BACKGROUND Assessment of the gluten-induced small-intestinal mucosal injury remains the cornerstone of celiac disease diagnosis. Usually the injury is evaluated using grouped classifications (e.g. Marsh groups), but this is often too imprecise and ignores minor but significant changes in the mucosa. Consequently, there is a need for validated continuous(More)
Celiac disease (CD) is currently considerably underdiagnosed, setting the need for developing tools to select patients with probability of CD, who warrant further testing. Red blood cell distribution width (RDW) has been shown in previous studies to be a sensitive predictor for CD, but it lacks specificity. Splenic hypotrophy is also noted frequently in(More)
Canonical Wnt/β-catenin signaling regulates the homeostasis of intestinal epithelium by controlling the balance between intestinal stem cell self-renewal and differentiation but epigenetic mechanisms enacting the process are not known. We hypothesized that epigenetic regulator, Polycomb Repressive Complex-2 (PRC2), is involved in Wnt-mediated epithelial(More)
BACKGROUND Coeliac disease (CD), due to its protean clinical manifestation, is still very under diagnosed in adults and delays in diagnosis may take years and even decades. Simple tools to find cases in primary care may help to identify patients for further diagnostic tests. We have evaluated the usefulness of an on site rapid fingertip whole blood(More)
AIM To evaluate whether coeliac disease (CD) can be diagnosed by measuring autoantibodies without small-intestinal mucosal biopsies in children with type 1 diabetes. METHODS Case finding of CD was undertaken in 181 consecutive IgA-competent children with type 1 diabetes using transglutaminase 2 (TG2) and endomysial IgA antibody (EMA) tests in serum and(More)
OBJECTIVES Several recent celiac disease guidelines recommend the acquisition of duodenal bulb biopsies for diagnostics. This is in conflict with previously reported evidence and routine practice from the 1960s onward. We reopened the issue in a prospective multicenter study and used morphometric variables in evaluating the usefulness of bulb biopsies in(More)
BACKGROUND Primary intestinal lymphangiectasia (Waldmann's disease) is a rare disease characterized by dilated lymphatics in the small bowel leading to an exudative enteropathy with lymphopenia, hypoalbuminemia and hypogammaglobulinemia. CASE PRESENTATION We report the case of a 23 year-old male who presented with chronic anemia and in whom primary(More)
Celiac disease (CD) is characterized by an abnormal immune response in susceptible individuals to dietary gluten derived from wheat, rye and barley. The disease affects not only the small bowel mucosa, but also many other extraintestinal organs resulting bone, liver, neurologic, skin and reproductive system disorders. The details of the pathogenic mechanism(More)
