RESUMO

BACKGROUND AND AIM: Germline mutations of telomere-related genes (TRG) induce multiorgan dysfunction, and liver-specific manifestations have not been clearly outlined. We aimed to describe TRG mutations-associated liver diseases. APPROACH AND RESULTS: Retrospective multicenter analysis of liver disease (transaminases > 30 IU/L and/or abnormal liver imaging) in patients with TRG mutations. Main measurements were characteristics, outcomes, and risk factors of liver disease in a TRG mutations cohort. The prevalence of liver disease was compared to a community-based control group (n = 1190) stratified for age and matched 1:3 for known risk factors of liver disease. Among 132 patients with TRG mutations, 95 (72%) had liver disease, with associated lung, blood, skin, rheumatological, and ophthalmological TRG diseases in 82%, 77%, 55%, 39%, and 30% of cases, respectively. Liver biopsy was performed in 52/95 patients, identifying porto-sinusoidal vascular disease in 48% and advanced fibrosis/cirrhosis in 15%. After a follow-up of 21 months (12-54), ascites, hepato-pulmonary syndrome, variceal bleeding, and HCC occurred in 14%, 13%, 13%, and 2% of cases, respectively. Five-year liver transplantation-free survival was 69%. A FIB-4 score ≥ 3·25 and ≥1 risk factor for cirrhosis were associated with poor liver transplantation-free survival. Liver disease was more frequent in patients with TRG mutations than in the paired control group [80/396, (20%)], OR 12.9 (CI 95%: 7.8-21.3, p < 0.001). CONCLUSIONS: TRG mutations significantly increase the risk of developing liver disease. Although symptoms may be mild, they may be associated with severe disease. Porto-sinusoidal vascular disease and cirrhosis were the most frequent lesions, suggesting that the mechanism of action is multifactorial.

RESUMO

BACKGROUND & AIMS: The harmful impact of heavy alcohol consumption and recurrence in patients with alcohol-related cirrhosis is long-established, although this is based on old studies. However, the drivers of long-term outcome still need to be clearly investigated. METHOD: All patients with biopsy-proven compensated alcohol-related cirrhosis included in the CIRRAL cohort (22 centers) were prospectively studied. Prognostic variables of survival and liver event-free survival were assessed using multivariable Cox models with stepwise selection. The prognostic impact of alcohol recurrence during follow-up (computed in glass-years in the same way as pack-years for tobacco) was assessed using a time-dependent covariable. RESULTS: From 2010 to 2016, 650 patients were included. The median age at baseline was 58.4 years, 67.4% were men and the median BMI was 27.8 kg/m2, 63.8% had a history of liver decompensation, and 70.2% had discontinued alcohol. At 5 years, recurrence occurred in 30.9% of abstinent patients and this risk was higher in patients with a history of drug abuse and in those with shorter alcohol discontinuation times. Median survival was 97 months. Age, alcohol consumption at baseline, platelet count and Child-Pugh score >5 were associated with overall and liver event-free survival on multivariate analysis. Alcohol consumption of more than 25 glass-years during follow-up was independently associated with lower survival and with a trend toward lower liver event-free survival, with the risk increasing from 1 glass-year, though not significantly. Simon & Makuch plots confirm the benefit of no alcohol consumption (<1 glass/week) on both outcomes and the dose-dependent impact of alcohol over time. CONCLUSION: This prospective study in patients with compensated alcohol-related cirrhosis identifies factors predictive of alcohol recurrence during follow-up and shows that moderate alcohol consumption during follow-up negatively impacts outcomes. Patients with alcohol-related cirrhosis should be advised to completely stop drinking alcohol. REGISTRATION: CIRRAL (NCT01213927) cohort was registered at ClinicalTrials.gov and the full protocol is available at the following link: https://clinicaltrials.gov/ct2/show/NCT01213927. IMPACT AND IMPLICATIONS: In patients with alcohol-related cirrhosis, data are lacking about the impact of the amount of alcohol consumed on both survival and liver-related events. The present study based on the CIRRAL cohort demonstrates that alcohol recurrence occurs in more than 30% of patients with compensated cirrhosis and that even a moderate recurrence strongly influences outcomes. Patients with compensated alcohol-related cirrhosis should be advised to completely discontinue alcohol consumption, even in small amounts, as the present study shows that no alcohol consumption can be regarded as safe when cirrhosis has developed.

