RESUMO

BACKGROUND: Nutritional factors are suggested to influence the incidence and severity of glandular gastric disease (GGD) in horses. OBJECTIVES: To retrospectively assess whether dietary fermentable carbohydrates increase the severity of GGD and to prospectively evaluate whether the partial substitution of concentrates by dehydrated alfalfa would decrease GGD severity scores. ANIMALS: In total, 82 trotters from 4 training centers exercised ≥5 days/week. METHODS: Multicenter retrospective observational study, and prospective 2-arm randomized trial. Glandular mucosae were observed by gastroscopy and scored (0-4 severity scale) at day 0 (D0). Biochemical composition of the diet fed was compared between ulcerated and nonulcerated groups. After D0, horses either received the same diet (control, n = 41) or pelleted dehydrated alfalfa substituting 50% concentrates (alfalfa, n = 41). Glandular scores were recorded in both groups after 21 (D21) and 42 days (D42). The first end point was a successful outcome, defined as a horse with a glandular score of 2 to 4 on D0, decreasing to a score of 0 to 1 on days 21 or 42. RESULTS: Horses scored 0 to 1 at D0 ingested more (P = .01) soluble sugars from concentrates than those scored 2 to 4 before D0 (77.5 g/kg BW; 95% confidence interval [CI]: 71.1-84.0, vs 59.1 g/kg BW; 95% CI: 48.0-70.3), whereas starch intake did not differ between groups (P = .24). Among horses scored 2 to 4 at D0, fewer were scored 2 to 4 in the alfalfa group (1 out of 6) compared with the control group (6 out of 6) at D42 (P = .02). Clinical success was 47.7 times more likely in horses fed alfalfa compared with horses in the control group (95% CI: 1.6-1422.8). CONCLUSION AND CLINICAL IMPORTANCE: Relationships were found between diet composition and integrity of the glandular mucosa. Feeding pelleted dehydrated alfalfa could help to reduce the incidence and severity of GGD.

RESUMO

BACKGROUND: Hepatocellular carcinoma is a frequent consequence of alcohol-related liver disease, with variable incidence among heavy drinkers. We did a genome-wide association study (GWAS) to identify common genetic variants for alcohol-related hepatocellular carcinoma. METHODS: We conducted a two-stage case-control GWAS in a discovery cohort of 2107 unrelated European patients with alcohol-related liver disease aged 20-92 years recruited between Oct 22, 1993, and March 12, 2017. Cases were patients with alcohol-related hepatocellular carcinoma diagnosed by imaging or histology. Controls were patients with alcohol-related liver disease without hepatocellular carcinoma. We used an additive logistic regression model adjusted for the first ten principal components to assess genetic variants associated with alcohol-related hepatocellular carcinoma. We did another analysis with adjustment for age, sex, and liver fibrosis. New candidate associations (p<1 × 10-6) and variants previously associated with alcohol-related hepatocellular carcinoma were evaluated in a validation cohort of 1933 patients with alcohol-related liver disease aged 29-92 years recruited between July 21, 1995, and May 2, 2019. We did a meta-analysis of the two case-control cohorts. FINDINGS: The discovery cohort included 775 cases and 1332 controls. Of 7 962 325 variants assessed, we identified WNT3A-WNT9A (rs708113; p=1·11 × 10-8) and found support for previously reported regions associated with alcohol-related hepatocellular carcinoma risk at TM6SF2 (rs58542926; p=6·02 × 10-10), PNPLA3 (rs738409; p=9·29 × 10-7), and HSD17B13 (rs72613567; p=2·49 × 10-4). The validation cohort included 874 cases and 1059 controls and three variants were replicated: WNT3A-WNT9A (rs708113; p=1·17 × 10-3), TM6SF2 (rs58542926; p=4·06 × 10-5), and PNPLA3 (rs738409; p=1·17 × 10-4). All three variants reached GWAS significance in the meta-analysis: WNT3A-WNT9A (odds ratio 0·73, 95% CI 0·66-0·81; p=3·93 × 10-10), TM6SF2 (1·77, 1·52-2·07; p=3·84×10-13), PNPLA3 (1·34, 1·22-1·47; p=7·30 × 10-10). Adjustment for clinical covariates yielded similar results. We observed an additive effect of at-risk alleles on alcohol-related hepatocellular carcinoma. WNT3A-WNT9A rs708113 was not associated with liver fibrosis. INTERPRETATION: WNT3A-WNT9A is a susceptibility locus for alcohol-related hepatocellular carcinoma, suggesting an early role of the Wnt-ß-catenin pathway in alcohol-related hepatocellular carcinoma carcinogenesis.

