| 1 | Diagnosis of gluten related disorders: Celiac disease, wheat allergy and non-celiac gluten sensitivity显示文摘Cereal crops and cereal consumption have had a vital role in Mankind's history. In the recent years gluten ingestion has been linked with a range of clinical disorders. Gluten-related disorders have gradually emerged as an epidemiologically relevant phenomenon with an estimated global prevalence around 5%. Celiac disease, wheat allergy and non-celiac gluten sensitivity represent different gluten-related disorders. Similar clinical manifestations can be observed in these disorders, yet there are peculiar pathogenetic pathways involved in their development. Celiac disease and wheat allergy have been extensively studied, while non-celiac gluten sensitivity is a relatively novel clinical entity, believed to be closely related to other gastrointestinal functional syndromes. The diagnosis of celiac disease and wheat allergy is based on a combination of findings from the patient's clinical history and specific tests, including serology and duodenal biopsies in case of celiac disease, or laboratory and functional assays for wheat allergy. On the other hand, non-celiac gluten sensitivity is still mainly a diagnosis of exclusion, in the absence of clear-cut diagnostic criteria. A multimodal pragmatic approach combining findings from the clinical history, symptoms, serological and histological tests is required in order to reach an accurate diagnosis. A thorough knowledge of the differences and overlap in clinical presentation among gluten-related disorders, and between them and other gastrointestinal disorders, will help clinicians in the process of differential diagnosis. | Luca Elli Federica Branchi Carolina Tomba Danilo Villalta Lorenzo Norsa Francesca Ferretti Leda Roncoroni Maria Teresa Bardella | 2015 | World Journal of Gastroenterology2015，21，23： | 8 |
| 2 | Cytoskeleton reorganization and ultrastructural damage induced by gliadin in a three-dimensional in vitro model显示文摘AIM: To evaluate the interplay between gliadin and LoVo cells and the direct effect of gliadin on cytoskeletal patterns.METHODS: We treated LoVo multicellular spheroids with digested bread wheat gliadin in order to investigate their morphology and ultrastructure (by means of light microscopy and scanning electron microscopy), and the effect of gliadin on actin (phalloidin fluorescence)and the tight-junction protein occludin and zonula occluden-1.RESULTS: The treated spheroids had deep holes and surface blebs, whereas the controls were smoothly surfaced ovoids. The incubation of LoVo spheroids with gliadin decreased the number of intracellular actin filaments, impaired and disassembled the integrity of the tight-junction system.CONCLUSION: Our data obtained from an 'in vivolike' polarized culture system confirm the direct noxious effect of gliadin on the cytoskeleton and tight junctions of epithelial cells. Unlike two-dimensional cell culture systems, the use of multicellular spheroids seems to provide a suitable model for studying cell-cell interactions. | Ersilia Dolfini Leda Roncoroni Luca Elli Chiara Fumagalli Roberto Colombo Simona Ramponi Fabio Forlani Maria Teresa Bardella | 2005 | World Journal of Gastroenterology2005，11，48： | 3 |
| 3 | Helicobacter pylori-negative Russell body gastritis:Case report显示文摘Russell body gastritis is an unusual form of chronic gastritis characterized by the permeation of lamina propria by numerous plasma cells with eosinophilic cytoplasmic inclusions.Very few cases have been reported in the literature;the majority of which have shown Helicobacter Pylori(H.pylori)infection,thus suggesting a correlation between plasma cell presence and antigenic stimulation by H.pylori.We present a case of Russell body gastritis in a 78-year-old woman who was undergoing esophagogastroduodenoscopy for epigastric pain.Gastric biopsy of the gastroesophageal junction showed the presence of cells with periodic acid-Schiff-positive hyaline pink bodies.Giemsa staining for H.pylori infection was nega-tive,as well as immunohistochemical detection.The cells with eosinophilic inclusions stained positive for CD138,CD79a,andκand lambda