Celiac sprue

Emerging evidence has shed light on non-celiac causes of enteropathy in recent years, presenting a diagnostic challenge for clinicians. This study discusses the diagnostic challenges related to non-celiac enteropathy, specifically focusing on olmesartan-induced enteropathy (OIE). A 73-year-old lady presented to the emergency department with a six-month history of watery diarrhea exacerbated by food intake and significant weight loss. The patient at admission was found to be dehydrated with severe hypokalemia and hypocalcemia...

BACKGROUND: Previous randomized controlled trials (RCTs) suggested that gut microbiota-based therapies may be effective in treating autoimmune diseases, but a systematic summary is lacking. METHODS: Pubmed, EMbase, Sinomed, and other databases were searched for RCTs related to the treatment of autoimmune diseases with probiotics from inception to June 2022. RevMan 5.4 software was used for meta-analysis after 2 investigators independently screened literature, extracted data, and assessed the risk of bias of included studies...

In India, the COVID-19 vaccination for adolescents aged 15-17 years has been started since January 2022. Gluten enteropathy, also known as celiac or nontropical sprue, can arise as an autoimmune disease of the small intestines. We report a 15-year-old female with a history of allergy to gluten-containing products who came for the first dose of the COVID-19 vaccination to adult vaccination OPD at All India Institute of Medical Sciences, Jodhpur. After taking a detailed history, she had an allergy to gluten-containing products for five years...

OBJECTIVES: The aim of the study was to assess long-term health-related quality of life (HRQoL) in children and adolescents with coeliac disease (CD), and their parents. METHODS: We re-evaluated prospectively the HRQoL and clinical characteristics of 80 families, assessed 5 years earlier, using a disease-specific questionnaire, the CD Dutch Questionnaire (CDDUX), and a generic questionnaire, the Paediatric Quality of Life Inventory (PedsQL). RESULTS: After a 10-year follow-up, there was no significant change in the total CDDUX and PedsQL scores in children and their parents when compared to the evaluation conducted 5 years earlier...

Celiac disease is an autoimmune disorder characterized by a broad spectrum of histological damage to the intestinal mucosa. Comprehension and understanding of the association between anti-tissue transglutaminase (anti-tTG) antibody levels and the histological severity of celiac disease are not well established, prompting the need for meta-analysis. This study aims to offer insights into the diagnostic abilities of anti-tTG antibody levels in determining the histological severity of celiac disease by providing quantitative evidence based on a diverse range of studies...

BACKGROUND AND AIM: Celiac disease (CeD) is mainly reported from the northern and western parts of India. In central India, it is believed to be a disease of children, with limited data among adults diagnosed for the first time after the age of 18 years. Hence, we aimed to describe CeD's clinical and demographic features among adults and children/adolescents in central India. METHODS: This is a retrospective analysis of a prospectively maintained database of all patients diagnosed for CeD from 2010 to 2019...

BACKGROUND: The diagnosis of celiac disease (CD) is based on positive IgA autoantibodies to tissue transglutaminase (TTG IgA) and confirmatory histopathology demonstrating duodenal villus atrophy (VA). Diagnostic challenges can occur when VA is found on duodenal biopsies in patients without prior CD serologies. AIMS: To characterize the predictors of CD seropositivity in patients with VA on biopsy without prior CD serologies. METHODS: We performed a retrospective cohort study of patients found to have duodenal VA on histopathology from 2010 to 2020 who did not have prior CD serologies measured and who had them checked after their biopsy...

PURPOSE OF REVIEW: The incidence of celiac disease (CD) has increased over the last decades in part due to better disease awareness. Small bowel ultrasound (sb US) enables dynamic assessment of the bowel; although this topic has been addressed, the use of sb US in the diagnosis and in the follow-up of CD patients is limited to a few specialized tertiary referral centers. Herein, we aimed at summarizing the available literature on this topic to better define the potential clinical implications of sb US in CD, also through a comparison with other available diagnostic techniques...

BACKGROUND: The purpose of this study was to understand the experiences of primary caretakers (PCTs) with a child diagnosed with celiac disease (CeD). There is paucity of research in understanding the experiences of PCTs of children with CeD in India. METHODS: Purposive sampling was used to select PCTs of CeD-affected children from a tertiary hospital in New Delhi. Ten PCTs took part in the investigation. To gather the data, semi-structured interviews were held with participants...

Olmesartan is a commonly used antihypertensive medication belonging to the class of angiotensin II receptor blockers. Though generally well-tolerated, olmesartan can rarely cause olmesartan-associated enteropathy (OAE) with non-bloody diarrhea, weight loss, abdominal pain, and vomiting. Patients may develop enteropathy months to years after drug initiation. In severe cases, patients may develop complications that require hospitalization. Diagnosis is often delayed due to unfamiliarity of OAE, nonspecific presenting symptoms, and normal-appearing gross endoscopic findings...

