Pérez-Pérez M, Ferreira T, Igrejas G, Fdez-Riverola F. A novel gluten knowledge base of potential biomedical and health-related interactions extracted from the literature: using machine learning and graph analysis methodologies to reconstruct the bibliome. J Biomed Inform 2023:104398. [PMID: 37230405 DOI: 10.1016/j.jbi.2023.104398] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 05/12/2023] [Accepted: 05/15/2023] [Indexed: 05/27/2023]
Abstract
BACKGROUND In return for their nutritional properties and broad availability, cereal crops have been associated with different alimentary disorders and symptoms, with the majority of the responsibility being attributed to gluten. Therefore, the research of gluten-related literature data continues to be produced at ever-growing rates, driven in part by the recent exploratory studies that link gluten to non-traditional diseases and the popularity of gluten-free diets, making it increasingly difficult to access and analyse practical and structured information. In this sense, the accelerated discovery of novel advances in diagnosis and treatment, as well as exploratory studies, produce a favourable scenario for disinformation and misinformation. OBJECTIVES Aligned with, the European Union strategy "Delivering on EU Food Safety and Nutrition in 2050" which emphasizes the inextricable links between imbalanced diets, the increased exposure to unreliable sources of information and misleading information, and the increased dependency on reliable sources of information; this paper presents GlutKNOIS, a public and interactive literature-based database that reconstructs and represents the experimental biomedical knowledge extracted from the gluten-related literature. The developed platform includes different external database knowledge, bibliometrics statistics and social media discussion to propose a novel and enhanced way to search, visualise and analyse potential biomedical and health-related interactions in relation to the gluten domain. METHODS For this purpose, the presented study applies a semi-supervised curation workflow that combines natural language processing techniques, machine learning algorithms, ontology-based normalization and integration approaches, named entity recognition methods, and graph knowledge reconstruction methodologies to process, classify, represent and analyse the experimental findings contained in the literature, which is also complemented by data from the social discussion. RESULTS and Conclusions: In this sense, 5,814 documents were manually annotated and 7,424 were fully automatically processed to reconstruct the first online gluten-related knowledge database of evidenced health-related interactions that produce health or metabolic changes based on the literature. In addition, the automatic processing of the literature combined with the knowledge representation methodologies proposed has the potential to assist in the revision and analysis of years of gluten research. The reconstructed knowledge base is public and accessible at https://sing-group.org/glutknois/.

Point-of-Care Screening for Coeliac Disease in Schoolchildren Reveals Higher Disease Prevalence in Croatia. Healthcare (Basel) 2022; 11:healthcare11010064. [PMID: 36611524 PMCID: PMC9819334 DOI: 10.3390/healthcare11010064] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/16/2022] [Accepted: 12/21/2022] [Indexed: 12/28/2022] Open
Abstract
Coeliac disease (CD) is an immune-mediated inflammatory disease triggered by dietary gluten and related proteins in genetically predisposed individuals. Point-of-care (POC) methods are non-invasive and easily performed tests, which could help to reduce the diagnostic delay of CD. The aim of our study was to determine the prevalence of CD using rapid POC test in first-grade schoolchildren in Zagreb, Croatia. A rapid qualitative immunoassay POC test designed for detection of immunoglobulin (Ig) A and IgG deamidated gliadin antibodies (DGP), as well as total IgA (to identify IgA deficient patients) in whole blood, was used to test healthy children on gluten containing diet. Out of 1404 tested children (51% female), 85 (6.05%) had a positive rapid POC test result and were referred to paediatric gastroenterologist. Finally, 7 children were diagnosed with CD (0.5%). There was no significant difference in children with CD and children with positive POC but negative serology in sex, BMI, or symptoms. However, children diagnosed with CD complained of abdominal pain significantly more often. The prevalence of CD in first-grade schoolchildren was 1:200 (0.5%), higher than in previous studies performed in Croatia. The results imply the possible benefit of IgA and IgG DGP-based POC tests in population screening.

Abstract
Celiac disease (CD) is a chronic immune-mediated intestinal disease that is characterized by production of autoantibodies directed against the small intestine. The main clinical manifestations of CD are typically defined as those related to indigestion and malabsorption. These manifestations include unexplained diarrhea or constipation, abdominal pain, bloating, weight loss, anemia, failure-to-thrive in children, and decreased bone density. Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by heterogeneous clinical manifestations, which may also involve the gastrointestinal tract. Comorbidity of CD and SLE is rare, and the overlapping symptoms and nonspecific clinical presentation may pose a diagnostic challenge to clinicians. We report here a case of SLE with CD, which mainly manifested as recurrent diarrhea, uncorrectable electrolyte disorders, and severe malnutrition. Through review, we hope to further improve our understanding and diagnostic level of this combination of diseases.

