Nutritional and Gastroenterological Monitoring of Patients With Celiac Disease During COVID-19 Pandemic: The Emerging Role of Telemedicine and Point-of-Care Gluten Detection Tests

A systematic review of consumers' and healthcare professionals' trust in digital healthcare

Despite the well-documented importance of trust in digital healthcare, its domains are not well-understood, preventing theoretically robust instruments for standardised measurements. We identified instruments measuring trust in digital healthcare, explored definitions, associated factors, and outcomes. We systematically reviewed the literature using tailored searches and 49 studies measuring trust in digital healthcare from either consumers', healthcare professionals', or both perspectives were included. Trust in digital healthcare is complex and, from a consumers' perspective, can influence digital healthcare use, adoption, acceptance, and usefulness. Consumers' trust can be affected by the degree of human interaction in automated interventions, perceived risks, privacy concerns, data accuracy, digital literacy, quality of the digital healthcare intervention, satisfaction, education, and income. Healthcare professionals' trust is enhanced by education and observing good digital health performance. While studies can benefit from rigorous trust measurements, future efforts should address the need for a theoretical framework for trust in digital healthcare.

Telemedicine in Coeliac Disease: In-Person Appointments Are Favoured by Patients With a Lower Education Attainment and Lower Household Income

INTRODUCTION

A gluten-free (GF) diet, the only treatment for people living with coeliac disease (CD), is challenging, and international guidelines highlight the valuable role of healthcare professionals in enabling self-management. The study aimed to explore the acceptability of telephone and online video consultations for adults with CD.

METHODS

A cross-sectional study consisting of an online and paper survey was promoted to adults with CD.

RESULTS

Data from 496 adults with CD (87% female, 96% White) are presented, and 44% were adhering to the GF diet. Over half (58%) were very confident in understanding food labels from supermarkets, whereas only 38% were very confident when shopping online. The largest proportion of patients preferred in-person healthcare appointments for CD (44%), with 20% reporting no preference and 21% preferring telephone appointments. Only 15% preferred online video consultations; of these, 97% were confident with online technology. A higher proportion of patients from a lower household income requested 'in-person' appointments compared with those with a higher income (65% vs. 45% (p < 0.01)). Likewise, 58% of patients without a degree qualification requested 'in-person' appointments compared with 45% of degree-educated patients (p = 0.027).

CONCLUSIONS

We highlight a significant proportion of adults with CD prefer an in-person appointment. The paper survey enabled the views of a broader range of digitally confident patients to contribute to the study. With a global shift towards telemedicine and online resources, access and digital literacy is an important consideration for equitable healthcare to optimize patient self-management of the GF diet.

Past, Present, and Future of Noninvasive Tests to Assess Gluten Exposure, Celiac Disease Activity, and End-Organ Damage

Although many biomarkers have been proposed, and several are in widespread clinical use, there is no single readout or combination of readouts that correlates tightly with gluten exposure, disease activity, or end-organ damage in treated patients with celiac disease. Challenges to developing and evaluating better biomarkers include significant interindividual variability-related to immune amplification of gluten exposure and how effects of immune activation are manifest. Furthermore, the current "gold standard" for assessment of end-organ damage, small intestinal biopsy, is itself highly imperfect, such that a marker that is a better reflection of the "ground truth" may indeed appear to perform poorly. The goal of this review was to analyze past and present efforts to establish robust noninvasive tools for monitoring treated patients with celiac disease and to highlight emerging tools that may prove to be useful in clinical practice.

Utilizing Telemedicine Applications in Celiac Disease and Other Gluten-Free-Diet-Dependent Conditions: Insights from the COVID-19 Pandemic

BACKGROUND

Globally, approximately 1.4% of people have celiac disease (CD), induced by gluten sensitivity. If left untreated, it causes small intestinal inflammation and villous atrophy, which can result in failure to thrive, anemia, osteoporosis, malabsorption, and even malignancy. The only treatment option available is a gluten-free diet (GFD). Few studies have looked at the role and perception of telehealth in relation to CD and selective nutrition both before and after the COVID-19 pandemic.

AIM

Our goal was to screen and investigate the research conducted both before and after the COVID-19 pandemic concerning the utilization of telehealth applications and solutions in CD and other GFD-dependent circumstances.

METHODS

We employed a narrative review approach to explore articles that were published in scholarly journals or organizations between the years 2000 and 2024. Only English-language publications were included. PubMed and Google Scholar searches were mainly conducted using the following keywords: telemedicine, telehealth, telecare, eHealth, m-health, COVID-19, SARS-CoV-2, celiac disease, and gluten-free diet (GFD). Manual searches of the references in the acquired literature were also carried out, along with the authors' own personal contributions of their knowledge and proficiency in this field.