light chains,which confirmed plasma cell origin.In particular,κand lambda light chains showed a polyclonal origin and the patient was negative for immunological dyscrasia.The histological observations were confirmed by ultrastructural examination.The cases reported in the literature associated with H.pylori infection have shown regression of plasma cells after eradication of H.pylori.Nothing is known about the progression of H.pylori-negative cases.The unusual morphological appearance of this type of chronic gastritis should not be misinterpreted during routine examination,and it should be distinguished from other common forms of chronic gastritis.It is mandatory to exclude neoplastic diseases such as gastric carcinoma, lymphoma and plasmocytoma by immunohistochemistry and electron microscopy,which can help with differential diagnosis.The long-term effects of plasma cells hyperactivation are still unknown,because cases of gastric tumor that originated in patients affected by Russell body gastritis have not been described in the literature.We are of the opinion that these patients should be scheduled for endoscopic surveillance. | Alessandro Del Gobbo Luca Elli Paola Braidotti Franca Di Nuovo Silvano Bosari Solange Romagnoli | 2011 | World Journal of Gastroenterology2011，17，9： | 3 |

| 5 | Celiac disease: From pathophysiology to treatment显示文摘Celiac disease, also known as 'celiac sprue', is a chronic inflammatory disorder of the small intestine, produced by the ingestion of dietary gluten products in susceptible people. It is a multifactorial disease, including genetic and environmental factors. Environmental trigger is represented by gluten while the genetic predisposition has been identified in the major histocompatibility complex region. Celiac disease is not a rare disorder like previously thought, with a global prevalence around 1%. The reason of its under-recognition is mainly referable to the fact that about half of affected people do not have the classic gastrointestinal symptoms, but they present nonspecific manifestations of nutritional deficiency or have no symptoms at all. Here we review the most recent data concerning epidemiology, pathogenesis, clinical presentation, available diagnostic tests and therapeutic management of celiac disease. | Ilaria Parzanese Dorina Qehajaj Federica Patrinicola Merica Aralica Maurizio Chiriva-Internati Sanja Stifter Luca Elli Fabio Grizzi | 2017 | World Journal of Gastrointestinal Pathophysiology2017，8，2： | 1 |
| 6 | Non-celiac gluten sensitivity:Time for sifting the grain显示文摘In the last few years, a new nomenclature has been proposed for the disease induced by the ingestion of gluten, a protein present in wheat, rice, barley and oats. Besides celiac disease and wheat allergy, the most studied forms of gluten-related disorders characterized by an evident immune mechanism(autoimmune in celiac disease and Ig E-mediated in wheat allergy), a new entity has been included, apparently not driven by an aberrant immune response: the non-celiac gluten sensitivity(NCGS). NCGS is characterized by a heterogeneous clinical picture with intestinal and extraintestinal symptoms arising after gluten ingestion and rapidly improving after its withdrawal from the diet. The pathogenesis of NCGS is largely unknown, but a mixture of factors such as the stimulation of the innate immune system, the direct cytotoxic effects of gluten, and probably the synergy with other wheat molecules, are clues for the complicated puzzle. In addition, the diagnostic procedures still remain problematic due to the absence of efficient diagnostic markers; thus, diagnosis is based upon the symptomatic response to a gluten-free diet and the recurrence of symptoms after gluten reintroduction with the possibility of an important involvement of a placebo effect. The temporary withdrawal of gluten seems a reasonable therapy, but the timing of gluten reintroduction and the correct patient management approach are have not yet been determined. | Luca Elli Leda Roncoroni Maria Teresa Bardella | 2015 | World Journal of Gastroenterology2015，21，27： | 1 |

