Sodium-glucose linked transporter 2 inhibitors in liver cirrhosis: Beyond their antidiabetic use.

Type 2 diabetes mellitus (T2DM) and liver cirrhosis are clinical entities that frequently coexist, but glucose-lowering medication options are limited in cirrhotic patients. Sodium-glucose linked transporter 2 (SGLT2) inhibitors are a class of glucose-lowering medication that act independently of insulin, by causing glycosuria in the proximal convoluted tubule. In this review, we aimed to briefly present the main data and to provide insight into the pathophysiology and potential usefulness of SGLT2 inhibitors in cirrhotic patients with or without T2DM. SGLT2 inhibitors have been proven useful as antidiabetic treatment in patients with metabolic liver disease, with most robust data from patients with metabolic dysfunction-associated steatotic liver disease (MASLD), where they also showed improvement in liver function parameters. Moreover, it has been suggested that SGLT2 inhibitors may have effects beyond their antidiabetic action. Accordingly, they have exhibited cardioprotective effects, expanding their indication in patients with heart failure without T2DM. Since decompensated liver cirrhosis and congestive heart failure share common pathophysiological features, namely renin-angiotensin-aldosterone axis and sympathetic nervous system activation as well as vasopressin secretion, SGLT2 inhibitors could also be beneficial in patients with decompensated cirrhosis, even in the absence of T2DM.

Sedation during endoscopic procedures: a Hellenic Society of Gastroenterology Position Statement.

Administration of sedation by non-anesthesiologists during gastrointestinal endoscopy remains highly controversial in Greece. The aim of this set of 16 position statements prepared by experts in the field on behalf of the Hellenic Society of Gastroenterology is to aid gastroenterologists in their everyday clinical practice and provide evidence for the best use of drugs for the sedation of patients who undergo an endoscopy. The statements address issues such as the level of sedation required, the best drugs used, their mode of action, their side-effects and possible ways to counter their action, and were adopted if at least 80% of all participants agreed upon them.

Serum zonulin levels in patients with liver cirrhosis: Prognostic implications.

BACKGROUND: Increased gut permeability and bacterial translocation play an important role in liver cirrhosis. Zonulin is a recently recognized protein involved in the disintegration of the intestinal barrier. AIM: To investigate possible differences in serum zonulin levels among patients with different cirrhosis stages and their potential prognostic implications. METHODS: Consecutive cirrhotic patients who attended our liver clinic were included in the study. Serum zonulin levels, clinical, radiological and biochemical data were collected at baseline. Patients who accepted participation in a regular surveillance program were followed-up for at least 12 mo. RESULTS: We enrolled 116 cirrhotics [mean Child-Turcotte-Pugh (CTP) score: 6.2 ± 1.6; model for end-stage liver disease score: 11 ± 3.9]. The causes of cirrhosis were viral hepatitis (39%), alcohol (30%), non-alcoholic fatty liver disease (17%), and other (14%). At baseline, 53% had decompensated cirrhosis, 48% had ascites, and 32% had history of hepatic encephalopathy. Mean zonulin levels were significantly higher in patients with CTP-B class than CTP-A class (4.2 ± 2.4 ng/dL vs 3.5 ± 0.9 ng/dL, P = 0.038), with than without ascites (P = 0.006), and with than without history of encephalopathy (P = 0.011). Baseline serum zonulin levels were independently associated with the probability of decompensation at 1 year (P = 0.039), with an area under the receiving operating characteristic of 0.723 for predicting hepatic decompensation. Higher CTP score (P = 0.021) and portal vein diameter (P = 0.022) were independent predictors of mortality. CONCLUSION: Serum zonulin levels are higher in patients with more advanced chronic liver disease and have significant prognostic value in identifying patients who will develop decompensation.

Assessment of dietary habits and the adequacy of dietary intake of patients with cirrhosis-the KIRRHOS study.

