Abstract
BACKGROUND & AIMS We performed a prospective study to investigate the effects of a sustained viral response (SVR) on outcomes of patients with hepatitis C virus (HCV) infection and compensated cirrhosis. METHODS We collected data from 1323 patients included in the prospective Agence Nationale pour la Recherche sur le SIDA et les hépatites virales (ANRS) viral cirrhosis (CirVir) cohort, recruited from 35 clinical centers in France from 2006 through 2012. All patients had HCV infection and biopsy-proven cirrhosis, were Child-Pugh class A, and had no prior liver complications. All patients received anti-HCV treatment before or after inclusion (with interferon then with direct antiviral agents) and underwent an ultrasound examination every 6 months, as well as endoscopic evaluations. SVR was considered as a time-dependent covariate; its effect on outcome was assessed by the Cox proportional hazard regression method. We used a propensity score to minimize confounding by indication of treatment and capacity to achieve SVR. RESULTS After a median follow-up period of 58.2 months, 668 patients (50.5%) achieved SVR. SVR was associated with a decreased incidence of hepatocellular carcinoma (hazard ratio [HR] compared with patients without an SVR, 0.29; 95% confidence interval [CI], 0.19-0.43; P < .001) and hepatic decompensation (HR, 0.26; 95% CI, 0.17-0.39; P < .001). Patients with SVRs also had a lower risk of cardiovascular events (HR, 0.42; 95% CI, 0.25-0.69; P = .001) and bacterial infections (HR, 0.44; 95% CI, 0.29-0.68; P < .001). Metabolic features were associated with a higher risk of hepatocellular carcinoma in patients with SVRs, but not in patients with viremia. SVR affected overall mortality (HR, 0.27 compared with patients without SVR; 95% CI, 0.18-0.42; P < .001) and death from liver-related and non-liver-related causes. Similar results were obtained in a propensity score-matched population. CONCLUSIONS We confirmed a reduction in critical events, liver-related or not, in a prospective study of patients with HCV infection and compensated cirrhosis included in the CirVir cohort who achieved an SVR. We found an SVR to reduce overall mortality and risk of death from liver-related and non-liver-related causes. A longer follow-up evaluation is required to accurately describe and assess specific risk factors for complications in this population.

Abstract
Essentials Endothelial injury is thought to be a key event in thrombotic thrombocytopenic purpura (TTP). Endothelial and cardiac damages were assessed in a model of TTP using ADAMTS-13 knockout mice. Damages of cardiac perfusion and function were associated with nitric oxide pathway alteration. Endothelial dysfunction constitutes a critical event in TTP development and cardiac injury. SUMMARY Background Cardiac alterations represent a major cause of mortality in patients with thrombotic thrombocytopenic purpura (TTP). Endothelial injury remains poorly defined, but seems to be a key initiating event leading to the formation of platelet-rich thrombi in TTP patients. Objectives To assess the changes in endothelial function and the induced cardiac damage in a mouse model of TTP. Patients/methods We used an animal model in which TTP-like symptoms are triggered by injection of 2000 units kg-1 of recombinant von Willebrand factor in ADAMTS-13 knockout mice. Results These mice developed TTP-like symptoms, i.e. severe thrombocytopenia, schistocytosis, and anemia. On day 2, magnetic resonance imaging demonstrated a decrease in left ventricular perfusion associated with alteration of left ventricular ejection fraction, fractional shortening, and cardiac output, suggesting early systolic dysfunction. This was associated with decrease in endothelium-mediated relaxation responses to acetylcholine in mesenteric and coronary arteries, demonstrating severe early endothelial dysfunction. In parallel, we showed decreased cardiac expression of endothelial nitric oxide (NO) synthase and increased expression of antioxidant enzymes, suggesting alteration of the NO pathway. At this time, cardiac immunohistochemistry revealed an increase in the expression of VCAM-1 and E-selectin. Conclusion This study provides evidence that the heart is a sensitive target organ in TTP, and shows, for the first time, strong mesenteric and coronary endothelial dysfunction in an induced-TTP model. The mechanisms incriminated are the occurrence of a pro-oxidant state, and proadhesive and proinflammatory phenotypes. This previously largely unrecognized vascular dysfunction may represent an important contributor to the systemic organ failure occurring in TTP.

