  • 'Food Sensitivities, Wheat-Related Disorders and Cardiovascular Disease', Chapter 3 of Cardiovascular Medicine: An Integrative, Functional and Metabolic Medicine Approach,

    Wolters Kluwers 2019

    Arguably, one of the most researched conditions diagnosed from an Adverse Reaction to Food (ARF) is Celiac Disease-an autoimmune reaction to wheat. Celiac disease has traditionally been clinically considered and then investigated with patients presenting with gastrointestinal (GI) symptoms. However, for every adverse reaction to wheat presenting with GI symptoms, there are 8 presenting without GI symptoms. Thus, dependence on GI complaints as a prerequisite in considering an adverse reaction to…

    Arguably, one of the most researched conditions diagnosed from an Adverse Reaction to Food (ARF) is Celiac Disease-an autoimmune reaction to wheat. Celiac disease has traditionally been clinically considered and then investigated with patients presenting with gastrointestinal (GI) symptoms. However, for every adverse reaction to wheat presenting with GI symptoms, there are 8 presenting without GI symptoms. Thus, dependence on GI complaints as a prerequisite in considering an adverse reaction to wheat, will allow a majority to escape diagnosis. This is a critical point of recognition for the Clinician when considering an association of wheat related disorders (WRD) and cardiovascular health.
    This Chapter will summarize the explosion in studies in the last 15 years of the contribution ofa Wheat Related Disorder to CVD.

  • 'Navigating the Gluten-Free Boom: The Dark Side of Gluten Free Diet'

    Frontiers in Pediatrics

    In gluten dependent conditions the gluten free diet is the cornerstone of therapy, decreasing disease activity, improving health and quality of life and treating or preventing the associated complications. Gluten withdrawal implies strict and lifelong elimination not only of wheat, barley, rye, and wheat-contaminated oats, but also of numerous non-nutritional products where components of wheat are often added. Due to multiple reasons the diet is difficult to follow and the long-term adherence…

    In gluten dependent conditions the gluten free diet is the cornerstone of therapy, decreasing disease activity, improving health and quality of life and treating or preventing the associated complications. Gluten withdrawal implies strict and lifelong elimination not only of wheat, barley, rye, and wheat-contaminated oats, but also of numerous non-nutritional products where components of wheat are often added. Due to multiple reasons the diet is difficult to follow and the long-term adherence is decreased with time. The present review summarizes the dark side of gluten restriction where nutritional deficiencies, toxicity, morbidity, mortality, and mental health problems are reported. The aim being to increase awareness, avoid, detect and treat the side effects and to promote a healthier nutrition, for the patient's benefits.

  • Review of Three Pediatric Wheat-Related Disorder Cases with Disparate Clinical Manifestations

    HSOA Journal of Gastroenterology & Hepatology Research

    The consumption of wheat-based products is high in most Western countries (e.g. Europe, United States) and is increasing in Eastern countries as a consequence of a shift toward a Western lifestyle. Historically, Wheat-Related Disorders (WRD) referred only to wheat allergy and celiac disease. In recent years, a growing number of subjects worldwide have reported intestinal and extraintestinal symptoms, without the diagnostic features of celiac disease or wheat allergy. In these subjects, symptoms…