BACKGROUND & AIMS: Undernutrition is widely prevalent in patients with cirrhosis and affects prognosis. Given the lack of data regarding the dietary intake (DI) and habits of patients with cirrhosis, the aim of the present study was to evaluate them by assessing diet's adequacy compared to the new guidelines, and the association of DI with nutritional status indicators. METHODS: One hundred and eighty-seven patients (57.8% male, 59.9 ± 10.9 years old, 44.9% decompensated ones) with cirrhosis of various etiologies were enrolled. The patients' DI was assessed using three 24 h recalls, which were analyzed regarding macronutrients' intake, food groups consumption, adherence to the Mediterranean diet and meal patterns. The Goldberg cut-off limits for the ratio of energy intake to resting energy expenditure were used to evaluate dietary underreporting and patients were accordingly classified as low or adequate energy reporters (LERs and AERs). RESULTS: Among the AERs (n = 91, 48.7%) only 29.7% and 31.9% met current recommendations regarding energy and protein intake, accordingly. Patients reported low intake of several healthy food groups and low adherence to the Mediterranean diet. They reported a median of 4.3 eating episodes per day and they frequently omitted late evening snack. Nevertheless, no statistically significant associations were found between parameters of DI and annual and two-year survival. CONCLUSIONS: Low energy reporting was very frequent in this sample of patients with liver cirrhosis. Diet quality was rather poor, whereas energy and protein intakes were lower than those recommended.

Predictive performance of newer Asian hepatocellular carcinoma risk scores in treated Caucasians with chronic hepatitis B.

BACKGROUND & AIMS: Recently, several risk scores for prediction of hepatocellular carcinoma (HCC) were developed in cohorts of treated Asian patients with chronic hepatitis B (CHB), but they have not been assessed in non-Asian patients. We evaluated the predictability and comparative utility of our PAGE-B and recent Asian HCC risk scores in nucleos(t)ide analogue (NA)-treated adult Caucasian patients with CHB, with or without well-documented compensated cirrhosis but not previous diagnosis of HCC. METHODS: We included 1,951 patients treated with entecavir/tenofovir and followed up for a median of 7.6 years. The c-statistic was used to estimate the predictability of PAGE-B, HCC-Rescue, CAMD, mPAGE-B, and AASL score for HCC development within 5 or 10 years. The low- and high-risk group cut-offs were used for estimation of negative (NPV) and positive predictive values (PPV), respectively. RESULTS: HCC developed in 103/1,951 (5.3%) patients during the first 5 years and in another 39/1,428 (2.7%) patients between years 5 and 10. The 3-, 5-, and 10-year cumulative HCC rates were 3.3%, 5.9%, and 9.6%, respectively. All scores offered good 5- and 10-year HCC prediction (c-statistic: 0.78-0.82). NPVs were always >99% (99.3-100%), whereas PPV ranged between 13% and 24%. CONCLUSIONS: In NA-treated Caucasian patients with CHB including compensated cirrhosis, HCC risk scores developed in NA-treated Asian patients offer good 5- and 10-year HCC predictability, similar to that of PAGE-B. PAGE-B and mPAGE-B scores are simpler in clinical practice, as they do not require an accurate diagnosis of cirrhosis, but the addition of albumin in mPAGE-B score does not seem to offer an advantage in patients with well compensated liver disease. LAY SUMMARY: Several risk scores for prediction of hepatocellular carcinoma (HCC) were recently developed in cohorts of treated Asian patients with chronic hepatitis B (CHB). In Caucasian patients with CHB treated with oral antivirals, newer Asian HCC risk scores offer good 5- and 10-year HCC predictability, similar to that of PAGE-B. For clinical practice, PAGE-B and mPAGE-B scores are simpler, as they do not require an accurate diagnosis of cirrhosis.

Similar risk of hepatocellular carcinoma during long-term entecavir or tenofovir therapy in Caucasian patients with chronic hepatitis B.

