Objective. Intramural hematoma of the small intestine is a complication of anticoagulant treatment with an estimated incidence of 1 case per 2500 anticoagulated patients per year. Patients may present with signs of small bowel obstruction or, in case of a ruptured hematoma, with upper gastrointestinal tract hemorrhage and hypovolemic shock. Material and methods. Case report and review of the literature. Results. We present a case of a 73-year-old male who was referred for a protruding mass in the duodenum and subsequently developed hematemesis and melena caused by a ruptured hematoma of the duodenal wall. Conclusions. Although intramural hematoma of the duodenum is a rare complication of anticoagulant therapy, early diagnosis with subsequent correction of coagulation parameters is of vital importance.

Background: Clinical outcomes of chronic hepatitis C infection in patients with advanced fibrosis include liver failure, hepatocellular carcinoma, and death. Objective: To investigate whether sustained virologic response to treatment for hepatitis C is associated with improved clinical outcomes. Design: Retrospective cohort study. Setting: 5 hepatology units of tertiary care centers in Europe and Canada caring for patients with chronic hepatitis C treated between 1990 and 2003. Patients: Consecutively treated patients with chronic hepatitis C who had biopsy-proven advanced fibrosis or cirrhosis (Ishak score, 4 to 6). Measurements: Sustained virologic response, defined as absence of detectable hepatitis C virus RNA at 24 weeks after the end of treatment, and clinical outcomes, defined as death (liver-related or non—liver-related), liver failure, and hepatocellular carcinoma. Results: Of 479 patients, 29.6% had sustained virologic response and 70.3% did not. Median follow-up was 2.1 years (interquartile range, 0.8 to 4.9 years). Four patients with and 83 without sustained virologic response had at least 1 outcome event. Sustained virologic response was associated with a statistically significant reduction in the hazard of events (adjusted hazard ratio, 0.21 [95% CI, 0.07 to 0.58]; P = 0.003). The effect was largely attributable to a reduction in liver failure, which developed in no patients with and 42 patients without sustained virologic response (5-year occurrence, 0% vs. 13.3% [CI, 8.4% to 18.2%]; unadjusted hazard ratio, 0.03 [CI, 0.00 to 0.91]). Limitations: Because few events occurred in the sustained virologic response group, the study had limited ability to detect differences between groups in individual outcomes. In addition, the study was retrospective; selection and survival biases may therefore influence estimates of effect. Conclusion: Sustained virologic response to treatment is associated with improved clinical outcomes, mainly prevention of liver failure, in patients with chronic hepatitis C and advanced fibrosis.

Background/Aims: The glycosphingolipid α-galactosylceramide has been shown to activate invariant natural killer T cells when presented in the context of CD1d and induces powerful antiviral immune responses via the production of inflammatory cytokines. The aim of this study was to investigate the safety and the antiviral activity of α-galactosylceramide as a novel class of treatment for chronic hepatitis C patients. Methods: International multicenter dose-escalating randomized placebo-controlled phase I/II trial. Results: Forty patients were allocated to a dose of 0.1μg/kg (n =9), 1μg/kg (n =9), 10μg/kg (n =11) or to placebo (n =11). α-Galactosylceramide was well tolerated and no patients were withdrawn due to side effects. Although most patients showed a decrease in invariant natural killer T cells after administration, no clinically relevant suppression of viral replication was observed. Only one patient, a previous non-responder to peginterferon and ribavirin with high baseline invariant natural killer T cell levels, showed profound signs of immune activation, accompanied by a transient 1.3 log decrease in HCV-RNA and a concomitant increase in ALT after the first administration. Conclusions: α-Galactosylceramide used as monotherapy for interferon-refractory patients in doses of 0.1–10μg/kg is safe and it exerts moderate immunomodulatory effects. However, in its current form it has no significant effect on HCV-RNA levels. [Copyright &y& Elsevier]