Abstract
Introduction Introduction: celiac patients suffer deficiencies before and during their maintenance of a gluten-free diet. This is due to malabsorption, associated with the disease, and to non-enriched, mostly processed foods high in saturated fats and deficient in the minerals typically present in wheat. Objectives: the main objective of this review was to determine the molecular basis of celiac disease and the nutritional deficiencies that gluten-free diet entails, as well as an assessment of gluten-free diet and its nutritional deficiencies once the intestinal microvilli have been restored. Material and methods: a bibliographic search was carried out through electronic databases. The content of the review focuses on the pathogenesis of celiac disease and the assessment of gluten-free diet when established for treatment. Results: the main deficiencies that occur in untreated celiac patients are (calcium, iron, fiber, folic acid, omega-3, vitamin B12, and vitamin D). It has been observed that the quality of life of celiac patients, after starting treatment, is reduced, and this leads to low adherence to gluten-free diet. In addition, these gluten-free diets without proper follow-up by a nutritionist entail other deficits such as: an increase in the risk of cardiovascular, metabolic, overweight and obesity diseases. Conclusion: gluten-free diet, as followed by celiac patients, usually entails certain deficiencies such as group-B vitamins, vitamin D, calcium, iron, folic acid, and fiber, which is mainly due to the poor nutritional quality of gluten-free products as compared to their equivalents with gluten, and a scarce monitoring by health professionals.

Abstract
Gluten free diet is the only available treatment for celiac disease (CeD). Patients with CeD who do not adhere to a strict gluten-free diet (GFD) have been found to have complications involving nutritional deficiencies, increased risk of bone fractures, increased risk of mortality, and certain types of cancers. Complete removal of gluten from the diet in a patient with CeD often results in symptomatic, serologic, and histologic remission. However, strict compliance with the diet is challenging. Long-term follow-up care is needed to assure treatment compliance and positive health outcomes. Monitoring celiac specific serology, nutrient deficiencies, bone mineral density, and assessment of GFD compliance have been recommended in clinical practice. However, there is no consensus on which specific tests and how often they should be performed during the follow up. Here, we have performed a review of the literature on current strategies to follow up patients with CeD. There are new tools for monitoring adherence to the GFD which could change some paradigms in following up treated patients.

Abstract
Background This study aimed to investigate ovarian reserve in patients of reproductive age with Celiac disease (CD) using anti-Müllerian hormone (AMH) levels, antral follicle counts (AFCs), and ovarian volume. Material/Methods We included into this study 46 CD female patients and 40 healthy female subjects of reproductive age, ages 18–45 years. Venous blood samples were taken from both groups on days 2–4 of the menstrual cycle, and follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), prolactin (PRL), and AMH levels were measured. On the same day, AFCs and ovarian volumes were determined. Data on body mass index (BMI), gravidity/parity/abortions/alive counts, disease duration, and Marsh histological classification were recorded. Results There were no statistically significant differences between CD and control groups in terms of mean age, BMI, or median gravidity/parity/abortions/alive counts (p>0.05). Also, there were no statistically significant differences between the 2 groups in terms of mean FSH, LH, E2, PRL levels, right and left ovarian volumes, and median right and left ovarian AFCs (p>0.05). However, AMH level was significantly lower in the CD group (p=0.032). No statistically significant correlation was found between AMH levels and age, BMI, FSH, LH, E2, PRL levels, right and left ovarian volumes, right and left ovarian AFCs, or Marsh histological classification using the Spearman correlation test (p>0.05). However, an inverse correlation was detected showing that AMH levels decrease with increasing CD duration (r=−0.054, p=0.001). Conclusions We found that AMH level and ovarian reserve was decreased in CD patients of reproductive age compared to healthy controls, and that AMH level and ovarian reserve decreased with increasing disease duration in CD patients.