BACKGROUND & AIMS: A recent study in Asian patients with chronic hepatitis B (CHB) reported that the incidence of hepatocellular carcinoma (HCC) was lower in patients treated with tenofovir disoproxil fumarate (TDF) than entecavir (ETV), but this finding remains controversial. We aimed to identify any differences in HCC incidence, or other patient outcomes, between patients receiving TDF or ETV in the well monitored, multicenter European PAGE-B cohort. METHODS: We included 1,935 Caucasians with CHB, with or without compensated cirrhosis, treated with ETV (n = 772) or TDF (n = 1,163) monotherapy. Mean follow-up was 7.1 ± 3.0 years from ETV/TDF onset. RESULTS: The 5-year cumulative HCC incidence was 5.4% in ETV- and 6.0% in TDF-treated patients (log-rank, p = 0.321), with no significant difference in any patient subgroup (with or without cirrhosis, naïve or experienced to oral antiviral(s) [total, with or without cirrhosis]). In multivariable Cox regression analyses, the hazard of HCC was similar between ETV- and TDF-treated patients after adjustment for several HCC risk factors. ETV- and TDF-treated patients had similar rates of on-therapy biochemical and virological remission, HBsAg loss, liver transplantation and/or death. Elastographic reversion of cirrhosis at year 5 (liver stiffness <12 kPa) was observed in 245/347 (70.6%) patients with pretreatment cirrhosis, being more frequent in TDF- than ETV- treated patients (73.8% vs. 61.5%, p = 0.038). CONCLUSION: In Caucasian patients with CHB, with or without cirrhosis, long-term ETV or TDF monotherapy is associated with similar HCC risk, rates of biochemical/virological remission, HBsAg loss and liver transplantation or death, but elastographic reversion of cirrhosis at year 5 was more frequent with TDF. LAY SUMMARY: In a large cohort of Caucasians with chronic hepatitis B treated with entecavir (ETV) or tenofovir disoproxil fumarate (TDF) monotherapy, cumulative rates of hepatocellular carcinoma did not differ (up to 12 years). Nor did rates of biochemical/virological remission, HBsAg loss and liver transplantation or death. However, elastographic reversion of cirrhosis at year 5 was more frequent in TDF- than ETV-treated patients with pretreatment cirrhosis.

Hepatocellular carcinoma prediction beyond year 5 of oral therapy in a large cohort of Caucasian patients with chronic hepatitis B.

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) may develop in patients with chronic hepatitis (CHB) even after 5 years of oral therapy and cannot be easily predicted. We assessed predictors of HCC development and the need for HCC surveillance in this setting. METHODS: Of 1,951 adult Caucasians with CHB included in the PAGE-B cohort, 1,427 (73%) had completed >5 years of follow-up under therapy without developing HCC by year 5. Median follow-up was 8.4 years from treatment onset. Points-based risk scores were developed to predict HCC risk after year 5. RESULTS: In years 5-12, HCC was diagnosed in 33/1,427 (2.3%) patients with cumulative incidences of 2.4%, 3.2% and 3.8% at 8, 10 and 12 years, respectively. Older age or age >50 years, baseline cirrhosis and liver stiffness (LSM) ≥12 kPa at year 5 were independently associated with increased HCC risk. The HCC incidence was lower in non-cirrhotics than cirrhotics at baseline with year-5 LSM <12; among cirrhotics at baseline, it was lower in those with year-5 LSM <12 than ≥12 kPa. CAGE-B score was based on age at year 5 and baseline cirrhosis in relation to LSM at year 5 and SAGE-B score was based only on age and LSM at year 5 (c-index = 0.809-0.814, 0.805-0.806 after bootstrap validation). Both scores offered 100% negative predictive values for HCC development in their low risk groups. CONCLUSIONS: In Caucasians with CHB, the HCC risk after the first 5 years of antiviral therapy depends on age, baseline cirrhosis status and LSM at year 5. CAGE-B and particularly SAGE-B represent simple and reliable risk scores for HCC prediction and surveillance beyond year 5 of therapy. LAY SUMMARY: In Caucasians with chronic hepatitis B, the risk of hepatocellular carcinoma after the first 5 years of entecavir or tenofovir therapy depends on age, baseline cirrhosis status and liver stiffness at year 5, which can provide simple and reliable risk scores for hepatocellular carcinoma prediction and surveillance beyond year 5. In patients with cirrhosis at baseline, liver stiffness <12 kPa at year 5 is associated with lower HCC risk, but surveillance may be still required.

