Abstract
INTRODUCTION Harmful alcohol consumption is one of the leading risk factors for global disease burden and injury condition, causing death and disability early in life, with over 3 million deaths worldwide every year. Alcoholic hepatitis (AH) is a clinical syndrome characterized by hepatic failure with recent onset of jaundice, consequence of a heavy chronic alcohol drinking. The disease severity ranges from mild to severe cases, with high short-term mortality. Individual variety regarding disease outcome and therapeutic response complicates the prognosis stratification. Thus, novel parameters and continuously sought for a better disease outcome assessment. AIMS AND OBJECTIVES To highlight new parameters that accurately assess 30-day mortality (short-term) in patients with AH and to develop a new severity score that uses readily available parameters accessible to any clinician. MATERIALS AND METHODS This is a prospective study on patients diagnosed with AH between 2022-2023. We identified 70 patients with AH who met the National Institute on Alcohol Abuse and Alcoholism (NIAAA) criteria for diagnosis after exclusion of patients with severe comorbidities that could influence disease outcome. Clinical and paraclinical parameters were assessed at least on admission and day 7. Mortality at 30-day was considered the endpoint. The database was composed using Microsoft Excel (Microsoft Corporation) and the data was analyzed using SPSS Statistics version 26 (IBM Corporation). RESULTS A total of 70 patients were included in the study with a mortality at 30-days of 22.9% (n=16). The independent variables associated with increased short-term mortality identified using the univariate analysis were: fever, infection, esophageal varices, prothrombin time PT, INR, total bilirubin, CRP, LDH and CHI (creatinine height index). Using multivariate regression we determined a novel prognostic score, with criterion for retaining variable being p<0.05. Total bilirubin day 7, CRP, PT, fever and CHI resulted after the analysis and were included into a new mortality score. Our Prognostic Model Score obtained an area under the ROC of 0.950 (95% CI: 0.890-0.980, p<0.001), with a cut-off value of 13.75 (Sn=87.5%, Sp=91%). Regarding the consecrated prognostic scores, MDF and Lille score obtained good AUROCs=0.839 and 0.881, respectively (p<0.000), with cut-off values comparable with literature (MDF=34.35 vs 32) and (Lille=0.475 vs 0.450). The discriminatory power for ABIC (p=0.58), GAHS (p=0.16), MELD-Na (p=0.61) was not significant. CONCLUSION We obtained a new prognostic score for the assessment of 30-day mortality in AH that includes markers of inflammation (CRP, fever) and markers of sarcopenia (CHI) along parameters of hepatic disfunction (total bilirubin and PT). Amongst consecrated prognostic models, MDF and Lille scores were representative for our study, while ABIC, GAHS and MELD-Na did not attain statistical significance. Our score is unique by the addition of CRP and this could prove to be a useful tool in AH severity stratification.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal disorders in the world. Two parameters, mean nocturnal baseline impedance (MNBI) and post-reflux swallow-induced peristaltic wave index (PSPW), have been recently proposed to help differentiate GERD phenotypes. Our study aimed to assess whether there is any correlation between the two parameters, while also taking a look at their ability to distinguish between GERD phenotypes. We recruited 81 patients who were divided into 4 groups based on their GERD phenotype: erosive reflux disease (ERD), non-erosive reflux disease (NERD), reflux hypersensitivity (RH), and functional heartburn (FH). Both MNBI (AUROC 0.855) and PSPW (AUROC 0.835) had very good performances in separating ERD patients from non-ERD patients. PSPW (AUROC 0.784) was superior to MNBI (AUROC 0.703) in distinguishing NERD patients from patients with RH or FH. The PSPW index (AUROC 0.762) was more effective than MNBI (AUROC 0.668) in separating RH from FH. We found that PSPW and MNBI have a strong statistical correlation (Pearson correlation coefficient, r = 0.722, p < 0.001). Furthermore, PSPW predicted pathological MNBI (<2292 Ω) with good performance (AUROC 0.807). MNBI and PSPW are useful in distinguishing GERD phenotypes, with a strong correlation between the two parameters.

