Celiac disease: Should we care about microbes?

Celiac disease: Should we care about microbes? Am J Physiol Gastrointest Liver Physiol. 2019 Jun 12;: Authors: Caminero A, Verdu EF Abstract The prevalence of celiac disease has increased in the last decades suggesting a role for environmental factors in addition to gluten. Several cohort studies have shown that different gastrointestinal infections increase CeD risk. However, the mechanisms by which microbes participate in CeD have been remained elusive. Recently, using animal models, both viral and bacterial opportunistic pathogens were shown to induce immune activation relevant for CeD. The hypothesis that viral and or bacterial infections can contribute to immune activation and breakdown of tolerance towards gluten in genetically susceptible individuals, is thus reinforced. Here, we discuss the evidence regarding the role of microbes in promoting CeD, and the specific pathways triggered by microbes that could participate in CeD pathogenesis. Understanding these pathways will allow us to develop optimal microbiota modulating strategies to help prevent CeD. PMID: 31188640 [PubMed - as supplied by publisher]

Authors: Maiuri L, Raia V, Piacentini M, Tosco A, Villella VR, Kroemer G Abstract Cystic Fibrosis (CF) is the most frequent lethal monogenetic disease affecting humans. CF is characterized by mutations in cystic fibrosis transmembrane conductance regulator (CFTR), a chloride channel whose malfunction triggers the activation of transglutaminase-2 (TGM2), as well as the inactivation of the Beclin-1 (BECN1) complex resulting in disabled autophagy. CFTR inhibition, TGM2 activation and BECN1 sequestration engage in an 'infernal trio' that locks the cell in a pro-inflammatory state through anti-homeostatic feedforward lo...

Lymphocytic gastritis (LG) is uncommon and presents histologically with a nonspecific inflammatory pattern. It is most often associated with celiac disease andHelicobacter pylori gastritis and is rarely associated with other conditions including lymphoma. LG is of clinical importance since its recognition should prompt further clinical evaluation for other disorders.

This study retrospectively reviewed 20 consecutive patients who underwent DP-CAR at a single institution.ResultsEleven of 20 patients (55.0%) received NAC. Their first regimens were gemcitabine (GEM) plus nab-PTX (n = 7, 63.6%), GEM plus S-1 (n = 3, 27.3%), and GEM (n = 1, 9.1%). Although two patients converted to a second regimen, none abandoned NAC due to adverse effects or could not undergo a planned procedure for disease progression. There were no significant differences in intraoperative variables, morbidity, including pancreatic fistula and delayed gas tric emptying, and mort...

AbstractPurpose of ReviewCeliac disease (CD) is an autoimmune enteropathy triggered by gluten. The purpose of this review is to examine the major genetic and environmental factors that contribute to CD pathogenesis.Recent FindingsWe reviewed the current state of knowledge on the genetic and environmental components that play a role in CD onset. A genome-wide association study (GWAS) analysis has highlighted several genes other than HLA involved in CD. Recent studies have shown that HLA haplotype influences the microbiome composition in infants and that dysbiosis in the intestinal microflora, in turn, contributes to loss of...