RESUMO

BACKGROUND: Disturbances in fatty acid (FA) metabolism have been reported in cirrhosis, but the role of FAs in the development of hepatocellular carcinoma (HCC) is still unclear. Biomarkers are a promising means to explore the associations between exogenous intake or endogenous production of FAs and cancer risk. AIM: To estimate the relationship between fatty acid content in erythrocyte membranes and HCC risk in cirrhotic patients METHODS: The "CiRCE" case-control study recruited cirrhotic patients from six French hospitals between 2008 and 2012. Cases were cirrhotic patients with HCC (n = 349); controls were cirrhotic patients without HCC at inclusion (n = 550). FA composition of phospholipids in erythrocyte membranes was determined by high performance gas chromatography. Odds ratios for HCC risk according to FA concentrations were estimated with multivariable logistic regression. RESULTS: HCC patients were older and more often men (P < 0.001). In both groups, saturated FAs represented more than 39% of all FAs in erythrocyte membranes, mono-unsaturated FAs around 14%, and polyunsaturated FAs around 46%. High levels of C15:0 + C17:0, C20:1 n-9, C18:2 n-6 and C20:2 n-6 were associated with higher risk of HCC. The levels of C18:0 and C20:4 n-6 were lower in HCC cases than in controls. CONCLUSIONS: The FA composition of erythrocyte membranes differed according to the presence of HCC with higher levels of saturated FAs, linoleic and eicosadienoic acids, and lower levels of stearic and arachidonic acids. These alterations may reflect particular dietary patterns and/or altered FA metabolism. Further investigations are warranted.