Abstract
BACKGROUND AND AIMS Gastroesophageal reflux disease (GERD) is one of the most frequent digestive pathologies. The current diagnosis of GERD either by trial of proton pump inhibitors (PPIs), endoscopy or by multichannel impedance pH study (MII/pH) has limitations. Our study aims to show if mean nocturnal baseline impedance (MNBI) can differentiate between the GERD phenotypes. METHODS We recruited 62 patients who underwent upper digestive endoscopy and MII/pH, with some patients undergoing esophageal manometry to exclude motility disorders. Patients were separated into 4 GERD phenotypes: erosive reflux disease (ERD), non-erosive reflux disease (NERD), reflux hypersensitivity (RH) and functional heartburn (FH). Proximal MNBI was calculated as the mean value of the proximal 2 channels (Z1 and Z2), and distal MNBI was calculated as the mean value of the distal 4 channels (Z3, Z4, Z5, Z6). RESULTS Distal MNBI can help distinguish the abnormal acid exposure time (AET) phenotypes (ERD, NERD) from normal AET phenotypes (RH, FH) with a decent performance (AUROC 0.857). Distal MNBI has good accuracy in separating ERD from other phenotypes (AUROC 0.872). Furthermore, distal MNBI can differentiate FH from ERD, NERD, RH with good accuracy (AUROC 0.879), and on top of that is able to separate FH from RH (AUROC 0.817). CONCLUSIONS Our study showed that distal MNBI is a good method of differentiating GERD phenotypes and should be taken into consideration in future studies to assess its validity in helping physicians make the correct diagnosis.

Abstract
Background: While non-alcoholic fatty liver disease (NAFLD) is a wide-spread liver disease, only some patients progress towards steatohepatitis and cirrhosis. Aim: We comparatively analyzed the methacetin breath test (MBT) for the microsomal function of the liver and the octanoate breath test (OBT) for mitochondrial activity, in detecting patients with steatohepatitis and estimating fibrosis. Methods: 81 patients with histologically proven NAFLD (SAF score) were evaluated. The parameters used for both breath tests were the dose/h and the cumulative dose recovery at multiple timepoints. The statistical association between histological diagnosis and breath test results used Independent Samples t Test. The accuracy for diagnosis was evaluated using area under the receiver operator characteristic (AUROC) and the sensitivity and specificity were assessed using the Youden J method. Results: Both MBT and OBT were able to differentiate patients with simple steatosis from NASH and to stratify patients with significant fibrosis and cirrhosis (p-values < 0.001 for most analyzed timepoints). The best parameter for NASH diagnosis was OBT dose at 30 min. In the case of significant fibrosis, the most accurate test was MBT cumulative dose at 30 min. Conclusions: Both MBR and OBT tests are potentially useful tools in assessing patients with NAFLD.

Abstract
BACKGROUND The diagnosis of NASH needs a liver biopsy, an invasive procedure that is not frequently accepted by patients. The aim of our study was to evaluate the efficacy of the 13C-Octanoate breath test (OBT) as a non-invasive surrogate marker to differentiate patients with NASH from patients with simple steatosis (NAFL). METHODS We performed a prospective study on patients with histologically established non-alcoholic steatohepatitis and no other hepatic disease. Each patient underwent a testing protocol, which included a clinical exam, laboratory blood tests, standard abdominal ultrasound, and a 13C-Octanoate breath test. RESULTS The study group included: 82 patients with steatohepatitis, 64 patients with simple steatosis, and 21 healthy volunteers. The univariate and bivariate analysis identified that significant values were the percent dose recovery (PDR) at 15 min-r = 0.65 (AUROC = 0.902) and cumulative percent dose recovery (cPDR) at 120 min-r = 0.69 (AUROC = 0.899). DISCUSSION Our study showed that 13C-OBT had good efficacy for identifying patients with NASH from those with NAFL (steatosis alone) but not those with NAFL from healthy subjects. Considering all these pathogenic steps in NASH we considered that OBT could have the clinical utility to identify patients at risk for NASH, especially "fast progressors".