Abstract
UNLABELLED The aim of this work was to develop an individualized score for predicting hepatocellular carcinoma (HCC) in patients with hepatitis C (HCV)-compensated cirrhosis. Among 1,323 patients with HCV cirrhosis enrolled in the French prospective ANRS CO12 CirVir cohort, 720 and 360 were randomly assigned to training and validation sets, respectively. Cox's multivariate model was used to predict HCC, after which a nomogram was computed to assess individualized risk. During follow-up (median, 51.0 months), 103 and 39 patients developed HCC in the training and validation sets, respectively. Five variables were independently associated with occurrence of HCC: age > 50 years (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.16; 3.25; P = 0.012); past excessive alcohol intake (HR, 1.55; 95% CI, 1.02; 2.36; P = 0.041); low platelet count (<100 Giga/mm(3) : HR, 2.70; 95% CI, 1.62; 4.51; P < 0.001; [100; 150] Giga/mm(3) : HR, 1.87; 95% CI, 1.10; 3.18; P = 0.021); gamma-glutamyl transpeptidase above the upper limit of normal (HR, 1.96; 95% CI, 1.11; 3.47; P = 0.021); and absence of a sustained virological response during follow-up (HR, 3.02; 95% CI, 1.67; 5.48; P < 0.001). An 11-point risk score was derived from the training cohort and validated in the validation set. Based on this score, the population was stratified into three groups, in which HCC development gradually increased, from 0% to 30.1% at 5 years for patients with the lowest (≤3) and highest (≥8) scores (P < 0.001). Using this score, a nomogram was built enabling individualized prediction of HCC occurrence at 1, 3, and 5 years. CONCLUSION This HCC score can accurately predict HCC at an individual level in French patients with HCV cirrhosis. (Hepatology 2016;64:1136-1147).

Abstract
BACKGROUND To shorten the course of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, we examined the antiviral efficacy and safety of 3 weeks of response-guided therapy with an NS3 protease inhibitor and dual NS5A inhibitor-NS5B nucleotide analogue. METHODS In this open-label, phase 2a, single centre study, Chinese patients with chronic HCV genotype 1b infection without cirrhosis were randomly allocated by a computer program to one of three treatment groups (sofosbuvir, ledipasvir, and asunaprevir; sofosbuvir, daclatasvir, and simeprevir; or sofosbuvir, daclatasvir, and asunaprevir) until six patients in each group (1:1:1) achieved an ultrarapid virological response (plasma HCV RNA <500 IU/mL by day 2, measured by COBAS TaqMan HCV test, version 2.0). Patients with an ultrarapid virological response received 3 weeks of therapy. Patients who did not achieve an ultrarapid response were switched to sofosbuvir and ledipasvir for either 8 weeks or 12 weeks. The primary endpoint was the proportion of patients with a sustained virological response at 12 weeks (SVR12) after treatment completion, analysed in the intention-to-treat population. All patients who achieved an ultrarapid virological response were included in the safety analysis. This trial is registered with ClinicalTrials.gov, number NCT02470858. FINDINGS Between April 5, 2015, and April 15, 2015, 26 eligible patients were recruited. 12 patients were assigned to sofosbuvir, ledipasvir, and asunaprevir; six to sofosbuvir, daclatasvir, and simeprevir; and eight to sofosbuvir, daclatasvir, and asunaprevir. Six patients in each group achieved an ultrarapid virological response (18 [69%]). All patients with an ultrarapid virological response who were given 3 weeks of triple therapy achieved SVR12. The most common adverse events were fatigue (one [17%] of six patients receiving sofosbuvir, ledipasvir, and asunaprevir; one [17%] of six patients receiving sofosbuvir, daclatasvir, and simeprevir; and two [33%] of six patients receiving sofosbuvir, daclatasvir, and asunaprevir) and headache (one [17%] patient in each group). No patients experienced any serious adverse events. INTERPRETATION In this proof-of-concept study, all patients with chronic HCV without cirrhosis who achieved an ultrarapid virological response on triple direct-acting antiviral regimens by day 2 and received 3 weeks of treatment were cured, with excellent tolerability. By shortening the duration of therapy from the currently recommended 12 weeks to 3 weeks, we could drastically reduce the cost of therapy and the rate of adverse events. Further large-scale studies should be done to confirm our findings.