RESUMO

BACKGROUND & AIMS: Short bowel syndrome patients (SBS) receiving parenteral nutrition (PN) often have dyslipidaemia and can develop intestinal failure-associated liver disease (IFALD). These patients demonstrate increased cholesterol synthesis and hepatic lipogenesis. These lipid disturbances may be due to a decreased concentration of the bile acid pool or malabsorption. The aim of this pilot study was to evaluate the effect of bile acid administration on lipid synthesis in patients with SBS. METHODS: The 24 h fractional synthesis rate (FSR) of cholesterol and triglycerides was measured by the isotopic method (deuterated water) before and after 4 months of ursodeoxycholic acid (UDCA) treatment (20 mg/kg/day). Five short bowel patients (age: 53.4 ± 19.2 years) who had normal liver function and lipid plasmatic profiles received 1920 ± 300 ml of PN for 151 ± 74 days (mean PN energy intake was 27.0 ± 6.0 kcal/kg body weight, composed with 3.87 ± 1.38 g/kg of carbohydrate, 0.72 ± 0.25 g/kg of fat and 1.10 ± 0.23 g/kg of amino acids). Plasma metabolites, liver enzymes, 7-α-OH-cholesterol and steatosis levels were also evaluated before and after treatment. Student's t-tests were performed, and the results were expressed in means (±SD). RESULTS: After treatment, decreases in the absolute values of cholesterol synthesis (0.31 ± 0.12 mmol L-1 to 0.24 ± 0.11 mmol L-1; p < 0.05), FSR of cholesterol (31.6 ± 4.7% to 26.4 ± 4.7%; p = 0.06) and FSR of triglycerides (12.8 ± 5.8% to 9.2 ± 5.5%; p < 0.01) were observed. Cholesterol and alanine aminotransferase concentrations also decreased (ALT) (p < 0.05). The absolute values of triglyceride synthesis and triglyceride concentrations remained unchanged. CONCLUSIONS: In SBS patients, UDCA decreases the hepatic synthesis of triglycerides and cholesterol. These results suggest that UDCA could prevent the onset of the IFALD.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Phospholipids are now well-recognised players in tumour progression. Their metabolic tissue alterations can be associated with plasmatic modifications. The aim of this study was to evaluate the potential of the plasma phospholipid profile as a risk and prognostic biomarker in HCC. METHODS: Ninety cirrhotic patients with (cases) or without HCC (controls) were studied after matching for inclusion centre, age, gender, virus infection, cirrhosis duration and Child-Pugh grade. High-performance liquid chromatography coupled with tandem-mass spectrometry was used to quantify the main species of seven categories of phospholipids in plasma. RESULTS: Elevated concentrations of phosphatidylcholine (PC) 16:0/16:1 (p=0.0180), PC 16:0/16:0 (p=0.0327), PC 16:0/18:1 (p=0.0264) and sphingomyelin (SM) 18:2/24:1 (p=0.0379) and low concentrations of lysophosphatidylcholine 20:4 (0.0093) and plasmalogen-phosphatidylethanolamine (pPE) 16:0/20:4 (p=0.0463), pPE 18:0/20:4 (p=0.0077), pPE 18:0/20:5 (p=0.0163), pPE 18:0/20:3 (p=0.0463) discriminated HCC patients from cirrhotic controls. Two ceramide species were associated with increased HCC risk of death while lysophospholipids, a polyunsaturated phosphatidylinositol, some PC and SM species were associated with low risk of death in HCC patients in 1 and/or 3 years. CONCLUSION: This study identified phospholipid profiles related to HCC risk in liver cirrhotic patients and showed for the first time the potential of some phospholipids in predicting HCC patient mortality.

RESUMO

Eighty percent of hepatocellular carcinoma (HCC) cases occur after cirrhosis from various etiologies. The association between diet and cancer is well accepted, but the links with cirrhosis progression and HCC risk have been poorly investigated. However, we hypothesized that diet could be a modifiable preventive factor for HCC. Thus, the aim of our study was to explore the relationships between dietary factors and the risk of HCC in a population of cirrhotic patients. A total of 582 cirrhotic patients were studied: 401 without HCC (controls) and 181 with HCC (cases). These patients were recruited between 2008 and 2012 for the "CiRCE" case-control study conducted in six French university hospitals. Information about the consumption of 208 food items and 23 nutrients were collected through a diet history questionnaire. Unconditional multivariate logistic regressions were performed for each residual food group and nutrients in tertiles. HCC patients were more often men, diabetic and older than controls. After adjustment, a significant positive association was found between HCC risk and carbonated beverages (ORTertile3vsTertile1 = 2.44 [1.17-5.09] p-trend = 0.021), total cereals (ORT3vsT1 = 1.87 [1.09-3.22] p-trend = 0.035), processed meat (ORT3vsT1 = 1.97 [1.14-3.41] p-trend = 0.028) and sodium (ORT3vsT1 = 2.00 [1.14-3.53] p-trend = 0.043). Conversely, the consumption of fiber (ORT3vsT1 = 0.49 [0.28-0.86] p-trend = 0.012), vitamin E (ORT3vsT1 = 0.52 [0.30-0.89] p-trend = 0.017), vitamin B9 (folate and folic acid) (ORT3vsT1 = 0.56 [0.33-0.95] p-trend = 0.036), manganese (ORT3vsT1 = 0.56 [0.32-0.97] p-trend = 0.038) and potassium (ORT3vsT1 = 0.44 [0.25-0.76] p-trend = 0.004) were significantly lower in HCC patients compared with cirrhotic controls. Although these findings must be confirmed in prospective studies, using dietary patterns or biological parameters, they suggest that certain dietary components may modulate HCC risk in cirrhotic patients.

