Acute pancreatitis in Turkey: Results of a nationwide multicenter study.

BACKGROUND: Acute pancreatitis (AP) is the most common gastrointestinal disease requiring hospitalization, with significant mortality and morbidity. We aimed to evaluate the clinical characteristics of AP and physicians' compliance with international guidelines during its management. METHODS: All patients with AP who were hospitalized at 17 tertiary centers in Turkey between April and October 2022 were evaluated in a prospective cohort study. Patients with insufficient data, COVID-19 and those aged below 18 years were excluded. The definitions were based on the 2012 revised Atlanta criteria. RESULTS: The study included 2144 patients (median age:58, 52 % female). The most common etiologies were biliary (n = 1438, 67.1 %), idiopathic (n = 259, 12 %), hypertriglyceridemia (n = 128, 6 %) and alcohol (n = 90, 4.2 %). Disease severity was mild in 1567 (73.1 %), moderate in 521 (24.3 %), and severe in 58 (2.6 %) patients. Morphology was necrotizing in 4.7 % of the patients. The overall mortality rate was 1.6 %. PASS and BISAP had the highest accuracy in predicting severe pancreatitis on admission (AUC:0.85 and 0.81, respectively). CT was performed in 61 % of the patients, with the majority (90 %) being within 72 h after admission. Prophylactic NSAIDs were not administered in 44 % of the patients with post-ERCP pancreatitis (n = 86). Antibiotics were administered to 53.7 % of the patients, and 38 % of those received them prophylactically. CONCLUSIONS: This prospective study provides an extensive report on clinical characteristics, management and outcomes of AP in real-world practice. Mortality remains high in severe cases and physicians' adherence to guidelines during management of the disease needs improvement in some aspects.

Evaluation of the effects of the FODMAP diet and probiotics on irritable bowel syndrome (IBS) symptoms, quality of life and depression in women with IBS.

BACKGROUND: The present study aimed to evaluate the effects of fermented oligosaccharide, disaccharide, monosaccharide and polyols (FODMAP) diet therapy and probiotics on irritable bowel syndrome (IBS) symptoms, quality of life and depression in women diagnosed with IBS. METHODS: For the study, 52 female IBS patients between the ages of 20 and 55 were enrolled. Individuals were monitored for 6 weeks in two groups. A low-FODMAP diet was given to the first group and a low-FODMAP diet plus a probiotic supplement was given to the second group (Lactobacillus rhamnosus). Three-day food intake records were kept at the start of the study and continued up to its conclusion, with a weekly check-in in between. At the start and end of the trial, participants completed the Hospital Anxiety and Depression Scale, IBS Quality of Life Scale (IBS-QOL) and IBS Symptom Severity Score (IBS-SSS). The Bristol Stool Scale was also used by the subjects to record their daily stool densities. RESULTS: At the end of the study, it was determined that the daily intake of FODMAP (lactose [g] + oligosaccharides [g] + mannitol [g] + sorbitol [g]) decreased significantly in both groups (p < 0.05). At the end of the study, it was determined that the IBS-SSS, anxiety and depression scores of the individuals in both groups decreased significantly and their IBS-QOL scores increased significantly (p < 0.05). However, the difference between these values between the groups was not statistically significant (p > 0.05). CONCLUSIONS: A low-FODMAP diet has been demonstrated to benefit people by lessening the severity of their IBS symptoms and enhancing their quality of life. No evidence was found, however, to indicate that the FODMAP diet would be more beneficial on these metrics if additional probiotics were used. It should be emphasised that the reaction of probiotic strains may vary depending on the IBS subtype.

Hepatitis B Reactivation in Patients Treated with Direct-Acting Antivirals for Hepatitis C.

