Compliant gluten-free children with celiac disease: an evaluation of psychological distress

Vulnerability in Children with Celiac Disease: Findings from a Scoping Review

(1) Background: The scientific literature highlights that children diagnosed with celiac disease (CD) are at a heightened risk of experiencing physical, psychological, and social challenges, impacting their overall healthy childhood development. However, there remains a lack of a clear understanding regarding the factors that contribute to this vulnerability. The purpose of this study is to analyze and map the evidence on the sociopsychosomatic vulnerability of these children and identify gaps in this topic. (2) Methods: Following Joanna Briggs Institute's guidelines for scoping reviews, we executed a detailed search of key electronic databases and explored the grey literature to capture a broad spectrum of studies. Our focus was on identifying research that looked into the multiple dimensions of vulnerability-physical, psychological, and social-in children with CD. We included a diverse range of study designs as well as systematic reviews, ensuring a comprehensive analysis. The selection process was stringent, utilizing clearly defined inclusion and exclusion criteria. (3) Results: We identified 61 studies that met our inclusion criteria. The review highlighted significant adverse health outcomes in children with CD and elucidated various individual and environmental determinants that influenced these vulnerabilities. It also underscored the lack of assessment tools to evaluate the risk of health problems in this population. (4) Conclusions: The findings underscore a critical need for further research to deepen our understanding of the vulnerabilities associated with CD in children. Developing targeted assessment tools will be crucial in stratifying health risks and enhancing care strategies for this vulnerable population.

Psychological, Psychiatric, and Organic Brain Manifestations of Celiac Disease

INTRODUCTION

Celiac disease is an autoimmune condition that affects approximately 1% of the population worldwide. Although its main impact often concerns the small intestine, resulting in villous atrophy and nutrient malabsorption, it can also cause systemic manifestations, particularly when undiagnosed or left untreated.

METHOD

Attention is directed to the possible psychological, psychiatric, and organic brain manifestations of celiac disease. Specific topics related to the influence and risk of such manifestations with respect to celiac disease are defined and discussed. Overall, eighteen main topics are considered, sifted from over 500 references.

RESULTS

The most often studied topics were found to be the effect on quality of life, organic brain dysfunction and ataxia, epilepsy, Down syndrome, generalized psychological disorders, eating dysfunction, depression, and schizophrenia. For most every topic, although many studies report a connection to celiac disease, there are often one or more contrary studies and opinions. A bibliographic analysis of the cited articles was also done. There has been a sharp increase in interest in this research since 1990. Recently published articles tend to receive more referencing, up to as many as 15 citations per year, suggesting an increasing impact of the topics. The number of manuscript pages per article has also tended to increase, up to as many as 12 pages. The impact factor of the publishing journal has remained level over the years.

CONCLUSION

This compendium may be useful in developing a consensus regarding psychological, psychiatric, and organic brain manifestations that can occur in celiac disease and for determining the best direction for ongoing research focus.

Dietary eating patterns, dairy consumption, and anxiety: A systematic literature review

BACKGROUND

Nutrition affects both physical and mental health but evidence is mixed regarding potential associations between anxiety and diet, particularly dairy consumption. We conducted a systematic literature review (SLR) of dairy consumption and/or various dietary patterns and risk of anxiety.

METHODS

Literature searches were conducted in PubMed and Embase. All study designs except case reports, small case series, and SLRs were considered for inclusion. Reference lists of previously published SLRs were reviewed for any relevant additional studies. Studies of populations without dairy sensitivities exploring the association between dietary patterns and/or dairy consumption and anxiety published through May 2022 were identified using predefined eligibility criteria. Study quality was determined using the Academy of Nutrition and Dietetics Quality Criteria Checklist.

RESULTS

For this SLR, 132 studies were included; 80 were cross-sectional. Studies examined different dietary patterns (e.g., Mediterranean, gluten-free) and anxiety using various anxiety scales, with 19 studies specifically reporting on whole dairy consumption and anxiety. Dairy consumption was significantly associated with a lower risk of anxiety in 7 studies, while the remaining 12 studies showed no significant associations. Evidence was mixed for the association between various dietary patterns and anxiety, but more studies observed a lower risk of anxiety with greater adherence to "healthy" diets (e.g., Mediterranean, diet quality score, vegetarian/vegan) than a higher risk. Notable heterogeneity in study populations, time periods, geographical locations, dietary assessment methods, and anxiety scales was observed.

CONCLUSIONS

The results of this SLR suggest a potential link between diet including diary consumption and anxiety, but future studies, especially with longitudinal designs that measure diet and anxiety at several timepoints and comprehensively adjust for confounders, are needed to fully understand the relationship between diet and anxiety.

A Clinical Investigation on ADHD-Traits in Childhood Celiac Disease

OBJECTIVE

There are no definitive results about either the presence of exact comorbidity between celiac disease (CD) and attention-deficit/hyperactivity disorders (ADHD) or etiology. We intend to screen ADHD-related cognitive and behavioral traits in children with biopsy-proven CD and investigate the possible association of these traits with certain vitamin levels, body-mass index, and gluten-free diet (GFD) compliance.

METHOD

A total of 85 children with biopsy-proven CD (the ages of 8-18 years) were compared with age and sex-matched 72 healthy controls in terms of demographics, psychiatric symptoms, certain vitamin levels, and anthropometric measurements.

RESULTS

ADHD-like cognitive issues, such as inattention and learning difficulties, as well as psychosomatic symptoms and poor prosocial behavior, were all associated with GFD noncompliance in childhood CD.

CONCLUSION

Untreated CD may predispose to ADHD-resembling symptoms. Physicians should be aware of the probability of ADHD misdiagnosing due to ADHD-resembling cognitive and behavioral traits in untreated CD.

Examining the Psychosocial Well-Being of Children and Adolescents With Coeliac Disease: A Systematic Review

This review aimed to synthesize the available literature regarding the psychosocial well-being of children and adolescents with coeliac disease (CD). Research on psychosocial well-being outcomes in children and adolescents with CD under the age of 18 were identified through a systematic search in the PsychInfo, Medline, Embase, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases in July 2021. Outcomes, including health-related quality of life (HRQOL), psychological adjustment, mental health, and social functioning were examined. Changes in outcomes over time and the geographic representation of the included studies were also analyzed. A total of 43 studies were included. Mixed results were found in the domain of HRQOL and mental health. Both challenges with psychological adjustment and adaptive coping strategies were identified. Social functioning was found to be an area of difficulty for children and adolescents with CD. However, there was high heterogeneity in methodology and participant characteristics between studies. This review concluded there were mixed findings regarding the HRQOL and mental health of young people with CD. However, CD and the gluten-free diet initiates a need for psychological adjustment and impacts on social functioning. The review highlights the need for the integration of physical and psychosocial care, and further research to determine the most appropriate screening measures, and the most efficacious psychological interventions for this group. Future research should continue examining changes in psychosocial outcomes over time given the increase in the availability of gluten-free foods and changes in food labeling policies.