RESUMO

Data on efficacy and safety of sorafenib in a neoadjuvant setting for HCC awaiting liver transplantation (LT) are heterogeneous and scarce. We aimed to investigate the trajectory of patients treated with sorafenib while awaiting LT. All patients listed for HCC and treated with sorafenib were included in a monocentric observational study. A clinical and biological evaluation was performed every month. Radiological tumor response evaluation was realized every 3 months on the waiting list and every 6 months after LT. Among 327 patients listed for HCC, 62 (19%) were treated with Sorafenib. Sorafenib was initiated for HCC progression after loco-regional therapy (LRT) in 50% of cases and for impossibility of LRT in 50% of cases. The mean duration of treatment was 6 months. Thirty six patients (58%) dropped-out for tumor progression and 26 (42%) patients were transplanted. The 5-year overall and recurrent-free survival after LT was 77% and 48% respectively. Patients treated for impossibility of LRT had acceptable 5-year intention-to-treat overall and post-LT survivals. Conversely, patients treated for HCC progression presented high dropout rate and low intention-to-treat survival. Our results suggest that it is very questionable in terms of utility that patients treated for HCC progression should even be kept listed once the tumor progression has been observed.

RESUMO

BACKGROUND AND AIMS: Non-O blood group promotes deep vein thrombosis and liver fibrosis in both general population and hepatitis C. We aimed to evaluate the influence of Non-O group on the outcome of Child-Pugh A cirrhotic patients. METHODS: We used two prospective cohorts of Child-Pugh A cirrhosis due to either alcohol or viral hepatitis. Primary end point was the cumulated incidence of 'Decompensation' at 3 years, defined as the occurrence of ascites , hydrothorax, encephalopathy, gastrointestinal bleeding related to portal hypertension, or bilirubin >45 µmol/L. Secondary end points were the cumulated incidences of (1) 'Disease Progression' including a « decompensation¼ or « the occurrence of one or more parameters ¼ among: prothrombin time (PT) <45%, albumin <28 g/L, Child-Pugh worsening (B or C vs A or B, C vs B), hepatorenal syndrome, and hepato-pulmonary syndrome, (2) other events such as non-malignant portal vein thrombosis (nmPVT), and (3) overall survival. RESULTS: Patients (n = 1789; 59.9% Non-O group; 40.1% group O) were followed during a median of 65.4 months. At 3 years cumulated incidence of Decompensation was 8.3% in Non-O group and 7.2% in group O (P = .27). Cumulated incidence of Disease Progression was 20.7% in Non-O group and 18.9% in group O (P = .26). Cumulated incidence of nmPVT was 2.7% in Non-O group and 2.8% in group O (P = .05). At 3 years overall survival was 92.4% in Non-O group and 93.4% in group O (P = 1). CONCLUSION: Non-O group does not influence disease outcome in Child-Pugh A cirrhotic patients. Clinicals trial number NCT03342170.

