Guinea pig transglutaminase immunolinked assay does not predict coeliac disease in patients with chronic liver disease

BACKGROUND—It has been suggested that serological screening for coeliac disease (CD) should be performed in patients with chronic unexplained hypertransaminasaemia.
AIMS—To evaluate the specificity for CD diagnosis of serum IgA antitissue transglutaminase (tTG) determination in consecutive patients with chronic hypertransaminasaemia using the most widely utilised ELISA based on tTG from guinea pig as the antigen.
PATIENTS AND METHODS—We studied 98 patients with chronic hypertransaminasaemia, evaluated for the first time in a hepatology clinic. Serum anti-tTG and antiendomysial (EmA) assays were performed. Patients positive for EmA and/or anti-tTG were proposed for intestinal biopsy. Finally…

Steatocrit test: Normal range and physiological variations in infants

In order to define the normal values of steatocrit during the first 3 months of life and the normal correlation between fecal fat content and steatocrit values, 60 full-term healthy unweaned infants (30 bottle-fed, 15 breast-fed, and 15 mixed-fed) were studied. The steatocrit micromethod was performed in these babies at 7, 14, 21, 28, 45, and 90 days after birth. Steatorrhea often occurs during the first month and then decreases, as shown by the fall in the steatocrit curve from 7th to 28th day in our subjects; at 45 days, few babies have steatorrhea. The 90th percentile profile of steatocrit values shows a value of 25% at the first week of life and a value of 13% at the fourth week. After …

Prevalence of diabetes mellitus and impaired glucose tolerance in cystic fibrosis.

The aim of this study was to evaluate the prevalence of impaired glucose tolerance or diabetes mellitus in 99 patients (53 M, 46 F; mean age 10.5 +/- 6.9 years), with cystic fibrosis. Glucose tolerance was evaluated in all patients without overt diabetes using the oral glucose tolerance test (OGTT). Six patients showed a pathological OGTT and 2 patients had insulin-requiring diabetes mellitus. The mean age of the patients with impaired glucose tolerance was significantly higher than that of the subjects with normal glucose metabolism (p less than 0.0001). Patients with overt diabetes mellitus were the oldest subjects in the study group.

Diagnostic use of fructosamine assay in the control of type II diabetes mellitus.

In an attempt to evaluate the usefulness of fructosamine assay in monitoring type II diabetes, 142 diabetic patients were investigated. Fructosamine values were found to be higher in patients on insulin treatment than on oral hypoglycemic agents. In order to evaluate the metabolic control by using the correlated variations of F, Gm and HbAlc, the patients were subdivided into many control classes: mean values of fructosamine were higher in poorly controlled patients. Fructosamine however correlated better with glycemia in patients with recent variations in metabolic state than HbAlc. It was concluded that fructosamine is a good index for short-term metabolic control, and if used in an integ…

Non-Celiac Gluten Sensitivity: The New Frontier of Gluten Related Disorders

Non Celiac Gluten sensitivity (NCGS) was originally described in the 1980s and recently a “re-discovered” disorder characterized by intestinal and extra-intestinal symptoms related to the ingestion of gluten-containing food, in subjects that are not affected with either celiac disease (CD) or wheat allergy (WA). Although NCGS frequency is still unclear, epidemiological data have been generated that can help establishing the magnitude of the problem. Clinical studies further defined the identity of NCGS and its implications in human disease. An overlap between the irritable bowel syndrome (IBS) and NCGS has been detected, requiring even more stringent diagnostic criteria. Several studies sug…

Multiple food hypersensitivity as a cause of refractory chronic constipation in adults

Chronic constipation that is unresponsive to laxative treatment is a severe illness, but children unresponsive to laxatives have been successfully treated with an elimination diet. We report the first cases of refractory chronic constipation caused by food hypersensitivity in adults. Four patients with refractory constipation who were unresponsive to high doses of laxatives were put on an oligo-antigenic diet and underwent successive double-blind, placebo-controlled, food challenges (DBPFC). Routine laboratory tests, immunological assays, colonoscopy, esophago-gastroduodenoscopy and rectal and duodenal histology were performed. While on an elimination diet, bowel habits normalized in all pa…

