Background and Aims: Hepatocellular carcinoma (HCC) is a significant public health issue, with an increasing incidence and prevalence and a high incidence-to-mortality ratio. The prognosis of HCC depends on two competing factors, tumor burden and underlying liver disease severity, encompassed in the Barcelona Clinic Liver Cancer (BCLC) classification. To assess HCC staging and the way staging affects eligibility for treatment at the time of the first diagnosis in Romania in the setting of opportunistic diagnosis, in the absence of a national HCC screening policy., Methods: Data regarding HCC staging, underlying liver disease, and eligibility for treatment at the time of diagnosis was analyzed using a prospectively maintained multicentric database, which included patients from the five largest tertiary care hepatology units in the country between June 2016 and February 2020., Results: A consecutive series of 477 patients was included. The distribution within BCLC classes was as follows: very early (0) 7.1%, early (A) 34.3%, intermediate (B) 19.4%, advanced (C) 14.2%, terminal (D) 24.7%. At the time of the diagnosis, 198 (41.5%) were eligible for a curative intent treatment, while 359 (75.2%) were eligible for a disease-modifying therapy. 228 patients (47.8%) had decompensated liver disease at the time of diagnosis, the most common decompensating event being ascites (78.1%)., Conclusions: A large proportion of HCC cases are diagnosed at the time of a decompensating event, severely restricting the therapeutic potential. Proactive diagnostic strategies should be implemented to improve the rate of actionable diagnosis.

Background and Aims: The sofosbuvir (SOF) / velpatasvir (VEL) / voxilaprevir (VOX) combination has been evaluated in more than 800 patients enrolled in phase II and phase III studies, where it demonstrated excellent safety and efficacy, achieving overall sustained viral response (SVR) rates of more than 95%. We aimed to assess the efficacy and safety of SOF/VEL/VOX in a real-world study, including patients previously treated for genotype 1b hepatitis C virus (HCV) infection that did not obtain a sustained viral response with previous direct-acting antivirals (DAAs) therapy., Methods: In Romania, through a nationwide government-funded program in 2019-2020, 213 patients with chronic hepatitis C non-responders to previous DAAs therapy, received treatment with SOF/VEL/ VOX 400/100/100 mg/day for 12 weeks. We performed a retrospective longitudinal study that included 143 individuals who were treated in Bucharest, Iași, Craiova and Constanța clinics, all with genotype 1b HCV infection. Efficacy was assessed by the percentage of patients achieving SVR 12 weeks post-treatment (SVR12). Serious adverse events (SAE) were registered., Results: Our cohort comprised 53% males with a median age of 60 years (27÷77); 47% were pre-treated with ombitasvir/paritaprevir/ritonavir+dasabuvir ± ribavirin, 40% with ledipasvir/SOF, 13% with elbasvir/ grazoprevir. 42% of patients associated co-morbidities, 45% had compensated liver cirrhosis, 2% had treated hepatocellular carcinoma (HCC) and 1% had hepatitis B virus co-infection. SVR by intention to treat was reported in 139/143 (97.2%) and per protocol in 141/143 (98.6%). No predictive factors for SVR were identified. Rate of liver decompensation in patients with cirrhosis was 6% and was statistically associated in multivariate analysis with Child-Pugh score (p<0.01) and with severe steatosis (p=0.004). Occurrence of new HCC was reported in 3.6% of all patients with cirrhosis and was associated with poor liver function [higher Child-Pugh score (p=0.001) and low albumin levels (p=0.02)]. Serious adverse events related to therapy were reported in 1/143(0.7%)., Conclusions: SOF/VEL/VOX was highly efficient in our population of patients with a 97.2% SVR. Liver decompensation occurred in 6% of cirrhotic patients at SVR, related to hepatic dysfunction.

Background and Aims: The evidence regarding the use of anticoagulant (AC) agents in portal vein thrombosis (PVT) is increasing and, most patients undergo chronic treatment with low molecular weight heparin (LMWH) or vitamin K antagonists (VKA). Nevertheless, there are no clear data about who should receive antithrombotic therapy, when to initiate it, how long and what dose should be used for this set of patients. The aim of the study was to assess the outcome of patients with cirrhosis and portal vein thrombosis who received AC therapy, in terms of thrombus regression, bleeding events and survival rates., Methods: This observational and retrospective study included 107 cirrhotic patients diagnosed with PVT in a single tertiary center between 2010-2019. 54 received low molecular weight heparin or vitamin K antagonist (AC treatment group) and 53 were untreated. All patients were periodically follow-up to assess the evolution of PVT (regression, progression, stable thrombus) and potential occurrence of bleeding events., Results: The regression of portal vein thrombosis was significantly higher in the AC treatment group (OR=2.430; 95% CI=1.11-6.167; p=0.026), more than 50% of on-treatment patients experiencing regression of the thrombus. However, bleeding events were significantly more frequent in the AC treatment group (18.5% vs. 7.5%) and the risk of bleeding was associated with thrombocytes less than 50x103/mm3 (OR=8.266; 95%CI: 2.310-39.211; p=0.002). Survival was better in the AC treatment group (68.4% vs 48.7% at 5 years and 92.7% vs 77.8% at 1 year, p=0.038) and was lower in patients that experienced bleeding events (37.22% survival at 5 years, mean time survival 44 months, p=0.008)., Conclusions: In our cohort of cirrhotic patients with PVT more than 50% of patients receiving AC therapy presented regression of the thrombus; most of them obtained partial recanalization. The bleeding complication rate was higher than expected, reaching 18%. The overall mortality was lower in the treated group.