RESUMO

BACKGROUND & AIMS: Recent non-malignant non-cirrhotic portal venous system thrombosis (PVT) is a rare condition. Among risk factors for PVT, cytomegalovirus (CMV) disease is usually listed based on a small number of reported cases. The aim of this study was to determine the characteristics and outcomes of PVT associated with CMV disease. METHODS: We conducted a French multicenter retrospective study comparing patients with recent PVT and CMV disease ("CMV positive"; n = 23) to patients with recent PVT for whom CMV testing was negative ("CMV negative"; n = 53) or unavailable ("CMV unknown"; n = 297). RESULTS: Compared to patients from the "CMV negative" and "CMV unknown" groups, patients from the "CMV positive" group were younger, more frequently had fever, and had higher heart rate, lymphocyte count and serum ALT levels (p ≤0.01 for all). The prevalence of immunosuppression did not differ between the 3 groups (4%, 4% and 6%, respectively). Extension of PVT was similar between the 3 groups. Thirteen out of 23 "CMV positive" patients had another risk factor for thrombosis. Besides CMV disease, the number of risk factors for thrombosis was similar between the 3 groups. Heterozygosity for the prothrombin G20210A gene variant was more frequent in "CMV positive" patients (22%) than in the "CMV negative" (4%, p = 0.01) and "CMV unknown" (8%, p = 0.03) groups. Recanalization rate was not influenced by CMV status. CONCLUSIONS: In patients with recent PVT, features of mononucleosis syndrome should raise suspicion of CMV disease. CMV disease does not influence thrombosis extension nor recanalization. More than half of "CMV positive" patients have another risk factor for thrombosis, with a particular link to the prothrombin G20210A gene variant. LAY SUMMARY: Patients with cytomegalovirus (CMV)-associated portal venous system thrombosis have similar thrombosis extension and evolution as patients without CMV disease. However, patients with CMV-associated portal venous system thrombosis more frequently have the prothrombin G20210A gene variant, suggesting that these entities act synergistically to promote thrombosis.

RESUMO

Transarterial chemoembolization (TACE) is used to treat patients with unresectable hepatocellular carcinoma (HCC). We evaluated the clinical impact of a-fetoprotein (AFP) and circulating cell-free and tumor DNA (cfDNA and ctDNA) changes around the TACE procedure. Our prospective monocentric study enrolled consecutive patients treated with TACE, with samples collected at baseline (D - 1), Day 2 (D + 2) and 1 month (M + 1) after TACE. cfDNA was quantified by the fluorometric method, and ctDNA was quantified by digital polymerase chain reaction designed for two hotspot TERT mutations. Computerized tomography scans or magnetic resonance imaging were performed at M + 1 every 3 months following TACE and independently reviewed. The objective was to identify thresholds of cfDNA, ctDNA and AFP changes associated with progressive disease (PD) using receiver operating characteristic curves. Thirty-eight patients were included from March 2018 to March 2019. All markers significantly increased from D - 1 to D + 2 (P < .005), and cfDNA and ctDNA significantly decreased from D + 2 to M + 1 (P < .0001). The analysis of changes from D - 1 to M + 1 identified thresholds at +31.4% for cfDNA and 0% for ctDNA that were significantly associated with PD at M + 1 (44.4% [>+31.4%] vs 3.8% [≤+31.4%] and 50.0% [>0%] vs 5.0% [≤0%], respectively). No significant threshold was identified for AFP. Using a score combining cfDNA and ctDNA, the patients were classified into high- or low-risk PD groups at M + 1, with PD rates of 80.0% vs 4.3% (P = .001) and median progression-free survival times of 1.3 vs 10.3 months (P = .002). Our study suggests that cfDNA and ctDNA increases around the TACE procedure and are associated with therapeutic failure.

