High prevalence of muscle weakness and probable sarcopenia in patients with inflammatory bowel disease.

BACKGROUND: This study aimed to determine the prevalence of probable sarcopenia and sarcopenia in patients with inflammatory bowel disease (IBD) by using the European Working Group on Sarcopenia in Older People (EWGSOP2) diagnostic criteria. METHODS: Sarcopenia was assessed by using the sequential four-step algorithm. (1) Find: Sarcopenia risk by simple clinical symptom index (strength, assistance walking, rise from a chair, climb stairs, and falls [SARC-F questionnaire]). (2) Assess: Probable sarcopenia by low muscle strength on handgrip. (3) Confirm: Confirmed sarcopenia by low appendicular skeletal muscle mass on bioimpedance analysis. (4) Severity: Severe sarcopenia by low 4-m gait speed test. RESULTS: A total of 129 adult patients with IBD younger than 65 years and 50 age- and sex-matched healthy control (HC) participants were included to the study. Handgrip strength, gait speed, and SARC-F scores were significantly lower in patients with IBD than in the HCs (P = 0.032, <0.0001, and <0.0001, respectively). Based on the EWGSOP2 definition, 17.8% of patients with IBD had probable sarcopenia, and six patients had confirmed sarcopenia. According to the ethnicity-based population thresholds, 34.9% of patients with IBD had probable sarcopenia, and two patients had confirmed sarcopenia. Corticosteroid use within the past year was identified as an independent risk factor for low muscle strength (P = 0.012; odds ratio, 4.133), along with advanced age and disease activity. CONCLUSION: One-third of the patients younger than 65 years with IBD had probable sarcopenia, defined as low muscle strength, whereas the incidence of confirmed sarcopenia remained relatively low.

Predicting fibrosis progression in non-alcoholic fatty liver disease patients using the FAST Score: A paired biopsy study.

Background and Aim: This study aimed to investigate the predictive value of various non-invasive scores for identifying the progression of hepatic fibrosis over time in patients with Non-Alcoholic Fatty Liver Disease (NAFLD). Materials and Methods: We examined 69 patients with NAFLD who had undergone two liver biopsies at an average interval of 21.3±9.7 months. Progression and regression of fibrosis were defined as an increase or decrease of at least one stage in fibrosis between the initial and follow-up biopsies, respectively. The Fibrosis-4 Index (FIB-4), NAFLD Fibrosis Score (NFS), Agile 3+, Agile 4, and FibroScan-AST (FAST) scores were calculated at the initial biopsy. Results: Comparison of paired biopsies revealed that 45% of participants (n=31) exhibited no change in fibrosis stages, 26% (n=18) experienced progression, and 29% (n=20) demonstrated regression. Multivariable logistic regression analysis identified the FAST score as the only independent predictor of progressive fibrosis, with the odds increasing by 19% (95% CI: 8-38%, p<0.05) for each unit increase in the FAST score at the initial biopsy. No independent predictors for fibrosis regression were identified. Conclusion: Higher baseline FAST scores were associated with an increased likelihood of fibrosis progression, independent of other variables. Thus, the FAST score could serve as both a diagnostic and prognostic tool for fibrosis in patients with NAFLD.

Cannulation rates and technical performance evaluation of commericially available single-use duodenoscopes for endoscopic retrograde cholangiopancreatography: A systematic review and meta-analysis.

BACKGROUND: Single use duodenoscopes were developed to reduce the risk of infection transmission from contaminated reusable duodenoscopes. To this end, we examined various biliary interventions using single use duodenoscopes in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Medline, Embase, Scopus, and Cochrane databases were searched from inception through Aug 2022 to identify studies reporting on the performance of single use duodenoscopes for ERCP. RESULTS: Seven articles were included in the final analysis that included 642 patients (318 males). The Exalt Model D duodenoscope was used in most cases (88.8%) followed by the aScope Duodeno (11.2%) for ERCP. Most ERCPs had a complexity grade of 2 (n = 303) and 3 (n = 198). The pooled cumulative rate of successful cannulation was 95% (95% Confidence Interval (CI): 93-96%, I2=0%, P = 0.46). Sphincterotomy was successfully performed in all cases. The pooled cumulative rate of PEP was 2% (95% CI: 0.4-3.4%, I2=0%, P = 0.80). The pooled cumulative rate of total adverse events was 7% (95% CI: 4-10%, I2=47%, P = 0.08). CONCLUSIONS: The results of this systematic review and meta-analysis show that single use duodenoscopes are associated with high cannulation rates, technical performance, and safety profile.