Background and Aims: Identifying the risk factors for extraintestinal manifestations (EIMs) in inflammatory bowel diseases (IBD) may optimize the therapeutic decision. We aimed to assess the prevalence of EIMs in IBD patients in Romania and to determine the risk factors., Methods: We analyzed 2,626 patients registered in the Romanian IBD Prospect National Registry. We performed a descriptive cross-sectional study to assess the point prevalence of EIMs, calculating global prevalence and analyzing the different types of EIMs and their respective frequencies were carried out. Demographic and clinical risk factors were researched as possible predictors for EIMs development, based on the results of the univariate and multivariate logistic regression analysis., Results: The overall point prevalence of EIMs was 16.3%. A significantly higher frequency of EIMs in Crohn's disease (CD) was noted in comparison to ulcerative colitis (UC) and IBD unclassified (IBDU) (23.2% vs 11.3% and 16.3%, respectively, p<0.001). The most frequent type of EIM was peripheral arthropathy (8.3%), significantly associated with CD (p<0.001). Univariate analysis highlighted the significant independent common predictive risk factors for EIMs, in both CD and UC patients: female gender, patient's urban area of origin, anemia, hypoalbuminemia, and high level of C-reactive protein (CRP), while significant independent IBD phenotype-related risk factors were ileocolonic location and concomitant involvement of upper gastrointestinal tract for CD, non-smoker status and both moderate and severe disease activity for UC (p<0.05). Multivariate analysis determined that female CD patients with moderate or severe disease activity, with other than isolated ileal disease, and female UC patients with moderate or severe extensive colitis are the most likely to develop EIMs., Conclusions: IBD patients are experiencing EIMs in a large proportion, with higher rates for CD. As EIMs negatively affect patient outcomes, foreseeing the risk by identifying independent and associated predictive factors could be a first step to optimal work-up and treatment.

Patient and liver graft survival rates have improved significantly in the last decades, leading to complications mainly related to long-term immunosuppression. Prevention of, screening for metabolic syndrome, cardiovascular disease, de novo diabetes mellitus, renal dysfunction, and malignancies and their management are mandatory due to important causes of morbidity and mortality in this patient population. Quality of life (QoL) and functional benefits are clearly better compared to preoperative status; however, post-liver transplantation (LT) complications may impair and alter QoL scores. Individualized immunosuppression managed by transplant physicians and collaboration with other non-transplant specialists for recognition and treatment of medical complications and comorbidities after LT is the key to enhanced QoL and life expectancy of this patient population.

Background and Aims: Elimination of hepatitis C worldwide is more feasible if micro-elimination screening strategies are adopted. We aimed to screen hepatitis C virus (HCV) in specific high-risk populations in certain sub-regions of Romania and link them to antiviral treatment., Methods: A multicenter prospective study was conducted among the hospitalized or ambulatory adult patients from March 2019 to March 2020 in more than 20 medical institutions from 4 Romanian cities (Bucharest, Iasi, Timisoara, Cluj-Napoca). A rapid diagnostic test for HCV diagnosis was performed to all admitted patients and the positive ones were sent to gastroenterology departments for confirming the active infection, staging and treatment prescription., Results: In total, 25,141 subjects signed the informed consent and were consequently enrolled into the study. The prevalence of anti-HCV antibodies was 1.39% (95%CI: 1.25-1.54) and increased with the number of risk factors presented by one subject. There was a positive association between the presence of anti-HCV antibodies and female gender (p<0.001), rural area of residence (p<0.001), advanced age (p<0.001), as well as a negative association with the education level (p<0.001)., Conclusions: In a hospital-based screening micro-elimination program in Romania, HCV prevalence was lower than previously reported. This is a first step towards a cost-effective screening in a well-defined group of persons at risk and provides sufficient capacity to deliver access to HCV treatment and linkage to care in Romania.

Background and Aims: Prevalence of malnutrition in inflammatory bowel diseases (IBD) varies between 16% and 75%. Data on the nutritional status at initial diagnosis of ulcerative colitis (UC) or Crohn's Disease (CD) are scarce. It is believed that more than 50% of IBD patients suffer significant weight loss prior to diagnosis. The aims of our study were to assess malnutrition in patients recently diagnosed with IBD and to determine its predictive factors., Methods: We retrospectively included 625 IBD patients registered in the Romanian "IBD Prospect" database between January 2006 and July 2017. All patients were diagnosed within 6 months prior to registration. We defined malnutrition as weight loss of more than 5% of the initial weight during the 3 months prior to registration., Results: There were 361 new cases of UC, 241 CD and 23 cases of unclassified IBD. There was a slight male predominance (M/F=1.2). Prevalence of overall malnutrition was 36.3%. It was significantly more frequent in CD than in UC patients (41.1% vs. 32.4%, p=0.031). In multivariate analysis, malnutrition in UC patients was associated with male gender (p=0.001), more severe disease (p<0.0001) and more extensive disease (p=0.027), while in CD it was associated with younger age (p=0.013) and more severe disease (p<0.0001)., Conclusions: About 1 in 3 newly diagnosed IBD patients presents with malnutrition at the time of diagnosis.

Nonalcoholic liver disease (NAFLD) is a hot topic for gastroenterologists and hepatologists and clinical practitioners must be kept abreast with the rapid progress of knowledge in this field. The Romanian Society of Gastroenterology and Hepatology (RSGH) has elaborated this review dedicated to evidence-based data on pathogenesis, diagnosis and therapy of this condition. The term NAFLD includes two distinct conditions, with different histologic features and prognosis: non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH), the second with the highest risk of evolution to cirrhosis and its complications, including hepatocellular carcinoma (HCC). Non-alcoholic fatty liver disease is considered the hepatic manifestation of the metabolic syndrome. Therefore, NAFLD is associated not only with an increase of liver-related mortality, but also of the overall mortality, especially cardiovascular and malignancies. Noninvasive techniques, such as biological tests and elastography can be used for the evaluation of NAFLD patients. Liver biopsy should be recommended in selected cases, for diagnostic, therapeutic and prognostic purposes. Patients with NAFLD would benefit from their lifestyle changes by progressive weight loss through exercise and low fat and sugar diet. Pharmacotherapy should be reserved for patients with NASH, particularly for those with significant fibrosis. Until now, there are no FDA approved therapies for NASH.