RESULTS

Only a few studies conducted prior to the COVID-19 outbreak examined the viewpoints and experiences of adult patients with CD with relation to in-person clinic visits, as well as other options such as telehealth. The majority of patients believed that phone consultations were appropriate and beneficial. Video conferencing and telemedicine became more popular during the COVID-19 pandemic, demonstrating the effectiveness of using these technologies for CD on a global basis. In recent years, urine assays for gluten identification have become accessible for use at home. These tests could be helpful for CD monitoring with telemedicine assistance.

CONCLUSIONS

The extended knowledge gathered from the COVID-19 pandemic is expected to complement pre-COVID-19 data supporting the usefulness of telemedicine even after the emergent pandemic, encouraging its wider adoption in standard clinical practice. The monitoring and follow-up of CD patients and other GFD-dependent conditions can greatly benefit from telemedicine.

Guidelines for best practices in monitoring established coeliac disease in adult patients

Coeliac disease (CeD) is an immunological disease triggered by the consumption of gluten contained in food in individuals with a genetic predisposition. Diagnosis is based on the presence of small bowel mucosal atrophy and circulating autoantibodies (anti-type 2 transglutaminase antibodies). After diagnosis, patients follow a strict, life-long gluten-free diet. Although the criteria for diagnosis of this disease are well defined, the monitoring phase has been studied less and there is a lack of specific guidelines for this phase. To develop a set of clinical guidelines for CeD monitoring, we followed the Grading of Recommendations Assessment, Development and Evaluation methodology. Statements and recommendations with the level of evidence were developed and approved by the working group, which comprised gastroenterologists, pathologists, dieticians and biostatisticians. The proposed guidelines, endorsed by the North American and European coeliac disease scientific societies, make recommendations for best practices in monitoring patients with CeD based on the available evidence. The evidence level is low for many topics, suggesting that further research in specific aspects of CeD would be valuable. In conclusion, the present guidelines support clinicians in improving CeD treatment and follow-up and highlight novel issues that should be considered in future studies.

COVID-19 and celiac disease: a review

The aim of this review is to broadly cover how the COVID-19 pandemic has affected individuals with celiac disease, including perceived risk, risk of contraction or severe infection, considerations regarding vaccination, access to gluten-free food during the pandemic, and possible long-term changes to the practice of celiac disease management spurred by the pandemic. While initially there was increased perceived risk about COVID-19 in the celiac disease population, studies have found that individuals with celiac disease are not at an increased risk of contracting or having a severe course compared to the general population. There is not yet evidence that COVID-19 infection will lead to an increase in celiac disease incidence, though more research on this topic with longer-term follow-up is necessary to make this determination. Limited access to in-person visits led to an increase in telemedicine, which was adopted swiftly by this patient population and may offer improved access in the long term. In summary, individuals with celiac disease do not appear to be at an increased risk of contracting COVID-19 or having a more severe disease course.

The low-FODMAP diet and the gluten-free diet in the management of functional abdominal bloating and distension

This review summarizes current knowledge on the role of low-FODMAP diet and gluten-free diet in functional abdominal bloating and distension, an emerging disorder of gut-brain interaction characterized by remarkable costs for healthcare systems and a significant impact on the patient's quality of life. Ingested food plays a key role in the pathophysiology of disorders of gut-brain interaction as up to 84% of patients with irritable bowel syndrome (IBS) report food-triggered symptoms. Potential pathogenetic mechanisms of food-related symptoms in these patients are discussed, focusing on bloating and abdominal distension. These mechanisms provide the rationale for dietary treatment in patients with functional abdominal bloating and distension. The role of fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) and gluten in functional abdominal bloating and distension is examined. Current literature evaluating the efficacy of the low-FODMAP diet and the gluten-free diet in abdominal bloating and distension is analyzed. Available evidence originates mainly from studies on patients with IBS, since clinical studies on selected cohorts of patients with only functional abdominal bloating and distension have been missing to date. Promising evidence on the potential efficacy of the low-FODMAP diet in functional abdominal bloating and distension is provided by the reduction of the bloating observed in patients with IBS. Regarding the gluten-free diet, there is insufficient evidence to recommend it to reduce bloating and abdominal distension. In conclusion, this review asserts the need for a close collaboration with experts in nutrition to optimize the management of these patients and reduce the risks associated with elimination diets.