RESUMO

Myeloproliferative neoplasms (MPNs) are the most frequent underlying causes of splanchnic vein thromboses (SVTs). MPN patients with SVTs (MPN-SVT) often have a unique presentation including younger age, female predominance, and low Janus kinase 2 (JAK2) mutation allele burden. This study aimed at identifying risk factors for adverse hematologic outcomes in MPN-SVT patients. We performed a retrospective study of a fully characterized cohort of MPN-SVT patients. The primary outcome was the incidence of evolution to myelofibrosis, acute leukemia, or death. Eighty patients were included in the testing cohort. Median follow-up was 11 years. Most of the patients were women with a mean age of 42 years and a diagnosis of polycythemia vera. The primary outcome was met in 13% of the patients and was associated with a JAK2V617F allele burden ≥50% (odds ratio [OR], 14.7) and presence of additional mutations in genes affecting chromatin/spliceosome (OR, 9). We identified high-risk patients (29% of the cohort) as those harboring at least 1 molecular risk factor: JAK2-mutant allele burden ≥50%, presence of chromatin/spliceosome/TP53 mutation. High-risk patients had worse event-free survival (81% vs 100%; P = .001) and overall survival at 10 years (89% vs 100%; P = .01) than low-risk patients. These results were confirmed in an independent validation cohort of 30 MPN-SVT patients. In conclusion, molecular profiling identified MPN-SVT patients with dismal outcome. In this high-risk population, a disease-modifying therapy should be taken into consideration to minimize the probability of transformation.

RESUMO

BACKGROUND & AIMS: Management of patients with cirrhosis includes endoscopic screening and surveillance to detect esophageal varices (EV) and prevent bleeding. However, the Baveno VI guidelines recommend avoiding endoscopies for patients with liver stiffness measurements below 20 kPa and platelet counts above 150,000 (favorable Baveno VI status) and endoscopic assessment of patients with higher levels of liver stiffness and platelet counts (unfavorable Baveno VI status). We aimed to validate the Baveno VI guidelines, evaluating outcomes of patients in the ANRS-CO12 CirVir cohort with compensated cirrhosis associated with hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, with or without a sustained response to antiviral therapy. METHODS: We performed an ancillary study using data from 891 patients in the ANRS CO12 CirVir cohort, treated at 35 centers in France, with HCV or HBV infection and biopsy-proven cirrhosis, Child-Pugh A scores, no previous complications, and no hepatocellular carcinoma who underwent an endoscopic procedure and had interpretable liver stiffness measurements and platelet counts. Progression of portal hypertension (PHT) was defined as the onset of varices needing treatment (VNT) or PHT-related bleeding. An sustained response to antiviral therapy was defined as undetectable level of HCV RNA by polymerase chain reaction assay (<50 IU/mL) 12 weeks after the end of treatment (SVR) or an undetectable level of HBV DNA. The primary aims were to validate the Baveno VI guidelines for screening and surveillance of EV in patients with compensated cirrhosis and to study the effects of an SVR on the progression of PHT. RESULTS: A total of 200 patients achieved an SVR (22.4%) (94 patients with HCV infection, 98 patients with HBV infection, and 8 patients with both); 80 of these patients had favorable Baveno VI status and none had VNT. Progression of PHT was studied in 548 patients; during a follow-up period of 61.2 months (interquartile range, 39.5-80.6 months), 105 of these patients (19.1%) had progression of PHT. Lack of an SVR and grade 1 EV were independently associated with progression of PHT. At the time of PHT progression, all patients had unfavorable Baveno VI status. Achieving favorable Baveno VI status after an SVR was associated with the absence of PHT progression. Favorable Baveno VI status and SVR were independently associated with survival. CONCLUSIONS: In an analysis of data from a large cohort of patients with HBV- or HCV-associated cirrhosis in France, we validated the Baveno VI guidelines on screening and surveillance of PHT, even for patients who achieved a sustained response to antiviral therapy.