Background and Aims: To evaluate the predictive factors for recurrence of the disease and overall survival (OS) after achieving complete response (CR) in patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE)., Methods: From January 2013 to December 2017, 168 treatment-naïve patients diagnosed with HCC underwent TACE as a first-line therapy and the gathered data was retrospectively reviewed. We determined the predictive factors for complete response (CR), for recurrence after CR and for survival using the Cox proportional hazard model., Results: Median follow-up was 27.4 months (range 4-65 months). The mean patient age was 62.2+/-7.9 years. Eighty-three patients had an α-fetoprotein (AFP) level > 20ng/mL. The median maximal diameter of the tumors was 3.5 cm. Sixty-three patients (37.5%) achieved CR after TACE, and recurrence after CR was detected in 37 patients (58.7%). In multivariate analysis, tumor size ( 25 ng/mL and multiple tumors were demonstrated to have a significant relationship with recurrence after CR, with HRs of 1.650 (p=0.05) and 3.932 (p=0.038), respectively. Increased initial serum AFP > 22 ng/mL, tumor size > 4.5 cm, outside Milan criteria, not receiving a liver transplant and presence of portal vein thrombosis (PVT) were correlated with poor survival., Conclusions: In patients treated with TACE as an initial therapy, tumor size (≤4.5 cm) and single tumor were predictive factors for CR. Multiple nodules and an elevated serum AFP > 25 ng/mL were predictive factors for recurrence after CR. Outside Milan criteria tumors, elevated AFP levels and the presence of PVT were significantly correlated with decreased survival.

Background and Aims: Diverticular disease of the colon is a common clinical condition in developed countries, and is associated with significant (direct and indirect) economic burden. The aim of this Position Paper is to provide clinical guidance for appropriate definition, prevalence, risk factors, diagnosis, and treatment of colonic diverticular disease., Methods: A working group of recognized experts established by the Board of the Romanian Society of Gastroenterology and Hepatology (RSGH) screened the literature and the available guidelines on colonic diverticular disease. Statements were formulated based on literature evidence. These statements were discussed within the working group and decision for each of them was taken by consensus., Results: Thirty two statements were elaborated. The grade of recommendation, according to the level of evidence was established for each statement. Short comments with literature support accompany each statement., Conclusion: This Position Paper represents a practical guide for clinicians dealing with patients affected by colonic diverticular disease.

Background: Nowadays, interferon-free therapy using new direct-acting antivirals (DAA) has dramatically increased the cure rate across different HCV-infected patient populations, including groups traditionally viewed as difficult-to-treat (patients with co-infections, cirrhosis and liver transplant - LT recipients) with marked improvement in safety and tolerability., Aim: To present our experience with DAA therapy in LT recipients, as well as to compare pre- and post-treatment liver stiffness (LS) and noninvasive fibrosis scores., Methods: Our cohort consisted of 89 patients with genotype 1 (GT1) recurrent hepatitis C after LT. Seventy six patients received ombitasvir/paritaprevir/ritonavir+dasabuvir+ribavirin and 13 sofosbuvir/ledipasvir+/-ribavirin. Fibroscan®, FIB4 and APRI scores were performed in all patients before and 12 weeks after DAA therapy., Results: We analyzed 45 (50.5%) males and 44 (49.5%) females with a mean age of 55+/-7.7 years. Median time since LT was 20.9 months. At baseline, 53 (59.6%) of patients had severe necroinflammation at Fibromax®; advanced fibrosis (F3, F4) was encountered in 35 (39.4%) and grade 3 steatosis in 33 (37.1%) of LT recipients. End of therapy (EOT) virological response (VR) was 100%. Sustained virological response 12 weeks after therapy (SVR12) was 97.7% in the intention-to-treat analysis and 100% in per protocol analysis. There was a significant improvement in LS between antiviral therapy initiation and SVR12: 11.9+/-1.05kPa vs 8.8+/-0.6kPa (p<0.0001), as well as in APRI (2.7+/-0.3 vs 0.4+/-0.05, p<0.0001) and FIB4 (4.6+/-0.5 vs 2.5+/-0.2, p<0.0001) scores., Conclusions: In HCV positive recipients, DAA regimens are highly effective and safe. A significant decrease of LS by transient elastography and fibrosis non-invasive scores can be observed after successful therapy.

Background and Aims: Literature data suggest that HCV genotype-1b is present in 93-99% of the Romanian patients infected with hepatitis C virus (HCV). We present the genotyping tests recently performed on patients with HCV and advanced fibrosis eligible for the Direct-Acting Antiviral (DAA) therapy, as well as the prevalence of these cases across Romania., Methods: The genotyping method was performed on 7,421 HCV patients with advanced fibrosis. The detection method was automatic real time PCR platform M2000 (Abbott). Every subject was introduced into a database including age, sex, county and address., Results: Genotype 1b was almost exclusively present: 7,392/7,421 (99.6%). Genotype 1b patients were 19.6% from Bucharest, 49% were males, with a median age of 60 years. Genotype non-1b was encountered in 29/7,421 subjects (0.4%), 62% were males, 69% from Bucharest and the median age was 52 years. Most of the subjects (75%) were in the 6th and 7th age decade. The prevalence of these cases varied significantly across Romanian counties: the highest was in Bucharest (61.3/105), Bihor (47/105), Iasi (46/105) and Constanta (43/105), and the lowest in Ilfov (2.8/105), Harghita (3.7/105), Covasna (5.4/105) and Maramures (8.8/105) (p<0.001)., Conclusions: Genotype 1b is encountered in 99.6% of patients with chronic hepatitis C and advanced fibrosis from Romania. The presence of genotypes non-1b is more common in Bucharest, in males and at a younger age. There are significant differences regarding the distribution of these cases across Romania: the highest rates are in Bucharest, Bihor, Iasi and Constanta.

