Transjugular Intrahepatic Portosystemic Shunts With Covered Stents Increase Transplant-Free Survival of Patients With Cirrhosis and Recurrent Ascites.

BACKGROUND & AIMS: There is controversy over the ability of transjugular intrahepatic portosystemic shunts (TIPS) to increase survival times of patients with cirrhosis and refractory ascites. The high rate of shunt dysfunction with the use of uncovered stents counteracts the benefits of TIPS. We performed a randomized controlled trial to determine the effects of TIPS with stents covered with polytetrafluoroethylene in these patients. METHODS: We performed a prospective study of 62 patients with cirrhosis and at least 2 large-volume paracenteses within a period of at least 3 weeks; the study was performed at 4 tertiary care centers in France from August 2005 through December 2012. Patients were randomly assigned to groups that received covered TIPS (n = 29) or large-volume paracenteses and albumin as necessary (LVP+A, n = 33). All patients maintained a low-salt diet and were examined at 1 month after the procedure then every 3 months until 1 year. At each visit, liver disease-related complications, treatment modifications, and clinical and biochemical variables needed to calculate Child-Pugh and Model for End-Stage Liver Disease scores were recorded. Doppler ultrasonography was performed at the start of the study and then at 6 and 12 months after the procedure. The primary study end point was survival without a liver transplant for 1 year after the procedure. RESULTS: A higher proportion of patients in the TIPS group (93%) met the primary end point than in the LVP+A group (52%) (P = .003). The total number of paracenteses was 32 in the TIPS group vs 320 in the LVP+A group. Higher proportions of patients in the LVP+A group had portal hypertension-related bleeding (18% vs 0%; P = .01) or hernia-related complications (18% vs 0%; P = .01) than in the TIPS group. Patients in LVP+A group had twice as many days of hospitalization (35 days) as the TIPS group (17 days) (P = .04). The 1-year probability of remaining free of encephalopathy was 65% for each group. CONCLUSIONS: In a randomized trial, we found covered stents for TIPS to increase the proportion of patients with cirrhosis and recurrent ascites who survive transplantation-free for 1 year, compared with patients given repeated LVP+A. These findings support TIPS as the first-line intervention in such patients. ClinicalTrials.gov ID: NCT00222014.

Assessment of adrenal function in cirrhotic patients: salivary cortisol should be preferred.

BACKGROUND & AIMS: Adrenal insufficiency is a common disorder among cirrhotic patients. Adrenal function is usually assessed with serum total cortisol assays. Free cortisol (active fraction) represents only 10% of serum total cortisol, the remaining 90% being linked to cortisol-binding globulin (CBG) and albumin. In cirrhotic patients, the synthesis of these proteins is reduced, which could lead to an overestimation of the prevalence of adrenal insufficiency. Salivary cortisol assessment adequately reflects free cortisol plasma concentration. However, this method has never been validated in cirrhotic patients. The objectives of this report were to assess the following parameters by a prospective observational study: (1) correlation between salivary, serum total and free cortisol, (2) adrenal insufficiency prevalence using salivary and serum assays, (3) parameters associated with a discrepancy between both tests, and (4) adrenal insufficiency risk factors among cirrhotic patients. METHODS: Salivary and serum total cortisol were assessed before and 1h following an injection of corticotropin (250 microg) in patients hospitalized for cirrhosis complications without shock. CBG was measured and free cortisol was assessed by the Coolens formula. RESULTS: Eighty-eight patients were included in the study (Child-Pugh C: 68.2%). Free cortisol was more strongly correlated with salivary than with serum total cortisol (Spearman coefficient=0.91 vs. 0.76, respectively, p<0.001). Among included patients, 9.1% had adrenal insufficiency according to salivary cortisol and 33.0% had adrenal insufficiency according to serum total cortisol (p=0.001). Hypoalbuminemia was the only factor associated with a discrepancy between the results of both tests. Adrenal insufficiency risk factors were ascites and low HDL-cholesterol plasma concentration. CONCLUSION: Using serum total cortisol assays overstate adrenal insufficiency prevalence among cirrhotic patients, mainly because of inaccurate concentrations related to hypoalbuminemia. Salivary cortisol assays should be preferably used in these patients.

Effect on HBs antigen clearance of addition of pegylated interferon alfa-2a to nucleos(t)ide analogue therapy versus nucleos(t)ide analogue therapy alone in patients with HBe antigen-negative chronic hepatitis B and sustained undetectable plasma hepatitis B virus DNA: a randomised, controlled, open-label trial.

