngeal muscle, using a technique called the "window technique" in order to improve the field of view, to surgical approaches. MATERIALS AND METHODS: Patients were retrospectively included and divided into a gastrointestinal group, with flexible endoscopic myotomy, and an ear-nose-throat treatments group with either rigid endoscopic treatment, either cervicotomy. We evaluated effectiveness in terms of quality of life (on a scale on 0 to 10) safety and technical aspects of each procedure. RESULTS: A total 106 patients who underwent 128 interventions were included. Rigid endoscopic procedures were the shortest (p < 0.001), with no difference for adverse event. Endoscopic approaches, flexible and rigid ones, were associated with shorter time to intake resumption (1 and 3 days, respectively, vs 6 after cervicotomy) and shorter length of hospital stay (3 and 4 days, respectively, vs 7 after cervicotomy) (p = 0.001). Post-operative QoL was better after flexible endoscopy (9/10) and open cervicotomy (9/10) than after rigid endoscopy (7/10) (p = 0.004). Patients declared fewer residual symptoms after open cervicotomy (77% of low symptomatic patients) and flexible endoscopy (80%) than after rigid endoscopy (43%) (p = 0.003). Conversion to open surgery was more frequent during rigid than flexible endoscopies (18% vs 0%, p = 0.0008). CONCLUSION: Flexible endoscopic approach of Zenker diverticulum treatment seems to be safe and effective and may be an alternative to surgical approaches. Myotomy can be eventually helped by the window technique.

Longterm use of a calcineurin inhibitor (CNI)-based regimen is one of the major reasons for chronic renal failure in liver transplantation recipients (LTRs). The Everolimus Liver registry (EVEROLIVER) evaluated renal function in LTRs who were converted to everolimus (EVR). This observational registry included all LTRs receiving EVR across 9 centers from France. Data are being collected in an electronic database over 10 years (12 visits/patient) to evaluate efficacy, renal function (estimated glomerular filtration rate [eGFR]), and safety of EVR use in clinical practice, and the current analysis is reporting up to 60 months of findings. Until September 2017, 1045 patients received EVR after a mean time of 3.6 ± 5.1 years. CNI withdrawal was feasible in 57.7% of patients as of month 60. Mean eGFR improved in patients with baseline eGFR <60 mL/minute/1.73 m2 and was maintained in those with baseline eGFR ≥60 mL/minute/1.73 m2 . Among patients with chronic kidney disease (CKD; baseline eGFR <60 mL/minute/1.73 m2 ), 55% converted to EVR within 3 months (early conversion) and 39.4% converted between 4 and 12 months after transplantation (mid-conversion) experienced improvement in eGFR (≥60 mL/minute/1.73 m2 ) at month 36. Only 20.9% and 17.4% among those converted beyond 12 months (late conversion) experienced improvement respectively at month 36 and 60. A logistic regression analysis in patients with CKD stage ≥3 demonstrated that late conversion, age, and female sex were associated with nonimprovement of eGFR (≥60 mL/minute/1.73 m2 ). Data from this real-life use of EVR indicate that renal function was maintained from the preconversion period until month 36 even in patients with advanced CKD. However, early rather than late conversion appears to be a safe approach to preserve longterm renal function in LTRs.

Alcohol-related liver disease (ALD) is one of the main indications for liver transplantation (LT). Severe alcohol relapse can rapidly lead to recurrent alcohol-related cirrhosis (RAC) for the graft. The aim of this study was to describe the natural history of RAC and the overall survival after LT and after an RAC diagnosis. From 1992 to 2012, 812 patients underwent primary LT for ALD in 5 French transplant centers. All patients with severe alcohol relapse and an RAC diagnosis on the graft were included. The diagnosis of cirrhosis was based on the analysis of liver biopsy or on the association of clinical, biological, radiological, and/or endoscopic features of cirrhosis. RAC was diagnosed in 57/162 patients (35.2%) with severe alcohol relapse, and 31 (54.4%) of those patients had at least 1 episode of liver decompensation. The main types of decompensation were ascites (70.9%), jaundice (58.0%), and hepatic encephalopathy (9.6%). The cumulative probability of decompensation was 23.8% at 5 years, 50.1% at 10 years, and 69.9% at 15 years after LT. During the follow-up, 36 (63.2%) patients died, the main cause of death being liver failure (61.1%). After diagnosis of cirrhosis, the survival rate was 66.3% at 1 year, 37.8% at 5 years, and 20.6% at 10 years. In conclusion, RAC is associated with a high risk of liver decompensation and a poor prognosis. Prevention of severe alcohol relapse after LT is a major goal to improve patient survival.