Chronotype preference, sleep quality, and night-eating behaviors in patients with metabolic dysfunction-associated steatotic liver disease: Assessing the relationship with disease severity and fibrosis.

Background and Aim: Our primary objective is to examine the variance in chronotype, night-eating patterns, and sleep quality in patients with biopsy-proven metabolic dysfunction-associated steatotic liver disease. In addition, we aim to establish a correlation between these variables and the severity of the disease and fibrosis. Materials and Methods: Patients who were following up with biopsy-proven metabolic dysfunction associated steatotic liver disease (MASLD) were included in the study. Histologically severe disease is characterized by a Steatosis, Activity, and Fibrosis activity score of ≥3 or the presence of advanced fibrosis (≥F3). Participants who met the inclusion criteria were given the Morningness and Evening Questionnaire (MEQ), the Pittsburgh Sleep Quality Index, and the Night Eating Questionnaire to complete. Results: A total of 93 patients were included in this study. According to the MEQ, 48 patients were morning type (51.6%), and 42 (45.2%) were neither type. Sleep quality was determined to be inferior in the non-morningness group (p=0.002). A significantly higher proportion of patients with nocturnal eating syndrome had a non-morningness chronotype preference (n=22, 23.7%), compared to those with a morningness chronotype (n=9, 9.7%) (p=0.001). In the multivariate analysis, both age and poor sleep quality had significant impacts on advanced fibrosis, with odds ratios of 1.11 and 3.81, respectively. Conclusion: Despite the non-morningness chronotype demonstrating poorer sleep quality and a higher prevalence of night-eating behavior, our findings revealed no statistically significant differences in terms of sleep quality, nocturnal eating habits, or chronotype preferences among patients with varying degrees of MASLD severity. On the other hand, advanced fibrosis was significantly impacted by poor sleep quality.

Practical guideline on obesity care in patients with gastrointestinal and liver diseases - Joint ESPEN/UEG guideline.

BACKGROUND: Patients with chronic gastrointestinal disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean gastrointestinal patients. The present guideline addresses this question according to current knowledge and evidence. OBJECTIVE: The present practical guideline is intended for clinicians and practitioners in general medicine, gastroenterology, surgery and other obesity management, including dietitians and focuses on obesity care in patients with chronic gastrointestinal diseases. METHODS: The present practical guideline is the shortened version of a previously published scientific guideline developed according to the standard operating procedure for ESPEN guidelines. The content has been re-structured and transformed into flow-charts that allow a quick navigation through the text. RESULTS: In 100 recommendations (3× A, 33× B, 24 × 0, 40× GPP, all with a consensus grade of 90% or more) care of gastrointestinal patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially metabolic associated liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician. CONCLUSION: The present practical guideline offers in a condensed way evidence-based advice how to care for patients with chronic gastrointestinal diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

Evaluation of the effectiveness of drug-eluting transarterial chemoebolization in hepatocellular carcinoma.

Background and Aim: Transarterial Chemoembolization (TACE) therapy is currently considered as first option therapy in the intermediate stage HCC. The purpose of our study is to assess the efficacy and prognostic factors related to the DEB- TACE therapy. Materials and Methods: The data from 133 patients with unresecetable HCC who were treated with DEB-TACE and followed between January 2011-March 2018 were retrospectively evaluated. To assess the efficacy of therapy, control imagings were performed at 30th and 90th days after the procedure. Response rates, survival outcomes, and prognostic factors were investigated. Results: According to the Barcelona staging system, 16 patients (13%) were in the early stage, 58 patients (48%) were in the intermediate stage and 48 patients (39%) were in the advanced stage. There were complete response (CR) in 20 patients (17%), partial response (PR) in 36 patients (32%), stable disease (SD) in 24 patients (21%) and progressed disease (PD) in 35 (30%) patients. Median follow-up time was 14 months (range 1-77 months). Median PFS and OS were 4 months and 11 months, respectively. In multivariate analysis, posttreatment AFP ≥400 ng/ml was found to be an independent prognostic factor on both PFS and OS. Child-Pugh classification and tumor size >7 cm were independent prognostic factors on OS. Conclusion: DEB-TACE is effective and a tolerable treatment method for unresectable HCC patients.

Biologic Therapy Carries a Very Low Risk of Reactivation in Hepatitis B Surface Antigen-Negative Phase of Hepatitis B.