Background and Aims: Ombitasvir/Paritaprevir/ritonavir/Dasabuvir (OBV/PTV/r+DSV) is one of the elective direct-acting antivirals (DAAs) recommended by international guidelines and the only one covered by the National Insurance System in Romania until November 2016. Our aim was to present the first prospective Romanian cohort evaluating the effectiveness and safety in clinical practice of this 3DAA combination in patients with HCV genotype-1b Child A liver cirrhosis., Methods: 681 patients received OBV/PTV/r+DSV+RBV for 12 weeks and were assessed clinically and biologically at baseline, week 4, 8, 12 (end of treatment, EOT), and 12 weeks after therapy (sustained viral response, SVR)., Results: Per protocol, EOT virological response was 99.8% and SVR12 rate was 99.4%. Adverse events were present in 36.4% of patients. Permanent discontinuation of 3DAA regimen due to side effects was reported in 11 patients (1.6%). In 47.6% (185/389) of patients, Transient Elastography values were >20kPa (defined as clinically significant portal hypertension, CSPH) at baseline. Independent variables associated with CSPH were: baseline cholesterol level (p=0.003), platelet count <120,000/mm³ (p=0.02), MELD score (p=0.01). Liver stiffness measurement has significantly improved between baseline (26.6+/-12.7kPa) and SVR12 (21.6+/-11.8kPa) (p<0.0001). The same was true for APRI score (2.66+/-0.15 at baseline vs 0.85+/-0.02 at SVR12, p<0.0001) and FIB4 score (5.53+/-0.28 vs 3.24+/-0.08, p<0.0001), but not for Lok score (0.57+/-0.01 vs 0.63+/-0.01, p<0.0001)., Conclusions: We report a high efficacy of the 3DAA regimen in a homogeneous compensated HCV genotype-1b liver cirrhosis population, in a real-life setting. Noninvasive fibrosis scores significantly improved at SVR12.

Background and Aims: Hepatitis C virus (HCV) infection is a common condition with endemic prevalence in some areas of the world. In Romania, the mean prevalence is about 3%. New treatments have become available on the market in recent years and new drugs are in the pipeline. A re-evaluation of HCV therapy was considered mandatory. The Romanian Society of Gastroenterology and Hepatology undertook this task for the practitioners of this country., Methodology: A group of recognized experts was created who screened the available literature and the major available guidelines. A list of items requiring attention was created and these were discussed and rated. Decisions were taken by consensus., Recommendations: We present here the second part of the Society's recommendations for chronic HCV infection treatment. An agreement between experts was reached regarding the therapy of the special categories of patients infected with HCV, complications and monitoring of the therapy, follow-up of the patients who reached sustained virologic response and re-treatment of the patients with therapy failure., Conclusions: This Position Paper represents a guide for the assessment and the therapy of HCV infection. The recommendations are in concordance with other guidelines but are applied to real-life conditions in Romania.

Background and Aims: Liver stiffness (LS) measurement by Transient Elastography (TE) has been widely accepted as a tool for fibrosis assessment. The aim of this study was to assess LS dynamics in a group of patients with HCV liver cirrhosis after interferon free treatment (IFT)., Methods: This two-center clinical trial included 225 patients with compensated HCV cirrhosis (all genotype 1b), who received IFT for 12 weeks. All patients were evaluated by means of TE at the beginning and at the end of treatment (EOT), and a subgroup (170 patients) also 12 weeks after EOT; all of them had sustained viral response (SVR). Reliable LS measurements (LSM) were defined as a median value of 10 valid LSM, with IQR <30% and SR >/=60%. Both M and XL probes were used. For diagnosing cirrhosis we used a cut-off value of 12kPa as proposed by the Tsochatzis meta-analysis. We considered a decrease or increase of more than 10% in LSM as being significant., Results: Out of 225 subjects, reliable measurements were obtained in 93.7%, so that the final analysis included 211 patients. The mean LS values decreased significantly after IFT: 26.4+/-11.7 vs. 23.5+/-13.3 kPa (p=0.01). Most patients, 59.2% (125/211) presented more than 10% decrease in LS values, 24.1% (51/211) had stable LS values, while in 16.4% (35/211) cases, the LS values increased. In the subgroup of 170 patients with LSM also performed 12 weeks after EOT (SVR), the mean LS values were significantly lower as compared to baseline: 21.3+/-11 kPa vs. 27.4+/-11.9 kPa (p<0.0001) and also as compared to EOT: 21.3+/-11 kPa vs. 23.7+/-13.3 kPa (p<0.0001)., Conclusion: In our patients with HCV liver cirrhosis, the mean LS values evaluated by TE significantly decreased after antiviral treatment at EOT and also 12 weeks after EOT as compared to baseline. Overall, about 60% of patients had LS values at EOT lower than at baseline, while 12 weeks after EOT about 75% of patients had LS values lower than at baseline.

The recommendations are in concordance with other guidelines but are applied to the real-life conditions in this country.