- Abstract
Objective. Patients with chronic hepatitis C who do not respond to interferon can be treated with glycyrrhizin to reduce disease activity. The objective of this study was to evaluate the effect of glycyrrhizin on the incidence of hepatocellular carcinoma (HCC) during long-term follow-up after non-response to interferon. Material and methods. We analyzed individual patient data of all consecutive patients treated with interferon in 12 major Japanese hospitals between 1990 and 1995 who showed no sustained response. Results. The study comprised 1093 patients. During a mean follow-up of 6.1±1.8 years, 107 patients developed HCC. The Cox regression analysis with time-dependent variables showed that older age, male gender, higher alanine aminotransferase (ALAT) and higher fibrosis stage were significantly associated with a higher risk of developing HCC. Response to glycyrrhizin, defined as ALAT < 1.5×upper limit of normal, was significantly associated with a decreased incidence of HCC: hazard ratio 0.39 (95% CI 0.21–0.72; p<0.01). G-estimation, used to correct for ALAT as the confounder, showed no significant benefit of glycyrrhizin in the overall study population. Conclusions. This study provides some evidence to show that interferon non-responder patients with chronic hepatitis C and fibrosis stage 3 or 4 may have a reduced incidence of HCC if glycyrrhizin therapy leads to normalization of ALAT levels.

HEPATITIS C , *INTERFERONS , *PLACEBOS , *RIBAVIRIN , *RANDOMIZED controlled trials - Abstract
Background: Evidence based medicine depends on unbiased selection of completed randomized controlled trials. For completeness it is important to publish all trials. This report describes the first large randomised controlled trial where combination therapy was compared to placebo therapy and to ribavirin monotherapy, which has not been published untill now. Methods: One hundred and twenty one patients with chronic hepatitis C and elevated transaminases who did not respond to previous treatment with standard interferon monotherapy, were included from 16 centers in Belgium, the Netherlands and Luxembourg between 1992 and 1996. Patient poor-response characteristics were: genotype 1 (69%), HCV RNA above 2 x 106 copies/ml (55%) and cirrhosis (38%). Patients were randomized to 6 months combination therapy with interferon alpha-2b (3 MU tiw) and ribavirin (1000-1200 mg / day), 6 months ribavirin monotherapy (1000-1200 mg / day) or 6 months ribavirin placebo. The study was double blinded for the ribavirin / placebo component. One patient did not fit the entry criteria, and 3 did not start. All 117 patients who received at least one dose of treatment were included in the intention to treat analysis. Results: At the end of treatment, HCV RNA was undetectable in 35% of patients on combination therapy and in none of the patients treated with ribavirin monotherapy or placebo. The sustained virological response rate at 6 months after therapy was 15% for patients treated with interferon and ribavirin. During the 6 months treatment period 13% of patients on interferon ribavirin combination therapy, 13% of patients on ribavirin monotherapy and 11% of patients on placebo withdrew due to side effects or noncompliance. At 24 weeks of treatment the mean Hb level was 85% of the baseline value, which means a mean decrease from 9.1 mmol/l to 7.8 mmol/l. The Hb levels at the end of treatment were not significantly different from patients treated with ribavirin monotherapy (p = 0.76). End of treatment WBC was significantly lower in patients treated with combination therapy, compared to ribavirin (p < 0.01) as well as for patients treated with ribavirin monotherapy compared to placebo (p < 0.01). Discussion: This belated report on the only placebo controlled study of interferon ribavirin combination therapy in non responders to standard doses of interferon monotherapy documents the effectiveness, be it limited, of this approach as well as the dynamics of the effects on blood counts.

Abstract: We describe a patient who presented with loss of vision that turned out to be caused by cobalamin deficiency. Both her vision and her visual field improved upon supplementation of cobalamin. It is, therefore, important to consider cobalamin deficiency as a treatable cause of loss of vision.

CHRONIC hepatitis C , *HEPATIC fibrosis , *CYSTIC fibrosis treatment , *PLATELET count , *SPLENOMAGALY , *THERAPEUTICS - Abstract
Background and Aims: Patients with chronic hepatitis C virus (HCV) infection may develop cirrhosis with portal hypertension, reflected by decreased platelet count and splenomegaly. This retrospective cohort study aimed to assess changes in platelet counts after antiviral therapy among chronic HCV-infected patients with advanced fibrosis. Methods: Platelet counts and spleen sizes were recorded in an international cohort of patients with Ishak 4-6 fibrosis who started antiviral therapy between 1990 and 2003. Last measured platelet counts and spleen sizes were compared with their pre-treatment values (within 6 months prior to the start of therapy). All registered platelet count measurements from 24-week following cessation of antiviral therapy were included in repeated measurement analyses. Results: This study included 464 patients; 353 (76%) had cirrhosis and 187 (40%) attained sustained virological response (SVR). Among patients with SVR, median platelet count, increased by 35 × 109/L (IQR 7-62, P < 0.001). In comparison, patients without SVR showed a median decline of 17 × 109/L (IQR −5-47, P < 0.001). In a subgroup of 209 patients, median decrease in spleen size was 1.0 cm (IQR 0.3-2.0) for patients with SVR, while median spleen size increased with 0.6 cm (IQR −0.1-2.0, P < 0.001) among those without SVR. The changes in spleen size and platelet count were significantly correlated ( R = −0.41, P < 0.001). Conclusions: Among chronic HCV-infected patients with advanced hepatic fibrosis, the platelet counts improved following SVR and the change in platelets correlated with the change in spleen size following antiviral therapy. These results suggest that HCV eradication leads to reduced portal pressure. [ABSTRACT FROM AUTHOR]