| 9 | Role of capsule endoscopy in suspected celiac disease: A European multi-centre study显示文摘AIM To analyze the diagnostic yield(DY), therapeutic impact(TI) and safety of capsule endoscopy(CE).METHODS This is a multi-centre, observational, analytical, retrospective study. A total of 163 patients with suspicion of celiac disease(CD)(mean age = 46.4 ± 17.3 years, 68.1% women) who underwent CE from 2003 to 2015 were included. Patients were divided into four groups: seronegative CD with atrophy(Group-Ⅰ, n = 19), seropositive CD without atrophy(Group-Ⅱ, n = 39), contraindication to gastroscopy(Group-Ⅲ, n = 6), seronegative CD without atrophy, but with a compatible context(Group-Ⅳ, n = 99). DY, TI and the safety of CE were analysed.RESULTS The overall DY was 54% and the final diagnosis was villous atrophy(n = 65, 39.9%), complicated CD(n = 12, 7.4%) and other enteropathies(n = 11, 6.8%; 8 Crohn's). DY for groups Ⅰ to Ⅳ was 73.7%, 69.2%, 50% and 44.4%, respectively. Atrophy was located in duodenum in 24 cases(36.9%), diffuse in 19(29.2%), jejunal in 11(16.9%), and patchy in 10 cases(15.4%). Factors associated with a greater DY were positive serology(68.3% vs 49.2%, P = 0.034) and older age(P = 0.008). On the other hand, neither sex nor clinical presentation, family background, positive histology or HLA status were associated with DY. CE resultschanged the therapeutic approach in 71.8% of the cases. Atrophy was associated with a greater TI(92.3% vs 45.3%, P < 0.001) and 81.9% of the patients responded to diet. There was one case of capsule retention(0.6%). Agreement between CE findings and subsequent histology was 100% for diagnosing normal/other conditions, 70% for suspected CD and 50% for complicated CD.CONCLUSION CE has a high DY in cases of suspicion of CD and it leads to changes in the clinical course of the disease. CE is safe procedure with a high degree of concordance with histology and it helps in the differential diagnosis of CD. | Marisol Luján-Sanchis Enrique Pérez-Cuadrado-Robles Javier Garcia-Lledo José-Francisco Juanmartinena Fernandez Luca Elli Victoria-Alejandra Jiménez-García Juan Egea-Valenzuela Julio Valle-Munoz Cristina Carretero-Ribón Ignacio Fernández-Urién-Sainz Antonio López-Higueras Noelia Alonso-Lazaro Mileidis Sanjuan-Acosta Francisco Sanchez-Ceballos Bruno Rosa Santiago González-Vázquez Federica Branchi Lucía Ruano-Díaz César Prieto-de-Frías Vicente Pons-Beltrán Pilar Borque-Barrera Begona González-Suárez Sofía Xavier Federico Argüelles-Arias Juan-Manuel Herrerías-Gutiérrez Enrique Pérez-Cuadrado-Martínez Javier Sempere-García-Argüelles | 2017 | World Journal of Gastroenterology2017，23，4： | 0 |
| 10 | Mirror,mirror on the wall,who is the best of them all?Artificial intelligence versus gastroenterologists in solving clinical problems显示文摘Introduction Artificial intelligence(AI)is a concept that commonly refers to machines mimicking human cognitive behavior during learning and problem-solving[1].Chatbots are a typical example of an AI system,capable of interacting with humans[2].ChatGPT(OpenAI,San Francisco,CA,USA)[3]is a new-generation chatbot that captures the context and relationship between words in input sequences through multiple layers of self-attention and feedforward neural networks.Then,it predicts the most likely“token”to succeed the previous one based on patterns in its training data.Therefore,it is a self-contained system that does not copy existing information[4]. | Felice Benedicenti Tommaso Pessarelli Mattia Corradi Marco Michelon Nicoletta Nandi Pietro Lampertico Maurizio Vecchi Lucia Scaramella Luca Elli | 2023 | Gastroenterology Report2023，11，1： | 0 |