Abstract
The current data on climate change and environmental degradation are dramatic. The consequences of these changes are already having a significant impact on people's health. Physicians - as advocates of the patients, but also as citizens - have an ethical obligation to be involved in efforts to stop these changes. The European Federation of Internal Medicine (EFIM) strongly encourages the Internal Medicine societies and internists across Europe to play an active role in matters related to climate change and environmental degradation. At a national level, this includes advocating the adoption of measures that reduce greenhouse gas (GHG) emissions and environmental degradation and contributing to policy decisions related to these issues. At a hospital level and in clinical practice, supporting actions by the health sector to reduce its ecological footprint is vital. At the level of EFIM and its associated internal societies, promoting educational activities and developing a toolkit to prepare internists to better care for citizens who suffer from the consequences of climate change. In addition to advocating and implementing effective actions to reduce the ecological footprint of the health industry, recommending the introduction of these themes in scientific programs of Internal Medicine meetings and congresses and the pre- and postgraduate medical training. At a personal level, internists must be active agents in advocating sustainable practices for the environment, increasing the awareness of the community about the health risks of climate change and environmental degradation, and being role models in the adoption of environmentally friendly behaviour.

Abstract
Background and Objectives: Non-alcoholic fatty liver disease (NAFLD)-related severe liver fibrosis is associated with a higher risk of progressing to decompensated cirrhosis and hepatic failure and developing NAFLD-related hepatocellular carcinoma (HCC), particularly in populations with diabetes. Our pilot study aims to evaluate the performances of various noninvasive methods in predicting liver fibrosis in a population of patients with diabetes and to establish a new scoring system for the prediction of severe fibrosis (>F3). Materials and Methods: A total of 175 patients with diabetes were enrolled for liver fibrosis evaluation. Using the degree of agreement (concordance) between a noninvasive score based on serum biomarkers (NAFLD fibrosis score) and point shear-wave elastography (pSWE) as the reference method, we generated receiver operating characteristic (ROC) curves and performed a multivariate analysis to predict severe liver fibrosis. Results: In our population of patients with diabetes, gamma-glutamyltransferase (GGT), age, body mass index (BMI), the homeostatic model assessment of insulin resistance (HOMA-IR), and glycosylated hemoglobin (HbA1C) were significant predictors for the diagnosis of the F3/F4 group (area under the ROC: 0.767, 0.743, 0.757, 0.772, and 0.7, respectively; p < 0.005 for all). Moreover, the combined composite score (the sum of GGT, age, BMI, HOMA index, and HbA1C) had the highest diagnostic performance at a cut-off value of 3 (AUROC—0.899; p < 0001). The sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) were 91.20%, 79%, 79%, and 89%, respectively, and 89% of patients were correctly classified as having severe liver fibrosis. In contrast with the Fibrosis 4 (FIB-4) score and the AST-to-platelet ratio index (APRI), the composite score had the best accuracy in discriminating advanced fibrosis. Conclusions: The proposed composite score had a reliable and acceptable diagnostic accuracy in identifying patients with diabetes at risk of having severe fibrosis using readily available laboratory and clinical data.

Abstract
Artificial intelligence (AI) is not a new idea or field of research. However, recent advancements in computing technology as well as increasing worldwide experience in applying AI to various fields have enabled us to hope that applying it to the medical practice could improve outcomes. The aim of the article was to evaluate potential applications of artificial intelligence (AI) in the clinical practice of gastroenterology. AI algorithms can offer many benefits over the traditional diagnostic, prognostic, therapeutic scores, or non-AI enhanced procedures that we perform today. It can very easily process complex mathematical data, which would allow to account for many parameters and with highly sophisticated formulas to determine a conclusion, to a degree that would be impractical or impossible for a human to do alone in the clinical practice. This could allow for significantly more individualized treatments for each patient. As more data becomes available, it can be fed into the algorithm, which allows it to change based on the new data. However, we must be aware that most studies performed today are still early retrospective studies, and their utility still needs to be evaluated in future large scale prospective studies. Apart from the medical challenges, it must be noted that the impact of large-scale implementation of artificial intelligence will have challenges related to ethical and financial aspects as well.