Food allergy in irritable bowel syndrome: The case of non-celiac wheat sensitivity

Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders, having a prevalence of 12%-30% in the general population. Most patients with IBS attribute their symptoms to adverse food reactions. We review the role of diet in the pathogenesis of IBS and the importance of dietary factors in the management of these patients. The MEDLINE electronic database (1966 to Jan 2015) was searched using the following keywords: "food", "diet", "food allergy", "food hypersensitivity", "food intolerance", "IBS", "epidemiology", "pathogenesis", "pathophysiology", "diagnosis", "treatment".

Diagnosis of focal nodular hyperplasia. Role of imaging techniques.

Focal nodular hyperplasia (FNH) is a rare benign liver lesion which is difficult to differentiate from other benign liver pathologies and hepatocellular carcinoma. However, with appropriate new imaging techniques it is, at present, possible to diagnose this lesion with certainty thus avoiding invasive tests. Patient follow-up is also facilitated. It is often incidentally discovered during an abdominal ultrasound for other pathologies. Color power Doppler allows, in most cases, one to distinguish it from other focal liver lesions. However, in doubtful cases contrast-enhanced computed tomography and magnetic resonance imaging can help us to define the exact nature of the lesion. It is only oc…

Suspected Nonceliac Gluten Sensitivity Confirmed in Few Patients After Gluten Challenge in Double-Blind, Placebo-Controlled Trials

A double-blind, placebo-controlled, gluten challenge has been proposed to confirm a diagnosis of non-celiac gluten sensitivity (NCGS) in patients without celiac disease who respond to a gluten-free diet. To determine the accuracy of this approach, we analyzed data from 10 double-blind, placebo-controlled, gluten challenge trials, comprising 1312 adults. The studies varied in the duration of the challenge (ranging from 1 day to 6 weeks), daily doses for the gluten challenge (ranging from 2 g to 52 g; 3 studies administered less than 8 g/day), and composition of the placebo (gluten-free products, xylose, whey protein, rice, or corn starch containing fermentable carbohydrates).

The production of the oral mucosa of antiendomysial and anti-tissue-transglutaminase antibodies in patients with celiac disease: a review.

Celiac disease (CD) is a lifelong, T cell—mediated enteropathy, triggered by the ingestion of gluten and related prolamins in genetically susceptible subjects, resulting in minor intestinal mucosal injury, including villous atrophy with crypt hyperplasia and intraepithelial lymphocytosis, and subsequent nutrient malabsorption. Although serological tests for antiendomysial (EMA) and anti—tissue transglutaminase (anti-tTG) autoantibodies are used to screen and follow up on patients with CD, diagnostic confirmation is still based on the histological examination of the small intestinal mucosa. Although the small intestinal mucosa is the main site of the gut involved in CD, other mucosal surface…

Role of FODMAPs in Patients With Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a condition characterized by abdominal pain, bloating, flatus, and altered bowel habits. The role of dietary components in inducing IBS symptoms is difficult to explore. To date, foods are not considered a cause but rather symptom-triggering factors. Particular interest has been given to the so-called FODMAPs (fermentable oligo-, di-, and monosaccharides and polyols). We aimed to summarize the evidence from the most common approaches to manage suspected food intolerance in IBS, with a particular interest in the role of FODMAPs and the effects of a low FODMAP diet.

Epidemiology and pathogenesis of celiac disease and non-celiac gluten (wheat) sensitivity

Abstract While in the past, celiac disease (CD) was considered the only clinical entity caused by the ingestion of gluten-containing grains, now there is evidence that a spectrum of gluten-related disorders, including also wheat allergy and non-celiac gluten (wheat) sensitivity (NCGS/NCWS), exists. The prevalence of gluten-related disorders is rising, and increasing numbers of individuals are empirically trying a gluten-free diet for a variety of signs and symptoms. CD is a gluten-induced immune-mediated enteropathy characterized by a specific genetic genotype [human leukocyte antigen (HLA)-DQ2 and HLA-DQ8 genes] and autoantibodies (antitissue transglutaminase and antiendomysial).

