OBJECTIVES: Response to a gluten-free diet (GFD) in children with celiac disease is determined by symptom resolution and normalization of serology. We evaluated the rate of normalization of the transglutaminase (TTG) and antiendomysial (EMA) for children on a GFD after diagnosis. METHODS: Celiac serologies were obtained over 3.5 years after starting a GFD in 228 newly diagnosed children with biopsy-proven celiac disease. Patients were classified into categories based on serology (group A, TTG ≥10 × upper limit of normal [ULN] and EMA ≥ 1:80; group B, TTG ≥10 × ULN and EMA ≤ 1:40; and group C, TTG <10 × ULN) and by severity of histologic injury at diagnosis...

PURPOSE OF REVIEW: The review aims to critically discuss the role of infant feeding in the development of celiac disease and type 1 diabetes (T1D). RECENT FINDINGS: Prospective observational and randomized interventional studies show that breastfeeding (BF) or BF during gluten introduction does not reduce the risk of developing CD, but high gluten consumption before age 2 years increased the risk in Swedish children.Despite evidence from retrospective studies, prospective trials failed to find a protective effect of breastfeeding against the risk of T1D development...

Background: We previously found that the introduction of small quantities of gluten at 4-6 mo of age did not reduce the risk of celiac disease (CD) in a group of high-risk children. However, the consumption of high amounts of gluten early in life has been suggested to increase CD risk.Objective: The aim of this study was to evaluate this hypothesis by using data from the previous study of the PreventCD trial (www.preventcd.com).Design: Gluten intake was prospectively quantified by using specific food records between 11 and 36 mo of age in 715 children positive for the human leukocyte antigen (HLA)-DQ2 and/or HLA-DQ8 from 5 European countries...

BACKGROUND AND OBJECTIVES: Psychological symptoms can be associated with celiac disease; however, this association has not been studied prospectively in a pediatric cohort. We examined mother report of psychological functioning in children persistently positive for tissue transglutaminase autoantibodies (tTGA), defined as celiac disease autoimmunity (CDA), compared with children without CDA in a screening population of genetically at-risk children. We also investigated differences in psychological symptoms based on mothers' awareness of their child's CDA status...

REVIEW
Consolato Sergi, Fan Shen, Gerd Bouma
The upper digestive tract is routinely scoped for several causes of malabsorption, and the number of duodenal biopsy specimens has increased notably in the last 10 years. Gluten-sensitive enteropathy (GSE) is an autoimmune disease, which shows an increasing prevalence worldwide and requires a joint clinico-pathological approach. The classical histopathology of GSE with partial or total villous blunting is well recognized, but the classification of GSE is not straightforward. Moreover, several mimickers of GSE with intraepithelial lymphocytosis have been identified in the last 20 years, with drug interactions and medical comorbidities adding to the conundrum...

Celiac disease (CD) is a severe genetic autoimmune disorder, affecting about one in 100 people, where the ingestion of gluten leads to damage in the small intestine. Diagnosing CD is quite complex and requires blood tests and intestinal biopsy examinations. Controversy exists regarding making the diagnosis without biopsy, due to the large spectrum of manifesting symptoms; furthermore, small-intestinal gastroscopy examinations have a relatively complex management in the pediatric population. To identify novel molecular markers useful to increase the sensitivity and specificity in the diagnosis of pediatric CD patients, the expression levels of two key autophagy executor genes (ATG7 and BECN1) and their regulatory validated miRNAs (miR-17 and miR-30a, respectively) were analyzed by relative quantitative real-time-PCR on a cohort of confirmed CD patients compared to age-related controls...

Celiac disease (CD) is an autoimmune disease with increasing prevalence in the USA. CD leads to decreased absorption of many nutrients including certain divalent metals. On the other hand, recent cross-sectional studies suggest the associations between trace heavy metal exposure and autoimmunity. We aimed to determine if there is an association between CD autoimmunity and blood levels of heavy metals in the general US population. We used nationally representative data from National Health and Nutrition Examination Survey, 2009-2012...

One of the hallmarks of Celiac disease (CD) is intraepithelial lymphocytosis in the small intestine. Until now, investigations to characterize the T cell subpopulations within the epithelial layer have not discriminated between the heterodimeric co-receptor molecule, CD8αβ, and the possibly immunoregulatory CD8αα homodimer molecule. Besides TCRαβ+ CD4+ cells, no other phenotypes have been shown to be gluten-reactive. Using flow cytometry on lymphocytes from duodenal biopsies, we determined that the number of B cells (CD3- CD19+) and the number of CD3+ CD4- CD8- double-negative (DN) T cells were elevated 6-7 fold in children with CD...

We present a 17-month-old girl with rapidly progressive unwillingness to sit, stand, play, and walk. Furthermore, she lacked appetite, vomited, lost weight, and had an iron deficiency. Physical examination revealed a cachectic, irritable girl with a distended abdomen, dystrophic legs with paraparesis, disturbed sensibility, and areflexia. An MRI scan revealed abnormal high signal intensity on T2-weighted images in the cord on the thoracic level, without cerebral abnormalities, indicating transverse myelitis (TM)...

OBJECTIVES: Celiac disease (CD) is a common immune-mediated disorder that affects up to 1% of the general population. Recent reports suggest that the incidence of CD has reached a plateau in many countries. We aim to study the incidence and altered presentation of childhood CD in a well-defined population. METHODS: Using the Rochester Epidemiology Project, we retrospectively reviewed Mayo Clinic and Olmsted Medical Center medical records from January 1994 to December 2014...

OBJECTIVE: The prevalence of Celiac Disease (CD) has increased significantly in recent years, and risk prediction and early diagnosis has become imperative especially in at risk families. In a previous study, we identified individuals with CD based on the expression profile of a set of candidate genes in peripheral blood monocytes. Here we evaluated the expression of a panel of CD candidate genes in peripheral blood mononuclear cells (PBMCs) from at risk infants long time before any symptom or production of antibodies...