Liver transplantation (LT) has been proposed as a curative treatment in hereditary hemorrhagic telangiectasia (HHT) with severe hepatic involvement. We provide a long-term evaluation of graft status after LT for HHT, with a focus on the risk of recurrence. The present study included all patients prospectively followed up after LT for HHT in the Lyon Liver Transplant Unit from 1993 to 2010, with a survival of more than 1 year. Protocol clinical, radiological, and histological examinations were performed at regular intervals. Fourteen patients were included (13 women and one man). Median age at LT was 52.5 years (range: 33.1-66.7). In eight patients (seven female), disease recurrence was diagnosed by abnormal radiological features, suggestive of microcirculatory disturbances. Typical vascular lesions, including telangiectasia, were demonstrated by liver biopsy in five of these patients. The median interval between LT and diagnosis of recurrence was 127 months (range: 74-184). The risk of recurrence increased over time; estimated cumulative risk was 47.9% at 15 years. Liver tissue analysis found the coexistence of an angiogenic process combined with endothelial microchimerism, as shown by the presence of vascular lining cells of recipient origin. Conclusion: The present data show that disease recurrence occurs, usually after a long delay, in a significant number of patients treated by LT for liver complications of HHT. This strongly supports the necessity of a lifelong follow-up and suggests that therapeutic strategy needs discussion and evaluation, especially of the role of potential adjuvant treatments to LT, such as antiangiogenic medications, when recurrent disease appears.

BACKGROUND: Endoscopic resection has developed over the years. The main complications are perforation and bleeding. This study aimed to evaluate safety and effectiveness of digestive endoscopic resection in patients with cirrhosis. METHODS: This retrospective, open-label, single-center study included all consecutive patients with cirrhosis who were admitted for endoscopic resection between 2009 and 2016. Safety, efficacy, and risk factors for delayed bleeding were analyzed. RESULTS: 126 patients undergoing 164 procedures were included: 65 endoscopic resections (49 patients) in the upper gastrointestinal tract (esophagus 34, stomach 20, duodenum 11) and 99 in the lower gastrointestinal tract (77 patients). Mean Model for End-Stage Liver Disease score was 9.9 (standard deviation 4.5). Esophageal varices were present in 50 patients, and 21 patients had decompensated cirrhosis. The overall curative rate of endoscopic resection was 84.0â%. No patients died during 30-day follow-up. Immediate overall morbidity was 6.1â%, with two postoperative fevers and eight bleeds. Risk factors for delayed bleeding were duodenal location (Pâ<â0.01), antiplatelet medication (Pâ=â0.02), and lower glomerular filtration rate (GFR) (Pâ=â0.01) in univariate analysis. Duodenal location and lower GFR remained statistically significant in multivariate analysis, with respective odds ratios for bleeding of 52.12 and 1.04. No liver decompensation occurred after endoscopic resection. CONCLUSIONS: Endoscopic resection was safe and effective in patients with mild (Childâ-âPugh class A/B) cirrhosis, and should be proposed as a first option for treatment of superficial neoplasia. Additional data in patients with severe cirrhosis are needed to confirm the safety in this population.

The incidence and impact of anti-human leukocyte antigen donor-specific alloantibodies (DSAs) developing after liver transplantation (LT) remains controversial and not extensively studied. The aim of the present study was to assess the incidence of DSAs, to identify risk factors for the development of DSAs, and to understand the impact of DSAs in a large population of adult LT recipients. This single-center retrospective study included all adult patients who underwent a first LT between 2000 and 2010 in our center. The study population mainly consisted of male patients, the mean age was 52.4 years, and the main indication was alcoholic cirrhosis (54.1%). From the 297 patients included in the cross-sectional study, 14 (4.7%) had preformed DSAs, and 59 (19.9%) presented de novo DSAs (12.2% at 1 year, 13.4% at 5 years, and 19.5% at 10 years). Multivariate analysis found that female donor sex (hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.12-2.01; P = 0.01) and delay between LT and DSA screening (HR, 1.10; 95% CI, 1.01-1.20; P = 0.03) were associated with occurrence of de novo DSAs. From the 190 patients included in the subgroup longitudinal analysis, exposure to tacrolimus (mean trough level during the periods 0-2 years and 0-3 years) was significantly lower for patients having DSAs at 5 years. Concerning histology, only acute rejection (P = 0.04) and portal fibrosis ≥2 (P = 0.02) were more frequent at 1 year for patients with DSAs. Patient survival and graft survival were not significantly different according to the presence or not of DSAs at 1 year. Among the 44 patients who had de novo or persistent preformed DSAs, the diagnosis of antibody-mediated rejection was made in 4 (9.1%) patients after 1, 47, 61, and 74 months following LT. In conclusion, the results of the present study suggest that DSAs are observed in a minority of LT adult patients, with limited overall impact on graft and patient outcome.