Diagnostic management of patients reporting symptoms after wheat ingestion

Many patients report symptoms after wheat ingestion experiencing a wide spectrum of clinical manifestations. Three possible diagnoses have been recognized: celiac disease (CD), wheat allergy (WA), and non-celiac (gluten) wheat sensitivity (NCGS/NCWS). CD is a chronic immune-mediated disease of the small bowel caused by exposure to dietary gluten in genetically predisposed individuals, with a prevalence of approximately 1%. It is characterized by mucosal inflammation and atrophy following exposure to gluten and improvement after gluten withdrawal. Food allergies are immunological responses to a food antigen. WA is the expression of an immunologically mediated process that can be immunoglobulin E (IgE) or non-IgE mediated; its many symptoms include urticaria/angioedema, asthma, rhinitis, and anaphylaxis. NCGS/NCWS is characterized by gastrointestinal and/or extra-intestinal symptoms after ingestion of gluten-containing food in subjects not affected by CD or WA. The aim of this review is to help physicians and nutritionists diagnose the cause of symptoms reported after wheat ingestion, thus avoiding patient frustration, inappropriate testing, and incorrect or missed diagnoses. An algorithm for the diagnostic approach in these patients is provided, to help to diagnose CD, WA, NCGS/NCWS or to identify possible functional disorders as the wheat-sensitive irritable bowel syndrome. A personalized approach, regular follow-up, and the help of a skilled healthcare professional are mandatory for patients with symptoms following wheat ingestion is provided. A gluten-free-diet is often recommended for patients with self-reported gluten/wheat-dependent symptoms; for patients with symptoms similar to those of functional diseases while there is evidence that a low-FODMAP diet could be the first option.

Internet of things in the management of chronic diseases during the COVID-19 pandemic: A systematic review

INTRODUCTION

The use of new technologies such as the Internet of Things (IoT) in the management of chronic diseases, especially in the COVID pandemics, could be a life-saving appliance for public health practice. The purpose of the current study is to identify the applications and capability of IoT and digital health in the management of the COVID-19 pandemic.

METHODS

This systematic review was conducted by searching the online databases of PubMed, Scopus, and Web of Science using selected keywords to retrieve the relevant literature published until December 25th, 2021. The most relevant original English studies were included after initial screening based on the inclusion criteria.

RESULTS

Overall, 18 studies were included. Most of the studies reported benefits and positive responses in the form of patients' and healthcare providers' satisfaction and trust in the online systems. Many services were provided to the patients, including but not limited to training the patients on their conditions; monitoring vital signs and required actions when vital signs were altered; ensuring treatment adherence; monitoring and consulting the patients regarding diet, physical activity, and lifestyle.

CONCLUSION

IoT is a new technology, which can help us improve health care services during the COVID-19 pandemic. It has a network of various sensors, obtaining data from patients. We have found several applications for this technology. Future studies can be conducted for the capability of other technologies in the management of chronic diseases.

Maintaining, Managing, and Tele-Monitoring a Nutritionally Adequate Mediterranean Gluten-Free Diet and Proper Lifestyle in Adult Patients

The gluten-free diet (GFD) is a restrictive diet. In many cases, it must be permanent and strict, and it may be associated with both nutritional deficiencies and excesses, which can be prevented by following a healthy, natural Mediterranean GFD (Med-GFD). In this paper, we describe the importance of the Mediterranean diet, the correct intake of vitamins and minerals, and how they may play an important protective role against chronic or degenerative conditions. Herewith, we analyze different aspects that influence the ability to maintain a correct and balanced Med-GFD, which may contribute to the health status of patients, including a conscious use of gluten-free products to maintain a healthy lifestyle. Monitoring the Med-GFD remains a pivotal issue: to evaluate the presence of gluten peptides in urine, it could be important to introduce point-of-care testing, an efficient method for GFD self-monitoring (immunochromatographic technique), together with online nutritional questionnaires. Indeed, medical care via telemedicine can provide practical indications aimed at supporting patients and doctors. A natural Med-GFD can ensure the correct intake of nutrients and could be important for patients affected by gluten-related disorders, helping them to maintain a correct and healthy lifestyle.

Correct use of telemedicine in gastroenterology, hepatology, and endoscopy during and after the COVID-19 pandemic: Recommendations from the Italian association of hospital gastroenterologists and endoscopists (AIGO)

The purpose of the present document is to provide detailed information on the correct and optimal use of digital media to ensure continuity of care for gastroenterological patients in everyday clinical practice, in health emergencies and/or when the patient cannot reach the hospital for other reasons. During the recent COVID-19 pandemic, telemedicine has allowed many patients with chronic diseases to access remote care worldwide, proving to be the ideal solution to overcome restrictions and carry out non-urgent routine follow-ups on chronic patients. The COVID-19 pandemic has therefore made organizational and cultural renewal essential for the reorganization of healthcare in order to ensure greater continuity of care with a minimum risk of spreading the virus to users, practitioners and their families. These AIGO recommendations are intended to provide Italian gastroenterologists with a tool to use this method appropriately, in compliance with current legislation, in particular the proper approach and procedures for conducting a remote examination using a video conferencing tool, the so-called televisit. In the near future, telemedicine may contribute to a possible reorganization of healthcare systems, through innovative care models focusing on the citizen and facilitating access to services throughout the entire Country.
