Cím:Frequencies of Genetic Polymorphisms of TLR4 and CD14 and of HLA-DQ Genotypes in Children With Celiac Disease, Type 1 Diabetes Mellitus, or Both / Dezsőfi, A., Szebeni, B., Hermann, CS., Kapitány, A., Veres, G., Sipka, S., Körner, A., Madácsy, L., Korponay-Szabó, I., Rajczy, K., Arató, A.

Megjegyzések:OBJECTIVES: Besides the central role of the adaptive immune system, a disturbance of innate immunity is also involved in the pathogenesis of celiac disease (CD). Inasmuch as CD and type 1 diabetes mellitus (T1DM) frequently coexist because of a common genetic predisposition, our aim was to study the frequency of CD14 C-260T and TLR4 A+896G single nucleotide polymorphisms (SNPs) and the distribution of HLA-DQ genotypes in children affected by CD, T1DM, or both. PATIENTS AND METHODS: TLR4 and CD14 SNPs were tested by polymerase chain reaction, followed by restriction fragment length polymorphism analysis in 80 children with T1DM, 100 children with CD, and 47 children with both CD and T1DM. Determination of HLA-DQ alleles was done by sequence-specific polymerase chain reaction. Frequencies were compared with those of healthy control children. RESULTS: The prevalence of the homozygous CD14 C-260TT genotype was significantly (P = 0.0081) lower in children with T1DM but not in those with CD and T1DM, compared with control children. No difference was found in the genotype and allele frequencies of TLR4 between the studied groups. In patients with T1DM, the frequency of the homozygous HLA-DQ8 genotype was significantly higher than in CD, whereas the frequency of homozygous or heterozygous HLA-DQ2 genotypes did not differ from that in control children. In patients with CD, both homozygous and heterozygous HLA-DQ2 genotypes were significantly more frequent than in the control and T1DM groups, and no elevation in the frequency of the HLA-DQ8 genotypes was observed. In patients with T1DM and those with CD and T1DM, the occurrence of HLA-DQ2/8 heterozygosity was significantly higher than in children with CD only and in control children. CONCLUSIONS: Our results suggest that in patients with T1DM, the CD14 C-260TT homozygous genotype increases the risk for the development of CD. The distribution of HLA-DQ genotype is different in children with CD and T1DM than in children with CD or T1DM only. Determination of the HLA-DQ genotype in children with T1DM may help in estimating the risk for the development of CD.

Megjegyzések:OBJECTIVE: The aim of this study was to summarise the evidence from 2004 toSeptember 2009 on the performance of laboratory-based serological and point ofcare (POC) tests for diagnosing coeliac disease (CD) in children using histology as reference standard.PATIENTS AND METHODS: We searched MEDLINE and EMBASE for studies reporting onchildren for tests based on IgA and IgG anti-gliadin (AGA), endomysial (EmA),anti-transglutaminase-2 (TG2), and anti-deamidated gliadin peptides (DGP)antibodies or POC tests. For inclusion, histological analysis of duodenalbiopsies and sensitivity and specificity for index tests had to be reported. Datawere pooled and summary measures calculated for sensitivity, specificity,positive and negative likelihood ratios ("LR+", "LR-"), and diagnostic oddsratios (DOR). In case of elevated statistical heterogeneity, studies reaching 90%sensitivity or specificity were reported.RESULTS: A total of 2510 articles were reviewed; 16 entered meta-analysis,reporting on 3110 patients (1876 with CD, 1234 without CD). For IgA-EmA,sensitivity was ?90% in 7/11 studies and pooled specificity 98.2%. ForIgA-anti-TG2, 11/15 studies yielded sensitivities ?90% and 13/15 specificities?90%. For IgA-DGP, sensitivity ranged between 80.7% and 95.1% (specificity86.3%-93.1%); for IgG-DGP between 80.1% and 98.6% (specificity 86.0-96.9%).IgA-EmA had the highest pooled DOR (554) and LR+ (31.8) for a laboratory test,followed by IgA-anti-TG2, IgG-DGP, IgA-DGP and IgA-AGA. POC tests showed a pooledsensitivity of 96.4% for IgA-TG2 (specificity 97.7%).CONCLUSIONS: IgA-EmA and IgA-anti-TG2 tests appear highly accurate to diagnoseCD. IgG-anti-DGP tests may help in excluding CD. IgA-AGA and IgA-DGP tests showinferior accuracy. POC tests may achieve high accuracy in the hands ofexperienced readers, but IgA-anti-TG2/EmA were superior.

