Serological methods remain the main tool for screening for celiac disease. The most sensitive and specific markers of the disease are anti-tissue transglutaminase and anti-endomysium IgA antibodies, but the possibility of their use is limited by the concentration of serum total IgA. Due to the frequent association of celiac disease with selective immunoglobulin A deficiency, the search for diagnostic markers in this group of patients is relevant.</p></sec><sec><title>Аim</title><p>Аim. Тo evaluate the diagnostic value of serological markers of celiac disease in children with decreased serum immunoglobulin A.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The sensitivity, specificity, positive and negative predictive value of IgG antibodies to anti-tissue transglutaminase (anti-tTG IgG), deamidated gliadin peptides (anti- DPG IgG) and gliadin (AGA IgG) were analyzed in a group of 166 children aged 1 to 17 years, average age 6.04 years, with varying degrees of immunoglobulin A deficiency.</p></sec><sec><title>Results</title><p>Results. The incidence of celiac disease in symptomatic patients with decreased serum immunoglobulin A concentrations was 13.2%, increasing up to 20% in the group of patients with selective IgA deficiency. Anti-tTG IgG demonstrated high values of sensitivity, specificity and positive predictive value as 85%, 97.3% and 85%, respectively. With comparable sensitivity and specificity, anti- DPG IgG were significantly worse with positive predictive value (26.7%). AGA IgG showed the lowest diagnostic value. When analyzing the dependence of the degree of histological changes on the concentration of tTG IgG, no statistically significant correlation was determined.</p></sec><sec><title>Conclusions</title><p>Conclusions. Frequent association of gluten enteropathy with hypogammaglobulinemia A determines the need for active screening for celiac disease among children with these type of humoral immunity. Anti-tTG IgG demonstrate high diagnostic value in children with IgA deficiency, however, verification of the diagnosis of celiac disease in patients with hypogammaglobulinemia A requires mandatory endoscopic and histological studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>целиакия</kwd><kwd>дети</kwd><kwd>иммуноглобулин А</kwd><kwd>дефицит IgA</kwd><kwd>скрининг</kwd><kwd>серологические маркеры</kwd><kwd>антитела к тканевой трансглутаминазе</kwd><kwd>антитела к глиадину</kwd><kwd>антитела к деамидированным пептидам глиадина</kwd><kwd>чувствительность и специфичность серологических тестов</kwd><kwd>атрофическая энтеропатия по классификации Marsh- Oberhuber</kwd></kwd-group><kwd-group xml:lang="en"><kwd>celiac disease</kwd><kwd>children</kwd><kwd>immunoglobulin A</kwd><kwd>IgA deficiency</kwd><kwd>screening for celiac disease</kwd><kwd>serological markers</kwd><kwd>antibodies to tissue transglutaminase</kwd><kwd>antibodies to gliadin</kwd><kwd>antibodies to deamidated gliadin peptides</kwd><kwd>sensitivity and specificity of serological tests</kwd><kwd>atrophic enteropathy according to the Marsh-Oberhuber classification</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Боровик ТЭ, Захарова ИН, Потапов АС, Бельмер СВ, Хавкин АИ, Ревнова МО и др.
