Abstract
Celiac disease (CD) is well recognized as a systemic, chronic autoimmune disease mainly characterized by gluten-sensitive enteropathy in genetically predisposed individuals but with various extraintestinal features. One of the affected organs in CD is the pancreas, consisting of both endocrine and exocrine alterations. Over the last decades there has been increasing interest in the pancreatic changes in CD, and this has been reflected by a great number of publications looking at this extraintestinal involvement during the course of CD. While pancreatic endocrine changes in CD, focusing on type 1 diabetes mellitus, are well documented in the literature, the relationship with the exocrine pancreas has been less studied. This review summarizes currently available evidence with regard to pancreatic exocrine alterations in CD, focusing on risk of pancreatitis in CD patients, association with autoimmune pancreatitis, prevalence and outcomes of pancreatic exocrine insufficiency in newly diagnosed and gluten-free diet treated CD patients, and the link with cystic fibrosis. In addition, we discuss mechanisms behind the associated pancreatic exocrine impairment in CD and highlight the recommendations for clinical practice.

Abstract
Exocrine pancreatic insufficiency (EPI) causes chronic digestive dysfunction in cats, but its pathogenesis and pathophysiology are poorly understood. Untargeted metabolomics is a promising analytic methodology that can reveal novel metabolic features and biomarkers of clinical disease syndromes. The purpose of this preliminary study was to use untargeted analysis of the serum metabolome to discover novel aspects of the pathobiology of EPI in cats. Serum samples were collected from 5 cats with EPI and 8 healthy controls. The diagnosis of EPI was confirmed by measurement of subnormal serum feline trypsin-like immunoreactivity (fTLI). Untargeted quantification of serum metabolite utilized ultra-high-performance liquid chromatography-tandem mass spectroscopy. Cats with EPI had significantly increased serum quantities of long-chain fatty acids, polyunsaturated fatty acids, mevalonate pathway intermediates, and endocannabinoids compared with healthy controls. Diacylglycerols, phosphatidylethanolamines, amino acid derivatives, and microbial metabolites were significantly decreased in cats with EPI compared to healthy controls. Diacyclglycerols and amino acid metabolites were positively correlated, and sphingolipids and long-chain fatty acids were negatively correlated with serum fTLI, respectively. These results suggest that EPI in cats is associated with increased lipolysis of peripheral adipose stores, dysfunction of the mevalonate pathway, and altered amino acid metabolism. Differences in microbial metabolites indicate that feline EPI is also associated with enteric microbial dysbiosis. Targeted studies of the metabolome of cats with EPI are warranted to further elucidate the mechanisms of these metabolic derangements and their influence on the pathogenesis and pathophysiology of EPI in cats.

Abstract
AIMS In exocrine pancreatic insufficiency (EPI), the quantity and/or activity of pancreatic digestive enzymes are below the levels required for normal digestion, leading to maldigestion and malabsorption. Diagnosis of EPI is often challenging because the characteristic signs and symptoms overlap with those of other gastrointestinal conditions. Additionally, there is no single convenient, or specific diagnostic test for EPI. The aim of this review is to provide a framework for differential diagnosis of EPI vs other malabsorptive conditions. METHODS This is a non-systematic narrative review summarising information pertaining to the aetiology, diagnosis and management of EPI. RESULTS Exocrine pancreatic insufficiency may be caused by pancreatic disorders, including chronic pancreatitis, cystic fibrosis, pancreatic resection and pancreatic cancer. EPI may also result from extra-pancreatic conditions, including coeliac disease, Zollinger-Ellison syndrome and gastric surgery. Timely and accurate diagnosis of EPI is important, as delays in treatment prolong maldigestion and malabsorption, with potentially serious consequences for malnutrition, overall health and quality of life. Symptoms of EPI are non-specific; therefore, a high index of clinical suspicion is required to make a correct diagnosis.