High prevalence of asymptomatic peptic ulcers diagnosed during screening endoscopy in patients with cirrhosis.

BACKGROUND: Peptic ulcer disease (PUD) is more prevalent in cirrhotics and this may aggravate prognosis. We investigated the prevalence of PUD in cirrhotics and its potential association with Helicobacter pylori (H. pylori) infection, the underlying etiology and severity of liver disease, and other manifestations of portal hypertension (PH). METHODS: We enrolled consecutive asymptomatic cirrhotic patients who underwent screening endoscopy in a tertiary hospital during a 12-month period. We recorded the presence of PUD and the endoscopic findings associated with PH. H. pylori infection was documented through either histology or CLO-test. The diagnosis of cirrhosis was based on elastography, liver biopsy or a combination of clinical, biochemical and imaging data. RESULTS: One hundred patients (M/F: 54/46, mean age: 61±14 years) were included in the analysis. Viral hepatitis (37%) and alcohol (22%) were the most common causes of cirrhosis. Child-Pugh stage was A/B/C: 60/35/5. PUD was found in 19 patients (14 gastric, 5 duodenal). H. pylori infection was diagnosed in 54%. Varices were detected in 59% (39% needed treatment). PH gastropathy was present in 81% (severe in 33%). The presence of PUD was unrelated to the etiology and the severity of liver disease or to other endoscopic manifestations of PH. No correlation was found between PUD and H. pylori infection. CONCLUSIONS: A high prevalence of PUD was observed in our cirrhotic patients, although they were asymptomatic and had no known risk factors of ulcerogenicity. The value of screening endoscopy for the early diagnosis and treatment of PUD in cirrhotics deserves further investigation.

Role of Spleen Stiffness Measurement by 2D-Shear Wave Elastography in Ruling Out the Presence of High-Risk Varices in Cirrhotic Patients.

BACKGROUND AND AIM: To evaluate if spleen stiffness measurement (SSM) can rule out the presence of high-risk varices in patients with cirrhosis, avoiding an upper gastrointestinal endoscopy (UGE). METHODS: We enrolled 71 cirrhotic patients irrespective of liver disease's etiology. 2D shear wave elastography (SWE) of spleen and UGE was performed. High-risk varices (HRV) were defined as esophageal varices ≥ 5 mm and/or red spots and any gastric varices. RESULTS: Esophageal varices were documented in 37 (52.1%) and HRV in 25 (35.2%) patients. SSM was not technically feasible in 7/71 patients (9.8%). From the remaining 64 patients, when those with cholestatic liver disease were excluded (n = 17), SSM < 35.8 kPa was found to exclude well the existence of HRV offering an AUROC of 0.854 (p < 0.001), sensitivity 88.9%, negative predictive value (NPV) 91.3%, specificity 72.4%, and positive predictive value (PPV) 66.7%. Only 2/47 patients (4.3%) were misclassified, and 23 (48.9%) could avoid endoscopy. In the total cohort of 64 patients, SSM < 33.7 kPa was found to exclude well the presence of HRV offering AUROC 0.792 (p < 0.001), sensitivity 91.7%, specificity 60%, NPV 92.3%, and PPV 57.9%. The misclassification rate was 3.1% (2/64), while 26/64 (40.6%) could avoid endoscopy. CONCLUSIONS: 2D-SWE of spleen is a reliable method for ruling out the presence of HRV in cirrhotic patients. If larger studies confirm our results, a large number of endoscopies could be avoided.