BACKGROUND: Findings from uncontrolled studies suggest that addition of pegylated interferon in patients with HBe antigen (HBeAg)-negative chronic hepatitis B receiving nucleos(t)ide analogues with undetectable plasma hepatitis B virus (HBV) DNA might increase HBs antigen (HBsAg) clearance. We aimed to assess this strategy. METHODS: In this randomised, controlled, open-label trial, we enrolled patients aged 18-75 years with HBeAg-negative chronic hepatitis B and documented negative HBV DNA while on stable nucleos(t)ide analogue regimens for at least 1 year from 30 hepatology tertiary care wards in France. Patients had to have an alanine aminotransferase concentration of less than or equal to five times the upper normal range, no hepatocellular carcinoma, and a serum α fetoprotein concentration of less than 50 ng/mL, normal dilated fundus oculi examination, and a negative pregnancy test in women. Patients with contraindications to pegylated interferon were not eligible. A centralised randomisation used computer-generated lists of random permuted blocks of four with stratification by HBsAg titres (< or ≥2·25 log10 IU/mL) to allocate patients (1:1) to receive a 48 week course of subcutaneous injections of 180 µg per week of pegylated interferon alfa-2a in addition to the nucleos(t)ide analogue regimen or to continue to receive nucleos(t)ide analogues only. The primary endpoint was HBsAg loss at week 96 by intention-to-treat analysis. This trial is closed and registered with ClinicalTrials.gov, number NCT01172392. FINDINGS: Between Jan 20, 2011, and July 18, 2012, we randomly allocated 185 patients (92 [50%] to pegylated interferon and nucleos(t)ide analogues and 93 [50%] to nucleos(t)ide analogues alone). We excluded two patients from the pegylated interferon plus nucleos(t)ide analogues group from analyses because of withdrawal of consent (one patient) or violation of inclusion criteria (one patient). At week 96, loss of HBsAg was reported in seven (7·8%) of 90 patients in the pegylated interferon plus nucleos(t)ide analogues group versus three (3·2%) of 93 in the nucleos(t)ide analogues-alone group (difference 4·6% [95% CI -2·6 to 12·5]; p=0·15). 85 (94%) of 90 patients started pegylated interferon, three (4%) of whom had a dose reduction and 17 (20%) had an early discontinuation of pegylated interferon (seven [41%] for serious adverse events). Grade 3 and 4 adverse events were more frequent in the pegylated interferon plus nucleos(t)ide analogues group (26 [29%] grade 3 adverse events; 19 [21%] grade 4 adverse events) than in the nucleos(t)ide analogues-alone group (three [3%] grade 3; six [6%] grade 4). INTERPRETATION: Addition of a 48 week course of pegylated interferon to nucleos(t)ide analogue therapy in patients with HBeAg-negative chronic hepatitis B with undetectable HBV DNA for a least 1 year was poorly tolerated and did not result in a significant increase of HBsAg clearance.

Management of gastric varices: a French national survey.

BACKGROUND AND AIMS: Bleeding from gastric varices is more severe than that from esophageal varices, but its management remains debated. We aimed to determine how French hepatogastroenterologists manage cirrhotic patients with gastric varices. METHODS: Hepatogastroenterologists (n=1163) working in general or university hospitals received a self-administered questionnaire. RESULTS: Overall, 155 hepatogastroenterologists (13.3%) from 112 centers (33.3%; 39/40 university hospitals, 73/296 general hospitals) answered. Primary prophylaxis was used by 98.1% of hepatogastroenterologists as follows: ß-blockers 96.1% (93.8 vs. 97.0%; university vs. general hospitals respectively; P=0.57), glue obliteration 16.9% (17.2 vs. 16.3%; P=0.88), and transjugular intrahepatic portosystemic shunt (TIPS) 8.0% (12.7 vs. 4.6%; P=0.12). To manage bleeding, university hospitals had greater local access to glue obliteration (95.4 vs. 68.2%; P<0.001) and TIPS (78.5 vs. 3.5%; P<0.001). Early TIPS was proposed by 53.6% (72.1 vs. 39.2%; P<0.001). Glue obliteration was performed under general anesthesia (86.1%) using Glubran (43.1%) or Histoacryl (52.9%), and lipiodol (78.8%) with varying degrees of dilution (1 : 10 to 3 : 4). The injected volume per varix varied widely (1-20 ml). Glue obliteration, band ligation, or both were used by, respectively, 64.2, 18.2, and 17.5% of practitioners. Almost all hepatogastroenterologists (98%) performed secondary prophylaxis: ß-blockers 74.7% (75.0 vs. 74.4%, university vs. general hospitals; P=0.93), glue obliteration 66.0% (76.9 vs. 57.6%; P=0.013), and TIPS 30.0% (39.1 vs. 23.3%; P=0.037). CONCLUSION: The management of gastric varices in France is heterogeneous across centers. University hospitals have better access to techniques such as glue obliteration and TIPS. As bleeding from gastric varices has a poor outcome, guidelines should be established to standardize clinical practices and design further studies.