RESUMO

GOALS: The aims of this study were to evaluate whether cytomegalovirus (CMV) infection is associated with hepatocellular carcinoma (HCC) and liver-related mortality in cirrhotic patients. BACKGROUND: In cirrhotic patients, the determinants of HCC and liver-related death are imperfectly known. CMV infection, by its prooncogenic and proinflammatory properties, may favor both the development of HCC and deleterious systemic inflammation. STUDY: In the 1178 patients included between June 2008 and December 2012 in the CIrrhose et Risque de Carcinome Hépatocellulaire dans le grand-Est (CIRCE) study, a French multicenter case-control study designed to identify risk factors of HCC among cirrhotic patients, we identified 432 patients with interpretable CMV serological status at baseline. They included 159 cases with HCC and 273 controls. We measured factors associated with HCC at baseline and subsequent HCC in controls, and predictors of overall and liver-related death in the whole study population. RESULTS: During a median follow-up of 31 months, 25 cases of HCC developed in controls, and 209 deaths (163 liver-related) were recorded. There were 247 (57.2%) CMV-seropositive patients. CMV seropositivity was not associated with more frequent HCC at baseline or during follow-up, but among CMV-positive patients with HCC, the proportion of multinodular, infiltrative, or metastatic tumors at diagnosis was higher (73.8% vs. 57.3%; P=0.029), inducing higher mortality (74% vs. 52% at 3 years; P=0.004). By Cox-regression adjusted for age, gender, Model for End-stage Liver Disease (MELD) score, HCC at baseline, and diabetes, CMV seropositivity independently predicted all-cause (hazard ratio=1.45; 95% confidence interval, 1.08-1.94; P=0.013) and liver-related mortality (hazard ratio=1.56; 95% confidence interval, 1.04-2.30; P=0.031). CONCLUSIONS: In this preliminary study, CMV-seropositive cirrhotic patients were at higher risk of liver-related death caused by more aggressive HCCs or severe cirrhosis complications. These findings warrant confirmation.

RESUMO

Lipid droplet (LD) accumulation is a now well-recognised hallmark of cancer. However, the significance of LD accumulation in colorectal cancer (CRC) biology is incompletely understood under chemotherapeutic conditions. Since drug resistance is a major obstacle to treatment success, we sought to determine the contribution of LD accumulation to chemotherapy resistance in CRC. Here we show that LD content of CRC cells positively correlates with the expression of lysophosphatidylcholine acyltransferase 2 (LPCAT2), an LD-localised enzyme supporting phosphatidylcholine synthesis. We also demonstrate that LD accumulation drives cell-death resistance to 5-fluorouracil and oxaliplatin treatments both in vitro and in vivo. Mechanistically, LD accumulation impairs caspase cascade activation and ER stress responses. Notably, droplet accumulation is associated with a reduction in immunogenic cell death and CD8+ T cell infiltration in mouse tumour grafts and metastatic tumours of CRC patients. Collectively our findings highlight LPCAT2-mediated LD accumulation as a druggable mechanism to restore CRC cell sensitivity.