BACKGROUND: The risk of hepatitis B reactivation in hepatitis B surface antigen-negative phase of hepatitis B virus-infected patients exposed to biologic agents is not clear. We aimed to investigate the reactivation rate in hepatitis B surface antigen-negative phase of hepatitis B virus-infected patients after biologic therapy. METHODS: Patients followed at gastroenterology, rheumatology, and dermatology clinics with a diagnosis of immune-mediated inflam matory diseases were screened. Immune-mediated inflammatory diseases patients exposed to biologic agents with a negative hepatitis B surface antigen and positive hepatitis B core immunoglobulin G antibody were included in the study. RESULTS: We screened 8266 immune-mediated inflammatory disease patients, and 2484 patients were identified as exposed to biologic agents. Two hundred twenty-one patients were included in the study. The mean age was 54.08 ± 11.69 years, and 115 (52.0%) patients were female. The median number of different biologic subtype use was 1 (range: 1-6). The mean biologic agent exposure time was 55 (range: 2-179) months. One hundred and fifty-two (68.8%) patients used a concomitant immunomodulatory agent, and 84 (38.0%) patients were exposed to corticosteroids during biologic use. No hepatitis B reactivation with a reverse seroconversion of hepatitis B surface antigen positivity was seen. Antiviral prophylaxis for hepatitis B was applied to 48 (21.7%) patients. Hepatitis B virus-DNA was screened in 56 (25.3%) patients prior to the biologic exposure. Two patients without antiviral prophylaxis had hepatitis B virus-DNA reactivation with a negative hepatitis B surface antigen during exposure to the biologic agent. CONCLUSION: We found 2 reactivations and no hepatitis B surface antigen seroconversion in our cohort. Antiviral prophylaxis for patients exposed to biologic agents may need to be discussed in more detail.

Improving the Computer-Aided Estimation of Ulcerative Colitis Severity According to Mayo Endoscopic Score by Using Regression-Based Deep Learning.

BACKGROUND: Assessment of endoscopic activity in ulcerative colitis (UC) is important for treatment decisions and monitoring disease progress. However, substantial inter- and intraobserver variability in grading impairs the assessment. Our aim was to develop a computer-aided diagnosis system using deep learning to reduce subjectivity and improve the reliability of the assessment. METHODS: The cohort comprises 11 276 images from 564 patients who underwent colonoscopy for UC. We propose a regression-based deep learning approach for the endoscopic evaluation of UC according to the Mayo endoscopic score (MES). Five state-of-the-art convolutional neural network (CNN) architectures were used for the performance measurements and comparisons. Ten-fold cross-validation was used to train the models and objectively benchmark them. Model performances were assessed using quadratic weighted kappa and macro F1 scores for full Mayo score classification and kappa statistics and F1 score for remission classification. RESULTS: Five classification-based CNNs used in the study were in excellent agreement with the expert annotations for all Mayo subscores and remission classification according to the kappa statistics. When the proposed regression-based approach was used, (1) the performance of most of the models statistically significantly increased and (2) the same model trained on different cross-validation folds produced more robust results on the test set in terms of deviation between different folds. CONCLUSIONS: Comprehensive experimental evaluations show that commonly used classification-based CNN architectures have successful performance in evaluating endoscopic disease activity of UC. Integration of domain knowledge into these architectures further increases performance and robustness, accelerating their translation into clinical use.

Significant Differences in IBD Care and Education across Europe: Results of the Pan-European VIPER Survey.

BACKGROUND: Inflammatory bowel disease (IBD) care and education might differ around Europe. Therefore, we conducted this European Variation In IBD PracticE suRvey (VIPER) to investigate potential differences between countries. METHODS: This trainee-initiated survey, run through SurveyMonkey®, consisted of 47 questions inquiring basic demographics, IBD training, and clinical care. Results were compared according to gross domestic product (GDP) per capita, for which countries were divided into 2 groups (low/high income, according to the World Bank). RESULTS: The online survey was completed by 1,285 participants from 40 European countries, with a majority of specialists (65.3%) working in academic institutions (50.4%). Significant differences in IBD-specific training (55.9% vs. 38.4%), as well as availability of IBD units (58.4% vs. 39.7%) and multidisciplinary meetings (73.2% vs. 40.1%), were observed between respondees from high and low GDP countries (p < 0.0001). In high GDP countries, IBD nurses are more common (85.9% vs. 36.0%), also mirrored by more nurse-led IBD clinics (40.6% vs. 13.7%; p < 0.0001). IBD dieticians (33.4% vs. 16.5%) and psychologists (16.8% vs. 7.5%) are mainly present in high GDP countries (p < 0.0001). In the current COVID era, telemedicine is available in 73.2% versus 54.1% of the high/low GDP countries, respectively (p < 0.0001). Treat-to-target approaches are implemented everywhere (85.0%), though access to biologicals and small molecules differs significantly. CONCLUSION: Much variability in IBD practice exists across Europe, with marked differences between high and low GDP countries. Further work is required to help address some of these inequalities, aiming to improve and standardize IBD care and training across Europe.