Introduction: Nonalcoholic fatty liver disease (NAFLD) has an increasing incidence worldwide, reflecting the epidemics of obesity and metabolic syndrome. Data on knowledge, attitude and management by the Romanian gastroenterologists with regard to NAFLD are lacking., Methods: We assessed current diagnostic and treatment patterns of the management of NAFLD among 102 Romanian board certified gastroenterologists using a survey developed to collect information regarding participants' clinical practice, diagnostic tools and usage of medication in patients with NAFLD., Results: 71.6% of the surveyed gastroenterologists (SG) had more than 5 years of gastroenterology practice, were university affiliated and 37.3% had predominant activity in hepatology (>60%). In Romania, 60.8% of the SG would diagnose NAFLD only if all other causes of liver disease were absent. All practitioners use a noninvasive tool for staging NAFLD, 45.1% use both serum markers and transient elastography. Liver biopsy is performed by 61.8% of the SG in the presence of a discordant result in two noninvasive methods of fibrosis evaluation. The most frequently prescribed drugs are: silymarin (88.2%), vitamin E (78.4%) and ursodeoxycholic acid (77.4%)., Conclusion: The results of this survey suggest that clinical practice patterns among Romanian gastroenterologists for the diagnosis (mainly liver biopsy) and management of NAFLD frequently diverge from published practice guidelines. Nonalcoholic steatohepatitis is probably underdiagnosed, especially in patients with normal transaminase levels and is also overtreated with drugs that are not recommended in the guidelines.

Background: Hepatitis delta virus (HDV) infection is associated with accelerated progression of fibrosis, early occurrence of hepatic decompensation and an increased risk for hepatocellular carcinoma. Epidemiological data on hepatitis delta virus (HDV) in Romania are still lacking., Aim: To assess the prevalence, virological, clinical and epidemiological features of HDV infection in Romanian patients., Methods: We conducted a multicenter study in 10 centers. Data on sociodemographic characteristics and potential risk factors were collected through a questionnaire. Virological markers of HBV and HDV infection, biochemical and clinical features of liver disease were evaluated., Results: The study population comprised 2,761 HBsAg(+) patients with a mean age of 43.8+/-13.8 years, out of whom 5.2% were HBeAg(+) and 55.7% were males. Liver cirrhosis was detected in 17.9% of patients, while 80.4% had chronic hepatitis. The prevalence of IgG anti-HDV(+) patients was 23.1%, out of whom 16.4% were HDV RNA positive. The highest prevalence of HDV infection was encountered in patients aged 50-59 years (28.9%) and patients aged >/= 60 (24.8%) (p=0.0001). Seroprevalence of HDV was significantly higher in AgHBs(+) cirrhotics vs. noncirrhotics (43.4% vs 19.0%, p=0.0001). Risk factors for HDV infection were: occupational hazard, no HCV chronic infection, lack of anti-HBV vaccination, presence of blood transfusions, any previous surgery, frequent hospitalization or endoscopies, tattoos, body piercing, use of glass syringes, number of female sexual partners., Conclusions: HBsAg(+) population in Romania is characterized by a high prevalence of HBeAg(-) HBV infection as well as HDV co-infection. A cohort phenomenon for HDV prevalence is also observed similar to that of HCV/HBV monoinfections.

In assessing exocrine pancreatic insufficiency (EPI), its diverse etiologies and the heterogeneous population affected should be considered. Diagnosing this condition remains a challenge in clinical practice especially for mild-to-moderate EPI, with the support of the time-consuming breath test or the coefficient of fat absorption. The fecal elastase-1 test, less precise for the diagnosis, cannot be useful for assessing treatment efficacy. Pancreatic enzyme replacement therapy (PERT) is the mainstay of treatment, whereby enteric-coated mini-microspheres are taken with every meal, in progressive doses based on an individual's weight and clinical symptoms. The main indication for PERT is chronic pancreatitis, in patients who have clinically relevant steatorrhea, abnormal pancreatic function test or abnormal function tests associated with symptoms of malabsorption such as weight loss or meteorism. While enzyme replacement therapy is not recommended in the initial stages of acute pancreatitis, pancreatic exocrine function should be monitored for at least 6-18 months. In the case of unresectable pancreatic cancer, replacement enzyme therapy helps to maintain weight and improve overall quality of life. It is also indicated in patients with celiac disease, who have chronic diarrhea (in spite of gluten-free diet), and in patients with cystic fibrosis with proven EPI.

Background and Aims: Anemia is the most frequent systemic complication in inflammatory bowel diseases. It affects the quality of life and can interact with working capacity. Our objectives were to identify the prevalence of anemia, its main causes and its management in patients with inflammatory bowel disease from Romania., Methods: We conducted a multicenter prospective study from March 2013 to August 2014. We enrolled 291 patients from three referral centers: 115 (39.52%) with Crohn's disease (CD) and 176 (60.48%) with ulcerative colitis (UC). We defined anemia according to the WHO criteria., Results: Median age of the patients was 41 years and the median time period since diagnosis was 3 years (0.75-7). The median activity index for UC (UCAI) was 4 and the median CD activity index (CDAI) was 96. More patients with CD were on antiTNFα therapy (p < 0.01), corticosteroids (p =0.18) or azathioprine (p=0.05) and required surgery for their underlying disease at study enrollment (p < 0.01). Anemia was present in 31.27% of the patients, more often in those with CD (35.65%) than with UC (28.41%) (not statistically significant); 53.26% of the patients had iron deficiency while 4.12% had folic acid and 8.59% vitamin B12 deficiency; 9.62% of the patients had received anti-anemic therapy at inclusion in the study or in the last three months prior to study enrollment., Conclusions: About one in three Romanian patients with inflammatory bowel disease has anemia, which is frequently associated with iron deficiency. About 30% of the patients with anemia are under therapy and the most frequent route for iron supplementation is the oral one. This might contribute to the high prevalence of iron deficiency and the low level of compliance.