"I sort of never felt like I should be worried about it or that I could be worried about it'" an interpretative phenomenological analysis of perceived barriers to disclosure by young people with coeliac disease

OBJECTIVES

There has been little research in the United Kingdom regarding young people's experiences of disclosure of psychological difficulties relating to coeliac disease (CD) to others, particularly healthcare professionals. This study sought to address this systematically with a focus on the lived experiences of young people with CD. This study aimed to gain insight into how paediatric gastroenterology services could improve the patient experience for those with CD and support the identification of patients who may benefit from further psychological support.

DESIGN

This study used interpretive phenomenological analysis (IPA) of patient accounts.

METHODS

Seven young people with CD (aged 11-16 years) were recruited from a UK hospital paediatric gastroenterology service. Semi-structured interviews were carried out and verbatim transcripts were analysed using IPA to explore young people's experiences of CD and why they might feel able or unable to disclose psychological difficulties associated with their condition to clinicians.

RESULTS

Three superordinate themes were interpreted from the data. The first encapsulated experiences of adjusting to the diagnosis within a developmental context, including the role of adults in information provision and the importance of peer support. The second outlined experiences of managing perceived or actual stigma regarding others' perceptions of the condition and themselves. The third incorporated perceived barriers to disclosure relating to power, safety, and beliefs about the role of medical professionals.

CONCLUSIONS

Findings highlight the importance of clinicians continually providing developmentally appropriate information to young people and actively breaking down barriers to disclosure through body language and the use of clear questions regarding emotional experiences.

Pandemic-Related Social Disruption and Well-Being in Pediatric Gastrointestinal Diseases

OBJECTIVE

The coronavirus disease 2019 (COVID-19) pandemic has impacted everyone, but there are few data regarding how the pandemic has influenced the lives of children with gastrointestinal (GI) conditions. This cross-sectional study assessed pandemic-related social disruption (PRSD) in children with inflammatory bowel disease (IBD), celiac disease (CD), and irritable bowel syndrome (IBS), and the potential buffering effect of the parent-child relationship.

METHODS

A survey completed between September and December 2020 asked 146 children (ages 8-17) diagnosed with IBD (n = 44), CD (n = 81), or IBS (n = 51) and 185 parents how the pandemic has contributed to social disruption (i.e., financial stability, COVID-19 exposure, school changes, GI needs, and isolation) and their social-emotional well-being. Structural equation modeling was used to examine the role of social disruption on well-being, and the moderating effect of the parent-child relationship.

RESULTS

Increased social disruption predicted worse parent, β = 0.24, p = .02, and child well-being, β = 0.38, p < .01. The parent-child relationship moderated the relationship between parent and child well-being, β = 0.21, p = .03. Strong parent-child relationships predicted a positive association between parent and child well-being, β = 0.23, p = .003, whereas medium, β = 0.09, p = .14, and poor, β = -0.06, p = .52, relationships did not.

CONCLUSIONS

PRSD negatively impacted the well-being of children with GI conditions, and the parent-child relationship moderated this relationship. These findings are relevant to pediatric psychologists treating the physical and mental health needs of children with GI conditions and their parents.

Anxiety and Depression in Pediatric Patients with Celiac Disease: A Large Cross-Sectional Study

Mental health is a growing concern in pediatric celiac disease (CD). This study utilized the Revised Children's Anxiety and Depression Scale (RCADS) to investigate anxiety and depression symptom rates. Participants were children ages 8 to 17 years (M = 11.7, SD = 2.7; N = 175) with biopsy-proven CD (Median = 1.1 years post-diagnosis, IQR = 0-4) categorized into groups based on the child's age, caregiver or child respondent, presence or absence of comorbidities, and gluten-free diet duration. Self-reported RCADS scores showed 39% of children having clinically significant concerns for anxiety or depression ( P < 0.0001) but only 7% of caregiver-proxy RCADS scores indicated significant concerns for the child's anxiety and 14% for the child's depression. Rates of child-reported anxiety and depression symptoms were significantly higher for those without medical comorbidities than those with ( P = 0.04). Therefore, screening for mental health concerns, particularly anxiety and depression, should be routinely performed in pediatric patients with CD.

Psychological Considerations in the Dietary Management of Patients With DGBI

In this article, an expert team of 2 gastro-psychologists, a dietician, and an academic gastroenterologist provides insights into the psychological and social implications of evidence-based and "popular" dietary interventions in disorders of gut-brain interaction (DGBI). We focus on practical approaches for evaluating a patient's appropriateness for a dietary intervention, considering the nutritional, psychological, behavioral, and social context in which a patient may find themselves managing their DGBI with dietary intervention. We also discuss how to identify risk factors for and symptoms of avoidant/restrictive food intake disorder, a growing concern in the DGBI population.

The Relationship between FFMQ Mindfulness and Harmony in Life among Patients with Celiac Disease

Background

Patients with Celiac Disease (CD) experience psychological disorders and emotion-regulation disruptions. Although following a gluten-free diet alleviates their symptoms, these patients report social relationship problems.

Objective

The first aim of this study was to analyze the level of FFMQ mindfulness (describing emotions, acting with awareness, observing, non-judging of inner experience, and non-reactivity to inner experience) and harmony in life (HiL) in patients with CD. The second goal was to examine the relationship between the FFMQ and HiL scales in patients with CD. The third was to detect the effects of the duration of the illness, education level, and employment status on FFMQ-measured mindfulness and HiL.

Design

The study involved 111 Turkish patients with CD (N Females = 75, 67.6%) living in Turkey. The patients filled out the FFMQ and HiL questionnaires via a google form survey. The duration of their diagnosis, age, employment status, and education level were nominal variables. A Pearsons' correlation test, independent t-test, multiple linear regression, and one-way ANO VA were implemented.

Results

The results showed that patients with CD had a low level of HiL. The total FFMQ score was positively related to the HiL scale. Education and duration of diagnosis had a significant impact on the FFMQ and HiL scores. Age affected the level of describing emotions, and employment status had a strong effect on acting with awareness. However, gender affected neither the FFMQ nor HiL levels.