Abstract
PURPOSE Data on long-term treatment with low-molecular-weight heparins (LMWH) in cancer patients treated for venous thromboembolism are scarce. Study objectives were to document the long-term clinical use of LMWH and patient perception in this setting. METHODS Adult cancer patients receiving antineoplastic treatment or palliative care and LMWH for cancer associated venous thromboembolism (CAT) were eligible to participate in this prospective observational study. Main outcome was adherence to clinical practice guidelines based on recommended LMWH treatment doses for at least 3months in the absence of severe renal insufficiency. Patients' perception of the treatment was assessed in an ancillary study using the Perception Anticoagulant Treatment Questionnaire (PACT-Q). RESULTS Among 409 included cancer patients aged 65±12.1years, overall adherence to practice guidelines as defined in the protocol was 55.3% (226 patients). However, 98.0% of patients received a prescription for 3months or more and mean LMWH treatment duration for VTE was 6.27±0.15months which meets guidelines recommendations. Main patients' expectations scored on a 1-5 scale were blood clots prevention (mean 3.94±0.75), symptom relief (mean 3.98±1.04) and ease of use (mean 4.22±0.9). LMWH treatment appeared convenient (global score 79.7±17.1 on a 0 to 100 scale) and 69.1% of patients were satisfied or very satisfied. CONCLUSION Despite incomplete strict adherence to guidelines, treatment duration with LMWH was adequate showing substantial progress in the management of CAT patients. Patients expectations were high while treatment was perceived convenient with a high degree of satisfaction.

Abstract
The "Hallmarks of Cancer" describe the ways by which cancer cells bypass homeostasis. Escape from replicative senescence is one of the earliest features of cancer cells. Maintenance of the telomeres through reactivation of telomerase was initially associated with replicative immortality in various cancers. The shelterin complex, a telomeric hexaprotein association, plays a key role in telomere maintenance and in the hallmarks of cancer. Some shelterin proteins are overexpressed in diverse cancers and can promote tumorigenesis in animal models. Shelterin can also have an impact on tumor size, tumor growth and resistance to treatment. Studies into the expression level of shelterin in oral squamous cell carcinoma (OSCC) report contradictory results. Moreover, the exact role of these proteins in OSCC tumorigenesis remains uncertain. In this review, we examined the data linking telomeres and hallmarks of OSCC. Furthermore, we examined the literature concerning telomeres and the clinical outcome of OSCC. Finally, we propose a model encompassing the role of shelterin proteins in oral tumorigenesis and treatment outcome.

Abstract
UNLABELLED Various critical events, liver related or not, occur in patients with compensated cirrhosis, but their respective burden remains to be prospectively assessed. The aim of this prospective cohort study involving 35 French centers was to capture the whole spectrum of complications occurring in compensated viral cirrhosis (VC) using competing risks analyses. Inclusion criteria were: histologically proven cirrhosis resulting from hepatitis C virus (HCV) or hepatitis B virus (HBV); Child-Pugh A; and no previous hepatic complications. The cohort was considered as a multistate disease model, cumulative incidences (CumIs) of events were estimated in a competing risks framework. A total of 1,654 patients were enrolled from 2006 to 2012 (HCV, 1,308; HBV, 315; HCV-HBV, 31). During a median follow-up of 34 months, at least one liver nodule was detected in 271 patients, confirmed as hepatocellular carcinoma (HCC) in 128 (4-year cumI: 10.5%) and cholangiocarcinoma in 3. HCC incidence was higher in HCV (4-year cumI: 11.4% vs. 7.4%; P = 0.05). HCC fulfilled Milan criteria in 79.3%, leading to curative treatment in 70.4%. Liver decompensation occurred more frequently in HCV patients (4-year cumI: 10.8% vs. 3.6%; P = 0.0004). Virological eradication/control was achieved in 34.1% of HCV and 88.6% of HBV patients and was associated with a marked decrease in HCC, decompensation, and bacterial infection incidences. Survival was shorter in HCV patients (4-year cumI: 91.6% vs. 97.2%; P = 0.0002). Death (n = 102; missing data: 6) was attributed to liver disease in 48 (47%; liver cancer: n = 18; miscellaneous, n = 30) and extrahepatic causes in 48 (47%; bacterial infection: n = 13; extrahepatic cancers: n = 10; cardiovascular events: n = 5; miscellaneous, n = 20). CONCLUSION After 3 years of follow-up, extrahepatic events still explained half of deaths in patients with compensated VC. A strong decrease in complications was linked to virological eradication/control.