Megjegyzések: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 haplotypes human leukocyte antigen (HLA)-DQ2 and HLA-DQ8; and CD-specific antibody tests have improved.METHODS:A panel of 17 experts defined CD and developed new diagnostic criteria based on the Delphi process. Two groups of patients were defined with different diagnostic approaches to diagnose CD: children with symptoms suggestive of CD (group 1) and asymptomatic children at increased risk for CD (group 2). The 2004 National Institutes of Health/Agency for Healthcare Research and Quality report and a systematic literature search on antibody tests for CD in paediatric patients covering the years 2004 to 2009 was the basis for the evidence-based recommendations on CD-specific antibody testing.RESULTS:In group 1, the diagnosis of CD is based on symptoms, positive serology, and histology that is consistent with CD. If immunoglobulin A anti-tissue transglutaminase type 2 antibody titers are high (>10 times the upper limit of normal), then the option is to diagnose CD without duodenal biopsies by applying a strict protocol with further laboratory tests. In group 2, the diagnosis of CD is based on positive serology and histology. HLA-DQ2 and HLA-DQ8 testing is valuable because CD is unlikely if both haplotypes are negative.CONCLUSIONS:The aim of the new guidelines was to achieve a high diagnostic accuracy and to reduce the burden for patients and their families. The performance of these guidelines in clinical practice should be evaluated prospectively.

Cím:Autoantibodies and CD : past and future of celiac antibody testing / Ilma R. Korponay-Szabó
Dátum:2014
ISSN:0277-2116
Megjegyzések:Celiac disease (CD) is triggered by the consumption of gluten-containing cereals to which patients mount a T-lymphocyte and antibody response in both immunoglobulin A and immunoglobulin G classes coupled with autoantibody production against self-proteins, predominantly type-2 (tissue) transglutaminase (TG2). TG2 autoantibodies are biologically active and bind to their target protein in the patients' tissues, including the gut and extraintestinal tissues. This peculiar systemic anti-TG2 reaction is dependent on the presence of dietary gluten and stops after its elimination. As both anti-TG2 and anti-gliadin antibodies are activity markers, their detection is valuable for the disease recognition and therapy monitoring. High concentrations of serum anti-TG2 antibody positivity supported by highly specific positivity for endomysial antibodies became the critical component of celiac JPGN Volume 59, Supplement 1, July 2014 Celiac Disease: Past, Present, Future Challenges www.jpgn.org S11

Megjegyzések:BACKGROUND:Endomysial antibodies have recently been shown to react with tissue transglutaminase. This study was undertaken to investigate whether the tissue distribution of transglutaminase is also compatible with reticulin, jejunal, and fibroblast autoantibody binding patterns.METHODS:Sera from patients with and without celiac disease, monoclonal tissue transglutaminase antibodies, and sera from mice parenterally immunized against commercially available tissue transglutaminase, transglutaminase complexed with gliadin, or gliadin were used in indirect immunofluorescence and double-staining studies using both rodent and primate tissues as substrates. Also, antibody competition, affinity chromatography, and potassium thiocyanate extraction studies were undertaken.RESULTS:Tissue transglutaminase antibody binding patterns were identical with the extracellular binding patterns seen with celiac patient sera. Human umbilical cord-derived fibroblasts exhibited both cytoplasmic and extracellular matrix staining. Double staining with patients' sera and tissue transglutaminase antibodies showed complete overlapping. Tissue transglutaminase effectively absorbed reticulin-endomysial antibodies from celiac sera, and patients' sera blocked the staining of the monoclonal tissue transglutaminase antibodies. Potassium thiocyanate extraction abolished the staining patterns, but they were elicited again after readdition of tissue transglutaminase.CONCLUSIONS:Reticulin, endomysial, and jejunal antibodies detect transglutaminase in both rodent and primate tissues, indicating that these tissue autoantibodies are identical

Cím:Prospective significance of antiendomysium antibody positivity in subsequently verified celiac disease / Korponay-Szabó I. R., B. Kovács J., Lörincz M., Gorácz G., Szabados K., Balogh M.
Dátum:1997
Megjegyzések:BACKGROUND: In order to assess their long-term predictability for the diagnosisof celiac disease, antiendomysium antibody results were compared with the outcomeof the Interlaken diagnostic process. METHODS: Prospective gluten challenge was performed in 153 children withpreviously diagnosed flat small-intestine mucosa. In 90 patients (Group A),endomysium antibodies were initially positive, in seven (Group B) they werenegative, and 56 patients (Group C) had no initial serological results. InIgA-deficient persons, IgG antibodies were also assayed, both by theimmunofluorescent method. RESULTS: Histological relapse rates were 100% (90/90), 14.3% (1/7), and 76.8%(43/56), p < 0.001, in Groups A, B, and C, respectively. Each patient withrelapse also exhibited endomysium antibody positivity during the challenge.Patients in whom celiac disease could be finally ruled out remained consistently endomysium-antibody negative. The celiac disease patient in Group B had severesecondary immunoglobulin deficiency at entry, which explained the initialnegativity. Diagnosis based on antiendomysium antibody positivity and flat mucosagave a higher applicability (92.8 vs. 50.3%) and reliability (relapse rate 100vs. 89.6%) than the 1990 European Society of Paediatric Gastroenterology andNutrition (ESPGAN) criteria among these patients. CONCLUSIONS: Endomysium antibody positivity at presentation has been found to be as useful as gluten challenge in the diagnosis of celiac disease, even inpatients under the age of 2 years. Challenge is still advisable in patients with a flat small intestinal mucosa when antiendomysium antibody results are negative or have not been done, as among these patients significantly lower relapse rates were found.