Conclusion

The results showed that patients with CD expressed a low level of HiL. Non-reactivity to inner experience, observing, and acting with awareness were positive predictors of the HiL scores. Moreover, since the HiL and FFMQ scales showed high internal consistency, the FFMQ and HiL questionnaires can be used in further studies of patients with CD.

Association Between Celiac Disease and Autism Spectrum Disorder: A Systematic Review

OBJECTIVE

The aim of the study was to perform a systematic review assessing the research investigating the association between celiac disease (CD) and autism spectrum disorder (ASD).

METHODS

A literature search of MEDLINE and EMBASE was performed without limits placed on year or language. Observational studies reporting on the occurrence of CD among patients with ASD and/or the occurrence of ASD among patients with CD were included. Study design, characteristics, diagnostic criteria for ASD and CD, and the frequency of positive cases in the studied sample were recorded. Study quality was assessed using an adapted Newcastle-Ottawa Quality Assessment Scale. Due to substantial heterogeneity between studies, a meta-analysis was not performed.

RESULTS

Of the 298 unique citations identified within our search strategy, 17 articles evaluating the association between CD and ASD were included. Of those articles, 13 observed samples of patients with ASD, and 6 observed samples of patients with CD. Overall, most studies had small sample sizes and reported no evidence for an association between the 2 conditions. However, a limited number of population-based studies of higher quality suggested a potential association between CD and ASD.

CONCLUSIONS

Most studies assessing an association between CD and ASD are at risk for systematic and/or random error. A potential link has, however, been shown in a handful of high-quality studies, and, therefore, this comorbidity cannot be ruled out. Future studies should recruit larger sample sizes, include precise definitions of CD and ASD, and exclude patients with ASD on a gluten-free diet.

Dietary gluten avoidance in Canada: a cross-sectional study using survey data

BACKGROUND

A gluten-free diet (GFD) is required for the management of some conditions, whereas some Canadians may follow a GFD for discretionary reasons. We sought to estimate the prevalence of Canadians who adhere to a GFD, identify factors associated with adherence to a GFD, and describe and compare the location of food preparation and consumption for those who follow a GFD, those who report no dietary avoidances and those reporting other dietary avoidances.

METHODS

We used cross-sectional data from the 2015 Canadian Community Health Survey - Nutrition (n = 20 487). Demographic variables included sex, age group, ethnicity, highest level of household education and income adequacy. The relations between respondent characteristics and report of a GFD were estimated using logistic regression. Respondents were further categorized as avoiding dietary gluten, other dietary avoidances and no dietary avoidances.

RESULTS

An estimated 1.9% of Canadians follow a GFD. Women had 2 times higher odds (odds ratio [OR] 2.08, 95% confidence interval [CI] 1.32 to 3.27) of reporting a GFD than men. After adjustment for income adequacy, household education, sex, age group and ethnicity, residents of Ontario and Quebec had about half the odds (OR 0.52, 95% CI 0.31 to 0.87, and OR 0.55, 95% CI 0.32 to 0.94, respectively) of reporting a GFD compared with residents of Atlantic Canada. Canadians who followed a GFD consumed significantly fewer calories from foods prepared at restaurants than both Canadians who reported no dietary avoidances and those who reported dietary avoidances other than gluten. Canadians following a GFD reported that 2.0% (95% CI 1.1% to 2.9%) of their daily kilocalories were from foods prepared at restaurants, compared with 6.7% (95% CI 5.4% to 7.9%) for Canadians reporting 1 or more dietary avoidances other than gluten, and 6.4% (95% CI 6.0% to 6.9%) for those reporting no avoidances.

INTERPRETATION

The estimated 1.9% prevalence of dietary gluten avoidance likely includes individuals with celiac disease, wheat allergies and nonceliac gluten sensitivity, as well as individuals excluding gluten in the management of irritable bowel syndrome or for reasons related to dietary trends. Canadians eating GFDs consume fewer daily calories from restaurant-prepared foods than other Canadians, which may have social implications.

Gluten and Autism Spectrum Disorder

An expanding body of literature is examining connections between Autism Spectrum Disorder (ASD) and dietary interventions. While a number of specialist diets have been suggested as beneficial in ASD, gluten has received particularly close attention as a potentially exacerbating factor. Reports exist suggesting a beneficial effect of the gluten-free diet (GFD) in ameliorating behavioural and intellectual problems associated with ASD, while epidemiological research has also shown a comorbidity between ASD and coeliac disease. However, both caregivers and clinicians have expressed an uncertainty of the value of people with ASD going gluten-free, and as the GFD otherwise receives considerable public attention a discussion which focuses specifically on the interaction between ASD and gluten is warranted. In this review we discuss the historical context of ASD and gluten-related studies, and expand this to include an overview of epidemiological links, hypotheses of shared pathological mechanisms, and ultimately the evidence around the use and adoption of the GFD in people with ASD.

Evaluation of Daily Lives of Children and Adolescents with Celiac Disease and Nursing Approaches

The incidence of celiac disease has been increasing in recent years. Celiac disease is an autoimmune enteropathy that emerges mostly in the childhood period. This disorder is a chronic condition of the small intestine due to gluten intake in individuals with genetic predisposition. In the treatment of celiac disease, gluten-free diet therapy is applied. However, the adaptation process to the diet may create difficulties for patients. Compliance with diet is much more difficult among patients with celiac disease in childhood and adolescence than in adult patients. Children and adolescents face distinct difficulties in their homes, at school, and in their social lives. Besides following dietary treatment, children and adolescents living with celiac disease need peer support to manage their daily routines. In this article, we aimed to discuss the problems experienced by children and adolescents living with celiac disease and nursing approaches to these problems.

Child and Parent Mental Health Problems in Pediatric Celiac Disease: A Prospective Study

OBJECTIVES

The aim of our study was to estimate the levels of mental health problems in children with celiac disease (CD) along with their parents' mental health status, to compare these levels with those of healthy controls and to investigate how these problems are affected by a gluten-free diet (GFD).

METHODS

Our study constituted 50 patients with CD at diagnosis before the initiation of a GFD (age 8.6 ± 3.7 years, group A), 39 patients with CD on a GFD for at least 12 months (age 10.4 ± 3.4 years, group B) and 38 healthy controls (age 7.7 ± 3.8 years, group C), as well as their parents. One of the parents of each child completed the Child Behaviour Checklist (CBCL) and the Symptom Checklist 90 (SCL-90-R) to evaluate the children's and parents' mental health problems, respectively. Twenty patients in group A were reevaluated at least 12 months after initiation of a GFD (group D).