Abstract
This prospective study aimed to determine the manometric pattern and the prevalence of esophageal dysmotility in 79 morbidly obese patients selected for laparoscopic sleeve gastrectomy. After clinical evaluation and upper gastrointestinal endoscopy, high-resolution esophageal manometry was performed. The esophageal peristalsis, lower esophageal sphincter (LES) basal pressure, and LES relaxation were evaluated. Demographic data showed a predominance of females (55.70%) and both females and males were in the 5th decade of life. In addition, approximately 3/4 of the patients (78.48%) were from the urban zone. The mean body mass index of the patients was 46.40±6.0069 kg/m2, with a maximum of 61 kg/m2. The LES basal pressure was normal in 59.49% of the patients, with a mean value of 31.40±18.43 mmHg. LES basal hypertonia was observed in 26.58%, and LES hypotonia in 13.93% of patients; 46.84% (37 patients) had abnormal manometric findings: 24.05% (19 patients) had EGJ outflow obstruction, 12.66% (10 patients) ineffective esophageal motility, 3.8% (3 patients) distal esophageal spasm, 3.8% (3 patients) Jackhammer esophagus, 2 cases were suggestive for type 2 achalasia but in asymptomatic patients. Ineffective esophageal motility was not associated with diabetes mellitus type 2 or erosive esophagitis according to our data. Hiatal hernia (HH) was manometrically diagnosed in 23 patients (29.11%). Preoperative high-resolution esophageal manometry in obese patients demonstrated a high prevalence of motility disorders, but in asymptomatic patients, thus in the future, we require more studies and larger cohorts to better appreciate the clinical impact.

Abstract
The purpose of this study is to determine whether esophageal varices (EV) can be identified through the evaluation of spleen stiffness (SSM) via acoustic radiation force impulse (ARFI). A total of 135 patients suffering from cirrhosis underwent a clinical exam, laboratory tests, abdominal ultrasound, liver stiffness (LSM) measurement, SSM evaluation and upper gastrointestinal endoscopy. Based on the endoscopy results, the patients were classified into three groups: those with no evident EV, those with small EV and those with varices needing treatment (VNT). Patients with EV of any grade had significantly higher average SSM values over those with no EV (3.37 m/s versus 2.79 m/s, p-value < 0.001), while patients with VNT showed an even greater difference (3.96 m/s versus 2.93 m/s, p-value < 0.001). SSM proved to be an excellent method of predicting patients with VNT.

Abstract
Inflammatory bowel diseases have an important impact upon the economic and social status due to their increasing incidence and prevalence, often affecting young people. At the moment, the therapeutic goal goes beyond the improvement of symptoms and laboratory parameters, being represented by endoscopic mucosal healing, changing the disease's natural history. Even though endoscopy is the gold standard for the assessment of mucosal healing, it is an invasive maneuver and it lacks good repeatability. These patients require frequent evaluation; therefore, interest for noninvasive techniques has risen.As a consequence, the importance of intestinal ultrasound has increased lately and recent studies support its use to assess the degree of inflammation, to differentiate between remission and relapse, to monitor therapy response and guide treatment, to evaluate prognosis, and to diagnose complications. Another promising noninvasive imagistic technique is elastography which has gained interest because of its capacity to discriminate between inflammatory and fibrotic tissue, taking into account the different therapeutic options for the fibrotic strictures compared to inflammatory processes. This review summarizes the actual recommendations regarding the use of intestinal ultrasound and elastographic techniques for the diagnosis and monitoring of inflammatory bowel diseases.

Abstract
BACKGROUND & OBJECTIVES The development and evaluation of non invasive tests to assess liver fibrosis have been an active field of research. The present study was carried out to evaluate the role of 13C-methacetin breath test 13C-MBT) as a non invasive tool for liver fibrosis staging in patients with chronic hepatitis C (CHC). METHODS 13C-Methacetin breath test was performed in 115 patients with CHC histologically proven and in 55 healthy controls. All patients and controls underwent routine liver function tests. The CHC patients underwent histological assesment of liver by percutaneous liver biopsy. The correlation between the 13C-methacetin breath test and liver biopsy was tested using Kendall's rank correlation coefficients. The overall validity was expressed as area under receiver operating characteristic curve (AUROC) with 95%CI. RESULTS Delta over baseline values (DOB) of CHC patients at 20 min were significantly reduced compared with control (16. 2 vs. 21. 06%, p <0.001). There were also significant differences between CHC patients and controls as regard the metabolization speed (dose/h at 20 min (17.80 vs 28.6, p <0.001) and metabolization capacity (cumulative recovery after 60 min (13.8 vs 20.4 p <0.001). The best 13C-MBT parameter correlated with fibrosis was DOB at 20 min (r = -0.596). The optimal cut-off for the diagnosis of advanced fibrosis (F ≥ 3) was 15.2 per cent, with AUROC = 0.902, 95%CI: (0.851-0.938), a sensitivity of 82 per cent and a specificity of 80 per cent. DOB at 20 min predicted even better cirrhosis: AUROC = 0.932 95 per cent CI = 0.901-0.953, a sensitivity of 96 per cent and a specificity of 92 per cent. INTERPRETATION & CONCLUSIONS Based on our findings the 13C-methacetin breath test appears to be a promising tool to identify CHC patients with advanced fibrosis and to replace liver biopsy. Further studies need to be done to assess its potential to be used in regular clinical practice.

