Background: Several studies have shown that the knowledge about coeliac disease (CD) is not satisfactory among healthcare professionals (HCP). The aim of our study was to assess the knowledge of HCPs about CD in the Danube region., Methods: HCPs from 8 countries in the Danube region were asked to complete the web-based questionnaire about CD. Scores of HCPs were compared according to their speciality, work experience and country of residence. The results were compared with the results of a similar study conducted in Central Europe within the Focus IN CD project in 2016., Results: Questionnaire was completed by 799 HCPs from Austria, Croatia, Czech Republic, Hungary, Moldova, Romania, Serbia, and Slovenia. Mean score achieved by HCPs was 52.2%. Paediatric gastroenterologists scored the highest (75.3%). Comparing the data with the study conducted in Central Europe in 2016, we found a significant rise (p < 0.001) in the knowledge of paediatric gastroenterologists. Also, HCPs who previously took part in the Focus IN CD project, achieved higher score (61.1% vs. 50.8%; p < 0.001)., Conclusion: The knowledge about CD among HCPs in Danube region is not satisfactory. There has been a significant increase in the knowledge of paediatric gastroenterologists, showing the benefit of various awareness raising activities that were carried out recently., (© 2024.

Background: Recently published paediatric guidelines for diagnosing coeliac disease do not include recommendations on the follow-up of coeliac disease patients., Goal: The aim of this study was to assess the management practices and experience of coeliac disease patients with their follow-up appointments in Central Europe., Study: Gastroenterologists and coeliac disease patients in five Central European countries were asked to complete the web-based questionnaire focusing on coeliac disease management practices., Results: Answers from 147 gastroenterologists and 2041 coeliac disease patients were available for the analysis. More than half of the gastroenterologists (58.5%) schedule the first follow-up visit within 3 months after the diagnosis. At follow-up, tissue transglutaminase antibodies are checked in almost all patients (95.9%). Approximately two-thirds (60.7%) of gastroenterologists refer all of their patients to the dietitian at diagnosis. Similarly, 42.8% of coeliac disease patients reported that they had not been appointed to a dietitian. Almost one-third of coeliac disease patients (30.8%) reported that they had no follow-up appointments with gastroenterologist at all., Conclusions: Follow-up of coeliac disease patients is suboptimal in Central Europe. Many patients are not followed regularly. A lot of patients are not referred to a dietitian. The recommendations on the optimal follow-up of coeliac disease patients are needed in order to improve patient care., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Objectives: Celiac disease (CD) remains undiagnosed for a long time in many adult and pediatric patients. We assessed the knowledge about CD among healthcare professionals (HCPs) and CD patients in Central Europe (CE)., Methods: HCPs and CD patients from 5 CE countries were asked to complete the web-based questionnaire about CD. The questions were divided into subsections on epidemiology, clinical presentation, diagnostics, treatment, and follow-up. Achieved scores of different specialists managing patients with CD were compared and regional differences in patients' knowledge were analyzed., Results: Questionnaire was completed by 1381 HCPs and 2262 CD patients or their caregivers from Croatia, Hungary, Germany, Italy, and Slovenia. Mean score achieved by HCPs was 50.9%, and by CD patients 56.4%. Pediatric gastroenterologists scored the highest (69.4%; P < 0.001). There were significant differences in knowledge of patients from different CE regions with German participants scoring the highest (58.3%). Members of CD societies scored higher compared with nonmembers (mean score 58% vs 53.2%; P < 0.001) and patients diagnosed less than 5 years ago scored higher compared with those diagnosed more than 10 years ago (mean score 57.3% vs 54.6%; P < 0.001)., Conclusions: The knowledge about CD among HCPs and CD patients is not satisfactory. Further awareness-raising and learning activities are needed to improve HCPs' knowledge and to minimize the number of unrecognized patients and unnecessary diagnostic delays. Patients should be better informed about their disease to reach higher compliance with the gluten-free diet., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: During the past decades, there has been a shift in the clinical presentation of coeliac disease (CD) to nonclassical, oligosymptomatic, and asymptomatic forms. We assessed clinical presentation of CD in children and adolescents in Central Europe., Methods: Paediatric gastroenterologists in 5 countries retrospectively reported data of their patients diagnosed with CD. Clinical presentation was analyzed and the differences among very young (<3 years) and older children and adolescents were studied., Results: Data from 653 children and adolescents (median age 7 years 2 months; 63.9% girls) from Croatia, Germany, Hungary, Italy, and Slovenia were available for the analysis. One fifth (N = 134) of all children were asymptomatic. In symptomatic children, the most common leading symptom was abdominal pain (33.3%), followed by growth retardation (13.7%) and diarrhoea (13.3%). The majority of symptomatic children (47.6%; N = 247) were polysymptomatic. Abdominal pain was the most common symptom in polysymptomatic (66.4%) as well as in monosymptomatic children (29.7%). Comparing clinical presentation of CD in very young children (younger than 3 years) with older children (3 years or older), we found that symptoms and signs of malabsorption were significantly more common in younger (P < 0.001), whereas abdominal pain and asymptomatic presentation were more common in older children and adolescents (both P < 0.001)., Conclusion: In children with CD, abdominal pain has become the most common symptom. However, in younger children, symptoms of malabsorption are still seen frequently. This raises a question about the underlying mechanism of observed change in clinical presentation in favour of nonclassical presentation and asymptomatic disease at certain age., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

