CONTEXT Several studies have demonstrated a higher prevalence of celiac disease (CD) among females with Turner syndrome when compared to the general population. Nevertheless, there is no record in literature concerning this investigation among Brazilian patients. OBJECTIVE To assess the prevalence of CD among a group of Brazilian patients with Turner syndrome. METHODS Fifty-six females with...
The analytical performance and cost-effectiveness of the Wampole Toxin A/B EIA, the C. Diff. Quik Chek Complete (CdQCC) (a combined glutamate dehydrogenase antigen/toxin enzyme immunoassay), two RT-PCR assays (Progastro Cd and BD GeneOhm) and a modified two-step algorithm using the CdQCC reflexed to RT-PCR for indeterminate results were compared. The sensitivity of the Wampole Toxin A/B EIA, Cd...
AIMS to determine whether potential correlations between CD117 and PDGFRA might serve as an indication for targeted therapies. MATERIAL AND METHODS immunohistochemical expression of CD117 and PDGFRA was evaluated in 99 paraffin-embedded GISTs in conjunction with KIT and PDGFRA mutational status. RESULTS CD117-positive staining was noted in 93 out of 99 cases. The predominant staining patter...
Abstract Background Fecal calprotectin (FCP) is a highly sensitive biomarker of intestinal inflammation widely used in diagnostics and monitoring inflammatory bowel disease (IBD). However, it cannot be to localize the activity its levels may false negative or positive some cases. The aim this study was evaluate tissue (TCP) pediatric patients with Crohn’s (CD) correlate FCP clinical disease. Me...
A prospective study with two gastric biopsies taken several years apart was carried out in 117 subjects with intestinal metaplasia who are of the Lewis(a-b+) phenotype. They are residents of a rural Andean region in Colombia displaying very high rates of gastric cancer. The anomalous expression of Lewis(a) antigens in the metaplastic epithelium carried a significantly increased risk of colonic ...
Abstract Background Interferon-γ (IFN-γ) is a major driver of excessive immune response, leading to intestinal mucosal damage and contributing the pathogenesis Crohn’s diseases (CD). In contrast inflammatory cells system, IFN-γ-induced cellular responses has not been well documented in epithelium. The epithelium consists multiple cell types patient-derived organoid model may be appropriate eval...
BACKGROUND Patients with type 1 diabetes mellitus (DM1) have an increased risk of celiac disease (CD). Since CD can be seronegative, more sensible tests for detection are needed. In seronegative patients, CD diagnosis may be difficult because of a lack of specificity. Flow cytometry analysis of lymphocyte populations can be useful in this situation. We aimed to study the prevalence of CD in adu...
OBJECTIVE Diagnostic criteria for coeliac disease (CD) from the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) were published in 1990. Since then, the autoantigen in CD, tissue transglutaminase, has been identified; the perception of CD has changed from that of a rather uncommon enteropathy to a common multiorgan disease strongly dependent on the haplotype...