Evaluation of Plasma Trace Elements in Different Stages of Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is considered as the hepatic manifestation of metabolic syndrome. Its global prevalence is estimated between 25 and 45%, occurring mainly in overweight individuals with unhealthy dietary habits and low levels of physical activity. Many studies have investigated the association of trace elements with liver diseases, though not with NAFLD. In this work, we investigated trace element levels in plasma of patients and not-patients and their possible association with various stages of the disease. Inductively coupled plasma mass spectrometry (ICP-MS) was employed for the determination of As, Ba, Cd, Co, Cs, Cu, Fe, Rb, Sr, Tl, and Zn in the plasma of 189 free-living residents of Athens, Greece, either healthy or patients with mild, moderate, or severe NAFLD. The disease was diagnosed by abdominal ultrasound; blood samples were analyzed for total, HDL and LDL cholesterol, triglycerides, fasting glucose, fasting insulin, and liver enzymes, namely aspartate aminotransferase (AST), alanine transaminase (ALT), and γ-glutamyltransferase (Gamma-GT); insulin resistance was determined by the homeostatic model assessment (HOMA-IR). Zinc exhibited a statistically significant negative association with the severity of the disease, while cesium showed a statistically significant positive association. Moreover, thallium and iron were inversely associated with insulin levels. Trace element determination in plasma could be useful for establishing relationships with NAFLD status of patients. Further research is required for the verification and interpretation of these findings.

Clinical and epidemiological characteristics of hepatitis C virus-infected people who inject drugs: a Greek descriptive analysis.

BACKGROUND: It is estimated that 17,000 people who inject drugs (PWID) in Greece have hepatitis C virus (HCV) viremia. The aim of our study was to explore the characteristics of the HCV-infected, direct acting antiviral (DAA)-naïve PWID. METHODS: This is a retrospective analysis of PWID with HCV infection. We selected data from six liver clinics during the period from 1st May 2014 to 31st May 2017 in order to record the characteristics of infected PWID. RESULTS: We included 800 PWID with HCV infection (78.5% male, mean age 42±10 years) who had not received DAAs before 1st June 2017. One third of the patients had comorbidities (diabetes mellitus, arterial hypertension and psychological disorders); 70% were smokers, 27% alcohol users, 67% unemployed, 29% married, and 34% had education >12 years; 65% were attending addiction programs; 57% were receiving methadone and 36% buprenorphine. Sporadic or systemic drug use was reported by 37% while 1.4% and 2.9% had HIV and HBV coinfection, respectively. The genotype distribution was 20.5%, 4.6%, 3.3%, 61% and 10% for genotypes 1a, 1b, 2, 3 and 4, respectively. Mean (±SD) liver stiffness was 9±7 kPa and 21% of the patients had cirrhosis. Half of the patients were in the F0-F1 stage of liver disease, defined as stiffness ≤7 kPa. CONCLUSIONS: Our real-life data suggest that HCV genotype 3 remains the predominant genotype among PWID. One third of PWID had comorbidities and one-fifth cirrhosis. Half of PWID had early-stage liver disease and remained without access to DAAs according to the Greek prioritization criteria.

DARING-B: discontinuation of effective entecavir or tenofovir disoproxil fumarate long-term therapy before HBsAg loss in non-cirrhotic HBeAg-negative chronic hepatitis B.

