Physicians' attitude and perception regarding celiac disease: A questionnaire-based study

Knowledge of Health Students Regarding Nutritional Deficiencies in Patients With Celiac Disease in Jazan Region: A Cross-Sectional Study

INTRODUCTION

In Saudi Arabia, the prevalence of celiac disease (CeD) was 2.7% greater than the global pooled prevalence of 1.4%. Patients who strictly adhere to a lifetime gluten-free diet (GFD) may develop nutritional deficiencies potentially contributing to obesity, increased cardiovascular risk, and lower bone density. Therefore, this study aims to assess the knowledge of health students in the Jazan region regarding nutritional deficiencies in patients with CeD who are on a GFD and to determine the associated socio-demographic factors.

METHODS

A descriptive cross-sectional study was conducted among health college students of Jazan University, including students from the College of Medicine, Pharmacy, Nursing, Dentistry, Public Health and Health Informatics, and Allied Health Sciences, aged 18 and above, excluding internship students, students who did not complete the survey, and those who refused to participate. The minimum calculated sample size was 368. The questionnaire was adopted from the literature and translated into Arabic. It contained a socio-demographic section and a knowledge section that included 12 questions focusing on the content of macro- and micronutrients in a GFD and the impact of the diet on the health of patients with CeD.

RESULTS

The study included 369 participants, with 235 (64%) aged 17-22, 280 (76%) being females, and 341 (92%) being single. The College of Medicine and the College of Applied Medical Sciences had the highest representation, and the College of Dentistry was the lowest. Most participants were in the fourth year (30%) and sixth year (24%). The grade point average (GPA) had a median of 4.3. Approximately 59.1% were aware of nutritional deficiencies among CeD patients. None of the sociodemographic factors were associated with health students' knowledge regarding CeD. Participants from the College of Pharmacy had a lower knowledge of CeD nutrient deficiencies than those from the College of Medicine. (OR: 0.45, 95% CI: 0.22, 0.90). Most students stated that CeD patients should be advised to take multivitamin drugs and vitamin D supplements. Most acknowledged vitamin D, vitamin B12, and folic acid deficiencies in CeD patients. Similarly, most were aware of iron and calcium deficiencies, with a small percentage aware of zinc and copper.

CONCLUSION

Approximately 59.1% had an acceptable level of knowledge, which is considered a low knowledge level among students who will be future physicians and healthcare workers to whom CeD will represent the first-line disease exposed to. Rising knowledge and awareness among those students will guarantee correct diagnosis, treatment, and better outcomes among CeD patients, thus decreasing the disease burden and increasing the quality of those patients.

Is there any association between celiac disease, myelodysplastic symdrome and primary sclerosing cholangitis?: A rare case report

Celiac disease (CD) is an autoimmune disease characterized by a specific serological and histological profile. Hematological findings are one of the most common presentations and can sometimes be the only manifestation of the disease. In patients with unexplained isolated hematological abnormalities, a high index of suspicion for CD is necessary. A 33-year-old woman was admitted to the Department of Gastroenterology and Hepatology because of abdominal pain and fatigue. She was diagnosed with myelodysplastic syndrome. After many investigations, it is explained that she has CD. It is important to consider myelodysplastic syndrome as a hematological manifestation of CD. All patients with myelodysplasia should be investigated for CD and related conditions such as primary sclerosing cholangitis.

Prevalence of Coagulopathy in Patients with Celiac Disease: A Single-Center Retrospective Case-Control Study