RESUMO

The molecular mechanisms of hepatocellular carcinoma (HCC) carcinogenesis are still not fully understood. DNA repair defects may influence HCC risk. The aim of the study was to look for potential genetic variants of DNA repair genes associated with HCC risk among patients with alcohol- or viral-induced liver disease. We performed four case-control studies on 2,006 European- (Derivation#1 and #2 studies) and African-ancestry (Validation#1 and #2 studies) patients originating from several cohorts in order to assess the association between genetic variants on DNA repair genes and HCC risk using a custom array encompassing 94 genes. In the Derivation#1 study, the BRIP1 locus reached array-wide significance (Chi-squared SV-Perm, P=5.00×10-4) among the 253 haplotype blocks tested for their association with HCC risk, in patients with viral cirrhosis but not among those with alcoholic cirrhosis. The BRIP1 haplotype block included three exonic variants (rs4986763, rs4986764, rs4986765). The BRIP1 'AAA' haplotype was significantly associated with an increased HCC risk [odds ratio (OR), 2.01 (1.19-3.39); false discovery rate (FDR)-P=1.31×10-2]. In the Derivation#2 study, results were confirmed for the BRIP1 'GGG' haplotype [OR, 0.53 (0.36-0.79); FDR-P=3.90×10-3]. In both Validation#1 and #2 studies, BRIP1 'AAA' haplotype was significantly associated with an increased risk of HCC [OR, 1.71 (1.09-2.68); FDR-P=7.30×10-2; and OR, 6.45 (4.17-9.99); FDR-P=2.33×10-19, respectively]. Association between the BRIP1 locus and HCC risk suggests that impaired DNA mismatch repair might play a role in liver carcinogenesis, among patients with HCV- or HBV-related liver disease.

RESUMO

BACKGROUND & AIM: Several types of unexplained extra-hepatic manifestations, including haematological disorders, have been reported in the context of hepatitis E virus (HEV) infection. However, the underlying mechanism(s) of these manifestations are unknown. We provide evidence that HEV has an extra-hepatic endothelial tropism that can engage cutaneous T cells towards clonality. METHODS: A patient with a CD30(+) cutaneous T cell lymphoproliferative disorder (T-LPD) and biopsy-proven chronic HEV infection received three rounds of oral ribavirin treatment, administered either without or with interferon, and eventually achieved a sustained virologic response (SVR). Pathologic, virologic and immunologic investigations were carried out on biopsied skin lesion, and peripheral blood mononuclear cells between the 2nd and 3rd round of antiviral treatment and biopsied liver. RESULTS: Remission of T-LPD was observed upon antiviral treatment, and the patient remained in complete remission after achieving SVR. The T cell analysis showed large CD30(+) lymphocytes surrounding the blood vessels within the CD8(+) T cell infiltrate. HEV was detected within dermal microvascular endothelial cells using immunofluorescence staining, in situ hybridisation and electron microscopy. Infiltrating T cells mostly comprised memory CD8(+) T cells with a tissue-resident memory T cell phenotype. Overall, 98% of extracted T cells were CD8(+) T cells with aVß signature skewed towards Vß4 and with an oligoclonal profile. T cell clones from T-LPD were more like T cells in the liver than T cells in the blood [odds ratio=4.55, (3.70-5.60), p<0.0001]. No somatic mutations were found in the T-LPD exomes. CONCLUSION: HEV has an extra-hepatic tissue tropism in humans, including dermal endothelium, and can induce CD30(+) T-LPD that is sensitive to antivirals. LAY SUMMARY: Hepatitis E virus (HEV) has an extra-hepatic tissue tropism and should be added to the list of viruses associated with lymphoproliferative disorders. As such, HEV should be part of the laboratory workup of any lymphoproliferation, particularly those of the T cell phenotype that involve the skin. In the context of HEV-associated cutaneous T cell lymphoproliferative disorders, antiviral treatment could be considered a first-line treatment instead of chemotherapy.