Almost a half-century ago, an unusual and distinct form of colitis was first recognized, collagenous colitis, characterized by sub-epithelial trichrome-positive deposits having the ultrastructural features of collagen. Later, other reports documented more extensive collagenous dis-ease in these patients, sometimes in the stomach and small bowel, a close linkage with other forms of microscopic colitis and its association with celiac and other immune-mediated diseases. Moreover, emerging genetic methods permitted large studies of collagenous colitis to complement these intriguing clinical and pathological studies...

Prolyl endopeptidases from Sphingomonas capsulata (SC PEP) has attracted much attention as promising oral therapy candidate for celiac sprue, however, its low stability in the gastric environment leads to unsatisfactory clinical results. Therefore, improving its stability against pepsin digestion at low pH is crucial for clinical applications, but challenging. In this study, machine learning and physical parameter model were combined to design SC PEP mutants. After iterations, 20 mutants had higher hydrolysis activity in stomach environment, which was up to 14...

Patients with olmesartan-induced enteropathy, a rare illness, frequently endure prolonged diarrhea and weight loss with no apparent cause. Because this adverse event's clinical and histological characteristics mimic those of other small intestine illnesses, it can be challenging to recognize it in a timely manner. We report a case of olmesartan-induced enteropathy in a 58-year-old male who had been on olmesartan for several years. Recently, during his travel to Greece, he developed diarrhea lasting several weeks...

Celiac-like disease and celiac sprue associated with widespread use of mycophenolic acid are among the most frequent complications of renal transplant. Most cases have been observed in patients receiving mycophenolate mofetil; however, there have been rare instance after administration of enteric-coated mycophenolate sodium. Here, we describe 4 renal transplant recipients with celiac-like duodenopathy that occurred in association with enteric-coated mycophenolate sodium treatment in a time period of 14 to 19 years after living donor kidney transplant...

Immunoproliferative small intestinal disease (IPSID) is an uncommon disease of the small intestine. There is a similarity in the clinical presentations of enteropathic diseases, including celiac disease, tropical sprue, IPSID, and Whipple's disease. A differentiation between them is based on the use of a highly specific serological test for celiac disease and specific histological characteristics. We found that IgA-anti-tissue transglutaminase antibody (IgA-tTG Ab) is falsely elevated in a subset of patients with IPSID...

The gastrointestinal tract is the site of exciting immunological interactions between the epithelium and the mucosa-associated lymphoid tissue, leading to the immune response to food and microbial antigens in the digestive lumen. The objective of this review is to present the main dysimmune pathologies of the digestive tract leading to an enteropathy. As examples, we describe celiac and non-celiac enteropathies to clarify a florid diagnostic framework, by identifying a spectrum of elementary lesions, which must be confronted with the clinico biological context of the patient to orient the diagnosis...

Sprue-like enteropathy (SLE) is a clinical syndrome similar to celiac disease and has been associated with the use of various angiotensin receptor blockers (ARBs), a class of medications frequently used in the management of hypertension. Currently, there has only been one documented case report which has observed this occurrence with the use of the ARB candesartan. A 90-year-old female patient presented with chronic diarrhea and weight loss of unclear etiology. Diagnostic esophagogastroduodenoscopy and ileocolonoscopy were macroscopically unremarkable, but histological samples revealed complete villous atrophy, chronic mucosal inflammation, and intraepithelial T-lymphocytic infiltration...

Collagenous gastritis is a rare inflammatory condition of unknown etiology defined histologically by subepithelial deposition of collagen bands ≥ 10 µm in the lamina propria. Adults typically present with diarrhea, often attributed to concurrent collagenous sprue or collagenous colitis. Children more commonly present with abdominal pain and anemia, with inflammation typically limited to the stomach. Herein, we present a case of collagenous gastritis in a 38-year-old female with a history of iron deficiency and hypothalamic amenorrhea who presented with a one-year history of microcytic anemia...

Environmental enteric dysfunction (EED) is characterized by malabsorption and diarrhea that result in irreversible deficits in physical and intellectual growth. We sought to define the expression of transport and tight junction proteins by quantitative analysis of duodenal biopsies from patients with EED. Biopsies from Pakistani children with confirmed EED diagnoses were compared to those from age-matched North American healthy controls, patients with celiac disease, and patients with nonceliac disease with villous atrophy or intraepithelial lymphocytosis...

Collagenous gastritis has been reported as a rare cause of nausea, diarrhea, weight changes, and early satiety in female patients. Here, we describe two women aged 43 and 71 years who presented with similar symptoms. Gastric biopsies from both individuals showed thickened, irregular subepithelial collagen bands (>10  μ m). The pathogenesis of collagenous gastritis is poorly understood, but it may be the presenting symptom for many underlying autoimmune conditions. In particular, there is a well-established connection between collagenous disorders of the gastrointestinal tract and celiac sprue, Sjögren syndrome, and lymphocytic colitis; however, none of these conditions had been diagnosed in our patients...