Abstract
BACKGROUND The diagnosis of celiac disease (CeD) in clinical practice relies on serological testing for IgA antibodies to human tissue transglutaminase (anti-tTG) which diagnose CeD autoimmunity. We compared three kits for their performance in diagnosis of the disease and evaluated the point prevalence of CeD autoimmunity in a South Indian urban population. METHODS In the first part of the study, sera from 90 patients with documented CeD and 92 healthy controls were tested for anti-tTG using three different kits. One thousand nine hundred and seventeen healthy adults residing in urban areas of Vellore and Kancheepuram districts were tested for CeD autoimmunity using a sequential two-test strategy. RESULTS The sensitivity, specificity, false positivity, false negativity, positive predictive value, and negative predictive value for the three assays respectively were as follows: 95.5%, 82.6%, 17.3%, 4.4%, 84.3%, and 95% for the Aeskulisa New Generation Assay; 85.5%, 100%, 0%, 14.4%, 100%, and 87.6% for Quanta Lite; and 71.1%, 100%, 0%, 28.8%, 100%, and 71% for Celiac Microlisa. The ROC curves showed good discrimination for all three ELISAs with an AUC of 0.947, 0.950, and 0.886 for the Aeskulisa, Quanta Lite, and Celiac Microlisa, respectively. Of 1917 (males 908, females 1009) healthy adults, 113 (5.89%) were seropositive for IgA anti-htTG in the Aeskulisa test. Two of the latter tested positive in the Quanta Lite assay and/or the Celiac Microlisa assay. The CeD autoimmunity prevalence in this urban population was 1.0 per thousand (95% confidence interval 0.3 to 3.7 per thousand). CONCLUSION Sequential testing for anti-tTG using first a highly sensitive assay followed by a very specific assay is a new strategy for screening for CeD in clinical practice.

Abstract
Celiac disease (CD) is a systemic immune-mediated disorder triggered by dietary gluten in genetically predisposed individuals. The typical symptoms are anemia, diarrhea, fatigue, weight loss, and abdominal pain. CD has been reported in patients with primary sclerosing cholangitis, primary biliary cholangitis, autoimmune hepatitis, aminotransferase elevations, nonalcoholic fatty liver disease, hepatitis B, hepatitis C, portal hypertension and liver cirrhosis. We evaluate recommendations for active screening for CD in patients with liver diseases, and the effect of a gluten-free diet in these different settings. Active screening for CD is recommended in patients with liver diseases, particularly in those with autoimmune disorders, steatosis in the absence of metabolic syndrome, noncirrhotic intrahepatic portal hypertension, cryptogenic cirrhosis, and in the context of liver transplantation. In hepatitis C, diagnosis of CD can be important as a relative contraindication to interferon use. Gluten-free diet ameliorates the symptoms associated with CD; however, the associated liver disease may improve, remain the same, or progress.

Abstract
PURPOSE Celiac disease (CD) affects approximately 1% of the population, and although it remains largely underdiagnosed, can have considerable long-term morbidity. Common presenting symptoms include gastrointestinal complaints and weight loss, which are also symptoms seen in patients with eating disorders (EDs). Because of this overlap, and the importance of early diagnosis of CD and identifying possible complicating factors in patients with EDs, screening in our program has become part of an initial assessment during the past 4 years. METHODS A retrospective chart review of all patients ages 7-22 years seen in our Division of Adolescent Medicine for an ED evaluation from 2011 to 2014 were reviewed. Screening for CD was done with tissue transglutaminase IgA antibody (TTgAb) and anti-endomysial IgA antibody (aEAb). Immunoglobulin A (IgA) was also measured. RESULTS There were 1160 patients evaluated for an ED between 2011 and 2014, and 42.6% (494) were screened for CD during this time. Of those patients screened for CD the mean age was 16.0, compared to a mean age of 15.6 for those that were not screened, and 87.7% were female, compared to 84.7% of the unscreened group. Of the 494 screened, 10 (2%) screened positive with a TTgAb IgA EIA >20. Of the 10 who screened positive via blood test, four had biopsy confirmed CD via endoscopy, for an overall 0.8% prevalence in this cohort. Of the 457 patients who were also screened for IgA deficiency (92%), 5 (1.1%) had low IgA levels. CONCLUSION In this cohort of patients being evaluated for an ED, 0.8% had biopsy confirmed CD. This is similar to the reported prevalence in the general population, suggesting that routine screening of patients with EDs for CD is not indicated. We still need to be vigilant, however, for subtle symptoms that may indicate underlying CD in a small percentage of patients with EDs.
