Several studies have shown that a large number of patients who are fulfilling the criteria for irritable bowel syndrome (IBS) sensitive to gluten. The aim this study was evaluate effect gluten-free diet on gastrointestinal symptoms in with IBS. In double-blind randomized, placebo-controlled trial, 148 IBS Rome III were enrolled between 2011 and 2013. However, only 72 out commenced up six weeks completed study; clinical recorded biweekly using standard visual analogue scale (VAS). second...
Objective We aimed to determine the predictive capacity and diagnostic yield of a 10-fold increase in serum IgA antitissue transglutaminase (tTG) antibody levels for detecting small intestinal injury coeliac disease (CD) adult patients. Design The study comprised three cohorts. Cohort 1: 740 patients assessed specialist CD clinic at UK centre; cohort 2: 532 with low suspicion referred upper GI endoscopy 3: 145 raised tTG titres from multiple international sites. Marsh 3 histology was used as...
Background Ultra-short coeliac disease (USCD) is defined as villous atrophy only present in the duodenal bulb (D1) with concurrent positive serology. We first, multicentre, international study of patients USCD. Methods Patients USCD were identified from 10 tertiary hospitals (6 Europe, 2 Asia, 1 North America and Australasia) compared age-matched sex-matched conventional disease. Findings (n=137, median age 27 years, IQR 21–43 years; 73% female) younger than those (27 vs 38 respectively,...
Breast cancer (BC) is the leading cause of oncological death for women, in both developed and developing countries. In Iran, breast ranks first among cancers diagnosed women. The aim this study was to present burden including incidence, mortality years life lost (YLL) due Iranian women.National incidence data from annual National Cancer Registration reports 2003 2009 national statistics reported by Ministry Health Medical Education 1995 2010, stratified age group, were included analysis....
Abstract Tapeworms of the species complex Echinococcus granulosus sensu lato ( s. l. ) are cause a severe zoonotic disease – cystic echinococcosis, which is listed among most parasitic diseases in humans and prioritized by World Health Organization. A stable taxonomy E. essential to medical veterinary communities for accurate effective communication role different this on human animal health. l . displays high genetic diversity has been divided into genotypes. Despite several decades...
Objectives Counting intraepithelial lymphocytes (IEL) is central to the histological diagnosis of coeliac disease (CD), but no definitive ‘normal’ IEL range has ever been published. In this multicentre study, receiver operating characteristic (ROC) curve analysis was used determine optimal cut-off between normal and CD (Marsh III lesion) duodenal mucosa, based on counts >400 mucosal biopsy specimens. Design The study designed at International Meeting Digestive Pathology, Bucharest 2015....
Background: Histological changes induced by gluten in the duodenal mucosa of patients with non-coeliac sensitivity (NCGS) are poorly defined. Objectives: To evaluate structural and inflammatory features NCGS compared to controls coeliac disease (CeD) milder enteropathy (Marsh I-II). Methods: Well-oriented biopsies 262 control cases normal gastroscopy histologic findings, 261 CeD, 175 from 9 contributing countries were examined. Villus height (VH, μm), crypt depth (CrD, villus-to-crypt ratios...
Abstract Macrophages (MQs) pro-inflammatory phenotype is triggered by gliadin peptides. Akkermansia muciniphila ( A. ) showed to enhance the anti-inflammatory of MQs. This study aimed investigate effects , on stimulated THP-1 derived macrophages. cell line monocytes were differentiated into MQs phorbol 12-myristate 13-acetate (PMA). treated with before and after stimulation (pre- post-treat). CD11b, as a marker macrophage differentiation, CD206 CD80, M1 M2 markers, evaluated flow cytometry...
We investigated the prevalence of intestinal protozoan parasites in patients with gastrointestinal complaints medical centers Zahedan, Iran. A total 1562 stool samples was examined from July 2004 to January 2006 using microscopy (direct smear, formalin-ether concentration), xenic culture and PCR techniques. Four hundred twenty-seven (27.3%) were infected one or more parasites. Giardia lamblia (10.1%), Entamoeba coli (10%), E. hartmanni (1.7%), Blastocystis hominis (2.2%), Chilomastix mesnili...
AIM:To assess the distribution of human leukocyte antigen (HLA)-DQ2 and -DQ8 in Iranian celiac disease (CD) patients compare them to healthy controls. METHODS:To predict HLA-DQA1 -DQB1 genes, we used six previously reported HLA-tagging single nucleotide polymorphism determine HLA genotypes 59 with 'biopsy-confirmed' CD 151 individuals.To test transferability method, 50 cases controls were also typed using a commercial kit that identifies individual carriers DQ2, DQ7 DQ8 alleles. RESULTS:In...
Hepatitis A virus (HAV) and hepatitis E (HEV) are enteric hepatotropic viruses their prevalence is related to the sanitary conditions of region under investigation. There only a few studies on seroepidemiology these two in general Iranian population. The purpose this investigation was measure infections Between 2006 2007, cross sectional study performed Tehran, Iran. Blood specimens were collected questionnaires filled for 551 persons. Patient sera tested by ELISA anti-HEV anti-HAV IgGs....