    The consumption of wheat-based products is high in most Western countries (e.g. Europe, United States) and is increasing in Eastern countries as a consequence of a shift toward a Western lifestyle. Historically, Wheat-Related Disorders (WRD) referred only to wheat allergy and celiac disease. In recent years, a growing number of subjects worldwide have reported intestinal and extraintestinal symptoms, without the diagnostic features of celiac disease or wheat allergy. In these subjects, symptoms of a wheat-related disorder may originate from non-celiac gluten sensitivity, the non-gluten antibody target protein serpins, purinins, α-amylase/protease inhibitors, globulins, farinins, wheat exorphin sensitivity, wheat germ agglutinin sensitivity, wheat amylase-trypsin inhibitor sensitivity, and/or FODMAP (fermentable oligo-, di-, mono- saccharides and polyols) sensitivity. This article reviews the pertinent literature and presents three pediatric cases of wheat-related disorders that present with varied clinical presentations: liver failure, type 1 diabetes mellitus and a conjunctival tumor believed to be Kaposi’s sarcoma. All conditions responded rapidly to a wheat-free diet. A wheat-related disorder (with or without celiac disease) may affect any organ or system including cardiovascular disease, neurological diseases, connective tissue diseases, allergies, inflammatory bowel disease, nephritis and others. While there is increasing awareness that wheat-related disorders can manifest with extraintestinal symptoms, clinicians still rely too heavily on the presence of gastrointestinal symptoms to suspect a wheat-related disorder. These three cases showed wheat-related pathogenesis affecting diverse organs, such as the liver, pancreas, or eye, without marked gastrointestinal symptoms. Therefore, in patients with unexplained symptoms, who do not improve with standard therapies, it may be prudent to screen for serological indicators of a WRD.

  • Reproductive Disorders in Celiac Disease

    Journal of Practical Gastroenterology

    Despite re-classification of celiac disease as a rare disease of childhood to a common dis- ease affecting men, women and children at any age, most of the three million estimated sufferers remain undiagnosed. Proper education concerning the various symptoms and manifestations of the disease is necessary to increase prompt and accurate diagnosis.

    Despite re-classification of celiac disease as a rare disease of childhood to a common dis- ease affecting men, women and children at any age, most of the three million estimated sufferers remain undiagnosed. Proper education concerning the various symptoms and manifestations of the disease is necessary to increase prompt and accurate diagnosis. Celiac disease’s potentially negative effect on reproductive health is among the most pressing matters associated with advancing awareness. Men and women with unex- plained infertility, women with recurrent abortions, intrauterine growth retardation, low birth weight babies and menstrual disorders are rarely screened for celiac disease despite scientific studies that indicate a correlation. In the following article, we will examine the evidence for these occurrences in a literature review, examine potential the- ories about their cause, and discuss the need for additional research and the addition of a celiac testing to the differential diagnosis in women with reproductive health problems.

  • THE IMMUNOLOGY OF GLUTEN SENSITIVITY BEYOND THE INTESTINAL TRACT

    European Journal of Inflammation

    Celiac disease and gluten-sensitive enteropathy are terms that have been used to refer to a disease process affecting the small bowel. However, evidence has been accumulated in literature demonstrating that gluten sensitivity or celiac disease can exist even in the absence of enteropathy, but affecting many organs. Based on overwhelming evidence, immunological pathogenesis has been demonstrated in the joint, the heart, thyroid, bone, and, in particular, the brain cerebellum and neuronal…

    Celiac disease and gluten-sensitive enteropathy are terms that have been used to refer to a disease process affecting the small bowel. However, evidence has been accumulated in literature demonstrating that gluten sensitivity or celiac disease can exist even in the absence of enteropathy, but affecting many organs. Based on overwhelming evidence, immunological pathogenesis has been demonstrated in the joint, the heart, thyroid, bone, and, in particular, the brain cerebellum and neuronal synapsin I. When blood samples of patients with celiac disease are tested against gliadin and different tissue antigens, in addition to gliadin antibody, a significant percentage of them exhibit elevation in antibodies against transglutaminase, heat shock protein, collagen, thyroid, myosin, endothelial cell, bone antigen (transglutaminase), myelin basic protein, cerebellar and synapsin. This elevation of autoantibodies in patients with celiac disease may result in neuroimmune disorders. In fact, in comparison to the general population, the incidence of various autoimmune disorders, including gluten ataxia, is increased up to 30-fold in patients with celiac disease. Therefore, immune evaluation of patients with gluten sensitivity or celiac disease, in addition to gliadin and transglutaminase, should include antibody measurement against thyroglobulin, thyroid peroxidase, heat shock protein, bone transglutaminase, myelin basic protein, cerebellar peptide and synapsin. This novel laboratory approach to gluten sensitivity and autoimmunity may enable clinicians to detect markers of autoimmune diseases. Early identification of gluten sensitive and celiac disease patients and implementation of a gluten-free diet may result in significant improvement and control of associated diseases.