Introduction: Despite being one of the most frequent chronic digestive diseases worldwide, with a prevalence of 1%, celiac disease (CD) remains severely underdiagnosed. Among the instruments used to improve its diagnostic rate, hematologic parameters have been proposed as screening tests to select patients with an increased probability of having CD. Assessment of coagulation is included in routine check-ups, and CD has been reported to be associated with coagulopathy. We aimed to assess if subtle changes in coagulation tests could be used in clinical practice to prompt testing for CD. Methods: We retrospectively recruited all patients with clinical suspicion for CD during a study period of 7 years (between 2015 and 2022), who were tested using IgA tissue transglutaminase (tTG) serology and serum total IgA (IgG tTG in case of IgA deficiency) and who underwent upper gastrointestinal endoscopy with multiple biopsy sampling of the duodenal bulb and distal duodenum. We stratified patients into three groups: newly diagnosed CD, gluten-free diet-treated CD, and non-CD controls. Results: Altogether, there were 133 CD patients (71 newly diagnosed, 62 GFD-treated) and 57 non-CD controls. Mean age and gender distribution were similar among the three groups: 43.3 years for newly diagnosed CD, 41.6 years for non-CD controls, and 44 years for GFD-treated CD patients, with a male gender distribution of 21.1%, 28%, and 24.1%, respectively. Among the included newly diagnosed CD patients, 14% had a prolonged INR. The mean INR was slightly higher in newly diagnosed CD patients, compared to GFD-treated CD patients and non-CD controls: 1.12 ± 0.30, 1.02 ± 0.83, and 1.00 ± 0.08, respectively (p = 0.009). Consequently, prothrombin activity was slightly lower in newly diagnosed CD patients, compared to GFD-treated CD and non-CD controls: 94.9 ± 19.3%, 102.3 ± 12.8%, and 101.9 ± 15.15, respectively. Interestingly, after GFD, the mean INR and prothrombin activity of CD individuals reached a value similar to that of non-CD controls. Conclusions: Subtle changes in INR, defined as a value within the normal range, but closer to the upper limit, could be an indicator of probability for CD.

The Role of Physicians' Factors in Underdiagnosis of Celiac Disease in the Eastern Province of Saudi Arabia

Background Celiac disease is an autoimmune disorder triggered by gluten and related prolamines, which can cause a variety of symptoms and complications if left untreated. Despite being a common lifelong disorder, it often goes undiagnosed for a long time, leading to negative impacts on patients' health and quality of life. The diagnosis of celiac disease requires the presence of celiac-specific autoantibodies and distinctive histological changes in the small intestinal mucosa. Lack of disease knowledge among healthcare professionals and patients' adherence to gluten-free diets may contribute to diagnostic delays. Objectives This study aims to assess the reasons for celiac disease underdiagnosis and identify the functional deficiencies of healthcare professionals in the diagnosis and treatment of celiac disease, particularly in the Saudi population. Materials and methods A cross-sectional, questionnaire-based study was conducted among physicians in the Eastern Province of Saudi Arabia during the year 2023, between May and July. Participants were asked to complete an online self-administered questionnaire that included questions about their demographic characteristics, professional experience, and knowledge and attitudes toward celiac disease. The study recruited gastroenterologists, gastroenterology fellows, internal and family medicine specialists, residents, and general practitioners working in private or public health centers in various cities of the Eastern Province. Results The data were collected from 180 physicians who fulfilled the inclusion criteria of the study, with most participants aged under 30 years and predominantly male. Family medicine and general practitioners were the most represented specialties. While 49.4% of physicians knew that adult celiac disease was rare, only 19.4% frequently recommended celiac disease serology to their patients. In terms of risk, most physicians knew that adult celiac disease was a moderately severe and disabling disease, but only 24.4% thought that the cancer risk in patients with celiac disease was moderate. About 75.6% of physicians had an overall poor knowledge level regarding celiac disease, with gastroenterologists and internal medicine specialists demonstrating better knowledge compared to other specialties (P = 0.001). Conclusion The study found that a majority of physicians in the Eastern Province of Saudi Arabia had poor knowledge about celiac disease. This lack of knowledge could have implications for patient care, as it could lead to delays in diagnosis, inadequate treatment, and increased risk of complications.

