Immunoregulatory properties of cell-free DNA in plasma of celiac disease patients - A pilot study.
Authors: Brynychova I, Zinkova A, Hoffmanova I, Korabecna M, Dankova P Abstract The elevated plasma cell-free DNA (cfDNA) concentrations were repeatedly reported in association with the process of inflammation. The qualitative and quantitative characteristics of plasma cfDNA in active (newly diagnosed) celiac disease patients (CD) have not yet been studied despite the fact that cfDNA of healthy individuals is able to regulate immune response. We determined the total cfDNA concentration and relative content of telomeric sequences in plasma cfDNA in CD (n = 10) and healthy age- and sex-matched controls ...

Can Osteopathic Medical Students Accurately Measure Abdominal Aortic Dimensions Using Handheld Ultrasonography Devices in the Primary Care Setting?
Conclusion: When properly trained, osteopathic medical students can accurately measure abdominal aortic diameters using a handheld US device. Training more medical students in ultrasonography would offer increased screening opportunities and possibly reduce AAA-related mortality. Further studies are needed to assess the ability of osteopathic medical students to accurately measure AAAs, as no participants in this study met the criteria for AAA.

Diagnosing celiac disease: A critical overview.
Abstract The diagnosis of celiac disease (CD) no longer rests on a malabsorptive state or severe mucosal lesions. For the present, diagnosis will always require the gold-standard of a biopsy, interpreted through its progressive phases (Marsh classification). Marsh classification articulated the immunopathological spectrum of gluten-induced mucosal changes in association with the recognition of innate (Marsh I infiltration) and T cell-based adaptive (Marsh II, and the surface re-organisation typifying Marsh III lesions) responses. Through the Marsh classification the diagnostic goalposts were considerably widened t...

Smoking in pregnancy, cord blood cotinine and risk of celiac disease diagnosis in offspring
AbstractEcological observations suggest an inverse relationship between smoking in pregnancy and celiac disease (CD) in offspring. While individual-level analyses have been inconsistent, they have mostly lacked statistical power or refined assessments of exposure. To examine the association between pregnancy-related smoking and CD in the offspring, as well as its consistency across data sets, we analyzed: (1) The Norwegian Mother and Child Cohort (MoBa) of 94,019 children, followed from birth (2000 –2009) through 2016, with 1035 developing CD; (2) a subsample from MoBa (381 with CD and 529 controls) with biomarkers; ...

Diffuse large B-cell lymphoma of the small intestine in a patient with refractory coeliac disease.
We report a 54-year-old Caucasian man who presented with chronic diarrhoea and weight loss. He was diagnosed with coeliac disease based on positive serology results and duodenal, jejunal, and ileal biopsies that showed villous atrophy. Despite adherence to a gluten-free diet, there was no clinical remission and enteropathy-associated T cell lymphoma was suspected. Repeated endoscopic biopsy showed persistent mucosal disease but no evidence of lymphoma. Several weeks later he presented with a perforated jejunum. Histology of the resected jejunum showed diffuse infiltration of submucosa and muscularis propria by malignant ly...

The Effect of Gluten-free Diet on Cardiovascular Risk Factors in Newly Diagnosed Pediatric Celiac Disease Patients
Objectives: Although gluten-free diet (GFD) is the only proven therapy for celiac disease (CD), its effect on cardiovascular disease (CVD) risk factors is still unclear. Our aim was to determine whether adherence to GFD affects CVD risk factors among newly diagnosed pediatric CD subjects. Methods: We prospectively enrolled pediatric subjects undergoing upper gastrointestinal endoscopy for suspected CD. We collected anthropometric and laboratory parameters related to CVD risk factors at the time of CD diagnosis and 1 year after initiation of a GFD and evaluated changes in CVD risk factors. Paired t tests or Wilcoxon no...

Frequency of HLA celiac disease risk alleles and haplotypes in healthy adults in Tamil Nadu
AbstractCeliac disease (CeD) occurs only in individuals who are able to express human leukocyte antigens (HLA) DQ2 or DQ8, and these are expressed in nearly a third of healthy people in the West. As the disease is very uncommon in Tamil Nadu, we evaluated the possibility that the relevant genes are infrequent in this population. Four hundred healthy adults without any gastrointestinal abnormalities were recruited from Vellore district of Tamil Nadu. Genomic DNA was extracted from venous blood and amplified by PCR using the allele-specific primers for the following alleles—DQA1*0201, 0301, and 0501 and DQB1*02, ...

Gluten Vehicle and Placebo for Non-Celiac Gluten Sensitivity Assessment.
Abstract Non-celiac gluten sensitivity (NCGS) is a syndrome characterized by gastrointestinal and extraintestinal manifestations triggered after gluten ingestion in the absence of celiac disease and wheat allergy. Because of the lack of biomarkers for NCGS diagnosis, the cornerstone for its assessment is a single- or double-blind placebo-controlled (DBPC) gluten challenge. However, there are some non-standardized points in the diagnostic approach proposed by the experts. This complicate comparisons among the results published by different research groups. The gluten vehicle and placebo must be indistinguishable fr...

The autonomic nervous system regulates pancreatic beta-cell proliferation in adult male rats.
out V Abstract The pancreatic beta-cell responds to changes in the nutrient environment to maintain glucose homeostasis by adapting its function and mass. Nutrients can act directly on the beta-cell and also indirectly through the brain via autonomic nerves innervating islets. Despite the importance of the brain-islet axis in insulin secretion, relatively little is known regarding its involvement in beta-cell proliferation. We previously demonstrated that prolonged infusions of nutrients in rats provoke a dramatic increase in beta-cell proliferation in part due to the direct action of nutrients. Here, we addressed...

Gluten challenge induces skin and small bowel relapse in long-term gluten-free diet-treated dermatitis herpetiformis
Dermatitis herpetiformis (DH) is an extra-intestinal manifestation of coeliac disease causing an itchy, blistering rash. Skin IgA deposits are pathognomonic for DH, and the treatment of choice is a life-long gluten-free diet (GFD). Preliminary evidence suggests that there are DH patients who redevelop gluten tolerance after adherence to a GFD treatment. To examine this, we performed a 12-month gluten challenge with skin and small bowel mucosal biopsies in 19 DH patients who had adhered to a GFD for a mean of 23 years.

Genistein antagonizes gliadin-induced CFTR malfunction in models of celiac disease.
Abstract In celiac disease (CD), an intolerance to dietary gluten/gliadin, antigenic gliadin peptides trigger an HLA-DQ2/DQ8-restricted adaptive Th1 immune response. Epithelial stress, induced by other non-antigenic gliadin peptides, is required for gliadin to become fully immunogenic. We found that cystic-fibrosis-transmembrane-conductance-regulator (CFTR) acts as membrane receptor for gliadin-derived peptide P31-43, as it binds to CFTR and impairs its channel function. P31-43-induced CFTR malfunction generates epithelial stress and intestinal inflammation. Maintaining CFTR in an active open conformation by the C...

Contribution of Non-immune Cells to Activation and Modulation of the Intestinal Inflammation
Conclusions As the intestinal mucosa surface constitutes the major surface of the body which is in direct contact with the outer environment, intestinal immune homeostasis must be accurately regulated. The interplay between commensal microbiota, intestinal stromal cells, and the mucosal immune system components should guarantee the intestinal homeostasis to avoid a sustained inflammation that could induce tissue damage. However, several factors can lead to inflammation through homeostasis breakdown. Figure 1 summarizes the main points that have been reviewed here. We have described what it is known so far about the role o...
