Efficacy of abatacept treatment in a patient with enteropathy carrying a variant of unsignificance in gene: A case report.

Background: Cytotoxic T Lymphocyte Antigen-4 (CTLA4) deficiency is a genetic defect that causes a common variable immunodeficiency (CVID) clinical phenotype. Several studies have reported an association between CTLA mutations or variants and various autoimmune diseases. Targeted therapy models, which have become increasingly popular in recent years, have been successful in treating CTLA4 deficiency.

Relationship between Helicobacter pylori infection and white matter lesions in patients with migraine.

Can a 1-day clear liquid diet with a split -dose polyethylene glycol overcome conventional practice patterns during the preparation for screening colonoscopy?

Background/aims: A successful screening colonoscopy is closely linked to the quality of a bowel preparation. In this study, we aimed to determine the impact of a 1-day clear liquid diet (CLD) compared to a 3-day combined diet (CMD) accompanied by a split-dose regimen of polyethylene glycol and electrolyte lavage solution (PEG-ELS) for screening colonoscopy.

Materials And Methods: This was a prospective, randomized, endoscopist-blinded study.

Background/aims: The duration of Helicobacter pylori (H. pylori) eradication therapy as a range (e.g.

When abdominal pain knocks the door: an unusual presentation of chronic lymphocytic leukemia.

A 67-year-old man presented non-specific abdominal pain. Polypoid mass at appendiceal orifice in the cecum was found on endoscopic investigation without appendicitis sign. Histopathology elucidated underlying mucosal infiltration that was chronic lymphocytic leukemia.

Effect of Propranolol Treatment on the Incidence of Hepatocellular Carcinoma in Patients Waiting for Liver Transplant With Cirrhosis: A Retrospective, Surveillance Study in a Tertiary Center.

Objectives: Hepatocellular carcinoma is the most frequent primary malignant tumor of the liver and the third most common cause of all cancer-related mortalities. There is a need to develop new strategies to prevent hepatocellular carcinoma, as the incidence of this cancer continues to increase despite all advancements. In this study, our aim was to determine the effects of propranolol treatment on the incidence of hepatocellular carcinoma in cirrhotic patients waiting for liver transplant.

Successful Treatment With Direct-Acting Antiviral Agents of Hepatitis C in Patients With End-Stage Renal Disease and Kidney Transplant Recipients.

Objectives: The introduction of direct-acting antiviral agents has allowed significant chances for treatment for difficult-to-treat populations. This study aimed to investigate the efficacy, tolerability, and safety of these therapies in both patients with end-stage renal disease and kidney transplant recipients with chronic hepatitis C virus infection.

Materials And Methods: This study was a retrospective analysis with prospective follow-up of patients.

Endoscopic Management of the Difficult Bile Duct Stones: A Single Tertiary Center Experience.

. Most common bile duct (CBD) stones can be removed with standard techniques using endoscopic retrograde cholangiopancreatography (ERCP), but in some cases additional methods are needed. In this study we aimed to investigate the management of patients with difficult stones and the factors that affect the outcome of patients that have undergone periodic endobiliary stenting.

Management of suspected common bile duct stone: diagnostic yield of current guidelines.

Background: The American Society for Gastrointestinal Endoscopy (ASGE) has recently published a guideline for suspected CBDS with the intention of reducing unnecessary ERCP and thereby complications. The aim of this study was to assess the diagnostic efficacy of the ASGE guideline.

Methods: Data of patients who underwent ERCP with suspected CBDS were analyzed retrospectively.

The role of soluble tumor necrosis factor like weak inducer of apoptosis and interleukin-17A in the etiopathogenesis of celiac disease: A cross-sectional study.

Our aim in this study was to determine soluble tumor necrosis factor (TNF)-like weak inducer of apoptosis (sTWEAK) and interleukin-17A (IL-17A) levels in celiac disease, and their association with the gluten diet and autoantibodies. Eighty patients with celiac diagnosis and 80 healthy control individuals with similar age, gender and body mass index to the patient group were included in the study. Serum sTWEAK and IL-17A levels were measured by the serum enzyme-linked immunosorbent assay kit.

Double balloon enteroscopy: A 7-year experience at a tertiary care Centre.

Background: Double Balloon Enteroscopy (DBE) provides the opportunity not only to investigate but also apply endoscopic therapeutic interventions for small intestinal disturbances. The aim of this study is to assess the indications, diagnosis, therapeutic interventions, complications and safety in clinical practise of DBE procedures that have been performed in our clinic.

Material-methods: The data of patients who had undergone DBE procedure in our clinic between October 2007 and December 2014 were retrospectively investigated.

Is Gastric Xanthelasma an Alarming Endoscopic Marker for Advanced Atrophic Gastritis and Intestinal Metaplasia?

Background/aim: The clinical significance of gastric xanthelasmas is unknown. We conducted a case-control study in order to evaluate whether gastric xanthelasma is an indicator of advanced atrophic gastritis and intestinal metaplasia.

Material And Method: The study was conducted among 1400 patients who underwent elective upper endoscopy.

Cirrhosis with ascites: Is the presence of hemorrhagic ascites an indicator of poor prognosis?

Background/aims: Hemorrhagic ascites in patients with cirrhosis is described as a RBC (Red Blood cell) > 50,000/mm³ and leads to increased morbidity and mortality. Positive red blood cells at a level of less than 50,000/mm³ (10,000-50,000) may be encountered in the ascites but it is not known whether this is clinically significant or not. This study aimed to examine the outcome of hemorrhagic ascites in patients with advanced cirrhosis.

The Prevalence of Barrett Esophagus Diagnosed in the Second Endoscopy: A Retrospective, Observational Study at a Tertiary Center.

At present, we do not know the exact prevalence of Barrett esophagus (BE) developing later in patients without BE in their first endoscopic screening. The purpose of this study was to determine the prevalence of BE on the second endoscopic examination of patients who had no BE in their first endoscopic examination.The data of the patients older than 18 years who had undergone upper gastrointestinal system endoscopy more than once at the endoscopy unit of our clinic during the last 6 years were retrospectively analyzed.

The predictive value of noninvasive serum markers of liver fibrosis in patients with chronic hepatitis C.

Background/aims: This study aims to show the predictive value of noninvasive serum markers on the hepatic fibrosis level.

Materials And Methods: This cross sectional study involves 120 patients with chronic hepatitis C. The noninvasive markers used were as follows: age-platelet index (AP index), cirrhosis discriminant score (CDS), aspartate aminotransferase (AST)-alanine aminotransferase (ALT) ratio (AAR), fibrosis-4 (FIB-4) index, AST-platelet ratio index (APRI), Goteborg University Cirrhosis Index (GUCI), FibroQ, King's score, platelet count.

Can Serum ST2 Levels Be Used as a Marker of Fibrosis in Chronic Hepatitis B Infection?

Interleukin 33 (IL-33) is a cytokine belonging to the IL-1 superfamily. Soluble ST2 (sST2) binds to IL-33 and by functioning as trap receptor inhibits signal sending to Th2 via transmembrane ST2. Because Th2-type cytokines play an important role in fibrosis, the aim of this study is to determine whether sST2 can be used as a marker of fibrosis in chronic hepatitis B (CHB) patients or not.