The Opinion of Polish Coeliac Patients on the Knowledge of Medical Professionals and Support Groups about Coeliac Disease-A Pilot Study

A high quality of knowledge and how it is communicated by healthcare professionals (HCPs) let the patient understand coeliac disease (CD) and result in better adherence to therapeutic recommendations. Therefore, the aim of the current study was to assess the opinion of Polish respondents with CD on the comprehension of CD among Polish HCPs. The analysis was based on 796 responses from patients (the members of the Polish Coeliac Society) with confirmed CD diagnosis (224; 28.1% children and 572; 71.9% adults). The most frequently consulted HCPs regarding CD symptoms in the analysed group were gastroenterologists, and various support groups and associations for CD patients. Furthermore, their comprehension of CD was rated best, as 89.3% (n = 552) of the patients who had contact with support groups and associations classified their knowledge on CD as good. More than a half of the respondents (n = 310, 56.6%) who had contact with general practitioners (GPs) due to their symptoms, rated the doctor's knowledge on CD as bad. Nurses' comprehension on CD was classified as bad by 45 (52.3%) respondents who had contact with a nurse. Out of 294 Polish patients with CD who had contact with a dietician, 247 (84.0%) assessed that the dietician communicated their knowledge on CD well. The respondents rated that GPs and nurses communicated their knowledge on CD in the worst manner (60.4% and 58.1%, respectively). Out of 796 respondents, 792 (99.5%) provided information about the number of appointments with GPs due to symptoms that occurred prior to CD diagnosis. The respondents had contact with GPs 13 863 times before obtaining a CD diagnosis due to their symptoms. After the establishment of a CD diagnosis, the number of appointments with GPs decreased to 3850, and the average number of appointments decreased from 17.8 to 5.1. The respondents assessed that the knowledge on CD of HCPs is not satisfactory. The work of support groups and associations on CD, who promote reliable CD diagnosis and treatment methods, should be promoted. The cooperation between various HCPs needs to be encouraged, which may lead to better compliance.

Knowledge regarding celiac disease among healthcare professionals, patients and their caregivers in Turkey

BACKGROUND

Celiac disease (CD) is one of the most prevalent chronic disorders. The clinical manifestations of CD are diverse and may present with gastrointestinal findings, extra-intestinal findings or no symptoms. Although there has been a marked increase in the prevalence of CD in the past 30 years, up to 95% of patients with CD remain undiagnosed. As most cases have atypical signs or no symptoms, the diagnosis of CD is either missed or delayed. In addition, one of the most important reasons for the delay in diagnosis may be the poor knowledge of healthcare professionals (HCPs) regarding CD.

AIM

To evaluate the knowledge of HCPs, patients and their caregivers (parents) regarding CD.

METHODS

The current study was carried out between June 2021 and February 2022 prospectively, as part of the Focus IN CD project. Patients with CD and their caregivers participated in the study from 6 different cities in Turkey. General practitioners, pediatricians, pediatricians with other subspecialities and pediatric gastroenterologists from different cities participated in the study.

RESULTS

The questionnaire was completed by 348 HCPs, 34 patients with CD, and 102 mothers and 34 fathers of patients with CD. Most of the participants were general practitioners (37.07%). There were 89 (25.57%) pediatricians and 72 (20.69%) pediatric gastroenterologists in the study. The highest score in all categories was achieved by pediatric gastroenterologists. There were significant differences between the four groups of HCPs in terms of the subsections of overall mean score, epidemiology and clinical presentation, treatment and follow-up. No significant difference was found between the groups (patients with CD, mothers of patients with CD and fathers of patients with CD) in terms of the questionnaire subsections.

CONCLUSION

The level of knowledge on CD among HCPs, patients and their caregivers was unsatisfactory. We consider that it is necessary to increase awareness and to develop e-learning activities on CD among HCPs, patients and their caregivers. Consequently, they may benefit from e-learning programs similar to the one created as part of the EU-funded project Focus IN CD (https://www.celiacfacts.eu/focusincd-en).

Current knowledge and "myths" about celiac disease among physicians in the Republic of Kazakhstan: A countrywide cross-sectional study

Background

Celiac disease (CD) is a common genetically predisposed autoimmune condition affecting the gut and other organs. Disease awareness is one of the key components of early case identification. This study aimed to assess awareness about CD among primary care physicians, who are the front-liners in suspecting the diagnosis, and other medical specialists.

