Celiac disease (CD) is an autoimmune enteropathy triggered by the ingestion of dietary gluten from some cereals mainly in individuals carrying the HLA-DQ2 and/or HLA-DQ8 haplotypes. As an autoimmune disease, CD is manifested in the small intestine in the form of a progressive and reversible inflammatory lesion due to immune response to self-antigens. Indeed, CD is one of the most challenging medicosocial problems in current gastroenterology. At present, the global CD prevalence is estimated at approximately 1% based on data sent from different locations and available CD screening strategies used. However, it is impossible to estimate global CD prevalence without all the data from the world, including Russia. In this review, we summarize the data on the incidence and prevalence of CD across geographically distinct regions of Russia, which are mostly present in local Russian scientific sources. Our conclusion is that the situation of CD prevalence in Russia is higher than is commonly believed and follows global tendencies that correspond to the epidemiologic situation in Europe, America, and Southwest Asia.

Coeliac disease (CD) is an autoimmune enteropathy triggered by the ingestion of gluten-containing grains in genetically predisposed individuals. Identification of CD in clinical practice is often difficult due to the manifestation of non-specific symptoms and signs, so a relatively significant proportion of CD cases remain undiagnosed. Timely detection of the disease is necessary to provide an appropriate approach to control of the disease treatment, in order to avoid potential complications. This is even more important in the case of children and adolescents, to ensure their proper growth and development. In this review, we discuss the data on the current strategies for CD detection among paediatric populations and the role of questionnaire-based discovery of CD cases in the area of interest. We assume that mass screening is a preferable strategy for finding CD cases within the paediatric population because this could uncover symptomatic, oligosymptomatic, and asymptomatic CD cases. However, under conditions of limited financial resources, screening for CD in risk groups, members of which can be identified using questionnaires, is essential. The pros and cons of CD screening in paediatric populations are presented. These depend on a number of situational criteria (cost-effectiveness, lack of awareness), but screening is designed to improve the detection of the disease and therefore improve the quality of life of patients.

The prevalence of the celiac disease (CeD) is increasing worldwide, which is not only due to the modern capabilities of the latest laboratory and instrumental technologies but rather with a true rise in incidence. Despite recent advances in endoscopic imaging and serological tests, the accurate diagnosis of CeD remains challenging. Since the majority of patients are “asymptomatic” from the gastrointestinal aspects they come to medical attention because of other reasons than CeD and a large number of CeD passes undiagnosed. This fact highlights the need for improved strategies in the future for the optimal detection of patients and use of clear algorithms for diagnosing CeD. The review describes the global experience in diagnosing CeD and provides «step-by-step» recommendations to help specialists in medicine not only in cases with the usual classical manifestations of CeD, but also in complex clinical variants of this disease or for patients already following a gluten-free diet. Keywords: diagnostics of celiac disease, CeD, anemia, intestinal biopsy, non-gastrointestinal symptoms, serology for celiac disease, HLA testing, gluten-free diet.

Study objective. To optimize the recommendations on the strategy of enteral feeding for newborn babies with necrotizing enterocolitis (NEC). Patients and methods. A single-centre, observational, prospective, analytical, cohort study of 186 infants aged from 2 days to 2 months (96 boys, 90 girls) with the verified diagnosis of NEC of varied severity, who were treated at the neonatal pathology department of Moscow G.N.Speransky Children’s City Clinical Hospital No 9 in 2016-2018. The patients were divided into 2 groups, depending on disease staging according to the Walsh and Kliegman classification: group I – 124 (66.7%) newborns with mild NEC (stage 1A, B and 2A) and group II – 62 (33.3%) patients with a severe course (stages 2B and 3A, B). Results. As has been found, maternal risk factors for the development of severe forms of NEC in newborns are: maternal age over 40 years (OR = 1.40, 95% CI 0.83–2.17), assisted reproductive technologies (OR = 2.62, 95% CI 1.79–3.66), bad obstetrical-gynaecological history (OR = 1.80, 95% CI 1.03–2.97), infectious diseases during pregnancy (OR = 1.37, 95% CI 0.69–1.90). The ranking of the risk factors present in babies themselves permitted to find a causative relation with such factors as bacteriological contamination of biological media (OR = 2.80, 95% CI 1.3–4.0), bacteremia, viremia (OR = 5.80, 95% CI 2.99–7.13), gestational age 30–32 wks (OR = 2.35, 95% CI 1.01–3.94), which were significant only for mild forms of NEC. A minimal number of severe cases was diagnosed for a combination of breastfeeding and parenteral nutrition (16.7%), development of severe NEC was more often noted when feeding was started within 5 days: breastfeeding (26.3%), formula feeding (33.3 %), mixed breast and formula feeding (5%), or in infants who did not receive feeding due to their severe condition after birth (33%) (р < 0.05). The minimal number of severe NEC cases was found among babies who remained on breast (11.1%) and mixed (11.1%) feeding after the 5th day (р < 0.05), the maximal number – in infants who started from enteral feeding and were transferred to formula feeding (50%). Prolonged enteral feeding was three times more often associated with a severe course of NEC (р < 0.001). Conclusion. As has been found, the frequency of developing severe NEC depends on the character of the first feed after birth. A risk of developing severe forms of NEC decreases in newborns on breast- or mixed feeding, in combination of breast feeding and parenteral nutrition, short courses of enteral pauses, alternation of enteral feeding and enteral pauses. The results might be used in the clinical practice of neonatologists and paediatricians for prevention and management of NEC and its possible complications in newborn infants. Key words: necrotising enterocolitis, enteral pause, enteral nutrition, neonatology, birth weight, gestational age, premature infants

Aim Coeliac disease (CD) is a chronic digestive disorder which presents in diverse ways and is under‐diagnosed. The purpose of this study was to provide insights into suspected CD among Russian schoolchildren, through defining the percentage of participants in an ‘at‐risk’ group for CD in a paediatric cohort, by means of a questionnaire as a primary screening tool. Methods Russian school children of both sexes age 7‐18 years were enrolled in a population‐based study to identify individuals affected by CD. Each participant was presented with a structured questionnaire based on criteria that can be used to reveal symptomatic signs of CD. Following on, we developed a case‐finding strategy for the ‘at‐risk’ group, based on serological and genetic testing and, where possible, endoscopic examination of participants. Results 10.2% of questionnaire respondents (312/3070) were classified as an at‐risk group. Pathobiological CD analysis of this group returned positive test results for 13.5% of participants (42/312), and 0.6% of them (2/312) had CD confirmed by biopsy sample analysis. Conclusions Our findings suggest that at‐risk groups among children with symptomatic or some oligosymptomatic CD presentations can be identified through adopting a questionnaire as part of a population‐based screening survey, if generally accepted screening programs are inaccessible.