Background: A number of high quality randomized clinical trials examining the efficacy and safety of triple therapy in genotype-1 HCV-infected patients have been published. However, these trials included a small number of patients with advanced fibrosis, and selected a population different from that in real-world settings., Aim: To determine the efficacy of boceprevir, pegInterferon and ribavirin regimen in genotype-1 treatment-experienced HCV-infected patients with cirrhosis and bridging fibrosis in real-life setting., Method: 167 treatment-experienced patients (85.6% relapsers) out of which 33.5% had cirrhosis, with a mean age of 52.6 years, registered in the Romanian Name Patient Program Database were included into the study., Results: 16.7% of patients had a viral load >100 IU/mL. Undetectable HCV RNA was encountered in 77.3% of patients at week 12. Multiple logistic regression analysis revealed the following independent predictors, measured at week 8, for an HCV RNA ≥100 IU/mL at week 12 of triple therapy: alanine aminotransferase values (p=0.01), hemoglobin level (p=0.04) and <2 log drop of viral load (p<0.0001). A stopping score at 8 weeks was created as the sum of these 3 parameters, with a total of 4 possible points. AUROC of this score was 0.84, with a sensitivity of 75% and a specificity of 86.2%., Conclusion: Triple therapy in this cohort of real-life genotype-1 HCV-infected patients with advanced fibrosis showed robust early virological response (EVR) rates. A week 8 model predicting lack of EVR was created, with good clinical utility that can be validated in prospective larger cohorts.

Aim: The aim of the present study was to characterize the dynamics of the Romanian waiting list (WL) for liver transplantation (LT) over two periods: 2004-2007 vs. 2008-2011., Methods: 1,085 patients listed for LT during the time period 2004-2011 were included in our analysis., Results: Death on the WL was significantly higher before 2008 (37% vs. 26.4%, p=0.0001) and risk of dying while on WL was 60% higher. Waiting time on the WL was 75% longer and time until LT was 102% longer before 2008 compared to the second time period (p=0.0001). After 2008, 62.3% of patients were listed for LT with Child Pugh class C compared to 22.1% before 2008 (p<0.0001)., Conclusion: A significant reduction of mortality has been registered on the Romanian WL for LT after 2008, despite the increased severity of liver disease in patients listed for LT.

Aim: This is a retrospective study of patients with advanced biliary tract carcinoma (BTC), who were treated with different regimens of chemotherapy., Methods: We studied patients with advanced BTC registered at the Department of Oncology at the Fundeni Clinical Institute between 2004 and 2008. The following data were analyzed: rate of response, progression free survival (PFS) to first and second line of chemotherapy, overall survival (OS) and drug toxicity. Ninety-six patients were eligible having either advanced intra or extrahepatic cholangiocarcinoma, or gallbladder cancer with no prior chemotherapy., Results: Out of 96 patients, 57 (59.4%) received fluoropyrimidines (FP)+cisplatin and 39 (40.6%) gemcitabine (Gem)+/-cisplatin. The median PFS for FP+cisplatin was 5.9 months (95%CI 5-6.9) and for Gem+/-cisplatin 6.3 months (95%CI 5.4-7.1), p=0.661. Median OS for FP+cisplatin was 10.3 months (95%CI 7.5-13.1) and for Gem+/-cisplatin 9.1 months (95%CI 7.0-11.2), p=0.098. On disease progression, 46 patients received second line CT (Gem or FP+/-platinum compounds). Median OS for patients with FP based first line and Gem+/-cisplatin in second line was 19 months (95%CI 8.9-29) higher than for the reverse sequence: 13.2 months (95%CI 12-14.4), but not statistically significant (p=0.830). All patients were evaluated for toxicities. Most patients (75.5%) reported at least one adverse event., Conclusion: Our results through direct comparison of FP+cisplatin with Gem+/-cisplatin as first line treatment did not show any statistical differences in terms of rate of response, PFS and OS. However, our study showed that FP+cisplatin as first line and Gem based second line therapy gave a better OS rate.

Background and Aim: Wilson's disease (WD) is a rare autosomal recessive disease. More than 500 mutations have been described so far, out of which 29 in exon 14. H1069Q mutation in the exon 14 of ATP7B gene is the most frequently encountered in Europe. The aim of the present study was to evaluate the incidence of mutations occurring in exon 14 of ATP7B gene in Romanian patients referred to a tertiary gastroenterology center, with known or suspected WD and in asymptomatic first degree relatives of index cases., Methods: 93 patients were included in the study. Exon 14 of ATP7B gene has been amplified by PCR from genomic DNA and mutations identified by sequencing., Results: Only H1069Q missense mutation was detected in our study group. In patients with an established diagnosis of WD (38 cases), 34.2% were heterozygous for H1069Q and 21.1% were homozygous, with an allelic frequency of 38.1%. In paediatric WD patients (12 cases) 25% were heterozygous and 16.7% were homozygous (not significant versus adult population). Among asymptomatic first degree relatives of patients with WD (12 siblings, 25 parents) there were 40.5% cases heterozygous for H1069Q. In patients with suspected WD (17 cases), only 5.9% were heterozygous and no homozygous patient was identified. In our study group, H1069Q screening alone could not raise the Leipzig score to confirm diagnosis in patients with suspected WD or in asymptomatic first degree relatives., Conclusion: H1069Q mutation is highly prevalent in Romanian WD patients and first degree relatives, similar to other central and continental western European populations.

We present the case of a previously healthy 62 year old man who developed primary non-Hodgkin lymphoma of the liver. Biopsy confirmed that it was a diffuse large anaplastic T-cell lymphoma of an extremely rare type. The diagnosis of this type of lesions is suggested by the presence of a hepatic mass without lymphadenopathy, splenomegaly or bone marrow involvement associated with normal tumor markers (carcinoembryonic antigen, alpha-fetoprotein and CA 19-9 levels). Histological examination of tissue is essential to confirm the diagnosis. Treatment options are surgical resection and/or chemotherapy but the rate of response to treatment varies widely. Some patients can achieve prolonged remission.