BACKGROUND: The remission rates after stopping antivirals in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) vary among studies, while reliable predictors of relapse have not been identified. This prospective study assessed rates and predictors of relapse and retreatment in 57 non-cirrhotic hepatitis B surface antigen (HBsAg)-positive patients with HBeAg-negative CHB who discontinued effective ≥4-year entecavir or tenofovir disoproxil fumarate (TDF) therapy. METHODS: A total of 57 patients discontinued therapy after median virological remission of 5.3 years and remained under close follow-up. They were retreated with entecavir/TDF if they fulfilled predetermined criteria. RESULTS: During median follow-up of 18 months, no patient died, developed jaundice or liver decompensation. The cumulative relapse rates varied according to HBV DNA and alanine aminotransferase cutoffs; for HBV DNA >2,000 IU/ml, they were 56%, 70% and 72% at 3, 12 and 18 months after stopping entecavir/TDF. The cumulative probability of retreatment was 18% and 26% at 3 and 12 months being significantly affected only by pretreatment fibrosis severity (adjusted relative hazard: 3.43; P=0.015). Cumulative rates of HBsAg loss were 5%, 16% and 25% at 6, 12 and 18 months being higher in patients with lower HBsAg levels at treatment discontinuation. CONCLUSIONS: Our prospective study shows that effective ≥4-year entecavir/TDF therapy can be safely discontinued in non-cirrhotic HBeAg-negative CHB patients. The probability of relapse decreased after month 6. Despite common virological relapses, most patients, particularly those with mild-moderate pretreatment fibrosis, remain without retreatment, at least in the first 18 months, as a substantial proportion of them clear HBsAg and the majority eventually enters into an inactive carrier state.

Fecal calprotectin measurement is a marker of short-term clinical outcome and presence of mucosal healing in patients with inflammatory bowel disease.

AIM: To evaluate the utility of fecal calprotectin (FC) in predicting relapse and endoscopic activity during follow-up in an inflammatory bowel disease (IBD) cohort. METHODS: All FC measurements that were obtained during a 3-year period from patients with inflammatory bowel disease in clinical remission were identified. Data regarding the short-term (6 mo) course of the disease were extracted from the medical files. Exclusion criteria were defined as: (1) An established flare of the disease at the time of FC measurement, (2) Loss to follow up within 6 mo from baseline FC measurement, and, (3) Insufficient data on file. Statistical analysis was performed to evaluate whether baseline FC measurement could predict the short term clinical relapse and/or the presence of mucosal healing. RESULTS: We included 149 [Crohn's disease (CD) = 113, Ulcerative colitis (UC) = 36, male = 77] IBD patients in our study. Within the determined 6-month period post-FC measurement, 47 (31.5%) had a disease flare. Among 76 patients who underwent endoscopy, 39 (51.3%) had mucosal healing. Baseline FC concentrations were significantly higher in those who had clinical relapse compared to those who remained in remission during follow up (481.0 µg/g, 286.0-600.0 vs 89.0, 36.0-180.8, P < 0.001). The significant predictive value of baseline median with IQR FC for clinical relapse was confirmed by multivariate Cox analysis [HR for 100µg/g: 1.75 (95%CI: 1.28-2.39), P = 0.001]. Furthermore, lower FC baseline values significantly correlated to the presence of mucosal healing in endoscopy (69.0 µg/g, 30.0-128.0 vs 481.0, 278.0-600.0, in those with mucosal inflammation, median with IQR, P < 0.001). We were able to extract cut-off values for FC concentration with a high sensitivity and specificity for predicting clinical relapse (261 µg/g with AUC = 0.901, sensitivity 87.2%, specificity 85.3%, P < 0.001) or mucosal healing (174 µg/g with AUC = 0.956, sensitivity 91.9%, specificity 87.2%, P < 0.001). FC was better than CRP in predicting either outcome; nevertheless, having a pathological CRP (> 5 mg/L) in addition to the cut-offs for FC, significantly enhanced the specificity for predicting clinical relapse (95.1% from 85.3%) or endoscopic activity (100% from 87.2%). CONCLUSION: Serial FC measurements may be useful in monitoring IBD patients in remission, as FC appears to be a reliable predictor of short-term relapse and endoscopic activity.

Adherence to follow-up and treatment recommendations in Greek and immigrant patients with chronic hepatitis B in Greece.