INTRODUCTION: There is limited research about HBV reactivation (HBVr) due to direct-acting antivirals (DAA) for HCV and most are limited by short duration of follow-up, small sample size, and absence of baseline HBV DNA. We aimed to determine the incidence and clinical course of HBVr in HBsAg and/or anti-HBcIgG positive patients treated with DAA for HCV. METHODS: Seven centers retrospectively analyzed their database on HCV patients treated with DAA between 2015 and 2019. Patients with HBV coinfection or resolved HBV infection were enrolled. Serum transaminases, HBsAg, HBeAg, and HBV DNA were followed every 4 weeks during DAA treatment and every 12 weeks 1 year after treatment. Entecavir or tenofovir disoproxil fumarate was started in case of HBVr. The development of HBVr, HBV flare, liver failure, and mortality were determined. RESULTS: 852 patients received DAA treatment for HCV. Among them, 35 (4.1%) had HBV coinfection and 246 (28.9%) had resolved HBV infection. 257 patients (53.3% male, mean age: 63 ± 9) constituted the study group (29 with coinfection and 228 with resolved infection). Three patients with coinfection were HBV DNA positive. HBVr developed in 10 (34.5%) HBsAg positive patients, either during (n = 3) or 12-48 weeks after finishing DAA treatment. HBV flare and acute liver failure developed in 1 patient (3.4%), each. Two patients with resolved infection developed HBVr (0.87%) and one (0.44%) had HBV flare. Overall, none of the patients died or underwent liver transplantation due to HBVr. CONCLUSION: Patients with HBV/HCV coinfection have a high risk of HBVr after DAA treatment and should receive antiviral prophylaxis. Patients with resolved infection have a low risk of HBVr and can be monitored by serial ALT measurements.

Prevalence of Pancreatic Steatosis and Its Associated Factors in Turkey: A Nation-Wide Multicenter Study.

BACKGROUND/AIMS:  Pancreatic steatosis (PS) is a pathology associated with metabolic syndrome (MS), endocrin and exocrine disfunctions of the pancreas, and fatty liver. The data on the frequency of PS are very limited. We aimed to evaluate the frequency of PS detected by transabdominal ultrasonography (TAU) in gastroenterology clinics located in different geographical regions of Turkey and the factors associated with it. MATERIALS AND METHODS:  Volunteers were evaluated by TAU for PS and hepatosteatosis (HS), and its degree. Pancreatic stiffness was evaluated by ultrasonographic shear wave elastography (SWE). All demographic, physical, and biochemical parametres were measured. RESULTS:  A total of 1700 volunteers from 14 centers throughout Turkey were included in the study. Mean age was 48.03 ± 20.86 years (56.9% female). Prevalance of PS was detected in 68.9%. In the PS group, age, body mass index (BMI), waist circumference, systolic blood pressure, fasting blood glucose (FBG), lipid levels, insulin resistance, diabetes mellitus, hypertension, MS frequency, and pancreatic SWE score were increasing, and fecal elastase level was decreasing in correlation with the degree of PS. The frequency of HS was 55.5%. Hepatosteatosis [odds ratio (OR): 9.472], increased age (OR: 1.02), and BMI (OR: 1.089) were independent risk factors for the occurrence of PS. Lean-PS rate was 11.8%. The lean-PS group was predominantly female and younger than non-lean PS. Also it has lower blood pressure, FBG, liver enzymes, lipid levels, and HS rates. CONCLUSION:  The frequency of PS was found 68.9% in Turkey. Its relationship was determined with age, BMI, HS, MS (and its components), pancreatic stiffness, and fecal elastase level.

The efficacy and tolerability of glecaprevir/pibrentasvir treatment in a real-world chronic hepatitis C patients cohort.

Background and Aim: The aims of the present study were to evaluate the real-life efficacy and tolerability of glecaprevir (GLE)/pibrentasvir (PIB) in the treatment of patients with chronic hepatitis C (CHC). Materials and Methods: Between May 2019 and May 2022, 686 patients with CHC, treated with GLE/PIB combination from 21 participating centers in Turkiye, were enrolled in the study. Results: All patients were Caucasian, and their median age was 56 years. At the start of GLE/PIB treatment, the median serum Hepatitis C virus RNA and serum alanine amino transaminase (ALT) levels were 6.74 log10 IU/mL and 47 U/L, respectively. Fifty-three percent of the patients were infected with genotype 1b, followed by genotype 3 (17%). Diabetes was the more common concomitant disease. The sustained virological response (SVR12) was 91.4% with intent-to-treat analysis and 98.5% with per protocol analysis. The SVR12 rates were statistically significant differences between the patients who were i.v. drug users and non-user (88.0% vs. 98.8%, p=0.025). From the baseline to SVR12, the serum ALT levels and Model for End-Stage Liver Disease score were significantly improved (p<0.001 and p=0.014, respectively). No severe adverse effect was observed. Conclusion: GLE/PIB is an effective and tolerable treatment in patients with CHC.

Lymphocyte to Monocyte Ratio and C-Reactive Protein Combination as the Best Simple Predictor of Treatment Response in Cirrhotic Patients with Culture Negative Neutrocytic Ascites.