Abstract
The use of liver elastography has substantially developed in the past few years; the introduction of novel elastographic methods (Transient Elastography, point Shear Wave Elastography, Real Time Shear Wave Elastography, Strain Elastography) has changed the perspective in the evaluation of liver disease. The ongoing research in this area is mainly focused on diffuse liver diseases and for predicting liver cirrhosis complication. This guideline created under the auspice of Romanian Society of Ultrasound in Medicine and Biology is intended to accustomize the clinician with the current practical use of liver elastography and has been issued to help in maximizing the clinical benefit for the patients with chronic liver diseases.

Abstract
BACKGROUND Acoustic Radiation Force Impulse Elastography is a new method for non-invasive evaluation of liver fibrosis. AIM To evaluate the impact of elevated alanine aminotransferase levels on liver stiffness assessment by Acoustic Radiation Force Impulse Elastography. METHODS A multicentre retrospective study including 1242 patients with chronic liver disease, who underwent liver biopsy and Acoustic Radiation Force Impulse. Transient Elastography was also performed in 512 patients. RESULTS The best Acoustic Radiation Force Impulse cut-off for predicting significant fibrosis was 1.29 m/s in cases with normal alanine aminotransferase levels and 1.44 m/s in patients with alanine aminotransferase levels>5 × the upper limit of normal. The best cut-off for predicting liver cirrhosis were 1.59 and 1.75 m/s, respectively. Acoustic Radiation Force Impulse cut-off for predicting significant fibrosis and cirrhosis were relatively similar in patients with normal alanine aminotransferase and in those with alanine aminotransferase levels between 1.1 and 5 × the upper limit of normal: 1.29 m/s vs. 1.36 m/s and 1.59 m/s vs. 1.57 m/s, respectively. For predicting cirrhosis, the Transient Elastography cut-offs were significantly higher in patients with alanine aminotransferase levels between 1.1 and 5 × the upper limit of normal compared to those with normal alanine aminotransferase: 12.3 kPa vs. 9.1 kPa. CONCLUSION Liver stiffness values assessed by Acoustic Radiation Force Impulse and Transient Elastography are influenced by high aminotransferase levels. Transient Elastography was also influenced by moderately elevated aminotransferase levels.

Abstract
BACKGROUND & AIMS Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in many parts of the world. The ¹³C-methacetin breath test (MBT), a microsomal liver function test, enables quantitative evaluation of cytochrome P450-dependent liver function involved in NAFLD pathogenesis. The aim of our study was to evaluate the efficacy of MBT in differentiating patients with non-alcoholic steatohepatitis (NASH) from patients with simple steatosis (SS) and its ability to predict significant fibrosis in NAFLD patients. METHODS We performed MBT in 64 patients with histologically proven NAFLD (ranging from SS to severe steatohepatitis) and in 20 healthy controls. Brunt scoring system for histological evaluation of NAFLD served as a reference. The correlation between MBT parameters and liver biopsy was tested using Spearman's coefficient. The overall validity was measured using the area under the receiver operating characteristic curve (AUROC) with 95%CI. RESULTS ¹³C-MBT is a good tool for identifying patients with histologically proven NASH, with an AUROC of 0.824, 95% CI (0.723-0.926), a sensitivity of 95% and a specificity of 74%. The diagnosis accuracy of ¹³C-MBT for significant fibrosis (F ≥2) has a validity of 91% (95% CI, AUROC = 0.830-0.989) with higher sensitivity (90%) and specificity (81%). ¹³C-MBT values predicted better F3 or F4 fibrosis (AUROC were 0.936 and 0.973). CONCLUSION Due to the impairment of microsomal function which occurs in NAFLD, ¹³C-MBT could be a reliable diagnostic and follow-up test for NAFLD patients.