CHRONIC hepatitis C , *HEPATIC fibrosis , *ANTIVIRAL agents , *MEDICAL care costs , *INTERFERONS , *THERAPEUTICS - Abstract
Background and Aims Very potent direct acting antivirals for the treatment of chronic hepatitis C virus infection were recently introduced into daily clinical practice. Currently, treatment uptake is hampered by their high costs, eliciting prioritization of treatment. We aimed to evaluate the direct medical costs during interferon (IFN)-based antiviral treatment and the costs per sustained virological response (SVR) among patients with advanced hepatic fibrosis. Methods This retrospective cohort study included all consecutive patients with chronic hepatitis C virus infection and biopsy-proven bridging fibrosis or cirrhosis (Ishak 4-6) treated with IFN-based regimens in five hepatology units of tertiary care centers in Europe and Canada. Direct medical costs, expressed in 2013 Euros, during therapy were assessed. The components of care were quantified by three distinct categories: treatment, safety/ monitoring, and complications. Cost per SVR was calculated by dividing the mean cost by the SVR rate. Results In total, 672 interferon-based treatments administered to 455 patients were included. Total medical costs per patient were averaged to €14 559 (95% confidence interval [CI], €13 323-€15 836). The mean cost per SVR was €38 514 (95% CI, €35 244-€41 892). The costs per SVR were €26 105 (95% CI, €23 068-€29 296) for patients with a normal platelet count and €50 907 (95% CI, €44 151-€59 612) for patients with thrombocytopenia, with the costs per SVR of €74 961 (95% CI, €55 463-€103 541) among those patients with a platelet count below 100 * 109/L. Conclusions Because of the lower SVR rates, the cost per SVR of IFN-based treatment increased when patients with more advanced liver disease were treated. Additional costs of IFN-free therapy could be limited among these patients. [ABSTRACT FROM AUTHOR]

Background/Objective: Genetic polymorphisms in the inosine triphosphatase (ITPA) gene have been associated with the protection from early ribavirin(RBV)-induced hemolytic anemia among patients with chronic hepatitis C virus (HCV) infection. The aim of the present study was to investigate the association between the functional ITPA variants and hematological side effects during antiviral therapy with pegylated interferon (PegIFN) and RBV. Patients and Methods: This cohort study included all consecutive Caucasian patients treated for chronic HCV infection with PegIFN and RBV between 2000 and 2009 for whom a serum sample was available for genetic testing. The predicted inosine triphosphate pyrophosphatase (ITPase) activity was based on the genotypes of the SNPs rs1127354 and rs7270101. Decline in hemoglobin (Hb) during antiviral therapy, as well as dose reductions, blood transfusions and use of erythropoietin were assessed. Results: In total, 213 patients were included. The predicted ITPase activity was normal among 152 (71%) patients; 61 (29%) patients had ITPase deficiency. By multivariable linear regression, RBV dose in mg per kilogram (Beta 0.09, 95%CI 0.04–0.13, p<0.001) and normal ITPase activity (Beta 0.89, 95%CI 0.64–1.14, p<0.001) were associated with more Hb decline at week 4 of treatment. Patients with normal ITPase activity underwent more dose adjustments of RBV than patients with ITPase deficiency (19(13%) vs 1(2%),p = 0.014) and received erythropoietin more frequently (12 (8%) vs 0 (0%),p = 0.024). Conclusion: Genetic variants in the ITPA gene protected against RBV treatment-induced anemia among Caucasian patients with chronic HCV infection. Patients with normal ITPase activity underwent more dose reductions of RBV and received erythropoietin more frequently. [ABSTRACT FROM AUTHOR]