Abstract
INTRODUCTION While in most countries warfarin is the preferred anti-vitamin K, fluindione, a molecule with a prolonged half-life remains largely prescribed in France. Some of its side effects, including immuno-allergic complications, remain poorly understood. CASE REPORT A 77-year-old woman presented with a febrile severe neutropenia of immunoallergic mechanism with a favourable outcome associated with fluindione, introduced 25 days earlier for the treatment of atrial fibrillation. CONCLUSION This rare side effect is a reminder of the importance of biological monitoring in the first weeks following the introduction of fluindione and key diagnostic elements and therapeutic aspects of iatrogenic agranulocytosis.

Abstract
BACKGROUND Cardiac involvement is a major cause of mortality in patients with thrombotic thrombocytopenic purpura (TTP). However, diagnosis remains underestimated and delayed, owing to subclinical injuries. Cardiac troponin-I measurement (cTnI) on admission could improve the early diagnosis of cardiac involvement and have prognostic value. OBJECTIVES To assess the predictive value of cTnI in patients with TTP for death or refractoriness. PATIENTS/METHODS The study involved a prospective cohort of adult TTP patients with acquired severe ADAMTS-13 deficiency (< 10%) and included in the registry of the French Reference Center for Thrombotic Microangiopathies. Centralized cTnI measurements were performed on frozen serum on admission. RESULTS Between January 2003 and December 2011, 133 patients with TTP (mean age, 48 ± 17 years) had available cTnI measurements on admission. Thirty-two patients (24%) had clinical and/or electrocardiogram features. Nineteen (14.3%) had cardiac symptoms, mainly congestive heart failure and myocardial infarction. Electrocardiogram changes, mainly repolarization disorders, were present in 13 cases. An increased cTnI level (> 0.1 μg L(-1) ) was present in 78 patients (59%), of whom 46 (59%) had no clinical cardiac involvement. The main outcomes were death (25%) and refractoriness (17%). Age (P = 0.02) and cTnI level (P = 0.002) showed the greatest impact on survival. A cTnI level of > 0.25 μg L(-1) was the only independent factor in predicting death (odds ratio [OR] 2.87; 95% confidence interval [CI] 1.13-7.22; P = 0.024) and/or refractoriness (OR 3.03; 95% CI 1.27-7.3; P = 0.01). CONCLUSIONS A CTnI level of > 0.25 μg L(-1) at presentation in patients with TTP appears to be an independent factor associated with a three-fold increase in the risk of death or refractoriness. Therefore, cTnI level should be considered as a prognostic indicator in patients diagnosed with TTP.

Abstract
INTRODUCTION Rituximab is a monoclonal antibody targeting the CD20 molecule of the B lymphocyte. Its efficacy has been recently reported in ANCA-associated vasculitis. We report a case of psoriatic arthritis that occurs during a treatment with rituximab in granulomatosis with polyangiitis. CASE REPORT A 66-year-old woman, without past history of psoriasis, presented with a relapsing granulomatosis with polyangiitis in July 2010 with sinus and lung involvement. Treatment with rituximab was started, allowing a complete remission in 6 months. Two months after the first two infusions of rituximab she developed asymmetric arthritis of 3 distal interphalangeal joints. A few months later, the clinical presentation showed asymmetrical arthritis of the hands and wrists and dactylitis. Standard radiographs and MRI showed an inflammatory impairment according with psoriatic arthritis. CONCLUSION Accountability of rituximab was retained in the development of the disease given the chronology of psoriatic arthritis development. It may be a paradoxical reaction, by analogy to those observed in anti-TNFα.