Methods and findings

The questionnaire for this survey-based study was created based on the latest international guidelines on CD and included a consent form, 5 general questions (age, gender, etc.), and 10 specific questions concerning CD. Overall, 232 respondents from 13 country provinces (out of 14) and two republican cities were recruited for this study. Of them, 110 (47.4%) were primary care physicians and 122 (52.6%) other medical specialists, including 10 (4.3%) gastroenterologists. A scoring system was used to classify the level of awareness of participants into 3 categories, namely, poor, fair, and good. Analysis of responses revealed poor awareness in 59.4% of physicians, associated with work in republican/province/district/rural/village hospitals (p = 0.004), male gender (p = 0.006), and age of 40-50 years (p = 0.02). The most common "myths" about CD were the following: "symptoms are always obvious in children" or "in adults" (92.5 or 88.4% of respondents, respectively); "genetic mutation HLA DQ2/DQ8 causes the development of CD in all carriers of the mutation" (51.3%); "CD is a disease of children only" (12.5%); and "is triggered by dairy products" (8.6%). Genotyping of HLA DQ genes has been recommended in case of CD suspicion by every third respondent and was advocated as a "golden standard" confirmatory test by every fifth respondent. A quarter of respondents revealed their incorrect treatment strategies: gluten-free diet for 1 month, dairy-free diet, Helicobacter pylori eradication therapy, or responded that did not know how to treat. Overall, 93.5% of respondents expressed intention to learn more about CD, while the rest 6.5% thought that they knew enough, although their knowledge was poor.

Conclusion

This study revealed a poor level of awareness among physicians in Kazakhstan and identified common misconceptions about CD, which potentially could lead to incorrect application of diagnostic tests, delay in diagnosis, and inefficient treatment. Development and implementation of educational programs as well as promotion of self-learning would increase awareness and unravel misconceptions.

Pancreatic involvement in celiac disease

Celiac disease (CD) is well recognized as a systemic, chronic autoimmune disease mainly characterized by gluten-sensitive enteropathy in genetically predisposed individuals but with various extraintestinal features. One of the affected organs in CD is the pancreas, consisting of both endocrine and exocrine alterations. Over the last decades there has been increasing interest in the pancreatic changes in CD, and this has been reflected by a great number of publications looking at this extraintestinal involvement during the course of CD. While pancreatic endocrine changes in CD, focusing on type 1 diabetes mellitus, are well documented in the literature, the relationship with the exocrine pancreas has been less studied. This review summarizes currently available evidence with regard to pancreatic exocrine alterations in CD, focusing on risk of pancreatitis in CD patients, association with autoimmune pancreatitis, prevalence and outcomes of pancreatic exocrine insufficiency in newly diagnosed and gluten-free diet treated CD patients, and the link with cystic fibrosis. In addition, we discuss mechanisms behind the associated pancreatic exocrine impairment in CD and highlight the recommendations for clinical practice.

Knowledge of Medical Students and Medical Professionals Regarding Nutritional Deficiencies in Patients with Celiac Disease

A gluten-free diet provides relief from symptoms for patients with celiac disease, although there is still a risk of nutritional deficiencies. These patients can potentially consume an excessive amount of fat and insufficient amounts of fiber, iron, vitamin D, and calcium. This study aimed to assess the knowledge of medical students and healthcare professionals in Poland regarding nutritional deficiencies and the prevention of such deficiencies in patients with celiac disease who are on a gluten-free diet. Of the 430 survey participants, 46% did not realize the risk of nutritional deficiencies in patients with celiac disease. The knowledge of the participants was lowest regarding the risk of being overweight or obese. Among the healthcare professionals, an acceptable level of correct answers was provided by only 37% of individuals and was highest for the dietitians’ group. Our results demonstrate the need to improve the education of healthcare professionals concerning nutrition in patients with celiac disease.

The Knowledge About Celiac Disease Among Healthcare Professionals and Patients in Central Europe

OBJECTIVES

Celiac disease (CD) remains undiagnosed for a long time in many adult and pediatric patients. We assessed the knowledge about CD among healthcare professionals (HCPs) and CD patients in Central Europe (CE).

METHODS

HCPs and CD patients from 5 CE countries were asked to complete the web-based questionnaire about CD. The questions were divided into subsections on epidemiology, clinical presentation, diagnostics, treatment, and follow-up. Achieved scores of different specialists managing patients with CD were compared and regional differences in patients' knowledge were analyzed.