RESULTS

At diagnosis, CD patients had higher scores in the CBCL for internalizing problems than healthy controls (55.7 ± 10.3 vs 47.9 ± 15.4, P = 0.007) and their parents demonstrated increased severity of mental health problems, including anxiety and depression, than the parents of healthy controls (0.72 ± 0.49 vs 0.54 ± 0.58, P = 0.013).

CONCLUSIONS

CD patients at diagnosis and their parents, had more mental health problems, including anxiety and depression, than healthy controls.

Mental Health Disorders and Psychosocial Distress in Pediatric Celiac Disease

OBJECTIVES

Celiac disease (CeD) has been associated with increased mental health disorders (MHD) and psychosocial distress in children, which may complicate treatment with the gluten-free diet (GFD). This single-center cross-sectional study examined psychological comorbidities in children with CeD to assess psychological needs in CeD care.

METHODS

Participants were 73 parents (95% mothers) of children (ages 3-18) attending a multidisciplinary celiac disease clinic. Parents completed electronic surveys about their child's MHD history, psychological symptoms, and GFD experiences. Rates of MHD were calculated and compared with National Institute of Mental Health population-level data. Differences in psychosocial symptoms and GFD experiences were examined based on child age, time since CeD diagnosis, and MHD.

RESULTS

Thirty-four percentage of children had at least 1 MHD; anxiety disorders (16%, P < 0.001) and attention-deficit/hyperactivity disorder (ADHD; 16%, P = 0.01) were more common than general population rates. More than 1 quarter of parents reported current child psychosocial distress (28%-39%), and approximately half reported parent stress (51%) and financial burden (46%) associated with the GFD. Parents of children with new CeD diagnoses reported lower confidence in the GFD (P < 0.01) but MHD, stress, and financial burden did not differ by time since CeD diagnosis. Children with MHD had more anxiety, anger, overall distress, and parent distress than those without MHD (Ps < .05).

CONCLUSIONS

Comorbid CeD and MHD was common and was associated with increased child and parent psychosocial distress. Our findings emphasize the importance of psychological screening and services to assess for and treat comorbid MHD and to mitigate psychosocial distress associated with the GFD.

Nutrition Assessment, Interventions, and Monitoring for Patients with Celiac Disease: An Evidence Analysis Center Scoping Review

The objectives of this scoping review were to identify and characterize studies examining nutrition assessment, interventions, and measures to monitor gluten-free diet (GFD) adherence/compliance in patients with celiac disease (CD). An electronic literature search of four databases (Cochrane Database for systematic reviews, CINAHL, Embase, and Ovid MEDLINE) was conducted to identify articles examining nutrition care in CD individuals. Except for narrative review, grey literature, and case study/report, all types of peer-reviewed articles published between January 2007 and August 2018 were eligible. There were a total of 10,823 records; 10,368 were excluded during the first round of screening due to irrelevancy and/or duplication. Of the 455 full-text articles that were assessed, 292 met the criteria and were included. Most of the studies were observational studies (n=212), followed by experimental trials (n=50), evidence-based practice guideline (EBPG)/report/statement (n=16), and systematic review (SR) (n=14). Nine original studies examined assessment, focusing mainly on different tools/ways to assess GFD adherence. The majority of the included original articles (n=235) were in the nutrition intervention category with GFD, oats, and prebiotics/probiotics as the top-three most studied interventions. There were eight SRs on GFD and five on oats. One SR and 21 original studies investigated the effectiveness of different measures to monitor GFD adherence/compliance. Although recent CD EBPGs were identified, different methods with varying levels of rigor, in terms of literature search and assessment of evidence strength, were used. Based on this scoping review, interventions focused on gluten-free diet and oats have been significantly covered by either SRs or EBPGs. Studies related to prebiotics/probiotics and education program/counseling focused interventions, as well as assessment, in CD patients have increased in recent years. Thus, it might be beneficial to conduct SRs/EBPGs focused on these topics to guide practitioners.

Psychiatric Manifestations of Coeliac Disease, a Systematic Review and Meta-Analysis

Background: Coeliac disease (CD) is increasingly prevalent and is associated with both gastrointestinal (GI) and extra-intestinal manifestations. Psychiatric disorders are amongst extra-intestinal manifestations proposed. The relationship between CD and such psychiatric disorders is not well recognised or understood. Aim: The aim of this systematic review and meta-analysis was to provide a greater understanding of the existing evidence and theories surrounding psychiatric manifestations of CD. Methodology: An online literature search using PubMed was conducted, the prevalence data for both CD and psychiatric disorders was extracted from eligible articles. Meta analyses on odds ratios were also performed. Results: A total of 37 articles were included in this review. A significant increase in risk was detected for autistic spectrum disorder (OR 1.53, 95% CI 1.24–1.88, p < 0.0001), attention deficit hyperactivity disorder (OR 1.39, 95% CI 1.18–1.63, p < 0.0001), depression (OR 2.17, 95% CI 2.17–11.15, p < 0.0001), anxiety (OR 6.03, 95% CI 2.22–16.35, p < 0.0001), and eating disorders (OR 1.62, 95% CI 1.37–1.91, p < 0.00001) amongst the CD population compared to healthy controls. No significant differences were found for bipolar disorder (OR 2.35, 95% CI 2.29–19.21, p = 0.43) or schizophrenia (OR 0.46, 95% CI 0.02–10.18, p = 0.62). Conclusion: CD is associated with an increased risk of depression, anxiety, eating disorders as well as ASD and ADHD. More research is required to investigate specific biological explanations as well as any effect of gluten free diet.

Psychological Comorbidities in Childhood Celiac Disease: A Systematic Review

OBJECTIVES

Mental health disorders comorbid to chronic illness are associated with higher medical care utilization and costs for adults and children. Celiac disease (CD) has a substantial perceived treatment burden and is associated with higher rates of psychopathology in adults. However, establishing the risk for psychological comorbidities in children with CD is still needed. This study aimed to review existing research on mental health concerns in pediatric CD and propose an initial psychosocial research and clinical agenda.

METHODS

Databases, including Scopus and PubMed. Additional publications were accessed and reviewed from the references provided by initially identified publications. Two investigators screened studies using predetermined criteria (peer-reviewed, published in English, electronically available, inclusive of child participants, and examining CD). One investigator initially extracted data, with subsequent review by the second investigator.