RESUMO

OBJECTIVES: The objective of this study was to explore the association between health-related quality of life (HRQoL) and the recommended phase 2 dose in a phase I clinical trial according to the Time to HRQoL deterioration approach (TTD). SETTING: This is a phase I dose-escalation trial of transarterial chemoembolisation (TACE) with idarubicin-loaded beads performed in cirrhotic patients with hepatocellular carcinoma. Patients had to complete the EORTC QLQ-C30 HRQoL questionnaire at baseline and at days 15, 30 and 60 after TACE. PARTICIPANTS: Patients aged ≥18 years with HCC unsuitable for curative treatments were evaluated for the study (N=21). PRIMARY AND SECONDARY OUTCOME MEASUREMENTS: The primary objective was to determine the maximum tolerated dose (MTD) of idarubicin loaded after a single TACE session. MTD was defined as the dose level closest to that causing dose-limiting toxicity in 20% of patients. HRQoL was the secondary end point. RESULTS: Between March 2010 and March 2011, 9, 6 and 6 patients were included at idarubicin dose levels of 5, 10 and 15 mg, respectively. Calculated MTD of idarubicin was 10 mg. At the 10 mg idarubicin dose, patients presented a longer TTD than at 5 mg, for global health status (HR=0.91 (95% CI 0.18 to 4.72)), physical functioning (HR=0.38 (0.04 to 3.22)), fatigue (HR=0.67 (0.18 to 2.56)) and pain (HR=0.47 (0.05 to 4.24)). CONCLUSIONS: These HRQoL results were consistent with the estimated MTD, with a median TTD for global health status of 41 days (21 to NA) at 5 mg, 23 days (20 to NA) at 10 mg and 25 days (17 to NA) at 15 mg. These results show the importance of studying HRQoL in phase I trials. TRIAL REGISTRATION NUMBER: NCT01040559; Post-results.

RESUMO

AIMS: It has recently been shown that an allele in the glucokinase regulatory protein (GCKR) gene was associated with increased liver fat content in obese children. In this study, we set out to determine whether GCKR rs1260326 polymorphism was associated with liver fat content in patients with type 2 diabetes. METHODS: Three hundred and eight patients with type 2 diabetes were included in this study. Liver fat content was evaluated using 1H-MR spectroscopy. RESULTS: In our population, carriers of the rs1260326 minor T allele had a higher liver fat content than did carriers of the C allele homozygote (12.4 ± 9.6 vs. 10.3 ± 9.1 %, p = 0.03). The number of patients with steatosis was significantly higher in minor T allele carriers than in C allele homozygote carriers (70.7 vs. 55.4 %; p = 0.008). In multivariate analysis, the predictive variables for steatosis were BMI [odds ratio (OR) 1.08; 95 % confidence interval (CI) 1.03-1.13; p = 0.002], statin therapy (yes) [OR 0.54; 95 % CI 0.31-0.94; p = 0.03], metformin therapy (yes) [OR 2.67; 95 % CI 1.50-4.75; p < 0.001], and rs1260326 GCKR polymorphism (TT+CT) [OR 1.99; 95 % CI 1.14-3.47; p = 0.01]. CONCLUSIONS: This study shows that in patients with type 2 diabetes who were not selected for liver abnormalities, liver fat content was related to GCKR rs1260326 polymorphism independent of BMI, triglyceride levels, and age.

RESUMO

Ductal plate malformations (DPM) present with a wide phenotypic spectrum comprising Von Meyenburg complexes (VMC), Caroli disease (CD), Caroli syndrome (CS), and autosomal recessive polycystic kidney disease (ARPKD). Variants in PKHD1 are responsible for ARPKD and CS with a high inter- and intra-familial phenotypic variability. Rare familial cases of CD had been reported and exceptional cases of CD are associated with PKHD1 variants. In a family of three siblings presenting with a wide spectrum of severity of DPM, we performed whole exome sequencing and identified two PKHD1 compound heterozygous variants (c.10444G>A; p.Arg3482Cys and c.5521C>T; p.Glu1841Lys), segregating with the symptoms. Two compound heterozygous PKHD1 variants, including one hypomorphic variant, were identified in two other familial cases of DPM with at least one patient presenting with CD. This report widens the phenotypic variability of PKHD1 variants to VMC, and others hepatic bile ducts malformations with inconstant renal phenotype in adults and highlights the important intra-familial phenotypic variability. It also showed that PKHD1 might be a major gene for CD. This work adds an example of the contribution of exome sequencing, not only in the discovery of new genes but also in expanding the phenotypic spectrum of well-known disease-associated genes, using reverse phenotyping.