Daclatasvir vs telaprevir plus peginterferon alfa/ribavirin for hepatitis C virus genotype 1.

AIM: To evaluate daclatasvir vs telaprevir, each combined with peginterferon alfa-2a/ribavirin (pegIFN/RBV), in treatment-naive hepatitis C virus (HCV) genotype (GT) 1-infected patients. METHODS: In this phase 3, randomized, open-label, noninferiority study, 602 patients were randomly assigned (2:1) to daclatasvir vs telaprevir, stratified by IL28B rs12979860 host genotype (CC vs non-CC), cirrhosis status (compensated cirrhosis vs no cirrhosis), and HCV GT1 subtype (GT1a vs GT1b). Patients were selected by study inclusion criteria from a total of 793 enrolled patients. Patients received daclatasvir 60 mg once daily or telaprevir 750 mg 3 times daily plus pegIFN/RBV. Daclatasvir recipients received 24 wk of daclatasvir plus pegIFN/RBV; those without an extended rapid virologic response (eRVR; undetectable HCV-RNA at weeks 4 and 12) received an additional 24 wk of pegIFN/RBV. Telaprevir-treated patients received 12 wk of telaprevir plus pegIFN/RBV followed by 12 (with eRVR) or 36 (no eRVR) wk of pegIFN/RBV. The primary objective was to compare for noninferiority of sustained virologic response rates at posttreatment week 12 (SVR12) in GT1b-infected patients. Key secondary objectives were to demonstrate that the rates of anemia (hemoglobin < 10 g/dL) and rash-related events, through week 12, were lower with daclatasvir + pegIFN/RBV than with telaprevir + pegIFN/RBV among GT1b-infected patients. Resistance testing was performed using population-based sequencing of the NS5A region for all patients at baseline, and for patients with virologic failure or relapse and HCV-RNA ≥ 1000 IU/mL, to investigate any link between NS5A polymorphisms associated with daclatasvir resistance and virologic outcome. RESULTS: Patient demographics and disease characteristics were generally balanced across treatment arms; however, there was a higher proportion of black/African Americans in the daclatasvir groups (6.0% and 8.2% in the GT1b and GT1a groups, respectively) than in the telaprevir groups (2.2% and 3.0%). Among GT1b-infected patients, daclatasvir plus pegIFN/RBV was noninferior to telaprevir plus pegIFN/RBV for SVR12 [85% (228/268) vs 81% (109/134); difference, 4.3% (95%CI: -3.3% to 11.9%)]. Anemia (hemoglobin < 10 g/dL) was significantly less frequent with daclatasvir than with telaprevir [difference, -29.1% (95%CI: -38.8% to -19.4%)]. Rash-related events were also less common with daclatasvir than with telaprevir, but the difference was not statistically significant. In GT1a-infected patients, SVR12 was 64.9% with daclatasvir and 69.7% with telaprevir. Among both daclatasvir and telaprevir treatment groups, across GT1b- or GT1a-infected patients, lower response rates were observed in patients with IL28B non-CC and cirrhosis - factors known to affect response to pegIFN/RBV. Consistent with these observations, a multivariate logistic regression analysis in GT1b-infected patients demonstrated that SVR12 was associated with IL28B host genotype (CC vs non-CC, P = 0.011) and cirrhosis status (absent vs present, P = 0.031). NS5A polymorphisms associated with daclatasvir resistance (at L28, R30, L31, or Y93) were observed in 17.3% of GT1b-infected patients at baseline; such variants did not appear to be absolute predictors of failure since 72.1% of these patients achieved SVR12 compared with 86.9% without these polymorphisms. Among GT1b-infected patients, treatment was completed by 85.4% (229/268) in the daclatasvir group, and by 85.1% (114/134) in the telaprevir group, and among GT1a-infected patients, by 67.2% (90/134) and 69.7% (46/66), respectively. Discontinuations (of all 3 agents) due to an AE were more frequent with telaprevir than with daclatasvir, whereas discontinuations due to lack of efficacy were more frequent with daclatasvir, due, in part, to differences in futility criteria. CONCLUSION: Daclatasvir plus pegIFN/RBV demonstrated noninferiority to telaprevir plus pegIFN/RBV for SVR12 and was well-tolerated in treatment-naive GT1b-infected patients, supporting the use of daclatasvir with other direct-acting antivirals.