Abstract
Nonalcoholic fatty liver disease (NAFLD) consists of a broad spectrum of liver lesions ranging from fatty liver (FL), through nonalcoholic steatohepatitis (NASH), up to cirrhosis. The incidence of nonalcoholic fatty liver disease has increased in recent years due to the high rate of obesity in developed countries. Although the dogma "simple steatosis - benign prognosis, nonalcoholic steatohepatitis - severe evolution" still stands for many hepatologists, plenty of data underline the unsuspected evolution, i.e., that some patients may progress from fatty liver towards cirrhosis and hepatocellular carcinoma (HCC). NAFLD is the hepatic manifestation of the metabolic syndrome. In certain metabolic circumstances, isolated hepatic steatosis is not necessarily a benign disorder associating cardiovascular risk and evolution towards severe liver diseases including HCC. We tried to shed some light on this problem, taking into account its major health impact and the variegate and sometimes unpredictable evolution of NAFLD.

Abstract
AIM The aim of this international multicenter study was to evaluate the reliability of Acoustic Radiation Force Impulse (ARFI) elastography for predicting fibrosis severity, in patients with chronic hepatitis C. PATIENTS AND METHODS We compared ARFI to liver biopsy (LB) in 914 patients (10 centers, 5 countries) with chronic hepatitis C. In each patient LB (evaluated according to the METAVIR score) and ARFI measurements were performed (median of 5-10 valid measurements, expressed in meters/second - m/s). In 400 from the 914 patients, transient elastography (TE) was also performed (median of 6-10 valid measurements, expressed in kiloPascals - kPa). RESULTS Valid ARFI measurements were obtained in 911 (99.6%) of 914 cases. On LB 61 cases (6.7%) had F0, 241 (26.4%) had F1, 202 (22.1%) had F2, 187 (20.4%) had F3, and 223 (24.4%) had F4 fibrosis. A highly significant correlation (r=0.654) was found between ARFI measurements and fibrosis (p<0.0001). The predictive values of ARFI for various stages of fibrosis were: F ≥ 1 - cut-off>1.19 m/s (AUROC=0.779), F ≥ 2 - cut-off>1.33 m/s (AUROC=0.792), F ≥ 3 - cut-off>1.43 m/s (AUROC=0.829), F=4 - cut-off>1.55 m/s (AUROC=0.842). The correlation with histological fibrosis was not significantly different for TE in comparison with ARFI elastography: r=0.728 vs. 0.689, p=0.28. TE was better than ARFI for predicting the presence of liver cirrhosis (p=0.01) and fibrosis (F ≥ 1, METAVIR) (p=0.01). CONCLUSION ARFI elastography is a reliable method for predicting fibrosis severity in chronic hepatitis C patients.

Abstract
Acoustic Radiation Force Impulse (ARFI) imaging is a novel ultrasound-based elastography method that is integrated in a conventional ultrasound machine enabling the exact localization of measurement site. It might present an alternative method to transient elastography for the noninvasive assessment of liver fibrosis. At present, studies with small patient population have shown promising results. A systematic review and meta-analysis of pooled patient data were performed to evaluate the overall performance of ARFI for the staging of liver fibrosis. Literature databases were searched up to 10/2010. The authors of the original publication were contacted, and the original patient data were requested. A meta-analysis was performed using a random effect meta-analytic method for diagnostic tests. In addition, available data comparing ARFI with FibroScan with the DeLong test were evaluated. Literature search yielded nine full-paper publications evaluating ARFI while using liver biopsy as reference method. Original patient data were available from eight studies including 518 patients. The mean diagnostic accuracy of ARFI expressed as areas under ROC curves (AUROC) was 0.87 for the diagnosis of significant fibrosis (F ≥ 2), 0.91 for the diagnosis of severe fibrosis (F ≥ 3), and 0.93 for the diagnosis of cirrhosis. ARFI can be performed with good diagnostic accuracy for the noninvasive staging of liver fibrosis.