RESUMO

BACKGROUND & AIMS: Mortality related to hepatitis B virus (HBV) is not well known in developed countries. The aim of this study was to investigate in a population-based cohort the excess risk of death in HBV patients compared with mortality in the general population and to identify risk factors related to all-cause mortality and HBV-related mortality. METHODS: A specialized population-based registry has recorded data from patients with chronic HBV infection in a population of one million inhabitants in France since 1994. Standardized mortality rates for all-cause death and HBV-related death were calculated. Cumulative mortality rates were calculated using the Kaplan-Meier method. Multivariate analysis was performed using a Cox model. RESULTS: Between 1994 and 2009, 1117 people were diagnosed with chronic HBV infection. Of these 136 (12.2%) died. All-cause mortality was significantly higher in HBV-infected people (standardized mortality ratio (SMR) 1.7 [1.4-2.0]). There was substantial excess mortality due to hepatocellular carcinoma (SMR 15.9 [10-24.1]), non-Hodgkin lymphoma (SMR 8.6 [3.1-18.6]) and liver disease (SMR 10.2 [5.8-16.6]). The cumulative rates for all-cause mortality were 8.6% at 5 years, 12.6% at 10 years and 18.5% at 15 years. The corresponding values for HBV-related mortality were 3.5%, 4.2%, and 5.8%. The multivariate analysis for all-cause mortality and for HBV-related mortality showed that male sex, age over 45 at diagnosis, current alcoholism and nosocomial risk factors were predictors of increased mortality. CONCLUSION: This study shows increased all-cause mortality in HBsAg-positive patients, with considerable excess mortality due to chronic liver disease, hepatocellular carcinoma and non-Hodgkin lymphoma.

RESUMO

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is independently associated with atherosclerosis in nondiabetic individuals. In type 2 diabetic patients, the link between fatty liver and atherosclerosis is less clear. Here, we assessed whether liver fat content evaluated using (1)H-magnetic resonance spectroscopy ((1)H-MRS) was independently associated with prevalent carotid plaque as a marker of atherosclerosis in type 2 diabetic patients. METHODS: One hundred and forty-four prospectively enrolled patients with type 2 diabetes underwent liver fat content measurement using (1)H-MRS and carotid plaque assessment using ultrasound. Multiple logistic regressions were used to identify factors associated with carotid plaque. RESULTS: Mean ± SD liver fat content was 9.86±8.12%. Carotid plaque prevalence was 52.1% (75/144). Patients without plaque were younger (P=0.006) and had a smaller visceral fat area (P=0.015), lower reported prevalence of previous cardiovascular events or current statin therapy (P=0.002), and higher liver fat content than those with plaque (P=0.009). By multivariable logistic regression, increased liver fat content independently predicted the absence of carotid plaque [odds ratios (ORs), 0.94; 95% confidence intervals (CIs), 0.89-0.99; P=0.017]. CONCLUSIONS: Liver fat content measured by (1)H-MRS is higher in type 2 diabetic patients without carotid plaque compared to those with plaque. This study suggests that increased liver fat content could be associated with a relative protection against carotid atherosclerosis in patients with type 2 diabetes mellitus.