Abstract
INTRODUCTION Venous thromboembolism and dehydration are frequent conditions in elderly. The objective of this study was to assess the prevalence of dehydration in patients aged over 70 years suspected of deep vein thrombosis (DVT). METHODS This is a prospective observational study that included patients aged over 70 years and suspected of deep vein thrombosis. Clinical and biological dehydration was diagnosed on the presence of a skin fold, a weight loss≥5%, a thirst, a plasmatic osmolality>295 mOsm/L or blood urea nitrogen/creatinine ratio>20. RESULTS One hundred and forty-four patients (mean age 81.8±5.8 years) were included. A diagnosis of DVT was retained in 97 patients. Clinical dehydration was not more frequent in the DVT+ group (37.2% vs 35.1%). At baseline, 69.1% of DVT+ patients and 53.2% of DVT- patients had a plasma osmolality greater than 295 mosm/L (NS). BUN/creatinine ratio greater than 20 was found in 58.8% of DVT+ patients and 72.3% of DVT- patients (NS). Clinical and biological dehydration was present in 28.6% of DVT+ patients and in 33.3% of DVT- patients (NS). The positive predictive value of the Wells score≥3 was 86.5%, and negative predictive value of a Wells score≤0 was 85%. CONCLUSION The presence of dehydration does not appear predictive of the occurrence of DVT and does not influence the statistical performance of the Wells score in elderly patients.

Abstract
BACKGROUND & AIMS Few data are available on the prevalence of renal abnormalities in chronic hepatitis B virus (HBV)-infected patients. The multicentric cross-sectional HARPE study evaluated the prevalence of kidney disease indicators, in chronic HBV surface antigen carriers patients (HBsAg+) with active or inactive infection. PATIENTS AND METHODS Two hundred and sixty-eight HBsAg+ adult patients, naïve of any oral antihepatitis B virus treatment were prospectively included over 2 years. Data for renal assessment were collected once from patient files. Univariate tests and multiple linear regressions were performed with the SAS software, version 8.02 (SAS, Inc., Cary, NC, USA). RESULTS Among the 260 patients analysed, 58% were men, the mean age was 42 ± 14 years, 59.6% were inactive carriers whereas 47 patients, mostly active, were about to start an antiviral therapy. Prevalence of proteinuria, haematuria, glycosuria, uninfectious leukocyturia was 38.1%, 20.6%, 3.9% and 9% respectively. According to the international definition, a total of 64.6% of patients were found to have kidney disease. Diabetes, hypertension and dyslipidaemia were observed, respectively, in 4.6%, 9.2% and 38.8% patients. There were no significant differences in these results within the three subgroups. CONCLUSION Renal abnormalities are highly prevalent in our population and pre-exist before the initiation of any antihepatitis B virus treatment. This emphasizes the need for: (i) a baseline renal evaluation in all HBs antigen-positive patients; (ii) a regular renal monitoring before and during antihepatitis B virus treatment to diagnose and manage renal impairment and adjust antihepatitis B virus treatment doses to renal function when necessary.

Abstract
Chronic hepatitis C virus (HCV) causes chronic liver injury and can lead to cirrhosis and hepatocellular carcinoma (HCC). HCV can also interact with the immune system to cause several HCV related disorders including essential mixed cryoglobulinemia, vasculitis, dermatitis, glomerulonephritis and lymphoma. A strong association between HCV and diabetes mellitus also exists. These extrahepatic features may lead to increased fatigue and a reduced quality of life. It is now possible to cure most patients with chronic HCV using oral antiviral therapy. Many of these HCV-related disorders and symptoms can be cured when HCV is eradicated. However, some patients may have irreversible injury to extrahepatic sites, cirrhosis that cannot resolve, an increased risk for HCC, persistent fatigue and a reduced quality of life, despite achieving sustained virological response.
