Background: In coeliac disease (CD) patients, the dominant DQ2-A-I-gliadin peptide recognised by CD4 T cells is contained within peptide sequence 57–73 (p57-73) of A-gliadin. This peptide sequence is also located within a 33-mer protease resistant gliadin fragment and therefore is likely to play an important role in the pathogenesis of CD. Aims: Our aim was to determine whether a B cell epitope...

BACKGROUND The detection of anti-transglutaminase IgA (tTG) and anti-endomysial (EMA) is used for screening of celiac disease (CD) with a sensitivity and specificity of 90 and 99% respectively. There is an association between CD and connective tissue diseases (CTD). AIM To report the frequency of IgA tTG and EMA in patients with a definite diagnosis of CTD and inflammatory arthropathies (IA)....

BACKGROUND With the appreciation of the high prevalence of coeliac disease there is increasing use of serology in screening asymptomatic people and testing those with suggestive features. AIM To compare the sensitivities and specificities of the endomysial antibody and the tissue transglutaminase antibody tests. METHODS Using electronic databases a search was made for relevant papers using ...

This study was carried out to characterize the antibody class response by ELISA to seven Klebsiella pneumoniae serotypes (K2, K3, K17, K21, K26, K36, K50) in five different groups, 40 HLA-B27-positive ankylosing spondylitis (AS) patients, 46 patients with Crohn's disease (CD), 38 patients with ulcerative colitis (UC), 50 patients with active anti-endomysial antibody-positive coeliac disease and...

background: vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches. the exact etiology and pathogenesis of vitiligo is not clear. many theories have been presented regarding this subject among them aautoimmune theory is the most important one. the association of vitiligo with other autoimmune disorders has been reported, but the relationship ...

BACKGROUND IgA deficiency causes false-negative IgA-based celiac serology results in patients with celiac disease. Using a case-finding strategy, we examined the prevalence of IgA deficiency, physician evaluation, and management of IgA deficiency during serological testing for celiac disease. METHODS We reviewed consecutive IgA-endomysial antibody (EMA) and serum IgA results from the laborato...

OBJECTIVE To investigate the extent to which the detection of antibodies to gliadin, endomysium, and jejunum predicts the eventual diagnosis of coeliac disease according to the revised ESPGAN diagnostic criteria in a group of patients in whom there is a high suspicion of coeliac disease. DESIGN Clinical assessment and laboratory analysis of patients with suspected coeliac disease. SETTING G...

background: coeliac disease is triggered by ingestion of gluten-containing cereals in genetically susceptible subjects. the aim of the study was to analyze correlation between serum antiendomysial antibody and antiglidin antibody and the grade of pathology in small intestine mucosa in children with celiac disease. materials and methods: this cross-sectional analysis was carried out in a group o...

BACKGROUND AND OBJECTIVE Serological screening enables us to detect patients of celiac disease (CD) before they develop serious complications. This study was planned to assess the prevalence of CD in the family members of index cases by serological screening. PATIENTS AND METHODS A prospective study was conducted on 50 children diagnosed to be having CD. Serological screening of the family me...

OBJECTIVE To report a patient with coeliac disease (CD) associated with primary biliary cirrhosis (PBC) who presented with myopathy without classical symptoms of CD. CLINICAL PRESENTATION AND INTERVENTION A 42-year-old woman presented with inability to walk and marked loss of motor function. She had elevated liver enzymes with a cholestatic pattern. Antimitochondrial antibody M2 band, anti-en...
