Abstract
Celiac disease and other types of gluten intolerance significantly affect the life quality of patients making them restrict the diet removing all food produced from wheat, rye, oat, and barley flour, and some other products. These disorders arise from protease resistance of poorly soluble proteins prolamins, contained in gluten. Enhanced proteolytic digestion of gliadins might be considered as a prospective approach for the treatment of celiac disease and other types of gluten intolerance. Herein, we tested a range of sulfated polymers (kappa-carrageenan, dextran sulfate and different polysaccharides from brown seaweeds, and a synthetic polystyrene sulfonate) for the ability to activate gliadin digestion by human digestive proteases, pepsin and trypsin. Sulfated polysaccharide from Fucus evanescens enhanced proteolytic digestion of gliadins from wheat flour and reduced its cytotoxicity on intestinal epithelial Caco-2 cell culture. Regarding the non-toxic nature of fucoidans, the results provide a basis for polymer-based drugs or additives for the symptomatic treatment of gluten intolerance.

Consumer Awareness and Acceptance of Biotechnological Solutions for Gluten-Free Products. Foods 2023; 12:foods12091808.

Abstract
Celiac disease is an immune-mediated disorder caused by the ingestion of gluten proteins. The gluten-free diet is currently the only therapy to achieve the symptoms' remission. Biotechnological approaches are currently being explored to obtain safer and healthier food for celiacs. This article analyzes consumer awareness and acceptance of advanced biotechnologies to develop gluten-free products. An online snowball sampling questionnaire was proposed to 511 Italian participants, selected among celiac and non-celiac people, from December 2020 to January 2021, during the second wave of the COVID-19 pandemic. Overall, 64% of respondents favor food biotechnology, as long as it has benefits for health or the environment. Moreover, biotechnology perception differs according to education level and type. A total of 65% of the survey participants would taste gluten-free products obtained through a biotechnological approach, and 57% would buy them at a higher price than the current market price. Our results show a change in public opinion about the usefulness of food biotechnology and its moral acceptability compared to 20 years ago. However, the study of public opinion is very complex, dealing with individuals with social, economic, and cultural differences. Undoubtedly, the scientific dissemination of genetic biotechnologies must be more effective and usable to increase the level of citizens' awareness.

Abstract
Celiac disease (CD) is a common autoimmune disease affecting around 1% of the population. It consists of an immune-mediated enteropathy, triggered by gluten exposure in susceptible patients. All patients with CD, irrespective of the presence of symptoms, must endure a lifelong gluten-free diet (GFD). This is not an easy task due to a lack of awareness of the gluten content in foods and the extensive incorporation of gluten in processed foods. Furthermore, a GFD imposes a sense of limitation and might be associated with decreased quality of life in CD patients. This results in gluten contamination in the diet of four out of five celiac patients adhering to a GFD. Furthermore, one in three adult patients will report persistent symptoms and two in three will not achieve full histological recovery when on a GFD. In recent years, there has been extensive research conducted in the quest to find the holy grail of pharmacological treatment for CD. This review will present a concise description of the current rationale and main clinical trials related to CD drug therapy.

Abstract
We present a case report of a boy diagnosed with both chronic granulomatous disease (CGD) and familial celiac disease (CD) who underwent cord blood transplantation from a partially matched sibling donor. The presentation of CD resembled Crohn-like enteropathy, which is a canonical manifestation of CGD. Nearly 1 year post-hematopoietic stem cell transplantation (HSCT), a gluten-containing diet was reintroduced, and no reappearance of clinical, serologic, or histologic markers of CD was observed. The relatively high incidence of rare genetic diseases in pediatric patients suggests the need for additional caution in the interpretation of symptoms mimicking already known hallmarks of more common conditions. In addition, the presented data confirm the previous rare observations that allogeneic HSCT leads to durable induction of gluten tolerance in patients with CD, which can warrant its use in patients with refractory subtypes of CD.

Abstract
Historically, a gluten-free diet was recommended only for those with celiac disease or IgE-mediated wheat allergy. With changes in food allergy labeling in the United States and the publication of several best-selling books, gluten-related disorders have come to the forefront of popular culture. As a result, there has been a dramatic increase in the number of gluten-free diet followers, many for nontraditional reasons. As "going gluten-free" has become mainstream, it is imperative that health care providers acquire the knowledge to identify true gluten-related disorders to effectively counsel their patients and minimize potential complications from following such a restrictive diet.

Abstract
Gluten-related disorders (GRD) affect millions of people worldwide and have been related to the composition and metabolism of the gut microbiota. These disorders present differently in each patient and the only treatment available is a strict life-long gluten-free diet (GFD). Several studies have investigated the effect of a GFD on the gut microbiota of patients afflicted with GRD as well as healthy people. The purpose of this review is to persuade the biomedical community to think that, while useful, the results from the effect of GFD on health and the gut microbiota cannot be extrapolated from one population to others. This argument is primarily based on the highly individualized pattern of gut microbial composition and metabolic activity in each person, the variability of the gut microbiota over time and the plethora of factors associated with this variation. In addition, there is wide variation in the composition, economic viability, and possible deleterious effects to health among different GFD, both within and among countries. Overall, this paper encourages the conception of more collaborative efforts to study local populations in an effort to reach biologically and medically useful conclusions that truly contribute to improve health in patients afflicted with GRD.