The Risk of Contracting COVID-19 Is Not Increased in Patients With Celiac Disease

The World Health Organization declared coronavirus disease-2019 (COVID-19) a global pandemic in March 2020. Since then, there are more than 34 million cases of COVID-19 leading to more than 1 million deaths worldwide. Numerous studies suggest that celiac disease (CeD), a chronic immune-mediated gastrointestinal condition triggered by gluten, is associated with an increased risk of respiratory infections.(1-3) However, how it relates to the risk of COVID-19 is unknown. To address this gap, we conducted a cross-sectional study to evaluate whether patients with self-reported CeD are at an increased risk of contracting COVID-19.

Review article: intestinal lymphoid nodular hyperplasia in children - the relationship to food hypersensitivity.

SummaryBackground Lymphoid aggregates are normally found throughout the small and large intestine. Known as lymphoid nodular hyperplasia (LNH), these aggregates are observed especially in young children and are not associated with clinical symptoms being considered ‘physiological’. In children presenting with gastrointestinal symptoms the number and size of the lymphoid follicles are increased. Patients suffering from gastrointestinal symptoms (i.e. recurrent abdominal pain) should systematically undergo gastroduodenoscopy and colonoscopy. With these indications LNH, especially of the upper but also of the lower gastrointestinal tract has been diagnosed, and in some children it may reflect …

The old and new tests for celiac disease: which is the best test combination to diagnose celiac disease in pediatric patients?

BACKGROUND In the diagnosis of celiac disease (CD), serum assays for anti-endomysium (EMA) and anti-transglutaminase (anti-tTG) antibodies have excellent diagnostic accuracy. However, these assays are less sensitive in young pediatric patients. Recently, a new ELISA test using deamidated gliadin peptides (DGP) as antigen has proved to be very sensitive and specific even in pediatric patients. In addition, anti-actin IgA antibodies (AAA) is another test that can be used in CD patients because antibody concentrations correlate with the degree of villous atrophy. This study evaluated the clinical accuracy of anti-tTG, EMA, AGA, anti-DGP and AAA and the effectiveness of these in different combi…

A difficult diagnosis of coeliac disease: Repeat duodenal histology increases diagnostic yield in patients with concomitant causes of villous atrophy

Abstract Villous atrophy in absence of coeliac disease (CD)-specific antibodies represents a diagnostic dilemma. We report a case of a woman with anaemia, weight loss and diarrhoea with an initial diagnosis of seronegative CD and a histological documented villous atrophy who did not improve on gluten-free diet due to the concomitant presence of common variable immunodeficiency (CVID) and Giardia lamblia infection. This case report confirms that CD diagnosis in CVID patients is difficult; the combination of anti-endomysial antibodies (EmA-IgA), anti-tissue transglutaminase antibodies (tTG-IgAb) antibodies and total IgA is obligatory in basic diagnostic of CD but in CVID are negative.

Non-celiac wheat sensitivity as an allergic condition: personal experience and narrative review.

Non-celiac wheat sensitivity (NCWS) is a newly described clinical entity characterized by symptoms, which can involve the gastrointestinal tract, the nervous system, the skin, and other organs. There is little data on the pathogenesis of NCWS and it is probable that different pathogenic mechanisms are involved in the different clinical manifestations of the disease. The only common denominator of NCWS "syndrome" is wheat consumption: the symptoms disappear on exclusion of wheat from the diet, and reappear on wheat consumption. The objective of this study was to review our prior data regarding NCWS and to review relevant medical literature regarding NCWS, with particular attention to the hyp…