RESULTS

Questionnaire was completed by 1381 HCPs and 2262 CD patients or their caregivers from Croatia, Hungary, Germany, Italy, and Slovenia. Mean score achieved by HCPs was 50.9%, and by CD patients 56.4%. Pediatric gastroenterologists scored the highest (69.4%; P < 0.001). There were significant differences in knowledge of patients from different CE regions with German participants scoring the highest (58.3%). Members of CD societies scored higher compared with nonmembers (mean score 58% vs 53.2%; P < 0.001) and patients diagnosed less than 5 years ago scored higher compared with those diagnosed more than 10 years ago (mean score 57.3% vs 54.6%; P < 0.001).

CONCLUSIONS

The knowledge about CD among HCPs and CD patients is not satisfactory. Further awareness-raising and learning activities are needed to improve HCPs' knowledge and to minimize the number of unrecognized patients and unnecessary diagnostic delays. Patients should be better informed about their disease to reach higher compliance with the gluten-free diet.

Risk perception and knowledge of COVID-19 in patients with celiac disease

BACKGROUND

We recently demonstrated that the odds of contracting coronavirus disease 2019 (COVID-19) in patients with celiac disease (CeD) is similar to that of the general population. However, how patients with CeD perceive their COVID-19 risk may differ from their actual risk.

AIM

To investigate risk perceptions of contracting COVID-19 in patients with CeD and determine the factors that may influence their perception.

METHODS

We distributed a survey throughout 10 countries between March and June 2020 and collected data on demographics, diet, COVID-19 testing, and risk perceptions of COVID-19 in patients with CeD. Participants were recruited through various celiac associations, clinic visits, and social media. Risk perception was assessed by asking individuals whether they believe patients with CeD are at an increased risk of contracting COVID-19 when compared to the general population. Logistic regression was used to determine the influencing factors associated with COVID-19 risk perception, such as age, sex, adherence to a gluten-free diet (GFD), and comorbidities such as cardiac conditions, respiratory conditions, and diabetes. Data was presented as adjusted odds ratios (aORs)

RESULTS

A total of 10737 participants with CeD completed the survey. From them, 6019 (56.1%) patients with CeD perceived they were at a higher risk or were unsure if they were at a higher risk of contracting COVID-19 compared to the non-CeD population. A greater proportion of patients with CeD perceived an increased risk of contracting COVID-19 when compared to infections in general due to their CeD (56.1% vs 26.7%, P < 0.0001). Consequently, 34.8% reported taking extra COVID-19 precautions as a result of their CeD. Members of celiac associations were less likely to perceive an increased risk of COVID-19 when compared to non-members (49.5% vs 57.4%, P < 0.0001). Older age (aOR: 0.99; 95%CI: 0.99 to 0.99, P < 0.001), male sex (aOR: 0.84; 95%CI: 0.76 to 0.93, P = 0.001), and strict adherence to a GFD (aOR: 0.89; 95%CI: 0.82 to 0.96, P = 0.007) were associated with a lower perception of COVID-19 risk and the presence of comorbidities was associated with a higher perception of COVID-19 risk (aOR: 1.38; 95%CI: 1.22 to 1.54, P < 0.001).

CONCLUSION

Overall, high levels of risk perceptions, such as those found in patients with CeD, may increase an individual’s pandemic-related stress and contribute to negative mental health consequences. Therefore, it is encouraged that public health officials maintain consistent communication with the public and healthcare providers with the celiac community. Future studies specifically evaluating mental health in CeD could help determine the consequences of increased risk perceptions in this population.

Small Bowel Capsule Endoscopy and artificial intelligence: First or second reader?

Several machine learning algorithms have been developed in the past years with the aim to improve SBCE (Small Bowel Capsule Endoscopy) feasibility ensuring at the same time a high diagnostic accuracy. If past algorithms were affected by low performances and unsatisfactory accuracy, deep learning systems raised up the expectancy of effective AI (Artificial Intelligence) application in SBCE reading. Automatic detection and characterization of lesions, such as angioectasias, erosions and ulcers, would significantly shorten reading time other than improve reader attention during SBCE review in routine activity. It is debated whether AI can be used as first or second reader. This issue should be further investigated measuring accuracy and cost-effectiveness of AI systems. Currently, AI has been mostly evaluated as first reader. However, second reading may play an important role in SBCE training as well as for better characterizing lesions for which the first reader was uncertain.