RESUMO

BACKGROUND & AIMS: More than 90% of cases of hepatocellular carcinoma (HCC) occur in patients with cirrhosis, of which alcohol is a major cause. The CIRRAL cohort aimed to assess the burden of complications in patients with alcoholic cirrhosis, particularly the occurrence of HCC. METHODS: Patients with biopsy-proven compensated alcoholic cirrhosis were included then prospectively followed. The main endpoint was the incidence of HCC. Secondary outcomes were incidence of hepatic focal lesions, overall survival (OS), liver-related mortality and event-free survival (EFS). RESULTS: From October 2010 to April 2016, 652 patients were included in 22 French and Belgian centers. During follow-up (median 29 months), HCC was diagnosed in 43 patients. With the limitation derived from the uncertainty of consecutive patients' inclusion and from a sizable proportion of dropouts (153/652), the incidence of HCC was 2.9 per 100 patient-years, and one- and two-year cumulative incidences of 1.8% and 5.2%, respectively. Although HCC fulfilled the Milan criteria in 33 cases (77%), only 24 patients (56%) underwent curative treatment. An explorative prognostic analysis showed that age, male gender, baseline alpha-fetoprotein, bilirubin and prothrombin were significantly associated with the risk of HCC occurrence. Among 73 deaths, 61 had a recorded cause and 27 were directly attributable to liver disease. At two years, OS, EFS and cumulative incidences of liver-related deaths were 93% (95% CI 90.5-95.4), 80.3% (95% CI 76.9-83.9), and 3.2% (95% CI 1.6-4.8) respectively. CONCLUSION: This large prospective cohort incompletely representative of the whole population with alcoholic cirrhosis showed: a) an annual incidence of HCC of up to 2.9 per 100 patient-years, suggesting that surveillance might be cost effective in these patients; b) a high proportion of HCC detected within the Milan criteria, but only one-half of detected HCC cases were referred for curative treatments; c) a two-year mortality rate of up to 7%. LAY SUMMARY: Cirrhosis is a risk factor for primary liver cancer, leading to recommendations for periodic screening. However, for alcohol-related liver disease the rational of periodic screening for hepatocellular carcinoma (HCC) is controversial, as registry and databased studies have suggested a low incidence of HCC in these patients and highly competitive mortality rates. In this study, a large cohort of patients with biopsy-proven alcoholic cirrhosis prospectively screened for HCC demonstrated a high annual incidence of HCC (2.9%) and a high percentage of small cancers theoretically eligible for curative treatment. This suggests that patients with liver disease related to alcohol should not be ruled out of screening.

RESUMO

INTRODUCTION: Epidemiological data is lacking on primary Budd-Chiari syndrome (BCS) in France. METHODS: Two approaches were used: (1) A nationwide survey in specialized liver units for French adults. (2) A query of the French database of discharge diagnoses screening to identify incident cases in adults. BCS associated with cancer, alcoholic/viral cirrhosis, or occurring after liver transplantation were classified as secondary. RESULTS: Approach (1) 178 primary BCS were identified (prevalence 4.04 per million inhabitants (pmi)), of which 30 were incident (incidence 0.68 pmi). Mean age was 40 ±â€¯14 yrs. Risk factors included myeloproliferative neoplasms (MPN) (48%), oral contraceptives (35%) and factor V Leiden (16%). None were identified in 21% of patients, ≥2 risk factors in 25%. BMI was higher in the group without any risk factor (25.7 kg/m2 vs 23.7 kg/m2, p < 0.001). Approach (2) 110 incident primary BCS were admitted to French hospitals (incidence 2.17 pmi). MPN was less common (30%) and inflammatory local factors predominated (39%). CONCLUSION: The entity of primary BCS as recorded in French liver units is 3 times less common than the entity recorded as nonmalignant hepatic vein obstruction in the hospital discharge database. The former entity is mostly related to MPN whereas the latter with abdominal inflammatory diseases.