Abstract
BACKGROUND Although the incidence of acute pancreatitis (AP) in children is increasing, management recommendations rely on adult published guidelines. Pediatric-specific recommendations are needed. METHODS The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Pancreas committee performed a MEDLINE review using several preselected key terms relating to management considerations in adult and pediatric AP. The literature was summarized, quality of evidence reviewed, and statements of recommendations developed. The authorship met to discuss the evidence, statements, and voted on recommendations. A consensus of at least 75% was required to approve a recommendation. RESULTS The diagnosis of pediatric AP should follow the published INternational Study Group of Pediatric Pancreatitis: In Search for a CuRE definitions (by meeting at least 2 out of 3 criteria: (1) abdominal pain compatible with AP, (2) serum amylase and/or lipase values ≥3 times upper limits of normal, (3) imaging findings consistent with AP). Adequate fluid resuscitation with crystalloid appears key especially within the first 24 hours. Analgesia may include opioid medications when opioid-sparing measures are inadequate. Pulmonary, cardiovascular, and renal status should be closely monitored particularly within the first 48 hours. Enteral nutrition should be started as early as tolerated, whether through oral, gastric, or jejunal route. Little evidence supports the use of prophylactic antibiotics, antioxidants, probiotics, and protease inhibitors. Esophago-gastro-duodenoscopy, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasonography have limited roles in diagnosis and management. Children should be carefully followed for development of early or late complications and recurrent attacks of AP. CONCLUSIONS This clinical report represents the first English-language recommendations for the management of pediatric AP. Future aims should include prospective multicenter pediatric studies to further validate these recommendations and optimize care for children with AP.

Abstract
Celiac disease (CD) is an autoimmune small intestinal mucosal disorder that often presents with diarrhea, malabsorption and weight loss. Often, one or more associated endocrine disorders may be associated with CD. For this review, methods involved an extensive review of published English-language materials. In children and adolescents, prospective studies have demonstrated a significant relationship to insulin-dependent or type 1 diabetes, whereas in adults, autoimmune forms of thyroid disease, particularly hypothyroidism, may commonly co-exist. In some with CD, multiple glandular endocrinopathies may also occur and complicate the initial presentation of the intestinal disease. In others presenting with an apparent isolated endocrine disorder, serological screening for underlying subclinical CD may prove to be positive, particularly if type 1 diabetes, autoimmune thyroid or other autoimmune endocrine diseases, such as Addison’s disease are first detected. A number of reports have also recorded hypoparathyroidism or hypopituitarism or ovarian failure in CD and these may be improved with a strict gluten-free diet.

Abstract
BACKGROUND Although exocrine pancreatic insufficiency (EPI) has been reported in a number of patients with celiac disease (CD), it is not clear if this is primarily a functional or a structural defect. We studied pancreatic structural abnormalities by endoscopic ultrasound (EUS) in adult CD patients with EPI. METHODS Pancreatic exocrine function was prospectively assessed in 36 recently diagnosed CD patients (mean age: 29.8 years) by measuring fecal elastase. Pancreatic structural changes were assessed in CD patients with EPI by EUS and elastography. Exocrine functions were reassessed after 3 months of gluten-free diet. RESULTS Of the 36 CD patients included, 30 (83%) had anemia, 21 (58%) diarrhea, and 7 (19%) hypothyroidism. Ten (28%) patients had EPI with mean elastase levels of 141.6 μg/g of stool, of whom only one had a history of recurrent acute pancreatitis while the rest 9 patients had no history of acute or chronic pancreatitis. Of these 10 patients, 8 (80%) had diarrhea, 8 (80%) anemia, and 2 (20%) hypothyroidism. EUS was done in 8 patients which showed: normal pancreas in 5 (50%), hyperechoic strands in 3 (30%), and hyperechoic foci without shadowing in 2 (20%) patients. None had lobularity or parenchymal calcification. All patients except the patient with recurrent pancreatitis had normal strain ratio. Follow-up fecal elastase was within normal range in 6 of 7 (86%) patients. CONCLUSION EPI, assessed by fecal elastase levels in adult CD patients, possibly does not relate to structural alterations in the pancreatic parenchyma and may be reversible by following a gluten-free diet.