Celiac disease and Sjögren’s syndrome: A case report and review of literature

BACKGROUND

Celiac disease (CD) is a systemic, chronic immune-mediated disease triggered by gluten ingestion in genetically-susceptible individuals, with a prevalence of 1% worldwide. Sjogren's syndrome (SS) is also a systemic autoimmune disease, mainly characterized by ocular and oral sicca symptoms and signs. Sharing a common genetic background, CD and SS are known associated autoimmune diseases, but currently available guidelines are not reporting it.

CASE SUMMARY

We report the case of a 39-year-old woman, who was in the care of her rheumatologist for 2 years with SS. On routine follow-up she was found to have iron deficiency, without anemia. She had no gastrointestinal complaints and denied any obvious source of blood loss. IgA tissue transglutaminase antibodies were positive and endoscopy with duodenal biopsies revealed crypt hyperplasia and villous atrophy. A diagnosis of CD was set and gluten-free diet was recommended.

CONCLUSION

We present a review of existing data in the literature regarding the association of the two diseases, summarizing prevalence studies of CD in SS patients and the other way around. Screening recommendations and future research perspectives are also discussed, highlighting clinically relevant unanswered questions with respect to the association of CD with SS.

Current Evidence on Computer-Aided Diagnosis of Celiac Disease: Systematic Review

Celiac disease (CD) is a chronic autoimmune disease that occurs in genetically predisposed individuals in whom the ingestion of gluten leads to damage of the small bowel. It is estimated to affect 1 in 100 people worldwide, but is severely underdiagnosed. Currently available guidelines require CD-specific serology and atrophic histology in duodenal biopsy samples for the diagnosis of adult CD. In pediatric CD, but in recent years in adults also, nonbioptic diagnostic strategies have become increasingly popular. In this setting, in order to increase the diagnostic rate of this pathology, endoscopy itself has been thought of as a case finding strategy by use of digital image processing techniques. Research focused on computer aided decision support used as database video capsule, endoscopy and even biopsy duodenal images. Early automated methods for diagnosis of celiac disease used feature extraction methods like spatial domain features, transform domain features, scale-invariant features and spatio-temporal features. Recent artificial intelligence (AI) techniques using deep learning (DL) methods such as convolutional neural network (CNN), support vector machines (SVM) or Bayesian inference have emerged as a breakthrough computer technology which can be used for computer aided diagnosis of celiac disease. In the current review we summarize methods used in clinical studies for classification of CD from feature extraction methods to AI techniques.

The Use of Biopsy and "No-Biopsy" Approach for Diagnosing Paediatric Coeliac Disease in the Central European Region

Objectives

The current European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) guidelines introduced the option to diagnose coeliac disease (CD) in children and adolescents without upper endoscopy if the defined criteria are met. The aim of our study was to evaluate how frequently paediatric gastroenterologists in Central Europe used the “no-biopsy” approach and how often the duodenal biopsy could have been omitted.

Methods

Medical records of patients aged < 19 years diagnosed with CD in 2016 from five European countries were analysed, focusing on levels of transglutaminase antibodies (TGA) at the time of diagnosis and on whether the diagnosis was confirmed using duodenal biopsy or “no-biopsy” approach. Clinical presentation and delays until final diagnosis were analysed according to diagnostic approach.

Results

Data from 653 children (63.9% female, median age: 7 years, range: 7 months-18.5 years) from Croatia, Hungary, Germany, Italy, and Slovenia were analysed. One fifth (n = 134) of included children were asymptomatic at diagnosis. Of 519 symptomatic children, 107 (20.6%) were diagnosed by the “no-biopsy” approach. Out of the remaining 412 children who underwent duodenal biopsies, 214 (51.9%) had TGA ≥ 10 times upper level of normal (ULN) and would have been eligible for the “no-biopsy” approach. Signs and symptoms of malabsorption were more frequent in children diagnosed without duodenal biopsies. There were no differences in diagnostic delays with respect to the diagnostic approach.