Background and Aims: Serological markers have been widely used for diagnostic purposes and disease stratification in inflammatory bowel diseases (IBD). The aim of this study was to investigate the seroprevalence and the correlations of anti-Saccharomyces cerevisiae antibodies (ASCA) titers with different clinical phenotypes in Romanian patients with Crohn's disease (CD)., Methods: The study included 107 CD and 86 ulcerative colitis (UC) patients from the Gastroenterology Departments of three University Hospitals, and 60 healthy subjects. ASCA IgA and IgG titers were determined using ELISA test. For CD patients the phenotype was established according to the Montreal classification. The differences in ASCA titers for different CD phenotypes were assessed using the Mann-Whitney U test., Results: ASCA prevalence was 33.6% in CD group, 12.8% in UC group and 6.6% in the control group. Significantly higher IgA (p=0.05) and IgG (p=0.03) titers were found in patients from the Montreal A1+A2 groups (age at onset below 40) compared with the older patients (A3). Higher titers were found in patients with extensive ileo-colonic lesions (L3) and upper gastrointestinal tract involvement (L4) than in patients having only colonic disease (L2). Significantly higher IgA (p=0.03) and IgG (p=0.03) titers were observed in patients with stenosing (B2) and penetrating (B3) disease compared with the nonstricturing, nonpenetrating (B1) phenotype. No correlation between ASCA titers and disease duration was found., Conclusion: ASCA seropositivity in Romanian CD patients is lower than in Western Europe. Higher ASCA IgA and IgG titers are associated with a younger age at diagnosis and more aggressive phenotypes.

Background: Antiviral therapy for chronic hepatitis D (delta) is not yet satisfactory, although it appears to be the only means to alter the progressive natural course of chronic hepatitis D virus (HDV) infection., Aim: To assess safety and efficacy, evaluated by virological, biochemical and histological end-of-treatment (EOT) and end-of-follow-up (EOF) response to peg-interferon α-2b 1.5 µg/kg body weight weekly in a Romanian cohort of naïve patients with chronic hepatitis delta., Results: 49 Caucasian patients (55.1% men, 44.9% females) with a mean age of 37.95 years received study medication; per-protocol population consisted of 36 subjects. Virological EOT response was present in 33.3% and EOF response was maintained in 25% of patients. 50% of study population showed normalization of ALT level at EOT and 25% at EOF. A combined biochemical and virological response was observed in 19.4% of patients at EOT and in 16.7% at EOF. At baseline, the necroinflammation quantified by histological activity index (HAI) score was 9.72 and the mean fibrosis score was 2.03; there was a significant decrease of HAI score to 7.44 (p=0.01) at EOT, but not for fibrosis score (1.33, p=0.37). However, only 8.3% of patients at EOT and 19.4% at EOF had progressive histological disease., Conclusions: Treatment with peg-interferon α-2b succeeded in obtaining a negative HVD RNA in 25% of patients after 104 weeks of follow-up, although combined biochemical and virological response was present in only 16.7%. Necroinflammation decreased significantly in treated patients. Longer treatment periods with pegylated interferon or combination regimen peg interferon-nucleotide analogues should be tested in order to increase efficacy.

The assessment of tissue healing has emerged as an important treatment goal in patients with inflammatory bowel disease. In patients with ulcerative colitis (UC), mucosal healing may represent the ultimate therapeutic goal due to the fact that the inflammation is limited to the mucosal layer. Mucosal and histological healing may indicate a subset of UC patients in long-term clinical, endoscopic and histological remission in whom immunomodulators, biologics, and even aminosalicylates may be withdrawn. Confocal laser endomicroscopy allows the assessment of residual cellular inflammation, crypt and vessel architecture distortion during ongoing endoscopy, and therefore permits a real-time evaluation of histological healing in patients with ulcerative proctitis. Images of conventional optical microscopy and confocal laser endomicroscopy in patients with ulcerative proctitis in remission are presented.

Introduction: Chronic HCV infection represents a public health problem in Romania, with a prevalence of 3.23-4.56%, and more than 5,000 patients on the waiting lists for antiviral therapy., Aim: To perform an evaluation of the severity of chronic HCV infection genotype 1b, and a quantification of patients with a low viral load, in order to quantify the number of patients who may be considered for shortened treatment duration., Material: Histological assessment and viral load were performed in 1,220 consecutive patients from the waiting list for antiviral therapy in 2009. The severity of chronic hepatitis was assessed by histological evaluation (the necrotic-inflammatory index - Metavir and the fibrosis score - Metavir). Viral load was measured by PCR and 400,000 UI/ml and 600,000 UI/ml were defined as thresholds for low versus high viral load We assessed the influence of age, sex, and viral load on necro-inflammatory activity and fibrosis., Results: The mean age of the patients included was 48 ± 10.69 years and females predominated (58%). Many of them (60%) were in stage F3, with a high potential for disease progression in the next 10 years (necro-inflammatory activity was moderate to severe in over 90%). Almost half of the patients had low viral load, below 600,000 copies/ml. The viral load was significantly associated with the age (p< 0.001) and sex (p< 0.001) of the patients., Conclusion: Chronic HCV hepatitis in patients on the waiting lists for antiviral therapy in Romania has a high severity with important predictable consequences on the duration of life, complications and treatment costs. The strategy of shortening the duration of treatment would be beneficial for almost 50% of the patients.