RESUMO

BACKGROUND AND AIMS: Myeloproliferative neoplasms (MPN) are the leading cause of splanchnic vein thrombosis (SVT). Janus kinase 2 gene (JAK2)V617F mutations are found in 80 to 90% of patients with SVT and MPN. Mutations of the calreticulin (CALR) gene have also been reported. However, as their prevalence ranges from 0 to 2%, the utility of routine testing is questionable. This study aimed to identify a group of patients with SVT at high risk of harboring CALR mutations and thus requiring this genetic testing. METHODS: CALR, JAK2V617F and thrombopoietin receptor gene (MPL) mutations were analysed in a test cohort that included 312 patients with SVT. Criteria to identify patients at high risk of CALR mutations in this test cohort was used and evaluated in a validation cohort that included 209 patients with SVT. RESULTS: In the test cohort, 59 patients had JAK2V617F, five had CALR and none had MPL mutations. Patients with CALR mutations had higher spleen height and platelet count than patients without these mutations. All patients with CALR mutations had a spleen height ⩾16cm and platelet count >200×109/L. These criteria had a positive predictive value of 56% (5/9) and a negative predictive value of 100% (0/233) for the identification of CALR mutations. In the validation cohort, these criteria had a positive predictive value of 33% (2/6) and a negative predictive value of 99% (1/96). CONCLUSION: CALR mutations should be tested in patients with SVT, a spleen height ⩾16cm, platelet count >200×109/L, and no JAK2V617F. This strategy avoids 96% of unnecessary CALR mutations testing. Lay summary: Mutations of the CALR gene are detected in 0 to 2% of patients with SVT, thus the utility of systematic CALR mutation testing to diagnose MPN is questionable. This study demonstrates that CALR mutations testing can be restricted to patients with SVT, a spleen height ⩾16cm, a platelet count >200×109/L, and no JAK2V617F. This strategy avoids 96% of unnecessary CALR mutations testing.

RESUMO

OBJECTIVE: To assess incidence and prognostic significance of bacterial infections (BIs) occurring in compensated viral cirrhosis. DESIGN: This prospective study involved 35 French centres. Inclusion criteria were biopsy-proven HCV or HBV cirrhosis, Child-Pugh A and no previous hepatic complications. Cumulative incidence (CumI) of events was estimated in a competing risks framework. RESULTS: 1672 patients were enrolled (HCV 1323, HBV 318, HCV-HBV 31). During a median follow-up of 43 months, 234 BIs occurred in 171 patients (5 year CumI: 12.9%), among whom 14.6% had septic shock. Main localisations included the urinary tract (27.4%), lung (25.2%) and peritoneum (10.7%) (other, 86 (36.7%)). Most BIs occurred as a first event prior to liver decompensation (n=140, 81.8%) and were community-acquired (CA, 84.2%). The risk of BI was higher in patients with HCV than in patients with HBV (5 year CumI: 15.2% vs 5.5%, p=0.0008). Digestive localisation, concomitant interferon-based treatment, isolation of resistant bacteria and non-CA BIs were associated with lowest probability of resolution. The occurrence of a first BI impaired survival in patients infected with HCV (5 year survival: 60.2% vs 90.4%, p<0.001) and patients infected with HBV (5 year survival: 69.2% vs 97.6%, p<0.001). BIs represented the third cause of death (14.1%) after liver failure and liver cancer. BI risk factors comprised older age, lower albumin, proton pump inhibitor intake and absence of virological eradication/control. CONCLUSION: BI mostly occurs as a first complication and represents a turning point in the course of compensated viral cirrhosis. Its occurrence impacts long-term prognosis and may define a subgroup of patients in whom adaptation of management is warranted.

RESUMO

BACKGROUND AND OBJECTIVES: High rates of recurrence have been observed after curative treatment for hepatocellular carcinoma (HCC). The main aim of this study was to establish the influence of adjuvant transarterial radioembolization-based I-131 lipiodol on survival and recurrence. METHODS: Between 2004 and 2010, 38 patients were treated with adjuvant I-131 lipiodol therapy, at a dosage of 2220 MBq, within 4 months after surgery. This treated cohort was compared to a control cohort consisting of 42 consecutive patients operated prior to the time the I-131 lipiodol treatment became available. RESULTS: Recurrence-free survival in the control and in the I-131 lipiodol cohort was 12.6 and 18.7 months, respectively (HR = 1.871, p = 0.025). At 2 and 5 years, the cumulative incidence of a first recurrence or death was, respectively, 50 % and 61 % in the treated cohort versus 69 % and 74 % in the control cohort. Median overall survival was 55 and 29 months, respectively (p = 0.051). Among patients with a recurrence at 2 years, more patients had already experienced such recurrence at 1 year in the control cohort (70 % vs 33 %, p = 0.014). CONCLUSIONS: Adjuvant I-131 lipiodol improves disease-free survival in patients with HCC.

