1. Introduction
Celiac Disease (CD) is an autoimmune disorder triggered by
gluten consumption in genetically susceptible individuals and
characterized by the presence of a specific enteropathy [1].
It exhibits an indreasing worldwide prevalence, specially
in North African Maghreb countries [2,3], and is frequently
reported to be associated with other autoimmune conditions [4].
Here is summarized a rare association combining CD,
Type1 Diabetes (T1D) and Crohn Disease (CrD).
2. Case Presentation
We report the case of a young male teenager aged
thirteen and suffering from type 1 diabetes from several
years and difficultly managed for his chronic, complicated
dysglycemia..
He was diagnosed with T1D at age of 6, but could not
achieve a balanced glycemia despite tight follow up and
increasing insulin doses.
He suffers from refractory, watery, painful diarrhea
since a couple of months is revealing a Celiac disease,
confirmed by both serology and histology.
However, a gluten free diet could not reequilibrate his
bowel and, specially, a capricious melena was noted; as
well as persistant dyspepsia.
In fine, the boy was diagnosed (on endoscopy and
histology) with a Crohn disease ... another autoimmune,
chronic and hard-to-manage, condition.
Human leukocyte antigen (HLA) typing was ordered
and confirmed the presence of both HLA DQ2 (leading to
CD and T1D susceptibility) and HLA DR4 (well
recognized as a severeity biomarker in CrD)
3. Discussion
Autoimmune diseases associated to CD are widely and
increasingly reported [4,5].
However, the peculiar association of these three
conditions (e.g CD, T1D and Crohn Disease) is very
uncommon: we performed a Medline search through
Pubmed® using the Medical Subheading (Mesh) terms:
"Diabetes Mellitus, Type 1", "Celiac Disease" and "Crohn
Disease" with a final search request:
"Diabetes Mellitus, Type 1"[Mesh]) AND "Celiac
Disease"[Mesh]) AND "Crohn Disease"[Mesh] "
Surprisingly, we retrieved only thirteen articles, and no
similar case report using the Pubmed® Search Filter:
‘‘Case Report’’. [6]
Several pathophysiological similarities may explain this
particular association:
-Immunity, at first: the autoimmune-related background
of CD is confirmed by the frequent associations between
different autoimmune disorders and CD. The association
of CD and autoimmune disorders can be explained by the
frequent finding of organ-specific autoantibodies, similar
lymphocyte and mononuclear cell infiltrations at target
organ level, and common HLA phenotypes [7].
- Genetics: mainly through the above mentioned HLA.
Associations between HLA antigens and autoimmune
diseases were reported since the 1970s. After the development
of wide-screen genotyping and finemapping, HLA was
increminated in major autoimmune diseases like CD,
Rheumatoid Arthritis, psoriasis, ankylosing spondylitis,
systemic lupus erythematosus, Type 1 Diabetes, multiple
sclerosis, Graves disease, and dermatomyositis [1,8]
CD is strongly associated with the HLA: more than
95% of patients with CD share the HLA-DQ2 heterodimer,
2 International Journal of Celiac Disease
and the remainder present the HLA-DQ8 heterodimer,
both located on chromosome 6 [9].
In a modern context of increased prevalence of CD as
well as other autoimmune diseases, HLA typing emerges
as an important tool to discriminate individuals genetically
susceptible to develop CD or T1D in at-risk groups such
as those with autoimmune conditions [10].
- Finally, the involvment of intestinal hyperpermeability in
the common genesis of these three conditions [11,12,13],
as well as the expending role of the gastrointestinal
microbiota [14,15,16], complete the puzzle of such an
"autoimmune implosion".
4. Conclusion
Several autoimmune disorders may share, at least
partially, the same immunogenetic core (i.e. HLA) that
could be analysed in the early management of targetted
autoimmune conditions in order to guide future treatment.
Keep in mind that an autoimmune dysregulation may
predispose to other ones with a potential deep impact on
clinical management.