Background & Aim Pegylated interferon-based treatment is still the backbone of current hepatitis C therapy and is associated with bone marrow suppression and an increased risk of infections. The aim of this retrospective cohort study was to assess the risk of infections during interferon-based treatment among patients with chronic hepatitis C virus ( HCV) infection and advanced hepatic fibrosis and its relation to treatment-induced neutropenia. Methods This cohort study included all consecutive patients with chronic HCV infection and biopsy-proven bridging fibrosis or cirrhosis ( Ishak 4-6) who started treatment between 1990 and 2003 in five large hepatology units in Europe and Canada. Neutrophil counts between 500-749/μL and below 500/μL were considered as moderate and severe neutropenia, respectively. Results This study included 723 interferon-based treatments, administered to 490 patients. In total, 113 infections were reported during 88 (12%) treatments, of which 24 (21%) were considered severe. Only one patient was found to have moderate neutropenia and three patients were found to have severe neutropenia at the visit before the infection. Three hundred and twelve (99.7%) visits with moderate neutropenia and 44 (93.6%) visits with severe neutropenia were not followed by an infection. Multivariable analysis showed that cirrhosis (odds ratio [ OR] 2.85, 95% confidence interval [ CI] 1.38-5.90, P = 0.005) and severe neutropenia at the previous visit ( OR 5.42, 95% CI 1.34-22.0, P = 0.018) were associated with the occurrence of infection, while moderate neutropenia was not. Among a subgroup of patients treated with pegylated interferon, severe neutropenia was not significantly associated ( OR 1.63, 95% CI 0.19-14.2, P = 0.660). Conclusions In this large cohort of patients with bridging fibrosis and cirrhosis, infections during interferon-based therapy were generally mild. Severe interferon-induced neutropenia rarely occurred, but was associated with on-treatment infection. Moderate neutropenia was not associated with infection, suggesting that current dose reduction guidelines might be too strict. [ABSTRACT FROM AUTHOR]

Objective Reliable tools to predict long-term outcome among patients with well compensated advanced liver disease due to chronic HCV infection are lacking. Design Risk scores for mortality and for cirrhosis-related complications were constructed with Cox regression analysis in a derivation cohort and evaluated in a validation cohort, both including patients with chronic HCV infection and advanced fibrosis. Results In the derivation cohort, 100/405 patients died during a median 8.1 (IQR 5.7-11.1) years of follow-up. Multivariate Cox analyses showed age (HR=1.06, 9 5% CI 1.04 to 1.09, p<0.001), male sex (HR=1.91, 95% CI 1.10 to 3.29, p=0.021), platelet count (HR=0.91, 95% CI 0.87 to 0.95, p<0.001) and log10 aspartate aminotransferase/alanine aminotransferase ratio (HR=1.30, 9 5% CI 1.12 to 1.51, p=0.001) were independently associated with mortality (C statistic=0.78, 95% CI 0.72 to 0.83). In the validation cohort, 58/296 patients with cirrhosis died during a median of 6.6 (IQR 4.4 - 9.0) years. Among patients with estimated 5-year mortality risks < 5%, 5 - 10% and >10%, the observed 5-year mortality rates in the derivation cohort and validation cohort were 0 . 9% (95% CI 0.0 to 2.7) and 2.6% (95% CI 0.0 to 6.1), 8.1% (95% CI 1.8 to 14.4) and 8.0% (95% CI 1.3 to 14.7), 21.8% (95% CI 13.2 to 30.4) and 20.9% (95% CI 13.6 to 28.1), respectively (C statistic in validation cohort = 0.76, 9 5% CI 0.69 to 0.83). The risk score for cirrhosis-related complications also incorporated HCV genotype (C statistic = 0.80, 95% CI 0.76 to 0.83 in the derivation cohort; and 0.74, 95% CI 0.68 to 0.79 in the validation cohort). Conclusions Prognosis of patients with chronic HCV infection and compensated advanced liver disease can be accurately assessed with risk scores including readily available objective clinical parameters.