RESULTS

Twenty-six publications met criteria for the current review (16 case-control, 9 observational, and 1 clinical trial). Publications were heterogeneous in symptoms examined, methodology, and population characteristics. Several studies found elevated risk for psychological comorbidities and poorer quality of life in children with CD. However, many studies were limited by small sample sizes and inconsistent or nonvalidated approaches to measuring psychological symptoms.

CONCLUSIONS

Many existing studies have found increased prevalence of comorbid CD and psychological symptoms or diagnoses. Therefore, screening for psychological symptoms in CD and also screening for CD in psychological clinic populations is needed. We have identified the importance for further study of mechanisms and risk, and identify preliminary priorities for psychosocial research and clinical care in pediatric CD.

Bidirectional relationship between eating disorders and autoimmune diseases

BACKGROUND

Immune system dysfunction may be associated with eating disorders (ED) and could have implications for detection, risk assessment, and treatment of both autoimmune diseases and EDs. However, questions regarding the nature of the relationship between these two disease entities remain. We evaluated the strength of associations for the bidirectional relationships between EDs and autoimmune diseases.

METHODS

In this nationwide population-based study, Swedish registers were linked to establish a cohort of more than 2.5 million individuals born in Sweden between January 1, 1979 and December 31, 2005 and followed up until December 2013. Cox proportional hazard regression models were used to investigate: (a) subsequent risk of EDs in individuals with autoimmune diseases; and (b) subsequent risk of autoimmune diseases in individuals with EDs.

RESULTS

We observed a strong, bidirectional relationship between the two illness classes indicating that diagnosis in one illness class increased the risk of the other. In women, the diagnoses of autoimmune disease increased subsequent hazards of anorexia nervosa (AN), bulimia nervosa (BN), and other eating disorders (OED). Similarly, AN, BN, and OED increased subsequent hazards of autoimmune diseases.Gastrointestinal-related autoimmune diseases such as, celiac disease and Crohn's disease showed a bidirectional relationship with AN and OED. Psoriasis showed a bidirectional relationship with OED. The previous occurence of type 1 diabetes increased the risk for AN, BN, and OED. In men, we did not observe a bidirectional pattern, but prior autoimmune arthritis increased the risk for OED.

CONCLUSIONS

The interactions between EDs and autoimmune diseases support the previously reported associations. The bidirectional risk pattern observed in women suggests either a shared mechanism or a third mediating variable contributing to the association of these illnesses.

Quality of Life in People with Coeliac Disease: Psychological and Socio- Economic Aspects

BACKGROUND AND OBJECTIVE

Coeliac disease (CD) is a chronic autoimmune intestinal disorder characterized by intolerance to gluten, a protein contained in certain cereals. The main physiopathological basis of CD is the progressive destruction of intestinal villi caused by gluten ingestion by genetically-susceptible individuals. Patients who receive a diagnosis of CD must make significant changes to their daily habits and this can affect their quality of life. The objective of this review is to summarize the evidence regarding the economic, physical and social limitations which can affect the quality of life in patients with CD.

RESULTS

Different factors such as physical changes, psychological effects, interpersonal relationships, emotions and economic difficulties can affect the quality of life of these patients. Observations suggest that, in general, women with CD experience a greater deterioration in their quality of life than men. Lastly, complications in daily life are also associated with the reduced availability of gluten-free products which also usually cost more than standard products.

CONCLUSIONS

Continuous health education and care regarding socio-economic issues should be continuously developed and provided to people with CD.

Diminished quality of life among adolescents with coeliac disease using maladaptive eating behaviours to manage a gluten-free diet: a cross-sectional, mixed-methods study

BACKGROUND

Certain approaches to managing a strict gluten-free diet (GFD) for coeliac disease (CD) may lead to impaired psychosocial well-being, a diminished quality of life (QOL) and disordered eating. The present study aimed to understand adolescents' approaches to managing a GFD and the association with QOL.

METHODS

Thirty adolescents with CD (13-17 years old) following the GFD for at least 1 year completed the Celiac Dietary Adherence Test (CDAT) and QOL survey. Their approaches to GFD management were explored using a semi-structured interview, where key themes were developed using an iterative process, and further analysed using a psychosocial rubric to classify management strategies and QOL. CDAT ratings were compared across groups.

RESULTS

Gluten-free diet management strategies were classified on a four-point scale. Adaptive eating behaviours were characterised by greater flexibility (versus rigidity), trust (versus avoidance), confidence (versus controlling behaviour) and awareness (versus preoccupation) with respect to maintaining a GFD. Approximately half the sample (53.3%) expressed more maladaptive approaches to maintaining a GFD and those who did so were older with lower CD-Specific Pediatric Quality of Life (CDPQOL) scores, mean subscale differences ranging from 15.0 points for Isolation (t = 2.4, P = 0.03, d.f. = 28) to 23.4 points for Limitations (t = 3.0, P = 0.01, d.f. = 28).

CONCLUSIONS

Adolescents with CD who manage a GFD with maladaptive eating behaviours similar to known risk factors for feeding and eating disorders experience diminished QOL. In accordance with CD management recommendations, we recommend ongoing follow-up with gastroenterologists and dietitians and psychosocial support referrals, as needed.

Assessment of Quality of Life, Anxiety and Depressive Symptoms in Serbian Children with Celiac Disease and their Parents

OBJECTIVES

To evaluate the level of health-related quality of life (QoL) and presence of anxiety and depressive symptoms in Serbian children with celiac disease from the perspective of patients and their parents.

METHODS

This cross-sectional study investigated the group of children and adolescents with celiac disease aged 5-18 y, and at least one parent of each patient with celiac disease. The patients and their parents were recruited at the Institute of Mother and Child Health of Serbia and the University Children's Hospital in Belgrade. The instruments used in this study were child-self and parent-proxy versions of the Pediatric Quality of Life Inventory (PedsQL), Screen for Child Anxiety Related Emotional Disorder (SCARED) and Short Mood and Feelings Questionnaire (MFQ). Additional information was collected from the medical records of each patient.

RESULTS

According to the PedsQL questionnaire, the quality of life was similarly assessed by both parents and their children (p > 0.05), as well as the presence of depressive symptoms according to MFQ questionnaire. However, a statistically significant difference was observed in the total score of the SCARED questionnaire for children and parents [total score (p < 0.05), panic-somatic disturbance (p < 0.01) and social anxiety (p < 0.01)].