Abstract
Abnormal hemostasis tests and bleeding are often associated in liver cirrhosis. In these patients the balance between hypo- and hypercoagulation status is more fragile than in healthy people. In the hemostatic abnormalities associated with chronic liver disease are two main chategory factors: favoring hemorrage and favoring thrombosis. The main factors that favoring hemorrage are: low platelet count, impaired platelet function, decreased levels coagulation factors (II, V, VII, IX, X, XI), quantitative and qualitative abnormalities of fibrinogen, vitamin K defiency, low levels of trombin activable fibrinolisis inhibitor, activat plasminogenic tisular. The factors favoring thrombosis are elevated levels of factors VIII and von Willebrand, decreased levels of protein C, protein S, antithrombin, decreased levels of plasminogen. Traditionally it was thought that arterial and venous thrombosis is rare events in cirrhotic patients but recent studies have indicated that thrombotic complications can paradoxically occur even if clinically an increased risk of hemorrhage is considered. Treatment of venous thrombosis in patients with cirrhosis using routine anticoagulation with heparin and vitamin K antagonists has been described but with a high level of bleeding complications. So, based on the limited data available, AASLD guidelines stated no recommendations for or against the use of anticoagulation in cirrhotic patients with portal thrombosis. Although abnormal hemostasis tests and bleeding are often associated in patients with chronic liver disease it is a relatively poor correlation between hemorrhagic risk and routine diagnostic tests of hemostasis. Management of bleeding complications in liver cirrhosis varies and no general guidelines are available. The main therapeutic strategies are: red cell concentrate, plasma, platelet concentrate, recombinant factor VIIa, factor concentrates, desmopressin, antifibrynolitic agents, thrombopoietin receptor agonists, antibiotics. Clinical studies examining safety and efficacy of the various products for the different bleedeing or trombotic complications of liver cirrhosis need to be initiaded.

Abstract
AIMS The aim of our study was to assess the clinical and biological parameters associated with Nonalcoholic steatohepatitis (NASH) and to establish the predictors of significant fibrosis in Nonalcoholic fatty liver disease (NAFLD) patients. METHODS We correlated clinical and biochemical parameters with histological features (simple steatosis or steatohepatitis) in 97 patients with NAFLD admitted to the University Hospital Bucharest for persistently raised aminotransferase levels. The biochemical parameters included lipid profile, glucose, liver tests and insulin. The Homeostatic Metabolic Assesment (HOMA)-index and the oxidative stress were also evaluated. Factors associated with NASH and severe fibrosis (F≥=3) were identified using the Mann-Whitney U test and multivariate analysis. The overall validity was measured using the area under receiver operating characteristic curve (AUROC) with 95% CI. RESULTS At univariate analysis, age, BMI, splenic longitudinal diameter (SLD), HOMA, gamma glutamyl transpeptidase, C- reactive protein (CRP), albumin and INR were significantly associated with histologically proven NASH. The multivariate analysis identified four independent predictive factors for the presence of NASH: CRP (p=0.004), SLD (p=0.018), HOMA (p=0.03) and albumin level (p=0.041). The variables independently associated with severe fibrosis were albumin (p=0.008), blood glucose (p=0.017) and BMI (p=0.048). CONCLUSION A predictive model that incorporates the clinical and biological parameters may identify at-risk patients with NAFLD, avoiding liver biopsy on a routine basis.

Abstract
Non-alcoholic fatty liver disease (NAFLD) includes a spectrum of diseases that have insulin resistance in common and are associated with metabolic conditions such as obesity, type 2 diabetes mellitus, and dyslipidemia. NAFLD ranges from simple liver steatosis, which follows a benign course, to nonalcoholic steatohepatitis (NASH), a more severe entity, with necroinflammation and fibrosis, which can progress to cryptogenic cirrhosis and end-stage liver disease. Liver biopsy remains the gold standard for evaluating the degree of hepatic necroinflammation and fibrosis; however, several noninvasive investigations, such as serum biomarkers, have been developed to establish the diagnosis and also to evaluate treatment response. These markers are currently neither available in all centers nor validated in extensive studies. Examples include high-sensitivity C reactive protein and plasma pentraxin 3, which are associated with extensive liver fibrosis in NASH. Interleukin-6 correlates with inflammation, and cytokeratin-18 represents a marker of hepatocyte apoptosis (prominent in NASH and absent in simple steatosis). Tissue polypeptide specific antigen seems to have a clinical utility in the follow-up of obese patients with NASH.

