    <ns1:description language="sr">Uvod:Celijačna bolest (CB), je autoimuna bolest izazvana glutenom. U pedijatrijskojgastroenterologiji, dijagnoza CB može se postaviti, samo serološki, bez biopsijesluzokože tankog creva, ako je zadovoljen kriterijum da su antitela na tkivnutransglutaminazu 10 puta veća u odnosu na gornju vrednost normalnih vrednosti uzpotvrdan test potvrdan test sa antiendomizijumskim antitelima. HLA-DQ2/DQ8tipizacija se radi mandatorno u određenim situacijama.Cilj studije:Procena primenljivost koncentracije serumskih antitela na tkivnu transglutaminazu(TTG) IgA i IgG i HLA-DQ2/DQ8 tipizacije kao alternative duodenalnoj biopsiji udijagnostikovanju CB u dece.Metod: Studija obuhvatila je ukupno 179 pedijatrijskih pacijenata uzrasta od 1 do 18godina. Kod svih pacijenata izvršeno je određivanje TTG IgA i TTG IgG antitela, kaoi tipizacija humanog leukocitnog antigena (HLA) DQ2/DQ8. Histologija duodenalnihbiopsija interpretirana je prema modifikovanom Marš opisu.Rezultati:Dijagnoza CD je potvrđena kod 101 (56%) pacijenta u ispitivanoj populaciji. Kodslučajeva CD, HLA-DQ2/DQ8 bio je pozitivan kod 100 pacijenata (99%). Antitela TTGIgA u koncentraciji većoj od 100 U/ml otkrivena su kod 77 (76,2%) pacijenata sa CD,dok je značajno manji broj imao povišena TTG IgG antitela 29 (28,7%) (p &lt; 0,001).Utvrđena je statistički visoko značajna povezanost duodenalnih lezija Marš stepena3 sa koncentracijom TTG IgA 10 puta višom od gornje granice normale (ULN) (p &lt;0,001).Zaključak:Koncentracija TTG IgA 10 puta veća od ULN značajno je pozitivno povezana sahistopatološkim nalazima Marš stepena 3. Određivanje specifičnih antitela ukombinaciji sa HLA-DQ2/DQ8 tipizacijom pokazuje se kao dovoljno za postavljanjedijagnoze CD, podržavajući činjenicu da se duodenalna biopsija može izbeći kodznačajne većine pacijenata 77%</ns1:description>
    <ns1:description language="en">Introduction:Celiac disease (CD) is an autoimmune disorder triggered by gluten. In pediatricgastroenterology, the diagnosis of CD can be established serologically, without a duodenalmucosal biopsy, if the criterion is met that anti-tissue transglutaminase (TTG) antibodies areelevated to more than 10 times the upper limit of normal (ULN), with a positive confirmatorytest for anti-endomysial antibodies. HLA-DQ2/DQ8 typing is mandatory in certain situations.Aim of the study:To evaluate the applicability of serum anti-tissue transglutaminase (TTG) IgA and IgGconcentrations and HLA-DQ2/DQ8 typing as an alternative to duodenal biopsy in diagnosingCD in children.Methods:The study included a total of 179 pediatric patients aged 1 to 18 years. All patients underwentmeasurement of TTG IgA and tTG IgG antibodies, as well as human leukocyte antigen (HLA)DQ2/DQ8 typing. Duodenal biopsy histology was interpreted according to the modified Marshclassification.Results:The diagnosis of CD was confirmed in 101 (56%) patients in the study population. Among CDcases, HLA-DQ2/DQ8 was positive in 100 patients (99%). TTG IgA antibodies atconcentrations &gt;100 U/ml were detected in 77 (76.2%) CD patients, while a significantlysmaller number had elevated TTG IgG antibodies—29 (28.7%) (p &lt; 0.001). A statisticallyhighly significant association was found between Marsh grade 3 duodenal lesions and TTG IgAconcentrations 10 times higher than the ULN (p &lt; 0.001).Conclusion:A TTG IgA concentration 10 times above the ULN is significantly positively associated withMarsh grade 3 histopathological findings. The determination of specific antibodies incombination with HLA-DQ2/DQ8 typing appears sufficient for diagnosing CD, supporting thenotion that duodenal biopsy may be avoided in the majority of patients—77%.</ns1:description>