Pneumococcal vaccination in celiac disease

Introduction: Celiac disease (CD) is an immune-mediated disorder associated with gluten exposure in genetically predisposed subjects. Areas covered: Infectious disease is one of the causes of morbidity and mortality in CD patients. Invasive streptococcus pneumoniae (pneumococcus) is a particularly dangerous morbid condition in both the general population and celiac patients. Pneumococcal vaccination is the most effective means for its prevention. Expert opinion: In CD, evaluation of spleen function should be useful to select patients who may benefit from vaccination to reduce the risk of pneumococcal disease. Different strategies could be employed: physicians could search for signs of hypos…

Context: Lipase maturation factor 1 (LMF1) gene is a novel candidate gene in severe hypertriglyceridemia. Lmf1 is involved in the maturation of lipoprotein lipase (LPL) and hepatic lipase in endoplasmic reticulum. To date only one patient with severe hypertriglyceridemia and related disorders was found to be homozygous for a nonsense mutation in LMF1 gene (Y439X).Objective: The objective of the study was to investigate LMF1 gene in hypertriglyceridemic patients in whom mutations in LPL, APOC2, and APOA5 genes had been excluded.Results: The resequencing of LMF1 gene led to the discovery of a novel homozygous nonsense mutation in one patient with severe hypertriglyceridemia and recurrent epis…

A Cytologic Assay for Diagnosis of Food Hypersensitivity in Patients With Irritable Bowel Syndrome

BACKGROUND &amp; AIMS: A percentage of patients with symptoms of irritable bowel syndrome (IBS) suffer from food hypersensitivity (FH) and improve on a food-elimination diet. No assays have satisfactory levels of sensitivity for identifying patients with FH. We evaluated the efficacy of an in vitro basophil activation assay in the diagnosis of FH in IBS-like patients. METHODS: Blood samples were collected from 120 consecutive patients diagnosed with IBS according to Rome II criteria. We analyzed in vitro activation of basophils by food allergens (based on levels of CD63 expression), as well as total and food-specific immunoglobulin (Ig)E levels in serum. Effects of elimination diets and dou…

Nonceliac wheat sensitivity in the context of multiple food hypersensitivity: new data from confocal endomicroscopy.

Dear Editor, We enjoyed reading the article by Fritscher-Ravens et al who showed, by confocal endomicroscopy, that candidate food antigens caused immediate duodenal mucosa damage in irritable bowel syndrome (IBS) patients with a prolonged clinical history of symptoms after meals. Their in vivo data add evidence to the relationship between IBS and food allergy and seem to reinforce our hypothesis that a percentage of “nonceliac wheat sensitive” (NCWS) -patients with an IBS-like clinical presentation could suffer from non-immunoglobulin E-mediated wheat allergy. However, we would suggest that the very high percentage of positive confocal laser endomicroscopy patients (CLE) -22 out of 36- foun…

Pancreatic enzymes in chronic renal failure and transplant patients.

The aim of the present study was to determine the frequency and degree of elevated serum levels of Total Amylase (TA), Pancreatic Amylase (PA), and Lipase (L) activity in patients with chronic renal failure (CRF) on conservative therapy; CRF on periodical hemodialysis (HD); in renal transplant (RT) and in a control Group (C). Mean values were significantly higher in all groups than Group C for TA (p < 0.005), PA (p < 0.0001) and L (p < 0.0001). A statistically significant correlation was found between TA and L vs creatininemia values in CRF patients, but only up to a certain level (creatininemia < 6 mg %) (p < 0.03 and p < 0.05), above which there was no correlation.

From Food Map to FODMAP in Irritable Bowel Sindrome.

Irritable bowel syndrome (IBS) is one of the most common gastrointestinal diseases in the general population, with a prevalence ranging from 12 % to 30 %, mainly affecting younger patients (i.e., <50 years of age) and women [1]. As in other chronic functional gastrointestinal disorders, abdominal discomfort or pain, abnormal bowel habits, and often bloating and abdominal distension are the main clinical features. Their diagnosis is based on symptom patterns (i.e., the Rome III criteria), which also allow categorization in diarrhea-predominant (D-IBS), constipation-predominant (C-IBS), mixed diarrhea and constipation (M-IBS), and unclassified (U-IBS) IBS [2]. Symptom severity ranges from tol…