Presence of axial spondyloarthritis associated sacroiliitis and structural changes on MR enterography: A direct comparison with sacroiliac joint MRI.

INTRODUCTION: To investigate the acute inflammatory and structural changes of sacroiliitis as auxiliary findings on magnetic resonance enterography (MRE) and their presence on closely timed conventional magnetic resonance imaging of the sacroiliac joint (SI joint MRI). MATERIALS AND METHODS: We screened axial spondyloarthritis patients for the simultaneous presence of MREs and SI joint MRIs. Two blinded radiologists evaluated SI joint MRIs and MREs on two separate occasions. We used the Assessment of SpondyloArthritis International Society (ASAS)/Outcome Measures in Rheumatology Network (OMERACT) definitions for SI joint MRI. We implemented previously published standard definitions for osteitis, erosion, sclerosis, and fatty infiltration of SI joint in MREs that contain T1w and T1w post-gadolinium sequences. RESULTS: SI joint MRI and MRE images were present in 43 patients. The median time between the two modalities was 14 (0-89) days. Twelve patients had ASAS-defined positive SI joint MRI. Radiologist-1 and radiologist-2 detected osteitis on MRE in nine and eight out of these 12 patients, respectively. The two radiologists detected ankylosis and fatty metaplasia with a complete agreement and sclerosis with an almost perfect agreement. Both radiologists agreed on erosions on SI joint MRI in the same 10 cases. Radiologists did not identify acute inflammatory or structural changes on MRE in patients with a negative SI joint MRI for these lesions. CONCLUSION: Along with intestinal findings, additional reporting of acute inflammatory and structural changes of the SI joint on a MRE is valuable and may alert physicians to the presence of previously not diagnosed axial spondyloarthritis.

European guideline on obesity care in patients with gastrointestinal and liver diseases - Joint European Society for Clinical Nutrition and Metabolism / United European Gastroenterology guideline.

BACKGROUND: Patients with chronic gastrointestinal (GI) disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean GI patients. The present guideline addresses this question according to current knowledge and evidence. OBJECTIVE: The objective of the guideline is to give advice to all professionals working in the field of gastroenterology care including physicians, surgeons, dietitians and others how to handle patients with GI disease and obesity. METHODS: The present guideline was developed according to the standard operating procedure for European Society for Clinical Nutrition and Metabolism guidelines, following the Scottish Intercollegiate Guidelines Network grading system (A, B, 0, and good practice point [GPP]). The procedure included an online voting (Delphi) and a final consensus conference. RESULTS: In 100 recommendations (3x A, 33x B, 24x 0, 40x GPP, all with a consensus grade of 90% or more) care of GI patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially fatty liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician. CONCLUSION: The present guideline offers for the first time evidence-based advice how to care for patients with chronic GI diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

Evaluation of the Impact of Metabolic Syndrome on Fibrosis in Metabolic Dysfunction-Associated Fatty Liver Disease.

BACKGROUND: Metabolic syndrome (MS) is a condition that consists of several disorders, and the individual impact of these disorders on metabolic dysfunction-associated fatty liver disease (MAFLD) is still not clear in a combined diagnosis of MS. In this study, we aimed to investigate the effect of MS on advanced fibrosis in patients with MAFLD. METHODS: We recruited the patients from our gastroenterology out-patient clinic who were being followed up for MAFLD. MAFLD was diagnosed with liver biopsy in all patients. The frequency of MS and other metabolic parameters were also compared between groups with advanced fibrosis and groups in which fibrosis was not as advanced. RESULTS: In total, we enrolled 424 biopsy-proven MAFLD patients to the study. In univariate analysis, individuals with greater age, body mass index (BMI), higher aspartate transaminase (AST), MS, impaired fasting glucose, hypertension, enlarged waist circumference (WC), diabetes mellitus (DM), and women had significantly increased risk for fibrosis. In multivariate analysis, it was found that DM, greater age, higher BMI, and increased AST were seen more commonly in MAFLD patients with advanced fibrosis. CONCLUSION: Greater age, a higher BMI, higher AST and a diagnosis of diabetes were more commonly associated with advanced fibrosis. However, DM was found to be the strongest predictive factor of advanced fibrosis in our cohort (OR: 2.495). Multivariate analyses did not indicate a significantly common occurrence of MS in the advanced fibrosis group, despite its important role in MAFLD pathophysiology.