Abstract
OBJECTIVES To determine whether exocrine pancreatic function is impaired in patients with coeliac disease (CD) in our population and to evaluate its clinical importance. METHODS Pancreatic exocrine function was determined by measuring faecal elastase-1 (FE) concentration. CD was diagnosed by serological testing using IgA anti-tissue transglutaminase antibody (IgAtTg) and small bowel biopsy using the Marsh classification. MRI of the pancreas was performed to evaluate any morphological changes. The study took place from January 2012 to December 2013. RESULTS 90 patients (73 women and 17 men) of mean age 43.8±17.7 years (range 20-80) were included in the study. Mean time from CD confirmation was 5.8±0.7 years (range 1-25). Exocrine pancreatic insufficiency (EPI) was diagnosed in four (4.4%) patients (one with mild EPI and three with severe EPI). MRI showed no morphological changes in any of the four patients. In all patients with EPI at least one serological nutritional marker was below the lower limit of normal. CONCLUSIONS EPI is present in a small number of patients with CD. EPI should be excluded in all patients with CD in the presence of overt malnutrition or in cases of persistent gastrointestinal symptoms despite a gluten-free diet. Measurement of a serum nutritional panel, regardless of the presence of clinical symptoms of EPI, can be of clinical importance. MRI should be performed to exclude any morphological change in the pancreas.

Abstract
BACKGROUND & AIMS We investigated whether risk for non-insulin-dependent diabetes mellitus (NIDDM) and metabolic syndrome are affected by celiac disease. We examined the prevalence of NIDDM and metabolic syndrome among adults with celiac disease, compared with matched controls. METHODS We assessed medical records of 840 patients with biopsy-proven celiac disease for diagnoses of NIDDM, hypertension, or hyperlipidemia; body mass index (BMI); lipid profile; and levels of glucose or glycosylated hemoglobin, to identify those with metabolic syndrome. Patients without celiac disease were matched for age, sex, and ethnicity (n = 840 controls). The prevalence of NIDDM and metabolic syndrome in the celiac disease cohort was compared with that of the controls and subjects included in the National Health and Nutrition Examination Survey. RESULTS Twenty-six patients with celiac disease (3.1%) had NIDDM compared with 81 controls (9.6%) (P < .0001). Similarly, the prevalence of metabolic syndrome was significantly lower among patients with celiac disease than controls (3.5% vs 12.7%; P < .0001). The mean BMI of patients with celiac disease was significantly lower than that of controls (24.7 vs 27.5; P < .0001). However, celiac disease was still associated with a lower risk of NIDDM, after controlling for BMI. CONCLUSIONS The prevalence of NIDDM and metabolic syndrome are lower among patients with celiac disease than in matched controls and the general population. These differences are not explained by differences in BMI. Studies are needed to determine the mechanisms by which celiac disease affects the risk for NIDDM and metabolic syndrome.

Abstract
Celiac disease or gluten sensitivity may initially present as one or more neurological signs and/or symptoms. On the other hand, it may be associated with or complicated by neurological manifestations. Neurological presentations are rare in children but as many as 36% of adult patients present with neurological changes. With severe malnutrition after progression of celiac disease, different vitamin deficiencies may develop. Such problems can in turn overlap with previous neurological abnormalities including ataxia, epilepsy, neuropathy, dementia, and cognitive disorders. In this study, we aimed to review the neurological aspects of celiac disease. Early diagnosis and treatment could prevent related disability in patients with celiac disease.

Abstract
BACKGROUND Autoimmunity is clearly linked with hematologic malignancies, but less is known about autoimmunity and alimentary tract cancer risk, despite the specific targeting of alimentary organs and tissues by several autoimmune diseases. The authors therefore conducted the first systematic evaluation of a broad range of specific autoimmune diseases and risk for subsequent alimentary tract cancer. METHODS On the basis of 4,501,578 US male veterans, the authors identified 96,277 men who developed alimentary tract cancer during up to 26.2 years of follow-up. By using Poisson regression methods, the authors calculated relative risks (RRs) and 95% confidence intervals. RESULTS A history of autoimmune disease with localized alimentary tract effects generally increased cancer risks in the organ(s) affected by the autoimmune disease, such as primary biliary cirrhosis and liver cancer (RR, 6.01; 95% confidence interval [CI], 4.76-7.57); pernicious anemia and stomach cancer (RR, 3.17; 95% CI, 2.47-4.07); and ulcerative colitis and small intestine, colon, and rectal cancers (RR, 2.53; 95% CI, 1.05-6.11; RR, 2.06; 95% CI, 1.70-2.48; and RR, 2.07; 95% CI, 1.62-2.64, respectively). In addition, a history of celiac disease, reactive arthritis (Reiter disease), and systemic sclerosis all were associated significantly with increased risk of esophageal cancer (RR, 1.86-2.86). Autoimmune diseases without localized alimentary tract effects generally were not associated with alimentary tract cancer risk, with the exception of decreased risk for multiple alimentary tract cancers associated with a history of multiple sclerosis. CONCLUSIONS These findings support the importance of localized inflammation in alimentary tract carcinogenesis. Future research is needed to confirm the findings and improve understanding of underlying mechanisms by which autoimmune diseases contribute to alimentary tract carcinogenesis.