Abstract
AIM: To investigate the diagnostic accuracy of acoustic radiation force impulse (ARFI) imaging as a noninvasive method for the assessment of liver fibrosis in chronic hepatitis C (CHC) patients.
METHODS: We performed a prospective blind comparison of ARFI elastography, APRI index and FibroMax in a consecutive series of patients who underwent liver biopsy for CHC in University Hospital Bucharest. Histopathological staging of liver fibrosis according to the METAVIR scoring system served as the reference. A total of 74 patients underwent ARFI elastography, APRI index, FibroMax and successful liver biopsy.
RESULTS: The noninvasive tests had a good correlation with the liver biopsy results. The most powerful test in predicting fibrosis was ARFI elastography. The diagnostic accuracy of ARFI elastography, expressed as area under receiver operating characteristic curve (AUROC) had a validity of 90.2% (95% CI AUROC = 0.831-0.972, P < 0.001) for the diagnosis of significant fibrosis (F ≥ 2). ARFI sonoelastography predicted even better F3 or F4 fibrosis (AUROC = 0.993, 95% CI = 0.979-1).
CONCLUSION: ARFI elastography had very good accuracy for the assessment of liver fibrosis and was superior to other noninvasive methods (APRI Index, FibroMax) for staging liver fibrosis.

Abstract
The prognosis and clinical management of chronic liver diseases are highly dependent on the extent of liver fibrosis. Bigger the fibrosis, worse the prognosis; and bigger the risk of progression to cirrhosis. In current practice, liver biopsy is most frequently performed to assess the grade of inflammation and stage of fibrosis thereby providing prognostic information on which to base treatment decisions upon. Liver biopsy is becoming more and more useless in the management of chronic liver disease due to large sampling error, consistent inter-observer disagreement, high emotional cost of patient, enormous health care commitment in case of rare but possible severe complications, the fact that it is a snapshot of a process that is everything but a frozen one. Therefore, every methodology that avoids performing this invasive procedure is welcome. The purpose of this article is to present the noninvasive evaluation of patients with chronic liver disease as an alternative of liver biopsy in the assessment of hepatic structure and function.

Abstract
AIM The aim of the study was to assess the effects of valsartan, a new generation angiotensin II receptor antagonist, on portal and systemic hemodynamics and on renal function in cirrhosis. METHODS Eighty patients with cirrhosis and portal hypertension were divided in two groups as follows: group I - 40 patients who received valsartan (Diovan) 80 mg /day for 7 days and group II - 40 patients who received placebo. All the patients had hemodynamic, endocrine and renal parameters measured on day 0 and 7. The following were assessed: creatinine clearance, lithium clearance, plasma renin activity, concentration of plasma aldosteron and sodium homeostasis. Hemodynamic effects were assessed sonographically by portal flow volume and velocity evaluation, and mean arterial blood pressure. RESULTS Valsartan increased the portal blood flow and the portal velocity (p < 0.01). These changes occurred without any significant changes in blood pressure and renal function or the glomerular filtration rate, compared with controls (p > 0.05). Valsartan also reduced the concentration of plasma aldosteron (p < 0.01) and increased the urinary sodium excretion (p < 0.001). CONCLUSION A one week treatment with valsartan in cirrhotic patients with portal hypertension determines an increase in natriuresis, which could be regarded as beneficial and changes in the portal hemodynamics which might be speculated to represent a reduction of portal resistance.

Abstract
UNLABELLED Portal hypertension is the result of increased hepatic resistance and portal influx. AIM To assess the effects of Carvedilol, a 3rd-generation nonselective beta blocker with alpha1-adrenergic activity on portal and systemic homodynamic in patients with cirrhosis and portal hypertension. METHODS Fifty patients with cirrhosis and portal hypertension were divided into two groups and statistically compared as follows: group I - 25 patients received Carvedilol, 12.5 mg/day and group II - 25 patients received placebo for six days. All the patients had hemodynamic, endocrine and renal measurements before and after administration of Carvedilol or placebo. They underwent creatinine clearance, lithium clearance, plasma renin activity, concentration of plasma aldosteron and urinary sodium excretion. Hemodynamic effects were assessed by portal flow volume and velocity, cardiac output and medium blood pressure. RESULTS Carvedilol significantly increased the portal blood flow and velocity (p<0.05). Carvedilol reduced the medium blood pressure (p<0.001) with statistically insignificant alterations in creatinine clearance and 24-hours urinary sodium excretion. Carvedilol also reduced the concentration of plasma aldosteron (p < 0.002). CONCLUSIONS Carvedilol can be used as an alternative drug for the prophylactic treatment of portal hypertension with careful monitoring of blood pressure regarding its hypotensive effects.
