BACKGROUND & AIMS: An increase in CD3+TCRγδ+ and a decrease in CD3- intraepithelial lymphocytes (IEL) is a characteristic flow cytometric pattern of celiac disease (CD) with atrophy. The aim was to evaluate the usefulness of both CD IEL cytometric pattern and anti-TG2 IgA subepithelial deposit analysis (CD IF pattern) for diagnosing lymphocytic enteritis due to CD. METHODS: Two-hundred and five patients (144 females) who underwent duodenal biopsy for clinical suspicion of CD and positive celiac genetics were prospectively included...

INTRODUCTION: The diagnosis of celiac disease (CD) is based on histology in combination with anti-tissue transglutaminase (a-tTG) and anti-endomysial antibodies (EMAs). The increase of intraepithelial lymphocytes defines the Marsh 1 histology that appears not to be specific for CD. AIM: To explore the positive predictive value (PPV) and clinical relevance of Marsh 1 histology in suspected CD. METHODS: We carried out an observational prospective study including all consecutive subjects with a Marsh 1 histology...

Interrelationships between parameters of humoral immunity with AB0 blood groups have been investigated. The highest content of IgA to transglutaminase was found in A(II) patients, while the lowest content was found in AB(IV) patients. The blood content on anti-gliadin IgA was higher in healthy donors. The oral liquid of periodontic patients contained anti-gliadin IgA and IgB lacking in healthy donors. It have been found that 47% of healthy people and 52.7% of patients are infcted with Helicobacter pylori. In the group of periodontic patients A(II) individually predominated; they were characterized by the presence of antibodies to H...

Iron deficiency anemia (IDA) is frequent in childhood. Inadequate nutrition and gastrointestinal malabsorption are the frequent causes of IDA in children. But reduced iron absorption and insidious blood loss from the gastrointestinal tract has been identified as the most frequent causes of IDA in older children and adolescents. Therefore the authors evaluated the frequency and etiologies of the upper gastrointestinal system pathologies causing IDA in older pediatric population. Patients with known hematological or chronic diseases, heavy menstrual flow, and obvious blood loss were excluded from the study...

BACKGROUND: Celiac disease has been reported to be associated with gastric abnormalities. The aim of this study was to assess the relationship between the prevalence of celiac disease and Helicobacter pylori infection in an Iranian population of 250 patients. METHODS: Biopsies were taken from the gastric antrum and duodenum. Morphology and histology were evaluated using the updated Sydney system and modified Marsh criteria, respectively. To simplify the interpretation of gastric lesions we classified gastritis in macroscopic and microscopic stages...

Despite elegant regulatory mechanisms, iron deficiency anemia (IDA) remains one of the most common nutritional deficiencies of mankind. Iron deficiency is the result of an interplay between increased host requirements, limited external supply, and increased blood loss. When related to increased physiologic needs associated with normal development, iron deficiency is designated physiologic or nutritional. By contrast, pathological iron deficiency, with the exception of gross menorrhagia, is most often the result of gastrointestinal disease associated with abnormal blood loss or malabsorption...

The aim of this study was to reevaluate the role of infection in inflammatory bowel disease (IBD). Sera from 119 patients with IBD [80 with Crohn's disease (CD); 39 with ulcerative colitis] and 98 healthy controls were assessed using the Bio-Rad BioPlex 2200 for the presence of Toxoplasma gondii, cytomegalovirus, Epstein-Barr virus, Treponema pallidum, and Saccharomyces cerevisiae. Hepatitis B virus, hepatitis C virus (HCV), and anti-Helicobacter pylori antibodies were assessed by ELISA. In addition, sera were tested for a panel of antibodies associated with thrombophilia as well as various autoantibodies...

Type 1 diabetes mellitus (T1DM) is an autoimmune disease with complex interactions between genetic and environmental factors. We compared antibody levels to various infectious agents and of autoimmune-associated autoantibodies between Colombian T1DM patients, their close family members and healthy controls. Significantly lower levels of antibodies against several infectious agents were detected in the T1DM patients. These included Helicobacter pylori (P = 0.01), cytomegalovirus (P = 0.001), Epstein-Barr virus (P = 0...

BACKGROUND: Antibody serology is an important tool in the investigation of celiac disease (CD), but does not always correlate with mucosal appearance in the small intestine. Patients with positive CD serology but normal mucosa (Marsh 0) are at increased risk of future CD. In this study we describe a model for identifying and characterizing individuals with normal mucosa but positive CD serology. Such individuals are sometimes referred to as having latent CD. METHODS: The records of ten Swedish pathology departments were used to identify individuals with biopsies indicating normal duodenal/jejunal mucosa...

BACKGROUND: An increased number of intraepithelial lymphocytes (IELs) can be the only histological feature in early stages of celiac disease (CD). This is also presented in duodenum of patients with Helicobacter pylori-associated gastritis and in autoimmune diseases. Because CD is frequently associated with type 1 diabetes mellitus, we analyzed the density of IELs in the distal duodenum of non-celiac diabetic patients associated or not with H.pylori infection. METHODS: IEL density and the presence of H...

Chronic immune stimulation such as Helicobacter pylori (hp) infection, Sjögren's syndrome or coeliac disease may initiate non-Hodgkin lymphoma (NHL). The opposite (appearance of autoimmunity) has also been reported. The aim of this study was to describe the pattern of these immune markers in patients with lymphoid malignancies. Sera from 96 patients with NHL (median age 72, range 38-88, F/M 41/55) were analysed with ELISA to determine the frequency of antibodies against guinea pig (gp) and human recombinant (hr) transglutaminase type 2 (Tg2), and hr factor XIII subunit a* (part of the Tg-family), extractable nuclear antigen (ENA), and hp...