Objectives: The aim of this study was to evaluate the most ideal inflammatory markers for treatment response and to determine a cutoff value that could predict response to treatment for culture negative neutrocytic ascite (CNNA) patients. Methods: This is a retrospective cross-sectional case-controlled study. Patients with CNNA were evaluated by taking ascites fluid sampling at the beginning and on the 5th day of treatment. Neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and neutrophil-to-monocyte ratio were calculated. Results: Of the 123 cases with cirrhotic ascites disease, 59 were CCNA and 64 were the control group without ascite-fluid infection. There were statistically significant differences for blood monocyte count, NLR (p<0.01), LMR, and C-reactive protein (CRP) (p<0.001) between two groups. Patients in the CNNA group were compared before and after treatment among themselves for the treatment response. There was statistically significant difference in mean platelet volume, monocyte, LMR, and CRP (p<0.05) between two groups. After receiver operator characteristics curve analysis, the best cutoff value for monocyte was <0.64 × 103/µL (sensitivity 49.2%, specificity 74.6%, positive predictive value [PPV] 65.9%, and negative predictive value [NPV] 59.5%) (p<0.01), for LMR was ≥1.7 (sensitivity 76.3%, specificity 78%, PPV 77.6%, and NPV 76.7%), and for CRP was ≤18 mg/L (sensitivity 91.5% specificity 57.6%, PPV 68.4%, and NPV 87.2%) (p<0.001). When LMR and CRP were used together, sensitivity (86.5%), specificity (83.1%), PPV (83.6%), and NPV (86%) were found to be statistically significantly higher (p<0.001). Conclusion: Our results showed that in cirrhotic patients with CNNA, combined LMR + CRP can be used as a novel, low cost and non-invasive test to predict treatment response.

Changes in Hepatitis C Awareness in Different Disciplines During COVID-19.

BACKGROUND: We aimed to determine the awareness of referring hepatitis C virus patients to the relevant departments and the effect of the pandemic period on this subject. METHODS: A total of 65 743 patients with anti-hepatitis C virus requests before and during the COVID-19 pandemic were retrospectively screened. Anti-hepatitis C virus-positive patients were divided into 5 groups according to age distribution. The distribution of patients with anti-hepatitis C virus positivity was compared according to age groups, before and during COVID-19. Anti-hepatitis C virus-pos- itive patients who were not requested hepatitis C virus RNA were evaluated individually according to the departments, and hepatitis C virus awareness was compared before and during COVID-19. RESULTS: Anti-hepatitis C virus positivity rate was 1.54% before COVID-19; this rate was 2.15% during COVID-19. When the anti-hep- atitis C virus positivity rate was compared in terms of age distribution according to before and during COVID-19, it was observed that there was a statistically significant decrease in the >65 age group in the COVID-19 period (P = .004). It was found that 216 (32%) of the patients who had anti-hepatitis C virus (+) before COVID-19 and 231 (48.1%) of the patients during COVID-19 were not requested hepatitis C virus RNA test (P < .0001). The departments with the highest awareness of hepatitis C virus were gastroenterology, infec- tious diseases, hematology, gynecology and obstetrics, and oncology, while the departments with the lowest hepatitis C virus awareness were ophthalmology, psychiatry, and general surgery. It was found that chronic hepatitis C virus awareness decreased in all departments during COVID-19. CONCLUSION: Hepatitis C virus awareness has decreased in all medical departments despite the physician alert system during COVID-19 and also the rate of anti-hepatitis C virus (+) patients decreased in the group aged >65 years during the pandemic.

The effect of sarcopenia and serum myokines on prognosis and survival in cirrhotic patients: a multicenter cross-sectional study.

OBJECTIVE: Sarcopenia is one of the most significant contributors to morbidity in patients with chronic liver disease. Serum myokines are potential biomarkers for detecting early sarcopenia. We aimed to investigate the relationship between serum myokines and cirrhosis-related mortality in the early stages of the disease. METHODS: In total, 262 patients and 50 healthy controls were enrolled in this study, which was designed as a multicenter cross-sectional study. At the beginning of the study, sarcopenia was defined by computed tomography scans using the third lumbar vertebra skeletal muscle index. Serum myostatin, irisin, and follistatin levels, nutritional status of the patients, and muscle strength as measured by the handgrip test were recorded. Cirrhosis-related mortality and overall survival were evaluated in the fourth year of the study as the second checkpoint of cross-sectional analysis. RESULTS: A total of 145 (55.3%) patients were diagnosed with sarcopenia. Multivariate analysis revealed that low BMI, high levels of myostatin, and decreased irisin levels were independent predictors of sarcopenia. While serum irisin level was the most predictive parameter in terms of 4th-year cirrhosis-related mortality in the CHILD A group, serum myostatin levels were found more indicative in the CHILD BC group regardless of sarcopenia status ( P < 0.001). CONCLUSION: Serum myostatin levels predict sarcopenia in all stages of cirrhosis. Serum irisin levels can also be used as a potential biomarker to predict both treatable sarcopenia and cirrhosis-related mortality in CHILD A patients.