  • THE IMMUNOLOGY OF IMMEDIATE AND DELAYED HYPERSENSITIVITY REACTION TO GLUTEN

    EUROPEAN JOURNAL OF INFLAMMATION

    The immunology of gluten hypersensitivity and celiac disease has been pursued with significant interest in the past 20 years. For the prevention of systemic diseases, most pathogens that gain entry into our bodies must be met with an effective immune response, yet in the gastrointestinal tract it is equally important that commensal bacteria and a diverse collection of dietary proteins and peptides be recognized without eliciting an active immune response or constant activation of the…

    The immunology of gluten hypersensitivity and celiac disease has been pursued with significant interest in the past 20 years. For the prevention of systemic diseases, most pathogens that gain entry into our bodies must be met with an effective immune response, yet in the gastrointestinal tract it is equally important that commensal bacteria and a diverse collection of dietary proteins and peptides be recognized without eliciting an active immune response or constant activation of the inflammatory pathway. This phenomenon of hyporesponsiveness to food antigens is known as oral tolerance. This oral tolerance to dietary antigens is maintained by three different mechanisms: anergy, cell deletion and immune suppression. However, in the presence of mechanical/chemical stressors and infections, this tolerance may break down, and gut associated lymphoid tissues (GALT) will react to different luminal antigens. The reaction of GALT to these antigens may lead to the production of pro-inflammatory cytokines, opening of tight junctions, entry of undigested antigens into the circulation, and the subsequent production of IgA, IgG, IgM and IgE antibodies in blood and secretory components. Like any other food hypersensitivity reaction, gluten sensitivity can be divided into immediate and delayed hypersensitivities. In this review an attempt is made first to differentiate immediate hypersensitivity to gliadin, mediated by IgE, from delayed hypersensitivity, which is mediated by IgA and IgG. Furthermore, we attempt to differentiate between gluten hypersensitivity with enteropathy (celiac disease) and gluten hypersensitivity without enteropathy.

  • Immune Responses to Dietary Proteins, Gliadin and Cerebellar Peptides in Children with Autism

    Nutritional Neurosciences

    The mechanisms behind autoimmune reaction to nervous system antigens in autism are not understood. We assessed the reactivity of sera from 50 autism patients and 50 healthy controls to specific peptides from gliadin and the cerebellum. A significant percentage of autism patients showed elevations in antibodies against gliadin and cerebellar peptides simultaneously. For examining cross-reaction between dietary proteins and cerebellar antigens, antibodies were prepared in rabbits, and binding of…

    The mechanisms behind autoimmune reaction to nervous system antigens in autism are not understood. We assessed the reactivity of sera from 50 autism patients and 50 healthy controls to specific peptides from gliadin and the cerebellum. A significant percentage of autism patients showed elevations in antibodies against gliadin and cerebellar peptides simultaneously. For examining cross-reaction between dietary proteins and cerebellar antigens, antibodies were prepared in rabbits, and binding of rabbit anti-gliadin, anti-cerebellar peptides, anti-MBP, anti-milk, anti-egg, anti-soy and anti-corn to either gliadin- or cerebellar-antigen-coated wells was measured. In comparison to anti-gliadin peptide binding to gliadin peptide at 100%, the reaction of anti-cerebellar peptide to gliadin peptide was 22%, whereas the binding of anti-myelin basic protein (MBP), anti-milk, anti-egg and anti-soy to gliadin was less than 10%. Further examination of rabbit anti-gliadin (EQVPLVQQ) and anti-cerebellar (EDVPLLED) 8 amino acid (AA) peptides with human serum albumin (HSA) and an unrelated peptide showed no binding, but the reaction of these antibodies with both the cerebellar and gliadin peptides was greater than 60%. This cross-reaction was further confirmed by DOT-immunoblot and inhibition studies. We conclude that a subgroup of patients with autism produce antibodies against Purkinje cells and gliadin peptides, which may be responsible for some of the neurological symptoms in autism.