BACKGROUND/AIM: Immigrants have multiple barriers to access to health care systems. We evaluated the adherence to follow-up and treatment recommendations of chronic hepatitis B virus (HBV) Greek and immigrant patients. METHODS: In total, 1001 consecutive adult patients with chronic HBV infection who visited our clinics for the first time between 2002 and 2011 were included. All patients born outside Greece were considered immigrants. Diagnosis was considered to be complete if patients could be classified into HBeAg-positive chronic hepatitis B (CHB), inactive carriers, HBeAg-negative CHB, or decompensated cirrhosis. RESULTS: Of the patients, 56% were Greeks and 44% were immigrants. Greeks visited our clinics at a significantly older mean age (50 vs. 35 years, P<0.001) and more frequently with advanced liver disease (11.4 vs. 6.4%, P=0.007). During the first year, Greeks more frequently had several tests and eventually a complete diagnosis (68 vs. 55%, P<0.001). Greeks were more frequently in the phase of HBeAg-negative CHB and less frequently in the phase of inactive carrier or HBeAg-positive CHB, but age was the main determinant for these differences in multivariate analysis. Treatment was initiated more frequently by Greeks than immigrants with treatment indications (86 vs. 65%, P<0.001). Only 30-33% of treated and 4-10% of untreated patients remained under follow-up at year 5, without significant differences between Greeks and immigrants. CONCLUSION: Adherence to follow-up recommendations is rather poor for all chronic HBV patients. Immigrants are lost more frequently during the first year, but only small proportions of treated and particularly untreated Greek or immigrant patients remain under long-term follow-up.

Elevated Serum Levels of the Antiapoptotic Protein Decoy-Receptor 3 Are Associated with Advanced Liver Disease.

Background. Decoy-receptor 3 (DcR3) exerts antiapoptotic and immunomodulatory function and is overexpressed in neoplastic and inflammatory conditions. Serum DcR3 (sDcR3) levels during the chronic hepatitis/cirrhosis/hepatocellular carcinoma (HCC) sequence have not been explored. Objective. To assess the levels and significance of sDcR3 protein in various stages of chronic liver disease. Methods. We compared sDcR3 levels between healthy controls and patients with chronic viral hepatitis (CVH), decompensated cirrhosis (DC), and HCC. Correlations between sDcR3 levels and various patient- and disease-related factors were analyzed. Results. sDcR3 levels were significantly higher in patients with CVH than in controls (P < 0.01). sDcR3 levels were elevated in DC and HCC, being significantly higher compared not only to controls (P < 0.001 for both) but to CVH patients as well (P < 0.001 for both). In addition, DcR3 protein was detected in large quantities in the ascitic fluid of cirrhotics. In patients with CVH, sDcR3 significantly correlated to fibrosis severity, as estimated by Ishak score (P = 0.019) or by liver stiffness measured with elastography (Spearman r = 0.698, P < 0.001). In cirrhotic patients, significant positive correlations were observed between sDcR3 levels and markers of severity of hepatic impairment, including MELD score (r = 0.653, P < 0.001). Conclusions. Circulating levels of DcR3 are elevated during chronic liver disease and correlate with severity of liver damage. sDcR3 may serve as marker for liver fibrosis severity and progression to end-stage liver disease.

Boceprevir for chronic HCV genotype 1 infection in treatment-experienced patients with severe fibrosis or cirrhosis: The Greek real-life experience.

BACKGROUND: The aim of our study was to evaluate the safety and efficacy of triple therapy using boceprevir (BOC) with pegylated interferon (pIFN)/ribavirin (RBV) in chronic hepatitis C (CHC) genotype 1 (G1) treatment-experienced patients with advanced fibrosis or compensated cirrhosis. METHODS: We report the Greek experience on the first CHC patients who received BOC-based regimen. From September 2011 to June 2012, 26 treatment-experienced CHC patients and G1 with bridging fibrosis or compensated cirrhosis received 48 weeks of BOC+pIFN+RBV antiviral therapy. Data on complete blood counts and HCV RNA levels were obtained prior to therapy, at treatment weeks 4, 8, 12, 24, 36, 48 and 24 weeks after the end of treatment. RESULTS: A full set analysis was performed in 25 of 26 patients. Nine patients (36%) achieved sustained viral response (SVR). Ten patients (40%) stopped the therapy because of futility rules and 3 (12%) due to adverse events. Four patients (16%) developed a virological breakthrough (3 of those presented futility rules as well) and 2 (8%) relapse. All patients who achieved SVR had G 1b, 6 (67%) were non-cirrhotic and 5 (55%) had >1 log decline in baseline HCV RNA levels at week 4 of the treatment. There were no deaths, while two patients were hospitalized due to side effects. CONCLUSION: The triple therapy with BOC+pIFN+RBV in this cohort of real-life treatment-experienced CHC G1 patients and advanced liver disease was safe offering cure in the majority of those who could tolerate and complete treatment under a close monitoring.