PREDICT identifies precipitating events associated with the clinical course of acutely decompensated cirrhosis.

BACKGROUND & AIMS: Acute decompensation (AD) of cirrhosis may present without acute-on-chronic liver failure (ACLF) (AD-No ACLF), or with ACLF (AD-ACLF), defined by organ failure(s). Herein, we aimed to analyze and characterize the precipitants leading to both of these AD phenotypes. METHODS: The multicenter, prospective, observational PREDICT study (NCT03056612) included 1,273 non-electively hospitalized patients with AD (No ACLF = 1,071; ACLF = 202). Medical history, clinical data and laboratory data were collected at enrolment and during 90-day follow-up, with particular attention given to the following characteristics of precipitants: induction of organ dysfunction or failure, systemic inflammation, chronology, intensity, and relationship to outcome. RESULTS: Among various clinical events, 4 distinct events were precipitants consistently related to AD: proven bacterial infections, severe alcoholic hepatitis, gastrointestinal bleeding with shock and toxic encephalopathy. Among patients with precipitants in the AD-No ACLF cohort and the AD-ACLF cohort (38% and 71%, respectively), almost all (96% and 97%, respectively) showed proven bacterial infection and severe alcoholic hepatitis, either alone or in combination with other events. Survival was similar in patients with proven bacterial infections or severe alcoholic hepatitis in both AD phenotypes. The number of precipitants was associated with significantly increased 90-day mortality and was paralleled by increasing levels of surrogates for systemic inflammation. Importantly, adequate first-line antibiotic treatment of proven bacterial infections was associated with a lower ACLF development rate and lower 90-day mortality. CONCLUSIONS: This study identified precipitants that are significantly associated with a distinct clinical course and prognosis in patients with AD. Specific preventive and therapeutic strategies targeting these events may improve outcomes in patients with decompensated cirrhosis. LAY SUMMARY: Acute decompensation (AD) of cirrhosis is characterized by a rapid deterioration in patient health. Herein, we aimed to analyze the precipitating events that cause AD in patients with cirrhosis. Proven bacterial infections and severe alcoholic hepatitis, either alone or in combination, accounted for almost all (96-97%) cases of AD and acute-on-chronic liver failure. Whilst the type of precipitant was not associated with mortality, the number of precipitant(s) was. This study identified precipitants that are significantly associated with a distinct clinical course and prognosis of patients with AD. Specific preventive and therapeutic strategies targeting these events may improve patient outcomes.

Effect of carbon dioxide versus room air insufflation on post-colonoscopic pain: A prospective, randomized, controlled study.

BACKGROUND/AIMS: Room air (RA) and carbon dioxide (CO2) are widely used to insufflate the colon to examine the mucosa in colonoscopy. Pain, discomfort, and bloating can be seen during and after colonoscopy secondary to bowel distention. This study aimed to investigate the effect of CO2 on post-procedure pain sensation (PPPS) in comparison with RA. MATERIALS AND METHODS: Patients were randomly assigned to the RA and CO2 insufflation groups in a 1:1 ratio. The visual analog scale (VAS) was used to measure the pain before and after the colonoscopy. VAS score of 0 was accepted as the absence of pain and above 0 was accepted as the presence of pain. The primary outcome was to investigate the effect of CO2 insufflation on PPPS. Secondary outcomes were to investigate the other contributing factors affecting PPPS and the effect of CO2 on PPPS in patients with inflammatory bowel disease (IBD). RESULTS: A total of 204 patients were enrolled in the study. No significant difference in PPPS was seen between the 2 groups at any point in time after the colonoscopy. Furthermore, there was no significant difference in pain sensation between the CO2 and RA groups in patients with IBD. When we investigated the other contributing factors to pain sensation, body-mass index (BMI) was found to be significant at 30 minutes and BMI and colonoscopy time were found to be significant at 6 hours afterwards. CONCLUSION: We found no favorable effect of CO2 insufflation on PPPS in colonoscopy, including in patients with IBD.