Conclusion

In this cohort, about 60% of symptomatic CD patients could have been diagnosed without duodenal biopsies. The aim of the “no-biopsy” approach was to make the diagnostic procedure less challenging without compromising its reliability. However, this option was applied only in 20%, in spite of fewer burdens to the family and reduced costs. The reasons for this discrepancy are unknown. Physicians should be made more aware about the reliability of CD diagnosis without biopsies when the ESPGHAN guidelines for CD diagnosis are followed.

Diagnosing Celiac Disease: Towards Wide-Scale Screening and Serology-Based Criteria?

Celiac disease is one of the most common food-related chronic disorders in children. Unfortunately, this multifaceted disease is challenging to recognize and remains markedly underdiagnosed. Screening of either known at-risk groups or even the whole population could increase the suboptimal diagnostic yield substantially. Many recent guidelines recommend screening of at least selected risk groups, but more wide-scale screening remains controversial. The increasing prevalence of celiac disease and the development of autoantibody assays have also led to a gradual shift in the diagnostics towards less invasive serology-based criteria in a subgroup of symptomatic children. The main open questions concern whether these criteria are applicable to all countries and clinical settings, as well as to adult patients. On the other hand, widening screening and the mistaken practice of initiating a gluten-free diet before the appropriate exclusion of celiac disease increase the number of borderline seropositive cases, which may also challenge the classical histopathological diagnostics. Sophisticated diagnostic methods and a deeper understanding of the natural history of early developing celiac disease may prove useful in these circumstances.

Hematologic Manifestations in Celiac Disease-A Practical Review

Celiac disease (CD) is a systemic autoimmune disease driven by gluten-ingestion in genetically predisposed individuals. Although it primarily affects the small bowel, CD can also involve other organs and manifest as an extraintestinal disease. Among the extraintestinal features of CD, hematologic ones are rather frequent and consist of anemia, thrombocytosis (thrombocytopenia also, but rare), thrombotic or hemorrhagic events, IgA deficiency, hyposplenism, and lymphoma. These hematologic alterations can be the sole manifestation of the disease and should prompt for CD testing in a suggestive clinical scenario. Recognition of these atypical, extraintestinal presentations, including hematologic ones, could represent a great opportunity to increase the diagnostic rate of CD, which is currently one of the most underdiagnosed chronic digestive disorders worldwide. In this review, we summarize recent evidence regarding the hematological manifestations of CD, with focus on practical recommendations for clinicians.

Celiac crisis, a rare occurrence in adult celiac disease: A systematic review

BACKGROUND

Celiac crisis (CC), a potentially life-threatening condition, is one of the rare clinical presentations of celiac disease (CD). Several cases have been documented in the literature, mostly in children.

AIM

To perform a review of CC cases reported in adult CD patients.

METHODS

A systematic search of the literature was conducted in two databases, PubMed/MEDLINE and EMBASE, using the term "celiac crisis" and its variant "coeliac crisis", from January 1970 onwards. Altogether, 29 articles reporting 42 biopsy-proven cases were found in the search. Here, we summarized the demographic, clinical characteristics, laboratory and diagnostic work-ups, and therapeutic management in these patients.

RESULTS

Among the 42 CD cases, the median age was 50 years (range 23-83), with a 2:1 female to male ratio. The majority of patients (88.1%) developed CC prior to CD diagnosis, while the remaining were previously diagnosed CD cases reporting low adherence to a gluten-free diet (GFD). Clinically, patients presented with severe diarrhea (all cases), weight loss (about two thirds) and, in particular situations, with neurologic (6 cases) or cardiovascular (1 case) manifestations or bleeding diathesis (4 cases). One in four patients had a precipitating factor that could have triggered the CC (e.g. trauma, surgery, infections). Laboratory workup of patients revealed a severe malabsorptive state with metabolic acidosis, dehydration, hypoalbuminemia and anemia. The evolution of GFD was favorable in all cases except one, in whom death was reported due to refeeding syndrome.

CONCLUSION

Celiac crisis is a rare but severe and potentially fatal clinical feature of CD. A high index of suspicion is needed to recognize this clinical entity and to deliver proper therapy consisting of supportive care and, subsequently, GFD.