Objectives: Coeliac disease (CD) is a systemic autoimmune disorder affecting about 1% of the population. Many patients remain undiagnosed or are diagnosed with substantial delay. We assessed diagnostic delays in symptomatic CD children in Central Europe (CE)., Methods: Paediatric gastroenterologists in 5 CE countries retrospectively reported data of their patients diagnosed in 2016. Age at first CD-related symptom(s), first visit to paediatric gastroenterologist and confirmed diagnosis were used to determine diagnostic delays., Results: Data from 393 children (65% girls, median age 7 years, range 7 months to 18.5 years) from Croatia, Hungary, Germany, Italy, and Slovenia were analysed. Median duration from first symptom(s) to visit to paediatric gastroenterologist was 5 months (range 0-10 years; preschool 4 months, school-aged 5 months), and further duration until final diagnosis was 1 month (range 0-5 years) with significant regional differences (P < 0.001). Median diagnostic delay was 6 months (range 0-10 years; preschool 5 months, school-aged 7 months). Type of clinical presentation had little, however, significant effect on delays. Reduced body mass in delays longer than 3 years compared with delays shorter than 1 year was found (z score -0.93 vs -0.39, P < 0.05)., Conclusions: Time from first symptoms to CD diagnosis in children in 5 CE countries is slightly shorter compared with few other small paediatric studies, and significantly shorter than reported for adults. Nevertheless, delays of more than 3 years in 6.6% of children are worrisome. Raising awareness about the variable symptoms and implementation of reliable diagnostic tools will further reduce diagnostic delays.

Background & Aims: The guidelines of the European Society of Pediatric Gastroenterology, Hepatology, and Nutrition allow for diagnosis of celiac disease without biopsies in children with symptoms and levels of immunoglobulin A against tissue-transglutaminase (TGA-IgA) 10-fold or more the upper limit of normal (ULN), confirmed by detection of endomysium antibodies (EMA) and positivity for HLA-DQ2/DQ8. We performed a large, international prospective study to validate this approach., Methods: We collected data from consecutive pediatric patients (18 years or younger) on a gluten-containing diet who tested positive for TGA-IgA from November 2011 through May 2014, seen at 33 pediatric gastroenterology units in 21 countries. Local centers recorded symptoms; measurements of total IgA, TGA, and EMA; and histopathology findings from duodenal biopsies. Children were considered to have malabsorption if they had chronic diarrhea, weight loss (or insufficient gain), growth failure, or anemia. We directly compared central findings from 16 antibody tests (8 for TGA-IgA, 1 for TGA-IgG, 6 for IgG against deamidated gliadin peptides, and 1 for EMA, from 5 different manufacturers), 2 HLA-DQ2/DQ8 tests from 2 manufacturers, and histopathology findings from the reference pathologist. Final diagnoses were based on local and central results. If all local and central results were concordant for celiac disease, cases were classified as proven celiac disease. Patients with only a low level of TGA-IgA (threefold or less the ULN) but no other results indicating celiac disease were classified as no celiac disease. Central histo-morphometry analyses were performed on all other biopsies and cases were carefully reviewed in a blinded manner. Inconclusive cases were regarded as not having celiac disease for calculation of diagnostic accuracy. The primary aim was to determine whether the nonbiopsy approach identifies children with celiac disease with a positive predictive value (PPV) above 99% in clinical practice. Secondary aims included comparing performance of different serological tests and to determine whether the suggested criteria can be simplified., Results: Of 803 children recruited for the study, 96 were excluded due to incomplete data, low level of IgA, or poor-quality biopsies. In the remaining 707 children (65.1% girls; median age, 6.2 years), 645 were diagnosed with celiac disease, 46 were found not to have celiac disease, and 16 had inconclusive results. Findings from local laboratories of TGA-IgA 10-fold or more the ULN, a positive result from the test for EMA, and any symptom identified children with celiac disease (n = 399) with a PPV of 99.75 (95% confidence interval [CI], 98.61-99.99); the PPV was 100.00 (95% CI, 98.68-100.00) when only malabsorption symptoms were used instead of any symptom (n = 278). Inclusion of HLA analyses did not increase accuracy. Findings from central laboratories differed greatly for patients with lower levels of antibodies, but when levels of TGA-IgA were 10-fold or more the ULN, PPVs ranged from 99.63 (95% CI, 98.67-99.96) to 100.00 (95% CI, 99.23-100.00)., Conclusions: Children can be accurately diagnosed with celiac disease without biopsy analysis. Diagnosis based on level of TGA-IgA 10-fold or more the ULN, a positive result from the EMA tests in a second blood sample, and the presence of at least 1 symptom could avoid risks and costs of endoscopy for more than half the children with celiac disease worldwide. HLA analysis is not required for accurate diagnosis. Clinical Trial Registration no: DRKS00003555., (Copyright © 2017 AGA Institute. Published by Elsevier Inc. All rights reserved.)