Validation and reliability of the Turkish version of the inflammatory bowel disease questionnaire for ulcerative colitis and Crohn's disease.

BACKGROUND/AIMS: Inflammatory bowel diseases (IBD) impairs patients' quality of life (QoL). Inflammatory bowel disease questionnaire (IBDQ) is created to measure the health-related QoL specific for IBD. We planned to investigate the validation and reliability of the Turkish translation of IBDQ. MATERIALS AND METHODS: Patients filled self-report questionnaires (Turkish Inflammatory bowel disease questionnaire (TrIBDQ) and Short Form-36 (SF-36)) themselves under a physician's supervision, and they were free to ask questions about the questionnaires. The participants then filled the same questionnaire after at least two weeks. Construct validity, discriminant ability, reliability, and susceptibility to change were analyzed separately for the IBD patients. Intra-class correlation coefficient (ICC) was used to assess test-retest reliability. Cronbach's alpha values were used to assess internal consistency. RESULTS: A hundred patients enrolled in the study, 53 with Crohn's disease (CD), 47 with ulcerative colitis (UC). We found a moderate to high positive correlation between the TrIBDQ domains and the SF-36 dimensions. In UC and CD, TrIBDQ was able to differentiate active disease and remission. We found Cronbach's alpha for TrIBDQ domains ranged from 0.76-0.94 in CD and from 0.79-0.92 in UC. The total Cronbach's alpha for TrIBDQ was 0.96 in CD and 0.95 in UC. Sensitivity-to-change analyses of the bowel, systemic, and emotional scores showed statistically significant differences between their baseline and follow-up values. CONCLUSION: TrIBDQ is a valid and reliable tool for assessing the quality of life in Turkish speaking IBD patients. Thus it can be used in clinical research and practice.

External validation of the Toronto hepatocellular carcinoma risk index in Turkish cirrhotic patients.

OBJECTIVES: Toronto hepatocellular carcinoma risk index is developed to stratify cirrhotic patients according to 10-year hepatocellular carcinoma risk. We aimed to validate the performance of Toronto hepatocellular carcinoma risk index in a large Turkish cohort. MATERIALS AND METHODS: We retrospectively reviewed the database of 1287 cirrhotic patients followed-up in a 10-year period (February 2008 to January 2018). All patients were stratified into three groups based on the Toronto hepatocellular carcinoma risk index score as follows: low-risk, < 120; intermediate risk, 120 to 240; and high risk, > 240. Area under the curve and optimal cutoff value of Toronto hepatocellular carcinoma risk index were obtained from receiver operator curve. To reveal the parameters related with hepatocellular carcinoma development, logistic regression analysis was conducted. The cumulative incidences of hepatocellular carcinoma were calculated using the Kaplan-Meier method, and the curves were compared using the log-rank test. RESULTS: Out of 403 enrolled patients, 57 developed hepatocellular carcinoma. The median Toronto hepatocellular carcinoma risk index value was higher in hepatocellular carcinoma (+) group comparing to hepatocellular carcinoma (-) group [267 (70-366) vs. 224 (36-366), P < 0.001]. Out of 57 detected hepatocellular carcinomas, 45 (78.9%) were high risk, 11 (19.3%) were intermediate risk, and only one (1.8%) was low risk at the entry. The area under the curve of the Toronto hepatocellular carcinoma risk index to predict hepatocellular carcinoma was 0.750 (95% confidence interval, 0.683-0.817, P < 0.001). The optimal cutoff value of Toronto hepatocellular carcinoma risk index was 239.5, giving a sensitivity of 78.9% and specificity of 62.7%. As a result, Toronto hepatocellular carcinoma risk index remained to be the only significant parameter that has an affect on hepatocellular carcinoma development [adjusted-odds ratio: 1.016 (95% confidence interval, 1.007-1.024), P<0.001]. CONCLUSION: The present study validated the performance of Toronto hepatocellular carcinoma risk index in Turkish cirrhotic patients to predict hepatocellular carcinoma risk, which can be considered as a tool for personalized surveillance.

Real-world efficacy and safety of Ledipasvir + Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience.

BACKGROUND/AIMS: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. MATERIAL AND METHODS: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)±ribavirin (RBV) orombitasvir/paritaprevir/ritonavir±dasabuvir (PrOD)±RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. RESULTS: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90±54.60 U/L to 17.00±14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51±4.54 to 7.32±3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0±16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%). CONCLUSION: LDV/SOF or PrOD±RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.