RESUMO

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.

RESUMO

Boceprevir and telaprevir are 2 specific inhibitors of the hepatitis C (HCV) serine protease 3. Cutaneous side effects have been reported with high frequency, essentially rash, and dry skin. We report a case of drug rash with eosinophilia and systemic symptoms (DRESS) due to boceprevir. A 56-year-old African woman with chronic hepatitis C complicated with cirrhosis and cryoglobulinemia received pegylated interferon alfa-2a (PegIFN) and ribavirin (RBV) for 4 weeks and then boceprevir was added. She was also co-infected with HIV state A2. Eight weeks after adding boceprevir she developed a generalized maculopapular exanthema with fever, facial oedema, apparition of lymph node and alteration of the general state. She presented an eosinophilia (up to 3.0 × 10(9)cells/L), no biological inflammatory syndrome. The computed tomography revealed several lymph nodes located in the abdominal and inguinal areas. The cutaneous biopsy was consistent with a drug rash reaction. The HCV treatment was stopped and the patient was treated with topical steroids. Cutaneous and systemic symptoms disappeared in few weeks. Boceprevir was considered the culprit drug. We report to our knowledge the first case of DRESS due to boceprevir.

RESUMO

BACKGROUND: Mortality among patients with severe acute alcoholic hepatitis is high, even among those treated with glucocorticoids. We investigated whether combination therapy with glucocorticoids plus N-acetylcysteine would improve survival. METHODS: We randomly assigned 174 patients to receive prednisolone plus N-acetylcysteine (85 patients) or only prednisolone (89 patients). All patients received 4 weeks of prednisolone. The prednisolone-N-acetylcysteine group received intravenous N-acetylcysteine on day 1 (at a dose of 150, 50, and 100 mg per kilogram of body weight in 250, 500, and 1000 ml of 5% glucose solution over a period of 30 minutes, 4 hours, and 16 hours, respectively) and on days 2 through 5 (100 mg per kilogram per day in 1000 ml of 5% glucose solution). The prednisolone-only group received an infusion in 1000 ml of 5% glucose solution per day on days 1 through 5. The primary outcome was 6-month survival. Secondary outcomes included survival at 1 and 3 months, hepatitis complications, adverse events related to N-acetylcysteine use, and changes in bilirubin levels on days 7 and 14. RESULTS: Mortality was not significantly lower in the prednisolone-N-acetylcysteine group than in the prednisolone-only group at 6 months (27% vs. 38%, P = 0.07). Mortality was significantly lower at 1 month (8% vs. 24%, P = 0.006) but not at 3 months (22% vs. 34%, P = 0.06). Death due to the hepatorenal syndrome was less frequent in the prednisolone-N-acetylcysteine group than in the prednisolone-only group at 6 months (9% vs. 22%, P = 0.02). In a multivariate analysis, factors associated with 6-month survival were a younger age (P<0.001), a shorter prothrombin time (P<0.001), a lower level of bilirubin at baseline (P<0.001), and a decrease in bilirubin on day 14 (P<0.001). Infections were less frequent in the prednisolone-N-acetylcysteine group than in the prednisolone-only group (P = 0.001); other side effects were similar in the two groups. CONCLUSIONS: Although combination therapy with prednisolone plus N-acetylcysteine increased 1-month survival among patients with severe acute alcoholic hepatitis, 6-month survival, the primary outcome, was not improved.