Gut microbiota shapes the development of the mucosal immune system and may provide protection against immunemediated diseases. Celiac disease (CD) is a chronic inflammatory condition triggered by dietary gluten proteins, recently associated with gut microbiota alterations in cross-sectional studies comparing patients and controls. Whether or not these differences are causally related to the disease has yet to be elucidated, but evaluation of specific bacteria isolated from CD patients in experimental models suggests that they can promote an adverse response to dietary gluten, whereas other commensal bacteria can be protective. Genetic and environmental factors associated with increased CD risk have also been linked to shifts in the gut microbiota composition in infants early in life. Epigenetic mechanisms also seem to play an important role in modulating gut microbiota composition and function and, theoretically, could also influence CD risk. Here, we review the current knowledge on how host genetics, environmental factors, and epigenetic modifications could modulate gut microbiota functionality and how this may influence CD risk. Greater understanding of the role of this triad in CD onset and pathogenesis will be valuable in designing proof-of concept interventions in the gut ecosystem, with a view to improving CD management.

The gastrointestinal system represents one of the largest interfaces between the human internal microenvironment and the external world. This system harbors trillions of commensal bacteria that reside in symbiosis with the host. Intestinal bacteria play a crucial role in maintaining systemic and intestinal immune and metabolic homeostasis because of their effect on nutrient absorption and immune development and function. Recently, altered gut bacterial composition (dysbiosis) was hypothesized to be involved in mechanisms through which islet autoimmunity is triggered. Evidence from animal models indicates that alterations in the gut bacterial composition precede disease onset, thus implicating a causal role for the gut microbiome in islet destruction. However, it remains unclear whether dysbiosis is directly linked to the mechanisms of human type 1 diabetes (T1D). In this review, we discuss data implicating the gut microbiota in disease progression with an emphasis on our recent studies performed in humans and in rodent models of T1D.

Coeliac disease (CD), originally thought to be largely confined to Northern Europe and Australasia and uncommon in North America and the Middle East, is now recognised to be equally common in all these countries. It is still thought to be rare in the Orient and Sub-Saharan Africa. To assess geographical differences and time trends in the frequency of CD. Medline and Embase searches were conducted on 10 November 2012, from 1946 and 1980 respectively, using the key words: coeliac disease or celiac disease + prevalence or incidence or frequency. There were significant intra- and inter-country differences in the prevalence and incidence of CD. Only 24 ethnic Chinese and Japanese patients have been reported in the English literature. Of CD-associated HLA DQ antigens, DQ2 occurs in 5–10% of Chinese and sub-Saharan Africans, compared to 5–20% in Western Europe. DQ8 occurs in 5–10% of English, Tunisians and Iranians, but in <5% of Eastern Europeans, Americans and Asians. The prevalence and incidence of both clinically and serologically diagnosed CD increased in recent years. These geographical and temporal differences seem genuine, although variable indices of suspicion and availability of diagnostic facilities are confounding factors. Coeliac disease is increasing in frequency, with significant geographical differences. Although few cases have been described to date in the Orient and Sub-Saharan Africa, there is a significant prevalence of HLA DQ2 and wheat consumption is of the same order as that in Western Europe. CD may therefore become more common in the future in these countries.

Much has been written about the role of diet and risk for Crohn's disease (CD). However, the evidence is contradictory. Recent evidence has pointed to fiber playing an important role along with the possibility that dietary fat and overnutrition also have a role. Diet has a clearer place in disease modification, with some diets used in the treatment of CD. The lack of clarity stems from a poor understanding of the mechanisms underlying the relationship between diet and CD. Gut permeability is likely to play a key role in the risk for CD. Mechanisms whereby diet can affect gut permeability, including the effects of the gut microbiota, are reviewed. Modification of disease behavior is likely to be influenced by additional mechanisms, including recognition of complex food antigens. As with many other chronic diseases, a surrogate marker of CD risk would greatly aid evaluation of the dietary factors involved. Formal measures of gut permeability are too cumbersome for large-scale use, but fecal calprotectin may be a convenient measure of this. There are only preliminary data on the effect of diet and microbiota composition on fecal calprotectin and these require further investigation. Copyright © 2015 Elsevier Inc. All rights reserved.