Diagnosis of chronic anaemia in gastrointestinal disorders: a guideline by the Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) and the Italian Society of Paediatric Gastroenterology Hepatology and Nutrition (SIGENP)

Anaemia is a common pathologic condition, present in almost 5% of the adult population. Iron deficiency is the most common cause; other mechanisms can be involved, making anaemia a multi-factorial disorder in most cases. Anaemia being a frequent manifestation in the diseases of the gastrointestinal tract, patients are often referred to gastroenterologists. Furthermore, upper and lower endoscopy and enteroscopy are pivotal to the diagnostic roadmap of anaemia. In spite of its relevance in the daily clinical practice, there is a limited number of gastroenterological guidelines dedicated to the diagnosis of anaemia. For this reason, the Italian Association of Hospital Gastroenterologists and E…

Chronic Urticaria as a presenting symptom of Crohn’s disease.

Clinical presentation of Crohn’s disease (CD) may be variable according to the location and the intensity of the inflammation. Some patients may have atypical symptoms which could delay the diagnosis. We report the first case of chronic urticaria related to a subclinical, complicated CD. Although the pathologic mechanism of this association was unclear in our patient, this case suggests that in patients with unexplained chronic urticaria it is opportune to investigate for a possible CD, even if there are no or few specific symptoms of intestinal inflammatory disease.

Osteodystrophy in chronic liver diseases

Osteoporosis and osteomalacia are, to date, among the most common metabolic diseases in the world. Lately, an association between metabolic bone diseases and chronic liver disease has been increasingly reported, inducing many authors to create a new nosographic entity known as 'hepatic osteodystrophy.' The importance of such a condition is further increased by the morbidity of these two diseases, which greatly reduce the quality of life because of frequent fractures, especially vertebral and femoral neck ones. For this reason, early identification of high-risk patients should be routinely performed by measuring bone mass density. The explanation for the association between bone diseases and…

TNF-α, IL-17, and IL-22 production in the rectal mucosa of nonceliac wheat sensitivity patients: role of adaptive immunity.

In recent years, a new gluten- or wheat-related disease has emerged, a condition labeled "nonceliac gluten sensitivity" (NCGS) or "nonceliac wheat sensitivity" (NCWS). NCWS pathogenesis is still uncertain and attributed to very different mechanisms. We aimed to study the different T-lymphocyte subsets in the rectal mucosa of NCWS patients to demonstrate the possible contribution of adaptative immune response. Twelve patients (11 women, 1 man, age range 23-61 yr, median 32 yr) with a definitive diagnosis of NCWS were recruited at random for the present study. They underwent rectal endoscopy with multiple mucosal biopsies at the end of a double-blind placebo-controlled (DBPC) wheat challenge …

Diagnosis of Non-Celiac Gluten Sensitivity (NCGS): The Salerno Experts’ Criteria

Non-Celiac Gluten Sensitivity (NCGS) is a syndrome characterized by intestinal and extra-intestinal symptoms related to the ingestion of gluten-containing food, in subjects that are not affected by either celiac disease or wheat allergy. Given the lack of a NCGS biomarker, there is the need for standardizing the procedure leading to the diagnosis confirmation. In this paper we report experts' recommendations on how the diagnostic protocol should be performed for the confirmation of NCGS. A full diagnostic procedure should assess the clinical response to the gluten-free diet (GFD) and measure the effect of a gluten challenge after a period of treatment with the GFD. The clinical evaluation i…

Clinical case and short review of extreme short bowel syndrome: an update 21 years after

Short bowel syndrome refers to the malabsorptive state caused by loss of significant portions of the small intestine, whose clinical framework is characterized by malnutrition, diarrhea, dehydration, weight loss, and low-weight-related symptoms/signs. These clinical conditions seem to be related to the length of resection. Twenty-one years ago we reported the clinical case of an infant, who underwent a massive resection of the loops of the small intestine, of the cecum and of part of the ascending colon, due to intestinal malrotation with volvulus. The residual small intestine measured just 11 cm and consisted of the duodenum and a small part of jejunum, in the absence of the ileocecal valv…

