The aim of this study was to select the best approach for screening coeliac disease patients among populations with different grades of disease prevalence. The diagnostic performance was assessed of class A and G antigliadin antibodies and class A antiendomysium antibodies in 93 consecutive outpatients with suspected malabsorption, 44 of whom (47%) had coeliac disease according to duodenal hist...

AIMS To highlight the pitfalls in the diagnosis of coeliac disease and to make recommendations for its diagnosis and the management of refractory cases with equivocal histology. METHODS Six patients, referred since 1989 with a diagnosis of coeliac disease based on duodenal biopsy specimens taken at endoscopy, and who failed to respond to a gluten-free diet were studied. All patients were subj...

INTRODUCTION The sensitivity of invasive diagnostic methods for Helicobacter pylori (H. pylori) infection, particularly of urease rapid test, is decreased in cases of gastroduodenal ulcer and upper gastrointestinal bleeding. OBJECTIVES To assess the influence of blood in the stomach or recent bleeding endoscopic signs in the diagnostic sensitivity of urease rapid test among patients with blee...

The prevalence of coeliac disease among patients with autoimmune hypothyroidism has not been studied before in Jordan and other Arab countries. A cross-sectional record-based review was made of all adult autoimmune hypothyroidism patients who attended a referral centre in Jordan, during an 8-month period. Coeliac disease in these patients was diagnosed by the attending physician based on positi...

A 46-year-old woman underwent upper endoscopy for evaluation of anemia, which revealed whitish granules at the duodenal papilla, diagnosed as duodenal follicular lymphoma (DFL) by biopsy. Computed tomography and abdominal ultrasonography revealed that follicular lymphoma was confined to the duodenum. Seven years after the diagnosis, fluorine-18 fluorodeoxyglucose positron emission tomography sc...

BACKGROUND & AIMS Some patients with refractory gastroesophageal reflux disease (GERD) actually have undiagnosed celiac disease. These patients often undergo an esophagogastroduodenoscopy (EGD) to determine the etiology and severity of GERD. Performing routine duodenal biopsy analysis during an EGD could identify patients with celiac disease. We evaluated the cost effectiveness of this approach...

A 70-year-old man was admitted to our institution due to aggravation of blood-sugar level control and because an abdominal CT showed dilatation of the main pancreatic duct. Upper gastrointestinal endoscopy revealed a flat elevated tumor with central ulceration in the second portion of the duodenum. Subsequent duodenoscopy for a more detailed examination showed that the tumor had originated in t...

Endoscopic duodenal biopsy specimens from 100 predominantly adult Caucasian patients under investigation for gastrointestinal symptoms were used to establish reference ranges for lactase, sucrase, and maltase in the duodenum. Duodenal and jejunal disaccharidase values were compared and the association between disaccharidase activity and morphology in the duodenum was examined. Mean lactase acti...

BACKGROUND/AIMS Extrahepatic biliary atresia (EHBA) is the most important cause of neonatal cholestasis. The validity of different diagnostic methods in the diagnosis of EHBA in developed countries has been presented elsewhere, but data from developing countries with low national incomes are scarce. The aim of this study was to investigate the relative accuracy and roles of abdominal ultrasonog...

BACKGROUND Coeliac disease is defined as a state of immune-mediated hyper-responsiveness to dietary gluten from wheat, barley, or rye in genetically predisposed individuals that results in tissue damage. The diagnosis is made by microscopic examination of a small intestinal biopsy, although serological testing for antibodies against tissue transglutaminase and deamidated gliadin peptide can be ...