CONCLUSIONS

The patients and their parents in Serbia have similarly assessed the quality of life of children with celiac disease, but the differences in the scores of SCARED questionnaire indicate that it is necessary to include both children and parents in the assessment of QOL.

Navigating the Gluten-Free Boom: The Dark Side of Gluten Free Diet

In gluten dependent conditions the gluten free diet is the cornerstone of therapy, decreasing disease activity, improving health and quality of life and treating or preventing the associated complications. Gluten withdrawal implies strict and lifelong elimination not only of wheat, barley, rye, and wheat-contaminated oats, but also of numerous non-nutritional products where components of wheat are often added. Due to multiple reasons the diet is difficult to follow and the long-term adherence is decreased with time. The present review summarizes the dark side of gluten restriction where nutritional deficiencies, toxicity, morbidity, mortality, and mental health problems are reported. The aim being to increase awareness, avoid, detect and treat the side effects and to promote a healthier nutrition, for the patient's benefits.

Adherence to Gluten-Free Diet in Children with Celiac Disease

Celiac disease (CD) can only be treated by rigorous life-long gluten-free diet (GFD). The study included 102 mothers and their CD children treated with GFD for at least two years. Frequency and cause of diet failure in children treated at present (54 children) and 10 years ago (48 children) were compared. Dietary adherence was evaluated serologically (tTG), while diet management difficulties were examined by means of a questionnaire. The study shows that one-third of patients fail to follow GFD, more often 10 years ago than now (40% vs. 26%; p < 0.05), mainly children aged 13⁻18 (54% vs. 40% now; p < 0.05). Younger children (up to 12) are less likely to abandon the diet (27% vs. 8%; p < 0.05). In this age group non-intentional diet failure prevails, while teenagers interrupt their diet intentionally (45% vs. 33%; p = ns (small population of children in this groups)). Currently, the most common causes of teenage diet failure are the absence of symptoms after consuming a small amount of gluten and, even more often, troublesome diet administration. Previously, the absence of peer acceptance prevailed. With this study we found that: 1. In West Pomerania, every fourth CD child does not follow GFD. 2. For years, teenagers have failed to follow GFD due to the absence of symptoms after consuming small amounts of gluten. 3. The incidence of non-intentional failure to follow GFD has significantly decreased over years, which indicates better dietary care.

Psychiatric Comorbidity in Children and Adults with Gluten-Related Disorders: A Narrative Review

Gluten-related disorders are characterized by both intestinal and extraintestinal manifestations. Previous studies have suggested an association between gluten-related disorder and psychiatric comorbidities. The objective of our current review is to provide a comprehensive review of this association in children and adults. A systematic literature search using MEDLINE, Embase and PsycINFO from inception to 2018 using terms of ‘celiac disease’ or ‘gluten-sensitivity-related disorders’ combined with terms of ‘mental disorders’ was conducted. A total of 47 articles were included in our review, of which 28 studies were conducted in adults, 11 studies in children and eight studies included both children and adults. The majority of studies were conducted in celiac disease, two studies in non-celiac gluten sensitivity and none in wheat allergy. Enough evidence is currently available supporting the association of celiac disease with depression and, to a lesser extent, with eating disorders. Further investigation is warranted to evaluate the association suggested with other psychiatric disorders. In conclusion, routine surveillance of potential psychiatric manifestations in children and adults with gluten-related disorders should be carried out by the attending physician.

Are children with chronic illnesses requiring dietary therapy at risk for disordered eating or eating disorders? A systematic review

OBJECTIVE

Pediatric chronic illnesses (CI) can affect a child's mental health. Chronic illnesses with treatment regimens that specify a therapeutic diet may place the child at increased risk for disordered eating and specific eating disorders (ED). The aim of this review is to examine the relation between diet-treated CI and disordered eating and to determine the order of onset to infer directionality. Diet-treated CI is hypothesized to precede and to be associated with disordered eating.

METHOD

A comprehensive search of empirical articles that examine the relation between diet-treated CI (diabetes, cystic fibrosis, celiac disease, gastrointestinal disorders, and inflammatory bowel diseases) and disordered eating was conducted in Medline and PsycINFO using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A table of the sample's characteristics, ED measures, major pertinent findings, and the onset of CI in relation to ED were provided.

RESULTS

Diet-treated CI was associated with disordered eating and ED. Diet-treated CI had onset prior to disordered eating in most studies, except for inflammatory bowel diseases. Disordered eating and unhealthy weight management practices put children at risk for poor medical outcomes.

DISCUSSION

Interventions for diet-treated CI require a focus on diet and weight, but may increase the risk for disordered eating. Future research is needed to elucidate the mechanisms that transform standard treatment practices into pathological eating, including characteristics and behaviors of the child, parents/care providers, family, and treatment providers.

Celiac Disease Is Associated with Childhood Psychiatric Disorders: A Population-Based Study

OBJECTIVES

To determine the risk of future childhood psychiatric disorders in celiac disease, assess the association between previous psychiatric disorders and celiac disease in children, and investigate the risk of childhood psychiatric disorders in siblings of celiac disease probands.

STUDY DESIGN

This was a nationwide registry-based matched cohort study in Sweden with 10 903 children (aged <18 years) with celiac disease and 12 710 of their siblings. We assessed the risk of childhood psychiatric disorders (any psychiatric disorder, psychotic disorder, mood disorder, anxiety disorder, eating disorder, psychoactive substance misuse, behavioral disorder, attention-deficit hyperactivity disorder [ADHD], autism spectrum disorder [ASD], and intellectual disability). HRs of future psychiatric disorders in children with celiac disease and their siblings was estimated by Cox regression. The association between previous diagnosis of a psychiatric disorder and current celiac disease was assessed using logistic regression.

RESULTS

Compared with the general population, children with celiac disease had a 1.4-fold greater risk of future psychiatric disorders. Childhood celiac disease was identified as a risk factor for mood disorders, anxiety disorders, eating disorders, behavioral disorders, ADHD, ASD, and intellectual disability. In addition, a previous diagnosis of a mood, eating, or behavioral disorder was more common before the diagnosis of celiac disease. In contrast, siblings of celiac disease probands were at no increased risk of any of the investigated psychiatric disorders.

CONCLUSIONS

Children with celiac disease are at increased risk for most psychiatric disorders, apparently owing to the biological and/or psychological effects of celiac disease.