Pegylated interferon is still the backbone of hepatitis C treatment and may cause thrombocytopenia, leading to dose reductions, early discontinuation, and eventually worse clinical outcome. We assessed associations between interferon-induced thrombocytopenia and bleeding complications, interferon dose reductions, early treatment discontinuation, as well as SVR and long-term clinical outcome. Methods All consecutive patients with chronic HCV infection and biopsy-proven advanced hepatic fibrosis (Ishak 4-6) who initiated interferon-based therapy between 1990 and 2003 in 5 large hepatology units in Europe and Canada were included. Results Overall, 859 treatments were administered to 546 patients. Baseline platelets (in 109/L) were normal (⩾150) in 394 (46%) treatments; thrombocytopenia was moderate (75-149) in 324 (38%) and severe (<75) in 53 (6%) treatments. Thrombocytopenia-induced interferon dose reductions occurred in 3 (1%); 46 (16%), and 15 (30%) treatments respectively (p<0.001); interferon was discontinued due to thrombocytopenia in 1 (<1%), 8 (3%), and in 8 (16%) treatments respectively (p<0.001). In total, 104 bleeding events were reported during 53 treatments. Only two severe bleeding complications occurred. Multivariate analysis showed that cirrhosis and a platelet count below 50 were associated with on-treatment bleeding. Within thrombocytopenic patients, patients attaining SVR had a lower occurrence of liver failure (p<0.001), hepatocellular carcinoma (p<0.001), liver related death or liver transplantation (p<0.001), and all-cause mortality (p=0.001) compared to patients without SVR. Conclusions Even in thrombocytopenic patients with chronic HCV infection and advanced hepatic fibrosis, on-treatment bleedings are generally mild. SVR was associated with a marked reduction in cirrhosis-related morbidity and mortality, especially in patients with baseline thrombocytopenia. [ABSTRACT FROM AUTHOR]

- Abstract
Context: Chronic hepatitis C virus (HCV) infection outcomes include liver failure, hepatocellular carcinoma (HCC), and liver-related death.Objective: To assess the association between sustained virological response (SVR) and all-cause mortality in patients with chronic HCV infection and advanced hepatic fibrosis.Design, Setting, and Patients: An international, multicenter, long-term follow-up study from 5 large tertiary care hospitals in Europe and Canada of 530 patients with chronic HCV infection who started an interferon-based treatment regimen between 1990 and 2003, following histological proof of advanced hepatic fibrosis or cirrhosis (Ishak score 4-6). Complete follow-up ranged between January 2010 and October 2011.Main Outcome Measures: All-cause mortality. Secondary outcomes were liver failure, HCC, and liver-related mortality or liver transplantation.Results: The 530 study patients were followed up for a median (interquartile range [IQR]) of 8.4 (6.4-11.4) years. The baseline median (IQR) age was 48 (42-56) years and 369 patients (70%) were men. The Ishak fibrosis score was 4 in 143 patients (27%), 5 in 101 patients (19%), and 6 in 286 patients (54%). There were 192 patients (36%) who achieved SVR; 13 patients with SVR and 100 without SVR died (10-year cumulative all-cause mortality rate, 8.9% [95% CI, 3.3%-14.5%] with SVR and 26.0% [95% CI, 20.2%-28.4%] without SVR; P < .001). In time-dependent multivariate Cox regression analysis, SVR was associated with reduced risk of all-cause mortality (hazard ratio [HR], 0.26; 95% CI, 0.14-0.49; P < .001) and reduced risk of liver-related mortality or transplantation (HR, 0.06; 95% CI, 0.02-0.19; P < .001), the latter occurring in 3 patients with SVR and 103 without SVR. The 10-year cumulative incidence rate of liver-related mortality or transplantation was 1.9% (95% CI, 0.0%-4.1%) with SVR and 27.4% (95% CI, 22.0%-32.8%) without SVR (P < .001). There were 7 patients with SVR and 76 without SVR who developed HCC (10-year cumulative incidence rate, 5.1%; 95% CI, 1.3%-8.9%; vs 21.8%; 95% CI, 16.6%-27.0%; P < .001), and 4 patients with SVR and 111 without SVR experienced liver failure (10-year cumulative incidence rate, 2.1%; 95% CI, 0.0%-4.5%; vs 29.9%; 95% CI, 24.3%-35.5%; P < .001).Conclusion: Among patients with chronic HCV infection and advanced hepatic fibrosis, sustained virological response to interferon-based treatment was associated with lower all-cause mortality.