Abstract
Dermatitis herpetiformis is a rare disease that should be considered the cutaneous expression of a gluten-sensitive enteropathy indistinguishable from celiac disease. Dermatitis herpetiformis is often misdiagnosed and to date no guidelines for the management of dermatitis herpetiformis have been published in Literature. The present guidelines have been prepared for dermatologists by the Group for Cutaneous Immunopathology of the Italian Society of Dermatology and Venereology. They reflect the best data available at the time of preparation and the clinical experience of the authors and the members of the Italian Group for Cutaneous Immunopathology. The diagnosis of dermatitis herpetiformis is established clinically, histologically, immunopathologically and serologically. A gluten-free diet (GFD) is the treatment of choice for patients with dermatitis herpetiformis. Dapsone and/or other drugs should be used during the period until the GFD is effective. In conclusion, the present guidelines provide evidence-based guidance for the diagnosis and treatment of dermatitis herpetiformis.

Abstract
Celiac disease is a gluten-dependent intestinal disorder that appears to be associated with several clinical conditions. Some involve the luminal mucosa of the stomach and intestinal tract and may, occasionally, complicate the course of celiac disease. Collagenous colitis has been associated with celiac disease and may lead to chronic diarrhea. Conversely, some of these clinical disorders that involve the luminal mucosa of the stomach and intestine may represent the initial clinical presentation of celiac disease. These disorders should be considered in patients with celiac disease who develop recurrent or refractory symptoms despite adherence to a strict gluten-free diet. Detection of collagenous disorders that affect the luminal mucosa of the stomach or intestinal tract may result in recognition of underlying celiac disease.

Abstract
Celiac disease may initially present as a neurological disorder. Alternatively, celiac disease may be complicated by neurological changes. With impaired nutrient absorption, different deficiency syndromes may occur and these may be manifested clinically with neurological changes. However, in patients with deficiency syndromes, extensive involvement of the small intestine with celiac disease is often evident. There are a number of reports of celiac disease associated with neuropathy, ataxia, dementia and seizure disorder. In these reports, there is no clear relationship with nutrient deficiency and a precise mechanism for the neurological changes has not been defined. A small number of patients have been reported to have responded to vitamin E administration, but most do not. In some, gluten antibodies have also been described, especially in those with ataxia, but a consistent response to a gluten-free diet has not been defined. Screening for celiac disease should be considered in patients with unexplained neurological disorders, including ataxia and dementia. Further studies are needed, however, to determine if a gluten-free diet will lead to improvement in the associated neurological disorder.

Abstract
There is an increased awareness that celiac disease may occur in the elderly although presentations with either diarrhea, weight loss or both may be less common causing delays in diagnosis for prolonged periods. Higher detection rates also seem evident owing to active case screening, largely through serodiagnostic measures. In some elderly patients who are genetically predisposed, it has been hypothesized that celiac disease might be precipitated late in life by an antigen, possibly from an infectious agent. As a result, peptide mimicry or other poorly-defined mechanisms may precipitate an autoimmune gluten-dependent clinical state. Although diarrhea and weight loss occur, only isolated iron deficiency anemia may be present at the time of initial diagnosis. In addition, the risk of other autoimmune disorders, particularly autoimmune thyroiditis, and bone disease, are increased. Osteopenia may also be associated with an increased risk of fractures. Finally, elderly celiacs have an increased risk of malignant intestinal disease, especially lymphoma.