One hundred and seven patients with histologically proven chronic hepatitis C were enrolled during a period of three years and randomly divided into three groups, to receive (a) leukocyte-interferon-alpha, 6 MU three times a week for 4 months, followed by 3 MU three times a week for 8 months (Group I); (b) recombinant-IFN-alpha-2a, with the same schedule (Group II); and (c) lymphoblastoid-IFN-alpha-N1, with the same schedule (Group III). All patients were followed-up for 6 months to evaluate the long-term response. The 'C…

Intolerance of Cow's Milk and Chronic Constipation in Children

Background Chronic diarrhea is the most common gastrointestinal symptom of intolerance of cow's milk among children. On the basis of a prior open study, we hypothesized that intolerance of cow's milk can also cause severe perianal lesions with pain on defecation and consequent constipation in young children. Methods We performed a double-blind, crossover study comparing cow's milk with soy milk in 65 children (age range, 11 to 72 months) with chronic constipation (defined as having one bowel movement every 3 to 15 days). All had been referred to a pediatric gastroenterology clinic and had previously been treated with laxatives without success; 49 had anal fissures and perianal erythema or e…

Concomitant inflammatory pseudotumor of the liver and spleen

We report the case of a 53-year-old man with inflammatory pseudotumor (IPT) of the liver and spleen. This concomitant association has rarely been reported. The patient presented with a hypoechoic mass in the liver and a clinical picture of recurrent sepsis; hematochemical exams and imaging data were nonspecific. Antibiotic therapy improved the clinical course, but did not resolve it definitively. After 50 days of therapy, as the hepatic mass decreased a similar lesion appeared in the spleen. The final diagnosis was made on splenectomy and an intra-operative biopsy of the residual liver lesion. The diagnostic problems encountered in this very rare association of IPT of the liver and spleen w…

Pancreatic insufficiency in celiac disease is not dependent on nutritional status

To determine the relationship between pancreatic secretory capacity and nutritional status in celiac patients, we studied 52 patients with celiac disease (24 males, 28 females; age range 6-36 months) and 30 healthy control subjects (14 males, 16 females; age range 6-42 months). A secretin-cerulein test was performed on all patients, and levels of serum albumin and plasma fibronectin were assayed. In addition, weight/height ratios were calculated in the celiacs, who were then divided into three groups on this basis, as follows: celiacs with weight/height ratioor = 3rd percentile; those with weight/height ratio between the 4th and 10th percentiles; and those with weight/height ratio10th perce…

Plasma calprotectin levels in patients suffering from acute pancreatitis

Calprotectin (Cal) concentration is elevated in acute inflammatory reactions and its increase in the plasma suggests a diagnostic potential for Cal assay. This study aimed (a) to evaluate the Cal plasma levels in patients suffering from acute pancreatitis (AP) and (b) to assess whether early assay of Cal plasma levels can be helpful in assessment of the severity of AP. Forty-six consecutive patients, median age 45 years, suffering from a first attack of AP were recruited at two medical centers. Data collected on admission included age, sex, delay between pain onset and admission, and Glasgow score. A severe outcome was defined according to the Atlanta criteria. AP was defined as edematous o…

The metabolic syndrome predicts cardiovascular events in subjects with normal fasting glucose: results of a 15 years follow-up in a Mediterranean population.

The aim of this study was to evaluate the cardiovascular (CV) risk due to the metabolic syndrome in a 15-year prospective study of a Sicilian population. In the Mediterranean area obesity is highly prevalent, but epidemiological data on the metabolic syndrome are limited. Methods and results: Among the 1351 subjects enrolled in the “Ventimiglia di Sicilia” epidemiological project, we selected 687 subjects between 35 and 75 years of age; baseline parameters were assessed and subjects have been followed for 15 years recording CV events, total and cardiovascular mortality. The metabolic syndrome was defined according to both the Adult Treatment Panel III and the International Diabetes Federati…