| 11 | Intestinal ischemic manifestations of SARS-CoV-2:Results from the ABDOCOVID multicentre study显示文摘BACKGROUND Intestinal ischemia has been described in case reports of patients with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)disease(coronavirus disease 19,COVID-19).AIM To define the clinical and histological,characteristics,as well as the outcome of ischemic gastrointestinal manifestations of SARS-CoV-2 infection.METHODS A structured retrospective collection was promoted among three tertiary referral centres during the first wave of the pandemic in northern Italy.Clinical,radiological,endoscopic and histological data of patients hospitalized for COVID-19 between March 1st and May 30th were reviewed.The diagnosis was established by consecutive analysis of all abdominal computed tomography(CT)scans performed.RESULTS Among 2929 patients,21(0.7%)showed gastrointestinal ischemic manifestations either as presenting symptom or during hospitalization.Abdominal CT showed bowel distention in 6 patients while signs of colitis/enteritis in 12.Three patients presented thrombosis of main abdominal veins.Endoscopy,when feasible,confirmed the diagnosis(6 patients).Surgical resection was necessary in 4/21 patients.Histological tissue examination showed distinctive features of endothelial inflammation in the small bowel and colon.Median hospital stay was 9 d with a mortality rate of 39%.CONCLUSION Gastrointestinal ischemia represents a rare manifestation of COVID-19.A high index of suspicion should lead to investigate this complication by CT scan,in the attempt to reduce its high mortality rate.Histology shows atypical feature of ischemia with important endotheliitis,probably linked to thrombotic microangiopathies. | Lorenzo Norsa Pietro Andrea Bonaffini Maja Caldato Cristiana Bonifacio Aurelio Sonzogni Amedeo Indriolo Clarissa Valle Federica Furfaro Alice Bonanomi Paolo NiccolòFranco Mauro Gori Veronica Smania Lucia Scaramella Laura Forzenigo Maurizio Vecchi Monica Solbiati Giorgio Costantino Silvio Danese Lorenzo D'Antiga Sandro Sironi Luca Elli | 2021 | World Journal of Gastroenterology2021，27，32： | 0 |
| 12 | Damaging effects of gliadin on three-dimensional cell culture model显示文摘AIM: To evaluate the effects of gliadin on the oxidative environment in the'in vivo-like' model of a three-dimensional cell culture system.METHODS: LoVo cell line (intestinal adenocarcinoma)multicellular spheroids were treated with digested gliadin (with albumin used as a control). Spheroid volumes, cell viability and morphology, lactate dehydrogenase (LDH)release, content of reduced glutathione (GSH) and activity of GSH-related enzymes were examined. The data were statistically analyzed using the Student's t-test (P<0.05).was considered statistically significant.RESULTS: Gliadin reduced cell viability (from 20% to 60%)and led to morphological alterations characterized by apoptotic findings and cytoskeletal injuries. LDH activity increased. The content of GSH reduced (-20% vs controls),and activity of GSH-related enzymes was significantly inhibited.CONCLUSION: Gliadin treatment induces an imbalance in the antioxidative mechanism of cells cultured by the three-dimensional technique. This alteration may explain the cell damage directly caused by gliadin and the subsequent morphological abnormalities. | Ersilia Dolfini Luca Elli Leda Roncoroni Barbara Costa Maria Pia Colleoni Vito Lorusso Simona Ramponi Paola Braidotti Stefano Ferrero Maria Letizia Falini Maria Teresa Bardella | 2005 | World Journal of Gastroenterology2005，11，38： | 0 |
| 13 | Clinical challenge for gastroenterologists–Gastrointestinal manifestations of systemic mastocytosis:A comprehensive review显示文摘Mastocytosis is a rare and heterogeneous disease characterized by various clinical and biological features that affect different prognoses and treatments.The disease is usually divided into 2 principal categories:cutaneous and systemic disease(SM).Clinical features can be related to mast cell(MC)mediator release or pathological MC infiltration.SM is a disease often hard to identify,and the diagnosis is based on clinical,biological,histological,and molecular criteria with different specialists involved in the patient’s clinical work-up.Among all manifestations of the disease,gastrointestinal(GI)symptoms are common,being present in 14%-85% of patients,and can significantly impair the quality of life.Here we review the data regarding GI involvement in SM,in terms of clinical presentations,histological and endoscopic features,the pathogenesis of GI symptoms,and their treatment. | Alessandra Elvevi Elena Maria Elli Martina Luca Miki Scaravaglio Fabio Pagni Stefano Ceola Laura Ratti Pietro Invernizzi Sara Massironi | 2022 | World Journal of Gastroenterology2022，28，29： | 0 |