Coeliac disease in adolescence: Coping strategies and personality factors affecting compliance with gluten-free diet

OBJECTIVES

Patients suffering from a chronic condition such as coeliac disease (CD) need to develop coping strategies in order to preserve emotional balance and psychosocial functioning while adhering to their obligatory life-long gluten free diet (GFD). However, this can be particularly challenging for adolescents and may lead to dietary transgressions. Little is currently known about the influence of coping strategies and personality factors on dietary compliance. This study aims to explore these factors for the first time in adolescents with biopsy-proven CD.

STUDY DESIGN

We included 281 adolescents with CD and 95 healthy controls. We classified patients according to their GFD adherence status (adherent vs. non-adherent) and assessed coping strategies using the KIDCOPE and personality traits using the Junior-Temperament and Character Inventory (J-TCI).

RESULTS

Adolescents with CD adherent to GFD used less emotional regulation and distraction as coping strategies than non-adherent patients. In terms of personality traits, adherent patients differed from non-adherent patients with respect to temperament, but not with respect to character, showing lower scores in novelty seeking, impulsivity and rule transgressions and higher scores in eagerness with work and perfectionism compared to non-adherent patients. No differences were found between healthy controls and adherent CD patients across these personality traits.

CONCLUSIONS

Coping strategies and personality traits differ in adolescent patients with CD adherent to GFD from those not adherent, and may therefore relate to risk or protective factors in adherence. Targeting coping and temperament using psychological interventions may therefore be beneficial to support adolescents with CD and optimise their adherence to GFD.

Risks of hospitalization and drug consumption in children and young adults with diagnosed celiac disease and the role of maternal education: a population-based matched birth cohort study

BACKGROUND

Celiac disease (CD) may affect healthcare use in children and young adults. Socio-economic factors may act as a confounder or effect modifier. We assessed such hypotheses in a population-based birth cohort of young celiac subjects and references matched by maternal education.

METHODS

The cohort included all newborns recorded in the Medical Birth Register of Friuli-Venezia Giulia Region (Italy) between 1989 and 2011. CD incident cases were identified through pathology reports, hospital discharges and copayment exemptions and matched with up to five references by sex, year of birth and maternal education. Cox regression models were used to estimate Hazard Ratios (HRs) for major causes of inpatient diagnosis and drug prescription occurring after diagnosis in CD patients compared to references, stratifying by time of first event and maternal education.

RESULTS

We identified 1294 CD cases and 5681 references. CD cases had a higher risk of hospital admission for any cause (HR: 2.34; 95 % CI 2.08-2.63) and for all major ICD9-CM categories except obstetric complications, skin and musculoskeletal diseases, and injuries and poisoning. Prescription of all major ATC drug categories, except dermatologicals and genito-urinary medications, was significantly increased in CD subjects. For most outcomes, HRs were highest in the first year after CD diagnosis but remained significant after five or more years. HRs were similar across different categories of maternal education.

CONCLUSIONS

Diagnosed CD subjects had a higher risk of hospitalization and medication use compared to the general population, even five or more years after diagnosis, with no effect modification of maternal education.

Eating Disorders in Adolescents with Celiac Disease: Influence of Personality Characteristics and Coping

OBJECTIVES

Patients suffering from celiac disease (CD) have a higher risk of developing disturbed eating behaviour.

METHOD

In a multi-centre study, 259 female adolescents with CD and without a chronic condition were analysed regarding their eating disorder (ED) status, depression, personality, coping strategies and quality of life.

RESULTS

Patients with CD and comorbid EDs were older and more often non-compliant with their diet and had a higher body mass index (BMI) and higher levels of depression. Differences in personality features disappear when controlling for age and depression. Higher ill-being and lower joy in life were reported by patients with CD and ED compared with patients without EDs, even when controlling for age and depression levels. No differences between patients (with CD) with and without EDs in coping strategies were found. BMI and lower self-directedness predicted ED status.

CONCLUSIONS

Early identification of EDs in patients with CD is suggested and should include BMI and personality factors.

Primary care management of celiac disease

: Celiac disease is an autoimmune disorder with genetic predisposition that affects as many as 1 in 100 individuals. Treatment is a lifelong, strict adherence to a gluten-free diet. Management by a primary care provider may lead to increased adherence and can minimize effects of nonadherence to the diet.

Predictors of Compliance to Gluten-Free Diet in Children with Celiac Disease

Aim. To identify the predictors of compliance to gluten free diet in children with celiac disease. Methods. 134 children in the study group were assessed for dietary compliance followed by a questionnaire based interview. Psychosocial parameters were assessed by standard Pediatric Symptom Checklist (PSC). Dietary compliant and noncompliant groups were compared and assessed for factors affecting the dietary compliance. Predictability of all of these factors was assessed using binary logistic regression analysis with backward elimination to find out the best predictors of compliance. Results. In the study group, 88 (65.67%) were found to be strictly compliant. Factors that were found to be significantly associated with compliance were age at presentation, nuclear families, mother's education, and parents having better knowledge of celiac disease. Parents' and child's attitude towards his having to follow a restrictive diet and child's feelings were also shown to be significantly associated with compliance. Binary logistic regression analysis with backward elimination demonstrated that age at presentation, family type, child's attitude, and child's behaviour made a significant contribution to prediction. Conclusions. These results will contribute to the current body of research by providing health care practitioners with a framework for better dietary instruction to ensure maximum adherence to GFD.

Paediatric non-alcoholic Fatty liver disease: impact on patients and mothers' quality of life

BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) is one of the causes of fatty liver in adults and is currently the primary form of chronic liver disease in children and adolescents. However, the psychological outcome (i.e. the behavioural problems that can in turn be related to psychiatric conditions, like anxiety and mood disorders, or lower quality of life) in children and adolescents suffering of NAFLD has not been extensively explored in the literature.

OBJECTIVES

The present study aims at evaluating the emotional and behavioural profile in children suffering from NAFLD and the quality of life in their mothers.

PATIENTS AND METHODS

A total of 57 children (18 females/39 males) with NAFLD were compared to 39 age-matched control children (25 females/14 males). All participants were submitted to the following psychological tools to assess behavior, mood, and anxiety: the Multidimensional Anxiety Scale for Children (MASC), the Child Behavior Checklist (CBCL), and the Children's Depression Inventory (CDI). Moreover, the mothers of 40 NAFLD and 39 control children completed the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire.