Patients having received a liver transplantation (LT) for alcoholic liver disease (ALD) have a high risk of de novo malignancies, especially in the upper aerodigestive tract and lungs due to their smoking and alcohol history. The aim of this retrospective study was to compare a group of patients transplanted for ALD who continue to smoke and who were included in an intensive screening program for tobacco-related cancers implemented at the Grenoble University Hospital and a group of similar patients followed according to usual practice (chest computed tomography [CT] scan every 5 years) at the Edouard Herriot Hospital in Lyon. The intensive screening program consisted of an annual checkup, including a clinical examination by an otorhinolaryngologist, a chest CT scan, and an upper digestive endoscopy. A total of 147 patients were included: 71 patients in Grenoble and 76 patients in Lyon. The cumulative incidence of a first tobacco-related cancer was 12.3% at 3 years, 20.6% at 5 years, 42.6% at 10 years, and 64.0% at 15 years. A curative treatment was possible in 80.0% of the patients in Grenoble versus 57.9% in Lyon (P = 0.068). The rates of curative treatment were 63.6% versus 26.3% (P = 0.062) for lung cancers, 100.0% versus 87.5% (P = 0.498) for lip-mouth-pharynx and larynx cancers, and 66.7% versus 100.0% (P = 1) for esophageal cancers, respectively. In addition, for lung cancers, regardless of study group, 68.7% received a curative treatment when the diagnosis was made by CT scan screening versus 14.3% when it was made because of symptoms (P = 0.008). In conclusion, our study strongly confirms the high rate of tobacco-related de novo malignancies in LT patients for ALD and suggests that the screening of lung cancer by annual chest CT scan could significantly increase the rate of curative treatment.

BACKGROUND & AIMS: Measuring of the relative exchangeable copper seems to be a promising tool for the diagnosis of Wilson disease. The aim of our study is to determine the performance of REC for the diagnosis of Wilson disease in a population of patients with chronic liver diseases. METHODS: Measuring of exchangeable serum copper levels and relative exchangeable copper was performed in a group of Wilson disease patients at diagnosis or at clinical deterioration because of non-compliance (group 1, n=9), a group of stable WD patients (group 2, n=40), and two groups of patients (adult and paediatric) followed for non-Wilsonian liver diseases (group 3, n=103 and group 4, n=49 respectively). RESULTS: Exchangeable serum copper (N: 0.6-1.1 µmol/L) was significantly higher in group 1 (mean 2.2±0.7 µmol/L) compared to the other three groups: group 2=0.9±0.4 µmol/L, group 3=1.2±0.4 µmol/L, group 4=1.1±0.3 µmol/L (P<0.05). Relative exchangeable copper was significantly higher in Wilson disease patients group 1 and 2 (mean 52.6% and 43.8%) compared to patients suffering from other liver diseases (mean 7.1% and 5.9%) (P<0.05). CONCLUSIONS: Our study confirms that the determination of relative exchangeable copper is a highly valuable tool for the diagnosis of Wilson disease.