Aims: This study was aimed at determining the seroprevalence of hepatitis C virus (HCV) infection in Romania and the possible risk factors and modality of HCV transmission., Methods: A nationwide cross-sectional survey among the adult population was conducted between 2006-2008 in Romania through a population multicenter stratified random cluster sampling. Serum samples from 13,460 subjects were tested with a 3rd generation ELISA and a standardized questionnaire concerning the socio-demographic characteristics and potential risk factors was used., Results: The prevalence rate of HCV infection in Romanian adult population was 3.23% with significant differences between the main geographical regions (Moldavia 4.25%, Wallachia & Dobrogea 3.35% and Transylvania & Banat 2.63%), as well as between different counties (maximum 7.19%, minimum 0.56%). Overall participation rate to the survey of the selected subjects was 74.69%. Risk factors for HCV infection were: blood/blood products transfusions (p=0.0001), previous surgery (elective and emergency, p=0.0001 and p=0.043, respectively), frequent hospitalizations (p=0.0001), injections at home (p=0.0001), accidents/trauma (p=0.0001), occupational hazard related to blood exposure (p=0.025), intravenous drug administration (p=0.002), a partner chronically infected with HCV/hepatitis B virus (HBV) (p=0.046), first sexual intercourse <18 years (p=0.019), familial exposure to HCV/HBV infection (p=0.001) or to chronic HBV/HCV liver disease (p=0.001), personal history of chronic HBV infection (p=0.001). HCV RNA positivity was detected in 91% of the anti HCV positive subjects., Conclusions: Overall HCV prevalence in Romania is 3.23%. Both nosocomial and non-nosocomial routes are implicated as risk factors for HCV infection.

Background and Aim: The current standard of care in chronic HCV genotype 1 hepatitis is the combination of pegylated interferon (PegIFN) with ribavirin for 48 weeks. The aim of our paper was to verify if there are significant differences regarding the sustained virologic response (SVR) in patients treated with PegIFN alfa-2a vs. those treated PegIFN alpha-2b, both in combination with ribavirin., Method: We performed a retrospective study on 507 patients with chronic viral C hepatitis treated with PegIFN alpha-2a 180 microg/kg/week or PegIFN alpha-2b 1.5 microg/kg/week plus ribavirin in the recommended doses according to weight, following the current treatment guidelines. We evaluated the SVR defined as PCR RNA-HCV undetectable 24 weeks after the end of treatment., Results: There were no differences regarding the baseline characteristics among the subgroups of patients treated with PegIFN alpha-2a or PegIFN alpha-2b concerning the pretreatment viral load (p=0.2445), the severity of fibrosis (p=0.2403), the mean age of the patients (p=0.9597) and the women/men ratio (p=0.2087). The SVR rates in patients treated with PegIFN alpha-2a were similar to those in patients treated with PegIFN alpha-2b: 208/338 (61.5%) vs. 94/169 (55.6%) (p=0.2129)., Conclusion: Sustained virologic response rates were similar in HCV genotype 1 patients treated with PegIFN alpha-2a and with Peg-IFN alpha-2b.

Background: An overall prevalence rate of HCV infection in Romanian adult population was recently estimated to be 3.23%. The proportion of treated patients with chronic hepatitis C in our country has never been assessed., Aims: 1) to analyze the quality and quantity of antiviral therapy delivery; 2) to determine the proportion of patients being annually and ever treated with antiviral therapy in Romania and 3) to identify barriers against treatment of HCV infected-population in Romania., Results: The number of annually treated patients remained relatively stable between 2002 and 2007 (1,813 patients treated with pegylated interferon and ribavirin in 2002 and 2,446 in 2007). There was a doubled increase in reimbursed treatment in 2008 and 2009 (4,503 and respectively 4,701 treated patients) due to a special campaign organized to increase awareness and prevention of HCV transmission. The median time to therapy approval varies from county to county; overall it is 10.23 months. A total number of 25,318 patients with chronic C hepatitis were treated between 2002-2009, corresponding to a cumulative proportion of 4.1% of the prevalent cases of HCV infection treated in Romania until 1st January 2010. The main limiting factor of access to antiviral therapy for hepatitis C in Romania remains the lack of funds., Conclusions: This is the first analysis of the nationwide practice for treatment of hepatitis C in Romania. Increased public health efforts are required to improve access to antiviral therapy for hepatitis C in Romania.

Background: Small nodules (under 3 cm) detected on ultrasound (US) in cirrhotics represent the most challenging category for noninvasive diagnosis of hepatocellular carcinoma (HCC)., Aim: To evaluate real-time sonoelastography as a noninvasive tool for the diagnosis of small HCC nodules in cirrhotic patients., Methods: 42 cirrhotic patients with 58 nodules (1-3 cm) were evaluated with real-time elastography (Hitachi EUB-6500); the mean intensity of colors red, blue, green were measured using a semi-quantitative method. Analysis of histograms for each color of the sonoelastography images was performed for quantifying the elasticity of nodule tissue in comparison with the cirrhotic liver tissue. AUROC curves were constructed to define the best cut-off points to distinguish malignant features of the nodules. Univariate and multivariate logistic regression analysis was performed., Results: 595 sonoelastography images from 42 patients (25 men; 17 women) were analyzed. The mean age was 56.4 +/- 0.7 years and 69% patients were in Child-Pugh class A, 19% class B, 11% class C. For the mean intensity of green color AUROC=0.81, a cut-off value under 108.7 being diagnostic for HCC with a Sp=91.1%, Se=50%, PPV=92.1%, NPV=47.1%. Mean intensity of blue color proved to be an excellent diagnostic tool for HCC (AUROC=0.94); for a cut-off value greater than 128.9, Sp=92.2%, Se=78.9%, PPV=95.4%, NPV=68%. Independent predictive factors of HCC for a small nodule in cirrhotic patients were: blue color over 128.9 at sonoelastography and hypervascular appearance at Doppler US., Conclusions: US elastography is a promising method for the non-invasive diagnosis of early HCC. Blue color at elastography and hypervascular aspects are independent predictors of HCC.