RESUMO

We report the case of a 77-year-old man referred for jaundice and diagnosed with intrahepatic light chain deposit as primary manifestation of a kappa light chain multiple myeloma. Jaundice is a very rare way of presentation for myeloma. In our observation, diagnosis was made by liver biopsy, which found light chain deposits infiltrating perisinusoidal spaces. We discuss jaundice's possible mechanisms in myeloma.

RESUMO

Liver biopsy is considered the gold-standard method for the assessment of liver fibrosis during follow-up of hepatitis C virus-infected patients, but this invasive procedure is not devoid of complications. The aim of the present study was to identify novel non-invasive markers of fibrosis progression. By microarray analysis, we compared transcript levels in two extreme stages of fibrosis from 16 patients. Informative transcripts were validated by real-time PCR and used for the assessment of fibrosis in 23 additional patients. Sixteen transcripts were found to be dysregulated during the fibrogenesis process. Among them, some were of great interest because their corresponding proteins could be serologically measured. Thus, the protein levels of inter-alpha inhibitor H1, serpin peptidase inhibitor clade F member 2, and transthyretin were all significantly different according to the four Metavir stages of fibrosis. In conclusion, we report here that dysregulation, at both the transcriptional and protein levels, exists during the fibrogenesis process. Our description of three novel serum markers and their potential use as serological tests for the non-invasive diagnosis of liver fibrosis open new opportunities for better follow-up of hepatitis C virus-infected patients.

RESUMO

AIMS: Hepatocellular carcinoma (HCC) results from cirrhosis and, in Western Europe, hepatitis C virus and alcoholism are the predominant causes of this disease. We recently documented a global transcript repression in hepatocarcinoma nodules. The tumour suppressor activated pathway-6 (TSAP6) transcript codes for a transmembrane molecule that is an inducer of a caspase-3-dependent apoptotic pathway. The down-regulation of TSAP6 transcripts in HCC and perinodular cirrhosis, which contrasts with a sustained transcript level in HCC-free cirrhosis, has suggested that this hepatic protein level may provide a prognostic marker for HCC occurrence. METHODS AND RESULTS: This protein was quantified by semiquantitative assessment of immunohistochemistry on samples from 42 cases HCC-free cirrhosis, 49 cases cirrhosis with HCC, 43 HCC associated with healthy liver and 31 controls. TSAP6 expression was linked to the liver state, healthy or cirrhotic without or with an HCC and to tumour grade. CONCLUSIONS: With biopsies periodically performed for surveillance purposes, the decreased expression of TSAP6 in cirrhotic tissue could reflect a decrease in the apoptotic process and could be interpreted as a warning sign. This evaluation of the TSAP6 level in cirrhotic liver conveys predictive information for the development of HCC.

RESUMO

AIM: To search for transcription dysregulation that could (1) differentiate hepatocellular carcinoma (HCC)-free from HCC-related cirrhosis (2) differentiate HCC-free cirrhosis related to HCV from that related to alcohol intake. METHODS: Using microarray analysis, we compared transcript levels in HCC-free cirrhosis (alcoholism: 7; hepatitis C: 7), HCC-associated cirrhosis (alcoholism: 10; hepatitis C: 10) and eight control livers. The identified transcripts were validated by qRT-PCR in an independent cohort of 45 samples (20 HCC-free cirrhosis; 15 HCC-associated cirrhosis and 10 control livers). We also confirmed our results by immunohistochemistry. RESULTS: In HCC-free livers, we identified 70 transcripts which differentiated between alcoholic-related cirrhosis, HCV-related cirrhosis and control livers. They mainly corresponded to down-regulation. Dysregulation of Signal Transduction and Activator of Transcription-3 (STAT-3) was found along with related changes in STAT-3 targets which occurred in an etiology-dependent fashion in HCC-free cirrhosis. In contrast, in HCC, such transcription dysregulations were not observed. CONCLUSION: We report that transcriptional dysregulations exist in HCC-free cirrhosis, are transiently observed prior to detectable HCC onset and may be appear like markers from cirrhosis to HCC transition.