Characteristics of patients with hepatocellular carcinoma: A multicenter study.

Background and Aim: The aim of the present study was to examine the etiology of hepatocellular carcinoma (HCC) by underlying cause and determine the characteristics and clinical features of patients with HCC. Materials and Methods: The study comprised 1802 HCC patients diagnosed and followed up by Liver Diseases Outpatient Clinics in 14 tertiary centers in Turkey between 2001 and 2020. Results: The mean age was 62.3±10.7 years, and 78% of them were males. Of the patients, 82% had cirrhosis. Hepatitis B virus (HBV) infection was the most common etiology (54%), followed by hepatitis C virus (HCV) infection (19%) and nonalcoholic fatty liver disease (NAFLD) (10%). Of the patients, 56% had a single lesion. Macrovascular invasion and extrahepatic spread were present in 15% and 12% of the patients, respectively. The median serum alpha-fetoprotein level was 25.4 ng/mL. In total, 39% of the patients fulfilled the Milan Criteria. When we compared the characteristics of patients diagnosed before and after January 2016, the proportion of NAFLD-related HCC cases increased after 2016, from 6.6% to 13.4%. Conclusion: Chronic HBV and HCV infections remain the main causes of HCC in Turkey. The importance of NAFLD as a cause of HCC is increasing.

Relationship between Pancreas Exocrine Insufficiency and Cardiac Autonomic Neuropathy in Patients with Type 2 Diabetes Mellitus.

BACKGROUND: The exocrine function of the pancreas is controlled by the autonomic nervous system (ANS), and autonomic neuropathy is a common and serious complication of diabetes. There are many factors contributing to the development of autonomic neuropathy in diabetic patients. Cardiovascular tests have been developed to evaluate the function of the ANS. This study investigated the relationship between cardiovascular autonomic neuropathy (CAN) and pancreas exocrine insufficiency (PEI) in diabetic patients. METHODS: This study evaluated 110 individuals with type 2 diabetes mellitus (T2DM) and 40 healthy volunteers. Autonomous neuropathy tests were utilized to diagnose patients, and Ewing and Clarke's criteria were employed to assess the severity of autonomous dysfunction. Stool samples were also collected from patients to measure fecal elastase-1 (FE-1). RESULTS: A 65.5% incidence of PEI was observed in DM patients. There was no significant correlation among the duration of disease, C-peptide, HbA1c, and PEI, respectively (P = .782, P = .521, P = .580). However, a significant difference between DM patients and controls in terms of cardiac dysautonomia (P = .001) was seen. Moreover, a statistically significant correlation between the degree of cardiac dysautonomia and FE-1 level was observed within the patient group (P =.001). CONCLUSION: It is possible that the disruption of exocrine hormone secretion in the pancreas due to the impairment of enteropancreatic reflexes is secondary to diabetic autonomic neuropathy and resulting in PEI. This study also showed that autonomic neuropathy might develop and cause PEI in diabetic patients without known added confounding factors.

HBV flare associated with immunosuppressive treatments: it is still dangerous in the third-generation antivirals era.