BACKGROUND: Nonmelanoma skin cancers (NMSCs) are the most frequent cancers in solid organ transplant recipients, with a high rate of subsequent tumors. OBJECTIVES: To describe subsequent NMSCs in a large cohort of liver transplant recipients (LTRs) with long follow-up and analyze the factors influencing it, including immunosuppressive regimen. METHODS: A total of 96 LTRs (76 male) with a personal post-transplant history of squamous cell carcinoma, basal cell carcinoma or Bowen's disease were included, with a median follow-up of 12.4 years (range, 1.5-27.8) after liver transplantation. RESULTS: The median follow-up after first NMSC was 6.4 years (range, 0.17-22.1). In all, 52 patients (53.1%) developed 141 subsequent NMSCs with a basal cell carcinoma-to-squamous cell carcinoma ratio of 1.8:1. The actuarial risk for development of a second NMSC was 13.7% at 1 year, 28.4% at 2 years, 49.4% at 5 years, 65.7% at 10 years, and 88.4% at 15 years. Multivariate analysis found that skin phototype I or II (vs III or IV) was a significant risk factor for development of a second NMSC (hazard ratio, 2.556; 95% confidence interval, 1.45-4.48; P = .001), whereas withdrawal of calcineurin inhibitors was significantly protective (hazard ratio, 0.358; 95% confidence interval, 0.142-0.902; P = .029). LIMITATIONS: Retrospective analysis. CONCLUSIONS: Subsequent NMSCs are very frequent in LTRs, and conversion from a calcineurin inhibitor-based immunosuppressive regimen to a mammalian target of rapamycin inhibitor/antimetabolite-based immunosuppressive regimen can reduce subsequent NMSCs.

BACKGROUND: Chronic hepatitis C virus (HCV) infection is the most common chronic liver disease in patients with end-stage renal disease (ESRD). Over the last few years, second-generation direct-acting antivirals have been revolutionary in the treatment of hepatitis C, and sofosbuvir (SOF) is the backbone of most modern treatment strategies. Since SOF is eliminated through the kidney, the aim of this multicentre retrospective study was to assess its antiviral efficacy and safety in HCV-infected patients with severe renal failure [including haemodialysis (HD) patients]. METHODS: Fifty patients (36 males, mean age ± standard deviation 60.5 ± 7.5 years) with chronic HCV infection (G1: 28/56%, cirrhosis: 27/54%) and severe renal failure [i.e. MDRD estimated glomerular filtration rate (eGFR) <35 mL/min], including 35 on HD, were enrolled. Antiviral treatment consisted of SOF/ribavirin (RBV) (n = 7), SOF/RBV/pegylated interferon (n = 2), SOF/daclatasvir ± RBV (n = 30) or SOF/simeprevir ± RBV (n = 11) for 12 or 24 weeks. A reduced dose of SOF (400 mg three times a week or 400 mg every other day) was given to all HD patients. Initial dose of RBV (n = 12) ranged from 400 to 4200 mg/week. RESULTS: On an intent-to-treat-based analysis, sustained virological response rate was 86% at 12 weeks. During therapy, haemoglobin levels were not significantly modified, but recombinant erythropoietin (rEPO) dose significantly increased in patients treated with RBV. Two patients (4%) required blood transfusion. No patient had treatment discontinuation due to side effects. Dose of RBV was reduced in two patients (16.7%) during antiviral therapy. Dose of SOF was reduced in two non-HD patients because of side effects. In non-HD patients, median eGFR was not significantly modified during treatment. CONCLUSIONS: Our results strongly suggest that SOF-based antiviral therapy, with a reduced dose of SOF, is safe and effective for the treatment of HCV patients with ESRD, including HD patients.

BACKGROUND: The aim of this work is to report our early experiences about the benefits of liver transplantation (LT) in the treatment of persistent neurological symptoms in Wilson's disease (WD) patients. METHODS: We describe our findings in 4 WD patients with neurological impairment or symptoms treated by LT: 2 patients had transplants due to worsening of neurological symptoms despite long-term appropriate medical treatment. The other 2 required LT because of symptoms associated with liver failure. Patients were evaluated using the modified Rankin scale and the Unified Wilson's Disease Rating Scale (UWDRS). RESULTS: The 4 patients experienced neurological improvement after LT. The pre-LT Rankin score of the 2 patients transplanted due to neurological impairment was 4 compared to 3 and 2, respectively, post LT. The pre-LT Rankin scores of the 2 WD cases transplanted because of hepatic failure were 1 and 2, respectively, compared to 0 in both cases post LT. UWDRS score improved in 2 cases and remained stable in 1 less severely impaired case. Brain MRI abnormalities proved partially reversible in 3 patients and remained stable for 1 patient. CONCLUSIONS: These results suggest that LT could be envisaged for neurologically impaired WD patients.