RESUMO

AIM: This retrospective study aimed to compare the efficacy of and tolerance to two center-related conventional transarterial chemoembolization (TACE) strategies in the management of unresectable hepatocellular carcinoma (HCC). PATIENTS AND METHODS: All HCC patients in whom TACE was initiated in the two centers from June 2008 to July 2011 were included. The TACE strategy performed in center 1 was "on demand" with selective injections of idarubicin, whereas the TACE strategy in center 2 was based "on scheduled" non-selective injections of epirubicin. Toxicity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0. RESULTS: One hundred and fifty HCC patients were included. Median time to treatment failure was significantly higher in center 1, 13.1 months vs. 7.9 months in center 2 (hazard ratio, 2.32; p<10-3 in multivariate analysis). Median overall survival was 21.1 months in center 1 vs. 18.4 months in center 2 (p=NS). The proportion of grade ≥ 3 adverse events and mean hospitalisation duration for the overall TACE treatment were significantly greater in center 2 than in center 1: 56% vs. 32% (p<0.01) and 14.2 ± 7.2 days vs. 10.3 ± 7.0 days (p<0.01), respectively. CONCLUSION: Our results failed to show any significant survival differences between two center-related TACE strategies but showed a significantly smaller proportion of grade ≥ 3 adverse events and shorter hospitalisation for the overall treatment when the "on-demand" strategy was used.

RESUMO

BACKGROUND & AIMS: We investigated the effectiveness of the protease inhibitors peginterferon and ribavirin in treatment-experienced patients with hepatitis C virus (HCV) genotype 1 infection and cirrhosis. METHODS: In the Compassionate Use of Protease Inhibitors in Viral C Cirrhosis study, 511 patients with HCV genotype 1 infection and compensated cirrhosis who did not respond to a prior course of peginterferon and ribavirin (44.3% relapsers or patients with viral breakthrough, 44.8% partial responders, and 8.0% null responders) were given either telaprevir (n = 299) or boceprevir (n = 212) for 48 weeks. We assessed percentages of patients with sustained viral responses 12 weeks after therapy and safety. This observational study did not allow for direct comparison of the 2 regimens. RESULTS: Among patients given telaprevir, 74.2% of relapsers, 40.0% of partial responders, and 19.4% of null responders achieved SVR12. Among those given boceprevir, 53.9% of relapsers, 38.3% of partial responders, and none of the null responders achieved SVR12. In multivariate analysis, factors associated with SVR12 included prior response to treatment response, no lead-in phase, HCV subtype 1b (vs 1a), and baseline platelet count greater than 100,000/mm(3). Severe adverse events occurred in 49.9% of cases, including liver decompensation, severe infections in 10.4%, and death in 2.2%. In multivariate analysis, baseline serum albumin level less than 35 g/L and baseline platelet counts of 100,000/mm(3) or less predicted severe side effects or death. CONCLUSIONS: Relatively high percentages of real-life, treatment-experienced patients with HCV genotype 1 infection and cirrhosis respond to the combination of peginterferon and ribavirin with telaprevir or boceprevir. However, side effects are frequent and often severe. Baseline levels of albumin and platelet counts can be used to guide treatment decisions. ClinicalTrials.gov number: NCT01514890.

RESUMO

BACKGROUND: Transarterial chemoembolisation (TACE) is an effective treatment for unresectable hepatocellular carcinoma (HCC), but can cause severe toxicity. AIM: To identify predictive factors of severe TACE-related toxicity in patients with unresectable HCC. METHODS: All HCC patients who underwent TACE at the Dijon University Hospital between 2008 and 2011 were included in this retrospective study. Severe TACE-related toxicity was defined as the occurrence of any adverse event grade ≥ 4, or any adverse event that caused a prolongation of hospitalisation of >8 days, or any additional hospitalisation within 1 month after TACE. Factors predicting toxicity were identified using a logistic regression model. The robustness of the final model was confirmed using bootstrapping (500 replications). RESULTS: 124 patients were included, median age was 67 years and 90% were male; 22 patients (18%) experienced severe TACE-related toxicity. Factors that independently predicted severe TACE-related toxicity in multivariate analysis were total tumour size (OR, 1.15 cm(-1); 95%CI, 1.04-1.26; p=0.01), and high serum AST levels (OR, 1.10 per 10 IU/l; 95%CI, 1.01-1.21; p=0.04). The results were confirmed by bootstrapping. CONCLUSIONS: Total tumour size and high serum AST levels were predictive factors of severe TACE-related toxicity in this hospital-based series of patients with unresectable HCC.