The impact of newer nucleos(t)ide analogues on patients with hepatitis B decompensated cirrhosis.

BACKGROUND/AIM: Patients with HBV-related decompensated cirrhosis (HBV-DeCi) should be treated with potent nucleos(t)ide analogues (NA)[entecavir (ETV) or tenofovir (TDF)]. The aim was the evaluation of safety and efficacy in terms of changes in liver disease course in HBV-DeCi patients treated with ETV or TDF. METHODS: In 52 HBV-DeCi patients clinical and laboratory data, including glomerular filtration rates (GFR), were recorded. The changes in MELD (DMELD) and Child-Pugh (DCTP) scores between baseline and after 6 months of treatment were evaluated. The independent factors associated with survival were evaluated. RESULTS: 31 patients under TDF and 21 under ETV were evaluated. During a median follow-up of 22.5 months (range: 6-68), there were no differences between the two groups in GFR and serum phosphate levels. At the end of follow up, in the TDF group, 2 patients died and 3 received liver transplantations (LT), while in the ETV group, 1 patient died and 3 received LT. In multivariable Cox regression analysis, DMELD was independently associated with the outcome in the total cohort (HR: 1.78, 95%C.I.:1.12-2.79, P=0.013) as well as in the subgroup of naïve (n=37) patients (HR: 1.8, 95%C.I.:1.19-4.5, P=0.03). Finally, in the non-hepatocellular carcinoma patients, the DCTP score was independently associated with the outcome in the total cohort (HR: 2.64, 95%C.I.: 1.21-7.29, P=0.015). CONCLUSIONS: TDF and ETV appear to have similar renal safety profile in HBV-DeCi patients. DMELD score in the total cohort and DCTP score in non-HCC patients were independently associated with the outcome; these findings need confirmation in larger studies.

Effect of infliximab on the healing of intestinal anastomosis. An experimental study in rats.

BACKGROUND AND AIM: Infliximab is effective in the induction and maintenance of remission in Crohn's disease. Whether, the perioperative administration of anti-TNF-a compromises intestinal healing leading to anastomotic failure and increased risk of postoperative complications, remains controversial. The aim of the study was to evaluate the effect of Infliximab on intestinal anastomosis healing. METHODS: Fifty six wistar rats were divided into 4 groups: (a) 20 rats were subjected to excision of part of the terminal ileum followed by anastomosis which was evaluated on the 3rd or 7th postoperative day; (b) 20 rats received Infliximab and thereafter, the same surgical protocol as group (a) was followed; (c) 8 rats received Infliximab and served as relative control group; and (d) 8 served as absolute control group. Bursting pressure was used for testing intestinal healing. Additionally, the anastomoses were examined macroscopically, histologically and immunohistochemically for TGFb1, MMP1, MMP2 and Collagen V. The results were confirmed by Western blot analysis. RESULTS: There were no significant differences in bursting pressures and septic intra-abdominal events among non-Infliximab (a) and Infliximab-treated (b) groups. Infliximab-treated (b) group showed mild to moderate inflammation, whereas the non-Infliximab (a) group exhibited severe inflammation. Expression of TGFb1, MMP2 and collagen V was significantly higher in the Infliximab-treated (b) group. CONCLUSION: Infliximab seems to influence intestinal healing in terms of less inflammatory activity and higher tissue remodeling activity.