BACKGROUND: There are limited data about the mortality and morbidity of patients with HBV flare related to immunosuppressive treatments (IST) in the third-generation antivirals era. Herein, we performed a multi-centric study in patients treated with entecavir (ETV) or tenofovir disoproxil fumarate (TDF) and evaluated their clinical course. METHODS: The study group included patients who were referred to gastroenterology or infectious disease specialists at eight different hospitals in Turkey. HBV flare was defined as at least a threefold elevation in alanine aminotransferase (ALT) levels above the upper limit of normal range. The demographic data, IST protocol, virological markers, liver tests, international normalized ratio (INR), HBV DNA, reactivation risk profile according to AGA guideline, MELD and MELD-Na scores were retrospectively evaluated. The primary aim of the study was to determine the liver-related mortality, including transplantation, at 12 weeks and factors predicting it. Secondary aims were to compare ETV and TDF with respect to mortality and time to ALT, bilirubin normalization and HBV DNA undetectability. RESULTS: The study group included 40 patients (29 males, mean age: 57 ±12 years). Twenty-five patients (62.5%) had a high risk of reactivation. Twenty-six patients received TDF and 14 patients received ETV treatment. Eight (20%) patients developed acute liver failure and one patient (2.5%) underwent living donor liver transplantation. Seven patients died due to liver-related complications, revealing a mortality rate of 17.5%. In multivariate analysis, total bilirubin levels at the onset, ALT levels and delta-MELD score at the first week were the independent risk factors for liver related mortality (HR: 1.222, 1.003, 1.253 and 95% CI: 1.096, 1.362; 1.001, 1.004 and 1.065, 1.470, respectively). There was no significant difference between the TDF and ETV groups with respect to time to normalize ALT and bilirubin levels, HBV DNA undetectability and mortality rates (16% and 21.4%, respectively). CONCLUSIONS: HBV flare associated with IST has a high mortality in the third-generation antivirals era. High total bilirubin at the onset and high ALT and delta-MELD score at the first week predict poor prognosis.

Does celiac disease cause autoimmune sensorineural hearing loss?

BACKGROUND/AIMS: The primary aim of this study is to identify whether an autoimmune sensorineural hearing loss is an extraintestinal neurological manifestation in adult CD patients. The secondary aim is to identify whether the duration of a gluten-free diet has an effect on the hearing levels of CD patients. MATERIALS AND METHODS: This prospective study consisting of 103 adult CD patients and 79 healthy controls between May 2012 and August 2018 at the University of Gaziantep Gastroenterology and Otorhinolaryngology Departments. CD patients were divided into two groups as remission or active, according to their gluten-free diet duration and serum levels of anti-t-TG. The control group was checked both for CD symptoms and anti-t-TG serum levels. Both participants performed a pure tone audiometry after detailed ear nose and throat examination. RESULTS: Only 4 of 103 CD patients showed sensorineural hearing loss. There was no statistically significant difference between hearing levels of the CD patients and the control group in both measurements of air and bone conductions. The hearing levels comparing the remission and active CD patients did not show any difference in air and bone conduction frequencies. CONCLUSION: In this study with a higher number of CD patients when compared with the previous studies, it has been shown that CD does not appear to cause autoimmune sensorineural hearing loss. In addition, the status of the patients regarding the activeness or the remission of CD did not display a differ between the CD patients in terms of hearing levels.

The safety and efficacy of ERCP in the pediatric population with standard scopes: Does size really matter?

Experience with endoscopic retrograde cholangiopancreatography in the pediatric population is limited. The aim of this study was to evaluate the outcomes of ERCP in the pediatric population performed by adult gastroenterologists with standard duodenoscopes. This study is a structured retrospective review of endoscopic reports, computerized and paper medical records, and radiographic images of patients under the age of 18 who underwent ERCP for any indication at a tertiary referral centre. Data regarding demographic characteristics and medical history of patients, indications, technical success rate, final clinical diagnosis, and complications were analyzed. Forty-eight children with a mean age of 13 years (range 2-17) underwent a total of 65 ERCPs. The indications of ERCP were as follows; suspected choledocholithiasis (55 %), post-liver transplantation anastomotic biliary strictures (21 %), post-surgical bile duct injury (10 %), choledochal cyst (2 %), recurrent or chronic pancreatitis (10 %), and trauma (2 %). The cannulation success rate in the overall procedure was 93.8 %. Therapeutic interventions were performed in 70.7 % of patients. Post ERCP pancreatitis was the most common complication occurring in 9.2 % of patients, and no procedure related mortality occurred. When performed by well-trained adult gastroenterologists, the use of endoscopic retrograde cholangiopancreatography with standard duodenoscopes is safe in pediatric population.

Idiopathic chylous ascites treated with total parenteral nutrition and octreotide. A case report and review of the literature.

Chylous ascites is the accumulation of lipid-rich lymph in the peritoneal cavity. The usual cause in adults is lymphatic obstruction or leakage caused by malignancy. Non-malignant causes include postoperative trauma, cirrhosis, tuberculosis, pancreatitis and filariasis. A variety of treatment options have been proposed for the management of chylous ascites; however, their effectiveness in idiopathic or primary form is unknown. Here we report a case of chylous acid rapidly resolved with the treatment of fasting, total parenteral nutrition and somatostatin analogue.