The tight junction forms a barrier against unlimited paracellular passage but some of the tight junction proteins just do the opposite, they form extracellular channels zigzagging between lateral membranes of neighboring cells. All of these channel-forming proteins and even some of the barrier formers exhibit selectivity, which means that they prefer certain substances over others. All channel formers exhibit at least one of three types of selectivity: for cations (claudin-2, -10b, -15), for anions (claudin-10a, -17) or for water (claudin-2). Also some, but not all, barrier-forming claudins are charge-selective (claudin-4, -8, -14). Moreover, occludin and tricellulin turned out to be relevant for barrier formation against macromolecule passage. Tight junction proteins are dysregulated or can be genetically defective in numerous diseases, which may lead to three effects: (i) impaired paracellular transport e.g. causing magnesium loss in the kidney, (ii) increased paracellular transport of solutes and water e.g. causing leak-flux diarrhea in the intestine, and (iii) increased permeability to large molecules e.g. unwanted intestinal pathogen uptake fueling inflammatory processes. This review gives an overview on the properties of tight junction proteins featuring selective permeability, and in this context explains how these proteins induce or aggravate diseases.

Negative predictive value (NPV) of celiac disease (CD)-related human leukocyte antigens (HLA) DQ2 and DQ8 approaches 100 % in individual patients. However, studies evaluating its exclusionary utility in patient groups are lacking. We aim to assess the performance of HLA testing when applied to patient groups with varying characteristics and propose evidence-based recommendations for its clinical use. Demographic and clinical information was recorded in patients undergoing HLA testing. Using predetermined criteria, patients were classified as CD, non-CD, or indeterminate. Diagnostic yield of HLA testing was defined as the percentage of patients in whom CD could be excluded based on negative HLA test. Two hundred and fifty-six patients underwent testing for CD-related HLA DQ2 and DQ8. 102 (100 non-CD, 2 CD) patients tested HLA negative for a 98 % NPV and 39 % diagnostic yield. Diagnostic yield was highest (60 %) in patients with intraepithelial lymphocytosis plus normal IgA tissue transglutaminase antibody (IgA-tTG) and lowest in patients with positive IgA-tTG plus villous atrophy (0 %). CD was diagnosed in two HLA-negative patients, who carried half of DQ2.5 trans genotype. Diagnostic yield of CD-related HLA testing varies widely depending on clinical indication. HLA testing is a practical and valuable test for most patients in whom initial evaluation for CD is inconclusive. A negative HLA result usually obviates the need for further celiac testing including endoscopy and gluten challenge. Rarely, in patients reported as HLA negative, half of HLA DQ2.5 (cis or trans) is sufficient for development of CD.

Increased small intestinal permeability is a longstanding observation in both Crohn's disease patients and in their healthy, asymptomatic first-degree relatives. However, the significance of this compromised gut barrier function and its place in the pathogenesis of the disease remains poorly understood. The association between abnormal small intestinal permeability and a specific mutation in the NOD2 gene, which functions to modulate both innate and adaptive immune responses to intestinal bacteria, suggests a common, genetically determined pathway by which an abnormal gut barrier could result in chronic intestinal inflammation. Furthermore, rodent colitis models show that gut barrier defects precede the development of inflammatory changes. However, it remains possible that abnormal permeability is simply a consequence of mucosal inflammation. Further insight into whether abnormal barrier function is the cause or consequence of chronic intestinal inflammation will be crucial to understanding the role of intestinal permeability in the pathogenesis of Crohn's disease.

The occurrence of autoimmune disorders and organ-specific autoantibodies has been reported in coeliac disease. We assessed the prevalence of organ-specific autoantibodies in coeliac patients and evaluated whether their finding is an expression of associated autoimmune diseases. Sera from 70 coeliac disease patients were tested for thyroid microsomal, gastric parietal cell, adrenal cortex and pancreatic islet cell antibodies by indirect immunofluorescence on O blood group human tissues. Eighteen coeliacs (26%) were positive for at least one of the autoantibodies studied; thyroid microsomal antibodies showed a higher prevalence (21%) than parietal cell (11%), adrenal cortex (4%) and islet cell antibodies (3%). In 15 (21%) of the 70 coeliacs studied an association with autoimmune diseases was found, including insulin dependent diabetes mellitus (6 cases), autoimmune hepatitis (3 cases), hypothyroidism (4 cases), thyrotoxicosis (1 case) and dermatomyositis (1 case). One or more organ-specific autoantibodies were positive in 12 (80%) of the 15 coeliacs with autoimmune disorders in comparison with their positivity in 6 (11%) of the 55 coeliacs without autoimmune diseases (p < 0.0001). The finding of organ-specific autoantibodies in coeliac patients discloses the coexistence of a wide spectrum of immunological diseases.