RESULTS

NAFLD children scored significantly higher as compared to control children in MASC (P = 0.001) and CDI total (P < 0.001) scales. The CBCL also revealed significantly higher scores for NAFLD children in total problems (P = 0.046), internalizing symptoms (P = 0.000) and somatic complaints (P < 0.001). The WHOQOL-BREF revealed significantly lower scores for the mothers of NAFLD children in the overall perception of the quality of life (P < 0.001), and in the "relationships" domain (P = 0.023).

CONCLUSIONS

Increased emotional and behavioural problems were detected in children with NAFLD as compared to healthy control children, together with an overall decrease in their mothers' quality of life. These results support the idea that these patients may benefit from a psychological intervention, ideally involving both children and parents, whose quality of life is likely negatively affected by this disease.

Abdominal pain and functional gastrointestinal disorders in children with celiac disease

OBJECTIVE

To assess whether patients with celiac disease (CD) are more likely than controls to develop abdominal pain (AP) and AP-associated functional gastrointestinal disorders (FGID) in long-term follow-up.

STUDY DESIGN

In a retrospective study, data on children (3-22 years old) with CD diagnosed between 2000 and 2010 were obtained. Parents were contacted by telephone at least 6 months after the diagnosis of CD and invited to participate in the study. Consenting parents completed: (1) a telephone questionnaire on the presence of gastrointestinal symptoms; and (2) the parent report version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III for cases and selected controls.

RESULTS

Forty-nine cases (mean 11.3 years, 20 male participants) and 48 controls (mean 11.1 years, 24 male participants) were enrolled. Twelve children in the CD group (24.5%) and 7 children in the control group (14.6%) had AP at the time of the study (P = .3). Nine children in the CD group (18.3%) and 4 children in the control group (8.3%) met criteria for an AP-associated FGID according to the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III (P = .23).

CONCLUSION

It was found that children with CD and controls have a similar risk of AP and AP-FGIDs. Methodologic limitations prevent generalization of results, but large prospective studies should confirm the findings.

Quality of life and anxiety in adolescents with differentiated thyroid cancer

CONTEXT

Adolescents with differentiated thyroid cancer (DTC) require lifelong monitoring with a high possibility of reoperation or radioactive iodine. Although adult DTC survivors have similar or slightly worse quality of life (QOL), this has not been evaluated in the pediatric population.

OBJECTIVE

Our objective was to compare QOL and anxiety in adolescents with DTC to patients with acquired autoimmune hypothyroidism.

DESIGN, SETTING, AND PATIENTS

In this cross-sectional pilot study, three validated questionnaires were administered to 16 adolescents with DTC and 16 controls for assessment of QOL and anxiety levels. These included teen and parent PedsQL, Multidimensional Anxiety Scale for Children, and Coddington Life Events Scales for Adolescents. The contribution of age, time since diagnosis, and biochemical variables were compared with the outcome measures.

RESULTS

There were 16 DTC patients (seven males); 13 had papillary carcinoma, one had follicular carcinoma, and two had mixed type. At diagnosis, five DTC patients had lymph node involvement and two had lung metastases, although at time of assessment, only one DTC patient had lymph node involvement. DTC patients were older than control subjects (P=0.004) and had lower TSH levels than control subjects at time of assessment (P=0.013). QOL and anxiety levels did not differ between DTC patients compared with control subjects and with previously reported scores in a healthy cohort. QOL and anxiety level parameters were not influenced by age, time since diagnosis, or free T4 levels measured at the time of assessment.

CONCLUSIONS

Adolescents with DTC have similar QOL and anxiety levels compared with autoimmune hypothyroidism patients and with a healthy normative population.

The bowel and migraine: update on celiac disease and irritable bowel syndrome

This article explores possible relationships between migraine, irritable bowel syndrome (IBS), celiac disease (CD), and gluten sensitivity. These seemingly distinct medical entities curiously share many common epidemiological, psychosocial, and pathophysiological similarities. Considerable evidence is emerging to support a concept that experiencing significant threatening adverse events creates a state of hypervigilance in the nervous system, which associates with exaggerated response to future threats and episodic attacks of migraine and IBS. While this sensitizing response is generally considered to reside in the central nervous system, it may be possible that the initiation resides in the enteric nervous system as well. What appears to link migraine, IBS, and CD is a disease model of a genetically sensitive nervous system transformed into one that is hypervigilant, and that over time can often develop disabling and pervasive disease.

Health-related quality of life in children and adolescents with celiac disease: from the perspectives of children and parents

Aim. To examine how celiac children and adolescents on gluten-free diet valued their health-related quality of life, and if age and severity of the disease at onset affected the children's self-valuation later in life. We also assessed the parents' valuation of their child's quality of life. Methods. The DISABKIDS Chronic generic measure, short versions for both children and parents, was used on 160 families with celiac disease. A paediatric gastroenterologist classified manifestations of the disease at onset retrospectively. Results. Age or sex did not influence the outcome. Children diagnosed before the age of five scored higher than children diagnosed later. Children diagnosed more than eight years ago scored higher than more recently diagnosed children, and children who had the classical symptoms of the disease at onset scored higher than those who had atypical symptoms or were asymptomatic. The parents valuated their children's quality of life as lower than the children did. Conclusion. Health-related quality of life in treated celiac children and adolescents was influenced by age at diagnosis, disease severity at onset, and years on gluten-free diet. The disagreement between child-parent valuations highlights the importance of letting the children themselves be heard about their perceived quality of life.

Advances in coeliac disease

PURPOSE OF REVIEW

This article critically summarizes the recent scientific and clinical advances in coeliac disease.

RECENT FINDINGS

Epidemiological studies have shown that coeliac disease is as common in parts of Asia, Africa and Eastern Europe as in the western world. Genome-wide association studies continue to identify genetic susceptibilities that are both unique to coeliac disease and overlap with other autoimmune diseases. Human leukocyte antigen genotyping offers additional sensitivity in detecting coeliac disease in individuals who have self-prescribed gluten-free diets (GFD) or have atypical presentations. Immunological advances have highlighted the potential proinflammatory pitfalls of vitamin A supplementation in active coeliac disease and have enabled identification of oat and barley subsets that may be safely incorporated into coeliac diets. Large population-based studies have expanded our knowledge of the long-term risks of coeliac disease, in addition to excluding infertility as a cause for concern once a GFD has been established.

SUMMARY

The long-term implications of active coeliac disease emphasize the need for early detection and strict adherence to GFD, which remains the cornerstone of management. Technological advances in food modulation and immuno-therapies offer promise, but remain in the translational phases of clinical trials at present.
